Device for controlling at least one gas flow.

The invention relates to a device for controlling at least one gas stream which passes through at least one lockable by a liquid feed pipe which opens out with a downstream end and an upstream end in the liquid reservoir.

Such devices are known for example as traps. In this capacity they terminate normally from a foul-smelling gas over a tube end from which no odors to escape. Such traps are either opened fully. In this state, the liquid feed, the entire cross-section of the pipe for the passage of gas available. Or the liquid reservoir is filled. In this state, no gas can pass through the cordoned-off pipe. Control of the gas stream in the form that the gas streams can be shut off partially flow in one and partly in another direction or is not possible.

Object of the present invention is therefore to improve a device of the aforementioned kind so that with their help, a gas flow can be directed in one or more directions of a predetermined selection completely and partially.

This object is achieved in that the liquid reservoir has at least one controllable liquid outlet is arranged in the liquid reservoir at a height at most, on which is provided a connection between the downstream end and the upstream end.

Through this controllable liquid outlet as much liquid can discharged from the liquid receiver who the that the liquid reservoir releases a particular desired combination of downstream end and upstream end of a pipe. Depending on a particular desired direction of the gas stream to be steered each one or more inflow or effluent can be released from the liquid. Such a device has the great advantage of a very safe operation, because the gas inlet is always reliably closed to the downstream end. This reliability can be applied through the control of several on and flowing to a plurality of tubes.

According to a preferred embodiment of the invention at least two open oncoming on each different heights into the liquid reservoir. In this way can be connected to the downstream end by lowering a present in the liquid supply tank liquid level either one or the other upstream end. In this way, the gas stream can either be a flow in only one of two directions or in both.

It is also possible that both inflowing to the same heights in the liquid reservoir open out to let. In this case, both oncoming are released simultaneously so that flow out of two inflowing gas toward the downstream end.

According to a further embodiment of the liquid outlet to one end of a first leg is connected, which is connected via a yoke having a second leg of a UE-shaped pipe loop. The second leg is designed as a liquid outlet, the end of which is at most on a set by the end of the first leg level while lying between the two legs yoke is in the amount of an upper liquid Stan of the standing in the drain and upstream end liquid reservoir, wherein in the pipe loop is provided a their interior belüftendes after its opening shutoff.

Such pipe loop ensures optimum safety in the operation of the liquid seal, especially when the shutoff valve is formed in the yoke. In this way, the shut-off is located at the highest point of the U-shaped pipe loop. At this point, admitted through the air Absperrogang looks particularly at short notice to which outpouring by the U-shaped pipe loop quantity of liquid so that the liquid stream breaks off immediately after the opening of the obturator.

Further details of the invention will become apparent from the following detailed description and the accompanying drawings, in which preferred embodiments of the invention are for example illustrated.

A device essentially consists of a large container 1, a container 2 and a liquid reservoir 3.The container 2 is mounted in an upper part 4 of the large container 1 so that from it a liquid 5 can emerge by its own weight when a container 2 closing off valve 6 is opened.

Within the container 2, the liquid reservoir 3 is arranged as a pipe bend 7 of a pipe. 8 In the pipe bend 7 opens on the one hand a leading end 9 and on the other hand a downstream end 1o of the pipe 8. Due to the upstream end 9 a gas flows in the direction of the pipe bend 7, while through the downstream end of 1o the gas from the pipe bend in the direction of a negative pressure generating blower 11 flows. This blower is electrically powered and is due to an electric voltage source, not shown, when a float switch 12 is closed, the two electric poles are connected via respective lines 13,14 15,16 with the blower 11th

In the pipe bend 7, a liquid outlet 18 is provided at its lowermost point 17, through which the pipe bend 7 in communication with the container the second At the fluid outlet 18 closes in the direction of exiting the liquid outlet 18 of liquid 5, a pipe socket 19 at which protrudes with its the fluid outlet facing away from the bottom of 2o in an odor trap 21, which is provided in a container bottom 22nd This vessel bottom 22 separates the container 2 from the horizontal direction from the large container. 1 It is connected by a side wall 23 having a the bulk container 1 closing lid 24th Through the side wall 23 opens an inlet pipe 25 into the container 2 through this supply pipe 25, the fluid 5 is introduced into the container 2 from a power supply, not shown. The feed of the FLüssgkeit 5 controls a float valve 26, which is arranged in the feed pipe 25th This float valve 26 is equipped with a float 27 which floats on a standing in the large container 1 liquid quantity 28th

When full, the large container 1, the amount of liquid is 28 at level 29, whose height is measured within the large container 1 so that all the liquid can be taken out of the container 2 in the large container 1 without a discharge of liquid 5 from the container 2 is impeded.

The large container 1 has a liquid outlet 31 which is closed by a flush valve 3o. This liquid outlet 31 is provided in a bottom 32 of the large container 1, which extends in approximately plane-parallel to the cover 24th The liquid outlet 31 may be connected to an inlet 33 of a toilet bowl 34, which opens into the interior of the 35th In this combination, the bulk container 1 is designed as a flushing cistern, on the cover 24 an operating knob 36 of the flush valve is 3o provided. The interior space 35 of the toilet bowl 34 is connected via an odor trap 37 to a drain pipe 38th In this drain pipe 38, the downstream end opens 1o the liquid seal 3. In contrast, the upstream end is 9 4o connected via a pipe 39 with a hollow body, the extent protrudes on at least one side in the inner space 35, that he on with its mouth 41 as far as possible towards water trap 37 is located below the interior 35 of the toilet bowl the 34th on this hollow body 4o malodorous gases can be sucked directly above the trap 37 from the lower portion of the interior of the 35th

The liquid feed 3 separates the leading end 9 of the downstream end of 1o and prevents in this way that malodorous gases from the discharge pipe 38 on the downstream end 1o in the upstream end 9 and from there via the pipe 39 into the hollow body 4o and thus into the interior 35 of the toilet bowl can reach 34th Should consult the use of the toilet malodorous gases in the interior 35 of the toilet bowl to collect 34, they will be sucked by the blower 11 via the pipeline 39 toward the upstream end 9 when the liquid 5 from the container 2 and thus out of the liquid reservoir 3 has been drained. For this purpose is opened before using the bathroom features a pull knob 42 the valve 6, so that the liquid 5 can escape towards the large container 1 from the container. 2 In this way, emptied not only of the container 2 but also on the fluid outlet 18 the liquid seal 3. When leakage of the liquid 5 from the container 2 whose level 43 drops, so that the float switch 12 actuable float 44 drops with it and the poles 13,14 to one another. In this way, the fan 11 is switched on and sucks from the hollow body 4o the malodorous gases and presses it into the drainpipe 38th

If the inside 35 of the toilet bowl 34 is to be flushed, the flush valve 3o by raising the operating knob 36 is opened. Now, the entire amount of liquid which is composed of the originally present in the large container 1 liquid and the liquid contained in the container 2 5, enter through the inlet 33 into the interior 35, this rinse and drain through the odor trap 37 toward the drain pipe 38 , When draining the large container 1, the level 29 drops in the large container 1 and 27 with it the float through lowering of the float 27, the float valve 26 opens, so that new liquid through the feed pipe 25 may enter the vessel. 2 This is filled up to an upper edge 45 which is specified by a locking cylinder 46, which forms the valve 6th After this upper edge has reached 45, into the container 2 incoming liquid 5 passes through an overflow continues through the feed tube 25 into the large container. 1 This overflow 47 is provided on a valve 6 facing away from the upper end of the lock cylinder 46, so that by the overflow 47 effluent 5 may enter through the lock cylinder 46 in the large container 1 from the container. 2

With increasing rise of the liquid in the large container 1, the level rises 29 The supernatant at this level 29 float 27 actuates the float valve 26, as soon as the large container 1 has reached its fill. The float valve 26 closes the inlet pipe 25, so that no more liquid 5 may enter the vessel. 2

Instead of a pipe bend 7 a division 84 of the container 2 may be formed as liquid feed. 3 This is divided into two sub-divisions by a partition 87th The partition wall 87 extends from the cover 24 toward the container base 22 and projects with its lid 24 remote from the end 88 in the standing up to overflow 47 liquid 5. In contrast to stand at the two subdivisions of the end 88 in the container 2 is lowered liquid level together in connection.

In one of the two subdivisions opens at an above standing on overflow 47 upper liquid level footwall first point 85 the downstream end 1₀While in the other subdivision of the upstream end 9 opens above the standing on overflow 47 upper liquid level at a second location 86th The division 84 is opposite a remaining interior 9o of the container 2 separated by a wall 89 which extends towards the container base 22 from the cover 24 and facing with its tank bottom 22 lower end 91 short ends over this, so that this lower end 91 projects into the odor trap 21st In this way prevents odors from the department 84 can enter the rest of the interior of the container 9o.

Instead of a Anströmendes 1o also two spatially separated inflowing 48,49 may be provided which are both connected to the downstream end 1o. This connection can be provided at the same level, so that when the fall of the liquid 5 in the container 2, the two inflowing be 48,49 simultaneously connected to the downstream end 1o. It is for example conceivable that the same malodorous gases can be sucked through both the hollow body 4o and at one the siphon trap 37 remote from the upper edge of the toilet bowl 5o 34 by an unshown special pipe.

However, it is also possible to leave the upstream end 48 open out on a higher level 51 in the downstream end 1o when the debouching at a lower level 52 upstream end 49. In this way, during the lowering of the liquid 5 in the container 2 is first a connection between see the upstream end 48 and the downstream end 1o produced. Only after a further lowering of Flüsigkeit 5 in the container 2 is also on the lower level 52 a connection is established between the upstream end 49 and the downstream end 1o so that now also gases are sucked from the upstream end 49th Such a connection between the upstream end 49 and the downstream end 1o on the lower level 52 is optionally then be considered if in a sucked through the upstream end 48 gas stream certain preconditions are met, for example, a predetermined enrichment odorants is exceeded. Only when this condition is satisfied, there is a further lowering of the liquid 5 in the container 2 up to the lower level 52. In this way, after reaching this condition, the gas across both inflowing 48,49 are aspirated.

However, the liquid reservoir 3 may also be arranged directly in the large container 1, so that the arrangement of a container 2 is omitted within the Großbehätters. 1 In this embodiment of the invention the Flüssigkeitsvorlage3 for the extraction of gases from the upstream end 9 is thereby released toward the downstream end 1o that existing in the large container 1 liquid level 29 is lowered to the extent that from the liquid reservoir 3 all liquid has drained off. For this purpose is the liquid reservoir 3 at its lowest point 17 via a liquid outlet directly to the large container 1 in conjunction. This liquid outlet 18 may, however, lead to a pipe socket 19, which opens facing away with his the liquid outlet 18 lower end 2o in an odor trap 21, which is fixedly connected to the bottom 32 of the large container 1 and filled with liquid 28 remains when the contents of the has large container 1 otherwise flowed through the flush valve 3o.

The liquid reservoir 3 may be slidably mounted within the large container 1 in the vertical direction. The pipe bend 7 is connected in this case via bellows 67,68 with the leading end 9 and the downstream end 1o. These bellows 67,68 are with filled liquid reservoir 3 in a stretched state 69 and emptied liquid reservoir 3 in a compressed state 7₀,

The pipe bend 7 relies on its side facing the free-stream and downstream end 9,1o outside facing away from 71 on floats 72.73 from floating in the liquid 5 and are slidably mounted in the vertical direction on guides 74,75. On its outer side 71 opposite inner side 76 of the pipe bend 7 is connected to a fixing device 78 that protrudes with a handle 77 of the lid 24 of the large container. 1 This locking device 78 consists essentially of a rod 79, which is fixedly connected to the handle 77 and facing away from her the handle 77 the lower end 80 has a lock that can be within a guide tube 81 either locked or released by pivoting. The guide tube 81 is fixed to the inner side 76 of the manifold 7 and is guided in a sleeve 82 which surrounds the rod 79 and is fixed to the cover 24th In the lowered state, the float 72.73 the locking device 78 falls automatically to its locked position.

On its outer side 71 of the manifold 7 is penetrated by a fluid outlet 18, to which a pipe socket 19 connects in already known manner, which opens with its lower end 2o in an odor trap 21, which is mounted on the bottom 32 of the large container. 1

ei unlocked detent 78 72.73 swim floats on the liquid 5 and lift the liquid reservoir 3 from the liquid 5 out, so that the standing in the manifold 7 Flüsigkeit 5 can escape through the fluid outlet 18 toward the large container. 1 After emptying of the manifold 7, the upstream end 9 is connected to the downstream end 1o via the blower 11 so that gases can be sucked through the pipe eighth

If the level 29 by opening the purge valve 3o lowered sink the float 72.73 with exiting the fluid outlet 31 from the liquid until the Faltenbälte have 67.68 adopted its stretched state 69th In this position the detent 78 snaps into its lock, so that floating of the float is 72.73 prevented if recently fluid 5 enters through the inlet pipe 25 into the large container. 1 through the liquid outlet 18 is now running the extending below the level of 29 liquid reservoir 3 full liquid 5 and thus cuts off the leading end 9 of the downstream end 1o.

Should more recently gas are sucked through the tube 8, the handle 77 is pivoted so that the locking device 78 is released from its locked position. Now, the swimmers can float 72.73 in the liquid so that an emptying of the liquid feed can take place. 3

On one of the float 72 a connecting rod 83 is attached, which connects to the float switch 12 in the raised position of the liquid seal. 3 In this raised position, the fan is turned 11 on the float switches 12th The bellows 67,68 are in their compressed state 7₀,

The apparatus for controlling gas streams can be found 34 use also outside the flushing of the toilet bowl. For example, it must be remembered that a contaminated gas stream to be sucked according to the strength of its contamination on one or more oncoming. 9 Such a device consists essentially of a provided with an upstream end and a downstream end 9 10 pipe 8 and a pipe loop 104. The tube loop 104 is U-shaped and has a tube 8 connected to the first leg 1₀5 and a second leg 106 which are connected to one another via a yoke-107th The second leg 106 has an opening into an outlet end 108 1₀9, on the one flowing out of the pipe 8 fluid 5 can be discharged.

In contrast, has the first leg 1₀5 a the yoke 107 opposite end 111 which opens through a connecting pipe 112 in a liquid collector 113th This is designed as a vessel into which the liquid is 5 introduced via an inlet 114th This inlet 114 is controlled by a valve 115 and optionally connected to a water network, not shown, or separated from it. The inlet 114 flows into the liquid receiver 113 on the underside 117 a with a vertical hinged upward Spritzende 118th Immediately oberhald this Spritzendes 118 closes in the direction of emerging from the injection end 118 liquid jet 119, a cage 116 to, in which a ball is 12o movably guided in the vertical direction. The cage 116 has walls 121 that the ball 12o surrounded by a relatively narrow margin 122nd

The cage 116 is closed at its side facing the spray end 118 facing bottom 123 of a bottom plate in which an opening 124 is provided. This opening 124 lies in the direct spray of liquid jet 119 so that it impinges by its passage through the opening 124 facing to the bottom 123 lower surface 125 of the ball 12o and this raises towards emerging from the injection end 118 liquid jet 119 toward a bottom 123 opposite top surface 126 of the cage 116. at this top surface 126 of the ball 119 lies 12o under the influence of the liquid jet at a associated with the top surface 126 of support 127 with its bottom surface 125 of the surface 128 at abgewanden. The top 126 is permeable to the liquid 5, for example in the form of a star-shaped extending webs. It is also possible to form the upper surface 126 in the form of a sieve.

In the direction of entering the cage 116 liquid jet 119 has subscribed to the cage 116, a further cage 129 at which on its side facing the lower cage 116 bottom 13o is permeable for the liquid. 5 On this sub-13o is a ball 131 having a specific gravity similar to that of the ball 12o about equal to the specific gravity of the fluid. 5 The upper cage 129 opens with a in the form of a cone extending side surfaces 132, 133 in a space enclosed by the tube 8 interior 134th The side surfaces 132, 133 have an inclination which causes the side surfaces 132, 133 extend approximately perpendicular to a direction 135, below the passing a gas stream through the tube eighth The side faces protrude 132, 133 in a the leading end 9 connected to the downstream end 1o manifold 136 into it, so as to extend approximately perpendicular to the direction 135 of the deflected in the manifold 136 gas stream.

In the side faces 132, 133 through openings 137, 138 are provided, through which the gas stream from the upstream end 9 extends towards the downstream end 1o. These passage openings 137, 138 have a cross section which is smaller than that of the ball 131, so that the protruding with domes 139,14o in the passages 137,138 ball 131 through openings 137, 138 in liquid-tight closes. Similarly, the opening 124 is formed with respect to the ball 12o, so that the resting on the bottom 123 ball 12o, the opening 124 closes off liquid-tight.

When filling of the tube 8 shown in Figure 8, the valve 115 is opened so that the liquid jet 119 enters the liquid receiver 113 and the cage 116th He thereby lifting the ball 12o so far indicates that the opening 124 is released for the entry of liquid 5 in the two cages 116, 129th In this way, the liquid 5 may freely in the two cages 116, rise 129th Under the influence of ascending in the cage 129 liquid 5 of the ball is pressed 131 in a space 141, which is arranged between the openings 137, 138 facing away in a cage 116 upper part of the cage 129th In this free space 141 of the ball 131 is held under the influence of liquid sigkeitsstrahles 119 in a stable position, so that the liquid at the Durchtrittöffnun- gen 137, 138 non-occluding in this position surface of the ball 131 passing through the through-holes 137 , 138 can flow into the upstream end 9 and the downstream end 1o. It fills in the field of buying and flowing off from 9,1o the entire cross section of the tube 8, so that the standing in the leading end 9 and downstream end 1o liquid 5 a liquid reservoir forms, the passage of the flowing in the tube 8 gas from the upstream end 9 in the downstream end 1o prevented.

The replenishment of the arrival and flowing off 9,1o carried to a height 142 in the yoke 107 of the pipe loop 104 is. During the filling of the tube 8 with liquid 5 an obturator 143 is opened by the air from a the obturator 143 surrounding space via a pipe socket 144 in the yoke 1₀7 opens. In this way passes through the obturator 143, an air flow in a loop through the tube 1₀4 pouring forth liquid stream 145 a, so that it can be introduced through the second leg 106 in the sequence 108, if not in time, the valve 115 is closed. After closure of the valve 115, the fluid remains 5 with its upper level 146 are equal to the yoke 107 without a depletion of arrival and flowing off 9,1o carried by the pipe loop 104th

9,1o For the purpose of emptying the arrival and or flowing off the obturator 143 is initially closed, so that now no more air in the yoke 1₀7 may occur. Then again briefly liquid 5 is flushed through the valve 115 into the liquid receiver 113, so that the level 146 rise so far that the entire yoke 107 is filled with fluid. 5 After filling of the yoke 1₀7, the liquid flows through the second leg 106 in the direction to the flow 1₀8. about lying in the vertical direction below the end 111 109 end of the second leg 106 enters the liquid from the liquid receiver 113 and thus from the purchase and downstream end 9,1o with the conduct 108th The liquid can be 5 pour through the unsealed by the ball 131 through openings 137, 138 therethrough. The ball 131 thus drops toward the bottom of the cage 13o 129th

To prevent the ball 12o to the opening 124 Sets and closes with respect to the liquid receiver 113, the ball is 12o kept in suspension within the cage 116 through the fluid jet 119th The case passing into the liquid receiver 113 Flüsigkeit is 11o through the pipe loop 104 in R.ichtung on the course 1₀8 sucked.

This liquid feed can find use in a tube 8, which is either a positive pressure or a vacuum. For example, the downstream end 1₀ generates a vacuum, so the ball moves 131 from the space 141 toward the passage opening 138, through which it protrudes with the dome 139th He thereby closes the passage opening 138 liquid-tight, so that no liquid from the downstream end 9 and the cages can be 116, 129 sucked. Depending on whether a water jet 119 hits from the inlet 114 to the ball 12o, this is lifted from the mouth 124th The respective position of the ball 12o for the function of the liquid reservoir is irrelevant.

On the other hand, it is conceivable to generate an overpressure in the upstream end 9 of the tube eighth This excess pressure pushes the ball 131 from the space 141 in the passage opening 137, so that it protrudes with a cap 14o in the downstream end 1o. In this position, the ball seals 131 through opening 137, so that the pressure can not propagate into the downstream end 1o. Rather, the pressure in the cages 116, 129 expands and pushes the ball 12o in the opening 124 of the cage 116. From this opening 124 protrudes the ball 12o with a cap h_er-out, so that the ball in the opening 12o a 124 _Abdich- device is produced, which prevents the pressure propagates in the pipe loop 104th In this way, the liquid remains in the upstream end 11o 9 are without being forced out via the pipe loop 104 toward the drain 108th

In principle, it is also possible to the cages 116, 129 to be arranged in the horizontal direction next to one another, wherein the direction of movement of the balls 12o, 131 respectively in _RI- direction of passing through the cages 116, 129 Wing_s- Fluid 5 passes. In this case, therefore, also to ensure that the liquid jet 119 extends horizontally through the cages 116, 129th

A pipe loop 104 can also be applied for controlling an amount of water 164 using that in a container _the is. 2 This container 2 is provided inside a flush tank 166, in which a quantity of flush water 167 is introduced, which is used to purge a Toilettenbekkens 34th For this purpose, the cistern 166 is connected via a flush pipe 169 with the toilet bowl 34, 5o opens the flush pipe 169 in the upper part thereof. This is compared to the cistern 166 closed by a flush valve 3o, which can be opened or closed via an operating linkage 172nd This linkage system stands out with an operating knob 36 from the cistern 166th between the actuating rod 172 and the purge valve 3o extends an overflow pipe 174, on the one hand connected to the actuator rod 172 and the other to the flush valve 30th This overflow pipe 174 are equal to one in the cistern 166 maximum attainable water level 175 overflow openings 176 through which the rinsing water can 167 enter into the overflow pipe and from there into the flush pipe. The overflow pipe is the flush pipe 169 continues toward the actuation linkage 172nd

For flushing of the toilet bowl 34 of the operating knob 36 is raised, and thus the flushing valve opened 3o. This allows the existing within the cistern 166 amount of water entering through the flush pipe 169 into the toilet bowl 34 and this rinse, so that an existing in the toilet bowl 34 wastewater 177 closure via an odor trap 37 can drain into a sewer 38th The time available for this purpose of flushing water 167 can be increased by the additional amount of water 164 which is in the container 2. For this purpose the amount of water is flushed 164 via the pipe loop 104 in the cistern 166th To conduct this Einspülung in the way, the entire pipe loop 104 is filled with water, so that the amount of water 164 enters the first leg of the pipe loop 104 and is sucked through the second leg 106 towards the cistern 166th The end 109 of this second leg 106 is located below the opening into the container 2 111 end of the first leg 1₀. 5

The filling of the pipe loop 104 takes place by means of a filling device 180 which is connected via a lead 181 to a not shown water mains. This Befültungsvorrichtung 18o essentially consists of a spray pipe 182, which, with its injection end 183 immediately at the end 111 of the first leg 1₀5 ends. Zwischem the Spitz tube¹⁸² and the feed line 181 Is a control valve 184, which has a projecting out of the container 2 and the flush tank actuating button 166 185th By means of this operation knob 185, the control valve 184 is opened so that water from the supply line 181 to enter the spray tube 182 and from the injection end 183 can enter the end of the 111th Through a tripped by means of the operating knob 185, the surge in the first leg 1₀5 standing volume of water driven away through the yoke, so that the first leg 1₀5 standing water quantity in connection with the second leg 1₀6 standing water quantity found. In this way, the pipe loop 104 forms a water fountain, of the total amount of water 164 from the_BehäL- ter 2 promotes the cistern 166th In this way the flushing water rises in the cistern 167 at the upper water level 175th You is now available for the execution of a large flushing available.

The container 2, the tube extends 8 with its leading end 9 and its downstream end 1₀, It projects with its manifold 136 in the standing container in the 2 amount of water 164, so that it forms a liquid seal.

The upstream end 9 is connected via a connecting pipe 186 with a vent line 187 in connection, which passes through the cistern 166 and with its upper end 188 terminates above a lower water level 189 of the standing in the cistern 166 flushing water 167 in a bell 19o. This bell 19o has a ventilation pipe 187 facing open bottom surface 191, through which protrudes the upper end 188 in the bell 19o. This emerges with its open bottom surface 191 surrounding edges 192 into the flushing water 167, so that a space enclosed by the bell 19o interior 193 no gases can penetrate into the cistern 166th

In this way it is possible to produce by means of a generated by a fan 194 in the tube 8 vacuum in the vent line 187 a directed from the toilet bowl 34 toward the bell 19o exhaust stream this via the connecting pipe 186 into the upstream end 9 and from occurs when emptied container 2 into the downstream end 1o. This air stream is then conveyed from the blower 11 through the pipe 8 into the sewer line 38, with which the pipe 8 is connected.

In addition, projects into the bell 19o through their open bottom surface 191 into the overflow pipe 174 with its overflow openings 176th Since this overflow pipe 174 protrudes from the lower level 189 and the upper level 175 of the flushing water 167, can be sucked out of the Toilettenbecken34 also about this overflow pipe 174 exhaust air via the flush pipe 169th This possibility is particularly exercised, if it should turn out that a protruding into the toilet bowl 34 lower opening 195 of the vent line is clogged 187. In this case, although the air is not sucked to the lower opening 195, but in the region of the upper portion 5o of the toilet bowl 34. Although these 5o takes place in the upper part of suction is not as effective for the exhaust ventilation as that in the lower opening 195, but eliminates a lot of the emerging in the toilet bowl 34 exhaust.

The bell 19o (Fig. 1₀) Can also be configured as the active control part for the odor trap. In this case, both the upstream end 9 and the downstream end 1o are passed through the bottom of the cistern 166 constructed as bulk storage tank 1 in which is provided with floats 172,173 and lowered configured bell.

The bell has 19o in its dome 178 a projecting toward the water level 189 partition 87, which is mounted on a the Wasselpegel 189 facing inside of the dome 178th The upstream end 9 and²⁰the downstream end 1o protrude above the water level 189 out into the bell 19o. Between the upstream end 9 and the downstream end 1o extends the partition 87 in the lowered position of the bell 19₀When it is held in place by the detent 78th Once the locking device is released 78, swim floats 172, 173 of the bell on 19o. Thus, the partition 87 is lifted out of the water level 189th Between the partition 87 and the water level 189 of the path from the upstream end 9 is released to the downstream end 1o inside the bell 19o. After pressing the purge valve 30, the amount of water contained in the cistern Expires 167 and the bell 19o falls back into its lower end position, where it is again fixed by the detent 78th The bell 19o is provided in its dome 178 with openings 179, are guided by in the lowered state, the leading end 9, the downstream end of 1o and a partition 87 sealingly. In this position the connection between the upstream end 9 and the downstream end 1o is locked. If the bell unlocked 19o a she retentive in the lowered position detection device 78, such floating on the guided tours at 74.75 in the vertical direction bell 19o and are the link between upstream end 9 and the downstream end 1o free. After pressing the flush valve 3o the amount of water contained in the cistern Expires 167 and the bell is lowered back into its lower end position, where it is again fixed by the detent 78th

The overflow pipe 174 has in its lying between the flush valve and 3o the overflow openings 176 central region 196, a constriction 197 of its cross section. This constriction leads 197 within the overflow pipe 174 to a desired increase in the flow resistance, so that within the overflow pipe 174 only with respect to the vent line 187 relatively small air flow is achieved. In this way is to ensure that the essential part of the exhaust air is sucked through the vent line 187 to the lower opening 195th For this purpose also serves as a connecting piece 198 that extends between the irrigation tube 169 and the vent line 187 and connecting to the flush pipe 169th This connector 198 is oblique to the direction of the vent line 187 and has a slope in the direction of passing through the flush pipe 169 exhaust flow. In this way it is achieved that a part of entering through the lower opening 195 exhaust air is sucked through the flush pipe 169 in the bell 19o. In addition, the connector 198 of the flushing water 167 opens up the possibility to be flushed to a part on the ventilation line 187 into the toilet bowl 34th This passing through the vent line 187 subset of the rinse water 167 causes a flushing of the ventilation pipe in the lower opening 195, so that it is purged of impurities, which could have possibly accumulated during the exhaust ventilation in front of her. In addition, syphoning of the odor trap 37 sert significantly improve in the waste water 177 through the deep and direct entry of Spülwasserteilmenge, so that there is a much faster and wider Preispülung the trap 37 and the sewer pipe 38th

Before using the toilet the operating knob 185 is pulled and thereby actuates the control valve 184th This in the end 111 of the first leg 1 enters an amount of water through the spray end 183₀5 and brings about water fountain formed the pipe loop are used. To prevent Druckströße to the water mains, the control valve can be provided 184 with a delay 199, by a sustained surge is generated in the Befütlungsvorrichtung 18o. Moreover, it is · possible to provide an anti-vacuum device 165 in the supply line 181 and with the aid of air to suck in an amount of water that brings the water fountain formed by the Rohrschteife 104 for use on the filling device 18o.

This promotes the amount of water 164 in the toilet tank 166 so that is in this one extending to the water level 175 flush water available. After the expiration of the control valve 184 from the container 2, the leading end 9 is connected to the downstream end 1o through the manifold 136 in conjunction. In addition, a float switch 12 has turned on, the fan 11 so that this Abtuft about the downstream end 1₀can, the leading end 9 and the connecting pipe 186 from the bell 19o and thus the toilet bowl 34 aspirate. The float switch 12 is in control communication with a floating on the water volume 164 float 27 which has dropped after draining the amount of water 164 on the Rohrschteife 104 and thus has the float switch 12 is closed.

After completion of the toilet using the operation knob 36 is pulled out of the cistern 166 and thus the flushing valve opened 3o. With this flush valve 3o Runs the flushing water from the cistern 167 166 for the purpose of flushing the toilet bowl 34 and flushes this. With reduced water level 175, a float drops 27 downwardly and opens with it mechanically connected filling valve 26. This connects an inlet 25 with a water network, not shown. This inlet 25 protrudes into the container 2 into and fills it with the amount of water 164. Once this is reached in the container 2, the container 2 incoming water enters through the inlet 25 via an overflow pipe 16o in the toilet tank 166 until it up is filled to the lower level 189th Once this level is reached 189, operated the float 27, the filling valve 26, so that it separates the inlet 25 from the water supply and thus prevents further filling of the cistern 166th Moreover, the float 27 is floated on the water volume 164 and has a float switch 12 is opened, so that the blower 11 is switched off.

To prevent while using the toilet a filling of the container 2, which can optionally take place by inadvertently entering the container 2 amount of water in a leaky filling valve 26, having the fill valve 26 a fitment outlet 161, which is directed into the cistern 166th This is Weie prevents a 26 exiting amount of water passes through a leaky filling valve into the container 2 and with this also between the upstream end and the downstream end 9 1₀ existing liquid reservoir fills. This arrangement of the Tropfauslasses 161, which is arranged in the vertical direction below the feed 25, it is ensured that during the entire use of the toilet an air passage between the upstream end 9 and the_From- Flowing 1o there.

The overflow pipe must 16o with his project into the container 2 top 162 in the vertical direction below a predetermined height from the yoke 107 beds. In this way it is prevented that during the filling of the container 2, the entire pipe loop 104 fully Runs water and the amount of water unintentionally 164 runs this way about the water acts as a siphon loop 104 in the cistern 166th For this reason, the upper end 162 must be located as far below the yoke 107, that this does not flow through during the filling of the container 2 of water.

In addition, care must be taken that the upstream end 9 is not immersed in its entire length in the amount of water 164 of the container. 2 Rather, 163 must be provided between the connection pipe 186 and the upstream end 9, a pipe bend, which extends in the vertical direction higher than the upper end 162 of the overflow tube 16o. In this way it is prevented that when filling the container 2 water on the upstream end 9 and the connecting pipe 186 runs in the cistern 166 and optionally in the vent line 187 before the container 2 is filled to its intended level with water. Moreover, it should be ensured that the elbow 163 in the vertical direction above a yoke from 1₀7 predetermined plane.

Instead of a formed as water siphon loop 104, the container 2 with a pump 92 may be provided that the amount of water 164 fö in the cistern 166_r- Changed. The pump 92, in a in a first compartment 84 and a remaining interior 9o divided container may be housed both in the first compartment 84 than the rest of the interior auchin 9o.
