Best way to carry out the invention

Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

With reference to FIG. 3, a preferred embodiment of a washing machine according to the present invention will be described. Especially, since the present invention is about a washing machine that uses steam, a schematic configuration of the present invention will be described, focusing on a steam generator.

A washing machine according to the present invention includes a steam generator 100, a water supply path 200, a steam path 500, and a control assembly 400.

The steam generator 100 supplies steam to a drum 30. Therefore, it is preferred that an outlet of the steam generator 100 be in communication with the drum 30.

The steam generator 100 has a heater 110 for heating water, and the heater 110 may be a coil heater, a coated heater or an induction heater.

The water supply path 200 is connected to the steam generator 100 and to a tank (a drum).

The water supply path 200 is connected to a water source, such as a tap. Water supply valves 310 and 320 are provided, each in the water supply path 200 to selectively open / close the water supply path 200. At least one of the water supply valves 310 and 320 controls the supply of wash water to the steam generator 100.

On the other hand, the steam path 500 is connected to the steam generator 100 and supplies steam generator in the steam generator 100 to the drum 30. That is, a first end of the steam generator 100 is connected to the steam generator 100 , and a second end thereof is connected in communication with the drum 30.

The control assembly 400 controls the operations of each component in the washing machine, and includes an option selection part 410, a program selection part 420, a steam selection part 430 and a controller 440.

With reference to FIG. 4, the control assembly 400 will be described.

The program selection part 420 is for a user to select a program from several programs. The program selection part 420 could include a selection device structure, such as a turn control 421 to deliver a selected signal after detecting if a program has been selected by means of a turn. That is, preferably, a program is selected based on the angle of rotation and the direction of rotation of the rotation control 421. The program selection part 420 may be a touch panel.

The programs provided by part 420 of the program selection could include a fabric type program, such as wool, synthetic and bedding, a standard program, a cooling program (soda), a washing program of the tank / of the drum and a sanitary program. The cooling program (soda) is mainly to eliminate wrinkles from the laundry using steam. A procedure for carrying out the cooling program can be achieved in several ways and the detailed explanation is omitted. The cleaning program of the tub / drum is to sterilize and wash the tub / drum by supplying steam without water in the drum. Programs are not limited to what is shown in FIG. 4, and can be varied, alternatively, depending on the washing machine. For example, another washing program may also be included according to a very dirty laundry condition.

Preferably, when steam is supplied to the drum, the drum is turned over. Turning means that the drum is rotated at a lower speed, so that the laundry is not fixed to an internal wall of the drum by means of centrifugal force. That is, the turning speed for the turn is not greater than 1G (acceleration of gravity). The drum could be rotated in one direction clockwise / counterclockwise. On the other hand, it is preferable to rotate the drum alternately at a high speed of more than 1 G and turn the drum during general washing programs.

Part 41 option selection 0 is for operational details of each wash program, and includes a plurality of buttons that provide selected signals to the controller 440 after detecting whether a user presses the buttons. For example, each button of option selection part 410 may include at least one of the buttons, such as a wash button 411 to select a wash program, a rinse button 41 to select number of rinse, a button 413 of speed to select the speed of rotation of the drum, a button 414 of the temperature of the water, a button 415 of dried. Preferably, a steam regulation button 416 is provided to regulate the various options (factors) of steam generation. The steam regulation button 416 can be considered as a type of an option selection part.

Although it is not observed in the option selection part 410, an electric bulb is turned on / off in the event that a program is selected, in which steam could be used, by means of the operation of the selection part 420 of the Program. Alternatively, instead of buttons, the term "button" is used herein only for the sake of convenience.

On the other hand, the steam selection part 430 is for selecting the operation of the steam generator 100. The steam selection part 430 can transmit the selected signal to the controller 440 after detecting if the user presses the option selection part, or can transmit the selected signal to the controller 440 after detecting when a user selects the selection part 420 of the program Alternatively, the steam selection part 430 can transmit the selected signal to the controller 440 after detecting if a user presses the option selection part and detecting when a user selects the program selection part 420.

The steam selection part 430 may have types of buttons, so that a user may select to operate the steam generator 100. The corresponding selected signals are generated in program selection part 420 when each wash program is selected. The selected signals are detected by a detection part (not shown) and are transmitted to the 440 controller. Here, the detection part can be an A / C converter or an input / output interface, so that it detects exactly which wash program is selected. In addition, the detection part may be connected to the steam selection part 430 or the controller 440. The control system can be achieved to detect and transmit the signals.

selected in many ways and could be known by the person skilled in the art, thereby omitting the specific description thereof.

According to the present invention, the controller 440 controls the steam generator based on both an introduced (selected) washing program with the user selection part 420 (later, an introduced washing program) and an instruction of use of the steam introduced (selected) with the steam selection part 430 by a user (later, a steam selection signal). Therefore, the operation of the steam generator 100 is not necessary in all types of washing programs. For example, it is not necessary to use steam in wool and sheet / pillow washing programs, because wool and sheets / pillows are heat sensitive. In addition, if steam comes into contact with these types of tissues, the tissues may be damaged. Consequently, preferably, in order to avoid confusion of a user, the steam generator is not operated when a program is carried out in which the operation of the steam generator is not necessary, even if the user selects the part 430 for selecting the steam.

Therefore, according to the present invention, the controller 440 controls the steam generator 100 to generate steam, only in the case that the washing program introduced is a predetermined washing program as a washing program using steam (below , a steam wash program).

The feature of the present embodiment described above can be implemented in various ways. For example, the steam selection signal is transmitted to the controller 440, only in the case where the washing program introduced is the steam washing program. Alternatively, even a steam selection signal is transmitted to the controller 440 regardless of whether the washing program introduced is a steam washing program, and the steam selection signal can be ignored in the event that the program The washing program introduced is not the steam wash program.

In the following, for the sake of a precise description, it will be implemented below that the input signal selected in the steam selection part 430 is transmitted to the controller 440 only in the event that an introduced washing program is a steam washing.

According to the present invention, the steam selection part 430 is according to each washing program selected in the program selection part 420, which means that the controller 440 is selectively connected with the steam selection part 430.

Here, the expression <selectively operated> may mean that the mechanical operation of the steam selection part 430 is carried out selectively and may also mean that the transmission of signals between the steam selection part 430 and the Controller 440 is carried out selectively regardless of the mechanical operation of the steam selection part 430. In this case, the transmission of signals between the controller 440 and the steam selection part 430 is activated, in the event that an introduced washing program can carry out steam washing. On the other hand, the transmission of signals between the controller 440 and the steam selection part 430 is disabled in the event that an introduced washing program cannot carry out steam washing.

The 440 controller is programmed to operate only when both conditions are satisfied. The two conditions are: one, in which a washing program introduced is a steam washing program capable of using a selected washing program when marking the selection part of the program; and the other, in which the steam selection part is selected.

As mentioned above, the steam selection part 430 is operated selectively based on the selection of the program selection part 420, and, alternatively, the steam selection part 430 can be operated in a manner selected based on the selection of option selection part 410.

Another embodiment according to the present invention will be described below.

The control assembly 400 includes a means 450 for displaying the steam wash selection to alert a user that it is possible to select whether he / she can select the steam selection part 340. Preferably, the means 450 for displaying the steam wash selection uses an electric bulb that is selectively switched on / off.

The operation of the display means 450 of the washing section is activated with the control of the controller 440 in the event that a washing program introduced is a steam washing program. At that time, a steam washing program can be at least one of the programs, such as a standard program, for cooling and washing the drum / the tank.

The controller 440 of the control assembly 400 controls the operations of the heater 110 as well as of each water supply valve 310 and 320 based on signals received from the steam selection part 430. Alternatively, as described above, the controller 440 can read an introduced wash program selected by the program selection part 420, and also controls the means 450 for displaying the steam wash selection to be activated in the case the washing program read

Be a default steam wash program. Even if the steam selection part 430 is selected, the steam generator 100 is controlled so that it is not operated in the event that a washing program introduced is a program in which it is impossible to control the steam generator 100 as it has been predetermined.

Preferably, a steam regulation part is also provided to select at least one of a steam start time, an amount of steam, a degree of steam injection and a steam generation time. Of course, when several factors of steam generation are regulated, the performance of steam washing can be differentiated, but an energy saving function can be satisfied.

The steam regulation part can use the steam selection part 430. Preferably, an auxiliary steam regulation unit is provided and may be a steam regulation button 416. The steam regulation button 416 may be a type of an option selection part 410.

It is possible to regulate various types of factors in the steam regulation part, preferably an amount of steam. For example, at least one is selected from an economic steam, a turbo steam, and a small amount of steam in the steam regulation part. In addition, once a steam operation is selected that requires a relatively large amount of steam, for example, an economical steam and a turbo steam, it is preferred to operate the steam generator until the temperature of the drum reaches a preset temperature. In addition, once a steam operation is selected that requires a relatively small amount of steam, it is preferred to operate the steam generator for a predetermined period of time. It is possible to use a heater to heat wash water as a heater to heat the drum. Alternatively, other heaters can be used.

Another embodiment of the present invention will be described as follows.

Preferably, an indicator 422 is also provided in the program selection part 420 to alert a user of what washing program is a steam washing program. Therefore, a user cannot be confused, because he can recognize a steam washing program in advance.

The 422 indicator can use an LCD, an LED and an electric bulb. It is easy to notify the user when using the term <VAPOR> provided in the control set, as shown in FIG. 4. Preferably, the letters <VAPOR> are printed on the surface of the control assembly. [69] A means 460 for displaying the steam wash is provided in the control assembly 400 to notify the user that a steam wash is taking place. Here, the steam washing display means 460 may be an LCD and an LED, but preferably it is an electric bulb that turns on / off during steam washing.

With reference to FIGURES 3 to 5, a method for controlling the realization of the washing machine according to the present invention will be described.

First, the washing machine is operated by the user-operated buttons and rotary control, and the 440 controller could check these types of operations (S110).

Once a wash program has been selected in a user-operated program selection part 420, the controller 440 checks which wash program is selected (S120).

It is determined whether the selected washing program (introduced) can control a steam generator 100, that is, one of the steam washing programs (S130) is selected. This is done by comparing the washing program introduced with the steam washing programs determined and stored in the 440 controller.

If the washing program introduced is a steam washing program, the controller 440 turns on a means 450 for displaying the wash selection, for example, an electric bulb, to alert a user that the selection part can be selected of steam Therefore, a user can select if steam is used (S140). Along with that, the signal transmission between the controller 440 and the steam selection part 430 is activated. Alternatively, as described above, it may always be possible to transmit signals between the controller 440 and the steam selection part 430, and the controller 440 can ignore the selection of the steam selection part 430 in the event that The washing program introduced is not a steam washing program.

On the other hand, in the case that the washing program introduced is not a steam washing program, an electric bulb 450 is not lit and the user is not asked to select the steam selection part 430 (S180). However, a user can select the steam selection part 430. However, according to the present invention, it is not considered substantially a signal that the steam selection part has been selected by the user when the washing program introduced is not a steam washing program. Here, preferably, a user is alerted that it is not appropriate to select the steam selection part 430. For example, an error message is displayed visually or an acoustic signal (or a voice message) sounds.

The 440 controller checks whether a user selects the steam selection part 430 (S150). In the event that the user has selected the steam selection part 430, steam is supplied to a drum to carry out a steam washing program selected according to the predetermined algorithm (S160).

For example, if a user selects both a standard program and the steam selection part, the controller 440 controls the washing machine based on the algorithm for the standard program and steam generation. The controller 440 controls a drum (not shown), water supply valves 310 and 320 and a heater 110 of a steam generator 100 to carry out the corresponding program. At that time, it is preferable that the water supply valve 320 is a solenoid valve, and that the switch is a contact switch that the controller 440 causes selectively to come into contact with a current terminal. More specifically, once a steam washing signal has been introduced by means of the steam selection part 430, the water supply valve 320 is controlled to supply a predetermined amount of water to the steam generator 100 via the controller 440 through a water supply path 200. In addition, the switch is controlled to supply power to the heater 110 of the steam generator 100 by means of the controller 440. Here, a water level sensor is provided in the steam generator 100 to measure a level of water supplied thereto. Therefore, once the predetermined water level is reached, a water level is supplied to the heater 110. Alternatively, once the water supply valve 320 is opened to supply water to the steam generator 100 for the predetermined period of time, the energy to be automatically supplied to the heater 110 can be controlled by means of the controller 440.

On the other hand, when the steam wash program is in progress, a steam washing display means 460 provided in the control assembly 400 is turned on to alert a user that a steam wash is in progress.

In the event that the user has not selected the steam selection part 430, the washing program operates on the basis of predetermined basic algorithms, that is, when the steam generator 100 is not controlled. At that time, the steam washing display means 460 of the control assembly 400 is not turned on to alert the user that steam washing is not in progress.

Once the wash program has been completed, the 440 controller prepares to check if a user selects a new wash program after completing the control.

On the other hand, the control assembly 400 of the washing machine according to the present invention may not be limited to its structure and the operation procedure of the embodiment described above. That is, the steam selection part 430 can be one or more buttons that can be controlled by various manual operations such as selecting a start / end time of the steam supply, a quantity of steam supply, a time of steam supply Of course, it is preferred that the various factors can be selected in the event that the wash program selected by the user is one of the predetermined steam wash programs.

The procedure for controlling the washing machine according to the present invention may not be carried out solely by means of the procedure described above.

For example, a user selects a wash program and determines if the selected wash program is a wash program that uses steam. Therefore, in the case that the selected washing program can use steam, the steam selection part is activated to induce the selection. After that, in the event that a user has selected the steam selection part, steam washing can be carried out. That is, it is directly determined whether the selected washing program can use steam without comparing the selected washing program with a preset program to carry out steam washing. Of course, a standard program is preferably carried out even if a user selects the steam selection part, if it is determined that the selected washing program is not a program that uses steam.

Although the embodiments are described when implementing a washing machine, the present invention is not limited thereto. For example, the present invention can be applied to a dryer having a steam generator.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope of the invention. Therefore, it is intended that the present invention encompass the modifications and variations of the present invention with the proviso that they are within the scope of the appended claims and their equivalents.

The present invention provides a method for controlling a washing machine that has a steam generator and the procedure for the washing machine, in which a washing program using steam is operated only in the event that a selected washing program is one of washing programs that use steam. Therefore, the present invention has an industrial applicability, because various disadvantages resulting from steam generator failures can be avoided.
