Cold room
Abstract
The chamber has a ventilator (13) located inside the chamber (1) above the door opening (12), along the whole width of the door opening. It consists of a ventilating fan or blower (14) which takes air from the room and blows it vertically down as cold air in the form of an air curtain (15). The air curtain covers the entire height and width of the door opening. The blower is actuated by a door switch when the door is opened. The switch turns on the blower as the door is unlocked, hence the air curtain is fully formed before the door is actually opened.

0001The invention relates to a cold chamber according to the preamble of claim. 1
0002Such cold chambers for storage of products in frozen condition, in particular for the storage of dough or baked goods, are known per se. A disadvantage of known refrigerating chambers, that the introduction and removal of Products or upon entering the chamber through the open door warm outside air into the chamber interior passes. To overcome this drawback has been proposed, on the outside of the chamber through the door opening means provide, with the then also on the outer side of the opened door is a Doorway of overlapping fog is produced from cold air there. However, it has shown that this measure is not effective, it on the contrary in spite of the air curtain particularly cold areas, for example on a ceiling for icing comes.
0003Object of the invention is to show a cold chamber that this disadvantage avoids. To achieve this object is a cold chamber in accordance with the Claim 1 run.
0004In the invention, the means for generating the cold air curtain in the interior of Chamber provided and also the cold air curtain is inside the chamber educated. Surprisingly, this measure is an icing avoided. This is due to a underlying the invention Knowledge apparently that turning on the cold air curtain before opening the door is carried out and with this veil at power then no warm outside air into the chamber interior is pressed and also between the air curtain the further inside of the chamber a cold zone is present exclusively.
0005Further developments of the invention are the subject of the dependent claims. The invention is explained below with reference to the figures of an embodiment in more detail. It show:<sl><li>FIG. 1 is a simplified representation in cross section, a chamber for frozen Storage of bakery products according to the invention;</li><li>FIG. 2 is an end view of the chamber of Figure 1, with the door closed.</li></sl>
0006In the figures, 1 generally designates a chamber whose interior space 2 for frozen storage of products (at a temperature of, for example - 18 ° C), namely in the illustrated embodiment specifically for frozen Storage of bakery serves. The chamber 1 is quarderförmig in its outer form run, with thermally insulated side walls 3 and end walls 4 and 5 and with thermally insulated floor 6 and thermally insulated ceiling 7. In Interior 2 is an otherwise not shown on the ceiling 7 of the evaporator 8 arranged cold machine, along with a fan 9. Below the Evaporator 8 is a reproduced in the figure 1 by broken lines False ceiling 10 which is for example made of metal profiles and an air passage allows. At the front front 5 a is through a Door wing 11 thermally sealable door opening 12 is provided, via which the Introducing and removing the products in stock or out of the interior space 2 takes place. With 13 fan means indicated that the inside Chamber 1 above the door opening 12 over the entire width of the door opening extends. The blower unit 13 is in this case in the space above the False ceiling 10 and includes among others a fan or blower 14, which air draws from this room and this cold air in the form of an air curtain 15 perpendicularly blows down, which also air curtain over the entire height of 15 Door opening 12 and extends over a width equal to or preferably slightly greater than the width of the door opening 12 by a door switch, the fan unit 13 is always turned on when the door 11 is opened. is preferred This door switch configured such that it already when unlocking the Türflugelverschlußes 16, the fan 13 turns, so that the air curtain 15 full formed before the door leaf is 11 actually opened. through this Air curtain 15 is the penetration of external warm air during the introduction and Application of goods in and out of the chamber 1, or when entering this Chamber 1 prevents, in particular is also prevents outside air Moisture is carried off into the interior 2, which then undesirably Way on particularly cold areas, namely on the false ceiling 10 as ice reflected.
0007It will be appreciated that the fan assembly 13 at the bottom directly on the upper boundary of the door opening 12 at least one, for example, a slit trained and extending over the entire width of the door opening 12 comprises air outlet opening which is formed to the ceiling 10 under the intermediate Interior of the chamber 1 is open.
