Definitions
- the present invention relates to a refrigeration device such as a refrigerator or freezer with a pressure compensation valve, which serves to prevent the formation of a negative pressure in the interior of the refrigerator.
- Such door opening mechanisms necessarily include moving parts that are subjected to considerable forces during operation, such that wear and interference may occur.
- a pressure compensation valve which in the case of in the interior prevailing negative pressure air from the outside to the inside can and locks, as soon as the pressure between the environment and the interior is balanced, so that an uncontrolled entry of heat and moisture is excluded in the interior.
- the object of the invention is therefore to provide a refrigeration device with a pressure compensation valve between the interior and the environment, in which eliminates the risk of freezing of the pressure compensation valve or at least reduced.
- the object is achieved in that parallel to the pressure compensating valve, a passage permeable in two directions is formed in a wall of the housing whose conductance is smaller than that of the pressure compensating valve in its passage direction, but greater than the leakage value of the pressure compensating valve in its reverse direction.
- the passage allows low flow rate airflows caused by the periodic cooling and heating of the internal space due to the intermittent operation of a refrigerator to flow over the passage and not over the balance valve. It has surprisingly been found that the freezing of the pressure compensation valve usually does not go back to air flows, which flow respectively after closing the door by the pressure compensation valve, but that this much slower air flows are relevant.
- the temperature of the interior of the refrigerator is, even if the door remains closed, not exactly constant, but it varies periodically, and each cooling is associated with an influx of air into the interior, while in a warming air flows, ie it can be pictorial of a "inhalation” and "exhalation” of the refrigerator are spoken. While at a pressure equalization after door closing the air flows quickly through the pressure balance valve and moisture contained in it has little opportunity At the valve, the inflow is significantly slower, so that the incoming air already cools in the pressure balance valve and its moisture settles in it, with the result that the valve loses its mobility and clogs.
- the passage extends on a curved path through the wall.
- Such a curved passage may also be substantially longer than the thickness of the wall through which it passes, so that there is a large surface area available in the passage on which moisture from the inhaled air can be deposited. This reduces the likelihood that precipitated moisture will fill the cross-section of the passage and obstruct the flow of air.
- the passage extends in a substantially frost-free region of the housing. Since conventionally, a heater is often mounted on a front side of the body to prevent the door from freezing on the body, the passage is advantageously arranged in a region of the housing which is heated by this heater.
- the passage advantageously extends between the walls of the groove and an anchoring portion of the sealing profile engaging in the groove.
- Such a passage can be realized in a simple manner and without additional costs in the production of the already required groove.
- the passage can be conveniently created by each groove transverse to the longitudinal direction of the groove is recessed into side walls of the groove.
- a portion of the passage is guided in the longitudinal direction of the groove. This section can be created without any effort if it is limited on the one hand by a wall of the groove and on the other hand by the sealing profile.
- this rib is preferably locally interrupted to form the passage.
- At least one end of the passage is located at a corner of the door since the corners are generally the warmest areas of the door.
- Fig. 1 is a schematic perspective view of a refrigerator to which the present invention is applicable;
- FIG. 3 shows a lower corner of the inner wall of a refrigerator door according to the present invention
- FIG. 4 shows a section through the inner wall and the sealing profile anchored thereto along the plane designated IV in FIG. 2;
- FIG. 5 shows a section along the plane designated V of Fig. 2.
- 6 is a perspective view of a corner of the inner wall of a refrigerator door and a sealing profile received therein according to a second embodiment of the invention.
- FIG. 7 shows a section along the plane designated VII in FIG. 6.
- FIG. 1 is a schematic perspective view of a refrigerator with a body 1 and a door 2 hinged thereto, which enclose a cooled interior 3.
- a magnetic seal 4 is mounted in a conventional manner, which rests tightly in the closed position of the door 2 on a front side 5 of the body 1.
- the front side 5 is heated by a not visible in the figure, in the interior of the body 1 adjacent to the front 5 around the interior 3 extending refrigerant line, which is connected between the pressure outlet of a compressor and a condenser and, while the compressor operates, of warm Refrigerant is flowed through.
- FIG. 2 shows a perspective longitudinal section through the pressure compensation valve 7.
- FIG. 2 shows a perspective longitudinal section through the pressure compensation valve 7.
- the magnetic seal 4 is a flexible extrusion profile having a plurality of longitudinal chambers, one of which includes a magnetic tape 16 provided to to press the magnetic seal 4 firmly against the ferromagnetic front side 5 of the body 1.
- two projections 17, 18 are formed, one of which, 17, barbed.
- the projections 17, 18 engage in a groove 19 of the inner wall 10, which is divided by an extending in the longitudinal direction of the groove 19 rib 20 in an inner and an outer portion 21, 22.
- the barbs of the projection 17 are latched to undercuts of the inner portion 21.
- a in the width direction of the magnetic seal 4 extending, in the section 22 in bulging transverse wall 23 is held by the latch in a bending-loaded position in which it keeps the projection 18 pressed into the outer portion 22 of the groove 19.
- a thin, flexible wall portion 24 of the magnetic seal 4 is bent inwardly by an edge of the outer portion 22, so that the wall portion 24 is substantially close to this edge.
- a lip 25 is formed, which is pressed by the latching of the projection 17 tightly against an adjacent to the inner portion 21 shoulder 26 of the inner wall 10.
- the wall portion 24, the lip 25 and the barbs of the projection 17 form a plurality of sealing lines between the inner wall 10 and the magnetic seal 4th
- Fig. 4 which shows a section through the inner wall 10 and the magnetic seal 4 along the plane designated IV in Fig. 3, an outer contour 28 of this recess is visible.
- Fig. 5 shows a section along the inclined at 45 ° to the horizontal, in Fig. 3 designated V cutting plane. The section plane runs along the passage 15, and it can be seen that along this section plane neither the wall section 24 nor the barbs or the lip 25 touch the inner wall 10.
- FIG. 6 is like Fig. 2 is a perspective view of a corner of the inner wall 10, wherein the groove 19 of the inner wall 10 is shown equipped only on a part of its length with the magnetic seal 4 to one in the sections 21, 22 of the groove 19th from each other separating rib 20 formed cutout 30 can show.
- the cross sections of the groove 19 and the magnetic seal are the same as in the embodiment of Figs. 1 to 5.
- Fig. 5 section of Fig. 7 is in the sectional plane of this figure, the passage 15 through the Rib 20 interrupted.
- FIG. 5 is in the sectional plane of this figure, the passage 15 through the Rib 20 interrupted.
