Definitions
- Refrigerating appliance in particular household freezer
- the invention relates to a refrigeration device, in particular a household freezer.
- DE 10 2006 040 381 A1 discloses a refrigerator with a body and a door hinged to the body, which delimit a heat-insulated interior.
- a pressure compensation valve is mounted in the wall of the body, which in the case of the negative pressure prevailing in the interior air from outside to inside and locks as soon as the pressure between the environment and the interior is balanced.
- the object of the invention is to provide a simplified refrigeration device, which creates conditions that the door can be opened at any time relatively easily.
- a refrigeration device in particular by a household freezer, comprising a body and a door, which define a heat-insulated interior with the door closed, wherein the door is closed in the direction of the interior directed inside of the door has a seal that established is to seal the interior at least as far as possible with the door closed, further comprising at least one arranged behind the seal recess in the inside of the door, which is adapted to let air under the seal.
- the refrigerator according to the invention which is in particular a freezer or the freezer compartment of a freezer-refrigeration combination, therefore includes, for example, the door pivotally mounted on the door, on the inside, ie possibly on the inner door, the seal for at least largely sealing the interior having.
- the inside is provided below the seal with the at least one recess.
- the recess is inventively designed so that air under the seal, in particular with the door closed in the interior of the refrigerator, ie in the interior, can flow.
- the recess is a defined leak, which has a pressure equalization after a resulting example by opening and subsequent closing negative pressure result.
- the inside of the door has a particular tightened on the inside groove, by means of which the seal is fixed to the inside of the door.
- the seal has e.g. a web which cooperates with the groove to be attached to the inside of the door.
- a gap is formed between the web and the recess.
- the recess of the refrigerator according to the invention is in one embodiment, in particular in the groove on the inside of the door in one piece, in particular mitstoffformt einstoffig, in particular mitanorgt.
- Such production e.g. By means of deep drawing, generally by means of tension forming, a precondition for a relatively simple and therefore cost-effective production method for the refrigeration device according to the invention results.
- the recess is arranged according to a preferred variant in the lower half of the door, in particular in the lower third of the door.
- the seal may comprise a section extending in particular horizontally in the lower region of the door, behind which the recess is arranged in particular centrally with respect to a longitudinal axis of the door.
- This embodiment has proven to be particularly favorable to prevent icing of the refrigerator.
- the seal is formed and / or extends over the recess, so that the seal and the recess form gaps which bound the side edges of the seal. This results in conditions that the air can flow under the seal from outside the refrigerator into the interior.
- the spatial extent of the recess transverse to the direction of the seal is smaller than the width of the seal.
- the recess may preferably be formed rectangular, whereby the recess can be relatively easily produced.
- the edge lengths may preferably be between 20mm and 35mm. Preferably, the edge lengths in the direction of the groove maximum 35mm, preferably 30mm. Right angles to the direction of the groove, the edge lengths are preferably a maximum of 30mm, preferably 26mm.
- the recess can preferably be formed by means of forming, in particular by deep drawing into the inside of the door, which can result in a relatively inexpensive production of the refrigerating appliance according to the invention.
- the recess is attracted to the inner door (inside of the door), for example, in the lower part of the seal groove, preferably in the middle of the door, for example.
- the air can flow under the seal in the interior of the refrigerator (interior), creating a targeted leak is created.
- the cross-section of the leak through the cut-out (recess) should be adapted to the current refrigeration device if necessary. If, for example, the recess is chosen to be too large, the refrigeration device according to the invention can be unintentionally dewed or frozen.
- the recess should also not be too wide, as it is then possible that when opening the door, the seal is pulled out of the groove.
- the refrigeration device according to the invention offers a cost-effective solution, since, for example, the additional pressure compensation valve conventional refrigerators can be omitted.
- the refrigerator according to the invention can be produced inexpensively because the additional recess only requires a small modification of existing production tools (low implementation costs). Also, there are prerequisites for a clean look.
- the recess according to the invention can be used in a relatively large number of refrigerators, in particular freezers. The production of the recess according to the invention in the inner door is also relatively reliable process.
- FIG. 2 is a plan view of a detail of the door of the household freezer
- Fig. 5 shows a part of the door without seal in a sectional view
- Fig. 6 shows a part of the door with seal in a sectional view.
- Fig. 1 shows a household freezer 1 in perspective view as an example of a refrigeration device.
- the household freezer 1 has a thermally insulated housing 2 with a rear wall, two side walls 3 and a lower and an upper wall 4, which define a freezer compartment 5.
- the household freezer 1 further comprises a hinged on the housing 2 heat-insulated door 6 for closing the freezer compartment 5.
- a plurality of drawers 7 are arranged one above the other, which can be at least partially pulled out of the freezer compartment 5 with open door 6, loaded with frozen food or to be able to remove from them stored and chilled frozen food.
- the household freezer 1 also has a non-illustrated, but well-known Käteniklauf for cooling the freezer compartment 5, which includes, for example, an evaporator, a compressor and a condenser.
- FIGS 2 to 6 show detailed views of the door 6 which, in the case of the present embodiment, comprises an inner skin (inner door) 8 e.g. made of plastic, an outer skin and arranged between the inner skin 8 and the outer skin insulation 9, for example made of foam.
- inner skin inner door
- outer skin e.g. made of plastic
- a circumferential seal 10 is provided on the inner skin 8 of the door 6, e.g. made of rubber.
- the seal 10 comprises adjoining sections 10a-10d, of which the sections 10a, 10b are vertical in the region of the vertical outer edges of the door 6, the section 10c horizontal in the region of the upper horizontal
- Outer edge and the portion 10d extend horizontally in the region of the lower horizontally extending outer edge 14.
- the inner skin 8 comprises a circumferentially extending groove 11 shown in more detail in FIGS. 2, 3, 5 and 6, in which a web 12 of the seal 10 is arranged.
- the inner skin 8 has been e.g. made of a plastic board by means of a forming process, in particular by means of a deep-drawing process, in the context of which the groove 11 has been formed by deep drawing into the inner skin 8.
- Fig. 2 shows the lower part of the door 6 and in particular the inner skin 8 in a plan view.
