Definitions

  • the present invention relates to a refrigerator with a refrigerator door, which comprises an inserted ventilation valve for ventilating a refrigeration compartment when the refrigerator door is opened
  • the disclosure DE 10 2008 021 375 A1 shows a refrigerator with a pressure compensation valve.
  • the disclosure EP 2 090 854 A2 shows a refrigerator.
  • the US 3,027,735 A shows a refrigerator with an air passage, which is arranged on a lower portion of a door of the refrigerator, wherein a rubber sheet valve is arranged by means of a plate over an opening of the air passage on a bottom of the door.
  • the object is achieved by a refrigeration device with a refrigeration device door, which comprises an inserted ventilation valve for ventilating a refrigeration compartment when the refrigeration device door is opened, in which the ventilation valve has a Base plate with an air opening, an elastic membrane for covering the air opening and a cover element placed on the elastic membrane for fastening the elastic membrane to the base plate.
  • the ventilation valve can be installed inconspicuously in the refrigerator door with little installation space and can be produced with little technical effort.
  • a refrigeration device is understood in particular to mean a household refrigeration device, that is to say a refrigeration device that is used for household management in households or in the catering sector, and in particular serves to store food and / or beverages at certain temperatures, such as a refrigerator, a freezer, a fridge-freezer combination, a freezer or a wine fridge.
  • the ventilation valve comprises a film hinge for rotatably connecting the base plate and the cover element.
  • the membrane comprises at least one opening for aligning the membrane on the base plate.
  • the cover element comprises a protruding lip for pressing the membrane onto the base plate.
  • the base plate comprises a receptacle for a door seal of the refrigeration device door.
  • the refrigerator door comprises a deep-drawn pocket for inserting the ventilation valve.
  • the ventilation valve can be integrated into the refrigerator door and the membrane can be held in the closed position by gravity.
  • the pocket is arranged on an underside of the refrigerator door. This has the technical advantage, for example, that when the refrigerator door is opened, air is led into the refrigerator compartment from below.
  • the pocket forms an airway around a door seal. This has the technical advantage, for example, that the inflowing air can be introduced from the edge of the refrigerator door.
  • the pocket engages around the base plate in a form-fitting manner. This has the technical advantage, for example, that an undesired outflow of air between the ventilation valve and the refrigerator door is prevented.
  • the inner side of the elastic membrane projects beyond the base plate.
  • the base plate comprises two projecting pins for attaching the cover element. This achieves the technical advantage, for example, that the membrane is reliably held by the attached cover element.
  • the cover element comprises a latching means for latching into the projecting pin.
  • the base plate comprises laterally molded-on ribs for sealing the ventilation valve. This also achieves the technical advantage, for example, that a lateral gap can be sealed.
  • the air opening has a rectangular cross section. This has the technical advantage, for example, that a large amount of air can quickly pass through the ventilation valve.
  • the base plate and / or the cover element is a molded plastic part. This achieves the technical advantage, for example, that the ventilation valve can be manufactured quickly and efficiently.
  • Fig. 1 shows a refrigerator representative of a refrigerator 100 with an upper refrigerator door and a lower refrigerator door.
  • the refrigerator is used, for example, to cool food and comprises a refrigerant circuit with an evaporator, a compressor, a condenser and a throttle element.
  • the evaporator is a heat exchanger in which, after expansion, the liquid refrigerant is evaporated by absorbing heat from the medium to be cooled, ie the air inside the refrigerator.
  • the compressor is a mechanically operated component that sucks refrigerant vapor from the evaporator and discharges it to the condenser at a higher pressure.
  • the condenser is a heat exchanger in which, after compression, the evaporated refrigerant by giving off heat to an external cooling medium, i.e. the ambient air is liquefied.
  • the throttling device is a device for the constant reduction of pressure by narrowing the cross-section.
  • the refrigerant is a fluid used for heat transfer in the cryogenic system that absorbs heat at low temperatures and low pressures of the fluid and releases heat at higher temperatures and pressures of the fluid, usually including changes in the state of the fluid.
  • the refrigeration device 100 comprises an upper and a lower refrigeration device door 103, each of which closes a refrigeration compartment in the interior of the refrigeration device 100 and can be opened by a user.
  • Fig. 2 shows a view of a disassembled ventilation valve 101.
  • the ventilation valve 101 comprises a base plate 105 and an elastic membrane 109.
  • a rectangular air opening 107 is formed in the base plate 105.
  • the membrane 109 lies on the top of the base plate 105.
  • the membrane 109 is raised by the negative pressure, so that air can flow through the released air opening 107.
  • a negative pressure can be reduced in the interior of the refrigeration compartment, which would make it difficult to open the refrigerator door 103.
  • the membrane 109 is, for example, a rubber membrane with a thickness of 0.35 mm.
  • the base plate 105 comprises two cylindrical pins 125 which protrude upwards from the base plate 105.
  • the membrane 109 comprises two openings 113 at corresponding positions, which are placed on the pins 125 when the ventilation valve 101 is assembled.
  • a cover element 111 is fastened by means of a film hinge 131. Since a film hinge 131 is used, the base plate 105 can be produced together with the cover element 111 in a single injection molded part with an injection molding tool. The film hinge 131 is in an unbent state and the cover element 111 is open.
  • Latching means 127 are formed in the cover element 111, which snap into place on the pin 125 when the cover element 111 is closed. By folding over the cover element 111, which is connected directly to the base plate 105 by means of the film hinge 131, the membrane 109 is fixed after the latching means 127 has snapped into place.
  • a protruding lip 115 is formed on the rear side of the cover element 111.
  • a receptacle 117 with a U-shaped cross section for a circumferential door seal.
  • the door seal of the refrigerator door 103 is inserted into the receptacle 117. This allows the ventilation valve 101 to be fixed behind the door seal.
  • the door seal is formed, for example, by a circumferential rubber seal that includes a magnetic element.
  • Fig. 3 shows a view of the assembled ventilation valve 101.
  • the cover element 111 is engaged by means of the latching means 127 on the pin 125 of the base plate 105 and is in the closed state.
  • the membrane 109 is thereby clamped and fixed between the base plate 105 and a cover element 111.
  • the lip 115 of the cover element 111 rests on the membrane 109 and serves to smooth the membrane 109.
  • the lip 115 on the cover element 111 presses the membrane 109 downward in front of the air opening 107. This prevents warping and ensures an optimal seal. This ensures that the ventilation valve 101 seals well in the closed state.
  • the film hinge 113 is in the bent state.
  • Fig. 4 shows a view of a refrigerator door 103 with a ventilation valve 101 inserted.
  • the inside of the refrigerator door 103 is formed from a drawn circuit board.
  • a deep-drawn pocket 121 is formed on the underside of the refrigerator door 103 and defines a recess in the refrigerator door 103.
  • the assembly of the ventilation valve 101 is pushed into the provided pocket 121 in the inside of the refrigerator door 103 and secured against falling out by the surrounding door seal 119. It is not necessary to snap the ventilation valve 101 into the pocket 121 on the inside of the refrigerator door 103, so that simple installation can be realized and the ventilation valve 101 only has to be inserted into the pocket 121.
  • the pocket 121 forms an air path 123 which leads around the door seal 119 in the inside of the refrigerator door 103.
  • the ventilation valve 101 is inserted in the air path 121 and blocks an air flow from the interior of the refrigeration compartment. In the opposite direction, the ventilation valve 101 allows the air flow into the interior of the refrigeration compartment, so that a negative pressure in the refrigeration compartment can be prevented.
  • the elastic membrane 109 With an air flow inside the cold compartment, the elastic membrane 109 is raised from the base plate 105. The entering air flows through the resulting gap between membrane 109 and base plate 105. This reduces the door opening forces.
  • Fig. 5 shows a cross-sectional view of a refrigerator door 103 with a ventilation valve 101 inserted.
  • the dashed arrows show the air path when the refrigerator door 103 is opened.
  • the air enters the pocket 121 on the underside of the refrigerator door 103 below the door seal 119 and is passed through the interior of the refrigerator door 103 Ventilation valve 101 performed.
  • the air exits the inside of the refrigerator door 103 above the door seal 119.
  • the cover element 111 presses the membrane 109 against the air opening 107, so that the air flow can only pass the pocket 121 in one direction.
  • the door seal 119 is located in the U-shaped receptacle 117 in cross section and holds the ventilation valve 101 in the pocket 121.
  • the base plate 105 of the ventilation valve 101 is encompassed in the pocket 121 laterally and behind by the inner door. This results in a sealing of the base plate 105 against the inner door. Therefore, no undercuts in the refrigerator door 105 are required to lock the ventilation valve 101. Since no latching hooks are required on the base plate 105 to fasten the ventilation valve 101 to the refrigerator door 103, a simple injection molding tool without a slide can be used to manufacture the ventilation valve 101.
  • Fig. 6 shows an enlarged view of the ventilation valve 101 inserted into the refrigerator door 103 without an inserted door seal 119. If the membrane 109 protrudes laterally beyond the base plate 105, this can additionally be used as a seal against the inner door. In this case, the membrane 109 seals a lateral gap on the ventilation valve 101.
  • Fig. 7 shows a further view of the ventilation valve 101 inserted into the refrigerator door 103.
  • the base plate 105 can be provided with laterally projecting, elastic ribs 129, which are arranged laterally resiliently relative to the base plate 105.
  • the ribs 129 are injection molded onto the base plate 105, for example.
  • the thin, flexible ribs 129 on the base plate 105 provide a lateral seal against the inner door. This has the advantage that lateral manufacturing tolerances of the pocket 121 can be compensated for.
  • the base plate 105 and the cover element 111 are a molded plastic part.
  • the ventilation valve 101 can be used universally in various device series. An undercut on the inside of the refrigerator door 103 is not required to insert the ventilation valve 101, so that the inside door can be produced using a simple drawing tool.
  • the ventilation valve 101 can be used to form a small, easy-to-integrate component which can be inconspicuously integrated into the design of the refrigeration device 100.
  • the ventilation valve 101 forms a thin assembly, so that the installation situation in the refrigerator door 103 improves.
