Utility model content
The purpose of this utility model is:, the problem that be difficult for open the door large for current refrigerator refrigerating chamber inside and outside differential pressure, provide a kind of can balance refrigerator freezing indoor and outdoor pressure, the device that makes refrigerator doors open easily and don't can cause cold air to leak, to overcome the deficiencies in the prior art.
Another object of the present utility model is to provide the refrigerator of the device of the inside and outside pressure of the above-mentioned balance refrigerator of application.
The technical scheme in the invention for solving the technical problem is: the device of the inside and outside pressure of balance refrigerator, the lower location-plate of door inner bag, door and the door foaming layer that comprise refrigerator door, on refrigerator doors inner bag, be provided with balance pipe, on the position of the corresponding balance pipe of the alveolar layer side of inner bag, be provided with pressure-reducing valve Connection Block, under refrigerator doors, on location-plate, be provided with pressure-reducing valve holder, pressure-reducing valve holder is provided with the pore communicating with the external world, on pore, be provided with adjustment cap, between pressure-reducing valve holder and pressure-reducing valve Connection Block, be connected with pressure-equalizing passageway.
Described pressure-equalizing passageway comprises pressure-reducing valve tube connector and pressure-reducing valve tube channel, and pressure-reducing valve tube connector connects pressure-reducing valve holder, is provided with pressure-reducing valve tube channel on pressure-reducing valve Connection Block, pressure-reducing valve tube connector and the socket of pressure-reducing valve tube channel.
The end of described pressure-reducing valve tube connector is provided with mounting groove, on the pedestal of described mounting groove interlocking location-plate under door.
Between described pressure-reducing valve Connection Block and door inner bag, be provided with sealing sponge.
A refrigerator is provided with the device of pressure inside and outside above-mentioned balance refrigerator in refrigerator door.
The beneficial effects of the utility model are:
The device of the inside and outside pressure of balance refrigerator of the present utility model is reasonable in design, by set up interface channel between door inner bag and bottom end cover, with at bottom end cover, export out the adjustment cap of setting up, freezer compartment of refrigerator air pressure inside is communicated with ambient pressure, refrigerating chamber pressure and ambient pressure are consistent, can cause the difficulty of opening refrigerator doors, and because there is the adjusting of adjustment cap, in equilibrium pressure, can not cause again the cold air in refrigerating chamber to leak.
Accompanying drawing explanation
Fig. 1 is the structural representation of the inside and outside pressure device of the utility model balance refrigerator.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The utility model provides the device of the inside and outside pressure of a kind of balance refrigerator, be arranged in the door body of freezer compartment of refrigerator, refrigerator door comprises an inner bag, the lower location-plate of door and door foaming layer, as shown in Figure 1, on refrigerator doors inner bag 1, be provided with balance pipe 11, on the position of the corresponding balance pipe of the alveolar layer side of door inner bag 1, be provided with pressure-reducing valve Connection Block 7, under refrigerator doors, on location-plate 2, be provided with pressure-reducing valve holder 3, pressure-reducing valve holder 3 is provided with the pore 10 communicating with the external world, on pore 10, be provided with adjustment cap 4, between pressure-reducing valve holder 3 and pressure-reducing valve Connection Block 7, be connected with pressure-equalizing passageway.
This pressure-equalizing passageway comprises pressure-reducing valve tube connector 5 and pressure-reducing valve tube channel 6, and pressure-reducing valve tube connector 5 connects pressure-reducing valve holder 3, is provided with pressure-reducing valve tube channel 6 on pressure-reducing valve Connection Block 7, pressure-reducing valve tube connector 5 and 6 sockets of pressure-reducing valve tube channel.The end of pressure-reducing valve tube connector 5 is provided with mounting groove, on the pedestal 9 of mounting groove interlocking location-plate 2 under door.Between pressure-reducing valve Connection Block 7 and door inner bag, be provided with PE sealing sponge 8, guarantee the sealing of pressure-reducing valve Connection Block 7 and door inner bag.
The temperature indoor due to refrigerator freezing is lower, therefore, when refrigerating chamber is when closing the door state for a long time, air pressure in it will be less than the air pressure of refrigerator external environment, make freezer compartment of refrigerator in negative pressure state, on freezer compartment of refrigerator door body, be provided with inside and outside balance refrigerator of the present utility model after pressure device, when the air pressure of refrigerating chamber is during lower than environmental pressure, air enters in pressure-equalizing passageway from the gap of pressure-reducing valve holder 3 pores and adjustment cap 4, and enter refrigerating chamber inner chamber by the balance pipe 11 on refrigerator doors inner bag, air in refrigerating chamber is supplemented, realized the balance of refrigerating chamber inner and outer air pressure.
