Description
Technical field
The invention belongs to refrigerator technical field, and in particular to a kind of refrigerator inside and outside air pressure balance device.
Background technology
The refrigeration appliance product, refrigerator, refrigerator-freezer, showcase and wine cabinet etc. of commercial in the market and family expenses sale, with
, it is necessary to install the device for keeping internal and external pressure balance on refrigerator during the use of family so that door body is easy to open, existing at present
The pressure balanced method of holding refrigerator indoor and outdoor, although indoor and outdoor pressure balance can be kept, the problem of cold draining be present,
I.e. hot outdoor air excessively enters in refrigerator room, causes refrigeration bad, refrigerator can freeze to design temperature again, add
Power consumption；With attention of the country to energy saving policy, it is necessary to carry out detailed design to existing refrigerator technology, further lifting saves
Effect.
The content of the invention
The present invention is in order to solve weak point of the prior art, there is provided it is a kind of it is simple in construction, cost is cheap, practicality
By force, when freezer door is closed can quick balance chamber inner and outer air pressure refrigerator inside and outside air pressure balance device.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：Refrigerator inside and outside air pressure balance device, including
It is cavity structure inside air-flow interchange box and ventilative fixed bin, air-flow interchange box and ventilative fixed bin, on the left of air-flow interchange box
Opening, air-flow interchange box right flank top are embedded with flase floor, and flase floor is provided with air admission hole；It is open on the left of ventilative fixed bin,
The left side edge of ventilative fixed bin is sealedly connected on the left side edge of air-flow interchange box and blocks the left side of air-flow interchange box and opens
Oral area position；Open position is connected with outer blocking cap on the left of ventilative fixed bin, and outer air-vent is uniformly provided with outer blocking cap；Ventilative fixed bin
Right flank is provided with interior air-vent, is filled with breathable rubber block in ventilative fixed bin, breathable rubber block left surface top pressure is in outer blocking cap
Right flank on, breathable rubber block right flank is fixed with removable cover, and removable cover right flank top pressure is on the right side of ventilative fixed bin
Side inner walls, removable cover closure in air-vent.
Vertically water stream channel is provided with removable cover right lateral surface.
Above-mentioned technical proposal is used, the invention has the advantages that：The present invention is by outside the air pressure and cabinet in cabinet
Air pressure unilaterally connected, after the door body of refrigerator-freezer, which is opened, closes again, extraneous air-flow enters in the cabinet of refrigerator-freezer, now cabinet
Internal air pressure is relatively higher than the air pressure outside cabinet, and removable cover moves simultaneously in the presence of inside and outside differential pressure to refrigerator-freezer outside direction
Breathable rubber block is compressed, is entered first by the air admission hole on flase floor in air-flow interchange box into the hot-air at the top of cabinet
On the right side of chamber, ventilative fixed bin is then entered by interior air-vent, then passes through the breathable rubber block in ventilative fixed bin by left side
Outer air-vent on outer blocking cap is discharged to outside cabinet；When refrigerator-freezer door body close a period of time after, by cabinet with outside cabinet
Flow communication, the air pressure in cabinet is equal to the air pressure outside cabinet, and the air pressure inside and outside cabinet reaches balance, and removable cover is being breathed freely
Resetted again under the elastic reaction of block rubber and return to original state, and by removable cover top pressure in the right flank of ventilative fixed bin
Wall, removable cover block interior air-vent again, so as to block the exchange of air-flow inside and outside cabinet, it is therefore prevented that cold air is outer in cabinet
Let out, reach energy-conservation, the effect of insulation；The closing course of door body realizes cabinet inner and outer air pressure Fast-Balance, consequently facilitating next time beats
Opening door body；The door body of refrigerator-freezer is closed in addition while has hot-air and is entered in cabinet, and the hot-air of entrance is outside by the present apparatus
A discharge part, refrigerator-freezer inner and outer air pressure is on the one hand balanced, on the other hand the hot-air of discharge need not be lowered in refrigerator-freezer
Temperature, so as to reduce the energy expenditure of refrigerator-freezer.
In summary, the present invention is simple in construction, reduces cold air outflow while quick balance chamber inner and outer air pressure, under being easy to
Secondary door opening action, there are good market prospects, it is easy to spread.
