Description
Technical field
The invention belongs to refrigerator technical field, be specifically related to a kind of refrigerator inside and outside air pressure balance device.
Background technology
The refrigeration appliance product that commercial in the market and domestic are sold, refrigerator, refrigerator-freezer, showcase and wine cabinet etc., in user's use procedure, need the device keeping internal and external pressure balance is installed on refrigerator, door body is easy to open, the current existing maintenance pressure balanced method of refrigerator indoor and outdoor, although indoor and outdoor pressure balance can be kept, but the problem that there is cold draining, namely the excessive entrance refrigerator of hot outdoor air is indoor, causing that refrigeration is not good, refrigerator can freeze again to design temperature, adds power consumption; Along with country's attention to energy saving policy, it is necessary to existing refrigerator technology is carried out detailed design, promotes energy-saving effect further.
Summary of the invention
The present invention is to solve weak point of the prior art, it is provided that a kind of simple in construction, with low cost, practical, can the refrigerator inside and outside air pressure balance device of quick balance chamber inner and outer air pressure when freezer door is closed.
For solving above-mentioned technical problem, the present invention adopts the following technical scheme that refrigerator inside and outside air pressure balance device, including air-flow interchange box and ventilative fixed bin, it is cavity structure inside air-flow interchange box and ventilative fixed bin, on the left of air-flow interchange box uncovered, air-flow interchange box right flank top is embedded with flase floor, and flase floor is provided with air inlet; On the left of ventilative fixed bin uncovered, the left side edge of ventilative fixed bin is sealedly connected on the left side edge of air-flow interchange box and blocks the uncovered position, left side of air-flow interchange box; On the left of ventilative fixed bin, uncovered position is connected to outer blocking cap, and outer blocking cap is uniformly provided with outer air-vent; Ventilative fixed bin right flank is provided with interior air-vent, it is filled with breathable rubber block in ventilative fixed bin, breathable rubber block left surface top is pressed on the right flank of outer blocking cap, breathable rubber block right flank is fixed with removable cover, removable cover right flank top is pressed in the right flank inwall of ventilative fixed bin, air-vent in removable cover closure.
Removable cover right lateral surface is vertically provided with water stream channel.
Adopt technique scheme, the method have the advantages that the present invention is by the air pressure unilaterally connected outside the air pressure in cabinet and cabinet, after the door body of refrigerator-freezer is opened and is closed again, extraneous air-flow enters in the cabinet of refrigerator-freezer, now the air pressure in cabinet is relatively higher than the air pressure outside cabinet, removable cover moves to refrigerator-freezer outside direction under the effect of inside and outside differential pressure and compresses breathable rubber block, the air inlet that the hot-air entering cabinet top first passes through on flase floor enters on the right side of the inner chamber of air-flow interchange box, then ventilative fixed bin is entered by interior air-vent, the breathable rubber block then passed through in ventilative fixed bin is discharged to outside cabinet by the outer air-vent on the outer blocking cap in left side, after the door body of refrigerator-freezer closes a period of time, in cabinet with cabinet outside flow communication, air pressure in cabinet is equal to the air pressure outside cabinet, air pressure inside and outside cabinet reaches balance, and removable cover again resets under the elastic reaction of breathable rubber block and returns to original state, and removable cover top is pressed in the right flank inwall of ventilative fixed bin, removable cover blocks interior air-vent again, thus blocking the exchange of air-flow inside and outside cabinet, it is therefore prevented that the leaking of cold air in cabinet, reach effect energy-conservation, insulation, the closing course of door body realizes cabinet inner and outer air pressure Fast-Balance, consequently facilitating open door body next time, the door body additionally closing refrigerator-freezer has in hot-air entrance cabinet simultaneously, the hot-air entered discharges a part by this device, balancing refrigerator-freezer inner and outer air pressure on the one hand, the hot-air discharged on the other hand need not be lowered to the temperature in refrigerator-freezer, thus decreasing the energy expenditure of refrigerator-freezer.
In sum, present configuration is simple, decrease cold air outflow, simultaneously quick balance chamber inner and outer air pressure, it is simple to next door opening action, has good market prospect, it is easy to promote.
