Description

A kind of refrigerator

Technical field

The present invention relates to a kind of refrigerator, particularly relate to the refrigerator of a kind of high duty, low power consumption.

Background technology

When existing refrigerator is put in the family, generally leaning against about wall at least 5 ~ 10cm, making things convenient for the heat dissipation ventilation of refrigerator refrigeration machine (compressor and condenser), be beneficial to the operate as normal of refrigerator, helping energy saving simultaneously.Built-in refrigerator also is so, needs distance wall at least 5 ~ 10cm on every side, so that heat dissipation ventilation.Refrigeration machine is arranged in the Machine Room of bottom, refrigerator behind usually; As shown in Figure 1; Be disposed with fan 11, condenser 10, compressor 9 in the Machine Room of refrigerator; Be provided with chassis 5 between Machine Room and the ground, between Machine Room and metope, be provided with ratguard, because here in order to see the structure of refrigerator mechanical chamber inside, so do not embody ratguard.5 fan 11 1 sides of closing on are provided with ventilating opening a (1-2) on the chassis, are provided with ventilating opening b (2-2) in a side of closing on compressor 9.During refrigerator work,, cool exterior air is sucked from the ventilating opening a (1-2) near fan 11 1 sides through motor-driven fan; Pass through mechanical chamber condenser, compressor successively, carry out that the ventilating opening b (2-2) from opposite side discharges after the heat exchange, because the close on chassis 5 and ground; The refrigerator back is very near from metope; So run into ground or wall from the hot-air that ventilating opening b (2-2) discharges, form gas backstreaming, a part of gas gets in the Machine Room of refrigerator from ventilating opening a (1-2) again.So just make the gas temperature in the Machine Room raise, not only influenced radiating effect, reduced the refrigeration performance of refrigerator, increased power consumption, also shortened the service life of refrigerator simultaneously.

Summary of the invention

To the unreasonable hot air reflow that causes of present refrigerator design, influence the refrigerator refrigerating efficiency, increase the problem of power consumption; The invention provides a kind of refrigerator; All set up thermal insulation barriers at its base plate and ratguard, can effectively stop after discharge from a side ventilating opening through the hot-air after the heat exchange Machine Room, refluxed again and get into the Machine Room again; Reach raising radiating effect, economize on electricity, prolonged the refrigerator effect in service life.

In order to reach the foregoing invention purpose, we have adopted following technical scheme:

A kind of refrigerator; Comprise ratguard; Said ratguard closes on fan one side and offers ventilating opening m, and an other side of corresponding ratguard also offers ventilating opening n therewith, and the outside cold air in Machine Room is inhaled into the Machine Room via ventilating opening m; And be blown from ventilating opening n; Between said ventilating opening m and n, be vertically arranged with thermal insulation barriers, said thermal insulation barriers one end is fixed in the refrigerator ratguard, and an other free end is divided into two independently air backflow spaces to body of wall or barricade extension until the spatial with ratguard and metope formation.Owing to be provided with thermal insulation barriers at ratguard; And this thermal insulation barriers effectively comes ventilating opening m (air inlet) with ventilating opening n (exhaust outlet) partition; So the gas of discharging from ventilating opening n can only form in the space of thermal insulation barriers one side and flow, and can not get into the Machine Room via ventilating opening m once more, has reached and has blocked the radiating effect that hot air reflow has been strengthened condenser and compressor; Improved the refrigerating efficiency of refrigerator, reached economize on electricity, prolonged the refrigerator purpose in service life.

Based on same invention thinking, for the air backflow space of refrigerator and ground formation, we have also taked relative measures.A kind of refrigerator; Comprise the chassis, Machine Room; Chassis, said Machine Room is closed on fan one side and is offered ventilating opening a, and an other side on corresponding chassis, Machine Room also offers ventilating opening b therewith, and the outside cold air in Machine Room is inhaled into the Machine Room via ventilating opening a; And be blown from ventilating opening b; Between said ventilating opening a and b, be vertically arranged with thermal insulation barriers, said thermal insulation barriers one end is fixed in the chassis, Machine Room, and an other free end extends until the outside spatial that forms with ground in chassis, Machine Room is divided into two independently air backflow spaces earthward.Owing on the chassis, be provided with thermal insulation barriers; Come thereby effectively ventilating opening a (air inlet) is cut off with ventilating opening b (exhaust outlet), the hot-air that one side is discharged from the refrigerator chassis can only flow in the space of thermal insulation barriers one side, and can not get into the Machine Room via ventilating opening b once more; Thereby can not make the temperature of air of Machine Room raise; Strengthened the radiating effect of condenser and compressor, improved the refrigerating efficiency of refrigerator, reached economize on electricity, prolonged the refrigerator purpose in service life.

As the improvement of foregoing invention, the thermal insulation barriers that we will only be arranged on the chassis extends longitudinally to Noise reducing curtain, and refrigerator bottom and the spatial that ground forms are divided into two independently air backflow spaces.After taking this technical scheme; It is isolated that the hot air reflow that ventilating opening b bottom refrigerator discharges not only receives the chassis thermal insulation barriers; And the hot-air of its a spot of inflow bottom parts be extended again to the thermal insulation barriers of Noise reducing curtain isolated, thereby make isolated better effects if.

Certainly, in order further to improve the technique effect of thermal insulation barriers, said refrigerator ratguard simultaneously is provided with thermal insulation barriers.That is to say simultaneously and on chassis, base plate, ratguard, thermal insulation barriers is set with ratguard or while on the chassis.Because after hot-air sheds from each exhaust outlet is divergent shape,, reach better isolated effect so such thermal insulation barriers setting can be blocked the backflow of hot-air at ground and metope place simultaneously.

As other a kind of improvement, the free end top of said thermal insulation barriers is an elastic bag.Because elastic bag is the part of being longer than refrigerator and body of wall or ground, so when refrigerator during near body of wall or ground, elastic bag is squeezed, and is adjacent to body of wall or ground, thereby better guarantees the sealing of thermal insulation barriers under the different operating positions.

At last, the invention discloses said thermal insulation barriers is integrated.Thereby make the total seal better, more convenient when being assembled to refrigerator.

In a word; After the technical scheme that the employing invention provides, compared with prior art, the present invention is flowed the air between air inlet and the exhaust outlet and is cut off; Air is independently flowing in the space separately; Keep the lower temperature of air inlet air, thereby improved the refrigerating efficiency of refrigerator, and then reduced the power consumption of refrigerator greatly.
