The dehumidification device of refrigerator
Technical field
The present invention relates to refrigerating fields, more specifically, it relates to a kind of dehumidification device of refrigerator.
Background technique
Refrigerator, main function are to guarantee that the fresh therefore fresh-keeping effect of chilled food is the choosing important as one
Purchase foundation.According to scientific analysis, to keep the fresh of food, on the one hand needing cabinet interior to have, constant temperature is strong " freezing power ",
On the other hand, the air cleaning in the cabinet that needs that Keep cool is fresh.
The principle of refrigerator is the low-pressure steam of refrigeration system inner refrigerant by compressor sucking and boil down to high steam
Heel row passes through condenser, the heat of refrigerant releasing is taken away by condenser, condenses high pressure refrigerant vapor to condenser
For highly pressurised liquid.Highly pressurised liquid sprays into the refrigerating evaporator of interior of the cabinet after filter, throttle mechanism, and corresponding low
Pressure evaporation, draws the intracorporal heat of cabinet, achievees the purpose that refrigerator cabinet body reduces temperature.
However the article stored in refrigerator has moisture, also has moisture during Simultaneous Switching refrigerator and enters
Interior of the cabinet, and the moisture entered in refrigerator liquefies can condense to form water droplet in the inner wall of cabinet body to the cold, and steamed in refrigeration
Sending out device and nearby condensing is that water droplet is easy to build-up ice, the final effect for influencing refrigeration;In the prior art to cabinet interior into
Row dehumidifying, it will usually using first heating, reheat air progress refrigeration liquefying and complete dehumidifying, since this method needs heating wire
It is heated, this undoubtedly will increase additional power consumption.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of dehumidification device of refrigerator, utilize
Condenser is heated to the intracorporal air of cabinet, to reduce energy consumption.
To achieve the above object, the present invention provides the following technical scheme that a kind of dehumidification device of refrigerator, including refrigeration

Form the air of high temperature drying;The air of high temperature drying can be reentered with circulation line 31 to cabinet body 1, be made in cabinet body 1
The small-scale rising of the temperature of air, and because air is more dry, the moisture in cabinet body 1 can be evaporated in air,
It is removed in circulation next time, so that the humidity in cabinet body 1 is reduced with the continuous circulation of air exchange system 3, reaches and remove
Wet effect.
Be provided with loop dehumidification 43 on dehumidifier 4, loop dehumidification 43 connects dehumidifier 4 and cabinet body 1, dehumidifier 4 with it is cold
Circulation line 31 between condenser 23 is provided with switching valve F1, and switching valve F2 is provided on loop dehumidification 43, mutual by F1, F2
Cooperation, realize the dehumidifying of different mode;
(1) when switching valve F1 is closed, and switching valve F2 is opened, air in cabinet body 1 is passed through by circulation line 31 to removing
In wet device 4, the vapor in air is made to liquefy under the action of dehumidify evaporimeter 5, realize dehumidifying, air after dehumidifying is along removing
Wet circuit 43 is flow back into cabinet body 1, is made air mutual circulation in dehumidifier 4 and cabinet body 1, is completed dehumidifying, this mode is applicable in
In slight dehumidifying.
(2) when switching valve F1, which opens switching valve F2, to close, air in cabinet body 1 can along circulation line 31 into
Enter into condenser 23, complete the heating of air, the air of dry high temperature is conveyed into cabinet body 1;This mode can carry out height
The dehumidifying of effect.
Embodiment two:
As shown in Fig. 2, the difference between this embodiment and the first embodiment lies in, circulation line 31 comes out to enter and remove from cabinet body 1
Two branches are divided into after wet device 4, respectively heating branch 33 and circulation branch road 34, heating branch 33 can pass through condenser 23
It is heated, and is returned directly to cabinet body 1 after recycling, switching valve F1 is provided on heating branch 33, in circulation branch road 34
The dehumidifying of different mode is realized by the mutual cooperation of F1, F2 provided with switching valve F2.
(1) when switching valve F1 is closed, and switching valve F2 is opened, air in cabinet body 1 is passed through by circulation line 31 to removing
In wet device 4, the vapor in air is made to liquefy under the action of dehumidify evaporimeter 5, realize dehumidifying, air after dehumidifying is along following
31 tunnel of endless tube road is flow back into cabinet body 1, is made air mutual circulation in dehumidifier 4 and cabinet body 1, is completed dehumidifying, this mode is suitable
For slight dehumidifying;
(2) when switching valve F1, which opens switching valve F2, to close, air in cabinet body 1 can along circulation line 31 into
