Problems solved by technology

However, when the heater is driven for defrosting, cold air delivery must be stopped for a period of time
In addition, since the heater will generate heat when defrosting, the temperature inside the refrigerator will rise, resulting in an increase in the refrigeration load when the refrigeration is restarted, reducing the refrigeration efficiency.

Embodiment approach 1

[0029] Such as Figure 3a As shown, in the independent refrigeration type refrigerator of the present embodiment, the freezer compartment 1 and the freezer compartment 2 are separated from each other with a partition 3, so that the cold air passage (A) circulating in the freezer compartment 1 and the cold air passage (A) circulating in the freezer compartment 2 The cold air paths (B) are separated from each other. The freezing compartment 1 and the refrigerating compartment 2 share an evaporator 30 for heat exchange. When the refrigerator is running, the compressor 21 sends the low-temperature / low-pressure gaseous refrigerant to the condenser 23 after heating / boosting; then, the low-temperature / high-pressure liquid refrigerant produced by the condenser 23 is sent to the expansion unit through a small-diameter pipeline. Valve 25; the low-pressure / low-temperature liquid refrigerant generated by the expansion valve 25 is sent to the evaporator 30, where it evaporates in a low-pr...

Embodiment approach 2

[0042] Such as Figure 3b As shown, the independent refrigeration type refrigerator of the present embodiment includes two evaporators 31 and 32, and the evaporators 31 and 32 are connected in series, respectively located in the cold air passage (A) of the freezer compartment and the cold air passage (A) of the refrigerator compartment ( B) inside.

[0043] Such as Figure 4bAs shown, in the independent refrigeration type refrigerator of the present embodiment, two evaporators 31 and 32 connected in series are respectively arranged on the top of the cold air channel 100 of the freezing room and the cold air channel 200 of the refrigerating room, respectively in the freezing room 1 and the refrigerating room Heat exchange is performed in chamber 2. An advantage of this embodiment is that excessive cooling of the refrigerator compartment can be prevented.

[0044] Other structures of this embodiment are the same as those of Embodiment 1, and will not be repeated here.

Abstract

An electric refrigerator with individual refrigeration for freezing chamber and cold storage chamber is composed of casing, freezing chamber, cold storage chamber, compressor, condenser, expansion valve, fan and evaporator. Its features are that said freezing chamber and cold storage chamber have individual cold air channels, one for each chamber, and a single-evaporator or serially connected twoevaporators are used for both chambers. Its advantage is high refrigerating efficiency.

Description

technical field [0001] The invention relates to a refrigeration device, in particular to a refrigerator. Background technique [0002] Refrigerator is a kind of necessities of life, and it can freeze or keep fresh the food stored in the refrigerator for a period of time. The working principle of an ordinary refrigerator is to generate low temperature inside the refrigerator through repeated cycles of compression, condensation, expansion, and evaporation of the refrigerant. [0003] The structure of an ordinary refrigerator mainly includes: a compressor, a condenser, an expansion tube and an evaporator. The function of the compressor is to compress the refrigerant from a low-temperature / low-pressure gaseous state to a high-temperature / high-pressure gaseous state; the function of the condenser is to condense the high-temperature / high-pressure gaseous refrigerant output from the compressor into a low-temperature liquid state; the function of the expansion tube is to make the c...
