Embodiment 1

[0052] Such as Figure 2-11 Shown, a kind of refrigerator comprises:

[0053] A box body, the box body has a low-temperature storage space;

[0054] A compressor compartment, the compressor compartment is located outside the box, and the compressor compartment is provided with a compressor 9, a condenser 1 and a first water receiving tray 2 located on the lower side of the condenser 1;

[0055] The box body is provided with a drainage system 7 communicating with the compressor compartment, and the drainage system 7 is communicating with the first water receiving tray 2 through a drainage pipe. The refrigerator also includes:

[0056] The second water receiving tray 52 arranged on the upper side of the condenser 1, the drainage system 7 extends to the upper end of the second water receiving tray 52, the drainage system 7 and the second water receiving tray 52 The second water receiving tray 52 is provided with a plurality of drainage holes through the drain pipe, and the cond...

Embodiment 2

[0069] In order to further solve the problem that during the use of the existing refrigerator, dust and dust will appear on the surface of the condenser, resulting in poor heat exchange effect of the condenser and increased energy consumption of the refrigerator, on the basis of Example 1, the implementation The refrigerator described in Example 1 is further optimized:

[0070] Specifically, such as Figure 2~3 As shown, the drainage system 7 includes a first connecting pipe 75, a drainage branch 71, a dust removal branch 72 and a reversing valve 73, the reversing valve 73 is a two-position three-way reversing valve, and the first connection Both ends of the pipe 75 are respectively connected to the water outlet of the evaporator 6 and the water inlet of the reversing valve 73; one end of the drainage branch 71 is connected to one of the water outlets of the reversing valve 73, so that The other end of the drainage branch 71 is connected with the first water receiving tray 2;...

Embodiment 3

[0082] In order to further solve the problem that during the use of the existing refrigerator, dust and dust will appear on the surface of the condenser, resulting in poor heat exchange effect of the condenser and increased energy consumption of the refrigerator, on the basis of Example 1, the implementation The refrigerator described in Example 1 is further optimized:

[0083] Specifically, such as Figure 4~5As shown, the drainage system 7 includes a circulation branch 74 and a second connecting pipe 76, and the two ends of the second connecting pipe 76 are connected to the water outlet of the evaporator 6 and the water inlet of the first water receiving tray 2 respectively. The two ends of the circulation branch 74 are respectively connected to the water outlet of the first water receiving pan 2 and the second water receiving pan 52, and the defrosting water on the evaporator 6 passes through the second water receiving pan 52. The connecting pipe 76 flows into the first wa...

Abstract

The invention provides a refrigerator. The refrigerator comprises a refrigerator body and a compressor bin. A compressor, a condenser and a first water pan located at the lower side of the condenser are arranged in the compressor bin. The refrigerator body is provided with a drainage system communicated with the compressor bin, the drainage system is communicated with the first water pan through a drainage pipe, a second water pan arranged at the upper side of the condenser is further included, the drainage system is communicated with the second water pan through a drainage pipe, the second water pan is provided with a plurality of drainage holes, and condensed water in the second water pan drips onto the condenser through the drainage holes and flows into the first water pan along the condenser. The refrigerator is simple in structure, capable of effectively removing dust of the condenser, capable of achieving cyclic utilization of defrosting water of the evaporator and high in resource utilization rate.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a dust removal device for a refrigerator condenser. Background technique [0002] With the changes in market demand and the advancement of refrigerator production technology, the market share of large-air-cooled refrigerators is getting higher and higher. In order to improve the refrigeration cycle efficiency of refrigerators, more and more large air-cooled refrigerators use forced air circulation to cool the condenser. [0003] Generally, such as figure 1 As shown, the compressor 01', the bottom cooling fan 02' and the condenser 03' are arranged in sequence at the bottom of the large air-cooled refrigerator, and the first water receiving tray 04' is set under the condenser 03', and the bottom cooling fan 02' passes through the fan The bracket 05' is fixed and installed, and the wind-shielding foam 06' is arranged on the condenser 03' to block the air, so as to improve th...
