The technical solution in the embodiments of the present invention will be clearly and completely described below by taking a refrigeration appliance as an example and implementing the refrigeration appliance as a refrigerator with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 is a perspective view of a refrigerator cabinet as viewed generally from the back of the refrigerator. Fig. 2 is a schematic view of the mechanism compartment of fig. 1 with the cover separated. Referring to fig. 1 and 2, a refrigerator body 10 generally includes an outer case, an inner case defining a storage compartment, and a heat insulating layer (not shown) between the outer case and the inner case, and a front opening of the refrigerator body 10 is generally closed by an openable and closable door. The housing includes a top wall 11, a left side wall 12, a right side wall 13, a back wall 14, and a bottom wall 15. A machine chamber 2 is formed in a lower portion of the casing 10, and the machine chamber 2 is substantially configured by a left side wall 12, a right side wall 13, and a substantially zigzag bottom wall 15. A lid 21 that opens and closes the machine room 2. The cover 21 is substantially seamlessly joined to the back wall 14 of the housing 10 as a planar unit. The cover 21 can be considered to be substantially a part of the back of the case.

A refrigeration system of a refrigerator is generally a circulation refrigeration system including a compressor, a condenser, a capillary tube, evaporators corresponding to respective storage compartments, and a refrigeration line connecting the above refrigeration parts, thereby forming a cooling storage compartment.

In the present embodiment, both the compressor 3 and the condenser 4 are housed in the machine chamber 2 located at the lower portion of the casing 10. In order to enhance the convection of air from the inside of the machine room 2 to the outside to better discharge the heat in the machine room 2, a blower is generally provided in the machine room 2 to blow the air flow, thereby better cooling the machine room 2. Preferably, in the present embodiment, the blower fan 5 is disposed between the condenser 4 and the compressor 3, and blows air forcibly flowing from the condenser 4 to the compressor 3. In particular, the fan 5 may be positioned proximate or adjacent to the condenser 4 to accelerate the flow of air through the condenser 4.

The compressor 3, the fan 5, and the condenser 4 are fixed to the support plate 22 in parallel by a plurality of fixing devices. The support panel 22 is joined to the bottom wall 15 of the housing 10 in a substantially seamless, planar, integral relationship to generally define the bottom surface of the housing 10.

In order to allow the machine room 2 to perform air convection with the outside, an air inlet and an air outlet (not shown) communicating with the machine room are generally disposed on the box body, and particularly, both the air inlet and the air outlet (not shown) are disposed on the cover body 21 of the machine room 2 close to the ground.

During use, the refrigerator generates frost water or condensate which flows along a predetermined path and is collected to the receptacle through the drain pipe 6 and finally evaporated. The water receiver can set up on the condenser to can effectively utilize the heat dissipation of condenser, improve the evaporation efficiency of defrosting water in the first water receiver, so also can more be favorable to the condenser heat dissipation.

Further, an accommodating cavity can be formed on the condenser to accommodate the water receiver. So the water collector can press close to the condenser more and carry out the heat exchange more high-efficiently, improves the evaporation efficiency of defrosting water in the water collector more.

Fig. 3 is a schematic structural view of a condenser and a water receiver in an embodiment of the present invention. Fig. 4 is a schematic longitudinal cut view of fig. 3. As shown in fig. 3 and 4, the water receiver includes a first water receiver 71 and a second water receiver 72. The condenser 4 may be configured as a compact wire tube condenser integrally rolled into a spiral structure, the compact condenser 4 having a lateral shaft 41, and a common air flow duct 42 formed along the lateral shaft 41. And a fan 5 is arranged at one end adjacent to the condenser 4 to drive air flow to perform forced convection heat dissipation on the whole condenser 4. In order to fully utilize the existing structure of the condenser, the air duct 42 on the condenser 4 may be configured as a receiving cavity for receiving the first water receiver 71, so as to simply realize how the first water receiver 71 is disposed on the condenser 4. The defrost water or condensed water may first enter the first water receiver 71 through the drain pipe 6 and gradually evaporate therein. The second water receiver 72 is disposed below the first water receiver 71 and below the condenser 4 to receive water overflowing from the first water receiver 71.

The first water receiver 71 and the second water receiver 72 can be communicated through the overflow pipe 8. Part of the first water receptacle 71 extends out of the air duct 42 as a receiving chamber, and the overflow pipe 8 can be disposed right on the extended part of the first water receptacle 71. When the discharged defrosted water or condensed water is too much to exceed the volume of the first water receiver 71, the water is discharged into the second water receiver 72 along the overflow pipe 8. The water collection amount can be greatly increased through the matching of the first water receiver 71 and the second water receiver 72, and unnecessary trouble caused by water overflowing into the mechanical chamber 2 is avoided.

Fig. 5 is a schematic structural view of the first water receiver. As shown in fig. 4 and 5, the inner wall of the air duct 42 formed by the condenser 4 is curved. The first water receiver 71 is mounted on the inner wall of the air duct 42, and for the purpose of fitting, the first water receiver 71 also has an arc-shaped wall 711 that fits with the arc-shaped inner wall. The first water receiver 71 further has a side wall 712 connected to both ends of the arc-shaped wall 711, respectively. The receiving chamber of the first water receiver 71 is defined by an arc-shaped wall 711 and two side walls 712. The arc-shaped wall 711 of the first water receiver 71 can be tightly attached to the inner wall of the air duct 42. So first water collector 71 can install better and hold in wind channel 42, also helps increasing the area of contact of first water collector 71 and condenser 4, carries out the heat exchange more high-efficiently, improves the evaporation efficiency of first water collector 71 normal water more.

Fig. 6 is a longitudinal cut view of a first water receiver disposed on a condenser according to another embodiment of the present disclosure. As shown in fig. 6, the present embodiment is different from the above embodiments in that: the condenser 4 is recessed inward to form a receiving chamber 43, and a first water receiver 71 is installed in the receiving chamber 43. The arc-shaped wall 711 of the first water receiver 71 is also matched with the arc-shaped inner wall of the accommodating cavity 43 and is tightly attached to each other. This provides another possibility of placing the first water receiver 71 on the condenser 4.

In another embodiment of the present application, the following embodiments are different from the above embodiments: a vibration damper (not shown) is disposed between the first water receiver 71 and the condenser 4 to reduce vibration and noise between the first water receiver 71 and the condenser 4.

The condenser in each of the above embodiments is illustrated as a compact wire tube condenser, however, it will be apparent to those skilled in the art that the present invention can be practiced with other types of condensers.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
