The utility model discloses refrigerator 100's box 110 bottom is injectd and is pressed cabin 400, and presses cabin 400 to be located cooling chamber 150's rear for press cabin 400 wholly is in the below of freezing compartment 140, as before, freezing compartment 140 need not give way for press cabin 400 again, has guaranteed freezing compartment 140's the depth, is convenient for place the great difficult article of cutting apart of volume. The refrigeration system of the refrigerator 100 is a compression refrigeration system, and includes a compressor 401, a heat dissipation fan, and a condenser. The heat dissipation fan may be an axial flow fan. The compressor 401, the radiator fan and the condenser are arranged in the press cabin 400 at intervals in the transverse direction.
There are two common design concepts for the inlet and outlet of the compressor pod 400. One is to provide a rear air inlet hole facing the condenser and a rear air outlet hole facing the compressor 401 in the rear wall of the compressor compartment 400, respectively, and to complete the circulation of the heat dissipating air flow in the rear wall portion of the compressor compartment 400. In the other method, ventilation holes are respectively formed in the front wall and the rear wall of the compressor compartment 400 to form a heat dissipation circulation air passage in the front-rear direction. When it is necessary to increase the heat dissipation effect of the nacelle 400, a person skilled in the art usually increases the number of the rear air inlet holes and the rear air outlet holes of the rear wall of the nacelle 400 to enlarge the ventilation area, or increases the heat exchange area of the condenser, for example, a U-shaped condenser with a larger heat exchange area is adopted. The inventors have innovatively realized that the heat exchange area of the condenser and the ventilation area of the press compartment 400 are not as large as possible: in the conventional design scheme of increasing the heat exchange area of the condenser and the ventilation area of the compressor compartment 400, the problem of uneven heat dissipation of the condenser is caused, which adversely affects the refrigeration system of the refrigerator 100.
To this end, the present invention provides that the bottom wall of the box 110 defines a bottom air inlet 402 adjacent to the condenser and a bottom air outlet 403 adjacent to the compressor 401, which are transversely arranged, so that the circulation of the heat dissipating air flow is completed at the bottom of the refrigerator 100 without increasing the distance between the rear wall 111 of the box 110 and the cabinet. The refrigerator 100 reduces the occupied space and ensures good heat dissipation of the compressor chamber 400, thereby fundamentally solving the problem that the heat dissipation and the occupied space of the compressor chamber 400 of the embedded refrigerator 100 cannot be balanced, and having particularly important significance. The heat rejection blower is configured to cause ambient air around the bottom intake vent 402 to enter the compressor compartment 400 from the bottom intake vent 402, and to sequentially pass through the condenser, the compressor 401, and then to flow from the bottom outlet vent 403 to the external environment to reject heat from the compressor 401 and the condenser.
In addition, four corners of the bottom wall of the box body 110 may further be provided with supporting rollers, and the box body 110 is placed on a supporting surface through the four supporting rollers, so that a certain space is formed between the bottom wall of the box body 110 and the supporting surface.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and interpreted to cover all such other variations or modifications.
