Fig. 6 is a schematic bottom view of the refrigerator 100 shown in fig. 1. The bottom of the box body 110 is limited with the press cabin 400, and the press cabin 400 is positioned behind the cooling chamber 150, so that the whole press cabin 400 is positioned below the freezing compartment 140, as before, the freezing compartment 140 does not need to give way for the press cabin 400, the depth of the freezing compartment 140 is ensured, and articles which are large in volume and not easy to divide can be placed conveniently. 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 111 of the compressor compartment 400, respectively, and to complete the circulation of the heat dissipating air flow in the rear wall 111 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 pressure cabin 400, the skilled person usually increases the number of the rear air inlet and outlet holes of the rear wall 111 of the pressure cabin 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.

When the evaporators 200 need to be separately arranged in the variable temperature compartment 130 and the freezing compartment 140, if the evaporators 200 are transversely arranged, that is, the length direction of the cross section of the evaporators 200 is parallel to the width direction of the box body 110, the size selection of the evaporators 200 and the blowing fans 145 needs to be reduced by considering the thickness of the foaming layer, the safety distance between the blowing fans 145 and the evaporators 200 and other factors, which affects the refrigeration performance of the evaporators 200 and the blowing fans 145, and results in low refrigeration efficiency, small installation space and difficult installation. The utility model provides a length direction that sets its cross section with evaporimeter 200 is on a parallel with the thickness direction of box 110, can make evaporimeter 200's whole volume bigger, and refrigeration efficiency improves, and installation space is spacious, is convenient for install evaporimeter 200 and air supply fan 145.

In some alternative embodiments, the four-door refrigerator 100 shown in fig. 7 has two freezing compartments arranged in parallel, or two temperature-changing compartments arranged in parallel, or one freezing compartment and one refrigerating compartment arranged in parallel, or one temperature-changing compartment and one refrigerating compartment arranged in parallel.

The utility model discloses refrigerator 100 is owing to put at the bottom evaporator 200, the effective volume of compartment has been increased, evaporator 200 sets the length direction of cross section to the thickness direction of box 110 simultaneously, a new evaporimeter setting thinking is provided, be particularly useful for the embedded refrigerator of four opening doors, and the diapire of cooling chamber 150 in the below of evaporimeter 200 is formed with water collector 300 that has first slope district section 161 and second slope district section 162, be used for accepting the defrosting water that evaporator 200 produced, the defrosting water that can make evaporator 200 produce gets into water collector 300 smoothly.

Further, the utility model discloses refrigerator 100 is through injecing the inclination of each district section to the diapire of cooling chamber 150 for it more accords with the characteristics that the air current flows, is favorable to the cooling and the flow of air current, can guarantee whole discharges simultaneously, effectively guarantees evaporator 200's operational reliability.
