Within 131.

In the existing refrigerator 100, the width (horizontal dimension) of the air duct is generally approximately the same as the width of the rear wall of the storage liner 130, and the air duct occupies too much space behind the storage compartment 131, so that the storage compartment 131 The reduction in the depth of the storage compartment affects the storage volume of the storage drawer 133 arranged in the storage compartment 131. In this embodiment, the air supply air duct 134 is located in the middle of the inner side of the rear wall of the storage liner 130 as a whole, and the width (lateral dimension) of the air supply air duct 134 is reduced, which reduces the space occupied by the air supply air duct 134.

In this embodiment, the air supply duct 134 is located directly behind the vertical beam 136, that is, the width of the air supply duct 134 is approximately the same as the width of the vertical beam 136, and the air supply duct 134 and the storage liner 130 The section corresponding to the rear wall of the storage liner 130 may be vertically arranged at a position approximately in the middle of the inner side of the rear wall of the storage liner 130. Therefore, when the lateral size of the storage space is difficult to increase, by changing the position of the air duct 134, the depth of the storage space is increased, and the storage volume of the side-by-side refrigerator 100 is increased.

In some alternative embodiments, a vertically extending vertical partition (not shown) may be provided in the transverse middle of the storage liner 130, and the storage compartment 131 is divided into two left and right storage spaces by the vertical partition. Correspondingly, the front side of the storage liner 130 also has a side-by-side door to open and close the corresponding storage space.

For the storage compartment 131 equipped with the storage drawer 133, correspondingly, the gradual diversion air duct directs the outlet air flow to two diagonal directions in the transverse direction of the storage drawer 133.

The number of air supply openings formed by the air supply duct 134 may be the same as the number of the storage drawers 133 arranged in the storage compartment 131 or the vertical direction of the storage drawers 133 arranged in one storage space. Accordingly, the diversion The number of covers 1341 is the same as the number of storage drawers 133. Each storage drawer 133 has a diversion cover 1341 obliquely above, so that airflow is blown from the upper opening of the storage drawer 133 to the storage drawer 133, increasing the airflow Smoothness of flow.

By placing the evaporator 101 horizontally in the cooling chamber, the evaporator 101 is prevented from occupying more space, and the storage volume of the storage compartment 131 at the upper part of the cooling chamber is ensured.

As shown in Figure 1, the box body includes a refrigerating liner 120, which is located in the storage liner 130 Right above the refrigerator compartment 121 is defined inside. A refrigerator compartment door 122 is provided on the front side of the refrigerator liner 120. The refrigerating compartment 121 may be divided into a plurality of storage spaces by a plurality of horizontal partitions 123 distributed vertically to facilitate the sorting and storage of items.

As shown in FIG. 1, the refrigerating compartment 121 may have an independent refrigerating evaporator 125 and a refrigerating blower 126, and the refrigerating evaporator 125 and the refrigerating blower 126 are arranged in the refrigerating chamber air duct 124 located inside the rear wall of the refrigerating liner 120, The refrigerating compartment air duct 124 has a refrigerating compartment air outlet 124a that sends air to the refrigerating compartment 121, and has a refrigerating compartment return air inlet 124b. The refrigerating compartment return air inlet 124b is formed at the lower end of the refrigerating compartment air duct 124 and is located in the refrigerating compartment. Below the evaporator 125.

More specifically, in some embodiments, as shown in FIG. 6, the compressor cabin 102 is located at the rear and lower part of the cooling chamber, so that the storage compartment 131 above the cooling chamber does not need to make way for the compressor cabin 102. The storage compartment 131 It can be a regular rectangular space, which is convenient for placing large and difficult-to-divide objects, and solves the pain point of not being able to place large objects in the lowermost storage compartment 131.

More specifically, as shown in FIG. 8, a compressor 104, a radiator fan 106, and a condenser 105 are arranged in the compressor cabin 102, which are sequentially spaced along the transverse direction.

In some embodiments, as shown in FIG. 8, the back wall of the compressor cabin is corresponding to the plate section of the compressor 104

At least one rear air outlet hole 1162a is formed in 1162.

In fact, before the present invention, those skilled in the art usually have a design idea to open a rear air inlet hole facing the condenser 105 on the rear wall of the compressor cabin 102 and a rear air outlet hole 1162a facing the compressor 104. The rear part of 102 completes the circulation of the heat dissipation airflow; or the front wall and the rear wall of the compressor cabin 102 are respectively formed with vents to form a heat dissipation circulating air path in the front and rear directions. When facing the problem of improving the heat dissipation effect of the compressor cabin, those skilled in the art usually increase the number of rear air inlets and rear air outlets 1162a on the rear wall of the compressor cabin 102 to expand the ventilation area, or increase the heat exchange area of the condenser 105, For example, a U-shaped condenser with a larger heat exchange area is used.

The applicant of the present invention creatively realized that the heat exchange area of the condenser 105 and the ventilation area of the compressor cabin are not as large as possible. In the conventional design scheme of increasing the heat exchange area of the condenser 105 and the ventilation area of the compressor cabin, it will bring The uneven heat dissipation of the condenser 105 has an adverse effect on the refrigeration system of the refrigerator 100. For this reason, the applicant of the present invention jumped out of conventional design ideas and creatively proposed a new solution different from the conventional design. As shown in Figures 7 and 8, the bottom wall of the refrigerator 100 defines a bottom adjacent to the condenser arranged horizontally. With the air inlet 110a and the bottom air outlet 110b adjacent to the compressor 104, the refrigerator 100 completes the circulation of the heat dissipation airflow at the bottom of the refrigerator 100, making full use of the space between the refrigerator 100 and the supporting surface, and there is no need to enlarge the rear wall of the refrigerator 100 and the cabinet The distance of the refrigerator has been reduced by 100 At the same time of space, good heat dissipation of the compressor cabin is ensured, which fundamentally solves the pain point of the inability to balance the heat dissipation and space occupation of the compressor cabin of the embedded refrigerator 100, which is of particular significance.

The heat dissipation fan 106 is configured to suck in ambient air from the surrounding environment of the bottom air inlet 110a and force the air to pass through the condenser 105 first, then pass through the compressor 104, and then flow from the bottom air outlet 110b to the surrounding environment, thereby compressing the condenser and 105 The machine 104 performs heat dissipation.

In the vapor compression refrigeration cycle, the surface temperature of the condenser 105 is generally lower than the surface temperature of the compressor 104. Therefore, in the above process, the outside air is used to cool the condenser 105 and then the compressor 104.

More specifically, in the preferred embodiment of the present invention, (the rear wall of the compressor cabin) the plate section 1161 of the back plate 116 facing the condenser 105 is a continuous plate surface, that is, the plate of the back plate 116 facing the condenser 105 There are no heat dissipation holes on section 1161.

The applicant of the present invention creatively realized that even without increasing the heat exchange area of the condenser 105, reducing the ventilation area of the compressor cabin in an abnormal state can form a better heat dissipation airflow path, and still achieve better heat dissipation. effect.

In the preferred solution of the present invention, the applicant broke through the conventional design ideas and designed the back wall (back plate 116) of the compressor cabin (the back plate 116) and the plate section 1161 corresponding to the condenser 105 as a continuous plate surface to seal the heat dissipation airflow entering the compressor cabin in the condensation At the condenser 105, the ambient air entering from the bottom air inlet 110a is more concentrated at the condenser 105, which ensures the uniformity of the heat exchange of each condenser section of the condenser 105, and facilitates the formation of a better heat dissipation airflow path. It can achieve better heat dissipation effect.

In addition, since the plate section 1161 of the back plate 116 facing the condenser 105 is a continuous plate surface and does not have air inlet holes, it avoids that the air outlet and inlet air in the conventional design are concentrated at the rear of the compressor room and cause blowout from the compressor room. The hot air enters the compressor cabin again without being cooled by the ambient air in time, which adversely affects the heat exchange of the condenser 105, thereby ensuring the heat exchange efficiency of the condenser 105.

In some embodiments, as shown in FIG. 8, both lateral side walls of the compressor cabin are formed with a side vent hole 119a. The side vent hole 119a may be covered with a ventilation cover 108, and the ventilation cover 108 is formed with a grille. Ventilation holes; the outer shell of the refrigerator 100 includes two lateral side panels 111, the two side panels 111 extend vertically to form two side walls of the refrigerator 100, and the two side panels 111 respectively form one The side opening 111a communicating with the corresponding side vent 119a allows the heat dissipation airflow to flow to the outside of the refrigerator 100. Therefore, the heat dissipation path is further increased to ensure the heat dissipation effect of the compressor cabin.

More specifically, the condenser 105 includes a horizontally extending first straight section 1051, a second straight section 1052 extending back and forth, and a transitional curved section (not numbered) connecting the first straight section 1051 and the second straight section 1052, thereby An L-shaped condenser 105 with an appropriate heat exchange area is formed. The back wall (back Plate 116) The plate section 1161 corresponding to the condenser 105 is also the plate section 1161 where the back plate 116 faces the first straight section 1051.

The ambient air entering from the side vent 119a directly exchanges heat with the second straight section 1052, and the ambient air entering from the bottom air inlet 110a directly exchanges heat with the first straight section 1051, thereby further entering the environment in the compressor cabin The air is more concentrated at the condenser 105 to ensure the uniformity of the overall heat dissipation of the condenser 105.

Further in particular, as shown in Figures 7 and 8, the refrigerator 100 includes a bottom plate, a supporting plate 112, two side plates 119 and a vertically extending back plate 116. The supporting plate 112 constitutes the bottom wall of the compressor cabin for carrying compression The engine 104, the heat dissipation fan 106 and the condenser 105, the two side plates 119 respectively constitute the two lateral side walls of the compressor cabin, and the vertically extending back plate 116 constitutes the rear wall of the compressor cabin.

More specifically, the bottom plate includes a bottom horizontal section 113 located on the front side of the bottom and a bending section bent and extending backward and upward from the rear end of the bottom horizontal section 113, and the bending section extends above the pallet 112, The compressor 104, the heat dissipation fan 106, and the condenser 105 are arranged on the support plate 112 at intervals along the transverse direction, and are located in the space defined by the support plate 112, the two side plates, the back plate 116 and the bending section.

The supporting plate 112 and the bottom horizontal section 113 together constitute the bottom wall of the refrigerator 100, and the supporting plate 112 and the bottom horizontal section 113 are spaced apart, so that the rear end of the bottom horizontal section 113 and the front end of the supporting plate 112 define the bottom opening , Wherein the bent section has an inclined section 114 located above the bottom air inlet 110a and the bottom air outlet 110b. The two side plates extend upward from the lateral sides of the pallet 112 to the lateral sides of the bending section respectively to close the lateral sides of the compressor cabin; the back plate 116 extends upward from the rear end of the pallet 112 To the rear end of the bending section.

Specifically, the bending section may include a vertical section 1131, the aforementioned inclined section 114, and a top horizontal section 115. The vertical section 1131 extends upward from the rear end of the bottom horizontal section 113, and the inclined section 114 is formed by The upper end of the vertical section 1131 extends backward and upward to above the pallet 112, and the top horizontal section 115 extends from the rear end of the inclined section 114 to the back plate to cover the compressor 104, the radiator fan 106 and the condenser 105 above.

The front surface of the inclined section 114 may be formed with a protrusion 114a protruding upward, and the protrusion 114a is formed with a through hole 114a1. As shown in FIG. 4, the refrigerator 100 further includes a drain pipe 140, one end of the drain pipe is connected to the drain port 130a, and the other end extends through the through hole 114a to an evaporating dish (not labeled) provided in the compressor cabin 102 In order to drain the defrosting water into the evaporating dish, the evaporating dish is generally located below the condenser 105, and the heat emitted by the condenser 105 and the compressor 104 evaporates the defrosting water in the evaporating dish. The refrigerator 100 further includes a partition 117. The partition 117 is arranged at the rear of the bending section. The front part of the partition 117 is connected with the rear end of the bottom horizontal section 113, and the rear part is connected with the front end of the pallet 112, so as to open the bottom It is divided into a bottom air inlet 110a and a bottom air outlet 110b arranged horizontally.

It can be seen from the foregoing that the bottom air inlet 110a and the bottom air outlet 110b of this embodiment are defined by the partition 117, the supporting plate 112, and the bottom horizontal section 113, thereby forming a groove-shaped bottom air inlet with a larger opening size 110a and the bottom air outlet 110b increase the air inlet and outlet areas, reduce the air inlet resistance, and make the air flow smoother, and the manufacturing process is simpler, so that the overall stability of the compressor cabin is stronger.

In particular, the applicant of the present invention creatively realized that the slope structure of the inclined section 114 can guide and rectify the airflow of the inlet air, so that the airflow entering from the bottom air inlet 110a flows to the condenser 105 more concentratedly, avoiding the excessive dispersion of the airflow The condenser 105 cannot pass more, thereby further ensuring the heat dissipation effect of the condenser 105; at the same time, the slope of the inclined section 114 guides the airflow from the bottom air outlet 110b to the front side of the ground air outlet, so that the air outlet The air flow flows out of the compressor cabin more smoothly, thereby further improving the smoothness of air flow.

Further particularly, in a preferred embodiment, the angle between the inclined section 114 and the horizontal plane is less than

45°, in this embodiment, the inclined section 114 has a better guiding and rectifying effect on the airflow.

Moreover, what is unexpected is that the inventor of the present application creatively realized that the slope of the inclined section 114 has a better suppression effect on airflow noise. In the prototype test, the compressor cabin with the aforementioned specially designed inclined section 114 The noise can be reduced by more than 0.65 decibels.

In addition, in the traditional refrigerator 100, the bottom of the refrigerator 100 generally has a carrier plate with a substantially flat structure, and the compressor 104 is arranged inside the carrier plate. The vibration generated during the operation of the compressor 104 has a greater impact on the bottom of the cabinet 100. However, in this embodiment, as mentioned above, the bottom of the refrigerator 100 is constructed as a three-dimensional structure with a special structure of the bottom plate and the support plate 112, which provides an independent three-dimensional space for the arrangement of the compressor 104, and the support plate 112 is used to carry the compressor 104. The impact of the vibration of the compressor 104 on other components at the bottom of the box 100 is reduced. In addition, by designing the refrigerator 100 as the above ingenious and special structure, the bottom of the refrigerator 100 has a compact structure and a reasonable layout, which reduces the overall volume of the refrigerator 100, and at the same time makes full use of the space at the bottom of the refrigerator 100 to ensure the compressor 104 and The heat dissipation efficiency of the condenser 105.

More specifically, the upper end of the condenser 105 is provided with a windshield 1056, and the windshield 1056 may be a windshield sponge to fill the space between the upper end of the condenser 105 and the bending section, that is, the windshield 1056 covers the upper end of the first straight section 1051, the second straight section 1052 and the transitional curved section, and the windshield The upper end of 1056 should abut the bending section to seal the upper end of the condenser 105, so that part of the air entering the compressor room does not pass through the space between the upper end of the condenser 105 and the bending section without passing through the condenser 105. As a result, as much air entering the compressor cabin as possible passes through the condenser 105 for heat exchange, and further improves the heat dissipation effect of the condenser 105.

In some embodiments, the refrigerator 100 further includes a windshield 107 extending back and forth. The windshield 107 is located between the bottom air inlet 110a and the bottom air outlet 110b, and extends from the lower surface of the bottom horizontal section 113 to the lower surface of the support plate 112 , And connected to the lower end of the partition 117 to use the windshield 107 and the partition 117 to completely isolate the bottom air inlet 110a and the bottom air outlet 110b, so that when the refrigerator 100 is placed on a supporting surface, the bottom wall of the refrigerator 100 is horizontally separated The space between the support surface and the support surface allows the outside air to enter the compressor cabin through the bottom air inlet 110a located on the lateral side of the windshield 107 under the action of the heat dissipation fan 106, and then flow through the condenser 105 and the compressor 104 in sequence. Finally, it flows out from the bottom air outlet 110b on the other lateral side of the windshield 107, thereby completely isolating the bottom air inlet 110a and the bottom air outlet 110b, ensuring that the external air entering the condenser 105 and the heat dissipation from the compressor 104 The air will not flow, which further ensures the heat dissipation efficiency.
