An air outlet duct 20 is formed between the first air duct cover plate 110 and the back of the inner container 200, and a return air duct 10 is formed between the second air duct cover plate 120 and the top of the inner container 200. The air return opening 11 is arranged on the second air duct cover plate 120. The evaporator 400 and the fan 600 are both fixedly connected with the second air duct cover plate 120, and the fan 600 is opposite to the air return opening 11. The auxiliary air outlet duct 30 is disposed on the left and right sides of the second duct cover plate 120. The auxiliary air outlet duct 30 is directly arranged on the second air duct cover plate 120, so that the structure is simple, and the compactness of the internal structure is favorably realized.

Specifically, referring to fig. 5 and 6, the second air duct cover plate 120 includes a bottom plate 121, a front side plate 122 disposed on the front side of the bottom plate 121, and two side plates 123 disposed on the left and right sides of the bottom plate 121, and the rear side of the bottom plate 121 is fixedly connected to the first air duct cover plate 110. The fan 600 is fixed on the bottom plate 121 and close to the front side plate 122. Referring to fig. 2 and 3, the evaporator 400 is disposed on the bottom plate 121 and adjacent to the first duct cover 110. In actual processing, the bottom plate 121, the front side plate 122, and the left and right side plates 123 are preferably formed by cutting and bending the same sheet of plate material, so that the processing is facilitated, and the structure is more stable.

Furthermore, a flange 124 is arranged on the side of the side plate 123 far away from the bottom plate 121, the flange 124 horizontally extends towards the inner side of the return air duct 10, partition plates 130 are further fixedly arranged on the left side and the right side of the bottom plate 121 respectively, the upper sides of the partition plates 130 are fixedly connected with the flange 124, and the front sides of the partition plates 130 are fixedly connected with the front side plate 122. Thus, the bottom plate 121, the side plate 123, the turned edge 124, the front side plate 122, and the partition plate 130 together enclose the auxiliary air outlet duct 30, the front end of the auxiliary air outlet duct 30 is provided with the top air outlet 31, and the rear end of the auxiliary air outlet duct 30 is communicated with the air outlet duct 20. By utilizing the existing structure of the second air duct cover plate 120, the auxiliary air outlet duct 30 separated from the return air duct 10 can be formed by the simple partition plate 130, the structure is simple, the existing structures of other parts are not required to be changed, and the applicability is strong.

Furthermore, a water pan 500 is fixedly arranged between the two partition plates 130, the evaporator 400 is arranged in the water pan 500, and condensed water generated by the evaporator 400 directly falls into the water pan 500 and then flows out through a water outlet 510 communicated with the water pan 500, so that the condensed water is prevented from dripping into the refrigerating space 50 from the top air return opening 11 and the top air outlet 31 through the bottom plate 121.

Further, in order to make the connection of the water pan 500 more reliable, referring to fig. 5 (the evaporator 400 and the water pan 500 are omitted), the first connection plate 140 is fixedly disposed between the two partition plates 130, the lower side of the first connection plate 140 is fixedly connected with the bottom plate 121, the left and right sides of the water pan 500 are respectively fixedly connected with the partition plates 130, and the front side of the water pan 500 is fixedly connected with the first connection plate 140. Because the first connection plate 140 is located between the water-receiving tray 500 and the fan 600, and the height of the first connection plate 140 is higher than that of the water-receiving tray 500, the condensed water in the water-receiving tray 500 can be further prevented from splashing to the position of the fan 600.

Further, a certain distance D is provided between the left and right sides of the evaporator 400 and the partition plate 130, referring to fig. 3, on one hand, the circulation of air is facilitated, on the other hand, the heat dissipation of the evaporator 400 is facilitated, and in addition, the influence on the air temperature in the auxiliary air outlet duct 30 due to the heat exchange generated between the evaporator 400 and the partition plate 130, and further the temperature uniformity in the refrigerating space 50 is also avoided.

Further, referring to fig. 3, a second connecting plate 150 is fixedly disposed on each partition plate 130, a third connecting plate 160 is fixedly disposed on one side of the evaporator 400 close to the first connecting plate 140, a first gap d1 is formed between the left side and the right side of the third connecting plate 160 and the adjacent partition plate 130, and a second gap d2 is formed between the second connecting plate 150 and the third connecting plate 160. Thus, a Z-shaped air circulation channel 40 is formed between the second connection plate 150 and the third connection plate 160, a part of return air at the front side fan 600 directly flows through the evaporator 400 to the air outlet duct 20 at the rear side, and another part of return air flows into the gaps at the left and right sides of the evaporator 400 through the Z-shaped air circulation channel 40, so that because airflow flowing to the rear side (i.e. in the direction close to the air outlet duct 20) is in the Z-shaped air circulation channel 40, cold air flowing out from the rear side of the evaporator 400 and flowing into the auxiliary air outlet duct 30 will not easily flow back to the fan 600 through the Z-shaped air circulation channel 40, and the whole air circulation system is more reliable and the temperature is more uniform.

Further, the bottom plate 121 includes a bottom plate horizontal portion 1211 and a bottom plate inclined portion 1212, a front side of the bottom plate inclined portion 1212 is inclined upward, the air return opening 11 and the top air outlet 31 are both disposed on the bottom plate inclined portion 1212, and the water receiving tray 500 is disposed on the bottom plate horizontal portion 1211. The air flow passing through the air return opening 11 and the top air outlet 31 is not straight up and down, but has a certain inclination angle, which is beneficial to the action area of the cold air in the refrigerating space 50, and the cold air is fully utilized to improve the refrigerating effect. Meanwhile, the bottom plate inclined portion 1212 also contributes to a small amount of condensed water splashed onto the bottom plate inclined portion 1212 dropping into the refrigerating space 50.

Further, the first connection plate 140 is fixedly disposed at the intersection of the bottom plate horizontal portion 1211 and the bottom plate inclined portion 1212, which facilitates the fixed installation of the first connection plate 140. If the first connecting plate 140 is fixedly installed on the bottom plate inclined portion 1212, it is not favorable for the first connecting plate 140 to be vertically disposed, and thus the installation of other components such as the water collector 500 is affected. If the first connection plate 140 is fixedly installed on the horizontal portion 1211 of the bottom plate, it is disadvantageous to achieve the compactness of the inner structure and to reduce the installation space of the evaporator 400 side.

What should be said finally is: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
