The back of the storage cavity 101 is provided with an air outlet cover plate 104, and an air outlet channel is formed between the air outlet cover plate 104 and the back of the storage cavity 101. As for the refrigeration unit 200, the refrigeration unit 200 generally includes a housing 1 and a refrigeration circuit 2, the refrigeration circuit 2 includes a compressor (not shown), a condenser 21, a throttling device and an evaporator 22, which are connected together, an evaporation chamber 11 and a condensation chamber 12 are formed in the housing 1, the evaporator 22 is located in the evaporation chamber 11, an evaporation fan 3 is correspondingly arranged in the evaporation chamber 11, the condenser 21 and the compressor are located in the condensation chamber 12, and a condensation fan 4 is correspondingly arranged in the condensation chamber 12. The top of the evaporation chamber 11 is provided with a return air inlet 111 and an air outlet 112, the return air inlet 111 is communicated with the ventilation opening 103, and the air outlet 112 is communicated with the air outlet channel. Therefore, air in the storage cavity 101 enters the air return opening 111 through the ventilation opening 103, the air entering from the air return opening 111 exchanges heat through the evaporator 22 to form cold air, and the cold air is output to the air outlet channel from the air outlet 112, and is finally output to the storage cavity 101 from the air outlet hole on the air outlet cover plate 104 to refrigerate the articles.

In order to avoid the influence of the accumulation of foreign matters on the evaporator 22 during the circulation blowing process on the cooling efficiency. The following structural improvement design is carried out, and specifically:

the evaporation chamber 11 is also provided with a transversely arranged baffle 5, the side part of the baffle 5 is abutted against the side wall of the evaporation chamber 11, the first end part of the baffle 5 extends to the air return opening 111, the evaporator 22 and the evaporation fan 3 are transversely arranged in the evaporation chamber 11 side by side, and the evaporator 22 and the evaporation fan 3 are positioned below the baffle 5. Specifically, the evaporator 22 and the evaporation fan 3 are both located below the baffle 5, and the top shielding protection is performed on the evaporator 22 and the evaporation fan 3 through the baffle 5. Thus, in the actual use process, even if the impurities fall into the return air inlet 111 from the air vent 103, the baffle 5 is shielded at the tops of the evaporator 22 and the evaporation fan 3, the impurities can be effectively prevented from falling onto the evaporator 22 by the baffle 5, so as to ensure that the heat exchange surface of the evaporator 22 is not shielded by the impurities, and ensure that the evaporator 22 has high heat exchange efficiency.

For the baffle 5, in order to ensure smooth air inlet and outlet of the evaporation chamber 11, the second end of the baffle 5 extends to the air outlet 112; alternatively, the second end of the baffle 5 extends to a position between the air return opening 111 and the air outlet 112. Specifically, the baffle 5 can block the air heat exchanged by the evaporator 22 at the top, so as to prevent the air heat exchanged by the evaporator 22 from leaking from the air return opening 111 at the top, and ensure that the air after heat exchange smoothly enters the air outlet 112.

Wherein, baffle 5 except can stopping on debris fall to evaporimeter 22, can also play the effect of installation evaporating fan 3, specifically is: the first end of baffle 5 is provided with flanging structure 51, has seted up installing port 52 on flanging structure 51, and evaporation fan 3 sets up on installing port 52. Specifically, the evaporation fan 3 is mounted and fixed on the flange structure 51, and air introduced from the air return opening 111 enters the evaporation fan 3 through the mounting opening 52. And because the evaporator 22 and the evaporation fan 3 are transversely arranged side by side, the airflow blown out from the evaporation fan 3 is transversely blown to the evaporator 22 to realize heat exchange. The sides of the edge-turned structure 51 also abut against the side walls of the evaporation chamber 11, so that the edge-turned structure 51 has sufficient structural strength to mount and fix the evaporation fan 3.

In addition, in the case of the evaporator 22, the top of the evaporator 22 abuts on the baffle 5, so that the wind blown out from the evaporator fan 3 can be efficiently heat-exchanged via the evaporator 22. At the same time, the evaporator 22 can also be mounted and fixed by means of the baffle 5, for example: the top of the evaporator 22 can be connected with the baffle 5 at the top by welding or the like, and after the evaporation fan 3 is assembled on the baffle 5, the baffle 5 is fixed in the evaporation chamber 11 by screws or the like, so as to complete the integral assembly of the evaporator 22 and the evaporation fan 3. Preferably, the side wall of the evaporation compartment 11 is provided with a vertically arranged positioning rib 113, and the side of the evaporator 22 abuts against the positioning rib 113. Specifically, the lateral part of the evaporator 22 is positioned by the positioning blocking rib 113, and the positioning blocking rib 113 can effectively block the lateral part of the evaporator 22, so that the air flow blown out by the evaporation fan 3 is prevented from being directly conveyed to the air outlet 112 through the gap between the evaporator 22 and the side wall of the evaporation chamber 11, and the air can be effectively exchanged heat through the evaporator 22.

Through dispose baffle 5 in evaporation compartment 11, baffle 5 can shelter from the protection at the top to evaporimeter 22 to avoid the debris that the top dropped to pile up on evaporimeter 22 and influence evaporimeter 22 normal heat transfer, ensure that the not sheltered from by debris of evaporimeter 22 heat-transfer surface is in order to obtain good heat exchange efficiency, thereby can effectual reduction operation energy consumption.

Similarly, since the air cooling method is adopted, the evaporator 22 needs to be defrosted after a long time use, and correspondingly, the bottom of the evaporation chamber 11 needs to be configured with a design for discharging defrosted water. For this purpose, a heat-insulating partition 13 is arranged in the casing 1, the heat-insulating partition 13 divides the inside of the casing 1 into an evaporation chamber 11 and a condensation chamber 12, a drain hole 131 communicating the evaporation chamber 11 and the condensation chamber 12 is opened at the bottom of the heat-insulating partition 13, a water pan 60 and a drain pipe 6 are further arranged in the condensation chamber 12, and the drain pipe 6 is transversely arranged and inserted in the drain hole 131.

In order to avoid the cold air from leaking out from the drain hole 131 through the drain pipe 6 in the normal refrigeration process, the following structural improvement design is performed, specifically: the drain port 61 of the drain pipe 6 is arranged upward. Specifically, after the defrosting process is performed on the evaporator 22, the defrosting water is collected to the bottom of the evaporation chamber 11 and flows into the drain pipe 6 through the drain hole 131, while being arranged upward due to the drain hole 61 of the drain pipe 6. In the defrosting process, the defrosting water accumulated at the bottom of the evaporation chamber 11 cannot be completely discharged, and the defrosting water overflows from the water outlet 61 after the water level of the defrosting water in the evaporation chamber 11 exceeds the height of the water outlet 61. Thus, a water seal can be formed by the water discharge pipe 6, and the leakage of cold air can be reduced or avoided by the water seal formed by the water discharge pipe 6.

The height of the water outlet 61 is higher than that of the bottom surface of the evaporation chamber 11, so that a certain amount of defrosting water can be effectively accumulated at the bottom of the evaporation chamber 11 due to the higher height of the water outlet 61. So that the drain hole 131 is immersed in the defrosted water to achieve a more effective water sealing effect. In addition, a water collection groove 114 is formed in a region of the bottom surface of the evaporation chamber 11 near the water discharge hole 131. Specifically, the water collection groove 114 is formed concavely on the floor of the evaporation chamber 11 to facilitate efficient collection of the defrosting water. Meanwhile, the lower edge of the drainage hole 131 is flush with the bottom of the water collecting groove 114, so that only a small amount of defrosting water needs to be accumulated in the evaporation chamber 11, and the drainage hole 131 can be immersed in the defrosting water to obtain a good water sealing effect.

Further, in order to reduce the leakage of the cold air more effectively, the flange structure 51 extends downward to the bottom surface of the evaporation compartment 11, specifically, the flange structure 51 blocks between the evaporator 22 and the drain hole 131, so that after the air blown to the evaporator 22 by the evaporation fan 3 rebounds, the rebounded air can be prevented from flowing toward the drain hole 131 under the action of the flange structure 51, and the leakage of the cold air can be blocked more effectively.

Furthermore, in order to accelerate the evaporation speed of the defrosting water in the water pan 60, the top of the condensing chamber 12 is provided with a heat dissipation air outlet 121, the front and/or the side wall of the condensing chamber 12 is provided with a heat dissipation air inlet (not marked), the condenser 21 shields the heat dissipation air inlet, the heat dissipation air outlet 121 is provided with a condensation fan, and the condensation fan 4 is located above the water pan 60. Specifically, since the condensing fan 4 is located above the water pan 60, the external air is heat exchanged by the condenser 21 to form a high-temperature airflow which flows through the water pan 60 and is discharged from the condensing fan 4, so that the evaporation speed of the defrosting water in the water pan can be increased.

Meanwhile, for the vent 103 at the bottom of the storage cavity 101, the sundries are prevented from falling into the vent 103 more effectively. Then, the following structural improvement design is carried out, specifically: the air return cover plate 7 is further arranged in the storage cavity 101, the air return cover plate 7 covers the air vent 103, an air return channel is formed between the air return cover plate 7 and the bottom surface of the storage cavity 101, a lower flanging 71 is further arranged on the edge, close to the door body, of the air return cover plate 7, and an air return hole (not marked) is formed in the lower flanging 71. Specifically, the return air cover plate 7 can be fixedly installed in the storage cavity 101 in a screw mode and the like, the return air cover plate 7 is shielded and protected at the top of the vent 103, and meanwhile, return air is achieved through a return air channel formed between the return air cover plate 7 and the bottom surface of the storage cavity 101. In actual use, air in the storage cavity 101 enters the return air channel through the return air inlet 111 and enters the refrigeration unit 200 through the vent 103. The return air cover plate 7 is always fixed above the ventilation opening 103, so that sundries can be effectively prevented from directly falling into the ventilation opening 103; meanwhile, as the air return hole is formed in the lower flanging 71 formed in the front of the air return cover plate 7, even if sundries fall to the front side of the lower flanging 71 in the using process, the sundries are difficult to enter the air return hole, so that the using reliability is improved.

Finally, it should be noted that: 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.
