[0039] The following will describe in detail the refrigeration equipment and its control method of the present invention with reference to the accompanying Figures 1 - 6 drawings.

[0040] Embodiment 1

[0041] This embodiment will describe in detail the refrigeration equipment of the present invention.

[0042] The refrigeration equipment of this embodiment includes a refrigerator main body 10 and a cold fan assembly. Among them, the cold fan assembly is arranged on the door body 101 of the refrigerator main body 10. The cold fan assembly has a heat exchange space 201. The heat exchange space 201 is isolated from the refrigerating space and the freezing space of the refrigerator main body 10. And an air inlet 202 and an air outlet 203 are also arranged on the door body 101. Both the air inlet 202 and the air outlet 203 are communicated with the heat exchange space 201, as Figure 1 and Figure 2 shown. Preferably, the air inlet 202 is arranged at the top and / or side of the door body 101, and the air outlet 203 is arranged on the front of the door body 101, as Figure 1 and Figure 2 shown. More preferably, a filter screen is arranged at the air inlet 202. The filter screen is used to filter out dust and impurities in the air to prevent dust and impurities from entering the interior of the heat exchange space 201. The refrigerator main body 10 can be a refrigerator structure in the prior art, which is used for food refrigeration and freezing. The refrigerator main body 10 can be a double-door structure or a single-door structure. The cold fan assembly is arranged on at least one door body 101 of the refrigerator main body 10, as Figure 1 and Figure 2 shown.

[0043] The refrigeration device of this embodiment includes a refrigerator main body 10 and a cold fan assembly. Among them, the cold fan assembly is arranged on the door body 101 of the refrigerator main body 10. The cold fan assembly has a heat exchange space 201. The heat exchange space 201 is isolated from the refrigerating space and the freezing space of the refrigerator main body 10. And an air inlet 202 and an air outlet 203 are also arranged on the door body 101. Both the air inlet 202 and the air outlet 203 are communicated with the heat exchange space 201. It can be seen that for the refrigeration device of this embodiment, on the one hand, it can refrigerate through the refrigerator main body 10 for food refrigeration and freezing, and on the other hand, it can also refrigerate the indoor environment through the cold fan assembly to achieve the purpose of cooling the kitchen. Since the heat exchange space 201 is isolated from the refrigerating space and the freezing space of the refrigerator main body 10, the low-temperature preservation function and the indoor cooling function of the refrigeration device can be independent of each other and do not interfere with each other. The refrigeration device of this embodiment integrates the cold fan assembly with the refrigerator main body 10, which can save kitchen space while cooling the kitchen. That is, the refrigeration device of this embodiment solves the technical problem in the prior art that when a fan is placed in the kitchen for cooling, the kitchen area is small, and after the fan is placed, it affects the normal operation of users in the kitchen.

[0044] According to a preferred embodiment, the cold fan assembly further includes a fan (the fan is not shown in Figure 4 the figure). The fan is arranged in the heat exchange space 201. The fan is used to suck the hot air at the air inlet 202 into the heat exchange space 201 and discharge the cold air in the heat exchange space 201 from the air outlet 203. The fan can be a centrifugal fan in the prior art. For the refrigeration device of the preferred technical solution of this embodiment, the cold fan assembly further includes a fan. Through the action of the fan, it can accelerate the entry of indoor hot air into the heat exchange space 201, and can also accelerate the discharge of the cold air in the heat exchange space 201 from the air outlet 203 to the indoor, thereby accelerating the cooling of the kitchen.

[0045] According to a preferred embodiment, the cold fan assembly further includes a first water tank 204 and a second water tank 205. A wet curtain 2011 is arranged in the heat exchange space 201.

In the refrigeration device of the preferred technical solution of this embodiment, a wet curtain 2011 is arranged in the heat exchange space 201. The wet curtain 2011 can absorb the ice water entering the heat exchange space 201. Then, the hot air entering the heat exchange space 201 through the air inlet 202 can exchange heat when passing through the wet curtain 2011 and generate wet and cool air. The wet and cool air enters the kitchen through the air outlet 203, thereby realizing the cooling of the kitchen. The heat-exchanged ice water dripping from the wet curtain 2011 can be collected by the second water tank 205. In the refrigeration device of the preferred technical solution of this embodiment, a wet curtain 2011 is arranged in the heat exchange space 201. The wet curtain 2011 can extend the residence time of the ice water in the heat exchange space 201, thereby enhancing the heat exchange effect between the hot air and the ice water, and further enhancing the cooling effect on the kitchen.

[0046] According to a preferred embodiment, a temperature sensor, a water level sensor and a submersible pump 2051 are arranged in the second water tank 205.

The water level in the second water tank 205 can be monitored through the water level sensor. When the water level in the second water tank 205 is too low, the amount of water is increased in the first water tank 204 to ensure that the wet curtain 2011 absorbs enough ice water, thereby ensuring the heat exchange effect between the hot air and the ice water.

[0047] According to a preferred embodiment, the cold fan assembly further includes an ice maker 206 and an ice storage box 207. The ice maker 206 is used to generate ice cubes, the ice storage box 207 is used to collect the ice cubes generated by the ice maker 206, and an ice inlet 2041 is arranged on the first water tank 204.

[0048] According to a preferred embodiment, the cold fan assembly further includes a water inlet assembly.
