The existing structure is that a fan is arranged in an air duct of a refrigerating device, return air is delivered to the refrigerating device through the air duct, the return air rapidly flows through the refrigerating device, the cold quantity exchange efficiency is low, and the refrigerating effect is poor.

To this end, with reference to fig. 1 to 3, an embodiment according to a first aspect of the present invention proposes a refrigeration assembly for a chamber of a refrigerator, comprising: the refrigerator comprises a refrigeration device 100, a cover 200 and a fan 300, wherein the refrigeration device 100 is installed on the side wall of a chamber 410, the cover 200 is connected to the side wall of the chamber 410 and covers the refrigeration device 100, the cover 100 is provided with a ventilation hole 210 and a cold air outlet 220, the cold air outlet 220 is positioned above the refrigeration device 100, and the ventilation hole 210 is correspondingly arranged at the lower part of the refrigeration device 110; the blower 300 is connected to the cover 200 and correspondingly disposed at the lower portion of the refrigeration device 100, the air inlet 310 of the blower 300 is communicated with the chamber, and the air outlet 320 of the blower is communicated with the ventilation hole 210 and faces the refrigeration device 100. The cover member 200 covers the refrigeration apparatus 100, corresponds to an air guide cover, and sends all the air blown out from the air outlet 320 to the lower portion of the refrigeration apparatus 100, and the cover member 200 shields the refrigeration apparatus 100 to prevent a user from touching the refrigeration apparatus 100, thereby eliminating the risk of frostbite. The fan 300 draws air from the air inlet 310 located in the cavity 410, discharges air from the air outlet 320, and directly blows to the refrigerating device 100 through the ventilation hole 210 without passing through an air duct in the middle, so that the air duct resistance and the noise in the conveying process are eliminated, the energy consumption of the fan 300 can be reduced, and the noise of the refrigerator 400 in operation is reduced. The fan 300 corresponds to the lower part of the refrigeration device 100, so that the air sucked by the fan 300 can flow through the whole refrigeration device 100 from bottom to top, the contact area and the contact time between the air sucked by the fan 300 and the refrigeration device 100 are increased, and the cold exchange efficiency is improved.

The fan 300 draws air from the chamber 410 of the refrigerator 400, and directly blows the air to the lower part of the refrigeration device 100 through the ventilation hole 210 for cold energy exchange, and because the cold air outlet 220 is positioned above the refrigeration device 100, the air blown out from the air outlet 320 flows through the refrigeration device 100, and gradually moves upwards and cools; with the temperature reduction, the specific gravity of the air increases, and the air with a higher position will add pressure to the air blown out from the air outlet 320, so that the air blown out from the air outlet 320 is forced to fill the flow direction section of the refrigeration device 100, which is beneficial to improving the efficiency of cold quantity exchange and improving the refrigeration effect.

Referring to fig. 3 and 5, according to some embodiments of the first aspect of the present invention, in order to prevent the return air drawn by the fan 300 from leaking toward the lower side of the refrigeration device 100, the covering member 200 is provided with a wind shield 240 for sealing the lower side of the refrigeration device 100, and the wind shield 240 extends to the lower end of the contact refrigeration device 100 or the side wall of the cavity 210, so as to ensure that the wind blown by the fan 300 to the refrigeration device 100 can only move upward, and cannot overflow downward, thereby improving the air supply efficiency. In addition, the side wall of the chamber 210 may be in contact with the cover 200 to seal directly under the refrigeration device 100, and the return air drawn by the blower 300 may be prevented from leaking to the bottom of the refrigeration device 100.

It can be understood that the size of the ventilation hole 210 is matched with the size of the air outlet 320 of the fan, and the position of the air outlet 320 corresponds to the position of the ventilation hole 210, so that the air blown out from the air outlet 320 by the fan 300 directly enters the refrigeration device 100 through the ventilation hole 210 for cold exchange, the resistance of the ventilation hole 210 to the air blown out from the air outlet 320 of the fan 300 is reduced, the wind resistance is further reduced, the energy consumption of the fan 300 is further reduced, and the noise generated during the operation of the refrigerator 400 is reduced. The air inlet 310 of the fan 300 is connected to the chamber 410 and faces the air outlet 320, so that the path of the wind drawn from the fan 300 can be shortened, and the wind resistance can be reduced.
