The refrigeration system housing integrated module 300 may include a heating element 270, and the heating element 270 may be pre-installed within the refrigeration system housing 290 to form the refrigeration system housing integrated module 300. The heating member 270 may be spaced apart from the blower 220. The blower bracket 240 is made of a heat conductive material and serves to conduct heat of the heating member 270 to the blower 220. Because the heating element 270 can provide less heat to the fan 220 when the fan 220 is far away from the heating wire, the phenomenon that the fan 220 is difficult to defrost exists, and the heat of the heating element 270 is transferred to the fan 220 through the fan bracket 240, so that the defrosting of the fan 220 can be ensured, the defrosting of the fan 220 is more thorough, and the service life of the fan 220 is ensured.

Preferably, the drain opening 261 has a length and a width of between 3-45mm, for example, the drain opening 261 has a length of 12mm and a width of 6mm. If the size of the drain port 261 is too large, wind coming back from the ice making compartment 14 may flow from the space between the heat conductive shield 260 and the water tray 250 to the blower 220 through the drain port 261 without passing through the evaporator 210, which may reduce the cooling efficiency, while too small a size of the drain port 261 may affect the drainage effect. According to the design scheme provided by the embodiment, the size of the water outlet 261 is moderate, so that wind can be prevented from directly flowing to the fan 220 from the space between the heat conduction guard plate 260 and the water receiving disc 250 through the water outlet 261, and the water discharging effect and the refrigerating efficiency can be ensured.
