The dew-removing component 400 further comprises a housing, the dew-removing air duct 410 is formed in the housing, the housing is provided with a cavity with an opening at the front end, the front end of the housing abuts against the rear side surface of the middle beam 220, and the dew-removing air duct 410 is formed between the housing and the middle beam 220. Before the refrigerator is assembled, the middle beam 220 is detachably arranged on the refrigerator body 100, and the refrigerator body 100 is connected with the middle beam 220 in a clamping manner; after the refrigerator is assembled, the center sill 220 is fixed to the case. In some embodiments, the box 100 and the center sill 220 are screwed together by fasteners. In other embodiments, the thickness of the middle beam 220 at the dew removal assembly 400 is thinner to facilitate heat conduction of the dew removal assembly 400.

In the present embodiment, the dew condensation removing duct 410 is disposed in the separation layer 200, and the dew condensation removing duct 410 is located at the front side of the separation layer 200. The dew-removing air duct 410 extends along the length direction of the front side of the separation layer 200, so that when the dew-removing air duct 410 is heated, the middle beam 220 is uniformly driven to be heated, and dew is removed from the middle beam 220.

The front side wall of the dew-removing air duct 410 is the center sill 220, and the dew-removing air duct 410 extends along the length direction of the center sill 220. The projection of the middle beam 220 on the front and back direction of the dew-removing air duct 410 is thinner, so that the heat in the dew-removing air duct 410 is conducted to the front side surface of the middle beam 220.

In this embodiment, the rear side surface of the dew condensation removing air duct 410 is communicated with the air inlet duct 430 and the air outlet duct 440, and the air inlet duct 430 and the air outlet duct 440 are respectively located at the left end and the right end of the rear side surface of the dew condensation removing air duct 410 to extend the length of the dew condensation removing air duct 410 in the left-right direction, so that the heated length of the front side surface of the separation layer 200 is increased, and the dew condensation removing efficiency is improved.

In some embodiments, the air inlet duct 430 and the air outlet duct 440 are respectively connected to the left end surface and the right end surface of the dew-removing duct 410, and the arc-shaped transition of the dew-removing duct 410, the air inlet duct 430 and the air outlet duct 440 reduces the noise of the hot air flowing in the dew-removing component 400.

Currently, the upper refrigeration compartment 110 of a refrigerator is a refrigeration compartment, the lower refrigeration compartment 110 is a freezing compartment, and the temperature of the lower refrigeration compartment 110 is lower than that of the upper refrigeration compartment 110. When the refrigerator is opened, the condensation of the partition layer 200 near the lower refrigerating compartment 110 is more than that of the partition layer 200 near the upper refrigerating compartment 110, so that more heat needs to be removed from the lower part of the front side of the partition layer 200.

In the present embodiment, the heating wire 230 is disposed on the bottom wall of the dew-removing air duct 410, and the heating wire 230 extends along the length direction of the dew-removing air duct 410. In some embodiments, the heating wire 230 is disposed at a front sidewall of the dew-removing duct 410.

Fig. 8 is an enlarged view at a in fig. 7.

Referring to fig. 5, 7 and 8, in the present embodiment, the air inlet duct 430 extends in a front-rear direction, and has one end connected to the air duct assembly 300 and the other end connected to the dew condensation removing duct 410. The connection between the front end of the air inlet duct 430 and the dew-removing duct 410 is a chamfer 432, so that when hot air flows into the dew-removing duct 410 through the chamfer 432, the starting noise of the air is small. The rear end of the air inlet duct 430 extends downward to protrude the separation layer 200 and into the air duct assembly 300, so that the hot air of the air duct assembly 300 flows upward from the lower side of the cabinet 100 into the dew condensation removing assembly 400. In some embodiments, the inner cavity of the air inlet duct 430 is gradually enlarged from the rear to the front of the air inlet duct 430 to slow down the flow rate of the hot air flow.

The intake duct 430 is further provided with a damper 431, and the damper 431 is used for closing and opening the intake duct 430. When the refrigerator is refrigerated, the damper 431 is closed to prevent cool air from entering the dew removal assembly 400; when the refrigerator is defrosted, the damper 431 is opened so that the hot air flow of the air duct assembly 300 can flow into the dew removal assembly 400. Specifically, the damper 431 is disposed at an end of the intake air duct 430 facing the air duct assembly 300. In some embodiments, damper 431 may be a solenoid valve or a channel divider plate.

Referring to fig. 5 and 6, in the present embodiment, the air outlet duct 440 extends in the front-rear direction, and one end of the air outlet duct is connected to the air duct assembly 300, and the other end is connected to the dew condensation removing duct 410. The rear end of the air outlet duct 440 extends downward to extend into the air duct assembly 300, so as to facilitate the discharge of the hot air flow in the dew removing assembly 400. In some embodiments, the air outlet duct 440 is provided with a solenoid valve to control the on/off of the air outlet duct 440.

Referring to fig. 1 to 8, in the present invention, when the refrigerator is in a cooling state, the air duct assembly 300 is communicated with the two cooling compartments 110 to transfer cooling energy to the two cooling compartments 110, and at this time, the damper 431 is closed, and the air duct assembly 300 is disconnected from the air intake duct 430. The heating wire 230 in the separation layer 200 starts to operate, and the heating wire 230 heats the center sill 220, so that in the process of opening and closing the refrigerator door, dew on the center sill 220 is removed, the corrosion of the dew on the refrigerator body 100 is prevented, and the using satisfaction of a user can be improved.

When the running time of the refrigerator is too long and the frost layer of the evaporator is thick to influence the cold conduction of the refrigerator, the refrigerator starts a defrosting mode. At this time, the heater 310 starts heating to heat and defrost the evaporator frost layer, the cooling compartments 110 are disconnected from the air duct assembly 300, the damper 431 is opened, the air duct assembly 300 is communicated with the dew condensation removing assembly 400, and the heating wire 230 is closed. A part of heat of the heater 310 is conducted into the air duct assembly 300, is transmitted into the air inlet duct 430 through the air duct assembly 300, and is transmitted into the dew removing duct 410 through the air inlet duct 430 to heat the dew removing duct 410, and the dew removing duct 410 heats the center sill 220 in the heating process, and after the temperature rise is completed, hot air in the dew removing duct 410 is finally discharged through the air outlet duct 440.

During defrosting of the refrigerator, the heater 310 can conduct heat to the dew-removing air duct 410 while defrosting the evaporator so as to remove dew on the front end of the partition layer 200, thus fully utilizing the heat of the heater 310 and improving the energy utilization rate of the refrigerator. Moreover, after the refrigerator is defrosted, the temperature in the dew-removing air duct 410 is high, the heating wire 230 can be started after the defrosting is finished for a period of time, and the starting time of the heating wire 230 is shortened, so that the energy consumption of the refrigerator is reduced.

In the present invention, the two refrigeration compartments 110 have a temperature difference with the outside, and when the refrigeration compartments 110 are opened, the cold air in the refrigeration compartments 110 contacts with the gas in the outside environment, so that the center sill 220 is susceptible to dew due to the temperature difference. During defrosting, the heater wire 230 stops operating and the heater 310 operates. The heater 310 provides heat for defrosting the refrigerator, and in order to fully utilize the heat of the heater 310, the heater 310 transfers the heat into the duct assembly 300. At this time, the air duct assembly 300 is not communicated with the two refrigerating compartments 110, the dew removing air duct 410 is communicated with the air duct assembly 300, and the air duct assembly 300 transmits heat into the dew removing air duct 410, so that the heat of the heater 310 is used for heating the center sill 220 and removing dew from the center sill 220 during defrosting of the refrigerator when the heating wires 230 are not operated, thereby improving the energy utilization rate of the refrigerator and reducing the use cost of the refrigerator.
