In some embodiments, the air inlet duct 16 and the air return duct 17 are both disposed on the back side of the second drawer chamber 22 and between the second drawer chamber 22 and the condensation chamber 15, so that the condensation chamber 15 is close to the second drawer chamber 22 to form hot air circulation, and meanwhile, the refrigeration function of other areas in the refrigerator is prevented from being affected.

In some embodiments, condenser 42 is a finned condenser 42, and finned condenser 42 is beneficial to improve the heat dissipation efficiency of condenser 42, and thus the heat exchange efficiency of second drawer chamber 22.

In some embodiments, the condenser 42 is provided with a heating wire (not shown in the drawings), and the heating wire is used for electric heating, so that when the refrigeration system stops working, the condenser 42 is thermally compensated, hot air is kept in the condensation chamber 15 at any time, and therefore the uninterrupted geothermal heat preservation function is realized.

It should be noted that, in some other embodiments, the heating wire may also be disposed on the inner sidewall of the second drawer chamber 22 to directly heat the air in the second drawer chamber 22. Such as the top wall of the second drawer compartment 22, directly heats the air at the top of the warm-keeping drawer 3.

Referring to fig. 7 and 8, in some embodiments, a fan (not shown) is disposed in the air inlet duct 16, the fan is used for generating wind power, a side of the fan facing the condensation chamber 15 is an air suction side, and a side of the fan facing the inside of the second drawer chamber 22 is an air supply side, so that hot air in the condensation chamber 15 can enter the second drawer chamber 22 through the air inlet duct 16.

Referring to fig. 7 and 8, in some embodiments, a filter (not shown) is disposed in the air inlet duct 16. The filtering device is made of materials with air purification function, such as activated carbon and the like. Therefore, when the hot air in the condensation chamber 15 can enter the second drawer chamber 22 through the air inlet duct 16, the hot air can be filtered and evolved through the filtering device, so that the warm-keeping drawer 3 has a fresh air function.

Referring to fig. 5 and 8, in some embodiments, the filtering device is disposed at a side of the fan close to the second drawer chamber 22, and the filtering device is detachably disposed in the air inlet duct 16, so that the filtering device can be periodically replaced from the second drawer chamber 22, which is convenient for a user to use.

The ventilation grille 18 is provided between the fan and the filter device, thereby isolating the fan from the filter device to facilitate installation and removal of the filter device while avoiding the fan being affected by the installation and removal of the filter device.

In some embodiments, the rear side wall of the second drawer compartment 22 is formed by stacking two layers of heat insulation plates, and the ventilation grille 18 is sandwiched and fixed between the two heat insulation plates, so that the ventilation grille 18 can be conveniently mounted and dismounted.

As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the metes and bounds of the claims, or equivalence of such metes and bounds are therefore intended to be embraced by the appended claims.

Claims (10)

1. A refrigerator, characterized by comprising:

the box body is internally provided with a condensing cavity and a drawer chamber which are separated from each other;

the condenser is arranged in the condensing cavity;

the warm-keeping drawer is movably arranged in the drawer chamber;

the air inlet duct is communicated with the condensation cavity and the drawer chamber and is used for conveying hot air in the condensation cavity into the drawer chamber;

and the return air duct is communicated with the drawer chamber and the condensation cavity, and air in the drawer chamber can return to the condensation cavity through the return air duct.

2. The refrigerator as claimed in claim 1, further comprising a cabinet container, wherein a refrigerating compartment is provided in the cabinet container;

the drawer chamber is arranged in the refrigeration chamber and is thermally isolated from the refrigeration chamber.

3. The refrigerator of claim 2, wherein the condensation chamber is provided in the cabinet container and at a rear side of the drawer chamber; the condensation cavity and the refrigeration compartment are isolated from each other.

4. The refrigerator as claimed in claim 1, wherein a fan is provided in the air intake duct, the fan generating wind to draw the hot air in the condensation chamber and to supply the hot air to the drawer chamber through the air intake duct.

5. The refrigerator as claimed in claim 4, wherein a filter is provided in the intake duct, the filter is provided at a side of the blower fan adjacent to the drawer chamber, and the filter is detachably provided in the intake duct.

6. The refrigerator as claimed in claim 5, wherein a ventilation grill is provided in the air intake duct, the ventilation grill being provided between the fan and the filtering device.

7. The refrigerator as claimed in claim 5, wherein the end of the air inlet duct communicating with the drawer chamber is provided with a damper, and the damper is located at one side of the filter device close to the drawer chamber; the air door is used for opening and closing the air inlet duct and sealing the filtering device in the air inlet duct.

8. The refrigerator as claimed in claim 1, wherein the drawer chamber is opened at a front side thereof, and the top, bottom, left, right and rear sidewalls of the drawer chamber are provided with heat insulating panels to form a heat insulating chamber therein.

9. The refrigerator as claimed in claim 1, wherein an air inlet and an air outlet are formed on a rear sidewall of the drawer chamber; the air inlet duct is communicated with the drawer chamber through the air inlet, and the drawer chamber is communicated with the return air duct through the air outlet;

an air inlet notch is formed in the rear side wall of the warm-keeping drawer and is opposite to the air inlet, so that hot air in the drawer chamber can pass through the air inlet notch to enter the warm-keeping drawer.

10. The refrigerator of claim 1, further comprising a heating wire provided on the condenser or an inner wall of the drawer chamber.
