Problems solved by technology

In order to prevent the defrosting water in the air duct from dripping onto the fan, generally speaking, the fan is installed on the upper part of the evaporator. However, in the refrigerator with this structure, the fan and the air duct structure occupy a considerable part of the volume of the room, which reduces the capacity of the refrigerator. Volume ratio; secondly, the fan protrudes from the air duct structure, which is not beautiful; in addition, the drain located at the lower part of the air duct is far away from the fan, and the return air is blown into the air duct from the bottom of the air duct. risk of icing; and low air velocity over the sump, resulting in poor humidification

Embodiment Construction

[0048] This embodiment firstly provides a refrigerator 100, figure 1 is a schematic structural diagram of a refrigerator 100 according to an embodiment of the present invention.

[0049] The refrigerator 100 may generally include a box body 110, in which at least one inner container 120 with an open front is defined, and a storage compartment is defined in the inner container 120, the outer periphery of the inner container 120 is covered with an outer shell, and the outer shell and Insulation materials, such as foaming agents, are filled between the inner tanks 120 to avoid cooling loss. There are usually multiple inner tanks 120, such as refrigerated inner tanks, frozen inner tanks, temperature-changing inner tanks, etc., and the corresponding storage compartments are refrigerating chambers 121, freezing chambers 141, and variable temperature chambers. The specific quantity and function of the liner 120 can be configured according to the advance requirement. In some embodim...

Abstract

The invention provides a refrigerator. The refrigerator comprises an inner container, an air flue, an evaporator and a draught fan; a storage chamber is limited in the inner container, the air flue extends in the inner container from bottom to top along the rear wall of the inner container, the evaporator is arranged on the outer side of the rear wall of the inner container, and is configured to indirectly cool air in the air flue, the draught fan is arranged in the air flue and located on the lower portion of the air flue, and is configured to promote air, cooled by the evaporator, in the airflue to flow into the storage chamber. According to the refrigerator, the draught fan is arranged on the lower portion of the air flue, the evaporator is arranged on the outer side of the rear wall of the inner container, when wet air passes through the refrigeration area of the evaporator through the air flue, the wet air exchanges heat with the face of the rear wall of the inner container, dueto the fact that the temperature of the face of the rear wall of the inner container is higher than the temperature of the evaporator, the frost quantity of wet air is reduced, it is ensured that muchwater steam is brought into the storage chamber, the phenomenon that most part of the water steam is frozen by the evaporator and forms frost is avoided, the humidity of the storage chamber is improved, humidity of the food in the storage chamber can be conveniently stored, and food can be prevented from being air dried.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a refrigerator. Background technique [0002] The fan is an essential part of the air-cooled refrigerator, and its function is to improve the heat exchange efficiency of the evaporator through forced convection. In order to prevent the defrosting water in the air duct from dripping onto the fan, generally speaking, the fan is installed on the upper part of the evaporator. However, in the refrigerator with this structure, the fan and the air duct structure occupy a considerable part of the volume of the room, which reduces the capacity of the refrigerator. Volume ratio; secondly, the fan protrudes from the air duct structure, which is not beautiful; in addition, the drain located at the lower part of the air duct is far away from the fan, and the return air is blown into the air duct from the bottom of the air duct. risk of icing; and low air velocity over the sump, ...
