Background

Refrigerators are a kind of household electrical appliances which are indispensable for most families, wherein air-cooled refrigerators are popular in the market at present because the air-cooled refrigerators have the characteristic that frost is not easy to form in storage rooms. The air-cooled refrigerator refrigerates the storage chamber by circulating cold air, and because moisture (such as moisture brought by food) inevitably exists in the storage chamber, the moisture carried by the air in the storage chamber is condensed on the evaporator when the air enters the evaporation chamber, and the heat exchange performance of the evaporator is affected, the air-cooled refrigerator is usually provided with a heater for heating and defrosting the evaporator regularly.

In the related technology, in the heating defrosting process of the evaporator, part of frost on the evaporator is heated to sublimate into water vapor directly, and the water vapor floats into a storage chamber along with hot air flow, so that the temperature in the storage chamber is increased during defrosting.

Specifically, in the defrosting process, the heater is electrified to generate heat, so that part of the frost on the surface of the evaporator 60 is melted, and a small part of the frost is heated to be sublimated into water vapor directly, and floats along the freezing air duct 23 along with hot air flow, when the water vapor floats up to be in contact with the top wall 121 of the inner container 12, as the first cold storage device 30 stores a certain amount of cold in the refrigerating process of the refrigerator 1, the water vapor is suddenly cooled to be condensed on the top wall 121 and flows down or drops along with the side wall 123 of the inner container 12, so that most of the water vapor generated in the defrosting process of the refrigerator 1 is condensed on the top wall 121 of the inner container 12, the water vapor entering the storage chamber in the defrosting process is greatly reduced, the temperature rise in the storage chamber is avoided, and the influence of the defrosting process on the temperature in the storage chamber is reduced; in addition, as the water vapor entering the storage chamber in the defrosting process is reduced, the water in the freezing air duct 23 re-entering the storage chamber in the next refrigerating process is reduced, so that the frost re-condensed on the surface of the evaporator 60 is reduced, and the influence on the heat exchange performance of the evaporator 60 is reduced.

It should be further noted that, in the embodiment of the present application, by disposing the first cold accumulation device 30 in the foaming layer 13 of the refrigerator 1, rather than directly in the freezing air duct 23, the first cold accumulation device 30 does not occupy the space of the freezing air duct 23, so as to ensure that the freezing air duct 23 has enough installation space and over-wind space, and does not affect the assembly of other structures in the freezing air duct 23; further, the foaming layer 13 has a heat insulating effect, and can reduce the loss of the cold energy stored in the first cold storage device 30, so that the first cold storage device 30 can be in a low temperature state for a long time.

The distance from the first wall 125 to the surface of the top wall 121 decreases from the end connected to the side wall 123 to the end far from the side wall 123, which means that the first wall 125 may be an inclined surface or an arc surface.

It will be appreciated that, through the above arrangement, the bulge 124 is formed at the connection between the top wall 121 and the side wall 123, and the first wall 125 is inclined or curved, so that the water drops condensed on the top wall 121 during defrosting can flow down along the second wall 126 and the first wall 125 to the side wall 123 and down along the side wall 123, thereby avoiding the water drops condensed on the top wall 121 from directly dropping onto the evaporator 60 or the heater below.

In the embodiment of the present application, the first regenerator 30 includes a regenerator body and a regenerator liquid filled in the regenerator body. The cold storage liquid may be a liquid which is not frozen in a low-temperature environment and which can maintain good fluidity.

Specifically, during the refrigeration process of the refrigerator 1, the temperature of the side wall 123 of the liner 12 is reduced, and the second cold accumulation device 40 contacts with the side wall 123 of the liner 12, so that the second cold accumulation device 40 can store a certain amount of cold, during the defrosting process, part of the frost on the evaporator 60 is sublimated into water vapor directly, the water vapor floats upwards along with hot air flow, and the second cold accumulation device 40 releases the cold during the defrosting, wherein part of the water vapor condenses on the side wall 123 when encountering cold during the defrosting, so that the amount of the water vapor floating upwards is reduced, and most of the water vapor floating to the top wall 121 can condense on the top wall 121, so that the water entering the storage chamber from the refrigerating air duct 23 is further reduced.

Referring to fig. 3, in the embodiment of the present application, the refrigerator 1 further includes an evaporator 60, and the evaporator 60 is disposed in the cooling air duct 23; the refrigerating air duct structure 20 comprises a first air duct cover plate 21 and a second air duct cover plate 22, and the first air duct cover plate 21 and the second air duct cover plate 22 are sequentially connected up and down along the height direction of the refrigerator 1; the second cold accumulation device 40 is disposed on a portion of the side wall 123 opposite to the first air duct cover 21, and the evaporator 60 is disposed opposite to the second air duct cover 22.

In one embodiment, the refrigerator 1 further includes a filter disposed in the freezing air duct 23 to absorb moisture in the freezing air duct 23.

It will be appreciated that by providing the filter in the freezer tunnel 23, during defrosting of the refrigerator 1, the filter may absorb part of the moisture in the freezer tunnel 23, thereby further reducing the moisture entering the storage compartment during defrosting.

In one embodiment, the freezer tunnel structure 20 further includes a motorized damper for controlling the communication and blockage of the storage compartment with the freezer tunnel 23.

It can be understood that by arranging the electric air door, in the refrigerating process of the refrigerator 1, the electric air door communicates the storage chamber with the refrigerating air duct 23, and at the moment, the cold air in the refrigerating air duct 23 flows into the storage chamber from the refrigerating air duct 23 under the drive of the refrigerating fan, so that the refrigerating of the storage chamber is realized; during defrosting of the refrigerator 1, the electric damper partitions the storage chamber from the freezing air duct 23, thereby preventing water vapor generated during defrosting from entering the storage chamber, and thus preventing temperature rise in the storage chamber.

Specifically, the freezing air duct structure 20 has a plurality of air openings communicating the storage chamber and the freezing air duct 23, and the electric damper is installed at the air openings, and the communication and the blocking of the storage chamber and the freezing air duct 23 are realized by exposing or closing the air openings. Preferably, because the water vapor generated during defrosting floats up with the hot air flow, it is not necessary to provide a motorized damper at each of the tuyeres, but only at one or more tuyeres near the top wall 121.

Referring to fig. 1, in the embodiment of the present application, the refrigerator 1 further includes a drain pipe 50, a portion of the drain pipe 50 is disposed in the foaming layer 13, one end of the drain pipe 50 is communicated with the freezing air duct 23, and the other end of the drain pipe 50 is communicated with the compressor compartment.

Specifically, the drain pipe 50 has a first pipe orifice communicating with the freezing air duct 23, and in the defrosting process of the refrigerator 1, water melted by the evaporator 60 and condensed water condensed by the first cold accumulation device 30 and the second cold accumulation device 40 flow downward to the bottom of the freezing air duct 23, flow into the drain pipe 50 through the first pipe orifice, and further flow into the water receiving tray of the compressor bin from the drain pipe 50, thereby realizing the drainage of moisture in the freezing air duct 23 out of the refrigerator 1.
