Embodiment 1

[0046] This embodiment describes the exhaust mechanism of the present invention in detail.

[0047] In this embodiment, it includes the freezing air cover 11 and the exhaust hole assembly, such as Figure 1~3 shown. Preferably, the freezing air shield 11 is installed on the box body and forms an accommodating cavity with the inner wall of the box, and the accommodating cavity is used for placing the freezing evaporator 2 and the defrosting heater 3 . More preferably, the freezing air cover 11 is also provided with an air outlet assembly and an air return assembly, and the air outlet assembly and the air return assembly have a first state in which the air outlet 111 and the return air port 112 are opened and the air outlet 111 and the air return port 112 are opened. The second state of closing; the vent assembly has a first state in which the freezing wind cover 11 communicates with the vent 121 and a second state in which the freezing wind cover 11 is separated from the vent ...

Embodiment 2

[0065] This embodiment describes the refrigerator of the present invention in detail.

[0066] The refrigerator of this embodiment includes the exhaust mechanism of any one of the technical solutions in Embodiment 1. The refrigerator of this embodiment includes the exhaust mechanism of any one of the technical solutions in Embodiment 1, which can not only ensure the normal refrigeration function, but also block the heat generated by the defrosting heater 3 from the gas in the refrigerator compartment during defrosting. Heat exchange is carried out, so as to avoid the temperature rise in the compartment and cause the temperature fluctuation in the compartment. That is, the refrigerator of this embodiment solves the technical problem in the prior art that the heat generated by the refrigerator during defrosting diffuses into the compartment, causing the temperature in the compartment to rise.

[0067] Such as figure 1 or image 3 As shown, the refrigerator in this embodiment ...

Embodiment 3

[0069] This embodiment describes in detail the exhaust gas control method of the refrigerator of the present invention.

[0070] In the exhaust control method of the refrigerator according to any technical solution in Embodiment 2, the defrosting heater 3 is in the working state, and the freezing air cover 11 is isolated from the refrigerator compartment to form an airtight space, so that the heat generated during defrosting is stored in the refrigerator. Inside the wind cover 11 ; after the defrosting is finished, the exhaust hole 121 is opened and the hot air in the freezing wind cover 11 is discharged through the exhaust hole 121 .

[0071] In the exhaust control method of the refrigerator in this embodiment, the defrosting heater 3 is in the working state, and the freezing air cover 11 is isolated from the refrigerator compartment to form a closed space, so that the hot air generated during defrosting is stored in the freezing air cover 11; After the defrosting is finished...

Abstract

The invention discloses an exhaust mechanism, a refrigerator and an exhaust control method of the refrigerator, relates to the technical field of refrigerators, and solves the technical problem that in the prior art, heat generated in the defrosting period of the refrigerator is diffused into a compartment, causing temperature rise in the compartment again. The exhaust mechanism comprises a freezing fan cover and an exhaust hole assembly, when a freezing evaporator is in a working state, an air outlet assembly and an air return opening assembly on the freezing fan cover are in an open state, and the exhaust hole assembly is in a closed state; when a defrosting heater is in a working state, the air outlet assembly and the air return opening assembly are in a closed state, and the exhaust hole assembly is in a closed state; and after defrosting is completed, the exhaust hole assembly is in an open state, and hot air in the freezing fan cover is exhausted through the exhaust holes. According to the exhaust mechanism, heat exchange between heat generated by the defrosting heater and air in the compartment is blocked, the influence of heat brought by defrosting on the temperature in the compartment can be reduced to the minimum, more electricity is saved, and environmental protection is facilitated.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to an exhaust mechanism, a refrigerator including the exhaust mechanism, and an exhaust control method of the refrigerator. Background technique [0002] After the refrigerator defrosts, it mainly produces defrosting water and defrosting heat. Among them, the defrosting water is mainly the water that melts after the frost is heated, and the defrosting heat is mainly the hot gas and residual heat generated during the operation of the defrosting heater. At present, the refrigerator only flows out the defrosting water through the defrosting drainage hole at the bottom of the refrigerator, but the influence of the defrosting heat generated during the defrosting period on the temperature balance of the cabinet is ignored. [0003] At present, all air-cooled refrigerators in the industry are facing the following problems: After the air-cooled refrigerator defrosts, because the defro...
