Embodiment Construction

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0041] Refrigeration equipment such as refrigerators and freezers are household appliances that are often used in people's daily life. They can ensure that the stored food does not deteriorate within a certain period of time, which brings great convenience to people's lives. For example: Air-cooled refrigerators are the mainstream refrigerators in the market at present. They use evaporators to cool the air, and send the obtained cold air through air ducts into refri...

Abstract

The invention discloses a refrigeration device, a control device and a control method thereof, and relates to the technical field of refrigeration, so as to ensure that the temperature fluctuation range of a refrigeration compartment is reduced during the defrosting process of an evaporator by a defrosting device, and the energy consumption of defrosting is reduced. The air duct assembly included in the refrigeration equipment includes a controllable shielding unit arranged at the air inlet of the fan, which includes a rotating cover and a guide structure. The guiding structure includes an air guide bottom shell, an annular guide rail arranged on the air guide bottom shell, and a limit baffle arranged on the ring guide rail. The limit baffle is used to control the maximum rotation angle of the rotating cover. The rotating cover rotates in the ring-shaped guide rail, so that the controllable shading unit can be switched between the wind-shielding state and the wind-guiding state. The refrigeration equipment provided by the invention is used in food preservation.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a refrigeration device, a control device and a control method thereof. Background technique [0002] Air-cooled refrigerator is a kind of refrigerator that uses air for cooling. Its refrigeration principle is to use the built-in evaporator to directly cool the air flowing through the built-in evaporator, so that the air temperature is lowered, and the obtained cold air is blown into the inside of the refrigerator to achieve the purpose of refrigeration. Purpose. [0003] After the built-in evaporator of the existing air-cooled refrigerator is refrigerated and frosted, the heating wire is generally used to heat the evaporator to defrost the evaporator, so that the user does not need to defrost, which brings great convenience to the user. However, the hot air produced by heating the evaporator with the heating wire will directly enter the freezer compartment, causing tempera...
