Horizontal type frostless refrigerator and control method thereof

Abstract

The invention discloses a horizontal type frostless refrigerator and a control method thereof, and relates to the technical field of refrigeration equipment. The horizontal type frostless refrigeratorcomprises a refrigerator box body, a refrigeration assembly including a fin evaporator, a fan set, a compressor and a fan cover is arranged in the refrigerator box body, the fan set comprises a firstfan fixedly arranged in a cavity in the fan cover and second fans which are fixedly arranged on the inner wall of the a refrigerator door and the other two inner side walls of the refrigerator box body, a first temperature sensor is arranged on the inner side wall, opposite to the mounting face of the fin evaporator, in the refrigerator box body, and a second temperature sensor is arranged on thefin evaporator. The fans are used for reinforcing turbulent flow in the refrigerator, the cold amount can be transmitted to the side, away from the evaporator, of the refrigerator, the temperature uniformity is improved, through primary judgment whether objects stacked in the refrigerator are too many or not, all the fans are started according to needs, the temperature uniformity is improved, theair flue structure in a foaming layer is removed, and mounting and manufacturing are facilitated.

Description

technical field [0001] The invention belongs to the technical field of refrigeration equipment, and in particular relates to a horizontal frost-free refrigerator and a control method thereof. Background technique [0002] As a convenient refrigeration tool, the horizontal freezer is widely used in commercial and household fields. In order to solve the disadvantages of serious frosting of direct-cooling horizontal refrigerators, by referring to the principle and structure of frost-free refrigerators, a utility model patent with application number CN201720145026.4 proposes a horizontal frost-free air-cooled refrigerator, through the design of fan cooling structure , to achieve the frost-free effect of the freezer, but because the freezer is a stacked storage, when there are many items in the room, in order to ensure that the cooling capacity can be sent to the end of the air-cooled freezer away from the evaporator, it is necessary to install air supply in the foam layer The a...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a horizontal frost-free freezer and its control method. By installing a finned evaporator, a fan group, and a temperature sensor in the freezer box, the fan is used to strengthen the internal disturbance of the freezer, so that the cold energy is transferred to the freezer. The side farther away from the evaporator improves temperature uniformity. By initially judging whether there are too many items accumulated inside the freezer, all fans are turned on according to demand, which solves the problem of high energy consumption when fans are often turned on, uneven temperature rise, and air ducts in the foam layer. The structure takes up space and is inconvenient to install and manufacture
