An anti-condensation heating device for refrigerators

Abstract

The invention provides a gelling-prevention heating device for a refrigerator. The refrigerator comprises a box body and a door body which is rotatably connected with the box body, wherein the heating device comprises a door rotating beam assembly vertically arranged on the door body; the interior of the door rotating beam assembly is a hollow chamber and a heater is arranged internally in the door rotating beam assembly; and the heater comprises an upper heater, a middle heater and a lower heater of which the power is sequentially and gradually increased from top to bottom. According to the gelling-prevention heating device disclosed by the invention, the gelling of the lower part of a refrigeration chamber can be effectively prevented, the heating time is shortened, and the energy consumption of refrigerator is reduced; moreover, line distribution process of the heater is comparatively simple, the operation is easy, and the security is high.

Description

technical field [0001] The invention relates to the technical field of refrigerating equipment, in particular to an anti-condensation heating device for a refrigerator. Background technique [0002] The French door and cross-door refrigerators currently on the market are generally designed with a door flip beam between the two refrigerator doors. Due to the limitations of the structure and materials, the local insulation performance is poor, and the surface temperature of this part is relatively high when the refrigerator is normally refrigerated. Low prone to condensation. In order to prevent condensation, an aluminum foil heater is generally pasted on its surface, and the surface temperature is raised by the aluminum foil heater to achieve the purpose of dew condensation. [0003] The heating device currently used on the door flip beam on the market, the power density of the aluminum foil heater inside (commonly known as the meter power), the meter power of each section i...

Problems solved by technology

The above two solutions have the following disadvantages: 1. The heating time of the electric heater is long, which increases the energy consumption of the entire refrigerator; 2. The temperature in the upper part of the refrigerator is relatively high during normal dew removal, especially near the door turning beam, which is not conducive to food preservation ;3. Due to the limitation of the space of the door beam, the shape of the lower end of the heater is complicated, the operation process is more troublesome, the efficiency is low, and the safety is poor.
