Dew prevention structure of refrigerator door beam

Abstract

The invention belongs to the technical field of electric refrigerators in electric equipment, and particularly relates to a dew prevention structure of a refrigerator door beam. The dew prevention structure comprises a middle slab (3) of a door and a condensing dew prevention pipe (1) arranged between the middle slab (3) of the door and the interior of a refrigerator, wherein a heat storage device (2) is arranged between the middle slab (3) of the door and the condensing dew prevention pipe (1) so as to absorb and store the heat generated by the condensing dew prevention pipe (1) and transfer the stored heat to the middle slab (3) of the door. According to the invention, too high temperature of the middle slab in the boot process of a compressor is reduced on the premise of non-condensation of the middle slab of the refrigerator door; and the inflection point of condensation appeared on the middle slab is overcame and the leakage of heat from the middle slab to a refrigeration compartment is decreased.

Description

technical field [0001] The invention relates to the technical field of refrigerators for household appliances, in particular to a refrigerator door beam anti-dew structure. Background technique [0002] At present, the anti-dew structure of the door beam of the refrigerator generally uses the heat released by the high-pressure condensation pipe or the electric heating wire to increase the temperature of the door beam so that it is not lower than the dew point temperature of the corresponding ambient humidity, so as to avoid the phenomenon of condensation in the door beam. Among them, the high-pressure condensation pipe of the refrigeration system is used to prevent dew structure, such as figure 1 In the middle, the condensation anti-dew pipe 1 is in direct contact with the door beam plate 3. When the compressor is turned on, the temperature of the door beam plate is relatively high. In a high temperature environment, it can be as high as more than 70 degrees, which has serio...

Problems solved by technology

Among them, the high-pressure condensation pipe of the refrigeration system is used to prevent dew structure, such as figure 1 In the middle, the condensation anti-dew pipe 1 is in direct contact with the door beam plate 3. When the compressor is turned on, the temperature of the door beam plate is relatively high. In a high temperature environment, it can be as high as more than 70 degrees, which has seriously exceeded human contact. When the compressor is shut down, the temperature of the beam in the door may be lower than the dew point temperature of the environment at that time due to the leakage of the door gap, resulting in condensation in the beam in the door
