Description

A kind of defrosting plate for refrigerator

technical field

The utility model belongs to the technical field of refrigerators, in particular to a defrosting plate for refrigerators.

Background technique

The air-cooled refrigerator solves the problem that the direct-cooled refrigerator needs artificial defrosting, but the air-cooled refrigerator needs the evaporator to defrost, and the defrosting time generally takes 20 to 40 minutes, which will cause the temperature of the compartment to rise.

After the defrosting of the air-cooled refrigerator is completed, there will be a certain amount of waste hot air on the top of the evaporator compartment. After the cooling fan is started, this part of the waste heat will be directly blown into the compartment, which will further increase the temperature of the already warmed compartment. The temperature fluctuation of the compartment is enlarged; therefore, a defrosting plate for a refrigerator is urgently needed to solve this problem.

Utility model content

The purpose of this utility model is to provide a defrosting plate for refrigerators, through the defrosting plate and the heat conduction pipe, the cooling capacity generated by the evaporator or the heat generated by the defrosting heater is transferred to the evaporator during refrigeration or when the evaporator is defrosted. It solves the problem of uneven heating of the evaporator when defrosting the existing air-cooled refrigerator, resulting in a long defrosting time and a sharp rise in the temperature of the compartment caused by the residual waste heat during cooling.

In order to solve the above-mentioned technical problems, the utility model is realized through the following technical solutions:

The utility model relates to a defrosting plate for a refrigerator, which comprises a refrigerator box body, an evaporator compartment is partitioned in the inside of the refrigerator box body by a partition plate; The bottom end of the refrigerator and the refrigerator box form a return air outlet; the evaporator bin is sequentially installed with a fan, an evaporator and a defrosting heater from top to bottom;

A defrosting plate is fixedly installed on the side of the evaporator bin away from the partition plate; and a number of vertically downward heat-conducting pipes are fixedly installed on the side of the defrosting plate close to the evaporator.

Further, the size of the defrosting plate is adapted to the side surface of the evaporator bin.

Further, the defrosting plate is fixedly installed on the top of the back of the evaporator bin.

The utility model has the following beneficial effects:

1. When the utility model defrosts the evaporator through the defrosting plate and the heat conducting pipe, the heat generated by the defrosting heater is rapidly conducted to the upper end of the evaporator, so that the evaporator is evenly heated, and the phenomenon that the upper part of the evaporator is cooled and the lower part is heated is avoided. occurs, improving the defrosting efficiency of the evaporator.

2. The utility model transfers the cooling capacity generated by the evaporator to the upper space of the evaporator bin during refrigeration through the defrosting plate and the heat conducting pipe, and absorbs the waste heat generated by the defrosting heater; it avoids the waste heat being blown after the fan is started. into the compartment, resulting in a rapid increase in the temperature of the compartment.

Of course, any product implementing the present invention does not necessarily need to simultaneously achieve all of the above-mentioned advantages.
