Door for refrigerating and freezing device and refrigerating and freezing device

Abstract

The invention relates to a door for a refrigerating and freezing device and the refrigerating and freezing device. The door comprises a panel serving as the front portion of the door, a display control assembly used for providing the display touch control function, a door foaming assembly serving as the rear portion of the door, and a heat dissipation waterproof cover arranged on the top of the door foaming assembly. A containing cavity used for containing the display control assembly and an air exhaust flue upwards extending from the containing cavity to the top of the door foaming assembly are defined between the door foaming assembly and the panel. The top of the door foaming assembly is provided with a water collection tank and an air outlet communicating with the air outlet exhaust flue, and the water collection tank is open upwards. The heat dissipation waterproof cover covers the water outlet in the vertical direction and is configured to enable the air outlet to communicate with the water collection tank so that heat in the containing cavity can sequentially pass through the air exhaust flue, the air outlet and the water collection tank and be dissipated to the environment space. The refrigerating and freezing device comprises a refrigerator body and the door. The door is directly or indirectly connected to the refrigerator body so as to open and / or close at least part of the storage space of the refrigerator body.

Description

technical field [0001] The invention relates to refrigeration and freezing technology, in particular to a door body for a refrigeration and freezing device and the refrigeration and freezing device. Background technique [0002] In order to meet people's needs, some existing refrigerators are provided with display control components with a touch display function. In order to facilitate the user's operation, the display control components are generally arranged on the door body of the refrigerator. The door body of the refrigerator is generally a thin-plate-shaped member, and there must be an accommodation cavity for installing the display control component in it. Therefore, the thickness of the foam layer of the door body opposite to the accommodation cavity is relatively thin, and part of the refrigerator storage space is cold. The amount is easy to leak into the accommodation cavity through the thinner foam layer. At the same time, the accommodating cavity is a relativel...

AI Technical Summary

Problems solved by technology

At the same time, the accommodating cavity is a relatively closed space, and a large amount of heat generated by the display control components during operation cannot be effectively dissipated. As a result, there will be a junction between cold and heat in the accommodating cavity, resulting in condensation of the display control components. Furthermore, the display control components are easily damaged, seriously reducing the quality of the entire door body

[0003] In order to solve the problem of condensation, in the prior art, two methods are usually adopted: increasing the thickness of the foam layer or increasing the assembly gap between the display control component and the door body. However, this not only cannot dissipate the heat generated by the display control component well, It will also increase the thickness of the entire door body

In order to solve the heat dissipation problem, one existing method is to install a heat dissipation air duct in the door body that runs through the door body in the transverse direction. However, this heat dissipation air duct does not meet the waterproof and dustproof requirements of the refrigerator, and external water or dust can easily pass through. The heat dissipation air duct enters the inside of the door body, which will affect the performance of the display control components and even damage the display control components
