Door of cold-storage and freezing device and cold-storage and freezing device

Abstract

The invention relates to a door of a cold-storage and freezing device and the cold-storage and freezing device. The door comprises a panel used for forming the front portion of the door, a display control assembly with a display touch control function, and a door foaming assembly used for forming the rear portion of the door. An accommodating cavity for accommodating the display control assembly, an air inlet duct and an air outlet duct are defined between the door foaming assembly and the panel, and the air inlet duct and the air outlet duct enable the accommodating cavity and the environment space to communicate. The display control assembly is accommodated in the accommodating cavity, an air inlet fan is arranged in the air inlet duct and is controlled to start when the humidity in the space where the display control assembly is located reaches a preset second humidity threshold value, and thus environment space is promoted to flow to the accommodating cavity through the air inlet duct. The door can effectively dissipate heat, and condensation on the display control assembly is prevented. The cold-storage and freezing device comprises a box and the door, and the door is directly or indirectly connected to the box so as to open and / or close at least part of a storage space.

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
