Description

Refrigerator with a door

The invention is based on Chinese invention application CN202010632721.X (2020-07-01), the invention name: divisional application of refrigerators.

Technical Field

The invention relates to the technical field of refrigeration equipment, in particular to a refrigerator.

Background

Refrigerators have different environments and different storage requirements, and the temperature inside the refrigerator needs to be controlled to meet the corresponding control environment.

The existing refrigerator controller can be divided into three categories of mechanical temperature control, electronic temperature control and computer temperature control, wherein the mechanical temperature control can only qualitatively preset several levels of temperature, the function is extremely simple, and the temperature control precision is low. The electronic temperature control can realize continuous temperature setting and temperature control, and the temperature control precision is also improved; some overvoltage and undervoltage and time delay protection functions are correspondingly added, but the temperature control mode cannot be flexibly changed according to the requirements of users, and the energy-saving mode cannot be automatically selected. The computer temperature control has superior processing capacity, the refrigerator can run under the control of a program, and the temperature control mode can be flexibly changed according to the requirements of users. The computer temperature control method mainly comprises the steps of arranging a main hole plate in the refrigerator and intelligently controlling the refrigerator to work through the main hole plate.

At present, in most computer-controlled refrigerator products, a main control panel is installed on a rear plate at the back of a refrigerator body, a plastic control panel box is generally overlapped on the rear plate of a refrigerator body rear plate, sponge and adhesive tape are utilized to cover and seal the rear plate for foaming, a metal rear cover is covered outside the foamed rear plate, and the main control panel is installed in the control box. According to the installation mode, when water exists on the upper portion of the rear plate of the box body, the water can slide downwards from the rear plate of the box body and enters the control box along the gap between the rear plate and the cover plate, so that the main control plate can be short-circuited, and potential safety hazards are easily caused.

Disclosure of Invention

The invention aims to provide a refrigerator, which can effectively prevent water from entering a control box and ensure the normal use of a main control panel.

In order to solve the technical problem, the invention adopts the following technical scheme:

according to one aspect of the present invention, there is provided a refrigerator including a cabinet and an accommodating structure; an opening is formed in one side of the box body; the accommodating structure comprises a control box and a rear cover; the rear cover is fixed on the box body and closes the opening; the upper end of the rear cover penetrates through the opening and extends into the box body, and the top end of the rear cover is positioned above the opening; the lower end of the rear cover is positioned outside the box body; the control box set up in the medial surface of back lid, the control box with be formed with the holding chamber that is used for the holding control panel between the back lid.
