Description

Technical Field

[0001] The invention relates to the technical field of display panels, in particular to a moisture-proof integrated control display panel. Background Art

[0002] Thermostats play an important role in existing freezers. According to the temperature changes in the working environment, physical deformation occurs inside the switch, thereby producing certain special effects, a series of automatic control elements that produce conduction or disconnection actions, or transmit the temperature to the temperature controller through the temperature protector. The temperature controller issues a switch command to control the operation of the equipment to achieve the ideal temperature and energy-saving effect.

[0003] The main-variator-display integrated board refers to a control board that integrates the compressor inverter board, electronic display control board and mechanical temperature controller control board. Since it is connected to the display panel, it needs to be installed on the outer shell of the freezer for easy control. At present, when the temperature control panel of the freezer is in normal use and is splashed with water, the water will flow along the outer surface of the freezer to the inside of the temperature control panel, and then flow to the electronic devices along the inside of the temperature control panel. After the main-variator-display integrated board structure is flooded, it is easy to short-circuit and cause a fire, posing a safety hazard.

[0004] Patent publication number CN105222512B discloses a waterproof structure for a refrigerator thermostat panel. In the patent, a waterproof groove is arranged around the edge of the inner frame in the embedded box, and the outer flange of the temperature control panel is embedded in the waterproof groove. Even if water vapor or water droplets enter the waterproof groove, they can flow out along the surface of the groove to the lower area, thereby ensuring that the back of the thermostat panel with a circuit board installed is dry.

[0005] By comparing with the existing technology, the following defects are found: 1. The panel has poor waterproof performance; 2. There are buttons on the panel of the main variable display integrated board. Frequent pressing can easily cause the edge to warp, and the waterproof sealing ring is usually set on the outside, which can easily affect the sealing effect after warping; 3. Pressing too many times will cause the edge structure to loosen; 4. There are many components in the main variable display integrated board, and the heat is serious. Summary of the invention
