Key water-proof structure of washing machine

Abstract

The invention discloses a button waterproof structure of a washing machine; the button waterproof structure comprises a control panel on the top of the washing machine, a decoration board above the control panel and a computer board component below the control panel; the control panel is provided with a plurality of sets of buttons and display areas corresponding to a computer board circuit; the computer board component comprises a circuit board with a display screen, a computer board box below the computer board and used to support the computer board, and a box cover plate above the computer board and used to protect the computer board; the button waterproof structure is characterized in that the lower bottom surface of the decoration board and the upper plane of the box cover plate are provided with an upper lug and a lower lug corresponding to the display areas, so as to protect a water permeability resistant component of the display screen; waterproof mechanisms used to prevent water from being leaked from the gaps of button holes are arranged at the positions of corresponding buttons of the decoration board and between the buttons and the box cover plate. The structure not only can ensure the production efficiency and does not greatly increase the production cost, but also can make sure the buttons have good touch feeling and the waterproof performance meets requirements.

Description

technical field [0001] The invention relates to a washing machine key, in particular to a washing machine key waterproof structure. Background technique [0002] Below the operation panel of the washing machine is the computer board. Since the washing machine is often used in an environment with high humidity, the phenomenon of short circuit and burning of the computer board due to water ingress often occurs. If waterproofing is not considered, water will flow from the decorative board. The button hole directly penetrates into the computer board, which may cause the computer board to be damaged by moisture. In traditional washing machines, the panel control box uses mechanical buttons. The disadvantage is that it is easy to cause poor button force or damage to the buttons after a long time, resulting in poor market and increased quality maintenance costs; at the same time, the structure of the traditional washing machine control panel adopts split type. Mechanical composite...

Problems solved by technology

If the structure is used for a long time, the sealing sleeve made of elastomer material will be deformed, and the water will slowly seep in because the water is stored in the gap, the waterproof effect is not good, and the water is stored in the key hole for a long time, and it is easy to breed bacteria
