washing machine touch button

Abstract

The invention discloses a touch button of a washing machine. The touch button comprises a sensitive button for sensing human electric charge as well as a circuit control board in communication connection with the signal output end of the sensitive button, wherein the sensitive button and the circuit control board are in communication connection through a sensitive spring; a base is fixedly mounted on the control circuit board; one end of the sensitive spring penetrates through the base, and is inserted on the circuit control board, and the other end of the sensitive spring is connected with the sensitive button; a front control board of the washing machine is connected to the end, far away from the sensitive spring, of the sensitive button. The touch button of the washing machine is simple in structure and reliable in mounting, stable connection of the sensitive spring and the circuit control board can be ensured through the base, the displacement can be avoided before and after welding, the button can be sensitive, and the base and the circuit control board are clamped and can be disassembled.

Description

technical field [0001] The invention relates to a washing machine control device, in particular to a washing machine touch button. Background technique [0002] The existing touch button device is separated from the circuit control board and the touch button board, and the touch button board is pasted on the front control board of the washing machine, and the signal line is used for communication in the middle to realize the touch button function. [0003] However, the above-mentioned touch buttons have many defects: there are potential safety hazards, and the signal line connector needs to be inserted in place to ensure smooth communication; because the touch button board needs to be pasted on the front control board of the washing machine, the touch button board may fall off after long-term use and cause The keys are not sensitive; the cost of signal lines and touch key boards needs to be increased. [0004] Based on the above problems, a new type of touch button is now p...

Problems solved by technology

[0003] However, the above-mentioned touch buttons have many defects: there are potential safety hazards, and the signal line connector needs to be inserted in place to ensure smooth communication; because the touch button board needs to be pasted on the front control board of the washing machine, the touch button board may fall off after long-term use and cause The keys are not sensitive; need to increase the cost of signal lines and touch key boards

[0004] Based on the above problems, a new type of touch button is now proposed, including a shell, an induction body, and a PCB control board. Insert the pins into the circuit control board and solder them. However, connecting the circuit control board and the spring through the pins on the spring does not guarantee a reliable connection. Displacement is likely to occur during welding or use, resulting in unreliable welding and key failure. Case
