Abstract

The invention discloses a household appliance, a touch panel and a key. The household appliance comprises a circuit board, a conductive shell, a light source and a dodging sheet, the shell comprises abottom surface and a top surface which are opposite to each other, and the shell is provided with an containing cavity penetrating through the bottom surface and the top surface. One end of the bottom surface of the shell is arranged on the circuit board and is electrically connected with the circuit board, the light source is installed on the circuit board, is contained in the containing cavityand is electrically connected with the circuit board, and the dodging sheet is arranged at one end, close to the top surface, of the shell, is contained in the containing cavity and can uniformly guide the light emitted by the light source out of the key. The shell in the key has conductivity, so that the key can determine whether a user touches and operates the key or not according to the changeof an electric signal on the shell, and additionally the key can control the light source to work according to the change of the electric signal on the shell. According to the embodiment of the present invention, when the key is touched and operated, the shell basically does not deform or generates smaller deformation, so that the shell does not deviate, and the reliability of the key is further improved.

Description

technical field [0001] The present invention relates to the field of electronic technology, and more specifically, to a button, a touch panel and a household appliance. Background technique [0002] Existing buttons used on household appliances generally use spring switches, and the springs in the spring switches are prone to positional deviation during use and when subjected to vibrations, thereby affecting the use of the spring switch and reducing the reliability of the household appliances.
