Problems solved by technology

[0003] However, since the above-mentioned several button parts are connected into one body through the button connecting part, when the user operates, it is easy to form a linkage between adjacent buttons, resulting in misoperation.
In addition, when painting or maintenance replacement, it must be painted or completely replaced at the same time. When one of the buttons is poorly painted or needs to be replaced, this will undoubtedly increase the defective rate of the product and the cost of maintenance and replacement.

Embodiment Construction

[0022] refer to figure 1 , is a three-dimensional exploded schematic view of the key assembly 1 according to a specific embodiment of the present invention. As shown in the figure, the button assembly 1 includes a button 2 and a body 3, the button 2 includes a button part 4 for the user to press to input instructions, a base part 5 extends from one end of the button part 4, and the base part 5 When the user presses the button part 4, it can generate elastic deformation by its own elasticity.

[0023] For the convenience of understanding the present invention, in this embodiment, the assembly direction of the key assembly is defined as direction A, as shown by the arrow in the figure. to combine image 3 As shown, a buckle device 6 extends from the body 3 in a direction opposite to the assembly direction A, and a free end of the buckle device 6 is provided with a hook. further combined figure 2 As shown, an end 8 extends downward from the end of the base 5 away from the bu...

Abstract

The invention relates to a key component and a household electric appliance which uses the key component, the key component comprises keys and a body, the keys comprise key parts and base parts which are extended out of one ends of the key parts, a snap-fit device is extended out of the body along the reverse direction of the assembly direction, a card slot is arranged at the position which is positioned below the base parts and corresponding to the snap-fit device, and the snap-fit device is snap fitted in the card slot in a sliding manner. The usage of the sliding manner allows the assemblyto be more convenient, if one of the keys is damaged, only the key needs to be alone replaced; furthermore, as any key has the independent design relative to the adjacent keys, a user can not touch the adjacent keys during the operation, thus effectively avoiding the misoperation of the user.

Description

【Technical field】 [0001] The invention relates to a key assembly applied to a control panel for control and operation and a household appliance using the key assembly. 【Background technique】 [0002] In household electrical appliances, such as washing machines, refrigerators, microwave ovens, stoves, range hoods, etc., buttons are mostly used for operation and control. Usually, a control panel is provided at an appropriate position of the household appliance facing the user to facilitate the user's operation. The control panel is generally provided with switches or program control buttons and a display screen for displaying the working status or other working parameters. Press the button part of the button to operate. A circuit board is also installed in the control panel, and several electronic components, such as mechanical touch switches, are welded on the circuit board. When the user presses the button part of the button, the button part touches the mechanical touch s...
