Embodiment 1

[0054] In this example, if Figure 1~6 As shown, a washing machine detergent box is provided, including a handle 100 and a box body 2, the rear side of the handle 100 is respectively connected to the main control board 8 of the washing machine and the box body 2, and the box body 2 is passed through the The main control board 8 is arranged in the washing machine on the rear side of the main control board 8 so that the detergent box can be pushed and pulled.

[0055] In this embodiment, the handle 100 is fixedly connected with the box body 2 to form a detergent box, and the detergent box is integrated on the main control board 8, so that the handle 100 is presented on the front side of the washing machine as a part of the main control board 8, In the present invention, a guide connection structure is added between the handle 100 and the main control board 8. When the detergent box is pushed into the washing machine, the guide connection structure will stably fix the handle 100 ...

Embodiment 2

[0074] The difference between this embodiment and embodiment 1 is:

[0075] In this embodiment, the guide column 1 includes an elastic hook 11 extending to the rear side of the handle 100. When the guide column 1 is plugged with the main control board 8, the elastic hook 11 is snapped into the main control board 8. The socket of 8 is set to generate pre-tightening force in the pulling-out direction of the detergent box, and the elastic hook 11 is arranged on the top surface of the guide column 1 .

[0076] In this embodiment, in addition to the function of positioning and guiding, the guide column 1 also has a structure that provides pre-tightening force for the insertion of the handle 100 and the main control board 8, that is, the elastic hook 11 is inserted into the main control board 8 on the guide column 1. When the control panel 8 is in place, the elastic hook 11 is elastically deformed and connected to the plug-in interface. When the detergent box is pulled, it is necess...

Embodiment 3

[0083] In this example, if Figure 7-12 As shown, a washing machine waterproof main control board is provided, including a decorative plate 3 located on the front side of the main control board 8 and a computer board box 9 located on the rear side of the main control board 8, and the computer board box 9 is provided with On the computer board, the decorative board 3 is provided with a button 5, the rear side of the button 5 passes through the main control board 8, and is in contact with the elastic pad 4 located on the front side of the computer board box 9, and pressing the button 5 makes the deformation elastic Pad 4 touches the control switch on the computer board.

[0084] In this embodiment, the corresponding positions of the decorative board 3, the main control board 8 and the computer board box 9 are provided with through holes for the installation and action of the button 5, wherein the through holes on the front side of the computer board box 9 are covered with elasti...

Abstract

The present invention relates to the technical field of laundry, in particular to a main control board of a washing machine, including a main control board, a computer board box arranged on the rear side of the main control board, and a computer board arranged in the computer board box, the computer board It is snapped into the inner side of the peripheral wall of the computer board box, and the outer side of the computer board box is provided with hanging ears, so that the electrical components of the main control board are arranged along the wiring of the hanging ears. The main control board of the washing machine provided by the present invention includes a computer board box provided with hanging ears and a clamping structure. On the one hand, the clamping structure simplifies the installation and disassembly of the main control board; The wiring arrangement of each electrical component provides greater convenience for installation and maintenance, and is suitable for popularization and use.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a main control board of a washing machine. Background technique [0002] The main control board of the washing machine contains a circuit board and a large number of other electrical components, and the components are connected by wires. Due to the narrow space inside the main control board of the washing machine, it is very unfavorable for regular wiring. In this case, the wires may be squeezed by the installation structure when installing the main control board and its accessories, causing the wire sheath to be damaged, resulting in a greater safety hazard. [0003] In addition, in order to stabilize the installation of some main control boards, metal parts such as screws are often used to fix the main control board with the washing machine body. Board installation stability. [0004] In view of this, the present invention is proposed. Contents of the invention ...
