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 invention relates to the technical field of washing machines, in particular to a waterproof main control panel of a washing machine. The waterproof main control panel comprises a decorative plateon the front side of the main control panel and a computer board box on the rear side of the main control panel. A computer board is arranged in the computer board box, the decorative plate is provided with a button, the rear side of the button penetrates the main control panel to contact with an elastic pad on the front side of the computer board box, and by pressing of the button, the elastic pad in deformation is enabled to contact with a control switch of the computer board. The waterproof main control panel comprises the computer board which is hermetically arranged through the elastic waterproof pad, the button structure is redesigned according to the integral structure to improve hand feeling of the button, and accordingly user experience is improved, and the waterproof main controlpanel is suitable for popularization and utilization.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a waterproof main control board of a washing machine. Background technique [0002] The main control board of the washing machine contains circuit boards and a large number of other electrical components, so the requirements for waterproofing are relatively high. The washing machine is often located in a relatively humid environment. Users may use wet hands to control and operate the washing machine panel. Due to the assembly of the main control board of the washing machine and the cabinet, and there are gaps between the button structure and the main control board, water vapor will enter Inside the main control board, the risk of damage to the circuit board and electrical components is increased. [0003] In view of this, the present invention is proposed. Contents of the invention [0004] The first purpose of the present invention is to provide a main control board...
