Embodiment 1

[0033] Such as Figure 1-5 As shown, a control panel 100 of a washing machine, the washing machine includes a circuit board 300 disposed inside the control panel 100 and a knob disposed on the circuit board 300, the knob includes a knob cap 200 that protrudes from the control panel 100 and is rotatable The control panel 100 includes a limiting structure for limiting the shaking of the knob cap 200 when the knob cap 200 is rotated, and the limiting structure is integrally formed or fixedly connected with the control panel 100 .

[0034] The knob also includes an encoder 202 arranged on the circuit board 300. The encoder 202 is provided with a shaft. One end of the knob cap 200 is connected to the shaft and the other end protrudes from the control panel 100. When the user turns the knob cap 200, the rotation of the knob cap 200 drives The rotating shaft rotates to realize the control of the washing machine, and the structure of the knob is not limited to the knob controlled by t...

Embodiment 2

[0060] Such as Figure 1-5 As shown, the present embodiment is a further limitation of Embodiment 1. The control panel 100 is provided with an opening 101 through which the knob passes. The knob includes a knob cap 200 and an encoder 202. A circuit board 300 is arranged inside the control panel 100, and the encoding The encoder 202 is installed on the circuit board 300, the side of the knob cap 200 facing the circuit board 300 has a mounting column 201, the side of the encoder 202 facing the control panel 100 has a rotating shaft, the mounting column 201 of the knob cap 200 passes through the opening 101 and The rotating shaft is connected, the user rotates the knob cap 200, and the rotation of the mounting column 201 drives the rotating shaft of the encoder 202 to rotate, and then the angular displacement or linear displacement is converted into an electrical signal to control the washing machine.

[0061] The entire limiting structure is a plate structure, a part is located ...

Abstract

The invention belongs to the field of washing machines, and in particular relates to a control panel of a washing machine and a washing machine. The washing machine includes a circuit board arranged inside the control panel and a knob arranged on the circuit board. For the rotating knob cap, the control panel includes a limiting structure for limiting the shaking of the knob cap when the knob cap is rotated, and the limiting structure is integrally formed or fixedly connected with the control panel. The beneficial effect of the present invention is that the limit structure is arranged on the control panel, the shaking of the knob is limited by the limit structure, the drift of the knob is reduced, and the user's hand feeling is improved. One-piece molding reduces the cumulative tolerance of the dimensional chain, makes the limit structure better, and reduces shaking and drifting during the rotation of the knob.

Description

technical field [0001] The invention belongs to the field of washing machines, and in particular relates to a control panel of the washing machine and the washing machine. Background technique [0002] Smart home appliances have become a new development trend, and are accepted and sought after by more and more users. As the direct operation part of human-computer interaction, the quality of the control panel directly depends on the quality of home appliances. As a household appliance that is frequently used in a family, the washing machine has higher and higher requirements from users. [0003] The control panel on the washing machine is mostly independently installed on the front upper part or the upper part of the washing machine. The inner side of the control panel is provided with a circuit board. At present, users have higher and higher requirements on the control panel, not only requiring beautiful appearance and convenient operation, but also further improving the pe...
