Problems solved by technology

[0003] However, most of the existing double-drum washing machines use two control panels to control the two washing drums respectively, the production cost is high, and the structure of the washing machine control panel is simple, and the user operation is complicated
In addition, the existing double-drum washing machine uses a control panel to control the two washing drums separately through buttons and other mechanical methods. setting

Embodiment approach

[0043] Mode 1, the selection control key includes one, which is shared by each washing device, and each time the selection control key is activated, a set of washing devices is switched and selected.

[0044] For example, a washing machine has two sets of washing devices, the first drum and the second drum. The original state of the selection control key is off. When the selection control key is activated for the first time, the first drum is selected by default. When the operation is activated again, it is switched to selected. When the second roller is activated again, it is switched to select the first roller, so that each time the operation is activated, the first roller and the second roller are alternately selected in turn.

[0045] In this way, only one selection control key needs to be set on the control knob, the structure is more simplified, and the installation is more convenient.

[0046] Mode 2, the selection control keys include multiple ones corresponding to the w...

Embodiment 1

[0072] The selection control key of this embodiment is activated by touch, such as figure 1 and figure 2 As shown, the selection control key includes a touch film 108 and a connecting cable 109. The touch film 108 is connected to the printed circuit board 106 through the connecting cable 109. There are a plurality of touch points on the touch film 108, corresponding to the washing device respectively. .

[0073] Specifically, the touch film 108 is disposed close to the inner wall of the knob upper cover of the selection knob. There are two touch points on the touch film 108, and the two touch points are respectively arranged on the underside of the first partition 102 and the second partition 107 of the upper cover of the knob, corresponding to the first roller and the second roller respectively.

[0074] When the user touches the first partition 102 on the top cover of the knob, the touch point on the lower side of the first partition 102 is activated when the touch is sen...

Embodiment 2

[0078] The selection control key of this embodiment is activated by touch, such as image 3 and Figure 4 As shown, the selection control key includes a plurality of touch-sensitive sheets corresponding to the washing device, and springs, and each touch-sensitive sheet is connected to the printed circuit board 106 through the spring. The touch-sensitive sheet is kept away from the peripheral edge of the knob upper cover by a certain distance to prevent the touch key response inside the knob from being accidentally triggered during the rotation of the knob.

[0079] Specifically, the touch-sensitive sheet includes a first touch-sensitive sheet and a second touch-sensitive sheet, the first touch-sensitive sheet is set close to the inner wall of the first partition 102 of the upper cover of the knob, and the first touch-sensitive sheet is connected to the printed circuit board through the first spring 112 circuit board. The second touch-sensitive piece is arranged close to the ...

Abstract

The invention provides a selection control rotary knob for a washing machine, and the washing machine. The washing machine comprises at least two sets of washing devices capable of operating independently and one set of control panel shared by the washing devices; the selection control rotary knob comprises a selection control key which is used for selecting each washing device and a selection rotary knob which is shared by each washing device to select procedures; the selection control key is integrally arranged on the selection rotary knob; and the selection rotary knob is arranged on the control panel. The selection control rotary knob provided by the invention mainly aims at the washing machine with multiple sets of washing devices capable of operating independently, the selection control key for selecting the washing device is integrally arranged on the selection rotary knob for selecting the procedures, the washing device is selected by the selection control key, and the related procedure of the set of the washing device is selected by the section rotary knob, so that the aim that one set of washing procedures are shared by multiple sets of the washing devices is fulfilled, the structure of the control panel is simplified and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a selection control knob for washing machines and the washing machine. Background technique [0002] In modern life, every household is inseparable from the washing machine, and the washing machine has become a good helper in people's life. At present, there are more and more styles of washing machines, and their functions are becoming more and more powerful. With the increase of functions and styles, double-drum washing machines gradually appear in people's lives. The double-drum washing machine has two mutually independent washing tubs, and the user can choose to use any one of the washing tubs to wash the clothes, or choose to use the two washing tubs to wash the clothes separately. Therefore, the double-drum washing machine can wash more clothes at one time, avoiding repeated operations of the user and reducing the workload of the user; in addition, the double-drum ...
