Problems solved by technology

[0004] The washing machine disclosed in the above-mentioned patent uses a motor to drive the washing door to open and close the washing machine door. However, since the solution adopted in this application is that the motor directly drives the door to rotate, when the washing machine is powered off, when the upper cover is manually opened , it is bound to drive the motor to rotate, which is not only laborious and difficult to open the upper cover, but also easily causes damage to the motor

Embodiment 1

[0033] This embodiment proposes an opening and closing mechanism for the upper cover of a washing machine, including a control device, a driving device, and a reduction device. The upper cover can be opened or closed driven by the output shaft of the reduction device. The input end of the reduction device connected to the drive unit. The opening and closing mechanism of the upper cover of the washing machine in this embodiment also includes a clutch device, the clutch device and the driving device are connected to the control device, and the clutch device is connected to the speed reduction device and the driving device. cooperate to engage or disconnect the transmission path between the driving device and the upper cover under the control of the control device.

[0034] The control device is preferably a computer board, and the driving device is preferably a motor. Under the control of the computer board, the motor drives the upper cover to open and close through forward and ...

Embodiment 2

[0038] Embodiment 2 is a preferred implementation of Embodiment 1.

[0039] Such as figure 1 , figure 2 Shown is the opening and closing mechanism of a washing machine top cover proposed in this embodiment, including a control device, a driving device 3, and a speed reduction device. The top cover can be opened or closed under the drive of the output shaft 21 of the speed reduction device. The input end of the deceleration device is connected with the drive device 3, and also includes a clutch device, the clutch device and the drive device 3 are connected with the control device, and the clutch device is connected with the deceleration device and the The driving device 3 cooperates, and under the control of the control device, the transmission path between the driving device 3 and the upper cover is engaged when the power is turned on, and the connection between the driving device 3 and the upper cover 1 is disconnected after the power is turned off. transmission path betwe...

Embodiment 3

[0044] Such as Figure 4 Shown is an opening and closing mechanism of a washing machine proposed in this embodiment. The difference between the opening and closing mechanism in this embodiment and the second embodiment is that the clutch device in this embodiment is composed of a spline sleeve 25, an electromagnetic seat 41 and a spring 42, and the output shaft 22 of the driving device 3 or the The output shaft 22 of the speed reduction device is composed of two disconnected parts, both of which are provided with external splines and connected by spline sleeves. The electromagnetic seat 41 can attract the sliding movement of the spline sleeve 25; the electromagnetic seat 41 cooperates with the spring 42 to act on the spline sleeve 25 to engage or disconnect the connection between the two parts. power delivery.

[0045] The spline sleeve 25 in this embodiment is arranged on the output shaft 22 of the driving device 3, the output shaft 22 is composed of two parts that are disc...

Abstract

The invention discloses an opening and closing mechanism for an upper cover of a washing machine and the washing machine, comprising a control device, a driving device, a clutch device and a deceleration device. The upper cover is opened or closed under the drive of the output end of the deceleration device. The clutch device and the drive device are connected to the control device. The clutch device cooperates with the deceleration device and the drive device. Under the control of the control device, the transmission path between the drive device and the upper cover is engaged when the power is turned on. Disconnect the transmission path between the drive unit and the upper cover. The invention is provided with a clutch device. When the motor is powered off, the clutch device separates the motor and the deceleration device, so as to avoid driving the motor to rotate when the upper cover is manually opened, which is easy and convenient and will not cause the motor to rotate abnormally or be damaged. The mechanism also has the characteristics of small occupied space, compact structure, and high stability of opening and closing the upper cover.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to an opening and closing mechanism for an upper cover of a washing machine and the washing machine. Background technique [0002] Most of the washing machines on the market, especially the pulsator washing machines, require manual operation by the user to open and close the upper cover. In the ordinary washing process, the upper cover of the washing machine is usually opened by hand first, then clothes and washing liquid are added, then the upper cover is closed to start the washing machine program, and the upper cover is opened after washing to take out the clothes. In addition, it is necessary to open and close the upper cover of the washing machine for adjustment if the clothes are too eccentric during dehydration. [0003] Chinese Patent Document Publication No. CN1158923A discloses a novel device provided to a washing machine, which includes: opening and closing the door of th...
