A washing machine according to an embodiment of the present invention will be described in detail below with reference to FIGS. 1 to 5.

The washing machine according to an embodiment of the present invention may include a clutch 110, a drain valve 120, and a driving device 130.

The clutch 110 is the heart of the washing machine and is a key component of the washing and dehydrating of the washing machine. The clutch 110 has a washing state and a dehydrating state during operation. When the clutch 110 is in the washing state, the dehydrating shaft and the dewatering bucket thereon are both Can not rotate, the motor drives the pulsator shaft and the pulsator on the pulsator shaft to rotate, thereby achieving washing or rinsing of the laundry; when the clutch 110 is in the dehydrated state, the motor drives the dehydration shaft and the dewatering bucket on the dewatering shaft to rotate, thereby completing the pair Dehydration of clothing.

As shown in FIG. 1, the clutch 110 is coupled to the clutch lever 111, and the clutch lever 111 is rotatable about the center of rotation of the lever. By controlling the rotation of the clutch lever 111, the clutch 110 can be switched between the washing state and the dehydration state.

It should be noted that when the clutch 110 is in the dehydrated state, the drain valve 120 on the washing machine should be opened to allow water generated during dehydration to be discharged from the washing machine. The drain valve 120 and the clutch lever 111 are connected by an intermediate connecting member, and the clutch lever 111 can control the drain valve 120 to open.

That is, the clutch lever 111 can control both the operating state of the clutch 110 and the operating state of the drain valve 120. In a specific example of the present invention, the clutch lever 111 can simultaneously control the operation of the clutch 110 and the drain valve 120. The state allows the operating state of the drain valve 120 to cooperate with the operating state of the clutch 110 to ensure that the washing machine is functioning properly.

The driving device 130 is arranged to drive the clutch lever 111 to rotate about the center of rotation of the lever, and when the clutch lever 111 is rotated until the clutch 110 is in the dehydrating position, the clutch lever 111 passes through the intermediate connecting member (for example, the drain valve wire 121) Driving the drain valve 120 to open the drain, where the washer 110 is in the dewatering position In the dehydration mode.

That is, the driving device 130 can simultaneously control the clutch 110 and the drain valve 120, and simultaneously control the drain valve 120 to open the drain when the control clutch 110 is in the dehydrated state, so that water generated during dehydration can be discharged from the washing machine.

According to the washing machine of the embodiment of the present invention, the driving device 130 can control the drain valve 120 to be opened for draining while the clutch 110 is in the dehydration position, without using two motor tractors, which simplifies the structure of the washing machine, at least at a certain time. To a lesser extent, the cost of the washing machine.

In some embodiments of the present invention, as shown in FIGS. 2 to 5, the driving device 130 includes a substrate 131 and a driving block 132. The substrate 131 is rotatable about a substrate rotation center and the driving block 132 is offset from the substrate rotation center line. That is, the driving block 132 is eccentrically disposed, and the driving block 132 is rotatable about the substrate rotation center line. Optionally. The substrate 131 is a cam, and the driving block 132 is disposed at an edge of the cam.

The driving block 132 on the substrate 131 can abut against the clutch lever 111. When the substrate 131 rotates, since the driving block 132 is eccentrically disposed on the substrate 131, the position of the driving block 132 is inevitably fixed and offset. Then, the driving block 132 can drive the clutch lever 111 to rotate.

The substrate 131 can be rotated clockwise or counterclockwise. In a specific example of the invention, the substrate 131 is rotated clockwise.

It is to be understood that the washing machine in accordance with an embodiment of the present invention further includes a drive motor 140 that is coupled to the substrate 131 and that is used to drive the substrate 131 to rotate.

Optionally, the intermediate connector is a drain valve cable 121. That is to say, the intermediate connector can only be subjected to tension and cannot withstand pressure. In other words, the clutch lever 111 can only be opened by pulling the drain valve 120 through the intermediate link, and the drain valve 120 cannot be closed by the intermediate link, and the closing of the drain valve 120 can be achieved by its own elastic member.

Specifically, the distance of the drain valve wire 121 from the first end 111a of the clutch lever 111 is smaller than the distance from the second end 111b of the clutch lever 111, wherein the first end 111a is the driving end of the driving device 130 driving the clutch lever 111. The second end 111b is a rotating end of the clutch lever 111 that rotates about the center line of the lever rotation. Alternatively, the clutch lever 111 is elongated.

In some embodiments of the invention, the washing machine further includes a resilient retaining member (not shown) that resiliently engages the clutch lever 111 to apply to the clutch lever 111 an elastic force that is maintained in the initial position. Optionally, the elastic retaining member is a torsion spring.

In other words, at the end of the dehydration of the washing machine, the clutch lever 111 can be quickly returned by the torsion spring to cause the clutch 110 to enter the initial state (ie, the washing state) from the dehydrated state, at which time the washing machine can inject water into the washing tub to Rinse the clothes or stop working directly.

The working work of the washing machine in accordance with an embodiment of the present invention will be described in detail below.

As shown in FIG. 2, the driving block 132 on the substrate 131 is located at point A when the washing machine performs the washing operation. At this time, the driving block 132 abuts on the clutch lever 111, the drain valve 120 is closed, and the clutch lever 111 is closed. The position corresponds to the washing operation state of the clutch 110; when the washing operation is completed, the washing machine control board issues a command for dehydration to the driving motor 140, and the driving motor 140 drives the substrate 131 to rotate clockwise until the driving block 132 on the substrate 131 moves to the position of FIG. B point stops, at this time, the clutch lever 111 rotates to switch the working state of the clutch 110 to the dehydration working state, and the clutch lever 111 opens the drain valve 120 through the drain valve wire 121 to start drainage; through the control of the washing machine control panel, the row is discharged. After the water is finished, the washing machine dewatering bucket performs a dehydrating operation; after the dehydration is completed, the washing machine control board gives a command to the driving motor 140, and the driving motor 140 drives the substrate 131 to start clockwise rotation, when the driving block 132 on the substrate 131 rotates to the point C1 of FIG. At this time, since the driving block 132 is beyond the length of the clutch lever 111, the clutch lever 111 is driven by the self-torsion spring. The speed is restored to point A, and the entire cycle is completed.
