As described in the background art, there is a problem in that washing waste water is not completely discharged after washing is completed in a washing machine, and the remaining washing waste water may generate bacteria in the washing machine. Therefore, when the washing machine is fed with water again, clean washing water can be mixed with residual washing wastewater to cause secondary pollution to clothes, which not only influences the washing effect of the washing machine, but also influences the body health of a user.

In view of this, the embodiment of the present invention provides a washing machine having an isolation valve, in which the isolation valve is disposed at the drainage port of the washing tub and the first opening of the drainage device, so that the washing tub can be communicated with or isolated from the drainage device through the isolation valve. Specifically, under the condition that the isolation valve is in the first state, the first opening is opened, and the accommodating cavity and the water outlet of the washing barrel can be communicated; when the isolation valve is in the second state, the first opening is closed, and the accommodating cavity and the water outlet of the washing barrel can be blocked. Therefore, after the drainage program of the washing machine is finished, the residual washing wastewater in the drainage device can be isolated from the new washing water entering the washing barrel through the second state of the isolation valve, so that the secondary pollution caused by the mixing of the washing wastewater and the new washing water is avoided.

After the washing machine starts to work, the drainage device is closed, clean washing water enters the washing barrel, after the water level in the washing barrel reaches a preset water level, water feeding is stopped, and the washing machine starts to wash clothes. After washing, the washing machine needs to discharge washing wastewater in the washing tub, thereby dehydrating the laundry. In the dehydration process, the drainage device is opened, and the washing wastewater is discharged to the outside through the drainage device.

The washing machine in the embodiment of the present application refers to a widely used household appliance for washing laundry by using mechanical action of electric energy generation, and includes a machine body and a washing tub. Currently, there are several types of washing machines: the present invention relates to a drum-type washing machine, an agitator-type washing machine, a pulsator-type washing machine, and a jet-type washing machine.

Referring to fig. 1 and fig. 2, fig. 1 is a front view of a washing machine 1 according to an embodiment of the present invention, and fig. 2 is a back view of the washing machine 1 according to an embodiment of the present invention. The washing machine may include: a machine body 10, a washing tub 20, a blower 30 (the blower 30 is not shown in fig. 1 and 2), a drainage device 40, and a controller 50 (the controller 50 is not shown in fig. 1 and 2).

In some embodiments, the body 10 is used to protect electrical components inside the washing machine, and to close the contact passage between the inside and the outside of the washing machine, thereby preventing the electrical components from being damaged. Illustratively, the body 10 may be rectangular as shown in fig. 1.

In some embodiments, the washing tub 20 is disposed in the machine body 10, and a space is left between the washing tub 20 and the machine body 10 for movement of the washing tub 20 and for placement of electrical components, and the washing tub 20 is used as a carrier for containing laundry, and is used for washing, dewatering, and the like of the laundry.

In some embodiments, the washing tub 20 may include an inner tub and an outer tub, the inner tub being disposed in the outer tub.

For example, the inner tub may be used to wash laundry, and the outer tub may serve as a tub, wherein a sidewall of the inner tub may be provided with dehydration holes. When the washing machine is in a washing state, the water level in the inner tub is consistent with that in the outer tub, and when the washing machine is in a dehydrating state, the water in the outer tub and the water in the inner tub are sequentially discharged to the outside.

In some embodiments, the washing tub 20 is provided with a drain port for discharging the washing wastewater in the washing tub 20 to the outside.

For example, the drain port may be disposed at the bottom of the outer tub, and the drain port is connected to the inlet of the drain device.

In some embodiments, the blower 30 is disposed in the housing 10 and has an air outlet for sending a high-pressure air flow into the accommodating cavity, so that the residual water in the accommodating cavity is blown to the outside through the second opening 4012.

In some embodiments, as shown in fig. 3, the drainage device 40 may include: a housing 401 and an isolation valve 402.

In some embodiments, as shown in fig. 4, the housing 401 includes a receiving chamber and a first opening 4011, a second opening 4012, and a third opening 4013 in communication with the receiving chamber.

The first opening 4011 serves as an inlet of the drain device 40, communicates with a drain port of the washing tub 20, and is used for flowing the washing water in the washing tub 20 into the receiving cavity of the drain device 40.

The second opening 4012 serves as an outlet of the drain device 40, communicating with the outside, for discharging the washing water in the receiving chamber to the outside.

Optionally, a first valve is disposed at the second opening 4012, and the first valve includes a valve rod for opening or closing the second opening 4012.

Optionally, the drainage device 40 further comprises a retractor connected to the first valve for driving the valve rod to move to open or close the second opening 4012.

As a possible implementation manner, when the first valve is in the open state, the accommodating chamber is communicated with the outside, and when the first valve is in the closed state, the accommodating chamber is isolated from the outside.

As shown in fig. 4, the third opening 4013 is connected to an air outlet of the blower 30, and is used for allowing the wind generated by the blower 30 to flow into the accommodating chamber of the drain device 40.

As a possible implementation, when the second valve is in the open state, the air outlet of the blower 30 is in communication with the housing chamber, and when the second valve is in the closed state, the air outlet of the blower 30 is isolated from the housing chamber. Thus, after the washing tub is isolated from the drainage device 40, the washing wastewater remained in the drainage device 40 can be blown out to the outside by the action of the blast air 30, thereby reducing the bacterial growth in the washing machine.

Alternatively, the washing machine 1 may further include: a first pipeline, a second pipeline and a third pipeline.

As a possible implementation, the first opening 4011 serves as an inlet of the drain device 40, and is communicated with the drain port of the washing tub 20 through the first pipeline. The second opening 4012 serves as an outlet of the drain 40 and communicates with the outside through a second line. The third opening 4013 is connected to an air outlet of the blower 30 through a third pipe.

For example, the first pipeline may be a groove disposed on the machine body 10, or may be a pipe disposed in the machine body 10, for example, the pipe may be a hose, a bellows, or the like.

In some embodiments, an isolation valve 402 is disposed at the first opening 4011 of the receiving chamber to open or close the first opening 4011. Alternatively, when the isolation valve 402 is in the first state, the first opening 4011 is opened to communicate the washing tub 20 with the receiving chamber of the drain 40. When the isolation valve 402 is in the second state, the first opening 4011 is closed to isolate the washing tub 20 from the receiving chamber of the drain 40.

As can be seen from the above embodiments, by providing the isolation valve 402 at the drain port of the washing tub and the first opening 4011 of the drain 40, the washing tub can be communicated or isolated from the drain 40 by the isolation valve 402. In this way, after the drainage procedure of the washing machine is finished, the residual washing wastewater in the drainage device 40 can be isolated from the new washing water entering the washing tub by the second state of the isolation valve 402, so as to prevent the washing wastewater from mixing with the new washing water to cause secondary pollution.

In some embodiments, isolation valve 402 may comprise a ball valve as shown in FIG. 5, which has a through hole therein and which is rotatable. As shown in fig. 6, when the isolation valve 402 is in the first state, the through hole of the globe valve communicates the first opening 4011 with the receiving chamber. As shown in fig. 7, the through bore of the globe valve isolates the first opening 4011 from the receiving chamber when the isolation valve 402 is in the second state.

Alternatively, as shown in fig. 8 and 9, the drainage device 40 may further include: an isolation valve connecting shaft 404, an isolation valve motor 405, an isolation valve fixing member 406, an isolation valve motor fixing member 407, a filter 408, a filter fixing member 409, and a drain pump 410. Wherein,

the isolation valve connecting shaft 404 is connected with a ball valve.

Optionally, the isolation valve motor 405 is a stepper motor. When the isolation valve 402 is in the first state, the through hole of the globe valve communicates with the first opening 4011, and the isolation valve motor 405 rotates the isolation valve 402 by 90 ° by driving the isolation valve connecting shaft 404, so that the through hole of the globe valve is isolated from the first opening 4011, thereby placing the isolation valve 402 in the second state. When the isolation valve 402 is in the second state, the through hole of the globe valve is isolated from the first opening 4011, and the isolation valve motor 405 rotates the isolation valve 402 by 90 ° by driving the isolation valve connecting shaft 404, so that the through hole of the globe valve can communicate with the first opening 4011, thereby placing the isolation valve 402 in the first state.

And an isolation valve fixing member 406, which is disposed outside the housing 401 at a side close to the first opening 4011, is connected to the housing 401, and is used for fixing the isolation valve 402.

And a filter 408 disposed in the receiving chamber of the drain device 40 for filtering impurities of the washing water in the receiving chamber to prevent the second opening 4012 from being blocked.

The filter 408 is used to filter out fine particles (generally, thread waste, fiber, plastic, etc. having a size of 5mm or less) in the washing wastewater discharged from the washing machine 1.

Illustratively, when the isolation valve is in the first state, the washing wastewater flows into the accommodating cavity of the drain device 40 through the drain port of the washing tub 20 via the first opening 4011. Fine particles (generally, thread waste, fiber, plastic, etc. having a size of 5mm or less) in the washing wastewater discharged from the washing machine 1 are filtered by the filter 408, and then discharged to the outside through the second opening 4012.

Optionally, housing 401 further includes a fourth opening 4014, and filter holder 409 is disposed at fourth opening 4014 for holding filter 408.

As a possible implementation manner, the filter fixing member 409 is provided with a connection hole, and the drain device 40 can be fixed on the body 10 of the washing machine 1 by a screw matched with the connection hole.

In some embodiments, a drain pump 410 is connected to the housing 401, the drain pump having an inlet end and an outlet end at the receiving chamber, wherein the inlet end is communicated with the receiving chamber, and the outlet end is communicated with the second opening 4012 for discharging the washing water in the receiving chamber of the drain device 40 to the outside.
