DETAILED DESCRIPTION OF THE INVENTION

[0019] The following is a detailed description of the embodiments of the present invention, and examples of the embodiments are shown in the drawings, where the same or similar designations throughout refer to the same or similar elements, or elements having the same or similar functions. The embodiments described below with reference to the drawings are illustrative and are used only for the purpose of explaining the present invention, and should not be understood as limiting the present invention.

[0020] Washing appliances such as dishwashers and washing machines are usually equipped with a water inlet valve, which controls the water source to flow into the washing appliance. If a power outage occurs in a user's home or the appliance is suddenly turned off, if the water inlet valve fails, the water source will continue to flow into the washing appliance, and the water in the washing appliance may overflow into the user's home. The continuous overflow may damage the electronic components of the washing appliance. Based on this, the present invention provides a water channel system for a washing appliance.

[0021] Combining Figure 1, according to the water channel system 100 of the cleaning device of an embodiment of the present invention, the water channel system 100 includes a flow path assembly 10, which includes a water inlet flow path 11 and a water outlet flow path 12 for supplying water to the cleaning device, specifically, the water outlet flow path 12 can supply water to the cleaning cavity of the cleaning device.

[0022] The waterway system 100 further includes a redirecting element 20, which is connected to the flow path assembly 10 and selectively controls the inlet flow path 11 to connect to the water source. Here, the redirecting element 20 selectively controls the inlet flow path 11 to connect to the water source, that is, the redirecting element 20 can control the water source to flow into the inlet flow path 11. When the inlet flow path 11 is connected to the water source, the water source can flow into the outlet flow path 12, and the outlet flow path 12 supplies water to the washing cavity of the washing device. When the passage between the inlet flow path 11 and the water source is closed, the water source cannot flow into the washing cavity of the washing device.

[0023] The waterway system 100 further includes an overflow pipe 30, which is connected to a redirecting element 20, and the redirecting element 20 is configured to control the overflow pipe 30 to connect to a water source when power is cut off. Here, the overflow pipe 30 can be connected to a sewer system in a user's home, and when the power of the cleaning device is cut off, the redirecting element 20 controls the overflow pipe 30 to connect to a water source, that is, after the power of the cleaning device is cut off, if there is a water source flowing into the cleaning device, the water can be directly discharged into the sewer system in the user's home through the overflow pipe 30. This protects the waterway system 100, and prevents the water source from continuously flowing into the cleaning device and overflowing into the user's home when the power of the device is cut off or the user's home suddenly experiences a power outage.

[0024] Note that the direction-changing element 20 controlling the launch channel 11 to connect to the water source means that the passage between the direction-changing element 20 and the launch channel 11 is open. The direction-changing element 20 being arranged to control the overflow pipe 30 to connect to the water source when the power is turned off means that the passage between the overflow pipe 30 and the water source is open when the power is turned off.

[0025] For example, the redirecting element 20 can be connected to a tap water source, and a water inlet valve 40 can be connected between the tap water source and the redirecting element 20, with the water inlet valve 40 controlling the opening and closing of the water source. When the cleaning device needs to inlet water, it opens the water inlet valve 40, and when it does not, it closes the water inlet valve 40 to stop the water supply. Furthermore, if a power outage occurs suddenly in a user's home, the power to the cleaning device is cut off and the water inlet valve 40 malfunctions, causing faucet water to continue flowing into the cleaning device. By providing the redirecting element 20, when the power is cut off, the overflow pipe 30 is connected to the water source, opening a passage between the overflow pipe 30 and the water source, allowing the water flow to be directly discharged from the overflow pipe 30. This allows the water source to continuously flow into the cleaning cavity of the cleaning device, thereby preventing flooding in the user's home.

[0026] In the cleaning device waterway system 100 of the embodiment of the present invention, the diverting element 20 is installed to selectively control the launching flow path 11 to connect to the water source, and when the cleaning device is powered off, the diverting element 20 is controlled to connect the overflow pipe 30 to the water source. If any water source flows into the cleaning device at this time, it can be discharged through the overflow pipe 30, preventing overflow caused by the water source continuously flowing into the cleaning cavity of the cleaning device. The diverting element 20 can protect the waterway system 100 in the event of a launching abnormality in the cleaning device, improving the safety of the cleaning device, and reducing the impact on the cleaning device by directly discharging water that abnormally flows into the launching flow path 11 through the overflow pipe 30.

[0027] Here, the diverting element 20 selectively controls the inlet flow path 11 to connect to the water source. For example, when the cleaning device is powered on, the diverting element 20 is controlled to connect the inlet flow path 11 to the water source. That is, when the cleaning device is powered on, the passage between the inlet flow path 11 and the water source is maintained in a connected state, allowing the water source to flow into the cleaning cavity of the cleaning device. When the cleaning device is powered off, the diverting element 20 can be controlled to close the passage between the inlet flow path 11 and the water source and connect the overflow pipe 30 to the water source. This prevents the water source from continuously flowing into the cleaning cavity of the cleaning device and discharges it into the sewer via the overflow pipe 30. Of course, when the cleaning device is powered on, the diverting element 20 can also selectively control the inlet flow path 11 to connect to the water source. For example, after a user selects a cleaning program via the control panel, the control panel can control the opening and closing of the passage between the inlet flow path 11 and the water source according to the selected cleaning program.

[0028] The overflow pipe 30 can be connected to the sewer system of the user's home, where the overflow pipe 30 can be an independent drainage line, or the cleaning device further includes a drainage flow path 15 used to drain the cleaning device, and the drainage flow path 15 can be connected to the overflow pipe 30 to reduce the number of pipes in the cleaning device.

[0029] In some embodiments of the present invention, the waterway system 100 further includes a drainage channel 15 used for draining the cleaning device. Specifically, the drainage channel 15 can be connected to the cleaning cavity, and when the cleaning device completes a cleaning program, the wastewater in the cleaning cavity is discharged into the sewer system of the user's house via the drainage channel 15. Here, the drainage channel 15 can be connected to an overflow pipe 30, thereby reducing the number of pipes in the cleaning device.

[0030] The drainage channel 15 may be provided with a one-way check valve 16 that can be unidirectionally conducted out of the washing cavity, thereby preventing the water in the drainage channel 15 from flowing into the washing cavity. When the water channel system 100 is under abnormal flooding, the water source can flow into the overflow pipe 30 and be directly discharged into the sewer system of the user's house, and the one-way check valve 16 can further prevent the water flow from flowing back into the washing cavity, thereby effectively protecting the water channel system 100.

[0031] 1 and 2 , in some embodiments of the present invention, the redirecting element 20 comprises a first interface 21, a second interface 22 and a third interface 23, the first interface 21 is used to connect a water source, the second interface 22 is connected to the launch channel 11, and the third interface 23 is connected to the overflow pipe 30. The redirecting element 20 includes an operating state and a power-off state, in the operating state, the first interface 21 and the second interface 22 are connected, and in the power-off state, the first interface 21 and the third interface 23 are connected.

[0032] Specifically, the first interface 21 may be the water inlet, and the second and third interfaces 22 and 23 may be the water outlets. By providing three interfaces on the diverting element 20, the water flow is branched into two outlet paths. When the cleaning device is operating normally, the diverting element 20 is in an operating state, and water can be supplied to the cleaning cavity of the cleaning device through the second interface 22. When the cleaning device is powered off, the diverting element 20 is in an off state, and the third interface 23 discharges water that has abnormally flowed into the cleaning device. Controlling the water flow through the diverting element 20 allows water to flow through different channels under different conditions, simplifying the control method of the waterway system 100.

[0033] In some embodiments of the present invention, the waterway system 100 further includes a water inlet valve 40, which may be connected to the first interface 21. The water inlet valve 40 can control the flow of water into the cleaning device. When the cleaning device begins a cleaning cycle, the water inlet valve 40 opens to allow water to flow into the cleaning device, and when the cleaning cycle ends, the water inlet valve 40 closes to stop injecting water into the cleaning device. Specifically, by providing the water inlet valve 40, the first interface 21 and the second interface 22 can remain connected when the diverting element 20 is in an operating state. That is, at this time, the cleaning device controls the water source to flow into the first interface 21 through the water inlet valve 40, simplifying the control method of the waterway system 100 and improving the reliability of the waterway system 100.

[0034] Here, the diverting element 20 is disposed between the launch valve 40 and the flow path assembly 10, the launch valve 40 is connected to the first interface 21 of the diverting element 20, and the diverting element 20 is connected to the overflow pipe 30. When the power of the cleaning device is cut off and the launch valve 40 fails, the water abnormally flowing into the cleaning device can be directly discharged through the overflow pipe 30, thereby reducing the impact on the flow path assembly 10.

[0035] In some embodiments of the present invention, the redirecting element 20 may be a three-way solenoid valve, and the valve switching can be controlled by power on and power off to realize the control of the water flow, simplify the control method of the waterway system 100, and improve the reliability of the waterway system 100.

[0036] In some embodiments of the present invention, the redirecting element 20 has opposing first and second sides, the first interface 21 being located on the first side, and the second interface 22 and the third interface 23 being located on the second side, thereby making full use of the space in the cleaning device and making the structure of the waterway system 100 compact.

[0037] Combining FIG. 1, the waterway system 100 further includes an air cavity 13, which is connected to the outer space of the waterway system 100 and can balance pressure during cleaning or draining of the cleaning device.

[0038] Here, the redirecting element 20 is arranged between the launch valve 40 and the air cavity 13, that is, the redirecting element 20 is arranged outside the air cavity 13, reducing the impact on the air cavity 13 and facilitating maintenance on the redirecting element 20.

[0039] For example, the redirecting element 20 is disposed between the air cavity 13 and the launching valve 40, and the launching passage 11 and the overflow pipe 30 are both disposed outside the air cavity 13. When the cleaning device is operating normally, the water source can be connected to the launching passage 11. At this time, the water flows into the air cavity 13 via the launching passage 11. When the cleaning device is powered off, the water source and the overflow pipe 30 are connected. At this time, if the launching valve 40 fails, the water abnormally flowing into the cleaning device can be directly discharged from the overflow pipe 30, without having to go through the air cavity 13, thereby reducing the impact on the air cavity 13.

[0040] 1 , in some embodiments of the present invention, the overflow pipe 30 is provided outside the flow path assembly 10. When the power of the cleaning device is turned off, the redirecting element 20 is controlled to connect the overflow pipe 30 to the water source. At this time, if the water inlet valve 40 fails, the water abnormally flowing into the cleaning device can be directly discharged from the overflow pipe 30 without passing through the flow path assembly 10, thereby reducing the impact on the flow path assembly 10.

[0041] 1, in some embodiments of the present invention, the waterway system 100 further includes a drainage channel 15 for draining the cleaning device, and the drainage channel 15 can be connected to the cleaning cavity. When the cleaning completes the cleaning program, the wastewater in the cleaning cavity is discharged to the sewer of the user's house via the drainage channel 15.

[0042] Here, the inlet water flow path 11 and the outlet water flow path 12 can be connected to the air cavity 13 to prevent backflow during inlet water. Alternatively, the drain water flow path 15 can be connected to the air cavity 13 to prevent backflow during drainage. Of course, the inlet water flow path 11, the outlet water flow path 12 and the drain water flow path 15 can all be connected to the air cavity 13 to balance the pressure during cleaning or drainage of the cleaning device and improve the reliability of the cleaning device.

[0043] Furthermore, the surface of the channel assembly 10 is provided with a content interface 131 communicating with the air cavity 13. For example, when the washing machine is operating, water is supplied into the washing cavity through the water outlet channel 12, and the water supplied into the washing cavity can be preheated to improve the washing effect. The water forms a certain amount of steam when it flows into the washing cavity, and the washing machine needs to discharge the water from the washing cavity after completing the washing of the dishes. The channel assembly 10 maintains the air pressure balance in the washing cavity, improving the working stability of the dishwasher.

[0044] In some embodiments of the present invention, an air vent 132 is provided on the surface of the channel assembly 10, and the air vent 132 is connected to the air cavity 13. The channel assembly 10 is connected to the outside world through the air vent 132, and can maintain the air pressure balance in the air cavity 13 and prevent the backflow of water.

[0045] 1 , in some embodiments of the present invention, the drainage flow path 15 includes a first branch 151 and a second branch 152, the first branch 151 and the second branch 152 are connected to each other, the first branch 151 is connected to the cleaning cavity of the cleaning device, and the second branch 152 is connected to the overflow pipe 30. When the cleaning completes the cleaning program, the wastewater in the cleaning cavity flows into the first branch 151 and then into the second branch 152, and is discharged into the sewer of the user's house through the overflow pipe 30. The second branch 152 is connected to the overflow pipe 30, which can reduce the number of pipes in the cleaning device and further simplify the drainage pipes of the cleaning device.

[0046] In some embodiments of the present invention, a one-way check valve 16 is provided in the first branch passage 151, which is unidirectionally connected to the outside of the cleaning cavity. In other words, the one-way check valve 16 restricts the wastewater in the cleaning cavity to be discharged only from the cleaning cavity to the drain passage 15, and prevents the water in the drain passage 15 from flowing into the inside of the cleaning cavity, thereby improving the reliability of the cleaning device.

[0047] In some embodiments of the present invention, the second branch 152 is connected to the air cavity 13 to avoid backflow phenomenon during drainage.

[0048] In some embodiments of the present invention, the channel assembly 10 is configured as a plate with a built-in channel, which allows the channel assembly 10 to have a compact structure and be easily integrated into the side wall of the cleaning device, thereby saving the internal space of the cleaning device. For example, the channel assembly 10 may include an inner cavity inlet channel, a recycle cavity inlet channel, a drain channel, and the like.

[0049] In some embodiments of the present invention, the channel assembly 10 is a breathing apparatus, which is a component that balances the cleaning cavity of the cleaning apparatus with the ambient air pressure. By installing the channel assembly 10 as a breathing apparatus and providing the inlet channel 11 and the outlet channel 12 in the breathing apparatus, the inlet channel 11 and the outlet channel 12 can be connected to the outside, preventing the water in the channels from flowing back and improving the operating stability of the cleaning apparatus.

[0050] The following describes the waterway system 100 of some embodiments of the present invention in combination with FIGS.

[0051] The waterway system 100 can be arranged to be connected to a tap water source, and includes a flow path assembly 10, a redirecting element 20, and an overflow pipe 30. A water inlet valve 40 can be connected between the flow path assembly 10 and the tap water source. The redirecting element 20 can be provided between the launch valve 40 and the flow path assembly 10. The flow path assembly 10 includes an inlet flow path 11 and an outlet flow path 12 for supplying water to the cleaning device. The flow path assembly 10 can include a drainage flow path 15 for draining water from the cleaning device. The drainage flow path 15 can include a first branch 151 and a second branch 152. The first branch 151 can be connected to the cleaning cavity and arranged to drain wastewater from the internal cavity of the cleaning device, and the second branch 152 can be connected to a sewer system in a user's home.

[0052] 3, which shows the water flow when the waterway system 100 is normally launched. When the cleaning device is working normally, the redirecting element 20 can be in an operating state, the first interface 21 and the second interface 22 are in communication, connecting the launch channel 11 to the water source, and water flows from the launch channel 11 through the air cavity 13 to the outflow channel 12 and into the cleaning cavity.

[0053] 4, the washing and draining path of the washing machine is shown. After the washing machine completes the washing operation, the drain pump of the washing machine is activated, and the wastewater in the inner cavity of the washing machine flows into the first branch 151, flows into the air cavity 13, and is drained into the sewer of the user's house via the second branch 152.

[0054] Here, a one-way check valve 16 can be connected to the first branch 151, and is arranged to allow the water in the washing cavity to flow in one direction, thereby preventing the water in the drainage channel 15 from flowing into the washing cavity. That is, when the waterway system 100 is under abnormal flooding, the water flow can flow into the overflow pipe 30 and be directly discharged into the sewer system of the user's home, preventing the water flow from flowing into the washing cavity and effectively protecting the waterway system 100.

[0055] 5, which shows the water flow when the waterway system 100 is abnormally launched. Illustratively, when the power of the cleaning device is turned off, the redirecting element 20 is in a power-off state, the redirecting element 20 closes the passage between the water source and the launching flow path 11, connects the first interface 21 and the third interface 23, and connects the water source with the overflow pipe 30, so that the water directly flows into the overflow pipe 30 and is discharged into the sewer of the user's house.

[0056] Optionally, the water outlet flow path 12 includes an inner cavity launch pipe 121 and a recycle cavity launch pipe 122 and is arranged to allow water to pass through the inner cavity launch pipe 121 and the recycle cavity launch pipe 122 to the wash cavity.

[0057] For example, the waterway system 100 may further include a water softener, and the flow path assembly 10 may be connected to the water softener via a recycle cavity water inlet pipe 122. Specifically, when the washing machine is in an operating state, the redirecting element 20 is controlled to connect the water inlet flow path 11 to a water source, and the water flow may flow into the water inlet flow path 11, with a portion of the water flowing into the washing cavity via the inner cavity water inlet pipe 121. A portion of the water flowing into the water softener via the recycle cavity water inlet pipe 122 may be softened by the water softener before flowing into the washing inner cavity, facilitating the removal of hardness components such as calcium and magnesium ions in tap water, thereby preventing the formation of scale during washing and improving the service life of the washing machine.

[0058] According to the embodiment of the present invention, the cleaning device includes the above-mentioned waterway system 100. The cleaning device of this embodiment adopts the technical solution of the above-mentioned embodiment, and therefore has at least the beneficial effects of the technical solution of the above-mentioned embodiment, which will be omitted here.

[0059] Illustratively, the cleaning appliance may be a dishwasher.
