Detailed implementation manners

[0025] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation of the present utility model.

[0026] Washing equipment such as dishwashers and washing machines are usually provided with a water inlet valve to control the water source to enter the interior of the washing equipment through the water inlet valve. When there is a power outage at the user's home or the equipment suddenly loses power, if the water inlet valve fails, the water source will continuously enter the washing equipment, causing the water in the washing equipment to overflow into the user's home, and the continuous overflow may damage the electronic components of the washing equipment. Based on this, the present utility model provides a water circuit system for a washing equipment.

[0027] Combined with Figure 1 , according to the water circuit system 100 of the washing equipment according to an embodiment of the present utility model, the water circuit system 100 includes a flow path assembly 10. The flow path assembly 10 includes a water inlet flow path 11 and a water outlet flow path 12 for supplying water to the washing equipment. Specifically, the water outlet flow path 12 can supply water to the washing cavity of the washing equipment.

[0028] The water circuit system 100 further includes a reversing element 20. The reversing element 20 is connected to the flow path assembly 10, and the reversing element 20 selectively controls the water inlet flow path 11 to be connected to the water source. Among them, the reversing element 20 selectively controls the water inlet flow path 11 to be connected to the water source. In other words, the reversing element 20 can control the water source to enter the water inlet flow path 11. When the water inlet flow path 11 is connected to the water source, the water source can enter the water outlet flow path 12 and supply water to the washing cavity of the washing equipment from the water outlet flow path 12. When the channel between the water inlet flow path 11 and the water source is closed, the water source will not enter the washing cavity.

[0029] The waterway system 100 further includes an overflow pipe 30. The overflow pipe 30 is connected to a commutation element 20, and the commutation element 20 is configured to control the overflow pipe 30 to connect to a water source when powered off. Among them, the overflow pipe 30 can be connected to the sewer in the user's home. When the washing device is powered off, the commutation element 20 controls the overflow pipe 30 to connect to the water source. That is to say, after the washing device is powered off, if there is water entering the washing device, the water can be directly discharged into the sewer in the user's home through the overflow pipe 30 to protect the waterway system 100 and prevent water from continuously entering the washing device when the device is powered off or there is a sudden power outage in the user's home, resulting in water overflowing into the user's home.

[0030] It should be noted that the commutation element 20 controlling the water inlet channel 11 to connect to the water source means that the channel between the commutation element 20 and the water inlet channel 11 is open. The commutation element 20 being configured to control the overflow pipe 30 to connect to the water source when powered off means that the channel between the overflow pipe 30 and the water source is open when powered off.

[0031] Exemplarily, the commutation element 20 can be connected to a tap water source, and an inlet valve 40 can be further connected between the tap water source and the commutation element 20. The inlet valve 40 can control the opening or closing of the water source. When the washing device needs to take in water, the inlet valve 40 is opened, and when water intake is not required, the inlet valve 40 is closed to stop the water supply. It can be understood that when there is a sudden power outage in the user's home and the washing device is powered off, if the inlet valve 40 fails, the water from the faucet will continuously enter the washing device. By setting the commutation element 20, when powered off, the overflow pipe 30 is connected to the water source, and the channel between the overflow pipe 30 and the water source is opened, and the water flow can be directly discharged from the overflow pipe 30, preventing the water source from continuously entering the washing cavity of the washing device and causing water overflow in the user's home.

[0032] According to the waterway system 100 of the washing device according to the embodiment of the present invention, by setting the commutation element 20, the water inlet channel 11 can be selectively controlled to connect to the water source. When the washing device is powered off, the commutation element 20 controls the overflow pipe 30 to connect to the water source. At this time, if there is water entering the washing device, it can be discharged through the overflow pipe 30, preventing the water source from continuously entering the washing cavity of the washing device and causing water overflow. The commutation element 20 can protect the waterway system 100 when the water intake of the washing device is abnormal, improve the use safety of the washing device, and the water abnormally entering the water inlet channel 11 can be directly discharged from the overflow pipe 30, which can reduce the impact on the washing device.

[0033] Among them, the commutation element 20 selectively controls the water inlet channel 11 to connect to the water source. Exemplarily, when the washing device is powered on, the commutation element 20 can control the water inlet channel 11 to connect to the water source. In other words, when the washing device is powered on, the channel between the water inlet channel 11 and the water source can always be in a connected state, so that the water source can enter the washing cavity of the washing device. When the washing device is powered off, the commutation element 20 can close the channel between the water inlet channel 11 and the water source and control the overflow pipe 30 to connect to the water source, so as to prevent the water source from continuously entering the washing cavity of the washing device and discharging it to the sewer through the overflow pipe 30. Of course, when the washing device is powered on, the commutation element 20 can also selectively control the water inlet channel 11 to connect to the water source. For example, after the user selects a washing program through the control panel, the control board can control the opening and closing of the channel between the water inlet channel 11 and the water source according to the selected washing program.

[0034] The overflow pipe 30 can be connected to the sewer in the user's home. Among them, the overflow pipe 30 can be a separate drainage pipeline; or, the washing device further includes a drainage channel 15 for draining the washing device, and the drainage channel 15 can be connected to the overflow pipe 30 to reduce the number of pipelines of the washing device.

[0035] In some embodiments of the present utility model, the water circuit system 100 further includes a drainage channel 15 for draining the washing device. Specifically, the drainage channel 15 can be connected to the washing cavity. When the washing program is completed, the sewage in the washing cavity is discharged to the sewer in the user's home through the drainage channel 15. Among them, the drainage channel 15 can be connected to the overflow pipe 30, which can reduce the number of pipelines of the washing device.

[0036] The drainage channel 15 can be provided with a one-way check valve 16 that can conduct unidirectionally towards the outside of the washing cavity, which can prevent the water flow in the drainage channel 15 from flowing into the washing cavity. When the water circuit system 100 abnormally intakes water, the water source enters the overflow pipe 30 and can be directly discharged to the sewer in the user's home. The one-way check valve 16 can also prevent the water flow from reversely entering the washing cavity, so as to effectively protect the water circuit system 100.

[0037] Combined with Figure 1 and Figure 2 , in some embodiments of the present utility model, the commutation element 20 has a first interface 21, a second interface 22 and a third interface 23. The first interface 21 is used to connect to the water source, the second interface 22 communicates with the water inlet channel 11, and the third interface 23 communicates with the overflow pipe 30. The commutation element 20 includes a working state and a power-off state. In the working 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.

[0038] Specifically, the first interface 21 can be the inlet of the water flow, and the second interface 22 and the third interface 23 can be the outlets of the water flow. By providing three interfaces on the reversing element 20, it is convenient to divide the water flow into two outflow paths. When the washing device is operating normally, the reversing element 20 is in the working state, and water can be supplied to the washing chamber of the washing device through the second interface 22. When the washing device is powered off, the reversing element 20 is in the powered-off state, and the water that abnormally enters the washing device can be discharged through the third interface 23. The flow direction of the water flow is controlled by the reversing element 20 to enable the water flow to flow into different flow paths in different states, simplifying the control method of the water circuit system 100.

[0039] In some embodiments of the present invention, the water circuit system 100 further includes a water inlet valve 40. The water inlet valve 40 can be connected to the first interface 21. The water inlet valve 40 can control the water flow into the washing device, open when the washing device starts a washing cycle to allow the water flow to enter the washing device, and close after the washing is completed to stop the water supply to the washing device. Specifically, by providing the water inlet valve 40, when the reversing element 20 is in the working state, the first interface 21 and the second interface 22 can always be connected. That is to say, at this time, the washing device controls the water source to enter the first interface 21 through the water inlet valve 40, simplifying the control method of the water circuit system 100 and improving the reliability of the water circuit system 100.

[0040] Among them, the reversing element 20 is provided between the water inlet valve 40 and the flow path assembly 10. The water inlet valve 40 is connected to the first interface 21 of the reversing element 20, and the reversing element 20 is connected to the overflow pipe 30. When the washing device is powered off, if the water inlet valve 40 fails, the water that abnormally enters the washing device can be directly discharged from the overflow pipe 30, which can reduce the impact on the flow path assembly 10.

[0041] In some embodiments of the present invention, the reversing element 20 can be a three-way solenoid valve, which controls the switching of the valve through energization and de-energization, and thus realizes the control of the flow direction of the water flow, simplifies the control method of the water circuit system 100, and improves the reliability of the water circuit system 100.

[0042] In some embodiments of the present invention, the reversing element 20 has opposite first and second sides. The first interface 21 is located on the first side, and the second interface 22 and the third interface 23 are located on the second side, so as to make full use of the space of the washing device and make the structure of the water circuit system 100 compact.

[0043] Combined Figure 1 with this, the water circuit system 100 may further include an air chamber 13. The air chamber 13 communicates with the outer space of the water circuit system 100 and can balance the pressure in the washing device during the washing or draining process.

[0044] Among them, the commutation element 20 is arranged between the water inlet valve 40 and the air chamber 13. In other words, the commutation element 20 is arranged outside the air chamber 13, which can reduce the influence on the air chamber 13 and is convenient for maintaining the commutation element 20.

[0045] Exemplarily, the commutation element 20 can be arranged between the air chamber 13 and the water inlet valve 40. Both the water inlet flow channel 11 and the overflow pipe 30 are arranged outside the air chamber 13. When the washing device is working normally, the water source and the water inlet flow channel 11 can be connected. At this time, the water flow can enter the air chamber 13 through the water inlet flow channel 11; when the washing device is powered off, the water source and the overflow pipe 30 are connected. At this time, if the water inlet valve 40 fails, the water abnormally entering the washing device can be directly discharged from the overflow pipe 30 without passing through the air chamber 13, which can reduce the influence on the air chamber 13.

[0046] Combined with Figure 1 , in some embodiments of the present utility model, the overflow pipe 30 can be arranged outside the flow path assembly 10. When the washing device is powered off, the commutation element 20 controls the overflow pipe 30 to be connected to the water source. At this time, if the water inlet valve 40 fails, the water abnormally entering the washing device can be directly discharged from the overflow pipe 30 without passing through the flow path assembly 10, which can reduce the influence on the flow path assembly 10.

[0047] Combined with Figure 1 , in some embodiments of the present utility model, the water circuit system 100 further includes a drainage flow channel 15 for draining water from the washing device. The drainage flow channel 15 can be connected to the washing chamber. When the washing program is completed, the sewage in the washing chamber is discharged through the drainage flow channel 15 to the sewer in the user's home.

[0048] Among them, the water inlet flow channel 11 and the water outlet flow channel 12 can be connected to the air chamber 13, which can avoid the backflow phenomenon during the water inlet process; or, the drainage flow channel 15 is connected to the air chamber 13, which can avoid the backflow phenomenon during the drainage process. Of course, it can also be that the water inlet flow channel 11, the water outlet flow channel 12 and the drainage flow channel 15 are all connected to the air chamber 13, which can balance the pressure of the washing device during the washing or drainage process and improve the reliability of the washing device.

[0049] Furthermore, the surface of the flow path assembly 10 is provided with an inner tank interface 131 communicating with the air chamber 13. Exemplarily, when the washing device is working, water flow is introduced into the washing chamber through the water outlet flow channel 12. In order to improve the cleaning effect, the water flow introduced into the washing chamber can be preheated. When the water flow enters the washing chamber, a certain amount of steam will be formed. After the washing device finishes washing the tableware, the water in the washing chamber needs to be drained away. The air pressure balance of the washing chamber can be maintained through the flow path assembly 10, and the working stability of the dishwasher can be improved.

[0050] In some embodiments of the present utility model, an air port 132 is provided on the surface of the flow path assembly 10, and the air port 132 communicates with the air cavity 13. The flow path assembly 10 can communicate with the outside through the air port 132, thereby maintaining the air pressure balance in the air cavity 13 and avoiding the phenomenon of reverse water flow.

[0051] Combined with Figure 1 , in some embodiments of the present utility model, the drainage channel 15 includes a first branch 151 and a second branch 152. The first branch 151 and the second branch 152 are connected. The first branch 151 is connected to the washing cavity of the washing device, and the second branch 152 is connected to the overflow pipe 30. When the washing device completes the washing program, the sewage in the washing cavity first enters the first branch 151 and then enters the second branch 152, and is discharged from the overflow pipe 30 to the sewer in the user's home. The connection of the second branch 152 to the overflow pipe 30 can reduce the number of pipelines of the washing device, thereby simplifying the drainage pipeline of the washing device.

[0052] In some embodiments of the present utility model, a one-way check valve 16 that conducts unidirectionally toward the outside of the washing cavity is provided in the first branch 151. That is to say, the one-way check valve 16 restricts the sewage in the washing cavity to only be discharged from the washing cavity to the drainage channel 15, and the water in the drainage channel 15 cannot enter the inside of the washing cavity, improving the reliability of the washing device.

[0053] In some embodiments of the present utility model, the second branch 152 communicates with the air cavity 13, which can avoid the phenomenon of reverse flow during the drainage process.

[0054] In some embodiments of the present utility model, the flow path assembly 10 is configured as a plate shape with internal flow channels. The structure of the flow path assembly 10 is compact, and it is convenient to integrate the flow path assembly 10 on the side wall of the washing device, saving the internal space of the washing device. Exemplarily, the internal cavity of the flow path assembly 10 can integrate an internal cavity water inlet flow, a regeneration cavity water inlet channel, a drainage channel, etc.

[0055] In some embodiments of the present utility model, the flow path assembly 10 is a breather. It should be noted that a breather is a component that balances the air pressure between the washing cavity of the washing device and the outside. By setting the flow path assembly 10 as a breather and providing a water inlet channel 11 and a water outlet channel 12 on the breather, the water inlet channel 11 and the water outlet channel 12 can communicate with the outside, avoiding the reverse flow of water in the flow channel and improving the working stability of the washing device.

[0056] The following combines Figures 3 to 5 to illustrate the water circuit system 100 of some specific embodiments of the present utility model.

[0057] The waterway system 100 can be configured to connect to a tap water source. The waterway system 100 includes a flow path assembly 10, a commutation element 20, and an overflow pipe 30. An inlet valve 40 can also be connected between the flow path assembly 10 and the tap water source. The commutation element 20 can be disposed between the inlet 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 a washing device. The flow path assembly 10 may further include a drainage flow path 15 for draining the washing device. The drainage flow path 15 may include a first branch 151 and a second branch 152. The first branch 151 can be connected to the washing chamber and is configured to discharge the sewage in the inner cavity of the washing device. The second branch 152 can be connected to the sewer in the user's home.

[0058] Combined with Figure 3 , in which, the water flow direction when the waterway system 100 is normally inletting water is shown. When the washing device is working normally, the commutation element 20 can be in a working state, the first interface 21 and the second interface 22 are connected, so that the inlet flow path 11 is connected to the water source, and water flows from the inlet flow path 11 through the air chamber 13 to the outlet flow path 12 and enters the washing chamber.

[0059] Combined with Figure 4 , in which, the drainage path of the washing device during washing is shown. After the washing device finishes the washing work, the drainage pump of the washing device works, the sewage in the inner cavity of the washing device enters the first branch 151, and enters the air chamber 13, and flows through the second branch 152 and is discharged into the sewer in the user's home.

[0060] Wherein, the first branch 151 can be connected with a one-way check valve 16 and is configured to conduct the water in the washing chamber unidirectionally, which can prevent the water in the drainage flow path 15 from flowing back into the washing chamber. That is to say, when the waterway system 100 abnormally intakes water, the water flows into the overflow pipe 30 and can be directly discharged into the sewer in the user's home, avoiding the water from entering the washing chamber, so as to effectively protect the waterway system 100.

[0061] Combined with Figure 5 , in which, the water flow direction when the waterway system 100 abnormally intakes water is shown. Exemplarily, when the washing device is powered off, the commutation element 20 is in a powered-off state, the commutation element 20 closes the channel between the water source and the inlet flow path 11, the first interface 21 and the third interface 23 are connected, so that the water source is connected to the overflow pipe 30, and water flows directly to the overflow pipe 30 and is discharged into the sewer in the user's home.

[0062] Optionally, the outlet flow path 12 may include an inner cavity water inlet pipe 121 and a regeneration cavity water inlet pipe 122, and is configured to supply water to the washing chamber through the inner cavity water inlet pipe 121 and the regeneration cavity water inlet pipe 122.

[0063] Exemplarily, the waterway system 100 may further include a water softener, and the flow path assembly 10 may be connected to the water softener through the regeneration chamber inlet pipe 122. Specifically, when the washing device is in the working state, the commutation element 20 controls the water inlet flow path 11 to connect to the water source, and water flows into the water inlet flow path 11. A part of the water flow can enter the washing chamber through the inner cavity inlet pipe 121, and a part of the water flow can enter the water softener through the regeneration chamber inlet pipe 122, and then enter the washing inner cavity after being softened by the water softener, which is convenient for removing hardness components such as calcium and magnesium ions in tap water, thereby avoiding the generation of scale during the washing process and improving the service life of the washing device.

[0064] The washing device according to an embodiment of the present invention includes the aforementioned waterway system 100. The washing device of this embodiment adopts the technical solution of the above embodiment, and thus at least has the beneficial effects brought by the technical solution of the above embodiment, which will not be repeated here.
