DETAILED DESCRIPTION

[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0029] Washing equipment such as dishwashers and washing machines are usually equipped with water inlet valves, which control the water source to enter the washing equipment. When the user's home is out of power or the equipment is suddenly out of power, if the water inlet valve fails, the water source will continue to enter the washing equipment, causing the water in the washing equipment to overflow into the user's home, and the continuous overflow may cause damage to the electronic components of the washing equipment. Based on this, the utility model proposes a water system for washing equipment.

[0030] Combination Figure 1 and Figure 2 The water system includes an inlet channel 10 for connecting to a water source, an outlet channel 20 for supplying water to a washing device, and a drain channel 30 for draining water from the washing device. The water system also includes a reversing element 40, which selectively controls the inlet channel 10 to connect to the outlet channel 20, and the reversing element 40 is configured to connect the inlet channel 10 and the drain channel 30 when power is off.

[0031] Specifically, the water inlet channel 10 can be configured to be connected to a tap water source and supply water to the washing chamber of the washing device through the water outlet channel 20. The drainage channel 30 can be connected to the sewer in the user's home. The reversing element 40 selectively controls the water inlet channel 10 to connect to the water outlet channel 20. In other words, the reversing element 40 can control the water inlet channel 10 to be connected or closed to the water outlet channel 20. When the water inlet channel 10 is connected to the water outlet channel 20, the water source can enter the washing chamber of the washing device through the water outlet channel 20. When the water inlet channel 10 is closed to the water outlet channel 20, the water source will not enter the washing chamber of the washing device. When the washing device is powered off, the reversing element 40 connects the water inlet channel 10 and the drainage channel 30. That is to say, after the washing device is powered off, if water enters the water inlet channel 10, the water can be discharged to the sewer in the user's home through the drainage channel 30 to protect the water system and prevent water from continuing to enter the washing device when the device is powered off or there is a sudden power outage in the user's home, causing water to overflow into the user's home.

[0032] Exemplarily, the water inlet channel 10 can be connected to a faucet, and a water inlet valve 211 can be connected between the water inlet channel 10 and the faucet. The water inlet valve 211 can control the opening or closing of the water source. When the washing device needs to take in water, the water inlet valve 211 is opened, and when water is not needed, the water inlet valve 211 is closed to stop the water supply. It can be understood that when there is a sudden power outage in the user's home, the washing device is powered off. If the water inlet valve 211 fails, the water from the faucet will continue to enter the water inlet channel 10. By setting a reversing element 40, the water inlet channel 10 and the drainage channel 30 are connected when the power is off, and the water flow can be discharged directly from the drainage channel 30, thereby preventing the water source from continuously entering the washing chamber of the washing device, causing overflow in the user's home.

[0033] According to the water system of the washing device in the embodiment of the utility model, the water inlet channel 10 and the water outlet channel 20 can be selectively connected by setting a reversing element 40. When the washing device is powered off, the reversing element 40 connects the water inlet channel 10 and the water outlet channel 30. At this time, if water enters the water inlet channel 10, it can be discharged through the water outlet channel 30, so as to avoid water continuously entering the washing chamber of the washing device and causing overflow. The reversing element 40 can protect the water system when the water inlet of the washing device is abnormal, thereby improving the safety of the washing device.

[0034] Among them, the reversing element 40 selectively controls the water inlet flow channel 10 to connect with the water outlet flow channel 20. For example, when the washing device is powered on, the reversing element 40 can control the water inlet flow channel 10 to connect with the water outlet flow channel 20. In other words, when the washing device is powered on, the water inlet flow channel 10 and the water outlet flow channel 20 can be always in a connected state, so that the water source enters the washing chamber of the washing device. When the washing device is powered off, the reversing element 40 closes the water inlet flow channel 10 and the water outlet flow channel 20, and connects the water inlet flow channel 10 and the drainage flow channel 30 to prevent the water source from continuously entering the washing device, and drains the water through the drainage flow channel 30. Of course, when the washing device is powered on, the reversing element 40 can also selectively control the water inlet flow channel 10 to connect with the water outlet flow channel 20. For example, after the user selects a washing program through the control panel, the control panel can control the opening and closing of the water inlet flow channel 10 and the water outlet flow channel 20 according to the selected washing program.

[0035] Combination Figure 2 and Figure 4 , wherein the reversing element 40 can be installed at different positions of the washing equipment. For example, the washing equipment is a dishwasher, which may include a breather. The reversing element 40 can be installed inside the breather, which can save space in the dishwasher and improve the space utilization rate of the dishwasher. Of course, the reversing element 40 can be installed outside the breather to facilitate the design and processing of the pipe and water system and facilitate the later maintenance of the dishwasher.

[0036] Combination Figure 2 and Figure 3 In some embodiments of the utility model, the reversing element 40 may have a first interface 41, a second interface 42 and a third interface 43. The first interface 41 is connected to the water inlet channel 10, the second interface 42 is connected to the water outlet channel 20, and the third interface 43 is connected to the drainage channel 30. The reversing element 40 includes a working state and a power-off state. In the working state, the first interface 41 and the second interface 42 are connected, and in the power-off state, the first interface 41 and the third interface 43 are connected.

[0037] Specifically, the first interface 41 can be the inlet of the water flow, and the second interface 42 and the third interface 43 can be the outlet of the water flow. By setting three interfaces on the reversing element 40, the water flow can be divided into two outflow paths. When the washing device is working normally, the reversing element 40 is in a working state, and water can be supplied to the washing chamber of the washing device through the second interface 42. When the washing device is powered off, the reversing element 40 is in a power-off state, and water that abnormally enters the water inlet channel 10 can be discharged through the third interface 43. The flow direction of the water flow is controlled by the reversing element 40, so that the water flows to different flow paths under different conditions, simplifying the control method of the water system.

[0038] Exemplarily, the reversing element 40 may be an electromagnetic reversing valve, which controls the switching of the valve by powering on and off, thereby controlling the flow direction of the water flow, simplifying the control method of the water system, and improving the reliability of the water system.

[0039] In some embodiments of the present invention, the water inlet channel 10, the water outlet channel 20 and the drainage channel 30 are all provided in the water channel assembly 100 to simplify the flow channel design of the water channel system and optimize the overall structure of the water channel system. Figure 3 The water system may include an internal drainage pipe 230 connected to the washing chamber of the washing device. The drainage channel 30 may be connected to the washing chamber through the internal drainage pipe 230. When the washing process is completed, the sewage in the washing chamber may enter the drainage channel 30 through the internal drainage pipe 230 and be discharged to the sewer pipe in the user's home. A one-way valve 231 is connected between the drainage channel 30 and the washing chamber to prevent the water in the drainage channel 30 from flowing back to the washing chamber. When the washing device is powered off, the water that abnormally enters the water inlet channel 10 is also discharged through the drainage channel 30. Because a one-way valve 231 is provided between the drainage channel 30 and the washing chamber, the water in the drainage channel 30 will not enter the washing chamber.

[0040] In some embodiments of the present invention, the water channel assembly 100 is constructed in a plate shape, so that the structure of the water channel system is compact, and the water channel assembly 100 is conveniently integrated on the side wall of the washing device, saving the internal space of the washing device. In addition, the water inlet flow channel 10, the water outlet flow channel 20 and the drainage flow channel 30 are integrated into the water channel assembly, making full use of the space of the water channel assembly 100, making the structure of the washing device compact.

[0041] In some embodiments of the present invention, the reversing element 40 is disposed in the water channel assembly 100. Integrating the reversing element 40 in the water channel assembly 100 can fully utilize the space in the water channel assembly 100 and improve the space utilization rate of the water channel assembly 100.

[0042] In some embodiments of the present invention, the water inlet channel 10, the water outlet channel 20 and the drainage channel 30 are arranged in the water channel assembly 100, and the reversing element 40 is arranged in the water channel assembly 100, which facilitates the modular design of the water channel system, improves the versatility of the water channel system, and improves the assembly efficiency of the washing equipment.

[0043] Combination Figure 2 and Figure 5 Furthermore, the water channel assembly 100 may be provided with a mounting groove 50, the outlet of the water inlet channel 10, the inlet of the water outlet channel 20 and the inlet of the drainage channel 30 are arranged on the inner side of the mounting groove 50, and at least a portion of the reversing element 40 is arranged in the mounting groove 50. In other words, the entire reversing element 40 may be arranged in the mounting groove 50, or a portion of the reversing element 40 is arranged in the mounting groove 50. The mounting groove 50 can position and install the reversing element 40 to improve the structural stability of the reversing element 40.

[0044] The water channel assembly 100 is provided with a mounting groove 50 , and the reversing element 40 is disposed in the mounting groove 50 . The reversing element 40 is positioned and installed by the water channel assembly 100 , so as to fully utilize the space in the water channel assembly 100 and improve the structural stability of the reversing element 40 .

[0045] Exemplarily, the reversing element 40 may include a valve body and an interface, wherein the interface is used to connect the water inlet channel 10, the water outlet channel 30 and the water outlet channel 20, and the interface of the reversing element 40 may be arranged in the mounting groove 50, and the mounting groove 50 can position and install the reversing element 40 to improve the structural stability and installation efficiency of the reversing element 40. The valve body is arranged outside the mounting groove 50, and the water channel assembly 100 may be provided with a avoidance groove for avoiding the valve body to facilitate heat dissipation of the valve body.

[0046] In some embodiments of the present invention, the mounting groove 50 has a first side surface and a second side surface relative to each other, the outlet of the water inlet channel 10 is arranged on the first side surface, and the inlet of the water outlet channel 20 and the inlet of the drainage channel 30 are arranged on the second side surface, so as to optimize the flow channel of the water channel assembly 100 to fully utilize the space in the water channel system and make the structure of the water channel system compact.

[0047] Exemplarily, the reversing element 40 may have a working state and a power-off state. In the working state, the reversing element 40 connects the water inlet channel 10 and the water outlet channel 20, and the water flows from the water inlet channel 10 into the reversing element 40 and enters the inlet of the water outlet channel 20. In the power-off state, the reversing element 40 connects the water inlet channel 10 and the water outlet channel 30. At this time, if water flows into the water inlet channel 10, it can enter the inlet of the water outlet channel 30 through the reversing element 40. Among them, the inlet of the water outlet channel 20 and the inlet of the water outlet channel 30 are arranged on the same side, which is convenient for the design of the flow channel in the water channel assembly 100, and the structure of the water channel assembly 100 is compact by optimizing the flow direction of water.

[0048] Combination Figure 7 In some embodiments of the present invention, the water inlet channel 10 and the drainage channel 30 are arranged along the left and right directions of the water channel assembly 100 and are disposed below the water channel assembly 100. When the washing machine is powered off, the reversing element 40 connects the water inlet channel 10 and the drainage channel 30. At this time, if water flows into the water inlet channel 10, it can be directly discharged from the drainage channel 30, thereby optimizing the flow channel of the water channel assembly 100, making the overall structure of the water channel assembly 100 compact, and improving the drainage efficiency of the washing machine when water is abnormally inflowing.

[0049] Combination Figure 6 In some embodiments of the present invention, the outlet flow channel 20 includes a first flow channel 21 and a second flow channel 22 connected to each other. The first flow channel 21 is arranged above the inlet flow channel 10, and the second flow channel 22 extends along the up-down direction of the water channel assembly 100 and is located on the right side of the inlet flow channel 10. When the washing device is working normally, the reversing element 30 connects the inlet flow channel 10 and the outlet flow channel 20. After the water entering the inlet flow channel 10 passes through the reversing element 40, it first passes through the first flow channel 21 and then passes through the second flow channel 22, thereby optimizing the flow channel of the water channel assembly 100. By optimizing the flow channel in the water channel assembly 100, the structure of the water channel assembly 100 is made compact.

[0050] Combine the following Figures 6 to 8 The waterway systems of some embodiments of the utility model are described.

[0051] The water system may further include an external water inlet pipe 210 and an internal water inlet pipe 220. The external water inlet pipe 210 may be configured to connect to a tap water source, and a water inlet valve 211 may be connected between the external water inlet pipe 210 and the faucet. The internal water inlet pipe 220 may be connected to the washing chamber and configured to pass water into the washing chamber. The water system may further include an internal drainage pipe 230 and an external drainage pipe 240. The internal drainage pipe 230 may be connected to the washing chamber and configured to discharge sewage from the inner cavity of the washing device. The external drainage pipe 240 may be connected to the sewer in the user's home.

[0052] Combination Figure 6 , wherein the direction of water flow when the water system is normally inflowing water is shown. When the washing device is working normally, the reversing element 40 can be in a working state, the first interface 41 and the second interface 42 are connected, so that the water inlet channel 10 and the water outlet channel 20 are connected, and water enters the water inlet channel 10 from the external water inlet pipe 210, flows to the water outlet channel 20, and then enters the washing chamber through the internal water inlet pipe 220.

[0053] Combination Figure 7, wherein the direction of water flow when the water system abnormally inflows water. Exemplarily, when the washing device is powered off, the reversing element 40 is in a power-off state, the reversing element 40 closes the water inlet channel 10 and the water outlet channel 20, the first interface 41 and the third interface 43 are connected, so that the water inlet channel 10 and the water outlet channel 30 are connected, and water enters the water inlet channel 10 from the external water inlet pipe 210, flows to the water outlet channel 30, and then is discharged to the sewer in the user's home through the external water outlet pipe 240.

[0054] Combination Figure 8 , wherein the path of washing and draining of the washing device is shown. After the washing device completes the washing work, the drainage pump of the washing device starts working, and the sewage in the inner cavity of the washing device enters the inner drainage pipe 230, and enters the water channel assembly 100, flows through the drainage channel 30, and then is discharged to the sewer of the user's home through the outer drainage pipe 240.

[0055] Among them, the internal drainage pipe 230 can be connected to a one-way valve 231 with a one-way conduction toward the outside of the washing chamber, which can prevent water in the drainage channel 30 from flowing into the washing chamber. That is to say, when the water system is abnormally filled with water, the water flows from the water inlet channel 10 into the drainage channel 30 and can be directly discharged into the sewer in the user's home, preventing the water from entering the washing chamber, so as to effectively protect the water system.

[0056] Combination Figure 2 and Figure 5 In some embodiments of the utility model, the water channel assembly 100 is provided with an air cavity 61, and the air cavity 61 is connected to the outer space of the water channel system. The water inlet channel 10 and / or the water outlet channel 30 are connected to the air cavity 61. Specifically, the water inlet channel 10 can be connected to the air cavity 61, or the water outlet channel 20 can be connected to the air cavity 61, or both the water inlet channel 10 and the water outlet channel 20 can be connected to the air cavity 61, so as to balance the pressure during washing or drainage.

[0057] In some embodiments of the utility model, the surface of the water system is provided with an inner tank interface 62 connected to the air cavity 61, wherein the inner tank interface 62 can be connected to the washing cavity. For example, when the washing device is working, water is introduced into the washing cavity through the water outlet channel 20. In order to improve the washing effect, the water introduced into the washing cavity can be heated in advance. When the water enters the washing cavity, a certain amount of steam will be formed. After the washing device completes the cleaning of the dishes, the water in the washing cavity needs to be drained. The air pressure balance of the washing cavity can be maintained through the air cavity 61, thereby improving the working stability of the dishwasher.

[0058] In some embodiments of the present invention, an air port 63 is provided on the surface of the water system, and the air port 63 is connected to the air cavity 61. The water system can be connected to the outside through the air port 63, thereby maintaining the air pressure balance of the water channel component 100 and avoiding the phenomenon of water backflow.

[0059] Combination Figure 2 In some embodiments of the utility model, the drainage channel 30 includes a first branch 31 and a second branch 32. One end of the first branch 31 is provided with a water inlet and the other end is connected to the second branch 32. One end of the second branch 32 is provided with a drain outlet and the other end is connected to the first branch 31. The first branch 31 and the second branch 32 have an angle, and the second branch 32 is connected to the air cavity 61.

[0060] Specifically, when the washing equipment is powered off, the reversing element 40 connects the water inlet channel 10 and the water outlet channel 30. Water that abnormally enters the water inlet channel 10 first enters the first branch 31 through the reversing element 40, then enters the second branch 32, and is discharged from the drain outlet. The first branch 31 and the second branch 32 can divert the water that abnormally enters the water inlet channel 10, fully utilize the space in the water channel assembly 100, and reduce the impact on the water channel assembly 100.

[0061] Furthermore, one end of the first branch 31 can be connected to the third interface 43, and the other end of the first branch 31 can be connected to the second branch 32. When the washing device is powered off, the first interface 41 of the reversing element 40 is connected to the third interface 43, and the water that abnormally enters the water inlet channel 10 directly enters the first branch 31 through the reversing element 40, and then enters the second branch 32, and is discharged from the drain port, so as to fully utilize the space in the water channel assembly 100 and improve the drainage efficiency of the washing device when water is abnormally inflowing.

[0062] In some embodiments of the utility model, the water channel assembly 100 is a respirator. It should be noted that the respirator is a component that balances the air pressure of the washing chamber of the washing device and the outside air pressure. Among them, the water inlet flow channel 10, the water outlet flow channel 20 and the drainage flow channel can be integrated into the respirator so that the water inlet flow channel 10, the water outlet flow channel 20 and the drainage flow channel 30 can be connected to the outside world, avoiding the backflow of water in the flow channel and improving the working stability of the washing device.

[0063] In some embodiments of the present invention, the reversing element 40 may be a three-way solenoid valve, which controls the switching of the valve by powering on and off, thereby controlling the direction of the water flow, simplifying the control method of the water system, and improving the reliability of the water system.

[0064] Exemplarily, the water channel assembly 100 may include an external drain pipe 240, which can be connected to the sewer in the user's home. The water discharged from the drainage channel 30 can enter the sewer in the user's home through the external drain pipe 240, thereby preventing water from continuously entering the washing device and causing overflow in the user's home when the washing device has abnormal water inflow.

[0065] The waterway assembly 100 may further include an inner drain pipe 230, which may be connected to the washing chamber. After the washing device completes the washing work, the water in the washing chamber may be discharged through the inner drain pipe 230. The inner drain pipe 230 may be connected to the drainage channel 30, and the inner drain pipe 230 may be connected to the washing chamber 30. Figure 8 , showing the flow direction of water in the washing equipment during the discharge of washing wastewater.

[0066] Among them, combined Figure 7 and Figure 8 The first branch 31 and the second branch 32 have an angle, which can guide the water entering the drainage channel 30, so that the water entering the drainage channel 30 is directly discharged from the sewer, avoiding abnormal water entering the washing device from entering the washing chamber, and reducing the impact on the washing device.

[0067] The washing device according to the embodiment of the utility model comprises the above-mentioned water system. The washing device of this embodiment adopts the technical solution of the above-mentioned embodiment, and thus has at least the beneficial effects brought by the technical solution of the above-mentioned embodiment, which will not be repeated here.

[0069] The various embodiments / implementations of the present invention can be combined with each other without causing any contradiction.

[0070] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.
