[0042] In the dishwasher's water flow system, washing water is added to the dishwasher chamber by opening the inlet valve, and the washing water in the dishwasher chamber is discharged to the drain pipe by opening the drain valve. The opening and closing of the inlet valve and the drain valve are controlled by a control device to create a suitable washing environment in the dishwasher chamber.
[0043] When the inlet valve, which is in the open position, malfunctions and cannot close properly, the drain valve, adjusted to the open position by the control device, allows water in the dishwasher chamber to flow into the drain pipe, thus preventing excessive water from overflowing from the dishwasher chamber. However, if the drain valve also malfunctions and cannot open properly, excessive water will flow into the dishwasher chamber and cause it to overflow.
[0044] To address the aforementioned problems, this application discloses a water flow system for a dishwasher.
[0045] Figure 1 This is a schematic diagram of a water flow system for a dishwasher provided in an embodiment of this application. Figure 1 ,like Figure 1 As shown, the water flow system 1 includes a water distribution valve 11, a first inlet pipe 12, a first drain pipe 13, a water level detection device 14, and a control device 15. The water distribution valve 11 includes an inlet 111, a first outlet 112, and a second outlet 113. The inlet 111 is connected to the first inlet pipe 12, the first outlet 112 is connected to the dishwasher chamber 2, and the second outlet 113 is connected to the first drain pipe 13. The water level detection device 14 and the water distribution valve 11 are electrically connected to the control device 15. The water level detection device 14 is used to detect the water level in the dishwasher chamber 2. The control device 15 is used to control the water distribution valve 11 to connect the inlet 111 to the first outlet 112 when the water level in the dishwasher chamber 2 is lower than a preset height, and to control the water distribution valve 11 to connect the inlet 111 to the second outlet 113 when the water level in the dishwasher chamber 2 is higher than the preset height.
[0046] In this embodiment of the application, by controlling the water inlet 111 in the water distribution valve 11 to connect to the first water outlet 112 or the second water outlet 113, the water flow can be controlled to flow to the dishwasher chamber 2 or the drain pipe, thereby avoiding the overflow of water in the dishwasher chamber 2 and the problem of flooding.
[0047] Figure 2 This is a schematic diagram of a water flow system for a dishwasher provided in an embodiment of this application. Figure 2 ,like Figure 2 As shown, the water flow system 1 also includes a water inlet valve 16, a second water inlet pipe 17, a drain valve 18, and a second drain pipe 19. The two ends of the first water inlet pipe 12 are connected to the water inlet valve 16 and the water inlet 111 of the water distribution valve 11, respectively. The two ends of the second water inlet pipe 17 are connected to the first water outlet 112 of the water distribution valve 11 and the dishwasher chamber 2, respectively. The two ends of the second drain pipe 19 are connected to the dishwasher chamber 2 and the drain valve 18, respectively.
[0048] In this embodiment, the water inlet valve 16 and the drain valve 18 are electrically connected to the control device 15. The control device 15 can control the opening and closing of the water inlet valve 16, thereby adding water to or stopping the addition of water to the dishwasher chamber 2. The control device 15 can also control the opening and closing of the drain valve 18, thereby draining water from the dishwasher chamber 2 or preventing water from draining from the dishwasher chamber 2.
[0049] In this embodiment, the water distribution valve 11 is electrically connected to the control device 15. By adjusting the water distribution valve 11 through the control device 15, the inlet 111 of the water distribution valve 11 can be connected only to the first outlet 112, and not to the second outlet 113. Similarly, by adjusting the water distribution valve 11 through the control device 15, the inlet 111 of the water distribution valve 11 can also be connected only to the second outlet 113, and not to the first outlet 112.
[0050] In this embodiment, when the inlet 111 of the water distribution valve 11 is only connected to the first outlet 112, the water flowing into the water distribution valve 11 from the inlet 111 will flow out from the first outlet 112 and into the dishwasher chamber 2. Connecting the inlet 111 of the water distribution valve 11 to the first outlet 112 is suitable when the inlet valve 16 and / or drain valve 18 in the water flow system 1 can be opened or closed normally, allowing the water source to flow normally into the dishwasher chamber 2 without preventing water from overflowing from the dishwasher chamber 2.
[0051] In this embodiment, when the inlet 111 of the water distribution valve 11 is only connected to the second outlet 113, the water entering the water distribution valve 11 from the inlet 111 will flow out from the second outlet 113 and into the first drain pipe 13. Connecting the inlet 111 of the water distribution valve 11 to the second outlet 113 is suitable for situations where the inlet valve 16 and the drain valve 18 in the water flow system 1 cannot be opened or closed normally, thus preventing water from overflowing from the dishwasher chamber 2 and causing flooding.
[0052] In some possible embodiments, the water distribution valve 11 includes a valve body and a base. The base is connected to the valve body. A drive mechanism is disposed inside the base, and a through hole communicating with the interior of the valve body is provided on the base. The top of the valve body is provided with an inlet 111, a first outlet 112, a second outlet 113, and a positioning post coaxially aligned with the through hole. A water distribution plate is disposed inside the valve body. The water distribution plate includes a rotating shaft and a baffle plate, and the baffle plate is fixedly disposed at the end of the rotating shaft. One end of the rotating shaft with the baffle plate is connected to the positioning post, and the other end of the rotating shaft is inserted into the through hole of the base and connected to the drive mechanism.
[0053] In some possible embodiments, the control device 15 is electrically connected to the drive mechanism. The control device 15 can control the drive mechanism to rotate the water divider, thereby controlling the water divider to block the first outlet 112 or the second outlet 113. When the water divider blocks the first outlet 112, the inlet 111 of the water divider valve 11 is connected to the second outlet 113; when the water divider blocks the second outlet 113, the inlet 111 of the water divider valve 11 is connected to the first outlet 112.
[0054] In some possible embodiments, the water distribution valve 11 includes a position detector. The position detector is electrically connected to the control device 15. The position detector is used to detect the position of the baffle and transmit the position information of the baffle to the control device 15. The control device 15 adjusts the position of the baffle according to the acquired position information of the baffle and the actual needs, so that the baffle blocks the first outlet 112 or the second outlet 113.
[0055] In this embodiment, the water level detection device 14 is electrically connected to the control device 15. The water level detection device 14 can detect the water level in the dishwasher chamber 2 to determine if the water level is too high and overflow is possible. The water level detection device 14 transmits the detected water level to the control device 15, which then controls the water distribution valve 11 based on the acquired water level, connecting the inlet 111 of the water distribution valve 11 to either the first outlet 112 or the second outlet 113.
[0056] In this embodiment, the water flow direction in the water distribution valve 11 is determined based on a preset height. When the water level in the dishwasher chamber 2 is lower than the preset height, the control device 15 controls the water distribution valve 11 to connect the inlet 111 to the first outlet 112. When the water level in the dishwasher chamber 2 is higher than the preset height, the control device 15 controls the water distribution valve 11 to connect the inlet 111 to the second outlet 113. The user can adjust the preset height according to their personal standards to prevent the water level in the dishwasher chamber 2 from becoming too high.
[0057] In one optional embodiment, the water level height is directly obtained by the water level detection device 14, and the water level height is compared with the preset height to determine whether the control device 15 needs to control the water distribution valve 11 to adjust the water flow direction.
[0058] In another alternative embodiment, it is not necessary to use the water level detection device 14 to obtain the water level height; it is sufficient to use the water level detection device 14 to determine whether the water level height has reached the preset height.
[0059] In some possible embodiments, a water level probe is provided in the water level detection device 14, extending into one end of the dishwasher chamber 2 and adjacent to the top of the dishwasher chamber 2. The water level probe typically operates using the conductivity of water, and its working principle is mainly based on electrical principles. When the water level rises and contacts the water level probe, the circuit is connected, indicating that the water level has reached a preset height, and this signal is transmitted to the control device 15.
[0060] In some possible embodiments, the water level detection device 14 is a float-type water level sensor. Utilizing the principle that the buoyancy of the float rises and falls with the water level, the change in water level is converted into an electrical signal output through the interaction of an internal magnet and an external reed switch. When the water level rises, the float also rises, causing the magnet to approach the reed switch, closing or opening the contacts inside the reed switch, thereby sending a signal indicating the change in water level.
[0061] In some possible embodiments, the water level detection device 14 is a pressure sensor. The water level is indirectly determined by measuring the water pressure in the dishwasher chamber 2. When the water level rises, the water pressure also increases, and the pressure sensor converts this change into an electrical signal and sends it to the control device 15.
[0062] In some possible embodiments, the water level detection device 14 is a photoelectric liquid level sensor. Utilizing the photoelectric effect, it detects the water level by emitting and receiving light. When the water level is higher than the sensor's position, the light is blocked by the water, and the light signal received by the sensor weakens; when the water level is lower than the sensor's position, the light is not blocked by the water, and the light signal received by the sensor strengthens. The water level can be determined based on the changes in the light signal.
[0063] In some possible embodiments, the water flow system 1 includes a reminder device. The reminder device is electrically connected to the control device 15. When the water level in the dishwasher chamber 2 exceeds a preset height, the control device 15 can control the reminder device to issue a reminder signal to alert the user to the situation and, if necessary, shut off the main water supply valve to avoid wasting water resources.
[0064] In some possible embodiments, when the inlet valve 16 and / or the drain valve 18 loses control, the control device 15 can also control the reminder device to issue a reminder signal, so as to inform the user of the problem in the water flow system 1 in a timely manner and to repair the inlet valve 16 and / or the drain valve 18 in a timely manner.
[0065] This application also provides a dishwasher. The dishwasher includes the water flow system 1 and dishwasher chamber 2 described above. By providing the water flow system 1 in the dishwasher, excessive water flow in the dishwasher chamber 2 can be prevented from overflowing from the dishwasher chamber 2 when the inlet valve 16 is open and out of control, and when the drain valve 18 is closed and out of control, thereby avoiding flooding problems.

Each embodiment focuses on describing the differences from other embodiments. In particular, the device embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions of the method embodiments.
