[0027] refer to Figure 1 The embodiment of the utility model first provides a dishwasher water supply system, including a water supply device 1, a turbidity detection device 3 and a control device.

[0028] The control device may be a main control MCU of the dishwasher, which is electrically connected to the water supply device 1 and the turbidity detection device 3 and can transmit electrical signals to each other.

[0029] The water supply device 1 includes a first water inlet pipe 11 and a second water inlet pipe 12, one end of the first water inlet pipe 11 is connected to a first water source, and the other end of the first water inlet pipe 11 is connected to a water tank water inlet 2 of the dishwasher; one end of the second water inlet pipe 12 is connected to a second water source, and the other end of the second water inlet pipe 12 is connected to a water tank water inlet 2; the use of the first water source and the second water source is determined by the control device in response to a water source selection instruction; the turbidity of the water supply of the first water source does not exceed the turbidity of the water supply of the second water source.

[0030] Specifically, the first water inlet pipe 11 is used to provide water from a first water source to the dishwasher, and the second water inlet pipe 12 is used to provide water from a second water source to the dishwasher. The first water source can be a tap in the user's home or a commonly used dishwasher water source, and the second water source can be other residual water for daily cleaning in the user's home, such as residual water from washing vegetables and fruits, or residual water after use in other scenarios. The water quality of these residual waters is not greatly affected and can be reused, so they serve as the second water source for the dishwasher.

[0031] The water supply device 1 connects the first water source / the second water source to the water tank inlet 2 of the dishwasher, that is, one end of the first water inlet pipe 11 is connected to the first water source, and the other end of the first water inlet pipe 11 is connected to the water tank inlet 2 of the dishwasher; one end of the second water inlet pipe 12 is connected to the second water source, and the other end of the second water inlet pipe 12 is connected to the water tank inlet 2. The user can select the water source to be used on the operation panel of the dishwasher, generate a water source selection instruction, and the control module of the dishwasher determines to use the first water source or the second water source in response to the water source selection instruction.

[0032] In a possible embodiment, the water supply device 1 also includes a first water inlet valve 13 and a second water inlet valve 14, the first water inlet valve 13 is arranged between the other end of the first water inlet pipe 11 and the water tank water inlet 2, and the second water inlet valve 14 is arranged between the other end of the second water inlet pipe 12 and the water tank water inlet 2.

[0033] Specifically, the first water inlet valve 13 is used to control the on-off of the first water inlet pipe 11. When the first water inlet valve 13 is opened, the first water inlet pipe 11 is connected to supply water from the first water source to the dishwasher. When the first water inlet valve 13 is closed, the first water inlet pipe 11 is disconnected, and the supply of water from the first water source to the dishwasher is stopped; the second water inlet valve 14 is used to control the on-off of the second water inlet pipe 12. When the second water inlet valve 14 is opened, the second water inlet pipe 12 is connected to supply water from the second water source to the dishwasher. When the second water inlet valve 14 is closed, the second water inlet pipe 12 is disconnected, and the supply of water from the second water source to the dishwasher is stopped.

[0034] In a possible implementation, the water supply device 1 further includes a water pump 15, which is disposed between the other end of the second water inlet pipeline 12 and the second water inlet valve 14. When the control device determines that the second water source supplies water in response to the user's water source selection instruction, the water pump 15 is controlled to start.

[0035] Specifically, since the second water source is a non-fixed water source and does not have pressure like tap water, a water pump 15 is provided on the second water inlet pipeline 12 to extract water from the second water source. It should be noted that the water pump 15 is provided between the other end of the second water inlet pipeline 12 and the second water inlet valve 14, that is, the water from the second water source first passes through the water pump 15 and then passes through the second water inlet valve 14. The water pump 15 is first turned on to confirm that the water from the second water source can be used, and then the second water inlet valve 14 is turned on.

[0036] Since the first water source is tap water and the second water source is clean residual water, the turbidity of the water supplied by the first water source does not exceed the turbidity of the water supplied by the second water source. When the second water source is used, the turbidity can be detected by the turbidity detection device 3 to ensure the cleaning effect.

[0037] The turbidity detection device 3 is arranged on the second water inlet pipeline 12, and is used to detect the turbidity of the water supply of the second water source, and generate turbidity detection information and send it to the control device, so that the control device controls the opening and closing of the second water source based on the turbidity detection information.

[0038] Specifically, the turbidity detection device 3 is used to detect the turbidity of the second water source, and turbidity detection information is generated and sent to the control device. If the turbidity detection information indicates that the turbidity of the second water source is not suitable for washing dishes, the second water source is controlled to be closed; if the turbidity detection information indicates that the turbidity of the second water source is suitable for washing dishes, the second water source is controlled to be turned on to continue to supply water to the dishwasher.

[0039] In a possible implementation, the turbidity detection device 3 is a turbidity sensor, which is disposed between the water pump 15 and one end of the second water inlet pipe 12. Specifically, the water from the second water source is firstly detected by the turbidity sensor during the process of being pumped into the dishwasher by the water pump 15, and the control device determines whether the turbidity of the liquid in the second water source is greater than a preset turbidity threshold based on the turbidity detection information.

[0040] In a possible implementation, when the control device determines based on the turbidity detection information that the turbidity of the liquid in the second water source is greater than the preset turbidity threshold, the water pump 15 is controlled to be closed, that is, it is determined that the water from the second water source is not suitable for washing dishes, and the water pump 15 is directly closed. At this time, the second water inlet valve 14 has not been opened, and no water flows into the dishwasher, which will not affect the cleaning effect. Further, when the control device determines based on the turbidity detection information that the turbidity of the liquid in the second water source does not exceed the preset turbidity threshold, the second water inlet valve 14 is controlled to be opened, and the water from the second water source enters the dishwasher. For the selection of the preset turbidity threshold, in some embodiments, it can be set to 5NTU (turbidity unit), and can be set to other values ​​according to actual needs, which is not limited here.

[0041] In addition, in order to improve the user experience and enable the user to more intuitively determine that the second water source is available, a voice prompt module can also be set. When the control device determines that the liquid turbidity of the second water source is greater than the preset turbidity threshold based on the turbidity detection information, the voice prompt module is driven to work. The voice prompt module plays voice prompt information such as "water quality does not meet the requirements" in a loop, and at the same time controls the water pump 15 to shut down.

[0042] When the control device determines that the water supply flow rate reaches a preset threshold, the control device controls the water supply device 1 to stop supplying water and starts the cleaning program. In a possible implementation, it also includes a water volume detection device 4, which is arranged between the water supply device 1 and the water tank water inlet 2; the water volume detection device 4 is used to detect the water supply flow rate from the water supply device 1 to the water tank water inlet 2, and generate water volume detection information and send it to the control device, so that when the control device determines that the water supply flow rate reaches a preset threshold, the control device controls the water supply device 1 to stop supplying water and start the cleaning program. Furthermore, when the second water source is used for water supply, when the control device determines that the water supply flow rate reaches a preset threshold, the control device controls the water pump 15 and the second water inlet valve 14 to close and starts the cleaning program.

[0043] Specifically, the water volume detection device 4 may be a Hall sensor. The water volume detection device 4 detects that water enters the water tank of the dishwasher, and the flow rate signal detected by the Hall sensor is transmitted to the control device, which determines the water supply flow rate. When the water supply flow rate reaches a preset threshold, the first water inlet valve 13 / the second water inlet valve 14 and the water pump 15 are closed, and the cleaning program is started.

[0044] In a possible implementation, a water softener 5 is further included, and the water softener 5 is disposed between the water supply device 1 and the water tank inlet 2. The water supplied by the water supply device 1 enters the water tank inlet 2 after passing through the water softener 5. Specifically, the water provided by the water supply device 1 is first softened by the water softener 5 and then enters the water tank of the dishwasher to extend the service life of the machine.

[0045] In another aspect, a dishwasher is provided, comprising the dishwasher water supply system as described above.

[0046] Next, the use logic of the above dishwasher water supply system is introduced, including the following steps:

[0047] The user selects the water source to be used on the program end of the dishwasher and generates a water source selection instruction. The control module of the dishwasher responds to the water source selection instruction and determines to use the first water source or the second water source. If the first water source, that is, the tap, is selected as the water source, the first water inlet valve 13 is controlled to open. Under the pressure of the tap, water is pressed into the water softener 5 for softening, and enters the water tank of the dishwasher after passing through the water volume detection device 4. The water volume detection device 4 detects the water supply flow of the first water source and generates water volume detection information to send to the control device. The control device determines the water supply flow. When the water supply flow reaches the preset threshold, the first water inlet valve 13 is closed and the cleaning program is started.

[0048] If the second water source, i.e., the clean residual water at home, is selected, the water pump 15 is controlled to start first, and the water from the second water source flows through the turbidity detection device 3 through the second water inlet pipe 12. The turbidity detection device 3 performs turbidity detection and generates turbidity detection information and sends it to the control device. The control device determines whether the second water source is suitable for washing dishes based on the turbidity detection information. When the control device determines that the turbidity of the liquid in the second water source is greater than the preset turbidity threshold based on the turbidity detection information, the voice prompt module is driven to work, and the voice prompt module plays the voice prompt information such as "water quality does not meet the requirements" in a loop, and at the same time The water pump 15 is controlled to be closed; when the control device determines that the liquid turbidity of the second water source does not exceed the preset turbidity threshold based on the turbidity detection information, the second water inlet valve 14 is controlled to be opened, and the water from the second water source enters the dishwasher, and the water is pumped into the water softener 5 for softening, and enters the water tank of the dishwasher after passing through the water quantity detection device 4. The water quantity detection device 4 detects the water supply flow of the second water source, and generates water quantity detection information and sends it to the control device. The control device determines the water supply flow. When the water supply flow reaches the preset threshold, the second water inlet valve 14 and the water pump 15 are closed, and the cleaning program is started.

[0049] Through the above embodiments, the dishwasher water supply system of the utility model is provided with a first water inlet pipeline and a second water inlet pipeline, the first water inlet pipeline is used to provide water from a first water source to the dishwasher, and the second water inlet pipeline is used to provide water from a second water source to the dishwasher, the second water source can be other residual water for daily cleaning at the user's home, and a turbidity detection device is provided to detect the turbidity of the water supply of the second water source, and generate turbidity detection information to be sent to the control device, if the turbidity detection information indicates that the turbidity of the second water source is not suitable for washing dishes, the second water source is controlled to be closed; if the turbidity detection information indicates that the turbidity of the second water source is suitable for washing dishes, the second water source is controlled to be turned on to continue to supply water to the dishwasher. The user can select the first water source / second water source according to actual needs, so that the residual clean water in life can be effectively utilized, water resources can be saved, and the dishwasher can continue to be used when the water supply at home is cut off, thereby improving the user experience.
