[0099] The application provides a water supply linkage system and a control method thereof, which can preferably solve the water use conflict problem caused by multi-point use of purified water.

[0100] Please refer to Figure 1 , Figure 2 and Figure 3 , the application provides a water supply linkage system, which can include: a water purifier 200, provided with a first water inlet 211 and a first water outlet 212, the first water inlet 211 can be communicated with a tap water supply end, and the first water outlet 212 can supply water to a water terminal; a cleaning machine 100, provided with a second water inlet 101, which can be communicated with the tap water supply end or the first water outlet 212; a controller 250, which can be communicatively connected with the cleaning machine 100 and the water purifier 200, and can obtain a water use signal of the cleaning machine 100 and an operating state of the water purifier 200, and after obtaining the water use signal of the cleaning machine 100, can control the timing of water inlet of the water purifier 200 to the cleaning machine 100 according to the operating state of the water purifier 200.

[0101] In the embodiment, the water supply linkage system can include a water purifier 200, a cleaning machine 100, and a controller 250 communicatively connected with the water purifier 200 and the cleaning machine 100.

[0102] Specifically, the water purifier 200 can output pure water externally. Specifically, as shown in Figure 1 , the water purifier 200 can be a single cold water purifier 200, which mainly includes a filtration system 270. The filtration system 270 can include: a pre-filter 201, a reverse osmosis filter 202, and a post-filter 203. Among them, the pre-filter 201 is mainly used to intercept relatively coarse particulate impurities, the reverse osmosis filter 202 is mainly used to prepare and obtain pure water, and the post-filter 203 is mainly used to further improve the taste of the pure water prepared and obtained by the reverse osmosis filter 202.

[0103] In addition, as shown in Figure 2 or Figure 3 , the water purifier 200 can be a double cold water purifier 200, which mainly includes a filtration system 270. The filtration system 270 can include: a pre-filter 201, a reverse osmosis filter 202, and a post-filter 203. Among them, the pre-filter 201 is mainly used to intercept relatively coarse particulate impurities, the reverse osmosis filter 202 is mainly used to prepare and obtain pure water, and the post-filter 203 is mainly used to further improve the taste of the pure water prepared and obtained by the reverse osmosis filter 202.As shown, the water purifier 200 can also be a cold and hot integrated machine. In addition to the above-mentioned filtering system 270, the cold and hot integrated machine can also include a heating system 280. The heating system 280 is used to heat the purified water after passing through the filtering system 270, so that the water purifier 200 can output water at a set temperature.

[0104] For the water purifier 200, a first water inlet 211 and a first water outlet 212 can be provided. The first water inlet 211 can be in communication with a tap water supply end. The tap water supply end can supply tap water to the water purifier 200 through the first water inlet 211. The first water outlet 212 can be connected to a water terminal, and can supply water to the water terminal, thereby meeting the user's demand for using purified water.

[0105] The water terminal can include a water faucet 300 provided with the water purifier 200, or a water using device in communication with the first water outlet 212, such as a pipeline machine or other device requiring purified water. Of course, the specific form of the water terminal can be different according to the specific composition of the water purifier 200, the use scene, etc., and the present application does not make specific limitations here.

[0106] The cleaning machine 100 can be a dishwasher, which is used to clean dishes, kitchenware, etc. The dishes can include bowls, plates, dishes, chopsticks, etc., and the kitchenware can include pots, basins, etc. In addition, the cleaning machine 100 can also be used to clean other types of articles, for example, when the cleaning machine 100 is used to clean clothes, it can correspond to a washing machine. In the embodiments of the present application, the cleaning machine 100 is mainly described with reference to a dishwasher, and other similar application scenarios can be referred to the present application, which will not be described one by one here.

[0107] The cleaning machine 100 can be provided with a second water inlet 101. The second water inlet 101 can be connected to a tap water supply end or can be connected to the first water outlet 212 of the water purifier 200.

[0108] The externally provided water is supplied into the cleaning machine 100 through the water inlet, thereby providing washing water for the cleaning machine 100. For a dishwasher, a water cup, an inner container in communication with the water cup, a washing pump, a spray arm, a drainage pump, a drainage port and the like are generally provided. The cleaning machine 100 generally includes multiple washing modes, such as a pre-washing mode, a strong washing mode, an energy-saving washing mode and the like. When the cleaning machine 100 enters a certain washing mode, a predetermined amount of water can be supplied into the water cup through the second water inlet 101; the washing pump is started, the water in the water cup is driven into the spray arm, and then sprayed to the cleaned object by the spray arm, thereby cleaning the cleaned object. The cleaned water is re-collected in the water cup under the action of gravity, thereby being reused. When a washing mode is ended, the drainage pump is started to pump out the water in the water cup, and finally discharged through the drainage port.

[0109] Generally, when the cleaning machine 100 is cleaned, the amount of water supplied into the inner container of the cleaning machine 100 is 3-5 liters, which can meet the washing demand. Accordingly, the time for single water supply into the inner container is short.

[0110] The second water inlet 101 can be in communication with the tap water supply end or in communication with the first water outlet 212. When the second water inlet 101 is in communication with the tap water supply end, the tap water supply end supplies tap water into the water cup through the second water inlet 101 for washing; when the second water inlet 101 is in communication with the first water outlet 212, the water purifier 200 supplies purified water into the water cup through the second water inlet 101 for washing.

[0111] The controller 250 can be in communication connection with the cleaning machine 100 and the water purifier 200, thereby interacting with the cleaning machine 100 and the water purifier 200. The controller 250 can be arranged in the cleaning machine 100; or the controller 250 is arranged in the water purifier 200; or the controller 250 is independently arranged; or the controller 250 is arranged in the cloud, and the water purifier 200 and the cleaning machine 100 are provided with a communication module.

[0112] When the controller 250 is arranged in the cleaning machine 100, the controller 250 can be an integrated controller 250 arranged in the cleaning machine 100 itself, such as a control chip of the cleaning machine 100. The controller 250 can communicate with the water purifier 200 in a wired or wireless manner. For example, when the controller 250 communicates with the water purifier 200 in a wireless manner, the water purifier 200 can be provided with a communication module, which communicates with the controller 250, thereby receiving the control signal sent by the controller 250 or feeding back the current state signal of the water purifier 200 to the controller 250.

[0113] When the controller 250 is arranged in the water purifier 200, the controller 250 can be arranged integrally in the water purifier 200, for example, on a control chip of the water purifier 200. The controller 250 can communicate with the cleaning machine 100 through wired or wireless communication. For example, when the controller 250 communicates with the cleaning machine 100 through wireless communication, the cleaning machine 100 can be provided with a communication module for communicating with the controller 250, so as to receive the control signal sent by the controller 250 or feed back the current state signal of the cleaning machine 100 to the controller 250.

[0114] When the controller 250 is arranged independently, the controller 250 can establish communication connection with the cleaning machine 100 and the water purifier 200 through wired or wireless communication. For example, the controller 250 can be a PLC controller arranged independently in the cleaning machine 100 and the water purifier 200. Of course, the specific form of the controller 250 is not limited to the above example, and the present application does not make specific limitation here. In addition, the installation position of the controller 250 can be flexibly arranged according to the installation environment of the user, and the present application does not make specific limitation here.

[0115] When the controller 250 is arranged in the cloud, the cloud can store a control program for controlling the operation of the water purifier 200 and the cleaning machine 100. The water purifier 200 and the cleaning machine 100 are provided with a communication module, and the water purifier 200 and the cleaning machine 100 can establish communication connection with the controller 250 in the cloud through the communication module, so as to receive the control signal sent by the controller 250 in the cloud or feed back the current state signal to the controller 250 in the cloud.

[0116] The controller 250 can obtain the water consumption signal of the cleaning machine 100 and the working state of the water purifier 200.

[0117] The working state of the water purifier 200 can include a water production state and a non-water production state. The water purifier 200 is provided with a working component capable of reflecting the working state of the water purifier 200. The working component is in communication connection with the controller 250, and the controller 250 can obtain the working state of the water purifier 200 according to the signal fed back by the working component.

[0118] The working component includes any one or a combination of the following: a water inlet electromagnetic valve 210 for controlling the water inlet of tap water; a combination valve 230 for controlling the discharge of concentrated water; and a water pump 240 for pressure boosting.

[0119] The working state of the water inlet electromagnetic valve 210, the combination valve 230 and the water pump 240 in the filter system 270 can be identified to determine whether the current water purifier 200 is in the water production state. Specifically, when the water inlet electromagnetic valve 210 is in the open state, or the combination valve 230 is in the open state, or the water pump 240 is in the running state, it can be indicated that the current water purifier 200 is in the water production state.

[0120] Of course, for different water purifiers 200, the working components that can be used to identify the water production state can be slightly different, which are not limited to the above description, and those skilled in the art can make other changes under the technical essence of the present application, as long as the functions and effects achieved are the same or similar to the present application, which should be covered within the protection scope of the present application.

[0121] In one embodiment, the water terminal includes any one or a combination of the following: a water outlet faucet 300, a pipeline machine, the water terminal is in communication connection with the controller 250, and the controller 250 can obtain the working state of the water purifier 200 according to the water signal of the water terminal.

[0122] In the present embodiment, the first water outlet 212 of the water purifier 200 can be connected to a water terminal, which can specifically include a water outlet faucet 300, a pipeline machine, etc. Of course, the specific form and number of the water terminal can be different according to the type of the water purifier 200, the used scene, etc., which are not limited to the above description, and those skilled in the art can make other changes under the technical essence of the present application, as long as the functions and effects achieved are the same or similar to the present application, which should be covered within the protection scope of the present application.

[0123] The controller 250 can be in communication connection with the water terminal, so that the water signal of the water terminal can be received, and the working state of the current water purifier 200 can be determined according to the water signal of the water terminal.

[0124] The corresponding water signal of the water terminal can be different for different types of water terminals, and the specific form of the water signal can be different according to the water terminal, which is not limited in the present application.

[0125] For example, when the water terminal is a water outlet faucet 300, a switch valve can be arranged at the water outlet faucet 300, when the switch valve is in the open state, it indicates that the current water terminal is in the water state, and the controller 250 can receive the water signal to determine that the current water purifier 200 is in the water production state.

[0126] In another embodiment, the water supply linkage system may further include a first detection unit that can communicate with the controller 250, the first detection unit being used to acquire the water usage signal of the water terminal.

[0127] In this embodiment, the water supply linkage system can also acquire the water usage signal of the water terminal by setting a first detection unit that is communicatively connected to the controller 250.

[0128] like Figure 3 As shown, the first detection unit may include any one or a combination of the following: pressure detection element 103, flow detection element 104, and solenoid valve 108.

[0129] When the water terminal is in use, pressure and flow rate fluctuations are generated in the pipeline connected to it. These fluctuations can be detected by pressure detector 103 and flow detector 104, thus reflecting the current water usage status of the water terminal. Furthermore, when the water terminal is in use, the solenoid valve can be in the open state; when the water terminal is not in use, the solenoid valve can be in the closed state. Therefore, the current water usage signal of the water terminal can be obtained by detecting the open / closed state of the solenoid valve.

[0130] Of course, the specific form of the first detection unit may vary depending on its specific location, detection principle, etc. The specific form of the first detection unit is not limited to the above description. Those skilled in the art may make other changes under the guidance of the technical essence of this application, but as long as the function and effect it achieves are the same as or similar to this application, they should be covered within the scope of protection of this application.

[0131] The first water outlet 212 is connected to the water terminal and the cleaning machine 100 via a pure water pipeline. The first detection unit is installed in the pure water pipeline between the first water outlet 212 and the water terminal. Since the first detection unit is mainly used to detect the water usage signal of the water terminal, it can be installed in the water outlet pipeline between the first water outlet 212 and the water terminal to reliably obtain the water usage signal of the water terminal by utilizing the pressure, flow rate, or valve status changes in the pipeline.

[0132] In one specific embodiment, the water terminal may include a water tap 300, the pure water pipeline includes a main pipeline 290 with one end connected to the first water outlet 212, and a plurality of branch pipelines branching off from the other end of the main pipeline 290, and the first detection unit is disposed in the main pipeline 290.

[0133] In the embodiment, the water terminal includes a water outlet faucet 300, which is communicatively connected to the controller 250. The controller 250 can obtain the water signal of the water outlet faucet 300. In addition, since the first detection unit is arranged in the main pipeline 290, the first detection unit can detect the water signal of the water outlet faucet 300 and the water signal of other branch pipelines connected to the main pipeline 290. In one scenario, when the first detection unit detects the fluctuation signal of the flow, but the controller 250 identifies that the water outlet faucet 300 does not generate the water signal, it can be determined that the washing machine 100 generates the water signal.

[0134] In addition, when the first detection unit is the flow detection piece 104 and the flow detection piece 104 is arranged in the main pipeline 290, the flow detection piece 104 can also measure the total water output of the water purifier 200, thereby facilitating accurate calculation of the filter core life.

[0135] After obtaining the water signal of the washing machine 100, the working state of the current water purifier 200 can be determined. If the current water purifier 200 is in the water making state, it indicates that the water terminal of the current water purifier 200 is in use. At this time, the water purifier 200 can be controlled to supply water to the washing machine 100 after the water terminal of the water purifier 200 finishes using water. In this way, the water terminal can avoid being affected by the water use of the washing machine 100 when the water terminal is in use, thereby avoiding the outflow being too small and affecting the user experience.

[0136] In one embodiment, the first water outlet 212 is connected to the water terminal and the washing machine 100 through a pure water pipeline. The pure water pipeline includes a main pipeline 290 connected to the first water outlet 212 at one end, and a plurality of branch pipelines branched from the other end of the main pipeline 290. The branch pipelines include a first branch 291 and a second branch 292. The washing machine 100 is connected to the first branch 291, and the water terminal is connected to the second branch 292.

[0137] In the embodiment, the water terminals of the washing machine 100 and the water purifier 200 are arranged in two different branches, respectively.

[0138] Further, the water supply linkage system can further include a second detection unit communicatively connected to the controller 250. The second detection unit can be used to obtain the water signal of the washing machine 100.

[0139] The second detection unit can be arranged on the first branch 291, thereby accurately obtaining the water signal of the washing machine 100.

[0140] Specifically, the second detection unit can include any one or a combination of the following: a pressure detection member 103 and a flow detection member 104.

[0141] In the present embodiment, the second detection unit is used to detect the water use signal of the cleaning machine 100. Specifically, the second detection unit can include at least one of the pressure detection member 103 and the flow detection member 104.

[0142] When the cleaning machine 100 has a water use demand, the water inlet valve of the cleaning machine 100 is opened, which will cause changes in pressure and flow at the second detection unit connected thereto. By arranging the second detection unit on the first branch 291, the changes in pressure and flow can be obtained. The controller 250 in communication connection with the second detection unit can identify whether the external device currently needs water based on the change signal of pressure and flow obtained by the detection unit. When it is identified that the cleaning machine 100 needs water, the water purifier 200 can be started to supply water to the cleaning machine 100.

[0143] In some embodiments, when the second detection unit includes the pressure detection member 103, the principle for detecting the water use signal of the cleaning machine 100 is as follows: when the water outlet faucet 300 of the water purifier 200 is in a closed state, if the cleaning machine 100 connected to the pure water pipeline of the water purifier 200 is opened, a pressure drop will occur at the position of the pressure detection member 103. The controller 250 can compare the pressure drop detected by the pressure detection member 103 with a preset pressure difference. When the pressure drop reaches the preset pressure difference, it indicates that the current cleaning machine 100 has a water use demand, and at this time the water purifier 200 can be started to produce water.

[0144] Specifically, the pressure detection member 103 can include any one of the following: a pressure sensor and a pressure switch. The working principle of the pressure switch is that when the pressure change at its position reaches a preset pressure difference, the pressure switch is switched from a first state to a second state, for example, from 0 to 1, and the current pressure fluctuation is detected. If the pressure fluctuation is lower than the preset pressure difference, the pressure switch cannot accurately measure it.

[0145] On the contrary, the pressure sensor can accurately obtain the change value of the current pressure, and has relatively higher control accuracy, and can detect the pressure signal under the condition of smaller pressure fluctuation.

[0146] Therefore, in the present embodiment, the pressure detection member 103 can be a pressure sensor. When the pressure detection member 103 includes a pressure sensor, when the control unit determines that the current pressure drop reaches a preset pressure drop based on the pressure signal detected by the pressure sensor, it indicates that the current cleaning machine 100 has a water use demand, and the water purifier is started to produce water.

[0147] When the pressure sensor detects that the current pressure is raised again above the preset pressure value, it can be indicated that the current cleaning machine 100 stops using water, at which time the water purifier can be closed and water production is stopped.

[0148] In some embodiments, when the second detection unit includes the flow detection piece 104, the specific form of the flow detection piece 104 can correspond to different forms according to different working principles, and the present application does not limit the specific form of the flow detection piece 104.

[0149] Specifically, the flow detection piece 104 can include a flow sensor. When the controller 250 determines that the current flow is greater than the preset flow based on the flow signal detected by the flow sensor, it indicates that the current cleaning machine 100 has a water demand, and the water purifier 200 is started.

[0150] For example, the flow sensor can be a water flow sensor, which mainly includes a copper valve body, a rotor assembly, a flow stabilizing assembly, and a Hall element. When the cleaning machine 100 has a water demand, it will open the water inlet valve of the cleaning machine 100. When the water inlet valve is opened, the water in the pure water outlet pipeline will flow to the cleaning machine 100 side. When the water flows through the rotor assembly, the magnetic rotor rotates, and the rotational speed changes linearly with the flow. The subsequent pulse signal output by the Hall element is fed back to the controller 250, and the controller 250 determines the size of the water flow. When the water flow reaches the preset flow, it indicates that the current cleaning machine 100 has a water demand, at which time the water purifier 200 can be started to produce water. When the water flow is lower than the preset flow, it indicates that the current cleaning machine 100 stops using water, at which time the water purifier 200 can be closed and water production is stopped.

[0151] In the embodiments of the present application, the pressure signal change state or change amount of the pressure switch or pressure sensor, and the signal state or specific flow threshold of the flow sensor are used to control the opening and closing of the cleaning machine 100. The water purifier 200 will not be frequently started due to large pipe resistance of the back-end pipeline or water pressure fluctuation of the user, which affects the service life of the water purifier 200 components (such as filter element).

[0152] In one embodiment, a one-way valve 106 is arranged upstream of the second detection unit.

[0153] The one-way valve 106 can be unidirectionally conducted along the water supply direction, specifically, the one-way valve 106 is unidirectionally conducted from the side of the water purifier 200 to the side of the cleaning machine 100. In the above case, the pressure upstream of the one-way valve 106 is small and cannot be conducted, thereby preventing the above case from generating interference signals to the second detection unit, and further preventing frequent false starts in the case that the water purifier 200 does not need to make water, and causing the filter element to alarm in advance.

[0154] The cleaning machine 100 is provided with a water inlet valve. In an embodiment, the water inlet valve can be in communication connection with the controller 250, and the controller 250 can determine the water use signal of the cleaning machine 100 based on the opening and closing state of the water inlet valve.

[0155] In the embodiment, the cleaning machine 100 is generally provided with a water inlet valve, which can be in communication connection with the control, and the opening and closing state of the water inlet valve can directly and reliably reflect the current water use signal of the cleaning machine 100. When the controller 250 receives the signal that the water inlet valve is opened, the current water use signal of the cleaning machine 100 can be obtained.

[0156] In an embodiment, the first branch 291 can be further provided with a three-way valve 500, the three-way valve 500 has a first interface connected with tap water, a second interface connected with the first branch 291, and a third interface for connecting the cleaning machine 100.

[0157] In the embodiment, the cleaning machine 100 can be connected with the water purifier 200, and the water purifier 200 can provide purified water to the cleaning machine 100 to perform purified water cleaning operation; or the cleaning machine 100 can be connected with tap water to perform general tap water cleaning operation. The three-way valve 500 can be arranged upstream of the second water inlet 101 of the cleaning machine 100, and the three-way valve 500 can include a first interface, a second interface and a third interface, wherein the first interface can be used as a water inlet for tap water, the second interface can be used as a water inlet for purified water, and the third interface can be used as a water outlet to supply the tap water or the water supplied by the water purifier 200 to the cleaning machine 100.

[0158] In an embodiment, the water supply linkage system can further include a water heater 400 in communication connection with the controller 250, and the water heater 400 can supply water at a set temperature to the cleaning machine 100.

[0159] In the embodiment, the water supply linkage system can further be provided with a hot water device 400, which can specifically be a device capable of providing hot water meeting the temperature requirement of the water end. Specifically, the hot water device 400 can be in the form of any water heater, such as a gas water heater, a wall-mounted stove, a heat pump, an electric water heater, a solar water heater, etc. The specific form of the hot water device 400 is not limited to the above description, and those skilled in the art can make other changes under the technical essence of the present application, as long as the functions and effects achieved are the same or similar to the present application, which should be covered within the protection scope of the present application.

[0160] The entire cleaning process of the cleaning machine 100 generally includes multiple processes. In the last rinsing process, the water purifier 200 can be used to provide clean water to the cleaning machine 100 for clean water washing, thereby improving the cleaning effect of the tableware. In the cleaning process before the rinsing process, the hot water device 400 can be used to provide hot water to the cleaning machine 100, which can reduce the cost of water consumption without consuming the filter element of the water purifier 200, and the water amount provided by the hot water device 400 is generally large, and the current hot water device 400 can generally provide hot water at a set temperature, which has high universality.

[0161] For the embodiment in which the water supply linkage system is provided with the hot water device 400, the three-way valve 500 can be replaced by a four-way valve, so as to supply water to the cleaning machine 100 according to the water requirement of the cleaning machine 100,

[0162] Based on the water supply linkage system provided in the above embodiment, the present application further provides a control method of the water supply linkage system, wherein the water supply linkage system mainly includes a water purifier 200, a cleaning machine 100, and a controller 250 capable of being communicatively connected with the water purifier 200 and the cleaning machine 100.

[0163] In the embodiment, the specific functions, connection relationships, etc. of the water purifier 200, the cleaning machine 100, and the controller 250 can be referred to the specific description of the water supply linkage system embodiment, which will not be described herein again.

[0164] Please refer to Figure 4 and Figure 5 The control method of the water supply linkage system can include the following steps:

[0165] Step S10: detecting a water use signal of the cleaning machine 100;

[0166] Step S11: detecting a current working state of the water purifier 200 when the water use signal of the cleaning machine 100 is identified; the working state of the water purifier 200 includes a water making state and a non-water making state;

[0167] Step S12: controlling the water purifier 200 not to supply water to the washing machine 100 when the water purifier 200 is in the water production state;

[0168] Step S13: controlling the water purifier 200 to supply water to the washing machine 100 when the water purifier 200 is in the non-water production state.

[0169] In the embodiment, the controller 250 in communication connection with the washing machine 100 and the water purifier 200 can continuously detect the working state of the washing machine 100, i.e. whether the washing machine 100 has the water use signal. Specifically, the water use signal of the washing machine 100 can be determined by the state of the water inlet valve at the second water inlet 101 of the washing machine 100, or can be determined by the detection signal obtained by the second detection unit arranged on the water inlet flow path in communication connection with the second water inlet 101 of the washing machine 100. The specific determination principle can be referred to the specific description of the water supply linkage system above, which will not be described herein again.

[0170] When the water use signal of the washing machine 100 is recognized, the working state of the water purifier 200 can be detected. The working state of the water purifier 200 includes the water production state and the non-water production state.

[0171] In an embodiment, the water purifier 200 is provided with a working component capable of reflecting the working state of the water purifier 200, and the working component is in communication connection with the controller 250. The detection of the working state of the water purifier 200 includes: obtaining the feedback signal of the working component, and determining the working state of the water purifier 200 according to the feedback signal of the working component.

[0172] In the embodiment, when the water purifier 200 is in the water production state, the working component inside the water purifier 200 can be used to reflect the working state of the water purifier 200. Specifically, the working component can include any one or a combination of the following: a water inlet electromagnetic valve 210 for controlling the water inlet of tap water; a combination valve 230 for controlling the discharge of concentrated water; and a water pump 240 for pressure boosting. The principle that the working component inside the water purifier 200 is used to reflect the working state of the water purifier 200 can be referred to the specific description of the water supply linkage system above, which will not be described herein again.

[0173] In one embodiment, the water purifier 200 is provided with a water outlet faucet 300, and detecting the current working state of the water purifier 200 includes: acquiring a water usage signal of the water outlet faucet 300, and when the water usage signal of the water outlet faucet 300 is detected, it indicates that the water purifier 200 is in a water production state; and when the water usage signal of the water outlet faucet 300 is not detected, it indicates that the water purifier 200 is in a non-water production state. That is, for the water purifier 200 provided with the water outlet faucet 300, since the water outlet faucet 300 can be electrically connected with the controller 250, the current working state of the water purifier 200 can be directly reflected by detecting the water usage signal of the water outlet faucet 300.

[0174] In addition, in other embodiments, the water supply linkage system can further include other water usage terminals, and the water purifier 200 can supply water to the water usage terminals, and detecting the current working state of the water purifier 200 includes: acquiring a water usage signal of the other water usage terminals, and when the water usage signal of the other water usage terminals is detected, it indicates that the water purifier 200 is in a water production state; and when the water usage signal of the other water usage terminals is not detected, it indicates that the water purifier 200 is in a non-water production state.

[0175] Specifically, the other water usage terminals can include any one of the following: a pipeline machine, an ice maker, a coffee machine, a water boiler, a humidifier, and a steaming oven. For each water usage terminal, it can be electrically connected with the controller 250, and each water usage terminal is provided with a working part indicating whether the current water usage terminal is in a water usage state, and by detecting the state of the working part, the controller 250 can identify the water usage signal of the current water usage terminal. Specifically, for each different water usage terminal, the form of the working part reflecting the current water usage state can be different, which will not be described one by one here.

[0176] In addition, for other water usage terminals, their specific forms are not limited to the above description, and those skilled in the art can make other changes under the technical essence of the present application, as long as the functions and effects achieved are the same or similar to the present application, which should be covered within the protection scope of the present application.

[0177] In one embodiment, the water purifier 200 is provided with a first water outlet 212, and a pure water pipeline connected to the first water outlet 212 for supplying pure water outwardly. The pure water pipeline includes a main pipeline 290 connected to the first water outlet 212 at one end, and a plurality of branch pipelines branched from the other end of the main pipeline 290. The water supply linkage system further includes a first detection unit communicatively connected to the controller 250, and the first detection unit is arranged on the main pipeline 290. The detection of the current working state of the water purifier 200 includes: acquiring the feedback signal of the first detection unit, and determining the current working state of the water purifier 200 according to the feedback signal of the detection unit.

[0178] In the present embodiment, the detection signal of the first detection unit in the main pipeline 290 can be used to determine whether the water purifier 200 is in the water production state. The specific form and detection principle of the first detection unit can be referred to the specific description of the water supply linkage system above, and will not be described here again.

[0179] In one embodiment, the water purifier 200 is provided with a water faucet 300 and / or the water supply linkage system is provided with other water terminal that can be supplied with water by the water purifier 200. The control method of the water supply linkage system further includes: continuously detecting the water signal of the water faucet 300 or other water terminal during the water purifier 200 supplies water to the washing machine 100; when the water signal of at least one of the water faucet 300 or other water terminal is acquired, controlling the water purifier 200 to pause supplying water to the washing machine 100, and then continuing to control the water purifier 200 to supply water to the washing machine 100 after the water signal stops.

[0180] That is, the control method of the water supply linkage system provided by the present application gives priority to the water demand of the water faucet 300 and other water terminal, and then supplies water to the washing machine 100 after there is no water demand in the above water terminal, so as to reliably solve the water conflict between the water demand of the washing machine 100 and the water demand of the above water terminal.

[0181] As shown in Figure 5 Further, the water supply linkage system can include a flow detection member 104 for detecting the water supply amount to the washing machine 100, and the flow detection member 104 is communicatively connected to the controller 250. The control method of the water supply linkage system can further include:

[0182] When the water purifier 200 pauses supplying water to the washing machine 100, the controller 250 determines the first water supply amount currently supplied to the washing machine 100 based on the flow signal acquired by the flow detection member 104;

[0183] When the water purifier 200 resumes water supply to the washing machine 100, the controller 250 determines a second water supply amount of the water purifier 200 to the washing machine 100 based on the target total water amount of the washing machine 100.

[0184] In the embodiment, the water amount supplied to the inner container of the washing machine 100 during washing is a fixed value, i.e., the target total water amount. The target total water amount is the water amount that meets the washing requirement by one-time water supply. The target total water amount can be stored in the controller 250.

[0185] During the water supply process of the water purifier 200 to the washing machine 100, if the water outlet faucet 300 or other water terminal of the water purifier 200 has water use, thereby interrupting the water supply to the washing machine 100, the first water supply amount before interruption can be obtained by setting the flow detection member 104, and the second water supply amount required to flow to the washing machine 100 after interruption can be determined by the controller 250, so as to accurately supply the target total water amount to the water cup.

[0186] As shown in FIG. 1, the water supply linkage system includes a flow detection member 104 for detecting the water supply amount to the washing machine 100. When the water purifier 200 supplies water to the washing machine 100, the control method of the water supply linkage system further includes: Figure 5 During the water supply process of the water purifier 200 to the washing machine 100, the water supply amount to the washing machine 100 is determined based on the flow signal detected by the flow detection member 104;

[0187] The water supply amount is compared with the target total water amount of the washing machine 100;

[0188] When the water supply amount does not reach the target total water amount, the water purifier 200 continues to produce water;

[0189] When the water supply amount reaches the target total water amount, the water purifier 200 stops producing water.

[0190] In the embodiment, the water amount supplied to the inner container of the washing machine 100 during washing is a fixed value, i.e., the target total water amount. The target total water amount is the water amount that meets the washing requirement by one-time water supply. The target total water amount can be stored in the controller 250.

[0191]

[0192] ​In the process that the water purifier 200 supplies water to the washing machine 100, the current water supply amount to the washing machine 100 can be obtained by setting the flow detection member 104, and the controller 250 can compare the current water supply amount with the target total water amount. When the water supply amount does not reach the target total water amount, the water purifier 200 continues to produce water; when the water supply amount reaches the target total water amount, the water purifier 200 stops producing water, so that the target total water amount is accurately supplied to the cup, and the shutdown time of the water purifier 200 is accurately controlled.

[0193] In an embodiment, the water use signal of the washing machine 100 can include water inlet temperature, the water purifier 200 includes a filtration system 270 and a heating system 280, and the water purifier 200 can output pure water at a set temperature; and the water purifier 200 supplies water to the washing machine 100 specifically by outputting pure water matching the water inlet temperature to the washing machine 100.

[0194] In the embodiment, the water use signal of the washing machine 100 can include water inlet temperature. For example, the washing machine 100 can include multiple washing modes, one of which includes warm water washing. The corresponding water inlet temperature is stored in the warm water washing mode. When the user selects this washing mode, the controller 250 can obtain the water inlet temperature signal.

[0195] For the water purifier 200, it can be a cold and hot integrated water purifier 200, including a filtration system 270 and a heating system 280. The heating system 280 is used to heat the pure water filtered by the filtration system 270, so that the water purifier 200 can output pure water at a set temperature.

[0196] For the washing machine 100 and the water purifier 200 in the above scenario, the water purifier 200 supplies water to the washing machine 100 specifically by outputting pure water matching the water inlet temperature to the washing machine 100. For example, the controller 250 obtains the current water inlet temperature signal as 50 degrees Celsius, and at this time, the heating system 280 of the water purifier 200 outputs pure water matching the temperature, so as to realize the pure water hot cleaning of the washing machine 100, and further improve the cleaning effect of the washing machine 100.

[0197] In an embodiment, the washing machine 100 has a resin life recording unit. When the water purifier 200 supplies water to the washing machine 100, the resin life recorded by the resin life recording unit does not change; when tap water supplies water to the washing machine 100, the resin life recorded by the resin life recording unit decreases.

[0198] In the present embodiment, the washing machine 100 can be provided with a soft water module, which can remove calcium and magnesium ions in tap water, reduce the hardness of tap water, and prevent scale formation on the surface of the washed tableware. The soft water module is provided with a resin life recording unit. When tap water flows into the washing machine 100 through the soft water module, the resin life recorded by the resin life recording unit decreases until the resin life is consumed. When the purified water machine 200 supplies water to the washing machine 100, the purified water machine 200 provides purified water, and the calcium and magnesium ions have been filtered and removed, so the resin life will not be consumed. Therefore, when the purified water machine 200 supplies water to the washing machine 100, the resin life recorded by the resin life recording unit can be controlled to remain unchanged, so that the resin life can be accurately accumulated, and the soft water module can be fully utilized without early warning.

[0199] In one embodiment, the purified water machine 200 automatically stops after starting water production for a predetermined length of time.

[0200] In the present embodiment, in order to prevent the purified water machine 200 from being unable to automatically stop under certain working conditions (for example, leakage occurs in the rear-end pipeline), an automatic stop protection function can be provided for the purified water machine 200. Specifically, the purified water machine 200 can be controlled to automatically stop after starting water production for a predetermined length of time. The predetermined length of time can be determined comprehensively according to the water consumption time of the water terminal, external equipment, and the like connected to the actual purified water machine 200, and the present application does not limit the specific numerical value.

[0201] In one specific embodiment, the water supply linkage system includes a purified water machine 200, a water heater, a washing machine 100, and a controller 250 communicatively connected to the purified water machine 200, the water heater, and the washing machine 100. The control method of the water supply linkage system includes:

[0202] When the water consumption signal of the washing machine 100 is recognized, the working state of the washing machine 100 is determined, and the working state includes a washing state and a rinsing state;

[0203] When the washing machine 100 is in the washing state, the water heater is controlled to supply water to the washing machine 100;

[0204] When the washing machine 100 is in the rinsing state, the working state of the purified water machine 200 is detected; the working state of the purified water machine 200 includes a water production state and a non-water production state;

[0205] When the purified water machine 200 is in the water production state, the purified water machine 200 is controlled not to supply water to the washing machine 100;

[0206] After the water purifier 200 is in the non-water production state, the water purifier 200 is controlled to supply water to the washing machine 100.

[0207] In the present embodiment, in addition to the water purifier 200 and the washing machine 100, a hot water device 400 can also be provided in the water supply linkage system.
