When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

The disclosed embodiment provides a water purifier 10, as shown in fig. 1, the water purifier 10 includes a purification module 101, a hot water pipeline 102, a cold water pipeline 103, a controller (not shown in the drawings of the present disclosure), and a water outlet unit 105; the purification module 101 comprises a hot water outlet 1011 and a cold water outlet 1012; the hot water pipeline 102 is provided with a hot water storage tank 1021, a heating device 1022 and a hot water switch 1023; the cold water pipeline 103 is provided with a cold water switch 1033, and the water outlet unit 105 includes a regulating assembly 1051 and a water outlet pipe 1052.

Wherein, the hot water outlet 1011 of the purification module 101 is connected with the hot water pipeline 102, the cold water outlet 1012 is connected with the cold water pipeline 103, and the purification module 101 is used for obtaining purified water and outputting the purified water to the hot water pipeline 102 and the cold water pipeline 103 respectively.

The hot water pipeline 102 and the cold water pipeline 103 are both connected with the water outlet unit 105, and the heating device 1022 is arranged in cooperation with the hot water storage tank 1021 and is used for heating purified water stored in the hot water storage tank 1021; the hot water line 102 is used to supply hot water in the hot water storage tank 1021 to the water outlet unit 105, and the cold water line 103 is used to supply purified water output by the purification module 101 to the water outlet unit 105.

The adjusting assembly 1051 is used for determining the target water temperature of the water flow to be output from the water pipe 1052;

the controller is respectively connected to the adjusting assembly 1051, the hot water switch 1023 and the cold water switch 1033, and is used for controlling the hot water switch 1023 and the cold water switch 1033 according to the target water temperature, so that the temperature of the water flow output by the water outlet pipe 1052 meets the target water temperature.

For example, the purification module 101 may be connected to a pipeline of municipal water supply for purifying tap water supplied from the municipal water supply such that the quality of the tap water meets safety standards. Because the hot water storage tank 1021 is arranged on the hot water pipeline 102, part of purified water provided by the purification module 101 can be stored in advance, when it is detected that water is stored in the hot water storage tank 1021, the controller instructs the heating device 1022 to heat the purified water in the hot water storage tank 1021 to a preset temperature threshold, and the preset temperature threshold can be adjusted according to actual conditions. Specifically, the heating device 1022 is connected to a controller, and the controller can adjust the heating power of the heating device 1022 according to the preset temperature threshold.

When the user needs to use the purified water at the target water temperature, the user may first operate the regulating unit 1051 such that the parameter indicated by the regulating unit 1051 is the desired target water temperature. The adjustment assembly 1051 may be a button, a knob, a slider, etc., and is not limited in this disclosure. If the adjusting assembly 1051 is a button, the user can press the button corresponding to the target water temperature, and the parameter indicated by the adjusting assembly 1051 is the target water temperature; if the adjusting assembly 1051 is a knob, the user can rotate the adjusting assembly 1051 to rotate the indicating mark of the adjusting assembly 1051 to the position of the target water temperature, and the parameter indicated by the adjusting assembly 1051 is the target water temperature; if the adjusting assembly 1051 is a slider, the user can slide the slider to make the indication mark of the slider slide to the position of the target water temperature, and the parameter indicated by the adjusting assembly 1051 is the target water temperature.

After the user finishes operating the adjusting assembly 1051, the controller can control the hot water switch 1023 and the cold water switch 1033 according to the target water temperature indicated by the adjusting assembly 1051, i.e. adjust the opening degree of the hot water switch 1023 and the cold water switch 1033, when the hot water switch 1023 is opened, the hot water pipeline 102 outputs the hot water in the hot water storage tank 1021 to the water outlet pipe 1052, and when the cold water switch 1033 is opened, the cold water pipeline 103 outputs the purified water output by the purifying module 101 to the water outlet pipe 1052 (at this time, the purifying module 101 starts to work). The hot water output from the hot water pipeline 102 is mixed with the cold water output from the cold water pipeline 103 at the water outlet pipe 1052, so that the temperature of the water flow finally output from the water outlet pipe 1052 meets the target water temperature.

Specifically, the hot water switch 1023 and the cold water switch 1033 can be electromagnetic valves or mechanical valves, and the controller can control the opening, closing, opening degree and the like of the hot water switch 1023 and the cold water switch 1033 through stepping motors connected with the other two switches.

Alternatively, as shown in fig. 2, the heating device 1022 may be wrapped outside the hot water storage tank 1021, and heat is transferred to the water stored in the hot water storage tank 1021 by heating the tank body of the hot water storage tank 1021, so as to heat the water. In practical applications, the length of the heating device 1022 wrapped around the hot water storage tank 1021 may be set according to specific situations, which is not limited in the embodiments of the present disclosure. Optionally, the heating device 1022 may also be disposed in the hot water storage tank 1021.

In the technical solution provided by the embodiment of the present disclosure, the water purifier 10 can control the cold water switch 1033 and the hot water switch 1023 by controlling, so that the water output by the water outlet pipe 1052 of the water outlet unit 105 meets the target water temperature expected by the user, the convenience of water temperature control of the water purifier 10 is improved, and further the user experience is improved.

In one embodiment, as shown in fig. 3, the cold water line 103 is provided with a cold water storage tank 1031 for storing purified water output by the purification module 101.

For example, when the controller controls the cold water switch 1033 to be turned on, the cold water pipeline 103 may output purified water stored in the cold water storage tank 1031 to the water outlet pipe 1052, and the purified water is mixed with hot water output from the hot water pipeline 102 at the water outlet pipe 1052, so that the temperature of the water flow finally output from the water outlet pipe 1052 meets the target water temperature. When purified water stored in the cold water storage tank 1031 is used to supply water to the water outlet pipe 1052, the purification module 101 may not work temporarily, and when the water in the cold water storage tank 1031 is lowered to a minimum threshold value, the purification module 101 may work again, so that the opening times of the purification module 101 is reduced, and the service life of the purification module 101 is prolonged.

In one embodiment, as shown in FIG. 4, the hot water line 102 is provided with a first temperature sensor 1024 for detecting the hot water temperature of the hot water line 102. The cold water line 103 is provided with a second temperature sensor 1034 for detecting the cold water temperature of the cold water line 103. The first temperature sensor 1024 and the second temperature sensor 1034 are respectively connected with the controller; the controller is used for controlling the hot water switch 1023 and the cold water switch 1033 according to the target water temperature, the hot water temperature and the cold water temperature, so that the temperature of the water flow output by the water outlet pipe 1052 meets the target water temperature.

For example, after the controller obtains the target water temperature determined by the regulating assembly 1051, the controller can also obtain the hot water temperature of the hot water pipe 102 detected by the first temperature sensor 1024 and the cold water temperature of the cold water pipe 103 detected by the second temperature sensor 1034, respectively, and then control the opening degree of the hot water switch 1023 and the cold water switch 1033 according to the target water temperature. For example, if the hot water temperature is lower than the target water temperature, the controller may first instruct the heating device 1022 to heat the purified water stored in the hot water storage tank 1021, so that the temperature of the purified water stored in the hot water storage tank 1021 is the same as the target water temperature, at which time the controller may instruct the hot water switch 1023 to be turned on, the cold water switch 1033 to be turned off, and at which time the temperature of the water flow output by the water outlet pipe 1052 can meet the target water temperature. If the target water temperature is the same as the cold water temperature, the controller 104 can instruct the hot water switch 1023 to close and the cold water switch 1033 to open. If the target water temperature is between the hot water temperature and the cold water temperature, the controller may calculate a mixing ratio of hot water and cold water according to a difference between the target water temperature and the hot water temperature and a difference between the target water temperature and the cold water temperature, and then control the opening degrees of the hot water switch 1023 and the cold water switch 1033 such that the hot water and the cold water output to the water outlet pipe 1052 correspond to the mixing ratio.

In one embodiment, as shown in FIG. 5, the outlet pipe 1052 is provided with a third temperature sensor 1053 connected to the controller for sensing the actual temperature of the water flow output from the pipe 1052. The controller is used for controlling the hot water switch 1023 and the cold water switch 1033 according to the target water temperature and the actual temperature, so that the temperature of the water flow output by the water outlet pipe 1052 meets the target water temperature.

For example, when there is water flow through the outlet pipe 1052, the third temperature sensor 1053 can detect the actual temperature of the water flow and feed the actual temperature back to the controller. The controller can determine whether the actual water temperature is the same as the target water temperature set by the user, and if so, the controller can keep the opening degree of the hot water switch 1023 and the cold water switch 1033 unchanged; if not, the opening degree of the hot water switch 1023 and the cold water switch 1033 can be adjusted according to the difference between the actual water temperature and the target water temperature. If the actual water temperature is higher than the target water temperature, the controller increases the opening degree of the cold water switch 1033 and decreases the opening degree of the hot water switch 1023; if the actual water temperature is lower than the target water temperature, the controller decreases the degree of opening of the cold water switch 1033 and increases the degree of opening of the hot water switch 1023.

In one embodiment, the adjustment assembly 1051 is also used to determine a target flow rate of water to be output from the outlet pipe 1052. The controller is also used to control the hot water switch 1023 and the cold water switch 1033 according to the target flow rate, so that the flow rate of the water flow output by the water outlet pipe 1052 is the same as the target flow rate.

For example, when a user needs to use a target flow rate of water, it may first determine whether the currently determined object of the regulating component 1051 is a flow rate, and if so, the regulating component 1051 may be operated such that the parameter indicated by the regulating component 1051 is the required target flow rate. If the adjusting component 1051 is a button, the user can press the button corresponding to the target flow, and the parameter indicated by the adjusting component 1051 is the target flow; if the adjusting assembly 1051 is a knob, the user can rotate the adjusting assembly 1051 to rotate the indicating mark of the adjusting assembly 1051 to the position of the target flow, and the parameter indicated by the adjusting assembly 1051 is the target flow; if the adjusting component 1051 is a slider, the user can slide the slider, so that the indication mark of the slider slides to the position of the target flow rate, and the parameter indicated by the adjusting component 1051 is the target flow rate.

After the user finishes operating the adjusting assembly 1051, the controller can control the hot water switch 1023 and the cold water switch 1033 according to the target flow rate indicated by the adjusting assembly 1051, that is, the opening degrees of the hot water switch 1023 and the cold water switch 1033 are adjusted, so that after the hot water output from the hot water pipeline 102 is mixed with the cold water output from the cold water pipeline 103 in the water outlet pipe 1052, the flow rate of the water flow finally output from the water outlet pipe 1052 meets the target flow rate.

In one embodiment, as shown in fig. 6, the outlet unit 105 further includes a switching assembly 1054. The switching unit 1054 is connected to the regulating unit 1051 and the controller, respectively, and is used for switching the determined object of the regulating unit 1051, including the water temperature or the flow rate.

Illustratively, the switching assembly 1054 can be a button disposed above the adjustment assembly 1051. When a user needs to use purified water at a target flow rate and a target water temperature, the user may first operate the regulating unit 1051, and by operating the regulating unit 1051, it may be determined whether the subject currently determined by the regulating unit 1051 is the water temperature or the flow rate. Assuming that the target of the adjustment module 1051 is the water temperature at the time of initial use, the user can first operate the adjustment module 1051 to determine the target water temperature, then press the switch module 1054, and after the switch module 1054 is pressed, the target of the adjustment module 1051 is switched to the flow rate, at which time the user can continue to operate the adjustment module 1051 to determine the target flow rate of the purified water to be used. After the target water temperature and the target flow rate are determined, the controller can control the hot water switch 1023 and the cold water switch 1033, that is, the opening degrees of the hot water switch 1023 and the cold water switch 1033 are adjusted, so that after the hot water output by the hot water pipeline 102 and the cold water output by the cold water pipeline 103 are mixed in the water outlet pipe 1052, the temperature of the water flow finally output by the water outlet pipe 1052 meets the target water temperature, and the flow rate meets the target flow rate.

In practical applications, the switching unit 1054 may not be provided, but the water temperature or the flow rate may be switched by performing a preset operation on the regulating unit 1051, for example, the switching unit 1051 may be pressed for a long time, which is not limited in the embodiment of the disclosure.

In one embodiment, as shown in fig. 7, the outlet unit 105 further includes a display screen 1055; the display 1055 is connected to the regulating assembly 1051 for displaying a target water temperature or a target flow rate.

For example, the user may operate the adjustment assembly 1051 when a target water temperature or a target flow rate of water is desired, at which time the display 1055 lights up and displays the value of the object currently determined by the adjustment assembly 1051. Taking the adjusting assembly 1051 as a knob as an example, when a user needs to use water with a target water temperature, the knob may be rotated, at this time, the display 1055 lights up and displays the object currently determined by the knob, if the display 1055 currently displays the word "35 ℃", it indicates that the object currently determined by the knob is temperature, at this time, the user may continue to rotate the knob until the temperature displayed on the display 1055 is expected, that is, the temperature displayed on the display 1055 is the target water temperature, and then the controller may control the opening degrees of the hot water switch 1023 and the cold water switch 1033, so that after the hot water output by the hot water pipeline 102 and the cold water output by the cold water pipeline 103 are mixed at the water outlet pipe 1052, the temperature of the water output by the water outlet pipe 1052 finally satisfies the target water temperature.

If the user currently desires to use the target flow of water and, upon rotating the knob, finds that the display 1055 currently displays the word "35 c", the user may first press the switch 1054, after the switch 1054 is pressed, the decision object of the knob is switched to flow, which is shown on the display 1055 as 0 (hot switch 1023 and cold switch 1033 are both closed), or the last user-set target flow rate, the user may rotate the knob until the flow rate displayed on the display 1055 is as desired, that is, the flow rate displayed on the display 1055 is the target flow rate, and then the controller can control the opening degree of the hot water switch 1023 and the cold water switch 1033 according to the target flow rate, after the hot water output from the hot water pipeline 102 and the cold water output from the cold water pipeline 103 are mixed in the water outlet pipe 1052, the flow rate of the water flow finally output from the water outlet pipe 1052 meets the target flow rate.

Similarly, if the user needs to use water with the target water temperature at present, and after the knob is rotated, it is found that the information currently displayed on the display screen 1055 is the flow rate, the user may first press the switching assembly 1054, after the switching assembly 1054 is pressed, the determined object of the knob is switched to the water temperature, at this time, the temperature of unheated water may be displayed on the display screen 1055, or the target water temperature set by the user last time, the user may continue to rotate the knob until the water temperature displayed on the display screen 1055 meets the expectation, that is, the flow rate displayed on the display screen 1055 is the target water temperature, and then the controller may control the opening degrees of the hot water switch 1023 and the cold water switch 1033, so that after the hot water output by the hot water pipeline 102 and the cold water output by the cold water pipeline 103 are mixed at the water outlet pipe 1052, the temperature of the water output by the outlet pipe 1052 finally meets the target water.

In one embodiment, as shown in fig. 8, the outlet unit 105 further includes a confirmation assembly 1056; the confirmation assembly 1056 is disposed in cooperation with the display 1055, and is connected to the controller, for obtaining a confirmation signal according to the displacement of the display 1055.

The controller is used for controlling the hot water switch 1023 and the cold water switch 1033 according to the target water temperature after the confirmation signal is acquired by the confirmation component 1056, so that the temperature of the water flow output by the water outlet pipe 1052 meets the target water temperature; or the hot water switch 1023 and the cold water switch 1033 are controlled according to the target flow rate, so that the flow rate of the water flow output by the water outlet pipe 1052 is the same as the target flow rate.

For example, when a user desires to use hot water at a target flow rate and a target water temperature, the user may first rotate the knob of the adjustment assembly 1051, whereupon the display screen 1055 lights up and displays the value of the object currently determined by the adjustment assembly 1051. Assuming that the display screen 1055 currently displays a 35 ℃ word at this time, it is described that the object determined by the knob is the temperature at this time, the user may continue to rotate the knob until the temperature displayed on the display screen 1055 is the target water temperature, then the user presses the switching module 1054, after the switching module 1054 is pressed, the object determined by the knob is switched to the flow rate, at this time, the flow rate set by the user last time is displayed on the display screen 1055, the user continues to rotate the knob until the flow rate displayed on the display screen 1055 is the target flow rate required at this time, then the user presses or dials the display screen 1055, the confirmation module 1056 provided in cooperation with the display screen 1055 may detect the displacement of the display screen 1055, and the confirmation signal may be obtained according to the displacement of the display screen 1055. After determining that the confirmation signal is obtained, the controller 1034 may control the opening degree of the hot water switch 1023 and the cold water switch 1033, so that the temperature of the water flow output by the water outlet pipe 1052 at this time meets the target water temperature, and the flow rate meets the target flow rate.

In practice, the adjustment assembly 1051, the display 1055, and the confirmation assembly 1056 may be disposed separately or in cooperation with each other, for example, as shown in FIG. 8, the display 1055 may be disposed above the adjustment assembly 1051 and the confirmation assembly 1056 may be disposed below the adjustment assembly 1051. The user can adjust the target water temperature or the target flow rate by rotating the adjusting assembly 1051, the display 1055 can display the target water temperature or the target flow rate, the display 1055 can be pressed downwards after the user selects the target water temperature or the target flow rate, the display 1055 generates downward displacement, and the confirming assembly 1056 arranged below the adjusting assembly 1051 immediately confirms to acquire the confirmation signal.

In practical applications, if the user does not select the target water temperature or the target flow rate, the confirmation module 1056 is directly operated, and at this time, the controller may control the opening degrees of the hot water switch 1023 and the cold water switch 1033 according to the preset default temperature and the default flow rate, and at this time, the temperature of the water flow output by the water outlet pipe 1052 meets the default water temperature, and the flow rate meets the default flow rate.

In one embodiment, as shown in FIG. 9, the outlet unit 105 further includes a flow sensor 1057 disposed in cooperation with the outlet pipe 1052. A flow sensor 1057 is connected to the controller for sensing the actual flow rate of water through the outlet pipe 1052. The controller is used to control the hot water switch 1023 and the cold water switch 1033 according to the actual flow rate and the target flow rate, so that the flow rate of the water flow output by the water outlet pipe 1052 is the same as the target flow rate.

For example, after the controller controls the opening degree of the hot water switch 1023 and the cold water switch 1033 according to the target flow rate set by the user, the flow sensor 1057 may detect the actual flow rate of the water flowing through the water outlet pipe 1052, and the controller may determine whether the actual flow rate is the same as the target flow rate set by the user. If the current opening degrees of the hot water switch 1023 and the cold water switch 1033 are the same, the controller maintains the opening degrees of the current hot water switch 1023 and the current cold water switch 1033 unchanged; if not, the controller 1034 may readjust the hot switch 1023 and the cold switch 1033 based on the difference between the actual flow rate and the target flow rate.

Optionally, if the temperature of the water flow output by the water outlet pipe 1052 required by the user meets the target water temperature and the flow rate meets the target flow rate, if the actual flow rate is different from the target flow rate set by the user, the controller needs to consider the water temperature of the finally output water flow when adjusting the opening degrees of the hot water switch 1023 and the cold water switch 1033 according to the actual flow rate. Specifically, the controller may first determine a difference between the actual flow rate and the target flow rate, then determine a variation value of the hot water switch 1023 and a variation value of the cold water switch 1033 corresponding to the difference, further adjust the opening degree of the hot water switch 1023 according to the variation value of the hot water switch 1023, and adjust the opening degree of the cold water switch 1033 according to the variation value of the cold water switch 1033.

Similarly, if the controller determines that the actual temperature of the water flow output by the water line 1052 differs from the target temperature, the controller may first determine the difference between the actual temperature and the target temperature. If the difference indicates that the actual temperature is lower than the target temperature, the controller may determine an increase value of the temperature of the hot water required to be provided by the hot water pipeline 102 at the current flow rate according to the difference, and then instruct the heating device 1022 to heat the water in the hot water storage tank 1021 according to the increase value, so that the temperature of the hot water provided by the hot water pipeline 102 to the water outlet unit 105 is increased, and further, the temperature of the water flow output by the water outlet pipe 1052 meets the target temperature under the condition that the flow rate is not changed; or determining a change value requiring a decrease in the cold water switch 1033 and an increase in the hot water switch 1023 according to the difference, adjusting the degree of opening and closing of the cold water switch 1033 according to the decrease in the change value of the cold water switch 1033, and adjusting the degree of opening and closing of the cold water switch 1033 according to the increase in the change value of the hot water switch 1023.

If the difference indicates that the actual temperature is higher than the target temperature, the controller can determine a change value that requires an increase in the cold water switch 1033 and a decrease in the hot water switch 1023 based on the difference, adjust the degree of opening and closing of the cold water switch 1033 based on the increase in the change value of the cold water switch 1033, and adjust the degree of opening and closing of the cold water switch 1033 based on the decrease in the change value of the hot water switch 1023.

In one embodiment, the water purifier 10 includes a communication module; the communication module is connected with the controller, is connected with the terminal in a wireless or wired mode, and is used for receiving indication information sent by the terminal, wherein the indication information comprises target water temperature or target flow.

Optionally, the user may input the target water temperature and the target flow rate through an APP installed on the terminal. Specifically, when a user needs to use purified water at a target flow rate and a target water temperature, the user can open a terminal APP and input the target water temperature and the target flow rate on an input interface of the APP. The terminal transmits request information including the target water temperature and the target flow rate input by the user to the water purifier 10 after determining that the user input is completed. After receiving the request information, the communication module of the water purifier 10 may feed back the request information to the controller. The controller can control the hot water switch 1023 and the cold water switch 1033 to make the temperature of the water flow output by the water outlet pipe 1052 meet the target water temperature; or the hot water switch 1023 and the cold water switch 1033 are controlled according to the target flow rate, so that the flow rate of the water flow output by the water outlet pipe 1052 is the same as the target flow rate.
