If not, the heating state is entered, the heating body is opened, and the detection value of the second temperature sensor reaches 95 DEG. The heating body is closed, the heat preservation state is entered, and the heat preservation state is exited when the temperature is lower than 92 DEG. The heating state is entered, so that the temperature of the water in the hot water storage device is ensured to be within 92 DEG to 95 DEG.

[0062] In a possible implementation, the water purifier further comprises an exhaust pipe, which is in communication with the hot water storage device and the water outlet respectively. The exhaust pipe is used to discharge the water vapor of the hot water storage device through the water outlet.

[0063] In this implementation, in the case that the user does not need to take water, the control information of the cold water storage device and the hot water storage device is determined respectively to replenish the water storage device, so that the water supply of the water purifier is ensured, and the user experience is improved.

[0064] In a possible implementation, the initial control information comprises first control information, second control information and third control information. The first control information represents control of water flowing from the mixing device into the hot water storage device. The second control information represents control of water flowing from the cold water storage device into the mixing device. The third control information represents control of water flowing from the hot water storage device into the mixing device. The determining of the initial control information based on the water use scenario information, the current water level information, and the current water temperature information further includes: When the water use scenario information is the second water use scenario, obtaining target water outlet temperature information; Calculating the temperature difference between the current water temperature information and the target outlet water temperature information; When the current water temperature information is greater than the target outlet water temperature information and the temperature difference is greater than a first preset difference, determining that the initial control information is the first control information; When the current water temperature information is greater than the target outlet water temperature information and the temperature difference is less than or equal to the first preset difference, determining that the initial control information is the second control information; When the current water temperature information is less than the target outlet water temperature information and the temperature difference is less than or equal to a second preset difference, determining that the initial control information is the first control information; When the current water temperature information is lower than the target outlet water temperature information and the temperature difference is higher than the second preset difference, the initial control information is determined to be the third control information.

[0065] In one possible implementation, when the water use scenario information is the second water use scenario, if the user currently takes room temperature water, the room temperature water pump directly supplies water at full load; if the user takes 95° hot water, the hot water pump directly supplies hot water at full load; if the user takes hot water at other temperatures, the system adjusts the duty cycle of the room temperature water pump and the hot water pump through PID regulation, and supplies water after the two are mixed.

[0066] In a possible implementation, when the current water temperature is greater than the target outlet water temperature and the temperature difference is greater than a first preset difference, the initial control information is determined to be the first control information. Specifically, the first preset difference is 5°C.

[0067] In one possible implementation, when the current water temperature is lower than the target outlet water temperature and the temperature difference is lower than or equal to a second preset difference, the initial control information is determined to be the first control information. Specifically, the second preset difference is -5°C.

[0068] In one possible implementation, Figure 3 As shown, when the user presses a button to perform a water extraction operation, the target outlet water temperature information T0 required by the user is obtained, the value T1 of the third temperature sensor at this time is read, and the size of T0 and T1 is determined.

[0069] In one possible implementation, Figure 3As shown, if T1 is greater than T0, and the difference between the two is greater than 5°C (the 5°C setting is system-related), it means that the stored water is overheated and the system cannot adjust it in time through the water mixing solution. In this case, the hot water return logic is triggered, and the stored water flows back to the hot tank, and then enters the water discharge logic.

[0070] In one possible implementation, Figure 3 As shown, if T1 is greater than T0 and the difference between the two is within 5°C, it means that the system can be adjusted in time through the water mixing solution and enter the water outlet logic.

[0071] In one possible implementation, Figure 3 As shown, if T1 is less than T0, and the difference between the two is greater than 5°C, and T1 is greater than 50°C, it means that the stored water is not hot enough, then the hot water return logic is triggered, the stored water flows back to the hot tank, and then enters the water discharge logic.

[0072] In one possible implementation, Figure 3 As shown, if T1 is less than T0, and the difference between the two is greater than 5°C, and T1 is less than 50°C, it means that the stored water is cold water, then the cold water return logic is triggered, and the stored water flows back to the normal temperature water tank, and then enters the water discharge logic.

[0073] In one possible implementation, Figure 3 As shown, if T1 is less than T0 and the difference between the two is within 5°C, it means that the system can be adjusted in time through the water mixing solution and enter the water outlet logic.

[0074] In one possible implementation, Figure 2 As shown, the water purifier further includes a reflux pump, which is connected to the water mixing device and the hot water storage device respectively, and the water stored in the water mixing device can flow back to the hot water storage device through the reflux pump.

[0075] In one possible implementation, Figure 4 As shown, the hot water return logic is as follows: turn on the return pump to pump the stored water back into the hot water storage device (the hot water storage device contains high-temperature water, which can ensure that the stored water quality is maintained after being heated); read the value T2 of the third temperature sensor at regular intervals; when the value T2 of the third temperature sensor = the value T3 of the first temperature sensor, or the value T2 of the third temperature sensor <T1-5°,TI为所述第二温度传感器的数值,此时存水已抽空,所以读到的值为空气温度,进入出水逻辑。

[0076] In one possible implementation, Figure 4 As shown, when the reflux time t>x seconds (this time limit is related to the reflux pump and the water storage volume, and is doubled on the basis of the normal reflux time), it will directly enter the water discharge logic after exiting.

[0077] In a possible implementation, as shown in Figure 2 The water purifier further includes a backflow valve, which is in communication with the water mixing device and the water purification module respectively, and the stored water of the water mixing device can flow back to the water purification module through the backflow valve and then flow into the cold water storage device after secondary purification. The water purification module further includes a one-way valve for guiding the water flow direction.

[0078] In a possible implementation, as shown in Figure 5 The hot water backflow logic is as follows: opening the backflow valve, the booster pump and the cold water inlet valve, and then the stored water is filtered again and flows into the cold water storage device (the length of time of storing water cannot be ensured, so the stored water is reused after being filtered again, which can ensure water quality and save water); the value T2 of the third temperature sensor is read every certain period; the value T2 of the third temperature sensor is equal to the value T3 of the first temperature sensor, or T2 < T1-5°, at this time, the stored water has been emptied, so the value read is the air temperature, and the water outlet logic is entered.

[0079] In a possible implementation, as shown in Figure 5 As shown in the figure, when the backflow time ∆t > x seconds (the time limit value is related to the backflow valve and the storage volume, and is one time longer than the normal backflow time), the water outlet logic is directly entered after exiting.

[0080] In a possible implementation, the water outlet logic is as follows: based on the value of the first temperature sensor and the value of the second temperature sensor, the duty ratio of the normal temperature water pump and the hot water pump is determined, the normal temperature water pump and the hot water pump are controlled, the water is mixed, and then the value of the third temperature sensor of the water mixing device is read in real time, the duty ratio of the normal temperature water pump and the hot water pump is fine-tuned according to the PID adjustment algorithm, so as to achieve the water temperature required by the user, that is, to match the target water outlet temperature information. Specifically, the PID (Proportional, Integral, Differential) control algorithm is a control algorithm that combines proportional, integral and differential three links, and the operation result is used to control the output according to the proportional, integral and differential function relationship of the input deviation value.

[0081] In this implementation, in a water use scenario in which the user does not need to take water, different control information is determined according to a plurality of detection information, so that the water outlet of the water purifier quickly meets the water use demand of the user, and the poor user experience of the initial water temperature not meeting the standard when the user takes water is avoided.

[0082] In step S107, the water purifier is controlled according to the initial control information, and an initial control result is obtained.

[0083] In a possible implementation, the controlling the water purifier according to the initial control information to obtain an initial control result comprises the following steps. In the case where the cold water level information is less than the preset cold water level information, opening a water inlet valve of the cold water storage device to supplement water to the cold water storage device to obtain supplemented cold water level information, In the case where the hot water level information is less than the preset hot water level information, opening a water inlet valve of the hot water storage device to supplement water to the hot water storage device to obtain supplemented hot water level information. Determining the supplemented cold water level information and the supplemented hot water level information as the initial control result.

[0084] In a possible implementation, in the case where the cold water level information is less than the preset cold water level information, that is, the cold water level information is lower than the position of the high liquid level float ball, water needs to be supplemented, a cold water water inlet valve of the cold water storage device is opened, and the cold water storage device is supplemented with water to obtain supplemented cold water level information.

[0085] In a possible implementation, in the case where the hot water level information is less than the preset hot water level information, that is, the hot water level information is lower than the position of the high liquid level probe, water needs to be supplemented, a hot water water inlet valve of the hot water storage device is opened, and the hot water storage device is supplemented with water to obtain supplemented hot water level information.

[0086] In this implementation, the water storage device is supplemented with water based on the water storage amount of the water storage device, the endurance of the water purifier is improved, and user experience is further improved.

[0087] In a possible implementation, the controlling the water purifier according to the initial control information to obtain an initial control result further comprises the following steps.

In the case where the initial control information is the second control information, controlling water of the cold water storage device to flow into the water mixing device to obtain current water mixing temperature information of the water mixing device, and determining the current water mixing temperature information as the initial control result. In the case where the initial control information is the third control information, controlling water of the hot water storage device to flow into the water mixing device to obtain current water mixing temperature information of the water mixing device, and determining the current water mixing temperature information as the initial control result.

[0088] In a possible implementation, in the case that the initial control information is the first control information, and it is indicated that the stored water is not hot enough, a hot water backflow logic is triggered to backflow the stored water into the hot tank, control the water of the water mixing device to flow into the hot water storage device, and then enter the water outlet logic.

[0089] In a possible implementation, after the hot water backflow, current hot water temperature information of the hot water storage device and current cold water temperature information of the cold water storage device are obtained, and it is determined that the current hot water temperature information and the current cold water temperature information are the initial control result.

[0090] In a possible implementation, in the case that the initial control information is the second control information, it is indicated that the water of the water mixing device is overheated, but the water of the target water outlet temperature information can be obtained through water mixing adjustment, the water of the cold water storage device is controlled to flow into the water mixing device, current water mixing temperature information of the water mixing device is obtained, and it is determined that the current water mixing temperature information is the initial control result.

[0091] In a possible implementation, in the case that the initial control information is the third control information, it is indicated that the water of the water mixing cavity is subcooled, but the water of the target water outlet temperature information can be obtained through water mixing adjustment, the water of the hot water storage device is controlled to flow into the water mixing device, current water mixing temperature information of the water mixing device is obtained, and it is determined that the current water mixing temperature information is the initial control result.

[0092] In this implementation, the water purifier is controlled according to different control logics, so as to facilitate the adjustment of water temperature that does not meet the standard in different cases, make the water outlet meet the user demand, and improve the precision of control.

The hot outlet water flow information of the hot water storage device and the cold outlet water flow information of the cold water storage device are determined as the correction control information.

[0096] In a possible implementation, in a case where the cold water level information after water replenishment is greater than or equal to the preset cold water level information, that is, the cold water level information is higher than or equal to the position of the high liquid level float ball, the correction control information is determined to be closing the water inlet valve of the cold water storage device.

[0099] In a possible implementation, in a case where the initial control information is the second control information or the third control information, the difference information between the current mixed water temperature information and the target outlet water temperature information is determined by identifying the water temperature of the mixed water device and the water temperature of the hot water storage device, and in a case where the difference information does not satisfy a preset outlet water condition, hot outlet water flow information of the hot water storage device and cold outlet water flow information of the cold water storage device are determined based on the difference information.

[0100] In the implementation, the corresponding correction processing scheme is determined according to the results obtained after control according to different water use scenarios, so as to facilitate correction control of the water purifier, improve the adaptability of the water purifier to various conditions, and improve the flexibility of control.

[0101] In step S1011, the water purifier is controlled according to the correction control information, so that the water purifier meets the preset use condition.
