[0002] An instant water heater is a device that quickly heats water to meet user needs. Instant water purifiers on the market typically store water in a normal-temperature tank. A pump pumps the water into a heating pipe. By controlling the heating pipe's heating power and the pump's flow rate, the water at the outlet reaches the user's desired temperature.

[0003] In winter, the inlet water temperature is relatively low, generally around 5°C. During peak hours, the mains voltage at the user's home will be low.

[0067] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0068] With increasing water demand, instant water purifiers are becoming increasingly popular. These commercially available purifiers typically store water in a normal-temperature tank (to detect water shortages and prevent the risk of dry-burning). A pump pumps the water into the heating tube. By controlling the heating power and flow rate of the pump, the outlet temperature reaches the user-set setting. The rated power of the heating tube is typically 2100W. To prevent the risk of high-temperature water vaporization and jetting, the pump controls the minimum water flow rate, typically set at 300ml / min.

[0069] In winter, the inlet water temperature is relatively low, generally around 5°C. During peak hours, the mains voltage in a user's home can be low. If the voltage is below 200V, the thermal energy conversion formula is: Q = CmΔt. After conversion, Δt = Pt / Cm, where Δt = outlet water temperature - inlet water temperature, C is the specific heat of water, and P is the heating power. m / t can be converted into instantaneous water flow. To ensure the outlet water temperature equals the user-set outlet water temperature under current conditions, the control strategy is to increase the heating element power (maximum 2100W; due to the 200V mains voltage, the actual heating element power is only 1736W) and reduce the water flow rate (minimum 300ml / min). The calculated result is: Δt = 83°C. Due to energy losses in the heating element, assuming a 95% thermal efficiency, Δt = 83°C * 95% = 79°C. Therefore, when the inlet water temperature is 5°C, the maximum outlet water temperature is 5 + 79 = 84°C. During the peak electricity consumption period in winter, even if the heating tube is at maximum power and the water flow is minimum, the water outlet temperature is only 84°C, which cannot meet the user's set maximum water outlet temperature of 95°C.

[0070] The embodiment of the present application provides a heating method for a water purifier. In order to improve the efficiency of hot water output and meet the user's requirements for water temperature, the incoming water is preheated to ensure that the water output reaches the user-set temperature in winter, thereby improving the efficiency of the water purifier in hot water output and enhancing the user experience. Figure 1 The heating method of the water purifier includes steps S101 to S109.

[0071] In step S101, current voltage information and current inlet water temperature information are obtained.

[0072] In a possible implementation, the water purifier includes a voltage detection device and a temperature detection device, and the temperature detection device is arranged at a preset detection position of the water inlet pipe of the water purifier.

[0073] The obtaining of current voltage information and current inlet water temperature information includes:

[0074] Performing voltage detection based on the voltage detection device to obtain the current voltage information;

[0075] The temperature of the inlet water of the water inlet pipe is detected based on the temperature detection device to obtain the current inlet water temperature information.

[0076] In one possible implementation, Figure 2 As shown, the water purifier includes a voltage detection device and a temperature detection device, and the temperature detection device is arranged at a preset detection position of the water inlet pipe of the water purifier.

[0077] In a possible implementation, the voltage detection device is electrically connected to the mains power supply input terminal, and the voltage detection device is used to detect the voltage of the mains power supply input signal of the water purifier.

[0078] In a possible implementation, the current voltage information is the mains voltage at the location of the water purifier.

[0079] In a possible implementation, the current voltage information is obtained by detecting the mains voltage of the user's home in real time through a voltage detection circuit.

[0080] In a possible implementation, the current inlet water temperature information is obtained by detecting the temperature of the inlet water of the water inlet pipe by the temperature detection device.

[0081] In one possible implementation, Figure 2 As shown, the water purifier also includes a water purification module and a UV sterilizer. The water purification module purifies incoming water, which is then sterilized in the UV sterilizer to produce sterilized water. The sterilized water can be fed into a water tank or directly discharged through the water outlet of the water purifier.

[0082] In one possible implementation, Figure 2 As shown, the water purifier further includes a three-way valve, which is used to control the communication between the circulation device and the water tank, and to control the communication between the heating device and the circulation device.

[0083] In this implementation, the current voltage information is obtained by performing voltage detection on the voltage detection device, and the current inlet water temperature information is obtained by performing temperature detection on the inlet water of the water inlet pipe based on the temperature detection device. This facilitates subsequent temperature prediction based on the current voltage information and the current inlet water temperature information, improves the convenience of control, and thereby improves the efficiency of controlling the water purifier.

[0084] In step S103, temperature prediction is performed based on the current voltage information and the current inlet water temperature information to obtain predicted outlet water temperature information.

[0085] In a possible implementation, the water purifier includes a heating device, a pumping device, and a water tank. The pumping device is used to input water in the water tank into the heating device.

[0086] The predicting based on the current voltage information and the current inlet water temperature information to obtain the predicted outlet water temperature information includes:

[0087] Obtaining a preset heating power of the heating device and a preset water flow value of the pumping device;

[0088] According to the principle of heat energy conversion, the predicted water outlet temperature information is obtained by calculation based on the current voltage information, the current water inlet temperature information, the preset heating power and the preset water flow value.

[0089] In one possible implementation, Figure 2 As shown, the water purifier includes a heating device, a pumping device and a water tank, and the pumping device is used to input water in the water tank into the heating device.

[0090] In a possible implementation, the preset heating power of the heating device is the rated power of the heating device. Specifically, the heating device is a heating tube.

[0091] In a possible implementation, the preset water flow rate value of the pumping device is a set minimum water flow rate of the pumping device. Specifically, the pumping device is a water pump.

[0092] In one possible implementation, based on the principle of thermal energy conversion, the outlet water temperature Tout can be calculated under the current voltage and inlet water temperature when the heating pipe is turned to maximum power and the water pump adjusts the water flow to the minimum, that is, the predicted outlet water temperature information.

[0093] In one possible implementation, the thermal energy conversion formula is Q = CmΔt. After conversion, Δt = Pt / Cm, where Δt = outlet water temperature - inlet water temperature, C is the specific heat of water, and P is the heating power. m / t can be converted into instantaneous water flow. Specifically, the current power of the heating device is obtained based on the preset heating power of the heating device and the current voltage information. The current power of the heating device is used as P, and the preset water flow value of the pumping device is used as m / t. Δt = Pt / Cm is substituted into the equation to obtain the difference between the predicted outlet water temperature information and the current inlet water temperature information. Given the current inlet water temperature information, the predicted outlet water temperature information can be obtained.

[0094] In this implementation, according to the principle of thermal energy conversion, the predicted water outlet temperature information is obtained by calculation based on the current voltage information, the current water inlet temperature information, the preset heating power and the preset water flow value. The predicted value of the water outlet temperature under the current voltage information can be obtained, which is convenient for judging whether the water outlet temperature under the current voltage information meets user needs, improves the accuracy of the prediction of the water outlet temperature under the current usage scenario, and further improves the accuracy of the subsequent judgment of whether preheating is required.

[0095] In a possible implementation, the method further includes:

[0096] When the predicted outlet water temperature information is less than a preset temperature threshold, determining that the predicted outlet water temperature information meets the preset inlet water temperature increase condition;

[0097] When the predicted outlet water temperature information is greater than or equal to the preset temperature threshold, it is determined that the predicted outlet water temperature information does not meet the preset inlet water temperature increase condition.

[0098] In a possible implementation, the preset temperature threshold is set by the user for the water purifier, and the preset temperature threshold may also be set based on factory parameters of the water purifier. Specifically, the preset temperature threshold may be 95°C.

[0099] In one possible implementation, when the predicted outlet water temperature information is less than the preset temperature threshold, it is determined that the predicted outlet water temperature information does not meet the outlet water temperature condition and preheating is required, that is, the predicted outlet water temperature information meets the preset inlet water temperature rising condition.

[0100] In one possible implementation, when the predicted outlet water temperature information is greater than or equal to the preset temperature threshold, it is determined that the predicted outlet water temperature information can meet the outlet water temperature condition and no preheating is required, that is, the predicted outlet water temperature information does not meet the preset inlet water temperature rising condition.

[0101] In this implementation, whether preheating is required is determined by comparing the predicted outlet water temperature information with the preset temperature threshold, thereby improving the efficiency of the determination.

[0102] In step S105, when the predicted outlet water temperature information satisfies the preset inlet water temperature increase condition, the target inlet water temperature information is determined.

[0103] In a possible implementation, determining target inlet water temperature information includes:

[0104] According to the principle of thermal energy conversion, calculation is performed based on the preset temperature threshold, the current voltage information and the current water inlet temperature information to obtain the target water inlet temperature information, so that the outlet water temperature obtained by the water purifier under the condition of the target water inlet temperature information meets the preset water outlet temperature condition.

[0105] In one possible implementation, Figure 2 As shown, the water purifier includes a current water inlet temperature detection device, which is arranged near the water inlet of the heating device. The current water inlet temperature detection device is a temperature sensor, which is used to detect the water inlet temperature of the heating device and obtain the current water inlet temperature information.

[0106] In one possible implementation, the thermal energy conversion formula is Q = CmΔt. After conversion, Δt = Pt / Cm, where Δt = outlet water temperature - inlet water temperature, C is the specific heat of water, and P is the heating power. m / t can be converted into instantaneous water flow. Specifically, the output power of the heating device at the current voltage is calculated as P, the minimum water flow rate of the water pump is m / t, and when the outlet water temperature reaches the preset temperature threshold, the inlet water temperature is calculated as the target inlet water temperature information.

[0107] In this implementation, the target water inlet temperature information required under the current voltage information is determined according to the principle of thermal energy conversion, so that the outlet water temperature obtained by the water purifier under the target water inlet temperature information meets the preset outlet water temperature condition, thereby improving the user experience.

[0108] In step S107, heating control information of the water purifier is determined according to the target water inlet temperature information.

[0109] In a possible implementation, the water purifier further includes a circulation device, which is connected to the heating device and the water tank respectively.

[0110] The step of determining the heating control information of the water purifier according to the target water inlet temperature information includes:

[0111] When the target water inlet temperature information is less than or equal to the safety temperature threshold, the heating control information is determined as follows: the water inlet of the water purifier is heated to the target water inlet temperature information based on the heating device, and the water inlet heated to the target water inlet temperature information is input into the water tank based on the circulation device.

[0112] In one possible implementation, Figure 2 As shown, the water purifier includes a circulation device, which is connected to the heating device and the water tank respectively. Specifically, the circulation device can be a circulation pipeline.

[0113] In one possible implementation, since the water tank and the circulation pipeline cannot tolerate excessively high temperatures, the target water inlet temperature information needs to be less than or equal to a safety temperature threshold, specifically, 25°C.

[0114] In one possible implementation, when the target inlet water temperature information is less than or equal to the safety temperature threshold, the inlet water of the water purifier is heated to the target inlet water temperature information based on the heating device, and the inlet water heated to the target inlet water temperature information is input into the water tank based on the circulation device.

[0115] In this implementation, the inlet water of the water purifier is heated to the target inlet water temperature information based on the heating device, and the inlet water heated to the target inlet water temperature information is input into the water tank based on the circulation device. The operation is simple and easy to implement. There is no need to change the working power of the water purifier, which reduces costs. At the same time, hot water that meets user needs is output, thereby improving user experience.

[0116] In step S109, the water purifier is controlled based on the heating control information so that the current outlet water temperature of the water purifier meets the preset outlet water temperature condition.

[0117] In a possible implementation, after controlling the water purifier based on the heating control information, the method further includes:

[0118] Obtaining a hot water output instruction of an object, wherein the hot water output instruction includes water outlet target temperature information;

[0119] Controlling the heating device to perform heating so that the current outlet water temperature of the water purifier matches the outlet water target temperature information;

[0120] In a case where the current outlet water temperature of the water purifier matches the outlet water target temperature information, it is determined that the current outlet water temperature of the water purifier meets the preset outlet water temperature condition.

[0121] In a possible implementation, when a user needs to use hot water, the user operates the water purifier to generate the hot water output instruction, and the hot water output instruction includes the target water temperature information for the current use.

[0122] In a possible implementation, the heating device is controlled to perform heating so that the current outlet water temperature of the water purifier matches the outlet water target temperature information.

[0123] In a possible implementation, the temperature of the outlet water of the heating device is detected based on the temperature detection device to obtain the current outlet water temperature of the water purifier.

[0124] In a possible implementation, when the current outlet water temperature matches the target outlet water temperature information, it is determined that the current outlet water temperature of the water purifier meets the preset outlet water temperature condition.

[0125] In a possible implementation, when the current outlet water temperature of the water purifier meets the preset outlet water temperature condition, hot water is output based on the water outlet switch of the water purifier.

[0126] In this implementation, the water purifier is controlled so that the current outlet water temperature of the water purifier meets the preset outlet water temperature condition, avoiding the problem of low outlet water temperature during the peak electricity consumption period in winter and meeting the water demand of users.

[0127] The above-mentioned embodiment of the present application has the following beneficial effects: the embodiment of the present application obtains current voltage information and current inlet water temperature information; performs temperature prediction based on the current voltage information and the current inlet water temperature information to obtain predicted outlet water temperature information; determines target inlet water temperature information when the predicted outlet water temperature information meets the preset inlet water heating condition; determines heating control information of the water purifier based on the target inlet water temperature information; and controls the water purifier based on the heating control information so that the current outlet water temperature of the water purifier meets the preset outlet water temperature condition.
