Description

Technical Field

[0002] An instant water heater is a device that quickly heats and supplies water to meet users' water needs. Most instant water heaters on the market store water in a room-temperature tank and use a pump to draw the water from the tank into a heating element. By controlling the heating power of the heating element and the water flow rate of the pump, the water temperature at the outlet reaches the user's set temperature.

[0003] In winter, the inlet water temperature is relatively low, generally around 5℃. During peak electricity usage periods, the mains voltage in users' homes may be lower. If the voltage is lower than the preset mains voltage, energy loss will cause the water purifier's outlet water temperature to be lower than the user's desired temperature, affecting the user's water experience.

[0004] In existing technologies, the water purifier's outlet water temperature is adjusted to meet user needs by increasing the power of the heating element or reducing the water flow rate. However, this increases costs and negatively impacts the user's experience with the water flow rate.

[0067] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0068] With the increasing demand for hot water, instant hot water purifiers have become widely popular. These purifiers typically store water in a room-temperature tank (to check for water shortage and prevent the risk of dry burning). A pump draws water from the tank into the heating element. By controlling the heating power of the heating element and the water flow rate of the pump, the water temperature at the outlet reaches the user's set temperature. The heating element is generally rated at 2100W. To prevent the risk of high-temperature water vaporization and ejection, the minimum water flow rate controlled by the pump is limited, typically set at 300ml / min.

[0069] In winter, the inlet water temperature is generally around 5℃. During peak electricity usage periods, the mains voltage at users' homes is lower. If the voltage is below 200V, according to the heat energy conversion formula: Q = CmΔt, the converted Δt = Pt / Cm, where Δt = outlet water temperature - inlet water temperature, C is the specific heat of water, P is the heating power, and m / t can be converted into instantaneous water flow rate. To ensure that 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, but due to the mains voltage of only 200V, the actual heating element power is only 1736W) and reduce the water flow rate (minimum 300ml / min). The calculated Δt = 83℃. Due to energy loss in the heating element, assuming a heating element thermal efficiency of 95%, Δt = 83℃ * 95% = 79℃. Therefore, when the inlet water temperature is 5℃, the maximum outlet water temperature is 5 + 79 = 84℃. During peak electricity consumption periods in winter, even with the heating element at maximum power and the water flow rate at minimum, the outlet temperature is only 84℃, which cannot meet the user's maximum outlet temperature setting of 95℃.

[0070] This application provides a heating method for a water purifier. To improve the efficiency of hot water output and meet user temperature requirements, the inlet water is preheated to ensure that the output water reaches the user-set temperature in winter, thus improving the efficiency of hot water output and enhancing the user experience. (See also...) Figure 1 The heating method of the water purifier includes steps S101 to S109.

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

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

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

[0074] The voltage is detected using the voltage detection device to obtain the current voltage information;

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

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

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

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

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

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

[0081] In one possible implementation, such as Figure 2 As shown, the water purifier also includes a water purification module and an ultraviolet sterilizer. The water purification module purifies the incoming water, and the purified water is then input into the ultraviolet sterilizer for sterilization, resulting in sterilized water. The sterilized water can be input into a water tank or directly output through the water outlet of the water purifier.

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

[0083] In this implementation, the voltage detection device is used to detect the voltage to obtain the current voltage information, and the temperature detection device is used to detect the temperature of the water entering the water inlet pipe to obtain the current inlet water temperature information. This facilitates subsequent temperature prediction based on the current voltage information and the current inlet water temperature information, improving the convenience of control and thus improving the efficiency of water purifier control.

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

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

[0086] The step of predicting the outlet water temperature based on the current voltage information and the current inlet water temperature information includes:

[0087] Obtain the preset heating power of the heating device and the preset water flow rate of the pumping device;

[0088] Based on the principle of heat energy conversion, the predicted outlet water temperature is calculated using the current voltage information, the current inlet water temperature information, the preset heating power, and the preset water flow rate.

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

[0090] In one 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 one possible implementation, the preset water flow rate of the pumping device is the minimum water flow rate set by 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 predicted outlet water temperature Tout can be calculated when the heating element is turned on to its maximum power and the water pump adjusts the water flow to its minimum under the current voltage and inlet water temperature.

[0093] In one possible implementation, the heat energy conversion formula is Q = CmΔt, and after conversion, Δt = Pt / Cm, where Δt = outlet water temperature - inlet water temperature, C is the specific heat of water, P is the heating power, and m / t can be converted into instantaneous water flow rate. Specifically, based on the preset heating power of the heating device and the current voltage information, the current power of the heating device is obtained. Taking the current power of the heating device as P and the preset water flow rate value of the pumping device as m / t, substituting these values ​​into Δt = Pt / Cm, the difference between the predicted outlet water temperature information and the current inlet water temperature information is obtained. Given the current inlet water temperature information, the predicted outlet water temperature information can be obtained.

[0094] In this implementation, based on the principle of heat energy conversion, the predicted outlet water temperature is calculated using the current voltage information, the current inlet water temperature information, the preset heating power, and the preset water flow rate. This allows for the determination of whether the outlet water temperature meets the user's needs, improving the accuracy of outlet water temperature prediction in the current usage scenario and thus enhancing the accuracy of subsequent determinations regarding whether preheating is required.

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

[0096] If the predicted outlet water temperature is less than a preset temperature threshold, it is determined that the predicted outlet water temperature meets the preset inlet water heating condition.

[0097] If the predicted outlet water temperature is greater than or equal to a preset temperature threshold, it is determined that the predicted outlet water temperature does not meet the preset inlet water heating conditions.

[0098] In one possible implementation, the preset temperature threshold is based on a user setting for the water purifier, or it can be based on the factory settings of the water purifier. Specifically, the preset temperature threshold can be 95°C.

[0099] In one possible implementation, if 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 rise condition.

[0100] In one possible implementation, if 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 reach 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 heating condition.

[0101] In this implementation, the determination of whether preheating is needed is improved by comparing the predicted water temperature information with the preset temperature threshold.

[0102] In step S105, if the predicted water temperature information meets the preset water inlet temperature rise conditions, the target water inlet temperature information is determined.

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

[0104] Based on the principle of heat energy conversion, the target inlet water temperature information is obtained by calculating based on the preset temperature threshold, the current voltage information, and the current inlet water temperature information, so that the water purifier can obtain an outlet water temperature that meets the preset outlet water temperature condition under the target inlet water temperature information.

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

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

[0107] In this implementation, the target inlet water temperature required under the current voltage information is determined based on the principle of heat energy conversion, so that the water purifier can obtain an outlet water temperature that meets the preset outlet water temperature conditions under the target inlet water temperature information, thereby improving the user experience.

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

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

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

[0111] If the target inlet water temperature is less than or equal to the safe temperature threshold, the heating control information is determined to be: heating the water entering the water purifier to the target inlet water temperature based on the heating device, and inputting the water heated to the target inlet water temperature into the water tank based on the circulation device.

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

[0113] In one possible implementation, since the water tank and circulation piping are not tolerant of excessively high temperatures, the target inlet water temperature must be less than or equal to a safe temperature threshold. Specifically, the safe temperature threshold is 25°C.

[0114] In one possible implementation, if the target inlet water temperature is less than or equal to the safe temperature threshold, the water entering the water purifier is heated to the target inlet water temperature using a heating device, and the heated water is then fed into the water tank using a circulation device.

[0115] In this implementation, the water entering the water purifier is heated to the target inlet water temperature using a heating device, and the heated water is then fed into the water tank using a circulation device. This method is simple to operate and easy to implement, does not require changing the water purifier's operating power, reduces costs, and simultaneously outputs hot water that meets user needs, thus improving the 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 one possible implementation, after controlling the water purifier based on the heating control information, the method further includes:

[0118] Obtain the hot water output command of the object, wherein the hot water output command includes the target outlet water temperature information;

[0119] The heating device is controlled to heat water so that the current outlet water temperature of the water purifier matches the target outlet water temperature information.

[0120] If the current outlet water temperature of the water purifier 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.

[0121] In one possible implementation, when a user needs hot water, the water purifier is operated to generate a hot water output command, which includes the target temperature information of the water to be used at that time.

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

[0123] In one possible implementation, the temperature of the water outlet from the heating device is detected by the temperature detection device to obtain the current water outlet temperature of the water purifier.

[0124] In one possible implementation, if 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 one possible implementation, if 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 to ensure that the current outlet water temperature meets the preset outlet water temperature conditions, thus avoiding the problem of low outlet water temperature during peak electricity consumption periods in winter and meeting the user's water needs.

[0127] The above embodiments of this application have the following beneficial effects: The embodiments of this application acquire current voltage information and current inlet water temperature information; perform temperature prediction based on the current voltage information and the current inlet water temperature information to obtain predicted outlet water temperature information; determine target inlet water temperature information when the predicted outlet water temperature information meets preset inlet water heating conditions; determine the heating control information of the water purifier based on the target inlet water temperature information; and control the water purifier based on the heating control information to ensure that the current outlet water temperature of the water purifier meets the preset outlet water temperature conditions.
