[0023] The technical solution in the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0024] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0025] Figure 1 1 is a schematic diagram of a water treatment device provided in an embodiment of the present application. In the present application, the water treatment device includes an external water source 1, a solenoid valve 2, a water pump 3, a flow sensor 4, a water volume sensor 5, a heating device 6, a water outlet 7, and a control component.

[0026] The solenoid valve 2 is usually composed of an electromagnet, a valve body, a valve core, a seal, and other parts. The electromagnet is a device that generates a magnetic field, the valve body is the part of the pipe through which water flows, and the valve core is a moving part controlled by the electromagnet to open or close the water flow channel. The control component adjusts the opening degree of the solenoid valve 2 by changing the width of the pulse signal, thereby achieving more precise water flow control.

[0027] The water pump 3 generates negative pressure at the water inlet end through its internal mechanical structure, thereby pumping water from a low place to a high place and delivering it to the water supply pipe of the water treatment equipment. In addition, the water pump 3 is adjustable, and the control component can adjust the output flow of the water pump accordingly by applying a voltage to the motor of the water pump to meet different water needs and achieve precise control of the target flow.

[0028] The flow sensor 4 is used to detect the flow of water in the water supply pipeline. The flow of water in the water supply pipeline can be obtained by different methods, including:

[0029] Differential pressure method: Calculate flow rate by measuring the pressure difference generated when the fluid flows in the water supply pipeline;

[0030] Electromagnetic method: Using Faraday's electromagnetic induction principle, the induced potential generated by water cutting magnetic lines of force is measured to calculate the flow rate of water in the water supply pipeline;

[0031] Ultrasonic method: Calculate the flow rate of water in the water supply pipeline by transmitting and receiving ultrasonic signals and measuring the time difference of water flow;

[0032] Vortex method: When water flows in the water supply pipe, a vortex will be formed behind the water supply pipe. The flow rate of water in the water supply pipe can be calculated by measuring the frequency of the vortex.

[0033] Thermal method: Calculate the flow rate of water in the water supply pipe by measuring the heat carried away by the water as it flows.

[0034] The water volume sensor 5 is used to detect the amount of water in the water supply pipeline. In the present application, the water volume sensor can be used to calculate the percentage of the water transported in the water supply pipeline to the volume of the water supply pipeline. It can be understood that the larger the percentage, the more water is transported in the water supply pipeline.

[0035] The heating device 6 is used to heat the water in the water supply pipe and output the water to the water treatment equipment through the water outlet 7 for users to drink.

[0036] The water treatment equipment may also include a control component, which is arranged in the accommodating cavity and is used to process related calculations and control logic in the water treatment equipment. For example, the water treatment equipment may also include physical control buttons, touch screens, etc. The start-up, temperature adjustment and other control logics of the water treatment equipment can be controlled by physical control buttons or virtual buttons on the touch screen.

[0037] The water treatment equipment may also include a network module, which may be used to provide wireless network services or wired network services, such as wireless networks such as wireless local area networks (WLAN), local area networks (LAN), cellular networks, 2G networks, 3G networks, 4G networks, 5G networks, etc. When the network module is connected to the network, users can control the opening, closing, or temperature adjustment of the water treatment equipment through mobile phones, tablets, and other devices, thereby realizing remote control of the water treatment equipment.

[0038] It should be noted that Figure 1The structural schematic diagram of the water treatment equipment shown is only an example. The structural schematic diagram of the water treatment equipment described in the embodiment of the present application is to more clearly illustrate the technical solution of the embodiment of the present application, and does not constitute a limitation on the technical solution provided in the embodiment of the present application. Ordinary technicians in this field can know that with the evolution of water treatment equipment, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

[0039] like Figure 1 It can be seen from the structural schematic diagram that in the embodiment of the present application, the water source of the water treatment equipment is outside the water treatment equipment, that is, the water treatment equipment does not have a water tank to store drinking water. When the user needs to use the water treatment equipment to get hot water, he can input the water temperature and water volume, and then the water treatment equipment obtains water from its external water source, heats it to the water temperature set by the user, and then directly discharges water. It does not need to pre-heat the water or keep it warm for a long time, and can be heated when used. However, since it directly heats the water in the water supply pipe through the heating device, if there is no water or less water in the water supply pipe, the heating device will have the problem of dry burning.

[0040] Based on this, in an embodiment of the present application, the target sensor is determined by the operating status of the flow sensor and the water volume sensor installed in the water supply pipeline of the water treatment equipment, and then the heating power of the heating device is determined by the water outlet data collected by the target sensor. Since the target sensor is determined by the first operating status of the flow sensor and the second operating status of the water volume sensor, the target sensor can accurately obtain the water outlet data in the water supply pipeline. Therefore, the heating power determined based on the water outlet data can accurately control the operation of the heating device and avoid dry burning of the heating device.

[0041] based on Figure 1 The structure shown is shown below. Figure 2-Figure 6 , the anti-dry burning control method provided in the embodiment of the present application is introduced in detail.

[0042] See also Figure 2 , which is a flow chart of a method for preventing dry burning control according to an embodiment of the present application. Figure 2 As shown, the method of the embodiment of the present application may include the following steps S101-S103.

[0043] S101, obtaining a first operating state of a flow sensor and a second operating state of a water volume sensor;

[0044] In one embodiment, after receiving the water temperature and water volume input by the user through the touch screen of the water treatment device, the control component can control the solenoid valve and the water pump to transport the water in the water source outside the water treatment device to the water supply pipeline of the water treatment device. When it obtains the water output data in the water supply pipeline through the flow sensor and the water volume sensor, it first needs to determine the first operating state of the flow sensor and the first operating state of the water volume sensor.

[0045] Specifically, the first operating state of the flow sensor may include that the flow sensor is in a working state or that the flow sensor is in a faulty state; the second operating state of the water sensor may include that the water sensor is in a working state or that the water sensor is in a faulty state. It is understandable that when the flow sensor is in a working state, it can normally obtain the water flow rate in the water supply pipeline, and when the flow sensor is in a faulty state, it cannot accurately obtain the water flow rate in the water supply pipeline, that is, the flow sensor can accurately detect the water flow rate in the water supply pipeline when it is in normal operation. Similarly, when the water sensor is in a working state, it can obtain the total amount of water output in the water supply pipeline, and when the water sensor is in a faulty state, it cannot obtain the correct data of the total amount of water output in the water supply pipeline. The total amount of water output collected by the control component through the water sensor can be expressed by a ratio, which represents the ratio of the amount of water in the water supply pipeline to the capacity of the water supply pipeline, such as 20%, 70%, etc. The water flow rate collected by the flow sensor can be expressed in milliliters per minute, which represents the water output per minute, such as 40mL / min, 100mL / min.

[0046] In an embodiment of the present application, the control component can control the change of the working parameters of the water pump or the solenoid valve. If the water flow rate detected by the flow sensor and the total water output detected by the water volume sensor also change accordingly, it is determined that the flow sensor is in a working state, otherwise it is determined to be in a fault state.

[0047] S102, determining a target sensor among a water volume sensor and a flow rate sensor based on the first operating state and the second operating state;

[0048] In one embodiment, after the first operating state of the flow sensor and the second operating state of the water volume sensor, the target sensor is determined through the first operating state and the second operating state.

[0049] It can be understood that the target sensor may include any one or both of a flow sensor and a water volume sensor.

[0050] Specifically, in the embodiment of the present application, the sensor that determines the working status of the running status is the target sensor.

[0051] S103, determining the heating power of the heating device based on the water output data collected by the target sensor, and controlling the heating device to heat according to the heating power.

[0052] In one embodiment, when determining the target sensor, water output data obtained by the target sensor is obtained, and the heating power of the heating device is determined based on the water output data. The water output data is relevant data of water in the water supply pipe, which includes water flow rate and total water output.

[0053] Optionally, in an embodiment of the present application, the heating power corresponding to the water output data can be pre-stored, so that when the real-time water output data is acquired through the target sensor, the corresponding heating power can be directly obtained, and the heating device can be controlled to perform heating based on the heating power.

[0054] In an embodiment of the present application, the target sensor is determined by the operating status of the flow sensor and the water volume sensor installed in the water supply pipeline of the water treatment equipment, and the heating power of the heating device is determined by the water outlet data collected by the target sensor. Since the target sensor is determined by the first operating status of the flow sensor and the second operating status of the water volume sensor, the target sensor can accurately obtain the water outlet data in the water supply pipeline. Therefore, the heating power determined based on the water outlet data can accurately control the operation of the heating device and avoid dry burning of the heating device.

[0055] See also Figure 3 , which is a flow chart of a method for preventing dry burning control according to an embodiment of the present application. Figure 3 As shown, the method of the embodiment of the present application may include the following steps S201-S205.

[0056] S201, obtaining a first operating state of a flow sensor and a second operating state of a water volume sensor;

[0057] For details, please refer to the description of step S101 in the above embodiment of the specification, which will not be elaborated here.

[0058] S202, if the first operating state is that the flow sensor is in a working state, and the second operating state is that the water volume sensor is in a fault state, determining that the flow sensor is a target sensor;

[0059] S203, if the first operating state is that the flow sensor is in a fault state, and the second operating state is that the water volume sensor is in a working state, determining that the water volume sensor is a target sensor;

[0060] S204, if the first operating state is that the flow sensor is in a working state, and the second operating state is that the water volume sensor is in a working state, determining that the flow sensor and the water volume sensor are target sensors;

[0061] S205, determining the heating power of the heating device based on the water output data collected by the target sensor, and controlling the heating device to heat according to the heating power.

[0062] Specifically, in the embodiment of the present application, when it is determined that the first operating state of the flow sensor is the working state, it means that the flow sensor is operating normally, and it can accurately collect the water flow rate in the water supply pipeline, that is, the water flow rate collected by the control component is accurate, and it can judge the size of the water flow in the water supply pipeline based on the water flow rate, and then the heating device can be accurately controlled based on the heating power determined by it; if it is determined that the first operating state of the flow sensor is a fault state, it means that the flow sensor cannot operate normally, and the water flow rate collected by it in the water supply pipeline is inaccurate. For example, when there is no water in the water supply pipeline, but the water flow rate collected by the control component through the flow sensor is 200mL / min, if the controller determines the heating power of the heating device according to the collected water flow rate, it will undoubtedly cause the heating power to dry burn. Therefore, when the operating state of the flow sensor is a fault state, the control component cannot use the water flow rate collected by the flow sensor to determine the heating power of the heating device, that is, determine that the target sensor is the flow sensor, and obtain the water flow rate of the water supply pipeline through it; similarly, when it is determined that the second operating state of the water volume sensor is the working state, the control component can use the total water output collected by the water volume sensor, that is, determine that the target sensor is the water volume sensor.

[0063] Optionally, in an embodiment of the present application, if it is determined that the first operating state of the flow sensor is a fault state and the second operating state of the water volume sensor is a fault state, it is determined that the water flow rate collected by the current flow sensor and the total water output collected by the water volume sensor are both unreliable, that is, there is no target sensor, and it is impossible to determine whether there is water in the water supply pipe. In order to avoid dry burning of the heating device and damage to the water treatment equipment, the heating device is directly turned off.

[0064] Furthermore, in an embodiment of the present application, the water treatment equipment also includes a temperature sensor installed at the water outlet of the water supply pipe. After determining that the flow sensor is the target sensor, if it is determined that the water flow rate of the water supply pipe obtained by the flow sensor is greater than or equal to a pre-set first flow threshold, the controller is still unable to determine whether the heating component has dry burning, and it is necessary to determine the heating power of the heating device through the water outlet temperature collected by the temperature sensor installed at the water outlet; if it is determined that the water flow rate is less than the first flow threshold, it is determined that the heating device has dry burning, and the heating power of the heating device is determined to be the first heating power. In the embodiment of the present application, the first heating power is zero, that is, the heating device is controlled to be turned off. Specifically, when determining the heating power of the heating device according to the outlet water temperature, if the control component obtains that the outlet water temperature is greater than or equal to the temperature threshold, it is determined that the heating device is currently dry-burning due to the high outlet water temperature, and the heating power of the heating device is determined to be the second heating power, where the second heating power is zero; if the outlet water temperature is less than the temperature threshold, it is determined that there is water in the heating device, and the heating power of the heating device is determined to be the third heating power, and the operation of the heating device is controlled according to the third heating power. The third heating power may be the power corresponding to the water temperature set by the user. When there is sufficient water in the water supply pipeline and there is no dry-burning in the heating device, the outlet water temperature of the water treatment equipment is controlled to be consistent with the set water temperature to meet the user's drinking needs, wherein the temperature threshold may be specifically 100°C, and the first flow threshold may be specifically 200mL / min.

[0065] It can be understood that the temperature threshold is the highest temperature of the water in the water treatment equipment. If the outlet water temperature is greater than the temperature threshold, it means that the heating device is currently dry-burning, causing the outlet water temperature detected at the outlet to be higher than the temperature threshold.

[0066] In an embodiment of the present application, the target sensor is determined by the operating status of the flow sensor and the water volume sensor, so that accurate water outlet data in the water supply pipeline can be obtained, thereby improving the accuracy of subsequent determination of the heating power of the heating device based on the water outlet data; and when the flow sensor is the target sensor, the heating power of the heating device is determined based on the water outlet temperature of the water outlet when the water flow rate in the water supply pipeline obtained by the flow sensor is greater than the first flow threshold, and when the water flow rate is less than the first flow threshold, the heating power of the heating device is determined to be the first heating power. In the case of a large water flow rate, it is further determined whether the heating device has dry burning based on the water outlet temperature, and then the heating power of the heating device is determined. The heating power of the heating device is determined by the water outlet temperature, which improves the accuracy of determining the heating power; and when it is determined that the water flow rate is less than the first flow threshold, the heating power of the heating device is directly determined to be the first heating power, so that the heating power of the heating component can be quickly determined.

[0067] See also Figure 4, which is a flow chart of a method for preventing dry burning control according to an embodiment of the present application. Figure 4 As shown, the water volume sensor is a target sensor, and the method of the embodiment of the present application may include the following steps S301-S305.

[0068] S301, obtaining a first operating state of a flow sensor and a second operating state of a water volume sensor;

[0069] S302, determining a target sensor among a water volume sensor and a flow rate sensor based on the first operating state and the second operating state;

[0070] For details, please refer to the description of step S101 in the above embodiment of the specification, which will not be elaborated here.

[0071] S303, if the total amount of water outflow from the water supply pipeline collected by the water volume sensor is greater than or equal to the first ratio threshold, determining that the heating power of the heating device is a fourth heating power;

[0072] S304, if the total amount of water outflow from the water supply pipeline collected by the water volume sensor is less than the first ratio threshold, determining that the heating power of the heating device is the fifth heating power, and the water outflow data includes the total amount of water outflow from the water supply pipeline;

[0073] S305, controlling the heating device to perform heating according to the heating power.

[0074] In one embodiment, the first ratio threshold and the fourth heating power can be pre-stored in the water treatment equipment. When the total amount of water output in the water supply pipeline collected by the water volume sensor is greater than or equal to the first ratio threshold, the heating power of the heating device is determined to be the fourth heating power; if the total amount of water output is determined to be less than the first ratio threshold, it is determined that the heating device currently has a risk of dry burning. In order to avoid dry burning of the heating device, the heating power of the heating device is determined to be the fifth heating power. Specifically, the first ratio threshold can be 70%, the fourth heating power is 80% of the current power, and the fifth heating power is zero, that is, the heating device is turned off.

[0075] Furthermore, in the process of controlling the operation of the heating device according to the fourth heating power, the water outlet temperature collected by the temperature sensor is greater than the temperature threshold. The water outlet temperature is too high, which determines that the heating device is currently dry-burning. It is further determined that the heating power of the heating device is the sixth heating power. The sixth heating power and the fifth heating power are less than the fourth heating power. Optionally, the sixth heating power can be zero, that is, the heating device is turned off.

[0076] In an embodiment of the present application, when the water volume sensor is the target sensor, when the total water output collected by the water volume sensor is greater than or equal to the first proportional threshold, the heating power of the heating component is determined to be the fourth heating power, and when the total water output of the water supply pipe is less than the first proportional threshold, the heating power of the heating device is determined according to the total water output of the water supply pipe, so that the heating power of the heating component can be accurately determined; and after controlling the heating power of the heating component to be the fourth heating power, the water outlet temperature of the heating component is lowered in real time. If the water outlet temperature of the heating component is too high, the heating power of the heating component is reduced to avoid dry burning of the heating component.

[0077] See also Figure 5 , which is a flow chart of a method for preventing dry burning control according to an embodiment of the present application. Figure 5 As shown, the water volume sensor and the flow sensor are target sensors, and the method of the embodiment of the present application may include the following steps S401-S405.

[0078] S401, obtaining a first operating state of a flow sensor and a second operating state of a water volume sensor;

[0079] For details, please refer to the description of step S101 in the above embodiment of the specification, which will not be elaborated here.

[0080] S402, determining a target sensor among a water volume sensor and a flow rate sensor based on the first operating state and the second operating state;

[0081] S403, if the water flow rate of the water supply pipeline collected by the flow sensor is greater than or equal to the second flow threshold, and the total amount of water outflow from the water supply pipeline collected by the water volume sensor is greater than or equal to the second ratio threshold, then the outlet water temperature of the water outlet collected by the temperature sensor is obtained, and the heating power of the heating device is determined based on the outlet water temperature;

[0082] S404, if the water flow rate of the water supply pipeline collected by the flow sensor is less than the second flow threshold, or the total amount of water output of the water supply pipeline collected by the water volume sensor is less than the second ratio threshold, then determine that the heating power of the heating device is the seventh heating power;

[0083] S405, controlling the heating device to perform heating according to the heating power.

[0084] In one embodiment, when it is determined that the first operating state of the flow sensor and the second operating state of the water volume sensor are working states, the flow sensor and the water volume sensor are determined to be target sensors, and when the water flow rate of the water supply pipeline collected by the flow sensor is greater than or equal to the second flow threshold, and the total water outlet of the water supply pipeline collected by the water volume sensor is greater than or equal to the second proportional threshold, it is determined that there is water in the water supply pipeline, and the outlet water temperature of the water outlet collected by the temperature sensor is further obtained. When the outlet water temperature of the water outlet is greater than or equal to the temperature threshold, it is determined that dry burning currently occurs in the heating device, thereby determining that the heating power of the heating device is The eighth heating power, the eighth heating power can be zero, that is, when it is determined that the water outlet temperature of the water outlet is greater than the temperature threshold, it is determined that the heating device is dry-burned. In order to avoid the heating device from continuing to dry-burn, the heating device needs to be turned off; if the water outlet temperature of the water outlet collected by the temperature sensor is less than the temperature threshold, the water temperature set by the user is compared with the water outlet temperature. If the water outlet temperature is greater than the set water temperature, it is determined to reduce the heating power of the heating device; if the water outlet temperature is less than the water temperature set by the user, the heating power of the heating device is increased; if the water outlet temperature is equal to the water temperature set by the user, the heating power of the heating device is maintained. In another case in the embodiment of the present application, if it is determined that the water flow rate of the water supply pipeline collected by the flow sensor is less than the second flow threshold, or the total amount of water outlet of the water supply pipeline collected by the water volume sensor is less than the second ratio threshold, it is determined that there is insufficient water in the water supply pipeline. In order to avoid the dry burning of the heating device, the heating power of the heating device is determined to be the seventh heating power, wherein the seventh heating power can be zero, the second flow threshold can be 100mL / min, the second ratio threshold can be 70%, and the temperature threshold is 100℃.

[0085] In an embodiment of the present application, when the water volume sensor and the flow sensor are determined as the target sensors, the heating power of the heating device is determined by the water flow rate of the water supply pipeline collected by the flow sensor and the total water output of the water supply pipeline collected by the water volume sensor, and the water output data in the water supply pipeline is accurately obtained, thereby controlling the heating power of the heating device, which can avoid dry burning of the heating device; and when the outlet water temperature is greater than the temperature threshold, the heating device is controlled to be turned off, and when the outlet water temperature is less than the temperature threshold, the heating power of the heating device is adjusted based on the outlet water temperature, so that the outlet water temperature can meet the user's drinking needs and improve the user's satisfaction with the water treatment equipment.

[0086] The following will be combined Figure 6 The anti-dry burning control method provided in the embodiment of the present application is described in detail with reference to a specific example.

[0087] In an embodiment of the present application, a first operating state of the flow sensor and a second operating state of the water volume sensor are obtained. If the flow sensor is in a normal working state and the water volume sensor is in a normal working state, it is further determined whether the water flow rate is greater than or equal to 100 mL / min and whether the total water output is greater than or equal to 70%. If so, the water outlet temperature is obtained.
