The usual structure is to use an electric heater to heat the water in the kettle container until the water is boiled. Most electric water heaters use resistance heating tubes. In this state, it will burn out in a very short period of time. During the use of the electric water heater, due to the evaporation of water and the drop of the water level, it is easy to cause the liquid to dry out, the heater to burn out, and even a safety accident. Therefore, when the electric kettle is boiling water, the water level in the kettle should not be lower than the minimum water level, so as not to burn out the heat pipe. Regarding the electrical safety of liquid heaters, there are relevant provisions in national standards, including the labeling and control of high and low water levels. At present, in order to prevent temperature control failure or dry burning in the state of water shortage, most liquid heaters use bimetallic mechanical switches It is used as a protection to prevent the water level of the water boiler from being too low and easily causing dry heating. Some electric kettles use the principle of water conduction to judge the water level in the kettle, and use this as the basis for water level control, as disclosed on August 6, 2008. The Chinese utility model patent, the patent number is CN200720172731.X electric kettle water level detection device, which is equipped with a detection window in the electric kettle, and there are water level detection points inside. The electric circuit, thus causing the change of the resistance value, can judge the specific water level of the electric kettle according to the location of the detection point and the resistance value data. But there is following shortcoming in above prior art:
1） 双金属开关易于实现缺水状态下的防干烧功能，但难于控制水壶内的最低水位。 1) The bimetallic switch is easy to realize the anti-dry function in the state of water shortage, but it is difficult to control the minimum water level in the kettle.
2） 通过水位探测点的金属导体与水的阻值变化来判断水位高低的方法精确度不高，在工艺上存在极大难度，且电路结构相当复杂，成本偏高。 2) The method of judging the water level by the change of the resistance value between the metal conductor and the water at the water level detection point is not very accurate, and there are great difficulties in the process, and the circuit structure is quite complicated and the cost is high.

对于液体加热器类的电器产品，为保证产品电气安全，除了常规的温度控制电气设计、熔断器保护外，限制液体加热器的最低液位，可有效防止加热系统温度过高导致的温度灼伤、元件烧毁等事故。 For electrical products such as liquid heaters, in order to ensure the electrical safety of the products, in addition to the conventional temperature control electrical design and fuse protection, the minimum liquid level of the liquid heater is limited, which can effectively prevent temperature burns caused by excessive heating system temperature, Accidents such as component burnout.
本实用新型的液体加热器采用磁场感应涡流加热原理，在感应加热线圈交变磁场的作用下，金属筒内部形成涡流，迅速发热，将水加热。导管的末端位于电磁感应液体加热器的液位控制线上，即感温探头设置在液位控制线上，它与金属筒壁的距离A的范围是5≤A≤15mm，当非导体容器6（如玻璃杯）内的液体（如水）高于液位控制线时，水将浸过感温探头，感温探头所检测的温度是水体的温度，随着电磁感应液体加热器不断加热，玻璃杯内的水蒸发、水位下降，当水位低于液位控制线时，感温探头探出水面，金属筒部分环体裸露在空气中，而此时，金属筒继续发热，其热量使得附近的空气温度迅速升高，使感温探头所检测到的温度值随之上升，由于感温探头连接控制器的输入端，因此，控制器通过读取感温探头的输入信号，即可判断出玻璃杯内实时水位已经低于液位控制线了。控制器的输出端连接感应加热线圈的驱动电路，从而可断开感应加热线圈1的电源，使液体加热器停止加热。 The liquid heater of the utility model adopts the principle of magnetic field induction eddy current heating. Under the action of the alternating magnetic field of the induction heating coil, an eddy current is formed inside the metal cylinder to generate heat rapidly and heat the water. The end of the conduit is located on the liquid level control line of the electromagnetic induction liquid heater, that is, the temperature sensing probe is set on the liquid level control line, and the distance A between it and the metal cylinder wall is 5≤A≤15mm. When the non-conductive container is 6 When the liquid (such as water) in (such as a glass) is higher than the liquid level control line, the water will soak through the temperature sensing probe, and the temperature detected by the temperature sensing probe is the temperature of the water body. With the continuous heating of the electromagnetic induction liquid heater, the glass The water in the cup evaporates and the water level drops. When the water level is lower than the liquid level control line, the temperature sensor probes out of the water surface, and part of the ring body of the metal cylinder is exposed in the air. At this time, the metal cylinder continues to generate heat, and its heat makes the nearby The air temperature rises rapidly, so that the temperature value detected by the temperature sensor rises accordingly. Since the temperature sensor is connected to the input terminal of the controller, the controller can judge the temperature of the glass by reading the input signal of the temperature sensor. The real-time water level in the cup is lower than the liquid level control line. The output terminal of the controller is connected with the driving circuit of the induction heating coil, so that the power supply of the induction heating coil 1 can be cut off, so that the liquid heater stops heating.
本实用新型的电磁感应液体加热器的液位控制方法是这样的：在非导体容器内置有金属筒，在非导体容器外设置感应加热线圈，使金属筒置于感应加热线圈的交变磁场磁力线范围内，电气控制电路向感应加热线圈提供交变电流，在金属筒内侧的液位控制线附近设置感温探头，感温探头连接控制器，电磁感应液体加热器的液体加热温度设定值为Ta，预设差值Tb。当非导体容器内的液位高于液位控制线时，容器内的液体浸过感温探头，而感温探头检测的实时温度值T将约等于窗口内的液体温度，当液位下降至低于液位控制线时，感温探头暴露在空气中，而金属筒使附近的空气温度迅速升高，当感温探头检测的实时温度值T满足T≥Ta+Tb时，系统认为，容器内的液位已经低于警界线，从而断开感应加热线圈的供电。 The liquid level control method of the electromagnetic induction liquid heater of the utility model is as follows: a metal cylinder is built in the non-conductive container, an induction heating coil is arranged outside the non-conductive container, and the metal cylinder is placed on the alternating magnetic field line of the induction heating coil Within the range, the electrical control circuit provides alternating current to the induction heating coil, and a temperature-sensing probe is installed near the liquid level control line inside the metal cylinder. The temperature-sensing probe is connected to the controller, and the liquid heating temperature setting value of the electromagnetic induction liquid heater is Ta, the preset difference Tb. When the liquid level in the non-conductive container is higher than the liquid level control line, the liquid in the container is immersed in the temperature sensor, and the real-time temperature value T detected by the temperature sensor will be approximately equal to the temperature of the liquid in the window. When the liquid level drops to When it is lower than the liquid level control line, the temperature sensing probe is exposed to the air, and the metal cylinder makes the nearby air temperature rise rapidly. When the real-time temperature value T detected by the temperature sensing probe satisfies T≥Ta+Tb, the system considers that the container The liquid level inside has been lower than the alarm limit, thus disconnecting the power supply of the induction heating coil.
本实用新型的液位控制方法是为了防止液体加热器在低于最低液位时还继续工作，当容器内的液位低于设定的位置时，液体加热器将切断感应加热线圈的供电，并且，为了同时使加热温度控制同时停止工作，在电气控制电路的主回路上设置电源开关，当感温探头检测的实时温度值T满足T≥Ta+Tb时，断开电源开关。 The liquid level control method of the utility model is to prevent the liquid heater from continuing to work when the liquid level is lower than the minimum liquid level. When the liquid level in the container is lower than the set position, the liquid heater will cut off the power supply of the induction heating coil. Moreover, in order to stop the heating temperature control at the same time, a power switch is installed on the main circuit of the electrical control circuit. When the real-time temperature value T detected by the temperature sensor satisfies T≥Ta+Tb, the power switch is turned off.
上述的液体加热温度设定值Ta的范围是60—100℃。差值Tb的范围是5—25℃。优选：Ta的范围是80—100℃。差值Tb的范围是10—20℃。 The range of the above-mentioned liquid heating temperature setting value Ta is 60-100°C. The range of the difference Tb is 5-25°C. Preferably: the range of Ta is 80-100°C. The range of the difference Tb is 10-20°C.
在本实用新型中，金属筒上可以设置放电槽或放电孔，当感应加热线圈产生超音频电磁场，磁力线穿透硼硅高温玻璃壶等非导磁容器，对器皿内的水体进行高频切割，而置于非导磁容器内的环状金属，在感应加热线圈的电磁效应作用下形成内部涡流而发热，并且，其上的放电槽或放电孔发生放电现象，将水弱电解，使水分子的氢键断开，从而促进大分子团的水转化为小分子团水。使本实用新型的液体加热器成为有益于人体健康的新功能产品。 In the utility model, a discharge groove or a discharge hole can be set on the metal cylinder. When the induction heating coil generates a super-frequency electromagnetic field, the magnetic force line penetrates a non-magnetic container such as a borosilicate high-temperature glass pot, and performs high-frequency cutting on the water body in the container. The ring-shaped metal placed in the non-magnetic container forms an internal eddy current and generates heat under the electromagnetic effect of the induction heating coil, and the discharge groove or discharge hole on it generates a discharge phenomenon, which weakly electrolyzes the water and makes the water molecules The hydrogen bonds of the water are broken, thereby promoting the conversion of large molecular clusters of water into small molecular clusters of water. The liquid heater of the utility model is made into a new functional product beneficial to human health.
