Background
The electric heater has been commonly used in places such as families, hotels and the like because of the advantages of portability, convenient use and the like, is more commonly used in places with damp and cool property and without heating in winter in south, and has wide use places.
The electric oil heater is also known as a common electric heater, and comprises a plurality of heater sheet structures, wherein each heater sheet structure comprises an upper oil pocket, a lower oil pocket and an oil way distributed on each heater sheet, and heat conduction oil is arranged in the upper oil pocket, the lower oil pocket and the oil way. The heating body heats the heat-conducting oil after being electrified, so that the heat-conducting oil transfers heat to the heater body structure and then transfers the heat to the surrounding environment.
However, when the electric oil-filled radiator works, the heat conducting oil is distributed in the oil discharging bag and the oil path channel, and a small amount of heat conducting oil is arranged in the oil discharging bag. When the heating part in the lower oil pocket heats, the heat conducting oil in the lower oil pocket is heated, the heat conducting oil transfers heat to the oil path channel, and the liquid level of the heat conducting oil in the upper oil pocket is boiled. During boiling, more hot bubbles move from bottom to top in the oil pocket. Therefore, the temperature of the upper oil coating part is relatively higher than that of the lower oil coating part.
In order to improve the use safety of the electric oil-filled radiator, a temperature limiter is usually arranged in the oil drain tank. When the temperature limiter senses that the ambient environment reaches the set temperature, the power supply of the heating body is cut off, and the heating is stopped continuously. But because the temperature of the upper oil pocket is relatively high, the temperature of the upper oil pocket per se exceeds the protection temperature set by the temperature limiter. Even after the power supply of the heating body is cut off, the heating body has residual temperature and can still heat the heat conduction oil, so that the heat conduction oil is continuously boiled for a period of time, the temperature of the oil applying package is continuously increased, the edge temperature of the heater body piece is continuously increased, and the temperature is easy to exceed the standard. Therefore, the temperature limiter is difficult to accurately control the temperature, and even the temperature exceeds the standard easily, so that the limited temperature of the limiter is set to be relatively low, and the situation of overtemperature is avoided, so that the warming effect of the warmer is poor.
