Description

technical field [0001] The invention relates to an electric heating appliance, in particular to an ultra-energy-saving and safe intelligent electric heater. Background technique [0002] Electric heaters, especially movable box-type (usually open wooden box) electric heaters (electric heating fire boxes) with a footrest mechanism, because of their convenience in heating, especially in the way of warming feet , in line with the principle of cold from the feet in traditional Chinese medicine and the reality of dehumidification in the south, it is more and more popular among people. This heating method can improve the blood circulation of the feet and legs, and can prevent rheumatism and foot pain. [0003] The disadvantages of existing electric heaters, especially the controllers (electric heating fireboxes) used for movable box-type electric heaters, are large power consumption, large waste of electric energy, large gaps in temperature control, and violent temperature changes...

Problems solved by technology

[0003] The disadvantages of existing electric heaters, especially the controllers (electric heating fireboxes) used for movable box-type electric heaters, are large power consumption, large waste of electric energy, large gaps in temperature control, and violent temperature changes. Large, affecting the comfort of heating, the safety and durability of the control circuit is not enough, it is easy to burn out and cause major safety accidents such as fire

[0004] On the one hand, in the existing temperature control device for movable box-type electric heaters, only one integral circuit board is set in the control panel where switches and indicating and displaying elements are installed, including silicon controlled rectifiers and other electronic devices that produce large heat. Components and other electronic components are all concentratedly installed on such a small circuit board. Since the existing temperature control device is attached to the side box board of the electric heating fire box, the components in the temperature control device are between the side box board and the side box board. Between the heating elements, there is no heat insulation layer between the components in the temperature control device and the high temperature area around the heating element. The installation place of the components in the temperature control device is often in the high temperature area. Electronic components such as electronic components have a large load-carrying power and produce a lot of heat. It is difficult to achieve the specified heat dissipation purpose through the existing heat sink. Other components on the circuit board are easy to age or burn out, which often causes the temperature control device to burn out easily and is not durable, which can easily lead to major safety accidents such as fire

[0005] On the other hand, the existing electric heater adopts thermistor timing control or potentiometer stepless temperature adjustment control. According to the rated power of the heater, the heater is turned on and off with the full rated power to make the heater realize the so-called constant temperature, and Very high frequency of on and off

This kind of full-load rated power is frequently turned on and off, the temperature increases and decreases violently, and the inertia of heating or cooling is very large, which often deviates from the heating comfort temperature value by a large amount, which not only reduces the heating comfort (often produces a burning sensation) or cold feeling), and waste a lot of electric energy; secondly, frequent power-on at full-load rated power, sudden heating or sudden stop of heating when power is off, large starting current, which also increases heating power consumption; thirdly, frequent power-on at full-load rated power , power failure, the impact on the controller is large, and it is easy to cause arc oxidation or burnout at the circuit connection, which greatly reduces the service life of the controller, and often leads to major safety accidents such as fire, and has a negative impact on the associated power grid, electrical appliances also has a great influence
