There are many kinds of electric heaters, and the types of electric heaters used in different regions and different temperature environments are also different.
At present, heating in winter in northern China is mainly central heating, which requires a large amount of hot water, which wastes water resources as well as coal resources, and does not conform to the social theme of energy conservation and environmental protection advocated at present, at the same time, most areas in southern China adopt electric heating equipment, but most of the traditional electric heating equipment has a single structure, which can only achieve local heating, but cannot achieve the effect of overall heating, with low heating comfort and low heat exchange efficiency. As a result, the energy utilization rate is not high, and although some existing liquid-filled heaters have an overall warming effect, they need to be filled with heat transfer oil, which leads to heavy weight and slow warming, which results in low user satisfaction. In addition, some heating equipment like air conditioners and heaters have the problems of heavy dust and high noise, and have low use comfort.

DESCRIPTION OF THE INVENTION In order to deepen the understanding of the present invention, the present invention will be further described in detail with embodiments below. The embodiment is only used to explain the present invention, and does not constitute a limitation on the scope of protection of the present invention.
According to Figs. 1, 2 and 3, the embodiment provides a pipeline-free and liquid- free electric heating structure, which comprises an electric heating element 1 and a baffle 2, wherein the electric heating element 1 is arranged inside the baffle 2, and the left and right ends of the electric heating element 1 are respectively installed on the inner walls of the left and right sides of the baffle 2, and the front and rear sides of the electric heating element 1 are provided with radiating fin 3, the cross section of which is wave-shaped and the left and right ends are respectively fixed on the inner walls of the left and right sides of the baffle 2. The lower end of the radiating fin 3 extends to the outside of the baffle 2, and a thermal channel 4 is formed between the front and rear sides of the radiating fin 3 and the inner wall of the 5 baffle 2 and the electric heating element 1. Ultraviolet germicidal lamps 5 are installed on the front and rear inner walls of the baffle 2, a dust filter 6 is installed on the bottom end of the baffle 2, and a temperature regulating module 7 is installed on the electric heating element 1. The left and right sides of the temperature regulating module 7 are provided with temperature sensors 8 installed on the electric heating element 1, and the temperature sensor 8 is connected with the PLC control system of the electric heating, which is used to drive the temperature regulating module 7 to adjust the heating temperature of the electric heating body
1.
An insulating plate 9 is arranged between the electric heating element 1 and the radiating fins 3, and the left and right ends of the insulating plate 9 are respectively fixed on the left and right inner walls of the baffle 2, and the insulating plates 9 are symmetrically distributed on the front and rear sides of the electric heating element 1, which plays an insulating role and improves safety.
A leakage protector 10 is installed on one side of the electric heating element 1 away from the temperature sensor 8, and current sensors 11 installed on the electric heating element 1 are installed on the left and right sides of the leakage protector 10, and the current sensors 11 are connected with the PLC control system of the electric heating element for driving the leakage protector 10 for leakage protection when the current is abnormal.
The front of the baffle 2 is provided with a fault indicator lamp 12 and a temperature display 13 respectively. The current sensor 11 is connected with the PLC control system of the electric heating element for turning on the fault indicator lamp 12 when the current is abnormal, and the temperature sensor 8 is connected with the PLC control system of the electric heating element for controlling the temperature display 13 to display the temperature.
Cylindrical through holes 14 are equidistantly formed in the side wall of the baffle 2, and rock wool insulation layer 15 is filled in the side wall of the baffle 2 except for the through holes 14, which plays a role in heat preservation and avoids heat transfer from the side wall of the baffle 2.
The left and right sides of the front and rear ends of the baffle 2 are fixed with support plates 16, and the bottom ends of the support plates 16 are fixed with support legs 17, so that the electric heating element is more stable in use.
Upper mounting block 18 are fixed at four sides of the lower part of the baffle 2, and lower mounting block 19 matched with the upper mounting blocks 18 are fixed at four sides of the upper part of the dust filter screen 6. The upper mounting block 18 and the lower mounting block 19 are locked and connected by locking bolts 20, which is convenient for mounting and dismounting the dust filter screen 6, thus facilitating regular cleaning of dust on the dust filter screen 6. When the electric heating element needs to be used, the electric heating element 1 is first electrified to release heat, so that the cold air in the thermal channels 4 at the front and rear sides of the radiating fin 3 is indirectly heated. Because the density of hot air decreases, the air flows upward through the thermal channels 4 after being heated, while the cold air fills the space left by the hot air flowing away, and is absorbed into the thermal channels 4 at the front and rear sides of the radiating fin 3 from the bottom end of the baffle 2 and heated into hot air in the radiating fin 3. Continue to flow upward along the thermal channel 4. At the same time, the hot air that has flowed out of the radiating fins 3 meets the cold air outside the baffle 2. After cooling, the density increases and gradually sinks, thus continuously circulating, forming natural convection of air to increase indoor temperature. In the heating process, the ultraviolet germicidal lamp 5 is turned on to sterilize the air, while the dust impurities in the air are intercepted by the dust filter 6. In addition, the heating temperature of the electric heating element 1 is adjusted by the temperature regulating module 7 during heating. The pipeline-free and liquid-free electric heating structure comprises an electric heating element 1 and a baffle 2, wherein the electric heating element is arranged inside the baffle. According to the invention, the indoor temperature is rapidly increased by effectively utilizing the principle of natural convection of air, the air is heated without a pipeline, and the interior does not need to be filled with liquid such as heat transfer oil, so that the production cost of the electric heating element is reduced and the electric heating element is convenient to use, troubles possibly encountered in use are avoided, and no light pollution or silent pollution exists.
The radiating area of the radiating fins 3 is increased by arranging the radiating fins 3 into a wave shape, the contact area of heated air and the air quantity in the thermal channel 4 are increased, and the temperature-raising efficiency is improved.
The convection speed of air is enhanced by the narrow space formed between the baffle 2 and the radiating fins 3, thereby increasing the frequency of heat exchange.
The air is sterilized by ultraviolet germicidal lamps 5, and the dust impurities in the air are intercepted by dust filter screen 6, thus making the hot air cleaner and healthier.
In addition, the temperature in the electric heater is sensed by the temperature sensor 8, and the heating temperature of the electric heating element
1s adjusted by the temperature regulating module 7, so that the temperature of the electric heater is convenient for intelligent adjustment, and the use comfort is improved.
