Description

Technical Field

[0001] The invention belongs to the technical field of energy-saving heat exchange devices, and in particular is an all-round energy-saving heating electric heater based on infrared radiation. Background Art

[0002] Electric heaters use electricity as the main energy source, and use resistance heating, induction heating, arc heating, electron beam heating, infrared heating and dielectric heating to heat the human body through direct contact, warm air convection, far infrared radiation, etc. They can be widely used in various civil and public buildings such as residential buildings, offices, hotels, shopping malls, hospitals, schools, train carriages, mobile heating, simple mobile houses, etc.

[0003] However, when electric heaters are currently used indoors, the existing electric heaters heat in one direction and cannot achieve all-round heating, so that a higher temperature can be felt near that direction, while other directions may be relatively cold, resulting in uneven temperature distribution in the space. At this time, users may feel obvious temperature differences when moving indoors, affecting their comfort. In addition, some old-fashioned or inefficient electric heaters have energy efficiency problems, that is, the ratio between the electrical energy they consume and the heat they generate is not high enough, resulting in energy waste and poor energy-saving effect. Therefore, an all-round energy-saving heating electric heater based on infrared radiation is proposed to solve the above problems. Summary of the invention

[0004] In order to solve the problems raised in the above background technology, the present invention provides an all-round energy-saving heating electric heater based on infrared radiation, which has the advantage of realizing all-round heating of the room through an electric heater based on infrared radiation, and applying the Stefan-Boltzmann law to adjust the power of the infrared radiation generator according to the infrared radiation intensity on the surface of the electric heater to achieve the effect of energy saving and consumption reduction, thereby solving the problems existing in the use of existing electric heaters.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an all-round energy-saving heating electric heater based on infrared radiation, comprising an electric heater shell, an infrared radiation generator is fixedly installed on the rear inner wall of the electric heater shell, the infrared radiation generator is also called an infrared radiator, and its working principle is that when the current passes through the infrared radiator heating wire made of special material, the heating wire will radiate infrared electromagnetic waves of a certain wavelength. When the infrared electromagnetic waves are absorbed by the object, the object is quickly heated. The operation of heating the object by using this technology is called infrared radiation heating technology; since each material has different absorption capacity for infrared rays of different wavelengths, in order to adapt to different materials, infrared radiators of different wavelengths can be produced by changing the winding method and material of the heating wire. At present, the commonly used infrared radiators mainly include short waves with a wavelength of about 0.76-2.0um, medium waves with a wavelength of about 2.0-4.0um, and long waves with a wavelength greater than 4.0um; since the thermal inertia of infrared radiation is very small, but the thermal efficiency is very high, Short-wave and medium-wave infrared radiation technology can be used to heat the workpiece with high density, high energy and high intensity, thereby improving the heating quality, shortening the heating time, saving energy, reducing heating energy consumption, saving production costs and reducing environmental pollution (the infrared radiation generator is an existing device, so it will not be described in detail here).

The control unit sends a second control instruction to the power adjustment unit. The power adjustment unit reduces the power of the infrared radiation generator according to the calculated proportional coefficient to reduce the infrared radiation intensity, achieve energy saving and consumption reduction, and avoid overheating of the electric heater.

The infrared radiation generator 2 is also called an infrared radiator, and its working principle is that when the current passes through the infrared radiator heating wire made of special material, the heating wire will radiate infrared electromagnetic waves of a certain wavelength. When the infrared electromagnetic waves are absorbed by the object, the object is quickly heated. The operation of heating the object by using this technology is called infrared radiation heating technology; since each material has different absorption capacity for infrared rays of different wavelengths, in order to adapt to different materials, infrared radiators of different wavelengths can be produced by changing the winding method and material of the heating wire. At present, the commonly used infrared radiators mainly include short waves with a wavelength of about 0.76-2.0um, medium waves with a wavelength of about 2.0-4.0um, and long waves with a wavelength greater than 4.0um; since the thermal inertia of infrared radiation is very small, but the thermal efficiency is very high, short waves, medium waves, and long waves can be used.

After the working time of the heating mechanism reaches thirty minutes, the acquisition unit 9 acquires the temperature data on the surface of the electric heater 3 and sends the temperature data to the analysis and processing unit 10. The infrared radiation intensity on the surface of the current electric heater 3 is calculated using the Stefan-Boltzmann law. , and the current infrared radiation intensity The infrared radiation intensity threshold is set for comparison, and based on the comparison result, the power adjustment unit 12 is controlled by the control unit 11 to adjust the power of the infrared radiation generator 2, and thereafter every ten minutes, the acquisition unit 9 will again collect the temperature data of the surface of the electric heater 3 to ensure that the infrared radiation-based all-round energy-saving heating electric heater can heat the room within the set range, thereby improving the performance of the equipment, user experience and energy saving.
