Description

Technical Field

[0001] The utility model relates to the technical field of steam generating devices, and belongs to an electromagnetic heating structure of a steam generating device. Background Art

[0002] The electromagnetic heating structure of the steam generator is a device that uses the principle of electromagnetic induction to heat water and generate steam. Its working principle is to generate an alternating magnetic field in the heating element through alternating current. When a metal container is placed in it, eddy currents will be generated on the container wall, causing the container itself to heat up, and then transfer the heat to the water inside, causing it to boil and generate steam. The advantages of electromagnetic heating include high thermal efficiency, fast heating speed, energy saving and environmental protection. At the same time, since the heating element is not in direct contact with water during electromagnetic heating, it is safer.

[0003] For example, the prior art publication number is CN214064867U, which is an electromagnetic heating structure of a steam generating device. The annular heating cavity of the utility model is arranged inside the gasification furnace, and the heating speed is fast and the efficiency is high; the heating tube is fixed in the annular heating cavity by a fixture, and the heating tube is energized to heat the annular heating cavity, and the annular heating cavity heats the water in the gasification furnace to generate steam, and the heating range is wide and the heating is uniform; there is a gap between the lower part of the annular heating cavity and the furnace wall of the gasification furnace, so that the water level of the outer annular cavity and the inner annular cavity are at the same height.

[0004] However, the above-mentioned prior art still has the following problems when used: after long-term use, scale will form on the inner and outer wall surfaces of the annular heating cavity, and the scale will hinder the conduction of heat. Therefore, it is necessary to frequently stop the machine and disassemble the annular heating cavity for cleaning. Once the amount of water inside the steam generating device is reduced, the surface of the annular heating cavity is prone to dry heat, and will be damaged when encountering cold water, which will affect the service life. Based on this, the utility model provides an electromagnetic heating structure of a steam generating device that can automatically clean scale and has a long service life. Utility Model Content

[0012] Furthermore, two mounting tubes are fixedly passed through the bottom end of the hollow tube, and the bottom ends of the two mounting tubes pass through the bottom end of the steam generating device. The bottom end of the electromagnetic heating coil passes through the mounting tubes to prevent the electromagnetic heating coil from directly contacting water.

[0013] Furthermore, a ring plate is provided inside the water inlet pipe, and a filter net is fixedly provided inside the ring plate for filtering impurities in the water to prevent the impurities from clogging the high-pressure water pump and the nozzle.

[0014] Furthermore, a detachable sealing plate is fixedly provided on the top of the hollow tube, and the electromagnetic heating coil is fixed to the detachable sealing plate, so that it is convenient for the staff to disassemble the electromagnetic heating coil and perform maintenance and replacement on the electromagnetic heating coil.
