Electromagnetic heating device for water dispenser

Abstract

The invention provides an electromagnetic heating device for a water dispenser, which comprises a hollow insulating skeleton, an enamelled wire coil and a hollow metal heating body, wherein a spiral line groove is formed on the outer surface of the insulating skeleton; the enamelled wire coil winds in the spiral line groove of the insulating skeleton; the metal heating body is arranged in the insulating skeleton; the insulating skeleton has a strip shape, and the metal heating body has a strip shape; and the metal heating body and the insulating skeleton are arranged in parallel. In the electromagnetic heating device for the water dispenser, due to the utilization of the ultrasonic electromagnetic heating principle, drinking water in daily life can be boiled and magnetized by non-inner container electromagnetic heating, so that people do not drink residual water, unboiled water and repeatedly-boiled water, the water can be drunk while being boiled, and the quality of drinking water isimproved; and the electromagnetic heating device is favorable for the health of the drinking water, has the advantages of high heating speed, high heat efficiency, long service life, safety, reliability and the like and is difficult to scale and water and electricity are completely separated.

Description

technical field [0001] The invention relates to a water dispenser, in particular to an electromagnetic heating device for a water dispenser. Background technique [0002] At present, most water dispensers on the market are heated by resistance wires, that is, usually after the resistance wires are insulated and packaged, they are put into certain metal material containers, and the heat generated by the resistance wires is used to heat the water in the metal containers. Heating; in this water dispenser, due to technical and structural problems, it is impossible to heat the water to the boiling point, so it can only be used to heat treated bottled water, and the cold water is continuously injected during use , most of the drinking water is hot and cold mixed water, and this common heating method and device will also cause scaling, which will eventually result in a short service life of the water dispenser, which is unsafe, and long-term drinking of water from this water dispen...

[0002] At present, most water dispensers on the market are heated by resistance wires, that is, usually after the resistance wires are insulated and packaged, they are put into certain metal material containers, and the heat generated by the resistance wires is used to heat the water in the metal containers. Heating; in this water dispenser, due to technical and structural problems, it is impossible to heat the water to the boiling point, so it can only be used to heat treated bottled water, and the cold water is continuously injected during use , most of the drinking water is hot and cold mixed water, and this common heating method and device will also cause scaling, which will eventually result in a short service life of the water dispenser, which is unsafe, and long-term drinking of water from this water dispenser is not conducive to human health

[0003] In recent years, there are also water dispensers heated by glass tubes. It is coated with a conductive metal film on the outside of the glass, uses the external metal film to heat the glass tube, and then heats the drinking water source through the glass tube, and the water is heated to boiling and then the water comes out; This heating method and heating device have poor heat conduction, the glass tube is fragile, and the power attenuation is serious. It is difficult to meet the drinking water requirements of most people in terms of water output speed and water output.
