Energy-saving variable frequency electromagnetic heating steamer

Abstract

The invention discloses an energy-saving variable frequency electromagnetic heating steamer which comprises a water storage tank, a heat dissipator, a cooling circulating water pump, a high pressure water pump, a water inlet pipe, a water return pipe, a steam tank and a controller, wherein the controller comprises a power module, a control circuit board and a frequency converter. A single or a plurality of electromagnetic induction heaters connected in parallel or in series communicate between the water inlet pipe and the steam tank, the water inlet pipe communicates to the steam tank throughthe water return pipe, the water storage tank is connected to an external tap water pipe through a water inlet electromagnetic valve to supplement water, the water outlet of the water storage tank isconnected to the water inlet pipe through the high pressure water pump, the water outlet of the water storage tank is connected to an inlet of the heat dissipator through the cooling circulating waterpump, an outlet of the heat dissipator is connected to the water storage tank and the frequency converter clings to a heat dissipating face of the heat dissipator. An electromagnetic coil is electrified to electromagnetically heat a water flow and circulating cooling water is introduced to the heat dissipator to dissipate head of the frequency converter, and an electronic heating part is cooled and dissipated while the cold water is preheated, so that electric energy is utilized fully, and the energy-saving variable frequency electromagnetic heating steamer is high in steam generation speed and clean and sanitary.

Description

technical field [0001] The invention relates to the technical field of electromagnetic heating, in particular to an energy-saving frequency conversion electromagnetic heating steam engine. Background technique [0002] At present, coal, oil, steam, etc. are used in industrial production, food processing, heating, bathing, steaming, cooking, etc. where steam is needed, which consumes a lot of energy, has low thermal efficiency, and coal, oil, and steam are also harmful to the environment. create pollution. [0003] Electromagnetic heating technology is to use the principle of "skin effect" in physics to quickly heat iron materials, that is, high-frequency variable-frequency current passes through the coil to generate an alternating magnetic field. When iron is placed within the coverage of the coil's magnetic field lines, The ferrite body is cut by an alternating magnetic field, and an alternating current (ie, eddy current) is generated on the surface to heat rapidly. The e...

Problems solved by technology

The existing electric heating steam engine generally heats the electric heating tube directly by immersing it in water. The electric heating tube is easily scaled when soaked in water or exposed to water vapor for a long time and affects the heat exchange efficiency; long-term use is prone to safety hazards such as electrode corrosion. In severe cases, it may lead to electric leakage, explosion and other accidents
