Range hood module with electromagnetic heating de-oiling

Abstract

The invention discloses a range hood module with electromagnetic heating de-oiling. The range hood module comprises an electromagnetic heating module, a motor control module and a temperature acquisition control module, wherein charging and discharging are carried out on the BR1-rectified direct current voltage of municipal electricity by an IGBT (Insulated Gate Bipolar Translator) under the control of a single-chip microcomputer, inducing current is produced when a magnetic field produced by a coil disc cuts the surface of a worm gear blade, and heating is carried out by utilizing a current heat effect; a motor rotates under the control of the single-chip microcomputer, so that the metal surface of the blade is uniformly heated, and the rotating of the blade is accelerated after the bladeis controlled to periodically rotate for multiple circles; the temperature acquisition control module is used for transmitting acquired temperature back to the single-chip microcomputer; and when theacquired temperature is too high, electricity is cut off to cancel heating, and the motor is started. Compared with the prior art, the range hood module has the advantages that electromagnetic heating is used, electromagnetic de-oiling is realized, and direct heating isolating is realized; by heating the worm gear blade, oil dirt is rapidly molten, the oil dirt is tossed away when the blade rapidly rotates, and de-oiling is realized; and through the temperature acquisition control of a closed-loop NTC thermistor, heating safety is ensured.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a range hood module equipped with electromagnetic heating and degreasing. Background technique [0002] As the range hood is used more often, there will be more and more internal oil stains. If the internal oil stains cannot be completely removed, the accumulated oil stains will reduce the satisfaction of using the range hood for degreasing. At present, the degreasing functions of range hoods in the market are commonly used for steam degreasing, heating film degreasing and high-speed oil removal. The degreasing speed of the scheme is slow and the effect is poor, and the oil stains on the hood cannot be removed cleanly. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a range hood module equipped with electromagnetic heating for degreasing. [0004] The present invention is achieve...
