Description

Oil-removing and rust-preventing range hood

Technical Field

The invention relates to the technical field of intelligent home furnishing, in particular to a deoiling and rust preventing range hood.

Background

The kitchen ventilator is also called as a range hood, and is a kitchen appliance for purifying the kitchen environment. The kitchen ventilator is arranged above a kitchen stove, can rapidly pump away waste burnt by the stove and oil smoke harmful to human bodies generated in the cooking process, and exhaust the oil smoke out of a room, and simultaneously condenses and collects the oil smoke, thereby reducing pollution, purifying air and having the safety guarantee effects of gas defense and explosion prevention.

Because the oil mist separation is carried out through the filter screen and the oil pan in the range hood, oil stains on the filter screen are more and are more concentrated on the upper side in actual use, and water vapor on the lower side is directly contacted with the filter screen to be cooled and liquefied into water drops and is condensed on the filter screen under the adhesion effect of oil, so the rusting phenomenon is easy to occur.

Disclosure of Invention

The invention aims to solve the problems that a water dispenser cleaning device in the prior art is complex to operate and does not have an automatic cleaning function, and provides an oil-removing and rust-preventing range hood.

In order to achieve the purpose, the invention adopts the following technical scheme: a deoiling and rust-proof smoke exhaust ventilator comprises a shell, an exhaust fan and an air inlet hole, wherein a filter screen is arranged on the inner wall of the shell, a liquid tank is arranged at the bottom of the shell, two air outlets are respectively formed in two sides of the liquid tank, an air outlet pipe is hermetically connected in each air outlet, the filter screen is connected with a transmission structure, two side walls of the shell are respectively provided with a sliding cavity, and one end, far away from each air outlet, of the air outlet pipe is communicated with the sliding cavity;

the transmission structure comprises sliding blocks welded at two ends of the filter screen, a groove with the size matched with that of the sliding block is formed in the part, close to the sliding block, of the side wall of the shell, the top of the groove is fixedly connected with the top of the sliding block through a spring, an electric magnetic strip is arranged at the bottom of the groove, two ends of the electric magnetic strip are slidably connected with the groove through a T-shaped structure, and the magnetic strips abut against the top of the filter screen;

the sliding cavity is connected with a magnetic block in a sealing and sliding mode, the magnetic block is opposite to the different poles of the electromagnetic strips, an exhaust channel is formed in the top of one end, away from the magnetic block, of the sliding cavity, and the other end of the exhaust channel is communicated with the side wall, located on the upper side of the filter screen, of the shell.

In the rust-resistant smoke ventilator of deoiling, the liquid case sets up to funnel type structure and is equipped with the opening, all sealing connection has the check valve in opening, the inlet port and the outlet duct, the liquid incasement is equipped with the solvent, the bottom fixedly connected with hot plate of liquid case.

In the oil-removing and rust-preventing range hood, the sliding block is of a metal conductor structure and is communicated with external conductive equipment, and the electric magnetic strip is communicated with the heating plate.

Compared with the prior art, the invention has the advantages that:

1. according to the invention, the weight of the suspended filter screen is increased under the accumulation of oil stains to serve as the power for starting the device, after the filter screen is subjected to a large amount of oil mist separation, more oil mist is generally arranged on the upper side of the filter screen, and more water is arranged on the lower side of the filter screen, so that after the filter screen is used for a long time, the whole weight of the filter screen is increased, a larger pulling force is generated on a spring to enable the position of the spring to descend, and finally the filter screen is contacted with an electromagnetic strip to enable the electromagnetic strip to;

2. the heating plate heats a solvent in the liquid tank, the solvent has the characteristics of low boiling point and similarity and compatibility with food oil, and the solvent enters the sliding cavity through the air outlet pipe after being heated, so that the magnetic block in the sliding cavity slides to the other side under the action of air pressure, the magnetic block is made of neodymium iron boron material, and the magnetic block has the advantage that the electromagnetic strip generates stronger magnetic attraction force, so that the electromagnetic strip slides along with the magnetic block when the magnetic block slides, and the lower end face of the filter screen is cleaned;

3. meanwhile, the solvent vapor entering the sliding cavity enters the space above the filter screen in the shell through the exhaust channel and is liquefied into solvent liquid again in the contact of the filter screen, and the solvent liquid is similar to and compatible with the edible oil, so that the food oil can be dissolved by the solvent, and the thickness of an oil layer deposited above the filter screen is reduced;

4. meanwhile, the magnetic strips abutted against the upper end of the filter screen are mutually attracted with the electromagnetic strips in the state that the electromagnetic strips are electrified, so that the upper end surface of the filter screen is cleaned while the electromagnetic strips slide, the friction between the magnetic strips and the filter screen is increased under the mutual attraction effect of the magnetic strips and the filter screen, and the cleaning degree and the water absorption effect of the filter screen are increased by arranging the elastic rubber layer, so that the two sides are simultaneously cleaned;

5. and when the upside that the oil reservoir is thick is cleaned, will have partial food oil to get into terminal surface under through the filtration pore, make when in actual use, the cleaning of terminal surface under the filter screen can the feeder lower surface adhere to the lighter and thinner oil reservoir of one deck, and absorb water the operation simultaneously, make the difficult emergence rust phenomenon of terminal surface under the protection of light and thin oil reservoir down, and through the absorption to water on the rubber layer, and the esterification reaction of oil to acid, reduce electrochemical corrosion's production.

6. After filter screen weight reduction, under spring force effect, the slider breaks away from the contact with the electric magnetic stripe, then finishes the heating to the liquid tank for solvent and the dissolved oil in the casing enter into the liquid tank through the export simultaneously, and can continue to use when next oil reservoir increases.
