Description

Automatic flue purifier for household

The utility model is a kind of range hood with fume purifying function, belongs to the technical field that household electrical appliance are made.

The major function of existing range hood or ventilating fan is to discharge the oil smoke in the kitchen, hot gas and toxic gas outdoor, but when discharging, these flue gases have directly polluted range hood and environment on every side, after long-term the use, the inside of range hood has been stained with thick greasy dirt, wall also is covered with grease spots around exhaust opening and its, has not only had a strong impact on the normal use of range hood, also severe contamination the environment around it.For on range hood, how purifying the waste gas that discharge in the kitchen, clean the range hood internal part simultaneously and make it neither to pollute range hood, do not pollute surrounding environment again, I have proposed all multi-schemes, but because the master-plan more complicated of these schemes, production cost is higher, is difficult for wide popularization and application.

Goal of the invention of the present utility model provides that a kind of gas cleaning is effective, liquid road simplicity of design, the reliable automatic flue purifier for household of frame for movement.

Automatic flue purifier for household of the present utility model is mainly by the smoke evacuation part, the water spray part, backwater processing section and electric control part branch are formed, wherein exhauster on the general structure be positioned at water jet above, the air inlet of exhauster and water jet exhaust outlet join, water tank is positioned at the water storage tank bottom of water jet, and by drainpipe and overflow pipe water tank is connected with water jet.Water tank is a casing that carries out backwater processing and standby water for cleaning, is provided with a water tank and a cleaning agent case in this water tank, and the cleaning agent case is connected with water tank by cleaning agent supply pipe.Be provided with a graded filter in water tank, be provided with draining valve in the bottom of water tank, the outlet of its draining valve is connected with the outlet pipe of water tank overflow pipe, and the water inlet of booster pump takes back water filter, and delivery port joins by pipeline and nozzle.The water inlet of water tank is located in the graded filter.

The course of work of the present utility model is: press fan switch, entering water electromagnetic valve is opened automatically, running water is ejected in the graded filter in the water tank by the water inlet of water tank by water inlet pipe, flow in the water tank by graded filter again, after the water in the water tank reaches certain water level, transmit signal by level sensor and close entering water electromagnetic valve automatically, and open booster pump and cleaning agent injection pump, close automatically after one stipulated time of cleaning agent injection pump work.During booster pump work, counter begins the working time of accumulative total booster pump simultaneously, and the water in the water tank is pressurized the pump suction and sprays from nozzle, and then gets back in the water tank, and the water in the water tank constantly circulates.After complete machine work reached official hour, draining valve is opened automatically carried out sewage discharge, and sewage has been arranged the back draining valve and closed automatically.The above-mentioned course of work repeats automatically, finished the overall process of cleaning, smoke abatement, filtration, discharging.

Advantage of the present utility model is:

That 1, cleans is effective.Gas by this clarifier is discharged does not have oil smoke substantially, and not only range hood itself does not have the pollution of oil stain, goes back and also purified surrounding environment.

2, the design of liquid road is more simple, reliable, and the water storage tank work liquid level in the water jet is by nozzle flow Q ₁With drainpipe flow Q ₂Difference guarantees; during shutdown; water in the water storage tank is drained by drainpipe; during work, about 30 second liquid level just remain on the overflow pipe height, after this; water in the water spray chamber is discharged to water tank from drainpipe and overflow pipe respectively; water storage tank keeps anhydrous clean conditions during shutdown, has simplified drain valve structure, and reliability obviously improves.

3, graded filter is designed in water tank, surround an enclosure space as graded filter with dividing plate filter and tank inner wall, simple in structure, increased the water tank useful space simultaneously, in addition, the running water water inlet pipe directly enters in the graded filter, by the back flush of press water, make graded filter non-maintaining, made things convenient for users.

4, drainage system and cleaning agent are added system and thoroughly separate, improved the reliability of complete machine, assembly structure is also simplified greatly.
