Description
The utility model is a kind of range hood with fume purifying and automatic cleaning function, belongs to the technical field that kitchen appliance is made.
With regard to the range hood of prior art, roughly be divided into " vertical " and " horizontal " two classes, so-called " vertical " is basically perpendicular to kitchen range top face with regard to the axis that is meant blower fan, and being exactly the axis of blower fan, " horizontal " be basically parallel to kitchen range top face, having of this two class purified the applicant and the lampblack absorber of cleaning function is studied and improved, on the problem that solves inner cleaning automatically of range hood and purification of waste gas, the applicant has proposed all multi-schemes, and some has also applied for Chinese patent.The cooking fume remover of " vertical " type is because the restriction that is subjected to structure and designs, the smoke evacuation part, the water spray part, the backwater processing section is layering, cause blower fan from kitchen range top apart from each other, influenced range hood to effective suction waste gas produced on the kitchen range face, in addition, it is very inabundant to purify the aqueous vapor separation, and has some water to be discharged from.
It is big that goal of the invention of the present utility model just provides the effective soakage of a kind of waste gas, grease separating degree height, good purification, environment-friendly type range hood simple in structure, easy to operate.
Environment-friendly type range hood of the present utility model is by exhauster, spray thrower, and water tank, booster pump, the cleaning agent case, entering water electromagnetic valve, housing is formed.Exhauster is positioned at the upper back of housing, water tank is positioned at the rear lower of housing, spray thrower is fixed on the front upper part in the housing, air inlet is located at the front of spray thrower bottom, the cleaning agent case is fixed on lower end anterior in the housing, is provided with a loop product tank in spray thrower below air inlet, is connected by drainpipe and overflow pipe between water storage tank and the water tank, the water inlet end of booster pump is connected with water tank, and the water side is connected with the nozzle tube connector.The axis of blower fan is facing to air inlet, and the spout of nozzle is also facing to air inlet.In air outlet, be provided with a water fender, be provided with a circle ditch, be communicated with by return duct between ditch and the water tank in the lower edges of air outlet.Be provided with graded filter in water tank, the water inlet head is located in the graded filter, and the water inlet end of booster pump is arranged in this graded filter.Be provided with a draining valve in the bottom of water tank, the outlet of draining valve connects outer comb, and water tank full water ditch also is connected with outer comb by tube connector.Be provided with entering water electromagnetic valve in water inlet place, the import of entering water electromagnetic valve is provided with into water filter, and outlet is communicated with the water inlet head.
Its course of work is: after pressing power switch, exhauster work, entering water electromagnetic valve is opened automatically simultaneously, water tank water intake, when the water level of water tank reached certain height, entering water electromagnetic valve was closed, and opened booster pump and cleaning agent injection pump simultaneously, cleaning agent is injected in the water tank, after injecting certain amount, the cleaning agent injection pump is closed automatically, and the water in the water tank is pressurized the pump suction and sprays from nozzle, and then be back to water tank, so constantly circulation, when complete machine work behind official hour, draining valve is opened automatically, sewage discharge is gone out, close draining valve after sewage has been arranged.The above course of work repeats automatically, finishes the into overall process of water, cleaning, oil removing, filtration, discharging.
Its operation principle is: the waste gas that has an oil smoke enters spray thrower from the air inlet of spray thrower, at first with water storage tank in water meet, oil smoke is partially absorbed, because the suction of exhauster, the waste gas that has oil smoke continues to flow to the direction of exhauster, and the spray direction of spray thrower is opposite with the direction of air motion, therefore a large amount of oil smoke is absorbed by the water smoke in the spray thrower and takes away, after the oil flue waste gas of the preceding double purification of process enters exhauster, under the blower fan centrifugal action, the water smoke that will have greasy dirt is separated from the gas, liquid is thrown on the spiral case of exhauster, flows into water tank by return pipe again, and is last, residual water is fallen in the ditch by water fender again, go into water tank by return line flow, owing to have cleaning agent in the water smoke that from nozzle, sprays, therefore, in the process of purifying oil fume, air channel and the blower fan with whole range hood cleans simultaneously.
Advantage of the present utility model is:
1. the air inlet of spray thrower is arranged far apart from taking off the exhaust air inlet, and nozzle sprays to air inlet from spray thrower rear portion end face, and air-flow forms the convection current shape with water smoke, the spray zone greatly, gas-vapor mix is abundant, grease separating degree height, good purification.
2. water tank is fixed on the exhauster below, and spray thrower is fixed on exhauster the place ahead, the overall dimensions compactness.Simple in structure, moulding is good.
3. the exhauster blower fan can be arranged nearerly apart from the kitchen range top, and a dark type suspended hood is arranged, and the effective soakage of waste gas obviously improves.
4. cleaning agent tank is arranged on front lower place in the housing, is convenient to add cleaning agent and its amount of observation, and is easy to operate, makes things convenient for the user.
5. liquid road simplicity of design is intake, backwater, and draining, cleaning agent injects separate, the reliability height.
6. owing to be provided with a water fender, can not only further reduce damage by water, and make the gas of discharge cleaner at air outlet.
7. the design of water inlet head utilizes water feeding pressure back flush filter in backwater filters, and makes filter have self-cleaning function.
8. designed overflow pipe and drainpipe at spraying box water storage tank place, made the drainpipe flow less than nozzle flow, when guaranteeing spray thrower work, water storage tank has certain water level all the time, has increased purge segment.
