Abstract

The utility model discloses a high pressure water current washout type self cleaning smoke exhaust ventilator, belonging to a pumping drainage smoke exhaust ventilator of kitchen, in particular, the utility model discloses a smoke exhaust ventilator which can automatically clean a blade wheel and the inner cavity of a spiral casing. The air inlet of the smoke exhaust ventilator is additionally installed with a movable seal gate. When the smoke exhaust ventilator is cleaned, the air inlet of the spiral casing can be sealed, and then pressurized cleaning fluid is made to evenly sprayed to the blade wheel of the smoke exhaust ventilator from the position of the side surface of the spiral casing which is nearest to the blade wheel, under the drive of a swing mechanism, the cleaning fluid of a sprayer can wash the position of easy scale formation which adheres to the inner part of the smoke exhaust ventilator with high pressure and clean all the components adhering to greasy dirt in the sealed spiral casing.

Description

The High-Pressure Water flushing type cleans lampblack absorber automatically

Technical field

The utility model belongs to the fume exhausting fan in kitchen, particularly a kind of automatic washing lampblack absorber that can clean impeller and spiral case inner chamber automatically.

Technical background

At present the lampblack absorber of listing is because the particularity of its structure and service condition, uses for a long time and do not clean the impeller that will cause lampblack absorber and adhere to thick grease, the exhausting effect of lampblack absorber is significantly descended, so lampblack absorber needs regularly to clean parts such as impeller.It is a thing time-consuming, that effort makes user's headache that yet the inside of lampblack absorber is cleaned, and therefore, the manufacturer of lampblack absorber pays attention to relevant cleaning aspect The Application of Technology especially when the exploitation lampblack absorber.

The what is called of Chu Xianing " exempts to unpick and wash " lampblack absorber in the market, on structure, just the air inlet of common lampblack absorber added one can disassembly, cleaning the metal filtration guard, can filter out a part of oil smoke, reduce the degree of fume pollution lampblack absorber internal structure.But from practical effect, the effect of screen pack is to filter out a part of oil smoke and can not filters out the oil smoke that enters lampblack absorber fully, so the parts of lampblack absorber inside still are subjected to the pollution of oil smoke, thereby has influenced the result of use of lampblack absorber; Simultaneously, because screen pack itself has been subjected to the pollution of oil smoke, when using to a certain degree, oil smoke adheres on the screen pack, thereby will stop up the suction that mesh reduces lampblack absorber greatly.It is undisputable fact that the screen pack of therefore " exempting to unpick and wash " lampblack absorber needs often to clean.On the other hand, it seems that the impeller of " exempting to unpick and wash " lampblack absorber still has been subjected to pollution, still need regularly to clean from the situation of principle and use.So, the effect of " exempting to unpick and wash " lampblack absorber just will originally need regularly to clean easy corresponding prolongations of more loaded down with trivial details working time that pollute parts such as lampblack absorber impeller, generation in cleaning and filtering net frequently relatively than gravy jobs, from this effect, " exempt to unpick and wash " lampblack absorber certain positive effect is still arranged, yet, can't really fully the consumer be freed from the work of cleaning smoke extractor.

Though have some at present the design of the automatic cleaning lampblack absorber of cleaning fluid is housed, but greasy dirt has very strong adhesive force, therefore find in test that still there is the problem that does not wash clean in these designs, this also is that the main cause promoted to practicability is failed in these designs now.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of lampblack absorber device of automatic cleaning, and it is simple in structure, can make smoke extractor in the short as far as possible time, uses the least possible cleaning fluid, cleans up inner easily fouling position effectively automatically.

Solving the scheme that technical problem of the present utility model adopts is: at the air inlet place sealing up a door of air inlet is housed, the high-pressure water nozzle of band swing mechanism is housed in the spiral case sidewall position nearest apart from impeller, and shower nozzle is reverse facing to the wheel rotation direction.

When lampblack absorber normally used, air inlet was opened, and kept the unimpeded of air-flow; During cleaning, air inlet sealing with spiral case, prevent cleaning fluid leakage pollution indoor environment, the cleaning fluid of the shower nozzle that is installed in the spiral case sidewall simultaneously after with supercharging is to spray against the direction of impeller rotation, the position nearest apart from impeller from spiral case sprays to the impeller that is rotating, and swing mechanism is also driving shower nozzle and is swinging, and the surface of whole blade all is washed into.In this case, the flushing of cleaning fluid after the supercharging and be adsorbed on the impeller after, dissolving sticks to the grease on the impeller, under the action of centrifugal force that impeller rotates at a high speed, get rid of then to the spiral case inner chamber, simultaneously, at a high speed the impeller of rotation can also blow to spiral case with the part cleaning fluid, and these cleaning fluids can get rid of grease after the dissolving of spiral case with impeller, flow into lubricating cup along the spiral case internal chamber wall.This kind action ceaselessly acts on impeller, just can wash the grease that sticks on impeller and the spiral case inner chamber fully, reaches the purpose of automatic cleaning.

The booster of cleaning fluid can adopt electric booster, and the flow at shower nozzle place should reach 1 liter/hour～10 liters/hour during work, and the pressure of cleaning fluid should reach 1kg/cm ²～3kg/cm ², the scope of shower nozzle 5mm～50mm under the impeller outer edge.

This cleaning of cleaning lampblack absorber automatically can be finished by computer controller control.The computer programming thinking is to combine with the time length that lampblack absorber uses according to the full number of times of lampblack absorber lubricating cup oil, automatically provide the signal that needs cleaning by lampblack absorber, remind the user to prepare to clean lampblack absorber, like this, just can avoid the user not clean the cigarette machine for a long time and make that the grease of lampblack absorber is many and do, the effect of automatic cleaning is had a greatly reduced quality; The startup that can avoid again simultaneously cleaning automatically influences user's normal use, perhaps avoids the user to prepare deficiency and causes the lubricating cup waste liquid to overflow to leak outside; Pollute the kitchen range top.

The beneficial effects of the utility model are, the cleaning fluid of supercharging can be in semi-enclosed spiral case, thread form with high pressure and scanning is carried out the more cleaning of large impact power to the position of impeller, the easy structure of spiral case, thereby reaches the purpose that cleans up impeller and spiral case inwall simultaneously.
