Description
Technical field
The present invention relates to a kind of range hood for kitchen, specifically the closed lampblack absorber of a kind of automatic lifting.
Background technology
In the food processing in cuisines field, fried, fried, cooked, fried occupy very large ratio, therefore the oil smoke in Chinese style kitchen is very large, kitchen environment is easily made to become greasy and bad cleaning, and the oil smoke produced in culinary art contains harmful material, people works for a long time in the environment being full of oil smoke, may cause the generation of disease, and lampblack absorber is a kind of comparatively universal field of kitchen electric appliance equipment, for discharging the oil smoke produced in cooking stove cooking process.Lampblack absorber, in smoke discharging process, has carried out the process of an Oil-gas Separation, directly enters air pollute to avoid oil-containing gases, in this process, oil gas advanced person crosses one deck filter screen, now, oil droplet will condense upon on filter screen, and in the lubricating cup be dropped in below filter screen through water conservancy diversion; And the gas after filter screen, still containing more oil molecule, after the High Rotation Speed of blower fan, under the influence of centrifugal force, there is Oil-gas Separation in this gas, and oil droplet will get rid of to surrounding, pollute.
Traditional lampblack absorber is generally the side-suction type range hood adopting centrifugal blower, side-suction type range hood is that the air inlet of blower fan is in the side of envelope inner chamber, oil smoke enters blower fan by side air inlet mouth, then be separated by oil smoke, oil smoke after being separated is discharged to outdoor by flue, in general, centrifugal blower costly, during side-suction type range hood work, noise is larger, there is a lot of clean dead angle, and the safety net of most of side-suction type range hood is open, namely filtration oil network is not set, oil smoke directly enters in blower fan, and be attached on the inwall of impeller in blower fan, greasy dirt on impeller is difficult to cleaning, easy generation motor load increases, the problem that power consumption increases and oil sucting force reduces.Simultaneously, traditional lampblack absorber, its wind gathering hood is generally the unenclosed construction being provided with wind gathering chamber, the oil smoke that kitchen range produce can not be gathered and be closed, lampblack-pumped poor effect, the existing lampblack absorber through improving such as the such as authorized utility model of State Patent Office, the patent No. are a kind of smoke exhaust ventilator of ZL201020287640.2, that oil baffle is set in the dead ahead of lampblack absorber casing and the left and right sides, oil baffle snaps onto in the button hole of casing by clasp, although dismounting more for convenience, such setting takes up room.
Summary of the invention
For noise when solving in prior art the lampblack absorber work existed is large, oil smoke can not be difficult to the defects such as cleaning by the greasy dirt that exists on the high and impeller of clean dead angle, cost of self-closed, lampblack absorber, the invention provides the closed lampblack absorber of a kind of automatic lifting, the oil baffle of this device achieves the effect to oil smoke self-closed, and structure is simple and easy to operate.
The present invention for the adopted technical scheme that solves the problem is: the closed lampblack absorber of a kind of automatic lifting, comprise body, blower fan and automatic lifting locking device, the air inlet of described body is provided with screen pack, the below of screen pack is provided with lubricating cup, described blower fan is by spiral case, the impeller and the motor that are located at spiral case inside are formed, spiral case comprises volute and is located at epipleural and the lower side panel of lower bottom part on volute respectively, wherein, epipleural and motor are connected, lower side panel is provided with into mouth, described impeller is arranged in spiral case in the mode that it is axially perpendicular to described side plate, the side extension of described volute is provided with pipe, the flue of pipe rises in spiraling and arranges, the inwall of pipe and spiral case are fitted, the axis of the outlet flue of pipe is vertical with side plate, and the outlet flue of pipe towards with enter the towards the opposite of mouth.
Described automatic lifting locking device comprises two pieces of oil baffles, baroceptor and lifting drives, two pieces of oil baffles are symmetricly set on the both sides of body, two pieces of oil baffles realize synchronization lifting motion by lifting drive, the signal output part of described baroceptor is connected with lifting drive, and the signal input part of baroceptor is communicated with spiral case by wireway.
The flue of described pipe rises in the helical that spirals and arranges, and the elevation angle of helical is 25-75 °.
The flue of described pipe rises in the helical that spirals and arranges, and the elevation angle of helical is 30-50 °.
The present invention, by lifting drive in order to control the synchronization lifting motion of oil baffle, the signal input part of baroceptor is communicated with spiral case by wireway, in order to detect the air pressure change in spiral case, when in spiral case, the air pressure of air-flow acquires a certain degree, baroceptor sends signal makes lifting drive open, control oil baffle automatically to decline, now, the oil baffle of lampblack absorber body and the body left and right sides forms the enclosed construction of oil smoke, the waste gas that kitchen range are produced and oil smoke come together gathering, avoid causing working environment to produce oil pollution, when lampblack absorber quits work, spiral case internal gas flow reduces until disappear, now baroceptor sends signal lifting drive is opened, control oil baffle automatically to rise, owing to adopting baroceptor, the elevating movement of oil baffle is controlled by the air pressure change in spiral case, this device can produce time-lag action, namely after lampblack absorber quits work, oil baffle can not rise immediately, but the air pressure in spiral case drops to a certain degree, baroceptor just sends signal, control oil baffle rises, achieve the object of fully suction oil smoke, reduce fume pollution to greatest extent.
The present invention, the spiral case of impeller periphery comprises volute and is located at epipleural and the lower side panel of lower bottom part on volute respectively, and volute portion can play the guiding role to the flowing of spiral case apoplexy, and reduce the energy loss of blower fan work, air draft is comparatively steady, pipe is located at the mouth direction, whirlpool in volute portion, and the flue of pipe rises in spiraling and arranges, and this structure not only can eliminate the vortex phenomenon that in housing, wind body produces, vibrations during blower fan work can also be reduced, reduce noise, simultaneously, without dead angle when clean, clean comparatively thorough, the axis of the outlet flue of pipe is all vertical with side plate with the axis of impeller, the principle that such vibrational power flow utilizes oil smoke naturally to rise, oil smoke is retracted to and is formed in the enclosed construction of oil smoke by the oil baffle of lampblack absorber body and the body left and right sides, discharge after filtering outside body, when oil smoke rises naturally, the oil smoke of part directly filters on the screen pack of lampblack absorber body, realize preliminary filtration, the pollution of oil smoke to impeller can be alleviated, and under the oil smoke that impeller the adheres to centrifugal action of rotating at blower fan, be thrown to the inwall of housing, inwall along housing glides and imports in lubricating cup.
Beneficial effect: the flue of the pipe of this lampblack absorber rises in spiraling and arranges, and this structure not only can eliminate the vortex phenomenon that in housing, wind body produces, and can also reduce vibrations during blower fan work, reduce noise, meanwhile, without dead angle when clean, clean comparatively thorough; This lampblack absorber can realize the enclosed construction of oil baffle and lampblack absorber body, effectively can reduce the flowing of oil smoke air, stop oil smoke to the pollution of working environment, and employing send signal in order to control oil baffle lifting by the baroceptor of the air pressure in spiral case, has time-lag action; This range hood structure is simple, operates steadily, shakes little, realizes the closing of oil smoke, confluxes and gather and in line effect, and rapidly, thoroughly, and cost is lower for smoke pumping.
