Description
Technical Field
The utility model relates to a kitchen guarding's household electrical appliances field, an easy washing lampblack absorber specifically says so.
Background
With the continuous improvement of the living standard of people, the annual average consumption of edible oil is rapidly increased, so that the oil pollution of the kitchen range hood is serious, and the kitchen range hood needs to be cleaned frequently. When the greasy dirt pollutes seriously, still can influence smoke ventilator's work efficiency, can influence smoke ventilator's life even. The existing range hood uses a fan as power to suck indoor oil smoke, smoke naturally passes through a blade and the fan in the range hood, fine oil droplet particles in the smoke can be adhered to the fan and the blade when passing through the fan along with air flow, oil stains are formed, the range hood is difficult to clean, and the using effect of the oil smoke can be influenced.
The shortcomings of the range hood in the prior art are as follows:
1. short service life
The range hood vibrates too much and is easy to leak oil. The assembly and the installation are not professional, foreign matters exist on the blades, the internal scale deposit is too thick, the motor bearing is abraded or the bearing hole is too large, the high-amplitude vibration of the range hood can be caused, and the service life is influenced.
2. Difficulty in cleaning
The cleaning of the range hood is always a headache which troubles users, and many range hoods are troublesome to disassemble and can be cleaned by professional cleaning personnel who need to go to the door, but the cleaning is not only expensive but also incomplete, and the cleaning times and the cost are increased.
3. Loud noise
The resistance of oil drop adhesion and gas flow is increased, the running noise of the exhaust fan is obviously increased, and kitchen workers are polluted by noise in busy kitchens.
SUMMERY OF THE UTILITY MODEL
To the defect that exists among the prior art, the utility model aims to provide an easily wash lampblack absorber has solved the problem of the not good clearance of the inside fan of traditional lampblack absorber. The oil smoke of the traditional range hood passes through the fan, so that the fan inside the traditional range hood can be polluted by oil after being used for a long time, the resistance of the fan is increased, the power consumption is increased, and the noise of the fan is increased; if the cleaning is carried out, the whole machine must be disassembled to carry out the cleaning, which is time-consuming and labor-consuming. The application provides a lampblack absorber utilizes annular air outlet's negative pressure to absorb the oil smoke, and the oil smoke can not pass through the fan, so avoided the fan can adhere to the condition of greasy dirt, solved the fan among the smoke ventilator easily be stained with the greasy dirt and difficult abluent difficult problem, improved smoke ventilator's clean degree and life again.
In order to achieve the above purpose, the utility model adopts the technical proposal that:
the utility model provides an easy washing lampblack absorber, from up including in proper order down: the smoke cover 2, the air duct bracket 3, the top cover 6 and the flue 5;
an air duct bracket 3 is arranged on the Longxu smoke hood 2, a top cover 6 is arranged above the air duct bracket 3, and a flue 5 is arranged above the top cover 6;
a supporting rib 8 is arranged inside the air duct bracket 3, and an annular air duct 7 is arranged on the supporting rib 8 in the air duct bracket 3; the two sides of the annular air duct 7 are provided with fans 4; the lower end of the flue 5 is tightly pressed on the annular air duct 7 and is fixed on the air duct bracket 3 by screws, so that excessive resonance caused by the flow of wind is avoided.
On the basis of the technical scheme, the ridging smoke cover 2 and the air duct bracket 3 are fixed through screws.
On the basis of the technical scheme, the front surface of the exhaust hood 2 is provided with a control panel 1 for realizing multifunctional control.
On the basis of the technical scheme, a start/pause key, an air speed increasing key, an air speed reducing key, a timing key, an illuminating lamp key and the like are arranged on the control panel 1.
On the basis of the technical scheme, the control plate 1 is fixed on the front surface of the Longfeng cover 2 through screws.
On the basis of the technical scheme, a sealing ring is arranged at the joint of the fan 4 and the annular air duct 7, and the air leakage is avoided by rotating and locking.
On the basis of the technical scheme, the flue 5 is of an inverted funnel shape with openings at the upper part and the lower part.
On the basis of the technical scheme, the top cover 6 is provided with an opening matched with the flue 5 and used for enabling the flue 5 to penetrate through.
On the basis of the technical scheme, the top cover 6 is fixed on the air duct bracket 3 through screws.
On the basis of the technical scheme, the supporting ribs 8 and the air duct support 3 are integrally formed and used for strengthening the strength of the air duct support 3 and supporting the annular air duct 7.
Traditional lampblack absorber is usually with the fan setting inside the wind channel, long-time back of using, and inside fan can adhere to a lot of oil smoke, influences the health and follows life, but inside fan normally can't oneself be abluent, must look for special professional team with equipment just can wash to the price is expensive.
The utility model discloses with the fan setting in the both sides of annular duct, because the fan is not in the cigarette passageway, the oil smoke not with fan direct contact, so solved the easy greasy dirt of being stained with of fan among the smoke ventilator and difficult abluent difficult problem, increase fan life that can be better. The utility model discloses based on the principle of "Kangda effect", the wind that makes to come out through the wind channel of optimizing increases the velocity of flow, drives the surrounding air and replenishes to utilize the negative pressure that produces to absorb the oil smoke, this annular duct that will require the fan to connect will do the design, because the air-out that just so can be better, just can bigger drive the bottom oil smoke, improved smoke ventilator's clean degree again.
