Circulation type dismounting and washing free cooking-fume exhauster

Abstract

The invention relates to an unpicking and washing-free recirculating range hood which comprises a lampblack absorbing part, a lampblack liquid dissolving circulating system and a case. A circulation loop comprises a grid plate and a water tank containing oxygen purification water solution, one end of an inlet tube is connected with the water tank, and the other end of the inlet tube is connected with a water pump, the water pump is sequentially connected with an outlet tube, a nozzle, a mixing chamber, a mixing tube, a diffusion tube, a tee pipe, a reducer, a straight tube and a return hose; one end of the return hose is arranged in the water tank, and a lampblack collecting hood is fixed on the mixing chamber. In the range hood, four components which are the nozzle, the mixing chamber, the mixing tube and the diffusion tube form a Venturi tube structure to generate a negative-pressure lampblack suction; which replaces the traditional suction methods in which a fan is driven by a motor; the oxygen purification water washing solution is employed to dissolve the lampblack which is circularly scoured in the tube, thus ensuring the tube wall to be free of oil stain, and realizing the free internal unpicking and washing of the range hood. The range hood does not need any mechanical rotating part when in operation, and has the advantages of no wear, low noise, reliable operation, safe use, low cost, simple maintenance and no environmental pollution, and no lampblack is directly discharged to the atmosphere.

Description

Technical field [0001] The invention relates to a circulation type range hood without disassembly and washing. It belongs to the field of exclusion of cooking fumes. Background technique [0002] There are two kinds of range hoods commonly used in the market now. One is the traditional range hood, that is, the exhaust fan. The motor drives the fan blades to rotate. The fan blades are curved, and the price is cheap. Noise pollution; the oil fume is directly discharged outside, and the oil on the wall and the ground piles up, which affects the appearance of the house and pollutes the environment; it is difficult to clean the oil, and the rotating blades and oil baffles of the range hood are heavily oiled. When cleaning, the exhaust fan needs to be removed, which is extremely difficult. trouble. The other is the second-generation range hood, the motor drives the blades to rotate, and the blades are flat, which are divided into European range hoods and side suction range hoods...

[0002] There are two kinds of range hoods commonly used in the market now. One is the traditional range hood, that is, the exhaust fan. The motor drives the fan blades to rotate. The fan blades are curved, and the price is cheap. Noise pollution; the oil fume is directly discharged outside, and the oil on the wall and the ground piles up, which affects the appearance of the house and pollutes the environment; it is difficult to clean the oil, and the rotating blades and oil baffles of the range hood are heavily oiled. When cleaning, the exhaust fan needs to be removed, which is extremely difficult. trouble

The other is the second-generation range hood, the motor drives the blades to rotate, and the blades are flat, which are divided into European range hoods and side suction range hoods. The disadvantage is that most of the oil fumes are still directly discharged into the air. Cause environmental pollution; the rest of the fume stays inside the machine, contaminates the inner wall of the hood, causes a large amount of uneven oil accumulation on the fan impeller, the fan loses dynamic balance, the suction effect is getting worse, and the mechanical noise is getting louder; it is difficult to clean , a large amount of oil accumulates in the fan blades and the inner cavity of the machine, which generally requires professional cleaning or additional equipment, which consumes a lot of energy; in order to ensure the short-term suction effect, the power of the range hood is generally high (200W ~ 250W); there is no effective The purification function makes the efficiency of traditional hoods drop rapidly

As the use time increases, the filter screen will accumulate oil, and the oil absorption effect will become significantly worse, resulting in a lot of noise

At present, there is also a range hood with an automatic cleaning device on the market. This series of automatic hoods adopts automatic high-pressure rotary spray technology, and a cleaning pump is added to clean the kettle, automatic control chip, catheter and other related equipment. The principle is similar to the principle of high-pressure spray gun car washing; this series of automatic range hood washing machines has complex structure, high energy consumption, and high price. The price ranges from 3000 to 5000 yuan. The inside of the hood is clean
