Description

technical field [0001] The invention relates to a pipeline type range hood. Background technique [0002] Cooking fume is the fume produced after cooking oil and food are heated at high temperature, and it widely exists in the kitchens of households and catering industries. In recent years, with the improvement of people's living standards and the development of the catering industry, the consumption of cooking oil has been increasing, and cooking fume has become one of the main pollutants of indoor air pollution. Jilin University recently completed a "Study on the Health Hazards of Cooking Oil Fume", which shows that cooking oil fume contains a variety of toxic chemical components, which have lung toxicity, immunotoxicity, genotoxicity and potential carcinogenicity to the body. People who have been in contact with cooking fume for a long time will have a series of symptoms, which are collectively referred to as "kitchen fume syndrome", which is comm...

AI Technical Summary

Problems solved by technology

Due to the open structure of the air guide hood, under the disturbance of the rising oil fume by the horizontal air flow, the effect of oil fume collection and discharge is not satisfactory, and a part of the oil fume will still be diffused in the room, floating and dripping on the walls, ceiling, ground and other On the items, the oil fume will also adhere to the air guide hood and exhaust channel, and drip onto the stove, causing indoor pollution and hindering cleaning

In order to enhance the effect of oil fume exhaust, fans with large wind pressure and large air volume are often used, but this will increase the power of the fan and increase the noise, and its effect of enhancing oil fume exhaust is limited

Moreover, many common range hoods do not have the function of purifying oil fume, or although they have the function of purifying oil fume, the purification effect is not good, and the pollutants in the oil fume cannot be effectively recovered and processed centrally, causing secondary pollution to the outdoor environment

[0004] Chinese Patent Publication No. CN2295146Y, the publication date is October 21, 1998, the name of the invention is "a range hood" discloses a range hood, the range hood mainly includes a cylindrical shell, a chassis, an exhaust fan , oil drain hole, air guide cover, switch plate, oil collecting cup, air inlet, air outlet and the degreasing net made of PTFE film electret material with small holes, its shortcomings Yes: The air guide hood is an open structure, which is the same as the common range hood air guide, and the oil fume exhaust effect is not good, which will cause indoor pollution; although the film degreasing net has a good degreasing effect, it needs to be replaced frequently

[0005] Chinese Patent Publication No. CN1515833A, the publication date is July 28, 2004, the name of the invention is "fully enclosed kitchen range hood", which discloses a fully enclosed range hood, which mainly includes a suction fan , oil fume exhaust pipe, stove shield, air inlet, air bag sleeve, material box with closed door, observation window, door, shelf for spatula bowl cover, its disadvantages are: although the fully enclosed structure can Exhaust most of the oil fume outside, but it has no function of purifying the oil fume. The pollutants in the oil fume cannot be effectively recovered and processed centrally, causing secondary pollution to the outdoor environment; the existence of the airbag sleeve makes it inconvenient to operate during cooking, which is different from the traditional Cooking habits are inconsistent, and the procedures for removing and preventing materials are complicated; the inside of the range hood with a fully enclosed structure is easy to be stained with oily smoke, and it is difficult to clean

[0006] Therefore, the existing products have the following deficiencies: they cannot achieve a good effect of removing oil fume on the basis of maintaining the traditional cooking operation habits, and it is inconvenient to clean
