Problems solved by technology

The existing household range hood equipment can basically only remove large particles of oil droplets in the lampblack, while the small particles that are more harmful to the human body are directly discharged into the atmosphere, making the fragile atmospheric environment worse. Oil fume purification equipment mostly adopts filtration, electrostatic adsorption and other means. Although effective, the cost is high and the price is expensive, so it cannot be popularized in ordinary families.

Embodiment Construction

[0027] The present invention will be further explained below in conjunction with the drawings:

[0028] See figure 1 , The exhaust pipe of the range hood main body 1 is connected to the two-stage series-connected oil fume purifiers 3, 4, separator 7 and flue 8 in sequence via a connecting pipe 2 equipped with a check valve. The oil fume purifier 3 , 4 is equipped with purification liquid, the flue gas inlet of the oil fume purifier 3, 4 is lower than the purification liquid level to improve the mixing efficiency of the oil fume and the purification liquid, and the flue gas outlet is higher than the purification liquid level to promote the purification The flue gas is quickly discharged; at the height of the purified liquid level of the oil fume purifiers 3 and 4, there are agitators 3.1, 4.1 with a stirring speed of not less than 2000 rpm, and the blades of the agitators 3.1, 4.1 are external The tip is a triangular blade; the oil fume purifiers 3, 4 are equipped with heaters 3.4...

Abstract

The invention relates to a domestic environment-friendly extractor hood solving the problems that an existing extractor hood is poor in cooking fume removing effect, complex in structure and high in cost. According to the technical scheme, the extractor hood comprises an extractor hood body and a flue. An exhaust pipe of the extractor hood body is connected with the flue through a cooking fume purifier and a separator. A stirrer is arranged at the purification liquid level height of the cooking fume purifier. A top liquid inlet of the cooking fume purifier is connected with a purification liquid storage tank. A bottom liquid outlet of the cooking fume purifier is connected with a waste liquid collecting tank. The domestic environment-friendly extractor hood is simple in structure, good in cooking fume purification effect and convenient to use and install, and the existing extractor hood can be simply improved.

Description

Technical field [0001] The invention relates to an absorption hood, in particular to a household environmental protection range hood. Background technique [0002] During cooking, when the temperature reaches 170°C, the smoking point of edible oil, the oil will decompose to produce oily smoke, accompanied by a pungent smell. The oily smoke contains many harmful substances including acrolein, benzene, and formaldehyde. The oil fume material of 0.01 micron-0.3 micron is adsorbed on the atmospheric dust and suspended in the air for a long time, which will cause great harm to human health. Since most of the dishes in the Chinese diet are made in the way of "frying, frying, simmering, and stir-frying", the amount of oil fume is extremely large. According to reports, oil fume pollution has accounted for about 10% of PM2.5, and its harmful substances The content is much higher than car exhaust. The existing household range hood equipment basically can only remove the large particles o...
