Household kitchen fume purifying method and range hood

Abstract

The invention provides a household kitchen fume purifying method and a range hood, belonging to the field of household appliances, wherein the method and range hood provided by the invention are used for solving the problem that kitchen fume pollutes the environment. In the range hood, a water curtain is arranged on a fume channel; water forming the water curtain is a purifying solution added with an oil dissolving agent; when fume passes through the water curtain in suction of the range hood, oil mist in the fume is sufficiently contacted with the purifying solution, so that the oil mist is completely dissolved in the purifying solution, and the purified fume is emitted outdoors through a fan; a fume purification chamber is arranged behind the frame of the range hood, and an inclined fume isolation plate is arranged in the middle of the fume purification chamber; a purifying solution nozzle is arranged above the fume isolation plate, the air inlet of the fan is arranged under the fume isolation plate, and a water curtain nozzle is arranged at the end part of the lower end of the fume isolation plate; a purifying solution tank is arranged on the lower part of the fume purification chamber; a circulating water pump is connected with the purifying solution tank; and a water outlet is connected with the purifying solution nozzle and the water curtain nozzle. The range hood has the characteristics of simple structure, practicability, convenience, high purification efficiency, energy conservation and environmental friendliness, and is suitable for purification and emission of fume for household kitchens.

Description

technical field

[0001] The invention belongs to the field of household electrical appliances, and mainly relates to a domestic kitchen fume purification method and a range hood capable of purifying and discharging the cooking fume generated in the domestic kitchen. Background technique

[0002] The range hood used at home is a household appliance that discharges the oily fume produced in the home kitchen to the outside, mainly through the suction of the fan to discharge the oily fume to the outside. During this process, part of the oil droplets in the oil fume are adsorbed to the air net, which reduces the oil content in the flue gas and partially purifies the discharged flue gas. The oil adsorbed on the wind net flows into the oil storage box, and its cleaning is also very troublesome. Since the mesh of the wind net cannot be very small, the proportion of the area occupied by the mesh or mesh plate that absorbs oil fume cannot be very large, otherwise the increase in resis...
