Harmless discharge range hood

Abstract

The invention discloses a harmless discharge range hood. The problems that in the prior art, oil fume dirt is liable to adhere to the inner walls of oil fume separation pipes, then the waste discharging efficiency is lowered, oil fume mixtures coagulate on oil fume suction hoods, cleaning is troublesome, and discharged waste gas contains fume and pollutes the atmosphere environment are solved. Theharmless discharge range hood comprises an oil fume suction hood body, an oil fume separation box body, a waste gas discharging device, a flange, a microprocessor, an audible and visual alarm, a smoke concentration sensor, a flange oil collection groove, an oil fume extraction pipe, an oil fume separation pipe, a negative pressure fan, an oil fume separation fan, an electric push rod, an oil pushing tool, a separation pipe oil collection groove, a waste oil collection box, a first waste gas discharging pipe, a purification pool, a second waste gas discharging pipe, a purification pool cover,a water inlet and outlet pipe and a water inlet and outlet electromagnetic valve. Oil fume dirt on the inner wall of the oil fume separation pipe can be effectively removed, little oil fume mixtures coagulated on the bottom face of the oil fume suction hood can be collected, the operation intensity of users is relieved, meanwhile, discharged waste gas can be completely purified, and waste gas harmless discharging is achieved.

Description

technical field [0001] The invention relates to a range hood with harmless discharge. Background technique [0002] The range hood is a kitchen appliance that purifies the kitchen environment. It is installed above or on the side of the kitchen stove. It can quickly suck away the waste burned by the stove and the harmful oil fume generated during the cooking process, and discharge it outdoors to reduce pollution. Existing range hoods generally have a waste oil collection tank in the oil fume separation box, and an oil collection cup is connected to the bottom of the waste oil collection tank. It flows into the waste oil collection tank, and finally enters the oil collection cup to be disposed of, but the inner wall of the oil fume separation box is easy to adhere to a thick layer of oil fume after years of use, which will increase the oil fume in the oil fume separation box to pass through the oil fume Separate the resistivity of the cabinet, which will reduce the working e...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: to provide a range hood with harmless discharge, which solves the problem that the oil fume separation tube in the prior art is easy to adhere to the oil fume dirt, thereby reducing the efficiency of the range fume, and the bottom surface of the range hood will condense a small amount of oil fume mixture and drop to the bottom of the range hood. The kitchen stove brings cleaning troubles, and the exhaust gas contains smoke and pollutes the atmospheric environment
