range hood

Abstract

The invention discloses a smoke exhaust which comprises a rack assembly (3) internally provided with a fan (6) and further comprises an electrostatic device (2). A check valve (7) is arranged at the end of the rack assembly to be connected with a smoke exhaust pipe, and the electrostatic device is detachably connected between the check valve and the smoke exhaust pipe (1). The electrostatic deviceof the smoke exhaust is mounted between the check valve and the smoke exhaust pipe which are arranged at an air outlet of the smoke exhaust and not designed inside the smoke exhaust, thus when the electrostatic device is disassembled and assembled, cumbersome operation such as pre-disassembly-and-assembly of a shell of the rack assembly of the smoke exhaust does not need to be conducted, and theelectrostatic device can be directly disassembled and assembled, so that operation is more convenient and quicker; meanwhile, before smoke enters the electrostatic device, part of the smoke is adsorbed, only part of the smoke flows to the electrostatic device at the rear end, and thus the service life of the electrostatic device can be prolonged; and in addition, in the process that the electrostatic device is disassembled for cleaning, the smoke exhaust pipe can be directly mounted on the check valve, so that normal use of the smoke exhaust is not affected.

Description

technical field [0001] The invention relates to the field of household kitchen appliances, in particular to a range hood. Background technique [0002] With the increasing awareness of environmental protection, air pollution has become a hot topic among people. During the cooking process, a large amount of harmful substances are produced along with the burning of oil fume and fuel. Some traditional range hoods directly exhaust the oil fume to the outside, causing the oil fume to directly enter the atmosphere and cause air pollution, which affects people's health. [0003] In view of the above-mentioned problem of oil fume polluting the atmosphere, more and more range hoods are currently using electrostatic oil filtering methods to purify the oil fumes. The method has gained certain approval in terms of application. However, due to long-term use, the electrostatic device of the range hood will accumulate a large amount of grease, which will reduce the performance and smoki...

AI Technical Summary

Problems solved by technology

However, due to long-term use, the electrostatic device of the range hood will accumulate a large amount of grease, which will reduce the performance and smoking effect of the electrostatic device. Therefore, it needs to be disassembled and cleaned after pollution to restore the good performance of the electrostatic device to absorb oil fume.

Usually, the electrostatic device is installed inside the range hood, and when disassembling the electrostatic device, it is necessary to disassemble the housing of the frame assembly of the range hood. The electrostatic device is inconvenient to disassemble and clean, and it is difficult to achieve the effect of circulating oil filtration
