Abstract

The invention discloses an air supply self-exhaust household kitchen ventilator. The air supply self-exhaust household kitchen ventilator comprises an air blowing device, a smoke extraction device and a smoke collecting hood device; the smoke extraction device is composed of an air blowing channel, a smoke extraction channel and a smoke inlet channel, wherein the air blowing channel and the smoke extraction channel are arranged horizontally, and the smoke inlet channel with a connection angle is vertically arranged; a smoke inlet is located in the bottommost end of the smoke inlet channel, and a smoke collecting hood is arranged at the smoke inlet; one end of the smoke extraction channel is connected to the air blowing device, and the other end of the smoke extraction channel penetrates through a wall and extends out of the wall; and the air blowing device is composed of an air blowing channel, a control interface and an air blowing motor. According to the novel air supply self-exhaust household kitchen ventilator, airflow is generated by the air blowing device blowing air to the smoke extraction channel through the air blowing channel, and then updraft generated in the smoke inlet channel drives oily fume to rise and is exhausted out of the wall along the smoke extraction channel. Due to the fact that the oily fume does not pass through the motor and a wind wheel in the exhausting process of the oily fume, the motor and the wind wheel cannot be contaminated by greasy dirt, the long-term application performance of the air blowing device is guaranteed, and the service life is prolonged. The novel air supply self-exhaust household kitchen ventilator is smooth in design structure, and noise in the working process is reduced dramatically. The split-type structural design is beneficial for later washing and maintenance.

Description

technical field

[0001] The invention belongs to the field of range hoods, and in particular relates to an air-supply self-extraction type household range hood. Background technique

[0002] At present, household range hoods all use smoking machines. When the oil fume passes through the motor wind wheel, the oil pollution is easy to stick to the wind wheel, thus reducing the smoking efficiency of the wind wheel. After long-term use, it is difficult to clean up after the accumulation of oil in the machine cavity, motor, and motor wind wheel. Because the motor is in a closed air intake channel, it will generate a lot of noise during operation. To sum up, I have designed a self-extracting air supply range hood for household use. Contents of the invention

[0003] In order to solve the above existing problems, the present invention provides a self-extracting air supply type household range hood.

[0004] The present invention is realized through the following technical solut...
