Example one

This embodiment provides a domestic smoke ventilator of non-maintaining, as shown in figure 1, including lampblack absorber body 1, smoke deflector 2, oil cleaner screen 3 and greasy dirt cleaning device 5. In smoke collecting hood 101 of lampblack absorber body 1 was located to smoke deflector 2 liftable, the lampblack absorber of this kind of smoke deflector liftable was used mechanically for the directness of current lampblack absorber, and its structure is prior art, does not do here and gives unnecessary details. In oil cleaner 3 located the collection smoke chamber 102 of lampblack absorber body 1, oil cleaner adopted multilayer structure's oil cleaner, as shown in figure 1, the oil cleaner of this embodiment adopts upright quadrangular frustum of pyramid form mounting structure. Connect oil groove 4 detachably to install around oil filter screen 3, the oil groove that connects all around is linked together, and the fluid that filters off from the oil filter screen can flow into and connect the oil groove to store, connect oil groove 4 preferred to be made with transparent material, be convenient for observe the oil mass in the oil groove that connects. In order to solve the problem that the existing range hood needs to be disassembled to clean oil stains, the oil stain cleaning device is arranged on the smoke guide plate in the embodiment, the oil stain cleaning device 5 is arranged on the smoke guide plate 2 and can be accommodated in the smoke collection cavity 102, as shown in the attached drawing 1, after the smoke guide plate closes the smoke collection cavity, the oil stain cleaning device is accommodated in the smoke collection cavity without interfering with the closing of the smoke guide plate. Preferably, a sealing strip is arranged in the smoke collection cavity, and the smoke guide plate is sealed through the sealing strip after being closed.

Preferably, the oil stain cleaning device 5 of this embodiment includes the casing 501 and locates air heater 502 and ozone generator 503 in the casing, the top of casing 501 is equipped with the air exit, and the air intake is located the bottom of casing 501, and the air intake runs through smoke deflector 2 to set up electronic air door 504 at the air intake.

This embodiment is when the greasy dirt that needs to clear up: closing the smoke guide plate, opening the oil stain cleaning device and the smoke exhaust ventilator, generating hot air by the air heater (at the moment, the electric air door is opened, cold air enters the air inlet, and hot air exits the air outlet), simultaneously preparing ozone gas by the ozone generator, enabling the ozone gas to enter the smoke exhaust ventilator under the suction force of the smoke exhaust ventilator, and carrying out oil dissolving and sterilization treatment on the inner wall of the smoke exhaust ventilator and the fan, so that the oil stuck in the smoke exhaust ventilator is softened and flows into the oil receiving groove. The utilization of the ozone in the embodiment can decompose oil macromolecular substances on the one hand, is convenient for oil flowing fluency, reduces oil viscosity, and on the other hand can sterilize and eliminate harm to health.

It is worth mentioning that: the temperature of the hot air generated by the hot air blower is set to be adjustable, the adjustable temperature range is set according to the temperature-viscosity characteristic curve of the oil, the temperature rise is controlled below the flash point of the oil, the situation that the temperature rise is too high to reach the flash point of the oil is avoided, and the safety is guaranteed.
