Ultrasonic no-clean kitchen ventilator without pipe and cooking fume filtering and removal method

Abstract

The invention belongs to the technical field of kitchen appliances and provides an ultrasonic no-clean kitchen ventilator without a pipe. The kitchen ventilator includes a housing 1, a cooking fume filtering device 6, a cooking fume cleaning device 5, a draught fan 2 and the like. An air suction port 3 and a vent port 4 are formed in the housing 1, and when the draught fan 2 is started, cooking fume is sucked in from an air inlet 12, filtered by the cooking fume filtering device 6 and then discharged from the vent port 4. The housing 1 also internally includes the cooking fume cleaning device5 sleeving the cooking fume filtering device 6, and the function of automatically cleaning away the filtered cooking fume can be achieved to maintain the cleanness and cooking fume filtering efficiency of the cooking fume filtering device 6. The invention also provides a cooking fume filtering and removal method adopting the ultrasonic no-clean kitchen ventilator without a pipe, the cooking fume is directly filtered and removed, clean air is discharged, the installation, construction and maintenance costs of traditional kitchen ventilators and pipes are omitted, environmental pollution is notcaused, and the problem of manual cleaning is avoided.

Description

technical field [0001] The invention belongs to the technical field of kitchen appliances, in particular to a range hood with a self-cleaning function and a use method thereof. Background technique [0002] Existing kitchen treatment methods for oil fume exhaust gas mainly rely on range hoods for suction and discharge. Existing range hoods are generally fixedly installed above or on the side with a certain distance from the source of fuel fume and exhaust gas, and then the pumped oil fume exhaust gas is discharged. It is discharged to the outside through pipes, and it does not effectively filter the oil fume, but only discharges the oil fume from the indoor to the outdoors, which is very unenvironmental. [0003] Even if some range hoods are equipped with a coarse filter screen, the oil will adhere to the filter screen and various parts inside the range hood after long-term use, which is not only inconvenient to clean, but also reduces the suction function of the range hood,...

AI Technical Summary

Problems solved by technology

[0003] Even if some range hoods are equipped with a coarse filter, oil stains will adhere to the filter screen and various parts inside the range hood after long-term use, which is not only inconvenient to clean, but also reduces the suction function of the range hood, making it impossible to draw well. The exhaust gas from oil suction reduces the air quality in the kitchen when cooking

[0004] Because of the exhaust method of traditional range hoods, whether it is a range hood for household or restaurant use, it is necessary to install exhaust pipes, or even outdoor public smoke exhaust pipes. These exhaust pipes, especially the public exhaust pipes of buildings, if long-term The accumulation of oil pollution will cause great fire hazards, so professional cleaning and maintenance are required on a regular basis. The process is complicated, time-consuming and laborious, and the maintenance cost is very high.
