Title:
RANGE HOOD HAVING GOOD FILTERING EFFECT AND CLEANING DEVICE FOR RANGE HOOD
Document Type and Number:
WIPO Patent Application WO/2023/133663
Kind Code:
A1
Abstract:
A range hood having a good filtering effect and a cleaning device for the range hood. A filtering device comprising a plurality of filtering assemblies is mounted in a range hood body (1), so that after oil fume is sucked in, the oil fume can enter a filtering box (31) through an oil fume intake pipe (32), and the oil fume is filtered by means of a filtrate or a solid filtering medium in the filtering box (31) and then discharged from a ventilation duct (12), thereby effectively improving an oil fume filtering effect, reducing the oil fume attached to a distal end of the filtering device in the range hood, guaranteeing a stable working efficiency of an air suction system, and allowing few fume pollutants and particles to be discharged; in addition, the cleaning device is connected to one side of the range hood body (1), so that the cleaning device rotatably covers the bottom of the range hood body (1), and thus the position of the bottom of the range hood body (1) which makes direct contact with the oil fume can be embedded in a cleaning cavity (81) and cleaned by means of ultrasonic waves or high temperature to remove oil stains attached to the range hood body (1), thereby facilitating cleaning, achieving a good cleaning effect and high efficiency, and reducing manual participation.
