Embodiment Construction

[0017] See attached figure 1 To attach Image 6 , a range hood 1, comprising, a housing 2, the housing is composed of two parts, a chimney part and a fume collecting part. A control panel 4 for controlling the range hood and an illuminating lamp 8 for providing illumination when needed are arranged at the oil fume collecting part. The housing has a lower rear part 17 and a hood contact surface 18 with the fume inlet 3 . An airflow generating unit (not shown in the drawings) is accommodated in the casing. A grease filter device 6 covers the oil fume inlet 3. When working, the airflow generating unit operates to generate an operating airflow, and the oil fume containing oil, fat and water generated during the cooking process enters the range hood through the grease filter device 6, most of which are contained in the The oil, grease and water in the oil fume are filtered and removed by the grease filtering device 6 and transported to the rear part 17 of the casing. A screw ho...

Abstract

The invention relates to a range hood, which comprises an oil / fat filtering device provided with a through hole, and a shell provided with a lampblack inlet, wherein a position, corresponding to the position of the through hole on the oil / fat filtering device, on the shell is provided with a screw hole. The range hood is characterized by further comprising a fixing assembly which mainly comprisesa screw and a position limiting component, wherein the screw is provided with a first stud part of which the length is L1 and the diameter is D1 and a second stud part of which the length is L2 and the diameter is D2; the diameter D2 is longer than the diameter D1, and a shaft shoulder is formed at the joint of the first stud part and the second stud part; when the second stud part is positioned in the through hole and the position limiting component is connected to the first stud part by pressing against the shaft shoulder, the fixing assembly is movably limited in the through hole formed onthe oil / fat filtering device; and the oil / fat filtering device is screwed into the screw hole through the first stud part and is covered at the lampblack inlet. The range hood avoids the inconveniences caused by easy dropping of bolts in the operation processes of connecting and fixing the oil / fat filtering device.

Description

technical field [0001] The invention relates to a range hood, in particular to a range hood for household or restaurant use. Background technique [0002] The oil filters of existing range hoods on the market are basically fixed to the housing of the range hood by screws. Because ordinary standard screws are used, when the oil filter of the range hood needs to be installed on the range hood or the oil filter needs to be removed from it, the operator often needs to hold the screw, Screwdriver and oil filter, but also need to do the corresponding operation. Because there are too many things in the operator's hands at the same time, the phenomenon of screw falling often occurs. Therefore, the structure and parts involved in the loading and unloading of the oil filter screen of the existing range hood are very inconvenient and need to be improved. Contents of the invention [0003] The present invention aims at the above problems in the prior art, and provides a screw part ...
