Problems solved by technology

[0004] In the oil fume filtering device mentioned above, the two filter plates are simply bent and staggered to form a turning air flow channel. After the oil fume enters the air flow channel from the air inlet, it only needs two simple directions to flow out from the air outlet. , the number of times that the oil fume changes direction in the airflow channel is small, that is, the number of collisions between the oil fume and the filter plate is small, so the filter plate cannot better condense the oil fume as expected, and a large part of the particles in the oil fume still follow The flue gas is discharged from the airflow channel, adsorbed in the air duct of the range hood or discharged into the external environment, causing corrosion to the air duct of the range hood or adverse effects on the environment

Embodiment 2

[0031] see image 3 , in this embodiment, the first oil filter unit 23' and the second oil filter unit 24' have different structures, wherein the first oil filter unit 23' is roughly cross-shaped, including a vertically extending first pole 231', a first horizontal bar 232' extending transversely and vertically crossing the first vertical bar 231', the two ends of the first horizontal bar 232' are respectively bent downward to form a vertically extending first protruding part 233', the first A horizontal bar 232' is symmetrical to the crossing point of the first vertical bar 231', the top of the first vertical bar 231' extends laterally to both sides respectively, and the first horizontal bar 232' is located below the first horizontal bar 232' The part of the first vertical bar 231' together constitutes the first space 234', and the first horizontal bar 232' and the part of the first vertical bar 231' located above the first horizontal bar 232' jointly form the second space 23...

Embodiment 3

[0035] see Figure 4, in this embodiment, the first oil filtering unit 23" and the second oil filtering unit 24" have different structures, wherein the first oil filtering unit 23" is the same as the first oil filtering unit 23' in the second embodiment above The difference is that the first protruding portion 233" extends upwards and downwards at the end of the first cross bar 232", and is similar to the second vertical bar 241 of the second oil filter unit 24" as in the first embodiment. The "opposite side has a first protrusion 236", while the side of the second pole 241" has a second protrusion 246", the above two protrusions can increase the contact area with the oil fume, thereby improving the filtering effect. The first curved portion 243" of the second oil filter unit 24" is curved and extended to both sides at the top of the second vertical rod 241' to form an upwardly concave arc.

[0036] Same as in the second embodiment, the first cross bar 232 ″ and the first upr...

Embodiment 4

[0039] see Figure 5 , in this embodiment, the first oil filtering unit 23"' and the second oil filtering unit 24"' have different structures, wherein the first oil filtering unit 23"' is the same as the first oil filtering unit in the third embodiment above The difference of the unit 23" is that the first oil filter unit 23"' is king-shaped, the bottom end of the first vertical rod 231"' extends laterally to both sides, and the surface facing the second oil filter unit 24"' is The top of the first vertical rod 231"' extends laterally to both sides, and the surface facing the second oil filter unit 24"' is concavely curved and extended to form a king shape. Another horizontal part. The gap between the bottom ends of the two vertical rods of the two oil filter units is used as the air inlet 25"' of the air flow channel formed by the oil filter plate of the oil fume filter device, and the gap between the top ends of the two vertical rods The gap is used as the air outlet 26"' o...

Description

technical field [0001] The invention relates to a filtering device, in particular to a cooking fume filtering device for a range hood. Background technique [0002] Along with the improvement of living standard, the raising of the requirement of quality of life, range hood is used widely in each family as the important electric appliance that sucks the lampblack that produces when cooking in the family kitchen. The main problem at present is that when the range hood is working, the oil fume passing through the air duct tends to accumulate a large amount of oil in the air duct. Due to the high viscosity of the formed oil, it is difficult to discharge from the air outlet of the air duct, causing oil pollution to the pipeline. The corrosion of the range hood reduces the service life of the range hood and increases the use and maintenance costs of the range hood, while the other part is directly discharged. The range hood contains a large number of carcinogens and substances wit...
