Problems solved by technology

[0009] The first category, filters based on synthetic fiber mats with a thickness of 10-20 mm, are less costly, but have the following disadvantages: low to medium head loss, low to medium efficiency not exceeding 50%, infrequent or faulty maintenance In the case of high fire hazards due to excess fatty acids retained, long and particularly careful manual cleaning is required, the duration is limited to a few months, repurchases are required at not insignificant periodic costs, and installation operations are cumbersome
[0020] Also, while these filters have an aesthetic consistent with those made of stainless steel, due to their few large ribs, these filters are very large and heavy, a fact that prevents them from being slim, modern appliances

Embodiment Construction

[0031] Referring to the above-mentioned drawings, the labyrinth type degreasing filter for the exhaust hood of the present invention is indicated by reference numeral 10 as a whole.

[0032] The degreasing filter 10 comprises an upper housing 11 and a lower housing 12 , which are installed in cooperation with each other and have a plurality of transverse grooves 13 , 14 .

[0033] Said shells 11 and 12 enclose between them a central partition unit 15 having a plurality of transverse openings 16 and a plurality of contact points with the upper shell 11 and the lower shell 12 .

[0034] These contact points are formed by a plurality of tips 17 and 18 pointing in opposite directions in groups.

[0035] As described in more detail below, said transverse openings 16 are offset relative to the transverse grooves 13 and 14 so as to form at least 4 deviations for the air flow in the space enclosed by the housings 11 and 12 .

[0036] The transverse grooves 13 and 14 belonging to the ...

Abstract

The invention discloses a degrease filter (10) which is used to taking out gas hood, its character includes: it has epitheca (11) and hypovalve (12), which have a lot of transverse grooves ( 13,14), the tracts ( 11,12) surround a isolating element (15), which has a lot of transverse uncorks (16) and a lot of contact points, and the transverse uncorks are excursion compared to the transverse grooves, so there at least four air flowing excursions which are surrounded by two tracts.

Description

technical field [0001] The invention relates to a labyrinth oil removal filter for an extraction hood. Background technique [0002] In particular, the present invention relates to the filtration of grease particles suspended in the airflow of ventilation units placed in kitchen hoods for the following reasons. [0003] Firstly, because the filtration keeps the interior of the extraction hood cleaner, grease deposits are avoided, which in certain circumstances could constitute a fire hazard, and secondly, because the filtration significantly minimizes the necessity for regular maintenance and cleaning operations. [0004] By avoiding the highly corrosive and decomposing attack of fatty acids, this filtration of grease particles prolongs the life of the internal components of the hood, such as motors, wiring, switches, lamp holders, lamps and rubber or plastic components. [0005] Optimal use of activated carbon-based hoods with odor suppression and internal recirculation is...
