Problems solved by technology

Therefore, the existing range hood scheme that adopts the cyclone filter is relatively single
Moreover, the range hoods used by existing cyclone filters are mainly side suction range hoods, which limits the application space of cyclone filters in the range hood field to a certain extent.

Embodiment 1

[0030] A range hood embodiment proposed by the present application, such as Figure 4 As shown, the range hood is a top-suction range hood, which includes a cyclone filter, a support 5 , a smoke collection hood 6 , a fan and a casing 7 . The casing 7 is fixedly arranged above the smoke collecting hood 6 , and the fan is arranged in the casing 7 . The number of cyclone filters is two, and the structures of the two cyclone filters are the same. The two cyclone filters are plate-shaped, such as Figures 1 to 3 shown. The number of support members 5 is one. The support member 5 is placed on the range hood, specifically, the fume collecting hood 6 is provided with an air inlet, the support member 5 is placed on the edge of the air inlet, and the air inlet is spaced to form a left inlet and a right opening . Because it is set up, the user can easily remove the support 5 by lifting the support 5 upwards and adjusting a certain angle. The supporting member 5 placed on the range ...

Embodiment 2

[0039] The present application also proposes another embodiment 2 of the range hood, which is further improved on the basis of the above embodiment 1 of the range hood. The main differences between the second embodiment of the range hood and the first embodiment of the range hood are as follows.

[0040] The air inlets 2 of the two cyclone filters of this range hood embodiment 2 are also all set towards the outside of the range hood, as Figure 5 shown. One ends of the air intake pipes 1 of the two cyclone filters extend toward the same area, forming a recessed structure, which is recessed toward the inside of the range hood, so that the recessed structure forms a smoke cavity. Specifically, one end of the air inlet pipe 1 of the left cyclone filter and one end of the air inlet pipe 1 of the right cyclone filter all extend toward the same area, that is, one end of the air inlet pipe 1 of the left cyclone filter One end of the air intake pipe 1 and the right side cyclone filt...

Embodiment 3

[0043] The present application also proposes another embodiment 3 of the range hood, which is further improved on the basis of the above embodiment 1 of the range hood. The main differences between the third embodiment of the range hood and the first embodiment of the range hood are as follows.

[0044] Embodiment 3 of this range hood is a side suction type range hood, as Image 6 As shown, the smoke collecting hood 6 of the side suction range hood is provided with an inclined airflow inlet. The support member 5 is placed approximately obliquely (the inclination angle of the support member 5 is approximately the same as that of the air inlet), one end of the support member 5 extends upward, and the other end of the support member 5 extends downward, as Image 6 shown. In the third embodiment of the range hood, one end of the air intake duct 1 of the left cyclone filter and one end of the air intake duct 1 of the right cyclone filter both extend toward the support 5 placed ob...

Abstract

The application provides an improved range hood which comprises two cyclone filters; each cyclone filter comprises at least one air inlet pipeline (1); air outlets (3) of the air inlet pipelines (1) are formed in the end parts of the air inlet pipelines (1); air inlets (2) are formed in the side walls in the middle of the air inlet pipelines (1); baffles (4) are arranged between the air outlets (3) and the air inlets (2); the air inlets of the two cyclone filters face the outer part of the range hood; and one end of the air inlet pipeline (1) of each cyclone filter extends to a same area to form a convex structure or a concave structure. Through the adoption of the technical scheme, the lampblack exhausting and discharging efficiency is beneficially improved.

Description

【Technical field】 [0001] This application relates to the field of range hoods. 【Background technique】 [0002] At present, a range hood scheme using a cyclone filter has been proposed, such as the US patent number US4872892. In the existing solutions, the technical focus is mostly on the cyclone filter itself, which is relatively limited. Therefore, the existing range hood scheme that adopts the cyclone filter is relatively single. Moreover, the range hoods used in the existing cyclone filters are mainly side suction range hoods, which limits the application space of the cyclone filters in the range hood field to a certain extent. [0003] Unless supported by sufficient evidence, prior art described herein is not an admission that such prior art was known to those of ordinary skill in the art to which this application relates before the filing date of this application. 【Content of invention】 [0004] An object of the present application is to provide an improved range h...
