Problems solved by technology

This creates some problems: the exhaust pipe must be connected to the fan outlet with screws or clips
This leads to slow progress, difficult to intervene problems, but also increases the cost of the user

Embodiment Construction

[0028] Refer to figure 1 , The figure shows a household or industrial exhaust hood, which is equipped with a quick-fixing component for centrifugal fan according to the present invention, wherein the exhaust hood is denoted by reference numeral 11.

[0029] The exhaust hood for domestic or industrial use is provided with a smoke or vapor collection structure 12 which is wider at the bottom and tapered toward an upper opening 13 at the top. The exhaust hood 12 is provided with a centered and fixed flange 14 of the upper outlet end 15 of the centrifugal fan 16 at the upper opening 13.

[0030] The flange 14 is provided with an upper tubular extension portion 17, in which a lower terminal (not shown) of an exhaust pipe or exhaust pipe is installed and connected, and the exhaust pipe or exhaust pipe points toward the exhaust pipe where the exhaust pipe is installed. The outside of the hood's environment. The lower terminal of the exhaust pipe or the exhaust pipe is fixed in a standar...

Abstract

A domestic or industrial hood having a rapid attachment device for a centrifugal fan wherein an opening (13) is foreseen in the structure (12) of the hood being externally connectable to a discharge hose and adapted to receive one end (17) of a centrifugal fan (16), and wherein the opening (13) in said hood is equipped with a flange (14) for centring and housing the upper exit end (17) of the centrifugal fan (16) and also including at least one easily removable centring and attachment element (19) from a lower portion (20) of the fan (16) on the hood structure.

Description

Technical field [0001] The invention relates to a household or industrial fume exhaust hood provided with a quick-connecting component for a centrifugal fan. Background technique [0002] In household and / or industrial fume hoods, centrifugal fans discharge a certain amount of air flow from the inside of the enclosed environment to the outside. This can be accomplished by using a suitable suction duct. The suction duct extracts air from an environment full of grease vapor, dust, humidity and various organic particles, and transports the extracted air to the surface, thereby generating an impact, and then extracting it. The air continues to slide to precipitate multiple layers of solid particles through speed loss or adsorption. Among the grease vapor, grease particles of various sizes are dispersed in the air in a microscopic form, and organic particles include highly polluting mixtures. Therefore, it is very important to clean the air duct periodically and frequently to maintain...
