Description
Technical field
The utility model is related to kitchen ventilator Parts manufacturing technology fields, are specially a kind of outlet housing for reducing noise.
Background technology
Typically common flue used in the building of household resident now, the range hood discharge of every household
Oil smoke from range hood enter common flue after above house discharge, if air outlet for kitchen ventilator is poorly sealed, will lead
The oil smoke of underlying User is caused to enter the room of upper strata resident family in discharge process or when blowing hard or air pressure is low, can also be gone out
The exhaust outlet of oil smoke from the range hood of resident family of lower floor of existing upper strata resident family discharge enters the situation in house, generates between air flue
Collaborate mutually, smoke blowing the phenomenon that.So general kitchen ventilator sets outlet housing all at the air outlet of kitchen ventilator, set in outlet housing
Put valve block, valve block usually kitchen ventilator using when open oil smoke being expelled to common flue.
But oil stain of the outlet housing after long-term use in oil smoke can be adsorbed on the surface of discharge pipe, not easy cleaning, it is impossible to
Enough that oil smoke is filtered, kitchen ventilator can generate noise at work, and exhaust effect is bad, therefore we make this and change
Into a kind of outlet housing for reducing noise of proposition.
Utility model content
The table in discharge pipe can be adsorbed for the oil stain in solution outlet housing existing in the prior art after long-term use oil smoke
Face, not easy cleaning, it is impossible to which the defects of being filtered to oil smoke, the utility model provide a kind of outlet housing for reducing noise.
In order to solve the above-mentioned technical problem, the utility model provides following technical solution：
The utility model it is a kind of reduce noise outlet housing, including kitchen ventilator and cover body, the air outlet of the kitchen ventilator with
The threaded hole that air inlet plate surface is equipped with is bolted to connection, and the opposite side of the air intake plate and one end of cover body are fixed and connected
It connects, the inside of the cover body is fixed with filter screen, and the other end of the cover body is equipped with discharge pipe, on the inner wall of the discharge pipe
Equipped with noise reduction layer.
Further, the cover body is obliquely installed.
Further, one end of the discharge pipe is equipped with check (non-return) valve.
Further, the noise reduction layer includes dampening foams, and the outer wall of dampening foams is equipped with noise reduction rubber wall.
Further, the other end of the cover body is fixedly connected by connecting flange with one end of discharge pipe.
Compared with prior art, the utility model has the advantages that：This kind reduces the outlet housing of noise, the outlet air
Cover is bolted with kitchen ventilator, is readily disassembled and cleans, and the cover body of the outlet housing is obliquely installed, and makes exhaust effect more preferable,
And the inside of cover body is fixed with filter screen, can cross the dust in filtering fume, one end of discharge pipe is equipped with check (non-return) valve, Neng Goufang
Only oil vapor backstreaming, the inner wall of discharge pipe are equipped with noise reduction layer, and noise reduction layer includes dampening foams, and the outer wall of dampening foams is equipped with noise reduction
Rubber wall reduces the noise generated during kitchen ventilator work.

Specific embodiment
Technical means, creative features, achievable purpose and effectiveness to realize the utility model are easy to understand, below
With reference to specific embodiment, the utility model is expanded on further.
As Figure 1-Figure 4, a kind of outlet housing for reducing noise, including kitchen ventilator 1 and cover body 3, the air outlet of kitchen ventilator 1
The threaded hole 7 being equipped with 2 surface of air intake plate is fixedly connected by bolt 9, easy to disassemble and cleaned, air intake plate 2 it is another
Side is fixedly connected with one end of cover body 3, and the inside of cover body 3 is fixed with filter screen 6, and filter screen 6 can cross the ash in filtering fume
Dirt, the other end of cover body 3 are equipped with discharge pipe 5, and the inner wall of discharge pipe 5 is equipped with noise reduction layer 8, and noise reduction layer 8 can reduce kitchen ventilator 1
The noise generated during work.
Wherein, cover body 3 is obliquely installed, and can increase the exhaust effect of the outlet housing.
Wherein, one end of discharge pipe 5 is equipped with check (non-return) valve, the oil vapor backstreaming that can prevent kitchen ventilator 1 from extracting out.
Wherein, noise reduction layer 8 includes dampening foams, and the outer wall of dampening foams is equipped with noise reduction rubber wall, can reduce oil smoke
The noise that machine 1 generates when working.
Wherein, the other end of cover body 3 is fixedly connected by connecting flange 4 with one end of discharge pipe 5, makes the more firm of connection
Gu and be readily disassembled, the oil stain on 5 surface of discharge pipe is cleaned.
