Description

Exhaust duct of internal circulation type range hood

Technical Field

The invention belongs to the technical field of auxiliary components of range hoods, and particularly relates to an exhaust pipeline of an internal circulation range hood.

Background

A range hood is an electric appliance for sucking and cleaning oil fume generated during cooking in a household kitchen, not only can well complete the functional function, but also has the decoration concept of fusing the modern kitchen pattern.

The gas that the lampblack absorber was handled discharges through exhaust pipe, because gaseous high temperature makes traditional exhaust pipe receive the harm very easily in the course of the work, great shortening its life.

Disclosure of Invention

Technical problem to be solved

Aiming at the defects of the prior art, the invention provides an exhaust pipeline of an internal circulation type range hood, which solves the problem that the service life of the exhaust pipeline of the existing range hood is shortened due to overhigh gas temperature.

(II) technical scheme

In order to achieve the purpose, the invention is realized by the following technical scheme: an exhaust duct of an internal circulation type range hood comprises an exhaust duct body, wherein two groups of mounting notches are formed in the inner side wall of the exhaust duct body, the two groups of mounting notches are vertically distributed relative to the inner central position of the exhaust duct body, the distance between every two adjacent mounting notches is the same, a fixed seat is arranged inside each mounting notch, fixing base fixed mounting is in the inside of installation notch, and is a plurality of the equal hinge in inside of fixing base has the connecting axle, and is a plurality of the one end that the fixing base was kept away from to the connecting axle extends to the outside of installation notch, and is a plurality of the connecting axle is kept away from a plurality of elastic expansion material poles of the equal fixedly connected with in one end surface of fixing base, a plurality of the connecting axle is kept away from the equal slip cap of one end surface of fixing base and is equipped with connecting sleeve, and is a plurality of the connecting sleeve is kept away from the equal fixedly connected with in one end of connecting axle and is divided the cigarette board.

Preferably, a plurality of connecting shafts are provided with connecting holes at one ends close to the fixing seat.

Preferably, a plurality of clamping groove are all seted up to connecting sleeve's inside wall, and a plurality of clamping groove's shape is arc.

Preferably, the smoke distribution plates are all semicircular in shape, and the radius of the smoke distribution plates is the same as the radius of the section circle of the smoke exhaust pipeline body.

Preferably, the interior of the smoke separating plate is filled with an adsorbing material.

Preferably, a plurality of material passing holes are formed in the upper side wall and the lower side wall of the smoke distribution plate.

The working principle is as follows: when the exhaust duct is used, when the exhaust duct needs to be installed or disassembled, the smoke separating plates can be rotated to enable the two smoke separating plates which are symmetrical about the middle position of the exhaust duct to form a complete circle, the radius of each smoke separating plate is the same as that of the section circle of the exhaust duct body, the two smoke separating plates which form the complete circle can support the flexible exhaust duct, the installation or disassembly convenience can be greatly improved, in the using process, the smoke separating plates are rotated to enable the smoke separating plates to form a certain included angle with the inner side wall of the exhaust duct body, when high-temperature gas enters the interior of the exhaust duct body, the high-temperature gas firstly collides with the inclined smoke separating plates and is transmitted forwards after passing through the smoke separating plates and the adsorption material, the high-temperature gas can move forwards along the arrangement trend of the smoke separating plates, the excessive contact between the inner wall of the duct and the high-temperature gas can be reduced, and the service life of the high-temperature gas can be greatly prolonged, meanwhile, when the treated gas passes through the smoke separating plates layer by layer, the treated gas can be purified once every time the treated gas passes through the smoke separating plates layer by layer, and the neatness of the discharged gas can be further ensured.

(III) advantageous effects

The invention provides an exhaust duct of an internal circulation range hood. The method has the following beneficial effects:

1. this exhaust duct of inner loop formula range hood, when needs are with exhaust duct installation or dismantlement, rotatable smoke-separating plate for its two smoke-separating plates about exhaust duct intermediate position symmetry constitute a complete circle, because its radius of smoke-separating plate is the same with the radius of exhaust duct body cross-section circle, two smoke-separating plates that form the complete circle this moment can support soft exhaust duct, the convenience of improvement installation or dismantlement that can be great.

2. This internal circulation formula range hood's exhaust pipe, in the use, rotatory smoke-separating plate, make its and the inside wall of exhaust pipe body form certain contained angle, when high-temperature gas gets into the inside of exhaust pipe body, at first with the smoke-separating plate of slope to the collision, transmit forward again behind smoke-separating plate and adsorbing material, high-temperature gas can be along the trend forward motion of arranging of smoke-separating plate, reducible pipeline inner wall and high-temperature gas's excessive contact, its life of improvement that can be great.

3. This internal circulation formula range hood's exhaust duct, in the in-process of using, when the gas through handling when the smoke separating plate layer upon layer, once every process, it can be purified once, can further ensure the clean and tidy nature of the gas of getting rid of.
