The utility model discloses both satisfied national trade detection standard JG/T-194 and increased with money 2018's regulation, can effectively solve the problem of flowing backward, cross cigarette, string flavor again, overcome simultaneously because of the inside static pressure of flue is big, and the problem of the vortex and the air curtain of formation.

Description

Smoke-proof pressure-variable exhaust passage for residential kitchen and bathroom

Technical Field

The utility model belongs to the technical field of kitchen guarding's equipment, a kitchen guarding smoke protection exhaust passage structure is related to, concretely relates to house kitchen guarding smoke protection vary voltage exhaust passage structure.

Background

The existing residential kitchen and bathroom exhaust duct generally adopts a cement prefabricated integrally-formed flue in the residential exhaust duct standard (16J916) of the building industry standard of the people's republic of China, is of a hollow cylinder type with a guide valve, and does not fundamentally solve the problems of backflow of smoke, smoke tainting and odor tainting between an upper floor and a lower floor. When in the flue is arranged into to air inlet flue gas, can meet with the flue gas of lower floor up-ward row, the two meets and can form vortex and air curtain, and this vortex and air curtain can go upward production to the flue gas of lower floor and hinder, in case the air inlet check valve is because of long-time the use by the greasy dirt adhesion, and when causing to open failure, the flue gas is because of going upward there is the hindrance, just can be to indoor string cigarette, cluster flavor.

At present, some technologies appear in the market, and some of the problems are solved to a certain extent. For example, the utility model patent with application number 202010124244.6 discloses a building air flue and installation application method with air inlet ventilation function solves above-mentioned problem through setting up vice exhaust passage in the main exhaust passage, but vortex and air curtain problem are effectively solved to this scheme. The utility model with application number 201220475260.0 discloses a gas flow adjusting structure of an exhaust passage of a residential kitchen and bathroom, which comprises an exhaust passage unit, a cross guide plate and a multifunctional plate, wherein the cross guide plate and the multifunctional plate are intermittently and alternately arranged in the same or different exhaust passage units; although the scheme is designed with an air flow adjusting structure, the air flow adjusting structure is easy to be adhered by oil stains after being used for a long time, so that the function failure is caused.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an exhaust passage rational in infrastructure, excellent in use effect had both satisfied national trade detection standard JG/T-194 and had increased charge 2018's regulation, can effectively solve the problem of flowing backward, string cigarette, string flavor again, has overcome simultaneously because of the inside static pressure of flue is big, and the problem of the vortex and the air curtain of formation.

The utility model adopts the technical proposal that: the utility model provides a house kitchen guarding smoke protection vary voltage exhaust passage which characterized in that: comprises a main flue, an auxiliary flue and an exhaust port, wherein the auxiliary flue and the exhaust port are positioned in an inner cavity of the main flue;

the main flue is provided with a plurality of exhaust ports, the exhaust ports are fixedly provided with the auxiliary flues, and kitchen and bathroom smoke is guided into the main flue through the exhaust ports and the auxiliary flues;

and a plurality of inverted V-shaped pressure transformation mechanisms are fixedly arranged in the inner cavity of the main flue, so that 3 small exhaust ports are formed in the main flue.

Preferably, the cross section of the auxiliary flue is L-shaped, and the included angle of the cross section is larger than 90 degrees.

Preferably, the top of the secondary flue is also fixedly provided with a first guide plate expanding outwards.

Preferably, a second guide plate is fixedly arranged at the bottom of the main flue, and the second guide plate and the first guide plate are positioned on the same vertical line.

Compared with the prior art, the utility model discloses following beneficial effect has:

(1) the auxiliary flue is additionally arranged in the exhaust port of the main flue, so that flue gas independently exhausted by each household can independently move upwards, and the opportunities of backflow, smoke tainting and odor tainting are reduced.

(2) The main flue is additionally provided with a plurality of pressure changing mechanisms which are inverted splayed, so that 3 small exhaust ports are formed in the main flue, the flue gas is accelerated to quickly move upwards, and the opportunity of forming vortex and air curtain is reduced.

(3) The top of the auxiliary flue and the bottom of the main flue are additionally provided with guide plates, so that the flue gas in the auxiliary flue can be quickly guided into the main flue.
