Abstract
The invention relates to the technical field of the elevator industry, in particular to a noise reduction and ventilation structure of an elevator car. The noise reduction and ventilation structure comprises a car body, the top of the car body is provided with a fan, the top wall, the left side wall, the right side wall and the rear side wall of the outside of the car body are respectively provided with a soundproof cotton layer, the left side wall, the right side wall and the rear side wall of the car body are respectively provided with an exhaust port, one end of each exhaust port is connected with a tee joint, the top end of each tee joint is connected with an upper one-way valve, and the bottom end of each tee joint is connected with a lower one-way valve. When the noise reduction and ventilation structure is used, the top wall, the left side wall, the right side wall and the rear side wall of the outside of the car body are respectively provided with one soundproof cotton layer, by means of the one-way valves, convection between air in the tee joints and air in the car body is formed, noise in the car body is greatly lowered, and ventilation performance of the car body is improved. The noise reduction and ventilation structure of the elevator car has the advantages of being simple in structure, reasonable in arrangement, low in manufacturing cost and the like.
Description
Technical field
The present invention relates to elevator industry technical field, particularly a kind of noise abatement aeration structure of lift car.
Background technology
In the time that elevator up and down reciprocatingly moves in hoistway, gas is instantaneous sharply to be compressed, between while car cab and hoistway, the gas at gap place is due to the sharply minimizing of flow area, speed with respect to envelope just can increase suddenly, therefore produce very large windage, these resistances and car effect, just produce windage noise.In addition, car belongs to leakproofness space, and its indoor air flow property is conventionally poor.So in order to ensure lift car passenger's traveling comfort, necessity is carried out noise reduction and is improved performance of ventilating lift car.
Summary of the invention
The object of the invention is to defect and deficiency for prior art, provide a kind of simple in structure, the noise abatement aeration structure of lift car reasonable in design, easy to use.
For achieving the above object, the technical solution used in the present invention is:
The noise abatement aeration structure of a kind of lift car of the present invention, comprise envelope, the top of described envelope is provided with fan, roof, left side wall, right side wall and the rear wall of described envelope outside are provided with Sound-proof material layer, left side wall, right side wall and the rear wall of described envelope are provided with exhausr port, exhausr port one end is connected with T-pipe joint, and the top of T-pipe joint is connected with check valve, and the bottom of T-pipe joint is connected with lower check valve.
Further, the cross-sectional plane of described exhausr port is bell mouth shape, and the exit skirt of exhausr port inwardly arranges.
Further, the positive lower end of described fan is provided with heater strip, and heater strip is connected with power supply.
Adopt after said structure, beneficial effect of the present invention is: the noise abatement aeration structure of a kind of lift car of the present invention, comprise envelope, the top of described envelope is provided with fan, roof, left side wall, right side wall and the rear wall of described envelope outside are provided with Sound-proof material layer, and left side wall, right side wall and the rear wall of described envelope are provided with exhausr port, and exhausr port one end is connected with T-pipe joint, the top of T-pipe joint is connected with check valve, and the bottom of T-pipe joint is connected with lower check valve.In the time that use is of the present invention, by the roof in envelope outside, left side wall, right side wall and rear wall, Sound-proof material layer is set, form convection current by the indoor air of check valve, T-pipe joint and envelope is set, greatly reduced the indoor noise of envelope, improve the indoor performance of ventilating of envelope.The advantages such as the present invention has simple in structure, arranges rationally, and cost of manufacture is low.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Description of reference numerals:
1, envelope; 1-1, exhausr port; 2, fan; 3, Sound-proof material layer; 4, seal closure;
5, T-pipe joint; 61, upper check valve; 62, lower check valve; 7, heater strip.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As shown in Figure 1, the noise abatement aeration structure of a kind of lift car of the present invention, comprise envelope 1, the top of described envelope 1 is provided with fan 2, fan 2 is connected with power supply, roof, left side wall, right side wall and the rear wall of described envelope 1 outside are provided with Sound-proof material layer 3, left side wall, right side wall and the rear wall of described envelope 1 are provided with exhausr port 1-1, exhausr port 1-1 one end is connected with T-pipe joint 5, the top of T-pipe joint 5 is connected with check valve 61, and the bottom of T-pipe joint 5 is connected with lower check valve 62.When elevator is in uphill process, the resistance of air makes check valve 61 and T-pipe joint 5 in off-state, and the wind that fan 2 is discharged is to discharge by lower check valve 62; When elevator is in decline process, the resistance of air makes lower check valve 62 and T-pipe joint 5 in off-state, and the wind that fan 2 is discharged is to discharge by upper check valve 61; Can effectively reduce like this noise.
Further, the cross-sectional plane of described exhausr port 1-1 is bell mouth shape, and the exit skirt of exhausr port 1-1 inwardly arranges, and contributes to so a large amount of air draughts, ensures indoor good air flow property.The exit skirt of exhausr port 1-1 can install louver additional, to ensure the safety in car, prevents that child from falling into.
Further, the positive lower end of described fan 2 is provided with heater strip 7, and heater strip 7 is connected with power supply, in the time that weather turns cold, user switches on to heater strip 7, and the wind that fan 2 blows out heats through heater strip 7, wind in car just becomes warm braw, has greatly improved the comfort property of car.
In the time that use is of the present invention, by the roof in envelope outside, left side wall, right side wall and rear wall, Sound-proof material layer is set, form convection current by the indoor air of check valve, T-pipe joint and envelope is set, greatly reduced the indoor noise of envelope, improve the indoor performance of ventilating of envelope.In addition, this is simple in structure, reasonable in design, low cost of manufacture.
The above is only preferred embodiments of the present invention, and the equivalence of doing according to structure, feature and principle described in patent claim of the present invention therefore all changes or modifies, and is included in patent claim of the present invention.
