Abstract
The utility model relates to the technical field of the elevator industry, in particular to a noise-reduction ventilating structure for a car of an elevator. The noise-reduction ventilating structure for the car of the elevator comprises a car body, wherein a fan is arranged on the top of the car body; sound-insulation cotton layers are respectively arranged on the top wall, the left side wall, the right side wall and the rear side wall of the outside of the car body; exhausting openings are respectively formed in the left side wall, the right side wall and the rear side wall of the car body; one end of each exhausting opening is connected with a three-way joint; the top of each three-way joint is connected with an upper one-way valve; and the bottom of each three-way joint is connected with a lower one-way valve. When the noise-reduction ventilating structure for the car of the elevator is used, the sound-insulation cotton layers are respectively arranged on the top wall, the left side wall, the right side wall and the rear side wall of the outside of the car body, air in the three-way joints and air in the car body are subjected to convection by using the one-way valves, the noise in the car body is greatly reduced, and the ventilation performance in the car body is improved. The noise-reduction ventilating structure for the car of the elevator has the advantages of simple structure, reasonable arrangement, low manufacturing cost and the like.
Description
Technical field
The utility model 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.
Utility model content
The purpose of this utility model is for the defect of prior art and deficiency, provides 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 adopted in the utility model is:
The noise abatement aeration structure of a kind of lift car described in the utility model, 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, the utility model beneficial effect is: the noise abatement aeration structure of a kind of lift car described in the utility model, 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, 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 using the utility model, 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 utlity model has simple in structurely, arrange rationally, the advantage such as cost of manufacture is low.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
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 utility model is further described.
As shown in Figure 1, the noise abatement aeration structure of a kind of lift car described in the utility model, 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 using the utility model, 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 utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
