Abstract
The utility model relates to a sound-insulation air passing port belonging to a ventilating device, in particular to an indoor ventilating device. The sound-insulation air passing port comprises a box body, wherein the front end and the back end of the box body are respectively provided with an air inlet and an air outlet, and a passage from the air inlet to the air outlet is an air passage. The utility model has the key technology that the inner wall of the box body is provided with baffle plates up and down in a staggered way, so that the air passage forms a roundabout air passage. The utility model has the beneficial effects that the utility model has the very good functions of noise reduction and sound insulation and enhances the comfort level of a dwelling environment.
Description
Technical field:
The air port is crossed in sound insulation, belongs to ventilation unit, especially indoor ventilator unit.
Background technology:
Existing indoor ventilation unit as air-conditioning, because its air channel of crossing the air port is linear, so ventilate or noise is arranged during ventilation, influences living environment.
Summary of the invention:
Problem to be solved in the utility model is exactly the air port of crossing that a kind of sound insulation, noise reduction are provided at above deficiency.Its technical scheme is as follows:
It comprises casing, has air inlet and air outlet at the casing front and back ends, and air inlet is the air channel to the passage of air outlet, and its key technology is to misplace up and down at cabinet wall to be provided with dividing plate, makes the air channel constitute circuitous air channel.
The beneficial effect that compared with prior art the utlity model has is to have good noise reduction, deadening, improves the comfort level of living environment.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model A-A generalized section.
The specific embodiment:
Referring to Fig. 1, Fig. 2, the utility model comprises casing 2, has air inlet 1 and air outlet 3 at casing 2 front and back ends, and air inlet 1 is the air channel to the passage of air outlet 3, its key technology is to misplace up and down at casing 2 inwalls to be provided with the dividing plate of being made by sound-absorbing material 4, makes the air channel constitute circuitous air channel.
The course of work of the present utility model is: air is after air inlet enters casing, circuitous mobile along the dividing plate that sound-absorbing material is made, air is in process of flowing, sound-absorbing material is with the propagation of wave absorption or partition sound wave, air after so repeatedly absorbing, cut off flows out from air outlet again, thereby reaches the purpose of noise reduction, sound insulation.
