Abstract
The present case is a silencing device for air conditioner pipeline, includes: a silencing device for air conditioner pipeline, includes: compressor exhaust pipe, its lateral wall is equipped with the speaker, the sound control that disappears system ware integrated circuit board, it is located with the welded mode inside the compressor exhaust pipe cavity, and locate this cavity side wall, the sensor, it locates the compressor exhaust pipe lateral wall, and is located between the sound control that disappears system ware integrated circuit board and the speaker, wherein, the sound control that disappears system ware integrated circuit board is used for the signal acquisition of sensor, speaker, and with control the mode that the speaker sent the opposition noise is used for falling makes an uproar. The present case utilization disappears sound control system ware integrated circuit board and has reduced the noise of air conditioner pipeline by a wide margin, and compressor exhaust pipe blast pipe lateral wall is located respectively to the speaker, through reasonable structural design for volume, weight do not have obvious increase, have reached better noise cancelling effect.
Description
Technical field
This utility model relates to silencing means, particularly relates to a kind of silencing means for air-conditioning duct.
Background technology
Air-conditioning and air conditioner, refer to and use artificial means, the process that the parameters such as the temperature of building/structures environment air, humidity, cleanliness factor, speed are adjusted and are controlled.Generally comprise several major parts and other auxiliary equipment such as low-temperature receiver/heat resource equipment, cold and hot medium distributing system, end equipment, mainly include water pump, blower fan and pipe-line system.The cold and hot amount utilizing transmission & distribution then is responsible for by end equipment, specifically processes air, makes the air parameter of target environment reach requirement.
Pipe-line system, due to the impact rotated by motor and fan blade, generally has significant low frequency periodic noise in its radiated noise, above-mentioned noise brings bigger bothering, and carries out suppressing significant to it.Traditional noise reduction schemes is to set up passive deadener or structure, such as cotton, the reactive muffler etc. of absorbing sound.But for low frequency spectrum lines noise, said method not only volume, weight are big, also can bring the pressure loss, affect the performance of exhaust fan.Therefore, its noise of product general tree on the market is acted upon at present.
Utility model content
For overcoming the deficiencies in the prior art, the purpose of this utility model is in that to provide the silencing means for air-conditioning duct of a kind of simple in construction, good muffling effect.
For achieving the above object, this utility model is achieved through the following technical solutions:
A kind of silencing means for air-conditioning duct, including:
Compressor exhaust pipe 1, its sidewall is provided with speaker 4；
Muffling controller board 3, it is positioned at described compressor exhaust pipe cavity inside in a welding manner, and is located at this cavity sidewalls；
Sensor 2, it is located at compressor exhaust pipe sidewall, and between described muffling controller board and speaker；
Wherein, described muffling controller board is used for the signals collecting of described sensor, speaker, and to control in the way of described speaker sends anti-phase noise for noise reduction.
Preferably, the described silencing means for air-conditioning duct, wherein, described muffling controller board comprises the power amplifier module that can drive described speaker.
Preferably, the described silencing means for air-conditioning duct, wherein, in described compressor exhaust pipe, it is additionally provided with guide duct.
Preferably, the described silencing means for air-conditioning duct, wherein, between described muffling controller board and cavity sidewalls, it is provided with puigging.
The beneficial effects of the utility model: this case utilizes muffling controller board to considerably reduce the noise of air-conditioning duct, speaker is respectively arranged on compressor exhaust pipe exhaustor sidewall, by rational structural design so that volume, weight significantly do not increase, reach good erasure effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the silencing means for air-conditioning duct described in this utility model one embodiment.
Wherein, 1-compressor exhaust pipe, 2-sensor, 3-muffling controller board, 4-speaker.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail, to make those skilled in the art can implement according to this with reference to description word.
A kind of silencing means for air-conditioning duct, refers to accompanying drawing 1, including:
