Abstract
The utility model provides a novel air conditioner muffler, including casing, intake pipe and outlet duct, the casing both ends are provided with the choke, intake pipe and outlet duct are all in the choke extends to the casing, and the intake pipe stretches into length in the casing for the fourth of casing length, and the outlet duct stretches into length in the casing for the half of casing length, the one end that the outlet duct is located the casing is provided with the oil gallery. The utility model discloses the design of this muffler structure is simple reasonable, and intake pipe and outlet duct stretch into the interior design of casing and does not pass through the frequency for special size, whole muffler, can effectively eliminate the noise of all frequencies, and noise cancelling effect is good. The one end that the outlet duct lies in the casing is provided with the oil gallery, and when quick -witted oil spraying went out in the compressor motor, machine oil can flow in the pipeline, and the oil gallery on the outlet duct can make machine oil in time flow back in the motor, guarantees the lubrication of motor.
Description
Technical field
This utility model belongs to air-conditioning part field, particularly relates to a kind of air conditioner muffler.
Background technology
Domestic air conditioner also brings worry for us while bringing convenience to us, and air conditioning unit noise of equipment is on environment and uses the impact in room to be paid attention to by everybody.Wherein outdoor compressor is one of Main Noise Sources, generally increases deafener on the pipe arrangement of compressor for reducing noise.Generally there is the phenomenon that cannot eliminate certain frequency range noise in conventional expansion cell-type deafener, particularly with convertible frequency air-conditioner, this phenomenon becomes apparent from.And, the machine oil in compressor electric motor once spray will feed line, when pipeline is longer, machine oil cannot reflux in time, causes motor lack of lubrication.
Utility model content
This utility model is the best for existing air conditioner muffler erasure effect, the technical problem that machine oil cannot reflux in time, proposes one and can eliminate all frequency noise, and makes the air-conditioning deafener that machine oil refluxes in time.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of air-conditioning deafener, including housing, air inlet pipe and escape pipe, described housing two ends are provided with choke, described air inlet pipe and escape pipe are all in choke extends to housing, air inlet pipe stretches into 1/4th of a length of shell length in housing, escape pipe stretches into 1/2nd of a length of shell length in housing, and described escape pipe is positioned at one end of housing and is provided with spill port.
As preferably, described housing is cylindrical.
As preferably, described shell length is 150mm ~ 250mm.
As preferably, described diameter of the housing is 3 ~ 5 times of air inlet pipe diameter.
As preferably, described spill port is rounded, a diameter of 2 ~ 5mm.
Compared with prior art, advantage of the present utility model and have the active effect that this muffler structure designs advantages of simple, air inlet pipe and escape pipe stretch in housing and are designed as special size, and whole deafener is not over frequency, can effectively eliminate the noise of all frequencies, erasure effect is good.Escape pipe is positioned at one end of housing and is provided with spill port, and when compressor electric motor inner engine oil sprays, machine oil can flow in pipeline, and the spill port on escape pipe can make machine oil be back in time in motor, it is ensured that the lubrication of motor.Effectively preventing because pipeline is longer, machine oil cannot reflux in time, and causes the problem that the motor feels hot.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model deafener；
In the most each figure: 1, housing；2, air inlet pipe；3, escape pipe；31, spill port；4, choke.
Detailed description of the invention
In order to be better understood from this utility model, illustrate with embodiment below in conjunction with the accompanying drawings.
Embodiment: as it is shown in figure 1, a kind of air-conditioning deafener, including cylindrical shell, air inlet pipe and escape pipe, described housing two ends are provided with choke, and shell length is that L(does not include choke).Described air inlet pipe one end connects compressor, and the other end is in choke stretches into housing, and air inlet pipe stretches into length L in housing1For shell length L 1/4th.Escape pipe in choke stretches into housing, built-in length L2For shell length L 1/2nd.The contact site welded seal of air inlet pipe and escape pipe and choke or bind seals.Described escape pipe is positioned at one end of housing and is provided with the spill port of a diameter of 2mm, and when compressor electric motor inner engine oil sprays, machine oil can flow in pipeline, and the spill port on escape pipe can make machine oil be back in time in motor, it is ensured that the lubrication of motor.Effectively preventing because pipeline is longer, machine oil cannot reflux in time, and causes the problem that the motor feels hot.
Having the deafener of above structure, as sin2kL=1, sound deadening capacity is maximum, now the KL odd-multiple equal to x/2, and i.e. when L is equal to 1/4 wavelength or its odd-multiple, sound-damping qualities is maximum.As SIN function sin2kL=0, sound deadening capacity is equal to zero, and the now kL even-multiple equal to x/2, i.e. when L is equal to 1/2 wavelength or its integral multiple, sound-damping qualities is equal to zero.Sin2kL is periodic function, so sound-damping qualities TL is also to be i.e. periodic with the relation of frequency f with kL.Work as L2During=1/2L, 1/2 wavelength odd-multiple can be eliminated and pass through frequency;Work as L1During=1/4L, 1/2 wavelength even-multiple can be eliminated and pass through frequency.
Therefore, Papillary, whole deafener, not over frequency, can effectively eliminate the noise of all frequencies.
The above; it it is only preferred embodiment of the present utility model; it it is not the restriction that this utility model is made other form; any those skilled in the art are changed possibly also with the technology contents of the disclosure above or are modified as the Equivalent embodiments of equivalent variations is applied to other field; but it is every without departing from technical solutions of the utility model content; any simple modification, equivalent variations and the remodeling made above example according to technical spirit of the present utility model, still falls within the protection domain of technical solutions of the utility model.
