Specific embodiment
One of core of the invention is to provide a kind of compressor silencer, so as to further decrease the exhaust of compressor
Noise reaches the higher requirement of user.
Another core of the invention is to provide a kind of compressor using above-mentioned compressor muffler.
Another core of the invention is to provide a kind of temperature equipment using above-mentioned compressor.
In order to enable those skilled in the art to better understand the solution of the present invention, with reference to the accompanying drawings and detailed description
The present invention is described in further detail.
Disclosed in this invention compressor silencer, including expansion cavity 1, in addition to this, which also wraps
The noise reduction expansion pipe 2 being fixed in expansion cavity 1 is included, noise reduction expansion pipe (2) includes at least a noise reduction segment, and noise reduction
Segment includes that middle part expands section 21 and expands the necking section 22 at 21 both ends of section positioned at middle part, and the end of necking section 22 is to expand with noise reduction
The hatch frame that the inside of pipe 2 communicates is opened, as shown in figs. 2 and 4.
It not only include expansion cavity 1 it can be seen from above-described embodiment in compressor silencer disclosed in this invention,
And noise reduction expansion pipe 2 is also provided in expansion cavity 1, noise reduction expands pipe 2 and includes at least a noise reduction segment, the noise reduction segment
Section 21 is expanded including middle part and expands the necking section 22 at 21 both ends of section positioned at middle part, and the end of necking section 22 is hatch frame.
Substantially, noise reduction expansion pipe 2 constitutes resistant noise-reducing device, after adding noise reduction expansion pipe 2 in expansion cavity 1,
Compressor muffler is formed complex muffler, corresponding with expansion cavity frequency in exhaust noise when compressor is exhausted
A part of noise will even be eliminated first by the weakening of expansion cavity 1, and in exhaust noise with the corresponding a part of noise reduction expansion pipe 2
Noise will be expanded the weakening of pipe 2 by noise reduction and even be eliminated, and compared with the prior art, adding for noise reduction expansion pipe 2 effectively compensates for list
The limited defect of expansion cavity noise reduction frequency range, the compressor silencer weaken making an uproar for the frequency range that former muffler can not be eliminated simultaneously
Sound, this just effectively reduces the overall noise of compressor air-discharging, to reach the higher requirement of user.
It will be readily appreciated by those skilled in the art that can be set on noise reduction expansion pipe 2 to reach better erasure effect
Multiple above-mentioned noise reduction segments are set, multiple noise reduction segments should connect, and the connection between different noise reduction segments, each disappears for convenience
22 cross-sectional area of necking section in syllable section is all the same, but needs to guarantee that section 21 is expanded at the middle part in any two noise reduction segment
Cross-sectional area is different, and in resistant noise-reducing device, the divergence ratio that this allows for any two noise reduction segment is different, and different expansions
The resistant noise-reducing device of ratio can eliminate the noise of different frequency, this erasure effect for allowing for the compressor silencer further mentions
It is high.
Certainly, in addition to this there are also a kind of mode, multiple above-mentioned noise reductions expansion pipes 2 can be set in expansion cavity 1, and appoint
Only one the equal noise reduction segment of pipe 2 is expanded in noise reduction of anticipating, and in any one noise reduction segment, the cross section of section 21 is expanded at middle part
The long-pending ratio with the cross-sectional area of necking section 22 is known as divergence ratio, and the divergence ratio of any two noise reduction segment is different.Difference expands
The resistant noise-reducing device of ratio can eliminate the noise of different frequency, this again such that the erasure effect of the compressor silencer into one
Step improves.
Noise reduction expansion pipe 2 can be directly welded in expansion cavity 1, and expansion cavity 1 can also be indirectly attached to by other component
It is interior, in order to facilitate the installation of, mounting plate 3 is welded in the expansion cavity 1 in the present embodiment, and noise reduction enlargement of pipe pipe 2 is mounted on
In loading board 3, as shown in Figure 2, substantially, noise reduction expansion pipe 2 is mounted on by the way in expansion cavity 1 by mounting plate 3, may be used also
The pulsation of compressor air-discharging is effectively reduced.
As shown in Figure 3 and Figure 5, mounting plate 3 is in specifically rectangle, and mounting plate 3 is welded on vertically in expansion cavity 1, installation
The corner part that plate 3 is contacted with expansion cavity 1 is bottom roundings, and bottom roundings design is primarily to avoid interfering with expansion cavity 1.
It further, is top fillet positioned at the angle of bottom roundings diagonal positions, top fillet is primarily to keep away
Exempt to be interfered with the shaft of compressor.
As shown in figs. 3 and 5, offer through-hole on mounting plate 3, through-hole is used to pass through for noise reduction expansion pipe 2, and with disappear
It expands section 21 and is weldingly connected in middle part in sound expansion pipe 2.
A kind of compressor is also disclosed in the present invention, which is provided with muffler, and the muffler is above-mentioned
Compressor silencer disclosed in any one.
