Embodiment
In order to make technological scheme of the present invention clearly, below in conjunction with accompanying drawing, pump body structure of the present invention and compressor are described in further detail.Should be appreciated that specific embodiment described herein only in order to explain that the present invention is not intended to limit the present invention.
See Fig. 2 to Figure 15, as shown in Figure 2, the pump body structure of one embodiment of the invention, comprise the baffler 1, upper flange 2, cylinder 3 and the lower flange 4 that set gradually along axle, the opening of cylinder 3 is communicated with the exhaust port 21 of upper flange 2.Baffler 1 in the present embodiment comprises the lug boss 11 of sealing and is around in the shirt rim 12 of lug boss 11 weeks sides, and lug boss 11 is in ring, and lug boss 11 and shirt rim 12 are wholely set, see shown in Fig. 3 to Fig. 5.Upper flange 2 partly runs through baffler 1, makes baffler 1 be set on upper flange 2, forms silencing cavity 5 with upper flange 2.When the lug boss 11 of baffler 1 is set on upper flange 2, the shirt rim 12 of baffler 1 contacts with upper flange 2, forms silencing cavity 5 with upper flange 2.
Like this, the noise that the opening through cylinder is discharged enters in silencing cavity 5 through the exhaust port 21 of upper flange 2, due to the sealing configuration of silencing cavity 5, makes this silencing cavity have the effect of sound absorption, sound insulation, thus significantly reduces the Middle and low frequency noise of compressor.
The position that upper flange 2 contacts with the shirt rim 12 of baffler 1 is provided with air vent 22, and preferably, air vent 22 is spirality, see shown in Fig. 6 to Fig. 8.Air vent 22 is communicated with silencing cavity 5 and the external world, and the pressurized gas in silencing cavity 5 are discharged by air vent 22.Air vent 22 is set to spirality, makes compressor form swirling eddy in exhaust process, can effectively cut down high-pressure pneumatic noise, thus reduce the noise of compressor.
More preferably, air vent 22 is bent to the side of upper flange in the same direction from the middle part of upper flange 2, and namely the round ring boss of air vent 22 through upper flange 2 upper surface, is convenient to the processing of upper flange 2 like this.In the present embodiment, the setting bent in the same direction by air vent 22, can be guided the exhaust airstream of compressor, is convenient to form swirling eddy in the exhaust process of compressor.When air-flow is discharged from silencing cavity 5 through air vent 22, air-flow rotates along same direction, and refrigeration oil sticks in inner walls after being thrown toward the inner walls of compressor, thus reduces the oil content of air-conditioning system, improves the performance of compressor.
In the present embodiment, the cross section of air vent 22 can be uniform section, also can be variable cross section.When the cross section of air vent 22 is variable cross section, the sectional dimension of air vent 22 increases along the middle part of upper flange 2 gradually to the direction of the side of upper flange 2.As shown in Figure 13 to Figure 14, on the direction of the middle part of upper flange 2 to the side of upper flange 2, the sectional dimension of air vent is respectively a, b, c, and a < b < c.Like this, air vent 22 is increasing with the gap of the position that the shirt rim 12 of baffler 1 contacts, and can ensure the sealing of silencing cavity 5, is convenient to again high-pressure pneumatic noise simultaneously and discharges from air vent 22, restrained effectively noise.Certainly, in other embodiments, air vent 22 can also be other variable cross sections, and the pass as the sectional dimension of air vent is a > b > c.
As shown in Figures 9 to 11, the sectional shape of air vent 22 can be other possible shapes such as rectangle, circular arc, trapezoidal or T-shaped.In the present embodiment, the sectional shape of air vent 22 should be determined according to the air displacement of compressor, to reach optimum sound-deadening and noise-reducing effect.
More preferably, the quantity of air vent 22 is one or more.When the quantity of air vent 22 is more than one, multiple air vent 22 is evenly distributed on upper flange 2.In all directions that can ensure upper flange like this, exhaust evenly, ensures the effect of sound-deadening and noise-reducing further.In the present embodiment, the quantity of air vent 22 also should be determined according to the air displacement of concrete compressor.
In order to improve the noise reduction of this pump body structure further, upper flange 2 is also provided with the resonant cavity be communicated with air vent 22, and resonant cavity and air vent 22 one_to_one corresponding are arranged.Certainly, in other embodiments, an air vent 22 can be communicated with multiple resonant cavity simultaneously.Preferably, resonant cavity is arranged on the position near baffler 1 shirt rim 12.When air-flow enters resonant cavity by air vent 22, generation is resonated thus is reached the object of sound-deadening and noise-reducing.
Certainly, in other embodiments, also different noise reduction resonant frequencies can be determined by the frequency of concrete compressor, to reaching best sound-deadening and noise-reducing effect.Now, should according to the shirt rim size of noise reduction resonant frequency determination baffler, the parameters such as the sectional dimension of air vent and the sectional shape of air vent.
The invention still further relates to a kind of compressor, comprise the pump body structure of above-mentioned any embodiment.
Pump body structure of the present invention and compressor, the silencing cavity formed by baffler and upper flange carries out absorbing sound and insulating against sound, and reduces the Middle and low frequency noise of compressor; Meanwhile, the high-pressure pneumatic noise that pump assembly produces can be discharged by the air vent that upper flange is offered, and high-pressure pneumatic noise is cut down effectively, thus reduces the aerodynamic noise of compressor.
The above embodiment only have expressed several mode of execution of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
