Embodiment
In order to make object of the present invention, technological scheme and advantage clearer, below in conjunction with drawings and Examples, rotary compressor of the present invention and air conditioner are further elaborated.Should be appreciated that specific embodiment described herein, only for explaining the present invention, is not intended to limit the present invention.
Referring to figs. 1 through Fig. 5, rotary compressor one embodiment's of the present invention pump body structure comprises bent axle 1, upper flange 2, upper baffler (not shown), upper cylinder 3, central diaphragm 4, lower cylinder 5, lower flange 6 and bottom silencer 7, upper cylinder 3, central diaphragm 4, lower cylinder 5, lower flange 6 and bottom silencer 7 set gradually from top to bottom, upper flange 2 is arranged on the upper end portion of upper cylinder 3, and described upper baffler is placed in the top of upper flange 2.Between bottom silencer 7 and lower flange 6, form the relief opening that the first intermediate cavity 8, the first intermediate cavity 8 are communicated with lower cylinder 5, on bottom silencer 7, be provided with first row pore 9.Between described upper baffler and upper flange 2, form the second intermediate cavity, described the second intermediate cavity is communicated with the relief opening of upper cylinder 3, on described upper baffler, is provided with second row pore.Upper cylinder 3 and lower cylinder 5 are all as one-level compression cylinder.The exhaust of lower cylinder 5 is discharged described pump body structure from first row pore 9, as shown in the direction of arrow in Fig. 1.And the exhaust of upper cylinder 3 is discharged described pump body structure from described second row pore.
As a kind of embodiment, on bottom silencer 7, the quantity of first row pore 9 is one, and as shown in Figure 2, the aperture of first row pore 9 (diameter) is d1, and wherein d1 is φ 10mm-φ 14mm, and the aperture of first row pore 9 is preferably φ 12mm herein.
As a kind of embodiment, on bottom silencer 7, the quantity of first row pore 9 is two, and as shown in Figure 4, the aperture of first row pore 9 is d2, and wherein d2 is φ 6mm-φ 8mm, and d2 is preferably φ 7mm.The center line of two first row pore 9 relative bottom silencers 7 is symmetrical arranged.
As a kind of embodiment, on bottom silencer 7, the quantity of first row pore 9 is three, and as shown in Figure 4, the aperture of first row pore 9 is d3, and wherein d3 is φ 4mm-φ 6mm.D3 is preferably φ 5mm.In three first row pores 9, wherein the center line of two relative bottom silencers 7 is symmetrical arranged, or three first row pores 9 are evenly distributed on same circumference.
The quantity of first row pore 9 also can be more than three, and the sectional area summation of three above first row pores 9 is less than or equal to 113mm
2.
The invention still further relates to a kind of air conditioner, comprise the rotary compressor of above-mentioned arbitrary technological scheme, because air conditioner is prior art except described rotary compressor, be no longer described in detail herein.
