Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, rotary reciprocating compressor of the present utility model and air conditioner are further elaborated.Should be appreciated that specific embodiment described herein only for explaining the utility model, and be not used in restriction the utility model.
Referring to figs. 1 through Fig. 4, the rotary reciprocating compressor of the utility model one embodiment, comprises cylinder block 1, piston 2, bent axle 9 and connecting rod 10.Cylinder block 1 has cylinder, and piston 2 is placed in described cylinder, described cylinder is arranged cylinder head assembly 3.Piston 2 connects bent axle 9 by connecting rod 10, and piston 2 is provided with elongate recesses 21 and the annular groove 22 being communicated with elongate recesses 21.Cylinder block 1 is provided with the side opening 11 being communicated with elongate recesses 21, and side opening 11 is communicated with the exhaust noise silencing chamber on cylinder block 1 by connecting tube 4.Preferably, the angle between the center line of side opening 11 and cylinder orifice plate face is 10 °-60 °.Namely the angle between the center line of side opening 11 and cylinder-bore end face is 10 °-60 °.
Wherein, connecting tube 4 and side opening 11 welded seal; Connecting tube 4 is tightly connected with the noise reduction lid 5 in described exhaust noise silencing chamber, and namely connecting tube 4 runs through the noise reduction lid 5 in exhaust noise silencing chamber and is communicated with described exhaust noise silencing chamber, adopts and be tightly connected between connecting tube 4 and noise reduction lid 5.Connecting tube 4 is tightly connected with the noise reduction lid 5 in exhaust noise silencing chamber, and the connecting tube 4 by being tightly connected with noise reduction lid 5 after compressor air-discharging side pressurized gas out enter into silencing cavity flows into elongate recesses 21.
Rotary reciprocating driven compressor mode is: be with dynamic crankshaft 9 to rotate by motor 7, crankshaft crank is connected with connecting rod 10, connecting rod 10 promotes piston 2 and to move reciprocatingly in the cylinder (compression chamber) of cylinder block 1 pressurized gas, is discharged to outside inside exhaust pipe 6 by silencer.Silencer is exhaust noise silencing chamber.
Rotary reciprocating compressor, by having certain lubricant oil in lower casing 8, rotates the component of oiling method to the pump housing by bent axle 9 and realizes lubrication and cooling effect.In running, flow into piston 2 and cylinder block 1 section of being sealed and matched by introducing a part of pressurized gas from exhaust side, thus form gas bearing between piston 2 and cylinder-bore.
Preferably, side opening 11 is circular hole, easily processes.Because piston 2 is when pressurized gas, can be subject to gas force effect, bent axle 9 and cylinder-bore have an eccentric distance, arrange the effect that side opening 11 can also reduce compressive force, thus reduce compression power consumption.The shape of side opening 11 does not limit, such as, also can be square hole or elliptical aperture etc.
As a kind of embodiment, annular groove 22 is more than 4mm to the distance of the pressurized gas end face 23 of piston 2.Namely piston 2 is more than 4mm with the seal distance of described cylinder.Seal distance is limited to more than 4mm can ensure effective sealing cylinder, to such an extent as to the gas of annular groove 22 is not by inflow compression chamber.
As a kind of embodiment, on the axial direction of piston 2, the stroke of piston 2 is less than or equal to the length of elongate recesses 21.Or on the axial direction of piston 2, the stroke of piston 2 is less than or equal to the length of elongate recesses 21 and the width sum of annular groove 2.So can ensure that the pressurized gas physical efficiency flowing into side opening 11 is communicated in annular groove 2 all the time, guarantee to keep certain seal distance with the pressurized gas end face 23 of piston simultaneously, guarantee that the pressurized gas introduced from side opening 11 does not flow in compresser cylinder.
The utility model also relates to a kind of air conditioner, comprises the rotary reciprocating compressor of above-mentioned arbitrary technological scheme, because air conditioner is prior art except above-mentioned rotary reciprocating compressor, repeats no more.
The rotary reciprocating compressor of above embodiment and air conditioner, piston is provided with elongate recesses and the annular groove being communicated with elongate recesses, cylinder block is provided with the side opening being communicated with elongate recesses, side opening is communicated with the exhaust noise silencing chamber on cylinder block by connecting tube, thus gas bearing is formed between piston and cylinder-bore, reduce the friction power loss between cylinder and piston, effectively reduce lubricant oil oil mass, promote compressor performance; Processing technology is simple, reduces compressor cost; Minimizing compressor enters the lubricant oil in refrigeration system, improves the heat exchange efficiency of refrigeration system, reduces system energy consumption, and the slow-speed of revolution of rotation reciprocating compressor is run.
The above embodiment only have expressed several mode of execution of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
