Below with reference to Fig. 1-Fig. 3, the piston compressor 100 according to the utility model embodiment is described.
According to model utility embodiment motor piston compressor 100, comprising: casing 1, crankcase 2, cylinder head 3 and air suction silencer 4.Crankcase 2 is located in casing 1, and crankcase 2 comprises the crank portion 21 of passing for bent axle, and crank portion 21 is provided with crankshaft hole 211, and the bent axle of piston compressor 100 is engaged in this crankshaft hole 211.One end of crank portion 21 is provided with cylinder part 22, limits cylinder chamber in cylinder part 22, and cylinder head 3 to be located in cylinder part 22 and shutoff cylinder chamber, and air suction silencer 4 is connected with cylinder head 3.
The plan view of crankcase 2 as shown in Figure 3, crank portion 21 with cylinder part 22 away from the other end be provided with crashproof portion 23, cylinder part 22 in crank portion 21 and crashproof portion 23 are respectively in the two ends of cylinder part 22 in the horizontal direction, crashproof portion 23 is semilune, the end face of the madial wall of the contiguous casing 1 in its end face away from crank portion 21 i.e. crashproof portion 23, this end face can be cambered surface.
According to the piston compressor 100 of the utility model embodiment; by arranging crashproof portion 23 on crankcase 2; crashproof portion 23 relative to the agent structure of crankcase 2 closer to the madial wall of casing 1; like this when producing vibration in the process that piston compressor 100 transports or operate; crashproof portion 23 can play a protective role to the agent structure of crankcase 2; collision can not be produced between the agent structure of crankcase 2 and casing 1; crankcase 2 can not be subject to damaged in collision, can improve the reliability of piston compressor 100 thus.
Preferably, the end face of the madial wall of the contiguous casing 1 in crashproof portion 23 is cambered surface, and the minimum range of the madial wall of this cambered surface and casing 1 is t5, wherein t5 >=4mm.Can ensure, between crashproof portion 23 and the madial wall of casing 1, there is certain distance thus, the possibility producing shock between this crashproof portion 23 and madial wall of casing 1 can be reduced, reduce noise, improve reliability.More preferably, crashproof portion 23 is configured to hollow-core construction, in example shown in the drawings of the present utility model, this crashproof portion 23 has through hole 231 structure that above-below direction runs through its thickness, the rigidity in crashproof portion 23 can be reduced thus, alleviate the rigid collision between crashproof portion 23 and housing, can noise be reduced further, improve reliability.
Alternatively, as shown in Figures 2 and 3, the upper-end surface of cylinder part 22 is provided with crashproof salient point 222, minimum range between crashproof salient point 222 and the inner roof wall of casing 1 is t7, t7 >=3mm, crashproof effect can be played by the top of this crashproof salient point 222 pairs of cylinder part 22 thus, reliability can be improved further thus.Preferably, crashproof salient point 222 is multiple and spaced apart setting on the upper-end surface of cylinder part 22, and the protection at the top of crashproof salient point 222 pairs of cylinder part 22 can be made thus more effective, stressed more even.
As depicted in figs. 1 and 2, minimum range between the end face away from cylinder chamber of cylinder head 3 and the madial wall of casing 1 is t1, minimum range between the end face away from cylinder chamber of air suction silencer 4 and the madial wall of casing 1 is t2, wherein t1 < t2.That is; the madial wall of cylinder head 3 distance casing 1 compared with air suction silencer 4 is nearer; thus when vibration occurs piston compressor 100; cylinder head 3 is due to more close to the madial wall of casing 1; thus air suction silencer 4 can be avoided to produce with the madial wall of casing 1 collide, can effectively protect air suction silencer 4.
Preferably, as shown in Figure 1-Figure 3, the first side wall face of cylinder part 22 is provided with vertical outward extending crashproof raised line 221, and the minimum range between crashproof raised line 221 and the madial wall of casing 1 is t3, wherein t3 < t2, t3 >=4mm.Wherein, the end face of the cylinder part 22 that the first side wall face of cylinder part 22 and cylinder head 3 are positioned at roughly is positioned at orthogonal two planes; crashproof raised line 221 extends from the first side wall towards the direction away from this first side wall face; the madial wall of the more contiguous casing 1 of crashproof raised line 221 thus; thus when vibration occurs piston compressor 100; the agent structure of crashproof raised line 221 pairs of crankcases 2 plays a protective role; avoid the agent structure of crankcase 2 and casing 1 to collide, and then the reliability of piston compressor 100 can be improved.
As shown in Figure 3, cylinder part 22 with the first side wall face away from the second side wall surface be provided with exhaust cavity portion 24, limit exhaust cavity in exhaust cavity portion 24, exhaust cavity be connected with outlet pipe 5, with by compression after refrigerant gas discharge.Second side wall surface and the first side wall face in cylinder part 22 mutually away from; exhaust cavity portion 24 is provided with the contiguous bumping post 241 extended towards the madial wall of casing 1; thus; bumping post 241 is less than the distance of agent structure relative to casing 1 inwall in exhaust cavity portion 24 relative to the distance of casing 1 inwall; thus when vibration occurs piston compressor 100; bumping post 241 can play a protective role to exhaust cavity portion 24; avoid the agent structure in exhaust cavity portion 24 and casing 1 to collide, and then the reliability of piston compressor 100 can be improved.
Alternatively, bumping post 241 is t4, t4 >=4mm with the minimum range of the madial wall of casing 1.Ensure certain distance between the madial wall that also can ensure bumping post 241 and casing 1 thus, produce the possibility of collision between the madial wall that can reduce bumping post 241 and casing 1, reduce noise, improve reliability.Preferably, bumping post 241 inside can be provided with groove, can reduce the rigidity of bumping post 241 thus, reduces the rigidity of the shock between bumping post 241 and the madial wall of casing 1.
Minimum range between the upper-end surface in crashproof portion 23 and the inner roof wall of casing 1 is t6, t6 >=3mm.Can ensure, between the upper-end surface in crashproof portion 23 and the inner roof wall of casing 1, there is certain gap thus, reduce the possibility producing shock between the upper-end surface in crashproof portion 23 and the inner roof wall of casing 1.Wherein alternatively, the housing upper end of piston compressor 100 is formed to the recessed groove 11 of enclosure interior, in the vertical direction, the roof of groove 11 is lower than the inner roof wall of casing 1, therefore, need to ensure that the minimum range between the upper-end surface in crashproof portion 23 and the roof of groove 11 is more than or equal to 3mm.
Be all known according to other configuration examples of piston compressor 100 of the utility model embodiment for those of ordinary skills as press part, motor section etc. and operation, no longer describe in detail here.
