Abstract

The utility model relates to a cylinder and baffle structure of a compressor, which comprises a compressor cylinder whose center forms a compression space. The walls of the cylinder form a baffle groove communicated with the compression space. The inner part of the baffle groove can be embedded by a baffle used for dividing the compression space into an air sucking space and an air discharging space in a repeated moving mode. The bottom of the baffle groove is provided with a spring supporting one end of the baffle. The two wall surfaces contacted by the baffle groove and the baffle form tooth grooves. The two sides contacted by the baffle and the baffle groove form teeth corresponding to the tooth grooves in the baffle groove, and the teeth can be embedded in the tooth grooves in a sliding mode. The tooth grooves formed by the two wall surfaces of the baffle groove are symmetrically formed by the two wall surfaces. Because the tooth grooves and the teeth, which mutually correspond and are mutually embedded, are formed between the baffle groove and the baffle, the repeated move of the baffle in the baffle groove is restricted and the distance existing from the top end of the baffle and the top end of the cylinder is reduced. Therefore, the leakage is reduced and the noise generated by vibration is reduced.

Description

Compresser cylinder and baffle arrangement

Technical field

The utility model relates to a kind of compressor, particularly relates to a kind of compresser cylinder and baffle arrangement that can reduce leakage and vibrate the impact noise that is produced.

Background technique

Under the ordinary circumstance, rotary compressor be with running shaft that motor combines on off-centre be combined with press part and roll ring, roll ring and in circular cylinder, carry out linear motion, suck refrigerant and compress and discharge.

As shown in Figure 1, rotary compressor is made of following structure: stator 2 and rotor 3 that motor is installed in shell 9 inside that are filled with certain gauging; And be pressed into running shaft 4 at the center of its rotor 3; Below the stator 2 of motor and rotor 3, be provided with equilibrium block 5; Be provided with the press part that absorbs compression refrigerant in running shaft 4 lower ends.

Press part is made of following structure: with the circular cylinder 8 of suction pipe connection; Be fixed in the upper bearing 7 that is through with running shaft 4 on the inner peripheral surface of shell 9 simultaneously; Combine closely at the lower bearing 13 of the downside of cylinder 8; Cylinder 8 forms the compression volume 16 of compression refrigerant gas with upper bearing 7, lower bearing 13; With running shaft 4 is the center, and that carries out in cylinder 8 simultaneously that off-centre rotatablely moves rolls ring 12.The suction port of its cylinder 8 has connected by cutting ferrule and has been provided with the liquid-storage container (not shown) that prevents that liquid refrigerant from entering, and is provided with the output tube 10 of the high pressure refrigerator gas of output compressor section compression on shell 9.

After the existing closed rotary compressor that as above constitutes connected power supply, the rotor 3 of motor drove the rotating shaft 4 that is pressed in rotor 3 and together rotates.Along with the rotation of rotating shaft 4, the eccentric part 17 that rotating shaft 4 lower ends form and roll ring 23 rotations with eccentric part 17 combines will enter the refrigerant gas that compression volume 16 interior low-temperature low-pressure refrigerant gas compressions become High Temperature High Pressure through the suction port of cylinder 8.Export by valve member through as above process compressed refrigerant, export the inside of seal container to, outputing to the outside through the slit between rotor 3 and the stator 2 by output tube 10 afterwards by the through hole of baffler 6.

As shown in Figure 2, aforesaid rotary compressor, in the rotation that drives eccentric part 17 along with rotating shaft 4, the ring 13 that rolls that combines with eccentric part 17 also rotates, the rotation of rolling ring 13 promotes baffle plate 18 and moves back and forth in baffle plate groove 19, cavity separated into two parts with cylinder 8 reaches the compression to refrigeration agent.That is, roll ring 13 baffle plates 18 that whenever turn around and in baffle plate groove 19, move back and forth once, thereby finish compression process one time.

As shown in Figure 3, the baffle plate groove 19 and baffle plate 18 contacted two walls of existing compresser cylinder 8 are plane structures, and are same, and baffle plate 18 also is a plane structure with baffle plate groove 19 contacted two sides.In order to reduce the friction of baffle plate 18 and upper bearing (metal), prior art is to adopt to make baffle plate 18 tops exist the structure of certain distance to reduce friction to the cylinder top.But this structure has not only increased leakage, and because the vibration of baffle plate 18 in movement process will be clashed into upper bearing (metal), produces noise.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of and can reduce compresser cylinder and the baffle arrangement that leaks and vibrate the impact noise that is produced.

The technological scheme that the utility model adopted is: a kind of compresser cylinder and baffle arrangement, include compresser cylinder, center at cylinder is formed with compression volume, be formed with the baffle plate groove that communicates with compression volume on the cylinder wall, the embedding that can move back and forth in the baffle plate groove is useful on the baffle plate of compression volume being divided into breathing space and exhaust space, the bottom of baffle plate groove is provided with spring, spring is supported on an end of baffle plate, be formed with the teeth groove on two walls that described baffle plate groove contacts with baffle plate, and form on baffle plate and the baffle plate groove side surfaces contacted with baffle plate groove on the teeth groove corresponding and slidably embed teeth in it.Formed teeth groove is the symmetrical formation of two walls on two walls of described baffle plate groove.

Compresser cylinder of the present utility model and baffle arrangement, because the teeth groove and the teeth that between baffle plate groove and baffle plate, formed mutual correspondence, embed mutually, baffle plate moving back and forth in baffle plate groove is restricted, and reduced the distance that the baffle plate top exists to the cylinder top, thereby can reduce to leak the noise that reduces to vibrate generation.

Embodiment

As Fig. 2, shown in Figure 4, compresser cylinder of the present utility model and baffle arrangement, include compresser cylinder 28, be formed with compression volume 16 at the center of cylinder 28, be formed with the baffle plate groove 39 that communicates with compression volume 16 on the cylinder wall, the embedding that can move back and forth in the baffle plate groove 39 is useful on the baffle plate 38 of compression volume 16 being divided into breathing space and exhaust space.The bottom of baffle plate groove 39 is provided with spring, spring is supported on an end of baffle plate 38, and the ring 23 that rolls in the other end of baffle plate 38 and the cylinder contacts, when rolling under rolling ring 23 effect at running shaft, promote baffle plate 38 and reciprocatingly move, thereby compression volume 16 is divided into breathing space and exhaust space.

Be formed with teeth groove 40 on described baffle plate groove 39 and two walls that baffle plate 38 contacts, and form on baffle plate 38 and baffle plate groove 39 side surfaces contacted with baffle plate groove 39 on teeth groove 40 corresponding and slidably inlay within it teeth 42.Formed teeth groove 40 is the symmetrical formation of two walls on two walls of described baffle plate groove 39.

When the assembling cylinder, the baffle plate 38 that will have teeth 42 earlier is embedded in the baffle plate groove 39 that has teeth groove 40, in the compression volume 16 of cylinder, put into the ring that rolls that is enclosed within the eccentric shaft outside again, when rolling rolling compression volume 16 under ring 23 the effects at running shaft, when promotion baffle plate 38 reciprocatingly moves, baffle plate 38 moving back and forth in baffle plate groove 39 is restricted, be that baffle plate 38 can only laterally move in baffle plate groove 39, and can not do upper and lower moving, thereby can reduce to leak the noise that reduces to vibrate generation.
