Referring to fig. 1, 3 and 4, a horizontal compressor 100 provided in the present application will now be described. The horizontal compressor 100 includes a casing 10, a compression mechanism 30, a motor 20, a base 40, an intake pipe 61, and an exhaust pipe 50. Wherein:

Since the compression mechanism section 30 is provided in the casing 10, the intake pipe 61 passes through the casing 10 to be connected to the compression mechanism section 30.

The casing 10 is provided with an exhaust pipe 50 so that the refrigerant compressed by the compression mechanism 30 is discharged from the exhaust pipe 50 for use by external equipment, such as other devices of the cooling and heating equipment.

The cabinet 10 is provided with an exhaust guide 14 to be connected to the exhaust duct 50, thereby connecting the exhaust duct 50 to the cabinet 10. In the connection, one end of the exhaust pipe 50 is inserted into the exhaust guide 14, and the exhaust guide 14 is welded to the exhaust pipe 50.

Compared with the prior art, the application provides a horizontal compressor 100, through set up exhaust duct 14 on casing 10 to set up location structure 143 in exhaust duct 14, fix a position the degree of depth that exhaust pipe 50 inserted in casing 10, and then when exhaust pipe 50 and exhaust duct 14 welded, avoid the rosin joint, guarantee welded leakproofness, fastness and stability, avoid producing the welding and reveal, promote the security that this horizontal compressor 100 used.

In one embodiment, the exhaust guide 14 includes a first guide section 141 and a second guide section 142, and the inner diameter of the first guide section 141 is smaller than that of the second guide section 142, so that a positioning step is formed at the connection of the first guide section 141 and the second guide section 142, and when the exhaust pipe 50 is inserted into the second guide section 142, the positioning step at the connection of the first guide section 141 and the second guide section 142 stops the exhaust pipe 50 to position the exhaust pipe 50. That is, the positioning step formed between the first guide section 141 and the second guide section 142 is used as the positioning structure 143 in the exhaust guide pipe 14.

It will be appreciated that the positioning structure 143 may also be a raised structure provided in the exhaust conduit 14, for example, the raised structure may be a separately provided positioning collar to be fixed in the exhaust conduit 14, such that the exhaust pipe 50 is positioned by the positioning collar when the exhaust pipe 50 is inserted into the exhaust conduit 14. Of course, the protruding structure may also be a positioning bump, such as some positioning bumps may be provided in the exhaust conduit 14, through which the exhaust pipe 50 is positioned. In the case where the above-described positioning projecting ring or positioning projecting point is provided, the inner wall of the exhaust duct 14 may be a smooth structure without making a step. It is also possible to make a constriction in the exhaust gas duct 14, by means of which the exhaust gas pipe 50 is positioned.

When the straight pipe section 51 and the necking section 52 are inserted into the exhaust guide 14, the positioning structure 143 stops the positioning ring table 53 to position the depth of insertion of the exhaust pipe 50 into the exhaust guide 14; and the positioning structure 143 stops the peripheral side of the positioning ring table 53, it is possible to define the positioning ring table 53 in the middle of the exhaust guide 14, and further define the portion of the exhaust pipe 50 inserted into the exhaust guide 14 in the middle of the exhaust guide 14, so that the exhaust pipe 50 is connected to the exhaust guide 14 by welding well.

In the present embodiment, the stepped positioning structure 143 is formed between the first guide section 141 and the second guide section 142, the intersection of the necking section 52 and the straight pipe section 51 forms a positioning ring table 53, when the necking section 52 and the straight pipe section 51 are inserted into the exhaust duct 14, the necking section 52 is inserted into the first guide section 141, the straight pipe section 51 is inserted into the second guide section 142, and the positioning structure 143 supports the positioning ring table 53 in a matching manner, so as to position the exhaust duct 50. The structure is convenient to manufacture and stable in positioning. It is understood that the positioning structure 143 can also be a positioning bump to stop the positioning ring platform 53 for positioning. When the positioning structure 143 is a positioning collar, the neck section 52 passes through the positioning collar, and the positioning collar stops the positioning collar table 53 to perform a positioning function. In addition, when the portion of the exhaust pipe 50 inserted into the exhaust guide 14 is entirely a straight pipe, the positioning structure 143 may stop the end surface of the exhaust pipe 50 to serve to limit the depth of insertion of the exhaust pipe 50 into the exhaust guide 14.

When in use, the air inlet outer tube 612 is connected, so that the use is more convenient, and the air inlet outer tube 612 is prevented from being damaged in the transportation process. In addition, the air intake pipe 61 is divided into the air intake inner pipe 611 and the air intake outer pipe 612, so that the air intake inner pipe 611 can be better manufactured to connect the air intake inner pipe 611 with the compression mechanism portion 30, and the air intake inner pipe 611 is adapted to the air intake conduit 15 to ensure the sealing property, the connection firmness and the stability of the welding of the air intake inner pipe 611 and the air intake conduit 15.

In one embodiment, the end of the inner intake pipe 611 away from the compressing mechanism portion 30 has a flared section 6111, and due to the arrangement of the flared section 6111, a step is formed at the end of the flared section 6111 close to the compressing mechanism portion 30, and the step can be used as the above-mentioned limit structure 6112. Thus, when the one end of the air intake inner tube 611 is inserted into the flared section 6111, the step at the one end of the flared section 6111 close to the compression mechanism 30 serves as a limit structure 6112, so as to position the air intake inner tube 611. In addition, the flared section 6111 is arranged, so that the flared section 6111 can be better matched with the air inlet guide pipe 15, and the welding quality is ensured when the flared section 6111 is welded with the air inlet guide pipe 15.

The intake accumulator 60 is connected to one end of the intake pipe 61 remote from the compression mechanism portion 30, so as to supply refrigerant to the compression mechanism portion 30, that is, gaseous refrigerant separated from the intake accumulator 60, to the compression mechanism portion 30 through the intake pipe 61 for compression.

In one embodiment, referring to fig. 6 to 8, the horizontal compressor 100 further includes a gas injection pipe 71, and the gas injection pipe 71 passes through the casing 10 and is connected to the compression mechanism portion 30.

In one embodiment, the horizontal compressor 100 further includes a gas injection accumulator 70, the gas injection accumulator 70 is used for gas-liquid separation, that is, the refrigerant enters the gas injection accumulator 70 for gas-liquid separation, and the gaseous refrigerant enters the compression mechanism portion 30 to be compressed by the compression mechanism portion 30, so as to improve the compression efficiency of the compression mechanism portion 30. The gas ejection accumulator 70 is connected to one end of the gas ejection tube 71 remote from the compression mechanism section 30, and supplies refrigerant, that is, gaseous refrigerant separated from the gas ejection accumulator 70, to the compression mechanism section 30 through the gas ejection tube 71, and the refrigerant is compressed in the compression mechanism section 30.

The gas pressure of the refrigerant injected into the compression mechanism section 30 from the gas injection accumulator 70 is high. When the compression mechanism 30 is operated, the refrigerant flowing out of the intake accumulator 60 enters the compression mechanism 30 through the intake pipe 61 to be replenished, and the pressure of the refrigerant replenished in the compression mechanism 30 is low. Continuing to operate the compression mechanism 30, the compression mechanism 30 stops supplying air from the air inlet pipe 61; then, the refrigerant in the gas injection liquid storage device 70 is injected into the compression mechanism part 30 through the gas injection pipe 71, so that the air pressure in the compression mechanism part 30 is increased to realize gas supply and enthalpy increase, more refrigerant is injected into the compression mechanism part 30, the operation is continued in the compression mechanism part 30 to compress the refrigerant, and then the refrigerant with higher pressure can be generated, and the energy efficiency ratio is improved.

In one embodiment, referring to fig. 6 to 8, the injection liquid storage device 70 and the intake liquid storage device 60 are respectively disposed on two opposite sides of the casing 10, so as to avoid the increase of the height of the horizontal compressor 100 caused by the arrangement of the injection liquid storage device 70 and the intake liquid storage device 60, and further ensure that the height of the enhanced vapor injection compressor is small, so as to facilitate the use in the places or occasions with large high pressure restrictions, such as vehicles.

The air injection reservoir 70 and the air intake reservoir 60 are respectively arranged at two opposite sides of the casing 10, so that the vibration of the compression mechanism part 30 in the casing 10 can be better prevented from being transmitted to the air injection reservoir 70 and the air intake reservoir 60, the vibration of the air injection reservoir 70 and the air intake reservoir 60 is reduced, fatigue aging caused by vibration in the connection between the air intake pipe 61 and the air intake reservoir 60 is avoided, and the stability in the connection between the air intake pipe 61 and the air intake reservoir 60 is ensured; in the same way, fatigue and aging caused by vibration of the connection between the gas injection pipe 71 and the gas injection liquid storage device 70 can be avoided, and the stability of the connection between the gas injection pipe 71 and the gas injection liquid storage device 70 is ensured.

The air injection reservoir 70 and the air intake reservoir 60 are respectively arranged at two opposite sides of the machine shell 10, so that the overall weight of the machine shell 10 can be reduced, resonance between the air injection reservoir 70 and the air intake reservoir 60 and the machine shell 10 is avoided, and the vibration transmission of the air injection reservoir 70 and the air intake reservoir 60 to the machine shell 10 and the compression mechanism part 30 can be reduced, so that the vibration of the machine shell 10 and the compression mechanism part 30 is reduced, and the compression mechanism part 30 can run more stably; and also can ensure the stability of the connection of the air inlet pipe 61 and the air injection pipe 71 with the casing 10. Since the vibration of the cabinet 10 can be reduced due to this structure, the vibration of the exhaust duct 50 can be reduced to ensure a more stable connection of the exhaust duct 50 with the cabinet 10.

Referring to fig. 9, an end of the air inlet pipe 61 close to the compressing mechanism portion 30, that is, an end of the air inlet pipe 61 close to the casing 10, an end of the air inlet pipe 61 connected to the compressing mechanism portion 30, and an end of the air inlet pipe 61 far from the air inlet reservoir 60 are illustrated. Since the air intake passage 313 in the compression mechanism section 30 is generally provided adjacent to the slide plate 33, the air intake pipe 61 is provided adjacent to the base 40 at the end close to the compression mechanism section 30, the slide plate 33 in the compression mechanism section 30 can be immersed in the oil sump at the lower side portion of the casing 10, and there is no need to provide a complicated air intake structure in the compression mechanism section 30 and a complicated air intake passage in the casing 10, so that the air intake structure can be simplified.

The end of the air injection pipe 71 close to the compression mechanism portion 30 is actually the end of the air injection pipe 71 close to the casing 10, and is also the end of the air injection pipe 71 connected to the compression mechanism portion 30, and is the end of the air injection pipe 71 far from the air injection reservoir 70. Since the gas injection passage and the gas intake passage 313 in the compression mechanism section 30 are located on both sides of the slide vane 33, and the gas injection passage in the compression mechanism section 30 is disposed adjacent to the slide vane 33, the gas injection time is longer, more refrigerant enters the compression mechanism section 30, and the energy efficiency ratio is higher. The end of the air injection pipe 71 close to the compression mechanism part 30 is arranged close to the base 40, so that the sliding sheet 33 in the compression mechanism part 30 can be ensured to be immersed into an oil pool at the lower side part of the machine shell 10, and the air injection channel in the compression mechanism part 30 is arranged closer to the sliding sheet 33, so that the air injection pipe 71 can be directly connected with the compression mechanism part 30 on the premise of ensuring the good energy efficiency ratio of the compression mechanism part 30, a complex air injection structure does not need to be arranged in the compression mechanism part 30, a complex air injection passage does not need to be arranged in the machine shell 10, and the air injection structure can be simplified.

The air injection reservoir 70 and the air inlet reservoir 60 are respectively arranged at two opposite sides of the machine shell 10, the corresponding air injection pipe 71 and the air inlet pipe 61 are respectively positioned at two sides of the base 40, thus after the sliding sheet 33 in the compressing mechanism part 30 is immersed in an oil pool at the lower side part of the machine shell 10, the space at the position of the base 40 can be more fully utilized, so that the distance between one end of the air injection pipe 71 close to the compressing mechanism part 30 and one end of the air inlet pipe 61 close to the compressing mechanism part 30 is closer, the connection of the air injection pipe 71 and the air inlet pipe 61 with the machine shell 10 is convenient, the structure of the compressing mechanism part 30 is simplified, the manufacturability of the horizontal compressor 100 is improved, and the air injection amount is ensured.

In addition, the one end that jet tube 71 is close to compressing mechanism portion 30 and the one end that intake pipe 61 is close to compressing mechanism portion 30 are close to base 40 and set up, and base 40 fixes casing 10, because the fixed action of base 40, the position vibration that is close to base 40 on the casing 10 can be littleer, can make the vibration of jet tube 71 and intake pipe 61 littleer like this, in order to avoid jet tube 71 and intake pipe 61 to be connected because of the vibration fatigue aging with casing 10, guarantee that jet tube 71 and intake pipe 61 are more stable with being connected of casing 10, and then guarantee the good operation of this horizontal compressor 100, promote the life-span of this horizontal compressor 100.

In an embodiment, referring to fig. 6, 8 and 9, when the horizontal compressor 100 is an enhanced vapor injection compressor, the cylinder 31 is further provided with an injection passage 315, the injection passage 315 is communicated with the working chamber 311, and the injection passage 315 is connected to the injection pipe 71, so that the refrigerant in the injection pipe 71 can be injected into the working chamber 311 from the injection passage 315 to supplement air and increase enthalpy, increase the amount of the refrigerant in the working chamber 311, and be compressed by the piston 32 to improve the energy efficiency ratio. In addition, the air injection channel 315 is arranged on the air cylinder 31, so that the structure is simple, and the processing and the manufacturing are convenient.

The air injection passage 315 and the air intake passage 313 are respectively arranged at two sides of the slide channel groove 312, and the exhaust passage 314 is arranged between the air injection passage 315 and the slide channel groove 312, so that the longer air injection time can be ensured, the air injection amount can be ensured, and the energy efficiency ratio can be improved.

One operation of the piston 32 to compress refrigerant is as follows: the piston 32 rolls in the working chamber 311 of the cylinder 31, and the piston 32 rolls from the inlet passage 313 toward the outlet passage 314, and in this process, a space defined between the piston 32 and the inner surface of the working chamber 311 of the cylinder 31 and the vane 33 changes from small to large, and the refrigerant enters the working chamber 311 from the inlet passage 313. After the piston 32 rolls through the air inlet channel 313, the refrigerant entering the working cavity 311 flows along with the piston 32 towards the direction of the air outlet channel 314; the gas injection passage 315 injects the refrigerant into the working chamber 311 to increase the amount and pressure of the refrigerant in the working chamber 311. When sufficient refrigerant is injected into the working chamber 311, the gas injection passage 315 is closed, and the piston 32 rolls through the gas injection passage 315 to compress the refrigerant and discharge the refrigerant from the discharge passage 314. Because the air injection passage 315 injects the refrigerant with higher pressure, the amount of the refrigerant extruded by the piston 32 can be increased, and the pressure of the discharged refrigerant can be increased, so that the energy efficiency ratio is improved, and the air-supplying and enthalpy-increasing are realized.

In the embodiment, the air injection passage 315 and the air intake passage 313 are directly manufactured on the air cylinder 31, and compared with the structure of manufacturing passages on the cover plate of the air cylinder 31 at present, the structure of the embodiment is simpler, the processing and manufacturing are convenient, and the manufacturing cost is low; and the compression mechanism part 30 can be ensured to operate more stably due to the reduction of structural components and the reduction of complexity.

In an embodiment, referring to fig. 7, 8 and 9, the air injection passage 315 is disposed along the radial direction of the air cylinder 31, so as to simplify the structure of the air injection passage 315, facilitate the manufacturing process, simplify the manufacturing difficulty of the air cylinder 31, reduce the manufacturing difficulty and cost of the compression mechanism 30, and facilitate the layout of the position of the air injection passage 315.

In an embodiment, referring to fig. 7, 8 and 9, the air inlet channel 313 extends along the radial direction of the cylinder 31, so that the structure of the air inlet channel 313 can be simplified, the processing and manufacturing are convenient, the manufacturing difficulty of the cylinder 31 is also simplified, and the manufacturing difficulty and cost of the compression mechanism 30 are reduced.

In one embodiment, the angle R between the axial direction of the air injection passage 315 and the axial direction of the air intake passage 313 is in the range of 90-135 degrees, for example, the angle R between the axial direction of the air injection passage 315 and the axial direction of the air intake passage 313 may be 90 degrees, 92 degrees, 95 degrees, 98 degrees, 100 degrees, 102 degrees, 105 degrees, 108 degrees, 110 degrees, 112 degrees, 115 degrees, 118 degrees, 120 degrees, 122 degrees, 125 degrees, 128 degrees, 130 degrees, 132 degrees, 135 degrees, and the like.

The range of the included angle R between the axial direction of the air injection channel 315 and the axial direction of the air inlet channel 313 is set to 90-135 degrees, so that sufficient air injection amount can be ensured, the horizontal compressor 100 has a high energy efficiency ratio, the manufacturing is convenient, the layout and the installation of the air inlet pipe 61 and the air injection pipe 71 are convenient, the air injection channel 315 and the air injection pipe 71 are convenient to connect, the air inlet channel 313 and the air inlet pipe 61 are convenient to connect, and the manufacturability of the horizontal compressor 100 is improved.

When the angle R between the axial direction of the air injection passage 315 and the axial direction of the air intake passage 313 is smaller than 90 degrees, the air injection passage 315 and the air intake passage 313 are too close to each other, which may cause the air intake pipe 61 and the air injection pipe 71 to be too close to each other, making installation difficult and manufacturing poor. When the included angle R between the axial direction of the air injection passage 315 and the axial direction of the air intake passage 313 is greater than 135 degrees, the distance between the air injection passage 315 and the air intake passage 313 is too large, which may shorten the air injection time, resulting in insufficient air injection amount, and thus deteriorating the energy efficiency ratio of the horizontal compressor 100.

In one embodiment, the jet reservoir 70 is welded to the base 40 to ensure that the jet reservoir 70 is securely attached to the base 40. Because the jet accumulator 70 is welded and fixed with the base 40, and when the horizontal compressor 100 is used, the base 40 is fixedly connected with the medium surface, so that the vibration of the base 40 is smaller, the vibration of the corresponding jet accumulator 70 is also smaller, and the vibration of the horizontal compressor 100 during operation can be further reduced. In addition, because the air pressure of the refrigerant in the jet accumulator 70 is higher, vibration is more easily generated when the refrigerant flows, and the jet accumulator 70 and the base 40 are welded and fixed, so that the vibration generated by the flowing of the refrigerant can be better absorbed, and the vibration of the jet accumulator 70 is reduced. It will be appreciated that the jet reservoir 70 can be fixedly attached to the base 40 using other fasteners, such as by tying the jet reservoir 70 to the base 40.

In one embodiment, the jet accumulator 70 is extended along the length direction of the casing 10, and the jet accumulator 70 is disposed horizontally, so as to ensure that the jet accumulator 70 does not exceed the height of the casing 10, so as to make the height of the horizontal compressor 100 smaller. In addition, the structure can also set the height of the air injection reservoir 70 to be lower so as to conveniently connect the air injection reservoir 70 and the base 40 in a welding and fixing way.
