In addition, it will be appreciated by those skilled in the art that the compressor 800 may include a driving motor for driving the cylinder assembly 802 in addition to the housing 801 and the cylinder assembly 802. As shown in fig. 1-3, the cylinder assembly 802 includes: a medium pressure chamber 10, a first cylinder 1, a second cylinder 2, a valve body 3 and a driving member (not shown). Wherein, the medium pressure chamber 10 is connected with the flash vessel 600, for example, a partition plate may be disposed between the first cylinder 1 and the second cylinder 2, the medium pressure chamber 10 may be formed on the partition plate, and a gas passage communicating the flash vessel 600 with the medium pressure chamber 10 is further formed on the partition plate. Of course, the present invention is not limited thereto, and the intermediate pressure chamber 10 may not be provided on a partition, for example, the intermediate pressure chamber 10 may be formed on a separate auxiliary member provided outside the first cylinder 1 and the second cylinder 2, without limitation.
As shown in fig. 2, the first cylinder 1 is provided with a first sliding vane groove 12, air suction holes 13 and a cylindrical cavity 14 which are positioned at two sides of the first sliding vane groove 12, the air suction holes 13 are communicated with a liquid storage 700, the second cylinder 2 is provided with a second sliding vane groove 22, air inlet holes 23 and air outlet holes 24 which are positioned at two sides of the second sliding vane groove 22, the air inlet holes 23 are communicated with the medium-pressure cavity 10, and the air outlet holes 24 are communicated with the inside of the shell 801.
For example, in the specific example shown in fig. 1 and 2, the first cylinder 1 is provided with a first cylinder chamber 11, the first cylinder chamber 11 and the first vane groove 12 may penetrate the first cylinder 1 in the axial direction of the first cylinder 1, the first vane groove 12 extends in the radial direction of the first cylinder chamber 11, a first piston (not shown) eccentrically rolling in the first cylinder chamber 11 is provided, a first vane (not shown) reciprocally moving in the extending direction of the first vane groove 12 is provided in the first vane groove 12, the tip of the first vane is stopped against the first piston to partition the first cylinder chamber 11 into a first suction chamber and a first compression chamber together with the first piston, the suction hole 13 and the cylindrical chamber 14 are provided on both sides in the width direction of the first vane groove 12, respectively, and the suction hole 13 communicates with the reservoir 700 on the one hand, and communicates with the first suction chamber on the other hand, and the cylindrical chamber 14 communicates with the first compression chamber. Thus, when the first piston rolls in the first cylinder chamber 11, the refrigerant in the accumulator 700 can be sucked into the first suction chamber through the suction hole 13, and the refrigerant in the first compression chamber is compressed and discharged into the cylinder chamber 14.
For example, in the specific example shown in fig. 1 and 2, the second cylinder 2 is provided with a second cylinder chamber 21, the second cylinder chamber 21 and the second vane groove 22 may penetrate the second cylinder 2 in the axial direction of the second cylinder 2, and the second vane groove 22 extends in the radial direction of the second cylinder chamber 21, wherein a second piston (not shown) that eccentrically rolls is provided in the second cylinder chamber 21, a second vane (not shown) that reciprocates in the extending direction of the second vane groove 22 is provided in the second vane groove 22, the tip end of the second vane is stopped against the second piston to partition the second cylinder chamber 21 into a second suction chamber and a second compression chamber together with the second piston, an intake hole 23 and an exhaust hole 24 are provided on both sides in the width direction of the second vane groove 22, respectively, and the intake hole 23 communicates with the medium pressure chamber 10 on the one hand, the second suction chamber on the other hand, and the exhaust hole 24 communicates with the inside of the casing 801 on the other hand, and the second compression chamber. Thus, when the second piston rolls in the second cylinder chamber 21, the refrigerant in the intermediate pressure chamber 10 can be sucked into the second suction chamber through the air inlet hole 23, and the refrigerant in the second compression chamber is compressed and discharged into the housing 801 through the air discharge hole 24.
Referring to fig. 2 to 7, the cylindrical chamber 14 (not limited to the cylindrical chamber, for example, may be a polygonal cylindrical chamber, etc.) may be penetrated through and penetrate at least one of both axial side end surfaces of the first cylinder 1 in the axial direction of the first cylinder 1, and the cylindrical chamber 14 has a communication hole 141 on a peripheral wall thereof, a first through hole 142, and a second through hole 143, wherein the communication hole 141 communicates with the cylinder chamber of the first cylinder 1 (i.e., the above-mentioned first cylinder chamber 11), the first through hole 142 communicates with the medium pressure chamber 10, the second through hole 143 communicates with the inside of the case 801, the valve body 3 is provided in the cylindrical chamber 14 and includes a cylinder 31 (the cylinder 31 may be coaxially arranged with the cylindrical chamber 14 or slightly off-axis) and a stopper 32 and a valve plate 33 provided on an outer peripheral wall of the cylinder 31, and the driving member is connected with the valve body 3 to drive the valve body 3 to rotate between a first position (as shown in fig. 2 and 3) where the communication hole 141 is covered by the stopper 33 and a second position (as shown in fig. 2 and 3) where the communication hole 141 is covered by the stopper 32 and the second through hole 143 is blocked by the valve plate 32 (as shown in fig. 4 and 5). Here, it will be appreciated that the driving member serves to drive the rotation of the valve body 3, and thus there are many alternative driving members, for example, the driving member may be a motor or a gear assembly, etc., and thus is not limited.
As shown in fig. 2 and 3, when the driving member drives the valve body 3 to rotate to the first position, the valve plate 33 is opposite to the communication hole 141 to control the opening and closing of the communication hole 141, the blocking member 32 is opposite to the first through hole 142 to close the first through hole 142, and the second through hole 143 is in an open state, at this time, when the pressure of the refrigerant in the first compression chamber is greater than the discharge pressure, the compressed refrigerant can push the valve plate 33 open and flow into the gap between the cylinder 31 and the cylinder chamber 14 through the communication hole 141, and then is discharged into the housing 801 through the opened second through hole 143, at this time, the air inlet 23 can also suck the refrigerant from the flash tank 600 through the medium pressure chamber 10 and discharge the compressed refrigerant into the housing 801 through the discharge hole 24, thereby realizing independent single stage compression of the two cylinders.
As shown in fig. 4 and 5, when the driving member drives the valve body 3 to rotate to the second position, the valve plate 33 is opposite to the communication hole 141 to control the opening and closing of the communication hole 141, the blocking member 32 is opposite to the second communication hole 143 to close the second communication hole 143, the first through hole 142 is in an open state, at this time, when the pressure of the refrigerant in the first compression chamber is greater than the discharge pressure, the compressed refrigerant can push the valve plate 33 open and flow through the communication hole 141 into the gap between the cylinder 31 and the cylinder chamber 14, and then is discharged into the medium pressure chamber 10 through the open first through hole 142 to be mixed with the refrigerant entering the medium pressure chamber 10 from the flash device 600, at this time, the air inlet 23 can suck the mixed refrigerant through the medium pressure chamber 10 and discharge the compressed refrigerant into the inside of the housing 801 through the discharge hole 24, thereby realizing the two-stage compression associated with the two cylinders.
Thus, according to the compressor 800 of the embodiment of the present invention, by providing the cylindrical cavity 14 and the valve body 3 on the first cylinder 1, the communication between the cylindrical cavity 14 and the medium pressure cavity 10 and the inside of the housing 801 is switched by the rotation of the valve body 3, so that the purposes of independent compression and two-stage compression coupling can be achieved, and the working efficiency is high. In short, the present control method is simple and effective, and the compressor 800 has a simple structure and low cost.
In some embodiments of the present invention, as shown in fig. 7, the valve sheet 33 includes a first sub-valve sheet 331 and a second sub-valve sheet 332 provided at both circumferential sides of the stopper 32 and extending in the axial direction of the cylinder 31, at least one of the axial ends of the valve sheet 33 being shorter than the corresponding at least one of the axial ends of the cylinder 31, that is, at least one of the axial ends of the first sub-valve sheet 331 being shorter than the corresponding at least one of the ends of the cylinder 31, and at least one of the axial ends of the second sub-valve sheet 332 being shorter than the corresponding at least one of the ends of the cylinder 31. For example, in the specific example shown in fig. 7, the axis of the column 31 extends in the up-down direction, the first sub-valve plate 331 and the second sub-valve plate 332 are each formed as a sheet body extending in the up-down direction, the upper end of the first sub-valve plate 331 and the upper end of the second sub-valve plate 332 are each flush with the upper end face of the column 31, and the lower end of the first sub-valve plate 331 and the lower end of the second sub-valve plate 332 are each shorter than the lower end of the column 31 (i.e., located above the lower end face of the column 31).
As shown in fig. 3, 5 and 7, the fixed ends of the first sub-valve plate 331 and the second sub-valve plate 332 are both close to the stopper 32, and the free ends are both far away from the stopper 32, and when the valve body 3 rotates to the first position, the free ends of the first sub-valve plate 331 cover the communication hole 141, and at this time, the communication hole 141 is controlled to open and close by the first sub-valve plate 331, and when the valve body 3 rotates to the second position, the free ends of the second sub-valve plate 332 cover the communication hole 141, and at this time, the communication hole 141 is controlled to open and close by the second sub-valve plate 332. Thus, the valve plate 33 has a simple structure, and the manner of controlling the independent compression and the two-stage compression switching is simple and reliable.
Specifically, as shown in fig. 2, 3, 6 and 7, when the valve body 3 is rotated to the first position, if the pressure of the refrigerant in the first cylinder chamber 11 is greater than the discharge pressure, the high-pressure refrigerant in the communication hole 141 may push the free end of the first sub-valve plate 331 to move toward the direction approaching the cylinder 31 so that the port where the communication hole 141 communicates with the cylinder chamber 14 is opened, at this time, the high-pressure refrigerant may enter the gas chamber a defined by the cylinder chamber 14, the first sub-valve plate 331, the second sub-valve plate 332 and the cylinder 31 through the communication hole 141, then flow downward into the gas chamber B defined by the cylinder chamber 14 and the cylinder 31 below the first sub-valve plate 331 and the second sub-valve plate 332, and then bypass the lower end of the second sub-valve plate 332, flow upward into the gas chamber C defined by the second sub-valve plate 332 and the cylinder chamber 14, and thus may be discharged into the inside of the housing 801 through the second through hole 143.
Specifically, as shown in fig. 4, 5, 6 and 7, when the valve body 3 is rotated to the second position, if the pressure of the refrigerant in the first cylinder chamber 11 is greater than the discharge pressure, the high-pressure refrigerant in the communication hole 141 may push the free end of the second sub-valve plate 332 to move toward the direction approaching the cylinder 31 so that the port where the communication hole 141 communicates with the cylinder chamber 14 is opened, at this time, the high-pressure refrigerant may enter the gas chamber D defined by the cylinder chamber 14, the second sub-valve plate 332, the first sub-valve plate 331 and the cylinder 31 through the communication hole 141, then flow downward into the gas chamber B defined by the cylinder chamber 14 and the cylinder 31 below the first sub-valve plate 331, and the second sub-valve plate 332, and then bypass the lower end of the first sub-valve plate 331, flow upward into the gas chamber E defined by the space between the first sub-valve plate 331 and the cylinder chamber 14, and may be discharged into the medium pressure chamber 10 through the first through hole 142.
Preferably, both ends of the first sub-valve sheet 331 and both ends of the second sub-valve sheet 332 are shorter than the respective ends of the cylinder 31 (this example is not shown). That is, the upper end of the first sub-valve plate 331 and the upper end of the second sub-valve plate 332 are lower than the upper end surface of the column 31, and the lower end of the first sub-valve plate 331 and the lower end of the second sub-valve plate 332 are higher than the lower end surface of the column 31. Thus, the air flow entering the air chamber a can flow downwards and upwards respectively and then enter the air chamber C, and the air flow entering the air chamber D can flow downwards and upwards respectively and then enter the air chamber E, so that the discharge speed of the refrigerant is increased and the performance of the compressor 800 is improved.
In some alternative embodiments of the present invention, as shown in fig. 6 and 8, the communication holes 141 are plural and spaced apart in the axial direction of the first cylinder 1, and the first sub-valve plate 331 and the second sub-valve plate 332 each include plural tentacles 330 disposed spaced apart in the axial direction of the cylinder 31 and for covering the plural communication holes 141 correspondingly. Therefore, when the valve body 3 rotates to the first position, the plurality of tentacles 330 on the first sub-valve plate 331 control the opening and closing of the plurality of communication holes 141 in a one-to-one correspondence manner, and when the valve body 3 rotates to the second position, the plurality of tentacles 330 on the second sub-valve plate 332 control the opening and closing of the plurality of communication holes 141 in a one-to-one correspondence manner, thereby improving the smoothness of exhaust and further improving the reliability of controlling independent compression and double-stage compression switching. Here, it is understood that when the first and second sub-valve plates 331 and 332 respectively constitute the continuous sheet shape shown in fig. 7, the opening and closing of the plurality of communication holes 141 may also be controlled.
In addition, it should be noted that, the structure of the valve plate 33 is not limited to this, for example, in the specific example shown in fig. 9, the valve plate 33 may further include two sets of valve plates 33, each set of valve plates 33 may also be a plurality of small valve plates 333 independently mounted on the column 31, and each small valve plate 333 controls the switch of a corresponding communication hole 141, so that the above technical effects can be achieved as well. And will not be described in detail here.
In some embodiments of the present invention, as shown in fig. 7 and 8, the fixed end of the first sub-valve plate 331 and the fixed end of the second sub-valve plate 332 are both connected to the blocking member 32, that is, the first sub-valve plate 331 and the second sub-valve plate 332 may be both fixed on the blocking member 32, thereby facilitating installation and having good control effect of the valve plate 33. Of course, the present invention is not limited thereto, and the first and second sub-valve plates 331 and 332 may be mounted on the column 31.
In some embodiments of the present invention, the first through hole 142 and the second through hole 143 may each be plural and spaced apart in the axial direction of the first cylinder 1 (for example, up-down direction shown in fig. 6) (not shown). Thereby, the structural strength of the first cylinder 1 is higher. At this time, it is preferable that the stopper 32 includes a plurality of stoppers (not shown) provided at intervals in the axial direction of the cylinder 31 (for example, up-down direction shown in fig. 7), that is, each adjacent two stoppers are not connected, and the plurality of stoppers block the plurality of first through holes, respectively, when the valve body 3 is rotated to the first position, and block the plurality of second through holes, respectively, when the valve body 3 is rotated to the second position. Thereby, the cost can be reduced.
Of course, the present invention is not limited thereto, and as shown in fig. 7 to 9, the stopper 32 may be a stopper 320 extending along an axial direction of the column 31 (for example, up-down direction shown in fig. 7), that is, the stopper 320 is an elongated structure extending from top to bottom, and has no broken position, and the stopper 320 simultaneously shields the plurality of first through holes when the valve body 3 rotates to the first position, and the stopper 320 simultaneously shields the plurality of second through holes when the valve body 3 rotates to the second position. Thus, the processing is convenient. Moreover, when the first through hole 142 and the second through hole 143 are elongated through holes extending from top to bottom as shown in fig. 6, the stopper 320 can also effectively block and close them.
As shown in fig. 7 to 9, the width of the stopper 320 gradually increases in a direction away from the column 31. That is, the fixed end of the stopper 320 is connected to the cylinder 31, and the free end of the stopper 320 extends in a direction away from the cylinder 31, wherein the width of the fixed end of the stopper 320 is smaller than the width of the free end of the stopper 320 in the cross section of the valve body 3, and the width of the stopper 320 is gradually increased in a direction from the fixed end of the stopper 320 to the free end of the stopper 320, whereby the volumes of the gas chamber C and the gas chamber E can be increased, the exhaust efficiency can be improved, and the reliability of closing the first and second through holes 142 and 143 by the stopper 320 can be improved, and the cost can be reduced. Preferably, the stopper 320 is integrally formed with the cylinder 31, thereby facilitating processing.
In some preferred embodiments of the present invention, as shown in fig. 7 to 9, the valve body 3 is of axisymmetric structure, i.e., the valve body 3 is symmetric about a certain plane passing through the axis thereof, whereby the valve body 3 is simple in structure, easy to process, and highly reliable in operation.
In some preferred embodiments of the invention, two limiting members (not shown, such as stops, ribs, etc.) are provided on the inner wall of the cylindrical cavity 14 at intervals in the circumferential direction, and are in limiting engagement (e.g. in a stop engagement) with the two limiting members when the valve body 3 is moved to the first position and the second position, respectively. For example, the two limiting members are a first limiting member and a second limiting member respectively, when the valve body 3 rotates to the first position, one side wall of the blocking member 32 of the valve body 3 is stopped against the first limiting member, and when the valve body 3 rotates to the second position, the other side wall of the blocking member 32 of the valve body 3 is stopped against the second limiting member, so that the control difficulty can be reduced, and the indexing accuracy of the valve body 3 can be improved.
In addition, it should be noted that the column 31 according to the present invention is not limited to a cylindrical shape, and may be, for example, a polygonal column shape or the like. In addition, it should be noted that, according to some embodiments of the present invention, the air intake hole 13, the air intake hole 23, and the air exhaust hole 24 are not limited to simple air hole shapes, and may be, for example, all processed into a cavity form similar to the cylindrical cavity 14, and a valve member similar to the valve body 3 is disposed in the cavity, so as to achieve the effect of controlling air intake and air exhaust, which is not described herein again.
