Conventionally, a scroll compressor for compressing a refrigerant is known (for example, patent document 1).
The scroll compressor described in patent document 1 includes a compression mechanism, a motor that drives an orbiting scroll, a drive shaft that couples the orbiting scroll and the motor, a floating member that presses the orbiting scroll against a fixed scroll, and a casing that supports the floating member. A1 st chamber (2 nd space) into which an intermediate pressure is introduced, a2 nd chamber (1 st space) into which a high pressure is introduced, and a seal groove (3 rd annular groove) are provided between the floating member and the housing. The 2 nd chamber is provided inside the seal groove. The seal groove is provided with a seal member for partitioning the 1 st chamber and the 2 nd chamber.

Patent document 1: japanese patent laid-open publication No. 2018-035749
However, in order to provide the seal member, the width of the seal groove is required. As described above, when the introduction hole is provided at a position inside the seal groove, it is necessary to secure a region for providing a high-pressure flow path at a position inside the seal groove. This requires increasing the outer diameter of the seal member (seal groove), and therefore, the 2 nd chamber located inside the seal groove may increase accordingly. Further, when the 2 nd chamber becomes large, the floating member is pressed too much by the high pressure introduced into the 2 nd chamber, and thus, the performance of the scroll compressor may be degraded.

A scroll compressor 1 according to an embodiment of the present invention will be described with reference to fig. 1. Fig. 1 is a sectional view of a scroll compressor 1 according to an embodiment of the present invention.
The scroll compressor 1 is a low-pressure dome type scroll compressor. The scroll compressor 1 is applied to a refrigeration apparatus, for example. The refrigeration apparatus includes an air conditioning apparatus that adjusts the temperature and humidity of air, a cooling apparatus that cools the interior of the refrigerator, and a hot water supply apparatus that generates hot water. The scroll compressor 1 is provided in a refrigerant circuit (not shown) of a vapor compression refrigeration cycle, and compresses a refrigerant as a working fluid. In the refrigerant circuit, the refrigerant compressed in the scroll compressor 1 is condensed in the condenser, reduced in pressure in the pressure reducing mechanism, evaporated in the evaporator, and sucked into the scroll compressor 1.
As shown in fig. 1, the scroll compressor 1 has a casing 10, a compression mechanism 20, a motor 30, a drive shaft 40, a floating member 50, and a frame 60.
The casing 10 is formed in a longitudinal cylindrical shape with both ends closed. The compression mechanism 20, the motor 30, the drive shaft 40, the floating member 50, and the frame 60 are accommodated in the casing 10. The compression mechanism 20 and the motor 30 are coupled by a drive shaft 40. The drive shaft 40 extends in the axial direction Y of the scroll compressor 1. The axial direction Y of the scroll compressor 1 indicates the direction in which the drive shaft 40 extends. In the present embodiment, the axial direction Y of the scroll compressor 1 indicates the vertical direction.
A partition member 11 is provided at an upper portion in the casing 10. The partition member 11 partitions the inner space of the cabinet 10 into 2 spaces. The space above the partition member 11 constitutes the 1 st cabinet space S1. The space below the partition member 11 constitutes a2 nd cabinet space S2.
The casing 10 is provided with a suction pipe (not shown) and a discharge pipe 12. The suction pipe penetrates the main body of the casing 10 in the radial direction X and communicates with the 2 nd casing space S2. The suction pipe introduces a low-pressure fluid (e.g., a gas refrigerant) into the 2 nd cabinet space S2. The discharge pipe 12 penetrates the upper portion of the casing 10 in the radial direction X and communicates with the 1 st casing space S1. The discharge pipe 12 discharges the high-pressure fluid in the 1 st casing space S1 to the outside of the casing 10. The radial direction X represents a direction perpendicular to the axial direction Y.
The compression mechanism 20 draws in fluid and compresses it. The compression mechanism 20 includes a fixed scroll 21 and a movable scroll 26. The fixed scroll 21 is fixed to the frame 60. The orbiting scroll 26 is disposed between the floating member 50 and the fixed scroll 21. The orbiting scroll 26 is engaged with the fixed scroll 21 and eccentrically revolves with respect to the fixed scroll 21.
The fixed scroll 21 is disposed on one side (upper side in this example) in the axial direction Y of the scroll compressor 1. The fixed scroll 21 has a fixed-side end plate 22, a fixed-side wrap 23, and an outer peripheral wall portion 24.
The stationary-side end plate 22 is formed in a substantially circular plate shape. The fixed wrap 23 is formed in a wrap wall shape that describes an involute curve, and protrudes from a front surface (lower surface in this example) of the fixed end plate 22. Outer circumferential wall 24 is formed to surround the outer circumferential side of stationary wrap 23 and projects from the front surface of stationary end plate 22. The tip end surface (lower end surface in this example) of the fixed wrap 23 and the tip end surface of the outer circumferential wall 24 are substantially flush with each other.
A suction port (not shown) is formed in the outer peripheral wall 24 of the fixed scroll 21. The suction port communicates with the 2 nd cabinet space S2. A discharge port 25 penetrating the fixed end plate 22 in the thickness direction is formed in the center of the fixed end plate 22 of the fixed scroll 21.
The orbiting scroll 26 has an orbiting side end plate 27, an orbiting side wrap 28, and a hub portion 29.
The movable-side end plate 27 is formed in a substantially circular plate shape. The orbiting wrap 28 is formed in a wrap wall shape that describes an involute curve, and a front surface (upper surface in this example) of the driven-side end plate 27 protrudes. The boss portion 29 is formed in a cylindrical shape and is disposed in a central portion of a rear surface (a lower surface in this example) of the movable-side end plate 27. The orbiting wrap 28 of the orbiting scroll 26 meshes with the stationary wrap 23 of the stationary scroll 21.
With this structure, a compression chamber S20 is formed between the fixed scroll 21 and the orbiting scroll 26. The compression chamber S20 is a space for compressing the fluid. The compression chamber S20 is configured to compress the fluid sucked through the suction pipe, the 2 nd casing space S2, and the suction port, and to discharge the compressed fluid through the discharge port 25.
The motor 30 is housed in the casing 10 and disposed below the compression mechanism 20. The motor 30 has a stator 31 and a rotor 32. The stator 31 is formed in a substantially cylindrical shape and fixed to the housing 10. The rotor 32 is inserted through the inner periphery of the stator 31 so as to be rotatable. A drive shaft 40 is inserted through and fixed to the inner periphery of the rotor 32.
The drive shaft 40 drives the orbiting scroll 26. The drive shaft 40 is coupled to the orbiting scroll 26 and rotatably supports the orbiting scroll 26. The drive shaft 40 has a main shaft portion 41 and an eccentric shaft portion 42. The main shaft portion 41 extends in the axial direction Y of the scroll compressor 1. The eccentric shaft portion 42 is provided at the upper end of the main shaft portion 41. The outer diameter of the eccentric shaft portion 42 is smaller than the outer diameter of the main shaft portion 41. The axis of the eccentric shaft 42 is eccentric by a predetermined distance from the axis of the main shaft 41.
The floating member 50 presses the orbiting scroll 26 against the fixed scroll 21. The floating member 50 is formed substantially in a cylindrical shape. The float member 50 includes a scroll support portion 51, a bearing portion 53, and a coupling portion 55.
The scroll support portion 51 is a substantially cylindrical portion that contacts the back surface of the orbiting scroll 26. The scroll support portion 51 supports the orbiting scroll 26. A1 st annular groove 52 for accommodating an O-ring is formed near a lower end of the outer wall of the scroll support portion 51.
The bearing portion 53 rotatably supports the drive shaft 40. Bearing portion 53 is a substantially cylindrical portion having an inner diameter smaller than that of scroll support portion 51. The bearing portion 53 rotatably supports the main shaft portion 41 of the drive shaft 40. A2 nd annular groove 54 for accommodating an O-ring 56 (see fig. 2) is formed near the upper end of the outer wall of the bearing portion 53.
The coupling portion 55 is a substantially annular portion. Coupling portion 55 couples the lower end portion of scroll support portion 51 and the upper end portion of bearing portion 53 to each other.
The frame 60 supports the floating member 50. The frame 60 is formed substantially in a cylindrical shape. The frame 60 is fixed to the casing 10 in the 2 nd casing space S2 by press fitting, for example. The frame 60 has a fixing portion 61 and a protruding portion 62.
The fixing portion 61 is a substantially cylindrical portion. The outer peripheral surface of the fixing portion 61 is fixed to the casing 10. The fixed scroll 21 is fixed to the upper surface of the fixing portion 61.
The protruding portion 62 is a portion formed substantially in a cylindrical shape or a ring shape. The protruding portion 62 protrudes inward in the radial direction X from the inner peripheral portion of the fixed portion 61. A 3 rd annular groove 63 for accommodating a seal member 65 (see fig. 2) is formed near the inner periphery of the upper surface of the protruding portion 62. The 3 rd annular groove 63 is an example of a seal groove of the present invention. The radially inward X represents a direction approaching the drive shaft 40 in the radial direction X.
A through hole 64 is formed radially inside the protruding portion 62. The drive shaft 40 and the bearing 53 are inserted through the through hole 64.
The 1 st space 71 is formed between the coupling portion 55 of the float member 50 and the protruding portion 62 of the bearing portion 53 and the frame 60. The 1 st space 71 is located on the outer peripheral side of the bearing portion 53 and between the floating member 50 and the frame 60. The 1 st space 71 is partitioned by the O-ring 56 housed in the 2 nd annular groove 54 and the annular seal member 65 housed in the 3 rd annular groove 63. The 1 st space 71 extends over the entire circumference of the casing 10 in the circumferential direction. The high pressure, which is the pressure of the fluid compressed by the compression mechanism 20, is introduced into the 1 st space 71.
A1 st introduction passage 66 is formed inside the fixed scroll 21 and the frame 60. The inflow end of the 1 st introduction passage 66 opens at the discharge port 25. The outflow end of the 1 st introduction passage 66 opens into the 3 rd annular groove 63.
The 2 nd space 72 is formed between the scroll support portion 51 and the coupling portion 55 of the floating member 50 and the protruding portion 62 of the frame 60. The 2 nd space 72 is located between the floating member 50 and the frame 60. The 2 nd space 72 is partitioned by an O-ring (not shown) accommodated in the 1 st annular groove 52 and the seal member 65 accommodated in the 3 rd annular groove 63. The 2 nd space 72 extends in the circumferential direction of the casing 10 over the entire circumference. An intermediate pressure higher than the pressure of the fluid sucked into the compression mechanism 20 and lower than the pressure (high pressure) of the fluid discharged from the compression mechanism 20 is introduced into the 2 nd space 72.
A2 nd introduction passage 67 is formed inside the fixed scroll 21 and the frame 60. The inflow end of the 2 nd introduction passage 67 opens into the compression chamber S20. The outflow end of the 2 nd introduction passage 67 opens into the 2 nd space 72.
The operation of the scroll compressor 1 will be described.
As shown in fig. 1, when electric power is supplied to the motor 30, the rotor 32 of the motor 30 rotates, and the drive shaft 40 is rotationally driven. By rotationally driving the drive shaft 40, the orbiting scroll 26 coupled to the drive shaft 40 performs eccentric rotational motion with respect to the fixed scroll 21. Accordingly, the low-pressure fluid is sucked into the compression chamber S20 through the suction pipe and the 2 nd casing space S2, and is compressed in the compression chamber S20. The compressed fluid is discharged from the discharge pipe 12 through the discharge port 25 and the 1 st casing space S1.
The compressed fluid flows from the discharge port 25 into the 1 st introduction passage 66. The fluid is guided from the 3 rd annular groove 63 to the 1 st space 71 through the 1 st introduction passage 66. A high pressure (high pressure) is generated in the 1 st space 71, and the orbiting scroll 26 is pressed toward the fixed scroll 21 by the high pressure via the floating member 50.
The fluid during compression flows from the compression chamber S20 into the 2 nd introduction passage 67. The fluid is introduced into the 2 nd space 72 through the 2 nd introduction passage 67. A slightly higher pressure (intermediate pressure) is generated in the 2 nd space 72, and the orbiting scroll 26 is pressed toward the fixed scroll 21 by the intermediate pressure via the float member 50.
The scroll compressor 1 is further explained with reference to fig. 1 and 2. Fig. 2 is a partially enlarged view of the scroll compressor 1 shown in fig. 1.
As shown in fig. 1 and 2, the 3 rd annular groove 63 includes a seal groove bottom plate 63 a. The seal groove bottom plate 63a represents a bottom (lower portion) of the 3 rd annular groove 63. An introduction hole 63b is formed in the seal groove bottom plate 63 a. The introduction hole 63b is located between the 1 st space 71 and the 2 nd space 72 at a position in the radial direction X. The introduction hole 63b is located in the 1 st space 71 and the 2 nd space 72 at a position close to the 1 st space 71. In the position in the radial direction X, a position a1 of the center in the radial direction X of the introduction hole 63b is provided at a position shifted toward the 1 st space 71 side with respect to a position a2 of the center in the radial direction X of the 3 rd annular groove 63.
The 1 st introduction passage 66 communicates with the introduction hole 63b from below. The 1 st introduction passage 66 includes a1 st portion 66a and a2 nd portion 66b formed in the frame 60. The 1 st portion 66a extends from the outer peripheral side of the 3 rd annular groove 63 to the lower side of the 3 rd annular groove 63. The 2 nd portion 66b extends upward from the 1 st portion 66a and communicates with the introduction hole 63 b.
The introduction hole 63b has a1 st portion W1 overlapping the seal member 65 and a2 nd portion W2 not overlapping the seal member 65 as viewed in the axial direction Y. In the radial direction X, the 2 nd portion W2 is located closer to the 1 st space 71 than the 1 st portion W1.
An end C1 of the introduction hole 63b near the 2 nd space 72 is located closer to the 1 st space 71 than an end D1 of the 3 rd annular groove 63 near the 2 nd space 72.
The operation of the sealing member 65 will be described with reference to fig. 2 and 3. Fig. 2 is a diagram showing a state of the seal member 65 when high pressure is not introduced into the 3 rd annular groove 63. Fig. 3 is a view showing a state of the seal member 65 when high pressure is introduced into the 3 rd annular groove 63. In fig. 3, the arrows of the one-dot chain line indicate the flow of the high pressure.
As shown in fig. 2 and 3, the high pressure flowing through the 1 st introduction passage 66 is introduced from the introduction hole 63b into the 3 rd annular groove 63. The seal member 65 is pushed up by the high pressure introduced from the introduction hole 63b, and is pressed against the rear surface 51a of the scroll support portion 51 and the outer peripheral surface 63c of the 3 rd annular groove 63 so as to close the communication port 72a between the 3 rd annular groove 63 and the 2 nd space 72. As a result, the high pressure introduced from the introduction hole 63b is suppressed from being supplied to the 2 nd space 72 and is supplied to the 1 st space 71.
Effects of the present embodiment-
As described with reference to fig. 1 to 3, an introduction hole 63b into which a high pressure is introduced is formed in the bottom of the 3 rd annular groove 63. Accordingly, since it is not necessary to secure an installation space for the 1 st introduction passage 66 at a position inside the 3 rd annular groove 63, the outer diameter of the 3 rd annular groove 63 can be reduced, and the outer diameter of the seal member 65 can be suppressed from increasing. As a result, excessive pressing of the floating member 50 by the high pressure can be suppressed, and thus, the performance of the scroll compressor 1 can be suppressed from being degraded. Further, by suppressing the outer diameter of the seal member 65 from increasing, the scroll compressor 1 can be downsized.
Further, the introduction hole 63b has a1 st portion W1 overlapping the seal member 65 as viewed in the axial direction Y. Thus, the high pressure introduced from the introduction hole 63b into the 3 rd annular groove 63 is brought into contact with the seal member 65, and the seal member 65 can be effectively floated up to a position where the communication port 72a of the 3 rd annular groove 63 and the 2 nd space 72 is closed (see fig. 3).
Further, the 2 nd portion W2 of the introduction hole 63b is located closer to the 1 st space 71 than the 1 st portion W. Thus, when high pressure is introduced into the 3 rd annular groove 63, the sealing member 65 is floated by the high pressure from the 1 st part W1, and the high pressure from the 2 nd part W2 can be supplied to the 1 st space 71.
Further, the introduction hole 63b is located in the 1 st space 71 and the 2 nd space 72 at a position close to the 1 st space 71. This enables the high pressure introduced from the introduction hole 63b into the 3 rd annular groove 63 to be efficiently supplied to the 1 st space 71.
Further, an end C1 of the introduction hole 63b near the 2 nd space 72 is located closer to the 1 st space 71 than an end D1 of the 3 rd annular groove 63 near the 2 nd space 72. This makes it possible to supply the high pressure introduced from the introduction hole 63b into the 3 rd annular groove 63 to a position close to the 1 st space 71, and therefore, the supply of the high pressure to the 2 nd space 72 can be effectively suppressed.
Although the embodiments and the modifications have been described above, it is understood that various changes in the form and details (for example, the following (1)) can be made without departing from the spirit and scope of the claims. The above embodiments and modifications may be combined or substituted as appropriate as long as the functions of the object of the present invention are not impaired.
(1) As shown in fig. 2, in the present embodiment, a part (the 1 st portion W1) of the introduction hole 63b overlaps the seal member 65 as viewed in the axial direction Y. However, the present invention is not limited thereto. The entire introduction hole 63b may overlap the sealing member 65. This can effectively improve the floating property of the seal member 65 by the high pressure from the introduction hole 63 b.
