Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an open-type compressor device that uses external power to change the volume of a compression chamber formed in a casing, sucks refrigerant from an inlet, and discharges high-pressure refrigerant compressed from an outlet. In particular, the present invention relates to the control of an open type compressor apparatus provided with an electromagnetic clutch mechanism for connecting / disconnecting external power.
[0002]
[Prior art]
Conventionally, an open type compressor apparatus is driven by external power (for example, an engine or the like). For example, this type of apparatus is disclosed in Japanese Patent Laid-Open No. 11-303777. The above publication discloses a scroll compressor which is one of open-type compressor devices. In the apparatus shown here, a fixed scroll and a movable scroll are disposed in a casing, and a compression chamber for compressing a working fluid (for example, a refrigerant) is formed between the scrolls. Then, the driving force of the engine is transmitted to the pulley via the compressor belt, and the driving force transmitted to the pulley is transmitted to the shaft via the electromagnetic clutch, so that the movable scroll pivotally incorporated in the shaft is swung. .
[0003]
The movable scroll is swiveled with respect to the fixed scroll, and the refrigerant (including lubricating oil) sucked from the suction port formed in the casing moves to the fixed scroll by the swiveling movement of the movable scroll. A configuration in which a high-pressure refrigerant is discharged from a discharge port through a compression chamber formed between a spiral body provided in the movable scroll and a spiral body provided in the movable scroll, which gradually decreases in volume, led to the center of the fixed scroll. It has become.
[0004]
In the above configuration, the refrigerant flows around the shaft. However, a shaft seal member (mechanical seal) is provided on the shaft so that the refrigerant present in the front housing does not flow into the atmosphere. Is provided.
[0005]
As the seal member used in the compressor described above, for example, a seal member made of rubber or the like is used, so that the refrigerant present in the front housing does not flow out into the atmosphere. In such a configuration, the shaft has a shaft sealing member on the shaft. However, the compressor is not operated at a low temperature, or the compressor is kept cold for a long time (for example, the compressor is left unattended). When rubber or the like is used for the seal member, the seal member is cured due to its material characteristics. As a result, a leakage of refrigerant or the like may occur at the time of startup after being left for a predetermined time.
[0006]
Japanese Patent Laid-Open No. 2002-31386 discloses a method of using a heater for preheating the compressor in order to prevent damage caused by starting up the compressor at a low temperature and improve the startup of the compressor. .
[0007]
[Problems to be solved by the invention]
As described in the above publication, in the method of preheating the compressor with the heater, the heater is used for preheating the compressor, so that the mechanical seal can be prevented from being hardened and the sealing performance around the shaft can be ensured. However, a heater for ensuring the sealing performance is required, resulting in an increase in cost.
[0008]
Accordingly, the present invention has been made in view of the above-described problems, and an object of the present invention is to ensure sealing performance at the time of starting the compressor by an inexpensive method.
[0009]
[Means for Solving the Problems]
The first technical means taken in order to solve the above-described problem is that a casing having an internal space and having a suction port and a discharge port, a fixing member disposed in the casing, and a fixing member A movable member that performs a revolving movement with respect to the shaft, a shaft that rotatably supports the movable member with respect to a front housing fixed to the casing, and a seal member that is disposed between the shaft and the front housing. And a driven member that is arranged coaxially with the shaft and is driven to rotate by external power, and is arranged between the driven member and the shaft and rotates the driven member by energizing the coil. An electromagnetic clutch mechanism that connects and disconnects the shaft, and a control means that controls the electromagnetic clutch mechanism, and is formed between the fixed member and the movable member in the internal space. In the open-type compressor apparatus in which the working fluid is sucked into the compression chamber from the suction port and compressed by the swiveling motion of the movable member and discharged from the discharge port, the control means has its external power stopped operating. In this case, the coil is energized for a predetermined time.
[0010]
According to the above means, when the external power stops operating, the control means energizes the coil for a predetermined time if the external power is energized for a predetermined time even after the external power is stopped (for example, by a timer or a relay). ) Can generate heat in the coil. Due to the heat generated by the coil, the seal member is warmed through the housing. This makes it possible to prevent the sealing member from being hardened by the heat accompanying the heat generation of the coil when the external power is started after being left for a predetermined time, and to ensure the sealing performance around the shaft.
[0011]
The second technical means taken in order to solve the above-mentioned problem is that a casing having an internal space and having a suction port and a discharge port, a fixing member disposed in the casing, and the fixing A movable member that performs a pivoting motion with respect to the member, a shaft that pivotally supports the movable member with respect to a front housing fixed to the casing, and a shaft disposed between the shaft and the front housing. A seal member, a driven member disposed coaxially with the shaft, and driven to rotate by external power; disposed between the driven member and the shaft; and energizing the coil to drive the driven member An electromagnetic clutch mechanism for connecting / disconnecting rotation of the clutch to / from the shaft, and a control means for controlling the clutch mechanism, and formed between the fixed member and the movable member in the internal space. Relative compression chamber, and compressed by orbiting movement of the movable member to suck the working fluid from the inlet, the open-type compressor unit to be discharged from the discharge port,
[0012]
  Temperature detecting means for detecting the temperature of the external power,AboveThe control meansAboveWhen the temperature is lower than the first predetermined temperature, the coil is energized.
[0013]
  According to the above-described means, the temperature of the external power is detected by the temperature detection means, and the control means for controlling the clutch mechanismOutsideIf the coil is energized when the power temperature is lower than the first predetermined temperature, the coil generates heat by energizing the coil. The heat generated by the coil warms the seal member through the front housing. by this,Start-upIn this case, it becomes possible to prevent the sealing member from being hardened by the heat accompanying the heat generation of the coil, and it is possible to ensure the sealing performance around the shaft.
[0014]
In this case, the coil is supported by the front housing, and if the driven member is formed with a recess in the axial direction, and the coil is disposed in the recess, the coil is supported by the front housing, and the shaft of the driven member is Since it is accommodated in the recess formed in the direction, it does not increase in the axial direction.
[0015]
The clutch plate is supported by the shaft and is opposed to the driven member. When the coil is energized, the clutch plate is integrated with the driven member, and the shaft and the driven member are integrated. If it rotates, it becomes possible to ensure the sealing performance around the shaft by using the configuration of an electromagnetic clutch mechanism that transmits external power to the shaft. Therefore, components (for example, heaters) used only for preheating the compressor are No longer needed.
[0016]
  Further, the control means has a temperature higher than the second predetermined temperature set higher than the first predetermined temperature.NoIf the coil is energizedBecause I do not doOnly when it is necessary to ensure sealing performance (for example, at a low temperature), the coil can be energized, and the power consumption can be suppressed.
[0017]
In addition, if the open type compressor device is used as a refrigerant compressor, when the open type compressor device is started at a low temperature, the seal member from the stop state of the external power in the air conditioner (for example, a gas heat pump) is used. A reliable seal can be achieved. For example, normally, in a compressor used in an engine-driven air conditioner, a heater is used to preheat the compressor. In the air conditioner having the above-described configuration, the electromagnetic clutch mechanism of the open compressor apparatus is used. By energizing the coil, it becomes possible to preheat the compressor, so that a heater used for preheating the compressor is not necessary. In addition, since it is possible to prevent the refrigerant from collecting in the compressor at a low temperature, the seal member is deteriorated (for example, foaming is prevented when an O-ring is used). Initial lubrication failure is avoided.
[0018]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0019]
FIG. 1 is a cross-sectional view of a scroll compressor (simply referred to as a compressor) 10 having an electromagnetic clutch mechanism 20 in the open type compressor apparatus 1 of the present invention. The compressor 10 includes a metal casing 3 having a suction port 3a for sucking a working fluid (for example, refrigerant or lubricating oil) from the outside, and a discharge port 3b for discharging the refrigerant compressed inside to a high pressure to the outside. In an internal space 9 formed by a metal front housing 2 that is integral with the casing 3 and rotatably supports the shaft 4, a rotating body including a shaft 4, an eccentric bush 5, a movable scroll 7, and the like, which will be described later, is housed. The front housing 2 and the casing 3 are fixed by fastening members such as bolts.
[0020]
The front housing 2 is provided with a compressor pulley (simply referred to as a pulley) 8 coaxially with the shaft 4 and an engine pulley (simply referred to as a pulley) 41 that transmits rotation from the engine 40 to the outside. As shown in FIG. 2, a belt 42 is hung between them, and the rotational force (driving force) of the engine 40 is transmitted to the shaft 4 of the compressor 10 via the belt 42, the pulley 8, and the electromagnetic clutch 20. It has a configuration.
[0021]
The shaft 4 has a large diameter portion 4a at the center. In the front housing 2, the shaft 4 is supported by a bearing 22 on the pulley side, and is supported by a bearing 23 at a large diameter portion 4 a in the center of the shaft 4. The outer rings of the bearings 22 and 23 are press-fitted together with the inner wall of the recess formed in the front housing 2. Further, the shaft 4 is fitted to the inner rings of the bearings 22 and 23, and the shaft 4 is rotatably supported with respect to the front housing 2.
[0022]
Between the bearings 22 and 23, two annular seal members 11 (11a and 11b) are disposed as mechanical seals in order to achieve sealing performance around the shaft. The seal member 11 seals communication between the space 9 a formed on the side of the bearing 22 and the space 9 b formed on the pulley side of the bearing 23, and the seal member 11 a is in the space formed in the front housing 2. It is fitted at the small diameter part. The seal member 11b is fitted on the shaft coaxially with the shaft. With such a configuration, the seal member 11a is fixed and does not rotate with respect to the front housing 2, but the seal member 11b is rotated by the rotation of the shaft 4, but the spaces 9a and 9b are separated by the seal members 11a and 11b. Sealability is ensured.
[0023]
Further, an eccentric bush 5 having an eccentric center is provided on the shaft 4 on the opposite side of the large diameter portion 4a from the side where the pulley 8 is provided. When the eccentric bush 5 is rotated by the rotation of the shaft 4, the counter weight is set so as to be balanced against the rotation of the eccentric bush 5 and the orbiting motion of the movable scroll, and to prevent vibration during rotation. It is attached to the eccentric bush 5.
[0024]
On the other hand, the casing 3 has a bottomed cylindrical shape, and an internal space 9 is formed in a state where the casing 3 is assembled with the front housing 2. In the internal space 9 of the casing 3, a fixed scroll 6 and a movable scroll 7 that performs a turning motion with respect to the fixed scroll 6 are disposed. The fixed scroll 6 is fixed to the inner wall of the casing 3 by a fastening member 13 such as a bolt and does not rotate. On the left side (pulley side) shown in FIG. 1, the fixed scroll 6 is integrally formed with a spiral portion 6 a that spirals from the center of the fixed scroll 6. In addition, a movable scroll 7 is disposed so as to face the fixed scroll 6. When the shaft 4 is driven to rotate, the movable scroll 7 is driven by the eccentric bush 5 and the ball coupling which is a movable scroll rotation preventing mechanism. A swivel motion is performed with respect to the axis 4. In this case, the movable scroll 7 is formed integrally with the movable scroll 7 with a spiral portion 7 a having the same shape as the spiral portion 6 a that enters the spiral portion 6 a formed in the fixed scroll 6. As a result, the movable scroll 7 orbits with respect to the fixed scroll 6, but a compression chamber 14 is formed between the scrolls 6 a and 7 a of the scrolls 6 and 7. In the compression chamber 14, the volume of the compression chamber 14 gradually decreases from the outside toward the center, the refrigerant inside the compression chamber 14 is compressed, the pressure at the center becomes the highest, and the refrigerant that has become the high pressure due to the compression is discharged from the discharge port. It becomes the structure discharged from 3b.
[0025]
Next, the configuration on the pulley side of the shaft 4 will be described. A boss portion 2a through which the shaft 4 passes is formed at one end of the front housing 2 in the axial direction. A cylindrical pulley 8 made of metal and coaxial with the shaft 4 is disposed on the outer diameter of the boss portion 2a. The inner diameter of the pulley 8 is larger than the diameter of the boss portion 2 a, and the pulley 8 is rotatable with respect to the front housing 2 via the bearing 24. The pulley 8 has a V-groove formed on the outer diameter, and the belt 42 is hung on the V-groove. Further, the pulley 8 is formed with an annular recess 8a on the right side in the axial direction shown in FIG. 1, and the coil 21 is disposed in the recess 8a. The coil 21 is attached to the side surface 2 b in the axial direction of the front housing 2 via an annular plate member 25. An annular coil ring 26 having an opening in the axial direction is fixed to the plate member 25 by spot welding, and a coil 21 wound in the circumferential direction is disposed inside the coil ring 26. In this case, the pulley 8 is rotatable with respect to the coil ring 26 in a state where the recess 8 a formed in the pulley 8 and the coil ring 26 having an opening are kept at a predetermined interval.
[0026]
The pulley 8 is made of a metal material, and the end surface 8b in the axial direction is perpendicular to the shaft 4, and the annular clutch plate 15 is disposed facing the pulley 8 from the axial direction. The clutch plate 15 includes an armature, a boss, a plate, and a leaf spring 27, and the shaft and the boss are fixed by a nut 28 at the end of the shaft 4. One end of the boss, the plate, and the leaf spring 27 is fixed by a rivet 29a, and the other end of the armature and the leaf spring 27 is fixed by a rivet 29b. That is, the plate and the armature are connected by the leaf spring 27.
[0027]
Between the shaft 4 and the pulley 8, there is provided an electromagnetic clutch mechanism 20 for connecting / disconnecting power transmission to / from the compressor 10 from the external power. The electromagnetic clutch mechanism 20 includes the coil 21, the pulley 8 and the clutch. A plate 15 is provided. By supplying power to the coil 21 from outside via a connector (not shown) and energizing the coil 21, a current flows through the coil 21, and the axial end surface of the pulley 8 and the armature disposed so as to be opposed thereto are attracted by electromagnetic force. The As a result, the armature comes into contact with the end face 8 b of the pulley 8 to rotate integrally, and the rotational force of the pulley 8 is transmitted to the shaft 4. On the other hand, when energization of the coil 21 is stopped, the armature is separated from the side surface of the pulley 8 by the urging force of the leaf spring 27, and the rotational force that rotates the pulley 8 is cut off and is not transmitted to the shaft 4.
[0028]
The structure of the open type compressor apparatus 1 in this embodiment is shown in FIG. In FIG. 2, the power from the engine 40 is transmitted to the compressor 10 by the belt 42, and the electromagnetic clutch mechanism 20 provided in the compressor 10 is controlled by the control device 30. The control device 30 includes a temperature sensor 41 for detecting the temperature of the engine 40 and a remote controller 43 for driving or stopping the compressor 10 by a switch operation, and outputs a drive signal to the electromagnetic clutch mechanism 20 based on these signals. Then, the electromagnetic clutch mechanism 20 is operated. When the electromagnetic clutch mechanism 20 is operated, the refrigerant is sucked from the suction port 3a, and the refrigerant sucked inside the compressor is compressed to a high pressure and discharged from the discharge port 3b. In this case, when the output signal of the temperature sensor 41 input to the control device 30 becomes lower than a predetermined temperature (first predetermined temperature) T1, the output signal is turned on (ON state), and a predetermined temperature (second predetermined temperature) higher than the predetermined temperature T1. When the temperature becomes higher than T2, an OFF state (OFF state) is output, and a drive signal is output to the electromagnetic clutch mechanism 20 based on a drive command from the remote controller 43.
[0029]
Thus, the open type compressor apparatus 1 in which the electromagnetic clutch mechanism 20 is controlled can be used for an air conditioner as a refrigerant compressor.
[0030]
Next, the operation will be described. The driving force of the engine 40 is transmitted to the pulley 8 via the belt 42 stretched around the pulleys 41 and 8 to rotate the pulley 8. In this case, when a drive signal is not output from the control device 30 to the electromagnetic clutch mechanism 20 (for example, in a low potential state), the coil 21 is not energized, the clutch is disconnected, and the shaft 4 is powered. Is not transmitted. On the other hand, when a drive signal is output from the control device 30 to the electromagnetic clutch mechanism 20 (for example, in a high potential state), the coil 21 is energized and an electromagnetic attractive force acts on the armature. Thus, the pulley 8 and the armature are united by being sucked to the pulley side. As a result, the pulley 8 and the clutch plate 15 rotate integrally, and the driving force from the engine 40 is transmitted to the shaft 4.
[0031]
As described above, when the driving force from the engine 40 is transmitted to the shaft 4, the movable scroll 7 is swung with respect to the fixed scroll 6 by the rotation of the shaft 4. In this case, the refrigerant sucked from the suction port 3a by the turning motion of the movable scroll 7 is taken in from the outer diameter side of the scrolls 6 and 7, and the scroll is formed by the compression chamber 14 formed by both scrolls and gradually reducing the volume. Guided to the center of the. Then, the refrigerant guided to the central portion passes through a hole provided in the central portion of the fixed scroll 6 and out of the scroll formed inside the housing 3, passes through a passage (not shown), and is discharged from the discharge port 3b. In addition, the refrigerant around the shaft tends to flow from the circumference of the shaft 4 to the pulley side, but since the seal members 11a and 11b are provided in the middle, leakage of the refrigerant to the atmosphere side is prevented.
[0032]
  In this case, when the compressor 10 is cooled to a certain value or less, when an elastic member such as rubber is used for the seal members 11a and 11b, it is hardened at a low temperature and it is difficult to secure the sealability around the shaft 4. Become. Therefore, in this embodiment, the temperature of the engine 40 andShutdownThe coil 21 is energized as necessary, and the heat generated by the coil energization is used to prevent the seal member 11 from hardening and to ensure a reliable sealing performance.
[0033]
Therefore, processing in the control device 30 will be described with reference to FIG. In the following description, the steps in the program are simply described as “S”.
[0034]
  When power is supplied to the control device 30, the program is executed. In S1, the control device 30Predetermined after shutdownIt is determined whether time has passed. Therefore, if the predetermined time (for example, 30 minutes) has not elapsed, nothing is done to the electromagnetic clutch mechanism 20, but if the predetermined time has elapsed, the process proceeds to S2, and in S2, based on the output of the temperature sensor 41. Whether the temperature is lower than a first predetermined temperature (for example, 0 degrees) is determined. Therefore, when the engine temperature is lower than the first predetermined temperature, a drive signal is output to the electromagnetic clutch mechanism 20, and it is determined that the compressor 10 is cold, and the coil 21 is energized.To do.When the coil 21 is energized, the coil 21 generates heat, and the heat is transmitted through the coil ring 26 and the plate member 25 to escape to the front housing 2, thereby warming the front housing 2. Thereafter, the seal member 11a fixed to the front housing 2 is warmed. And heat is transmitted also to the sealing member 11b which contacts the sealing member 11a. Further, the shaft 4 itself also indirectly receives heat from the front housing 2, and the temperature of the seal member 11b is easily prevented from decreasing. When the seal member 11a is warmed by the heat generated by the coil 21, curing is prevented when rubber or the like is used, and sufficient sealing performance can be provided around the shaft 4.
[0035]
On the other hand, if the engine temperature is higher than the first predetermined temperature in S2, it is determined in S4 whether it is higher than a second predetermined temperature (for example, 5 degrees) higher than the first predetermined temperature. Here, if the engine temperature is lower than the second predetermined temperature (between the first predetermined temperature and the second predetermined temperature), the process proceeds to S6. However, if the engine temperature is higher than the second predetermined temperature, the electromagnetic clutch mechanism 20 in S5. In contrast, the drive signal (high potential) is not output, the transmission of power from the engine 40 is cut off, and is not transmitted to the shaft 4. Thereafter, in S6, it is determined whether or not a signal from the operation switch from the remote controller 43 is input. If the signal is not input, the processing from S1 is repeated, but if the operation switch from the remote control 43 is in the ON state. Transition to normal system operation.
[0036]
  Further, as another method for securing the sealing performance around the shaft, the method shown in FIG. 5 may be used. In FIG. 5, when power is supplied to the control device 30, a program is executed. In S11, the control device 30Predetermined timeEngine 40 has stopped operatingOrIs judged. Therefore, if the predetermined time has not elapsed, nothing is done to the electromagnetic clutch mechanism 20, but if the predetermined time has elapsed, the process proceeds to S12. In S12, a drive signal is sent to the electromagnetic clutch mechanism 20 for a predetermined time ( For example, the seal member 11a, 11b is heated and the coil 21 is energized by outputting only the time until the seal member 11a, 11b is in a state where sufficient sealability can be ensured. Energization of the coil 21If done,The coil 21 generates heat, and the heat is transmitted to the coil ring 26 and the plate member 25 so that the heat escapes to the front housing 2 and the front housing 2 is warmed. Thereafter, the seal member 11a fixed to the front housing 2 is warmed. As a result, when both the sealing members 11a and 11b are warmed by the heat generated by the coil 21, curing is prevented when rubber or the like is used, and sufficient sealing performance can be provided around the shaft 4. it can.
[0037]
  Thereafter, in S13, it is determined whether or not a signal from the operation switch from the remote controller 43 has been input. If the signal is not input, the processing from S11 is repeated, but if the operation switch from the remote control 43 is on. After the energization of the coil 21 of the electromagnetic clutch mechanism 20 is stopped, the system shifts to normal system operation.To do.
[0038]
【effect】
According to the present invention, when the external power stops operating, the control means can heat the coil by energizing the coil even after the external power is stopped if the coil is energized for a predetermined time. Due to this heat generation, the sealing member can be warmed through the housing. For this reason, when starting after leaving external power for a predetermined time, hardening of a sealing member can be prevented with the heat | fever accompanying the heat_generation | fever of a coil, and the sealing performance around a shaft can be ensured.
[0039]
Further, according to the present invention, when a predetermined time elapses after a drive instruction is given to the electromagnetic clutch mechanism to the control means for controlling the electromagnetic clutch mechanism, and the temperature of the external power is lower than the first predetermined temperature, the coil If energization is performed, the coil generates heat by energizing the coil, and the seal member can be warmed through the housing by the heat generation of the coil. Accordingly, the sealing member can be prevented from being hardened by the heat accompanying the heat generation of the coil, and the sealing performance around the shaft can be ensured. This eliminates the need for a heater used only to preheat the compressor.
[0040]
In this case, the coil is supported by the housing, and the driven member is formed with a recess in the axial direction. If the coil is disposed in the recess, the coil is supported by the housing in the axial direction of the driven member. Since it is stored in the formed recess, it can be miniaturized in the axial direction.
[0041]
The clutch plate is supported by the shaft and is opposed to the driven member. When the coil is energized, the clutch plate is integrated with the driven member, and the shaft and the driven member are integrated. If it rotates, the sealing performance around the shaft can be secured by using the configuration of an electromagnetic clutch mechanism that transmits external power to the shaft.
[0042]
Further, when the temperature becomes higher than the second predetermined temperature when the temperature becomes higher than the second predetermined temperature set higher than the first predetermined temperature, when the energization to the coil is stopped, the temperature becomes higher than the second predetermined temperature. As the seal member is not cured by energization of the coil and sufficient sealing performance can be secured, the coil can be energized only when necessary to ensure sealing performance (for example, at low temperatures). Power consumption can be reduced.
[0043]
Furthermore, if the open type compressor device is used as a compressor for refrigerant, when the open type compressor device is started at a low temperature, the air conditioner can securely seal with a seal member from a stopped state of external power. Can do. In the air conditioner having the above-described configuration, the compressor can be preheated by energizing the coil of the electromagnetic clutch mechanism of the open compressor device, and the heater used for preheating the compressor is not necessary. Preheating can be performed at low cost. Furthermore, it is possible to avoid deterioration of the seal member and poor initial lubrication at the time of startup.
