[Industrial applications]

 The present invention relates to a set structure of an air-cooled scroll air compressor.

[0002]

[Prior art]

 FIG. 5 was filed by the applicant as Japanese Patent Application No. 62-147221. The air-cooled scroll air compressor main body 10 (hereinafter, simply referred to as the main body) is located below, and the main body 10 is located above the pulley 20. A motor 40 driven via the belt 30 is provided. Here, in the main body 10, the compression heat generated inside during the compression operation is conducted from the fixed scroll 10a and the orbiting scroll 10b to the cooling fins 10c and 10d formed on the respective backs. Cooling air from a cooling fan 10b mounted in the axial direction of the main body 10 passes through the duct 15b to the cooling fins 10c and 10d, and is forcibly supplied to the cooling fins 10c and 10d to take away heat. After that, exhaust hot air is discharged to the atmosphere from an exhaust port provided on one side surface on the front side of the main body 10 in a direction perpendicular to the drive shaft of the main body. As a result, the temperature rise of the bearings and seals of the main body is suppressed and the service life is extended, and the compression efficiency is improved with the cooling effect.

[0003]

[Problems to be solved by the device]

 The main body 10 is housed in a package and put on the market as a package compressor. In this case, the exhaust hot air after cooling the main body 10 is configured to be discharged to the outside of the package. However, since the main body 10 does not generate high-frequency sound and does not generate unpleasant sound, a set configuration in which the main body is mounted on a portable air tank without being housed in a package is also desired. . In addition, two main units are mounted on the air tank, and when using a large amount according to the amount of air used, both main units perform compression operation. There is also a demand for a compressor that saves energy by performing compression control on only one main unit and stopping the two main units when not in use. Therefore, as shown in FIG. 6, when the drive shaft 10a of the main body 10 is arranged in parallel at a right angle to the longitudinal direction 50a of the two air tanks 50, when the main body 10 is compressed, the main body 10 is compressed. Since one side surface on the front side of the main body has an exhaust port 10g provided in the direction perpendicular to the drive shaft 10a after cooling the main body, the exhaust port 10g of one main body faces the other main body 10. The exhaust hot air exhausted from the exhaust port 10g of the one main body 10 directly hits the other main body. As a result, the temperature of the other main body 10, which is hit by the exhaust hot air, rises, cooling is impaired, and the life of the bearings and seals of the main body 10 is reduced. In order to eliminate this, as shown in FIG. 7, it is possible to shift one main body 10 relative to the other main body 10 only in the front-back direction so that the exhaust hot air from the exhaust port 10g does not hit. In that case, the width in front of and behind the base 55 on the air tank 45 must be increased. Therefore, it was difficult to use the set when it was heavy and the installation space was small.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an explanatory plan view of an air tank. Reference numeral 1 is an air tank, 1a is a longitudinal direction of the air tank 1, and wheels 1b are attached below the air tank 1 so as to be movable. Two bases 2 are fixed to the upper surface of the air tank 1 at intervals. Each of the bases 2 is provided with a mounting hole 2a for mounting the main bodies 3 and 3 with bolts and nuts. Incidentally, the stud bolt 2a may be erected here instead of the bolt and nut. FIG. 2 is a plan view showing a state where the main body and the motor are attached to the air tank. The four mounting holes 2a on one side of the base 2 (on the left side when viewed from the front side) are arranged such that the axial direction of the drive shaft 3b of the main body 3 is the longitudinal direction 1a of the air tank 1 when viewed from the front. , It is attached at a right angle. Further, the four mounting holes 2a or the stat bolts 2a on the other side of the base 2 (on the right side when viewed from the front side) are arranged so that the axial direction of the drive shaft 3b of the other main body 3 is viewed from the front side. It is attached at a position of at least 45 ° in the clockwise direction with respect to the longitudinal direction 1a. A motor 4 for driving the main bodies 3 and 3 via a pulley 7 and a belt 8 is mounted on top of each of the main bodies 3 and 3. Further, two electromagnetic switches 5 are mounted in parallel in the front and rear on the upper end (right end) of the air tank 1. The inlet of the electromagnetic switch 5 is a commercial power source, and the outlet is a power source for the respective motors 4, 4. Connected via cords 6, 6. Now, when the power is turned on, a current flows through the two motors 4 and 4 at the same time or after a slight delay, the motors 4 and 4 rotate, and the motor pulleys 7 and 7 and belts 8 and 8 are used to drive the 3 The pulleys 30a, 30a of 3 are rotated in a predetermined rotation direction, and the drive shafts 3b, 3b attached to the pulleys 30a, 30a of the main bodies 3, 3 at right angles are rotated. When the drive shafts 3b and 3b rotate, the orbiting scrolls 3d and 3d perform an orbiting motion with respect to the fixed scrolls 3c and 3c, and the atmospheric air sucked from the suction port on the outer peripheral side contracts in volume toward the center. While proceeding, the air tank 1 is compressed and is filled into the air tank 1 through the connecting pipe from the central discharge port. Now, when the amount of air used is less than the medium amount, shut off one electromagnetic switch and operate only the other main unit. When a small amount or when not in use, shut off both electromagnetic switches and stop both main units. If a large amount of air is used, activate both electromagnetic switches to operate both main units. Now, in the compression operation state, compression heat is generated, but as shown in FIG. 5, cooling air is generated by the cooling fans 3b, 3b mounted in the axial direction of the main bodies 3, 3, and the duct 3b, Cooling air is generated by the fixed scroll 3c of the compressor section of the compressor and the cooling fans 3b and 3b provided on the rear surface of the orbiting scroll 3d via the duct 3b and 3b, and the fixed scroll of the compressor section of the compressor via the ducts 3b and 3b. 3c and the swirl scroll 3d are supplied to the cooling fin portion having the back surface for forced cooling, so that the compression heat is taken and discharged from the exhaust port 3g, so that a good compression operation can be maintained.

Here, the exhaust hot air discharged from the exhaust port 3g of the left main body 3 is in a direction perpendicular to the drive shaft 3b of the main body, that is, in the direction parallel to the longitudinal direction 1a of the air tank 1, and in the figure, the left side is shown. Since it is discharged only in the direction, the exhaust hot air does not hit the other main bodies 3 and there is no fear of the temperature rise of the other main bodies 3. Further, the exhaust hot air discharged from the exhaust port 3g of the right side main body 3 has a drive shaft 3b direction of the main body 3 with respect to the longitudinal direction 1a of the air tank 1 at least 45 in the clockwise direction when viewed from the front of the set. It is designed to stick to the ° position. That is, since the exhaust port 3g of the right main body 3 is configured not to face the left main body 3, the exhaust hot air exhausted from the exhaust port 3g of the main body 3 flows as indicated by the arrow, and thus the left main body 3 It does not hit 3 directly. Therefore, the main body 3 on the left side can be operated satisfactorily without causing a problem of temperature rise due to the exhaust hot air of the main body 3 on the right side. FIG. 3 is a plan view of another embodiment in which the main body and the motor are attached to the air tank. The mounting holes 2a or the stud bolts 2a of the base 2 on either the right side or the left side when viewed from the front are at least clockwise with respect to the longitudinal direction 1a of the air tank 1 when the drive shaft 3b direction of the main body 3 is viewed from the set front. It is attached to the 45 ° position. Therefore, since the main bodies 3 and 3 are mounted on the bases 2 and 2, respectively, the mutual exhaust ports 3g are configured so as not to face the counterpart main body 3. Here, even when the two main bodies enter the compression operation, the exhaust hot air exhausted from the exhaust port 3g of the right main body 3 flows as shown by the arrow, and therefore does not directly hit the left main body 3. Therefore, the left side main body 3 can be operated satisfactorily without causing a problem of temperature rise due to the exhaust hot air of the right side main body 3. FIG. 4 is a plan view of another embodiment in which the main body and the motor are attached to the air tank. Two bases 2 and 2 are mounted on the air tank 1. Mounted on the right side base 2 so that the direction of the drive shaft 3b of one body 3 is attached to the longitudinal direction 1a of the air tank 1 at a position of at least 45 ° in the clockwise direction when viewed from the front of the set. A hole 2a or a stat bolt 2a is provided. The drive shaft 3b of the other main body 3 is attached to the left base 2 at a position of at least 45 ° in the counterclockwise direction when viewed from the front of the set with respect to the longitudinal direction 1a of the air tank 1. A mounting hole 2a or a stat bolt 2a is provided. Motors 4 and 4 for driving the main bodies 3 and 3 via a pulley 7 and a belt 8 are mounted on the upper portion of the main body 3. Therefore, even if the left and right main bodies 3 and 3 enter the compression operation, the exhaust port 3g of one main body 3 is configured not to face the other main body 3, and the exhaust air from the exhaust port 3g of one main body 3 is exhausted. The exhausted hot air does not hit the other body 3 and does not raise the temperature of the other body 3 to an abnormal state. Therefore, the cooling fins at the back of the fixed scroll and the orbiting scroll are forcibly cooled by the cooling air from the cooling fans attached to the two main bodies 3 and 3 on the left and right sides, so that the compression heat is not generated. Since it is taken and released from the exhaust port, good compression operation is maintained even if two air-cooled scroll compressors are installed above the air tank, and the main body is driven upward via pulleys and belts. can do.

[0008]

[Effect of device]

 An air-cooled scroll air compressor body having a cooling fan in the body, wherein the air-cooled scroll air compressor body is placed below, and a motor for driving the body via pulleys and belts is placed above the body. Even when two air-cooled scroll air compressors are installed on the air tank, the exhaust hot air discharged from the exhaust port of one main unit does not directly hit the other main unit, so the temperature of the other main unit becomes abnormal. It is possible to perform good compression operation with the two main units on the air tank without increasing the pressure. Further, since the electromagnetic switch is arranged at the inlet of each motor, the operation of the two main bodies can be controlled according to the amount of air used, and energy saving can be achieved.
