Simplified air compressors may have smaller discharge outputs than stationary large-sized air compressors. However, because simplified air compressors are light and small and can be easily carried about, they can be conveniently used when performing simple and light duty work involving pneumatic tools.
U.S. Patent No. 7,140845 andJP-A-2-108878 - The simplified air compressors disclosed in the above documents typically have an electric motor and a compressing device that are disposed within a resin case. The compressing device may convert the rotational output of the electric motor into a reciprocating movement of a piston within a cylinder for discharging compressed air. The compressed air discharged from the compressing device may be directly supplied to a pneumatic tool.

-
JP-A-2006-220102 - The air compressors disclosed in the above documents still require improvements. For example, if an external auxiliary tank is connected to the battery driven air compressor for supplying a larger output of compressed air, a larger electric power is necessary to be supplied by the battery. In this case, it may be possible to cause lack of residual power in the battery. For this reason, it is necessary to frequently recharge or replace the battery. As a result, it is necessary to frequently stop the work, leading to low productivity.
- Therefore, there has been a need in the art for a technique for fixing the lack of power in an air compressor that results when an external tank is used.
- The invention is defined in claim 1.
- Additional objects, features, and advantages, of the present invention will be readily understood after reading the following detailed description together with the claims and the accompanying drawings, in which:
-
FIG 1 is a diagram showing the configuration of an air compressor according to a first embodiment, in which a pneumatic tool is connected to an external tank unit; -
FIG. 2 is a diagram showing the configuration of an air compressor according to a second embodiment, in which a pneumatic tool is connected to a compression unit; and -
FIG. 3 is a diagram showing the configuration of an air compressor according to a third embodiment, in which a compression unit is schematically shown. - Each of the additional features and teachings disclosed above and below may be utilized separately or in conjunction with other features and teachings to provide improved air compressors. Representative examples of the present invention, which examples utilize many of these additional features and teachings both separately and in conjunction with one another, will now be described in detail with reference to the attached drawings. This detailed description is merely intended to teach a person of skill in the art further details for practicing preferred aspects of the present teachings and is not intended to limit the scope of the invention. Only the claims define the scope of the claimed invention. Therefore, combinations of features and steps disclosed in the following detailed description may not be necessary to practice the invention in the broadest sense, and are instead taught merely to particularly describe representative examples of the invention. Moreover, various features of the representative examples and the dependent claims may be combined in ways that are not specifically enumerated in order to provide additional useful examples of the present teachings. Various examples will now be described with reference to the drawings.
- In one example, an air compressor may include a compressor unit and an external tank unit. The compressor unit may supply a compressed air to a pneumatic tool. The external tank unit may be connectible with the compressor unit. The external tank unit may include an external tank and a battery. The external tank may store the compressed air. The battery may supply an electric power to the compressor unit.
- Therefore, when the external tank is connected to the compressor unit for enabling the compressor unit to supply a larger output of compressed air to the pneumatic tool, it is possible to supply electric power to the compressor unit from the battery of the external tank unit. In this way, it is possible to supply a larger output of compressed air to the pneumatic tool without causing a lack of electric power for driving the compressor unit. As a result, it is possible to avoid interruption of the work performed by the pneumatic tool. Therefore, productivity can be improved.
- The compressor unit may include an air-compressing device and a battery serving as a power source for driving the air-compressing device. With this arrangement, it is possible to use the air-compressing device at a place where no AC power source is available. In this way, the workability can be improved. In addition, the battery of the external tank unit and the battery of the compressor unit can be used simultaneously or exchangeably for driving the air-compressing device.
- In the case where the battery of the external tank unit and the battery of the compressor unit are interchangeably used for driving the air-compressing device, one of the batteries can be recharged or replaced with another battery during driving of the air-compressing device by the other battery. Therefore, it is possible to operate the air-compressing device continually for a longtime in a manner similar to the case where an AC power source is used.
- The external tank unit may include a battery charger capable of charging the battery of the external tank unit. With this arrangement, it is possible to charge the battery of the external tank unit without needing to remove the battery from the external tank unit. Therefore, the operability of the air compressor can be improved.
- The external tank unit may be configured to be able to connect an electric device that is a different device from the compressor unit, so that electric power can be supplied from the battery of the external tank unit to the electric device. In this way, it is possible to further improve the usability of the external tank unit and the air compressor.
- The battery of the external tank unit may be removably mounted to the external tank unit. With this arrangement, it is possible to replace the battery with another battery or to recharge by a separate battery charger.

Thecompressor unit 10 may include apower switch 22, so that electric power may be supplied from theinternal battery 16 to theelectric motor 13 when thepower switch 22 is switched on. Theinternal battery 16 can be removed from thecompressor unit 10 for recharging by a charger (not shown) provided separately from thecompressor unit 10, so that theinternal battery 16 can be used repeatedly. - The
compressor unit 10 may further include apower input terminal 23.

device 14 may be stored in astorage tank 17. Apressure sensor 18 may detect the pressure of the compressed air stored in thestorage tank 17 and may output a detection signal that may be input to thecontrol circuit 15. When the pressure of the compressed air within thestorage tank 17 becomes lower than a predetermined value, thecontrol circuit 15 may output a control signal to theelectric motor 13, so that thestorage tank 17 can be replenished with compressed air. - The compressed air stored within the
storage tank 17 may be regulated to a given pressure by apressure regulator 19. The compressed air having the regulated pressure may be discharged from anair coupler 20 that serves as an air outlet of thecompressor unit 10. Apressure gauge 21 may detect the pressure of the compressed air discharged from theair coupler 20. Thepressure gauge 21 may have a display that can display the detected pressure. The compressed air discharged from theair couple 20 may be supplied to theexternal tank unit 30 via theair hose 11 that is connected to theair coupler 20. - The

The compressed air supplied from thecompressor unit 10 to theexternal tank unit 30 via theair hose 11 may be stored in astorage tank 32. The compressed air stored in thestorage tank 32 may be regulated to a given pressure by apressure regulator 33 and may then be discharged from theexternal tank unit 30 via anair coupler 34. Theair coupler 34 may be connected to the pneumatic tool T via an air hose, so that the compressed air discharged from theexternal tank unit 30 may be supplied to the pneumatic tool T.A pressure gauge 35 may detect the pressure of the compressed air discharged from theair coupler 34. Thepressure gauge 35 may have a display that can display the detected pressure.

external battery 37 of theexternal tank unit 30 may be supplied to thecompressor unit 10 via apower output terminal 38 and thepower cord 12. In this way, theexternal battery 37 can be used as a power source for thecompressor unit 10. Also, theexternal battery 37 can be removed from theexternal tank unit 30 for recharging by a separate charger, so that theexternal battery 37 can be repeatedly used. - The
control circuit 15 may monitor the residual power level of theinternal battery 16 and also the residual power level of theexternal battery 37. When the residual power level of either theinternal battery 16 or theexternal battery 37 becomes less than a given level, thecontrol circuit 15 may automatically switch the supply of electric power to theelectric motor 13 from one to the other of thebatteries - The
compressor unit 10 may be used without theexternal tank unit 30. In such a case, theexternal tank unit 30 may be disconnected from thecompressor unit 10. In this situation, only theinternal battery 16 can be used as a power source. Theair coupler 20 may be connected directly to the pneumatic tool T via theair hose 11. Therefore, the compressed air stored within thestorage tank 17 may be directly supplied to the pneumatic tool T. If the supply of compressed air from thecompressor unit 10 is insufficient, the user can connect theexternal tank unit 30 to thecompressor unit 10. - As described above, according to the air compressor 1 of the first embodiment, the
external tank unit 30 can be connected to thecompressor unit 10. In this embodiment, thecompressor unit 10 has theinternal battery 16 and can be used by itself (without the external tank unit 30). By connecting theexternal tank unit 30 to thecompressor unit 10, it is possible to supply a larger output of compressed air to the pneumatic tool T. In addition to or alternative to theinternal battery 16, theexternal battery 37 can be used as a power source for theelectric motor 13. Therefore, it is possible to use the air compressor 1 for a long time without causing a lack of supply in electric power. As a result, the user can efficiently perform the work using the pneumatic tool T without interruption during use. - The first embodiment can be modified in various ways. For example, in the first embodiment, the pneumatic tool T is connected to the
external tank unit 30 having thestorage tank 32. In this way, the compressed air stored in thestorage tank 32 can be used for driving the pneumatic tool T. Thus, theexternal tank unit 30 is used as an auxiliary tank for thecompressor unit 10. However, anair compressor 50 according to a second embodiment shown inFIG. 2 is configured such that the pneumatic tool T may be connected to thecompressor unit 10 and anexternal tank unit 60 serving as an expansion tank may be connected to theconnector body 10. - In the case of the second embodiment, the
external tank unit 60 may be connected to thestorage tank 17 of thecompressor unit 10 via anair hose 51. The pneumatic tool T may be connected to theair coupler 20 of thecompressor unit 10. In another aspect, thecompressor unit 10 may be configured to be the same as that of the first embodiment. Therefore, inFIG. 2 , like members are given the same reference numerals as the first embodiment and the description of these members will not be repeated. - The
external tank unit 60 of the second embodiment may be substantially the same as theexternal tank 30 of the first embodiment except that theexternal tank unit 60 does not include thepressure regulator 33, theair coupler 34 and thepressure gauge 35. Theexternal tank unit 60 may include anair coupler 61 for connection with anair hose 51 and may further include apower output terminal 62 for connection with thepower cord 12. - One end of the
air hose 51 may be connected to thestorage tank 17 of thecompressor unit 10 via an air coupler (not shown). The other end of theair hose 51 may be connected to astorage tank 63 of theexternal tank unit 60 via theair coupler 61. In this way, thestorage tank 17 of thecompressor unit 10 and thestorage tank 63 of theexternal tank unit 60 may be connected to each other via theair hose 51. Therefore, the compressed air produced at the air-compressingdevice 14 of thecompressor unit 10 may be stored in both thestorage tank 17 of thecompressor unit 10 and thestorage tank 63 of theexternal tank unit 60. - The
external tank unit 60 may have anexternal battery 64 connected to thepower output terminal 62, so that electric power can be supplied from theexternal battery 64 to thecompressor unit 10 via thepower cord 12. Theexternal battery 64 may be removed from theexternal tank unit 60 for recharging by a charger, so that theexternal battery 64 can be repeatedly used. - With the
air compressor 50 according to the second embodiment, theexternal tank unit 60 can be connected to thecompressor unit 10. Thecompressor unit 10 has theinternal battery 16 and can be used by itself (without the external tank unit 60). By connecting theexternal tank unit 60 to thecompressor unit 10, it is possible to supply a larger output of compressed air to the pneumatic tool T. In addition to or alternative to theinternal battery 16, theexternal battery 64 can be used as a power source for theelectric motor 13. Therefore, it is possible to use theair compressor 50 during a long time without causing a lack of supply in electric power. As a result, the user can efficiently perform work using the pneumatic tool T without any significant interruption. - As described above, in the case of the second embodiment, the pneumatic tool T may be directly connected to the
compressor unit 10. Therefore, theexternal tank unit 60 serves as an expansion unit for supplementing the storage capacity of thestorage tank 17. - The second embodiment may be further modified.
FIG. 3 shows an air compressor including anexternal tank unit 70 according to a third embodiment. Theexternal tank unit 70 is a modification of theexternal tank unit 30 of the first embodiment and may be used in combination with thecompressor unit 10 as described in the first embodiment. - The
external tank unit 30 of the first embodiment has theexternal battery 37 that can be removed for recharging by a charger that may be provided separately from theexternal tank unit 30. In contrast, theexternal tank unit 70 of the third embodiment includes acharger 39 that can recharge theexternal battery 37. Therefore, it is not necessary to remove theexternal battery 37 for the purpose of recharging. In this way, it is possible to improve the operability of the air compressor. Thecharger 39 may be connected to an external AC power source, such as an electric outlet (not shown), via a suitable connector. - In addition, as shown in
FIG. 3 , theexternal tank unit 70 may have an additionalpower output terminal 40. An external electric device K may be connected to the additionalpower output terminal 40. In this way, theexternal battery 37 can be used as a DC power source for the external electric device K. Therefore, it is possible to further improve the usability of theexternal tank unit 70 and the air compressor 1. The external electric device K may be lighting equipment, AV equipment such as a radio or a television, cooking equipment such as a coffee maker or an electric pot, a dust collector, a fan, a blower or any other electric device. - The above embodiments may be further modified. For example, an AC power source may be use for the
compressor unit 10 in place of theinternal battery 16. - The
storage tank 17 may be omitted from thecompressor unit 10. In the case that thestorage tank 17 is omitted from thecompressor unit 10 in the first embodiment or the third embodiment, the entire amount of compressed air produced by the air-compressingdevice 14 may be stored in thestorage tank 32 of theexternal tank unit 30. The compressed air is supplied from the air-compressingdevice 14 to thestorage tank 32 via theair hose 11. In the case that thestorage tank 17 is omitted from thecompressor unit 10 in the second embodiment, the compressed air produced at the air-compressingdevice 14 may be initially stored in thestorage tank 63 of theexternal tank unit 60 and then may be supplied to the pneumatic tool T via thecompressor unit 10 when needed. - Further, in the above embodiments, when the residual power level of either the
internal battery 16 or theexternal battery 37 becomes less than a given level, thecontrol circuit 15 may automatically switch the supply of electric power to theelectric motor 13 from one to the other of thebatteries compressor unit 10 such that theinternal battery 16 and theexternal battery 37 may be simultaneously used as power sources. - As noted above, an AC power source may be use for the
compressor unit 10 in place of theinternal battery 16. In the case that an AC power source is used, theexternal battery 37 of the external tank unit 30 (60, 70) may be used as an auxiliary power source in the event that the supply of the AC power is interrupted because of the power outage or some other reason. - Further, the
compressor unit 10 without thestorage tank 17 can be used by itself when theexternal tank 30 is disconnected. In such a case, the compressed air produced by the air-compressingdevice 14 may be directly supplied to the pneumatic tool T via theair hose 11. In this case, a sufficient output of compressed air can be supplied to the pneumatic tool T as long as the pneumatic tool T is used for a relatively light duty work. - Finally, although not defined in the claims, the following teachings A and B are also disclosed in the present application:
