Description

TITLE: COMPRESSING SYSTEM FORAUTOMOBILE AIR
CONDITIONER
(a) Technical Field of the Invention
The present invention is generally related to automobile air conditioners, and more particular to a compressing system for automobile air conditioners which is actuated by electrical pOwer.
(b) Description of the Prior Art
As illustrated in FIGS. 1 and 2, a conventional compressing system for an automobile air conditioner contains a compressor A, an electromagnet B, a belt-driven wheel C, and a clutch dial D. A shaft Al is extended outside the compressorA and is threaded through the electromagnet 13 which is joined to a front side of the compressor A. The wheel C is joined to a front side of the electromagnet B by a bearing (not shown) so that the wheel C is freely rotatable. The clutch dial D is joined to a front side of the *heel C and has axial tube Dl threading sequentially through the wheel C and the electromagnet B. For this conventional compressing systcm to function, an external driving device (eg., the automobile engine) E is required as the power source. A belt F sunounds a driving wheel El of the external driving device E and the wheel C. When the automobile air conditioner is turned on, electricity is conducted through the electromagnet B to produce a magnetic field to draw the clutch dial D tightly to the wheel C. In the meantime, the axial tube Dl couples the shaft Al of the compressor A. As the external driving device B drives the wheel C to spin through the belt F, the clutch dial D is rotated as well. Then, through the clutch dial D's engaging the shaft Al, the compressor Ais actuated.
in other words, iii the conventional compressing system described above, the external driving device E is the main power source, which would consume additional thel and produce more carbon dioxide, especially when the automobile is idle with the air conditioner being turned on. As the oil price continuously rises and as people are more concerned of the global warming, an environmentally friendlier compressing system is required.
SUMMARY OF THE INVENTION
Therefore, a novel compressing system for automobile air conditioners is provided herein, which is actuated by electricity without changing the conventional compressor.
The compressing system contains a compressor having a shall extended outside the compressor; and a driving device configured outside the compressor. The driving device contains a stator and a rotor. The stator is joined to the compressor, and has at least two wires for connecting an external power source. The mtor is configured around the stator, and has an accommodation space for housing the statoi and an axial connection tube is configured at the center of the accommodation space. The shaft of the compressor is threaded and joined to the connection tube. By conducting electricity thmugh the stator and producing directional magnetic fields, the rotor interacts with the directional magnetic fields to produce rotational torque to spin the rotor. As such, the shaft is turned as well and the compressor is actuated. In contrast, a conventional automobile air conditioner compressor is actuated by the automobile engine, which consumes addition ftiel of the automobile, and therefore increases the production of carbon dioxide, a major cause to the global greenhouse effect.
The foregoing objectives and summary provide only a brief introdu ction to the present invention. To frilly appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIIvIENTS The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of thc invention as set forth in the appended claims.
As illustrated in FIGS. 3 and 4, a compressing system for an automobile air conditioner according to a first embodiment of the present invention contains a compressor I and a driving device 2. The compressor I can be conventional compressor for automobile air conditioners and the present invention does not require modification to the internal structure of the compressor 1.
The compressor 1 has a shaft 11 extended outside the compressor 1. The compressor 1 can be a p15 ton reciprocating compressoi plate recipmcating compressor, a mtary vane compressoi etc. The driving device 2 is powered by electricity and is configured outside the compressor 1. In the present embodiment, the driving device 2 is an external rotor motor and contains a stator 21 and a rotor 22.
The stator 21 has an axial channel 211 through which the shaft 11 of the compressor I is threaded so that the stator 21 is joined to a front side of the compressor 1. The stator 21 has at least two wires 212 for connecting the terminals of opposite polarities of an external power source (such as a battery of the automobile or other power source). The staler 21 contains a coil-wound iron core and the coils are connected to the wires 212. As such, electricity from the external power source flows through the coils and the stator 21 produces directional (clockwise or counterclockwise) magnetic fields.
The rotor 22 is configured around the stator 21. The rotor 22 has an accommodation space 221 for housing the stator 21. Around an internal wall of the accommodation space 221, a number of magnetic elements 222 are configured. Therefore, the magnetic elements 222 are positioned around an outer circumference of the stator 21. At the center of the accommodation space 221, an axial connection tube 223 is configured. The connection tube 223 is plugged into the axial channel 211 of the stator 21, and the shaft 11 of the compressor 1 is threaded and joined to the connection tube 223 of the rotor 22.
When the automobile air conditioner is turned on and the compressing system is started, electricity is conducted through the coils of the stator 21 of the driving device 2 arid directional magnetic fields are produced. The magnetic elements 222 of the rotor 22 interact with the directional magnetic
S
fields to produce rotational torque to spin the mtor 21. As such, the shaft ii of the compressor 1 is turned as well and the compressor 1 is actuated. In other words, the compressor 1 is actuated by electrical power, unlike conventional automobile air conditioner compressor which is actuated by the automobile engine. The latter consumes addition thel of the automobile, and therefore increases the production of carbon dioxide, which is a major cause to the global greenhouse effect.
As illustrated in FIGS. 5 to 7, a compressing system for an automobile air conditioner according to a second embodiment of the present invention contains a compressor 1 and a driving device 3. The driving device 3 is powered by electricity and is configured outside the compressor 1. In the present embodiment, the driving device 3 is an external rotor motor and contains a stator 31 and a rotor 32.
The stator 31 has an axial space 311 through which the shaft 11 of the compressor 1 is threaded so that the stator 31 is joined to a fltnt side of the compressor 1. The stator 31 has at least two wires 312 for connecting the temilnals of opposite polarities of an external power source (such as a battery of the automobile or other power source). The stator 31 contains a coil-wound iron core and the coils are connected to the wires 312. As such, electricity from the external power source flows through the coils and the stator 31 produces directional (clockwise or counterclockwise) magnetic fields.
The rotor 32 is a magnetic element, and is housed in the axial space 311 of the stator 31. The rotor 32 is threaded by and joined to the shaft 11 of the compressor I. When the automobile air conditioner is turned on and the compressing system is started, electricity is bonducted through the coils of the stator 31 of thc driving device 3 and directional magnetic fields are produced. The rotor 32 interacts with the directional magnetic fields to pmduce rotational torque to spin the rotor 31. As such, the shall 11 of the compressor 1 is turned as well and the compressor 1 is actuated. Again, the compressor 1 is actuated by electrical power, unlike conventional automobile air conditioner compressor which is actuated by the automobile engine.
The external power source can he the automobile's major battery or an additionally configured auxiliary battery. The wires 212 or 312 from the driving device 2 or 3 therefore can be connected to the major battery or the auxiliary battery of the automobile.
As described above, the gist of the present invention lies in the configuration of electrically powered driving device outside the compressor for the actuation of the compressor. As such, unlike conventional automobile air conditioner compressoi the present invention does not consume addition thel of the automobile, and therefore does not increase the production of carbon dioxide, which is a major cause to the global greenhouse effect.
While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will he understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing hi any way from the spirit of the present invention,
