(a) TECHNICAL FIELD OF THE INVENTION

The present invention generally relates to an air conditioning device, and more particularly to an air conditioning device that comprises a structure for circulative re-use of condensed water thereof.

(b) DESCRIPTION OF THE PRIOR ART

To improve heat exchange performance of a movable air conditioning device, circulative re-use of water condensed in the air conditioning device is a feasible solution. Heretofore, a movable air conditioning device uses the condensed water in either one of the following ways. The first way of using the condensed water is to use a water pump that is arranged in a water collection tray to pump water to a condenser for re-use of the water. The second way is to use a shaded pole electric machine to drive vane wheel for spread water as droplets that are sprayed over a condenser so as to realize the re-use of the condensed water. Both arrangements of re-use of condensed water are effective in improving heat exchange performance of the movable air conditioning device. However, the costs of re-using condensed water with these ways are high and the waste of resources is severe.

The driving electric machine functions as an electric machine 1 for the air conditioning device. The water pumping device comprises a cylinder 29, and the cylinder 29 forms therein a water inlet chamber 30, a water outlet chamber 31, and a piston chamber 32. The piston chamber 32 is defined by an upper piston retention board 6 and a lower piston retention board 7. The piston chamber 32 receives therein a piston 5, which is coupled to the transmission mechanism. The water inlet chamber 30 and the piston chamber 32 communicate each other through a water inlet piston 9, while the water outlet chamber 31 and the piston chamber 32 communicate each other through a water outlet piston 12. The water inlet chamber 30 comprises a water inlet port 8, which communicates the water collection tray 18 through a water inlet pipe 14. The water inlet chamber 30 is sealed by a water inlet chamber plug 10 and the water outlet chamber 31 is sealed by a water outlet chamber plug 11. Further, the water outlet chamber 31 comprises a water outlet port 13, which communicates the water spraying tray 16 through a water outlet pipe 15.

As shown, the transmission mechanism comprises a crank 2 that is mounted to a shaft of the electric machine 1 and a connection rod 4 that is rotatably coupled to the crank 2 through a bearing 3. The connection rod 4 has an end coupled to the piston 5.

The operation of the first embodiment is as follows. The electric machine 1 drives the crank 2 and the connection rod 4 to produce reciprocal movement of the piston 5. When the piston 5 reaches a highest position, water contained in the water collection tray 18 that is located at the bottom is conveyed through the water inlet pipe 14, the water inlet port 8, and the water inlet piston 9 to flow into the cylinder. When the piston 5 reaches a lowest position, the water received in the cylinder moves through the water outlet piston 12, the water outlet port 13, and the water outlet pipe 15 to reach the water spraying tray 16 from which the water is sent to a condenser to increase the heat exchange rate of the air conditioning device. In the course of the operation of the electric machine, this process is cyclically repeated.

Referring to FIGS. 5-10, which are respectively a front view, partially broken, showing a second embodiment of the present invention, a rear side cross-sectional view showing the second embodiment, a perspective view, partially broken, showing the second embodiment, a left side cross-sectional showing the second embodiment, a cross-sectional view showing details of a portion of the second embodiment, and another cross-sectional view showing details of a portion of the second embodiment, as shown, a condensed water utilization structure of air conditioning device according to the second embodiment of the present invention is constructed substantially the same as the condensed water utilization structure of the first embodiment shown in FIGS. 1-4, and a difference resides in that the transmission mechanism of the second embodiment comprises a first transmission roller 19 that is mounted to a shaft of the electric machine 1, a second transmission roller 21 that is coupled to the first transmission roller 19 by a first transmission belt 20, a third transmission roller 25 that is coupled to the second transmission roller 21 through a transmission shaft 22, a fourth transmission roller 27 that is coupled to the third transmission roller 25 by a second transmission belt 26, a crank 2 that is mounted to a shaft of the fourth transmission roller 27, and a connection rod 4 that is rotatably coupled to the crank 2. The connection rod 4 has an end coupled to the piston 5. The transmission shaft 22 that couples the second transmission roller 21 and the third transmission roller 25 is mounted inside the air conditioning device through bearings 23, 24.

The operation of the second embodiment is as follows.

When the piston 5 reaches a highest position, water contained in the water collection tray 18 that is located at the bottom is conveyed through the water inlet pipe 14, the water inlet port 8, and the water inlet piston 9 to flow into the cylinder. When the piston 5 reaches a lowest position, the water received in the cylinder moves through the water outlet piston 12, the water outlet port 13, and the water outlet pipe 15 to reach the water spraying tray 16 from which the water is sent to a condenser to increase the heat exchange rate of the air conditioning device. In the course of the operation of the electric machine, this process is cyclically repeated.

Referring to FIGS. 11-15, which are respectively a rear side cross-sectional view showing a third embodiment of the present invention, a left side cross-sectional view showing the third embodiment, a perspective view, partially broken, showing the third embodiment, a cross-sectional view showing details of a portion of the third embodiment, and another cross-sectional view showing details of a portion of the third embodiment, as shown, a condensed water utilization structure of air conditioning device according to the third embodiment the present invention is constructed substantially the same as the condensed water utilization structure of the first embodiment shown in FIGS. 1-4, and a difference resides in that the driving electric machine comprises a synchronous electric machine 28 and the transmission mechanism comprises a crank 2 that is coupled to the synchronous electric machine 28 and a connection rod 4 that is rotatably coupled to the crank 2. The connection rod 4 has an end coupled to a piston 5.

The operation of the third embodiment is as follows. The synchronous electric machine 28 drives the crank 2 and the connection rod 4 to produce reciprocal movement of the piston 5. When the piston 5 reaches a highest position, water contained in a water collection tray 18 that is located at the bottom is conveyed through a water inlet pipe 14, a water inlet port 8, and a water inlet piston 9 to flow into a cylinder. When the piston 5 reaches a lowest position, the water received in the cylinder moves through a water outlet piston 12, a water outlet port 13, and a water outlet pipe 15 to reach a water spraying tray 16 from which the water is sent to a condenser 17 to increase the heat exchange rate of the air conditioning device. In the course of the operation of the electric machine, this process is cyclically repeated.

It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.
