Regulation 3.2 AUSTRALIA PATENTS ACT 1990 COMPLETE SPECIFICATION FOR AN INNOVATION PATENT ORIGINAL Name of Applicant: New Widetech Industries Co., Ltd. Actual Inventor: Ming-Tsung Chiu Address for Service: C/- MADDERNS, Level 4, 19 Gouger Street, Adelaide, South Australia, Australia Invention title: CONDENSER WITH A NEBULIZER HAVING A LOW-VOLTAGE DIRECT CURRENT MOTOR The following statement is a full description of this invention, including the best method of performing it known to us.

1la 1. Field of the Utility model The present utility model relates to a condenser, especially to a 5 condenser with a nebulizer having a low-voltage direct current motor. 2. Description of the Prior Arts An air conditioner utilizes thermal dynamics to cool indoor temperature. When the air conditioner operates, water is condensed from air and needs to be drained out of the air conditioner. Generally, water is drained out through a pipe. 10 However, the outlet of the pipe must be directly connected to a drain or drip freely. When connected to the drain connecting tubes are used and may be revealed or concealed. Revealed connecting tubes reduce aesthetic appeal of a building, but concealed connecting tubes should be built during original construction; otherwise expensive renovation is required. 15 To overcome the shortcomings, the present utility model provides a condenser with a nebulizer having a low-voltage direct current motor to mitigate or obviate the aforementioned problems. The main objective of the present utility model is to provide a condenser with a nebulizer having a low-voltage direct current motor. The condenser is 20 designed for air conditioners to replace draining condensed water. The condenser has a body mounted on the seat, a nebulizer and a nebulizing disk. The body has two condensing units. An open space is formed between the condensing units. The nebulizer is mounted beside the body and has a low-voltage direct current motor and a shaft. The shaft is driven by the low-voltage direct current motor and 2 protrudes into the open space. The nebulizing disk is mounted securely around the shaft and is mounted in the open space. When the low-voltage direct current motor operates, the rotated nebulizing disk nebulizes condensed water in the seat to the condensing units. Heat of the condensing units vaporizes condensed water 5 that is easily discharged without requiring pipes or draining. Therefore, the air conditioner with the condenser needs no outside tubes. Further, the low-voltage direct current motor is highly efficient, has fast rotational speed so is energy saving and safe. Other objectives, advantages and novel features of the utility model will 10 become more apparent from the following detailed description when taken in conjunction with the accompanying drawings. Fig. 1 is a perspective view of a condenser with a nebulizer having a low-voltage direct current motor in accordance with the present utility model; Fig. 2 is an exploded perspective view of the condenser in Fig. 1; 15 Fig. 3 is an exploded perspective view of a nebulizing disk of the nebulizer in Fig. 1; and Fig. 4 is a top view of the condenser in Fig. 1. With reference to Figs. 1 and 2, a condenser with a nebulizer having a low-voltage direct current (DC) motor in accordance with the present utility 20 model comprises a base (10), a body (20), a bracket (30), a nebulizer (40) and a nebulizing disk (50). The base (10) has a seat (11). The body (20) is mounted in the seat (11) and has two condensing units (21) and multiple condensing tubes (22). The condensing units (21) are mounted 3 separately in the seat (11). An open space is formed between the condensing units (21). The condensing tubes (22) are mounted respectively through the condensing units (21). The bracket (30) is mounted on the base (10) and is mounted beside the 5 body (20). With further reference to Fig. 3, the nebulizer (40) is mounted on the bracket (30) and comprises a low-voltage DC motor (41) and a shaft (42). The low-voltage DC motor (41) is attached securely to the bracket (30). The shaft (42) is connected to and is driven by the low-voltage DC motor, is mounted through 10 the bracket (30) and protrudes into the open space between the condensing units (21). With further reference to Fig. 4, the nebulizing disk (50) is mounted securely around the shaft (42) and is mounted in the open space between the condensing units (21). The nebulizing disk (50) may be a volute centrifugal disk, 15 a hydraulic wheel or the like to nebulize water. In use the condensed water inside the air conditioner flows to the seat (11). The low-voltage DC motor (41) drives the shaft (42) to rotate the nebulizing disk (50). The rotating nebulizing disk (50) nebulizes the condensed water from the seat (11) and guides the condensed water to the condensing units 20 (21). Heat of the condensing units (21) vaporizes the condensed water. Since vaporized water is easily discharged, the air conditioner with the condenser as described does not need pipes and easily discharges condensed water. Furthermore, using the low-voltage DC motor has following advantages. 1. Compared to an alternating current (AC) motor, a low-voltage DC 4 motor (41) occupies only 20% volume of the AC motor. Therefore, materials to manufacturing the low-voltage DC motor (41) is reduced. 2. The power consumption of the AC motor is about 15 to 20 watt, compared to about 2 to 3 watt for the low-voltage DC motor (41). Therefore, the 5 low-voltage DC motor (41) is energy saving. 3. The low-voltage DC motor (41) drives the nebulizing disk (50) to nebulize water into drops. Higher rotational speeds reduce average volume of nebulized drops; smaller drops also vaporize more easily. The rotational speed of the AC motor is about 2500 to 3000 rpm, compared to about 3500 to 5000 rpm 10 for the low-voltage DC motor (41). 4. Since the low-voltage DC motor (41) uses voltage lower than 36 volts, danger of electrocution is reduced. Therefore, the low-voltage DC motor (41) enhances the efficiency of heat dissipation of the air conditioner with the condenser as described, reduces 15 energy usage and improves efficiency of the condenser as described. Even though numerous characteristics and advantages of the present utility model have been set forth in the foregoing description, together with details of the structure and features of the utility model, the disclosure is illustrative only. Changes may be made in the details, especially in matters of 20 shape, size, and arrangement of parts within the principles of the utility model to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
