ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to an air conditioning apparatus, more particularly to an air conditioning apparatus with a water pump disposed therein and driven by a motor of a blower.
2. Description of the Related Art
A conventional air conditioning apparatus generally has a drain pane disposed in a bottom of a case body thereof for collecting droplets of condensate resulting from the cooling of air stream, and a drain pipe fluidly communicated with an outlet of the drain pane and extending outwardly of the case body for draining water outwardly of the air conditioning apparatus. In this manner, it is difficult to drain the water collected in the drain pane completely. To solve this problem, it has been heretofore proposed to connect a water pump to the air conditioning apparatus. However, the water pump needs to be driven by an additional motor, thereby resulting in an increase in the manufacturing cost. In addition, the water pump is disposed outwardly of the air conditioning apparatus, and affects the outer appearance of the apparatus.
SUMMARY OF THE INVENTION
The object of the present invention is to provide an air conditioning apparatus which includes a water pump disposed therein and driven by a motor of a blower to obviate the need for an additional motor mechanism that can affect the outer appearance of the apparatus.
According to this invention, the air conditioning apparatus includes a case body with a chamber therein, and a front panel defining an opening to communicate with the chamber. An air cooling coil is disposed in the chamber and rearwardly of the front panel, and is adapted to cool an air stream flowing thereacross. A blower is disposed in the chamber and rearwardly of the air cooling coil, end is driven by an output shaft of a motor to blow the air stream across the air cooling coil and deliver cooled air stream forwardly and outwardly of the opening. A drain pane is disposed in the chamber and under the air cooling coil to collect droplets of condensate resulting from cooling of the air stream. The drain pane has a first outlet to drain water therein resulting from collection of the droplets. A water pump includes a pump body with an accommodation chamber, and an impeller which is received in the accommodating chamber, and which is provided with a driven shaft rotatably mounted in the accommodation chamber. The driven shaft extends outwardly of the pump body to form a coupling end which is disposed to be coupled with the output shaft of the motor so as to enable the drive of the motor to drive the impeller to rotate. The water pump has a second inlet which is communicated with the accommodation chamber and upstream of the impeller, and which is in fluid communication with the first outlet of the drain pane, and a second outlet which is communicated with the accommodation chamber and downstream of the impeller so that rotation of the impeller will generate a suction force to drain the water from the first outlet via the second inlet and out of the second outlet.
