Patents Act 1990 INNOVATION SPECIFICATION FOR AN INVENTION ENTITLED Invention title: Name of Applicant: Address for Service Single Centrifugal Wind Wheel Airconditioner Mao-Tsai Ku A.P.T. Patent and Trade Mark Attorneys PO Box 222 Mitcham, S.A. 5062 The invention is described in the following statement: 0 SINGLE CENTRIFUGAL WIND WHEEL AIR CONDITIONER BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to an air conditioning device, and more particularly to a single centrifugal wind wheel air conditioner that saves on material cost and conserves energy.

00 Description of the Prior Art N Air-conditioning systems are of widespread use in present households and offices, and air conditioners are usually separated into split type air conditioners and one piece air conditioners according to configuration.

The split type air conditioner includes an indoor unit and an outdoor unit, working principle of which is based on the entire condenser system transferring a quantity of heat along a passageway to the outdoor unit, where the quantity of heat is dispersed outside the room while refrigerating the interior of the room. Accordingly, both the indoor unit and the outdoor unit need a fan to implement cold or heat dispersion.

Whereas, a one piece air conditioner is mounted in a window defined in a wall, in which the indoor unit and the outdoor unit is a single body configuration, however, orientation is different. The indoor unit faces 0 indoors, while the outdoor unit faces outside. Moreover, some companies have developed a portable air conditioner which can be moved around, and such portable air conditioners can be moved to locations requiring use thereof according to user needs, thereby providing high mobility, and realizing maximum use efficiency for locations requiring temporary use of an air conditioner, such as temporary conference rooms.

00 However, when using the aforementioned air conditioners, the r'l following existing problems and shortcomings are still clearly awaiting improvement: Split type air conditioning devices of prior art require two motors to actuate two wind wheels connected to two air ducts which respectively blow cold air to the interior of a room and discharge hot air outside the room, whereas the one piece air conditioning device of prior art mounted in a window requires one or two motors connected to two wind wheels and two air ducts which respectively blow cold air to the interior of a room and discharge hot air outside the room. However, neither the bulk nor material cost of the aforementioned air conditioning devices of prior art can be reduced. Moreover, especially in spaces infrequently used, such as temporary conference rooms, frequency of use of an 0 installed air conditioner is low, and is unable to guarantee air conditioning effectiveness during temporary use.

Furthermore, a dehumidifying function is configured in the air conditioning devices of prior art; however, the dehumidifier mode of the air conditioning devices can only be used intermittently to achieve the dehumidifying objective. For example, after the air conditioning device has been running for 10 minutes, then it stops for 4 minutes, and so on, 00 and adopts a cycling mode of operation to achieve the dehumidifying r'l function, at which time the air conditioning device implements refrigeration, thus, a portion of the ambient temperature will fall along with refrigeration of the air conditioning device, and Is unable to achieve true dehumidifier functionality of existing technology.

Moreover, both the cold air outlet and hot air outlet of the portable air conditioner of prior art require a motor and an air duct, and two air inlets and the cold air outlet are equally positioned inside a room, thus, when the portable air conditioner is operating, the air inlets draw in processed cold air from inside the room, and cold air is discharged out the hot air outlet, thereby resulting in low air conditioning efficiency.

Hence, the inventor of the present invention and manufacturers engaged in related art propose to resolve and surmount existent 0 technical difficulties to eliminate the problems and shortcomings of the aforementioned prior art.

SUMMARY OF THE INVENTION Hence, in light of the shortcomings of the aforementioned prior art, the inventor of the present invention, having accumulated years of experience in related arts, and through continuous testing and improvements, has developed a new improved structure for a single 00 centrifugal wind wheel air conditioner.

r' A primary objective of the present invention is to provide a single centrifugal wind wheel air conditioner which comprises a hot air outlet and a cold air outlet, moreover, the air conditioner is further configured with a wind wheel and an air duct. The wind wheel is actuated by a preinstalled motor, and the hot air outlet and the cold air outlet are sequentially configured to the air duct. A refrigeration system is also disposed in the air conditioner, and the refrigeration system comprises a refrigerating end and a heat dissipating end. The refrigerating end is disposed so as to surround the cold air outlet, and the heat dissipating end is disposed so as to surround the hot air outlet. Such a structure only needs one wind wheel to simultaneously achieve discharge of cold air inside a room and the discharge of hot air outside the room, which 0 not only enables reducing bulk and saving on transportation costs and material costs, moreover, with the present day upsurge in energy cost, the use of only one wind wheel increases energy efficiency of the air conditioner and achieves the objective of saving on energy.

A second objective of the present invention lies in: the single centrifugal wind wheel air conditioner configured with a rear cover, a base, an exhaust duct and air inlets configured at two ends, which 00 enable the intake and circulation of air. The exhaust duct enables hot air r' produced to be discharged outside, and the base is used to dispose and support the entire main body thereon. A plurality of rollers are located on the base, and the rollers are used to facilitate movement of the air conditioner, thereby providing high mobility, and enabling the present invention to be used in variety temporary locations, such as temporary conference rooms, and so on. Moreover, the rear cover, the exhaust duct and each of the rollers can be removed, thereby enabling the air conditioner to be used as a window air conditioner, in which the hot air outlet and the air inlet are similarly located exterior of the room, and only the cold air outlet faces the interior of the room. When the air conditioner draws in air, the unrefrigerated outside air undergoes refrigeration processing, thus, does not form a negative pressure space, 0 and increases refrigeration efficiency.

Another objective of the present inventions lies in: the single centrifugal wind wheel air conditioner configured with the hot air outlet and a water collecting portion, and a water drawing motor is disposed to the water collecting portion. The water drawing motor actuates a water drawing wind wheel connected thereto, which is used to raise the condensed water in the water collecting portion to within the hot air 00 outlet, thereby eliminating the need for the single wind wheel air r' conditioning device to additionally connect a water drain pipe, and thus further increasing convenience of the air conditioner.

Yet another objective of the present inventions lies in: the single centrifugal wind wheel air conditioner configured with the cold air outlet, on which is disposed a turnover blade which serves to adjust the direction of cold air. Moreover, the turnover blade may be controlled using an electric control switch, such that when the turnover blade closes the cold air outlet using the electric control switch, then the original air in the cold air outlet flows back along the air duct and mixes with the hot air, after which it is blown out from the hot air outlet.

Accordingly, discharge of the air outside through the hot air outlet prevents the indoor temperature from falling. Moreover, the present 00 00 invention can be used as a dehumidifier.

To enable a further understanding of said objectives and the technological methods of the invention herein, a brief description of the drawings is provided below followed by a detailed description of the preferred embodiments.

Moreover, rollers C8 are disposed on the base C7 and used to further facilitate movement of the single centrifugal wind wheel air conditioner A.

Referring to FIG. 3, which shows a perspective view of the preferred embodiment of the present invention, wherein, because the air coming out of the cold air outlet C1 comes in contact with the refrigerating end 00 D2 of the compressor D1, thus, when refrigerating the air, condensation r'l of the moisture content in the air occurs, accordingly, the single centrifugal wind wheel air conditioner A of the present invention is configured with a water receiving portion C9, for example, a groove, below the refrigerating end D2. Moreover, a water collecting portion C6 is disposed within the base C7 beneath the heat dissipating end D3, and is used to collect the condensed water from the water receiving portion C9. The single centrifugal wind wheel air conditioner A of the present invention further comprises a water drawing motor El disposed to the water collecting portion C6, wherein the water drawing motor El actuates a water drawing wind wheel B7 connected thereto, which is used to raise the condensed water in the water collecting portion C6 to within the hot air outlet C2, thereby eliminating the need for the single 0 wind wheel air conditioner A of the present invention to additionally connect a water drain pipe, and thus further increasing convenience of the air conditioner.

Referring to FIG. 4 and FIG. 5, which show partial schematic views 1 and 2 respectively of the preferred embodiment of the present invention, wherein a connection between a wind wheel B and a motor E can be clearly seen from the drawings, in which the motor E is positioned within 00 the wind wheel B, and the blades of the wind wheel B are separately r' configured as first blades B1 and second blades B2. Diameter of the first blades B1 and the second blades B2 can be freely set according to user requirements to obtain an appropriate air volume. A blade partition B4 can be further located between the first blades B1 and the second blades B2 to form two air ducts, thereby prohibiting mutual passage between hot air and cold air. Furthermore, a retaining device B5 is located on the second blades B2, and the retaining device B5 is used to fix the entire wind wheel B to the motor E.

According to the aforementioned structure and compositional design, use and operating circumstances of the present invention are described as follows. Referring to FIG. 6, which shows a first implementation drawing of the preferred embodiment of the present invention, and it can 0 be clearly seen from the drawing that when the aforementioned components are operating and the wind wheel B is being driven and rotated by the motor E, then the wind wheel B draws in air, at which time centrifugal force transports the air to the hot air outlet C2 and the cold air outlet C1, thereby enabling the single centrifugal wind wheel air conditioner A to realize recirculation of air current.

Referring to FIG. 7, which shows a second implementation drawing of 0 a preferred embodiment of the present invention, wherein the drawing r'l clearly depicts disposition of two air inlets, namely the first air inlet C4 and the second air inlet C5 of the present invention, in which the motor E driving and rotating the wind wheel B causes air to be drawn in through the first air inlet C4 and the second air inlet C5 via different passageways, whereupon centrifugal force causes indoor air to be transported through the cold air outlet C1 to the refrigerating end D2, where refrigeration of the air takes place; and air passing through the hot air outlet C2 is transported to the heat dissipating end D3, where heat is dissipated.

Referring to FIG. 8, which shows a third implementation drawing of a preferred embodiment of the present invention, and it can be clearly seen from the drawing that the present invention can also be configured 0 so that the heat dissipating end D3 is disposed at an outer side of the second air inlet C5, and the refrigerating end D2 is disposed at an outer side of the first air inlet C4. Furthermore, an air partition B6 is disposed within the air duct B3, and disposition of the air partition B6 causes air passing through the refrigerating end D2, under the centrifugal action of the wind wheel B, to pass through the half space separated by the air partition B6 within the air duct B3 and be discharged out the cold air 00 outlet C1, and causes air passing through the heat dissipating end D3, r'l under the centrifugal action of the wind wheel B, to pass through the other half space separated by the air partition B6 within the air duct B3 and be discharged out the hot air outlet C2.

Referring to FIG. 9, which shows a fourth implementation drawing of a preferred embodiment of the present invention, and it can be clearly seen from the drawing that the single centrifugal wind wheel air conditioner A of the present invention allows for the exhaust duct C21, the rear cover C3 of the housing C and the rollers C8 to be removed, after which the single centrifugal wind wheel air conditioner A can be installed to a mounting frame of a window, thereby enabling the present invention to be used as a window type air conditioner.

Referring to FIG. 10 and FIG. 11, which show an implementation 0 drawing and a sectional view respectively of another preferred embodiment of the present invention, and it can be clearly seen from the drawings that the difference between the single centrifugal wind wheel air conditioner A of this embodiment and the aforementioned embodiments lies in the level disposition of the exhaust duct C21 on the hot air outlet C2, and is a configuration suitable for installation where position of the exhaust outlet is relatively low. Moreover, a turnover 00 blade C11 can be further disposed on the cold air outlet C1 of the C' housing C, and the turnover blade C11 can be used to adjust the direction of the cold air and close the cold air outlet C1. The single centrifugal wind wheel air conditioner A of the present invention is also provided with dehumidifying effectiveness, and only requires the cold air outlet C1 to be closed when being used as such. Closure of the cold air outlet C1 can be realized by using the turnover blade C11, or a control switch can be adopted, for example, through electrical control, which is realized by disposing a switch board in the pipeline of the cold air outlet C1. In addition, the single centrifugal wind wheel air conditioner A of the present invention can further comprise a water lifting motor E2 disposed on the water collecting portion C6, and can also be configured with a sensor that is used to sense the catchment water line of the water 0 collecting portion C6.
