Description:FIELD OF THE INVENTION
[0001] The subject matter of present invention generally relates to a cooling apparatus. In particular, the subject matter relates to table top fan to create a flow of cool air. The table top fan comprises a peltier module to create peltier effect in liquid available in the liquid reservoir. The table top fan further comprises a mist generating chambers having a plurality of piezo electric ultrasonic atomizers to create mist of cool and fine liquid particles that is unanimously mix with air stream within the air cooling apparatus.

BACKGROUND OF THE INVENTION
[0002] Background description includes information that may be useful in understanding the present subject matter.
[0003] A traditional fan consists of a rotating arrangement of vanes or blades, generally made of wood, plastic, or metal, which act on the air by receving the air from back side and through the air towards front of the fan. The rotating assembly of blades and hub is known as an impeller, rotor, or runner. This may direct the airflow, or increase safety by preventing objects from contacting the fan blades. Most fans are powered by electric motors, but other sources of power may be used, including hydraulicmotors, handcranks, and internal combustion engines.
[0004] In pedestal fan or table fan, an air cooling apparatus is provided by means of high pressure water supply system which allows passage of high pressure water through a plurality of spray nozzles to spread water droplets in environment to achieve cooling effect. In these kind of systems, a water reservoir or liquid reservoir is provided at the bottom and has a high pressure pump to supply high pressure water to the spray nozzles provided in front of the air blow unit.
[0005] Other existing table top coolers are working on the principle to generate vapours of water for generating cooling effect which requires cooling pad for evaporation of water and a water pump to supply water to all cooling pads. The evaporative coolers work efficiently during hot conditions and have bad impact on health during humidity conditions.
[0006] Technical problem associated with the above fan units is the cost of pressure pump and running cost of the pressure pump. Another technical problem associated with the existing fan unit is water droplets size which is big that create moisture in the environment and threat of corrosion to surrounding components prone to rust. A high speed fan blades should always be maintained in such kind of fans to through the water droplets with air and keep them work properly.
[0007] Another technical problem associated with the existing fan unit during humid days is that water droplets remain on the human body to increase discomfort and increase heat index. The impact of humidity is discomfort which can result in to fatigue, dehydration, muscle cramp, etc., to humans.
[0008] Another technical problem associated with the existing fan unit is wastage of water or liquid.
[0009] Accordingly, the existing fan unit are not efficient in terms of cooling for long time and comfortable cooling to human beings.
[0010] There is need in the art to provide a system that can eliminate the above mentioned technical problems with less manufacturing and operational cost and provides better cooling effects.

Furthermore, repeated use of the phrase “in an embodiment” does not necessarily refer to the same embodiment.
[0037] When the terms “front”, “rear”, “top”, “bottom”, “inner”, “outer”, “side”, and similar terms are used herein, it should be understood that these terms have reference only to the structure shown in the drawings as it would appear to a person viewing the drawings and are utilized only to facilitate describing the invention, rather than restricting the invention.
[0038] Referring to Fig. 1, 2 and 3, the present invention illustrates a table top mist fan assembly (100). The assembley (100) comprises a fan blower (104) having blades which are inclined at a particular angle and rotates in one way to suck the air from its rear side and through the sucked air towards its front side in a direction of an air vent grill (108). The angle of inclination on the fan blades may be varied to determine the amount of air blown forward. If it is inclined more steeply, it blows more air but has a lot of drag and requires more power. If inclined more subtly, it requires lesser power to turn faster but subsequently reduces the amount of air that it blows out. The further assembley (100) comprises a water reservoir (130) which is provided beneath the fan blower (104) to store water inside the water reservoir (130).
[0039] A Thermoelectric cooling system based on Peltier Effect is used through which the required heat transfer can be achieved. As according to the present invention, a cooling junction (138) of the peltier module (128) coupled to a wall of the water reservoir (130) in order to make the water cool which is available in the water reservoir (130). Further, the heat is absorbed and disseminated in environment and keep the water cool which is available in the water reservoir (130). Such effect is achieved by passing an electric current through the pletier module.
[0040] Such that the Peltier module (thermoelectric module) has both "warming" and "cooling" effects. A Peltier module or thermoelectric module is a solid-state active heat pump which consist a number of p- and n- type semiconductor couples connected electrically in series and thermally in parallel are sandwiched between two thermally conductive and electrically insulated substrate. The Peltier module transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current. When operated as a cooler, a voltage is applied across the device, and as a result, a difference in temperature will build up between the two sides so that one side gets cooler while the other gets hotter.
[0041] The assembly (100) further comprises a mist generator (114) mounted on a floor of the water reservoir (130) to generate mist from the stored water. The cold mist is generated in a mist chamber (110) by the cold water stored in the water reservoir (130) wherein the mist chamber (110) coupled with the mist generator (114) via a mist chamber extension (112).
