FIELD OF INVENTION

The present invention relates to an improved evaporative air cooler. In particular it provides an improved air cooler with improved air discharge system that facilitates multi directional discharge of air as per user/ site requirement.

BACKGROUND OF INVENTION

Evaporative air cooler has been studied and developed for a long. It is an efficient and sustainable method for cooling. Evaporative air cooler function best in the more climates conditions, cooling by evaporating water into a stream of air and delivering the cooled air to the space to be cooled. A conventional evaporative air cooler includes an internal fan or blower, pillar, top panel, tank and side panel generally of the squirrel cage type, with a sheet metal or plastic fan/ blower shroud connected by appropriate structure usually to a tank or side panel and communicating with a cooled air outlet. Due to previous type of arrangement of conventional apparatus; they have less structural rigidity.

The conventional evaporative air coolers often require air outlet to be on top or bottom or side of an air cooler intend of front of an air cooler depending upon use area and application. Thus; the consumers have to pre-select a model as per their requirement. After having selected a model, there is no flexibility to change the style of use for a different direction of air outlet. The conventional evaporative air cooler have a side panels generally have opening for discharge air; from the outside into the blower or fan with some form of water wicking or spray apparatus. The conventional apparatus of evaporative air cooler have generally requirement of different parts of assembly for making side discharge, bottom discharge type air coolers. Therefore; the inconvenience to make different assembly for different discharge types of air cooler system.

In conventional apparatus of evaporative air cooler the air outlet is always fixed at the front or side or back or top or bottom. Thus; the conventional apparatus do not have a flexibility to choose air outlet side of the cooler and they enable to easily assembled and interchangeable .

PRIOR ART

Korean Patent Application KR200312142 relates to room air conditioners front panel and the top panel gaepae structure, in more detail is provided with a front panel and a top panel, a suction port in the indoor unit provided with air conditioning, a hinge on one side to open and close the front panel by the top cover and, with the said top cover and a front cover connected to a hinge on one side to gaepae the front panel with a drive member for the upper cover and front cover provides rotational power to the opening and closing operation, the drive member and the first rack gear and the second rack gear in which each slide, the first rack gear and the upper cover one end and the other end is hinged connected to the first rotation arm and the first rotation of the same structure as the arm and the second rack gear and it consists of a second rotary arm connected to each of the hinge to the front cover.

However it includes two sides opening for air discharge which is front panel and top panel in air cooling system and so, it fails to teach the universal/ multi air discharge system. The components included in the invention are neither interchangeable nor detachable. Therefore, it fails to provide universality of the air discharge system.

Another US Patent Application US3680328A relates to an improved air-conditioner which is basically, the air- conditioner comprises casing means mountable within an opening into a room, air-conditioning means contained within the casing, and blower means contained within the casing for drawing air from the room into the casing and proximate to the air conditioning means for conditioning thereby and then discharging the conditioned air to the room. However, in particular accordance with the present invention, the blower means that is contained within the air-conditioner has an impeller rotatable journal led between two spaced apart blower housing walls and is provided with scroll means that can perform a dual function of bridging the two housing walls and also providing a plurality of air discharge ports from the blower housing.

However, said prior art relates to improved air-conditioner or self- contained air-conditioner units which includes casing on the top, bottom, front and side walls but fails to provide universal/ multi panel construction. The self-contained air-conditioner units are frequently employed to condition the air within a single residential room or confined space and are widely referred to as "room air conditioners” thus; it fails to provide universal air discharge system and also does not provide flexibility, detachability and interchangeability.

Disadvantage of Prior Art:

The above-mentioned prior art suffers from all or at least one of the following disadvantages:

• Most of them provide an air outlet to be on top or bottom or side of an air cooler intend of front of an air cooler depending upon use of area and application and thereby fail to provide air cooler that discharges air in all three directions.

• Most of them fail to provide a flexible air cooler that discharges air in all three directions.

• Most of them lack multi panel construction.

• They fail to provide panels that can be easily interchanged and be assembled.

• Most of them do not have the flexibility to change the direction of panels as per need of the user or site and hence are not user friendly.

• Most of them have less structural rigidity due to their arrangements of existing components.

• Many of them fail to provide multiple assemblies for multi directional air discharge; and therefore are not efficient.

• Most of them have number of additional parts which leads to increases the cost of the model.

Thus, there is an unmet need to develop an invention that obviates the problems associated with prior art OBJECTS OF THE INVENTION
