Field of the invention
The present field of invention relates to an evaporative air cooler that is capable of being disintegrated and assembled as and when required. More particularly, the present invention relates to a collapsible evaporative air cooler comprising of an upper body that may be collapsed into the lower body of said cooler.
Background of the invention
An evaporative air cooler primarily comprises of a motor driven blower or a fan for air circulation, along with a water tank to hold required water and cooling media through which the water is circulated by way of a pump to cool the circulating air. Apart from this, there is a front grill which comprises of louvers to regulate the direction of the air for convenience of the user. The tank sits over a main body and the overall size of the product remains unchanged.
The air coolers are seasonal products and hence are not used throughout the year. Rather air coolers are used for a very short span of time in a year and are stored unused for the rest of the year. The conventional air coolers, as available in the market, are very large and bulky and hence require a large amount of storage space, when not in use or when said coolers are required to be transported from one place to another.
An air cooling system has been disclosed in US 8448813 B2. Said invention relates to an expandable and collapsible cooler includes: a base defining a bottom portion of the cooler; an upper rim defining an upper portion of the cooler; and a collapsible cooler wall extending between and attached to the base and the upper rim and surrounding an interior storage space of the cooler. The cooler wall includes a flexible elastomeric membrane that includes a plurality of hinge lines at which the membrane is configured to bend such that the

membrane is transitional between a collapsed configuration and an expanded configuration. The cooler is transitional between an expanded configuration and a collapsed configuration by bending of the membrane along the hinge lines. Each configuration is a stable configuration of the cooler. The collapsible cooler wall includes peripheral portions thereof that nest within each other when the collapsible cooler wall is fully collapsed. The collapsible cooler wall tapers in extending from the upper rim.
Another air cooling system has been disclosed in US 7815069 B1. Said invention relates to a collapsible, soft-sided, insulated cooler or other container having a top, a sidewall having a sidewall top connected to the rim of the top and a bottom connected at a sidewall bottom, opposite the top. The top includes a zipper or other closure that extends from a first point to a second point on the rim of the top in a line along a radial segment, traversing a central region of the top. The sidewall comprises an inner layer, an outer shell and an insulating material disposed there between. The sidewall further includes a spring wire that extends between the bottom and top of the container that biases the cooler to a fully expanded configuration for use and that is compressible for storage by pressing down on the top.
Yet another air cooling system and method has been disclosed in US 3921902 A. Said invention relates to a water cooling system wherein collapsible cooling towers are supported above the body of water to be cooled. The cooling towers are composed of collapsible side walls which extend under the influence of the pressurized water being supplied thereto. A plurality of baffles are provided about the upper end of the extended towers and the water supplied to the towers flows over the baffles which divides the water into droplets thereby cooling the water.

The air cooling systems as described in the prior art are quite expensive and handling said coolers is a very tedious task.
Objective of the Invention
The objective of the present invention is to design an evaporative air cooler that is easy to transport, convenient to use and does not require a huge amount of storage space while not in use.
Yet another objective of the instant invention is to employ a concept on an evaporative air cooler whereby the overall height of the evaporative air cooler is reduced.
The instant invention achieves the objective by designing an evaporative air cooler that is capable of collapsing whereby the upper body of the said cooler slips into the lower body of the cooler. The procedure of collapsing the cooler does not require any extra hardware and the cooler may be collapsed by way of integral mechanism employed in the evaporative air cooler.
Summary of the Invention
The present invention relates to a collapsible evaporative air cooler, said cooler comprising of: a control panel; air circulation component; a front grill; a back grill; side grills; a louver assembly; a cooling media; a water level indicator; a water tank; electrical parts and a hatched area.
According to the invention, the front grill of the cooler holds said louver assembly and delivers cool air. The louver assembly comprises of a horizontal louver and a vertical louver and the movement of the louver assembly may be operated manually or through a motor. A water tank holds the water that is circulated over the cooling media providing cooling effect, wherein the capacity

of the water tank ranges from 40 Litres to 120 Litres. The side grill of the cooler sucks the air and holds the cooling media. Also, the control panel installed in the collapsible cooler may be operated electronically or manually.
According to a preferred embodiment of the invention, the cooling media comprises of a honeycomb or a wood wool.
According to another preferred embodiment of the invention, the hatched area houses the engineering assembly that facilitate the collapsing of the body through push or pull by the user.
According to a preferred embodiment of the invention, the air circulation component may comprise of a fan or a blower. Further, said cooler is employed with four or eight locking latches, wherein further two or Four latches are installed in the front side and remaining two or Four latches are provided in the back side of said cooler.
according to another preferred embodiment of the invention, said cooler is provided with four or eight connecting links are provided in said cooler, wherein further two or four connecting links are for front and top side and the remaining two or four connecting links for the back and top of said cooler.
The present invention also relates to a method of collapsing the evaporative air cooler, said method comprising the steps of: folding front left and front right side grills on the outside of said cooler towards back grill at an angle of 180 degrees; folding back left and back right side grills towards the inside of said cooler thereby making said grills rest on the back grill; opening 2 or 4 front lock latches and 2 or 4 back lock latches; lifting of top panel upwards by employing lifting handle thereby making the front and the back assembly swing towards inside of said cooler by virtue of connecting links; inserting the upper assembly into the water tank until the top panel rest on side edges of water tank; and

losing 2 or 4 front latches and 2 or 4 back latches while the top panel rests on the edge of the water tank.
The present invention relates to a method of re-assembly of the collapsed evaporative air cooler, said method comprising the steps of: unlocking 2 or 4 front latches and 2 or 4 back latches; lifting the handle present on the top panel to pull the assembly out of the water tank; fixing the front panel and back grill in the pocket present in the tank; fixing the top on front panel and back grill; locking 2 or 4 front latches and 2 or 4 back latches; unfolding back left and the back right side grills in anti-clockwise direction; unfolding front left and front right side grills in the clockwise direction towards the front panel at an angle of 180 degrees.
Brief Description of the invention The present invention relates to an evaporative air cooler that is capable of being disintegrated in order to reduce the overall height of the cooler thereby leading to decrease the storage space required by said cooler, when not in use. The instant invention involves a concept whereby the evaporative air cooler can be collapsed in such a manner that the upper body of the cooler is slid into the lower body of the cooler. Said mechanism employs all the parts of an existing evaporative air cooler along with some additional parts that facilitates the upper body of the cooler getting collapsed within the water tank. The primary function of the upper body is to provide the cool air whereas the tank stores the water which is used to give the cooling effect. Since the tank doesn’t has any water while not in use, the space inside the tank remains

unutilized and can be used to hold the upper body assembly and reduce the overall product size (height) for convenient storage. Brief Description of the drawings
