“AN AIR DEFLECTOR SYSTEM FOR AN AIR COOLER”
We, Bajaj Electricals Limited, an Indian National, of 45/47, Veer Nariman Road, Fort Mumbai- 400001, India.
The following specification particularly describes the invention and the manner in which it is to be performed.

TECHNICAL FIELD
The present invention relates to an air cooler, more particularly, to an air deflector system of the air cooler.
BACKGROUND
This section is intended to provide information relating to the field of the invention and thus, any approach or functionality described below should not be assumed to be qualified as prior art merely by its inclusion in this section.
Air coolers are commonly known in the Heating, Ventilation, and Air Cooling (HVAC) industry, and are widely used in households. The air cooler is employed for delivery of cool air in a desired space or room.
Typically, the air cooler comprises a housing/body defining a front air outlet opening, and a fan arrangement disposed within the housing/body and adapted to generate an airflow through the front air outlet opening defined within the body thereof. The air cooler further employs a frame fixedly attached to the front air outlet opening in the housing/body, and an air deflector system generally pivotally attached to the frame thereof, such that the air deflector system is capable of varying a direction of the airflow generated by the fan arrangement, when desired. A structure and arrangement of the air cooler is commonly known to a person skilled in the art, and the details of the same are not repeated herein for the sake of brevity. Additional supporting accessory

arrangements may also be envisioned.
Conventionally, the air deflector system includes a set of vertical louvers and/or a set of horizontal louvers, which are used to vary the airflow generated by the fan arrangement, in a vertical direction and/or a horizontal direction respectively. In such a conventional air deflector system, the set of vertical and/or the set of horizontal louvers, obstruct the airflow generated by the fan arrangement. Particularly, the airflow from the fan arrangement is a swirling divergent flow, while the louvers are positioned perpendicular, obstructing the airflow. This generates vortices in the airflow, and thus, gives rise to pressure loss and generation of air cutting noise, which further translates into a decrease in peak air velocity (PAV) and increase in power consumption.
Therefore, there is a well felt need to provide an air deflector system for the air cooler, capable of providing an increased peak air velocity (PAV), reducing air-cutting noise and power consumption thereof, while increasing the air throw distance.

The at least one louver unit [401A, 401B] can be further adjusted in a third adjustment state such the first louver unit [401A] pivots downwards and the second louver unit [401B] pivots upwards. Notably, in the third adjustment state, the airflow through the first louver unit [401A] is directed towards the floor of the room and the airflow through the second louver unit [401B] is directed towards a ceiling of the room.
The at least one louver unit [401A, 401B] can be further adjusted in a fourth adjustment state such the first louver unit [401A] and the second louver unit [401B] both pivot

downwards, deflecting the airflow, such that the delivery of the airflow is towards the floor of the room. Notably, in the fourth adjustment state, the airflow through both the first louver unit [401A] and the second louver unit [401B] is directed towards the floor of the room.
The at least one louver unit [401A, 401B] can be further adjusted in a fifth adjustment state such the first louver unit [401A] pivots upwards and the second louver unit [401B] pivots downwards. Notably, in the fifth adjustment state, the airflow through the first louver unit [401A] is directed towards the ceiling of the room and the airflow through the second louver unit [401B] is directed towards the floor of the room.
With such an arrangement, the air deflector system [102] for the air cooler [100], as disclosed in the present invention, proves to be capable of providing an increased peak air velocity (PAV), reducing air-cutting noise and power consumption thereof, while increasing the air throw distance. The specific semi-circular shape of the at least one louver unit [401A, 401B] furthers the above mentioned advantages in the field of the art.
While the preferred embodiments of the present invention have been described hereinabove, it should be understood that various changes, adaptations, and modifications may be made therein without departing from the spirit of the invention and the scope of the appended claims.
