## Background
I. FIELD OF THE INVENTION
The present invention generally relates to air filtering assemblies, and, more particularly, to an air filtering assembly capable of preventing entry of particulate matter such as dust, mold, and the like, into a compressor compartment of a refrigeration apparatus.
II. MOTIVATION FOR THE INVENTION
Typically a refrigeration apparatus, such as a refrigerator, a freezer, and the like, includes a cabinet having a storage compartment and a door for accessing the storage compartment. The refrigeration apparatus is a free-standing structure and is usually placed on a flat surface such as a floor and the like. The cabinet of the refrigeration apparatus further includes a compressor compartment configured below the storage compartment for housing machine components such as a compressor unit, condenser coils, and the like. Further, the compressor compartment includes an air-vent portion capable of providing a passageway for hot air released by the machine components.
However, the air-vent portion of the compressor compartment may also provide an easy passageway for the entry of air with particulate matter such as dust, mold, bacteria, and the like. Further, the particulate matter become get accumulated on the machine components of the compressor compartment, and such an accumulation may impair the proper functioning of the machine components. Removal of the particulate matter from the machine components is a tedious job that involves cleaning of the refrigeration apparatus.
A conventional method of cleaning refrigeration apparatus for removing the particulate matter from the machine components involves use of cleaning tools such as a cleaning brush, a duster, and the like. Such cleaning tools may enable a user to remove the particulate matter in order to provide a clean environment in the compressor compartment for enhancing efficiency of the machine components. However, use of such conventional method for removing the particulate matter accumulated on the machine components is inconvenient and cumbersome, as the user needs to lie down on a surface supporting the refrigeration apparatus to reach the compressor compartment. Further, the cleaning tools are incapable of cleaning inaccessible areas in the compressor compartment for the removal of the particulate matter. Very often, the user may have to use his/her hand to reach the inaccessible areas in the compressor component to remove the particulate matter from the machine components. However, while cleaning, the hand of the user may get injured by metallic frames that may be located in the compressor compartment.
Further, during cold weather conditions, the particulate matter may accumulate to form a thick layer on the condenser coils present of the compressor compartment. Heat exchange by the condenser coils harden the thick layer of the particulate matter, which is difficult to remove from the condenser coils. Moreover, such condenser coils having the thick layer of particulate matter thereon may consume more power for exchanging heat; accordingly, use of the condenser coils with the thick layer of particulate matter thereon may prove cost-ineffective.
Furthermore, the compressor compartment may retain moisture therewithin from water that leaks from the storage compartment of the refrigeration apparatus, during improper working conditions of a cooling mechanism, and the like, of the refrigeration apparatus. Dampening of the compressor compartment from the leakage of the water from the storage compartment may impair the functioning of the machine components of the compressor compartment, which in turn reduces the lifespan of the refrigeration apparatus.
Attempts have been made to provide a protecting cover, such as a built-in window, for covering a compressor compartment of a refrigeration apparatus. Such built-in window is detachably attached to an air-vent portion of the compressor compartment of the refrigeration apparatus for providing a passageway for hot air released from the compressor compartment. However, the built-in window permits the flow of the hot air from the refrigeration apparatus, and as such is incapable of preventing entry of the particulate matter that may be present in the air into the compressor compartment.
Accordingly, there persists a need for precluding entrance of particulate matter present in the air into a compressor compartment of a refrigeration apparatus, in order to prevent accumulation of the particulate matter in the compressor compartment. Further, there exists a need for keeping a compressor compartment of a refrigeration apparatus free from moisture.
Therefore, it is an object of the present invention to obviate the above and other disadvantages from existing art and to provide an air filtering assembly that is capable of preventing particulate matter such as dust, mold and the like, from entering into a compressor compartment of a refrigeration apparatus.
It is further an object of the present invention to provide an air filtering assembly capable of keeping a compressor compartment of a refrigeration apparatus free from moisture.
It is still an object of the present invention to provide an air filtering device, which is, safe, user-friendly, and cost effective.
