FIELD OF INVENTION

This invention relates to vehicle under mounted container, more particularly, to vehicle under mounted container for holding a variety of heating ventilation and air conditioning (HVAC) apparatuses.

BACKGROUND

Heaters, air-conditioners and other air conditioning appliances are installed in vehicles to improve passenger comfort. These appliances are typically mounted inside the vehicle or on the roof of the vehicle. Appliances located within the vehicle occupy limited interior space and increase noise within the interior space, which can cause irritation to the driver and passengers. Some vehicles overcome these draw backs by mounting the appliances on the roof. The drawback for mounting appliances on the roof: increases the overall height of the vehicle and in turn increases potential damage to the roof from overhead structures; and, raises the center of gravity of the vehicle, which decreases vehicle stability around turns and windy roads.

Some recreational vehicles (RVs) have RV specific furnaces that are directly mounted under the vehicle floor. However, these furnaces are more expensive then typical appliances, limited in mounting options, limited in heating capacity, limited in availability, and are not approved by the United States RV manufactures. There is a need for a container to capable of being mounted under a vehicle floor that is able to hold a variety of HVAC appliances.

BRIEF SUMMARY OF THE INVENTION

A container for mounting under a vehicle floor, the container comprising: a plurality of side walls, wherein the plurality of side walls have a plurality of openings; a top wall is attached to a top portion of the plurality of side walls, wherein the top wall is attached to the vehicle floor; a removable floor is attached to a bottom portion of the plurality of side walls; a cavity defined by the plurality of side walls, the top wall, and the floor, wherein the cavity contains an HVAC apparatus. The container further comprising: a plurality of ducts comprising a plurality of first ends connected to the plurality of openings in the plurality of side walls; and, a plurality of second ends connected to a plurality of outputs; wherein air from the HVAC apparatus flows through the plurality of ducts from the plurality of openings to the plurality of outputs; a plurality of pipes, wherein the plurality of pipes comprise of at least one of a water pipe and a gas pipe; at least one electrical connector; and at least one control connector.
