Refrigeration unit for vending machines

DETAILED DESCRIPTION OF THE INVENTION In FIG.
1 of the drawings, I have illustrated a coin-operated vending machine V of that general type and/or class of machine here concerned with and have shown my new refrigeration unit U related to it.
The machine V that I have elected to illustrate is of no particular make or model and is only intended to show the basic parts and/or portions of a typical machine structure with which my new unit can be advantageously related.
The machine V is characterized by an exterior, rectilinear box-like cabinet 10 with a flat, horizontal top panel 11 and vertical front and side panels 12 and 13.
In addition to the foregoing, the cabinet has a rear and a bottom panel (not shown).
In accordance with common practice, the cabinet establishes a closed and substantially sealed interior space in which the coin and product-handling mechanisms (not shown) of the machine are contained.
The front panel 12 is shown as having a window opening 14 in which items to be dispensed are displayed; coin-receiving and return slots or openings 15 and 16; manually engagable product selecting and actuating knobs 17; and, a product delivery slot 18.
The most common standard feature of the great majority of existing vending machines of the type and/or class here concerned with is the basic rectilinear box-like form of the machine cabinets.
While machines constructed to handle and vend different numbers of items may vary substantially in width, the difference in height and depth of the great majority of different makes and models of vending machines varies only slightly.
The foregoing is understood to be the result of building codes and standards that have, to a great extent, dictated and limited that space that is provided in most building structures and the like to accommodate vending machines.
It is to be noted that the front panels of most vending machines of the class here concerned with are hinged closures in the nature of doors that can be pivoted open to provide access to the interiors of the machines in the normal course of servicing and maintaining them
