Description: • 0 BACKGROUND OF THE INVENTION DISPENSER HOUSING 1. Field of the Invention The present invention relates to housings, and more particularly but not by way of limitation, to a housing for use with a dispenser. 5 2. Description of the Related Art A housing surrounds and improves the aesthetics of a soda and/or ice dispenser. Typically, the housing has pivotal panels and removable plates so that a repairman services the dispenser by lifting and bracing the panels or 10 unscrewing the plates. The use of these conventional dispenser housings suffers several disadvantages. Conventional housings, using parts such as screws or bolts, complicate the opening of the housing and training of repairmen. Opening 15 conventional dispenser housings wastes time in locating suitable tools. Additionally, conventional dispenser housings, having detachable parts, require extra training of repairmen that potentially is unavailable in remote areas. 20 Another disadvantage with conventional housings is that detachable parts, such as screws and bolts, must be accounted for during servicing. These parts if missing must be replaced, otherwise the dispenser housing's stability may be jeopardized. 25 Yet another disadvantage of conventional housings is that the panel covering the dispenser valves does not pivot downward. The panel, failing to pivot downward, hinders accessibility of the valves during servicing. An additional disadvantage of conventional housings is that the removable plates and pivotal panels are sometimes difficult to reach, causing a repairman to climb to the top of the housing to remove plates or open panels for accessing the dispenser. A further disadvantage of some conventional housings is that the water and syrup adjusters are inaccessible unless a plate is detached by removing screws or bolts. Accordingly, a housing having unfolding facial members will improve serviceability over conventional housings. SUMMARY OF THE INVENTION In accordance with the aims of the present invention, one embodiment of a dispenser housing includes a face . The face has a valve casing pivotally extendable to provide access to the valves of a soda dispenser. Another embodiment of the present invention is a jointed connection for a valve casing of a soda dispenser housing. The jointed connection includes at least one valve casing joint having a plate, a lever, and a pin. The plate has a plurality of legs extending therefrom wherein each of the legs has an aperture therethrough. The lever is insertable through the apertures. The pin is releasably engageable with the lever to permit longitudinal and pivotal movement of the valve casing. An additional embodiment of the present invention is a dispenser unit. The dispenser unit includes a soda dispenser and a housing. The soda dispenser has at least one valve and one switch. The housing has a face which, in turn, includes a first access member pivotally movable between a first position and a second position to provide access to the soda dispenser, and a valve casing being longitudinally and pivotally extendable to provide access to the valve of the soda dispenser. The valve casing has an aperture access member and covering. The aperture access member and covering each have at least one aperture. The aperture access member is positionable to align the aperture of the aperture access member with the aperture of the covering. It is, therefore, an object of the present invention to provide a housing that protects a dispenser. Another object of the present invention is to provide an easily opened housing without utilizing removable fastening members. A further object of the present invention is to provide an invention having casing members that are connected without the use of fastening members . Another object of the present invention is to provide a housing having access openings to the dispenser valves for adjusting the water and syrup flow rates. An additional object of the present invention is to provide an aperture access cover for permitting opening and closing of the valve adjustment apertures. A further object of the present invention is to provide a valve casing that is longitudinally extendable and downwardly pivotal for accessing the dispenser valves.
