ABSTRACT:

TECHNICAL FIELD
This invention relates to control boxes for electrical appliances and more specifically, to the mounting of a control box within such an appliance.
BACKGROUND ART
Most electrical appliances are provided with self-contained electrical control boxes. Such control boxes typically include control switches such as on/off switches, function switches, thermostats, etc. Power cords for such appliances usually pass into the, control box where appropriate electrical connections are made to the various control components and electrical wiring distributing control signals and power to various power utilizing components of the appliance pass from the control box. Control boxes are known, which are made from sheet metal components as well as molded plastic components. Regardless of the type of structure, a control box must be supported and adequately attached to appropriate structural components of the appliance in which it is used Such support and attaching hardware quite often is overly complex and adds cost for both materials and labor to the appliance. It is accordingly deemed desirable to have an electrical control box which is easily installed and removed from an electrical appliance.
DISCLOSURE OF THE INVENTION
An electric appliance in a control box mounted within the appliance. The appliance has a planar support wall, which includes first and second mounting rails carried by the support wall. Each of the mounting rails includes an L-shaped structure having a first leg attached to the wall and a second leg supported by the first leg in spaced parallel relationship with the wall. The free edges of the first and second mounting rails are configured to face one another in parallel spaced relationship with one another. The control box is provided with a planar mounting wall, which has a first rail engaging structure formed thereon which is configured to be slidingly received in the space between the second leg of the first mounting rail and the planar support wall. The planar mounting wall includes a second rail engaging structure, which is configured to be slidingly received in the space between the second tee of the second mounting rail and the support wall.
