Mode control arrangement for a floor
First Claim
1. A floor care appliance, comprising:
- a suction nozzle for performing a cleaning operation on a floor surface;
a foot pedal for raising and lowering the suction nozzle in relation to the floor surface;
a rotary agitator;
a drive motor for powering the rotary agitator; and
a switch connected in circuit with the drive motor, the switch having a first position at which the motor is energized and having a second position at which the motor is de-energized, as the suction nozzle is moved in relation to the floor surface; and
an actuator in operative contact with said foot pedal and said switch.

Abstract
The invention is a bare floor cleaning appliance provided with a foot pedal for raising and lowering the suction nozzle while simultaneously energizing and de-energizing the independent drive motor powering a horizontal axis rotary agitator. The foot pedal is depressed once to lower the suction nozzle to a position closest to the floor surface and the horizontal rotary agitator is energized to clean the floor surface. Suction from the motor-fan assembly is used to pick up dirt and used cleaning solution. The foot pedal is depressed one more time to raise the suction nozzle from the floor surface and de-energize the horizontal rotary agitator. In this mode, suction from the motor-fan assembly is used to pick up dry objects including dirt. The foot pedal operates the switch for energizing and de-energizing the independent electric motor by rotating a mode indicator operably connected to the foot pedal. Depressing the foot pedal once rotates the mode indicator to a first position which toggles the switch from the off position to the on position. When rotated into this position, an first indicating portion on the mode indicator is rotated underneath a first viewing window formed in the hood of the cleaner foot. Depressing the foot pedal another time rotates the mode indicator to a second position which toggles the switch from the on position to the off position. A second indicating portion on the mode indicator rotates underneath a second viewing window formed in the hood of the foot. At the same time the first indicating portion is rotated out of sight of the first viewing window.

6. A floor care appliance, comprising:
-
a suction nozzle attached to a base; a hood fitted over the base; a pair of apertures formed in the hood; a foot pedal for raising and lowering the suction nozzle; a rotary agitator; a drive motor for powering the rotary agitator; and a switch connected in circuit with the drive motor, the switch having a first position at which the motor is energized and having a second position at which the motor is de-energized, as the suction nozzle is moved between a first position and a second position; a mode indicator in operative contact with the foot pedal and the switch for toggling the switch from the first position to the second position as the suction nozzle is raised and lowered; wherein said mode indicator further includes a first arm which urges said foot pedal when said foot pedal is depressed, thereby rotating said mode indicator; and wherein said mode indicator includes a second arm which urges against said switch when said mode indicator is rotated to toggle said switch between said first and second positions; two visual indicia located on the mode indicator with one visual indicia associated with the first position of the switch and the first position of the suction nozzle and the other visual indicia being associated with the second position of the switch and the second position of the suction nozzle wherein the visual indicia are moved into a position where the indicia can be seen through an associated aperture in said hood to indicate the status of said drive motor and said suction nozzle.
