Abstract

A soap dispenser includes a soap supply, a motor driven pump connected by tubing to the soap supply and a soap output device connected by tubing to the motor driven pump. The electric drive circuit for operating the pump motor includes a sensor for detecting a user's hands positioned to receive soap from the output device. There is a forward motor control circuit connected to the sensor and to the pump motor and responsive to a start signal from the sensor to drive the pump motor in a forward direction to supply soap to the output device. There is a volume adjust circuit connected to the forward motor control circuit and to the sensor to provide a stop signal to the forward motor control circuit a predetermined time period after receipt of a start signal from the sensor. There is a reverse motor control circuit connected to the pump motor and to the volume adjust circuit and responsive to a stop signal from the volume adjust circuit to drive the pump motor in a reverse direction to reverse the flow of soap to the output device.
