Through-the-wall dispensers

Abstract

Exemplary through-the-wall touch-free dispensers are disclosed herein. An exemplary through-the-wall touch-free dispensers system includes an elongated wall mounting base. The elongated wall mounting base has a length and a width, the length is greater than the width and the wall mounting base is configured such that the length is in the vertical direction when the touch-free dispenser is mounted on a wall. Also included is a spout and a base housing. The spout extends further outward from the wall than the base housing and the base housing extends below the spout. An object sensor is located in the base housing below the spout. A liquid inlet conduit that is configured to extend through at least a portion of the wall is also included. A pump is in fluid communication with the liquid inlet. A reservoir for holding liquid is in fluid communication with the pump. In addition, the dispenser includes control circuitry for causing the touch-free dispenser to dispense fluid.
