Air treatment apparatus and method
First Claim
1. An apparatus for supplying treated air to the interior of an automotive vehicle which includes a forced air circulation system and a temperature control system, said forced air circulation system including an air supply conduit having one of its ends exposed to the atmosphere exterior to the vehicle and the other of its ends terminating in a plurality of vehicle interior ducts and outlets, and a fan and motor operatively associated with said air supply conduit so as to impart forced movement to air within said conduit, said temperature control system including heater core and an evaporator coil each having portions disposed within said conduit, said apparatus further including an air treatment system for discharging a vaporizable liquid into said air supply conduit downstream of said heater core and said evaporator coil, said air treatment system including at least one container for receiving a supply of vaporizable liquid, a liquid pump having a pump inlet, a pump outlet, a pump motor, an atomizing nozzle, and a liquid line extending from said pump outlet to said atomizing nozzle, means for energizing said liquid pump motor and a control circuit for said pump motor energizing means, said control circuit comprising, in combination, a main operating control, means for signaling said operating control that said liquid is to be discharged, separate air flow and temperature sensing means, a pump timer and a logic control unit, said logic control including means for generating an output signal to enable said pump timer to be alternately energized and de-energized, said logic control being operable to energize said pump motor timer only in the conjunctive presence of a positive signal from said main control and from said air flow and temperature sensing means, whereby, when said signaling means is energized, said pump will operate for a controlled time to cause said volatile liquid to be taken from said container and be discharged into said conduit through said atomizing nozzle, provided that said logic control is receiving input signals from said air flow and temperature sensors and said main operating control operating control.

Abstract
An air treatment system for a vehicle or other habitable structure. The apparatus includes a supply of treating fluid, a pump and spray nozzle arrangement, and a control system. The spray nozzle discharges the treating liquid in an atomized condition within an air circulation conduit, and the control system insures that there is air flow taking place in the conduit before atomization begins and that air flow is still continuing after cessation of atomization. The sequences is insured by a logic control and the pump is actuated through a timer and relay arrangement. An automatic conditioned responsive mode of operation can also be provided.
