Abstract:
1. A method of controlling a liquid diffusion appliance to treat an enclosed space with a liquid diffused by the appliance, the appliance including a reservoir of the liquid and a diffuser for diffusing the liquid into the enclosed space, the method comprising: providing a plurality of control schemes for the appliance based on characteristics of the liquid and a desired level of treatment for the space, each of the control schemes specifying operational parameters for the appliance including a flow rate of liquid, and a periodic timing of operation of the diffuser, each of the plurality of control schemes based on a rate of decay of the liquid within the enclosed space and the desired level of concentration of the liquid within the enclosed space, so that the periodic timing of operation of the diffuser includes a period when the diffuser is not operating to diffuse the liquid into the enclosed space so as to permit the liquid within the space to decay to a concentration of the liquid below the desired level of concentration of the liquid, and a period when the diffuser is operating to diffuse liquid into the enclosed space to raise the concentration of the liquid from below the desired level of concentration to the desired level of concentration of the liquid; determining a volume of the space to be treated; selecting one of the plurality of control schemes based on the volume of the space to be treated; operating the appliance based on the selected one of the plurality of control schemes.
