Abstract: The device for diffusing sprayed liquid in a reception zone includes a vessel suitable for containing a liquid for spraying and at least one diffuser of sprayed liquid that is arranged in the vessel. The diffuser includes in particular an ultrasound emitter. The cleaning method is such that during a stage of operation of the device in which the device is not diffusing liquid in the reception zone, the following steps are performed: heating a liquid in the vessel up to a predetermined temperature, preferably higher than 60° C., in particular lying in the range 65° C. to 80° C.; and draining the liquid from the vessel via a pipe of the device that is situated outside a circuit for diffusing sprayed liquid in the reception zone.

Abstract: A method of atomizing is implemented using a liquid atomizer device having an open-topped vessel suitable for containing a liquid for atomizing, and an atomized liquid diffuser arranged in the vessel. The diffuser comprises both a nozzle containing the liquid coming from the vessel and an ultrasound emitter suitable for emitting ultrasound waves into the liquid so as to atomize it. The method includes a stage of atomizing the liquid, which stage is performed until the level of liquid in the vessel is substantially at a predetermined minimum level. The method further comprises a stage of temporarily interrupting the ultrasound emitter during an interruption duration, which stage is performed at the end of the atomizing stage, and during which the liquid contained in the nozzle drops back into the vessel; and then a new atomizing stage that is performed at the end of the interruption duration so long as the level of liquid in the vessel is above the predetermined minimum level.
