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.
