Abstract

L'invention concerne un procédé et un dispositif permettant de faire fonctionner un système de dosage à l'intérieur d'un appareil ménager à circulation d'eau, en particulier d'un lave-vaisselle, comprenant un appareil ménager à circulation d'eau muni d'au moins un émetteur côté appareil ménager (Sh) et d'au moins un récepteur côté appareil ménager (Eh), ainsi qu'un appareil de dosage pouvant être positionné à l'intérieur de l'appareil ménager à circulation d'eau, ledit appareil de dosage étant muni d'au moins un émetteur côté appareil de dosage (Sd) et d'au moins un récepteur côté appareil de dosage (Ed). Selon l'invention, au moins un récepteur côté appareil de dosage (Ed) est connecté en discontinu de manière à ne pouvoir recevoir aucun signal d'un émetteur correspondant côté appareil ménager (Sh) au cours d'un premier intervalle (ΔT1,d,e) et à pouvoir recevoir des signaux d'un émetteur correspondant côté appareil ménager (Sh) au cours d'un second intervalle (ΔT2,d,e), le premier intervalle (ΔT1,d,e) étant ≥ au second intervalle (ΔT2,d,e) et au moins un émetteur côté appareil ménager (Sh) étant conçu pour émettre un signal qui peut être reçu par un récepteur correspondant côté appareil de dosage (Ed), le signal présentant une durée (ΔT1,h,s) qui est supérieure au premier intervalle (ΔT1,d,e) au cours duquel le récepteur correspondant côté appareil de dosage (Ed) ne peut recevoir aucun signal de l'émetteur correspondant côté appareil ménager (Sh).
