System of a household appliance and an accumulator having an optical display means

Abstract

A system of a household appliance has an appliance housing, an accumulator having an accumulator housing and an integrated optical display, and a display control for controlling a display of information on the accumulator display. The appliance has a detector for determining appliance states of the appliance, which do not relate to the accumulator, wherein the detector is configured to transmit the detected appliance state to the display control, wherein the display control is configured to control the accumulator display to display the received appliance state. The display control is configured to control the display of a remaining running time, which specifies how long a charging capacity, which is still available in the accumulator, will last, to complete an activity, which is currently performed, wherein the remaining running time relates to a combination of an appliance parameter of the appliance and of the current charging capacity of the accumulator.

What is claimed is: 
     
         1 . A system of a household appliance ( 1 ) having an appliance housing ( 6 ), an accumulator ( 2 ) having an accumulator housing ( 5 ) and an optical display means ( 3 ) integrated therein, and a display control means ( 4 ) for controlling a display of information on the display means ( 3 ) of the accumulator ( 2 ), wherein the household appliance ( 1 ) has a detection means ( 7 ) for determining appliance states of the household appliance ( 1 ), which do not relate to the accumulator ( 2 ), wherein the detection means ( 7 ) is set up to transmit the detected appliance state of the household appliance ( 1 ) to the display control means ( 4 ), wherein the display control means ( 4 ) is set up to control the display means ( 3 ) of the accumulator ( 2 ) to display the received appliance state of the household appliance ( 1 ), wherein the display control means ( 4 ) is set up to control the display of a remaining running time, which specifies how long a charging capacity, which is still available in the accumulator ( 2 ), will last, in order to complete an activity, which is currently performed, wherein the remaining running time relates to a combination of an appliance parameter of the household appliance ( 1 ) and of the current charging capacity of the accumulator ( 2 ). 
     
     
         2 . The system according to  claim 1 , wherein the optical display means ( 3 ) of the accumulator ( 2 ) has a display ( 8 ) and/or at least one light-emitting diode ( 9 ). 
     
     
         3 . The system according to  claim 1 , wherein the display control means ( 4 ) is a component of the accumulator ( 2 ). 
     
     
         4 . The system according to  claim 1 , wherein the accumulator ( 2 ) is accommodated in the appliance housing ( 6 ) of the household appliance ( 1 ), wherein the display means ( 3 ) of the accumulator ( 2 ) can be read through a housing recess ( 10 ) of the appliance housing ( 6 ). 
     
     
         5 . The system according to  claim 1 , wherein the accumulator ( 2 ) is connected to the appliance housing ( 6 ) of the household appliance ( 1 ) in a reversibly separable manner. 
     
     
         6 . The system according to  claim 1 , wherein the display control means ( 4 ) is furthermore set up to also display an accumulator state, in particular a charging state or an aging state of the accumulator ( 2 ), on the display means ( 3 ) of the accumulator ( 2 ). 
     
     
         7 . The system according to  claim 1 , wherein the display means ( 3 ) of the accumulator ( 2 ) is formed to display an appliance state and/or accumulator state as color signal, text and/or image. 
     
     
         8 . The system according to  claim 1 , further comprising two interchangeable accumulators ( 2 ), which, based on the displayable appliance states and/or accumulator states, have display means ( 3 ), which are formed so as to be different from one another. 
     
     
         9 . The system according to  claim 1 , wherein the household appliance ( 1 ) is a floor treating appliance, in particular a cleaning appliance. 
     
     
         10 . The system according to  claim 1 , wherein the appliance parameter is selected from the quantity: cleaning power, suction power, liquid delivery rate, fill level of a container ( 11 ) for a liquid or a solid, temperature of a component, service requirement of an appliance component, appliance error, collision status of the household appliance ( 1 ) with an obstacle, remaining running time until the completion of an activity, activity of a communication interface, relative spatial orientation of a handle ( 12 ) that is movably arranged on the appliance housing ( 6 ) of the household appliance ( 1 ), handling parameters of the household appliance ( 1 ), accessory parameters of an accessory ( 13 ) that is separably connected to the household appliance ( 1 ), in particular of a suction nozzle or of a cleaning element.
