Abstract
Abstract The present invention relates to a circuit for memorising in digital form in an electronic memory data relative to an operating programme of a household appliance, in particular, a washing machine, comprising a processing unit which provides for memorising the said data a number of times in the memory during the operating programme and calling it up whenever power is restored to the said processing unit after a manual or accidental power cut; besides the said data, control data is also memorised to enable the processing unit to check whether the called up data is correct; if power is cut off manually, the content of the memory is cleared whereas it is preserved if power is cut off accidentally; when power is restored, the processing unit provides for continuing the interrupted programme if the called up data is found to be correct and for switching the appliance backto its initial condition if it is found to be incorrect.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
225 words
- Circuit for memorising in digital form in an electronic memory data relative to an operating programme of a household appliance, in particular, a washing machine, comprising an on/off switch for turning the appliance on and off, a power supply unit, connected to the household electricity mains via the said switch and supplying, among other things, a processing unit which receives input signals and supplies output signals, and an electronic memory, connected to the said control unit, capable of preserving data in digital form even in the event of a power cut on the said household electricy mains so that, in the event of a mains power cut during a selected operating programme, when power is restored, the appliance is able to continue the said programme more or less from where it was left off whereas, if the appliance is switched off manually during the programme by means of the said switch and then turned on again, the appliance does not take up the programme from where it was left off but starts again from the beginning, characterised by the fact that means are provided for reading the data contained in the said electronic memory when the appliance is started up again and for determining, on the basis of the said data, whether the programme is to be continued or started again from the beginning.
Claim 2
Dependent Claim
225 words
- Circuit for memorising in digital form in an electronic memory data relative to an operating programme of a household appliance, in particular, a washing machine, comprising an on/off switch for turning the appliance on and off, a power supply unit, connected to the household electricity mains via the said switch and supplying, among other things, a processing unit which receives input signals and supplies output signals, and an electronic memory, connected to the said control unit, capable of preserving data in digital form even in the event of a power cut on the said household electricy mains so that, in the event of a mains power cut during a selected operating programme, when power is restored, the appliance is able to continue the said programme more or less from where it was left off whereas, if the appliance is switched off manually during the programme by means of the said switch and then turned on again, the appliance does not take up the programme from where it was left off but starts again from the beginning, characterised by the fact that means are provided for reading the data contained in the said electronic memory when the appliance is started up again and for determining, on the basis of the said data, whether the programme is to be continued or started again from the beginning.
Claim 3
Dependent Claim
74 words
- Circuit according to Claim 1, characterised by the fact that the said processing unit provides a number of times during the programme for memorising in the said memory data relative to the type of programme selected, progress of the same and also control data and for calling up data from the memory and checking if it is correct by means of the said control data whenever the supply unit is supplied with energy.
Claim 4
Dependent Claim
23 words
- Circuit according to Claim 2, characterised by the fact that the control data consists of complements of a preset information data number.
Claim 5
Dependent Claim
202 words
- Circuit for memorising in digital form in an electronic memory data relative to an operating programme of a household appliance, in particular, a washing machine, comprising an on/off switch for turning the appliance on and off, a power supply unit, connected to the household electricity mains via the said switch and supplying, among other things, a processing unit which receives input signals and supplies output signals, and an electronic memory, connected to the said control unit, capable of preserving data in digital form even in the event of a power cut on the said household electricity mains so that, in the event of a mains power cut during a selected operating programme, when power is restored, the appliance is able to continue the said programme more or less from where it was left off whereas, if the appliance is switched off manually during the programme by means of the said switch and then turned on again, the appliance does not take up the programme from where it was left off but starts again from the beginning, characterised by the fact that the content of the said electronic memory it is modified when the appliance is turned off by the said switch.
Claim 6
Dependent Claim
202 words
- Circuit for memorising in digital form in an electronic memory data relative to an operating programme of a household appliance, in particular, a washing machine, comprising an on/off switch for turning the appliance on and off, a power supply unit, connected to the household electricity mains via the said switch and supplying, among other things, a processing unit which receives input signals and supplies output signals, and an electronic memory, connected to the said control unit, capable of preserving data in digital form even in the event of a power cut on the said household electricity mains so that, in the event of a mains power cut during a selected operating programme, when power is restored, the appliance is able to continue the said programme more or less from where it was left off whereas, if the appliance is switched off manually during the programme by means of the said switch and then turned on again, the appliance does not take up the programme from where it was left off but starts again from the beginning, characterised by the fact that the content of the said electronic memory it is modified when the appliance is turned off by the said switch.
Claim 7
Dependent Claim
53 words
- Circuit according to Claim 4, characterised by the fact that the said electronic memory is a volatile type supplied during the mains power cut by an auxiliary battery and that the said on/off switch comprises a section which disconnects the said battery from the said memory when the machine is turned off.
Claim 8
Dependent Claim
11 words
- Memorisation circuit as described and shown on the attached drawing.
Claim 9
Dependent Claim
