Definitions
- the invention relates to a household appliance with a display device with which information relating to the remaining life, the device and / or the device status can be displayed spatially separately from the household appliance, this information as data from a preferably electronic program control of the household appliance via a transmitter to a wireless device receiving device arranged in the display device are passed on.
- a household appliance is known from DE-GM 18 95 053.
- Household appliances are known in which there is a detachable signal clock on the control panel which can be set and carried by the user.
- the user has to estimate the program duration and, depending on this, set the clock.
- signal clocks have the disadvantage that neither the program sequence can be checked nor doublet signals can be emitted.
- a display device in which the control unit of a household appliance sends monitoring functions as coded electrical signals to a monitoring receiver via the mains power line. Simultaneous monitoring of different household appliances is to be realized by using several transmission channels and a selection switch in the receiver.
- the disadvantage of the aforementioned display device is on the one hand the dependence on a line system. This considerably limits the viewer's mobility.
- the mains power line is particularly susceptible to interference from superimposed transmissions from neighboring houses, be it from the same devices, baby phone or CB radio. The other is the use of a Selector switch technically complex and can lead to the control of individual devices being forgotten.
- the washing machine known from DE-GM 18 95 053 uses a pulse transmitter and a display device with a pulse receiver in order to control the pointer of a switching mechanism depending on the program status. This means that it is not possible to monitor various household appliances.
- the invention is therefore based on the problem of creating a household appliance with a display device of the type mentioned at the beginning, on which the user receives information about the data of this and other devices safely and easily, regardless of the location of the device
- a microprocessor control is advantageously used, with which the data of several simultaneously operated household appliances can be represented in series or in parallel. In this way, a small, very compact display can be created, which displays the information in a clear manner. Furthermore, there is the possibility of retrofitting existing devices with a transmitter and also using the receiving device for these devices. Another advantage is that all connected household appliances can be checked for unauthorized use via the display device.
- a particularly advantageous development of the invention consists in the fact that the data contain an address code and that an evaluation circuit is integrated in the control device which only permits the display of data of those household appliances which send this address code. In this way, interference from other radio signals is suppressed in the simplest way, in particular an overlay of data which are sent from devices with the same display devices from the neighborhood.
- Particularly advantageous refinements of the invention enable the address code to be changed using the operating elements of the device or in connection with an interface between the electronic program control and the display control.
- the address code can thus also be stored in a non-volatile memory of the display control and can be overwritten from there via the interface into the non-volatile memory of the electronic program control.
- the interface between the electronic program control and the display control is used to exchange process parameters.
- the display device can be used as a storage and transmission medium for updating programs, i. that is, current process parameters of new control generations in devices with older manufacturing dates can be overwritten.
- the display device it is advantageous to equip the display device with an LC display, in which the information relating to the individual devices is shown cyclically in a predetermined order. As a result, the user receives information about all the devices in operation one after the other without any further action.
- the display control has a separate sequence control which, when the connection to the transmitting device is interrupted, automatically updates the display for a predetermined period of time.
- an interface that is freely accessible to the user is arranged on the electronic program control, at which the transmitting device can be contacted with the program control in a holding device.
- the display device can thus be offered as a separate accessory and the transmitter can also be subsequently installed by the user in the device.
- FIG. 1 shows schematically the operation of household appliances designed according to the invention, in the example shown with a stove (1), an automatic dishwasher (2) and an automatic washing machine (3).
- These household appliances all have the following basic structure:
- a control panel (4; 4 '; 4 ") with switching elements (5.5', 5") for selecting a program and / or special functions is arranged in the upper front area of the devices. From there, switching commands are passed on via control lines (6; 6 '; 6 ") to a microprocessor control (7; 7';7"), which they then convert into corresponding programs.
- the microprocessor control (7; 7 '; 7 ") influences time-dependent and condition-dependent various device-specific actuators of the household appliance, usually heaters (8) and motors (9).
- the control variables are partly as fixed process parameters in a ROM (10; 10'; 10 ") and partially stored as changeable process parameters in a first programmable, non-volatile memory, for example an E 2 PROM (11; 11 ';11").
- An address code is stored in a second E 2 PROM (12; 12 '; 12 "), the function of which will be explained later.
- the control panel (4; 4 ', 4 ") Display elements (13; 13 '; 13 "), which represent information to the user which is related to the program selection and the program sequence. These are also controlled in a known manner by the microprocessor control (7; 7 ';7'').
- control lines (14; 14 ';14'') are led from the microprocessor control (7; 7'; 7 ") to a plug (15) in the area of the control panel (4; 4 ';4"). Furthermore, there is a holder (16) in which a transmitter (17; 17 '; 17 ") can be inserted and contacted with the plug (15) (see FIG. 3). The holder is covered by a cover plate (18). closable, so that the plug (15) and the transmitter (17; 17 ';17'') from contamination and drip water are protected.
- the structure described above enables the user to subsequently install the transmitter (17; 17 ';17'') into the device (1; 2; 3).
- the plug can be arranged in a receiving box (not shown) behind the control panel (4').
- a receiving box not shown
- the receptacle and plug on the baking muffle (19) behind the control panel (4 '').
- the transmitter (17; 17 '; 17 ") has a range of approx. 30 meters inside buildings, approx. 300 meters outdoors; the transmission frequency is 433 MHz.
- Information data is transmitted from the transmitters (17; 17 '; 17' ') of the various devices (1; 2; 3) to a mobile sequence display (20).
- This is used by the user to query information about all devices in operation.
- it has a receiver (21), a display control (22), a display (23) and a buzzer (24) (see also FIG. 4).
- Figures 2a-d show the mobile sequence display (20) in various representations. It is enclosed in a two-shell plastic housing (25a, b) and has a flap (26) for receiving an energy source (battery or battery, not shown).
- a clip (27) enables it to be attached to a piece of clothing, a beveled underside (28) allows it to be placed on one level with a good view of the display (23).
- the display (23) is designed as an LC display (23), the individually controllable segments of which enable the display of a text line (29) and a time (30).
- the device type (31), a symbol (32) for the connection to the transmitter (17; 17 '; 17' ') and, in the event of undervoltage, the state of charge (not shown) of the rechargeable battery or the battery can be represented.
- the associated LED (35) remains on. Additional functions can be selected with a second row of buttons (36). A selected additional function is acknowledged by the respective LED (37) lighting up. When an additional function that is not permitted is activated, the associated LED (37) lights up and goes out as soon as the button (36) is released. Using the "+" and “-” buttons (38; 39), temperatures (40) and spin speeds (41) can be set within the limits permitted by the program. After the program has been selected, a delay time can be set by pressing button (40) "Delay start”. The LED (41) "Delay start” next to a display (42) is activated. The set delay time appears in the display (42). The program can then be started with the "START" button (43).
- the time delay is counted down every minute.
- the program starts after the delay time has expired.
- the LED (41) "Delay start” next to the display (42) goes out, the LED (44) "Remaining time” lights up.
- the respective program section is shown in the sequence display (45).
- FIG. 4 shows the components essential for data transmission in an automatic washing machine (3).
- the microprocessor controller (7) passes a data set with a length of 15 bytes to the transmitter (17) at cyclical intervals, which then converts it into the protocol shown below and outputs it at a baud rate of 1200 or 2400 baud.
- the first three bytes (burst) are used to initialize the display control (22) in the mobile sequence display (20).
- the address code stored in the E 2 PROM (12) is then transmitted.
- An address code is also stored in a memory (46) of the display control (22).
- An evaluation circuit (47) integrated in the display control (22) compares the address codes and only allows those transmission protocols for further processing in which a match is found.
- the display can be limited to a selection of household appliances (1; 2; 3) made by the user. In this way, malfunctions caused by devices with the same function in neighboring households are excluded.
- a master receiver can be set up without an evaluation circuit (not shown). With this, all devices can be evaluated and a possible source of error between transmitter and receiver can be determined.
- the address code can be entered and changed by the user himself in the E2PROM (12) of the respective device.
- the input is made using the programming function.
- the device is set to ready for input by a certain switch / key combination, then another key combination is used to enter the data.
- Another input option that is more convenient for the user provides an optical interface between the microprocessor control and the display control (22).
- the "overdosed" LED (48) can be used in a manner known from DE 44 42 967, an LED (49) must be provided on the mobile sequence display (20) as a "transmitter".
- Cyclical emission of the address code from the memory (46) via the LED (49) ensures that the user only has to bring the two parts of the interface (48; 49) together to overwrite the address code.
- the interface (48; 49) in connection with an E2PROM (50) arranged in the display control (22) can also be used to update the program data in the E 2 PROM (11) of the washing machine (3).
- the transmission of time data and data about the running program step or the program end can be dispensed with.
- the measured cooling temperature is sent here and, if this exceeds the set value by a predetermined difference, a warning signal is triggered
- the last two bytes form a checksum and are used to detect and eliminate transmission errors.
- the data is updated cyclically. If the transmission is interrupted so that no valid information is received over a predetermined period of time, for example 60 seconds, the display (23) is updated automatically.
- the display control (22) has a separate sequence control (51), which then automatically updates the display.
- the remaining time is counted down by a time module (52) and stored standard program steps are displayed depending on the remaining time displayed in each case.
- the transmission symbol (32) on the display (23) is deleted. The user will then only notice the transmission loss if the symbol (32) is not shown on the display (23).
- An embodiment not shown in the drawings also uses the time module (52) to alternately communicate the time of day with the program sequence.
- the display (23) shows the program step (53) and the remaining time (54). If several transmitters with the correct address code are received, the display for the individual devices takes place alternately and the device type (31) is also shown (see Fig. 5a-d). If an error occurs in the program sequence, the warning signal emitted by the transmitter is converted into a sound signal by the buzzer (24).
- FIG. 6 shows the control panel (4) of another embodiment of a washing machine designed according to the invention.
- a receptacle opening (55) for the mobile progress indicator (20) is integrated in the switch panel. It is in its rest position in the receiving opening (55) and can be removed from there according to the ballpoint pen principle by pressing on its outward-facing side of the housing.
- the mechanism required for this is known, for example, in the case of remote controls from television or video recorders and is therefore not explained in more detail.
- a contact point which is connected to the battery, is arranged on the housing surface pointing into the interior of the device.
- the battery can be supplied with power via a charging device inside the washing machine, the electrical connection being established via charging contacts in the contact point. In this way, the energy store can be charged in the rest position. (not shown)

Abstract
Description
Die Erfindung betrifft ein Haushaltgerät mit einer Anzeigevorrichtung, mit welcher Informationen, die Restlaufzeit, das Gerät und/oder den Gerätestatus betreffen, räumlich getrennt vom Haushaltgerät darstellbar sind, wobei diese Informationen als Daten von einer vorzugsweise elektronischen Programmsteuerung des Haushaltgerätes über eine Sendeeinrichtung drahtlos an eine in der Anzeigevorrichtung angeordnete Empfangseinrichtung weitergegeben werden. Ein solches Haushaltgerät ist aus dem DE-GM 18 95 053 bekannt.The invention relates to a household appliance with a display device with which information relating to the remaining life, the device and / or the device status can be displayed spatially separately from the household appliance, this information as data from a preferably electronic program control of the household appliance via a transmitter to a wireless device receiving device arranged in the display device are passed on. Such a household appliance is known from DE-GM 18 95 053.
Ca. 50% aller Waschautomaten und Trockner befinden sich außerhalb des Wohnraums. Beim Gebrauch eines solchen Haushaltgerätes ist es für den Benutzer vorteilhaft, auch außerhalb vom Aufstellungsraum des Gerätes eine Information über den Programmfortschritt oder die Restlaufzeit des von ihm eingestellten Programms zu erhalten. Auch bei anderen Geräten, z. B. Herden, Kühlschränken und Geschirrspülautomaten besteht der Wunsch nach einer standortunabhängigen Kontrolle.Approx. 50% of all washing machines and dryers are outside the living room. When using such a household appliance, it is advantageous for the user to receive information about the program progress or the remaining time of the program he has set, even outside the installation room of the appliance. Also with other devices, e.g. B. Cookers, refrigerators and dishwashers, there is a desire for a location-independent control.
Es sind Haushaltgeräte bekannt, bei denen sich an der Bedienblende eine abnehmbare Signaluhr befindet, die vom Benutzer eingestellt und mitgenommen werden kann. Hierbei muß der Benutzer die Programmdauer einschätzen und davon abhängig die Uhr einstellen. Neben der Ungenauigkeit der geschätzten Programmdauer besitzen solche Signaluhren den Nachteil, daß weder der Programmablauf kontrolliert noch Wamsignale abgegeben werden können.Household appliances are known in which there is a detachable signal clock on the control panel which can be set and carried by the user. Here the user has to estimate the program duration and, depending on this, set the clock. In addition to the imprecision of the estimated program duration, such signal clocks have the disadvantage that neither the program sequence can be checked nor doublet signals can be emitted.
Weiterhin ist aus der DE 28 09 112 bekannt, das gesamte Bedienpult eines Haushaltgerätes vom Gerät getrennt anzuordnen und die Übertragung der Steuerbefehle und der Anzeigesignale zwischen dem Bedienpult und der elektronischen Gerätesteuerung drahtlos über Ultraschall oder Infrarotstrahlung vorzunehmen. Für den Benutzer ist es jedoch unbequem, das gesamte Bedienpult mitzuführen.Furthermore, it is known from
Aus der DE 34 04 211 ist eine Anzeigevorrichtung bekannt, bei der das Steuergerät eines Haushaltgerätes Überwachungsfunktionen als kodierte elektrische Signale über die Netzstrom-Leitung an einen Überwachungsempfänger sendet. Eine gleichzeitige Überwachung verschiedener Haushaltgeräte soll durch Benutzung von mehreren Sendekanälen und ein Auswahlschaltwerk im Empfänger realisiert werden. Der Nachteil der vorgenannten Anzeigevorrichtung besteht zum einen in der Abhängigkeit von einem Leitungssystem. Hierdurch wird die Mobilität des Betrachters erheblich eingeschränkt. Außerdem ist gerade die Netzstrom-Leitung sehr anfällig für Störungen durch überlagerte Übertragungen aus Nachbarhäusem, sei es durch gleiche Geräte, Babyphon oder CB-Funk. Zum anderen ist die Verwendung eines Auswahlschaltwerks technisch aufwendig und kann dazu führen, daß die Kontrolle einzelner Geräte vergessen wird.From DE 34 04 211 a display device is known in which the control unit of a household appliance sends monitoring functions as coded electrical signals to a monitoring receiver via the mains power line. Simultaneous monitoring of different household appliances is to be realized by using several transmission channels and a selection switch in the receiver. The disadvantage of the aforementioned display device is on the one hand the dependence on a line system. This considerably limits the viewer's mobility. In addition, the mains power line is particularly susceptible to interference from superimposed transmissions from neighboring houses, be it from the same devices, baby phone or CB radio. The other is the use of a Selector switch technically complex and can lead to the control of individual devices being forgotten.
Die aus dem DE-GM 18 95 053 bekannte Waschmaschine verwendet einen Impulssender und eine Anzeigevorrichtung mit einem Impulsempfänger, um den Zeiger eines Schaltwerks in Abhängigkeit vom Programmstatus zu steuem. Hiermit ist keine Überwachung von verschiedenen Haushaltgeräten möglich.The washing machine known from DE-GM 18 95 053 uses a pulse transmitter and a display device with a pulse receiver in order to control the pointer of a switching mechanism depending on the program status. This means that it is not possible to monitor various household appliances.
Der Erfindung liegt daher das Problem zugrunde, ein Haushaltgerät mit einer Anzeigevorrichtung der eingangs genannten Art zu schaffen, auf der der Benutzer unabhängig vom Aufstellort des Geräts sicher und einfach Informationen über die Daten dieses und weiterer Geräte erhältThe invention is therefore based on the problem of creating a household appliance with a display device of the type mentioned at the beginning, on which the user receives information about the data of this and other devices safely and easily, regardless of the location of the device
Erfindungsgemäß wird dieses Problem durch ein Haushaltgerät mit den im Patentanspruch 1 angegebenen Merkmalen gelöst Zweckmäßige Weiterbildungen und Ausgestaltungen ergeben sich aus den nachfolgenden Unteransprüchen.According to the invention, this problem is solved by a household appliance with the features specified in
Die mit der Erfindung erreichbaren Vorteile werden durch die Verwendung einer eigenen Steuereinrichtung innerhalb der Anzeigevorrichtung erreicht. Vorteilhafterweise wird eine Mikroprozessorsteuerung verwendet, mit welcher die Daten mehrerer gleichzeitig betriebener Haushaltgeräte seriell oder parallel darstellbar sind. Hierdurch kann eine kleine, sehr kompakt aufgebaute Anzeige geschaffen werden, welche die Informationen in übersichtlicher Art und Weise darstellt Desweiteren besteht die Möglichkeit, bereits vorhandene Geräte mit einem Sender nachzurüsten und die Empfangsvorrichtung auch für diese Geräte zu benutzen. Ein weiterer Vorteil besteht darin, daß über die Anzeigevorrichtung alle angeschlossenen Haushaltgeräte auf unbefugte Benutzung kontrolliert werden können.The advantages achievable with the invention are achieved by using a separate control device within the display device. A microprocessor control is advantageously used, with which the data of several simultaneously operated household appliances can be represented in series or in parallel. In this way, a small, very compact display can be created, which displays the information in a clear manner. Furthermore, there is the possibility of retrofitting existing devices with a transmitter and also using the receiving device for these devices. Another advantage is that all connected household appliances can be checked for unauthorized use via the display device.
Eine besonders vorteilhafte Weiterbildung der Erfindung besteht darin, daß die Daten einen Adreßcode beinhalten und daß in der Steuervorrichtung eine Auswerteschaltung integriert ist, welche nur die Anzeige von Daten derjenigen Haushaltgeräte zuläßt, die diesen Adreßcode senden. Hierdurch werden in einfachster Weise Störungen durch andere Funksignale unterdrückt, insbesondere eine Überlagerung von Daten, welche durch Geräte mit gleichen Anzeigeeinrichtungen aus der Nachbarschaft gesendet werden.A particularly advantageous development of the invention consists in the fact that the data contain an address code and that an evaluation circuit is integrated in the control device which only permits the display of data of those household appliances which send this address code. In this way, interference from other radio signals is suppressed in the simplest way, in particular an overlay of data which are sent from devices with the same display devices from the neighborhood.
Es ist weiterhin vorteilhaft, den Adreßcode in einem nichtflüchtigen Speicher der elektronischen Programmsteuerung abzulegen und von dort an die Sendeeinrichtung weiterzugeben. Hierdurch ist eine einfache Anpassung eines nachgekauften Gerätes an eine bereits vorhandene Anzeigevorrichtung möglich, welche auch vom Benutzer selbst vorgenommen werden kann. Besonders vorteilhafte Ausgestaltungen der Erfindung ermöglichen die Änderung des Adreßcodes mit den Bedienelementen des Geräts oder in Verbindung mit einer Schnittstelle zwischen der elektronischen Programmsteuerung und der Anzeigesteuerung. Damit kann der Adreßcode zusätzlich in einem nichtflüchtigen Speicher der Anzeigesteuerung abgelegt und von dort über die Schnittstelle in den nichtflüchtigen Speicher der elektronischen Programmsteuerung überschrieben werden.It is also advantageous to store the address code in a non-volatile memory of the electronic program control and to forward it from there to the transmission device. This makes it easy to adapt a purchased device to an existing display device, which can also be carried out by the user himself. Particularly advantageous refinements of the invention enable the address code to be changed using the operating elements of the device or in connection with an interface between the electronic program control and the display control. The address code can thus also be stored in a non-volatile memory of the display control and can be overwritten from there via the interface into the non-volatile memory of the electronic program control.
In einer weiteren vorteilhaften Ausgestaltung der Erfindung wird die Schnittstelle zwischen der elektronischen Programmsteuerung und der Anzeigesteuerung dazu benutzt, Prozeßparameter auszutauschen. Hierdurch kann die Anzeigevorrichtung als Speicher- und Übertragungsmedium für ein Updating von Programmen benutzt werden, d. h., es können aktuelle Prozeßparameter von neuen Steuerungsgenerationen in Geräte älteren Herstelldatums überschrieben werden.In a further advantageous embodiment of the invention, the interface between the electronic program control and the display control is used to exchange process parameters. As a result, the display device can be used as a storage and transmission medium for updating programs, i. that is, current process parameters of new control generations in devices with older manufacturing dates can be overwritten.
Daneben ist es vorteilhaft, die Anzeigevorrichtung mit einem LC-Display auszustatten, in welchem die Informationen, die die einzelnen Geräte betreffen, zyklisch in festgelegter Reihenfolge dargestellt werden. Hierdurch erhält der Benutzer ohne weiteres Zutun nacheinander Informationen über alle in Betrieb befindlichen Geräte.In addition, it is advantageous to equip the display device with an LC display, in which the information relating to the individual devices is shown cyclically in a predetermined order. As a result, the user receives information about all the devices in operation one after the other without any further action.
Eine andere vorteilhafte Weiterbildung der Erfindung beinhaltet, daß die Anzeigesteuerung eine separate Ablaufsteuerung besitzt, welche bei Unterbrechung der Verbindung zur Sendeeinrichtung über einen vorbestimmten Zeitraum eine selbsttätige Aktualisierung der Anzeige vomimmt. Durch Verwendung von Daten von Standardprogrammen kann so durch das Herunterzählen der Restzeit eine relativ genau geschätzte Anzeige des Programmstatus geboten werden.Another advantageous development of the invention includes that the display control has a separate sequence control which, when the connection to the transmitting device is interrupted, automatically updates the display for a predetermined period of time. By using data from standard programs, a relatively accurately estimated display of the program status can be provided by counting down the remaining time.
In einer weiteren vorteilhaften Ausgestaltung der Erfindung ist an der elektronischen Programmsteuerung eine für den Benutzer frei zugängliche Schnittstelle angeordnet, an der die Sendeeinrichtung in einer Haltevorrichtung mit der Programmsteuerung kontaktierbar ist. Die Anzeigevorrichtung kann hierdurch als separates Zubehörteil angeboten werden und der Sender auch nachträglich vom Benutzer selbst in das Gerät eingebaut werden.In a further advantageous embodiment of the invention, an interface that is freely accessible to the user is arranged on the electronic program control, at which the transmitting device can be contacted with the program control in a holding device. The display device can thus be offered as a separate accessory and the transmitter can also be subsequently installed by the user in the device.
Daneben ist es vorteilhaft, der Programmsteuerung ein weitere Empfangseinrichtung im Geräteinneren zuzuordnen. Hierdurch kann eine Datenübertragung zur Kommunikation verschiedener Haushaltgeräte untereinander benutzt werden. Damit können Waschmaschinen, Trockner, Geschirrspülautomaten und Herde ihre Heizphasen oder Programmstarts so koordinieren, daß eine bestimmte Leistungsaufnahme aus dem Netz nicht überschritten wird. Dies hat wiederum den Vorteil, daß mehrere Geräte an einem einzigen Netzstromkreis betrieben werden können. Außerdem kann durch ein "Time Sharing" der Heizungen der Spitzenverbrauch vermindert werden.In addition, it is advantageous to assign a further receiving device inside the device to the program control. As a result, data transmission can be used for communication between different household appliances. This allows washing machines, dryers, dishwashers and cookers to coordinate their heating phases or program starts so that a certain power consumption from the network is not exceeded. This in turn has the advantage that several devices can be operated on a single mains circuit. In addition, a "time sharing" of the heaters can reduce the peak consumption.

Figur 1 zeigt schematisch die Funktionsweise bei erfindungsgemäß ausgebildeten Haushaltgeräten, im dargestellten Beispiel bei einem Herd (1), einem Geschirrspülautomaten (2) und einem Waschautomaten (3). Diese Haushaltgeräte besitzen alle folgenden prinzipiellen Aufbau:Figure 1 shows schematically the operation of household appliances designed according to the invention, in the example shown with a stove (1), an automatic dishwasher (2) and an automatic washing machine (3). These household appliances all have the following basic structure:
Im oberen Frontbereich der Geräte ist eine Bedienblende (4;4';4") mit Schaltelementen (5,5',5") zur Auswahl eines Programms und/oder speziellen Funktionen angeordnet. Von dort werden Schaltbefehle über Steuerleitungen (6;6';6") an eine Mikroprozessorsteuerung (7;7';7") weitergegeben, die sie dann in entsprechende Programme umsetzt. Dazu beeinflußt die Mikroprozessorsteuerung (7;7';7") zeitabhängig und zustandsabhängig verschiedene gerätespezifische Aktoren des Haushaltgerätes, in der Regel Heizungen (8) und Motoren (9). Die Steuergrößen sind teilweise als feste Prozeßparameter in einem ROM (10;10';10") und teilweise als veränderbare Prozeßparameter in einem ersten programmierbaren, nichtflüchtigen Speicher, beispielsweise einem E2PROM (11;11';11'') abgelegt. In einem zweiten E2PROM (12;12';12") ist ein Adreßcode abgespeichert, dessen Funktion später erklärt wird. Neben den Schaltelementen (5;5';5") besitzt die Bedienblende (4;4',4") Anzeigeelemente (13;13';13"), welche dem Benutzer Informationen darstellen, die mit der Programmwahl und dem Programmablauf zusammenhängen. Auch diese werden von der Mikroprozessorsteuerung (7;7';7'') in bekannter Weise angesteuert.A control panel (4; 4 '; 4 ") with switching elements (5.5', 5") for selecting a program and / or special functions is arranged in the upper front area of the devices. From there, switching commands are passed on via control lines (6; 6 '; 6 ") to a microprocessor control (7; 7';7"), which they then convert into corresponding programs. For this purpose, the microprocessor control (7; 7 '; 7 ") influences time-dependent and condition-dependent various device-specific actuators of the household appliance, usually heaters (8) and motors (9). The control variables are partly as fixed process parameters in a ROM (10; 10'; 10 ") and partially stored as changeable process parameters in a first programmable, non-volatile memory, for example an E 2 PROM (11; 11 ';11"). An address code is stored in a second E 2 PROM (12; 12 '; 12 "), the function of which will be explained later. In addition to the switching elements (5; 5';5"), the control panel (4; 4 ', 4 ") Display elements (13; 13 '; 13 "), which represent information to the user which is related to the program selection and the program sequence. These are also controlled in a known manner by the microprocessor control (7; 7 ';7'').
Von der Mikroprozessorsteuerung (7;7';7") sind erfindungsgemäß weitere Steuerleitungen (14;14';14'') an einen Stecker (15) im Bereich der Bedienblende (4;4';4") geführt. Desweiteren befindet sich dorf eine Halterung (16), in die ein Sender (17;17';17") eingesetzt und mit dem Stecker (15) kontaktiert werden kann (s. Figur 3). Die Halterung ist durch eine Abdeckplatte (18) verschließbar, so daß der Stecker (15) und der Sender (17;17';17'') vor Verschmutzungen und Tropfwasser geschützt werden. Der vorbeschriebene Aufbau ermöglicht dem Benutzer einen eigenhändigen nachträglichen Einbau des Senders (17;17';17'') in das Gerät (1;2;3). Bei Geschirrspülmaschinen (2), die als Einbaugeräte oft mit einer abnehmbaren Bedienblende (4') ausgestattet sind, kann der Stecker in einem Aufnahmekasten (nicht dargestellt) hinter der Bedienblende (4') angeordnet sein. Bei Einbauherden (1) oder Einbaubackofen wiederum ist es vorteilhaft, den Aufnahmekasten samt Stecker auf der Backmuffel (19) hinter der Bedienblende (4'') anzuordnen. Zum Einbau des Senders (17") ist dann die Verbindung zum Möbelgehäuse zu lösen und das Gerät nach vom zu ziehen (nicht dargestellt).According to the invention, further control lines (14; 14 ';14'') are led from the microprocessor control (7; 7'; 7 ") to a plug (15) in the area of the control panel (4; 4 ';4"). Furthermore, there is a holder (16) in which a transmitter (17; 17 '; 17 ") can be inserted and contacted with the plug (15) (see FIG. 3). The holder is covered by a cover plate (18). closable, so that the plug (15) and the transmitter (17; 17 ';17'') from contamination and drip water are protected. The structure described above enables the user to subsequently install the transmitter (17; 17 ';17'') into the device (1; 2; 3). In dishwashers (2), which are often fitted as built-in devices with a removable control panel (4 '), the plug can be arranged in a receiving box (not shown) behind the control panel (4'). In the case of built-in cookers (1) or built-in ovens, it is advantageous to arrange the receptacle and plug on the baking muffle (19) behind the control panel (4 ''). To install the transmitter (17 "), the connection to the furniture housing must then be released and the device pulled away (not shown).
Der Sender (17;17';17") besitzt innerhalb von Gebäuden eine Reichweite von ca. 30 Metem, im Freien ca. 300 Meter; die Sendefrequenz beträgt 433 MHz.The transmitter (17; 17 '; 17 ") has a range of approx. 30 meters inside buildings, approx. 300 meters outdoors; the transmission frequency is 433 MHz.
Von den Sendem (17;17';17'') der verschiedenen Geräte (1;2;3) werden Informationsdaten zu einer mobilen Ablaufanzeige (20) übertragen. Diese dient dem Benutzer zur Abfrage von Informationen über alle in Betrieb befindlichen Geräte. Sie besitzt hierzu einen Empfänger (21), eine Anzeigesteuerung (22) ein Display (23) und einen Summer (24) (s. a. Figur 4).Information data is transmitted from the transmitters (17; 17 '; 17' ') of the various devices (1; 2; 3) to a mobile sequence display (20). This is used by the user to query information about all devices in operation. For this purpose, it has a receiver (21), a display control (22), a display (23) and a buzzer (24) (see also FIG. 4).
Die Figuren 2a-d zeigen die mobile Ablaufanzeige (20) in verschiedenen Darstellungen. Sie ist in ein zweischaliges Kunststoffgehäuse (25a,b) eingefaßt und besitzt eine Klappe (26) zur Aufnahme eines Energieträgers (Akku oder Batterie, nicht dargestellt). Ein Clip (27) ermöglicht das Anstecken an ein Kleidungsstück, eine abgeschrägte Unterseite (28) ein Abstellen auf einer Ebene mit guter Einsicht auf das Display (23). Das Display (23) ist als LC-Display (23) ausgebildet, dessen einzeln ansteuerbare Segmente die Darstellung einer Textzeile (29) und einer Zeit (30) ermöglichen. Außerdem ist der Gerätetyp (31), ein Symbol (32) für die Verbindung zum Sender (17;17';17'') und bei Unterspannung der Ladezustand (nicht dargestellt) des Akkus oder der Batterie darstellbar.Figures 2a-d show the mobile sequence display (20) in various representations. It is enclosed in a two-shell plastic housing (25a, b) and has a flap (26) for receiving an energy source (battery or battery, not shown). A clip (27) enables it to be attached to a piece of clothing, a beveled underside (28) allows it to be placed on one level with a good view of the display (23). The display (23) is designed as an LC display (23), the individually controllable segments of which enable the display of a text line (29) and a time (30). In addition, the device type (31), a symbol (32) for the connection to the transmitter (17; 17 '; 17' ') and, in the event of undervoltage, the state of charge (not shown) of the rechargeable battery or the battery can be represented.
Die nähere Funktionsweise der Anzeigevorrichtung bei einem Waschautomaten (3) ist anhand der Darstellung einer Bedienblende (4) (Figur 3) erklärt. Nach dem Einschalten der Maschine mit dem "Ein/Aus"-Druckschalter (33) leuchten die den Programmtasten (34) zugehörigen LED's (35) auf, um den Benutzer darauf hinzuweisen, welche Programme gewählt werden können. Dies sind die Programme:
- Koch-/Buntwäsche
- Pflegeleicht
- Pflegeleicht Fein
- Wolle
- Miniprogramm
- Stärken
- Hot wash Coloureds
- Easy care
- Fine and easy to care
- Wool
- Applet
- Strengthen
Wird ein Programm angewählt, bleibt die zugehörige LED (35) eingeschaltet. Mit einer zweiten Reihe von Tasten (36) können Zusatzfunktionen angewählt werden. Eine angewählte Zusatzfunktion wird durch Aufleuchten der jeweiligen LED (37) quittiert. Bei Betätigen einer nicht erlaubten Zusatzfunktion leuchtet die zugehörige LED (37) auf und erlischt, sobald die Taste (36) wieder losgelassen wird. Mittels "+" und "-" Tasten (38;39) können Temperaturen (40) und Schleuderdrehzahlen (41) in dem vom Programm zugelassenen Grenzen eingestellt werden. Nach erfolgter Programmwahl kann durch Betätigen der Taste (40) "Startvorwahl" eine Verzögerungszeit eingestellt werden. Die LED (41) "Startvorwahl" neben einem Display (42) wird angesteuert Im Display (42) erscheint die eingestellte Verzögerungszeit Danach kann das Programm durch die "START"-Taste (43) gestartet werden. Die Zeitvorwahl wird im Minutentakt heruntergezählt. Nach Ablauf der Verzögerungszeit startet das Programm. Die LED (41) "Startvorwahl" neben dem Display (42) erlischt, es leuchtet die LED (44) "Restzeit". In der Ablaufanzeige (45) wird der jeweilige Programmabschnitt angezeigt.If a program is selected, the associated LED (35) remains on. Additional functions can be selected with a second row of buttons (36). A selected additional function is acknowledged by the respective LED (37) lighting up. When an additional function that is not permitted is activated, the associated LED (37) lights up and goes out as soon as the button (36) is released. Using the "+" and "-" buttons (38; 39), temperatures (40) and spin speeds (41) can be set within the limits permitted by the program. After the program has been selected, a delay time can be set by pressing button (40) "Delay start". The LED (41) "Delay start" next to a display (42) is activated. The set delay time appears in the display (42). The program can then be started with the "START" button (43). The time delay is counted down every minute. The program starts after the delay time has expired. The LED (41) "Delay start" next to the display (42) goes out, the LED (44) "Remaining time" lights up. The respective program section is shown in the sequence display (45).
Figur 4 zeigt die für die Datenübertragung wesentlichen Bauteile bei einem Waschautomaten (3). Während des Programmablaufs gibt die Mikroprozessorsteuerung (7) in zyklischen Abständen einen Datentsatz mit der Länge von 15 Byte an den Sender (17) weiter, der ihn dann in das nachstehend dargestellte Protokoll umwandelt und mit einer Baudrate von 1200 oder 2400 Baud abgibt.
Die ersten drei Bytes (Burst) dienen zur Initialisierung der Anzeigesteuerung (22) in der mobilen Ablaufanzeige (20). Danach wird der im E2PROM (12) abgelegte Adreßcode übermittelt. In einem Speicher (46) der Anzeigesteuerung (22) ist ebenfalls ein Adreßcode abgelegt. Eine in der Anzeigesteuerung (22) integrierte Auswerteschaltung (47) vergleicht die Adreßcodes und läßt nur diejenigen Sendeprotokolle zur Weiterverarbeitung zu, bei denen Übereinstimmung festgestellt wird. Hierdurch kann die Anzeige auf eine vom Benutzer getroffene Auswahl von Haushaltgeräten (1;2;3) beschränkt werden. Auf diese Weise sind Störungen durch funktionsgleiche Geräte in Nachbarhaushalten ausgeschlossen. Für Kundendiensttechniker kann ein Master-Empfänger ohne Auswerteschaltung eingerichtet werden (nicht dargestellt). Mit diesem können alle Geräte ausgewertet und damit eine eventuelle Fehlerquelle zwischen Sender und Empfänger bestimmt werden.The first three bytes (burst) are used to initialize the display control (22) in the mobile sequence display (20). The address code stored in the E 2 PROM (12) is then transmitted. In An address code is also stored in a memory (46) of the display control (22). An evaluation circuit (47) integrated in the display control (22) compares the address codes and only allows those transmission protocols for further processing in which a match is found. As a result, the display can be limited to a selection of household appliances (1; 2; 3) made by the user. In this way, malfunctions caused by devices with the same function in neighboring households are excluded. For customer service technicians, a master receiver can be set up without an evaluation circuit (not shown). With this, all devices can be evaluated and a possible source of error between transmitter and receiver can be determined.
Der Adreßcode kann vom Benutzer selbst in das E2PROM (12) des jeweiligen Geräts eingegeben und auch geändert werden. Die Eingabe erfolgt per Programmierfunktion. Hierzu wird das Gerät durch eine bestimmte Schalter-/Tastenkombination in Eingabebereitschaft versetzt, danach erfolgt durch eine andere Tastenkombination die Dateneingabe. Eine andere, für den Benutzer bequemere Eingabemöglichkeit sieht eine optische Schnittstelle zwischen der Mikroprozessorsteuerung und der Anzeigesteuerung (22) vor. Beim Gerät kann beispielsweise die "Überdosiert"-LED (48) in einer aus der DE 44 42 967 bekannten Art und Weise benutzt werden, an der mobilen Ablaufanzeige (20) muß eine LED (49) als "Sender" vorgesehen werden. Durch zyklisches Ausstrahlen des Adreßcodes vom Speicher (46) über die LED (49) ist gewährleistet, daß der Benutzer nur noch die beiden Teile der Schnittstelle (48;49) zusammenbringen muß, um den Adreßcode zu überschreiben. Außer zur Eingabe des Adreßcodes kann die Schnittstelle (48;49) in Verbindung mit einem in der Anzeigesteuerung (22) angeordneten E2PROM (50) auch für ein Update der Programmdaten im E2PROM (11) des Waschautomaten (3) genutzt werden.The address code can be entered and changed by the user himself in the E2PROM (12) of the respective device. The input is made using the programming function. For this purpose, the device is set to ready for input by a certain switch / key combination, then another key combination is used to enter the data. Another input option that is more convenient for the user provides an optical interface between the microprocessor control and the display control (22). In the device, for example, the "overdosed" LED (48) can be used in a manner known from
Hierauf folgen die für die Anzeige relevanten Daten, nämlich der Gerätetyp, die Restzeit und der Gerätestatus. Als Gerätestatus werden folgende Informationen gesendet:
- Im Betriebszustand der aktuelle Programmschritt
- Bei Auftreten eines Fehlers zunächst ein Wamsignal, danach die Art des Fehlers
- Zum Programmende ein Wamsignal
- The current program step in the operating state
- If an error occurs, first a warning signal, then the type of error
- A warning signal at the end of the program
Bei Kühlgeräten kann auf die Übermittlung von Zeitdaten und Daten über den ablaufenden Programmschritt oder das Programmende verzichtet werden. Hier wird die gemessene Kühltemperatur gesendet und, wenn diese den Einstellwert um eine vorgegebene Differenz überschreitet, ein Wamsignal ausgelöstIn the case of cooling devices, the transmission of time data and data about the running program step or the program end can be dispensed with. The measured cooling temperature is sent here and, if this exceeds the set value by a predetermined difference, a warning signal is triggered
Die letzten zwei Bytes bilden eine Checksumme und werden zur Erkennung und Beseitigung von Übertragungsfehlem benutzt.The last two bytes form a checksum and are used to detect and eliminate transmission errors.
Die Daten werden zyklisch aktualisiert Wird die Übertragung unterbrochen, so daß über einen vorbestimmten Zeitraum, beispielsweise 60 Sekunden, keine gültigen Informationen empfangen werden, wird das Display (23) selbständig aktualisiert Hierzu besitzt die Anzeigesteuerung (22) eine separate Ablaufsteuerung (51), welche dann eine selbsttätige Aktualisierung der Anzeige vomimmt. Zu diesem Zweck wird die Restzeit von einem Zeitmodul (52) heruntergezählt und es werden gespeicherte Standardprogrammschritte in Abhängigkeit von der jeweils angezeigten Restzeit zur Anzeige gebracht. Das Übertmgungssymbol (32) auf dem Display (23) wird gelöscht Der Benutzer wird den Übertragungsverlust dann nur durch die fehlende Anzeige des Symbols (32) im Display (23) merken. Eine in den Zeichnungen nicht dargestellte Ausführungsform benutzt das Zeitmodul (52) zusätzlich dazu, wechselweise zum Programmablauf die Tageszeit mitzuteilen.The data is updated cyclically. If the transmission is interrupted so that no valid information is received over a predetermined period of time, for example 60 seconds, the display (23) is updated automatically. For this purpose, the display control (22) has a separate sequence control (51), which then automatically updates the display. For this purpose, the remaining time is counted down by a time module (52) and stored standard program steps are displayed depending on the remaining time displayed in each case. The transmission symbol (32) on the display (23) is deleted. The user will then only notice the transmission loss if the symbol (32) is not shown on the display (23). An embodiment not shown in the drawings also uses the time module (52) to alternately communicate the time of day with the program sequence.
Das Display (23) zeigt bei korrektem Programmablauf den Programmschritt (53) und die Restzeit (54) an. Werden mehrere Sender mit dem richtigen Adreßcode empfangen, erfolgt die Anzeige für die einzelnen Geräte wechselweise und es wird zusätzlich der Gerätetyp (31) dargestellt (s. Figur 5a-d). Tritt ein Fehler im Programmablauf auf, wird das vom Sender ausgestrahlte Wamsignal vom Summer (24) in ein Tonsignal umgewandelt.When the program is running correctly, the display (23) shows the program step (53) and the remaining time (54). If several transmitters with the correct address code are received, the display for the individual devices takes place alternately and the device type (31) is also shown (see Fig. 5a-d). If an error occurs in the program sequence, the warning signal emitted by the transmitter is converted into a sound signal by the buzzer (24).
Figur 6 zeigt die Bedienblende (4) einer anderen Ausführungsform eines erfindungsgemäß ausgebildeten Waschautomaten. Neben den Bedienelementen ist in der Schalterblende eine Aufnahmeöffnung (55) für die mobile Ablaufanzeige (20) integriert. Sie befindet sich in ihrer Ruhestellung in der Aufnahmeöffnung (55) und kann von dort nach dem Kugelschreiberprinzip durch Druck auf seine nach außen gerichtete Gehäuseseite entnommen werden. Der hierzu erforderliche Mechanismus ist beispielsweise bei Fembedienungen von Femsehem oder Videorecordem bekannt und wird deshalb nicht näher erläutert.Figure 6 shows the control panel (4) of another embodiment of a washing machine designed according to the invention. In addition to the control elements, a receptacle opening (55) for the mobile progress indicator (20) is integrated in the switch panel. It is in its rest position in the receiving opening (55) and can be removed from there according to the ballpoint pen principle by pressing on its outward-facing side of the housing. The mechanism required for this is known, for example, in the case of remote controls from television or video recorders and is therefore not explained in more detail.
Auf der ins Geräteinnere zeigenden Gehäusefläche ist eine Kontaktstelle angeordnet, die mit dem Akku in Verbindung steht Die Stromzufuhr für den Akku kann über eine Ladevorrichtung innerhalb der Waschmaschine erfolgen, wobei die elektrische Verbindung über Ladekontakte in der Kontaktstelle hergestellt wird. Auf diese Weise kann der Energiespeicher in Ruhestellung aufgeladen werden. (nicht dargestellt)A contact point, which is connected to the battery, is arranged on the housing surface pointing into the interior of the device. The battery can be supplied with power via a charging device inside the washing machine, the electrical connection being established via charging contacts in the contact point. In this way, the energy store can be charged in the rest position. (not shown)
