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)
