One parameter relates to the time of day and/or the date and/or the season at the site of installation of the cooking appliance. A large number of programs which are preselected by means of the parameters can be automatically displayed on a display device after the cooking appliance is switched on, and one of these displayed programs can be selected by means of at least one operator control device. The invention also relates to a method for setting a cooking appliance of this type.
Description

The present invention relates to a cooking appliance in which a plurality of programs is pre-selectable in dependence on at least one parameter, at least one first parameter being determined by the time of day at the installation location of the cooking appliance, and/or at least one second parameter being determined by the day at the installation location of the cooking appliance, and/or at least one third parameter being determined by the season at the installation location of the cooking appliance, and a method for setting such a cooking appliance.


A cooking appliance is known from EP 0 971 173 A1, in which a country program list is displayed on a display, in each case in a country-specific order of control programs and/or control program descriptors. The country-specific different cooking and food customs may thus be taken into consideration. For example, the recipes may be placed in the order which reflects the average frequency of use for every national language and thus for each country in which the cooking appliance may be used. This means that, for example, the preparation of a pork roast occurs more frequently in Germany than in Turkey, and therefore the recipe for the pork roast appears at a significantly earlier point in the German country program list than in the corresponding Turkish list. The selection of the recipes by an operator is thus accelerated, because the first recipe of the country program list displayed at the start of the programming mechanism is the one most frequently used in this country. By further actuation of an input unit, with increasing duration, an operator reaches recipes of which the frequency of use is lower in the particular country. This does make the operability easier per se, but is not yet satisfactory for restaurant chains in particular.


An electronic control device for a domestic oven having a memory unit, in which cooking programs for a plurality of foods are stored, is known from EP 1 758 000 A1 (no prior publication). In dependence on the language or the region of the installation location of the oven, a selected partial set of the available cooking programs is provided for selection by a user according to the linguistic or region-specific conditions at the installation location.


A program-controlled domestic appliance having a stockpile of country-specific program sequences, which are stored in a memory of the device, is known from DE 101 17 292 A1. An assigned set of country-specific programs is provided for selection by the user through the selection of the display language of the appliance by a user.


U.S. Pat. No. 6,236,974 B1 discloses a computer-based system for domestic planning, which displays selected menu suggestions on the basis of information about personal preferences of the household members.


A cooking appliance according to the pre-amble of claim 1, having an electronic control unit and a read device is disclosed in DE 94 00 564 U1. Cooking programs may be stored in an internal memory of the cooking appliance. The subsequent recording of further cooking programs into the internal memory is made possible by a data carrier insertable into the read device and is thus meant to take seasonal variations into consideration, so that one and the same appliance may be used at Christmas time for producing gingerbread men and at Easter for producing Easter bunnies and the like, for example.


Furthermore, a domestic appliance controller is described in U.S. Pat. No. 5,808,278 A, which automatically deactivates those operating and display elements of a domestic appliance which do not correspond to Orthodox Jewish provisions on the Sabbath. Actually, this is to prevent an oven from being able to be used to cook food on the Sabbath.


The object of the present invention is therefore to refine the appliance according to the invention in such a way that it is operable rapidly, easily, and error-free, in particular for operating personnel of restaurant chains.


This object is achieved according to the invention in that, after the appliance is turned on, the plurality of the programs preselected via the first, second, and/or third parameters is automatically displayable on at least one display device, and one of these displayed programs is selectable via at least one operating device.


It may be provided that the programs are cooking programs and/or cleaning programs, and/or that the at least one first parameter is determined by the time of day at the installation location of the cooking appliance, and/or that the day at the installation location of the cooking appliance is selected from work day or holiday, and/or that the season is selected by the time of year and/or the weather.


It is also proposed by the invention that at least one fourth parameter be determined by the region of the installation location of the cooking appliance, and/or at least one fifth parameter be determined by the religion, in particular the geographic religion, of the customers to be served at the installation location of the cooking appliance, and/or at least one sixth parameter be determined by the language at the installation location of the cooking appliance.


The invention again provides that the plurality of programs is also selectable as a function of the fourth and/or fifth and/or sixth parameters.


According to the invention, it can be provided that the order and/or configuration of the programs on the display device may also be fixed by the average frequency of use, wherein the average frequency of use depends in particular on the first and/or second and/or third parameters, preferably the first and/or second and/or third and fourth and/or fifth and/or sixth parameters, and/or can be updated in operation of the cooking appliance.


Cooking appliances according to the invention may be further distinguished by a first area of the display device in which the preselected programs are displayed; and/or a second area of the display device in which the first and/or second and/or third parameters, preferably the first and/or second and/or third and fourth and/or fifth and/or sixth parameters is/are displayed; and/or a third area of the display device, in which at least one further program is displayed, which is preselectable, settable, and/or changeable by an operator.


Furthermore, it is proposed that one of the displayed programs be selectable via a first area of the operating device; and/or that the first and/or second and/or third parameters, preferably the first and/or second and/or third and fourth and/or fifth and/or sixth parameters be selectable and/or changeable via a second area of the operating device; and/or that one may change to another operating menu level via a third area of the operating device.


It is preferable according to the invention that the display device and operating device are at least partially comprised by a touch screen.


Further embodiments of a cooking appliance according to the invention are characterized by a timekeeper, such as a clock, and/or a positioning system, based on GPRS, for example, and/or at least one sensor, in particular for detecting the weather at the installation location of the cooking appliance, and/or a selection device for selecting the first, second and/or third parameters, preferably the first and/or second and/or third and fourth and/or fifth and/or sixth parameters, each operationally linked to a regulator or control device.


It can be provided that the regulator or control device is operationally linked to the display device and/or the operating device.


Furthermore, cooking appliances according to the invention are proposed which are additionally characterized by at least one heating device for heating a cooking chamber, at least one device for introducing moisture into the cooking chamber, at least one device for exhausting moisture from the cooking chamber, at least one cooling device for cooling the cooking chamber, at least one cleaning device for cleaning the cooking chamber, and/or at least one sensor for detecting at least one characteristic variable in the cooking chamber, in particular operationally linked in each case to the regulator or control device.


At least one first memory device inside the cooking appliance and/or at least one second memory device outside the cooking appliance, in particular each able to be operationally linked to the regulator or control device, may be provided according to the invention.


Furthermore, it may be provided that the cooking appliance can be operationally linked to at least one personal computer, the Internet, a data carrier, for example, in the form of a USB flash drive, wherein the second memory device is preferably comprised by the personal computer and/or the data carrier.


A method for setting a cooking appliance according to the invention is also provided by the invention, which is characterized in that the preselected programs at the installation location are automatically preselected from stored programs, wherein the preselected programs can preferably be changed and/or supplemented manually, in particular after input of a specific first access code.


It can be provided that the first and/or second and/or third parameters, preferably the first and/or second and/or third and fourth and/or fifth and/or sixth parameters can be changed, in particular after input of a second access code, wherein the first and the second access codes are preferably selected as identical.


Finally, it is also proposed by the invention that the order and/or configuration of the preselected programs on a display device be determined by the frequency of use thereof, the frequency of use preferably being updated during the operation of the cooking appliance and/or fixed in dependence on experiential values, in particular in relation to the first, second and/or third parameters, preferably the first and/or second and/or third and fourth and/or fifth and/or sixth parameters.


The invention thus provides a reduction of the steps for selecting a program, namely in that, for example, cooking programs specially preselected by a restaurant chain automatically appear on a display device of a cooking appliance, sorted according to frequency of use, immediately after the cooking appliance is turned on, as a function of a time of day. By this linkage of, in particular, times of day and time spans stored in the cooking appliance, the cooking programs most frequently requested in these time spans by customers of said restaurant chain are thus automatically offered to operating personnel, for example, using pictogram symbols, on an uppermost operating level of the display device. For example, from 6:00 a.m. to 10:00 a.m. on work days, only a typical breakfast may be prepared using the cooking appliances according to the invention. The precise specifications of the times and time spans may be predefined by the restaurant chain, so that the customers receive their familiar foods independently of the operating personnel.


The cooking appliance according to the invention may be flexibly adapted to the particular wishes of the cooking appliance operator, in particular a restaurant chain, for example, by accommodating special foods of a season, a region, and the like in the preselected programs.
