DE2850366A1 - Table top electric grill unit - with programmed cooking control and manual keyboard for entering information relating to program to be operated on by microprocessor - Google Patents

Abstract

The table top grill unit has an automatic controller, which can be used to regulate the cooking temp., the start of cooking and the cooking duration. The controller is incorporated in the base (2) of the grill unit and is programmed by data entered via a manual keyboard (7, 9) in the front control plate (3). The latter also incorporates control and/or signal lights (6, 10) e.g indicating when the grill is on, or cooking is complete, together with a clock (8). The front control plate (3) pref. also has a viewing window (4) through which an endless information band is visible, to provide recipe and/or programming information. Pref. the cooking controller comprises a microprocessor.

Description

Grill device

The invention relates to a grill device in the preamble of Art.

Well-known grills, as they are used in particular in the household, have various manually operated actuators for setting the desired ones Cooking parameters such as cooking temperature, start of cooking and cooking time. A change the set cooking parameters during a cooking process and / or a discontinuous one Course of the cooking process, for example post-browning using an emitter from since Roast pieces that have been cooked for a long time and then kept warm at a reduced temperature a renewed intervention of the operator 0 The object of the invention is therein, with a grill device of the type mentioned at the beginning, a fully automatic, free To enable a predefinable course of the cooking process.

According to the invention, the object is achieved by the characterizing features of claim 1 solved.

In the grill device according to the invention, when inserting the Food Enter the desired cooking program manually, if necessary several, through different Cooking parameters and / or the use of different cooking elements of the grill device May contain cooking levels, e.g. pre-grilling, finish grilling, keeping warm, post-browning. This cooking program, once set, runs after a switch-on time that can also be specified completely automatically. In this way, not only operating errors such as e.g. Burning or drying out of the food, definitely excluded, but it also gets the operator completely from overseeing the cooking process relieved.

The accommodation of the automatically working cooking program control device together with the associated keypad device for program input into the base part the grill device has the advantage that these assemblies on the one hand from the heat part of the grill device are separated and thus protected against overheating and on the other hand are easily accessible.

In a preferred manner, control and / or signal lights can also be used as well as an information carrier for operating instructions and cooking recipes in one Front panel of the base part can be accommodated. Convenient trips are available as keypads a field for entering the desired cooking levels including their sequence as well as the desired cooking parameters and another field for numerical input the amount of the cooking parameters is available. By using a microprocessor as Cooking program control device, the cost-benefit ratio in the inventive Keep the table grill in an extremely affordable setting.

The invention is explained in more detail with reference to the drawing. The only Figure shows a front view of a preferred embodiment of one according to the invention trained grill device.

The grill device shown has an upper housing part 1, which is designed and designed in the usual way for receiving and cooking food. The housing part 1 rests on a base part 2, which on its front with a removable front plate 3 is covered. In the base part 2 is not shown Way an automatically working, freely programmable cooking program control device housed in the form of a microprocessor. The microprocessor consists of the usual Way of an input unit, a clock, one with the input unit and Erasable read-only memory logically linked to the clock generator, e.g. an EPROM, an arithmetic unit connected to the read-only memory and the clock, which is operated by the Fostwertspeicher retrieves data and enters this data, as well as an input unit, which convert the digital control commands of the arithmetic unit into analog control signals for converts the various downstream actuators of the grill device.

The input unit of the microprocessor comprises in the illustrated Example case two keypads 7 and 9 which are built into the front panel 3. The keypad 7 is used to enter the desired cooking levels including their sequence, as well as the individual cooking parameters, including the buttons in field 7 corresponding symbols or wear labels. The keypad 9, on the other hand, is a numeric keypad from 0 to 9 and is used to enter the desired amounts of the previously selected in field 7 Cooking parameters.

The following examples are mentioned as cooking parameters: start of cooking, duration and temperature of the individual cooking levels. The following cooking levels can be considered, for example: Cooking in a stream of hot air, browning with a red light emitter, gratinating, keeping warm.

In the front panel 3 there is also a clock 8 with a numeric display, signal lights 10, control lights 6 and an information carrier 4 installed. The clock 8 is part the clock of the microprocessor.

It is also possible to use the microprocessor for acoustic signals to be triggered at the end of the individual cooking stages and / or the cooking program sequence.

The two control lights 6 indicate the status of the program entry, while the signal lights 10 on request the current status of the cooking program sequence Show.

The information carrier 4 is, for example, in the form of a finite one or endless belt or a roller and carries an instruction manual and a collection of cooking recipes. The information carrier 4 can be easily changed to the recipe collection for the respective sales area adapt.

In the event of malfunctions in the cooking program control device only the front panel 3 removed and the relevant, visually marked as defective The plug-in card of the microprocessor, which is modularly constructed from several plug-in cards, has been replaced to become.
