Description

The present invention relates to a method for the treatment and preparation of food in a cooking device.

Furthermore, the present invention relates to a control panel for a cooking appliance and a cooking appliance, especially a steam cooker itself.

Processes for the treatment and preparation of food have been in use for many years known a cooking process by means of cooking devices, in which several parameters for implementation of the cooking process can be determined. Conventionally, one of the cooking appliances offered modes of operation preselected depending on the food to be cooked. such Operating modes are, for example, hot air, steaming, roasting, regeneration, etc.

Based on the preselected operating mode, parameters are preselected corresponds to this operating mode. In addition to the selected operating mode, there must be more Parameters are entered by the person operating the cooking device, for example Temperature, humidity, etc., these values being independent of each other in consecutive steps must be entered.

A food cooking process usually involves one or more program steps such as warming up, steaming, roasting and then gratinating, each individual program step by the operator by entering the corresponding parameters must be determined.

The input is conventionally made, for example, by a line structure The display field shows the corresponding parameters in several lines, and then each parameter is controlled, for example by means of a rotary knob, and when reached the correct value of the parameters by pressing a specific confirmation button is selected for this program step.

The present invention has for its object a method for treatment and Specify food preparation in a cooking device that is extremely simple Way the parameters of the cooking process can be selected.

Furthermore, the The present invention has for its object to provide a cooking device in which the above mentioned goals can also be achieved.

According to the present invention, the input device is used to mark a point in one at least two-dimensional map of the operator of the cooking device controlled, in which at least two cooking parameters are defined, and the set Point implemented as part of the cooking process in the cooking program.

This advantageously ensures that the parameter setting by the operator, usually the cook, not just easy but also quick can. In addition, the operational safety and the overview are significantly increased. As a result, input errors are avoided more.

The temperature or to be achieved in the cooking space can preferably be used as cooking parameters Moisture, the speed of the fan wheel of the cooking device, the degree of browning of the food and / or the core temperature of the food is selected.

To the operator (cook) and especially unskilled or only semi-skilled Fields are intended to help people choose a parameter predefined for various cooking processes and are activated when activated indicated by the input device preferably in the map. These predefined ones and corresponding graphically or photographically indicated fields are also from Expertly referred to as the "language of cooking".

Every point of the map can be reached with particular advantage, so that every possible point Combination of pre-selected cooking parameters is adjustable. It can be, for example deal with the temperature and humidity in the cooking space, which makes the cooking space climate adjustable is. Alternatively, depending on the treatment step, other parameters such as cooking time, Core temperature, fan wheel speed, degree of browning of the food in the map be taken as a basis and selected by the operator. This allows the Operator to select the full range of possible cooking parameters, where extreme settings are also possible.

Treating and preparing food is known for this reason particularly stressful because the operating personnel perform the most varied of tasks has to meet in every type of kitchen, whether commercial kitchen or canteen or star restaurant. The easier and safer a cooking process can be set, the better. The food to be cooked should also be protected from overcooking in order to ensure its optimal consumption quality to reach.

It is therefore particularly advantageous to control the program point in the Map using a multi-dimensional input device, such as a rocker switch Joystick, a computer mouse or a touchpad, the latter for example from one Known laptop.
