Description

Identification feature controlled heating method

Background of the Invention: a) Field of the Invention:

The invention relates to a heating method controlled by the recognition of an identification feature, in particular the way that all parameters necessary for proper heating are read and recognized.

b) Description of the current state of the art:

It is part of the service offered by many supermarkets that ready meals, which have just been purchased by the customer, are warmed up on the spot with the help of a microwave oven and thus made edible. The necessary settings on the microwave oven are made by the consumer or the store staff by hand. This procedure has the following disadvantages: 1. If not heated long enough, it is difficult to find the right reheating time.

2. Heating too long will waste time and energy and may even render the dish inedible.

3. Visually impaired, illiterate or children are not able to read the instructions for use and to operate the oven.

Summary of the invention:

The main object of the invention is a method for heating a

Food, whereby by reading an identification feature that contains parameters such as heating time and temperature controls the device used for heating and thus not only simplifies the operation but also made safer,

The device used for heating has for this purpose a sensor that reads the information stored in the identification feature and software for their interpretation.

Detailed description of the preferred embodiment

1 and 2, it will be seen that the object to be heated (1) belongs to the invention and is provided with an identification feature (2) containing all the parameters necessary for heating and the heating device (3). which in the example is a microwave oven (31) with a display (311) and control buttons (312). It also has a sensor (32) which reads the information of the identification feature (2). These are then used to control

Temperature and heating time used. In the present example, a one- or a two-dimensional barcode is used, which is why the sensor (32) is designed as a barcode scanner. In the example he is attached to the heater (3).

The sensor (32) reads the information contained in the identification feature (2) of the object to be heated (1), which is used after evaluation by the built-in program to control temperature and heating time fully automatically. The heating of ready meals in this way not only leads to a considerable saving of time, simplifies the operation and safety against incorrect operation, but also reduces the risk of improper heating of spoiled ready meals. It is suitable for a wide range of applications, such as Home, supermarket, charitable institutions, company canteens and more.

The described automatic heating of prepared meals is not only simple, convenient and reliable, but also versatile, because the built-in display (311) allows to intervene manually in the heating process via the control buttons (312).

As can be seen from Fig. 3 under assistance of Fig. 4, the method according to the invention comprises the following steps:

Step 1: Attaching the identification feature (2) on the object to be heated (1)

Step 2: The user holds the object to be heated (1) in front of it

Heating device (3), that the identification feature (2) in the detection range of the sensor (32).

Step 3: The sensor (32) converts the information of the identification feature (2) into digital information.

Step 4: Calculate the parameters for the heating process and display on the display (311).

Step 5: After checking the data by the user Insert the object to be heated (1) into the heater (1) and press the start button to start heating or the cancel button to cancel and return to step 2. The stop button may also be pressed to stop the heating process, after which the process may be continued by pressing the start button.

Step 6: An already running heating process can be stopped at any time by pressing the Cancel button.

Step 7: The end of the heating process is indicated by an acoustic signal and on the display.

Step 8: When the start button is pressed again, the heating process is repeated with the same parameters.

Step 9: The parameters contained in the identification feature (2) can describe both a one- and a multi-stage heating process with different lengths of time and different temperatures.

Fig. 5 shows a further embodiment of the invention. It differs from the one described above in that the sensor (32) is not fixedly installed in the heater (3) but connected to it by a cable so that it can be held by the operator via the identification feature (2) , This makes the operation easier for certain people.
