Description

The invention relates to a household appliance for roasting, baking and cooking gears with a microwave heating device for solo operation and combination operation with thermal heaters.

Frying, baking or cooking food using microwave energy can lead to fluctuations in the degree of cooking, which affects the overall result of the cooking process are qualitatively detrimental.

This taste, which can be traced back to different ways of cooking the food influence is due to the fact that the absorption coefficient of the food Differentiate pieces strongly, for example by different water finding and / or fat growth can be caused.

For these reasons, sensor-controlled automatic cookers have become known optimal control through temperature, humidity and / or conductance measurements seek to bring about the cooking process. But since the microwave heating from Pieces of food in a much shorter time than that at tra traditional heating process takes place, certain areas can be cooked Tem  accept temperatures that do not correspond to the average degree of cooking. It can not be excluded by temperature probes that the microwave energy is switched off too soon or too late.

To remedy this deficiency, there are various cookers with microwave heating that make use of micro-computing technology.

The necessary control information for the microcomputer that the microcomputer for Control or regulation of cooking time, cooking temperature, power level entered must be, is usually via key or switch fields, Programmkar ten or other recording media realized. The cooking programs that can be called up in this way are described, for example, in US Pat. No. 4,317,976.

A programmable microwave oven with respect to the heating conditions is exemplified as disclosed in US-PS 40 11 428. Currently working on the microwave oven The heating or cooking program can partly be shown on a display part be followed.

DE-AS 11 97 996 is a device for electric cooking, pro time program controlled, known, which largely automates the cooking is given.

Have the automated cooking processes that have become known in the prior art either the disadvantage that the user enters too many details of the control data have to be given, which is cumbersome to take from a cookbook software are; or the housewife uses an input medium, for example a keyboard, a fully automatic, with no subjective influence on the cooking process is possible and therefore a standard dish, without a personal touch according to the housewife enart, as the end result is offered to the consumer.

The object of the invention is therefore a simple assignment various ner microwave heating power as a solo power or in combination with others specify electrical heating power so that the housewife next to automated loading alternatively, modes of operation can work semi-automatically.  

The arrangement according to the invention for solving this problem is characterized records that a heating process that controls the cooking process semi-automatically stages and / or temperature value stages coupled dispenser is arranged, the the microwave heating output related to the total cooking time in constant or before assigns programmed performance / time profiles.

Advantageous embodiments of the invention are contained in the subclaims.

An embodiment according to the invention is in the following with reference to the drawing described in more detail.

It shows:

Fig. 1 is a built-in cooker front with an integrated microwave heating according to the prior art,

FIG. 2 is a control panel cutout for microwave energy operation with Do sierwähler,

Fig. 3 shows a cooking chamber with switched top / bottom heat,

Fig. 4 shows a cooking chamber in the hot air operation,

Fig. 5 shows a cooking chamber in the infrared-large area grill operation,

Fig. 6 shows a cooking chamber in a convection-grill mode,

Fig. 7 shows a cooking chamber in the microwave single mode,

Fig. 8 shows a cooking space in the microwave plus grill mode and

Fig. 9 shows a cooking space in microwaves plus top / bottom heat operation.

According to Fig. 1 is a built-in cooker front side according to the prior art provides Darge.

A built-in stove 1 with integrated microwave heating, which shows a control panel 2 and a cooking space 3 with a food 4 can be seen in FIG. 1 ent. The control elements of the control panel 2 correspond to the state of the art. The input for the desired microwave power is done, as can be seen from the control panel 2 , via a button set for four microwave power levels, the coupling of the power level with a clock module also allowing the cooking time to be set. The exposure time to be set for the selected microwave power level corresponds to the specification by cookbook software or the experience of the housewife.

Referring to FIG. 2 is a control panel-neck 5, consisting of a microwave power levels selection 7 and a dose dial 8 illustrates from a Automatikan optionally 6 Darge.

With the help of the dosing selector 8 , the housewife can, in contrast to the fully automatic system, influence the cooking process by entering personal experience or accepted cookbook software. This form of semi-automatic control of the cooking process enables the dosing selector 8 , the dosing selector assigning the microwaves heating output as a solo output or in combination with other electrical heating outputs. This happens depending on the total cooking time in constant or preprogrammed service sequences. For example, in addition to entering the total cooking time in microwave solo mode, a preferred microwave power level can be entered. The dosing selector 8 realizes, based on the total cooking time, a constant basic power duration of the preferred microwave power level. This power level (at least in 60%) of the total cooking time affects the food to be cooked. The dosing selector 8 switches on a second microwave power level for a remaining cooking time (at most 40%) of the total cooking time. The preferred power level remains.

The dosing selector can pre-program 8 preferred microwave power levels with various heating functions. The metering selector 8 for microwave heating power can be coupled with the oven functions top / bottom heat, infrared large-area grill, hot air and circulating air.

In a preferred arrangement, the metering selector can assume 4 metering positions, corresponding to the usually 4 microwave power positions.

All in all, for the user, this results in easily noticeable and simple semi-automatic controls to be operated.

FIGS. 3, 4, 5, 6, 7, 8 and 9 indicate the ver through the dose dial knüpfbaren various heating functions.

FIG. 3 symbolizes the devices of an upper heat 9 and a lower heat 10 acting in the cooking space 3 , while FIG. 4 shows a hot air mode of operation 11 for the cooking space 3 .

Fig. 5 symbolizes the application of the top heat 9 , realized by an infrared large area grill, in the cooking space 3 ; and Fig. 6 is an air-circulating operating mode is 12 for the cooking chamber 3. The circulating air mode 12 saves impaling and rotating movements of the food 4 . The combined with a convection system infrared large-area grill mode of operation allows uniform grilling on all sides without turning and turning since the heat generated by the top heat 9 is circulated by a fan.

Referring to FIG. 7, the oven heating is alisiert solely by microwave energy re. The cooking space 3 is energized via a microwave energy coupling device 13 ; while in FIG. 8 as microwave energy, the heat upper 9, by an infrared grill, is involved in the cooking process. According to FIG. 9, microwave energy is fed into the cooking space 3 via the coupling point 13 and at the same time top and bottom heat 9 , 10 .

This combination, as well as the operating modes marked according to FIGS. 7 and 8 for a cooking space, can advantageously be selected by a dosing selector 8 .
