DETAILED DESCRIPTIONS OF PREFERRED EMBODIMENTS :

Now referring to figure 1 the Microwave Android Integrated Device (MAID) Oven is a microwave oven that has smartness integrated to it. It has an android powered panel compared to ordinary user consoles. MAID can sync recipes from the internet and cook dishes automatically once the ingredients required are provided. MAID is unique and novel in its concept as virtually unlimited number of dishes can be cooked automatically. The user need not know any recipes or how to operate an oven.

Another major feature of MAID is that it can stream cookery videos from the internet so that the user can cook a dish while watching the video. This helps in making dishes that are usually demonstrated on TV, which otherwise is a hard task.

Ingredients search is another option by which the user clicks on the name of an ingredient and he is shown an image of the same. This helps in identifying ingredients. The user also has the provision for entering their own recipes which will be stored in MAID and can be used for cooking later also.

The figure 2 shows how a MAID oven communicates with the internet. There is virtually unlimited number of recipes stored in the internet and MAID can sync these recipes with its local storage when it is connected to the internet. Recipes are categorized according to their types - desserts, pizzas, rotis, cakes, etc. The MAID connects to the internet and updates its recipe database with the new recipes in the internet. It also retrieves video list and stores in its database. Required videos are buffered from the internet and played.

The figure 3 explains how the touch console in the MAID process data internally. When internet connection is available, the microprocessor inside the MAID syncs with the recipe database and updates the local storage with new recipes. Virtually, unlimited number of recipes can be stored in this local storage and hence, it offers unlimited dishes for automatic cooking.

The microprocessor is connected to the LCD touch panel which displays ingredients list and each step of cooking. All the available recipes and their details are listed in this touch panel according to the categories. The touch panel also takes user input and sends it to the microprocessor. The microprocessor fetches the recipe according to the user's choice only.

There is a speaker that reads out the instructions step by step. This voice assisted cooking is easier and more efficient.

If a step in the recipe is an oven triggering signal, that is, an instruction to switch on the microwave/grill/fan for a given time period, then the microprocessor sends this instruction to the oven relays that perform the required function.

The figure 4 shows an electronic Circuitry used for controlling the device.

Main Circuit board consists of components which are connected to Microprocessor which is the brain of MAID. The Various sections is listed below as shown below;

OPERATING SYSTEM OF MICROPROCESSOR

Android Operating Systems provides GUI for the MAID. It receives the input from the user and processes it and passes the corresponding actions to Microcontroller using AOA. ANDROID Operating System works as the Embedded Operating System for the MAID.

Touch Screen takes the input from user and passes the data to Microprocessor in which it processes the data with the help of Android Operating System and outputs the corresponding data to the speaker or Microcontroller. On the basis of data received from Microprocessor Microcontroller turns ON/OFF the GRILL, MICROWAVE, CONVECTION, FAN, MOTOR Relays.

WORKING

1. The user selects corresponding dish from the main menu in Touch Screen LCD Display and device checks whether dish is available or not in the local storage.

2. In case dish is not available in data of device, the device downloads the recipe list as well as cooking methods from the internet from a common recipe portal website and shows the user how to cook along with voice assist.

3. The user performs the corresponding actions prescribed by the MAID and closes the door then the oven self adjust the temperature and time for cooking that dish.

4. The Android Operating Systems provides GUI for the MAID It receives the input from the user and processes it and passes the corresponding actions to Microcontroller using AOA. The ANDROID Operating System works as the Embedded Operating System for the MAID.

5. The Touch Screen takes the input from user and passes the data to Microprocessor in which it processes the data with the help of Android Operating System and outputs the corresponding data to the speaker or Microcontroller.

6. On the basis of data received from Microprocessor, Microcontroller turns ON/OFF the GRILL, MICROWAVE, CONVECTION, FAN, MOTOR Relays.

7. The microwave device of invention can be controlled over an android phone via Bluetooth.

Ultimately, the present invention is a microwave oven controlled by a touch screen console which is powered by Android operating system enabling the device to connect to internet and perform the operations based on commands sent via internet.

THE SUMMERY OF INVENTION

Microwave Android Integrated Device (MAID) Oven can directly communicate with internet through wifi modem as it involves an operating system which controls the oven and no special section is needed for receiving data and perform cooking Operations. No external device as well as no voltage level converters is required for MAID

MAID operates on Touch Screen LCD Panel which is a single section and various operations like cooking selecting recipe etc are done based on various software application icons which appears on Touch Screen LCD Panel and user touch actions on its touch screen with his//her fingers.

MAID automatically syncs all recipes from webserver to its memory whenever it connects to internet This Unique capability of MAID enables to store lakhs of recipes to its memory and user need not worry about selecting particular recipe from internet and bookmark it or delete it. And user does not need internet after once it connects and sync all data from webserver. That is user doesn't need internet whole time to operate MAID.

MAID is not controlled by internet, it is operated by ANDROID Operating system.
