• the device according to the invention integrates the most modern technology in the user friendly technology.
• Control of operation is manual and user selects operation method with rotating the button.
• Button (2) is set on the casing and works in manual operation as a classical button.
• the button can also be lifted from the basic position.
• Image 6 shows implementation, when the button is integrated in the universal removable handle (19), which is a standard component of kitchen furniture. Many times we cook without the lid and here we can save the problem of control so that we set the button (21) on the handle.
• the container (23) in this case does not have its own handles and the handle has a flexible part (22) that hugs the rim of the container. With the button (20), part (22) is released and handle can be removed.
• the operation method of the button as a device for control and fixing will be described below.
• illuminated symbol (24) that shows the user operating method.
• Image 7 shows implementation example of the hotplate control, where there is a button (26), which was before in the bed (28), placed on the handle (27).
• Control logic of the stove with transfer of the button to the handle changes operating method and automatically starts automatic cooking process. With setting the button to the position (28), the operation also returns to the manual operating method. Connection between the position (28) and the device for cooking and the button is wireless. It is realized in this implementation example with radio waves and specific protocols.
• Image 8 shows similar solution as image 7, except that this solution is more useful for classical containers (30) that already have its own handles and lid, but have to be opened during operation, for example with the container for cooking milk or typically with the container for cooking spaghetti.
• Button (31) is set on the minimal support (29), so it does not disturb the user.
• Image 9 explains components of the control button (32) - devices according to the invention.
• the device has:
• Powering of the module is done by the power module (36). Some possible supply methods are explained in details below.
• Sensor module needs special sensors that are usually temperature sensors, sound and pressure sensors and also any sensor that is necessary for quality capturing of data.
• the fixing module (37) is inserted in the base for fixing the button (32). Operation is later on explained in details.
• Image 10 shows implementation, where modules are optionally organized in special casings (38) and (39) and set in groups. All modules can be on one circuit, individually or in optional combinations. Mutual connecting can be done with a connector or wirelessly.
• Image 11 shows the method of fixing the button - device (40) on the lid (43).
• the magnet (41) can be in the casing of the device or placed with magnets (42) on/under the lid. Magnet attraction can also be realized with nonmagnetic metal.
• the magnet is on the base and on the other side is the part that is attracted by the magnet of the metal (iron) part of specific size and shape.
• magnet is used in the casing that is set on the iron base.
• Image 12 shows other classically known fixing method.
• Mechanical connection with the screw (44) is known method of fixing handles on the lid.
• Plastic part that has wedges for other separating part on the handle can be fixed on the lid (43) with the screw.
• Such possible solutions are known and are not the subject of the invention.
• Image 13 shows the fixing of the button that is fixed on the lid with a special rubber nipple designed so it contains channel (45). With finger- press on this channel, the air is released from the nipple. With failure, rubber form creates specific force, because of the pressure, which creates the force after press failure that holds the button on the lid. These methods are not the only option. In this case the electronic is protected from the water.
• Image 14 shows similar implementation where cylindrically shaped silicon rubber (46) holds the magnet and also protects system from the water. Special feature is also the second metal part, which also can be dressed in silicon (47) that we set on the bottom side of the lid. This is especially useful with glass lids or other nonmagnetic materials.
• the battery can also be the basic method of supply. Battery has to enable at least 6 months of operation. Because batteries are very user unfriendly, implementation examples show some methods of operating without batteries.
• Image 15 shows the button that uses condenser or digital energy saver instead of battery for storing energy in power module.
• Charging energy storage is in this case done with the help of electromagnetic inductive charging trough spools (49).
• Spools are located on the button and in the casing. With the help of electronic circuit, the spool creates electromagnetic field on the stove, which induces energy in the spool in the button, which is then prepared for storing trough electronic circuit.
• ferrite cores we can use ferrite cores, but we can also use spool for transfer of information between modules in different implementation examples.
• Image 16 shows example of button implementation, when information and powering between button supports and button is done with a connector (50).
• Image 17 shows interesting powering method with the help of peltier element. Because the lid of the container is located in the area, where we have enough heat energy, peltier element (51), which converts heat energy into electric energy, is used for powering module and charging of energy storage. Image 18 shows similar method as image 17, we can charge storage with photovoltaic cells (52) on the button with adjusting different voltage levels, which is not the subject of the invention. During the use it is very important for the user to see the position in which he/she placed the button - device.
• Image 19 explains the interaction between the stove and the user, as a confirmation of its wish.
• the user sees the position in which the button is set with the mark on the button and position rotated to one of the symbols.
• this method of interaction can be retained.
• the method for selecting function is the subject of the invention and represents implementation of the button position selector in the relationship with the ring for placing.
• the shape of the slider (55) is that it lies in the channel (56) with the tab, which is on the cylindrical form of the button. This can, with rotating of the button or rotating cylindrical part around the button, determines desired position for determining desired control method.
• Image 20 shows implementation example where the positions are determined with the help of potentiometer.
• Potentiometer (58) is fixed on the electronic panel. In the middle of the potentiometer is the part (59). With rotating around common axis user can select specific control method. In specific implementation examples we need both control methods. The example is to determine the type of cooking with symbol, such as roasting, frying and cooking milk, with the second choice we determine continuous temperature or other, for example temperature of oil for frying. The method of interactive display will be explained later.
• Image 21 shows very interesting selection method without contact and so very safe managing with magnets. Reed relays (61 ) are turned on and off with the help of the magnet (60). Presented are only some possible combinations of use.
• Image 22 shows the most ordinary method, when the user determined selected function with the help of keys on the button.
• One of the implementation examples has three keys.
• the key (64) is for confirming operation of the key (63) and (62), with plus + and minus - we can digitally change settings.
• Image 23 shows special examples of button implementation according to the invention that is used on the water heater (65).
• the invention saved the problem of energy control in the water heater, which in practice mostly rotates for 360 degrees and can be removed from the base.
• the electronic into the base, which has built-in a couple of reed relays on the areas (67) from A to G.
• Temperature sensor (71) can be mounted directly on the handle or as a temperature sensor (70) directly senses in the container. We can place it so that it directly measures temperature of oil or milk. Especially interesting is the case, when the sensor is placed directly on the meat, where it also senses the temperature in the depth of the meat. Sensor can be wired or wirelessly connected with the handle and the stove.
• Image 25 shows implementation example of a button - device according to the invention for examples of circulation pump control with centrifugal turbine (75).
• Sound sensor is primarily used as a sensor (73), also possible are temperature or pressure sensor.
• the sensor part (74) is in this case wirelessly connected with the control button (76), which is also wirelessly connected with the pump.
• Image 26 shows possible connections with connectors and with contacts (78). With placing on the handle, control button (77) connects the contact (78) with the sensors (79) and (80). Information about the position that user selected is very important to the user.
• Image 27 shows one of possible methods with illumination of the symbols on the selector (83).
• LED diode (81) is placed on the electronic panel, which lights on the part (82) that leads the light as a beam to the symbol (84). Light moves trough the symbols with rotating the button (85) in relation to the part (83).
• Device implementation according to the invention enables user friendly method of cooking process control and various quality methods of cooking, which are not know to the stoves today.
• Wireless connection between the button and the stove enables very accurate device control, because sensors can be placed on the lid or on the lid handle. Together with temperature sensors in the stove, there is also possibility of dynamic control of heat flows in different points. Because the sensors can also be sound and pressure sensors, it is possible accurately determine boiling and other cooking processes. Intensity of the boiling is very important with cooking. When heating water in the container, we sense sound signal together with formation of the bubbles. We can differentiate boiling state with microphone and digital sound analysis.
• Determining cooking state does not depend only on the temperature, physical state is also determined with other different sensors.
• the device for energy control enables level data capturing with its sensor in the form of a button and, where this is the most necessary, on the lid and the handle.
• the button can be on the lid or on the cooking device.
