The invention focuses on providing a stir fryer capable of heating and tossing food in order to replicate and deskill the process of Wok cooking. Its capabilities include, but are not limited to, stir frying, steaming, pan frying, deep frying, poaching, boiling, braising, searing, stewing, making soup, smoking and roasting nuts.

Fig 1. illustrates schematic representation of the stir fryer 1 along with all the automation components of it. The stir fryer 1 has a pot 2 into which the ingredients are put to cook a dish. The stir fryer 1 includes a heating means 3 which is placed in proximity to the pot 2 to heat the pot 2. The pot 2 also includes a rotation means 4 which rotates the pot 2 rotate symmetrically or eccentrically about an axis. To regulate speed of rotation of the pot 2, a rotation regulator 5 is provided. The rotation regulator 5 receive a rotational trigger 16 to vary the speed of rotation of the pot 2. It is pertinent to be noted that the varying of the speed of rotation can be according to various steps of the cooking. If a particular step of cooking required a different speed of rotation of the pot, the speed can be varied by providing rotational trigger 16 to the rotation regulator 5. Accordingly, during the complete cooking cycle, multiple times the rotation trigger 5 can be provided to vary speed of rotation as per desired speed of rotation required for each of the cooking step. It is pertinent to be noted that the rotational trigger 5 can be provided through manual means, such a rotor which can be rotated manually by the user to rotate the pot 2. Also, the rotational trigger 5 can be provided through automated means through a microcontroller 15, as it is shown in the current embodiment of Fig. 1.

The stir fryer 1 also has a tilting means 6 which is used to tilt the pot 2. Tilting of the pot 2 can be required during various steps of cooking, such as during placement of the ingredients, and to dish out the cooked dish. Also, during cleaning of the pot 2 also the tilting of the pot 2 shall be required. It is pertinent to be noted that some of the dishes shall require tilting of the pot at a particular gradient to have most effective cooking. The tilting means 6 shall be helpful to change the gradient at requisite angle as per requirement of a dish to be cooked. For some dishes, even the gradient of the pot is further required to be changed during different processing steps. The tilting means 6 comes handy for such tilting of the pot 2 multiple times at short durations during the cooking cycle of a dish.

The tilting means 1 is capable to rotate the pot 2 at a tilt angle up to one hundred and eighty degree from a normal of a base on which the stir fryer 1 is placed. In furtherance, a locking means 7 is also provided with the stir fryer 1, which locks the pot 2 at a particular gradient. In absence of locking, the user would have to hold the pot 2 at a specific gradient, which will increase human effort for holding the pot, and also the user has to keep on checking for the gradient should not change while he is holding the pot 2. Even though, such embodiment is possible to have the tilting means 6 without locking means 6, however, it shall increase human efforts.

The tilting of the pot can be manually carried out. However, to further reduce the human efforts, an automatic actuator is provided which receives and process a tilt trigger 26, and adapted to actuate the tilting means 6. This tilt trigger 26 can be manually provided through electrical interface where a push button or rotor, or any other kind of trigger generating input means can be provided which can be used to provide user input to change the tilt angle of the pot on receiving such user input from the electrical interface. The tilt trigger 26 generation can be further automated which can be generated by the microcontroller 15 directly based on a particular dish to be cooked. Current embodiment, provides the tilt trigger 26 to the tilting means 6 from the microcontroller 15. Such generation of tilt trigger 26 automatically further deskills the whole cooking process.

The stir fryer 1 is further provided with ingredient dispensers 9 which are placed near to the opening of the pot, so that the ingredients from the dispenser can directly and easily dispensed into the cavity of the pot 2. There can be one ingredient dispenser 9 for dispensing only one ingredient such as water or oil. However, the stir fryer 1 can have multiple dispensers to dispense out each of the ingredients which are required to be used while cooking a dish. In case, if only dispenser 9 is provided than all other ingredients have to be manually picked by the user and have to be dispensed into the cavity of the pot 9. To control dispensing of the ingredients, so that the ingredients are dispensed only according to a particular measurement, an ingredient dispense controller 10 is provided which receives a dispense trigger 11 to control dispensing of the ingredients into the pot 2. This dispense trigger 11 can be generated using an electrical interface by pressing a button or rotating a rotor which generates electrical signal in the form of dispense trigger 11. The other way is to generate the dispense trigger 11 automatically by the microcontroller 15, as disclosed in the current embodiment. Complete automation removes human error and further deskill the cooking process.

In one embodiment, the one or more ingredients dispensers 9 are aligned to the pot is such a way that the one or more dispensers 9 are also tilted with the tilt of the pot 9. One way to do so is by having the same tilting means 6 shall be functionally coupled to the pot 2, as well as, the dispensers 9, such that when the pot 2 moves the dispensers also moves. Other way can be to provide a separate tilting mechanism for the dispensers 9 which tilts the dispensers separately. In such scenario, the user can visualize the tilt angle of the pot 2, and further tilt the dispensers 9 with the same angle by using manual tilting mechanism or through semi- automated means using electrical interface for generating tilting signals for actuating tilting mechanism for the dispensers 9. Such tilting of the dispensers 9 can also be fully automated using a separate tilt trigger being generated by the microcontroller 15 which can read about the recent tilt angle of the pot 2 from a local memory unit, and accordingly generate tilting trigger for tilting the dispenser 9, and send such tilt trigger to the tilting mechanism for the dispensers 9.

The stir fryer 1 is further provided with cleaning fluid dispensers 27 which are placed near to the opening of the pot, so that the cleaning fluid from the dispenser 27 can directly and easily dispensed into the cavity of the pot 2. Where there is only one cleaning fluid to be dispensed, in such scenario only one cleaning fluid dispenser 27 in required. However, in cases, where water, steam, and liquid soap are dispensed during a cleaning operation of the pot, at least 3 cleaning fluid dispensers 27 are required. Similarly, for different cleaning operations different cleaning fluids are required, and accordingly number of cleaning fluid dispensers may vary. In some scenario, there can be powdered soap also dispensed, and in such scenario, another type of dispensers can be used which can dispense powder. To control dispensing of the cleaning fluids, so that the cleaning fluids are dispensed only according to a particular measurement or with a particular pressure, or both, a cleaning dispense controller 28 is provided which receives a cleaning trigger 29 to control at least one of amount of dispensing of the cleaning fluid or pressure of dispensing of the cleaning fluid from the one of more cleaning fluid dispensers 27, or combination thereof. This cleaning trigger 29 can be generated using an electrical interface by pressing a button or rotating a rotor which generates electrical signal in the form of cleaning trigger 29. The other way is to generate the cleaning trigger 29 automatically by the microcontroller 15, as disclosed in the current embodiment. Complete automation removes human error while cleaning the pot. In one embodiment, the one or more cleaning fluid dispensers27 are aligned to the pot is such a way that the one or more dispensers 27 are also tilted with the tilt of the pot 2. One way to do so is by having the same tilting means 6 that shall be functionally coupled to the pot 2, as well as, the dispensers 27, such that when the pot 2 moves the dispensers also moves. Other way can be to provide a separate tilting mechanism for the dispensers 27 which tilts the dispensers separately. In such scenario, the user can visualize the tilt angle of the pot 2, and further tilt the dispensers 27 with the same angle by using manual tilting mechanism or through semi-automated means using electrical interface for generating tilting signals for actuating tilting mechanism for the dispensers 27. Such tilting of the dispensers 27 can also be fully automated using a separate tilt trigger being generated by the microcontroller 15 which can read about the recent tilt angle of the pot 2 from a local memory unit, and accordingly generate tilting trigger for tilting the dispenser 27, and send such tilt trigger to the tilting mechanism for the dispensers 27.

In one embodiment, same dispensers 9, 27 are used for dispensing cleaning fluids, as well as, ingredients. Cleaning liquid is enabled to be dispensed at various pressures to remove the stains effectively. Where the dispensing system is same of liquid ingredients and cleaning liquids, different pressures can be applied for different purposes. For example, oil/ghee/butter dispensing can happen at lower pressure from the same dispensers 9, 27 whereas cleaning liquid can be dispensed at higher pressure.

In furtherance, it is significant to mention that rotation of the pot 2 while cleaning is being carried out, substantially enhance the cleaning operation. Hence, the pot 2 shall be rotated, either manually, or through automated means using microcontroller where cleaning trigger also triggers rotational regulator to regulate rotational means too. A combination of rotation of the pot 2, and the dispensing of cleaning fluids allows cleaning liquid to touch the entire cooking surface of the wok. Further, dispensing of the fluids at a pressure along with rotation of the pot 2, further enhances the cleaning operation.

The cleaning fluid dispensers can also be used to dispense steam at higher temperatures to assist in deep cleaning of wok surface.

In furtherance, the pot can be provided with a lid, so as to control the spillage of contents while cleaning.

The stir fryer 1 also has one or more tossing or stirring arrangement 12 which are coupled to the pot 9, These tossing or stirring arrangements 12 can be replaced with specific tossing or stirring arrangements for tossing specific dishes. These tossing or stirring arrangements 12 can either be placed inside the cavity of the pot 2, so that when the pot 2 rotates the tossing or stirring arrangements are also rotated and due to the rotation, the ingredients are tossed by the tossing or stirring arrangement. One possible way is to fix the tossing or stirring arrangements to the wall of the pot 2, Another way is to place the tossing or stirring arrangement 12 in proximity to the cavity of the pot 2 and a head of the tossing or stirring arrangement 12 is adapted to be placed inside the cavity of the pot 2 to toss the ingredients while carrying out a cooking operation whenever is required. In this scenario, the tossing or stirring arrangement can be attached to a part of a frame of the stir fryer 1, or ever it can be attached to an external surface of the stir fryer, and whenever a cooking step requires tossing, the head of the tossing or stirring arrangement 12 can be lowered into the pot, almost to the base of the cavity of the pot 2, so that the tossing can be carried out. It is pertinent to be noted that in one embodiment, further movement of the tossing or stirring arrangement 12 after lowering down may not be required, and the tossing happens due to relative motion between the pot 2 and the tossing or stirring arrangement 12. In another embodiment, the tossing or stirring arrangement 12 is also moved in a predefined motion, so that to further make tossing operation more efficient. In such scenario, to control movement of tossing or stirring arrangement, a tossing controller 13 is provided, which receives tossing trigger 14 to control movement of the tossing or stirring arrangement 12. This tossing controller 13 also helps in controlling movement of the head of the tossing or stirring arrangement 12 for moving in and out of the pot 2.

In one embodiment, the tossing or stirring arrangement 12 also tilts along with the tilting of the pot 9. This embodiment is helpful to keep the tossing or stirring arrangement 12 to be always aligned to the opening of the pot 2. One way to do so is by having the same tilting means 6 shall be functionally coupled to the pot 2, as well asthe tossing or stirring arrangement 12, such that when the pot 2 moves the tossing or stirring arrangement 12 also moves. Other way can be to provide a separate tilting mechanism for the tossing or stirring arrangement 12 which tilts the tossing or stirring arrangement 12 separately. In such scenario, the user can visualize the tilt angle of the pot 2, and further tilt the tossing or stirring arrangement 12 with the same angle by using manual tilting mechanism or through semi -automated means using electrical interface for generating tilting signals for actuating tilting mechanism for the tossing or stirring arrangement 12. Such tilting of the tossing or stirring arrangement 12 can also be fully automated using a separate tilt trigger being generated by the microcontroller 15 which can read about the recent tilt angle of the pot 2 from a local memory unit, and accordingly generate tilting trigger for tilting the tossing or stirring arrangement 12and send such tilt trigger to the tilting mechanism for the tossing or stirring arrangement 12. The heating means 3 is further coupled to a heat regulator 20 which receives a heating trigger 17 to regulate the heating medium 3 by varying heating quantum or switch on or switch off of the heating medium 3. This heating trigger 17 can be generated using an electrical interface by pressing a button or rotating a rotor which generates electrical signal in the form of heating trigger 17. The other way is to generate the heating trigger 17 automatically by the microcontroller 15, as disclosed in the current embodiment. Complete automation removes human error and deskills the cooking process. For generating various triggers to control functioning of the stir fryer 1, the microcontroller 15 is provided with the stir fryer 1. The microcontroller 15 generates the tilt trigger 26, a rotational trigger 16, the dispense trigger 11, the tossing trigger 14, a cleaning trigger 29, and a heat trigger 17 to be sent further to the automatic actuator 8, the rotation regulator 5, the dispense controller 10, the tossing controller 13, the heat regulator 20 and the heating means 3 respectively. These triggers are generated based on various inputs received by the microcontroller 15 from an input unit 18, and a temperature data 31 from a temperature sensor 30. The input unit 18 receives a selection input 19 to select a recipe from a selection of recipesand a portion input 21 relating to a quantity of recipe chosen to be cooked during a cooking operation. The microcontroller 15 receives and processes the portion input 21, and the selection input 19 and generates at least the tilt trigger 26, the rotational trigger 16, the dispense trigger 11, the tossing trigger 14, the cleaning trigger 29 and the heat trigger 17. It is pertinent to be noted that in scenario where complete automation for rotation of the pot 2 is not required the rotational trigger 16 need not be generated. Similarly, where the automation of dispensing of ingredients is not required, the dispense trigger 11 need not be generated by the microcontroller 15. In same way, where movement of tossing or stirring arrangement 12 is not required, the tossing trigger 14 is not generated. And, where heating of the pot 2 is not automate, the heat trigger 17 is not generated. Similarly, where tilting of the pot 2 is not required to be automated the tilt trigger 26 is not generated. And, where cleaning of the pot 2 is not required automatically, and is carried out manually or in semi-automatically, such generation of the cleaning trigger 29 is required by the microcontroller 29.

The temperature sensor 30 measures temperature at a given point of time and generates a temperature data 31, and sends the temperature data 31 to the microcontroller. The temperature sensor 2 is placed in proximity or onto the external surface of the pot. The temperature sensor 30 can also be placed in proximity to or on to the inner surface of the pot 2. This temperature data 31 is further sent to the microcontroller 15 which processes it to further generate the heat trigger 17 to control the heating means 3 for maintaining a required temperature at a given point of time when a cooking cycle for a particular dish is being carried out for a given portion of the dish. The arrangement enables the change in temperature of the pot rather quickly. This is to modulate the heat transfer even along the process of cooking a single portion. For example, a dish may take 400 seconds to be fully made with several ingredients to be dispensed at different instants in that 400 seconds. Now, temperature can be controlled as desired at different timestamps for various ingredients to be cooked to perfection in the given preparation time of the dish. The processing of temperature data 31 is significant at beginning of the cooking process of the dish, as the pot 2 may already be at a temperature level after cooking of preceding dish, and hence further management of the heating of the pot 2 is required to optimize the temperature of the pot 2 to a desired level to start cooking a dish. Thereafter, management of the temperature is required during various steps of cooking. It is pertinent to be noted that while beginning of a cooking operation, temperature data 31 is processed along with selection input 19 and portion input 21 to reach a desired level of temperature of pot to start cooking, however at later stages the temperature data 31 is processed alone by the microcontroller 15 at regular intervals of time, so as to control temperature of the pot 2 as desired for each steps of cooking of the dish. In furtherance, in one embodiment, the microcontroller 15 can only receive the selection input 19 to select a recipe and each recipe is only linked to a predefined portion to be selected, and hence the portion input 21 is not received.

When microcontroller 15 receives a selection of the recipe, the microcontroller 15 generates triggers in predefined fashion as per the rules stored in a local memory of the stir fryer 1. When a recipe selection is received, the microcontroller 15 extracts the specific cooking rules from the local memory and process the rules to generate triggers, so as to control various functional components of the stir fryer 1. In case, if some of the functional components are not automated or linked to microcontroller 15, the microcontroller 15 generates instructions to be displayed on a display (not shown) of the stir fryer, so that the user can carry out such functions on the stir fryer 1 manually. In one embodiment, the instructions are generated along with the ingredient’s images for easy reference and quick reception by the user.

In one specific embodiment, where the stir fryer 1 is enabled to only cook one dish only, even the selection input 19 is not required, and as soon the stir fryer 1 is switched on, the microcontroller 15 is activated to cook that specific dish only, and the microcontroller 15 fetched the only rule to cook that specific dish, and process those rules to generate various triggers and/or instructions for cooking the dish. Fig. 2 shows a side view of one embodiment of the stir fryer 1. The stir fryer 1 has a pot 2 having a cavity (not shown). The stir fryer 1 has a lever, as tilting means 6, to tilt the pot 2. The lever 6 is physically attached to the pot 2, and can be rotated to rotate the stir fryer 1. The stir fryer 1 is further provided with a locking means 7. The locking means 7 are achieved through a groove arrangement and an extension of the lever. Various grooves are provided at different tilt angles of the pot 2. To lock the pot 2 at a particular tilt angle, the extension of the lever is engaged into the groove for that particular tilt angle. Fig. 2 shows the pot 2 to be at a first position 22 having the tilt angle of zero degree with respect to base of the stir fryer 1. The stir fryer 1 also has a couple of dispensers 9 aligned to the pot 2. The dispensers 9 can be at two position, in engaged position 24 and disengaged position. In engaged position 24, the dispensers 9 are aligned to the opening of the pot 2, so that the dispensed items can directly move into the cavity of the pot 2. In disengaged position 24, as shown in Fig. 3, mouths of the dispensers are pulled up, so that easy access to inside of the cavity can be provided. The dispensers 9 are physically aligned to the pot 2 such that the dispensers are also moved when the pot is rotated. Such movement of the dispensers can be seen from Fig 3, where the pot is at a second tilt position 23.

Figs 5-7, shows the stir fryer 1 with different types of tossing or stirring arrangements 12a, 12b, 12c for cooking different types of dishes. Fig. 5 shows the stir fryer 1 with the tossing arrangement 12a for cooking rice. Fig. 6 shows the stir fryer 1 with the tossing arrangement 12b for cooking noodles. AndFig. 7 shows the stir fryer 1 with the stirring arrangement 12c for cooking soups. The tossing or stirring arrangements 12a, 12b, 12c are replaceable attached to a side wall of the cavity of the pot 2. The figures also show dispensers 9, the tilting means 6, and the locking means 7 to provide a better visibility of these elements. In one embodiment, the pot is provided with a lid. The lid when placed airtight on the pot, will be able to control pressure inside the pot. In furtherance, lid also prevents spillage of ingredients while in the cooking process even without additional pressure application. With a combination of rotation of pot, tilting of pot, and pressure/temperature variation inside the work, several dishes are cooked to perfection.
