In some other embodiment, the input/output commands may be given using an electronic device (Eg. a phone) held by the user utilizing a program product (developed for controlling the functionalities of the cooking system 100) installed in the user's electronic device.

[0050] Further as seen, the side walls 104a, 104b of the housing 102 may include one or more ventilation arrangements 104c (E.g. fans) that may assist in venting out hot air, steam, gases, fumes, etc. from the cooking system 100 during its operation. Further, the ventilation arrangement 104c may be operated to even cook certain food/meals using the supplied heat and air from the ventilation arrangements 104c that can circulate around the food just like any conventional air fryer.

[0051] Referring to FIGS. 1-4 and 9-10, the cooking system 100 includes at least a first cooking pot 106, and a second cooking pot 107. The cooking pots 106,107 are essentially made identical in shape to serve the purpose of cooking a variety of food/meals. In an embodiment, as shown, the exterior body of the cooking pots 106,107 is made square shaped, whereas the interior cavity for holding the cooking ingredients is made circular in shape. However, it should be understood that the cooking pots 106, and 107 including the interior cavity for holding the cooking ingredients may be made in different other shapes such as for example circular, rectangular, polygonal, etc. The cooking pots 106, 107 may be made using a variety of materials known in the art. In an example embodiment, the outer body of the cooking pots 106,107 may be preferably made of heat-insulating material. The top layer 106c 107c and bottom layers 106d,107d of the cooking pots 106,107 may be made of silicon or similar soft material to seal the attachment between the two pots 106,107 when one of the cooking pots 106,107 acts as a lid for the other pot 106,107 (the top layers 106c 107c of both the pots attaches together) or when the bottom layer 106d 107d of one of the pots 106,107 sits on top layer 106c 107c of the other pot 106,107. As seen, the cooking pots 106,107 further include a slot 106a,107a that allows a pair of heating arrangements 112 (that heats the food content held in the cooking pots 106,107) to detachably engage with the cooking pots 106, 107. The cooking pots 106,107 also include a handle 106b,107b that allows the user to attach and detach the cooking pots 106,107 to and from the pair of heating arrangements 112.

[0052] As the essence of the present invention, and at least shown in FIGS. 6-8, and FIGS. 17-18, the cooking system 100 uses a motion mechanism 108 configured within the housing 102 to allow the first cooking pot 106 and second cooking pot 107 to independently perform the movement in a 3 Degrees of Freedom (DoF) along a horizontal axis, a vertical axis, and a rotational axis. The innovative motion mechanism facilitates the pots 106,107 to orient in many different configurations or arrangements as shown in FIGS. 11-16. The motion mechanism 108 of the proposed invention can essentially be divided into a horizontal motion arrangement 109, a vertical motion arrangement 110, and a rotational motion arrangement 111 which will be discussed in detail in the description to follow.

[0053] In an embodiment, the horizontal motion arrangement 109 includes a first drive motor 109a with a first screw 109b. The screw 109b passes through a first horizontal carriage 109e and a second horizontal carriage 109f using the slots S1 and S2 respectively. In operation, when the first drive motor 109a receives the command from the control circuitry, it rotates the screw 109b to produce linear actuation to move the carriage 109e over a pair of horizontal guide rails 109g along the horizontal axis. The movement of the carriage 109e is linear in a forward or backward direction depending upon the requirement. In other words, the carriage 109e is moved towards or away from the carriage 109f. The speed of movement of the carriage 109e is controllable by the user by giving appropriate commands In some embodiments, the movements are controllable automatically depending upon the recipe being cooked. Additionally, the horizontal motion arrangement 109 includes a second drive motor 109c with a second screw 109d. The screw 109d passes through the second horizontal carriage 109f and the first horizontal carriage 109e via slots S3 and S4 respectively. In operation, the drive motor 109c rotates the screw 109d to produce linear actuation to move the carriage 109f over the pair of horizontal guide rails 109g along the horizontal axis. The movement of the carriage 109f is linear in a forward or backward direction depending upon the requirement. In other words, the carriage 109f is moved towards or away from the carriage 109e. The speed of movement of the carriage 109f is controllable by the user by giving appropriate command In some embodiments, the movements are controllable automatically depending upon the recipe being cooked. In an example embodiment, the drive motors 109a, and 109c may include but not limited to a stepper motor or a servo motor with the desired specification.

[0054] In an embodiment, the vertical motion arrangement 110 includes a third drive motor 110a with a third screw 110c. The drive motor 110a is configured on the first horizontal carriage 109e such that the screw 110c remains erected upwardly in a vertical axis from the carriage 109e. The screw 110c passes through a first vertical carriage 110e via slot V1. In operation, the third drive motor 110a (upon receiving a command from the control circuitry) rotates the screw 110c to produce linear actuation to move the carriage 110e over a first vertical guide rail 110g along the vertical axis. The vertical motion arrangement 110 further includes a fourth drive motor 110b with a fourth screw 110d. The motor 110b is configured on carriage 109f such that the screw 110d remains erected upwardly in the vertical axis from the carriage 109f. The screw 110d passes through a second vertical carriage 110f via slot V2. In operation, the drive motor 110b rotates the screw 110d to produce linear actuation to move the carriage 110f over a second vertical guide rail 110h along the vertical axis. The drive motors 110a, 110b may include but not limited to a stepper motor, and a servo motor with the desired specification.

[0055] In an embodiment, the rotational motion arrangement 111 includes a fifth drive motor 111a with a first drive shaft 111c. As seen, one of the heating elements 112 is rotatably coupled to the drive shaft 111c of the motor 111a so that the heating element 112 engaging the corresponding cooking pot 107 can rotate the cooking pot 107 along the rotational axis. The rotational motion arrangement 111 further includes a sixth drive motor 111b with a second drive shaft 111d. As seen, one of the heating elements 112 is rotatably coupled to the second drive shaft (111d) of the motor 111b so that the heating element 112 engaging the corresponding cooking pot 106 can rotate the cooking pot 106 along the rotational axis. The rotation of the drive shafts 111c, 111d may be clockwise or anticlockwise. In an embodiment, the drive motors 111a, 111b may include but not limited to a stepper motor or a servo motor.

[0056] All of these, horizontal motion arrangement 109, vertical motion arrangement 110, and rotational motion arrangement 111 helps in orienting the cooking pots 106,107 in different orientations depending upon the cooking requirement or recipe. For example, FIG. 11 and 12 shows the cooking pot 106 oriented in a manner to pour some ingredient into the other cooking pot 107 (so to say receiving pot). In these particular examples, it can be seen that only the cooking pot 106 is moved in along the horizontal axis, the vertical axis, and the rotational axis to orient itself in the pouring position over the cooking pot 107. Likewise, FIG. 13 shows the base/bottom 106d of the cooking pot 106 oriented over the top 107c of the cooking pot 107 in a spaced apart relation.
