Detailed Description

Hereinafter, embodiments of the present invention are described in detail with reference to the accompanying drawings.

Referring to fig. 1, a cooking machine 100 according to an exemplary embodiment of the present disclosure may include a temperature sensor 110, a stirring unit 120, a heating unit 130, a memory 140, an input unit 150, a display unit 160, a processor 170, and a cooking container 180.

According to an embodiment, cooking machine 100 may be a machine for heating cooking container 180 configured separately from cooking machine 100, and may be, for example, an electric rice cooker, a multifunctional cooking appliance, a mechanical cooking appliance, or the like. According to an embodiment, the cooking machine 100 may also be a machine for heating the cooking container 180 integrated with the cooking machine 100.

The temperature sensor 110 may generate temperature data, i.e., a sensing signal, representing the temperature of the cooking container 180 or the contents contained in the cooking container 180. For example, the temperature sensor 110 may include at least one of a lower temperature sensor disposed at a lower portion of the cooking container 180 and an upper temperature sensor disposed at an upper portion of the cooking container 180. In one embodiment, the lower temperature sensor 111 may be embodied as a plurality of lower temperature sensors. However, the present invention is not limited thereto, and the temperature sensor 110 may further include: a side surface temperature sensor disposed on a side surface of the cooking receptacle 180 or a temperature sensor disposed in the stirring unit.

The stirring unit 120 may include a driving motor, a rotating shaft, and a rotating blade. The driving motor may be a Switched reluctance motor (SR motor), and the stirring unit 120 may further include an SR motor driving system for driving the SR motor. The SR motor driving system may include an SR motor, an SR motor driver, a driving controller, and a position sensor unit. The SR motor driver, the drive controller, and the position sensor unit may be referred to as a driving circuit for driving the SR motor.

The SR motor can obtain a rotational force by using a Reluctance Torque (Reluctance Torque) that occurs with a change in Reluctance. The SR motor may include a stator (stator) and a rotor (rotor). According to an exemplary embodiment, the stator and the rotor may be composed of a magnetic substance having a high magnetic permeability. For example, the stator and the rotor may have a structure in which silicon steel plates are laminated.

The SR motor according to an exemplary embodiment may have a double salient pole (double salient pole) structure in which both the stator and the rotor have a salient pole type structure. The stator and the rotor may include a plurality of salient poles (salient-poles), respectively. A coil may be wound on the salient pole of the stator, a shaft of the SR motor may be connected at the center of the rotor, and a sensor magnet rotating simultaneously with the rotor may be mounted on the shaft or the rotor.

The SR motor according to an exemplary embodiment may have a four-phase motor structure. For example, the stator of the SR motor may include eight salient poles (e.g., a pole, B pole, C pole, D pole, a 'pole, B' pole, C 'pole, and D' pole), and the rotor may include six salient poles. The coil may be wound around a plurality of salient poles facing each other in the stator.

When the magnetic flux passes through the rotor, a current is generated in the rotor, and the SR motor may be rotated by a torque (torque) generated due to the magnetic flux of the stator being locked with the magnetic flux of the rotor. In other words, the SR motor may use torque generated due to a magnetic attraction force that causes an action between the stator and the rotor. For example, the rotor may be rotated as voltages are sequentially applied to the a-phase, B-phase, C-phase, and D-direction coils corresponding to the salient poles of the stator. The SR motor may be interconnected by an SRM driver and six wires.

The driving motor may be connected to the rotary blade via a rotary shaft to transmit a rotary driving force to the rotary blade. The rotary blade may include various forms such as a rotary blade or a propeller for circulating water, etc., in addition to the pulverizing blade of the mixer.

However, the configuration of the heating unit 130 is not limited thereto, and the heating unit 130 may have various configurations for heating the cooking container 180.

The memory 140 may store a control algorithm related to the operation of the processor 170 and/or various data generated by the execution of the control algorithm. The memory 140 may include volatile memory or non-volatile memory devices. Also, the memory 140 may be provided within the processor 170, for example, may be a register provided within the processor 170. For example, processor 170 and processor 140 may be embodied as a microcomputer (MICOM). However, the present invention is not limited thereto, and the processor 170 may be embodied as a processor such as a logic circuit or a Central Processing Unit (CPU), a Field Programmable Gate Array (FPGA), an Electronic Control Unit (ECU), or the like.

The input unit 150 may receive user input and may include a plurality of input buttons and/or a smart dial for receiving various user inputs. In an embodiment, the input unit 150 may receive a user input indicating a start of a cooking operation, a reservation, a selection of a cooking item, a start of a keep warm operation, and the like. For example, the input unit 150 may sense touch input according to various manners such as a decompression manner and a capacitance manner.

The display unit 160 may output state information, setting information, or information corresponding to user input, etc. of the cooking machine 100. For example, the display unit 160 may further include a speaker. For example, the Display unit 160 may include one of various Display devices such as a Liquid Crystal Display (LCD), a Plasma Display Panel (PDP), a Thin-film transistor Liquid Crystal Display (TFT LCD), and an Organic Light-emitting Diode (OLED).

For example, the user may select an icon indicating that the cooking machine 100 starts a cooking operation from the application program, and the communication unit may receive a user input indicating that the cooking operation is started. At this time, the processor 170 may start a cooking operation in response to the received user input.

Referring to fig. 2, the cooking machine 200 may include a cover 210, an outer pot 240 inserted into the interior of the cooking machine 200, and a filter bowl 220 (or inner pot) disposed inside the outer pot 240 and receiving cooking materials. The culinary item may have the form of a cereal, such as rice. The cooking machine 200 may further include a stirring unit including a rotating blade 250 and a driving motor 260.

For example, the cover 210 may be hinged to an upper portion of the body and rotated (pivot) around a rotation axis, and may be rotated around the rotation axis to open or close the cooking space. In particular, the cover 210 may close the cooking space so that an appropriate temperature and pressure are formed in the cooking space during cooking of cooking objects such as rice and water.

The filter bowl 220 may be installed in the outer pot 240. According to an embodiment, the filter basin may also be a steamer. The filter bowl 220 may be disposed at an upper portion of the outer pot 240 and may be spaced apart from a bottom of the outer pot 240 by a first height.

The body 200 may further include a heating unit for heating the outer pot 240. The outer pot 240 may be formed of a material suitable for heating by heat provided from the heating unit. The outer pan 240 may be a large bowl shaped member.

In general cooking, the cooking materials may be contained in the space formed in the outer pot 240. In contrast, when cooking is performed in a way of reducing the sugar, the cooking materials may be contained in the space formed in the filtering basin 220, and the filtering basin 220 may be installed in the outer pot 240. The filter bowl 220 may be located at a position spaced apart from the bottom of the outer pot 240 by a predetermined height. The sugar or the like separated from the cooked material during cooking may be dissolved in water. The water inside the outer pot can be rapidly rotated by the stirring unit and can flow into the inside of the filter bowl 220 through the sidewall holes. Also, the water inside the outer pot may be heated by the heating unit, and the heated water may flow into the inside of the filtering basin 220 through the sidewall hole in the form of steam or in a liquid state having high kinetic energy. When cooking, water inside the filter bowl 220 may flow out of the outside through the bottom hole. Accordingly, the water contained in the filtering basin 220 may be circulated, and the water having the sugar dissolved therein flows out of the outside of the filtering basin 220, with the result that the cooking material may be cooked in a state having a low sugar.

The cooking machine according to the exemplary embodiment of the present disclosure includes the straining basin 220 which is located at a height spaced apart from the bottom of the outer pot 240, and may induce water circulation through a plurality of bottom holes formed at the bottom surface of the straining basin 220 and a plurality of side walls formed at the side walls, so that the cooked food having low sugar content may be cooked.

In order to cook rice with low sugar, the cooking machine 200 may provide guidance on the water 20 or the rice 10. For example, a guide unit indicating the height of the water 20 or the height of the rice 10 according to the number of people who cook may be formed at the sidewall of the filtering basin 220. The guide unit may provide a guide with respect to a plurality of heights, and the state of the cooking items contained inside the filter bowl 200 at the end of cooking may depend on the respective heights. For example, the user can adjust the height of the water 20 according to the indication of the guidance unit to set the state of the cooking material at the end of cooking to a high viscosity state or a low viscosity state.

Referring to fig. 3A, in starting low-sugar rice cooking, the rice 10 may be in a form of being sufficiently immersed in water 20. Initially, the cooking machine 200 may heat the cooking object or water 20 through the heating unit while circulating the water to the filtering basin 220 by rotating the rotary blade 250. The rotary blade 250 can wash the rice 10 inside the filter bowl 220 by rotating at a first speed at which water can reach the upper end of the filter bowl 220 or the sidewall hole thereof to reduce the saccharinity.

During cooking, as the rice 10 absorbs the water 20, the height of the water 20 may gradually decrease, as shown in fig. 3B. Even in the case where the water level is lowered, the cooking machine 200 may rotate the rotary blade 250 to allow water to flow into the inside of the straining basin 220 through a sidewall hole formed at a side surface of the straining basin 220.

The cooking machine 200 can continue to heat the rice 10 that absorbs the water 20 through the swelling-water absorbing process during the cooking process. Referring to fig. 3C, in a state that the rice 10 has sufficiently absorbed the water 20 and the water 20 is evaporated to the extent that the filter bowl 220 is not immersed in the water 20, the rotary blade 250 may rotate at a second speed to prevent the water 20 from overflowing while steaming the rice 10. The cooking machine 200 may heat the remaining water 20 through the heating unit to steam rice using steam.

Further, the cooking machine 200 may stop the heating operation of the heating unit or control the intensity of the heating operation to be weak in order to smother the cooking object.

The filter bowl 300 may include a bottom surface 320 and a sidewall 310. At least one bottom hole may be formed on the bottom surface 320 of the filter bowl 300, and at least one side wall hole may be formed on the side wall 310 of the filter bowl 300. The bottom surface 320 may contain cooking materials, and at least one bottom hole 322H may be formed on the bottom surface 320. The sidewall 310 may be formed in a vertical direction from the bottom surface 320, and at least one sidewall hole 312H may be formed on the sidewall 310.

For example, the bottom and side wall apertures may be sized smaller than the size of the cooking items contained in the filter basin 300. Thus, in the reduced sugar mode, the cooking product held in the filter bowl 300 is maintained within the filter bowl 300 without slipping through the bottom or side wall apertures. The outer pot may contain water in order to prepare the cooking product. In the case of water contained inside the outer pot for cooking, the water may also flow through the bottom hole into the interior of the filter bowl 300, which is spaced from the bottom. A guide unit (not shown) may be formed on the sidewall of the filtering basin 300 to guide the water level for cooking. The user can adjust the water level for cooking the cooking items contained in the filter bowl 300 with reference to the guide unit.

The sugar or the like separated from the cooked material during cooking can be dissolved in water. The water inside the outer pot can be rapidly rotated by the stirring unit and can flow into the inside of the filter bowl 300 through the sidewall hole. Further, the water inside the outer pot may be heated by the heating unit, and the heated water may flow into the filter bowl 300 through the sidewall hole in the form of steam or in a liquid state having high kinetic energy. When cooking, water inside the filter bowl 300 may flow out of the outside through the bottom hole. Accordingly, the water contained in the filtering basin 300 can be circulated, and the water in which the sugar is dissolved flows out of the filtering basin 300, the cooked food can be cooked in a state of having a low sugar.

In one example, the sidewall hole 312H formed on the sidewall 310 may be formed to have a preset height b and width a. Width a may have a small value to minimize cooking products including grains from sliding out of the outside of the filter bowl 300, and conversely height b may have a relatively large value to encourage water to flow into and out of the inside of the filter bowl 300. The height b and the width a may be experimentally determined considering the size of the cooked food including the low sugar cooking grain. The bottom aperture 322H may be the same size or shape as the sidewall aperture 312H and may be formed smaller to minimize outflow of the cooking contents.

The bowl 300 may further include a sealing ring portion 350. The sealing ring portion 350 may be composed of a material such as silicon, and may stably fix the bowl 300, or may prevent the bowl 300 or the outer pot from being damaged.

Referring to fig. 5, the filter bowl 300 may include a bottom surface 320 and a sidewall 310. At least one bottom hole may be formed on the bottom surface 320 of the filter bowl 300, and at least one side wall hole may be formed on the side wall 310 of the filter bowl 300. The bottom surface 320 may contain cooking items, and at least one bottom hole may be formed on the bottom surface 320. The sidewall 310 may be formed in a vertical direction from the bottom surface 320, and at least one sidewall hole may be formed on the sidewall 310. The filter bowl 300 may further include a sealing ring portion 350. The sealing ring portion 350 may be composed of a material such as silicon, and may stably fix the bowl 300, or may prevent the bowl 300 or the outer pot from being damaged.

Fig. 6 is a diagram for describing a process of making low-sugar rice by using the cooking machine according to the exemplary embodiment of the present disclosure.

Referring to fig. 6, the cooking machine may cook low-sugar rice through a first step of swelling rice, a second step of making the rice absorb moisture, a third step of heating the cooked food, and a fourth step of braising the cooked food.

The cooking machine may start the cooking operation by the heating unit at the step of swelling the rice. The cooking machine may adjust the heating speed in consideration of time required for the rice to absorb moisture, etc. The cooking machine may maintain a temperature suitable for the rice to absorb moisture for a preset time. During the rice steeping step, the cooking machine may rotate the rotating blades at a first speed to remove sugar so that water may be fully circulated to the filter basin. For example, the first rotational speed may be 350 RPM.

The cooking machine may heat the cooking object to and maintain the first target temperature during the cooking step. The cooking machine can rotate the rotating blade at a second speed at a specific temperature so as not to pop up the cooked object. For example, the cooking machine may obtain an effect such as continuously stirring the water of the next rice by rotating the rotating blades at a speed of 200 RPM.

The cooking machine may stop heating the cooking item at the simmering step or may maintain the heating at a weaker intensity. In the cooking step, the cooking machine may cook the cooking materials while opening a lid of a feeding port of the cooking machine to discharge steam. During the step of braising, the cooking machine may stop the rotating blade.

Fig. 7 is a flowchart for describing a process of making low-sugar rice by using the cooking machine according to an exemplary embodiment of the present disclosure.

Referring to fig. 3A and 7, the cooking machine 200 may swell the rice 10 contained inside the straining basin and remove the sugar (S110). The rice 10 may be in a state of being sufficiently latent in the water 10 at the time of starting low-sugar rice cooking. Initially, the cooking machine 200 may heat the cooking object or water 20 through the heating unit while circulating the water to the filter bowl 220 by rotating the rotary blade 250. The rotary blade 250 can wash the rice 10 inside the filter bowl 220 to reduce the sugar content by rotating at a first speed at which water can reach the upper end of the filter bowl 220 or the sidewall hole thereof. The cooking machine 200 may repeatedly circulate the water contained inside the outer pot to the inside of the filter bowl through the stirring unit.

The cooking machine 200 may heat water contained inside the outer pot (S120). During cooking, as the rice 10 absorbs the water 20, the height of the water 20 may gradually decrease, as shown in fig. 3B. Even in the case where the water level is lowered, the cooking machine 200 may rotate the rotary blade 250 to allow water to flow into the inside of the straining basin 220 through a sidewall hole formed at a side surface of the straining basin 220.

The cooking machine 200 can continue to heat the rice 10 that absorbs the water 20 through the swelling-water absorbing process during the cooking process. Referring to fig. 3C, in a state that the rice 10 has sufficiently absorbed the water 20 and the water 20 is evaporated to the extent that the filter bowl 220 is not soaked in the water 20, the rotary blade 250 may be rotated at the second speed to prevent overflow when the rice 20 evaporates the rice 10. The cooking machine 200 may heat the remaining amount of water 20 by the heating unit and steam rice (S130).

The cooking machine according to the technical concept of the present disclosure may remove sugar included in rice by circulating water through a stirring unit included in the cooking machine. Also, the low sugar rice can be cooked by efficiently circulating water through the filtering basin included in the cooking machine.

The technical idea of the present disclosure described above is not limited to the foregoing embodiments and the accompanying drawings. Also, it will be apparent to those skilled in the art that various substitutions, modifications, changes, and the like can be made without departing from the technical spirit of the present disclosure.
