The present disclosure relates to a cooking apparatus. More particularly, the present disclosure relates to a cooking apparatus that is configured to heat and stir-fry food.
In general, stir-fried food, such as stir-fried spicy pork, stir-fried webfoot octopus, stir-fried rice, etc., is prepared in a stir-frying manner where various ingredients are mixed together and are placed in a cooking container such as a frying pan, a pot, or the like, and then appropriately stir-fried while heating and stirring for a predetermined time.
In particular, in order to prepare stir-fried food using meat, such as beef, pork, poultry, etc., and various by-products, and also various seafoods such as webfoot octopus, long arm octopus, squid, etc., to be tasty, uniform heat should be evenly applied to food ingredients. For achieving this, a chef should continuously perform mixing of the ingredients for stir-fried food in front of a cooking table.
For example, when a chef grabs a handle of a pan and pulls with a small radius snap, then pushes and raises the pan, food ingredients accommodated at a bottom surface of the pan will rise quickly around an inner circumference of the pan and then flip over again to the bottom surface of the pan. In a similar manner, when the chef grabs the handle of the pan and pushes with a small radius snap, then pulls and raises the pan, the food ingredients accommodated at the bottom surface of the pan will rise quickly around the inner circumference of the pan and then flip over again to the bottom surface of the pan. By performing these repetitive movements, stir-fry cooking is performed.
However, in order for the chef to flip the food ingredients by using the pan, a snap of a wrist has to be performed, and there is a problem in that strain on a wrist joint or an arm joint occurs due to repeating of the repetitive snap movement.
In addition, since one chef may only prepare one food at once, it is difficult to prepare a large amount of foods or different types of stir-fried foods at the same time. Therefore, there is a need for solving these problems.

As illustrated in
By the second motor member 41 that uses a stepping motor, an inclination of the inner portion 10 is capable of being controlled. When a system of the cooking apparatus 1 is operated, the second driving portion 40 is operated so that the inner portion 10 is positioned to be in a vertical direction. Since the second motor member 41, which is the stepping motor, is operated and adjusts the inclination of the housing portion 25, the inner portion 10 and the outer portion 20 that are positioned inside the housing portion 25 are rotated together with the housing portion 25.
The second motor member 41 is installed at a position spaced apart from the housing portion 25, and various types of motors may be used within the technical idea of converting electrical energy to rotational power. The stepping motor is used as the second motor member 41 according to an embodiment of the present disclosure. Moreover, a servo motor may be used as the second motor member 41.

The power transmitting portion 43 according to an embodiment of the present disclosure extends in a horizontal direction, and has a first side fixed to the outside of the housing portion 25 and has a second side connected to the second output shaft 42 of the second motor member 41. Therefore, the housing portion 25, which receives power of the second motor member 41, may be rotated in the second direction A2.
The target measurement member 44 is fixed to the power transmitting portion 43, and is a metal piece that is rotated together with the power transmitting portion 43. In addition, the sensor member 45 is installed at a position facing a movement path of the target measurement member 44, and is configured to detect a movement of the target measurement member 44 in a non-contact manner.
The inner portion 10, which corresponds to the stir-fry container, rotates together with the housing portion 25, and the housing portion 25 rotates together with the power transmitting portion 43. In addition, the target measurement member 44 installed at the power transmitting portion 43 also rotates together with the power transmitting portion 43 so that the inner portion 10 and the target measurement member 44 rotate together. The inner portion 10 is installed in the vertical direction that is an initialization position, and the target measurement member 44 is positioned facing the sensor member 45 when an entrance of the inner portion 10 is installed in an upward direction. Therefore, the sensor member 45 detects the movement of the target measurement member 44 and allows the inner portion 10 to be in a stopped state.
The inner support portion 46 supports the second motor member 41, and may be moved in the vertical direction together with the second motor member 41. The inner support portion 46 is positioned at a lower portion of the second motor member 41, and the second motor member 41 is fixed to an upper side of the inner support portion 46.

Since the curved portion 63 in contact with the food 300 is concavely formed, the food 300 contained in the inner portion 10 may be easily stirred.
The second stirring portion 70 is installed in a direction intersecting with the first stirring portion 60, and is positioned at the base member 11 of the inner portion 10. In addition, the second stirring portion 70 stirs the food 300 together with the first stirring portion 60, and the second stirring portion 70 may be variously modified within the technical idea of being in a state in which the second stirring portion 70 maintains a fixed state and is not with the outer portion 20. The second stirring portion 70 according to an embodiment of the present disclosure may include: a core member 71 positioned at an upper side of the base member 11 and provided with magnetic poles at both sides thereof; and a fixing member 72 fixed to the inside of the housing portion 25 facing the core member 71 and provided with opposite magnetic poles. In addition, when the inner portion 10 is rotated, a rotation of the core member 71 may be restrained by the fixing member 72.
In addition, when the core member 71, which uses a magnet, is in a state of being in contact with the base member 11 of the inner portion 10, the core member 71 maintains a state in which the rotation of the core member 71 is restrained, and also when the food 300 is discharged, the core member 71 having a bar shape is blocked from moving outside of the inner portion 10. If the core member 71 has a weak fixation power, a separate electromagnet may be additionally installed.
A permanent magnet may be used as the fixing member 72, and an electromagnet may be used as necessary. The core member 71 is attached by magnetic force. The fixing member 72 that is fixed to the inside of the outer portion 20 has the magnetic poles that are opposite to a polarity of the core member 71. Therefore, the core member 71 positioned at the inside of the inner portion 10 is fixed in a predetermined direction by magnetism.
When the inner portion 10 is rotated, the food 300 existing at the inside of the inner portion 10 rotates, and since the core member 71 that is a magnetic bar is fixed, the core member 71 evenly mixes the food 300.
As the magnet used for the core member 71 and the fixing member 72, a neodymium magnet, a samarium-cobalt magnet, or an alnico magnet may be used. Additionally, a solenoid electromagnet may be used.
In the present disclosure, by using the first stirring portion 60 and the second stirring portion 70, the food 300 may be rapidly and easily mixed. The food 300 is stirred by a double action of the first stirring portion 60 and the second stirring portion 70.
The heating portion 80 may be variously modified within the technical idea of using electrical energy to heat the inner portion 10. The heating portion 80 according to an embodiment of the present disclosure may include an induction wire 81 that is installed in a shape that surrounds the outside of the outer portion 20. When the induction wire 81 is operated, the inner portion 10 is heated by eddy currents generated by magnetic induction so that the food 300 is heated.
As illustrated in
The body portion 91 is positioned at a lower side of the housing portion 25, and is connected to the lower side of the second driving portion 40. The water collecting portion 92 is formed to be concaved toward a center portion thereof, and a water draining portion 94 is installed at the center portion of the water collecting portion 92.
As illustrated in
In addition, an electrical component related to the direct-firing portion 100 is positioned inside a direct-firing base portion 104, and the fuel gas and the air are moved along the direct-firing pipeline 101 that extends to an upper side of the direct-firing base portion 104. The movement of the fuel gas and the air is controlled by the valve portion 102 that is installed at the direct-firing pipeline 101, and flame is injected through the nozzle portion 103 that is installed at an end portion of the direct-firing pipeline 101.
Hereinafter, an operation state of the cooking apparatus 1 according to an embodiment of the present disclosure will be described in detail with reference to the accompanying drawings.
In addition, when a direct-fired cooking is needed, the food 300 existing in the inner portion 10 is heated by flame generated through the nozzle portion 103.
After the food 300 has been cooked, the second motor member 41 is operated and rotates the housing portion 25 so that the food 300 is capable of being moved to another container by changing the inclination angle of the inner portion 10.
As illustrated in
As illustrated in
In addition, water injected from the injecting portion 93 cleans a remnant that has remained in the inner portion 10, and moves downward. Cleaning water moved along the water collecting portion 92 moves outside the body portion 91 through the water draining portion 94.
A temperature of the inner portion 10 is maintained high, and when pressure of water is injected from the injecting portion 93, contents attached to the inner portion 10 or oil attached to the inner portion 10 may be easily removed.
Hereinafter, another embodiment that the inner portion 200 of the present disclosure is installed in an oval shape will be described with reference to the accompanying drawings.
As illustrated in
When it is assumed that the inner portion 200 is rotated in a counter-clockwise direction, a height of contents positioned at a left side is relatively lower than a height of contents positioned at a right side so that the contents positioned at the right side flow down to the left side and are mixed. In other words, when rotating from a wide area of the floor to a narrow area of the floor, the contents positioned at a higher portion flow down to the left side and are in contact with an inner surface of the inner portion 200. Therefore, as the inner portion 200 is rotated, the food 300 is positioned at the bottom portion of the inner portion 200 so that the mixing of the food 300 may be more easily realized.
When the inner portion 200 has a circular cross-sectional shape, the food 300 positioned at a lower side continuously be in contact with the inner surface of the inner portion 200 so that the mixing does not occur well, and is only mixed by the first stirring portion 60 and the second stirring portion 70.
Therefore, when the inner portion 200 has the oval cross-sectional shape, the mixing of the food 300 may be more easily realized.
As described above, since the rotation and the inclination angle of the inner portion 10 and 200 are capable of being adjusted by using the first driving portion 30 and the second driving portion 40, a time and a cost for preparing the food 300 may be reduced since the food 300 is automatically heated by the heating portion 80 and the direct-firing portion 100. In addition, the food 300 is easily mixed by the first stirring portion 60 and the second stirring portion 70, and the inclination angle of the inner portion 10 and 200 is capable of being adjusted by using the second driving portion 40 so that various tastes of the food 300 may be prepared since the food 300 is mixed and stir-fried in various manners. In addition, since the cleaning of the inner portion 10 and 200 is automatically performed by the injecting portion 93, time and cost required to clean the inner portion 10 and 200 may be reduced.
In the present disclosure, a central processing unit 250 is configured to control a movement of the first driving portion 30, the second driving portion 40, the elevating portion 47, and a horizontal moving portion 110.
In addition, a first driving controller 30a configured to control a rotation and a speed of the first motor member 31 exists at the first driving portion 30, and a second driving controller 40a configured to control a rotation, a rotation angle, and a rotation speed of the second motor member 41 exists at the second driving portion 40. Moreover, an elevating controller 47a configured to control an elevating power of a hydraulic pressure or a pneumatic pressure exists at the elevating portion 47, and a horizontal moving controller 110a configured to control a rotary motor that is configured to provide a power of a horizontal movement exists at the horizontal moving portion 110.
As described in the previous embodiment of the present disclosure, the first driving portion 30 drives the inner portion 10 to be rotated in the first direction A1, and the second driving portion 40 drives the housing portion 25 to be rotated in the second direction A2. In addition, the elevating portion 47 drives the inner support portion 46 to be vertically moved. Moreover, the horizontal moving portion 110 is a driving portion that is configured to allow the container support stand 120 to which the completely cooked food is added to be horizontally moved when that the completely cooked food is automatically discharged.
As a result, by an algorithm stored in a memory portion 255, the central processing unit 250 controls a rotation driving in the first direction A1, a rotation driving in the second direction A2, an elevation driving that generates the vertical movement, and a driving of the horizontal movement of the container support stand 120.
When the food is completely cooked by the control of the central processing unit 250, a cooking is finished, and the algorithm performing the cooking is finished. (step 350)
Then, the central processing unit 250 operates a stir-fried food discharging algorithm that discharges a stir-fried food cooked by the cooking apparatus of the present disclosure. (step 355)
By the elevating portion 37 that controls the elevating power in a hydraulic pressure manner or a pneumatic pressure manner, the housing portion 25 in which the food 300 is accommodated and the stir-fry cooking is performed is lifted upward. (step 360)
The container stand support 120 in which the food that cooking is finally completed is discharged is moved below the housing portion 25. By the control of the central processing unit 250 and the horizontal moving controller 110a, the horizontal moving portion 110 allows the container stand support 120 to perform a circular movement in a horizontal direction. (step 365)
In order for the completely cooked food accommodated in the inner portion 10 provided inside the housing portion 25 to be added to the container support stand 120, the housing portion 25 is rotated up to a predetermined angle by the second driving portion 40. (step 370)
When the completely cooked food is discharged to the container support stand 120, the container support stand 120 is moved to an original position thereof by the horizontal moving portion 110. Moreover, the cooking apparatus of the present disclosure performs a cleaning process. In order to perform the cleaning process, the central processing unit 250 operates a cleaning algorithm. (steps 375 to 380)
When after the step 360 that the housing portion 25 is lifted upward by the elevating portion 47 and the step that the container support stand 120 in which the discharged food is accommodated being moved below the housing portion 25 are simultaneously performed, the step 370 that the housing portion 25 is rotated up to the predetermined angle by the second driving portion 40 and the step that the container support stand 120 in which the discharged food is accommodated being moved below the housing portion 25 may be simultaneously performed.
The container support stand 120 is connected to the horizontal moving portion 110 by a connecting arm 112, and the horizontal moving portion 110 provides a power that the container support stand 120 is horizontally moved via the connecting arm 112.
At this time, during the stir-fry cooking is performed by the inner portion 10 in the housing portion 25, the container support stand 120 is positioned outside an edge border of the receiving portion 90.
By the elevating portion 47 controlling the elevating power in the hydraulic pressure manner or the pneumatic pressure manner, the housing portion 25 in which the food 300 is accommodated and the stir-fry cooking is performed is lifted upward, and the container support stand 120 is moved below the housing portion 25. In addition, the housing portion 25 performs the rotation movement (rotation by the second driving portion 40) in an angle that the food 300 accommodated in the inner portion 10 is to be easily discharged from the container support stand 120.
As a result, due to the lift of the housing portion 25, the horizontal movement of the container support stand 120, and the rotation movement of the housing portion 25, a position to which the food 300 existing in the inner portion 10 in the housing portion 25 is discharged is formed.
The container support stand 120 is moved to the original position thereof (the container support stand 120 is positioned to be outside the edge border of the receiving portion 90) by the horizontal movement, and the opening portion of the housing portion 25 is positioned to be in a state of facing downward so that the cleaning process is performed. In addition, the cleaning process is as described the previous embodiment of the present disclosure.
An angle of the housing portion 25 is inclined as the embodiment in
When the housing portion 25 is in an inclined state such that the food is discharged, a diameter L of the container support stand 120 is formed to be longer than a distance (denoted by A in
In addition, when the housing portion 25 is in an inclined state such that the food is discharged, the diameter of the container support stand L is formed to be longer than a distance (denoted by B in
At this time, since the food being discharged may be discharged outside the container support stand 120, the diameter L of the container support stand 120 is preferable to be 20 % longer than the two distances above described.
By the control of the central processing unit 250 and the horizontal moving controller 110a, the horizontal moving portion 110 allows the container support stand 120 to perform the circular movement in the horizontal direction (rotated in a clockwise or counterclockwise direction with respect to the connecting arm 112 as a shaft). Then, power of the circular movement is provided by the horizontal moving portion 110. The horizontal moving portion 110 provides power of the rotation movement with supporting an end portion of the connecting arm 112, and as illustrated in a dotted line in
By the control of the central processing unit 250 and the horizontal moving controller 110a, the horizontal moving portion 110 allows the container support stand 120 to perform the circular movement (direction of arrow illustrated in
Of course, the horizontal movement occurred by the circular movement is an embodiment of the present disclosure, and such a rectilinear gear and so on may be provided at a lower portion of the container support stand 120 and a horizontal movement occurred by the rectilinear gear may be realized according to an embodiment of the present disclosure.
As described above, the present disclosure is described with reference to the drawings. However, the present disclosure is not limited by the embodiments and drawings disclosed in the present specification. It will be apparent that various modifications may be made thereto by those skilled in the art within the scope of the present disclosure. Furthermore, although the effect resulting from the features of the present disclosure has not been explicitly described in the description of the embodiments of the present disclosure, it is obvious that a predictable effect resulting from the features of the present disclosure should be recognized.
