Therefore, conventionally, an automatic cooking device has been known that includes a container holding unit that holds a bottomed cylindrical cooking container, a rotating unit that rotates the cooking container held in the container holding unit freely between the front and rear areas of the cooking table, and a control unit that drives and controls the container holding unit and rotating unit, and that at least stirs and cooks ingredients contained in the cooking container, in which the cooking container has a stirring member that is provided on the inner bottom surface or inside surface of the container body and protrudes into the internal space of the container body (for example, Patent Document 1). [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Japanese Patent Publication No. 2022-175791 Summary of the Invention [Problem to be solved by the invention]
[0004] However, in the above-mentioned automatic cooking device, since the stirring member rotates integrally with the container body, there is room for further improvement in reproducing the skilled stirring technique of a chef.
[0005] Therefore, the present invention solves the problems of the prior art as described above, and the object of the present invention is to provide an automatic cooking device that more realistically and highly reproduces the well-trained stirring technique of a chef. [Means for solving the problem]
[0006] The invention of claim 1 is an automatic cooking device that comprises a cooking container having a bottomed cylindrical container body for containing ingredients and a stirring member for stirring the ingredients contained in the container body, and a container holding unit that holds the cooking container so that it can rotate freely, and that stirs and cooks the ingredients contained in the cooking container, wherein the container holding unit has a container rotation shaft that engages with the container body of the cooking container and transmits container rotation torque to the container body, causing the container body to rotate around its central axis, and a stirring member rotation shaft that rotates independently of the container rotation shaft, and thereby forms a magnetic coupling mechanism that transmits stirring member rotation torque non-contact between the stirring member rotation shaft of the container holding unit and the stirring member of the cooking container, thereby solving the above-mentioned problem.
[0007] The invention of claim 2 solves the above-mentioned problem by, in addition to the configuration of the automatic cooking device described in claim 1, forming a convex portion on the bottom surface of the container body to be inserted into the concave portion of the stirring member, holding a spherical body that makes point contact with the concave portion of the stirring member on the upper surface of the convex portion, and positioning the bottom surface of the container body and the stirring member facing each other at a distance.
[0008] The invention of claim 3 further solves the above-mentioned problem by, in addition to the configuration of the automatic cooking device described in claim 1, forming an anti-rotation protrusion on either the container body of the cooking container or the container rotation shaft of the container holding unit, and forming an anti-rotation groove that engages with the anti-rotation protrusion on the other of the container body of the cooking container or the container rotation shaft of the container holding unit.
[0009] The invention of claim 4 further solves the above-mentioned problem by, in addition to the configuration of the automatic cooking device described in any one of claims 1 to 3, the container body of the cooking container being formed from a side made of a magnetic material that is induction heated by the container heating unit, and a bottom surface that includes a non-magnetic material area. [Effects of the Invention]
[0010] According to the automatic cooking device of the invention of claim 1, the container holding unit has a container rotation shaft that engages with the container body of the cooking container and transmits container rotation torque to the container body, causing the container body to rotate around the central axis of the container body, and a stirring member rotation shaft that rotates independently of the container rotation shaft.A magnetic coupling mechanism is formed between the stirring member rotation shaft of the container holding unit and the stirring member of the cooking container to transmit the stirring member rotation torque non-contact, allowing the stirring member to rotate independently of the container body.Therefore, by rotating the stirring member faster or slower than the container body, the stirring member can be rotated more realistically and to a higher degree, thereby reproducing the chef's well-trained stirring skills, and a wide variety of dishes can be cooked. Furthermore, by configuring a magnetic coupling mechanism that transmits the rotational torque of the stirring member non-contact between the stirring member rotating shaft of the container holding unit and the stirring member of the cooking container, the bottom of the container body has a simpler shape than when the stirring member is fixed to the container body with screws, etc., which eliminates ingredients from remaining at the attachment point between the stirring member and the container body, and also makes it easy to attach and detach the stirring member to the container body during maintenance.
[0011] According to the automatic cooking device of the invention of claim 2, in addition to the effects achieved by the automatic cooking device of the invention of claim 1, the spherical body that makes point contact with the concave portion of the stirring member is held on the upper surface of the convex portion, and the bottom surface of the container body and the stirring member are arranged facing each other at a distance, thereby reducing the sliding resistance between the container body and the stirring member, and allowing the stirring member to rotate more reliably and at higher speeds relative to the container body.
[0012] According to the automatic cooking device of the invention of claim 3, in addition to the effects achieved by the automatic cooking device of the invention of claim 1, an anti-rotation protrusion is formed on either the container body of the cooking container or the container rotation shaft of the container holding unit, and an anti-rotation groove that engages with the anti-rotation protrusion is formed on the other of the container body of the cooking container or the container rotation shaft of the container holding unit.Therefore, the cooking container and the container holding unit are positioned and held relative to each other simply by engaging the anti-rotation protrusion with the anti-rotation groove, and the container body rotation torque can be reliably transmitted from the container holding unit to the container body of the cooking container with a simple structure.
[0013] According to the automatic cooking device of the invention of claim 4, in addition to the effects achieved by the automatic cooking device of the invention of any one of claims 1 to 3, the container body of the cooking container is formed from a side made of a magnetic material that is induction heated by the container heating unit, and a bottom surface that includes a non-magnetic material area.Therefore, the magnetic circuit formed by the side of the container body and the container heating unit is separate from the magnetic circuit formed within the magnetic coupling, so that it is possible to reliably achieve both rotation of the container body and stirring member by the container holding unit and induction heating by the container heating unit.

[0027] The cover 700 is rotatable about a cover central axis extending in the left-right direction. Most of the cover 700 is made of a mesh so that the inside of the cooking vessel 300 can be seen when the open surface of the cooking vessel 300 is covered.
[0028] The control unit 800 has an operation panel 810 for operation and an emergency stop button 820 for urgently stopping the cooking operation of the automatic cooking apparatus 10, and controls the operation of each unit based on input to the operation panel 810.
[0029] The control unit 800 further includes at least a processor, a main storage device, an auxiliary storage device, and a network interface, none of which are shown. The components that make up the control unit 800 are connected via a bus, which is a data transmission path between the components. The processor is realized by a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit), and executes various processes according to programs stored in a main storage device or an auxiliary storage device. The main memory device is configured with SRAM (Static Random Access Memory), DRAM (Dynamic RAM), flash memory, or the like, and temporarily stores data required for the control unit 800 to perform arithmetic processing.

[0030] <2. Details of the container holding unit and cooking container> Next, the container holding unit 200 and the cooking container 300 will be described in detail with reference to FIGS. Figure 2 is an assembly diagram of the main parts of the automatic cooking device 10 shown in Figure 1, Figure 3A is a partial cross-sectional view of the left side of the automatic cooking device 10 shown in Figure 1, Figure 3B is an enlarged view of IIIB in Figure 3A, Figure 4A is a schematic diagram showing the magnetic circuit formed in the automatic cooking device 10 shown in Figure 1, Figure 4B is an enlarged view of IVB in Figure 4A, and Figure 5 is an exploded view of the stirring member 320 shown in Figure 2. In FIG. 2, serving plate 131 slides to close the opening of sink 120.
[0031] <2.1. Container holding unit> As shown in Figure 2, etc., the container holding unit 200 has a base 210 provided on the top surface 100A of the cooking table 100, a rotating part 220 that can be rotated freely in the forward and backward directions relative to the base 210, and a handle 230 (see also Figure 1) attached to the rotating part 220 and held by a user of the automatic cooking device 10. Therefore, in this embodiment, when a user of the automatic cooking apparatus 10 grips the handle 230 and moves the rotating part 220 back and forth relative to the base part 210, the cooking container 300 held by the container holding unit 200 rises and falls back and forth.
[0032] The rotating portion 220 holds the cooking container 300 so that it can rotate about a container body central axis AC that extends in the depth direction of the cooking container 300. As shown in Figure 3A etc., this rotating part 220 has a housing 221 connected to the base 210 (see also Figures 1 and 2), a cylindrical container rotation shaft 222 inserted into this housing 221, an oil seal 223 provided between the housing 221 and the container rotation shaft 222 and supporting the container rotation shaft 222 so that it can rotate freely relative to the housing 221, a first drive unit 224 that rotates the container rotation shaft 222, an agitator rotation shaft 225 that is inserted into the container rotation shaft 222 and arranged concentrically with the container rotation shaft 222 so that the two shafts rotate independently of each other, and a second drive unit 226 that rotates the agitator rotation shaft 225.
[0033] The container rotation shaft 222 has a flange 222a on the front end side, and this flange 222a is formed with a rotation preventing projection 222a1 that projects in the circumferential direction as shown in FIG.
[0034] The first drive unit 224 is composed of a first drive motor (not shown), a timing pulley 224a attached to the rear end of the container rotation shaft 222, and a timing belt 224b that is stretched between this timing pulley 224a and the first drive motor (not shown) and transmits the power of the first drive motor to the timing pulley 224a.
[0035] The stirring member rotation shaft 225 has a magnetized disk-shaped driving side ferromagnetic body 225a attached to the front end side. The driving-side ferromagnetic body 225a has north and south poles arranged alternately in the circumferential direction. That is, the driving ferromagnetic body 225a in this embodiment has four pairs of north and south poles. The axis of the stirring member rotation shaft 225 coincides with the axis of the container rotation shaft 222 .
[0036] The second drive unit 226 is composed of a second drive motor (not shown), a timing pulley 226a attached to the rear end of the stirring member rotation shaft 225, and a timing belt 226b that is stretched between this timing pulley 226a and the second drive motor (not shown) and transmits the power of the second drive motor to the timing pulley 226a.
[0037] <2.2. Cooking Containers> The cooking container 300 has a container body 310 for accommodating ingredients, and a stirring member 320 that is attached to the container body 310 and stirs the ingredients accommodated in the container body 310.
[0038] <2.2.1. Container body> As shown in FIG. 2, the container body 310 is formed from a disk-shaped bottom surface 311 and a cylindrical side surface 312 connected to the outer peripheral edge of the bottom surface 311.
[0039] As shown in FIG. 3A, the bottom surface 311 is formed from a circular magnetic region 311a made of a magnetic material and continuous with the side surface 312, and a disk-shaped non-magnetic member (non-magnetic region) 311b welded to the inner peripheral edge of the magnetic region 311a and structurally integrated with the magnetic region 311a. That is, the bottom surface 311 of the container body 310 of this embodiment includes a non-magnetic region.
[0040] As shown in FIG. 2, the non-magnetic member 311b has a cylindrical portion 311b1 that extends outward from the container body 310 (that is, toward the container holding unit 200). As shown in FIG. 2, the cylindrical portion 311b1 is formed with a rotation-preventing groove 311b2 that engages with the rotation-preventing protrusion 222a1 of the container holding unit 200. Therefore, when the anti-rotation protrusion 222a1 of the container rotation shaft 222 engages with the anti-rotation groove 311b2 formed in the container body 310 of the cooking container 300, the container rotation torque is transmitted from the container rotation shaft 222 to the container body 310, and the container body 310 rotates around the container body rotation axis CA shown in Figure 3A, etc. That is, the container rotation shaft 222 engages with the container body 310 of the cooking container 300 and transmits container rotation torque to the container body 310, causing the container body 310 to rotate about the container body central axis AC.
[0041] 2, 3A, and 3B, non-magnetic member 311b has cylindrical protrusion 311b3 that protrudes toward the inside of container body 310. As shown in FIG. The center of this protrusion 311b3 coincides with the central axis AC of the container body. As shown in FIG. 3B, spherical body 313 and spherical body fixing member 314 are held on the upper surface of convex portion 311b3, with a portion of spherical body 313 protruding from convex portion 311b3.
[0042] The side surface 312 is made of a magnetic material and is composed of a cylindrical surface 312a and a truncated conical inclined surface 312b connecting the cylindrical surface 312a and the bottom surface 311 as shown in FIG. When stirring and cooking ingredients contained in cooking container 300, inclined surface 312b is induction heated while being disposed opposite top plate 410 of container heating unit 400 at a distance from it, as shown in FIG. 4B. That is, the inclined surface 312 b on the side surface 312 of the container body 310 in this embodiment is made of a magnetic material and is induction-heated by the container heating unit 400 .
[0043] <2.2.2. Stirring member> As shown in FIGS. 2 and 5, the stirring member 320 is formed of a cylindrical base 321 attached to the container body 310 and a spatula 322 attached to the side surface of the base 321.
[0044] As shown in Figures 3A, 3B, 5, etc., the base 321 has a base main body 321a consisting of a peripheral side surface and a top surface, a magnetized, disk-shaped passive ferromagnetic body 321b inserted into the internal space 321a1 of the base main body 321a, a fixing screw 321c that fixes the passive ferromagnetic body 321b to the base main body 321a, a flat plate 321d that is inserted into the recess 321b1 of the passive ferromagnetic body 321b that inserts the protrusion 311b3 of the container body 310, a sealing member 321e that is interposed between the flat plate 321d and the fixing screw 321c, and an annular sliding bearing 321f that is press-fitted into the recess 321b1 of the passive ferromagnetic body 321b.
[0045] The passive ferromagnetic body 321b is positioned relative to the base body 321a when inserted into the base body 321a. The passive-side ferromagnetic body 321b has north and south poles arranged alternately in the circumferential direction, and has the same number of north and south poles as the driving-side ferromagnetic body 225a. The recess 321b1 of the passive ferromagnetic body 321b is formed in the center of the passive ferromagnetic body 321b. Therefore, when the recess 321b1 of the agitating member 320 is inserted into the protrusion 311b3 of the container body 310, the agitating member 320 rotates about the central axis AC of the container body.
[0046] The flat plate 321d is disk-shaped and is in point contact with the spherical body 313 of the container body 310 as shown in FIG. 3B. As shown in FIG. 3B, the cylindrical portion 311b1 of the container body 310 is inserted into the sliding bearing 321f. Therefore, as shown in FIGS. 3A and 3B, the stirring member 320 not only faces but also rotates and slides freely relative to the cylindrical portion 311b1 of the container body 310 via the sliding bearing 321f.
[0047] <2.3.Magnetic coupling mechanism> From the above explanation, the automatic cooking device 10 in this embodiment constitutes a magnetic coupling mechanism that transmits the rotational torque of the stirring member non-contact between the driving side ferromagnetic body 225a provided in the container holding unit 200 and the passive side ferromagnetic body 321b provided in the cooking container 300. Therefore, the container body 310 and the stirring member 320 of the cooking container 300 are independently rotatable about the container body central axis AC.
[0048] Furthermore, as shown in FIG. 4A, an attractive force MF is generated between the container holding unit 200 (driving ferromagnetic body 225a) and the stirring member 320 (passive ferromagnetic body 321b) due to the magnetic field. The stirring member 320 presses the container body 310 against the container holding unit 200 due to the attractive force MF generated by this magnetic field.
[0049] Furthermore, as shown in Figure 4B, the bottom surface 311 of the container body 310 is composed of a magnetic region 311a and a non-magnetic region 311b, so that the magnetic circuit MC1 formed between the driving side ferromagnetic body 225a of the container holding unit 200 and the passive side ferromagnetic body 321b of the stirring member 320 and the magnetic circuit MC2 formed between the side surface 312 (inclined surface 312b) of the container body 310 and the induction heating coil 420 of the container heating unit 400 are independent and separated.
[0050] <3. Stirring while cooking> Next, stirring cooking by the automatic cooking device 10, which makes use of the independent rotation of the container body 310 and the stirring member 320 of the cooking container 300, will be described with reference to FIGS. 6A and 6B. FIG. 6A is a schematic diagram showing a state in which ingredients have been placed in a cooking container, and FIG. 6B is a schematic diagram showing a state in which the ingredients are being stirred by a stirring member.
[0051] As shown in FIG. 6A, after the ingredient I is added to the container body 310, in this embodiment, the container body 310 rotates counterclockwise around the container body central axis AC, and the stirring member 320 rotates clockwise around the container body central axis AC. As a result, as shown in FIG. 6B, the spatula 322 of the stirring member 320 stirs the ingredients I placed in the container body 310. The rotation speed of the container body 310 and the rotation speed of the stirring member 320 can be freely changed and set according to the food to be cooked.
[0052] <4. Effects of the automatic cooking device 10> According to the automatic cooking apparatus 10 of one embodiment of the present invention described above, the container holding unit 200 has a container rotation shaft 222 that engages with the container body 310 of the cooking container 300 and transmits container rotation torque to the container body 310, causing the container body 310 to rotate about the container body central axis AC, and a stirring member rotation shaft 225 that rotates independently of the container rotation shaft 222. A magnetic coupling mechanism is formed between the stirring member rotation shaft 225 of the container holding unit 200 and the stirring member 320 of the cooking container 300, which transmits the stirring member rotation torque non-contact, allowing the stirring member 320 to rotate independently of the container body 310. Therefore, by rotating the stirring member 320 faster or slower than the container body 310, the stirring member 320 can be rotated independently of the container body 310, thereby more realistically and to a higher degree reproducing the well-trained stirring skills of a chef, and making it possible to cook a wide variety of dishes. Furthermore, by configuring a magnetic coupling mechanism that transmits the stirring member rotation torque non-contact between the stirring member rotation shaft 225 of the container holding unit 200 and the stirring member 320 of the cooking container 300, the bottom of the container body 310 has a simpler shape than when the stirring member 320 is fixed to the container body 310 with screws or the like, which eliminates ingredients remaining at the attachment point between the stirring member 320 and the container body 310 and also makes it easy to attach and detach the stirring member 320 to the container body 310 during maintenance.
[0053] Furthermore, the spherical body 313, which is in point contact with the recess 321b1 of the stirring member 320, is held on the upper surface of the protrusion 311b3 of the container body 310, and the bottom surface 11 of the container body 310 and the stirring member 320 are arranged facing each other at a distance, thereby reducing the sliding resistance between the container body 310 and the stirring member 320, and allowing the stirring member 320 to rotate more reliably and at higher speeds relative to the container body 310.
[0054] In addition, an anti-rotation protrusion 222a1 is formed on the container rotation shaft 222 of the container holding unit 200, and an anti-rotation groove 311b2 that engages with the anti-rotation protrusion 222a1 is formed on the container body 310 of the cooking container 300.Therefore, the cooking container 300 and the container holding unit 200 are positioned and held relative to each other simply by engaging the anti-rotation protrusion 222a1 with the anti-rotation groove 311b2, so that the container body rotation torque can be reliably transmitted from the container holding unit 200 to the container body 310 of the cooking container 300 with a simple structure.
[0055] Furthermore, since the container body 310 of the cooking container 300 is formed from a side surface 312 made of a magnetic material and inductively heated by the container heating unit 400, and a bottom surface 311 including a non-magnetic material region 311b, the magnetic circuit MC2 formed by the side surface 312 of the container body 310 and the container heating unit 400 is separate from the magnetic circuit formed within the magnetic coupling mechanism (magnetic circuit MC1 formed between the container holding unit 200 and the stirring member 320), so that it is possible to reliably achieve both rotation of the container body 310 and the stirring member 320 by the container holding unit 200 and induction heating by the container heating unit 400.
[0056] <Modification> Although an automatic cooking device according to one embodiment of the present invention has been described above, the automatic cooking device of the present invention is not limited to the automatic cooking device 10 of the above-described embodiment.
[0057] For example, in this embodiment, four pairs of north and south poles are arranged circumferentially on the driving side ferromagnetic body 225a of the container holding unit 200 and the passive side ferromagnetic body 321b of the cooking container 300, but the number of north and south poles can be any number as long as it is possible to form a magnetic coupling mechanism between the driving side ferromagnetic body 225a of the container holding unit 200 and the passive side ferromagnetic body 321b of the cooking container 300.
[0058] For example, in this embodiment, the container rotation shaft 222 of the container holding unit 200 is provided with the anti-rotation protrusion 222a1, and the container body 310 of the cooking container 300 is provided with the anti-rotation recessed groove 311b2. However, the container rotation shaft 222 of the container holding unit 200 may be provided with the anti-rotation recessed groove, and the container body 310 of the cooking container 300 may be provided with the anti-rotation protrusion.
