These expressions are based on the directions shown in the corresponding drawings and are merely descriptions of the directions in the states shown in the corresponding drawings. Please note that when the position and posture of the movable part change relative to the state of the drawing, the direction after the change may of course be different from the drawing drawn in the stationary state. In addition, regarding the rotation direction of the cooking container and the stirring component, expressions such as right rotation and left rotation are used. These expressions are all the rotation directions when observed from the open side of the cooking container.

[0057] [Implementation Method 1]

[0058] Reference Figures 1 to 16 An automatic cooking device according to Embodiment 1 of the present invention will be described.

[0059] <1. Overview of automatic cooking device 100>

[0060] First refer to Figure 1 to Figure 6 , an overview of the automatic cooking device 100 and a procedure for performing automatic cooking using the automatic cooking device 100 are described.

[0061] Figure 1 is a right perspective view of the automatic cooking device 100 according to the first embodiment of the present invention. Figure 2 yes Figure 1 The automatic cooking device 100 is shown in a rear left perspective view. Figure 1 and Figure 2 All of them show the cooking container 110 receiving food. Figure 1 and Figure 2 The food receiving posture shown in FIG. 1 is an example of a posture that is convenient for receiving food. In this embodiment, the cooking container 110 is not limited to taking this posture when supplying food. For example, as described later Figure 3 As shown, when the cooking container 110 is in the cooking posture, food materials may also be supplied to the cooking container 110 .

[0062] The automatic cooking device 100 includes a detachable cooking container 110, a cooking table 130, a container holding unit 140, a placing unit 150, a cleaning unit 160, and a control unit 170 (not shown). Power is supplied to the automatic cooking device 100 from a power supply line 180. An upper surface 131 and a container heating unit 132 are provided on the cooking table, and a dish serving as a placing container D is provided on the upper surface 131. In addition, an operation panel 171 is provided above the placing unit 150, and the operation panel 171 is used to input cooking operations to the automatic cooking device 100 and to display the operation status of the automatic cooking device 100. In addition, the cooking container 110 is a cylindrical container with a bottom, and a stirring member 120 is provided inside the cooking container 110.

[0063] The container holding unit 140 holds the cooking container 110 and has a function of rotating the cooking container 110 about a container rotation axis 114 (see Fig.11 ) The container rotation mechanism 144 (refer to Fig.11 A stirring member 120 is provided inside the cooking container 110. A stirring member driving mechanism 145 (see FIG. 1 ) for rotating the stirring member 120 is provided in the container holding unit 140. Fig.11 ). The rotation drive of the stirring member 120 by the stirring member driving mechanism 145 and the rotation rotation of the cooking container 110 by the container rotation mechanism 144 can be set independently. Therefore, when the rotation direction, rotation speed or stationary motion state of the cooking container 110 is the first motion state, the stirring member 120 can adopt a second motion state different from the first motion state of the cooking container 110. In addition, the stirring member driving mechanism 145 can make the motion state of the stirring member 120 become the second motion state different from the first motion state of the cooking container formed by the container rotation mechanism 144. For example, when the operating state of the cooking container 110 is clockwise rotation, counterclockwise rotation or stationary state, the stirring member driving mechanism 145 can make the operating state of the stirring member 120 become any state of clockwise rotation, counterclockwise rotation or stationary state.

[0064] In addition, the container holding unit 140 is configured to be driven to rotate relative to the placing unit 150. Therefore, the container holding unit 140 can change the posture of the cooking container 110 in the front-back direction and the up-down direction. Figure 1 The position of the cooking container 110 is tilted forward, and the container holding unit 140 can change the cooking container 110 to a cooking posture located at the container heating unit 132. Figure 1 The position of the cooking container 110 is tilted toward the rear side so that the opening of the cooking container is directed downward, and the container holding unit 140 can change the cooking container 110 to a cleaning posture located in the cleaning unit 160.

[0065] In addition, the placing unit 150 is configured to be driven to rotate by a placing position actuator 152 (not shown). Therefore, when the cooking container 110 is in the cooking position located at the container heating unit 132, the placing unit 150 is driven to rotate together with the container holding unit 140, thereby changing the position of the cooking container 110 to the placing position with the opening facing downward.

[0066] Figure 3 yes Figure 1 The left perspective view of the back of the automatic cooking device 100 in the cooking posture shown. Figure 1 The food receiving posture is tilted forward, and the container holding unit 140 can change the cooking container 110 to the cooking posture located in the container heating unit 132. The container heating unit 132 is provided with, for example, an IH heater 132a as a heating device, and the temperature of the heating device is controlled to a heating temperature corresponding to the cooking menu input from the operation panel 171. Here, the IH heater 132a is illustrated as the heating device of the container heating unit 132, but the present embodiment is not limited thereto. As long as the heating temperature can be controlled, any type of heating device can be used, such as a heater using a heating wire, a combustion heating device, etc.

[0067] Figure 4 yes Figure 1 The left perspective view of the automatic cooking device 100 in the serving posture is shown. Figure 3 The cooking posture drives the placing unit 150 and the container holding unit 140 to rotate forward together, thereby changing the posture of the cooking container 110 to the placing posture with the opening facing the state. In addition, at this time, the container heating unit 132 remains fixed to the cooking table 130 and does not move together with the placing unit 150. Since the container heating unit 132 can be kept fixed in the placing posture, there are advantages such as not having to drive a large part including the heating device, facilitating the wiring of the heating device, and facilitating the implementation of heat insulation measures for the heating device. As the placing posture actuator 152, various actuators such as a rotary motor, an electric linear actuator, a hydraulic or pneumatic actuator, etc. can be used. Furthermore, it is described here that the placing posture actuator 152 is used to rotate the placing unit 150, but this embodiment is not limited to this. For example, a rotation driving device such as a manual rod 151 can be provided to replace the placing posture actuator 152, or the placing posture actuator 152 and a rotation driving device such as a manual rod 151 can be used together. In addition, when the placing posture actuator 152 is provided, the manual lever 151 may be omitted.

[0068] Figure 5 yes Figure 1 The left perspective view of the back of the automatic cooking device 100 in the cleaning posture is shown. Figure 6 yes Figure 1 The left perspective view of the back of the automatic cooking device 100 during cleaning is shown in FIG. First, the automatic cooking device 100 is cleaned by using the holding posture actuator 152. Figure 4 The placing position makes the placing unit 150 and the container holding unit 140 return to the Figure 3 Secondly, from Figure 3 The cooking container 110 is tilted to the rear side and the opening is turned downward, so that the container holding unit 140 can change the cooking container 110 to the cleaning position located at the cleaning unit 160. At this time, the cleaning unit 160 moves to the retreat position below the cooking table 130 so as not to interfere with the cooking container 110. When the cooking container 110 is changed to the cleaning position, the cleaning unit 160 is controlled to move from Figure 5 The retreat position shown moves to Figure 6 Cleaning position shown.

[0069] Through the above Figure 1 to Figure 6 The automatic cooking device 100 of this embodiment can change the posture of the cooking container 110 so that it takes:

[0070] (1) an ingredient receiving posture in which the cooking container receives the ingredient;

[0071] (2) utilizing the container rotation mechanism to rotate the cooking container to cook the food;

[0072] (3) a holding posture in which the cooking container is tilted toward the holding container; and

[0073] (4) a cleaning posture in which the cooking container is cleaned with the opening side of the cooking container facing downward;

[0074] Therefore, the entire process of food reception, cooking, serving and cleaning can be properly automated.

[0075] Next, the sequence of automatic cooking using the automatic cooking device 100 is described. First, the cooking content to be performed using the automatic cooking device 100 is input from the operation panel 171. For example, the cooking content is input by selecting a cooking menu, a dish portion, a heating time, a recipe, etc. The operation panel 171 has a preset function, so a plurality of menus and cooking methods can be stored in advance. In addition, the heating time and stirring cooking can be set by input in the form of dialogue. Not only can the preset menu be set, but the heating time, the speed of the cooking container and the stirring component, the cleaning time, etc. can also be directly set.

[0076] When the cooking content is input from the operation panel 171, the cooking container 110 is controlled to be in the food receiving posture ( Figure 1 , Figure 2), so that the cooking container 110 receives the food. Next, the cooking container 110 is controlled to be in a cooking posture ( Figure 3 ), cooking is performed with corresponding heating time and stirring conditions according to the cooking content input from the operation panel 171. In addition, the cooking content can be stirring cooking, and heating is not necessary. For example, salads, chirashi sushi, bibimbap, etc. that do not require heating can also be cooked.

[0077] Secondly, control the cooking container 110 to be in the holding position ( Figure 4 ), the cooking container 110 and / or the stirring member 120 are driven to rotate in the placing posture, thereby automatically placing. Here, automatic placing is described, but the present embodiment is not limited thereto, and manual placing can also be performed as needed, or both automatic placing and manual placing can be used.

[0078] After placing, the cooking container 110 is controlled to be in a cleaning position ( Figure 5 , Figure 6 ), using the cleaning unit, using water flow to clean the cooking container 110. After cleaning, if the cooking content is input from the operation panel 171 again, or if the continuous cooking content has been input, the input from the operation panel 171 is skipped and the next cooking action is advanced.

[0080] Figure 7 yes Figure 1 The three-dimensional view of the cooking container 110 of the automatic cooking device 100 is shown. Figure 8 yes Figure 1 An elevational view of the stirring component 120 of the automatic cooking device 100 is shown. Figure 8 A is a stereogram, Figure 8 B is the top view. Figure 8 C is the left side view. Figure 8 D is the front view.

[0081] The stirring member 120 includes a base 120a, a straight portion 120b, and a curved portion 120c. On the other hand, the cooking container 110 includes a bottom portion 110a, an inclined portion 110b, and a side portion 110c. The shape of the stirring member is as follows: the base 120a matches the bottom portion 110a, the straight portion 120b matches the inclined portion 110b, and the curved portion 120c matches the side portion 110c. In addition, the base 120a and the straight portion 120b are in the same plane, and the curved portion 120c is curved in a top view and a front view.

[0084] The container holding unit 140 includes a posture control mechanism 141 and a container driving subunit 143. The posture control mechanism 141 includes a posture control motor 141a and a rotation driving arm 141b. The placing unit 150 includes a placing actuator 152 (not shown). The rotation driving arm 141b is driven by the placing actuator 152 to rotate around the rotation axis of the rotation driving arm 141. As the placing actuator 152, for example, a linear actuator or a rotation motor can be used. For example, the linear actuator is installed between the rotation driving arm 141b and the cooking table 130. In addition, for example, the rotation motor drives the rotation driving arm 141b to rotate around the rotation axis by direct drive, gear drive, belt drive, etc. The container driving subunit 143 includes a container rotation mechanism 144 and a stirring member driving mechanism 145. The posture of the cooking container 110 is controlled by the container holding unit 140 and the placing unit 150.

[0085] <3.1. Posture Control Mechanism 141>

[0086] The posture control mechanism 141 includes a rotation drive arm 141b and a posture control motor 141a mounted on the rotation drive arm 141b. The posture control motor 141a can control the angle of the cooking container 110 in the front-to-back direction and the up-down direction by rotationally driving the container drive subunit 143. Shaft insertion holes 143a and 143b are respectively provided at both ends of the container drive subunit 143 in the left-right direction. A driving shaft 141a1 of the posture control motor 141a is fixed in the left shaft insertion hole 143a. A shaft (not shown) protruding from the right rotation drive arm 141b is inserted into the right shaft insertion hole 143b. The posture of the container drive subunit 143 around the left-to-right axis of the two shaft insertion holes 143a and 143b is controlled by using the left and right pair of shaft insertion holes 143a and 143b, and the posture of the container drive subunit 143 in the front-to-back direction and the up-down direction is controlled by using the posture control motor 141a. As described above, the rotation driving arm 141b is driven by the placing actuator 152 to rotate around the rotation axis of the rotation driving arm 141. Thus, the posture of the cooking container 110 is controlled to be the food receiving posture, the cooking posture, the placing posture and the washing posture.

[0087] <3.2. Container rotation mechanism 144>

[0088] The stirring member rotating shaft 121 is concentrically arranged inside the hollow container rotating shaft 114. The stirring member rotating shaft 121 and the hollow container rotating shaft 114 are supported by the container driving subunit 143 so as to rotate freely relative to each other and to rotate freely separately. The container self-rotating mechanism 144 is configured to drive the container side driven wheel 144d connected to the hollow container rotating shaft 114 by the driving force of the container driving motor 144a via the container driving belt 144c. The container driving wheel 144b driving the container driving belt 144c is installed on the output shaft of the container driving motor 144a. The container driving wheel 144b is connected to the container rotating shaft 114, so that the container driving motor 144a can control the self-rotating motion of the cooking container via the container driving belt 144c. There is no particular limitation as the container driving motor 144a, and for example, a brushless motor can be used. In addition, there is no particular limitation as the container driving belt 144c, and for example, a belt made of rubber or polyurethane can be used.

[0089] <3.3. Stirring member driving mechanism 145 >

[0090] The stirring member driving mechanism 145 is configured to drive the stirring member side driven wheel 145d fixed on the stirring member driving shaft 145e by the driving force of the stirring member driving motor 145a via the stirring member driving belt 145c, and the stirring member driving shaft 145e is concentrically supported on the inner side of the hollow container rotating shaft 114 and connected to the stirring member rotating shaft 121. The stirring member driving wheel 145b driving the stirring member driving belt 145c is installed on the output shaft of the stirring member driving motor 145a. In addition, the stirring member driving mechanism 145 is equipped with an encoder 145m for detecting the rotation angle of the stirring member driving shaft 145e. The encoder 145m can detect the rotation speed and rotation position of the stirring member 120 by detecting the rotation information of the rotating plate 145k fixed below the stirring member side driven wheel 145d of the stirring member driving shaft 145e. Furthermore, the stirring member driving wheel 145b is connected to the stirring member rotating shaft 121, so the stirring member driving motor 145a can control the rotation speed and rotation position of the stirring member 120 via the stirring member driving belt 145c. The stirring member driving motor 145a is not particularly limited, and for example, a stepping motor can be used to facilitate positioning control. In addition, the stirring member driving belt 145c is not particularly limited, and for example, a belt made of rubber or polyurethane can be used.

[0091] <3.4. Container Rotation Shaft 114 and Stirring Member Rotation Shaft 121 >

[0092] As described above, the stirring member rotating shaft 121 is concentrically arranged inside the hollow container rotating shaft 114. The stirring member rotating shaft 121 and the hollow container rotating shaft 114 are axially supported by the container driving subunit 143 so as to be mutually rotatable and to be independently rotatable. Next, the structures of the container rotating shaft 114 and the stirring member rotating shaft 121 are described in detail.

[0093] The cooking container 110 is fixed to the upper end of the container rotation shaft 114. A bottom through hole for fixing the cooking container 110 to the container rotation shaft 114 is provided at the center of the bottom surface 110a of the cooking container 110. Inside the bottom through hole, the container inner fixing plate 111 is overlapped on the upper side of the container outer peripheral fixing plate 112, and the bottom surface 110a of the cooking container 110 is clamped by the container outer fixing plate 112 and the container inner fixing plate 111, and fixed by the container fixing screw 113. Here, an O-ring 114c is provided between the container rotation shaft 114, the container outer peripheral fixing plate 112, and the container inner fixing plate 111.

[0094] The lower part of the container rotating shaft 114 is supported by the container mounting mechanism 115 so as to be rotatable. The container mounting mechanism 115 includes a base 115b, a gripping portion 115c fixed to the base 115b, and a bearing support portion 115a fixed to the inner side of the base 115b by a screw 115d. A container bearing 116 is provided on the inner side of the bearing support portion 115a. The thrust receiving portion 114a of the container rotating shaft 114 slides in contact with the inner upper portion of the container bearing 116, forming a thrust bearing for the downward force. Below the container bearing 116, a thrust receiving ring 114b is provided on the outer side of the container rotating shaft 114. The thrust receiving ring 114b slides in contact with the inner lower portion of the container bearing 116, forming a thrust bearing for the upward force.

[0095] On the inner side of the container rotating shaft 114, the stirring member rotating shaft 121 is supported by the stirring member bearings 123a and 123b so as to be rotatable. The base 120a of the stirring member 120 is fixed to the stirring member mounting portion 121a at the upper end of the stirring member rotating shaft 121 by the stirring member fixing screw 122. The thrust bearing portion 121b of the stirring member rotating shaft 121 is in sliding contact with the inner upper side of the stirring member bearing 123a on the upper side, forming a thrust bearing for the downward force. An oil seal 124 is provided on the inner side of the container rotating shaft 114 above the thrust bearing portion 121b to prevent liquid from leaking to the inner side of the container rotating shaft 114. The stirring member rotating shaft connecting portion 125 which connects the stirring member rotating shaft 121 and the stirring member driving shaft 145e by shape combination is located below the stirring member bearing 123b on the lower side, and the lower surface of the stirring member bearing 123b on the lower side and the upper surface 125a of the stirring member rotating shaft connecting portion 125 constitute a thrust bearing for the upward force.

[0096] The container side driven wheel 144d is connected to the lower end of the container rotating shaft 114 by shape combination, thereby forming the container fixed shaft connecting part 117. The bearing support part 145g supporting the stirring drive bearing 145e is fixed to the container driving subunit 143 by screws. A thrust bearing 144g is provided at the lower end of the container side driven wheel 144d. The thrust receiving part 144f of the container side driven wheel 144d is in sliding contact with the thrust bearing 144g.

[0097] The container mounting mechanism 115 integrally supports the cooking container 110 and the stirring member 120 for rotation. The cooking container 110, the stirring member 120 and the container mounting mechanism 115 form an integral unit. The container mounting mechanism 115 is mounted and dismounted relative to the container driving subunit 143, thereby enabling the cooking container 110 to be loaded and unloaded relative to the automatic cooking device 100. The loading and unloading of the container rotating shaft 114 and the container side passive wheel 144d and the loading and unloading of the stirring member rotating shaft 121 and the stirring member driving shaft 145e are achieved by shape combination. That is, for example, mutually meshing concave and convex are respectively provided on the shafts to make them mesh with each other, thereby enabling them to be connected so as to transmit rotational force to each other. When the container mounting mechanism 115 is mounted on the container driving subunit 143, it is fixed by mounting screws 115e.

[0098] Bearings 145f and 145h are provided on the inner periphery of the container side driven wheel 144d. A stirring member drive shaft 145e is supported on the inner side of the bearings 145f and 145h. The lower surface 125b of the stirring member rotating shaft connecting portion 125 is in sliding contact with the upper surface of the bearing 145f. In addition, a thrust bearing portion 145j formed by expanding the diameter of the stirring member drive shaft 145e is provided above the stirring drive bearing 145i, and the upper and lower parts of the thrust bearing portion 145j are in sliding contact with the bearing 145h and the stirring drive bearing 145i respectively. A rotating plate 145k is installed at the lower end of the stirring member drive shaft 145e, and an encoder 145m is provided opposite to the rotating plate 145k.

[0099] With the above-described structure, the stirring member 120 can adopt a second motion state different from the first motion state of the cooking container 110 when the rotation direction, rotation speed or stationary motion state of the cooking container 110 is the first motion state. In addition, the stirring member driving mechanism 145 can make the motion state of the stirring member 120 the second motion state different from the first motion state of the cooking container 110 formed by the container rotation mechanism 144. For example, when the operation state of the cooking container 110 is right rotation, left rotation or stationary state, the stirring member driving mechanism 145 can make the operation state of the stirring member 120 any one of right rotation, left rotation or stationary state. In this way, the stirring member driving mechanism 145 can control the stirring member 120 independently of the rotation motion of the cooking container 110 performed by the container rotation mechanism 144. In addition, the stirring member driving mechanism 145 can grasp the rotation position and / or speed of the stirring member 120 and appropriately control the rotation position and / or speed of the stirring member 120 according to the cooking content input from the operation panel 171.

[0100] In addition, the cooking container 110 may not only be in a posture with the opening facing upward, but may also be in a posture with the opening facing downward, such as in a washing posture or a placing posture. According to the structure of the container rotating shaft 114 and the stirring member rotating shaft 121 as described above, no matter what posture the cooking container 110 is in, the thrust load and radial load generated by the cooking container 110 can be supported by the bearing mechanism, thereby appropriately supporting the cooking container 110.

[0101] <4. Cleaning unit 160>

[0102] Secondly, refer to Fig.12 and Fig.13 , the structure of the cleaning unit 160 is described. Fig.12 yes Figure 1 The cross-sectional view of the cleaning unit 160 of the automatic cooking device 100 is shown. Fig.13 yes Figure 1 The left side cross-sectional view of the cleaning unit 160 of the automatic cooking device 100 is shown.

[0103] The cleaning unit 160 has a plurality of nozzles 161 for cleaning the cooking container 110 by water flow. The inner surface of the cooking container 110 can be cleaned by the water flow sprayed from the plurality of nozzles. The water flow of the plurality of nozzles is controlled by a solenoid valve 166 (not shown). The solenoid valve 166 is used to control the switch of the water flow sprayed from each nozzle, and the solenoid valve 166 can also be used to control the water volume and water pressure of the water flow sprayed from each nozzle. The cleaning unit 160 is equipped with a water tank, and the water in the water tank is heated by a heater to make it warm water, and the warm water is sprayed from the nozzle, thereby making the cleaning water circulate to clean the cooking container. Depending on the degree of dirt, a cleaning agent can also be used. For rinsing, tap water can be used instead of circulating water. In addition, a rinse aid can also be used to facilitate drying.

[0104] The cleaning unit 160 is provided with a scraper pressing mechanism 162, a pressing mechanism 163, and a driving mechanism 164, which can press the scraper 162a against the cleaning cooking container 110. By making the scraper 162a elastically contact the cooking container 110 and rotating the cooking container 110, dirt inside the cooking container 110 can be scraped off. The structure for pressing the scraper 162a against the cooking container 110 will be described in detail.

[0105] <4.1. Scraper pressing mechanism 162>

[0106] The scraper pressing mechanism 162 includes a scraper 162a and a scraper pressing member 162b. The scraper 162a is a substantially square member having a bottom edge 162a1 and a side edge 162a2, and the bottom edge 162a1 and the side edge 162a2 correspond to the shapes of the bottom surface 110a and the inclined surface 110b of the cooking container 110, respectively. Therefore, when the scraper 162a is pressed against the inner side of the cooking container 110, the bottom edge 162a1 and the side edge 162a2 match the bottom surface 110a and the inclined surface 110b of the cooking container 110, respectively, and dirt can be scraped off everywhere.

[0107] The scraper pressing member 162b includes a scraper fixing portion 162b1, a curved portion 162b2, a pivot support portion 162b3, and an operating portion 162b5. The scraper 162a is fixed to the scraper fixing portion 162b1 in a posture where, for example, the bottom edge 162a1 and the side edge 162a2 are pressed against the bottom surface portion 110a and the inclined surface portion 110b of the cooking container 110, respectively.

[0108] The pivot support portion 162b3 is provided with a pivot hole 162b4, and the pivot 162c is inserted into the pivot hole, so that the scraper pressing member 162b can swing freely around the pivot 162c. The front end of the operating portion 162b5 is provided with an operating point 162b6 that receives a pressing force in the P direction from a pressing member 163a described later. When the operating point 162b6 is applied with a pressing force in the P direction, the scraper pressing member 162b swings in the Q direction around the pivot 162c, and the scraper 162a is pressed against the inner surface of the cooking container 110.

[0109] The scraper pressing member 162b is substantially U-shaped, and its shape and the position of the pivot hole form a balanced state such that due to the weight of the scraper pressing member 162b, the scraper 162a is oriented away from the inner surface of the cooking container 110. Therefore, when the P direction pressing force applied to the operating point 162b6 is released, the scraper pressing member 162b is pushed back to the operating point 162b6 by its own weight, and swings in the direction opposite to the P direction and the Q direction.

[0110] <4.2. Pressing mechanism 163>

[0111] The pressing mechanism 163 transmits the driving force from the driving mechanism 164 to the operating point 162 b 6 of the operating portion 162 b 5 of the scraper pressing mechanism 162 via the buffer member 163 b and the pressing member 163 a .

[0112] The pressing mechanism 163 includes a pressing member 163a, a buffer member 163b, a screw 163c, a spring member 163d, a spring seat member 163e, a screw 163f, an oil seal 163g and a sliding member 163h. The buffer member 163b is a rod-shaped member, and is provided with a screw hole 163b1, a sliding contact portion 163b2, a step portion 163b3, a small diameter portion 163b4 and a screw hole 163b5 in order from the top. The pressing member 163a is fixed to the screw hole 163b1 by means of a screw 163c. The sliding member 163h having a hollow cylindrical shape is fixed to the housing 164k, and the sliding contact portion 163b2 is in sliding contact with the inner side of the sliding member 163h, thereby causing the sliding contact portion 163b2 to slide in the up-down direction. A small diameter portion 163b4 is provided below the sliding contact portion 163b2, and a step portion 163b3 is provided between the sliding contact portion 163b2 and the small diameter portion 163b4. The small diameter portion 163b4 is inserted into the through hole 165a of the drive plate 165, so that the upper end of the drive plate 165 can abut against the step portion 163b3.

[0113] The spring seat component 163e is fixed to the screw hole 163b5 at the lower end of the small diameter portion 163b4 by the screw 163f. The cylindrical spring component 163d is concentrically arranged on the outer periphery of the small diameter portion. In a compressed state, the lower end of the spring component 163d elastically contacts the spring seat component 163e, and the upper end elastically contacts the drive plate 165. As a result, the drive plate 165 elastically contacts the step portion 163b3 by the pressing force of the spring component 163d, and in this state, the driving force of the drive plate 165 is transmitted to the buffer component 163b.

[0114] The driving plate 165 is driven in the vertical direction by the driving mechanism 164 described later. The driving plate 165 is pressed against the step portion 163b3 by the elastic force of the spring member 163d, so that the buffer member 163b also slides in the vertical direction as the driving plate 165 moves up and down. Thus, the driving force generated by the driving mechanism 164 is transmitted to the pressing member 163a via the driving plate 165 and the buffer member 163b.

[0115] When the scraper 162a is pressed against the inner surface of the cooking container 110, the cooking container 110 is driven to rotate, and the scraper 162a is used to scrape off the dirt attached to the inner surface of the cooking container 110. In the above operation, a reaction force is sometimes generated to the force in the Q direction that presses the scraper 162a against the inner surface of the cooking container 110. The reaction force is applied to the buffer member 163b as a force (upward force) in the opposite direction to the P direction from the operating point 162b6 toward the pressing member 163a. ​​Here, when the reaction force is large, the driving plate 165 will resist the elastic force of the spring member 163d and move downward from the step portion 163b3. As a result, the buffer member 163b has a buffering function, so that the scraper 162a can be elastically contacted with the inner surface of the cooking container 110.

[0116] <4.3. Driving mechanism 164>

[0117] The driving mechanism 164 drives the driving plate 165 , and the driving force is transmitted to the scraper pressing mechanism 162 via the pressing mechanism 163 .

[0118] The driving mechanism 164 includes a scraper driving motor 164a. The rotation of the scraper driving motor 164a is transmitted to the driving component 164d via the motor driving shaft 164b and the shaft connecting portion 164c. The driving component 164d is a rod-shaped component and includes a screw portion 164d1. The driving component 164d is supported by a bearing 164e on the upper side and a bearing 164j on the lower side. The screw portion 164d1 is engaged with the female thread component 164g. The upper end of the female thread component 164g is fixed to the driving plate 165 by a fixing screw 164h. The shape of the driving plate 165 corresponds to the inner surface of the housing 164k, so the female thread component 164g does not rotate. As a result, the female thread component 164g is driven in the up and down directions in accordance with the rotation of the scraper driving motor 164a, and the driving force is transmitted to the pressing mechanism 163 via the driving plate 165. The range in which the female screw member 164g is driven is limited by an upper stopper 164f provided above the drive plate 165 and a lower stopper 164i provided below the female screw member 164g.

[0119] As described above, the cleaning unit 160 is provided with the scraper pressing mechanism 162, the pressing mechanism 163 and the driving mechanism 164, and the scraper 162a can be pressed against the cooking container 110 being cleaned. During cleaning, when the cooking container 110 is rotated while being pressed against the scraper 162a, the dirt on the inner surface of the cooking container 110 can be scraped off by the scraper 162a while being cleaned by the water flow. Sometimes, after cooking with high heat, the inner surface of the cooking container 110 may generate burnt dirt, and by using the scraper 162a to scrape off the dirt on the inner surface of the cooking container 110, the cooking container 110 can be cleaned more appropriately even when burnt dirt is generated. In addition, when the scraper 162a is pressed against the inner surface of the cooking container 110, if the pressing force is too strong, there is a risk of causing an adverse situation, such as applying an excessive load to the container rotation mechanism 144 or damaging the inner surface of the cooking container 110. Therefore, by using a buffer component 163b in the pressing mechanism 163, the scraper 162a is elastically contacted with the inner surface of the cooking container 110, and the scraper 162a is always pressed against the inner surface of the cooking container 110 with an appropriate pressing force, which can help improve the cleaning effect and prevent adverse situations.

[0120] <5. Control unit 170 >

[0121] Secondly, refer to Fig.14 , the control unit 170 is described. Fig.14 yes Figure 1 The system configuration diagram of the automatic cooking device 100 is shown.

[0122] The control unit 170 of the automatic cooking device 100 includes an operation panel 171, a cooking control command unit 172, a posture control unit 173, a heating control unit 174, a container rotation control unit 175, a stirring member rotation control unit 176, and a washing control unit 177. The cooking control command unit 172 is connected to each of the control units 173 to 177 and the operation panel 171 so as to control the automatic cooking device 100 to perform cooking according to the cooking content input from the operation panel 171.

[0123] The cooking control instruction unit 172 is connected to other automatic cooking devices 100A to 100N and a management server 179 via an external network. The management server 179 may be a cloud server, for example. The automatic cooking device 100 manages cooking menu information, cooking control information, maintenance information, and the like through the management server 179.

[0124] The cooking content input from the operation panel 171 is sent to the cooking control command unit 172. In addition, the cooking status information and the like can be sent from the cooking control command unit 172 to the operation panel 171, and the information can be displayed on the operation panel 171. The posture control unit 173 controls the posture of the cooking container 110 by controlling the drive motor 141a of the posture control mechanism 141 and the placing posture actuator 152 of the placing unit 150. The heating control unit 174 controls the IH heater 132a of the container heating unit 132 to control the heating state such as the heating temperature and heating time of the cooking container 110. The container rotation control unit 175 controls the container drive motor 144a of the container rotation mechanism 144 to control the rotation direction and rotation speed of the cooking container 110. The stirring member rotation control unit 176 controls the stirring member drive motor 145a of the stirring member drive mechanism 145 to control the rotation position, rotation direction, rotation speed, etc. of the stirring member 120.

[0125] The stirring member rotation control unit 176 can control the position and speed of the stirring member 120 according to the position and speed information of the stirring member 120. For example, when the cooking container 110 is in the cooking posture, the stirring state of the food can be controlled by controlling the rotation direction and rotation speed of the stirring member 120. In addition, for example, when the cooking container 110 is in the cleaning posture, the stirring member 120 can be positioned and controlled so as to be at a rotation angle that does not interfere with the scraper 162a of the cleaning unit 160. In addition, for example, when the cooking container 110 is in the placing posture, the placing state can be controlled by controlling the rotation position, rotation direction and rotation speed of the stirring member 120.

[0126] The cleaning control unit 177 controls the electromagnetic valve 166 and the scraper driving motor 164a of the cleaning unit 160. The cleaning control unit 177 controls the on / off, water volume, water pressure, etc. of the water flow sprayed from each nozzle 161 by controlling the electromagnetic valve 166. In addition, the cleaning control unit 177 controls the scraper driving motor 164a to control the state in which the scraper 162a is pressed against the inner surface of the cooking container 110 to scrape off the dirt on the inner surface of the cooking container 110.

[0127] The control units 173 to 177 of the control unit 170 can be controlled in conjunction with each other according to the cooking command from the cooking control command unit 172. For example, when the cooking container 110 is in the cooking posture, the heating control unit 174, the container rotation control unit 175, and the stirring member rotation control unit 176 are controlled in conjunction so that the heating state and the stirring state of the food materials become appropriate states corresponding to the cooking content input from the operation panel 171. In addition, for example, when the cooking container 110 is in the washing posture, the stirring member 120 is positioned so as to be at a rotation angle that does not interfere with the scraper 162a, and the container rotation control unit 175, the stirring member rotation control unit 176, and the washing control unit 177 are controlled in conjunction to control the pressure of the scraper 162a, the rotation of the cooking container 110, the water flow, etc. In addition, for example, when the cooking container 110 is in the placing posture, the container rotation control unit 175 and the stirring member rotation control unit 176 are controlled in linkage, so that the dish cooked by the cooking container 110 is properly placed in the placing container D by using the stirring member 120. In addition, for example, the posture control of the cooking container 110 needs to be synchronized with the control of each control unit 174 to 177, so the posture control unit 173 and each control unit 174 to 177 are controlled in linkage.

[0128] <6. Cooking Examples>

[0129] Secondly, refer to Fig.15 and Fig.16 , a cooking example performed using the automatic cooking device 100 of this embodiment is described. Fig.15 yes Figure 1 The first cooking example of the automatic cooking device 100 shown in FIG. Fig.16 yes Figure 1 The second cooking example of the automatic cooking device 100 is shown.

[0130] Fig.15The first cooking example shown is an example of cooking stir-fried vegetables. Because a high flame is used for cooking, the cooking container 110 must be rotated while stirring the food to prevent it from burning. To this end, the cooking container 110 is rotated counterclockwise, and the stirring member 120 is also rotated counterclockwise. The rotation speed at this time is, for example, about 20 to 30 rpm, but there is no particular limitation. In this embodiment, the shape of the stirring member 120 is designed so that the food is stirred when the stirring member 120 rotates counterclockwise. Fig.15 As shown, by rotating the stirring member 120 counterclockwise (forward), the stirring member 120 stirs the food along the inner surface shape of the cooking container 110. When the cooking container 110 and the stirring member 120 rotate counterclockwise, it is easy to stir the food by the stirring member 120, so it is easy to stir the food.

[0131] In addition, in the cooking posture, the cooking container 110 is heated from the side by the container heating unit 132, and in the first cooking example, the cooking container 110 is rotated counterclockwise, so the part where the food contacts the cooking container 110 is constantly changing, so it is possible to prevent the food from being scorched on the inner surface of the cooking container 110 and to properly heat the food. For example, by setting the rotation speed of the cooking container 110 to be slightly faster (e.g., about 1 to 3 rpm) than the rotation speed of the stirring member 120, the part where the food contacts the cooking container 110 can be constantly changing, so it is easier to prevent scorching.

[0132] In the case of stir-fried vegetables in the first cooking example, the cooking vessel 110 and the stirring member 120 are rotated counterclockwise together. However, when cooking ingredients with a high viscosity, for example, the cooking vessel 110 is rotated clockwise and the stirring member is rotated counterclockwise, thereby achieving an effect of preventing the ingredients from being burnt.

[0133] Fig.16 The second cooking example shown is an example of cooking fried rice. In the second cooking example, cooking is performed using the following two modes: a forward rotation mode and a reverse rotation mode:

[0134] (1) Forward rotation mode is Fig.15 Similarly, the cooking container 110 is rotated counterclockwise, and the stirring member 120 is also rotated counterclockwise.

[0135] (2) The reverse rotation mode is to rotate the cooking container 110 counterclockwise and the stirring member 120 clockwise.

[0136] When cooking fried rice, it is required to achieve the same cooking action as the chef shaking the pot, so that the rice grains are fried clearly. To this end, by setting the time period for cooking in the reverse rotation mode, the chef's shaking of the pot can be reproduced. Furthermore, the following time periods of the right rotation mode can also be set:

[0137] (3) The clockwise rotation mode causes the cooking container 110 to rotate clockwise, and also causes the stirring member 120 to rotate clockwise.

[0138] The right-hand rotation mode helps to reproduce the action of shaking the pot more greatly, so in the second cooking example, the right-hand rotation mode period is introduced to reproduce the chef's diverse pot operation skills. In addition, the reverse rotation mode and the right-hand rotation mode reduce the contact time between the stirring member and the food, so for example, it is also possible to reproduce the mixing method of cut and mixed rice when making sushi rice, which is also more effective when cooking sushi rice, chirashi, bibimbap, etc. In addition, in the second cooking example, the rotation speed is set to about 60 rpm, but there is no special limitation.

[0139] In the automatic cooking device of this embodiment, the rotation directions and rotation speeds of the cooking container 110 and the stirring member 120 may be arbitrarily combined, for example, the following combinations may be used.

[0140] (a) The cooking container 110 rotates counterclockwise, and the stirring member 120 rotates counterclockwise.

[0141] (b) The cooking container 110 rotates clockwise and the stirring member 120 rotates counterclockwise.

[0142] (c) The cooking container 110 rotates left and the stirring member 120 rotates right

[0143] (b) The cooking container 110 rotates clockwise, and the stirring member 120 rotates clockwise.

[0144] (e) The cooking container 110 and the stirring member 120 are at the same speed

[0145] (f) The speed of the cooking container 110 is higher than that of the stirring member 120.

[0146] (g) The speed of the cooking container 110 is lower than that of the stirring member 120.

[0147] (h) The cooking container 110 rotates clockwise and the stirring member 120 stops.

[0148] (i) The cooking container 110 rotates counterclockwise and the stirring member 120 stops.

[0149] (j) The cooking container 110 stops and the stirring member 120 rotates clockwise.

[0150] (k) The cooking container 110 stops and the stirring member 120 rotates counterclockwise.

[0151] (l) The cooking container 110 stops, and the stirring member 120 stops.

[0152] By combining the above-mentioned actions (a) to (l), various stirring cooking can be set. Therefore, according to the automatic cooking device of this embodiment, stirring cooking can be reproduced, such as reproducing the cooking skills of a chef.

[0153] [Implementation Method 2]

[0154] Reference Figures 17 to 20 An automatic cooking device according to a second embodiment of the present invention will be described. The same components as those in the first embodiment are denoted by the same reference numerals and their description will be omitted. Fig.17 1 is a perspective view of a cooking container 110 of an automatic cooking device 100 according to Embodiment 2 of the present invention. In this embodiment, a scraper 126 is attached to the stirring member 120 to perform a more appropriate placing operation.

[0155] The scraping member 126 includes a base 126a, an inclined portion 126b and a scraping portion 126c. The mounting member 128 is fixed to the base 126a by a screw 128a. On the other hand, a stirring member side fixing portion 127 is installed on the straight portion 120b of the stirring member 120. The mounting member 128 is installed on the stirring member side fixing portion 127 by a hinge 129 so that the scraping member 126 can rotate freely relative to the stirring member 120.

[0156] The scraping member 126 rotates in the same direction as the stirring member 120 along with the stirring member 120. When the stirring member rotates to the left (forward direction), the scraping member 126 can move by its own weight, but when the stirring member is in the forward direction, the scraping member 126 is in a state where it does not function to scrape the food from the cooking container 110. On the other hand, when the stirring member rotates to the right (reverse direction), the scraping member 126 not only moves by its own weight, but also rotates in a state where the outer side surfaces of the inclined portion 126b and the scraping portion 126c are respectively in contact with the inclined surface portion 110b and the side portion 110c of the cooking container 110, so that the food in the cooking container 110 is pushed out by the scraping portion 126c and scraped into the storage container D. At this time, the angle between the inclined portion 126b and the straight portion 120b is determined by the position where the scraper portion 126c meets the side portion 110c, the position where the hinge 129 is installed on the straight portion 120b, and the position where the straight portion 120b meets the inclined surface portion 110b.

[0157] In addition, when the stirring member 120 is kept stationary and the cooking container is only rotated to the left, the cooking container 110 also rotates in a state in which the outer side surfaces of the inclined portion 126b and the scraping portion 126c are respectively in contact with the inclined surface portion 110b and the side portion 110c of the cooking container 110, so that the dishes in the cooking container 110 are pushed out by the scraping portion 126c and scraped into the containing container D.

[0158] Secondly, refer to Figures 18 to 20 , a cooking example of this embodiment is described.

[0159] Fig.18 yes Fig.17The cooking example of the automatic cooking device 100 shown in FIG. Fig.19 yes Fig.17 The first placing operation example of the automatic cooking device 100 shown in FIG. Fig. 20 yes Fig.17 The second placing operation example of the automatic cooking device 100 is shown.

[0160] Fig.18 This is a cooking example of stir-frying using a stirring member 120 equipped with a scraping member 126. The cooking container 110 is set to rotate counterclockwise, and the stirring member 120 is also set to rotate counterclockwise. In this case, similarly to the first cooking example of the first embodiment, by rotating the stirring member 120 counterclockwise (forward), the stirring member 120 stirs the food along the inner surface shape of the cooking container 110. When the cooking container 110 and the stirring member 120 rotate counterclockwise, it is easy to stir the food using the stirring member 120, so it is easy to stir the food. When the stirring member 120 is rotated counterclockwise, the scraping member 126 swings due to its own weight, but it does not affect the stirring state of the food.

[0161] Fig.19 This is the first example of placing food in a case where the scraper 126 is driven to rotate for placing food. The cooking container 110 is set to rotate counterclockwise, and the stirring member 120 is set to rotate clockwise. As described above, when the stirring member 120 is rotated clockwise (reversely), the scraper 126 rotates at an angle determined by the scraper 126c, the hinge 129, and the straight portion 12b, with the inclined portion 126b and the outer side surface of the scraper 126c respectively contacting the inclined surface portion 110b and the side portion 110c of the cooking container 110, so that the food in the cooking container 110 is pushed out by the scraper 126c and scraped into the placing container D. In the first example of placing food, when placing food, the stirring member 120 is rotated clockwise (not particularly limited, for example, about 10 to 20 rpm) while the cooking container 110 is rotated counterclockwise at a low speed (not particularly limited, for example, about 1 to 3 rpm). In the first example of placing food, placing food can be performed without rotating the cooking container 110. However, if the food is placed while the cooking container 110 is stationary, it may be impossible to scrape out the food adsorbed on the inner surface of the cooking container 110. Therefore, when the viscosity of the food is particularly high, it is preferred to rotate the cooking container 110 counterclockwise while placing the food.

[0162] Fig. 20This is a second example of placing the food after the scraper 126 is stopped. The cooking container 110 is set to rotate counterclockwise (not particularly limited, for example, about 10 to 20 rpm), and the stirring member 120 is stopped. In this case, a force of relative rotation in the clockwise direction relative to the circumference of the cooking container 110 acts on the scraper 126, so that the outer side surfaces of the inclined portion 126b and the scraper 126c are respectively in contact with the inclined surface portion 110b and the side portion 110c of the cooking container 110 at an angle determined by the scraper 126c, the hinge 129, and the straight portion 12b. Therefore, the food in the cooking container 110 is pushed out by the scraper 126c and scraped into the placing container D. In addition, in the second example of placing the food, the cooking container 110 is rotated counterclockwise, but it is not rotated counterclockwise all the time, but a period of time in which it rotates clockwise from time to time is set, so that the food can be scraped out without the food being adsorbed on the entire circumference of the cooking container 110.

[0163] <Example of Change>

[0164] The above-mentioned embodiment illustrates an automatic cooking device for realizing the technical concept of the present invention. The present invention is not limited to them and can also be applied to other embodiments such as an embodiment obtained by adding changes to the present embodiment and an embodiment combining the various technologies described in the present embodiment.

[0165] For example, in the above embodiment, the stirring member is provided on the bottom surface of the cooking container, but the stirring member does not have to be provided on the bottom surface of the cooking container, and the stirring member may be inserted from the opening surface side. In addition, it is described that the cooking container 110 has the bottom surface 110a, the inclined surface 110b, and the side surface 110c, but the cooking container 110 may have any shape as long as it is a bottomed cylindrical shape. For example, the bottom surface 110a, the inclined surface 110b, and the side surface 110c may have a hemispherical shape or a conical shape.

[0166] For example, the arrangement of each device in the embodiment of the present invention is not limited to the drawings, and can be interchanged left and right or front and back. For example, the operation panel 171, the power supply line 180, etc. can be arbitrarily arranged and are not limited to the drawings.

[0167] For example, in the above embodiment, the cleaning unit 160 cleans the cooking container 110 with cleaning water, but the cleaning method of the inner surface of the cooking container 110 is not limited to water washing. In addition, in the above embodiment, the automatic cooking device 100 includes the cleaning unit 160, and the cleaning unit 160 may be separated from the automatic cooking device 100. When the cleaning unit 160 is separated from the automatic cooking device 100, the automatic cooking device 100 and the cleaning unit 160 are controlled by a control device that controls the operation of the automatic cooking device 100 and the operation of the cleaning unit 160, respectively.

[0168] For example, in the above embodiment, the cooking container 110 is rotationally driven while the scraper 162a is pressed against the inner surface of the cooking container 110. However, a driving mechanism may be provided so that the scraper 162a reciprocates along the inner surface of the cooking container 110 while being pressed against the cooking container 110. In this case, dirt on the inner side of the cooking container 110 can be scraped off by driving only the scraper 162a or by both the rotational driving of the cooking container 110 and the driving of the scraper 162a.

[0169] For example, in the above-mentioned embodiment, the heating device of the container heating portion 132 is not limited to the IH heater 132a, and any heating device can be applied as long as the temperature can be controlled, such as a radiation heater that heats the cooking container by heating with an electric heating wire, or a packaged heater.

[0170] For example, in the above-mentioned embodiment, the control unit 170 automatically performs all the controls of the automatic cooking device 100 according to the cooking content based on the input from the operation panel 171, and part of the control performed by the control unit 170 may be replaced by an input instruction from the operator. Furthermore, part of the cooking action may be performed manually or semi-automatically instead of automatically performing all the cooking actions performed by the automatic cooking device 100. For example, for the purpose of aesthetic design, the dish may be placed manually by the operator. In addition, the control unit 170 may not be connected to the external network 178, but the automatic cooking device 100 may be controlled independently.
