[0010] Preferred embodiments of the cooking device of the present invention will be described below with reference to the accompanying drawings. The embodiments described below do not limit the content of the present invention as defined in the claims. Furthermore, not all of the configurations described below are necessarily essential requirements of the present invention.

[0011] 1 to 4 show an embodiment in which a cooking device 1 is applied to an oven range, which is common to the present invention. First, the configuration of cooking device 1 will be described with reference to FIGS. 1 to 3. Cooking device 1 of the present invention has a cooking function using oven heating, which heats food S to be cooked using hot air supplied into cooking chamber 15 or food S contained in container C, a cooking function using grill heating, which heats food S to be cooked using heat from a heater or food S contained in container C, and a cooking function using range heating, which irradiates food S to be cooked or food S contained in container C with microwaves to heat and cook the food S. Cooking device 1 has a main body 2 formed in a substantially rectangular box shape and a door 3 that can be opened and closed and is provided to cover substantially the entire front of main body 2. Main body 2 also has a metal cabinet 4 as a member that covers the outer shell of cooking device 1, which is the product.

[0012] The top of the door 3 is provided with a handle 5 for opening and closing the vertically opening door 3, and the right side of the door 3 is provided with an operation panel 6 for display, notification, and operation. The operation panel 6 is provided with a display means 7 that displays the cooking settings and progress status, and an operation means 8 that enables various operation inputs related to heating and cooking. The operation means 8 is composed of a cooking start instruction means 8a, a cancellation instruction means 8b, and an electrostatic touch panel 8c that is provided on the surface of the display means 7, and therefore the operation means 8 functions as a selection means for selecting heating conditions.

[0013] The display means 7 is a backlit display that displays all information related to cooking, such as the type of heating, the name of the dish, the heating time, the temperature, and a photo of the cooking, in color using letters, numbers, symbols, photos, etc. In this case, it is composed of a liquid crystal display that uses TFTs (thin film transistors) as switching elements, but other display devices such as organic EL may also be used, and it is not limited to color display but may also be black and white display.

[0014] The cooking start instruction means 8a and the cancellation instruction means 8b of this embodiment are provided as push operation units that accept push operations from the user. The cooking start instruction means 8a is pushed to start cooking, and the cancellation instruction means 8b is pushed to stop cooking midway or to cancel an operation or setting. The touch panel 8c is provided on the top surface, which becomes the surface of the display means 7, and allows the user to select one of multiple display elements displayed on the display means 7 by touching it with a fingertip.

[0015] Disposed below the bottom wall 15a of the cooking chamber 15 is a microwave heating means 25 that supplies microwaves, which are radio waves, into the cooking chamber 15 and irradiates the microwaves onto the food S to be cooked or the food S contained in a container C to heat it in the microwave oven. The microwave heating means 25 is composed of a magnetron 26 that generates microwaves, an antenna 28 that receives the microwaves guided from the magnetron 26 to the cooking chamber 15 via a waveguide 27 and radiates the microwaves into the cooking chamber 15, an antenna motor 29 such as an AC motor that rotates the antenna 28 horizontally around an upright axis, and an inverter 30 (see Figure 4) that serves as the drive power source for the magnetron 26. Reference numeral 31 denotes a microswitch that detects the origin position of the antenna 28.

[0016] A grill heater 23 is provided on the ceiling wall 15b of the cooking chamber 15. In this embodiment, the grill heater 23 is configured to perform grill heating, which heats the food S in the cooking chamber 15 or the food S contained in the container C with radiant heat.

[0017] A rear wall 15c of cooking chamber 15 has an intake port (not shown here) at its center that takes in air from cooking chamber 15, and multiple supply holes 33 are provided above, below, left, and right of the intake port to supply hot air into cooking chamber 15. Behind rear wall 15c is disposed a hot air unit 34 that includes a hot air heater 35 for heating the air, a hot air fan 36 that sends and circulates the air heated by hot air heater 35 into cooking chamber 15, a hot air motor 37 (see FIG. 4) that drives hot air fan 36 to rotate in a predetermined direction, and a transmission mechanism 40 such as pulleys for the hot air motor and hot air fan that transmit the driving force from hot air motor 37 to hot air fan 36 and a belt connecting these pulleys. In the present invention, the hot air fan 36 is rotated and air heated by the hot air heater 35 is supplied into the cooking chamber 15, thereby performing hot air convection heating (oven heating) on ​​the food S in the cooking chamber 15 or the food S contained in the container C.

[0018] The left side walls 15d and 15e of the cooking chamber 15 are provided with a pair of shelf supports 22, one on each side, one on top of the other, for storing and holding metal square plates 21 in a suspended state inside the cooking chamber 15. While FIG. 2 shows a square plate 21 placed on the lower shelf support 22 inside the cooking chamber 15 with a container C placed on the square plate 21, depending on the cooking method, the square plate 21 may be placed only on the upper shelf support 22, or two square plates 21 may be placed on each of the upper and lower shelf supports 22. Alternatively, a separate accessory such as a grill (not shown) may be stored and held instead of the square plate 21. Furthermore, in microwave heating using the microwave generator 25 described above, the food S to be cooked can be placed in a microwaveable container C inside the cooking chamber 15 and cooked without placing the square plate 21, grill, or the like inside the cooking chamber 15.

[0019] Additionally, a temperature detection means 47 is incorporated above the left side wall 15d of the cooking chamber 15, and a food temperature detection means 48 is incorporated above the right side wall 15e of the cooking chamber 15. The temperature detection means 47 detects the temperature inside the cooking chamber 15 and is composed of, for example, a thermistor. The food temperature detection means 48 is composed of an infrared sensor (not shown) equipped with a swing mechanism, and by detecting the temperature distribution inside the cooking chamber 15, it is possible to detect the temperature of the food placed therein without contact.

[0020] Fig. 4 shows the main electrical configuration of the cooking appliance 1. In the figure, reference numeral 51 denotes control means constituted by a microcomputer, and as is well known, this control means 51 includes a CPU as a processing means, storage means 52 such as a memory, a timer as a timekeeping means, input / output devices, etc.

[0021] The input port of the control means 51 is electrically connected to the above-mentioned operation means 8, temperature detection means 47, and food temperature detection means 48, as well as hot air motor rotation detection means 38 that detects the rotation of the hot air motor 37 incorporated in the hot air unit 34, and antenna position detection means 39 equipped with a microswitch 31. The output port of the control means 51 is electrically connected to the above-mentioned display means 7, grill heater 23, microwave heating means 25 including antenna motor 29 and inverter 30, and hot air unit 34 including hot air heater 35, hot air fan 36, and hot air motor 37.

[0022] Control means 51 receives operation signals from operation means 8 and detection signals from temperature detection means 47, food temperature detection means 48, hot air motor rotation detection means 38, and antenna position detection means 39, and outputs drive control signals to grill heater 23, microwave heating means 25, and hot air unit 34, which serve as heating means, at predetermined timing based on the timing of the timer, and also outputs display control signals to display means 7. These functions are realized by control means 51 reading a program recorded in storage means 52, which serves as a storage medium, and particularly in the present invention, control means 51 is provided with a program that causes it to function mainly as heating control means 53 and display control means 54.

[0023] Heating control means 53 mainly controls the operation of each part involved in the heating and cooking of food S placed in cooking chamber 15. When it receives an operation signal associated with the operation of operating means 8, it sends control signals to grill heater 23, microwave heating means 25, and hot air unit 34 in accordance with the operation signal, thereby controlling the heating and cooking of food S in cooking chamber 15 and food S contained in container C. In the present invention, cooking information for all menus that can be cooked by cooking appliance 1 is stored in storage means 52, and when an operation to start cooking is performed from operating means 8 for one menu selected from storage means 52, heating control means 53 heats and cooks food S in a predetermined procedure in accordance with the cooking information for the selected menu.

[0024] For example, when a menu for oven heating is selected, heating control means 53 receives a detection signal from temperature detection means 47 and outputs a drive control signal to hot air unit 34, controlling the energization and de-energization of hot air heater 35 and hot air motor 37 so that cooking chamber 15 is heated to the set temperature. As a result, the rotational force generated in hot air motor 37 is transmitted to hot air fan 36, causing hot air fan 36 to rotate in one direction inside hot air unit 34, and sending air sucked into hot air unit 21 from cooking chamber 15 through the intake port toward energized hot air heater 35. The heated air is then supplied as hot air to cooking chamber 15 through multiple supply holes 33, thereby heating food S in cooking chamber 15 by hot air convection heating.

[0025] Furthermore, when a menu for microwave cooking is selected, heating control means 53 receives a detection signal from food temperature detection means 48, outputs a drive control signal to microwave heating means 25 so that food S is heated to the set temperature, and sends appropriate control signals to antenna motor 29 and inverter 30. This causes magnetron 26 and antenna 28 of microwave heating means 25 to operate, and microwaves generated from the surface of rotating antenna 28 are supplied into cooking chamber 15, heating food S in cooking chamber 15 and food S contained in container C at high frequency.

[0026] When a menu for grill cooking is selected, the heating control means 53 receives a detection signal from the temperature detection means 47 and controls the on / off of the grill heater 23 so that the cooking chamber 15 is heated to the set temperature, and the food S to be cooked in the cooking chamber 15 is grill-heated from above. [Example]

[0027] 5 to 8 show the configuration of a first embodiment of the cooking appliance 1 of the present invention. This embodiment is provided with a container lid 62 as stirring means having a blade 68 that rotates for stirring and a transmission unit 69 that transmits power to the blade 68. By connecting the transmission unit 69 of the container C' to a connection unit 83 of the cooking chamber 15, the blade 68 in the container C' can be rotated while the container C' is housed within the cooking chamber 15.

[0028] FIG. 5 shows a perspective view of the container C' of this embodiment, and FIG. 6 shows an explanatory diagram of the power conversion mechanism 71 and its surrounding essential components. Referring to these figures, the container C' will be described. 61 is the container body, which is formed as a cylindrical, bottomed, approximately circular shape when viewed from above. 62 is the container lid that covers the top opening of the container body 61, which is formed as a roughly circular, plate-like shape similar to the container body 61 when viewed from above. The container body 61 and the container lid 62 of this embodiment are formed from heat-resistant resin. Therefore, even if the food S to be cooked is placed in the container C' and the container C' is placed in the cooking chamber 15 and microwaved, there is no risk of radio wave concentration, allowing for safe microwave heating. The container body 61 and the container lid 62 may also be formed from a non-metallic, heat-resistant material, such as heat-resistant glass or ceramic.

[0029] The container body 61 is primarily comprised of a cylindrical storage section 63 with a bottom for storing the food S to be cooked, and flanges 64 extending outward from the upper end of the storage section 63. The flanges 64 are placed on the shelf supports 22, 22 to suspend the container body 61, i.e., the container C'. Therefore, the length from the outer end of one flange 64 to the outer end of the other flange 64 is formed to be approximately the same as the length from the left side wall 15d to the left side wall 15e of the cooking chamber 15. The storage section 63 may be formed with a handle that can be gripped when placing the container body 61 in or removing it from the cooking chamber 15. Furthermore, the upper end of the storage section 63 or the upper surfaces of the flanges 64 may be formed with a lid positioning portion that positions the container lid 62 on the container body 61 to prevent misalignment when the container lid 62 is placed on the container body 61, or an engagement portion for engaging the container lid 62 may be formed.

[0030] The container lid body 62 is mainly composed of a substantially circular plate-shaped lid body 66, flanges 67, 67 extending outward from the left and right side surfaces of the lid body 66, a blade 68 extending downward from the lid body 66, a rod-shaped transmission part 69 extending rearward along the upper surface of the lid body 66, and a cover 70 provided on the upper surface of the lid body 66.

[0031] The lid body 66 covers the top opening of the storage compartment 63 and is provided with through-holes, such as a steam vent 72 for discharging steam generated from the food S in the storage compartment 63 to the outside of the container C' and a blade hole (not shown) for rotatably supporting the blade 68. When the container C' is suspended, the flanges 67, 67 are pressed down from above by contacting the shelf supports 22, 22 with their upper surfaces, preventing the lid body 66 and the storage compartment 63 from separating even when the internal pressure of the container C' increases. Therefore, the length from the outer end of one flange 67 to the outer end of the other flange 67 is formed to be approximately the same as the length from the left wall 15d to the left wall 15e of the cooking chamber 15. If positioning portions are formed on the upper end of the storage compartment 63 or on the upper surfaces of the flanges 64, 64, positioning receivers corresponding to the positioning portions may be formed on the underside of the lid body 66 or on the undersides of the flanges 67, 67.

[0032] Blade 68 rotates to stir food S contained in container portion 63 of container body 61, and functions as a rotating means. Transmission portion 69 rotates to rotate blade 68. More specifically, with reference to Figure 6, blade 68 has a shaft portion 74 that serves as the axis of rotation when rotating, stirring arms 75, 75 that are provided near the tip of shaft portion 74 and extend downward, and a worm wheel 76 provided at the base end of shaft portion 74.

[0033] The shaft portion 74 passes through the blade hole of the lid main body 66 and rotates using the blade hole as a bearing. In this embodiment, a worm wheel 76 is removably attached to the base end of the shaft portion 74. After the shaft portion 74 is inserted into the blade hole, the worm wheel 76 is attached to the base end of the shaft portion 74, and the worm wheel 76 rotates with the worm wheel 76 abutting against the upper surface of the lid main body 66. The shaft portion 74 may be configured to be separable. For example, a disk-shaped flange may be provided midway along the shaft portion 74, and the shaft portion 74 may be separated below the flange. After the shaft portion 74 is inserted into the blade hole, the shaft portion 74 may be assembled, and the flange of the shaft portion 74 may rotate with the flange abutting against the upper surface of the lid main body 66. In this embodiment, the shaft portion 74 is formed of heat-resistant resin. However, it may also be formed of a non-metallic material, such as ceramic, that is harder and has better sliding properties than heat-resistant resin.

[0034] The agitating arms 75, 75 are positioned within the storage compartment 63 when the lid body 66 is attached, and agitate the food S in the storage compartment 63 when the blade 68 rotates. When the container lid 62 is placed over the container body 61, the agitating arms 75, 75 preferably have their tips extending to near the bottom of the storage compartment 63 and their base ends positioned near the upper end of the storage compartment 63, allowing the food S to be agitated regardless of the amount of food S in the storage compartment 63. In this embodiment, the agitating arms 75, 75 are branched from the tip of the shaft 74. While two agitating arms 75, 75 are shown in FIGS. 5 and 6, the present invention is not limited to this configuration. For example, three or more agitating arms 75 may be provided. In this embodiment, the agitating arms 75, 75 all have substantially the same shape, but the present invention is not limited to this configuration and do not have to have the same shape. Furthermore, if the shaft portion 74 is configured to be separable, the shapes of the stirring arms 75, 75 can be different for each lower part of the shaft portion 74 to create variations. For example, when cooking stews, the stirring arms 75, 75 can be made pointed as shown in Figures 5 and 6, and when cooking liquids such as soup, the stirring arms 75, 75 can be made spatula-shaped, allowing the stirring arms to be used according to the type of food S. This not only prevents uneven heating of the food S, but also widens the range of cooking methods available for microwave heating.

[0035] Worm wheel 76 transmits the rotational force of transmission unit 69 to shaft unit 74 via worm 79, and worm wheel 76 and worm 79 together form a worm gear mechanism serving as power conversion mechanism 71. For this reason, the rotational speed of worm wheel 76 is configured to be slower than the rotational speed of worm 79, and the diameter, pitch, and module of worm wheel 76 are determined taking into consideration parameters such as how much the rotational speed of blade 68 should be reduced from the rotational speed of connection unit 83, i.e., the rotational speed of drive motor 85, and how much force is required on blade 68 to stir food S.

[0036] The transmission unit 69 has a shaft portion 78 that serves as a rotation axis during rotation, a worm 79 provided near the tip of the shaft portion 78, a joint 80 provided at the base end of the shaft portion 78, and a cylindrical tubular portion 81 provided on the outer periphery of the shaft portion 78. Therefore, the transmission unit 69 is configured so that the shaft portion 78, worm 79, and joint 80 are integrated, and these components and the tubular portion 81 are separate.

[0037] The shaft portion 78 rotates using the cylindrical portion 81 as a bearing. In this embodiment, the worm 79 or joint 80 is removably attached to the base end or tip end of the shaft portion 78, and after the shaft portion 78 is inserted into the cylindrical portion 81, the worm 79 or joint 80 is attached to the base end or tip end of the shaft portion 78, thereby rotating inside the cylindrical portion 81. Note that in this embodiment, the shaft portion 78 is made of heat-resistant resin, but it may also be made of a non-metallic material, such as ceramic, that is harder and has better sliding properties than heat-resistant resin.

[0038] The worm 79 is a cylindrical worm configured to mesh with the worm wheel 76 of the blade 68, and when it rotates, it rotates the worm wheel 76, converting the rotational direction of the shaft 78 to the rotational direction of the shaft 74, and as described above, forms part of the worm gear mechanism. Note that the lid main body 66 or the cover 70 may be configured to have a bearing or abutment for the worm 79, which makes it easier to position the worm 79 and allows the worm 79 to rotate stably.

[0039] The joint 80 is connected to a connecting portion 83 (described later) provided on the rear wall 15c of the cooking chamber 15, and transmits power from the drive motor 85 to the shaft 78 via the connecting portion 83. The rear end surface of the joint 80, which is the contact portion with the connecting portion 83, is provided with projections and recesses that match the connecting portion 83 and enable connection through mechanical meshing. The joint 80 and the connecting portion 83 are configured in a mutually engaging female-male shape, which reliably connects to the connecting portion 83 and reliably transmits rotational force from the connecting portion 83 to the shaft 78. The protrusions of the joint 80, that is, the claws, may all be formed in the same shape and arranged rotationally symmetrically about the rotation axis of the joint 80. The joint 80 and the connecting portion 83 may also be formed as a dog clutch. The cylindrical portion 81 functions as a bearing that rotatably supports the shaft 78 and also functions as a cover that covers the outer periphery of the shaft 78.

[0040] The cover 70 covers the power conversion mechanism 71, including the worm wheel 76 and the worm 79, thereby blocking access to the power conversion mechanism 71 and functioning as an outer shell to prevent the entry of dust, dirt, and other contaminants and to prevent contact with people and objects. The cover 70 mainly comprises a hollow cover main body 70a with an open bottom, and a tube fixing portion 70b formed on the rear side of the cover main body 70a to correspond to the outer periphery of the tubular portion 81. The cover main body 70a functions as the outer shell described above, and the power conversion mechanism 71 is disposed within the space surrounded by the cover main body 70a and the top surface of the lid main body 66. The tube fixing portion 70b fixes the tubular portion 81, and the end of the tubular portion 81 on the worm 79 side is fixed to the cover 70, thereby attaching the transmission unit 69 to the container lid 62.

[0041] FIG. 7 is a schematic diagram of the cooking chamber 15. Referring to FIG. 7, reference numeral 83 denotes a connector provided on the rear wall 15c and connectable to the joint 80. By connecting the joint 80 to the connector 83, the connector 83 transmits power from a drive motor 85 (drive means) provided outside the cooking chamber 15 to the transmission unit 69 of the container lid 62 (agitation means). In this embodiment, the connector 83 is substantially cylindrical and rotatably disposed at a height near the shelf support 22 for the container lid 62 so that its central axis is aligned with the rotation axis of the shaft 78 of the transmission unit 69. The front end surface of the connector 83, which is the contact point with the joint 80, is provided with projections and recesses that match the joint 80 and enable connection through mechanical interlocking. It is preferable that the protrusions of the connector 83 are all formed in the same shape and are arranged rotationally symmetrical about the rotation axis of the connector 83, which facilitates connection to the joint 80. However, the present invention is not limited to this, and for example, the connection portion 83 may be provided on the left side wall 15d, the right side wall 15e, or the ceiling wall 15b.

[0042] In this embodiment, two shelf supports 22 are provided on each of the left side walls 15d and 15e of the cooking chamber 15. The distance between the upper and lower shelf supports 22 is approximately the same as the sum of the thickness of the flange 64 of the container body 61 and the thickness of the flange 67 of the container lid 62, and the height of the lower shelf support 22 is such that the bottom surface of the storage section 63 does not come into contact with the bottom wall 15a of the cooking chamber 15 when the container body 61 is placed thereon. With this configuration, container C' can be positioned by placing it on shelf supports 22 and suspending it in cooking chamber 15. Furthermore, on each of left and right walls 15d and 15e, the upper shelf supports 22 hold flange 67 of container lid 62 from above, and the lower shelf supports 22 hold flange 64 of container body 61 from below, thereby sandwiching flanges 64 and 67 of container C'. This prevents displacement of container lid 62 from container body 61 even when pressure inside container C' increases due to, for example, boiling of food S. This prevents, for example, spillage of food S from the container or displacement of container lid 62, which releases steam inside container C' and causes a drop in pressure. Note that the present invention is not limited to this configuration, and for example, three or more shelf supports 22 may be provided on each of left and right walls 15d and 15e. Alternatively, one shelf support 22 may be provided on each of the left and right walls 15d and 15e, and the container C' may be placed on the bottom wall 15a of the cooking chamber 15. In this case, the height of the lower surface of the shelf support 22 is made approximately the same as the height of the upper surface of the flange 67 of the container lid 62 of the placed container C', so that the shelf support 22 can hold the flange 67 of the container lid 62 from above.

[0043] 8 shows the main electrical configuration of the cooking device 1 of this embodiment. In this embodiment, in addition to the cooking device 1 described above, a drive motor rotation detection means 86 is electrically connected to the input port of the control means 51, and a drive motor 85 is electrically connected to the output port of the control means 51.

[0044] The drive motor 85 supplies power to rotate the blade 68 in a predetermined direction and functions as a drive means for the blade 68. In this embodiment, the drive motor 85 is disposed outside the cooking chamber 15 and is configured to transmit power to the blade 68 inside the container C' suspended within the cooking chamber 15 via the connection part 83 and the transmission part 69. The drive motor rotation detection means 86 detects the rotation of the drive motor 85. In this embodiment, the control means 51 is configured to receive a detection signal from the drive motor rotation detection means 86 and determine whether a load is applied to the drive motor 85, i.e., whether a load is applied to the connection part 83, based on the rotation speed of the drive motor 85 derived from the detection signal and the power supplied to the drive motor 85.

[0045] For example, when the control means 51 determines that a load is applied to the connection portion 83, it determines that the joint 80 is connected to the connection portion 83, and controls the drive motor 85 to continue driving. On the other hand, when the control means 51 determines that no load is applied to the connection portion 83, it determines that nothing is connected to the connection portion 83, and controls the drive motor 85 to stop driving. Note that this configuration is one example, and the present invention is not limited to this.

[0046] Next, the operation of microwave heating in the first embodiment will be described in detail. With food S placed in the storage section 63 of the container body 61 of container C', when the container lid 62 is placed on top of the container body 61 so that the flanges 64, 64 of the container body 61 overlap the flanges 67, 67 of the container lid 62, the blade 68 of the container lid 62 extends into the storage section 63, and the lid body 66 of the container lid 62 covers the storage section 63 of the container body 61. In this state, when the container C' is placed on the shelf supports 22 and placed in the cooking chamber 15 so that the container C' is suspended in the cooking chamber 15, the upper shelf support 22 holds the flange 67 of the container lid 62 from above, and the lower shelf support 22 holds the flange 64 of the container body 61 from below, so that the shelf supports 22 clamp the flanges 64 and 67 of the container C'. Therefore, when the container C' is placed in the cooking chamber 15, the container lid body 62 is configured so that the transmission part 69 of the container lid body 62 is rearward relative to the container body 61 and extends toward the rear wall 15c of the cooking chamber 15.

[0047] When container C' is moved rearward along shelf support 22, joint 80 of transmission part 69 of container lid 62 connects with connection part 83 of cooking chamber 15, preventing container C' from moving rearward. Therefore, shelf support 22 functions as a positioning means for positioning container body 61 and container lid 62 in cooking chamber 15.

[0048] Then, with the container C' placed in the cooking chamber 15, the door 3 is closed while holding the handle 5 in the hand, and after selecting and operating the menu for microwave cooking using the operating means 8, a command is given to start heating and cooking the food S. The heating control means 53 receives a detection signal from the food temperature detection means 48 and outputs a drive control signal to the microwave heating means 25, causing the microwave generator 25 to be energized and emit microwaves, and the rotational force generated in the antenna motor 29 is transmitted to the antenna 41 to rotate it, controlling the microwaves generated from the surface of the rotating antenna 28 to be supplied into the cooking chamber 15.

[0049] Furthermore, the heating control means 53 sends a drive control signal to the drive motor 85, receives a detection signal from the drive motor rotation detection means 86, and determines whether or not a load is applied to the connection part 83. If the heating control means 53 determines that no load is applied to the connection part 83, it stops sending the drive control signal and controls the drive motor 85 to stop driving. On the other hand, if the heating control means 53 determines that a load is applied to the connection part 83, it continues sending the drive control signal and controls the drive motor 85 to continue driving.

[0050] When the drive motor 85 is driven, the connection portion 83 rotates, transmitting power to the joint 80 connected to the connection portion 83 and to the shaft 78 and worm 79 formed integrally with the joint 80, causing the joint 80, shaft 78, and worm 79 to rotate. The rotation of the worm 79 about an axis extending substantially horizontally in the container C' is converted into rotation of the worm wheel 76 about an axis extending substantially vertically in the container C', and power from the transmission portion 69 is transmitted to the blade 68, causing the shaft 74 and stirring arms 75, 75 formed integrally with the worm wheel 76 to rotate. The blade 68 thus rotates within the container 63, stirring the food S contained in the container 63. The food S is thus cooked while being stirred.

[0051] As described above, the cooking appliance 1 of this embodiment comprises a cooking chamber 15 and a container lid 62 of the container C' as a stirring means capable of stirring the food S to be cooked. The container lid 62 is connected to a connection part 83 of the cooking chamber 15 and is detachably attached by being held by the shelf support 22. The cooking chamber 15 has a connection part 83 that can transmit power from a drive motor 85 as a driving means provided outside the cooking chamber 15 to the container lid 62. The container lid 62 has a blade 68 as a rotating means that rotates for stirring, and a transmission part 69 that is connected to the connection part 83 and rotates to transmit power to the blade 68. An angle is formed between the first axis, which is the rotation axis of the blade 68 positioned approximately vertically in the container C', and the second axis, which is the rotation axis of the transmission part positioned approximately horizontally in the container C'.

[0052] With this configuration, connecting portion 83 can be provided in places other than bottom wall 15a, such as back wall 15c, left side wall 15d, or right side wall 15e of cooking chamber 15, so container lid 62 can be provided in cooking chamber 15 without providing a guide for container C' in bottom wall 15a to make the rotation axis of blade 68 approximately vertical in container C'. Furthermore, when container C' is not in use, container lid 62 is not present in cooking chamber 15, so nothing is placed on bottom wall 15a and all of the space in bottom wall 15a can be used to place objects.

[0053] Furthermore, the transmission part 69 of this embodiment has a joint 80 that connects to the connection part 83, and the joint 80 and the connection part 83 are configured to have a male-female shape that engages with each other. Therefore, the joint 80 and the connection part 83 can be reliably connected, and the rotational force from the connection part 83 can be reliably transmitted to the shaft part 78 via the joint 80.

[0054] In addition, in this embodiment, the container lid 62 as a stirring means is provided on the container lid 62 that covers the upper opening of the container body 61 as a container that can accommodate the food to be cooked S, and the blade 68 as a rotating means is configured to be a blade 68 that can rotate within the container body 61.By providing the stirring means and rotating means in the container C', when the container C' is not in use, there is no stirring means or rotating means in the cooking chamber 15, so items can be placed in all the space on the bottom wall 15a.

[0055] Furthermore, when the container lid body 62 of this embodiment is placed in the cooking chamber 15 while covering the container body 61, the transmission part 69 of the container lid body 62 is configured to face rearward relative to the container body 61 and to be oriented in a predetermined direction extending toward the rear wall 15c of the cooking chamber 15. Therefore, even if the connection part 83 cannot be seen, the joint 80 and the connection part 83 can be easily connected by simply moving the container C' rearward along the shelf support 22.

[0056] Cooking appliance 1 of the present embodiment is also provided with shelf supports 22 as positioning means for positioning container lid 62 in cooking chamber 15, which are provided on left side wall 15d and right side wall 15e, respectively, as the left and right walls of cooking chamber 15, and shelf supports 22 are configured to hold flange 67 of container lid 62 from above, on left side wall 15d and right side wall 15e of cooking chamber 15. With this configuration, it is possible to prevent container lid 62 from shifting position from container body 61 even if the pressure inside container C' increases.

[0057] In addition, the container lid 62 of this embodiment is made of heat-resistant resin, and the blade 68 has a shape with at least two branches at the tip, so there is no risk of radio wave concentration, and microwave heating can be performed safely.

[0058] 9 shows a modification of the first embodiment. This modification is provided with a container holding means 87, and is configured so that the container C″ can be suspended within the cooking chamber 15.

[0059] FIG. 9 is a schematic diagram of cooking chamber 15 of cooking appliance 1 of this modified example. Cooking appliance 1 will be described with reference to this figure. 87 is a container holding means for holding container C" within cooking chamber 15. In container C" of this modified example, the length from the outer end of flange 64 to the outer end of the other flange 64 and the length from the outer end of flange 67 to the outer end of the other flange 67 are shorter than the length from left wall 15d to left wall 15e of cooking chamber 15. In this modified example, connecting portion 83 of cooking chamber 15 is provided near the center of rear wall 15c, and in FIG. 9, it is provided at approximately the same height as lower shelf support 22. Therefore, by suspending the container C" near the approximate center of the cooking chamber 15 and sliding it toward the rear of the cooking chamber 15, or by holding the container C" by the container holding means 87 and placing the container holding means 87 on the shelf support 22 and sliding it toward the rear of the cooking chamber 15, the joint 80 of the transmission part 69 of the container C" can be connected to the connection part 83.

[0060] The container C" and the container holding means 87 are formed from non-metallic heat-resistant materials such as heat-resistant resin, heat-resistant glass, or ceramic, and even if the food to be cooked S is placed in the container C" and the container C" is attached to the container holding means 87 in the cooking chamber 15 and microwave heating is performed, there is no risk of radio wave concentration, so microwave heating can be performed safely.The container holding means 87 is mainly composed of a holding means main body 88 and holding portions 89, 89.

[0061] The holding means main body 88 is placed on the shelf support 22 to suspend the container C" via the holding portions 89, 89. The holding means main body 88 of this modified example is formed in a plate-like portion and has a depth approximately the same as the front and back of the cooking chamber 15, like the square plate 21 of the first embodiment, but this is just one example and other shapes are also acceptable as long as it can be placed on the shelf support 22 and the container C" can be suspended in the specified position.

[0062] The holding portions 89, 89 hold the flanges 64, 64 of the container body 61 of the container C" from below. The holding portion 89 of this modified example is formed in a substantially L-shaped cross section, and each holding portion 89, 89 is configured to have a vertical wall portion 89-1, 89-1 extending vertically downward from the holding means body 88, and a horizontal wall portion 89-2, 89-2 extending horizontally inward from the lower end of the vertical wall portion 89-1 toward the other holding portion 89. Here, the vertical wall portions 89-1, 89-1 of this modified example are formed in the shape of a plate substantially parallel to the left side wall 15d and the left side wall 15e, and the horizontal wall portions 89-2, 89-2 are formed in the shape of a plate substantially parallel to the bottom wall 15a, but these are just examples.

[0063] In this modified example, the height of the vertical wall portion 89-1 is formed to be approximately the same as the height from the underside of the flanges 64, 64 of the container C" to the upper end of the cover 70 of the container lid body 62, and when the container C" is held in the holding portions 89, 89, the upper end of the cover 70 contacts the underside of the holding means main body 88 to hold the container lid body 62 from above, and the container holding means 87 clamps the container C" from above and below, so that the container lid body 62 will not come off the container main body 61 even if the pressure inside the container C" rises due to boiling of the food being cooked, etc. Furthermore, the distance between the inner tips of the horizontal wall portions 89-2, 89-2 is formed to be approximately the same as the outer diameter of the storage portion 63 of the container body 61 of the container C", and the container C" can be positioned within the cooking chamber 15 simply by inserting the container C" between the horizontal wall portions 89-2, 89-2. The distance between the inner walls of the vertical wall portions 89-1, 89-1 may also be configured to be approximately the same as the length from the outer end of the flange 67 to the outer end of the other flange 67, and since the orientation of the container lid body 62 can be determined simply by inserting the container C" between the holding portions 89, 89, the joint 80 of the transmission portion 69 can be connected to the connection portion 83 of the cooking chamber 15 simply by inserting the container C" between the holding portions 89, 89.

[0064] Even when the cooking device 1 is configured as described above, the joint 80 and the connecting portion 83 can be easily connected simply by moving the container C" rearward along the holding portions 89, 89. Furthermore, by using a container holding means 87 that corresponds to the container C" in the cooking device 1 of this modified example, cooking can be performed with any container C" of any desired shape, rather than being limited to using only containers C" of a specific shape. [Example]

[0065] 10 and 11 show the configuration of a second embodiment of the cooking device 1 of the present invention. In this embodiment, a container C III The transmission part 69' is provided with a container rotation shaft 93 as a rotating part that rotates the container, and is configured so that an angle is formed between the rotation axis of the transmission part 69', which is positioned approximately horizontally in the cooking chamber 15, and the rotation axis of the container rotation shaft 93.

[0066] Fig. 10 shows a schematic cross-sectional view of the cooking device 1 of this embodiment, and Fig. 11 shows an explanatory diagram of the power conversion mechanism 71' and its surrounding essential parts of this embodiment. Referring to these figures, the cooking device 1 will be described. 91 is a container C III The container installation stand is configured mainly with an installation stand main body 92 formed in the shape of a horizontal triangular prism with a cross section of a right triangle, a transmission part 69' extending rearward from a back surface 92b of the installation stand main body 92, and a container rotation shaft 93 extending through a slope 92c of the installation stand main body 92. III The container installation table 91 has a shaft holding portion 95 for inserting and holding the container rotation shaft 93. III The container setting table 91 and the container C in this embodiment function as a stirring means for stirring the food S to be cooked. III is made of a non-metallic heat-resistant material such as heat-resistant resin, heat-resistant glass, or ceramic, and the container installation table 91 and the container C III Even if the food is housed in the cooking chamber 15 and heated in a microwave oven, there is no risk of microwave concentration, so microwave heating can be carried out safely.

[0067] The installation table main body 92 surrounds the mechanism where the transmission unit 69' and the container rotation shaft 93 engage, and functions as a housing. The installation table main body 92 primarily comprises a bottom surface 92a, which is the surface that contacts the bottom wall 15a when the container installation table 91 is placed in the cooking chamber 15; a back surface 92b, which is the surface facing the rear wall 15c; and a sloped surface 92c, which is the surface connecting the front edge of the bottom surface 92a and the upper edge of the rear wall 15c. The surface of the sloped surface 92c preferably has good sliding properties, and the sloped surface 92c may be formed of a material with good sliding properties or may be processed to improve the sliding properties of the sloped surface 92c. A through-hole 94 through which the transmission unit 69' passes is drilled in the back surface 92b, and a through-hole 96 through which the container rotation shaft 93 passes is drilled in the sloped surface 92c. In this embodiment, the through hole 94 is formed to function as a bearing for the transmission part 69', and the through hole 96 is formed to function as a bearing for the container rotation shaft 93, but this is just one example, and the configuration may also include bearings provided in addition to the through hole 94 and the through hole 96.

[0068] The container rotation axis 93 is III By rotating the container C, III The transmission unit 69' rotates the container rotation shaft 93 by rotating. In more detail with reference to FIG. 10, the container rotation shaft 93 rotates the container C. III a container mounting portion 93a for mounting the container C; III and a bevel gear 93b provided at the end opposite to the end to which the gear is attached.

[0069] The container attachment portion 93a of this embodiment is axial, and the container C III The end of the attachment side of the container C is formed so that it tapers toward the tip, for example, in a conical shape. IIIThe shape of the container mounting portion 93a corresponds to the shape of the shaft holding portion 95, and for example, the diameter of the shaft is approximately the same as the diameter of the shaft holding portion 95, and the length of the container mounting portion 93a is configured to be approximately the same as or shorter than the sum of the depth of the shaft holding portion 95 and the thickness of the inclined surface 92c of the installation base main body 92. The surface of the container rotation shaft 93 may be processed to be rough, which can increase the frictional force with the shaft holding portion 95 and make it easier to insert the container C. III The rotational force of the container rotation shaft 93 is transmitted to the container C via the shaft holding portion 95. III This makes it easier for people to understand.

[0070] Bevel gear 93b transmits the rotational force of transmission unit 69' to container mounting unit 93a via bevel gear 97 of transmission unit 69', and bevel gear 93b and bevel gear 97 form a bevel gear mechanism serving as power conversion mechanism 71'. The bevel gear portion of bevel gear 93b and the bevel gear portion of bevel gear 97 have a reference cone angle corresponding to the angle between the rotation axis of container mounting unit 93a and the rotation axis of transmission unit 69', and in this embodiment, the reference cone angle corresponds to the angle between container mounting unit 93a and shaft portion 78' of transmission unit 69'. In this embodiment, the bevel gear 93b is larger than the bevel gear 97, and the number of teeth of the bevel gear 93b is greater than the number of teeth of the bevel gear 97. Therefore, the rotation speed of the bevel gear 93b is slower than the rotation speed of the bevel gear 97. However, the present invention is not limited to this. For example, it is possible to determine how much the rotation speed of the container mounting part 93a is reduced from the rotation speed of the connecting part 83, i.e., the rotation speed of the drive motor 85, and the rotation speed of the container C. III The shapes, diameters, tooth pitches, etc. of bevel gears 93b and 97 are determined taking into consideration parameters such as how much force is required on container mounting portion 93a to rotate the container. In this embodiment, both bevel gear 93b of container rotation shaft 93 and bevel gear 97 of transmission portion 69' are bevel gears, but the present invention is not limited to this, and at least one of bevel gear 93b and bevel gear 97 may be a bevel gear. In this case, the bevel gear portion of the bevel gear is configured to have a reference cone angle corresponding to the angle between the rotation axis of container mounting portion 93a and the rotation axis of transmission portion 69'.

[0071] The transmission unit 69' of the present embodiment has a shaft portion 78' formed by integrating the shaft portion 78 and the cylindrical portion 81 of the first embodiment, and a bevel gear 97 is provided at the end of the shaft portion 78' opposite the joint 80. The shaft portion 78', the joint 80, and the bevel gear 97 are integrally formed. Note that, as in the first embodiment, the shaft portion 78' and the cylindrical portion 81 may be formed as separate bodies, and the joint 80 and the bevel gear 97 may be provided at both ends of the shaft portion 78'. Note that a short length of the shaft portion 78' is preferable, as this can prevent the position of the joint 80 from moving downward due to the influence of gravity, etc., and makes it easier to connect the joint 80 to the connection portion 83 by moving the container installation stand 91 near the connection portion 83.

[0072] In this embodiment, the hot air motor 37 of the hot air unit 34 is used as the driving means provided outside the cooking chamber 15. Therefore, the motor for heating the oven and the container C III The hot air motor 37 also serves as the motor that supplies power to the container installation stand 91 that rotates the container 36, thereby reducing the number of motors mounted in the cooking appliance 1 and reducing costs while increasing the space for mounting components within the cooking appliance 1. Note that a path changing means may be provided that enables the drive transmission path of the hot air motor 37 to be changed, so that when power is transmitted to the hot air fan 36, power is not transmitted to the connection part 83, and conversely, when power is transmitted to the connection part 83, power is not transmitted to the hot air fan 36.

[0073] Next, the operation of microwave heating in the second embodiment will be described in detail. With the transmission unit 69' positioned at the rear, the container installation stand 91 is placed on the bottom wall 15a of the cooking chamber 15, and the container installation stand 91 is moved so that the joint 80 of the transmission unit 69' is connected to the connection unit 83 of the cooking chamber 15. After the joint 80 and the connection unit 83 are connected, the container C is III With the food to be cooked S placed in the container C, III The container C is inserted into the shaft holding portion 95 by inserting the container mounting portion 93a up to the inclined surface 92c. IIIWhen the container C is attached to the container rotation shaft 93, III The container is held on a container rotation axis 93 at an angle of the inclined surface 92c relative to the bottom wall 15a.

[0074] and container C III With the microwave oven placed in the cooking chamber 15, the user closes the door 3 while holding the handle 5 with the hand, selects a menu for microwave cooking using the operating means 8, and then issues a command to start cooking the food S by heating. As described above in the first embodiment, the microwave generator 25 is energized to supply and radiate microwaves, the antenna 41 is rotated, and the microwaves generated from the surface of the rotating antenna 28 are supplied into the cooking chamber 15.

[0075] The heating control means 53 also sends a drive control signal to the hot air motor 37, and receives a detection signal from the hot air motor rotation detection means 38 to determine whether or not a load is applied to the connection part 83. If the heating control means 53 determines that no load is applied to the connection part 83, it stops sending the drive control signal and controls the hot air motor 37 to stop driving. On the other hand, if the heating control means 53 determines that a load is applied to the connection part 83, it continues sending the drive control signal and controls the hot air motor 37 to continue driving.

[0076] When the hot air motor 37 is driven, the connection part 83 rotates, and power is transmitted to the joint 80 connected to the connection part 83, and to the shaft part 78' and bevel gear 97 formed integrally with the joint 80, causing the joint 80, the shaft part 78', and the bevel gear 97 to rotate. Then, the rotation of the bevel gear 97 about an axis extending in a substantially horizontal direction on the bottom wall 15a is converted into the rotation of the bevel gear 93b about an axis having substantially the same angle as the angle of the inclined surface 92c relative to the bottom wall 15a, and the power from the transmission part 69' is transmitted to the container rotation shaft 93, causing the container attachment part 93a formed integrally with the bevel gear 93b to rotate, and the container C attached to the container attachment part 93a to rotate. III The container C rotates together with the container mounting portion 93a. III When the container C rotates at the angle of the inclined surface 92c relative to the bottom wall 15a, IIIThe food S contained in the container C III The food S is stirred by two directions of movement, that is, the direction of rotation of the food S and the direction of fall of the food S due to its own weight. In this way, the food S is cooked while being stirred.

[0077] As described above, the heating cooker 1 of this embodiment comprises a cooking chamber 15 and a container mounting stand 91 as a stirring means capable of stirring the food to be cooked S, the container mounting stand 91 is detachably attached to the cooking chamber 15, the cooking chamber 15 has a connection part 83 that can transmit power from a hot air motor 37 as a driving means provided outside the cooking chamber 15 to the container mounting stand 91, the container mounting stand 91 has a container rotation shaft 93 as a rotating means that rotates for stirring, and a transmission part 69' that is connected to the connection part 83 and rotates to transmit power to the container rotation shaft 93, and is configured so that an angle can be formed between the first axis which is the rotation axis of the container rotation shaft 93 and the second axis which is the rotation axis of the transmission part 69'.

[0078] With this configuration, connecting portion 83 can be provided in places other than bottom wall 15a, such as back wall 15c, left side wall 15d, or right side wall 15e of cooking chamber 15, and container mounting stand 91 can be provided in cooking chamber 15 without providing a guide for container mounting stand 91 in bottom wall 15a. Furthermore, when container mounting stand 91 is not in use, there is no container mounting stand 91 inside cooking chamber 15, so nothing is placed on bottom wall 15a and items can be placed in all the space on bottom wall 15a.

[0079] Furthermore, the transmission section 69' in this embodiment has a joint 80 that connects to the connection section 83, and the joint 80 and the connection section 83 are configured to have a male-female shape that engages with each other. This allows the joint 80 and the connection section 83 to be reliably connected, and the rotational force from the connection section 83 can be reliably transmitted to the shaft section 78' via the joint 80.

[0080] The container setting table 91 of this embodiment is a container C that can accommodate food S. III The container rotation axis 93 can rotate the container C IIIThe container C from the cooking chamber 15 can be attached and detached. III It makes it easy to take in and out the container C. III The food S contained in the container C is III The food S can be cooked while being stirred by adding two directions of movement, that is, the direction of rotation and the direction of fall of the food S due to its own weight.

[0081] In addition, in this embodiment, the container rotation shaft 93 and the transmission unit 69' each have a bevel gear 97 and a bevel gear 93b as gears, and the bevel gear 97 and the bevel gear 93b are engaged with each other, and by engaging the bevel gear 97 and the bevel gear 93b, power from the hot air motor 37 can be transmitted to the container rotation shaft 93 via the transmission unit 69'.

[0082] In addition, at least one of the bevel gears 97 and 93b in this embodiment is configured as a bevel gear, and an angle can be created between the rotation axis of the container rotation shaft 93 and the rotation axis of the transmission unit 69', so that the power from the hot air motor 37 can be transmitted at an angle relative to the axis of the hot air motor 37.

[0083] In addition, the hot air motor 37 in this embodiment is configured as a motor of the hot air unit 34, which is a heating means that can heat the food to be cooked S by oven heating, and this reduces the number of motors installed in the cooking appliance 1, thereby reducing costs and increasing the space for installing parts within the cooking appliance 1.

[0084] 12 shows the configuration of a modified example of the second embodiment. A container setting table 91' of this modified example is provided with a rotating plate 101 on which a container C is attached and rotated.

[0085] 12, the cooking device 1 of this modified example will be described. Reference numeral 101 denotes a rotating plate provided at the end of the container mounting portion 93a of the container rotation shaft 93' opposite the bevel gear 93b, and is mainly composed of a plate-shaped rotating plate main body 102 and a ribbed container holding portion 103. Therefore, the rotating plate 101 of this modified example functions as a rotating means together with the container rotation shaft 93. Like the other components of the container setting stand 91' described above, the rotating plate 101 of this modified example is made of a non-metallic heat-resistant material such as heat-resistant resin, heat-resistant glass, or ceramic.

[0086] The rotating plate main body 102 is used to place a container C, and the container C can be rotated by rotating the rotating plate main body 102 with the container C placed thereon. While the rotating plate main body 102 in this modified example is preferably formed in a disk shape, the present invention is not limited to this, and any shape can be used as long as it can place and rotate a container C. The surface of the rotating plate main body 102 on which the container C is placed may be roughened to function as an anti-slip surface and prevent the container C from slipping. An engaging member or a connecting member that can engage with the container C may be provided on the surface of the rotating plate main body 102 on which the container C is placed, and the container C can be fixed to the surface of the rotating plate main body 102 on which the container C is placed even without the container holding portion 103. The rotating plate main body 102 may also be configured to be detachable from the container rotation shaft 93'. In this case, a shaft holding portion 95 for the container CIII may be formed in the center of the surface on which the container rotation shaft 93' of the rotating plate main body 102 is attached.

[0087] The container holding portion 103 holds the container C. In this modified example, the container holding portion 103 is formed in a rib shape extending upward from the container C placement surface of the rotating plate main body 102, and is formed so that the inner circumference has approximately the same shape as the outer circumference of the bottom of the container C when viewed from above. Note that this is just one example, and multiple container holding portions 103, such as three or four, may be configured to be provided at equal intervals along the outer circumference of the bottom of the container C, and each of these container holding portions 103 may be configured to be movable in the radial direction of the rotating plate main body 102 so that the distance of the container holding portion 103 from the center of the rotating plate main body 102 can be changed depending on the container C. Furthermore, the inner surface of the container holding portion 103, which comes into contact with the container C, may be processed to be rough, which functions as an anti-slip surface and prevents the container C from shifting.

[0088] With this configuration, even if the container C is not dedicated to the cooking device 1, by attaching the container C to the rotating plate 101, it is possible to obtain the same effects as those described above in the second embodiment.

[0089] The present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the spirit of the present invention. For example, the first and second embodiments and their modifications may be combined. Furthermore, the configurations and shapes of the components of the present embodiment and its modifications are not limited to those shown in the drawings, and may be modified as appropriate.
