Description

[Technical Field]

[0001] The present disclosure relates to a cooking device for cooking ingredients. [Background technology]

[0002] Conventionally, in the field of cooking appliances, there are known appliances that not only simply detect the temperature of the bottom surface of the container and heat it by providing a temperature sensor and heating means below the container that is the object to be heated, but also have various additional cooking functions.Patent Document 1 discloses such a cooking appliance that has a pressure sensor that detects the pressure inside the container and a pressurizing device that pressurizes the inside of the container based on the detection result of the pressure sensor, and performs pressurized cooking.

[0003] Furthermore, apart from the cooking appliances having additional cooking functions as shown in Patent Document 1, so-called tabletop cooking appliances that are used on a table or the like are also known. While such tabletop cooking appliances only have the function of heating the bottom surface of a container placed on the top plate, they have the advantage of being easy to handle.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-137114 Summary of the Invention [Problem to be solved by the invention]

[0005] However, even in a tabletop cooking device, when an additional cooking function such as that shown in Patent Document 1 is provided, the cooking device becomes larger and more complex in structure due to the devices for providing the additional cooking function (for example, a pressure sensor and a pressurizing device) and the mechanism for attaching the devices to the cooking device, which results in a loss of the ease of handling that tabletop cooking devices have.

[0006] The present disclosure has been made in light of the above-mentioned problems, and aims to provide a cooking device that is easy to handle and has a wide range of cooking functions. [Means for solving the problem]

[0007] The heating cooker according to the present disclosure comprises a main body, a heating unit provided inside the main body for heating a container placed on the top surface of the main body, and an additional function unit which is a device for performing processing related to the contents of the container and is provided so as to be detachable from the main body. [Effects of the Invention]

[0008] According to the cooking device of the present disclosure, the additional function unit for performing processes related to the contents of the container is detachable from the main body. Therefore, the additional function unit can be used when necessary depending on the cooking content, so the cooking device can achieve both easy handling and a wide range of cooking functions.

[0010] A preferred embodiment of the cooking device 1 of the present disclosure will be described below with reference to the drawings. Note that the present disclosure is not limited to the embodiments described below. The size and shape of each component in the drawings are shown for ease of explanation and may differ from the actual size and shape. Note that in the following drawings, the surface of the cooking device 1 on which the object to be heated is placed is the upper surface, the left-right direction is indicated by the X-axis, the depth direction is indicated by the Y-axis, and the up-down direction is indicated by the Z-axis.

[0011] Embodiment 1 1 and 2 are schematic diagrams of a cooking device 1 according to the first embodiment, viewed obliquely. FIG. 3 is a schematic diagram showing a cross section of the cooking device 1 according to the first embodiment. FIG. 3 shows a cross section of the cooking device 1 of FIG. 1, cut along the YZ plane of FIG. 1. FIGS. 1 and 3 show the cooking device 1 during cooking with a container P, which serves as an object to be heated, placed thereon, and FIG. 2 shows the cooking device 1 during non-cooking. The container P is a pot into which ingredients such as meat, fish, vegetables, and seasoning liquid (water and seasonings) are placed. The cooking device 1 of the first embodiment is a so-called tabletop cooking heater. As shown in FIGS. 1 to 3, the cooking device 1 has a cooking unit 2, a common mechanism unit 5, and an in-container temperature sensor 6. While FIG. 1 shows only the in-container temperature sensor 6 as an example of an additional function unit of the present disclosure, other additional function units may be included. Other examples of additional function units will be described later.

[0012] The cooking unit 2 has a main body 21 made up of a box body 22 and a top plate 23. The main body 21 has a generally rectangular parallelepiped shape overall. The box body 22 has a box-like shape with an open top. The top plate 23 is a plate on which a container made of a non-metallic material is placed. The top plate 23 is a member that forms the top surface of the main body 21 and covers the opening on the top surface of the box body 22.

[0013] A heating area 24 is formed in approximately the center of the top plate 23. A heating unit 3 is housed below the heating area 24 within the main body 21. The heating unit 3 will be described later. The heating area 24 is an area where an object to be heated is placed. At least the portion of the top plate 23 where the heating area 24 is located is made of heat-resistant glass.

[0014] Cooking appliance 1 has an operation display device 25. Operation display device 25 is, for example, a touch panel, and is provided on top panel 23. Operation display device 25 accepts inputs from the user, such as turning the power of cooking appliance 1 on / off, setting the heat power, setting the menu, and starting and stopping cooking. Operation display device 25 also displays the currently set heat power, cooking menu, and device information of the additional function units. The device information of the additional function units will be described later. Note that operation display device 25 may be provided with a display unit, for example, consisting of a display or LED, and an operation unit, for example, consisting of a dial or tactile switch, separately.

[0015] The cooking unit 2 has a heating unit 3, a bottom temperature sensor 4, a common mechanism unit 5, an internal container temperature sensor 6, and a control unit 7. The heating unit 3 is housed inside the main body 21 and is a coil formed by winding metal. When a high-frequency current is supplied to the heating unit 3 from an inverter (not shown), it generates a magnetic field and heats the bottom of the container P by electromagnetic induction. The heat power of the heating unit 3 is controlled by the control unit 7. The heating unit 3 may also be an electric heater.

[0016] The bottom temperature sensor 4 is a sensor that detects the temperature of the bottom of the container P. The heating unit 3 is wound around the heating unit 3, avoiding the position where the bottom temperature sensor 4 is located. The bottom temperature sensor 4 is an infrared sensor that detects the temperature of the container P by passing through the glass top plate 23. The bottom temperature sensor 4 may also be a contact-type thermistor. The bottom temperature sensor 4 transmits the detection result to the control device 7.

[0017] The common mechanism 5 is used to connect multiple additional function units to the cooking appliance 1. Three connection ports 51 are formed on the top surface of the common mechanism 5, to which additional function units such as the internal container temperature sensor 6 can be attached. The number of connection ports 51 is not particularly limited. In the cooking appliance 1, the additional function units connected to the respective connection ports 51 of the common mechanism 5 can be used simultaneously. The common mechanism 5 is provided in the center of the main body 21 in the left-right direction, and has a shape that is generally elongated upward. This allows the additional function unit to be easily attached by simply connecting the additional function unit from above to the common mechanism 5, which is already arranged as a base, with the container P placed in the heating region 24.

[0018] The common mechanism 5 is attached to the main body 21 by fitting the convex installation portion 26 of the main body 21 into the concave opening 52 provided at the bottom. At this time, the main body 21 and the common mechanism 5 are electrically connected. The common mechanism 5 can be freely attached and detached from the main body 21 by the user. Therefore, when the additional function units are not in use, the unit consisting of the common mechanism 5 and the additional function units can be removed and used as the cooking device 1 that simply controls heating based on the detection results of the bottom temperature sensor 4. Furthermore, since the unit consisting of the common mechanism 5 and the additional function units can be removed and stored, the cooking device 1 is easy to store even when not in use. Furthermore, the installation portion 26 is located behind the heating region 24. Therefore, the common mechanism 5 and the additional function units are positioned further back than the container P. Therefore, when the user pours or mixes contents in the container P, the common mechanism 5 and the additional function units do not get in the way, preventing seasoning liquid or the like from spilling and contaminating the connection between the common mechanism 5 and the main body 21.

[0019] The in-container temperature sensor 6 detects the temperature of the liquid seasoning or the like in the container P. The in-container temperature sensor 6 has a connection part 61, an input part 62, and a sensor body 63. The connection part 61 forms the upper part of the in-container temperature sensor 6 and is attached to the connection port 51 of the common mechanism part 5. The input part 62 extends downward from the connection part 61 and is inserted into the container P. The sensor body 63 is a thermistor, a thermocouple sensor, or the like. The sensor body 63 is provided below the input part 62 of the in-container temperature sensor 6 (for example, within 30 mm from the tip). The lower end of the input part 62 of the in-container temperature sensor 6 is positioned near the bottom of the container P so that at least the sensor body 63 is immersed in the liquid seasoning in the container P. The in-container temperature sensor 6 inputs the detection result to the control device 7 via the common mechanism part 5. Furthermore, the in-container temperature sensor 6 can detect the temperature distribution in the vertical direction by incorporating the sensor bodies 63 at multiple different positions in the vertical direction.

[0020] Although it is possible to estimate the temperature inside the container P using the bottom temperature sensor 4 and use it for cooking control, the bottom temperature sensor 4 only acquires the temperature of the bottom of the container P through the top surface. Therefore, when using the bottom temperature sensor 4 to estimate the temperature inside the container P, there may be a discrepancy between the detected temperature and the actual temperature. Also, there may be a delay in outputting the estimated temperature. Therefore, when using only the bottom temperature sensor 4, it was difficult to precisely control the temperature inside the container P. However, by providing an inside-container temperature sensor 6 and directly detecting the temperature of the contents, such as water, inside the container P, it is possible to control heating from the perspective of the temperature of the contents inside the container P. This allows for accurate detection of the conditions inside the container P and allows for cooking control without time delay, making it easier to achieve the desired finished product.

[0021] Any device other than the in-container temperature sensor 6 may be used as the additional function unit in the cooking appliance 1 as long as it performs processing related to the contents of the container P. Next, the specific functions of the additional function unit that can be employed in the first embodiment will be described. The common mechanism unit 5 may be provided with one additional function unit or multiple additional function units. The additional function unit described in the first embodiment is a device that has a different function from the heating unit 3 and the bottom temperature sensor 4.

[0022] For example, the additional function unit may be provided with a sensor that detects a physical quantity of the contents of the container P other than temperature. Specifically, the cooking device 1 has a salt concentration sensor as an additional function unit. The salt concentration sensor and the in-container temperature sensor 6 differ only in the function of the sensor main body 63, and the overall structure of the sensor is similar. The salt concentration sensor detects the salt concentration of the liquid in the container P and transmits the detection result to the control device 7 via the common mechanism unit 5. The cooking device 1 may also have a sensor that detects the sugar content or viscosity of the liquid in the container P as an additional function unit. Furthermore, the cooking device 1 may have a sensor for detecting other specific ingredients, as long as the ingredient can be detected using electrodes. In either case, the overall structure of the sensor and the transmission of the detection result to the control device 7 are common.

[0023] These sensors detect the salt concentration, sugar content, viscosity, etc. in real time, allowing the control device 7 to control heating in response to changes in the detection results. Also, by displaying the detection results on the operation display device 25, the user can adjust the degree of simmering, and can instruct the addition of seasonings and water to achieve the desired finish.

[0024] Furthermore, for example, the additional function unit may be a drive unit that operates based on a control signal sent from the control device 7 and changes the state of the contents of the container P. Specifically, the cooking appliance 1 has, as the additional function unit, a stirrer that stirs the contents of the container P. Although not shown in the figure, the stirrer includes a stirring blade with multiple blades that stirs the contents of the container P, and a drive unit (motor) that rotates the stirring blade. The operation of the drive unit is controlled by a control signal that indicates the number of rotations and the like received from the control device 7. By providing the stirrer, the contents of the container P can be stirred and the contents can be heated evenly.

[0025] The cooking appliance 1 also includes a pressure adjusting device that adjusts the internal pressure of the container P as an additional function unit that functions as a drive device. When using a pressure adjusting device, a sealing unit is required to cover the opening of the container P and seal the container P. The pressure adjusting device is, for example, a pressurizing device. Although not shown, the pressurizing device has an on-off valve that blocks or allows the flow of air through an air vent formed in the sealing unit. When the on-off valve is closed during heating of the container P, the flow of air between the inside and outside of the container P through the air vent is blocked, and the inside of the container P is pressurized. The operation of the on-off valve is controlled by a control signal received from the control device 7 that indicates the open / close state. The pressure adjusting device may also be a decompression device. Although not shown, the decompression device has a pump that exhausts air from the container P through an air vent formed in the sealing unit. The pressure inside the container P is reduced by the exhaust of air from the pump. The operation of the pump is controlled by a control signal received from the control device 7 that indicates the rotation speed. The provision of the pressure adjusting device enables pressurized cooking or reduced-pressure cooking.

[0026] The connection between the additional function unit and the common mechanism unit 5 will be described in detail using FIG. 4. FIG. 4 is a schematic diagram showing a cross section of the cooking device 1 according to the first embodiment. FIG. 4 shows a cross section of the cooking device 1 of FIG. 1 cut along the XZ plane in FIG. 1 from the rear. As shown in FIG. 4, the common mechanism unit 5 has a connection port 51, an appliance control unit 53, and wiring 54 connecting the connection port 51 and the appliance control unit 53. A terminal 61a formed on a connection unit 61 of the additional function unit is inserted into the recessed connection port 51. This electrically connects the additional function unit and the common mechanism unit 5. The additional function unit can be freely attached and detached by the user by inserting or removing the terminal 61a into or from the connection port 51. The additional function unit is used inside the container P and therefore becomes soiled by the contents. Because the additional function unit is configured to be detachable from the common mechanism unit 5, the additional function unit can be removed and washed with water to keep it clean. The multiple connection ports 51 all have the same shape. Furthermore, the terminals 61a of the additional function units also have the same shape regardless of the type of additional function unit. Therefore, an additional function unit can be inserted into any of the multiple connection ports 51. The shape of the terminals 61a of the additional function units may be changed for each type of additional function unit, and some of the multiple connection ports 51 may be adapted to the shape of the terminals 61a of a specific type of additional function unit, thereby providing a dedicated connection port 51 for that specific type of additional function unit. Furthermore, although FIGS. 3 and 4 illustrate concave connection ports 51 and terminals 61a with corresponding shapes, the connection port 51 may also have a flat shape. When a flat connection port 51 is provided, it is preferable to incorporate magnets into the connection port 51 and the terminals 61a to secure them together.

[0027] The appliance control unit 53 supplies drive power to the additional function units via wiring 54. The drive power is supplied from a commercial power source via the cooking unit 2. The appliance control unit 53 identifies the type of additional function unit connected to the common mechanism unit 5. Specifically, the appliance control unit 53 is electrically connected to the control device 7. When the appliance control unit 53 receives a determination request signal from the control device 7, it responds with a determination response signal. The determination request signal is a signal transmitted when the power to the cooking appliance 1 is turned on in order for the control device 7 to determine the type of the additional function unit. Alternatively, the determination request signal may be transmitted when the user performs an appliance recognition operation via the operation / display device 25. The appliance recognition operation is an operation for causing the cooking appliance 1 to recognize the connected additional function unit. The determination response signal is a signal containing information indicating the determination result of the arrangement and type of the additional function unit. The presence or absence of an additional function unit connected to each connection port 51 and the type of the additional function unit can be determined, for example, by supplying additional detection power to each connection port 51 from the common mechanism unit 5 and judging the magnitude of the load at that time.

[0028] Furthermore, when a sensor is provided as an additional function unit, the device control unit 53 relays the detection results received from the additional function unit and transmits them to the control device 7. Furthermore, when a drive device is provided as an additional function unit, the device control unit 53 relays the control signal received from the control device 7 and transmits it to the additional function unit. In this way, the additional function units are able to realize their functions by connecting to the common mechanism unit 5. The device control unit 53 of the common mechanism unit 5 operates in accordance with the multiple additional function units connected to it.

[0029] The control device 7 controls the overall operation of the cooking appliance 1. FIGS. 5 and 6 are hardware configuration diagrams of the control unit 71 of the cooking appliance 1 according to the first embodiment. As shown in FIG. 5, the control device 7 is configured with a processing circuit 101 made up of an ASIC (Application Specific Integrated Circuit) or an FPGA (Field-Programmable Gate Array). As shown in FIG. 6, the control device 7 may also be configured with a processor 102 such as a CPU, and a memory 103 such as a ROM (Read Only Memory). FIG. 6 shows that the processor 102 and the memory 103 are communicatively connected to each other via a bus 104. The processor 102 reads and executes a program stored in the memory 103, thereby realizing the functions of the control device 7. The device control unit 53 of the common mechanism unit 5 also has the same hardware configuration as the control device 7.

[0030] FIG. 7 is a functional block diagram of the cooking device 1 according to the first embodiment. As shown in FIG. 7, the control device 7 includes a control unit 71 and a communication unit 72. The control unit 71 controls the heating unit 3 based on input from the operation display device 25 and the detection result of the bottom temperature sensor 4. Based on the detection result of the bottom temperature sensor 4, the control unit 71 controls the supply of electricity to the heating unit 3 to maintain the temperature of the container P within a certain range. The control unit 71 also detects the occurrence of an empty-heating condition, in which the temperature rises and the moisture in the container P disappears, based on the output result. When the occurrence of an empty-heating condition is detected, the control unit 71 reduces the heat to prevent burning. The control unit 71 can perform the above operations regardless of whether the additional function unit is connected. In other words, the cooking device 1 can perform cooking even when the additional function unit is detached.

[0031] Furthermore, the control unit 71 supplies power and transmits and receives various signals to and from the additional function unit according to the connected additional function unit identified based on the identification response signal, and applies these to cooking control. Specifically, if a sensor such as an internal container temperature sensor 6 is provided as an additional function unit, the control unit 71 reflects the detection results received from the additional function unit in the control of the heating unit 3. Based on the detection results of the internal container temperature sensor 6, the control unit 71 controls the supply of electricity to the heating unit 3 so as to maintain the temperature of the contents of the container P within a certain temperature range. Furthermore, when the detection result of the sensor reaches a predetermined threshold, the control unit 71 may control the heating unit 3 and the drive device to proceed with the cooking process.

[0032] Furthermore, when a drive device is provided as an additional function unit, the control unit 71 drives the drive device based on the cooking sequence of the selected menu or input from the operation display unit 25. The cooking sequence defines the operation of the heating unit 3 and the drive device when the control conditions are met for each cooking step of each menu.

[0033] The control unit 71 displays device information of the additional function units connected to the common mechanism unit 5 on the operation and display unit 25. The device information includes the types of additional function units that are connected to the connection port 51 and are available for use. The control unit 71 changes the display content on the operation and display unit 25 to match the device information of the function units. For example, the control unit 71 displays the type of connected additional function unit using an icon or text, and displays menus that can be cooked using the connected additional function units. However, the control unit 71 may display the additional function units required for each cooking menu, rather than limiting the cooking menus displayed by the additional function units.

[0034] Furthermore, if the additional function unit is a sensor, the device information includes the detection result of the additional function unit. For example, by displaying the salt concentration detected by a salt concentration sensor as the detection result on the operation display device 25, the user can adjust the amount of salt to their preferred level according to the salt concentration. Furthermore, if the additional function unit is a driving device such as a stirring device or a pressure adjusting device, the device information includes the current driving state (either ON or OFF).

[0035] Furthermore, if the control unit 71 determines based on the determination response signal that the multiple connected additional function units cannot be shared, it causes the operation and display device 25 to display an alert. For example, if the drive power that the cooking appliance 1 can supply is limited, additional function units that require relatively large drive power, such as the agitator and pressure reducer, may not be able to be activated simultaneously. Furthermore, if a pressure adjustment device is used as an additional function unit, a sealing unit that seals the container P is required, as described above. For this reason, if a pressure adjustment device is used, the control unit 71 may confirm that all connected additional function units have been placed inside the container P before cooking begins, and then cause the operation and display device 25 to display a message instructing the user to seal the container P.

[0036] The communication unit 72 functions as a communication interface in the control device 7. The communication unit 72 communicates a discrimination request signal and a discrimination response signal with the device control unit 53 of the common mechanism unit 5. The communication unit 72 also communicates with the additional function unit via the device control unit 53 of the common mechanism unit 5. Specifically, when a sensor is provided as the additional function unit, the communication unit 72 transmits the detection result received from the additional function unit to the control unit 71. When a drive device is provided as the additional function unit, the communication unit 72 transmits the control signal received from the control unit 71 to the additional function unit.

[0037] An example of the operation of the cooker 1 will now be described by tracing the cooking process. First, the user places the container P containing ingredients in the heating area 24, and then attaches the common mechanism 5 and additional function units to the main body 21. When the user turns on the cooker 1, available menus are displayed on the operation and display device 25 according to the type of additional function units connected to the cooker 1. When the user selects a menu to be cooked and inputs a command to start cooking, the control unit 71 begins controlling the supply of electricity to the heating unit 3 based on the cooking sequence determined by the menu input from the operation and display device 25. At this time, the progress of the cooking process is controlled based on the detection results of the bottom temperature sensor 4 as well as the various sensors connected as additional function units. Furthermore, if the cooking process includes a stirring process for the contents or a depressurizing or pressurizing process for the container P, the operation of the corresponding stirring device or pressure adjusting device is controlled. When all cooking processes have been performed, the control unit 71 completes the cooking and displays a message to that effect on the operation and display device 25.

[0038] As described above, according to the cooking device 1 of the present disclosure, the additional function unit for performing processes related to the contents of the container P is detachable from the main body 21. Therefore, the additional function unit can be used when necessary depending on the cooking contents, and the cooking device 1 can achieve both ease of handling and a full range of cooking functions.

[0039] The above is a description of the embodiments of the present disclosure. However, the present disclosure is not limited to the configurations of the above embodiments and various modifications and combinations are possible within the scope of the technical concept. For example, in the first embodiment, the operation display device 25 is mounted on the main body 21, but this is not limiting. For example, the cooking appliance 1 may be provided with a communication device for communicating with an external device, thereby receiving control instructions from the external device and controlling the heating unit 3 and additional function unit based on the received control instructions. Furthermore, the cooking menu selected for cooking, operation information of the heating unit 3, and device information of the additional function unit may be transmitted to the external device. The external device may be, for example, a terminal device such as a smartphone or PC owned by the user. The information display function of the terminal device and the communication function with the cooking appliance 1 are executed by an application program installed on the terminal device. The user can freely select the display content of the terminal device from the received operation information and device information. The operation information of the heating unit 3 includes the currently set heat power of the heating unit 3. Furthermore, the user can update the displayed content by sending a request to the cooking appliance 1 to send operation information and device information at any timing.

[0040] It is also desirable that contactless power supply is possible at the connection between the common mechanism unit 5 and the cooking unit 2. By using a contactless power supply system, it is possible to prevent moisture overflowing from the container P from entering the inside of the main body 21, which could cause breakdowns in the cooking appliance 1, and it is also possible to improve the ease of cleaning.

[0041] Moreover, the common mechanism 5 may be omitted, and the additional function units may be directly connected to the main body 21. In this case, each additional function unit communicates directly with the control device 7, and the processing of the additional function unit is executed. The function of the device control unit 53 of the common mechanism 5 described in the first embodiment is executed by the additional function unit or the control device 7.

[0042] Furthermore, in the first embodiment, the cooking appliance 1 is described as performing heating control based on the detection result of the bottom temperature sensor 4, but the bottom temperature sensor 4 does not necessarily have to be provided in the cooking appliance 1. If an in-container temperature sensor 6 is provided as an additional function unit, the control unit 71 of the control device 7 can control the heating unit 3 based on the in-container temperature sensor 6, regardless of the detection result of the bottom temperature sensor 4. Furthermore, even if neither the bottom temperature sensor 4 nor the in-container temperature sensor 6 is provided, the control unit 71 can control the heating unit 3 by predetermining the time for each cooking step in the cooking sequence for each menu.
