(embodiment mode 1)

A heating cooker according to embodiment 1 of the present disclosure will be described below with reference to fig. 1 to 4. Fig. 1 is a perspective view of a heating cooker 1 according to embodiment 1 of the present disclosure. Fig. 2 is a diagram illustrating the structure of heating cooker 1 according to embodiment 1. Fig. 3 is a plan view of heating cooker 1 according to embodiment 1. Fig. 4 is a block diagram showing a control system of the heating cooker 1. In the drawings, the X-axis direction represents the width direction of the heating cooker, the Y-axis direction represents the front-rear direction, and the Z-axis direction represents the height direction. In addition, the positive direction of the X axis is the right direction, and the negative direction is the left direction.

As shown in fig. 1, the heating cooker 1 is installed in, for example, a system kitchen BK. The system kitchen BK includes, for example, a heating cooker 1, a cooking table Ct, a water tank SK, and a range hood 17. Wall surface 18 is disposed on the back side of cooking device 1, cooking table Ct, and water tank SK. The range hood 17 is attached to the wall surface 18 so as to be positioned above the heating cooker 1. The range hood 17 sucks air above the heating cooker 1 into the inside by a built-in fan, and exhausts the air from a discharge port communicating with the outside. A wall surface 18A is disposed on the left side facing the heating cooker 1. The system kitchen BK is provided at, for example, the corners of an L-shape formed by the wall surfaces 18 and 18A.

As shown in fig. 2 and 3, the heating cooker 1 includes a main body 3 and a top unit 5 as an upper side portion of the main body 3. The top unit 5 includes a top plate 5a on which a cooking container is placed, and a rear frame 5b disposed on the back side (Y direction side) of the top plate 5 a. The rear frame 5b is provided with an exhaust port 16. In addition, the container accommodates the cooking object.

In embodiment 1, the heating cooker 1 is an induction heating cooker. The heating cooker 1 includes a heating portion 7 and a circuit board 10 in the interior of a main body 3 below a container placement region in a top plate 5 a. The heating unit 7 includes heating coils 7A and 7B. The heating coils 7A and 7B generate an induction magnetic field for heating the container. The circuit board 10 supplies a high-frequency current to the heating coils 7A and 7B, and controls the amount of current flowing through the heating coils 7A and 7B.

The main body 3 includes an operation unit 9 for a user to operate the heating unit 7. The operation unit 9 is disposed on the front side of the top plate 5a of the heating cooker 1. The operation unit 9 is, for example, a touch key, a touch panel, a dial, a button, a knob, or the like. The circuit board 10 controls the start and stop of heating by the heating coils 7A and 7B and the heating power level in accordance with an operation instruction from the operation unit 9.

The main body 3 includes a display unit 11 for displaying information such as the heating power level from the heating unit 7 by characters or images, and a sound output unit 15 for notifying information related to heating by the heating unit 7 by sound. The display unit 11 is disposed on the front side of the top plate 5a of the heating cooker 1. The display unit 11 is, for example, a black-and-white liquid crystal panel having a band shape extending in the longitudinal direction of the top plate 5a, but may be a color liquid crystal panel. In embodiment 1, the display unit 11 and the operation unit 9 are integrated as a touch panel.

The heating cooker 1 is provided with a sound output unit 15 for outputting sound guidance to the user on the front side. The sound output unit 15 is, for example, a speaker.

A through hole 31 is provided in the longitudinal center of the rear frame 5 b. The through hole 31 openably and closably covers a lid 33 which is rotatable about the 2-axis. The lid 33 is rotationally driven about a 1 st rotation axis Ld extending in the longitudinal direction (X direction) by the lid driving portion 35, and rotationally driven about a 2 nd rotation axis Ls extending in the vertical direction (Z direction). The 1 st rotation axis Ld is disposed on the front side of the cover 33. Accordingly, since the closed cover 33 is rotationally driven so as to rise from the back side to the front side, light from the projector 41 described later is less likely to actually enter the eyes of the user. In addition, cooking contaminants become difficult to adhere to the projector 41. The lid driving unit 35 includes, for example, a 2-axis rotation mechanism and a stepping motor. The inner surface 33a of the lid 33 is mirror-finished.

The heating cooker 1 includes a projector 41 inside the main body 3. The projector 41 is disposed below the top plate 5a and the cover 33. An image is projected from a projection lens 41a of the projector 41 toward the inner surface 33a of the cover 33. The irradiated image is reflected by the inner surface 33a of the lid 33 and projected onto the wall surface 18 between the range hood 17 and the heating cooker 1. The light projecting lens 41a is, for example, a zoom lens, and the projector 41 may have a zoom adjustment mechanism (not shown) for the light projecting lens 41a, the zoom adjustment mechanism adjusting the projection magnification of the light projecting lens 41a in accordance with an operation from the operation unit 9.

The heating cooker 1 includes a fan 37 inside the main body 3. The wind generated by the fan 37 cools the circuit board 10 and also cools the light source unit 41b of the projector 41. The light source unit 41b is, for example, an LED or a laser. The air that cools the circuit board 10 and the projector 41 flows outside the heating cooker 1 through the air outlet 16.

The heating cooker 1 includes a control unit 51 and a storage unit 53. The storage unit 53 stores a video directory and audio information corresponding to a cooking program.

The control unit 51 can be realized by a semiconductor element or the like. The control unit 51 is a processing device configured by, for example, a microcomputer, a CPU, a microprocessor, a DSP, an FPGA, an ASIC, or the like. The control unit 51 may be configured by only hardware, or may be realized by combining hardware and software. The control unit 51 is configured to read and execute data and programs stored in a storage unit 53 such as a ROM, a RAM, a hard disk, and an SSD, thereby realizing various functions.

The control unit 51 includes a cooking state determination unit 51a, a video control unit 51b, and a lid drive control unit 51 c.

The cooking state determining unit 51a determines the cooking state on the top plate 5a and controls the progress of the cooking program according to the cooking state. The cooking program includes cooking steps required for cooking a single dish, and each cooking step includes cooking information such as cooking contents, heating amount, and heating time. A plurality of types of cooking programs are stored in the storage unit 53. The cooking state is, for example, a cooking process currently being executed. The heating amount is at least one of the heating power and the heating temperature.

For example, in the case of a cooking program of "hamburger", there are a preheating step of preheating a frying pan, a baking step of baking a surface, a turning-over step, a baking step of baking a back surface, and a finishing step. Each cooking process has cooking information that determines a heating time, a heating amount, and the like. The cooking program is not limited to the cooking process in the heating cooker 1, and may include a preparation process and the like. For example, in the case of a cooking program of "hamburger", the cooking program may include a step of cutting the material and a step of kneading meat in the hamburger.

The image list corresponding to these cooking programs is stored in the storage unit 53. For example, in the step of baking the surface, an image of a hamburger that becomes the baking color of the sample is stored, and in the kneading step, an image of a hamburger before baking is stored.

If the user selects an arbitrary cooking menu using the operation unit 9, the cooking state determination unit 51a reads out the corresponding cooking program from the storage unit 53 based on the input signal from the operation unit 9. The lid drive control unit 51c controls the drive of the lid drive unit 35 based on an input signal from the operation unit 9 to rotate the lid 33 to the standing state.

The cooking state determination unit 51a determines the progress of the cooking process based on the read cooking program, the output of the circuit board 10, and the like. The information of the cooking process is transmitted to the image control unit 51b, and the image control unit 51b selects and reads an image list corresponding to the cooking process from the storage unit 53 and transmits the image list to the projector 41. As described above, the video control unit 51b controls the selection and playback of the video directory, and changes the display of the video directory according to the cooking state.

The projector 41 causes the lid 33 to reflect the image of the read image list and project the image on the wall surface 18. Further, the lid drive control unit 51c rotates the lid 33 on the top plate 5a about the 2 nd rotation axis Ls extending in the vertical direction according to the image list. For example, when the contents of the video directory are "prepared" videos, the video directory includes information on the video direction in advance, and the lid drive control unit 51c controls the lid drive unit 35 so that the lid 33 faces the wall surface 18 on the cooking table Ct side based on the information. This causes the image "ready" to be shifted to the cooking table Ct side, and thus, the image can be easily viewed by the user standing in front of the cooking table Ct. The contents of the catalog are, for example, contents of a video catalog corresponding to each cooking process. In the case of a cooking process in which the wall surface 18 on the inside of the heating cooker 1 becomes difficult to see due to steam or the like from the container after the lid is removed, the lid body drive control unit 51c controls the lid body drive unit 35 so that the lid body 33 is rotated to the side of the wall surface 18A on the lateral side of the heating cooker 1. For example, by storing the information on the image direction in the storage unit 53 for each cooking step in advance, if the cooking state determination unit 51a detects that the lid is detached, the lid drive control unit 51c controls the drive amount of the lid drive unit 35 based on the detection result and the information on the image direction stored in the storage unit 53. This makes it possible to project the image list onto the lateral wall surface 18A of the heating cooker 1. The direction of the projected image list may be automatically set by the image control unit 51b or may be set by the user via the operation unit 9. The image control unit 51b adjusts the list of projected images so as to correct the distortion of the projected image caused by the rotation of the lid 33 in accordance with the rotation drive amount instructed to the lid drive unit 35 by the lid drive control unit 51 c. The projection direction changing unit that changes the projection direction of the image projected from the projector 41 may be the cover 33, may be configured by the cover 33 and the cover driving unit 35, or may be configured by the cover 33, the cover driving unit 35, and the cover drive control unit 51 c.

If the cooking state determination unit 51a determines that all cooking steps have ended, the cooking state determination unit 51a turns OFF the power supply of the projector 41. Further, the lid drive control portion 51c controls the lid drive portion 35 so that the lid 33 is closed. Thereby, the projection of the image list is completed.

As described above, the heating cooker 1 according to embodiment 1 includes the top plate 5a on which the container for accommodating the heating target is placed, the heating unit 7 that heats the container placed on the top plate 5a from below, and the projector 41 that is disposed below the top plate 5a and projects an image obliquely upward. Since the projector 41 is housed below the top plate 5a of the cooking device 1, the cooking device can be provided which can display the list of images and can be easily installed. Further, by using the projector 41 for displaying the image list, the space around the cooking device 1 is not narrowed even if the projection size of the image list is enlarged, and thus the image list can be made space-saving and easily viewed by the user.

(embodiment mode 2)

Next, a heating cooker 1A according to embodiment 2 will be described with reference to fig. 5 and 6. The heating cooker 1A according to embodiment 2 includes various sensors, and changes the projection direction of an image based on the detection results of the sensors. The heating cooker 1A according to embodiment 2 is common to the heating cooker 1 according to embodiment 1 except for the following matters.

A heating cooker 1A according to embodiment 2 includes human detection sensors 27 and 28 for detecting a position of a user, a temperature sensor 29 for detecting a temperature of a container or a cooking object in the container, a main body communication unit 39 for performing wireless communication, a microphone 45, and an imaging unit 55. The control unit 51 of embodiment 2 includes a voice recognition unit 51 d.

The human detection sensors 27 and 28 are proximity sensors, for example, and detect the presence of a user (human) in a short distance from the human detection sensors 27 and 28. The human body sensor 27 is disposed on the front surface side of the main body 3. The motion sensor 28 is disposed on the front side of the cooking table Ct, for example. The human detection sensors 27 and 28 can detect a user positioned in front of the heating cooker 1B and a user positioned in front of the cooking table Ct. Detection signals of the human detection sensors 27 and 28 are transmitted to the control unit 51. Further, the energy consumption amount of the human detection sensors 27 and 28 is relatively large. When the motion sensor 27 is disposed in the main body 3, energy is supplied from the power source of the heating cooker 1, and thus the operation can be stabilized.

When a detection signal indicating the presence of the user is input from the human detection sensor 27, the lid drive control unit 51c controls the lid drive unit 35 so that an image is projected onto the wall surface 18 on the back side of the heating cooker 1. Further, if a detection signal indicating the presence of the user is input from the human detection sensor 28, the lid driving unit 35 is controlled so that an image is projected onto the wall surface 18 on the back side of the cooking table Ct. As described above, the cover drive control unit 51c changes the projection direction of the image by controlling the rotation drive amount of the cover 33 in accordance with the position of the user.

The temperature sensor 29 is disposed at the center of the heating coils 7A and 7B below the top plate 5a, for example, to detect the temperature of the bottom of the container. The temperature detected by the temperature sensor 29 is sent to the control unit 51. Further, an infrared sensor may be attached to range hood 17 as temperature sensor 29 to detect the temperature of the cooking material in the container and the temperature of the container.

The imaging unit 55 includes a camera 57 and a communication unit 59 that transmits and receives data to and from the main body communication unit 39 of the main body 3 by wireless communication. For example, by disposing the imaging unit 55 in the range hood 17, the camera 57 can image the ceiling 5a and the periphery of the ceiling 5 a.

The camera 57 may be, for example, a visible light camera or a thermal image camera. The image information captured by the camera 57 is transmitted from the communication unit 59 to the control unit 51 via the main body communication unit 39 of the main body 3.

When the human detection sensor 27 detects that the user is positioned in front of the heating cooker 1, the lid drive control unit 51c projects the list of images onto the wall surface 18 on the back side of the heating cooker 1. When the user is detected by the motion sensor 28 to be positioned in front of the cooking table Ct, the lid drive control unit 51c controls the drive amount of the lid drive unit 35 to change the projection position so that the list of images is projected onto the wall surface 18 on the back side of the cooking table Ct. As described above, the cover drive control unit 51c changes the projection direction of the video image according to the position of the user based on the detection result by the human detection sensor.

If the cooking state determining unit 51a determines that the cooking state has changed based on the temperature detected by the temperature sensor 29, the image control unit 51b projects an image list of the next cooking program based on the determination result. If the next list of images is contents to be cooked with the lid of the container opened, for example, the cooking state determining unit 51a may not be visible due to the steam, and instructs the lid drive control unit 51c to change the projection position according to the progress state of the cooking program. The lid drive control unit 51c controls the drive amount of the lid drive unit 35 and rotates the lid 33 in accordance with the instruction from the cooking state determination unit 51 a. As described above, the lid drive control unit 51c changes the projection direction of the image according to the cooking state.

In addition, the cover drive control unit 51c may change the projection direction by controlling the drive amount of the cover drive unit 35 in accordance with the operation amount received by the operation unit 9 in response to the user's instruction to the operation unit 9 serving as the instruction receiving unit. Further, the projection direction may be changed according to a voice instruction of the user. For example, the voice of the user is picked up by the microphone 45 as the instruction receiving unit, and the voice information obtained by the picking up is transmitted to the voice recognition unit 51 d. The voice recognition unit 51d recognizes the user's instruction from the voice information, and transmits the recognized user's instruction to the cover drive control unit 51 c. As described above, the cover drive control unit 51c may change the projection direction by controlling the drive amount of the cover drive unit 35 based on the user instruction.

According to the heating cooker 1A of embodiment 2, the projection direction is changed based on the detection results of various sensors. The heating cooker 1A may include all of the human detection sensors 27 and 28, the temperature sensor 29, the microphone 45, and the imaging unit 55, or may include any of them. In addition to these sensors, for example, an overflow sensor may be provided, and when an overflow is detected, the projector 41 may be controlled so that the image control unit 51b temporarily stops the projection of the image list. Alternatively, the projection direction may be changed according to the image information captured by the camera 57. For example, the cooking state determination unit 51a may detect steam based on image information captured by the camera 57 and change the projection direction. Alternatively, the projection may be temporarily stopped based on the image information captured by the camera 57. For example, the cooking state determination unit 51a may detect an overflow from the image information captured by the camera 57 and change the projection direction.

(embodiment mode 3)

Next, a heating cooker 1B according to embodiment 3 will be described with reference to fig. 7. The heating cooker 1B according to embodiment 3 can access the mobile terminal 61 and download the cooking program and the video directory via the mobile terminal 61. A heating cooker 1B according to embodiment 3 is common to the heating cooker 1 according to embodiment 1 except for the following matters.

The heating cooker 1B according to embodiment 3 includes a main body communication unit 39 and performs wireless communication with the mobile terminal 61. The main body communication unit 39 and the terminal communication unit 63 of the portable terminal 61 each have an antenna and are connected by standard wireless communication such as Wi-Fi (registered trademark), Bluetooth (registered trademark), BLE (registered trademark) Low Energy, or 5G.

The portable terminal 61 is, for example, a smartphone or a tablet terminal. The cooking device includes a terminal communication unit 63 that performs wireless communication with the cooking device 1B, an operation unit 65, an audio output unit 66, a display unit 67, a storage unit 68, and a terminal control unit 69 that controls these units. The terminal communication unit 63 is also communicably connected to a server 71 via the internet 70 or the like by wireless communication.

The sound output unit 66 is, for example, a speaker. The display unit 67 is, for example, a touch panel display, and may have the function of the operation unit 65. The terminal control unit 69 is a processing device such as a CPU or a microprocessor, for example, and is configured to implement various functions by executing an application program stored in the storage unit 68 such as a ROM, a RAM, a hard disk, or an SSD.

Next, a method of projecting the video list of the cooking menu acquired from the server 71 will be described with reference to fig. 8. Fig. 8 is a flowchart showing a processing procedure of projecting the image list of the cooking menu downloaded from the server.

In step S1, the heating cooker 1B and the mobile terminal 61 are wirelessly connected. The main body communication unit 39 of the heating cooker 1B and the terminal communication unit 63 of the portable terminal 61 can perform bidirectional communication.

The mobile terminal 61 is previously loaded with application software for the heating cooker 1B by downloading or the like. The user can operate the heating cooker 1B by operating the operation unit 65 of the mobile terminal 61 by activating the application software. In step S2, the user instructs the projector 41 to start using the operation unit 65 of the portable terminal 61. The start signal is input from the operation unit 65 to the video control unit 51b via the terminal communication unit 63 and the main body communication unit 39. The video control unit 51b starts the projector 41 based on the input start signal.

The portable terminal 61 is connected to a server 71 via the internet 70. The server 71 stores various cooking menus. In step S3, the user downloads data of a preferred cooking menu from the server 71 to the mobile terminal 61 by using the application software of the mobile terminal 61, and stores the data in the storage unit 68.

In step S4, the cooking menu data downloaded to the mobile terminal 61 is transmitted from the mobile terminal 61 to the heating cooker 1B. The heating cooker 1B stores the received cooking menu data in the storage unit 53.

The user starts the guidance of the downloaded cooking menu. In step S5, the video control unit 51b transmits the video list corresponding to each cooking process of the cooking menu to the projector 41, and the projector 41 projects the video list on the wall surface 18.

The contents downloaded from the server 71 are not limited to the information of the cooking menu, and the contents may be simply downloaded as a video directory.

The present disclosure is not limited to the above-described embodiments, and can be modified as follows.

(1) In the above embodiment, the image directory is projected on the wall, but is not limited thereto. For example, as shown in fig. 13, the screen 19 may be provided when there is no wall surface 18 but a window or a space between the range hood 17 and the heating cooker 1. The screen 19 may be a cloth scroll screen, or may be a disposable screen that can be replaced when contaminated with oil, for example. In addition, when the image is difficult to see due to the color of the wall surface, a white screen may be attached to the wall surface. As for the attachment type screen 19, for example, one side is a light scattering layer and the other side is an adhesive layer. The screen 19 includes at least a light reflecting layer between the light scattering layer and the adhesive layer.

(2) In the above embodiment, the projector 41 projects an image by reflecting the image by the cover 33, but the invention is not limited thereto. The projector 41 may project the image directly without reflecting the image by the cover 33. As shown in fig. 14, the direct projection may be performed through the rear frame 5b or the top plate 5a of the top unit 5. The back frame 5b or the top plate 5a through which the image catalog is transmitted is a colorless transparent member, such as tempered glass. In this case, the projection direction may be rotated by allowing the projector 41 itself to rotate. Further, a cover glass different from the top plate 5a may be fitted to the rear frame 5b or the top plate 5a, and the image may be projected by transmitting light through the cover glass. Further, a part of the projector 41, for example, the light projecting lens 41a may be projected from the rear frame 5b or the top plate 5a, and light may be projected directly toward the wall surface 18 from the projected part. The protruding portion may be rotatable about a vertical axis or movable up and down in the vertical direction. The protruding portion may be covered with a dome-shaped or cylindrical cover. The dome-shaped or cylindrical cover may be configured to transmit light partially or entirely.
