FIG. 3 is an exploded perspective view of the lid body 2. 4 and 5 are vertical sectional views showing the internal structure of the electric cooker 1 of FIG. 1. The structure of the electric cooker 1 is demonstrated with reference to these figures.

As shown in FIG. 1, the electric cooker 1 includes an electric cooker body (cooker body) 3 and a cover 2 attached to an upper portion of the electric cooker body 3. As shown in FIG. 2, the lid body 2 can be completely separated from the electric cooker main body 3. The electric cooker 1 is configured to be used not only for cooking rice, but also for cooking, steaming, and the like. In addition, although not shown in the figure, the electric cooker main body 3 is provided with a power cord that can be drawn out around a reel.

The lid body 2 is provided with an operation portion 23 for performing a rice cooking operation of the electric cooker 1. The operation unit 23 is configured by a touch panel type liquid crystal display panel. Thereby, the user can perform a rice cooking operation of the electric pot 1 by performing a touch operation on an operation button or the like displayed on the liquid crystal display panel. In addition, a touch panel type organic EL panel may be used instead of a touch panel type liquid crystal display panel. The operation unit 23 may be a portion provided with an operation button and a display panel for displaying information on the surface of the cover 2.

The operation unit 23 requires power supply and transmission and reception of control signals for controlling the electric pan 1. The electric power is supplied from the electric pot main body 3. In addition, control signals are transmitted and received between the cover 2 and the electric cooker main body 3. Generally, the above-mentioned power supply and control signal transmission and reception are performed by wire. However, as shown in FIG. 2, in the electric cooker 1 of this embodiment, the cover body 2 can be completely separated from the electric cooker main body 3.

Wireless power supply is performed between the wireless power supply part 5a of the cover 2 and the wireless power supply part 5b of the electric pot main body 3. The non-contact communication is between the non-contact communication part 6a of the cover 2 and the non-contact communication part 6b of the electric pot main body 3. Between. Details of wireless power supply and contactless communication will be described later.

In this way, by realizing wireless power supply and non-contact communication, wiring that has been conventionally required can be eliminated, so that there is no restriction on the appearance design due to wiring. Therefore, it is possible to realize the electric cooker 1 with a priority in design.

(Cover 2)
As shown in FIGS. 2 and 3, the lid body 2 includes an outer lid 21 covering the upper surface of the electric cooker main body 3 and an inner lid 22 covering the inner pot 4. Here, as shown in FIG. 3, the inner cover 22 and the outer cover 21 are formed completely independently. When the outer cover 21 is removed from the electric pot main body 3, as shown in FIG. 2, the inner pot 4 is maintained with the lid closed. status.

When the lid body 2 covers the electric pot main body 3, the inner pot 4 is first covered by the inner cover 22, and is arranged to cover the inner cover 22 through the outer cover 21 from above. A grip portion 22 a is formed on the surface of the inner cover 22 so as to be grasped by a user in a substantially cylindrical shape. In addition, an opening portion 21a is formed in the outer cover 21, and when the inner cover 22 is placed in a predetermined position on the electric pot main body 3 with the inner pot 4 covered, the grip of the inner cover 22 is embedded. Hand 22a. In other words, when the lid body 2 is provided on the electric cooker main body 3, the handle portion 22 a of the inner lid 22 that covers the inner pot 4 is fitted with the opening portion 21 a of the outer lid 21. This position is set to the correct position where the lid body 2 is installed on the electric cooker main body 3.

Normally, when cooking is started with the electric pan 1, steam is generated in the inner pan 4. In order to escape the steam generated in the inner pot 4, a steam hole is provided in the lid body 2. Specifically, if the steam port 22c is formed in the grip portion 22a of the inner cover 22, steam can escape from the opening portion 21a of the outer cover 21 from which the grip portion 22a is exposed. In other words, in the lid 2, the opening portion 21 a formed in the outer lid 21 functions as a steam port of the electric cooker 1.

Therefore, as in the above-mentioned structure, the handle portion 22a is provided with a steam port 21c for releasing steam generated from the inner pot 4, so that it is not necessary to separately provide the inner lid 22 and the outer lid 21 for steam to escape. In the steam port, the grip portion 22 a is provided in the inner cover 22 and is exposed from the opening portion 21 a formed in the outer cover 21.

In addition, since the number of openings formed in the outer cover can be reduced, the appearance of the cooker body is good.

An operation portion 23 is provided near the vapor port of the lid 2, that is, near the opening portion 21 a, in which a rice cooking method, a cooking name, and the like are displayed in liquid crystal, and an operation instruction is performed by touch. As described above, the information displayed on the operation unit 23 and the touch signals that have been touched are transmitted through non-contact communication between the cover 2 and the electric pot main body 3. In addition, the power is supplied to the operation unit 23 by the wireless power supply between the cover 2 and the electric pot main body 3 as described above.

(Wireless power supply, contactless communication)
In order to achieve wireless power supply, a wireless power supply section 5a is provided in the cover 2 and a wireless power supply section 5b is provided in the electric pot main body 3. As shown in FIG. 4, the wireless power supply unit 5 a and the wireless power supply unit 5 b are provided at positions where power can be supplied to the cover body 2 from the side of the pot body 3 in a state where the cover body 2 is provided at a predetermined position of the pot body 3. .

On the other hand, in order to achieve non-contact communication, the cover body 2 is provided with a non-contact communication portion 6a, and the cover body 2 is provided with a non-contact communication portion 6b. As shown in FIG. 4, the non-contact communication section 6 a and the non-contact communication section 6 b are provided so that the cover 2 can be installed between the cover 2 and the electric pot body 3 in a state where the cover 2 is provided at a predetermined position of the electric pot body 3. Where information is sent and received.

In this embodiment, an electromagnetic induction method is used as wireless power supply, and an infrared communication (IR) transmission method is used as non-contact communication. However, wireless power supply and non-contact communication are not limited to these methods, as long as the power supply and information transmission and reception can be performed wirelessly in a state where the cover body 2 is provided at a predetermined position of the electric pot main body 3. , It can be any way.

As shown in FIGS. 4 and 5, an induction coil 7 for inductively heating the inner pot 4 is provided in the inner pot 4. The induction coil 7 is an example of a heating section.

The inner pot 4 is formed of, for example, a high thermal conductivity material such as aluminum, and a magnetic body such as stainless steel for improving heating efficiency is adhered to an outer surface thereof. On the other hand, an inner surface is coated with a fluororesin for preventing adhesion of contents.

(Control System)
The control system of the electric cooker 1 is demonstrated. FIG. 6 is a block diagram showing a configuration of a control circuit provided in the cover 2. FIG. 7 is a block diagram showing a configuration of a control circuit provided in the electric cooker main body 3.

First, a control circuit of the lid body 2 will be described. As shown in FIG. 6, the cover 2 is a main part of the control system and includes a CPU 10, a ROM (Read Only Memory) 14, and a RAM (Random Access Memory) 15. In addition, the CPU 10 is connected to a cooking control section 13, a non-contact communication section 6 a, a wireless power supply section 5 a, a communication state determination section 11, a power measurement section 12, and an operation section 23.

The CPU 10 controls each unit by executing a control program (program) stored in the ROM 14. Specifically, the CPU 10 performs: display control of the operation unit 23; control of receiving operations and instructions from the cooking control to the cooking control unit 13; determination of the communication state of the non-contact communication unit 6a based on the communication state determination unit 11, Control and the like based on the determination of the power supply state of the wireless power supply unit 5 a of the power measurement unit 12.

Next, a control circuit of the electric cooker body 3 will be described. As shown in FIG. 7, the electric cooker main body 3 includes a CPU 40, a ROM 44, and a RAM 45 as main parts of a control system. In addition, the CPU 40 is connected to a non-contact communication section 6b, a wireless power supply section 5b, a communication state determination section 41, an induction coil 7, and a forced stop section 46.

The CPU 40 controls each unit by executing a control program stored in the ROM 44. Specifically, the CPU 40 receives the instruction signal from the cooking control unit 13 of the cover 2 by using the non-contact communication unit 6 b, thereby performing on / off control of the induction coil 7 and non-contact communication by the communication state determination unit 41. The communication state determination control of the unit 6b, the power supply control of the wireless power supply unit 5b, the forced stop control by the forced stop unit 46, and the like.

A power source 42 is connected to the wireless power supply unit 5b. The power source 42 is realized by inserting a power cord that can be drawn out around a reel built in the electric cooker main body 3 into a household outlet.

A stop switch 47 is connected to the forced stop unit 46. When the stop switch 47 is turned on, the cooking operation can be forcibly stopped even when the control of the electric pot main body 3 by the operation section 23 of the lid 2 is not possible. This stop switch 47 is provided separately from a switch for turning on / off the power supply provided in the operation unit 23 of the electric cooker 1 and is formed at a position that is not easily touched by a user during normal use (for example, the electric cooker main body 3 Back side, etc.).

(Notice of misplacement)
When the lid body 2 is attached to the electric cooker main body 3, the inner pot 4 accommodated in the electric cooker main body 3 is covered with the inner lid 22 first. The outer cover 21 is provided at a predetermined position of the electric cooker main body 3 so as to cover the inner cover 22. If the outer cover 21 is not appropriately provided at a predetermined position with respect to the electric pot main body 3, non-contact communication and wireless power supply cannot be performed properly. Therefore, as shown in FIG. 6, the control circuit of the cover 2 is provided with a communication state determination unit 11 that determines the communication state of non-contact communication, and a power measurement unit 12 that determines the power supply state of wireless power supply. Here, the CPU (cover misalignment determination unit) 10 has no problem as long as all the determination results based on the communication state determination unit 11 and the power measurement unit 12 are appropriate, and even if some of the determination results are inappropriate (communication Error, power supply error), an error notification is delivered to the user for that purpose. Specifically, it is conceivable to cause the operation unit 23 to display an error, for example, to display a content such as "the cover is not in an appropriate position", to broadcast the above-mentioned content by voice, and to notify by a warning sound.

Here, each of the communication state determination unit 11 and the power measurement unit 12 determines the communication state and the power supply state based on signals received by the non-contact communication unit 6a and the wireless power supply unit 5a. Therefore, when the receiving surface / transmitting surface of the non-contact communication portion 6a and the wireless power supply portion 5a are contaminated with cooking soup or the like, signals cannot be properly transmitted and received. In other words, even if the lid body 2 is provided at an appropriate position with respect to the electric cooker main body 3, it is determined that the determination results of the communication state determination unit 11 and the power measurement unit 12 are not appropriate, and the user is notified that "the lid body is not present." The right place ".

In order to avoid such a situation, in this embodiment, the transmitting section, the receiving section, and the wireless power supply section 5a of the non-contact communication section 6a of the cover body 2 are provided at a distance from each other. The transmitting section, the receiving section, and the wireless power supply section 5b of the non-contact communication section 6b are provided so as to be separated from each other. Thereby, the displacement of the cover body 2 can be detected at three positions.

For example, if there is a communication error (power supply error) in one of the three locations, it is determined to be a communication error due to stains due to ingredients and soups in that location. If there is a communication error in more than two locations ( Power supply error), it is determined that the cover 2 is not set in an appropriate position, and the user is notified of the purpose.

(effect)
According to the electric cooker 1 configured as described above, when the lid body 2 is removed from the electric pot main body 3, only the outer lid 21 is removed from the electric pot main body 3, and the inner lid 22 is maintained in a state where the inner pot 4 is covered. Therefore, when the outer lid 21 is opened, there is no concern that the condensed water on the surface of the inner lid 22 hangs around the inner pot 4 and the inner pot 4.

In addition, according to the electric cooker 1 having the above-mentioned configuration, since there is no need for power supply wiring and signal transmission wiring between the cover 2 and the electric pot main body 3, problems such as disconnection due to aging and deterioration of the wiring do not occur. In addition, since the lid body 2 can be completely removed from the electric cooker main body 3, cleaning of the electric cooker 1 can be facilitated. Furthermore, since it is not restricted by the external design caused by the wiring required between the cover and the main body of the electric cooker as in the past, it is possible to realize an electric cooker that gives priority to the external design.

In the first embodiment described above, an example has been described in which a user operates the stop switch 47 shown in FIG. 7 to forcibly stop the cooking operation. In the following second and third embodiments, an example of stopping control of a rice cooking operation using a power supply state and a communication state during cooking of an electric pan will be described. In addition, in the second and third embodiments described below, the cover body may be completely separated from the inner cover as in the first embodiment described above, or the inner cover may be detachably installed outside. cover. In addition, a cover body in which the inner surface of the outer cover doubles as the inner cover may be used.

[Second Embodiment]
Hereinafter, one embodiment of the present invention will be described in detail. The configuration of the electric cooker 1 is the same as that of the first embodiment. The difference is that the stop state of the cooking operation of the electric cooker 1 is controlled by using the communication state of the non-contact communication part 6a of the cover body 2 and the electric pot main body 3 based on the non-contact communication of the non-contact communication part 6b.

(Stop control of cooking action)
When the rice cooking operation by the electric cooker 1 is started, the communication state by the non-contact communication unit 6 a is determined by the communication state determination unit 11 provided in the lid 2. At the same time, the communication state determination unit 41 provided in the electric pot main body 3 also determines the communication state by the non-contact communication unit 6b.

Specifically, the communication state determination unit 11 determines whether the signal level of the signal received by the contactless communication unit 6a is equal to or less than a predetermined value. At the same time, the communication state determination unit 41 also determines whether the signal level of the signal received by the contactless communication unit 6b is equal to or lower than a predetermined value. Here, when it is determined by the communication state determination unit 11 and the communication state determination unit 41 that the signal level is equal to or less than a predetermined value, it is determined that the non-contact communication unit 6a and the non-contact communication unit 6b cannot properly communicate. . In this case, the control signal for controlling the rice cooking operation currently in progress in the electric pot main body 3 cannot be appropriately implemented in the electric pot main body 3, and therefore, if the rice cooking operation is performed as it is, the rice cannot be cooked smoothly. . Therefore, the CPU 40 of the electric cooker main body 3 gives an instruction to the forced stop section (stop section) 46 to forcibly stop the rice cooking operation.

That is, in the electric cooker 1 having the above-mentioned configuration, when the communication state of the non-contact communication transmitting and receiving control signals deviates from the predetermined communication state during the cooking operation, that is, when the signal level of the signal of the non-contact communication becomes below a predetermined value. The forcible stopping unit 46 stops the rice cooking operation of the electric pot main body 3.

Accordingly, when the non-contact communication is not properly performed during the rice cooking operation, it is possible to stop the operation of only the electric pot main body 3.

In addition, confirmation of the communication state of the non-contact communication is performed at intervals of several seconds during the rice cooking operation. However, the confirmation of the communication status is not limited to being performed periodically, and may be performed continuously or irregularly.

In addition, when the communication state is degraded during the rice cooking operation and the rice cooking operation is stopped, a warning sound or the like is reported to the user.

When it is difficult to recover the non-contact communication due to the failure of the electric pot 1, it is necessary to completely stop the rice cooking operation of the electric pot body 3. However, in a case where the non-contact communication is temporarily unavailable and immediately resumes, the rice cooking operation of the electric pot main body 3 may be restarted. At this time, the state immediately before the cooking operation of the electric pot main body 3 is stopped (in the middle of the cooking process) is resumed. The state immediately before the rice cooking operation is stopped is stored in the RAM 45 of the CPU 40 in advance, and can be read out when it is started again.

In the description so far, the communication state of non-contact communication is used to stop the rice cooking operation of the electric pot main body 3. However, in the following third embodiment, the rice cooking operation is performed on the power supply state using wireless power supply. An example of stopping will be explained.

[Third Embodiment]
Hereinafter, one embodiment of the present invention will be described in detail. The configuration of the electric cooker 1 is the same as that of the first embodiment. The difference lies in that stop control of the cooking operation of the electric cooker 1 is performed by using the power supply states of the wireless power supply section 5a of the cover 2 and the wireless power supply section 5b of the electric pot main body 3.

(Stop control of cooking action)
When the rice cooking operation based on the electric pan 1 is started, the power measurement state of the wireless power supply using the wireless power supply unit 5a and the wireless power supply unit 5b is determined by the power measurement unit 12 provided in the lid body 2.

Specifically, the power measurement unit 12 determines whether the power level received by the wireless power supply unit 5a is equal to or less than a predetermined value. Here, when it is determined by the power measurement unit 12 that the power level is equal to or less than a predetermined value, it is determined that wireless power supply is not performed properly. In this case, since sufficient power is not supplied to the operation portion 23 of the lid body 2, an appropriate instruction cannot be given to the electric pot body 3.

Therefore, from the lid body 2 to the electric cooker main body 3, a signal indicating that wireless power supply is not properly performed is transmitted from the operation section 23 to the CPU 40 of the electric cooker main body 3. The CPU 40 gives an instruction to the forced stop section (stop section) 46 and Force the cooking operation to stop.

That is, in the electric cooker 1 configured as described above, when the power supply state of the wireless power supply is deviated from the predetermined power supply state during the cooking operation, that is, when the power level of the wireless power supply is below a predetermined value, the forced stop unit 46 is used to The cooking operation of the electric pot main body 3 is stopped.

Accordingly, in a case where wireless power supply cannot be performed properly during the rice cooking operation, only the electric pot main body 3 can be kept from operating.

The confirmation of the power supply status of the wireless power supply is performed at intervals of several seconds during the rice cooking operation. However, the confirmation of the power supply state is not limited to being performed periodically, and may be performed continuously or irregularly.

In addition, when the power supply state is degraded during the rice cooking operation and the rice cooking operation is stopped, the user is notified by a warning sound or the like.

When it is difficult to restore the non-contact communication due to the failure of the electric pot 1, it is necessary to completely stop the rice cooking operation of the electric pot body 3. However, in a case where the wireless power supply is temporarily unavailable and immediately resumed, the cooking operation of the electric pot main body 3 may be restarted. At this time, the state immediately before the cooking operation of the electric pot main body 3 is stopped (in the middle of the cooking process) is resumed. The state immediately before the rice cooking operation is stopped is stored in the RAM 45 of the CPU 40 in advance, and can be read out when it is started again.

In addition, in the first to third embodiments, the electric cooker has been described as an example of the cooking device of the present invention, but it is not limited to this, and other heating cooking devices may also be used. Unheated cookers, such as warmers.

[Example of software-based implementation]
The control block (especially the cover misalignment detection circuit) of the electric cooker 1 can be realized by a logic circuit (hardware) formed in a integrated circuit (IC chip) or the like, or a CPU (Central Processing Unit) and software .

In the latter case, the electric cooker 1 includes a CPU that executes software, that is, a program command that implements each function, a ROM (Read Only Memory) that records the above program and various data in a manner that can be read by a computer (or CPU), or A storage device (referred to as a "recording medium"), and a RAM (Random Access Memory) on which the above-mentioned program is developed. The computer (or CPU) reads and executes the program from the recording medium, thereby achieving the object of the present invention. As the recording medium, a “non-transitory tangible medium” such as a tape, a disc, a card, a semiconductor memory, a programmable logic circuit, or the like can be used. The program may be supplied to the computer via an arbitrary transmission medium (communication network, broadcast wave, etc.) capable of transmitting the program. In addition, the present invention can also be implemented by electronically transmitting a data signal embedded in a carrier wave by embodying the program described above.
