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

  As shown in FIG. 1, the rice cooker 1 includes a rice cooker body (cooker body) 3 and a lid 2 attached to the top of the rice cooker body 3. The lid 2 can be completely separated from the rice cooker body 3 as shown in FIG. The rice cooker 1 is configured to be used not only for cooking rice but also for cooking such as boiled food and steamed food. In addition, although not shown in figure, the rice cooker main body 3 is provided with the power cord wound around the cord reel so that it can be pulled out.

  The lid 2 is provided with an operation unit 23 for performing the rice cooking operation of the rice cooker 1. The operation unit 23 is configured by a touch panel type liquid crystal display panel. Thereby, the user can perform the rice cooking operation of the rice cooker 1 by touch-operating the operation button etc. which were displayed on the liquid crystal display panel. Note that a touch panel organic EL panel may be used instead of the touch panel liquid crystal display panel. The operation unit 23 may be provided with an operation button and a display panel for displaying information on the surface of the lid 2.

  The operation unit 23 requires power supply and transmission / reception of a control signal for controlling the rice cooker 1. Electric power is supplied from the rice cooker body 3. Moreover, transmission / reception of a control signal is performed between the cover body 2 and the rice cooker main body 3. FIG. Generally, power supply and transmission / reception of control signals are performed by wire, but in the rice cooker 1 according to the present embodiment, the lid 2 is completely separated from the rice cooker body 3 as shown in FIG. Since it is configured so as to be able to perform power transmission by wireless power feeding, control signals such as cooking signals by non-contact communication are transmitted and received. Wireless power feeding is performed between the wireless power feeding unit 5a of the lid 2 and the wireless power feeding unit 5b of the rice cooker body 3, and non-contact communication is performed between the non-contact communication unit 6a of the lid 2 and the rice cooker body 3 non-contact. This is performed with the contact communication unit 6b. Details of wireless power feeding and non-contact communication will be described later.

  As described above, by realizing wireless power feeding and non-contact communication, it is possible to eliminate wiring that has been necessary in the past, and thus it is possible to eliminate restrictions on design due to wiring. Therefore, it becomes possible to realize the rice cooker 1 giving priority to design.

(Cover body 2)
As shown in FIGS. 2 and 3, the lid 2 includes an outer lid 21 that covers the upper surface of the rice cooker body 3 and an inner lid 22 that covers the inner pot 4. Here, as shown in FIG. 3, the inner lid 22 is formed completely independently of the outer lid 21, and when the outer lid 21 is removed from the rice cooker body 3, as shown in FIG.

The two fixing portions 310 are provided at positions facing each other in the rice cooker 301. Note that the number of fixing portions 310 is not limited to two, and may be three or more. Moreover, if it is only the objective of fixing the cover body 302 to the rice cooker main body 303, the one fixing | fixed part 310 may be sufficient.

(Description of the fixing part 310)
FIG. 11 is a diagram for explaining the structure and operation of the fixing portion 310.

  The fixing part 310 is a latch as shown in FIG. In other words, the fixed portion 310 includes a locking bar 311, a spring 312, and a rotating shaft 313.

  The spring 312 is installed in a recess 303a formed on the side surface of the rice cooker body 303 so that a biasing force acts in the horizontal direction.

  The rotation shaft 313 is provided above the installation portion of the spring 312 of the recess 303a. The rotating shaft 313 is configured to pivotally lock the locking bar 311 toward the side surface of the rice cooker body 303.

  The locking bar 311 has a protruding shape so that the tip 311 a can be locked to a recess 302 a formed on the side surface of the lid 302. The rear end 311 b of the locking bar 311 is in contact with the spring 312. Due to the urging force of the spring 312, the locking bar 311 rotates around the rotation shaft 313 so that the tip 311 a faces the side surface of the lid 302. At this time, as shown in FIG. 11A, the distal end portion 311a of the locking bar 311 is locked by the concave portion 302a formed on the side surface of the lid 302, so that the fixing portion 310 is locked. .

  When releasing the locked state of the fixing portion 310 shown in (a) of FIG. 11, as shown in (b) of FIG. By holding the spring 312 against the urging force, the locking bar 311 rotates around the rotation shaft 313, and the tip 311 a is detached from the recess 302 a of the lid 302. Thereby, the locked state of the fixing | fixed part 310 is cancelled | released.

  In addition, in this embodiment, although the latch was demonstrated to the example as the fixing | fixed part 310, it is not limited to this, A projection part is provided on the rice cooker main body 303, and the rice cooker main body 303 of the cover body 302 is opposed. You may provide the fitting hole which the said projection part fits in a position. The shape of the protrusion in this case is not particularly limited, and the fitting hole may be a shape that matches the shape of the protrusion.

  As described above, when the protrusion 310 is used as the fixing portion 310, there is an effect that cleaning is easier than in the case of a complicated structure such as a latch.

  However, when the rice cooker 301 is a pressure type, it is necessary to prevent the lid 302 from being detached from the rice cooker main body 303. Therefore, the fixing unit 310 is preferably a latch as shown in FIG.

(effect)
According to the said structure, there is no possibility that the cover body 302 may remove | deviate from the rice cooker main body 303 by external force during rice cooking by providing the fixing | fixed part 310 which fixes the cover body 302 to the rice cooker main body 303 so that attachment or detachment is possible.

  Moreover, in order to fix the cover body 302 to the rice cooker main body 303 reliably, as above-mentioned, it is preferable to provide the fixing | fixed part 310 two or more.

  In embodiment so far, there exists a possibility that a communication state may deteriorate by the aged deterioration of the non-contact communication part 6a and the non-contact communication part 6b which implement | achieve the non-contact communication in a rice cooker. In particular, when an LED is used as a light emitting element for non-contact communication, the communication state may be deteriorated due to a decrease in the amount of emitted light due to deterioration of the LED over time. In addition, the amount of light emitted from the LED decreases even at high temperatures.

  Embodiment 4 below describes an example in which contactless communication is performed in consideration of a decrease in the amount of emitted light due to aging of an LED as a light emitting element and a decrease in the amount of emitted light due to a high temperature.

[Embodiment 4]
Another embodiment of the present invention will be described below. For convenience of explanation, members having the same functions as those described in the above embodiment are given the same reference numerals, and the description thereof will not be repeated.

(Outline of rice cooker 401)
FIG. 12 is a schematic view of a rice cooker 401 according to the present embodiment.

  The rice cooker 401 includes a lid body 402 and a rice cooker body 403. The rice cooker 401 has substantially the same configuration as the rice cooker 1 of the first embodiment, the lid 402 is the same as the lid 2, and the rice cooker main body 403 is the same as the rice cooker main body 3. The difference between the rice cooker 401 and the rice cooker 1 is that the lid 402 includes a temperature sensor 405a and an LED control unit 406a, and the rice cooker body 403 includes a temperature sensor 405b and an LED control unit 406b.

  Moreover, in this embodiment, the non-contact communication parts 6a and 6b are provided with LED communication, ie, all are provided with the LED light emission part in the transmission side, and the light-receiving part in the reception side.

  The amount of light emitted from the LED on the transmission side decreases due to deterioration over time. Even at high temperatures, the amount of light emitted by the LED decreases. In cooking utensils such as rice cookers, the temperature inside the machine becomes high during use, and the communication characteristics deteriorate due to a decrease in the amount of light. Therefore, in the present embodiment, the following countermeasures prevent communication characteristics from deteriorating in consideration of a decrease in the amount of emitted light due to aging degradation of the LED and a decrease in the amount of emitted light due to high temperature.

(Measures for LED aging (1))
The LED control unit 406a increases the light emission amount of the LED according to the decrease of the light emission amount due to the aging deterioration of the LED on the transmission side in the non-contact communication unit 6a. Similarly, the LED control unit 406b increases the light emission amount of the LED according to the decrease in the light emission amount due to the aging deterioration of the LED on the transmission side in the non-contact communication unit 6b.

  Specifically, a table showing the relationship between the LED usage time and the amount of emitted light is prepared, the amount of emitted light is estimated from the current LED usage time from this table, and the estimated amount of emitted light is appropriate for communication by the LED. If the amount of light emitted is less than the threshold value (threshold), control is performed to increase the voltage applied to the LED so as to increase the amount of light emitted by the LED.

(Measures against LED aging (2))
The LED control unit 406a sets the threshold value of the light emission amount of the LED for determining whether or not the non-contact communication by the non-contact communication unit 6a is appropriately performed by the communication state determination unit 11, and the light emission amount due to the aging of the LED. Change according to decrease. Similarly, the LED control unit 406b sets the threshold of the light emission amount of the LED for determining whether or not the non-contact communication by the non-contact communication unit 6b is appropriately performed by the communication state determination unit 41, and the aging deterioration of the LED. It changes according to the decrease of the emitted light quantity by. That is, the LED control units 406a and 406b also function as a threshold value changing unit that changes the threshold value of the light emission amount of the LED.

(Temperature characteristics (light quantity decrease due to high temperature) compensation measures (1))
First, a temperature and LED light quantity control table is prepared. This table shows how much the light emission amount of the LED is increased for each temperature in order to keep the light emission amount of the LED constant because the light emission amount of the LED decreases at a high temperature.

  Therefore, the LED control unit 406a refers to the temperature and LED light amount control table from the temperature measured by the temperature sensor 405a of the lid 402, and controls the light emission amount of the LED according to the measured temperature. Similarly, the LED control unit 406b refers to the temperature and LED light amount control table from the temperature measured by the temperature sensor 405b of the rice cooker body 403, and controls the light emission amount of the LED according to the measured temperature.

(Temperature characteristics (light quantity decrease due to high temperature) compensation measures (2))
The LED control unit 406a sets the threshold value of the light emission amount of the LED for determining whether or not the non-contact communication by the non-contact communication unit 6a is appropriately performed by the communication state determination unit 11, and the light emission light amount due to the high temperature of the LED. Change according to decrease. Similarly, the LED control unit 406b determines the threshold value of the light emission amount of the LED for determining whether or not the non-contact communication by the non-contact communication unit 6b is appropriately performed by the communication state determination unit 41, depending on the high temperature of the LED. Change according to the decrease in the amount of emitted light. That is, the LED control units 406a and 406b also function as a threshold value changing unit that changes the threshold value of the light emission amount of the LED.

(effect)
According to the rice cooker 401 of the said structure, the influence by the reduction | decrease in the emitted light amount by aged deterioration of LED and a temperature rise can be decreased. Thereby, the rice cooker 401 can always perform non-contact communication appropriately, even if the light emission quantity by LED aged deterioration and the temperature rise reduces.

  In addition, in said example, although the case where it was LED as a light emitting element was demonstrated, it is not limited to this.

  In addition, in the said Embodiment 1-4, although the rice cooker was demonstrated as an example of the cooker of this invention, it is not limited to this, Other heating cookers may be sufficient and cooking which does not heat It may be a vessel, for example a warmer.

  The control block (especially lid displacement detection circuit) of the rice cooker 1 may be realized by a logic circuit (hardware) formed in an integrated circuit (IC chip) or the like, or software using a CPU (Central Processing Unit). It may be realized by.

  In the latter case, the rice cooker 1 includes a CPU that executes instructions of a program that is software that realizes each function, a ROM (Read Only Memory) in which the program and various data are recorded so as to be readable by a computer (or CPU), or A storage device (these are referred to as “recording media”), a RAM (Random Access Memory) that expands the program, and the like are provided. And the objective of this invention is achieved when a computer (or CPU) reads the said program from the said recording medium and runs it. As the recording medium, a “non-temporary tangible medium” such as a tape, a disk, 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 (such as a communication network or a broadcast wave) that can transmit the program. The present invention can also be realized in the form of a data signal embedded in a carrier wave in which the program is embodied by electronic transmission.
