There has been a problem that it is not possible to stop the operation or that the radio devices existing around the microwave heating device cannot communicate with each other due to microwave noise.

Further, there is another problem that a communication error occurs continuously until the communication frequency moves to a frequency band in which communication can be performed. For example, in the case of FIG. 8, a communication error occurs m times.

An I13 and an antenna 14 are provided, and data transmitted from a microprocessor 15 that controls the remote controller 3 is output as a wireless signal through the wireless communication LSI 13 and the antenna 14. The wireless signal received through the antenna 14 is received as data by the microprocessor 15 through the wireless communication LSI 13. Control of various communication operations of the microwave heating device 1, the air conditioner 2, and the remote controller 3 is performed by the microprocessors 9, 12, and 15, respectively.

Next, the operation will be described with reference to FIG. First, upon receiving the signal of “heating start instruction S1” transmitted from the remote controller 3, the microwave heating apparatus 1 transmits the signal of “heating start S2” to the radio 4 of the microwave heating apparatus 1.
All the radios 5 and 6 except for are broadcasted at once, and the heating operation is started immediately thereafter. (Hereinafter, heating refers to heating by microwaves). When 5 seconds elapse after the start of heating, the heating is stopped for 5 seconds. Thereafter, the microwave heating device 1 repeats heating and pausing every 5 seconds.

On the other hand, the radios 5 and 6 and the radio 4 which have received the signal of "heating start S2" reset their own communication timers, and for 5 seconds, the micro-wave generated by the heating operation of the microwave heating apparatus 1 is activated. The communication operation is stopped because the communication performance is deteriorated due to the noise of the waves or the communication cannot be performed at all. After 5 seconds elapse and the heating operation is stopped, each of the radios 4, 5, and 6 starts data transmission and reception after a random time interval (about several ms) for each radio, and After the elapse, the heating operation is restarted, so that all the wireless devices 4, 5, and 6 stop the communication operation. Thereafter, data transmission and reception and stop are repeated in response to the stop of the heating operation and the restart of the heating operation.

However, a switch provided on the microwave heating apparatus 1 itself, for example, a cooking start switch (not shown) Similarly, when operated by operating, the signal of "heating start S2" is transmitted to all the radios 5, 6 except the radio 4 of the microwave heating apparatus 1, and the radios 5, 6 which have received the signal are transmitted. And the radio 4
It goes without saying that the timer may be reset and the communication may be performed during the heating stop time.

Embodiment 2 FIG. FIG. 4 is a diagram showing an operation of the wireless communication system according to the second embodiment of the present invention. The configuration diagram of the wireless communication system and the block diagram of the wireless communication unit of each device are the same as those in FIGS.

In the first embodiment, the notification of "heating start S2" from the microwave heating device 1 to all the wireless devices 5, 6 excluding the wireless device 4 of the microwave heating device 1 is only a signal of the heating start. The subsequent heating and the heating pause are performed based on a predetermined time, and the wireless devices 5 and 6 and the wireless device 4 that have received the notification of the “heating start S2” perform the above-described predetermined heating, Although the communication operation time and the communication stop time are set based on the heating pause time, in the second embodiment, the “heating operation time” and the “heating stop time” are set when the signal of “heating start S2” is transmitted. And send it with
All the wireless devices that have received this perform communication in accordance with the stop time of the microwave heating device 1 based on this information, as in the first embodiment.

FIG. 4 shows the state when the signal of "heating start S2" is transmitted.
This shows that information is transmitted for a heating operation time of 4 seconds and a heating pause time of 3 seconds, and that all the wireless devices communicate with the stop time of the microwave heating device 1 for 3 seconds. Therefore, the microwave heating device 1 can flexibly change the interval between the heating operation time and the stop time according to the type and method of cooking.

Embodiment 3 FIG. 5 is a diagram showing an operation of the wireless communication system according to the third embodiment of the present invention. The configuration diagram of the wireless communication system and the block diagram of the wireless communication unit of each device are the same as those in FIGS.

In the second embodiment, once heating is started, a predetermined heating operation time and a predetermined stop time are operated, and these times are not changed on the way. In each case, at the end of the stop time, the next heating operation time and the stop time are determined, and the “next heating operation time length S3” is defined as the “all next wireless operation except the wireless device 4 of the microwave heating device 1 from the microwave heating device 1”. To the devices 5 and 6. Each of the radios 5 and 6 and the radio 4 receiving the signal of the “next heating operation time length S3” resets their own communication timer, and performs the communication operation while the microwave heating device 1 is heating. Is stopped, and each radio 4,
Data transmission and reception 5 and 6 are performed after a random time interval (about several ms) is provided for each wireless device.

FIG. 5 shows a state in which the signal of "heating start S2" is transmitted.

"3" indicates that information of a heating operation time of 4 seconds and information of a heating pause time of 3 seconds is transmitted, and thereafter, information of a heating operation time and a pause time is transmitted at the end of each heating suspension time. . Therefore, it is possible to make the operation time and the stop time variable length, and in the microwave heating device 1,
A more flexible heating method becomes possible.

Embodiment 4 In the first to third embodiments, the case where heating is completely stopped during the heating stop time has been described. In the fourth embodiment, heating is performed at a microwave output level at which all wireless devices can communicate. explain. FIG. 6 is a state transition diagram of the operation of the wireless communication system according to the fourth embodiment of the present invention. The configuration diagram of the wireless communication system and the block diagram of the wireless communication unit of each device are shown in FIG.
It is the same as FIG.

First, in Embodiments 1 to 3, the heating operation time and the heating stop time alternately occur, and all the radio devices 5 and 6 other than the microwave heating device 1 that has received the data of "heating start S2" Then, data is transmitted for each heating stop time, and if there is no data to be transmitted, "communication performance verification" data is transmitted. On the other hand, the microwave heating apparatus 1 always receives the data of all the wireless devices, and manages the number of received data, that is, the number of all the existing wireless devices.

Therefore, in the fourth embodiment, the microwave heating apparatus 1 completely stops heating during the first heating stop time, and counts the number of data of all the wireless devices. At this time,
When the data number of all the radios is 0, there is no radio in the vicinity, so that it is not necessary to stop heating thereafter, and the microwave heating device 1 performs the heating operation set by the timer of the microwave heating device 1. Heating is performed at maximum output in time.

On the other hand, the number of data of all the radios is counted, and when the existence of the radio is confirmed, the number of radios is stored. Then, in the second heating stop time, the microwave heating device performs the heating operation with low power without completely stopping the heating. For example, the maximum output of a normal heating operation is 400
If it is W, heating is performed at an output of 100 W. Further, also in the low output heating time, similarly to the above, the microwave heating apparatus 1 receives the data of all the radios, and after the start of the heating operation, reduces the number of received data by the number of data of all the radios received for the first time. Compare with As a result, if the number of received data is reduced, a wireless device that cannot perform data transmission / reception has occurred due to the low-power heating operation, so that the output is returned to the immediately preceding output and the heating operation is performed. On the other hand, when the number of received data does not decrease, in the third heating stop time, the heating operation is performed at a lower power by increasing the power than in the second heating stop time. Hereinafter, similarly, the heating operation and the stop or the weak operation are repeated.

In the heating operation, if the heating operation is properly performed in the weak operation without repeating the heating operation and the stop or the weak operation, the heating operation is performed in the weak operation. The same instruction as “stop heating” is sent to all radios, but an instruction to “stop timer” is sent so that all radios can transmit and receive data at any time.

Next, a specific description will be given with reference to FIG. First, the microwave heating apparatus 1 obtains an output necessary for heating the food put in the heating chamber, and sets a heating of J6, for example, 400 W. Then, when heating is started, “Heating start S
The data of "2" is transmitted to all the wireless devices 5 and 6 except the wireless device 4 of the microwave heating device 1, and transition to the 400W heating operation of J6 is performed (T1), and the heating operation is performed for a fixed time, for example, 5 seconds. Then, after the heating operation is completed, a transition is made to stop heating of J1 (T2), and data from all the radios 4 and 5 are waited. The data transmitted from each of the radios 4 and 5 is received. Thereby, the number of all the wireless devices existing in the vicinity can be confirmed. In this case, the number is two.

Thereafter, after a predetermined time, for example, 5 seconds, J
The process transitions to the 400W heating operation 6 (T3), and the heating operation is performed for 5 seconds. After the heating operation is completed, J
The operation transits to 100W heating operation of No. 2 (T4), and the number of data from all wireless devices is confirmed. Therefore, if the number of radio devices is smaller than the number of radio devices previously confirmed, a radio device that cannot perform data transmission and reception due to weak operation has occurred, and thereafter, the microwave heating apparatus 1 performs “400 W heating” and “heating”. The heating operation is performed by repeating “stop”.

On the other hand, if the number of radios is the same as the number confirmed at the time of stopping the heating of J1, the 100W heating operation of J2 is reduced to 5 times.
After that, the operation transits to 400W heating operation of J6 (T5).
The operation transits to the 00W heating operation (T6), and the number of data from all the radios is confirmed in the 200W heating operation. Here, J1
When the number of wireless devices confirmed at the time of the stop of the heating is reduced, the operation of the microwave heating apparatus 1 is thereafter changed to “400 W
The heating operation is performed by repeating “heating” and “100 W heating”.

On the other hand, if the number of radios is the same as the number confirmed when the heating of J1 is stopped, the 200W heating operation of J3 is reduced by 5 times.
After that, the operation transits to 400W heating operation of J6 (T7).
The operation transits to the 00W heating operation (T8), and the number of data from all the wireless devices is confirmed in the 300W heating operation. Thereafter, the same operation is performed to determine the maximum output of the weak operation in which the microwave heating device 1 and all wireless devices can communicate. If it is confirmed that communication can be performed between the 400W heating operation of J5 and the 400W heating operation of J6, communication can be performed even during heating. Therefore, an instruction of “timer stop” is notified to all wireless devices, and communication is performed regardless of the timer. To do it.

Embodiment 5 In the first to third embodiments,
During the heating operation of the microwave heating apparatus 1, the communication between the wireless devices is stopped. In the fourth embodiment, the output level of the microwave is adjusted to enable communication between the wireless devices. Even during the heating operation time of the heating device 1, there is a possibility that wireless devices existing in an area (place) where electromagnetic noise radiated from the microwave heating device 1 is small among all wireless devices can communicate with each other. Therefore, the fifth embodiment
Then, all wireless devices intentionally perform communication during the heating time while knowing that the possibility of communication is low even when the microwave heating device 1 is in the heating operation time, and if the communication is not successful, In this case, communication is performed using the stop time of the microwave heating device 1.

FIG. 7 is a diagram showing an operation of the wireless communication system according to the fifth embodiment of the present invention. The configuration diagram of the wireless communication system and the block diagram of the wireless communication unit of each device are the same as those in FIGS. Although not shown, the ventilation fan is provided with a ventilation fan control microprocessor and a radio as in the air conditioner and the like, and the radio is provided with an antenna and a wireless communication LSI.

Next, the operation will be described with reference to FIG. First, during the heating operation of the microwave heating device 1, the remote controller 3 transmits a signal to the air conditioner 2 (S11), and the remote controller 3 receives a reception response from the air conditioner 2 (S12), so that communication was successful. Detect that Next, the remote control 3
Transmitted a signal to the ventilation fan, and the ventilation fan received (S13)
However, the remote controller 3 did not receive the reception response (S1
4) Thus, it is determined that the communication has failed. However, since the remote controller 3 is communicating during the heating operation of the microwave heating device 1, the communication to the ventilation fan is distinguished from the communication failure at the normal time, and the communication is performed again during the stop time of the microwave heating device 1. Do.

In the above description, the communication between the remote controller 3 and the ventilation fan has been described, but the one-to-one communication between the microwave heating device 1 and any one device (radio device) is similarly performed. As described above, the wireless devices that can communicate during the heating operation of the microwave heating apparatus 1 communicate during the heating operation as well as during the heating stop, so that the communication during the heating stop is such that the microwave heating apparatus 1 stops. The communication can be limited to communication between essential wireless devices, which can contribute to a reduction in traffic.
