FIG. 5 is an operation flowchart of the humidity sensor with a battery in the storage according to the first embodiment. FIG. 6 is a control flowchart of the storage room control of the storage according to the first embodiment.

  In the refrigerator shown in FIG. 1, a first refrigerator compartment 12, a second refrigerator compartment 13, and a freezer compartment 14 each functioning as a storage compartment are formed in a refrigerator body 11 formed of a heat insulating casing. The first refrigerator compartment 12 has a first refrigerator compartment door 15, the second refrigerator compartment 13 has a second refrigerator compartment door 16, and the freezer compartment 14 has a freezer compartment door 17, which is stored by closing the door. It can be sealed so that cool air in the room does not touch the outside of the storage room.

  In the first refrigerator compartment 12, there are a plurality of partition shelves 19 in which an antenna induced voltage operating temperature sensor 18 which is a wireless sensor having a temperature detecting function is installed in the center, and a demand side which is a wireless sensor having a pressure detecting function. A pressure sensor 20 with a non-contact power source and a humidity sensor 21 with a battery as a wireless sensor having a humidity detection function are provided, and an antenna 22 for communicating with the wireless sensor and a supply-side non-contact power source 23 are embedded in the wall surface. ing.

  The antenna induced voltage operating temperature sensor 18 generates an induced voltage by changing the magnetic flux around the antenna of the antenna induced voltage operating temperature sensor 18 from the radio wave transmitted from the antenna 22, and uses the induced voltage as an operating power source. In response to transmission of radio waves from the antenna 22, the antenna induced voltage operating temperature sensor 18 acquires temperature information and performs a passive operation of transmitting information wirelessly.

  The pressure sensor 20 with a demand-side non-contact power source is supplied with power from the supply-side non-contact power source 23, determines whether pressure is applied to the surface of the pressure sensor 20 with a demand-side non-contact power source, and actively transmits pressure information. can do. Further, since the supply-side non-contact power source 23 can supply a large amount of power, the output of the pressure sensor 20 with the demand-side non-contact power source can be increased.

  The battery-equipped humidity sensor 21 uses a battery as a power source, can measure changes in humidity, can actively transmit humidity information, and can also reduce power consumption.

  Further, the operating power source of the wireless sensor having the temperature detecting function may be a non-contact power source or a battery. Similarly, the pressure detection function and the humidity detection function may be any power source. Furthermore, one wireless sensor may have a plurality of functions.

  Since the wireless sensor transmits information wirelessly and the operating power is not supplied from the refrigerator main body 11 in a wired manner, it is easy even in places where wiring is difficult, such as the partition shelf 19 of the first refrigerator compartment 12. Installation is possible.

  The antenna 22 receives radio waves from the antenna induced voltage operating temperature sensor 18, the pressure sensor 20 with a demand-side non-contact power supply, and the wireless sensor 21 with a battery, and sends the received signal to the information reader 24. In addition, a signal from the information reader 24 outputs radio waves to the antenna induced voltage operating temperature sensor 18, the pressure sensor 20 with a non-contact power source on the demand side, and the wireless sensor of the humidity sensor 21 with battery.

  The information reading device 24 acquires a signal from the antenna 22 and sends the read signal to the control means 25 as information. Further, a signal is sent to the antenna 22 so as to output a radio wave in accordance with a command from the control means 25.

  The control means 25 uses the information from the information reading device 24 to control the cooler 26 and the cold air circulation means 27 and to control the storage room of the refrigerator main body 11. Further, a command is sent to the information reading device 24 so that the antenna outputs a signal requesting the wireless sensor to acquire the storage room state.

  Next, the operation of the antenna induced voltage operating temperature sensor 18 will be described with reference to FIG.

  First, in STEP 11, first, a radio wave is transmitted toward the antenna induced voltage operating temperature sensor 18, the surrounding magnetic flux changes at the antenna of the antenna induced voltage operating temperature sensor 18, an induced voltage is generated, and operation starts with the electromotive force. Then, the process proceeds to STEP12. On the other hand, if there is no change in the magnetic flux, the antenna induced voltage operating temperature sensor 18 does not start and the flow ends.

  In STEP 12, since the antenna induced voltage operating temperature sensor 18 is activated, the temperature of the temperature detecting unit of the antenna induced voltage operating temperature sensor 18 is acquired as a temperature state, and the process proceeds to STEP 13.

  In STEP 13, the temperature state acquired in STEP 12 is output as a radio wave signal, and the flow ends.

  By repeating the above STEP 11 to STEP 13, the antenna induced voltage operation temperature sensor 18 disposed in the first refrigerator compartment 12 can acquire the temperature of the first refrigerator compartment 12.

  Next, operation | movement of the pressure sensor 20 with a demand side non-contact power supply is demonstrated using FIG.

  First, in STEP 21, the operation is started by detecting a change in pressure by placing a stored item on the pressure sensor 20 with a demand-side non-contact power source or removing a stored item on the pressure sensor 20 with a demand-side non-contact power source. Then, transition to STEP22. On the other hand, if there is no change, the flow is terminated without starting.

  In STEP 22, it is determined whether the pressure change is an increase or a decrease. In the case of increase, the process proceeds to STEP23, and in the case of decrease, the process proceeds to STEP24.

  In STEP 23, since it is determined that the pressure has increased, the pressure information is increased, radio waves are output, and the flow is terminated.

  On the other hand, in STEP 24, since it is determined that the pressure has decreased, the pressure information is decreased, radio waves are output, and the flow ends.

  By repeating the flow shown in FIG. 4 described above, the pressure sensor 20 with a demand-side non-contact power source arranged in the first refrigerator compartment 12 can detect the presence or absence of stored items.

  Next, operation | movement of the humidity sensor 21 with a battery is demonstrated using FIG.

  First, in STEP 31, the humidity is detected by the sensor unit, and the process proceeds to STEP 32.

  In STEP32, if the detected humidity exceeds the threshold value compared with the threshold value provided in advance, the process proceeds to STEP33. If it is lower, the flow ends.

  In STEP33, since the humidity exceeds the threshold value, the humidity information is exceeded and the radio wave is output, and the flow is terminated.

  By repeating the flow shown in FIG. 5, the humidity sensor with a battery arranged in the first refrigerator compartment 12 can detect a change in humidity.

  Next, the operation of the storage room control will be described with reference to FIG.

  First, in STEP 401, it is determined whether or not the antenna 22 has received a radio wave. The radio wave received by the antenna 22 is output from the antenna induced voltage operating temperature sensor 18, the pressure sensor 20 with a demand-side non-contact power supply, and the humidity sensor 21 with a battery. When the antenna 22 receives radio waves, the process proceeds to STEP 402 in order to process the received radio waves. If no radio wave is received, the process proceeds to STEP 412. Now, assuming that the antenna 22 has received radio waves, the process proceeds to STEP 402.

  In the next STEP 402, since the antenna 22 has received the radio wave, the received signal is sent to the information reading device 24 in order to convert the signal into information.

  In the next STEP 403, the information reading device 24 reads a signal transmitted from the antenna 22 as information. Then, the read information is sent to the control means 25, and the process proceeds to STEP 404.

  In the next STEP 404, the control means 25 determines whether the information sent from the information reading device 24 is temperature information. If it is temperature information, the process proceeds to STEP 405. If it is other than temperature information, the process proceeds to STEP407. Here, it is assumed here that the information sent from the information reading device 24 is temperature information.

  In the next STEP 405, since the control means 25 has acquired the temperature information, the first refrigerator compartment is compared with the target temperature of the first refrigerator compartment 12 and the temperature of the first refrigerator compartment 12 obtained from the temperature information. If the temperature of 12 is higher than the target temperature of the first refrigerator compartment 12, the operation of the cooler and the cold air circulation means are controlled to lower the temperature of the first refrigerator compartment 12. On the contrary, if the temperature of the 1st refrigerator compartment 12 is lower than the target temperature of the 1st refrigerator compartment 12, a cooler stop and a cool air circulation means are controlled so that the temperature of the 1st refrigerator compartment 12 may be raised. And it changes to STEP406.

  In the next STEP 406, when the antenna 22 receives a plurality of signals in STEP 401, unprocessed information is generated. Therefore, it is determined whether or not there is unprocessed information. When there is unprocessed information, the process proceeds to STEP 404. Now, assuming that there is pressure information and humidity information as unprocessed information, the process proceeds to STEP 404.

  In STEP 404, since the next unprocessed information is pressure information, it becomes information other than temperature information, and the process proceeds to STEP 407.

  In the next STEP 407, the control means 25 determines whether the information sent from the information reader 24 is pressure information. If it is pressure information, the process proceeds to STEP 408. If it is not pressure information, the process proceeds to STEP 411. Since the information is pressure information here, the process proceeds to STEP 408.

  In the next STEP 408, it is determined whether or not the pressure information is increased. If the pressure information increases, the process proceeds to STEP 409. If not increased, the process proceeds to STEP410. Here, it is assumed that the pressure information is increasing, and the process proceeds to STEP 409.

  In the next STEP 409, since it is determined that the pressure information is increased, it is determined that the stored item is arranged in the first refrigerator compartment 12, and the storage process is performed assuming that the stored item is stored. Then, the process proceeds to STEP 406.

  If the pressure information is not increased in STEP 408, the process proceeds to STEP 410. However, in STEP 410, the pressure information is not increased, and therefore the pressure information is decreased. It determines with the stored material having been removed by the 1st refrigerator compartment 12, and performs the delivery process on the assumption that the stored material was delivered. And it changes to STEP406. Inventory management such as entry / exit management can be performed for the processing of STEP 409 and STEP 410.

  The process transits again to STEP 406. Since it is assumed that there is humidity information as unprocessed information this time, the process transits to STEP 404 again. Since the unprocessed information is humidity information, the process transits from STEP 404 to STEP 408 and from STEP 408 to STEP 411.

  The next STEP 411 is information other than temperature information and pressure information, and this time is humidity information. Since the humidity sensor 21 with a battery is installed 30 cm from the first refrigerator compartment door 15 when the first refrigerator compartment 12 is sealed, the humidity of the first refrigerator compartment door 15 is influenced by outside air when the door is opened. Rises. That is, by setting the threshold value to a value higher than the humidity in the sealed state, the humidity information exceeding the threshold means that the first refrigerator compartment 12 is not sealed by the first refrigerator compartment door 15. Thereby, the clearance gap between the 1st refrigerator compartment 12 and the 1st refrigerator compartment door 15 which cannot be detected with a switch etc. is detectable. The control means 25 receives a threshold value exceeding the humidity information, determines that the gap is detected, and performs door gap detection processing. As processing, control of the cooler 26 and the cold air circulation means 27, notification to the outside, and the like are performed. Then, the process proceeds to STEP 406.

  Since there is no unprocessed information in this STEP 406, the flow ends.

  Further, in this description, it is assumed that the antenna 22 has received a radio wave in STEP 401, but hereinafter, a case in which no data is received in STEP 401 will be described. If not received, the process proceeds to STEP 412. STEP 412 and subsequent steps are a flow for acquiring temperature data.

  In the next STEP 412, it is determined whether or not a predetermined time has elapsed in order to acquire temperature data at predetermined time intervals. If the predetermined time has elapsed, the process proceeds to STEP 413. If the predetermined time has not elapsed, the flow ends. Here, assuming that a predetermined time has elapsed, the process proceeds to STEP 413.

  In the next STEP 413, in order to acquire temperature data from the antenna induced voltage operation temperature sensor 18, an information acquisition command for requesting acquisition of temperature data is sent from the control means 25 to the information reader 24, and the process proceeds to STEP 414.

  In STEP 414, the information reading device 24 that has received the information acquisition command sends to the antenna 22 a signal that outputs a radio wave that requests the antenna induced voltage operation temperature sensor 18 to output temperature data, and the process proceeds to STEP 415. .

  In STEP 415, the antenna 22 that has received the signal from the information reading device 24 outputs a radio wave requesting the antenna induced voltage operation temperature sensor 18 to output temperature data, and the flow ends.

  By repeating the flow shown in FIG. 6 above, the control means 25 can grasp the storage room state of the first refrigerator compartment 12 and perform appropriate storage room control.

An air volume control device 31 and a humidity sensor 21 with a battery as a humidity wireless sensor are provided, and an antenna 22 for communicating with the wireless sensor and a supply-side non-contact power source 23 are embedded in the wall surface.

  The antenna induced voltage operating temperature sensor 18 generates an induced voltage by changing the magnetic flux around the antenna of the antenna induced voltage operating temperature sensor 18 from the radio wave transmitted from the antenna 22, and uses the induced voltage as an operating power source. In response to transmission of radio waves from the antenna 22, the antenna induced voltage operating temperature sensor 18 acquires temperature information and performs a passive operation of transmitting information wirelessly.

In addition, an induced voltage is generated by changing the magnetic flux around the antenna of the wireless tag, and the induced voltage is used as an operating power source. In response to the transmission of radio waves from the antenna 22, the wireless tag 30 acquires control information and performs a passive operation of transmitting information wirelessly. The opening / closing operation of the air volume control device 31 is determined based on the control information.

  The battery-equipped humidity sensor 21 uses a battery as a power source, can measure changes in humidity, can actively transmit humidity information, and can also reduce power consumption.

  Further, the operating power source of the wireless sensor having the temperature detecting function may be a non-contact power source or a battery. Similarly, the pressure detection function and the humidity detection function may be any power source. Furthermore, one wireless sensor may have a plurality of functions. Since the wireless sensor transmits information wirelessly and the operating power is not supplied from the refrigerator main body 11 in a wired manner, it is easy even in places where wiring is difficult, such as the partition shelf 19 of the first refrigerator compartment 12. Installation is possible.

  The antenna 22 receives radio waves from the antenna induced voltage operating temperature sensor 18, the air volume control device 31 with a demand-side non-contact power supply, and the wireless sensor of the humidity sensor 21 with battery, and sends the received signal to the information reading device 24. In addition, a radio wave is output to the wireless sensor of the antenna induced voltage operating temperature sensor 18, the air flow control device 31 with a demand-side non-contact power supply, and the humidity sensor 21 with a battery by a signal from the information reader 24.

  The information reading device 24 acquires a signal from the antenna 22 and sends the read signal to the control means 25 as information. Further, a signal is sent to the antenna 22 so as to output a radio wave in accordance with a command from the control means 25.

  The control means 25 uses the information from the information reading device 24 to control the cooler 26 and the cold air circulation means 27, and in addition to the storage room control of the refrigerator main body 11, control information for controlling the air volume of the storage room. The control information is calculated and sent to the air volume control device 31 via the wireless tag 30. As a result, the air volume control device changes and fixes the louver to an appropriate angle.

  Next, the operation of the antenna induced voltage operating temperature sensor 18 will be described with reference to FIG.

Then, the process proceeds to STEP52. On the other hand, if there is no change in the magnetic flux, the antenna induced voltage operating temperature sensor 18 does not start and the flow ends.

  In STEP 52, since the antenna induced voltage operating temperature sensor 18 is activated, the temperature of the temperature detection unit of the antenna induced voltage operating temperature sensor 18 is acquired as a temperature state, and the process proceeds to STEP 53.

  In STEP 53, the temperature state acquired in STEP 52 is output as a radio wave signal, and the flow ends.

  By repeating the above STEP 51 to STEP 53, the antenna induced voltage operation temperature sensor 18 arranged in the first refrigerator compartment 12 can acquire the temperature of the first refrigerator compartment 12.

  Next, operation | movement of the air volume control apparatus 31 with the demand side non-contact power supply 29 is demonstrated using FIG.

  First, in STEP 61, an operation is started by a change in control information transmitted from the control means 25 to the wireless tag 30 via the antenna 22 and the information reading device 24 to the air volume control device 31 with the demand-side non-contact power supply 29. Transition to. On the other hand, if there is no change, the flow is terminated without starting.

  In STEP 62, it is determined whether the value of the control information is increased or decreased. If it is increased, the process proceeds to STEP 63, and if it is decreased, the process proceeds to STEP 64.

  In STEP 63, the louver opening / closing angle is opened larger than the current state, and the flow is terminated.

  On the other hand, in STEP 64, the louver opening / closing angle is closed to be smaller than the current state, and the flow is ended.

  By repeating the flow shown in FIG. 11, the air volume control device 31 with the demand-side non-contact power supply 29 arranged in the first refrigerator compartment 12 opens and closes the louver 28 based on the control information calculated by the control means 25. It will be.

  Next, operation | movement of the humidity sensor 21 with a battery is demonstrated using FIG.

  In STEP72, if the detected humidity exceeds the threshold value compared with the threshold value provided in advance, the process proceeds to STEP73. If it is lower, the flow ends.

  In STEP 73, since the humidity exceeds the threshold, the humidity information is set to exceed the threshold, a radio wave is output, and the flow ends.

  By repeating the flow shown in FIG. 12, the humidity sensor with a battery disposed in the first refrigerator compartment 12 can detect a change in humidity.

  Next, the operation of the storage room control will be described with reference to FIG.

  First, in STEP 801, it is determined whether the antenna 22 has received a radio wave.

When the antenna 22 receives a radio wave, the process proceeds to STEP 802 to process the received radio wave. If no radio wave is received, the process proceeds to STEP 812. Now, assuming that the antenna 22 has received a radio wave, the process proceeds to STEP 802.

  In the next STEP 802, since the antenna 22 receives the radio wave, the received signal is sent to the information reading device 24 in order to convert the signal into information.

  In the next STEP 803, the information reading device 24 reads a signal transmitted from the antenna 22 as information. Then, the read information is sent to the control means 25, and the process proceeds to STEP804.

  In the next STEP 804, the control means 25 determines whether the information sent from the information reading device 24 is temperature information. If it is temperature information, the process proceeds to STEP 805. If it is other than temperature information, the process proceeds to STEP 807. Here, it is assumed here that the information sent from the information reading device 24 is temperature information.

  In the next STEP 805, since the control means 25 has acquired the temperature information, the target temperature of the first refrigerator compartment 12 is compared with the temperature of the first refrigerator compartment 12 obtained from the temperature information, and the first refrigerator compartment is compared. If the temperature of 12 is higher than the target temperature of the first refrigerator compartment 12, the operation of the cooler and the cold air circulation means are controlled to lower the temperature of the first refrigerator compartment 12. On the contrary, if the temperature of the 1st refrigerator compartment 12 is lower than the target temperature of the 1st refrigerator compartment 12, a cooler stop and a cool air circulation means are controlled so that the temperature of the 1st refrigerator compartment 12 may be raised. And it changes to STEP806.

  In the next STEP 806, when the antenna 22 receives a plurality of signals in STEP 801, unprocessed information is generated. Therefore, it is determined whether there is any unprocessed information. When there is unprocessed information, the process proceeds to STEP 804. Now, assuming that there is pressure information and humidity information as unprocessed information, the process proceeds to STEP 804.

  In STEP 804, since the next unprocessed information is control information, the information becomes information other than the control information, and the process proceeds to STEP 809.

  In the next STEP 804, the control means 25 determines whether or not the information sent from the information reading device 24 is control information. If it is control information, the process proceeds to STEP 805. If it is not control information, the process ends.

  In the next STEP 806, if the control information increases, the louver opening is increased in STEP 807, and the process proceeds to STEP 806. If not increased, the process proceeds to STEP 808, the louver opening is reduced, and the process proceeds to STEP 806.

  In this description, it is assumed that the antenna 22 receives a radio wave in STEP 801. Hereinafter, a case where data is not received in STEP 801 will be described. If not received, the process proceeds to STEP812. Steps 812 and after are a flow for acquiring temperature data.

  In the next STEP 812, it is determined whether or not a predetermined time has elapsed in order to acquire temperature data at predetermined time intervals. If the predetermined time has elapsed, the process proceeds to STEP 813. If the predetermined time has not elapsed, the flow ends. Here, assuming that a predetermined time has elapsed, the process proceeds to STEP 813.

  In the next STEP813, in order to acquire temperature data from the antenna induced voltage operation temperature sensor 18, an information acquisition command for requesting acquisition of temperature data is sent from the control means 25 to the information reader 24, and the process proceeds to STEP814.

  In STEP 814, the information reading device 24 that has received the information acquisition command sends a signal to the antenna 22 that outputs a radio wave that requests the antenna induced voltage operation temperature sensor 18 to output temperature data, and the process proceeds to STEP 815. .

  In STEP 815, the antenna 22 that has received the signal from the information reading device 24 outputs a radio wave requesting the antenna induced voltage operation temperature sensor 18 to output temperature data, and the flow ends.
