Description

Food storage containers, food quality measurement systems, refrigerators and freezers

This disclosure relates to food storage containers, food quality measurement systems, refrigerators, and freezers.

Conventionally, there is known a technique of providing a sensor inside a container to monitor conditions that affect the quality of food inside the container (see, for example, Patent Document 1).
By the way, some foods can be stored for a certain period of time. On the other hand, when food comes into contact with oxygen, it begins to oxidize and its quality such as taste or flavor deteriorates. Therefore, when preserving food, it is preferable to prevent the food from coming into contact with oxygen so that the food can be preserved while preventing deterioration of the food. Therefore, as a method for preserving food, a method is known in which the food is placed in a container and the inside of the container is evacuated.

Japanese Patent Publication No. 2008-536774

When food is stored in a vacuum container, users such as food managers need to check the quality of the food during the storage period. However, the user has to open the vacuum container each time he wants to check the quality of the food. When the vacuum container is opened, the vacuum inside the container is no longer maintained and the food is exposed to oxygen. When a sensor for quality monitoring is provided in such a vacuum vessel, it is preferable that the battery for the sensor is small considering that the user will carry the vacuum vessel. , the battery may run out. As described above, there is a problem that the quality of food cannot be confirmed while maintaining the vacuum state over a long storage period.

The present disclosure was made to solve the above problems, and aims to provide a food storage container that presents information that allows the quality of food to be confirmed while maintaining a vacuum state.

A food storage container according to the present disclosure includes a lid and a container body, a vacuum container portion capable of storing food in a vacuum state, a power receiving portion capable of contactlessly receiving power from a power transmission device, and a power receiving portion receiving power. It is equipped with a sensor that measures the characteristics of the food stored in the vacuum container based on electric power, and a control unit that outputs quality information based on the characteristics measured by the sensor.

According to this disclosure, it is possible to present information that allows the quality of food to be confirmed while maintaining a vacuum state.

Embodiment 1.
FIG. 1 is a diagram for explaining an image of an example of a food quality measuring system 1 having a food storage container 10 according to Embodiment 1. FIG. FIG. 1 shows an image of a cross section of the food storage container 10. As shown in FIG.
FIG. 2 is a block diagram showing a configuration example of the food quality measurement system 1 provided with the food storage container 10 according to Embodiment 1. As shown in FIG.

A food quality measurement system 1 according to Embodiment 1 includes a food storage container 10 and a power transmission device 20 .
The food quality measurement system 1 can supply power to the food storage container 10 existing within the power supply range of the power transmission device 20 by wireless power supply without a wired connection.
The power transmission device 20 is provided on various members such as a shelf board, a kitchen table, a table top, or other structural members, and supplies electric power to the power receiving unit 111 provided in the food storage container 10 in a non-contact manner. (details will be described later).

The food storage container 10 includes a measurement control device 11 and a vacuum vessel section 12 , and food 3 is stored in the vacuum vessel section 12 . In Embodiment 1, the food 3 stored in the vacuum vessel part 12 is assumed to be food that can be stored for a certain period of time. More specifically, in Embodiment 1, the food 3 stored in the vacuum vessel part 12 is assumed to be food that can be stored in a state of being eaten for a certain period of time even if it is not consumed immediately. In FIG. 1, one apple is stored in the vacuum vessel section 12 as an example.
In addition, in Embodiment 1, the food storage container 10 is assumed to be portable, for example, for general household use.
The vacuum vessel section 12 includes a vessel body 121 , a lid 122 and a display section 123 .
The container body 121 accommodates the food 3.
The lid 122 covers the container body 121 and brings the vacuum container section 12 into a vacuum state. The lid 122 is provided with an exhaust port 1221 with a check valve for removing the air in the vacuum vessel section 12 . By removing the air from the exhaust port 1221 with a check valve, the inside of the vacuum vessel section 12 is decompressed.
The display unit 123 is provided on the side surface of the container body 121 of the vacuum container unit 12, for example, as shown in FIG. In Embodiment 1, the display unit 123 is assumed to be, for example, a liquid crystal display. The display unit 123 may be composed of, for example, a 7-segment display. A user can check the display surface of the display unit 123 from the outside of the vacuum container unit 12 .
The display unit 123 is connected to a power receiving unit 111 (details of which will be described later) of the food storage container 10 via a terminal (not shown), and is driven by power received from the power receiving unit 111 via the terminal. In addition, the display unit 123 is connected to a control unit 113 (details will be described later) of the food storage container 10 via a terminal (not shown). Information (hereinafter referred to as "quality information") regarding values indicating the characteristics of the food 3 (hereinafter referred to as "characteristic values") is displayed.
The user confirms the quality of the food 3 stored in the food storage container 10 by confirming the quality information displayed by the display unit 123 . The quality of the food 3 is represented by its characteristic values, for example.
In Embodiment 1, the quality information of the food 3 is also simply referred to as "quality information".

The measurement control device 11 is provided inside the vacuum vessel section 12 and includes a power receiving section 111 , a sensor 112 and a control section 113 . The power receiving unit 111, the sensor 112, and the control unit 113 are connected by terminals (not shown).
The power receiving unit 111 receives power in a contactless manner from the power transmission device 20 provided outside the food storage container 10 . Power receiving unit 111 outputs power received from power transmitting device 20 to sensor 112 and control unit 113 .

Here, FIG. 3 is a diagram for explaining detailed configurations of power reception unit 111 and power transmission device 20 and wireless power supply according to the first embodiment.
Note that in Embodiment 1, an appropriate method may be adopted as the wireless power feeding method. For example, the wireless power supply system employs an electromagnetic induction system, a magnetic field coupling system, an electric field coupling system, or a microwave system. Wireless power supply by electromagnetic induction method, wireless power supply by magnetic field coupling method, wireless power supply by electric field coupling method, and wireless power supply by microwave method are known technologies, so detailed description is omitted here. . Regarding the wireless power supply system, the electromagnetic induction system, the magnetic field coupling system, or the electric field coupling system is superior to the microwave system from the viewpoint of the efficiency of wireless power supply.
In Embodiment 1, as an example, it is assumed that the electromagnetic induction method is adopted as the wireless power feeding method. In the electromagnetic induction system, the magnetic flux radiated from the power transmission coil interlinks with the power reception coil to generate an electromotive force, and power can be supplied to the power reception side. If there is a receiving coil inside the transmitting coil, power can be supplied to the receiving side. Therefore, if the size of the power transmitting coil is increased, there is no need to require high accuracy in aligning the power receiving side coil. In this way, the electromagnetic dielectric system has the advantage of being resistant to misalignment on the power receiving side.

As shown in FIG. 3 , the power transmission device 20 includes an activation section 21 , a DC-RF inverter 22 and a power transmission antenna 23 .
The activation unit 21 receives power supplied from, for example, a commercial power source. The starting unit 21 converts commercial power, which is AC power, into DC power, and outputs the converted DC power to the DC-RF inverter 22 .
The DC-RF inverter 22 converts the DC power output from the starter 21 into high frequency power.
The DC-RF inverter 22 supplies the converted high-frequency power to the power transmission antenna 23 .
The power transmission antenna 23 transmits high frequency power supplied from the DC-RF inverter 22 to the power reception unit 111 .

Further, as shown in FIG. 3, the power receiving unit 111 includes a power receiving antenna 1111, a rectifying unit 1112, and a DC-DC converter 1113.
The power receiving antenna 1111 receives power transmitted from the power transmitting antenna 23 of the power transmitting device 20 .
Power receiving antenna 1111 outputs the received power to rectifying section 1112 .
Rectifying section 1112 converts an RF (Radio Frequency) signal of power received by power receiving antenna 1111 into a DC voltage.
In wireless power supply, high-frequency electromagnetic waves are used to supply and receive power. In contrast, sensor 112 is driven by DC power. Therefore, in the power receiving unit 111, the rectifying unit 1112 converts the voltage into a DC voltage. A DC voltage obtained by converting the RF signal by the rectifying unit 1112 is referred to as a “first DC (Direct Current)”.
The rectifying section 1112 outputs the DC voltage after conversion, that is, the first DC to the DC-DC converter 1113 .
DC-DC converter 1113 converts the first DC output from rectifying section 1112 into a DC voltage necessary for driving sensor 112 . A DC voltage obtained by converting the first DC by the DC-DC converter 1113 is called a “second DC”.
DC-DC converter 1113 outputs the DC voltage after conversion, that is, the second DC to sensor 112 and control unit 113 . It should be noted that FIG. 3 omits illustration of the control unit 113 for simplicity of explanation.

Returning to the description of FIGS.
The sensor 112 is driven by the power output from the power receiving section 111 , in other words, the second DC, and measures the characteristics of the food 3 inside the vacuum vessel section 12 . More specifically, the sensor 112 measures characteristic values of the food 3 inside the vacuum vessel portion 12 .
Specifically, the sensor 112 has a sensor main body 1121 and measurement terminals 1122 , and the sensor main body 1121 measures characteristic values of the food 3 via the measurement terminals 1122 . The sensor body 1121 and the measurement terminal 1122 need not be integrated. 2, illustration of the sensor main body 1121 and the measurement terminal 1122 is omitted.
The measurement terminal 1122 may be provided so as to partially cover the bottom surface portion 12a of the container body 121 of the vacuum container portion 12, as shown in FIG. Note that this is merely an example, and the measurement terminal 1122 may be provided so as to cover the entire bottom surface portion 12 a of the container body 121 in the vacuum container portion 12 . It is sufficient that the measuring terminals 1122 come into contact with the food 3 .

In Embodiment 1, the sensor 112 measures the sugar content of the food 3 as a characteristic value of the food 3, for example. Moreover, the sensor 112 measures, for example, the moisture content or moisture content of the food 3 as a characteristic value of the food 3 . Moreover, the sensor 112 measures the salt content contained in the food 3 as a characteristic value of the food 3, for example. Further, the sensor 112 measures the hydrogen ion concentration (pH) of the food 3 as a characteristic value of the food 3, for example.
The sensor 112 outputs the measurement results of the characteristic values of the food 3 to the control section 113 .

The control unit 113 is driven by the power output from the power receiving unit 111 , in other words, the second DC, and outputs quality information based on the characteristics measured by the sensor 112 to the display unit 123 .
The food storage container 10 includes a display unit 123 or a communication unit (not shown) that performs wired or wireless communication with an external device or the like of the food storage container 10 . The control unit 113 outputs quality information via the communication unit. For example, the control unit 113 converts the data format of the quality information, and then outputs the quality information to the display unit 123 . That is, the control unit 113 causes the display unit 123 to display quality information based on the characteristics measured by the sensor 112 .
The control unit 113 causes the display unit 123 to display, for example, the characteristic value of the food 3 measured by the sensor 112 as quality information.
The functions of the control unit 113 are implemented by, for example, a processing circuit (not shown). That is, the food storage container 10 includes a processing circuit for controlling output of quality information of the food 3 based on the measurement of the food 3 measured by the sensor 112 . The processing circuit may be dedicated hardware or may be a CPU (Central Processing Unit, not shown) that executes a program stored in a memory (not shown).
If the processing circuit is dedicated hardware, the processing circuit may be, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array). ), or a combination thereof.
When the processing circuit is a CPU, the functions of the control unit 113 are implemented by software, firmware, or a combination of software and firmware.

FIG. 4 is a diagram showing an image of a screen example of display unit 123 on which quality information is displayed by control unit 113 in the first embodiment.
For example, as shown in FIG. 4, the control unit 113 causes the display unit 123 to display the measured characteristic value of the food 3 and information indicating the characteristic of the food 3 represented by the characteristic value in association with each other. The quality information includes the measured characteristic value of the food 3 and information indicating the characteristic of the food 3 represented by the characteristic value. The quality information may further include information about the date and time when the characteristic value was measured.
Note that the screen example shown in FIG. 4 is merely an example. The display unit 123 may display the quality information with illustrations, graphs, or icons, for example.
FIG. 4 shows a display example in which the characteristic of the food 3 measured by the sensor 112 is the sugar content, and the sugar content is displayed in percent, but this is only an example. For example, if the property of the food 3 measured by the sensor 112 is the water content, the display unit 123 displays information about the property value of the water content. Further, for example, if the characteristic of the food 3 measured by the sensor 112 is pH, the display unit 123 displays information regarding the characteristic value of pH.

As shown in FIG. 1, in the food storage container 10, among the components of the measurement control device 11, the power receiving unit 111, the sensor 112, and the control unit 113 are integrated into a module, and the container body in the vacuum container unit 12 121 is provided inside the bottom portion 12a. That is, the power receiving section 111 , the sensor 112 and the control section 113 are integrated into a module and embedded in the bottom surface portion 12 a of the container body 121 in the vacuum container portion 12 .
Measurement terminal 1122 is not modularized with power receiving unit 111 , sensor 112 , and control unit 113 . The sensor 112 can accurately measure the characteristic values of the food 3 by contacting the measurement terminal 1122 with the food 3 . Since the measuring terminal 1122 needs to be in contact with the food 3, it should be placed on the surface of the bottom surface 12a of the container main body 121 of the vacuum container 12 so as not to be embedded in the bottom surface 12a of the container main body 121 of the vacuum container 12, for example. provided in
That is, in the sensor 112 , the sensor main body 1121 is provided inside the bottom surface portion 12 a of the container main body 121 in the vacuum container portion 12 , and the measuring terminals 1122 are provided on the bottom surface portion 12 a of the container main body 121 in the vacuum container portion 12 and the food 3 . It is provided in the position which touches.
It is sufficient that at least the portion of the measuring terminal 1122 that senses the characteristics of the food 3 is in contact with the food 3 . That is, at least the portion of the measuring terminal 1122 that senses the characteristics of the food 3 should be in direct contact with the outside air inside the vacuum container portion 12 , and the other portion is the container body 121 in the vacuum container portion 12 . may be embedded inside the bottom surface portion 12a.

Also, as shown in FIG. 1, the power receiving unit 111 and the sensor 112 are provided at positions in contact with each other on the bottom surface portion 12a of the container body 121 in the vacuum container unit 12, and are connected by terminals.

As described above, in the food storage container 10 , the sensor 112 provided inside the vacuum container portion 12 measures the characteristic values of the food 3 inside the vacuum container portion 12 . The quality information is displayed on the display unit 123 outside the vacuum container unit 12 by the control unit 113 . That is, the food storage container 10 outputs the quality information to the outside of the food storage container 10 while maintaining the vacuum state of the vacuum container portion 12 .
Therefore, the user does not need to open the lid 122 of the vacuum vessel portion 12 each time to check the quality of the food 3 inside the vacuum vessel portion 12 . The user can check the quality of the food 3 while maintaining the vacuum state of the vacuum container part 12 . In addition, the food storage container 10 maintains the vacuum state of the vacuum container portion 12 to prevent the food 3 from coming into contact with oxygen. As a result, the food storage container 10 can prevent the quality of the food 3 from deteriorating.

In the food quality measurement system 1, the food storage container 10 includes a power receiving unit 111 that receives power from the power transmitting device 20 in a contactless manner, and the power received by the power receiving unit 111 is used to drive the sensor 112.
Since the food storage container 10 operates by wireless power supply, a large-capacity battery for driving the sensor 112 can be eliminated. Therefore, the food storage container 10 prevents a situation in which the battery of the sensor 112 runs out while the food 3 is being stored and the sensor 112 stops working. Note that, for example, a battery with a small capacity for temporarily storing the characteristic values measured by the sensor 112 may be provided in the food storage container 10 .
Moreover, the food storage container 10 does not require a power cord for supplying power to the sensor 112 . Therefore, the user can check the quality of the food 3 without running out of battery of the sensor, for example, even in a place where there is no outlet nearby. Also, the user who uses the food storage container 10 does not need to plug the power cord into an outlet each time the food storage container 10 is used. Moreover, the power cord does not become an obstacle for the user.

Further, in the food storage container 10 , the power receiving portion 111 , the sensor 112 and the control portion 113 are provided inside the bottom portion 12 a of the container body 121 in the vacuum container portion 12 . Therefore, the user can easily operate the vacuum container unit 12 compared to the case where the power receiving unit 111, the sensor 112, and the control unit 113 are installed in the same space as the food 3 is stored in the vacuum container unit 12, for example. can be washed.
Here, if the sensor 112 in the food storage container 10 is driven by a battery, and the battery is provided inside the bottom surface portion 12a of the container body 121 in the vacuum container portion 12, the user will not be able to replace the battery. it gets harder. However, food storage container 10 may not require a large capacity battery to power sensor 112, as described above. Therefore, even if the power receiving unit 111, the sensor 112, and the control unit 113 in the food storage container 10 are provided inside the bottom surface portion 12a of the container body 121 in the vacuum container portion 12, troublesome battery replacement does not occur.

Further, in the food storage container 10, the power receiving unit 111 is provided inside the bottom surface portion 12a of the container body 121 in the vacuum container unit 12, so that the food storage container 10 shortens the distance between the power receiving unit 111 and the power transmission device 20. and the efficiency of wireless power supply can be improved.
In the food storage container 10, the sensor 112 is also provided on the bottom surface portion 12a of the container body 121 in the vacuum container portion 12, similarly to the power receiving portion 111, and the sensor 112 and the power receiving portion 111 are in contact with each other. Therefore, in the food storage container 10, it is not necessary to use a cable to connect the power receiving unit 111 and the sensor 112. FIG. If power receiving unit 111 and sensor 112 are provided at separate positions, power receiving unit 111 and sensor 112 need to be connected by a cable. If the power receiving unit 111 and the sensor 112 are connected by a cable, the cable may become dirty or disconnected in the food storage container 10, for example. Dirty or broken cables may affect the quality of the food 3 in the vacuum vessel section 12 . Moreover, the sensor 112 may not be driven due to the cable becoming dirty or broken. When the sensor 112 is no longer driven, it becomes impossible to measure the characteristic values of the food 3 in the food storage container 10 .
The food storage container 10 eliminates the risk of contamination or disconnection of the cable by directly connecting the power receiving unit 111 and the sensor 112 with a terminal without using a cable.
Further, by providing the sensor 112 on the bottom surface portion 12a of the container body 121 in the vacuum container portion 12, when the food 3 is stored in the vacuum container portion 12, the food 3 and the sensor 112, more specifically, The measurement terminals 1122 of the sensor 112 can be easily brought into contact with each other. Specifically, the measuring terminal 1122 of the sensor and the sensor main body 1121 may be connected by a fitting type connector, or may be connected via a cable. A measuring terminal 1122 of the sensor 112 is attached so as to be in contact with the food. Moreover, the measurement terminal 1122 may be provided not only at one location but also at a plurality of locations. As a result, the food storage container 10 can detect the state of the food even when there are a plurality of foods or when the food is in the corner of the container. The user does not have to be conscious of the installation position of the sensor 112 when storing the food 3 in the vacuum container section 12 .

FIG. 5 is a flow chart for explaining the operation of the food quality measurement system 1 according to Embodiment 1. FIG.
Power transmission device 20 transmits power in a non-contact manner to power reception unit 111 provided in food storage container 10, and supplies power to power reception unit 111 (step ST501).
In food storage container 10, power receiving unit 111 receives power from power transmitting device 20 in a non-contact manner (step ST502). Power receiving unit 111 outputs power received from power transmitting device 20 to sensor 112 and control unit 113 .
In food storage container 10, sensor 112 is driven using the power output from power receiving unit 111 in step ST502, and measures the characteristics of food 3 in vacuum container unit 12 (step ST503). More specifically, the sensor 112 measures characteristic values of the food 3 inside the vacuum vessel portion 12 .
The sensor 112 outputs the measurement results of the characteristic values of the food 3 to the control section 113 .

Control section 113 is driven by the power output from power receiving section 111 in step ST502, and outputs quality information based on the characteristics measured by sensor 112 in step ST503 (step ST504).
Specifically, the control unit 113 causes the display unit 123 to display quality information based on the characteristic values measured by the sensor 112 .

In the first embodiment described above, in the food storage container 10, the display portion 123 is provided on the side surface of the container body 121 as shown in FIG. 1, but this is merely an example.
For example, in the food storage container 10 , the display section 123 may be provided on the lid 122 .
FIG. 6 is a diagram showing an example of an image of the food storage container 10 in which the lid 122 is provided with the display portion 123 in Embodiment 1. As shown in FIG. FIG. 6 is an image of a sectional view of the food storage container 10. As shown in FIG.
The food storage container 10 shown in FIG. 6 differs from the food storage container 10 shown in FIG. 1 in that a display portion 123 is provided on the lid 122 .
In this case, display unit 123 is not connected to power receiving unit 111 and control unit 113 through terminals. In this case, the display unit 123 includes a display-side power receiving unit (not shown) and a display-side receiving unit (not shown). The display-side power receiving unit receives power from the power transmitting device 20 in a non-contact manner. The display unit 123 is driven by the power received by the display-side power receiving unit. Also, the display-side receiving unit receives the quality information output by the control unit 113 by wireless communication. The display unit 123 displays the quality information received by the display-side receiving unit.
In the food storage container 10, the display unit 123 is provided on the lid 122, so that the user can easily check the quality information compared to the case where the display unit 123 is provided on the side surface of the container body 121. can. If the display unit 123 is provided on the side surface of the container body 121 , the user may have to bend down to check the display surface of the display unit 123 . When the display unit 123 is provided on the lid 122, the user can check the display surface of the display unit 123 from above the food storage container 10 in a comfortable posture without bending over.

Moreover, in Embodiment 1 described above, it was assumed that the food storage container 10 was provided with only one sensor 112, but this is merely an example.
Food storage container 10 may include multiple sensors 112 . For example, the food storage container 10 includes a sensor 112 for measuring the sugar content of the food 3, a sensor 112 for measuring the water content of the food 3, a sensor 112 for measuring the water content of the food 3, a sensor 112 for measuring the salt content of the food 3, Alternatively, two or more of the sensors 112 that measure the hydrogen ion concentration of the food 3 may be provided.
In this case, the sensor 112 outputs the measurement result to the control unit 113 in association with information that can identify the sensor 112 .
When the characteristic values of the food 3 are output from the plurality of sensors, the control unit 113 displays the quality information so that it can be seen which characteristic value was measured for which characteristic. Note that, if the sensor 112 can be specified, the control unit 113 can specify which type of characteristic the sensor 112 is measuring.
FIG. 7 is a diagram showing an image of another screen example of display unit 123 on which quality information is displayed by control unit 113 in the first embodiment.
The screen example shown in FIG. 7 is output by the control unit 113 when the food storage container 10 includes the sensor 112 for measuring the sugar content, the sensor 112 for measuring the water content, and the sensor 112 for measuring the salt content. It is an example of a screen displayed by the display unit 123 based on the quality information.
In the screen example shown in FIG. 4, the control unit 113 displays only the characteristic value of the sugar content, whereas in the screen example shown in FIG. and the salinity characteristic value are displayed.

Further, in the first embodiment described above, when the food storage container 10 includes a plurality of sensors 112, when displaying the quality information, the control unit 113 determines which sensor 112 is based on the characteristic value measured by the quality information. The quality information can be displayed on the display unit 123 so that the information can be understood.
For example, the control unit 113 displays information indicating the location of the sensor 112 that measured the characteristic value on the bottom surface 12a of the container body 121 in the vacuum container unit 12 together with the characteristic value. The sensor 112 outputs to the control unit 113, together with the characteristic value, information that enables the location of the sensor 112 on the bottom surface portion 12a to be specified.

Further, in Embodiment 1 described above, the control unit 113 displays the current characteristic values of the food 3 as quality information (see FIG. 4), but this is merely an example.
For example, the control unit 113 may display a history of measured characteristic values as the quality information.
For example, the control unit 113 associates the characteristic value measured by the sensor 112 with information about the acquisition date and time of the characteristic value, and stores the information in a storage unit (not shown) configured by a memory, for example. Then, for example, when causing the display unit 123 to output the quality information, the control unit 113 refers to the storage unit and acquires the history of the measured characteristic values. The control unit 113 includes the history of characteristic values acquired from the storage unit in the quality information. It should be noted that it is possible to appropriately set in advance how long the control unit 113 acquires information on characteristic values as a history of characteristic values. The quality information output by the control unit 113 indicates the characteristic values and characteristics of the food 3 to which the information on the date and time when the food was measured is given for a set period (hereinafter referred to as "history display period"). Information associated with information is included.
FIG. 8 is a diagram showing an image of a screen example of display unit 123 when control unit 113 displays a history of characteristic values as quality information in the first embodiment.

Further, in the first embodiment described above, for example, the control unit 113 outputs the characteristic value itself measured by the sensor 112 as quality information, but this is merely an example. For example, the control unit 113 may have a function of performing calculations based on characteristic values measured by the sensor 112, and information obtained as a result of the calculations may be included in the quality information.
Specifically, for example, the control unit 113 is provided with a calculation unit 1131 . FIG. 9 is a block diagram showing a configuration example of the control unit 113 including the calculation unit 1131 in Embodiment 1. As shown in FIG.
The calculator 1131 performs calculations based on characteristic values measured by the sensor 112 . Specifically, the calculator 1131 calculates the quality information based on the characteristic values of the food measured by the sensor.
The control unit 113 outputs quality information including characteristic values measured by the sensor 112 and calculation results based on the characteristic values performed by the calculation unit 1131 .

To give a specific example, for example, the calculation unit 1131 of the control unit 113 calculates information indicating the freshness of the food item 3 . In Embodiment 1, the information indicating the freshness of the food item 3 is, for example, the expiration date of the food item 3 .
For example, there is information (hereinafter referred to as "freshness calculation information") that is set in advance for each type of food 3 and each type of characteristic to be measured, at which characteristic value the expiration date will expire. It is assumed that it is generated and stored in a location that can be referred to by control unit 113 . For example, the freshness calculation information is generated by conducting a test using a prototype of the food 3 by a producer or the like and statistically analyzing the test result. The calculation unit 1131 calculates the expiration date of the food 3 based on the characteristic values measured by the sensor 112 and with reference to the freshness calculation information. Specifically, for example, the calculation unit 1131 calculates the number of days until the expiration date from the amount of change in the characteristic value and the freshness calculation information. Then, the calculation unit 1131 calculates the date after the calculated number of days has passed as the expiration date. The calculation unit 1131 may acquire information about the amount of change in characteristic values from the history of characteristic values stored in the storage unit.
The control unit 113 outputs quality information including, for example, the characteristic value measured by the sensor 112 and the expiration date calculated by the calculation unit 1131 to the output device. Specifically, control unit 113 causes display unit 123 to display quality information including the characteristic value measured by sensor 112 and the expiration date. The display unit 123 displays the characteristic values and the expiration date of the food 3 .

Further, for example, the calculation unit 1131 can also calculate the time when the food 3 is ready to be eaten. For example, for each type of food 3 and type of characteristic to be measured, information in which characteristic values are associated in advance with how soon the food 3 will be ready to eat (hereinafter referred to as "preferable timing information"). is generated and stored in a location that can be referred to by control unit 113 . For example, the producer or the like conducts a test using a prototype of the food 3 and generates the information on the timing of when the food is ready to eat by statistically analyzing the test results.
The calculation unit 1131 calculates the time when the food 3 is ready to eat, based on the characteristic values measured by the sensor 112 and referring to the ready-to-eat time information.
When the calculation unit 1131 calculates the time when the food 3 is ready to eat, the control unit 113 determines whether or not the time when the food 3 is ready to eat has arrived. When the time when the food 3 is ready to eat has arrived, the control unit 113 sends to the output device the characteristic value measured by the sensor 112 and the information indicating that the food 3 is ready to eat. Outputs quality information that can be Specifically, control unit 113 causes display unit 123 to display quality information including characteristic values measured by sensor 112 and information indicating that food 3 is ready to eat. The display unit 123 displays the characteristic values of the food 3 and the fact that the food 3 is ready to eat.

In the above-described specific example, the calculation unit 1131 calculates the time when the food 3 is ready to eat, based on the characteristic values measured by the sensor 112 and with reference to the information on the time when the food 3 is ready to eat. However, the method for calculating the time when the food 3 is ready to eat is not limited to this.
For example, for each type of food 3 and each type of property to be measured, information in which characteristic values are set when the food 3 is ready to eat (hereinafter referred to as "preferred price information") is generated, and the control unit 113 is stored in a location that can be referred to. The reasonable price information is generated by, for example, conducting a test using a prototype of the food 3 by a producer or the like and statistically analyzing the test results.
For example, the calculation unit 1131 may calculate the number of days until the food 3 becomes ready to eat from the change amount of the characteristic value and the ready-to-eat price information. Then, the calculation unit 1131 calculates the date after the calculated number of days has elapsed as the time when the food 3 is ready to be eaten.

Also, in the above-described specific example, the control unit 113 includes information indicating that the food 3 is ready to eat in the quality information, but this is only an example. The control unit 113 may include the time when the food 3 is ready to eat, calculated by the calculation unit 1131, in the quality information.

FIG. 10 shows an example of a screen of the display unit 123 on which the control unit 113 displays the expiration date of the food item 3 and quality information including information indicating that the food item 3 is ready to be eaten in the first embodiment. It is a figure which shows an image.
In FIG. 10, the control unit 113 causes the display unit 123 to display the comment "It's time to eat" so as to inform the user that the food item 3 is ready to eat (see 801 in FIG. 10). . Note that this is merely an example, and the control unit 113 may, for example, cause the display unit 123 to display an icon or the like to notify the user that the food 3 is ready to eat.
In FIG. 10, the quality information output by the control unit 113 includes the characteristic values of the food 3, the expiration date of the food 3, and information indicating that the food 3 is ready to be eaten. However, this is only an example. The control unit 113 may include the characteristic value, the expiration date of the food 3, or information indicating that the food 3 is ready to eat in the quality information. Further, the control unit 113 may include the expiration date of the food 3 and information indicating that the food 3 is ready to be eaten without including the characteristic value of the food 3 in the quality information. Instead of including the characteristic value of the food 3, the information may include either the expiration date of the food 3 or information indicating that the food 3 is ready to be eaten.

In addition, although the display unit 123 is provided in the food storage container 10 in Embodiment 1 above, it is not essential that the display unit 123 is provided in the food storage container 10 . The food storage container 10 may not include the display section 123 .
For example, the display unit 123 may be provided outside the food storage container 10 at a location where the food storage container 10 can be referenced. As a specific example, the display unit 123 may be a display unit provided in a PC (Personal Computer) used by the user, or may be provided in a mobile terminal such as a smartphone or a tablet device owned by the user. It is good also as a display part which has been carried out. In this case, the control unit 113 causes the display unit 123 to display the quality information by wireless communication via the communication unit.

In the first embodiment described above, the display device (display unit 123) is used as the output destination of the quality information, and the food storage container 10 displays the quality information. The output method is not limited to display. For example, the output destination of the quality information may be an audio output device (not shown) such as a speaker, and in the food storage container 10, the control unit 113 may output the quality information from the audio output device via the communication unit. . For example, the audio output device may be provided in the vacuum container unit 12 and connected to the power receiving unit 111 and the control unit 113 by terminals. The storage container 10 may be provided at a location that can be referenced and may be connected to the food storage container 10 by wireless communication.
Further, for example, a storage unit (not shown) may be used as the output destination of the quality information, and the control unit 113 may store the quality information in the storage unit via the communication unit. The storage unit may be provided in the food storage container 10 or may be provided in a place outside the food storage container 10 where the food storage container 10 can be referred to.

Also, in the first embodiment described above, the timing at which the control unit 113 outputs the quality information can be an appropriate timing.
For example, the control unit 113 may always output the quality information while the power receiving unit 111 is receiving power, or may output the quality information at preset timing such as every other day. may When the quality information is output at preset timing, the control unit 113 stores the characteristic values of the food 3 measured by the sensor 112 in the storage unit, and at the preset timing, stores the storage unit. Refer to it and output the quality information.
Also, for example, the control unit 113 may output the quality information when receiving an instruction from the user. The user inputs an instruction to output quality information from an input device (not shown) at the timing when the user wants to check the quality of the food 3 . The input device is, for example, the display section 123 of the food storage container 10 . The display unit 123 is assumed to be a touch panel display. The user inputs the output instruction by, for example, touching the display unit 123 . For example, the input device may be a mouse, keyboard, or the like provided in the PC.
A reception unit (not shown) included in the food storage container 10 receives the output instruction input by the user from the input device, and outputs information to the effect that the output instruction has been received to the control unit 113 . The control unit 113 outputs the quality information when the receiving unit outputs information indicating that the output instruction has been received.
For example, when the control unit 113 outputs a history of measured characteristic values as quality information, the user may be allowed to specify the period of the history of characteristic values output by the control unit 113 .

In the first embodiment described above, in the food storage container 10, the power receiving unit 111, the sensor 112, and the control unit 113 among the constituent units of the measurement control device 11 are integrated into a module, and the vacuum container unit 12 is provided inside the bottom portion 12a of the container body 121 in (see FIG. 1). Alternatively, for example, the measurement control device 11 may be installed on the bottom surface portion 12 a of the container body 121 in the vacuum container portion 12 .
FIG. 11 illustrates an image of an example of the food quality measurement system 1 in which the measurement control device 11 of the food storage container 10 is installed on the bottom portion 12a of the container body 121 in the vacuum container portion 12 in the first embodiment. It is a figure for doing. FIG. 11 shows a cross-sectional image of the food storage container 10 .
The measurement control device 11 is installed in the same space as the space in which the food 3 is stored inside the container body 121 of the vacuum container section 12 .

Further, in the first embodiment described above, the food storage container 10 accommodates one food item 3 (apple in FIG. 1) inside the vacuum container portion 12, but this is merely an example. The food storage container 10 can also store a plurality of foods 3 inside the vacuum container portion 12 . In that case, there may be a plurality of types of foodstuffs 3 . For example, the food storage container 10 may store two apples and one lemon inside the vacuum container portion 12 .
For example, the sensor 112 outputs the characteristic value to the control unit 113 in association with information indicating at which position of the bottom surface portion 12a of the container body 121 in the vacuum chamber portion 12 the measurement was performed. For example, in the quality information, the control unit 113 associates a plurality of characteristic values with information indicating at which position on the bottom surface portion 12a of the container body 121 in the vacuum container portion 12 the measurement was made. Then, for example, the control unit 113 causes the display unit 123 to display the characteristic value in association with information indicating at which position of the bottom surface part 12a of the container body 121 in the vacuum container unit 12 the characteristic value was measured. Thereby, the user can grasp which characteristic value is measured for which food 3 among the plurality of foods 3 .
For example, the bottom surface portion 12a of the container body 121 in the vacuum container portion 12 is divided into a plurality of areas. Register whether it is stored inside. For example, the user may touch the display unit 123 to register information about the area in which the food 3 is stored. The reception unit of the food storage container 10 stores the information of the area in which the food 3 is stored, which is registered by the user, in the storage unit. For example, when outputting the quality information to the display unit 123, the control unit 113 refers to the storage unit and associates the information of the area where the food 3 is stored with the characteristic value. The display unit 123 displays the characteristic values and the areas in association with each other. As a result, the user can view the screen displayed on the display unit 123 without opening the lid 122 of the vacuum chamber unit 12, and the position of the bottom surface part 12a of the container body 121 in the vacuum chamber unit 12 where the characteristic value is. After grasping which food 3 was measured and which area of the vacuum container part 12 is stored, the characteristic value measured for each food 3, in other words, the quality of each food 3 is determined. can be confirmed.

Also, in Embodiment 1 above, the food storage container 10 is provided with the exhaust port 1221 with a check valve, but this is merely an example. The food storage container 10 does not necessarily have the exhaust port 1221 with a check valve. In the food storage container 10, it is sufficient that the vacuum container portion 12 is in a vacuum state by the container body 121 and the lid 122.

As described above, according to Embodiment 1, the food storage container 10 has the lid 122 and the container body 121, the vacuum container portion 12 capable of storing the food 3 in a vacuum state, and the power transmission device 20. A power receiving unit 111 capable of receiving power in a non-contact manner, a sensor 112 for measuring characteristic values of the food 3 stored in the vacuum container unit 12 based on the power received by the power receiving unit 111, and the characteristics of the food measured by the sensor 112. and a control unit 113 that outputs quality information based on the value. Therefore, the food quality measurement system 1 can present information that enables confirmation of the quality of the food 3 while maintaining the vacuum state.

Duplicate description is omitted. In addition, in FIG. 12, since each component of the food storage container 10 is the same as each component shown in FIG. 1, the illustration of the reference numerals is omitted. In the following description, the

food storage containers

10a and 10b are collectively referred to as the food storage container 10 as well. Also, the

power transmission devices

It is also called a transmission device.

The first food storage container wirelessly receives power from the first power transmission device. The second food storage container wirelessly receives power from the second power transmission device.
Since the mechanism of wireless power supply in the food quality measurement system 1a has already been explained in the first embodiment (see FIG. 3), redundant explanations will be omitted.

The food quality measurement system 1a according to Embodiment 2 differs from the food quality measurement system 1 according to Embodiment 1 in that a wireless device 1001 is provided. Wireless device 1001 is provided in refrigerator 4, for example. Note that this is merely an example, and the wireless device 1001 may be provided in a server that is wirelessly or wiredly connected to the refrigerator 4, for example.
The wireless device 1001 may include a control unit (not shown), a storage unit (not shown), and a communication unit (not shown). The control unit is configured by a processor such as a CPU (Central Processing Unit), for example. The storage unit is configured by memories such as ROM (Read Only Memory), RAM (Random Access Memory), and flash memory, for example. The communication unit is configured by a communication device that performs wireless communication such as LTE (Long Term Evolution).
The control unit provided in the wireless device 1001 lists the quality information output from the plurality of food storage containers 10, in other words, the first food storage container and the second food storage container, and lists the listed information (hereinafter " list information”) to the communication unit of the wireless device 1001 . Then, the communication unit of wireless device 1001 outputs the list information to information device 2000 outside refrigerator 4 . Wireless device 1001 may directly output the quality information output from the first food storage container and the second food storage container to information device 2000 , and list the quality information on information device 2000 .
Information equipment 2000 is, for example, a PC or a mobile terminal. The information equipment 2000 may include a display unit (not shown in FIG. 13). The display unit of the information device 2000 displays list information.
Wireless device 1001 generates list information based on the quality information output from the first food storage container and the second food storage container. Specifically, the list information is, for example, a list of characteristic values for each type of food 3 or for each characteristic measured by the sensor 112 of the first food storage container and the sensor 112 of the second food storage container. This is the information shown. In addition, in Embodiment 2, control unit 113 of food storage container 10 outputs quality information to wireless device 1001 .

For example, the wireless device 1001 supplies the list information to the information device 2000 as shown in FIG. A list is displayed in which characteristic values of the food 3 measured in the storage container and the second food storage container are associated with each other. The list information includes information in which characteristic values of the food 3 measured in each food storage container 10 and information indicating the characteristics of the food 3 are associated with each characteristic of the food 3 . The list information may further include information about the dates and times when the characteristic values were measured.

The wireless device 1001 causes the information device 2000 to display the list information, so that the user can see inside the vacuum vessel portion 12 of each food storage container 10 in the refrigerator 4 from the outside of the refrigerator 4 without opening the door of the refrigerator 4. The quality of the food 3 stored in the container can be confirmed at a glance.

The timing at which the wireless device 1001 outputs the list information can be an appropriate timing.
For example, the wireless device 1001 may always output the list information while the power receiving unit 111 is receiving power, or may output the list information at preset timing such as every other day. may When outputting the list information at preset timing, the wireless device 1001 stores the quality information output from each food storage container 10 in a storage unit (not shown), for example. Then, at a preset timing, the wireless device 1001 refers to the storage unit, generates list information from the stored quality information, and outputs the generated list information.
Further, for example, the wireless device 1001 may output the list information based on an instruction from the user when receiving an instruction from the user. The user inputs an instruction to output list information from an input device (not shown) at the timing when the user wants to check the quality of each food item 3 stored in the refrigerator. The input device is, for example, the display section of the information equipment 2000 . The display unit of the information equipment 2000 is, for example, a touch panel display. The user inputs the output instruction by, for example, touching the information device 2000 . For example, the input device may be a mouse, keyboard, or the like provided in the PC. A reception unit (not shown) included in the food quality measurement system 1 a receives an output instruction input by the user from the input device, and outputs information to the effect that the output instruction has been received to the wireless device 1001 . The wireless device 1001 outputs the list information when the receiving unit outputs information indicating that the output instruction has been received.

For example, wireless device 1001 may include a history of measured characteristic values in list information. For example, the wireless device 1001 can cause the information device 2000 to list and display the progress of the measured characteristic values based on the list information including the history of the measured characteristic values.
Further, for example, the wireless device 1001 is provided with the function of the calculation unit 1131, and the list information indicates that the food 3 stored in the vacuum container unit 12 of each food storage container 10 is ready to eat. or the expiration date may be included. For example, the wireless device 1001 is stored in the vacuum container portion 12 of each food storage container 10 based on information notifying the information device 2000 that it is ready to eat or list information including the expiration date. The characteristic value of the food 3 stored in the table can be associated with information indicating that it is ready to eat or the expiration date, and can be listed and displayed.

Further, in Embodiment 2, the control unit 113 included in each food storage container 10 can output quality information to the information device 2000 via the wireless device 1001 .
For example, the control unit 113 included in each food storage container 10 can cause the information device 2000 to display quality information. The information device 2000 individually displays the quality information about the food 3 stored in the vacuum container portion 12 of the food storage container 10 . A user can individually check the quality of the food 3 stored in the vacuum container part 12 of the food storage container 10 in the refrigerator 4 from the outside of the refrigerator 4 without opening the door of the refrigerator 4. .
In this case, the user can specify the desired food storage container 10 from the information device 2000 and display only the quality information about the food 3 stored in the vacuum vessel portion 12 of the specified food storage container 10. can.
For example, the user may specify the desired food storage container 10 by the same method as inputting the list information output instruction as described above. That is, for example, the user inputs information specifying a desired food storage container 10 and an instruction to output the characteristic values of the food 3 in the specified food storage container 10 from the information device 2000 . The reception unit receives information input by the user, and the wireless device 1001 outputs quality information output from the control unit 113 of the designated food storage container 10 .

In each food storage container 10 , the sensor 112 outputs the measurement results of the characteristics of the food 3 to the controller 113 . The specific operation of step ST1403 in each food storage container 10 is the same as the specific operation of step ST503 in FIG. 5 already explained in the first embodiment.

In each food storage container 10, control unit 113 is driven by the power output from power receiving unit 111 in step ST1402, and outputs quality information based on the characteristics of food 3 measured by sensor 112 in step ST1403 (step ST1404).
Specifically, the control unit 113 causes the display unit 123 to display the quality information. The specific operation of step ST1404 in each food storage container 10 is the same as the specific operation of step ST504 in FIG. 5 already explained in the first embodiment.

The wireless device 1001 outputs list information listing the quality information output from each food storage container 10 in step ST1403 (step ST1405).

In addition, in the food quality measurement system 1a, the operation of step ST1404 described above may be omitted.
