Abstract
A vacuum insulator (10) includes: a core (13); a pressure sensor (51) that detects a pressure; a transmitter (52) that transmits, by wireless communication, the detected pressure detected by the pressure sensor (51); a power feeder (53) that feeds electric power to the pressure sensor (51) and the transmitter (52); and an outer skin (14), an inside of which is decompressed, the outer skin (14) accommodating therein the core (13), the pressure sensor (51), the transmitter (52), and the power feeder (53), the outer skin (14) having gas barrier capability.
Claims14
A vacuum insulator comprising:
- an outer skin formed of a non-metal material;
- a core;
- a pressure sensor that detects a pressure;
- and
- a transmitter that transmits, by wireless communication, the detected pressure detected by the pressure sensor, wherein
- the vacuum insulator is in a shape of a box, and includes a lower wall and four side walls,
- the outer skin comprises:
- an inner member that is in a shape of a box whose upper end is open;
- and
- an outer member that is in a shape of a box whose upper end is open,
- the inner member and the outer member are combined together to form a communication space in which an interior space of the lower wall between the inner member and the outer member and interior spaces of the respective four side walls between the inner member and the outer member communicate with each other,
- the core is provided in the communication space, and
- the transmitter is provided in a part of the communication space, the part corresponding to none of the four side walls but to the lower wall.
A testing system comprising:
- a vacuum insulator;
- and
- a tester on which the vacuum insulator is placed, wherein
- the vacuum insulator includes:
- an outer skin formed of a non-metal material;
- a core;
- a pressure sensor that detects a pressure;
- a transmitter that transmits, by wireless communication, the detected pressure detected by the pressure sensor;
- and
- a power receiving coil that receives, from outside, electric power that is fed to the pressure sensor and the transmitter,
- the vacuum insulator is in a shape of a box, and includes a lower wall and four side walls,
- the outer skin includes:
- an inner member that is in a shape of a box whose upper end is open;
- and
- an outer member that is in a shape of a box whose upper end is open,
- the inner member and the outer member are combined together to form a communication space in which an interior space of the lower wall between the inner member and the outer member and interior spaces of the respective four side walls between the inner member and the outer member communicate with each other,
- the core is provided in the communication space,
- the pressure sensor, the transmitter, and the power receiving coil are provided in a part of the communication space, the part corresponding to none of the four side walls but to the lower wall, and
- the tester includes:
- a receiver that receives the detected pressure transmitted from the transmitter;
- and
- a power transmitting coil that transmits electric power to the power receiving coil.
