摘要:
In a conventional vacuum heat-insulating members capable of measuring physical properties of the inside thereof using a sensor or the like, it is impossible to charge a battery which is provided thereinside to supply electric power to the sensor and others. Moreover, there is another technical problem that, if an internal space of the vacuum heat-insulating member is excessively occupied by the sensor and the battery, the volume of closed cells of a core formed by fibers is reduced and becomes insufficient, thereby leading to difficulty in preventing an inflow of gas from the outside. In order to solve the above technical problems, the present invention provides a vacuum heat-insulating member internally provided with a small-size wireless vacuum gauge comprising: a pressure sensor which is a thermocouple vacuum sensor, or a piezoresistive vacuum sensor, or a crystal vacuum sensor, or a combination of two or more of them; a battery; a battery charging unit; and a transmission unit for transmitting measurement data including at least a pressure value, wherein the pressure sensor is formed by microelectromechanical system (MEMS) techniques, and the battery charging unit is configured to charge the battery without any electrical connection with an external power source.
