Abstract

<P>PROBLEM TO BE SOLVED: To securely stop an electrical device when it exceeds durable years. <P>SOLUTION: In a life monitoring device 2 incorporated in the electrical device 1, a latching relay 21 closes a power supply path to a main function part 100 in the electrical device 1. At the time of shipping the electrical device 1, a manufacturer depresses an operation key 22, and a timer part 20 is started. The timer part 20 clocks a lapse time from starting time after shipping. When the lapse time from starting time reaches the life time, the timer part 20 outputs a break signal to the latching relay 21. When the break signal is inputted, the latching relay 21 cuts the power supply path from a power supply AC to the main function part 100. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a life monitoring device for monitoring the life of an electric device, an electric device in which the life monitoring device is incorporated, and a life monitoring system including the life monitoring device.

  In an electric device that operates by supplying power from a power source, deterioration due to the use of components usually occurs. For this reason, the manufacturer's side sets the accumulated energization time that can be used for the electrical equipment. Therefore, there is a need for a device that monitors the cumulative energization time of electrical equipment.

As a conventional device that monitors the cumulative energization time of an electric device, a device that notifies a manufacturer or a recycler that the electric device is at the end of its life when the energization time of the electric device exceeds a predetermined value is known. (For example, patent document 1).
Japanese Patent Laid-Open No. 11-127252 (paragraph 0021 and FIG. 6)

  However, electrical equipment not only deteriorates due to use but also deteriorates with time even when it is not used. In the conventional apparatus, since only the cumulative energization time of the electric device is measured, there is a problem that the life of the electric device due to deterioration with time cannot be grasped.

  As a conventional method for solving the above problems, the manufacturer describes the life time in the instruction manual, and the elapsed time from the shipment start time or use start time is described in the instruction manual from the shipping time or the start date of use. If the customer assumes that the lifetime has been exceeded, there is a way for the customer to stop using the electrical equipment.

  However, in the above method, even if the lifetime set by the manufacturer is exceeded, it seems that the device is operating normally unless a problem occurs, so the customer often does not stop using the electric device. Also, even if the customer wants to check the lifetime, if the instruction manual has already been lost, the lifetime of the electrical device could not be confirmed.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a life monitoring device, an electric device, and a life monitoring system capable of reliably stopping the electric device when the electric device exceeds the useful life.

(Embodiment 1)
First, the configuration of the first embodiment will be described with reference to FIGS. As shown in FIG. 1, the electrical device 1 according to the present embodiment includes a device main body 10 that houses a main functional unit 100 that is operated by power supply from a power source AC, and a plug 11 that is connected to the device main body 10 via a cord 101. And. The plug 11 is detachably connected to an outlet C that is electrically connected to the power source AC via the power supply line L. The main function unit 100 is operated by electric power supplied from the power source AC through the plug 11 connected to the outlet C. The power supply line L constitutes a part of a power supply path from the power source AC to the electrical device 1.

  In addition to the main function unit 100, the device main body 10 incorporates a life monitoring device 2 for monitoring the life of the electrical device 1.

  The life monitoring device 2 includes a timer unit (timer unit) 20 that counts an elapsed time from startup, and a latching relay (switch unit) that is inserted into the power supply path from the power source AC to the main function unit 100 of the electrical device 1. 21, an operation button (operation means) 22 for starting the timer unit 20, and an internal battery 23 that supplies power to the timer unit 20 and the latching relay 21.

  The internal battery 23 counts the timer unit 20 and supplies power necessary for driving the latching relay 21. For example, power can be supplied to the timer unit 20 and the latching relay 21 even when power is not supplied to the main function unit 100 of the electrical device 1 such as at the time of inventory.

  The timer unit 20 is activated when the operation button 22 is pressed, and measures the elapsed time from the activation. When the elapsed time counted by the timer unit 20 reaches a preset life time, the timer unit 20 sends a break signal for interrupting power supply from the power source AC to the main function unit 100 to the latching relay 21. Output. In the present embodiment, the preset life time means an elapsed time (for example, 10 years) from the time of shipment of the electric device 1 set by the manufacturer.

  The latching relay 21 conducts the power supply path from the power source AC to the main function unit 100 when the set signal is input, while the power supply path from the power source AC to the main function unit 100 when the break signal is input. Disconnect.

  Further, the life monitoring apparatus 2 is accompanied by a medium 24 in which individual device identifiers (management numbers in FIG. 2) as shown in FIG. Different device identifiers are allocated and issued individually. The medium 24 is attached as a seal to the housing (not shown) of the device main body 10 or the plug 11. Thereby, the customer can identify the device identifier and know that the life of the electrical device 1 is being monitored. The medium 24 is not limited to a seal, and may be a QR code, for example. Further, the medium 24 may be a recording medium stored in the life monitoring apparatus 2. In this case, the customer can identify the device identifier by connecting the life monitoring device 2 to a personal computer or the like and electrically taking the device identifier recorded on the recording medium into the personal computer.

  Next, the operation of this embodiment will be described with reference to FIG. At the stage where the life monitoring device 2 is incorporated in the device main body 10 of the electrical device 1, the latching relay 21 is in a state where the power supply path to the main function unit 100 is closed. Thereafter, when shipping the electrical device 1 incorporating the life monitoring device 2, the operation button 22 is pressed by the manufacturer, and the timer unit 20 is activated. After the shipment, the timer unit 20 measures the elapsed time from the start-up. Thereafter, when the elapsed time from the start reaches the lifetime, the timer unit 20 outputs a break signal to the latching relay 21. The latching relay 21 cuts off the power supply path from the power source AC to the main function unit 100 when a break signal is input.

  As described above, according to the present embodiment, when the elapsed time from the activation of the timer unit 20 reaches the lifetime, the latching relay 21 disconnects the power supply path from the power source AC to the electrical device 1, thereby Since the power supply from the AC to the electric device 1 can be cut off, the electric device 1 can be surely stopped when the electric device 1 exceeds the useful life.

  In addition, since the timer unit 20 can be accurately set by operating the operation button 22, the life of the electric device 1 can be accurately monitored.

  As a modification of the first embodiment, as illustrated in FIG. 3, a latching relay 21 that receives only a break signal from the timer unit 20 may be used. Also in this modification, as in the first embodiment, the latching relay 21 disconnects the power supply path from the power source AC to the electrical device 1 when the elapsed time from the start of the timer unit 20 reaches the lifetime. As a result, the power supply from the power source AC to the electric device 1 can be cut off, so that the electric device 1 can be surely stopped when the electric device 1 exceeds the useful life.
