Description

  The present invention relates to a washing machine charge device that can charge for the use of a commercially available washing machine.

  Conventionally, when using electrical products such as commercial TVs, air conditioners, refrigerators, washing machines, etc. in places other than home (for example, dormitories, etc.), power is supplied by inserting coins or inserting prepaid cards, and timer timing ends. Until then, fee-charging devices that charge for the use of electric products, which allow them to be used, have been widely used. Among these fee-charging devices, there are known devices that do not incur a burden such as wasteful expenditure on the user by detecting the current consumption of the electric product.

  For example, Patent Documents 1 to 3 disclose fee-charging devices that do not cause a burden of unnecessary expenditure on users. Specifically, in Patent Document 1, when a coin is inserted, power is supplied to the television, current consumption of the television is detected, and when the detected value is less than a predetermined value due to temporary interruption of viewing of the television, the timer is stopped. A device (coin timer device) is disclosed. In Patent Document 2, when a prepaid card is inserted, power is supplied to the air conditioner, the current consumption of the air conditioner is detected, and the usage time corresponding to the current consumption is subtracted from the possible usage time (prepaid card device) Is disclosed. In Patent Document 3, when a prepaid card is inserted, power is supplied to an electric product (connection device) such as a television or a refrigerator, and the current consumption of the electric product is detected, and the time is measured only when the current consumption exceeds a predetermined value. A device (charging device) is disclosed.
