[Problems to be solved by the device]

 However, users such as ordinary households have a desire to know not the billed electricity bill but the charge as it is actually used and accumulated. If you know the process of totaling, you will be motivated to save money, and you can try to use electricity rationally. In the conventional power meter, the actual process of accumulating electricity charges, individual power consumption of electric appliances, and electricity charges cannot be easily grasped in a concrete manner. Electricity charges are public charges, but they fluctuate due to social conditions and supply company conditions, and due to the introduction of new taxes (consumption tax introduction), real charges fluctuate depending on what time. At home, there is no guideline for budgeting electricity bills and which appliances to save. There are demands from users for reasonable savings and wasteful use of electric appliances, and there is a demand for electricity meters that display electricity charges for each electric appliance.

[Effect of device]

 As explained above, the present invention allows real-time visual confirmation of the power consumption and electricity charges of individual electric appliances such as TVs and air conditioners, and is a very useful idea for motivation for saving electricity. It has the following effects.

Since the power consumption when using an electric appliance can be visually recognized, an abnormality of the electric appliance itself can be detected when the maximum power consumption described in the catalog of the electric appliance is exceeded. In addition to the individual electricity consumption, consumption tax addition and basic charge display are used together, so the actual amount paid is displayed. The value obtained by simply multiplying the power consumption by the unit price is different from the actual payment fee, and it is important to be aware of the basic fee. In the present invention, all of these displays are displayed, which is kind. Of course, it is possible to omit a part of this display. The power consumption from the outlet is used as a signal for operation, so even if the TV is switched on, turned off, and then switched on again, the memory function can be used to calculate the power consumption, consumption time, and total electricity bill. Since the totals are accumulated and the start date of use is set, it is possible to easily recognize the long-term total use time and frequency of electric appliances used at irregular intervals. A figurine type structure in which only the display part is formed on the front surface and the stabilizing frame is provided can be always recognized by placing it on the side of the electric equipment. It is easier to use a device that has a column for the name of the appliance because it is less likely to make a mistake.
