Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a power supply system for electrical equipment in a house or building.
be equipped with indicator lights and keys to prevent fires caused by electrical equipment when the house or building is unoccupied;
This invention relates to a power supply disconnection device for electrical equipment aimed at energy saving.

Conventionally, in a house or building, the power source for each electrical device is
It is assumed that a person directly operates the switch on the electrical equipment to disconnect or connect it. Therefore, before the house or building becomes unoccupied,
If we have forgotten to cut off the source line, the current situation is that the only way to restore it is for the person who forgot to recall the fact of forgetting and to take measures.

In this way, if one forgets to turn off the power supply system, the safety of the house in an unoccupied state is not guaranteed. The disadvantage is that the operation can only be done manually.

The present invention aims to prevent fires caused by overheating of electrical equipment (for example, electric heaters such as stoves and irons) that people forget to turn off when the house or building is left unattended. We aim to contribute to energy conservation by preventing the occurrence of electrical equipment and preventing the use of unnecessary electrical equipment, and conversely, to prevent electrical equipment that is used immediately (e.g., air conditioners in houses, The present invention provides a solution to the problem of the lighting (lighting furnace inside a building) being brought into contact with the building by two means: checking the indicator light and locking the door.

That is, the present invention provides an LED indicator light provided near the lock of the door inside and outside of a shed or building, a circuit having a cam mechanism and a limit switch built into the door lock, and a cable connected to the circuit. Embodiments of the present invention will now be described with reference to the drawings.

In the figure, 1 indicates a commercial AC power supply, 2 indicates a regular load,
This includes electrical equipment that needs to be used even when unattended, such as refrigerators, electric clocks, water tank pumps, etc. in buildings, and non-J equipment in buildings. These are electrical equipment that does not need to be used, but needs to be used immediately when the person becomes manned, and includes the air IM in the house, the controller, and the internal lighting in the house. 4 is manned load, which refers to electrical equipment that is used only when manned, that is, when unmanned, there is a risk of causing a disaster if used for convenience, and is a regular load above md of general electrical equipment. 2 and semi-regular load 3 are excluded.

5 can be housed in the refrigerator with a distribution board, but wiring has been installed in advance to distribute power from the open power supply 1 to the regular load 2, the office load 3, and the 1st person 4dl 4 system. Free cargo 3
In addition, a power relay 6 which operates in conjunction with a signal generated by a pure locking 7 or unlocking is installed in series in the system of the Kikujin load 4, respectively. 7 is the LHD & indicator box, and should be installed in an easily visible position on the H side of the house or building and near the lock on the outside door.For semi-normal load 3, green LED & indicator light 8
For 4 manned loads, use door color LED lighting 9.
shall be used and displayed.

The key 10 operates by locking and unlocking the opening/closing mechanism.
Built-in cams and limit switches generate opening/closing electrical signals, which actuate the power relay 6 of the distribution board 5 via the cable, which in turn lights up the LED display indicator ED. Here, when the key 10 is locked, the power relay 6 of the distribution board 5 is opened, and when the key 10 is unlocked, the power relay 6 of the distribution board 5 is closed.

If the LED indicator light 9 is lit at the time when the house or building is unoccupied, it means that the electrical equipment of the manned load is connected to the power supply.
It is desirable for the person to return indoors and turn off the power switch of the relevant electrical equipment, but if there is no time or it is difficult, please lock the door from outside and then turn off the power switch of the relevant electrical equipment. Just make sure that the red LED display has disappeared.

In addition, when the key 10 is locked indoors at night with someone present, it is necessary to keep the full load in contact with the key 10.
A 12-push button manual switch with a break contact is provided on the indoor side of the key 10, and by operating the switch, the power relay 6 of the distribution board 5 is prevented from operating.

Furthermore, on the other hand, if there is no obstacle on the straight line connecting the distribution board 5 and the key 10, a transmitter can be connected to the key 10 and a receiver can be installed to the distribution board 6 instead of the cable connecting the two in this embodiment. It is also possible to implement wireless signal transmission using a specific frequency.

As explained above, the present invention not only displays the usage status of each group of electrical equipment, but also locks and unlocks the key.
When the house or building becomes unoccupied by configuring the power supply system of the electrical equipment to be disconnected,
This has the effect of not only preventing fires caused by electrical equipment, but also contributing to energy savings.

Claims (1)

[Claims] Used in single-family houses, housing complexes, condominiums, private rooms in hotels, hospitals, etc. (hereinafter referred to as houses), and independent buildings such as radio station buildings, warehouses (hereinafter referred to as buildings). In addition to displaying the disconnection status of the power supply system of electrical equipment near the entrance/exit door, the door will be locked when unattended.
An electrical equipment power supply system disconnection device, characterized in that the power supply system of the electrical equipment is disconnected, and conversely, the power supply system of the electrical equipment is connected by unlocking when the equipment becomes manned.
