Description

[Detailed Description of the Invention] The present invention relates to a microwave oven that detects opening operations of windows and doors.
It is something that

It is important to automatically detect the opening of windows and doors in buildings such as houses, and various ranges for this purpose have been developed and put into practical use. There is.

However, power supply is a problem with both of them. In other words, external power supplies do not interfere with daily life activities,
And don't wire the In-j Reno 7 without interfering with the IFI.
Because of this, not only is the wiring work extremely troublesome, but there is also the risk that the detection function will be lost due to the wiring cut or 3L contact.

However, there are some drawbacks to those with a built-in battery, such as the battery having a limited lifespan, requiring periodic replacement, or malfunction due to insufficient voltage.

This invention was made in view of the above-mentioned circumstances, and when the window or p is opened, energy is stored, and when it reaches a certain level, it starts to be released and causes damped vibration. Spring e

In particular, our goal is to provide a compact and unobtrusive product that does not require a power source.

Hereinafter, this invention will be explained in detail with reference to the drawings.

In this case, when the window is closed), the magnet 2 is in the state where the spring 1 is extended.

The oscillating section 4 includes a diode 11 as shown in FIG.
A rectifying and smoothing circuit is constructed by connecting 12, and an oscillator 13 and an 7) 14 are sequentially connected to the output side of the child, and 3 J' are connected to the input side of the rectifying and smoothing circuit. There is C. Therefore, the voltage generated by I, 1, 3, t, J, and JL1 is rectified and converted to direct current, and the power supply type 1 of the oscillator 13 that operates with a minute h'ili force C is used, and the opening operation of window A is performed. Generates a signal indicating that tI is being performed.
There is C.

Next, we will discuss the operation. First, when the window is closed, the permanent magnet 2 on the side of the window A is attracted to the magnetic plate 5 on the side of the window frame [3], and is not affected by slight vibration.

In this state, an electric current 11- is not induced in the =1 ile 3, and the oscillator 13 (is in an inactive state).

−lj, when the opening operation of the window Δ is performed, the window Δ is closed between (
However, up to a certain distance 1llllt, the magnet 2 moves Cd while being attracted to the magnetic rI plate 5, but when it becomes erratic, the suction force resists the force of the spring 1. So, magnet 2 magnetizes'

During this time, the spring 1 accumulates energy with the opening/i-statement operation to the window, and due to the attraction of y1' at a certain distance (when the magnetic T12 separates from the magnetic plate 5, the magnetic 7jz, the second

An electric current L[ is induced in the permanent magnet 2 (1 return to work) and is guided to the oscillator 4. Nden 4〕1
2, it is converted into direct current and applied to the oscillator 13 as a power supply voltage. When the power supply type It is induced in this way, the oscillator 13 operates, and its single oscillator output is used by the amplifier 14. /+9.1 of this oscillation output. FI means the opening operation of the window Δ, 15s.
/, j, etc. (U L, the notification operation i-j C, the opening operation of the window △ automatically, and the power supply wiring), the built-in battery can be detected e. .

In addition, in order to convert the output of the oscillator 13 into an open operation detection signal, as shown in FIG.
It may be connected to the output terminal of the window, in which case the opening of the window can be perceived directly by the hepar output.

), and in reality, Jinri is going to change the structure to XJ Park 1. Contrary to what is shown in the drawings, the same relationship with respect to the installation of the R1 spring 1 should be made so that the energy of the spring 1 is stored by compression.

According to this invention, the force generated by windows and doors is stored in a coil spring, and this is converted into electric power by a permanent magnet coil and used as a power source for an oscillator. Therefore, there is no need for an external power source or battery, and there is no need for a power outage due to a loss of power, which greatly improves reliability. In addition, since the structure is deep inside the cylinder, it is compact.
It is possible to adopt a new configuration, and it is also easy to manufacture at a low cost.
