Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a non-use detection device for an iron, which detects whether an iron or the like is being used or not.

BACKGROUND OF THE INVENTION Conventional unused sensors of this type are, for example, disclosed in Japanese Utility Model Application No. 157-
Mercury switches such as those shown in Publication No. 132583 were the mainstream.

Problems to be Solved by the Invention Although the mercury switch shown above is technically established and highly reliable, it has a bad social image because it uses mercury, and it is difficult to dispose of it. However, it is generally difficult to use because of many problems such as recovery processing.

Means for Solving the Problems In order to solve the above problems, an elastic supporting mountain means is provided, and a magnetic detection means detects vibrations of the magnet caused by vibrations caused by the use or non-use of the iron.

Effects The present invention provides an easy-to-use non-use detection device for an iron, which uses the above-described means and has a configuration that does not use mercury, and can use magnetic detection means to prompt horizontal and vertical movements during ironing operations.

Embodiment FIG. 1 is a block diagram showing an embodiment of the non-use detection device for an iron according to the present invention. In FIG. 1 (-), one end of the elastic support 3 is fixed to the fixing part 1 by a regular female screw 2. As shown in FIG. Further, a magnet 4 is attached to the other end, and a reed switch 6 constituting magnetic detection means is arranged opposite to the magnet 4. The reed switch 6 is such that when magnetic flux passes between opposing electrodes, the electrodes are electrically closed (hereinafter referred to as "on"), and when no magnetic flux passes through, the electrodes become electrically open (hereinafter referred to as "off"). . Also the first
Figures (-) indicate when the iron is used horizontally as shown in Figure 1 (b), and Figure 2 (→) shows the state when the iron is used horizontally as shown in Figure 1 (b); Indicates the state when it is paused.

The operation of the embodiment of FIG. 1 constructed as above will be described below.

Usually, when the iron is not in use, it is placed upright as shown in FIG. 2(b). At this time, the support 3 is bent by the weight of the magnet 4, and the distance between the magnet 4 and the reed switch 5 increases, and no magnetic flux passes through the reed switch 5, so the reed switch 6 remains off. Therefore, by turning off the reed switch 6, the non-use state can be detected. Next, when ironing is performed, the iron 6 is placed in a horizontal position as shown by the iron 6 in FIG. 1(b). At this time, the iron 6 is moved back and forth and left and right, and since the support 3 has elasticity, the magnet 4 vibrates greatly and repeatedly approaches and moves away from the reed switch 6. As a result, the reed switch 5 repeatedly receives and does not receive the magnetic flux, and thus is repeatedly turned on and off. That is, it is possible to detect that the reed switch 6 is in use by continuously turning on and off. Further, if the iron 6 is left horizontally, the magnet 4 comes to rest in the vicinity of the reed switch 6, so the reed switch 5 remains on. This makes it possible to detect if the device is left in a horizontal position.

As described above, according to the configuration of this embodiment, depending on the on/off state of the reed switch 5, it is possible to detect whether the iron is not in use, in use, or left in a horizontal position.

Therefore, by applying this non-use detection device to irons,
By configuring the heater to automatically turn off the power if it is detected that it is not in use or left horizontally, forgetting to turn it off can be prevented, and a highly safe iron can be constructed. Moreover, since it does not have a mechanical sliding part, if the operating range of the support 3 is designed to be within elastic deformation, a highly reliable iron non-use detection device can be constructed. .

FIG. 3 is a configuration diagram showing still another embodiment of the present invention.

The non-use detection means for the iron shown in FIG. The magnetic flux is detected by a Hall element 24 that outputs a voltage proportional to the magnetic flux density. The figure also shows the iron in a vertical position.

The operation of the embodiment of FIG. 3 constructed as described above will be described below.

When the iron is not in use, that is, when it is placed vertically, the magnet 23 and the Hall element 24 are stationary with a certain distance between them as shown in Figure 3, so a certain voltage is applied according to the magnetic flux density at this time. The Hall element 24 outputs. Moreover, if the iron is left horizontally, the configuration shown in FIG.
The distance of 4 is close and stationary. Since the transverse magnetic flux density increases, the Hall element 24 outputs a higher voltage than when in the vertical state.

Furthermore, when the iron is in use, the magnet 23 vibrates around the fulcrum C in response to horizontal iron movement, as in the embodiment shown in FIG. 1, and the output of the Hall element 24 increases. It fluctuates, becoming higher or lower. Further, the iron may be moved not only horizontally but also vertically, and in this case as well, the magnet 23 vibrates around the fulcrum C and operates in the same manner as described above. As described above, according to this embodiment, depending on the output voltage of the Hall element, if the output voltage is low, it is not used, and if the output voltage is high, it is left in the horizontal position.

If the output is high and the output fluctuates repeatedly, it is possible to detect that the iron is in use based on the output voltage of the Hall element. Further, in this case, it is sensitive not only to horizontal use but also to vertical movement, and since it can be constructed on a printed circuit board, it is possible to construct an excellent non-use detection device for an iron with a small number of parts.

It should be noted that the piano wire in this example is not limited to this, as long as it has elasticity, and it goes without saying that it may be made of elastic resin or the like and may be integrally molded with the magnet. The Hall element can also be replaced with an MR element or a reed switch.

Effects of the Invention As described above, according to the present invention, a highly reliable non-use detection device suitable for iron use can be realized with an extremely simple configuration.
