Description

[Detailed explanation of the idea] This invention relates to electric curtains.

There was a fear that when the electric curtains were opened and heated together, they would overheat and burn the electric curtains.

The present invention has been devised in view of these points, and the object is to provide an electric curtain that cannot be energized unless it is closed.

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a side view of an electric curtain according to the present invention. 1 shows the curtain fabric used for electric curtains. Reference numeral 2 denotes a heat-generating resistance wire sewn into the interior of the curtain fabric 1, which is wound twice through a polyamide resin or the like whose impedance changes depending on the temperature. In addition to controlling the temperature, when it overheats, the polyamide resin melts and the heating wire comes into contact with the shorting wire, turning off the safety circuit included in the controller. 3 is a controller that controls the intensity of the temperature of the electric curtain. 4 is a plug that is inserted into a commercial power outlet of 100 V/50, 60 Hz, and 5 and 6 are plugs and other connectors that are connected to the heating wire 9 and short circuit wire 10 sewn into the curtain fabric 1 of the electric curtain. There is. These two plugs connect or disconnect the points 12 and 12' of the heating resistance wire 2, and are installed at the top of both ends of the electric curtain, and are located at corresponding positions when the electric curtain is expanded. 8 and an outlet 8' which is one of the connectors provided on the controller 3. By connecting and inserting both connectors, which are outlets at both ends, the controller 3 is constructed, and the electric blanket can be energized.

FIG. 2 is a schematic sectional view showing details of the outlet 8, which is the other connector, and the plug 5, which is the connector. 11 indicates a short circuit line.

FIG. 3 is a block diagram of the electric curtain of the present invention, and the numerals are as previously explained.

Next, the operation will be explained. When the curtain is expanded and the plugs 5, 6 at both ends are connected to the connectors 8, 8', the control circuit 3 is constructed and the electric curtain is energized. The controller 3 also includes a regulator that controls the intensity of the temperature. If you open the electric curtains and pull them to one end, and the electric curtains are stacked together, please refer to step 2 above.
Since one or both of the two connectors, plugs 5 and 6, are disconnected, the controller of the electric blanket is open and not configured, and therefore cannot be energized.

By configuring as described above, when the electric curtain is opened and the fabrics overlap, electricity cannot be applied, so it is possible to prevent overheating due to the overlap of the fabrics.
