る。The structure of the electric blanket of the present invention for achieving the above object is such that a heating wire for warming a sleeping human body is arranged in a meandering shape in a blanket main body, and two electrode wires are provided. A heat-sensitive wire in which a resin whose impedance changes depending on temperature is arranged is arranged in parallel to the meandering heat-generating wire, and a part of this heat-sensitive wire is arranged from the portion where the heat-generating wire is arranged to the blanket body.

For example, it is possible to use a bag weaving means that has been conventionally used, a means that sew a non-woven fabric with a needle punch, and a method that sew other portions to each other while leaving a portion through which a heating wire and a heat-sensitive wire are inserted. . In the present invention, the bag-weaving means that the blanket body is woven by connecting two blanket materials to each other so as to be integrated, and weft threads of each blanket material are entwined with the other warp thread to connect (bonding) each other. ).

Therefore, the heating wire, the heat-sensitive wire, and the like may be opened for insertion, and after wiring, the peripheral portion of the blanket body may be sewn by trimming. The wires are arranged in a meandering shape by inserting a heating wire and / or a heat-sensitive wire into the wire connecting portion and inserting a wire exiting the wire connecting portion into a next predetermined wire connecting portion. It is a thing. And when disposing the heat sensitive wire away from the heat generating wire, it may be arranged so as to pass through the outside of the positioning portion.

度以下で通電が停止される。The heat-sensitive wire used in the present invention is not particularly limited, and those conventionally used for electric blankets can be used as they are. For example, a polyamide resin whose impedance value decreases as the temperature rises may be used as the heat sensitive body. For example, when a polyamide resin is used for the heat sensitive body, when the temperature of the portion where the heating wire is arranged rises, the impedance of this portion decreases, but the blanket temperature of the portion where the heating wire is not arranged in use ( When the blanket ambient temperature) rises, the impedance of the heat-sensitive wire in this portion also decreases, so the temperature at which the impedance value corresponding to the set temperature is reached becomes low, and the energization is stopped below the set temperature.

えを防止することができる。On the other hand, when the blanket temperature (blanket ambient temperature) in the portion where the heating wire is not arranged is lowered, that is, when the room temperature is lowered, the impedance of this portion rises,
Since the decrease of the synthetic impedance is suppressed, the temperature reaching the impedance value corresponding to the set temperature becomes high,
If the temperature does not reach the set temperature, the power supply will not stop. Therefore, even if the set temperature is not particularly raised, the amount of heat generation increases, and it is possible to prevent cooling.

It can also be used as a sensor to prevent the fuse from being blown, making the wiring inside the blanket simpler.
