A locking portion 9b is formed which can protrude outward through the hole a.

Reference numeral 10 denotes a cord case made of transparent resin, which is fixed to the heat-resistant plate 6 on the rear side of the main body 1 via a case fixing member 11, and houses a cord winding body 12 inside. The cord winding body 12 has a rotary winding drum 12a, which is an axis of rotation, supported by the heat-resistant plate 6 and the case fixing body 11, and
A plurality of cord guide plates A12 perpendicular to the axis of 2a
b, B12c are fixedly attached or integrally formed with a gap sufficient to form a groove 14 for housing the power cord 13. The power cords 13 are stacked and wound up between the plurality of cord guide plates A12b and B12c. Further, one end of the power cord 13 is always exposed to the outside through a cord outlet 15 formed in the cord case 10 and the fixed body 11, respectively, and a plug device 16 larger than the cord outlet 15 is connected to the outermost end. has been done.

Reference numeral 20 denotes a heat radiation path for dissipating the heat of the cord 13, which communicates with the cord outlet 15 through the outer circumference of the cord winding body 12 from long holes 18, which will be described later, so that the heat released from the cord 13 is communicated with the cord outlet 15. code 1 again
It is formed so that it will not go back to 3.

Reference numeral 17 denotes a sloped locking protrusion formed on the inner guide plate A12b of the cord guide plates, and the slope is formed to be higher in the direction of rotation of the rotary winding drum 12a. There is. A plurality of elongated holes 18 facing in the radial direction are bored in the cord guide plate B12c located on one outer side.

The cord winding body 12 is always elastically biased in the cord winding direction, the locking member 9 is always biased toward the locking protrusion 17, and the winding operation lever 8 is moved by a spring 19. Therefore, it is always urged outward.

In the cord winding device having such a configuration, the cord winding body 12 is almost covered by the cord case 10, so even if the main body 1 is moved during use, the cord winding body 12 will not get caught on clothing, etc. Therefore, there is no risk of damage, and no dust or the like will adhere to the cord winding body 12, its rotating shaft, or the wound cord 13, and the rotation of the cord winding body 12 will last for a long time. It crosses smoothly and is visually beautiful. Furthermore, as shown by the small arrows in the drawing, the heat of the cord winding body 12 is radiated from the groove 14 through the long holes 18, and then escapes to the outside air through the cord outlet 15 through the heat radiation path 20 in the cord case 10. Therefore, even though the cord winding body 12 is covered with the cord case 10, the cord 13 can be prevented from becoming hot. Furthermore, since the heat radiation opening of the heat radiation path 20 is also used as the cord outlet 15 formed on the upper part of the cord case 10 for drawing out the cord 13, the rising high temperature atmosphere is quickly exhausted, and the heat radiation path 20
There is no need to provide a separate opening for heat radiation.
In addition, the stored state of the cord 13 can be confirmed through the transparent cord case 10 and the long hole 18, so that even if something is twisted during the winding operation, it can be noticed immediately, and the Damage can be avoided.

Furthermore, if the cord 13 pulled out from the cord outlet 15 is hooked into the cord storage groove 8c, the iron can be used safely without worrying about accidentally operating the winding operation lever 8, and can be stored after use. It is very convenient to be able to compactly organize the code 13 even at times.

(f) Effects of the invention According to the invention, since the cord winding body is almost covered and stored in the cord case, there is no risk of damage to the cord winding body even if the body is moved while the iron is being used. Moreover, the rotation is smooth over a long period of time and is visually beautiful. Furthermore, since the cord case is made of transparent resin, the inside can be checked through the cord case, and the winding state of the stacked cords can be checked through the elongated hole, so there is no possibility that the cord will be twisted or unwound. The advantage is that if it is damaged, it will be immediately noticed and no major damage will be caused. In addition, a cord outlet is provided at the top of the cord case, and a heat radiation path is provided from the long hole of the cord winding body to the cord outlet, and the heat radiation hole of the heat radiation path is also used as the cord outlet. Even though the handle is covered with a cord case, the heat is quickly transferred to the outside air through the heat radiation path until the cord wound around the cord winding body reaches a high temperature due to the influence of the appliance or its own heat generation. There is no need to provide a separate heat dissipation port.
