Description

[Detailed Description of the Invention] The present invention relates to a switch mounting device for an electric iron, which is most suitable for portable use, and is particularly intended to insulate the switch from high heat to prevent deterioration, etc., and contribute to making the main body thinner.

For example, electric irons used in various countries both domestically and internationally are equipped with a so-called dual volt switch (voltage changeover switch) that adjusts the voltage applied to the heater to maintain the rated power consumption of the heater, depending on the country of use.

Since this switch is located above the heater in the iron cover fixed to the top of the base, it is constantly exposed to high heat, which may cause the contacts to deteriorate or the switch case to become deformed due to heat. was there.

Also, as mentioned above, since the switch is located above the heater inside the iron cover, it is necessary to set the internal space of the iron cover relatively large, which results in an increase in the thickness of the main body. It became a drawback.

The present invention improves the above-mentioned drawbacks and will be described below with reference to the drawings.

1 is a thin plate-like base with an electric heater 2 fixed on the top surface;
3 is an iron cover fixed to the top surface of the base; 4 is a heat insulation cover consisting of two heat insulation plates 4a and 4b made of heat insulating synthetic resin fixed to the top surface of the iron cover; a partition is provided on the rear inner wall of each heat insulation plate; The walls 5 and 6 are integrally formed, the respective heat insulating plates are fixed vertically, and the rear side bulges downward to form the partition wall 5,
6 forms a heat insulating space 8 inside the bulge 7.

This heat insulating space 8 is located behind the rear wall of the iron cover 3 and is formed below the upper heat insulating plate 4a.

That is, the heat insulating space 8 is arranged within the height dimension H between the base 1 and the upper heat insulating plate 4a.

9, 9 are projecting walls provided on both sides of the rear end of the upper heat insulating plate 4a;
10.10 is a protruding wall provided on both sides of the rear end of the lower heat insulating plate 4b, and 11 is a protruding wall formed by the respective protruding walls 9, 9, 10, and 10 formed by overlapping and fixing the respective heat insulating plates 4a and 4b, which will be described later. The power cord winding groove 12.12 is a winding projection formed on both sides of the winding groove 11 by overlapping and fixing the respective heat insulating plates 4a and 4b, and when winding the power cord, the winding groove 12. It becomes the winding bottom part of No. 11.

Reference numeral 13 denotes a switch that is housed and fixed on one side of the heat insulating space 8 and adjusts the power supply voltage applied to, for example, the electric heater 2 to an appropriate level. The tip of the winding groove 11 is slightly protruded from the bottom of the winding groove 11 .

That is, it is disposed a distance l inward from the winding bottom of the wire connecting the tips of the respective winding protrusions 12.12.

Reference numeral 15 denotes an energization indicator lamp housed and fixed on the other side of the heat insulating space 8, and is illuminated through the display window 16 of the heat insulating cover 4.

17 is a temperature control knob that passes through the heat insulating cover 4 and iron cover 3 and is fixed to the upper end of the adjustment shaft of a thermostat (not shown); 18 is a continuous groove 19 on the inside and a winding groove 20, 20 at a suitable location on the outside. It is a removable bundle in which pieces 21, 21, 22, and 22 are integrally molded and project outward at both ends.When in use, the wings 22 and 22 are attached to the heat insulating cover 4.
The base 1 is fitted inside and combined with the rear side using a suitable opening means 23.23, and the base 1 is inserted into the groove 19 when carried or not in use.
The overall height of the main body is reduced by storing the outer peripheral edge of the main body.

24 is a power cord led out from the rear side wall of the heat insulating cover 4.

Next, the operation will be described. First, in the use state, the wings 22, 22 on one side of the bundle 18 are fitted onto the upper surface of the heat insulating cover 4, and fixed by the locking means 23, 23.

(See Figure 1) The temperature of the base 1 rises as the electric heater 2 is energized, but the partition walls 5 and 6 prevent the base 1 from rising.
Radiation heat from the electric heater 2 side is cut off, thereby preventing the temperature of the switch 13 and the energization indicator lamp 15 from rising.

If the supplied commercial voltage is different, adjust the adjustment knob 14 using a coin or the like to set the power consumption as much as possible to the rated power consumption.

When resting during use, the rear wall and protruding walls 9, 9, 10, and 10 of the bundle 18 are placed on the floor.

In this case, since the adjustment knob 14 is located inside the winding groove 11, it does not touch the floor surface.

When carrying, the outer periphery of the base 1 is stored in the removal groove 19 from the heat insulating cover 4 of the bundle 18, and the power cord 24 is connected to the winding groove 20 of the bundle 18 and the heat insulating cover 4.
Wind it up in the winding groove 11 of.

(See Fig. 4) In this case, the winding portion of the power cord 24 hits the winding protrusion 12, 12 of the winding groove 11 as shown in Fig. 5, and the adjustment knob 14 is located inside the winding projection 12, 12, so the adjustment knob No excessive force is applied to 14.

In addition, in this invention, winding of the power cord was explained with the bundle and the base combined, but it is also possible to wind the power cord with the bundle fixed to the heat insulating cover as shown in Figure 5, but in this case, It is desirable to provide a suitable winding groove on the front side of the cover or the front side of the bundle.

Further, the switch does not necessarily need to adjust the power supply voltage to an appropriate level, but may be used to change the power consumption.

As described above, in this invention, the rear side of the insulation cover bulges downward to form an insulation space with a partition wall, and the switch is housed and fixed within this insulation space, so the switch is isolated from high heat by the partition wall. This prevents deterioration or heat exchange.

Further, since the switch has the rear side of the heat insulating cover fixed in the heat insulating space bulging downward, the overall height of the main body can be reduced, making miniaturization easier.

Further, the partition wall can reinforce the heat insulating cover.

Since the tip of the adjustment knob of the switch is located inside the winding bottom of the power cord winding groove formed on the side wall of the heat insulation cover, the cord does not hit the adjustment knob when the power cord is wound. There is no.
