ムアイロンに関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a steam iron in which the supply of water is stopped unless the base temperature reaches a value suitable for vaporizing water.
従来例の構成とその問題点

腐食の原因となることがあつた。Conventional configurations and their problems Currently, the mainstream steam generation method for steam irons is the so-called drip type, in which the vaporizing chamber and the steam passage are directly connected, and the steam generated in the vaporizing chamber is directly guided to the steam outlet on the base surface. However, with this drip-type steam iron, if water is supplied to the vaporizing chamber when the base temperature has not reached a value suitable for vaporizing water, the dripping water will not turn into steam and sometimes hot water will flow out of the steam outlet. gushing,
After use, water remained in the vaporization chamber, causing corrosion of the vaporization chamber and base.
そこで、この欠点を解決するために第１図のよ
うなスチームアイロンが開発されている。 In order to solve this problem, a steam iron as shown in FIG. 1 has been developed.

されている。 In the figure, a heating element 2 is embedded in a base 1, and a vaporization chamber 4 and a steam ejection hole 5 are formed in communication with each other via a steam passage 3. A nozzle 7 is provided at the bottom of the water tank 6, and a nozzle hole 7'
Water drips into the vaporization chamber 4 through the evaporation chamber 4. Further, the nozzle 7 is configured so that an opening/closing rod 9 can be moved up and down by operating a steam button 8 to open and close the nozzle hole 7'. This opening/closing rod 9 is always urged upward by a spring 10.
Reference numeral 11 denotes an operating shaft, a permanent magnet 12 is fixed to the lower end, and the upper end is connected to the opening/closing rod 9 via a lever 11'. Reference numeral 13 denotes a heat sensitive body made of ferrite, Ni-Cu type, Ni-Fe type alloy, etc., with the Curie point set at a predetermined temperature, and is fixed to the base so that the heat of the base 1 is received at a position facing the permanent magnet 12. has been done.
８′はスチームボタン８と開閉桿９とを連係す

気吸引力が作用し、作動軸１１と連結した開閉桿
９はスプリング１０の反発力に抗してノズル７に
押圧されノズル孔７′は閉じた状態になる。 8' is a spring that links the steam button 8 and the opening/closing rod 9. In the above configuration, when the steam button 8 is operated to raise the opening/closing rod 9,
If the temperature of the base 1 is low and has not reached a value suitable for water vaporization, the heat sensitive body 13 is a magnetic material at a temperature below the Curie point, so a magnetic attraction force acts between it and the permanent magnet 12, and the temperature is activated. The opening/closing rod 9 connected to the shaft 11 is pressed against the nozzle 7 against the repulsive force of the spring 10, and the nozzle hole 7' is closed.
次に、ベース１の温度が十分上昇して気化に適

た状態になる。これにより、水タンク６内の水は
気化室４に供給され、スチームとなつて気化室４
と連通したスチーム噴出孔５から噴出される。 Next, when the temperature of the base 1 rises sufficiently to a value suitable for vaporization and the temperature of the heat sensitive body 13 exceeds the Curie point, the heat sensitive body 13 becomes a permanent magnet 12 that does not lose its magnetism.
The magnetic attraction force between the permanent magnet 12 and the operating shaft 1 ceases to act, and the repulsive force of the spring 10 causes the permanent magnet 12 and the operating shaft 1 to
1 and the opening/closing rod 9 rise, and the nozzle hole 7' becomes open. As a result, the water in the water tank 6 is supplied to the vaporization chamber 4 and becomes steam.
The steam is ejected from the steam ejection hole 5 that communicates with the steam.
以上のように、永久磁石１２と感熱体１３とを

けの磁気吸引力が得られないということが起こ
る。 As described above, the permanent magnet 12 and the heat sensitive body 13 are placed opposite each other, and the opening/closing rod 9 is operated by the change in the magnetic force acting between them, and unless the temperature of the base 1 reaches a value suitable for vaporizing water, water is supply is now being stopped. However, in the above-mentioned conventional configuration, the permanent magnet 12 and the heat sensitive body 13 are simply opposed to each other, so the magnetic attraction force that acts between them decreases greatly as the distance between them increases.For example, when the two are completely attracted (the distance is 0) ), even if the opening/closing rod 9 can obtain a magnetic attraction force sufficient to press the nozzle 7,
If the distance is 1 mm, it will not be possible to obtain a magnetic attraction force sufficient to overcome the repulsive force of the spring 10, the frictional force between the opening/closing rod 9, the operating shaft 11, and other parts.

実用性に乏しいものであつた。 Therefore, as a practical matter, in order to operate reliably with the above configuration, the maximum distance (stroke) between the permanent magnet 12 and the heat sensitive body 13 must be made considerably small, or
Either make the permanent magnet 12 extremely large, or
The second material had to be made of a special and expensive material, and in any case, it was impractical in terms of reliability and cost.

Even if the distance between the permanent magnet and the heat sensitive body increases, the magnetic attraction force acting between the two does not decrease significantly.

る。DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 2 and 3.
This will be explained with reference to the figures. In the figure, the same parts as those in the conventional example are given the same numbers and their explanations are omitted.
図において、軸方向に着磁された永久磁石１

てある。その他の構成は従来例と同様である。 In the figure, a permanent magnet 1 magnetized in the axial direction
A heat sensitive element 13 located at the lower part of the base 2' and having a Curie point set at a predetermined temperature is fixed to the base 1 so as to receive the heat of the base 1. Reference numeral 14 denotes a magnetic yoke made of a magnetic material, which is fixed in contact with the heat sensitive element 13 and surrounding the permanent magnet 12' with a gap therebetween. Further, a guide body 15 made of a non-magnetic material such as a resin tube is attached to the inner surface of the magnetic yoke 14 so as to be interposed between it and the permanent magnet 12'. The other configurations are the same as the conventional example.

孔７′は閉じた状態になる。 With this configuration, when the temperature of the base 1 is low and the temperature of the heat sensitive element 13 is below the Curie point, a magnetic circuit as shown by arrow a is formed, and the permanent magnet 12'
A magnetic attraction force acts in the direction of arrow b in FIG. 3.
At the same time, the opening/closing rod 9 connected to the actuating shaft 11 also moves in the direction of arrow b', and is pressed by the nozzle 7 to close the nozzle hole 7'.
次に、ベース１の温度が上昇し感熱体１３の温

なる。 Next, when the temperature of the base 1 rises and the temperature of the heat sensitive element 13 exceeds the Curie point, the heat sensitive body 13 becomes a non-magnetic material and no vertical magnetic attraction force acts on the permanent magnet 12'. Due to the repulsive force of the spring 10, the permanent magnet 12', the operating shaft 11, and the opening/closing rod 9 are raised, and the nozzle hole 7' is opened.
なお、ガイド体１５は、永久磁石１２′と磁気
ヨーク１４との間に常時作用する水平方向の磁気
吸引力によつて両者が接触して上下方向の動きが
悪くなるのを防止している。 Note that the guide body 15 prevents the permanent magnet 12' and the magnetic yoke 14 from coming into contact with each other due to the horizontal magnetic attraction force constantly acting between them, thereby preventing their vertical movement from becoming worse.
さて、本実施例における永久磁石１２′と感熱
体１３との間に作用する磁気吸引力の距離による
減衰を従来例におけるものと比較すると、第４図

い（永久磁石は同一形状）。 Now, if we compare the attenuation of the magnetic attraction force acting between the permanent magnet 12' and the heat sensitive body 13 with the distance in the present embodiment with that in the conventional example, there is a relationship as shown in FIG. 4, and it is clear that this embodiment In the example, the attenuation rate of magnetic attraction force due to distance is smaller (permanent magnets have the same shape).
なお、本実施例のガイド体１５は磁気ヨーク１

でもない。 Note that the guide body 15 of this embodiment is similar to the magnetic yoke 1.
4, it goes without saying that the same effect can be obtained even if the guide body 16 is fixed to the outer periphery of the permanent magnet 12' as shown in FIG.
