Description

  The present invention relates to a steam iron used for wrinkle stretching of clothes and the like.

  Conventionally, in this type of steam iron, a thermistor for detecting temperature is attached in the vicinity of a heater and a vaporizing chamber (see, for example, Patent Document 1).

This explains the mounting position of the thermistor that detects the temperature in the temperature control of the iron. When dry, the vicinity of the heater that can quickly sense the heat from the heater is optimal, and no water leaks when used as a steam iron This is because the vicinity of the vaporization chamber is desirable to maintain the temperature.
Japanese Patent Laid-Open No. 58-112599

  However, in such a conventional configuration, the response of the heat sensation of the vaporizing chamber in which the temperature is lowered is still insufficient, and in recent years, there is a problem that water leakage is particularly likely to occur in an iron or the like that has increased the finishing effect with increased steam. .

  The present invention solves the above-described conventional problems, and an object of the present invention is to provide a steam iron that hardly leaks water even when the amount of steam is increased.

  In order to solve the conventional problems, a steam iron according to the present invention includes a base heated by a heater, a vaporization chamber formed in the base, a thermistor for detecting the temperature of the base, and a detection signal of the thermistor. A temperature control means for controlling the temperature of the base is provided, and the thermistor is attached in the vicinity of the heater of the base, and the vaporization chamber is formed so as to surround the thermistor from both sides, and the vaporization temperature decreases during steaming. The temperature of the room can be sensed on both sides and detected more quickly, and the temperature of the base can be controlled to an appropriate temperature to prevent leakage from the ironing surface to the outside.

  The present invention can realize a steam iron that does not leak even when the amount of steam is increased and can efficiently finish wrinkling.

  According to a first aspect of the present invention, there is provided a base heated by a heater, a vaporization chamber formed in the base, a thermistor for detecting the temperature of the base, and a temperature control means for controlling the temperature of the base by a detection signal of the thermistor. The thermistor is mounted in the vicinity of the heater of the base, and the vaporization chamber is formed so as to surround the thermistor from both sides, and the temperature of the vaporization chamber that drops in temperature during steam is quickly detected, and the temperature of the base is determined. Recovery control can be performed to an optimum temperature.

  According to a second aspect of the present invention, in the first aspect, the bottom surface of the portion formed so as to surround the thermistor of the vaporization chamber from both sides is formed lower than the bottom surface of the other portion of the vaporization chamber. Hot water collected in the room gathers on the lowest bottom surface, further cooling the temperature of the vaporization chamber around the thermistor, and the appropriate base temperature control can be quickly performed accordingly.

  According to a third invention, in the first or second invention, at least one of the portions formed so as to surround the thermistor of the vaporizing chamber from both sides is formed at the rearmost portion of the vaporizing chamber, and the iron is made vertical. When the steam is jetted out, the hot water accumulated in the vaporizing chamber collects at the rearmost part, further cooling the vaporizing chamber temperature around the thermistor, and can perform appropriate base temperature control accordingly.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the present embodiment.

(Embodiment 1)
FIG. 1 is a plan view of a base of a steam iron according to the first embodiment of the present invention, and FIG. 2 is a cross-sectional view of a main part of the steam iron.

  1 and 2, reference numeral 1 denotes a base heated by a heater 2, in which a substantially U-shaped heater 2 is embedded. A thermistor 3 for detecting the temperature of the base 1 is attached in the vicinity of the heater 2 and is electrically connected to a temperature control board 5 which is a temperature control means housed in the handle 4. 6 is a vaporizing chamber for generating steam.

  7 is a water tank for storing water to be supplied to the vaporizing chamber 6, and 8 is a steam dial for switching the supply of water from the water tank 7 to the vaporizing chamber 3 and stopping by external operation. Reference numeral 9 denotes a pump device that supplies a large amount of water to the vaporizing chamber 6 to generate increased steam, and its operation button 10 is disposed at the upper part of the water tank 7, and the water suction port 11 is provided with a silicon hose 12. The water tank 7 is configured to extend rearward.

  Here, the vaporization chamber 6 is formed such that a part of the rear is bulged rearward so as to sandwich the thermistor 3 from both sides, and the vaporization chamber surrounding the thermistor 3 is located at the rear of the vaporization chamber 6, And the vaporization chamber bottom face 6a is provided lower than the vaporization chamber bottom face 6b of other portions.

  The portion formed by bulging rearward so as to sandwich the thermistor 3 of the vaporizing chamber 6 from both sides positions the side close to the heater 2 on the outer side of the base 1 almost directly above the heater 2, and 1 has a shape extending rearward from the inward portion. The thermistor 3 is attached to the base 1 on the side opposite to the rearward bulging portion outside the vaporizing chamber 6, that is, inside the thermistor 3 itself.

  Further, the outer wall surface between the portions formed by expanding the thermistor 3 in the vaporizing chamber 6 so as to sandwich the thermistor 3 from both sides is located in contact with or close to the tip of the thermistor 3.

  The operation and operation of the steam iron configured as described above will be described below. First, normal steam ironing will be described. The water in the water tank 7 is supplied to the vaporizing chamber 3 by operating the steam dial 8, and the supplied water sequentially becomes hot water and steam in the vaporizing chamber 6. It is ejected to the outside through a steam hole provided on the hanging surface of 1.

  At this time, the bottom surface of the vaporizing chamber 6 is deprived of heat and the temperature is lowered, and the hot water generated in the vaporizing chamber 6 gathers at a low position on the bottom surface of the vaporizing chamber, that is, the vaporizing chamber bottom surface 6a around the attachment portion of the thermistor 3, Cool the thermistor more effectively. In addition, since both sides of the thermistor 3 are sandwiched between the vaporization chamber 6 wall surfaces, the thermistor 3 can be further cooled, so that the temperature can be detected quickly and the temperature can be controlled to recover to an appropriate temperature. it can. As a result, it becomes difficult for water to leak.

  Further, since the thermistor 3 is attached to the base 1 on the inner side, the rear bulge portion outside the vaporizing chamber 6 can be extended rearward, and the thermistor 3 can be brought close to the inner side. Therefore, the thermistor 3 can more quickly detect the temperature drop of the vaporizing chamber 6.

  Next, a case where ironing is performed in a state where clothes such as a jacket are hung on a hanger will be described. When the operation button 10 of the pump device 9 is operated with the iron standing vertically, a large amount of water is supplied from the suction port 11 to the vaporizing chamber 6 through the pump device 9. The supplied water is instantly vaporized and ejected to the outside, and a large amount of steam brings a texture to clothing.

  At this time, hot water generated in the vaporizing chamber 6 moves to the rear of the vaporizing chamber 6 and gathers. The thermistor 3 is located at the rearmost part of the base 1 and is formed by expanding the rearmost part of the vaporizing chamber 6 so as to surround both sides thereof, so that it is attached to the rear part of the vaporizing chamber 6. The thermistor 3 is quickly cooled, and the temperature can be controlled so as to recover the temperature of the base 1 to an appropriate temperature by acting in the same manner as in the case of normal steam ironing.

  As described above, the steam iron according to the present invention provides a steam iron that hardly leaks water even if the amount of steam is increased, and can be widely applied to steam irons for home use and business use.
