Abstract

PURPOSE:To enable a drip amount to a vaporizing chamber to be decreased, in the case of low setting the temperature of a base, and the drip amount to be increased, in the case of high setting the temperature, by providing an up- down adjusting area reaching a lower position side from an upper position side in a control needle in the first cam surface corresponding to a temperature adjusting area reaching a low temperature side from a high temperature side provided in the second cam surface. CONSTITUTION:A control needle 23 is provided being able to be associated with the first cam surface 40 of a cam 36 through an operating lever 27 or the like, when the second cam surface 41 sets a temperature adjuster 43 to a low temperature, the control needle 23 is inserted with a play to a drip nozzle 22 decreasing an opening area, while when the second cam surface 41 sets the temperature adjuster 43 to a high temperature, the control needle 23 is extracted from the drip nozzle 22 increasing the opening area. In this way, even when a base 1 is in a low temperature, steam can be injected with no hot water jetted, while in case of the base 1 being in a high temperature, a sufficient amount of steam is jetted even to a fiber with a wrinkle not easily ironed out, enabling the wrinkle to be surely smoothed.

Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to a steam iron.

(Prior Art) In general, a steam iron has a vaporizing chamber formed in its base, and water is dripped into the vaporizing chamber from a water tank through a drip nozzle equipped with a valve rod, and the steam generated here is transferred to the vaporizing chamber. The steam is ejected from the connected base's steam outlet. During use, after adjusting the temperature of the base using a temperature controller, a push button is pressed to open a dripping nozzle using a valve lever to drip water into the vaporization chamber and generate steam.

(Problem to be Solved by the Invention) It is desirable for a steam iron to eject steam according to the temperature of the fibers, but in the above conventional technology, the amount of water dripping from the dripping nozzle is constant regardless of the temperature of the base. Therefore, when the concentration of the base was set at a low temperature, the water dropped into the vaporization chamber could not be completely vaporized and became hot and dangerously ejected from the steam outlet. Also the temperature of the cotton base.

When using a high-temperature fiber such as hemp, there was insufficient steam and it was not possible to obtain sufficient wrinkle smoothing.

Therefore, the present invention provides a steam iron that can reduce the amount of dripping into the vaporization chamber when the base temperature is set low, and increase the amount of dripping into the vaporization chamber when the base temperature is set high. The purpose is to provide.

This is a steam passageway connected to the

Next, the operation of the above structure will be explained.

When the operating body 31 is rotated via the operating knob 38 and the operating knob 38 is aligned with the position of the steam iron hair J on the display plate 39, the cam 36 is also rotated in accordance with the rotation. first and second cam surfaces 40,41 respectively
Interlocking rod 29 by lower side 40B and low humidity side 41B,
The adjustment rod 42 is displaced upward. The concentration adjustment B43 is set by the adjustment rod 42 to a relatively low temperature (approximately 155° C.) at which the base 1 can generate steam.

In addition, as the interlocking rod 29 moves upward, the operation rod 27 and the operation plate 2
6 is also displaced upward, and the control rod 2 with υ''-needle 23 is
4 is also displaced upward. At this time, the control needle 23 is stopped at a position where it cannot be removed from the dripping nozzle 22. That is, the opening area of the drip nozzle 22 is set to be small by the ill m needle 23.

Further, the adjusting rod 34 is restrained by a regulating plate 48, and the opening/closing port 32 is kept closed by the opening/closing valve 33. The temperature of the base 1 gradually rises as the heater 2 is energized, and when the temperature reaches m degrees at which steam can be generated, the bimetal 46 senses this and reverses itself. This reversal of the bimetal 46 causes the response rod 47 and the regulation plate 48 to rise integrally against the spring 51.
The restriction of the adjustment rod 34 by the IJ plate 48 is released, and as a result, the opening/closing rod 34 is raised by the biasing force of the spring 35, and the opening/closing opening 32 is opened. Therefore, the water in the water tank 10 flows through the outflow hole 18, the water passage 20. The liquid is sequentially dripped into the vaporization chamber 3 through the fmllJJ port 32 and the dripping nozzle 22. Then, the vaporized steam passes through the steam passage 52 and the steam outlet 4 and is ejected out of the base 1 from the steam outlet 53. When the spray surface temperature is set to a relatively low temperature in this way, the control needle 23 is inserted into the drip nozzle 22 at T1, and therefore the number of water supply personnel is limited.
Since the appropriate amount of water m that can be vaporized drops even at a low surface temperature, hot water does not spout out from the steam outlet 53.

Next, when the operation knob 38 is set to the "steam iron hemp" position, the cam 36 also rotates integrally, and the high temperature flI41 of the upper side 40A of the first cam surface 40 and the second cam surface 41
A causes the interlocking rod 29 and the adjusting rod 42 to move upward. The temperature 11111 vessel 43 is set to a relatively high hot water temperature (approximately 190° C.) at which the base 1 can generate steam. Further, with the upward displacement of the interlocking rod 29, the operating rod 21 and the operating plate 26 are further upwardly displaced, and the control rod 24 provided with the 1iJtll needle 23 is also upwardly displaced, and the control needle 23 is connected to the drip nozzle 2.
2, the opening area of the dripping nozzle 22 increases, and the amount of water dripping into the vaporization chamber 3 increases. At this time, head 1
Since the temperature is set at a high temperature (approximately 190 degrees Celsius), the vaporization capacity is also increased, and all of the dripped water is vaporized, and as in the above case, more water is produced without spouting out hot water from the steam outlet 53. Can generate steam.

Furthermore, when the operation knob 38 is set to the "dry iron" position, the cam 36 rotates in the opposite direction, and the interlocking rod 29 is operated by a portion (not shown) that protrudes downward from the lower part of the first cam vR4O. The rod 27, the operation plate 26, and the adjustment rod 34 are pressed downward, and as a result, the on-off valve 34 normally closes the on-off port 32 and stops the supply of water to the vaporization chamber 3.

Further, the temperature regulator 43 is set to a predetermined temperature via the interlocking piece 44 due to the height difference of the second cam surface 41.

In this way, in the above-mentioned embodiment, the first cam surface 40 of the cam 36 is connected to the operating rod 27 etc. in the above-mentioned 11. IJ'
The Ill needle 23 is interlockably provided, and when the second cam surface 41 sets the temperature regulator 43 to a low temperature, the control needle 23 is inserted loosely into the dripping nozzle 22 to reduce the iorM angle, and the second cam surface 41 The temperature of cam 1Ii41 is m Immediate answer 43
When the temperature of the base 1 is set to a high temperature, the control needle 23 is pumped out from the dripping nozzle 22 to increase the opening area. When the temperature in step 1 is high, sufficient steam is ejected even from fibers that are difficult to remove wrinkles, and the wrinkles can be reliably removed.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and any modifications can be made, such as forming the sintering needle into a tapered shape and continuously changing the opening area of the dripping nozzle. .

[Effect of the invention 1] As described above, the present invention provides a control needle for the dripping nozzle in response to the base temperature, so that when the base temperature is set to a low temperature, the dripping m is reduced and the spraying is performed. It is possible to provide a steam iron that can prevent hot water from spewing out from the outlet and can spout sufficient steam when the base concentration is set at a high temperature.
