Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an iron for smoothing wrinkles on clothes and the like.

[0002]

2. Description of the Related Art Conventionally, this type of iron has been constructed as shown in FIG. The configuration will be described below.

As shown in the figure, a vaporization chamber 42 is formed in a base 41 having a heater 40, a water tank 43 is arranged above the base 41, and water in the water tank 43 is supplied to the vaporization chamber 42 through a nozzle 44. I am trying to do it. The opening / closing rod 45 for opening / closing the small hole of the nozzle 44 is moved up and down by operating the steam button 46 to control the supply of water to the vaporization chamber 42.

A spray nozzle 47 provided above the front of the water tank 43 atomizes the water in the water tank 43 to atomize it. A pump device 48 for supplying water to the spray nozzle 47 is provided with a spray button 49. It works by operation. By operating the spray button 49 up and down, the water in the water tank 43 is sucked, and by sending it to the spray nozzle 47, mist can be sprayed.

[0005]

However, the conventional structure as described above has the following problems.
That is, when wrinkles are stretched on clothes or the like, the steam button 46 is operated so that the wrinkles are easily stretched and ironing is performed while ejecting steam, but when there are many wrinkles,
If the fabric is a fiber such as cotton or linen that does not easily wrinkle,
Ironing is generally performed after applying a mist to give a large amount of moisture to the fibers.

However, in the above structure, since the spray nozzle 47 is located above the front part of the water tank 43, the sprayed mist spreads greatly on the fibers, and the mist is applied to the part where the mist is not needed. , As a result, the area to be ironed to dry the mist increases,
The work efficiency was very poor.

Further, in the case of a fog having a particle diameter of 20 to 30 μm, which is generally considered to have high water absorption of natural fibers such as cotton and hemp, the fog is very fine and it is difficult for the operator to see the spray state. As a result, spraying is repeated more than necessary, and in addition to the increase in drying work as described above, there is the problem that the water consumption increases and the number of times water is supplied to the water tank increases, resulting in poor usability. It was

Further, when the sprayed mist is fine, the sprayed area is not clearly visible, and it is easy to forget to iron it, and the water content of the mist remains on the clothes, causing new wrinkles. Was becoming.

The present invention solves the above-mentioned problems of the prior art by improving the work efficiency of ironing by preventing mist from being sprayed on an extra portion, and by stably generating a good mist to improve the finishability. The first purpose is to improve

A second object is to improve workability by making it possible to confirm the spray state during work.

[0011]

In order to achieve the first object, the present invention guides water in a water tank and steam generated in a vaporization chamber to a mixing chamber, and the flow velocity of the steam causes the inside of the mixing chamber to move. The water from the water tank is granulated, and the water and steam in the mixing chamber are guided to the hanging surface side of the base by a jet nozzle, and the mixing chamber is at least a part thereof.
Is provided so as to be exposed to the outside of the iron body .

As a result, the spray can be obtained from the hanging surface of the base, and as in the ordinary ironing with steam, it is possible to finish only in the range slipped on the fiber, the ironing work can be efficiently performed, and the inside of the mixing chamber can be efficiently processed. Since the temperature rise is suppressed by being cooled by the outside air and the evaporation of the spray water fed into the mixing chamber is suppressed, a good mist can be stably sprayed.

In order to achieve the second object,
The mixing chamber is made of a transparent or translucent material. This makes it possible to see the granulation of water inside the mixing chamber,
Since the state of fog generation can be checked during the work, the work can be performed with peace of mind and the usability is improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 to 5, the iron body 10 includes a base 13 having a vaporization chamber 12 covered with a lid 11 and a heater 14 for heating the base 13.
Depending on the temperature detection means 15 such as a thermistor for detecting the temperature of the base 13, the temperature setting means 16 for arbitrarily setting the hanging surface temperature of the base 13, the output of the temperature detection means 15 and the input of the temperature setting means 16. Temperature control means 1 including a plurality of electronic components for controlling the temperature of the base 13
7, a water tank 18 for storing water, and a water channel 19 for sending the water in the water tank 18 to the vaporization chamber 12 and the like.

The temperature control means 17 has a microcomputer, and when the temperature setting means 16 is operated to set the temperature, the temperature of the base 13 is detected by the output signal of the temperature detection means 15, and the temperature is set to the set temperature. If the temperature is low, a switch (not shown) is turned on to energize the heater 14 and heating is performed until the temperature reaches the set temperature.

On the contrary, for the set temperature, the base 1
When the temperature of 3 is high, the switch is turned off, the heater 14 is not energized, and the temperature of the base 13 is controlled by natural cooling until the set temperature is reached.

The water tank 18 has a nozzle 20 for supplying water to the water passage 19 and an opening / closing rod 2 for opening / closing the nozzle 20.
1 and a mist button 22 for operating the opening / closing rod 21.

The water passage 19 is formed by sandwiching the packing 24 on the support plate 23 provided above the lid body 11 and fastening the water guide body 25 to guide the water in the water tank 18 to the vaporization chamber 12. The first water conduit 26 and the water tank 18
A support plate provided above the lid body 11 having a second water conduit 28 for guiding the water therein to the mixing chamber 27 and a steam passage 29 for guiding the steam generated in the vaporization chamber 12 to the mixing chamber 27. Two
3 is integrated on the top.

The water guiding body 25 is formed of a transparent or translucent resin, and the mixing chamber 27 integrally formed with the water guiding body 25 is also transparent or translucent so that the internal condition can be visually recognized from the outside. Then, the mixing chamber 27 is connected to the second water conduit 2
8 is projected upward in a dome shape, and its upper surface is projected from a base cover 30 that covers the upper surface side of the base 13 and is exposed to the outside of the iron body 10.

Reference numeral 31 denotes two ejection nozzles, which are arranged from the inside of the mixing chamber 27 toward the groove-shaped diffusing portion 32 which is recessed in the hanging surface of the base 13, and which has a hollow internal tube structure. They are provided so as to face each other at a predetermined interval between the jet ports 33 provided in the lower portion, and are integrally formed on the support plate 23 together with the water guide body 25.

To explain the operation of the above structure, in order to perform ironing, the power is turned on and the temperature setting means 16 is used.
When the base 13 is set to an arbitrary temperature by operating, the temperature control means 17 outputs a signal in response to the output of the temperature detection means 15, the heater 14 is energized, and the base 13 reaches the set temperature. The temperature rises and is controlled to maintain the set temperature, and ironing can be started after the set temperature is reached. At this time, ironing can be performed in a "dry" state in which water is not supplied to the vaporizing chamber.

When ironing is performed by spraying a mist on fibers such as cotton and hemp that do not easily grow in wrinkles or fibers that have particularly wrinkles, the mist button 22 is operated to move the opening / closing rod 21 upward. The nozzle 20 is pulled up and the water in the water tank 18 is supplied to the water channel 19 by opening the nozzle 20. The water supplied into the water channel 19 is branched into two systems, a first water channel 26 communicating with the vaporization chamber 12 and a second water channel 28 communicating with the mixing chamber 27.

The water from the first water conduit 26 evaporates in the vaporizing chamber 12 and is supplied as steam to the mixing chamber 27 through the steam passage 29. On the other hand, the water from the second water conduit 28 is directly sent to the mixing chamber 27, but becomes fine particles due to the flow velocity of the steam ejected from the steam passage 29. At this time, since the mixing chamber 27 projects upward from the second water conduit 28 in a dome shape, the flow velocity of the steam introduced from the steam passage 29 to the mixing chamber 27 is accelerated, and the mixing chamber 27 is discharged from the second water conduit 28. The water introduced into the mixing chamber 27 can be made into uniform particles.

As described above, the inside of the mixing chamber 27 is in a state in which steam and granular water are mixed, and the gas and liquid are mixed with each other.
It is ejected to the outside through the two ejection nozzles 31 in the phase state. At this time, as described above, since the ejection ports 33 provided in the lower portion of the ejection nozzle 31 are configured to face each other with a predetermined interval, the ejected steam and the granular water collide violently in the air, The water is further crushed into fine mist and becomes mist, and diffuses as mist-containing steam into the diffusing part 32 provided in the hanging surface of the base 13 and recessed in a groove shape.

Therefore, when the mist button 22 is operated to set the "mist", the spray is obtained only in the diffusing portion 32 on the lower surface of the base 13, so that the area slid on the fibers is the same as the usual ironing with steam. Is hydrated,
The ironing work can be done efficiently.

In other words, it is possible to prevent the needless ironing for the drying, the generation of new wrinkles due to insufficient drying and insufficient drying because the mist is applied to the unnecessary portions. Further, the water in the water tank 18 is not wasted, the number of times of water injection can be reduced, and ironing can be performed more efficiently.

Further, by constructing the water passage 19 in the support member 23 arranged on the base 13 as described above, a water flow passage from the first water passage 26 to the vaporization chamber 12 and a second water passage 28.
Since it can be integrally formed so that there is no step or connection portion in the flowing water passage from the mixing chamber 27 to the mixing chamber 27, an almost constant amount of water can be obtained without obstructing the flow of water.

Therefore, the amounts of water and steam supplied into the mixing chamber 27 can always be stably obtained,
The atomization of water in the mixing chamber 27 becomes uniform, and the jet nozzle 31
Both the amount of spray and the particle size are stable, and the finish by ironing is good.

Further, the upper surface of the mixing chamber 27 provided in the water guiding body 25 made of transparent or translucent resin is placed on the iron body 1
With the configuration of 0 exposed to the outside, the upper surface of the mixing chamber 27 is cooled by the outside air, so that the internal temperature can be suppressed low.

Therefore, the water supplied from the second water conduit 28 to the mixing chamber 27 is suppressed from evaporating in the mixing chamber 27, the amount of spray sprayed from the spray nozzle 31 is stabilized, and ironing is performed. The finishability is improved.

Also, the mixing chamber 27 can be checked from the outside.
By having the above, it is possible to visually check the state of water granulation by the steam inside the mixing chamber 27, and to visually confirm the state of fog generation during work, so that ironing can be performed with confidence and usability is improved. is there.
