DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spray iron for removing wrinkles of clothes and the like used in ordinary households.

[0002]

2. Description of the Related Art To reduce wrinkles of clothes, etc., use "temperature".
The three elements of "moisture" and "pressure" are indispensable, and steam irons satisfying these elements are now widely used in ordinary households. However, in the case of vegetable fibers, for example, cotton and hemp, steam alone cannot provide a sufficient amount of water to extend wrinkles, and it is difficult to extend wrinkles. For this reason, in recent years, spray irons capable of giving a large amount of water to fibers have become widespread. As this type of spray iron, a configuration as shown in FIG. 8 is generally used. Hereinafter, the configuration will be described.

[0003] Reference numeral 101 denotes an iron base for extending wrinkles of clothes, and reference numeral 102 denotes a handle mounted on the upper surface of the iron base 101. The handle 102 is a water tank 103
It has. 104 is a cylinder having a check valve 105 at the bottom and a fountain port 106. Reference numeral 107 denotes a nozzle that penetrates the front wall of the handle 102 and protrudes outward, and is connected to the fountain port 106 through a water pipe 108. A piston 109 is slidably inserted into the cylinder 104 so as to be vertically slidable. An upper end of the piston 109 projects outside the cylinder 104, and a receiving plate 110 fixed to the upper end and the cylinder 1
It is constantly urged to rise by the spring 111 contracted between the parts. 112 is a through hole 113 at the top of the handle 102
The lower surface of the push button is freely engaged with the upper end of the piston 109.

With the above configuration, the operation is as follows. When the user pushes the push button 112 with the thumb while holding the handle 102, the piston 109 moves against the cylinder 111 against the spring 111.
4 down. When the piston 109 descends in the cylinder 104, the water in the cylinder 104 passes from the nozzle 107 through the fountain port 106 and the water pipe 108 as the piston 109 descends because the check valve 105 is closed.
02 is sprayed on clothing performing ironing ahead.

Next, when the pressing force on the push button 112 is removed, the piston 109 moves up in the cylinder 104 by the spring 111. As a result, the pressure in the cylinder 104 becomes more negative than in the water tank 103. Therefore, the water in the water tank 103 is sucked into the cylinder 104 while opening the check valve 105. For this reason, cylinder 10
4 is filled with water, and the check valve 105 is closed again.

When the push button 112 is pressed again in this state, water in the cylinder 104 is sprayed from the nozzle 107 in the same manner as described above. The cylinder 104 and the piston 109 perform a pumping operation by repeatedly applying and releasing the pressing force to the push button 112 in this manner, and spray the water in the water tank 103.

[0007]

In the above-mentioned conventional structure, the particle size of the mist sprayed from the nozzle 107 is 100 μm.
These are very large. For this reason, water droplets are likely to be formed on the sprayed clothing surface, which causes stains after the ironing operation.

[0008] The present invention is intended to solve the problems of such a conventional structure, and can perform uniform and uniform spraying, and is suitable for vegetable fibers such as cotton and hemp. It is an object of the present invention to provide a spray iron that can achieve a finished state.

[0009]

SUMMARY OF THE INVENTION In order to solve this problem, the present invention provides a method of finely distributing water by using steam jet power.
The iron is atomized and can be diffused and ejected from a spray nozzle provided in the iron body.

Reference numeral 4 denotes at least one lower surface injection nozzle which communicates with the vaporization chamber 3 and has an opening at the tip end near the concave recess 15 on the bottom surface of the iron base 1.

The operation of the embodiment will be described below. First, when the operator presses the steam button 9 to release the latch mechanism, the opening / closing shaft 7 is stopped upward by the urging force of the opening / closing spring 8, and the water tank outlet passage 6 is opened. Then, the water in the water tank 4 is dropped into the vaporization chamber 3 via the water tank outlet passage 6, the steam check valve 10, and the main water passage 11 due to the head difference. The water dropped into the vaporization chamber 3 is supplied to the steam passage 1
3 and branch to the headrace channel 12. The water branched into the steam passage 13 becomes steam. Then, due to a phase change when the water turns into steam, the internal pressures of the vaporization chamber 3 and the main water passage 11 rise temporarily, and the steam check valve 10 closes. Then, the steam generated in the vaporization chamber 3 blows out from the steam passage 13 to the lower surface spray nozzle 14. At this time, the water in the branch water conduit 12 is not sufficiently vaporized in order to short-circuit the inside of the vaporization chamber 3, merges with the steam that has been discharged from the steam passage 13, and is discharged to the lower surface spray nozzle 14. When they join, the water is crushed into a mist with the momentum. Further, the pulverized water and steam are sprayed from the recess 15 having a concave shape on the bottom surface of the iron base 1 via the lower surface spray nozzle 14. As a result, sufficient moisture can be given only to the clothes below the iron base, and there is no need for work before the spraying process.

It is a positional relationship. Other components are the same as those in FIGS. Here, the spray from the front part of the iron main body is shown in FIG.

The branch water conduit 12 and the steam passage 13 merge, and the water and steam pulverized in the vaporization chamber 3 are sprayed from the front part of the iron body through a plurality of cross spray nozzles 17 by the steam. I do. Then, since the streamlines of the mist ejected from the spray holes have a positional relationship of intersecting with each other, the mist collide with each other and are further finely crushed, so that the mist is sprayed evenly on the clothing surface. As a result, a spray-type iron that can provide sufficient moisture to clothing without the need for a pre-working process before the spraying process and that can provide a good finish to vegetable fibers such as cotton and hemp. Is what you do.

(Embodiment 4) Next, Embodiment 4 of the present invention will be described with reference to FIG. In the present embodiment, a recess 15 having a concave shape on the bottom surface of the iron base 1 or a multi-hole spray nozzle 18 having a plurality of spray holes located in the front part of the iron main body. The same is true. Here, the spray from the front part of the iron main body is shown in FIG. Here, the plurality of spray holes are oriented in multiple directions so as to be able to apply moisture to the clothing evenly and widely. Therefore, an operator can provide a spray-type iron that can give sufficient moisture to clothing over a wide range, and can make vegetable fibers such as cotton and hemp to be in a good finish.

(Fifth Embodiment) Next, a fifth embodiment of the present invention will be described with reference to FIG. In the present embodiment, the streamlines of the mist ejected from the outlet intersect each other at the recessed recess 15 on the bottom surface of the iron base 1 or the slit spray hole nozzle 19 having a slit-shaped spray hole located at the front of the iron body. It has a positional relationship. Other components are the same as those in FIGS. Here, the spray from the front part of the iron main body is shown in FIG. As in the third embodiment, the branch water conduit 12 and the steam passage 13 merge, and the water and steam pulverized in the vaporization chamber 3 are supplied to the iron via the plurality of slit spray hole nozzles 19 by the steam. It is sprayed from a recessed recess on the bottom surface of the base 1 or from the front of the iron body. Then, the mist collides with each other and is further finely crushed and sprayed evenly on the clothing surface. Furthermore, since the spray hole has a slit shape, the mist collides while diffusing. Therefore, an object of the present invention is to provide a spray iron that can provide a wide range of moisture to clothes.

(Embodiment 6) Next, Embodiment 6 of the present invention will be described with reference to FIG. In the present embodiment, the plurality of mist passages 20 located in the recessed recess 15 on the bottom surface of the iron base 1 or the front part of the iron body communicate with each other.
Mist is sprayed from at least one mist spray hole 21. Since the plurality of mist passages 20 communicate with each other, mist coming from each direction collides efficiently and is further finely pulverized. Therefore, an object of the present invention is to provide a spray iron that can uniformly impart moisture to clothes.

(Embodiment 7) Next, Embodiment 7 of the present invention will be described with reference to FIG. In FIG. 7, reference numerals 1 to 15 denote members similar to those in the configuration described in FIG. In this embodiment, a communicating water channel 21 having the following configuration is provided between the water tank 5 and the main water channel 11. That is, the communication water passage 21 of the present embodiment is provided with the piston 2
And a water suction passage 24 for absorbing water in a water tank 5 provided below the cylinder 23.

-It is sent into the vaporization chamber 3 through the headwater channel 11.

The ratio between the amount of water sent to the steam passage 13 and the amount of water sent to the branch conduit 12 is determined by the ratio of the cross-sectional areas of the passages, and is supplied at a predetermined ratio. At this time, although the pressure in the vaporization chamber 3 increases, the cross-sectional area of the steam passage 13 is large, while the diameter of the branch water conduit 12 is very small, and the steam button 28 is pressed. Since the pressure in the water channel 11 is high, the pressure in the main water channel 11 is hardly affected by the pressure in the vaporization chamber 3 and there is no backflow of steam.

In this way, as in the first embodiment, the branch conduit 1
The water sent from 2 is pulverized into a mist while being mixed with steam, and further passed through at least one lower surface spray nozzle 14 to form a recessed recess 15 on the bottom surface of the iron base 1 or from the front of the iron body. It sprays evenly on the surface.

When the pressing force on the steam button 28 is removed, the piston 22 moves up in the cylinder 23 by the urging force of the urging spring 29. As a result, cylinder 2
The pressure in 3 becomes negative pressure than in water tank 5. Therefore, the water in the water tank 5 is sucked into the cylinder 23 through the water suction passage 24 while opening the water suction check valve 25. Therefore, the cylinder 23 is again filled with water.

By repeatedly applying and releasing the pressing force to the steam button 28 as described above, the cylinder 23 and the piston 22 perform a pumping operation to supply the water in the water tank 5, and the worker Provides a spray iron that can spray a certain amount of mist by pressing a steam button when mist is desired.

[0032]

As described above, according to the present invention, it is possible to give sufficient moisture to the clothes below and in front of the iron base, and there is no need for a work before the spraying process. In the same ironing procedure as steam irons, when you want to apply mist to the part you want to stretch out wrinkles, just move the iron body freely back and forth, left and right, and with a good finish on vegetable fibers such as cotton and hemp. This has the advantageous effect that it can be performed.
