Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a spray-type iron used for wrinkling clothing and the like in a general household.
[0002]
[Prior art]
Ironing requires three elements of “temperature”, “moisture”, and “pressure”, and steam irons that satisfy these elements are becoming increasingly popular. However, in the case of vegetable fibers such as cotton and linen, steam is less effective, and a larger amount of water is required. For this reason, spray-type irons have become widespread in recent years. As this type of spray-type iron, one having a configuration as shown in FIG. 6 is generally used. Hereinafter, the configuration will be described.
[0003]
Reference numeral 101 denotes an iron base for stretching the wrinkles of clothing, and reference numeral 102 denotes a handle attached to the upper surface of the iron base 101. The handle 102 includes a water tank 103. Reference numeral 104 denotes a cylinder having a check valve 105 at the bottom and a fountain port 106. Reference numeral 107 denotes a nozzle that protrudes outward through the front wall of the handle 102, and is connected to the fountain port 106 through a water conduit 108. 109 is a piston inserted into the cylinder 104 so as to be slidable up and down. The upper end of the piston protrudes outward from the cylinder 104. The piston 111 is fixed to the upper end, and the spring 111 contracted between the cylinder 104 is constantly rising. Is energized. Reference numeral 112 denotes a push button that freely protrudes and retracts from a through hole 113 in the upper part of the handle 102, and its lower surface is engaged with the upper end of the piston 109.
[0004]
With the above configuration, it operates as follows. When the handle 102 is held and the push button 112 is pressed with the thumb, the piston 109 moves down in the cylinder 104 against the spring 111. When the piston 109 descends in the cylinder 104, the check valve 105 is closed in the water in the cylinder 104. Therefore, as the piston 109 descends, the water passes through the fountain port 106 and the water passage 108, and is located in front of the handle 102 from the nozzle 107. Sprayed on clothing performing ironing.
[0005]
Next, when the pressing force with respect to 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 a negative pressure from the water tank 103. Therefore, the water in the water tank 103 is sucked into the cylinder 104 while opening the check valve 105. Therefore, the cylinder 104 is again filled with water, and the check valve 105 is closed again.
[0006]
When the push button 112 is pressed again in this state, the water in the cylinder 104 is sprayed from the nozzle 107 in the same manner as described above. In this way, by repeatedly urging / releasing the pressing force to the push button 112, the cylinder 104 and the piston 109 perform a pump action to spray water in the water tank 103.
[0007]
[Problems to be solved by the invention]
However, in the conventional configuration, the mist is sprayed in front of the iron body. For this reason, as a procedure for ironing, the operator first lifts the iron body and applies the mist to the entire garment, and then presses the iron body to crease the wrinkle, or puts the iron on the garment and puts the mist on it. One that either slides the iron body in the direction it comes out while wringing it out and wrinkles and stretches, it takes time for the previous work, or the direction of ironing is restricted, so it is difficult to do very much work Met. Moreover, since mist spreads widely, there also existed a problem that mist flew to the surrounding thing other than the part which is not ironed or clothing.
[0008]
The present invention is intended to solve the problems of such a conventional configuration, and does not require any prior work, and the cotton body can be moved in the same ironing operation as a normal steam iron while moving the iron body freely back and forth and left and right. -It aims at providing the spray type iron which can implement | achieve a favorable finishing state also for plant fibers, such as hemp.
[0009]
[Means for Solving the Problems]
In order to solve this problem, the present invention includes a steam mixed in a mixing chamber and a diffusion nozzle that ejects mist, and the diffusion nozzle has a tip opening near the bottom of a recess-shaped recess formed in the iron base. And the openings are provided so as to face each other horizontally .
[0010]

The front end opening is located in the vicinity of the bottom surface, and the openings are provided so as to face each other horizontally . As a result, sufficient moisture can be given only to the clothing under the iron base, and there is no pre-working of the spraying process, and the operator can stretch the wrinkles in the same way as ironing with a normal steam iron. By simply moving the iron body back and forth and right and left freely to the desired part, it is possible to achieve a good finished state for vegetable fibers such as cotton and linen . Further, since the spraying is performed from the horizontally opposed diffusion nozzles, the mists collide with each other and further finely pulverized and sprayed evenly on the clothing surface.
[0011]
The invention described in claim 2 of the present invention is provided with a communicating water channel while guiding the water in the water tank to the water channel, and the cylinder constituting the communicating water channel slides up and down in the cylinder and always has an upward tendency. A piston urged by an urging spring, a piston shaft fixed to the piston, a steam button for pushing with a finger provided at the upper end of the piston shaft, a water absorption path for absorbing water in the water tank, and a water absorption reverse This is provided with a stop valve and a water supply path for supplying water in the cylinder to the water conduit, and when the steam button is pressed, the piston moves down in the cylinder against the biasing spring.

When the piston descends in the cylinder, the water in the cylinder is fed to the water conduit through the water supply / steam check valve as the piston descends because the water absorption check valve closes and the steam check valve opens. However, when the pressure in the cylinder becomes higher than the pressure in the water conduit due to the vapor pressure, the spring body contracts and the piston is not lowered even if the steam button is pressed, and the state is maintained. When the steam pressure eventually decreases and the pressure in the water conduit becomes lower than the pressure in the piston, the spring body again pushes down the piston and descends, the water in the piston is sent to the water conduit, the steam pressure rises again, and the water pressure on the water conduit side The operation of increasing the internal pressure will be repeated. By increasing the size of the cylinder, the operator can continuously spray the mist for a predetermined time by continuously pressing the steam button.
[0013]
【Example】
Example 1
A first embodiment of the present invention will be described below with reference to FIGS. Reference numeral 1 denotes an iron base heated by an embedded heater 2. A vaporization chamber lid 5 that forms the upper portion of the iron base 1 forms a vaporization chamber 3 that generates steam and a steam passage 4 that communicates with the vaporization chamber 3. 6 is a water tank, 7 is a water tank outlet passage formed at the bottom of the water tank 6, 8 is an opening / closing shaft, and is always urged upward by an opening / closing spring body 9, and is joined to the upper end of the opening / closing shaft 8. When the operator presses the steam button 10, a latch mechanism (not shown) works, and the lower end portion of the open / close shaft 8 having a substantially hemispherical shape can close the entrance of the water tank outlet passage 7. A steam check valve 11 communicates with the water tank outlet passage 7. Reference numeral 12 denotes a water conduit for communicating water in the water tank 6 to the vaporization chamber 3 in communication with the steam check valve 11 .
[0014]
13 is a mist passage branched in the middle of the water conduit 12, and 14 is a substantially cylindrical mixing chamber disposed near the upper end of the iron base 1. Both the steam passage 4 and the mist passage 13 communicate with the mixing chamber 14. The steam outlet at the front end of the steam passage 4 protrudes into the mixing chamber 14 from its bottom surface, and the outlet opening is formed on the side surface near the front end of the protruding steam passage 4, and the outer peripheral tangential direction of the bottom surface of the mixing chamber 14 The water tank that is opened to the steam passage 4 and is introduced from the steam passage 4 into the mixing chamber 14 in a circular arc along the inner wall of the mixing chamber 14 as shown in FIG. 6 is mixed with water from 6. 2 and 3, reference numeral 15 denotes two diffusion nozzles which communicate with the mixing chamber 14 and whose opening at the front end is located in the vicinity of the concave recess on the bottom surface of the iron base 1, with the lower end outlets facing each other. It has become a positional relationship.
[0015]
The operation of this embodiment will be described below. First, when the operator presses the steam button 10 to release the latch mechanism, the opening / closing shaft 9 is restrained upward by the urging force of the opening / closing spring 8 and the water tank outlet passage 7 is opened. Then, the water in the water tank 6 is dropped into the vaporization chamber 3 through the water tank outlet passage 7, the steam check valve 11, and the water conduit 12 due to the head difference. The water dripped into the vaporizing chamber 3 becomes steam. And the internal pressure of the vaporization chamber 3 and the water conduit 12 rises temporarily by the phase change when this water turns into steam, and the steam check valve 11 is closed.
[0016]
Then, the steam generated in the vaporizing chamber 3 is ejected from the steam passage 4 to the mixing chamber 14, and at the same time, the steam flows backward through the water conduit 12 and also ejects from the mist passage 13 to the mixing chamber 14. At this time, the water in the water conduit 12 is also spouted into the mixing chamber 14 together with steam. As described above, the steam outlet opening at the tip of the steam passage 4 opens in the outer circumferential tangent direction in the mixing chamber 14, and the steam guided in the mixing chamber 14 extends along the inner wall of the mixing chamber 14. Therefore, the steam is swirled in the mixing chamber 14 and the water is pulverized in a mist form.
[0017]
Further, the mist and steam crushed in the mixing chamber 14 are sprayed through the two diffusion nozzles 15 so as to be horizontally opposed from the concave recess 1 a on the bottom surface of the iron base 1. Then, the mists collide with each other and are further finely crushed and sprayed evenly on the clothing surface. Since the recess 1a in the shape of the bottom surface of the iron base 1 provided in the periphery of the opening of the diffusion nozzle 15 is formed in the base, the depth of the recess is shallow, and the clothes move when the iron is operated. Without interfering with the ironing operation, the mixture of steam and mist sprayed from the diffusion nozzle 15 adheres to the clothing as a high temperature mist, and is quickly pressed against the iron base 1 without lowering the temperature. Therefore, wrinkles of clothing can be extended efficiently and reliably. The recess 1a having a concave shape on the bottom surface of the base is not a space isolated from the outside, and preferably a larger portion communicating with the outside promotes diffusion of the mixture of steam and mist. When scrubbing, a lot of hot mist, etc. is ejected from the iron base, so that the user's usability is reduced.Therefore, it has a communicating part with the outside so that the diffusion of the mixture of steam and mist is not insufficient. is necessary. If the communicating portion is provided in the direction of the side surface of the iron, smooth ironing can be realized without hindering the movement of the iron.
[0018]
Further, since a mixture of steam and mist is sprayed from the diffusion nozzle 15, the temperature of the iron base is not lowered due to the spraying of the low temperature mist, and the high temperature mist quickly diffuses into the clothing. At the same time, since it is pressed by the iron base having a low temperature drop, strong wrinkles can be surely eliminated.
[0019]
According to the present embodiment, sufficient moisture can be given only to the clothing under the iron base, and there is no pre-working of the spraying process, and the operator performs the wrinkling in the same ironing procedure as a normal steam iron. By simply moving the iron main body back and forth and right and left freely at the part to be stretched, a spray-type iron that can achieve a good finish on vegetable fibers such as cotton and linen is provided.
[0020]
(Example 2)
Next, a second embodiment of the present invention will be described with reference to FIG. In FIG. 4, reference numerals 1 to 15 denote members similar to those described in FIGS. 1, 2, and 3. In this embodiment, there is provided a communication water passage which is configured as follows between the water tank 6 and the water conduit 12. That communication water passage of the present embodiment includes a cylinder 18 having a piston 19 inserted vertically slidably therein, a water passage 24 for water absorption of water in the water tank 6 which is provided in the lower portion of the cylinder 18 The water absorption check valve 23 provided in the water absorption path 24 and the water supply path 17 for supplying the water in the cylinder 18 to the water conduit 12 are constituted.
[0021]
Reference numeral 21 denotes a piston shaft to which a piston 19 is fixed, and an upper end protrudes outward from the cylinder 18 and is connected to a steam button 20 protruding upward. Reference numeral 22 denotes an urging spring that pulls the piston shaft 21 upward, whereby the piston shaft 21 is always urged upward.
[0022]
The operation of this embodiment will be described below. When the user presses the steam button 20 with the thumb, the piston 19 moves down in the cylinder 18 against the biasing force of the biasing spring 22 . When the piston 19 descends in the cylinder 18, the water in the cylinder 18 is closed in the vaporization chamber 3 and the water conduit through the water supply passage 17 and the water conduit 12 as the piston 19 descends because the water absorption check valve 23 is closed. It is fed into the mixing chamber 14 through the mist passage 13 branched from the portion 12.
[0023]
The ratio of the amount of water sent into the vaporizing chamber 3 and the amount of water sent into the mixing chamber 14 is determined by the ratio of the cross-sectional areas of the respective passages, and is supplied at a predetermined ratio. For this reason, the steam generated in the vaporizing chamber 3 is concentrated and ejected through the steam passage 4 and into the mixing chamber 14. At this time, the pressure in the vaporizing chamber 3 has a large diameter of the steam passage 4 which rises, whereas the possible diameter of the headrace 12 is very small, since presses the steam button 20, the piston 19, the water conduit 12 Since the internal pressure is high, the pressure in the water conduit 12 is hardly affected by the pressure in the vaporization chamber 3, and there is no backflow of steam.
[0024]
In this way, the water sent into the mixing chamber 14 is pulverized while being mixed with steam to form mist as in the first embodiment, and further passes through the two diffusion nozzles 15 to form the concave shape on the bottom surface of the iron base 1. sprayed horizontally oppositely from depression, it is to uniformly sprayed more finely ground with garment surface mist each other collide with each other.
[0025]
When the pressing force on the steam button 20 is removed, the piston 19 moves up in the cylinder 18 by the biasing force of the biasing spring 22 . As a result, the pressure in the cylinder 18 becomes negative from that in the water tank 6. For this reason, the water in the water tank 6 is sucked into the cylinder 18 from the water absorption passage 24 while opening the water absorption check valve 23 . For this reason, the cylinder 18 is again filled with water.
[0026]
The cylinder 18 and the piston 19 perform the pumping action by repeating the urging / releasing of the pressing force to the steam button 20 in this way, and the water in the water tank 6 is sent. The present invention provides a spray-type iron that can spray a certain amount of mist by pressing a steam button when desired.
[0027]
Example 3
Next, a third embodiment of the present invention will be described with reference to FIG. In FIG. 5, reference numerals 1 to 15 denote members similar to those described in FIGS. In this embodiment, a spring body 29 is newly interposed between the piston 28 and the piston shaft 32 in FIG. 4 so as to constantly bias the piston 28 downward from the lower end of the piston shaft 32 .
[0028]
The operation of this embodiment will be described below. When the operator presses the steam button 31 with the thumb, the piston shaft 32 descends against the urging force of the urging spring 33 , and the spring body 29 is compressed. The compressed spring body 29 urges the piston 28 in the descending direction, and the piston 28 gradually descends in the cylinder 27 .
[0029]
At this time, since the water absorption check valve 34 is closed, the water in the cylinder 27 passes through the water supply passage 26 and the water conduit 12 as the piston 28 descends, and the mist passage 13 branched from the vaporization chamber 3 and the water conduit 12. Then, it is sent into the mixing chamber 14. The water dripped into the vaporizing chamber 3 instantaneously becomes steam, and the pressure in the vaporizing chamber 3 increases. Then, the pressure in the water conduit 12 also rises due to the pushing back of the steam pressure, but the steam check valve 11 is closed because the internal pressure of the water conduit 12 is larger than the internal pressure of the cylinder 27 , and the piston 28 is lowered by the spring body 29. The stationary state is maintained while being energized.
[0030]
As time elapses and the vapor pressure in the vaporizing chamber 3 begins to drop, the pressure in the cylinder 27 becomes higher than the pressure in the vaporizing chamber 3 and the water conduit 12, and the spring body 29 pushes down the piston 28 . The water in the piston 28 is sent to the water conduit 12 and the vaporizing chamber 3, the vapor pressure rises again, the internal pressure of the vaporizing chamber 3 and the water conduit 12 is increased, and the piston 28 stops repeatedly. It will be. By enlarging the cylinder 27 , the operator can continuously diffuse and spray for a predetermined time if the steam button is continuously pressed.
[0031]
Since the passage area of the mist passage 13 is sufficiently small, the amount of water flowing from the mist passage 13 into the mixing chamber 14 is small, and does not have a rapid effect on the pressure in the water conduit 12. It can be considered that the pressure change of the water guide channel 12 is almost synchronized with the pressure change of 3.
[0032]
In this way, the water sent into the mixing chamber 14 is pulverized while being mixed with steam into mist as in the first and second embodiments, and further passes through the two diffusion nozzles 15 to reach the bottom surface of the iron base 1. the sprayed horizontally opposed to from depression of concave shape, is intended to equally sprayed onto the garment surface is further finely divided mist with each other collide with each other, when the stretch stubborn wrinkles clothing such as cotton, hemp Can be used as a suitable spray iron.
[0033]
By the way, in this case, the piston 28 is gradually lowered by the spring body 29 so that the water in the cylinder 27 is supplied. Therefore, if the diameter of the cylinder 27 is increased, the steam button 31 can be pressed once. A long and stable continuous spray can be obtained, and a uniform and good finished state of clothing can be obtained.
[0034]
Further, if the steam button 31 can be locked at the lower end, it becomes a spray iron that is more convenient to use.
[0035]
【The invention's effect】
As described above, according to the present invention, sufficient moisture can be given only to the clothing below the iron base , and the mist can be finely pulverized and sprayed onto the clothing. No need to leave, the operator can use the same ironing procedure as a normal steam iron, and move the iron body back and forth and right and left freely to the part where you want to stretch the wrinkle. Can be realized .
