DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art Conventionally, this type of iron has the configuration shown in FIG. Referring to FIG. 8, the iron body 1 includes a base 4 having a vaporization chamber 3 covered with a lid 2, a heater 5 for heating the base 4, and water disposed above the base 4. And a pump device 8 for supplying the water in the water tank 6 to the water channel 7.

The pump device 8 includes a mist button 9 formed on the upper part of the water tank 6 so as to be movable up and down, a piston 11 that slides up and down in a cylinder 10 by operating the mist button 9, and a mist button 9. And a button spring 12 that urges the button spring. The cylinder 10 is provided with a pumping passage 13 below, a check valve 14 made of steel balls or the like for opening and closing the pumping passage 13, a discharge passage 15 for supplying water in the cylinder 10 to the water passage 7, A valve 16 for opening and closing the discharge path 15 and a spring 17 for urging the valve 16 to close the discharge path 15 are provided.

[0004] The water channel 7 is provided above the lid 2 and has a first passage 18 for guiding water in the water tank 6 to the vaporization chamber 3 and a second passage 18 for guiding water in the water tank 6 to the mixing chamber 19. Passage 20 of
It has a steam passage 21 for guiding steam generated in the vaporization chamber 3 to the mixing chamber 19. The mixing chamber 19 is provided with a second water passage 20.
It is formed in a dome shape upward, and its upper surface protrudes from a base cover 22 that covers the upper surface side of the base 4 and is exposed outside the iron main body 1. Also, 23
Are two diffusion nozzles which communicate with the mixing chamber 19 and whose leading end openings are located near the recessed recesses on the bottom surface of the iron base 4, and whose lower end outlets are opposed to each other.

The operation of the above arrangement will be described.
When ironing while supplying water by spraying mist onto hardly stretchable fibers such as hemp or fibers with particularly high wrinkles, first press the mist button 9 against the urging force of the button spring 12. When the mist button 9 is released after the piston 11 is lowered, the pressure of the button spring 12 causes the piston 11 to rise in a negative pressure in the cylinder 10.

At this time, the discharge passage 15 is closed by the valve element 16 and the check valve 14 is opened to allow the water in the water tank 6 to flow into the cylinder 10 via the water pumping passage 13.
When the mist button 9 is pressed again to lower the piston 11, the check valve 14 closes the pumping path 13, so that about 1 ml of water stored in the cylinder 10 pushes down the valve body 16 and instantaneously. The water is supplied to the water channel 7.

The water supplied into the water channel 7 is branched into two systems, a first water channel 18 communicating with the vaporizing chamber 3 and a second water channel 20 communicating with the mixing chamber 19. First waterway 18
Is instantaneously evaporated into the vaporization chamber 3 and supplied to the mixing chamber 19 through the steam passage 21 as steam. on the other hand,
The water from the second water conduit 20 is sent directly to the mixing chamber 19, but due to the flow velocity of the steam ejected from the steam passage 21,
It becomes fine granular.

Further, the water and steam pulverized in the mixing chamber 19 are sprayed through two diffusion nozzles 23 so as to face horizontally from a concave-shaped recess on the bottom surface of the iron base 4. Then, they collide with each other, are further finely ground, and are sprayed evenly on the clothing surface.

[0009]

However, in such a conventional structure, the water sprayed by the two diffusion nozzles 23 must be pulverized at a steam flow rate to make the water fine.
For this purpose, the passage area of the diffusion nozzle 23 had to be narrowed. However, due to the configuration in which water is used as steam, scale formed of calcium ions and the like contained in the water precipitates in the vaporization chamber 3, and a part of the water scale enters the mixing chamber 19 together with the steam, and as described above. There was a problem that the diffusion nozzle 23 was clogged with the scale.

In the mixing chamber 19, water is jetted out of the steam passage 21 to form fine particles due to the flow velocity of steam. However, since the passage of the diffusion nozzle 23 is narrow, water is recombined while passing therethrough. There is also a problem that water is recombined even in the mixing chamber 19 due to the formation of large water masses and the flow being blocked, which makes it impossible to atomize water.

That is, in the configuration of the conventional example, first, there is a problem that it is difficult to take measures for removing scale, and secondly, there is a problem that the particle size of the fog tends to vary. Third
In addition, there was a problem that water that could not be jetted into the mixing chamber 19 easily remained and was pushed out as it was without being atomized. Fourthly, since the mixing chamber 19 is exposed, the user can easily touch the mixing chamber 19 with his / her hand, and there is also insecurity such as burns.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems, and can surely take measures to remove water scale, suppress variation in the particle size of the sprayed mist, and realize stable spraying of fine particles. The purpose is to prevent residual water, prevent water from jumping out, and prevent burns.

[0013]

In the iron of the present invention, a slit-shaped ejection nozzle is formed in the mixing chamber, and the opening is formed so that the opening angle in the horizontal direction is about 100 degrees and the vertical angle is about 1.5 mm. By forming with the width in the direction, the scale that has entered the mixing chamber is also ejected to the outside together, and furthermore, the variation of the particle size of the sprayed mist is suppressed, and the stable fine particle size spray is realized, Further, it is intended to prevent residual water and prevent water from jumping out, and to prevent inconvenience caused by hot parts of the iron.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention described in claim 1 of the present invention is directed to a water tank for storing water, a pump device provided in the water tank, and steam generated by vaporizing the water in the water tank. A base in which a vaporization chamber to be formed is formed, a first water conduit for guiding water in the water tank to the vaporization chamber, a mixing chamber for granulating the water in the water tank by the flow rate of steam, A second water conduit for guiding the water to the mixing chamber,
A steam passage for guiding the steam generated in the vaporization chamber to the mixing chamber, wherein the mixing chamber has a side surface protruding in the direction of the tip of the iron, and a slit-shaped jet in a horizontal direction is formed at an upper part of the side surface. A nozzle is formed, and the scale that has entered the mixing chamber can be ejected to the outside together.
In addition, the fine mist can be spread in a fan shape and sprayed in a predetermined range. From the results of actual use experiments, it was found that the optimum spraying range for efficiently wetting the cloth should be widened to a width substantially equal to the width of the iron to a substantially fan-shaped range from the vicinity of the iron tip to about 150 mm ahead. ing. The jet nozzle of the present invention has a spread angle of about 100 degrees and a slit shape with a thickness of about 1.5 mm, so that water scale that has entered the mixing chamber can also be jetted to the outside,
The fine mist is spread in a fan shape and is sprayed, and has an optimum shape for spraying the optimum spray range.

According to a second aspect of the present invention, in addition to the first aspect, the ejection nozzle has a shape in which the upper surface and the lower surface of the opening are inclined in the forward direction of the iron.
Even if the mist is not sprayed while holding the iron by hand and tilting obliquely, it is possible to spray the iron in a predetermined spray range while sliding the iron horizontally. According to a third aspect of the present invention, in addition to the second aspect, the inclination of the lower surface of the opening is made larger than that of the upper surface without changing the cross-sectional area of the ejection nozzle, so that the mist particle diameter remains unchanged. Thus, the spray range in the front-back direction can be expanded.

According to a fourth aspect of the present invention, in addition to the second aspect, the tank tip of the water tank extends to the front of the mixing chamber and is formed along the lower surface of the ejection nozzle. Since the fog spouted from the spout nozzle in a slit shape is spouted along the tank tip, the air in a slight gap between the two is pulled by the spray, and the pressure becomes slightly negative. Then, the mist ejected at the inclination angle of the slit is ejected further inclined downward by the action of the downward force. Further, since the angle is proportional to the speed of the fog, initially, as the flow rate of the fog becomes faster and gradually slows down, the jetting angle of the fog initially spouts at a steep angle, but the angle gradually becomes gentler. This makes it possible to spread the mist finely in a slit shape in the width direction of the jet and to widen the spray range also in the front-back direction.

According to a fifth aspect of the present invention, in addition to the first aspect of the present invention, the mixing chamber is formed in a substantially triangular prism shape, and one of the sharp ends thereof is disposed in front of the iron. With the configuration in which the ejection nozzle is formed at the upper portion, compared to the cylindrical mixing chamber, the inside of the mixing chamber becomes tapered as it approaches the vicinity of the ejection nozzle, and the passage cross-sectional area gradually decreases, and The water and the steam can be surely mixed while the water that has entered the mixing chamber is crushed and pressed by the steam that has entered from behind according to a certain movement without being disturbed. And since it is opened to the atmosphere at the ejection nozzle portion where the passage cross-sectional area is the narrowest, it is opened to the atmosphere immediately after the pressure becomes highest, so that mist having a uniform particle size can be generated.

According to a sixth aspect of the present invention, in addition to the first aspect of the present invention, the mixing chamber is formed in a substantially triangular prism shape, and a jet nozzle is positioned near the tip thereof, and the bottom of the mixing chamber is jetted from behind the iron. By adopting a configuration inclined toward the nozzle side, the inside of the mixing chamber is tapered as it approaches the vicinity of the ejection nozzle, and the cross-sectional area of the passage is gradually reduced, similarly to the fifth embodiment. The water that has entered can be reliably pressed and crushed by the steam that has entered from behind, and at the same time the remaining water that has not completely crushed in the mixing chamber and the dewed water is farthest from the jet nozzle due to the inclination of the bottom. Since it returns to the vicinity of the steam passage located at the place, it can be surely crushed by the next spraying operation.

According to a seventh aspect of the present invention, in addition to the first aspect of the present invention, a mixing chamber rib is provided for partitioning the mixing chamber back and forth, and an opening is provided along the bottom of the mixing chamber below the mixing chamber rib. It is possible to prevent the water fed into the mixing chamber from directly flowing out of the jet nozzle before being crushed by steam.
Further, since an opening is formed below the mixing chamber rib along the bottom surface of the mixing chamber, residual water does not remain.
In addition, due to the effect of the ribs, the steam and water that hit the ribs rise in the mixing chamber, forming a constant vortex in the vertical direction, returning to the steam passage once again, and crushing with the subsequent steam, making the mist finer There is also an effect.

According to an eighth aspect of the present invention, in addition to the seventh aspect, the space partitioned by the mixing chamber ribs is configured such that the front space is smaller in volume than the rear space. Only the mist that is surely formed by this configuration is ejected from the ejection nozzle. According to a ninth aspect of the present invention, in addition to the seventh aspect, the opening area of the opening provided at the lower portion of the mixing chamber rib is larger than the opening area of the ejection nozzle. By
Further, the size of the mist becomes uniform and the mist is sprayed.

According to a tenth aspect of the present invention, in addition to the first aspect of the present invention, an inner wall rib for closing a steam retaining space formed on both sides of the mixing chamber is provided, and a portion where water easily accumulates is eliminated. Thus, it is difficult to collect residual water. In the invention according to claim 11, in addition to the invention according to claim 1, by making the mixing chamber transparent, the operator can visually recognize that high-temperature steam passes through the inside of the mixing chamber, The act of inadvertently touching the hot mixing chamber with the hand can be prevented.

According to a twelfth aspect of the present invention, in addition to the first aspect, the water tank is provided with a transparent mixing chamber cover for covering the mixing chamber, and the high-temperature mixing chamber is touched by hand. The safety is improved by not being able to do it.

[0023]

Embodiments of the present invention will be described below with reference to the drawings. The same components as those in the conventional example are denoted by the same reference numerals, and description thereof is omitted. (Embodiment 1) A first embodiment of the present invention will be described below with reference to FIGS. Since the basic structure is the same as that of the conventional example, the same reference numerals are given and the description is omitted.

First, in FIG. 1, reference numeral 24 denotes a mixing chamber having a triangular prism dome shape as shown in FIG. The detailed configuration of the mixing chamber 24 will be described with reference to FIGS. 3, 4, and 5. The mixing chamber 25 connects the steam passage 21 and the second water conduit 20 to one passage and feeds the mixture into the mixing chamber 24. At the entrance to the room, it is installed horizontally from the lower center of the side. Reference numeral 26 denotes an upper portion of the mixing chamber made of a transparent resin or the like constituting the main body of the mixing chamber 24, and 27 denotes a lower portion of the mixing chamber, which is adhered by ultrasonic welding or the like so as not to leak water. Reference numeral 28 denotes a jet nozzle which is formed in the upper part of the side surface of the mixing chamber upper part 26 protruding in the direction of the tip of the iron in the form of a slit in the horizontal direction.
There is a spread of 0 degrees and a width of 1.5 mm in the vertical direction,
It is inclined 15 degrees in front of the iron.

The lower part 27 of the mixing chamber is inclined so that the jet nozzle 28 side is higher from the back of the iron. 29 is the upper part of the mixing chamber 2 to partition the mixing chamber 24 back and forth.
6, an opening is formed along the mixing chamber lower part 27 at the lower part of the mixing chamber rib. The space partitioned by the mixing chamber rib 29 is such that the volume in the front space is smaller than that in the rear space. Reference numeral 30 denotes an inner wall rib for closing a steam retaining space formed on both sides of the mixing chamber 24, and is provided at symmetrical positions. Further 31
2 is a front end of the water tank 6, which extends to the front of the mixing chamber 24 and is provided along the lower surface of the jet nozzle 28, as shown in FIGS. Reference numeral 32 denotes a mixing chamber cover made of a transparent resin or the like that covers the mixing chamber 24 provided in the water tank 6.

The operation of the above configuration will be described. By pressing the mist button 9 as in the conventional example, the water pressure-fed from the pump device 8 and supplied into the water passage 7 is supplied to the vaporization chamber 3.
And a second water conduit 20 communicating with the mixing chamber 24. Water from the first water conduit 18 evaporates in the vaporization chamber 3 and is supplied as steam from the steam passage 21 to the mixing chamber 24 through the mixing chamber inlet 25. On the other hand, the water from the second water conduit 20 is directly sent to the mixing chamber 24 through the mixing chamber inlet 25.

The water fed into the mixing chamber 24 is first finely crushed at the mixing chamber inlet 25 by the flow rate of steam, and is fed into the mixing chamber 24 from a horizontal direction. First, only the crushed water and steam directly passing through the small passage by the mixing chamber rib 29 reach the tip of the mixing chamber 24 and are jetted in a slit shape from the jet nozzle 28. Next, the water colliding with the mixing chamber rib 29 becomes coarse particles due to the collision with the wall surface or the recombination due to the collision between the waters.
And returns to the mixing chamber inlet 25 again, and is pulverized again by the flow rate of the subsequent steam. That is, a constant swirling flow is generated in the mixing chamber 24, and the water is refined many times. Only the completely refined water passes through the small passage by the mixing chamber rib 29 to the spray nozzle 28 at the tip. Something that can be reached. Moreover, the swirling flow flows efficiently because the steam retaining space is closed by the inner wall rib 30.

Considering the timing of the water and the steam fed into the mixing chamber 24, the water is immediately blown in at the moment when the mist button 9 is pressed, but the steam needs time for the water to evaporate in the vaporization chamber 3. Then, the water is gradually sent to the mixing chamber 24 a little later than the timing at which the water is sent. Therefore, if water is to be jetted from the spray nozzle 28 at one time, the flow velocity of the steam is too weak, and as a result, water may be jetted without being completely crushed. However, if the spray is not sprayed at once but is gradually sprayed as in the present invention, steam can be used effectively, and fine and long spray can be performed.

Further, since the spray nozzle 28 is provided at the tip of the mixing chamber 24, the cross-sectional area of the passage is gradually reduced to the minimum. Therefore, the spray nozzle 28
Immediately before, the pressure becomes the highest, and spraying into the air is performed at a stretch. Therefore, the pressure difference can be made highest, and the atomization can be promoted. Moreover, even if water remains in the mixing chamber 24 by a single spraying operation, the water returns to the vicinity of the mixing chamber inlet 25 because the lower part of the mixing chamber 27 is inclined. Even if it is tilted, water or hot water does not spill out of the spray nozzle 28, and can be crushed again by the flow rate of steam entering from the mixing chamber inlet 25 at the start of the next spraying operation.

The mist atomized at once from the spray nozzle 28 spreads 100 degrees in the horizontal direction along with the shape of the spray nozzle along with the steam, and 1.5 mm in the vertical direction.
Spouted at an angle of 15 degrees toward the front of the iron. However, since the opening of the jet nozzle 28 has a slit shape and has a width of 1.5 mm, even if water scale mixes with steam and enters, it can be discharged to the outside together. is there. In addition, since the gas is ejected along the tank tip 31, the air in the slight gap between the fog and the tank tip 31 is pulled by the fog, so that the pressure becomes slightly negative, and the fog ejected obliquely downward acts as a downward force. Is ejected while tilting further downward.

Since the angle is proportional to the speed of the fog,
At first, as the flow rate of the fog becomes faster and gradually slower, the fog ejection angle also initially spouts at a steep angle, but the angle gradually becomes gentler. This makes it possible to increase the spray range of the fog in the front-rear direction. As a result, the spraying range is almost the same size as the width of the iron in the width direction, and is a fan-shaped range from the vicinity of the front end of the base 4 to about 150 mm ahead in the front-rear direction (the range indicated by hatching in FIG. 2). The spray can be sprayed in the most convenient spray range obtained from the results of use experiments.

Further, as a further effect of the tank tip 31, even when a fog having a large particle size or a lump of water is mixed and spouted, the coarse fog or the lump of water is heavy, so that the tank 31 has a heavy weight. Adhere to. However, it can be pulverized by the flow rate of the subsequent fog or steam, and is also effective in preventing dripping of water, making the fog uniform and fine, and preventing danger caused by high-temperature water.

Further, since the water tank 6 is provided with the transparent mixing chamber cover 32 for covering the mixing chamber 24, the operator can visually check the spray outlet, so that the use of the high-temperature mixing chamber is not hindered. 24 can be prevented from being touched by hand by mistake and safety can be improved. (Embodiment 2) A second embodiment of the present invention will be described below with reference to FIG. Since the basic structure is the same as that of the conventional example, the same reference numerals are given and the description is omitted.

In FIG. 7, reference numeral 33 denotes a parallel tilt angle 15
Instead of the spray nozzle 28 spraying at a degree, a spray nozzle having a different spray angle at the top and bottom is used. This spray nozzle 33
As in the case of the spray nozzle 33 described in the first embodiment, the shape of the opening has a spread of 100 degrees in the horizontal direction, and the width in the height direction is the same as 1.5 mm at the thinnest portion.
Numeral 34 denotes an upper surface of the opening of the spray nozzle 33, which has an inclination of 20 degrees with respect to the horizontal direction. Similarly, 35 is the lower surface and 1
It has an inclination of 5 degrees.

The operation of the above configuration will be described. The mist atomized at once from the spray nozzle 33 is sprayed obliquely forward with a spread of 100 degrees in the horizontal direction and 1.5 mm in the vertical direction along with the shape of the spray nozzle along with the steam. At this time, the range in the front-rear direction of the spray is determined by the inclination angle of the upper surface 34 and the lower surface 35, so that the sprayed fog can be sprayed in the range of 15 degrees and 20 degrees while spreading in the vertical direction.

As a result, even without the tank end portion 31 described in the first embodiment, a fan-shaped range from the vicinity of the front end of the base 4 to about 150 mm ahead was obtained in the front-rear direction. It can be sprayed in the most convenient spray range. Further, by changing the angle, the spray range in the front-back direction can be freely determined.

According to the first aspect of the present invention, there is provided a water tank for storing water, a pump device provided in the water tank, and a vaporizer for vaporizing water in the water tank to generate steam. A base that forms a chamber, a first water conduit that guides water in the water tank to the vaporization chamber, a mixing chamber that granulates the water in the water tank by the flow rate of steam, and a water chamber in the water tank. A second water conduit for guiding the mixture to the mixing chamber, and a steam passage for guiding the steam generated in the vaporization chamber to the mixing chamber. A slit-shaped ejection nozzle is formed in the upper part of the side surface in the horizontal direction, so that the atomized mist can be spread in a fan shape and sprayed in the mixing chamber. In addition,
From the results of actual use experiments, it has been found from the results of actual use experiments that the optimum spraying range for effectively wetting the cloth should be widened to a substantially fan-shaped range from the vicinity of the iron tip to about 150 mm ahead from the iron tip. . The ejection nozzle of the present invention has a divergent angle of about 100 degrees and a slit shape with a thickness of about 1.5 mm, so that the mist ejected from the mixing chamber spreads in a fan shape and is sprayed. It has an optimal shape for spraying in the optimal spray range.

According to a second aspect of the present invention, in addition to the first aspect, the ejection nozzle has a shape in which the upper surface and the lower surface of the opening are inclined in the forward direction of the iron. In addition, it is possible to spray the iron in a predetermined spraying range while sliding the iron horizontally, without spraying the mist while holding the iron by hand and tilting the iron obliquely. According to a third aspect of the present invention, in addition to the second aspect, the inclination of the lower surface of the opening is made larger than the inclination of the upper surface without changing the cross-sectional area of the ejection nozzle. The spray range in the front-rear direction can be expanded without changing the diameter.

According to a fourth aspect of the present invention, in addition to the second aspect, the tip of the water tank extends to the front of the mixing chamber and extends along the lower surface of the jet nozzle. Since the mist spouted in a slit shape from the spout nozzle is spouted along the tank tip, the air in the slight gap between the two is pulled by the spray, resulting in a slight negative pressure. Then, the mist ejected at the inclination angle of the slit is ejected further inclined downward by the action of the downward force. Further, since the angle is proportional to the speed of the fog, initially, as the flow rate of the fog becomes faster and gradually slows down, the jetting angle of the fog initially spouts at a steep angle, but the angle gradually becomes gentler. This makes it possible to spread the mist finely in a slit shape in the width direction of the jet and to widen the spray range also in the front-back direction.

According to a fifth aspect of the present invention, in addition to the first aspect, the mixing chamber is formed in a substantially triangular prism shape, and one of the sharp ends thereof is disposed in front of the iron. With the configuration in which the ejection nozzle is formed at the upper portion thereof, compared to a cylindrical mixing chamber, the inside of the mixing chamber becomes tapered as it approaches the vicinity of the ejection nozzle,
As the passage cross section gradually decreases, and the water entering the mixing chamber does not disturb,
The mixture of water and steam can be reliably performed while being reliably pressed and crushed by the steam entering from behind.
And since it is opened to the atmosphere at the ejection nozzle portion where the passage cross-sectional area is the narrowest, it is opened to the atmosphere immediately after the pressure becomes highest, so that mist having a uniform particle size can be generated.

According to a sixth aspect of the present invention, in addition to the first aspect, the mixing chamber is formed in a substantially triangular prism shape, and a jet nozzle is positioned near the tip of the mixing chamber, and the bottom of the mixing chamber is ironed. By adopting a configuration that is inclined so as to become higher from the rear toward the ejection nozzle side, the inside of the mixing chamber becomes tapered as approaching the vicinity of the ejection nozzle as in claim 5, and the passage cross-sectional area gradually decreases. The water that has entered the mixing chamber can be reliably pressed by the steam that has entered from behind, causing it to be crushed. Since it returns to the vicinity of the steam passage located at the farthest position from, it can be surely crushed by the next spraying operation.

According to a seventh aspect of the present invention, in addition to the first aspect, a mixing chamber rib for partitioning the mixing chamber back and forth is provided, and the mixing chamber rib is provided along the bottom surface of the mixing chamber. It has a configuration in which an opening is formed below, and can prevent water sent into the mixing chamber from directly coming out of the jet nozzle before being crushed by steam. Further, since an opening is formed below the mixing chamber rib along the bottom surface of the mixing chamber, residual water does not remain. In addition, due to the effect of the ribs, the steam and water that hit the ribs rise in the mixing chamber, forming a constant vortex in the vertical direction, returning to the steam passage once again, and crushing with the subsequent steam, making the mist finer There is also an effect.

According to an eighth aspect of the present invention, in addition to the seventh aspect, the space partitioned by the mixing chamber ribs is configured such that the front space has a smaller volume than the rear space. Only the mist that is surely formed by this configuration is ejected from the ejection nozzle. According to a ninth aspect of the present invention, in addition to the seventh aspect, the opening area of the opening provided below the mixing chamber rib is larger than the opening area of the ejection nozzle. With this configuration, the size of the mist is further uniformed and the mist is sprayed.
