Problems to be solved by the invention

However, in such a steam nozzle, if the amount of high-temperature dew condensation water pushed out by the ejected steam flow is larger than the amount of dew condensation water that can be absorbed by the water absorbent, the dew condensation water cannot be completely absorbed by the water absorbent, and there is a possibility that relatively hot water droplets are ejected over the water absorbent.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a safe steam nozzle capable of reliably absorbing dew condensation water in a water absorbing body.

In the steam nozzle according to claim 5 of the present invention, in addition to any one of claims 1 to 4, the slit has a size that causes a capillary phenomenon.

ADVANTAGEOUS EFFECTS OF INVENTION

In the steam nozzle according to claim 1 of the present invention, since the dew condensation water generated in the narrowest portion of the steam passage flows down along the inner wall of the narrowest portion, is guided to the slit portion, and then reaches and is absorbed by the water absorbing body, the dew condensation water can be reliably guided to the water absorbing body, and the hot dew condensation water can be prevented from being vigorously sprayed and sprayed onto the face or the like. Further, since the amount of the condensed water guided to the water absorbent body by the slit portion increases, the water absorbent body can reliably absorb the condensed water even if the amount of the condensed water generated increases. Further, since the dew condensation water can be retained even in the slit portion, it is possible to more reliably suppress the hot dew condensation water from being discharged.

Further, the narrowest portion of the steam path is formed by a cylindrical sleeve, and the slit portion is formed in the sleeve, so that the slit portion with a small gap size can be easily formed.

Further, since the slit portion has a slit shape, the dew condensation water guided to the slit portion along the inner wall of the narrowest portion can efficiently be guided to the water guide portion of the water guide body, and therefore the dew condensation water can be reliably guided to the water absorbing body.

Further, the slit portion has a concave shape, so that the strength of the narrowest portion can be maintained and the condensed water can be guided from the water guide portion of the water guide body to the water absorbing body.

Further, the slit is sized to cause a capillary phenomenon, so that the condensed water guided to the slit can be reliably guided to the water absorbent.

Detailed Description

Hereinafter, a first embodiment of the present invention will be described with reference to fig. 1 to 3. In the present embodiment, the left side of fig. 2 (a) is defined as the front side, and the right side is defined as the rear side. 1 is the steam nozzle of the present invention. The steam nozzle 1 includes a nozzle body 2, a sleeve 3, a water guide 4, a water absorbing body 5, and a steam pipe 6. The steam pipe 6 is connected to a steam generation unit, not shown. The steam generated by the steam generating means is discharged through a steam passage P provided in the steam nozzle 1.

The nozzle body 2 is formed of a synthetic resin. The nozzle body 2 includes a rear small-diameter portion 7, a front large-diameter portion 8, and a stepped portion 9 provided between the small-diameter portion 7 and the large-diameter portion 8. The small diameter portion 7 is formed in a short cylindrical shape with both ends open in the axial direction. A flange-like positioning rib 10 is formed on the inner surface of the small diameter portion 7. Further, slit-shaped notches 11 are formed as slit portions in the lower portions of the positioning ribs 10. In the present invention, the slit shape shows a completely separated state. That is, the positioning rib 10 is divided in the axial direction by the notch 11. Further, a steam through hole 12 is formed in the center of the positioning rib 10. That is, the notch 11 is continuous with the through hole 12. The large diameter portion 8 is formed in a short cylindrical shape having a diameter larger than that of the small diameter portion 7 and having both ends open in the axial direction. The tip of the large diameter portion 8 serves as an ejection port 13. The stepped portion 9 is formed to protrude outward from the front end of the small diameter portion 7 and inward in a flange shape from the rear end of the large diameter portion 8.

The sleeve 3 is formed of a metal such as brass, is formed in a substantially cylindrical shape with both ends open in the axial direction, and is inserted into the small diameter portion 7. The rear end of the sleeve 3 abuts against the positioning rib 10 and is positioned. In this state, the tip end of the sleeve 3 is located at substantially the same position as the tip end of the small diameter portion 7. A slit-shaped notch 14 is formed as a slit portion in a lower portion of the sleeve 3. That is, the sleeve 3 is divided in the axial direction by slit-shaped notch portions 11, and as shown in fig. 2 (b), has a C-shaped cross section perpendicular to the axis. Further, a through hole 15 is formed in the center of the sleeve 3 in the axial direction. That is, the notch 14 is connected to the through hole 15. The diameter of the through hole 12 of the positioning rib 10 is substantially the same as the diameter of the through hole 15 of the sleeve 3. Therefore, the positions of the through

holes

12 and 15 are the narrowest portions 16 of the steam passages P. The notch 11 of the positioning rib 10 communicates with the notch 14 of the sleeve 3.

The water guide 4 is installed to pass through the steam path P. The water guide 4 is formed by bending one wire having a smaller inner diameter than the through hole 15 of the sleeve 3, that is, the narrowest portion 16. Therefore, the water guide 4 is easily and inexpensively formed. As shown in fig. 2 (a) and 3, the water guide 4 includes: a linear first water guide 17 substantially parallel to the axial direction of the steam passage P; a linear second water conveying part 18 formed at the outlet side of the first water conveying part 17 so as to be bent downward in a direction perpendicular to the axis; a straight backwater portion 19 formed at an inlet side of the first water guide portion 17 to be bent downward; and an annular portion 20 extending from a tip end portion of the second water conveying portion 18 around the axis of the steam passage P. The first water conveying part 17 is disposed parallel to the

notch parts

11 and 14. The second water conveying part 18 is arranged parallel to the cutout part 14.

The water absorbing body 5 is formed in a ring shape from a water absorbing material such as felt, and is inserted inside the large diameter portion 8 and in front of the stepped portion 9. The water absorbing body 5 is formed to have an outer diameter substantially equal to the inner diameter of the large diameter portion 8. The water absorbing body 5 is formed to have an inner diameter larger than that of the small diameter portion 7.

The steam pipe 6 is made of a material having heat resistance and flexibility, such as silicone rubber. As described above, the steam pipe 6 has heat resistance and flexibility, and can pass high-temperature steam and change the direction of the steam nozzle 1.

Next, the operation of the present embodiment will be described. First, steam is generated by a steam generation unit, not shown, and the generated steam is sent to the steam passage P. The steam passes through the through-hole 12 of the nozzle body 2 and the through-hole 15 of the liner 3 from the steam pipe 6, and then is jetted from the jet port 13 of the steam nozzle 1 in the direction of the central axis of the steam passage P.

When steam is continuously injected from the steam nozzle 1, the steam is condensed in the steam passage P, and high-temperature liquid dew condensation water is generated. Further, if a large number of water droplets of the condensed water are combined, the water droplets may become large and may be pushed out by the steam flow. However, since the first water conducting portion 17 of the water conducting body 4 is located close to the lower side of the inner peripheral surface of the through hole 12 of the positioning rib 10 as the narrowest portion 16 and the lower side of the inner peripheral surface of the through hole 15 of the sleeve 3 as the narrowest portion 16, water droplets flowing down along the inner peripheral surfaces of the through

holes

12 and 15 by gravity are sucked and held in a wide range by a minute gap formed by the edge of the

notch portions

11 and 14 and the first water conducting portion 17 by capillary action. Further, the dew condensation water is also sucked and held by the notch 11 of the positioning rib 10 and the notch 14 of the sleeve 3 by utilizing the capillary phenomenon. In this state, the flow area of the steam passage P (the flow area of the through holes 12 and 15) is not substantially reduced by the dew condensation water, and the dew condensation water is not pushed out by the steam flow violently. When the condensed water further flows down and is accumulated in the slit, the accumulated condensed water is pushed by the steam flow and is pushed out from the slit. The pushed-out dew condensation water comes into contact with the first water conduit 17 and moves outward from the distal end portion of the liner 3 (narrowest portion 16) along the first water conduit 17. The dew condensation water moving to the outside along the first water guide 17 flows downward, that is, toward the water absorbent body 5 along the second water guide 18 integrated with the first water guide 17. The dew condensation water flowing along the second water conduit 18 is absorbed by the water absorbent 5 in contact with the second water conduit 18. Thus, the dew condensation water is sent to the water absorbing body 5 along the water guide body 4, and the hot dew condensation water can be prevented from being vigorously discharged from the discharge port 13 of the steam nozzle 1 and being discharged to the face or the like.

The condensed water can be sent to the water absorbent 5 through the

cut portions

11 and 14. In this case, the dew condensation water can be sent to the water absorbent body 5 through the cut-out

portions

11 and 14, not only through the minute gaps between the edges of the cut-out

portions

11 and 14 and the first water guide 17, and the water absorbent body 5 can efficiently absorb the dew condensation water. As a result, the dew condensation water can be more reliably prevented from being discharged from the discharge port 13 of the steam nozzle 1.

When the water absorbing body 5 exceeds the limit of the water absorbing capacity, the condensed water that is not completely absorbed may be discharged from the discharge port 13 as water droplets. However, since the dew condensation water is sucked and held by the

cut portions

11 and 14 as described above, if the water absorbing body 5 exceeds the limit of the water absorbing capacity, the dew condensation water which is not completely absorbed is accumulated in the

cut portions

11 and 14. When the amount of the condensed water exceeds the amount of water that can be retained in the

notches

11 and 14, the condensed water returns to the steam pipe 6 through the notch 11. The steam passage P is a narrowest portion 16 at the position of the positioning rib 10 and the sleeve 3, that is, the narrowest portion 16 has a stepwise decreasing flow area, so that water droplets upstream of the narrowest portion 16 are not ejected from the ejection port 13 through the narrowest portion 16. The condensed water accumulated in the minute gap between the edge of the

notch

11 or 14 and the first water guide 17 is returned to the steam pipe 6 along the first water guide 17 and the water return portion 19. At this time, since the water returning part 19 is bent downward as described above, the water droplets of the condensed water can be reliably returned into the steam pipe 6 by gravity.

As described above, the steam nozzle 1 of the present invention includes the nozzle body 2, the water absorbing body 5 provided on the outlet side of the narrowest part 16 of the steam passage P in the nozzle body 2, and the water guiding body 4 provided with the water guiding part for guiding dew condensation water from the narrowest part 16 of the steam passage P to the water absorbing body 5, wherein the water guiding body 4 is formed by bending a metal wire thinner than the inner diameter of the narrowest part 16, the water guiding part includes the first water guiding part 17 and the second water guiding part 18, the first water guiding part 17 is arranged parallel to the steam passage P along the part of the inner circumferential surface of the steam passage P that becomes the lower side in use, the second water guiding part 18 is arranged to extend from the outlet of the narrowest part 16 of the steam passage P in the direction that becomes the lower side in use, and in the steam nozzle 1, the part of the inner circumferential surface of the narrowest part 16 that becomes the lower side in use is provided with the slit-like slit-shaped water guiding part 11, and the slit-like, 14 and water guides 17 and 18 of the water guide 4 are provided in the vicinity of the notches 11 and 14, so that dew condensation water generated in the narrowest portion 16 of the steam passage P flows down along the inner wall of the narrowest portion 16, is guided to the notches 11 and 14, then reaches the water absorbent 5 and is absorbed by the water absorbent 5, and therefore dew condensation water can be reliably guided to the water absorbent 5, and further, it is possible to suppress the hot dew condensation water from being vigorously sprayed and sprayed onto the face or the like. Further, since the amount of the condensed water guided to the water absorbent 5 by the

notches

11 and 14 increases, the water absorbent 5 can reliably absorb the condensed water even if the amount of the condensed water generated increases. Further, since the dew condensation water can be retained even in the

notches

11 and 14, the ejection of the hot dew condensation water can be more reliably suppressed.

In the present invention, the narrowest portion 16 of the steam path is formed by the tubular sleeve 3, and the cut-out portion 14 is formed as a slit portion in the sleeve 3, so that the cut-out portion 14 having a small gap size can be easily formed.

In the present invention, since the cut portion 14 has a slit shape, the dew condensation water guided to the cut portion 14 along the inner wall of the narrowest portion 16 can efficiently be guided to the water guides 17 and 18 of the water guide 4, and therefore the dew condensation water can be reliably guided to the water absorber 5.

In the present invention, the cut-out portion 14 is sized to cause a capillary phenomenon, so that the condensed water guided to the cut-out portion 14 can be reliably guided to the water absorbent body 5.

Next, a second embodiment of the present invention will be described with reference to fig. 4 and 5. In the present embodiment, the left side of fig. 5 (a) is defined as the front side, and the right side is defined as the rear side. 21 is the steam nozzle of the present invention. The steam nozzle 21 includes a nozzle main body 22, a sleeve 23, a water guide 4, a water absorbing body 5, and a steam pipe 6. The steam pipe 6 is connected to a steam generation unit, not shown. The steam generated by the steam generating unit is discharged through a steam passage P' provided in the steam nozzle 21.

The nozzle body 22 is made of synthetic resin. The nozzle body 22 includes a rear small-diameter portion 27, a front large-diameter portion 28, and a stepped portion 29 provided between the small-diameter portion 27 and the large-diameter portion 28. The small diameter portion 27 is formed in a short cylindrical shape with both ends open in the axial direction. A flange-like positioning rib 30 is formed on the inner surface of the small diameter portion 27. Further, a recessed groove portion 31 as a slit portion is formed in a lower portion of the positioning rib 30. The concave shape described here is a shape that is partially continuous and concave, unlike the slit shape of the first embodiment. That is, a portion of the positioning rib 30 is connected at a lower portion thereof. Further, a steam through hole 32 is formed in the center of the positioning rib 30. The groove 31 is connected to the through hole 32. The large diameter portion 28 is formed in a short cylindrical shape having a diameter larger than that of the small diameter portion 27 and having both ends open in the axial direction. The tip of the large diameter portion 28 serves as an ejection port 33. The stepped portion 29 is formed to protrude outward from the front end of the small diameter portion 27 and inward from the rear end of the large diameter portion 28 in a flange shape.

The sleeve 23 is formed of a metal such as brass, is formed in a substantially cylindrical shape with both ends open in the axial direction, and is inserted into the small diameter portion 27. The rear end of the sleeve 23 abuts against the positioning rib 30 and is positioned. In this state, the tip of the sleeve 23 is located at substantially the same position as the tip of the small diameter portion 27. A concave groove portion 34 as a slit portion is formed in a lower portion of the inner surface of the sleeve 23. The groove 34 is formed parallel to the axial direction of the sleeve 23. Further, unlike the first embodiment, the sleeve 23 is partially continuous on the outer peripheral side of the groove 34. Further, a through hole 35 is formed in the center of the sleeve 23 in the axial direction. That is, the groove 34 is connected to the through hole 35. The diameter of the through hole 32 of the positioning rib 30 is substantially the same as the diameter of the through hole 35 of the sleeve 23. Therefore, the positions of the through

holes

32 and 35 are the narrowest parts 36 of the steam passages P'. The groove 31 of the positioning rib 30 communicates with the groove 34 of the sleeve 32.

The water guide 4 is installed to pass through the steam path P'. The water guide 4 is formed by bending one wire having a smaller inner diameter than the through hole 35 of the sleeve 23, that is, the narrowest portion 36. Therefore, the water guide 4 is easily and inexpensively formed. The water guide body 4 is configured to include: a linear first water guide 17 substantially parallel to the axial direction of the steam passage P'; a linear second water conveying part 18 formed at the outlet side of the first water conveying part 17 so as to be bent downward in a direction perpendicular to the axis; a straight backwater portion 19 formed at an inlet side of the first water guide portion 17 to be bent downward; and an annular portion 20 extending from a tip end portion of the second water conveying portion 18 around the axis of the steam passage P. The first water conveying part 17 is arranged parallel to the

grooves

31 and 34. The second water conveying part 18 is arranged parallel to the groove 34.

The water absorbing body 5 is formed in a ring shape from a water absorbing material such as felt, and is inserted inside the large diameter portion 28 and in front of the stepped portion 29. The water absorbing body 5 is formed to have an outer diameter substantially equal to the inner diameter of the large diameter portion 28. The water absorbing body 5 is formed to have an inner diameter larger than that of the small diameter portion 27.

The steam pipe 6 is made of a material having heat resistance and flexibility, such as silicone rubber. As described above, the steam pipe 6 has heat resistance and flexibility, and can pass high-temperature steam and change the direction of the steam nozzle 21.

Next, the operation of the present embodiment will be described. First, steam is generated by a steam generation unit, not shown, and the generated steam is sent to the steam passage P'. The steam passes through the through-hole 32 of the nozzle body 22 and the through-hole 35 of the sleeve 33 from the steam pipe 6, and then is jetted from the jet port 33 of the steam nozzle 21 in the direction of the central axis of the steam passage P'.

When the steam is continuously injected from the steam nozzle 1, the steam is condensed in the steam passage P', and high-temperature liquid dew condensation water is generated. Further, if a large number of water droplets of the condensed water are combined, the water droplets may become large and may be pushed out by the steam flow. However, since the first water conducting part 17 of the water conducting body 4 is located close to the lower side of the inner peripheral surface of the through hole 32 of the positioning rib 30 as the narrowest part 36 and the lower side of the inner peripheral surface of the through hole 35 of the sleeve 23 as the narrowest part 36, water droplets flowing down along the inner peripheral surfaces of the through

holes

32 and 35 by gravity are sucked and held in a wide range by a minute gap formed by the edge of the

groove parts

31 and 34 and the first water conducting part 17 by capillary action. Further, the dew condensation water is also sucked and held by the groove portion 31 of the positioning rib 30 and the groove portion 34 of the sleeve 23 by utilizing the capillary phenomenon. In this state, the flow area of the steam passage P' (the flow area of the through holes 32 and 35) is not substantially reduced by the dew condensation water, and the dew condensation water is not strongly pushed out by the steam flow. When the condensed water further flows down and is accumulated in the slit, the accumulated condensed water is pushed by the steam flow and is pushed out from the slit. The pushed-out dew condensation water comes into contact with the first water conduit 17 and moves outward from the distal end portion of the sleeve 23 (narrowest portion 36) along the first water conduit 17. The dew condensation water moving to the outside along the first water guide 17 flows downward, that is, toward the water absorbent body 5 along the second water guide 18 integrated with the first water guide 17. The dew condensation water flowing along the second water conduit 18 is absorbed by the water absorbent 5 in contact with the second water conduit 18. Thus, the dew condensation water is sent to the water absorbing body 5 along the water guide body 4, and the hot dew condensation water can be prevented from being vigorously discharged from the discharge port 33 of the steam nozzle 21 and being discharged to the face or the like.

The condensed water can be sent to the water absorbent 5 through the

grooves

31 and 34. In this case, dew condensation water can be sent to the water absorbent body 5 via the

groove portions

31 and 34, not only in a minute gap between the edge of the

groove portions

31 and 34 and the first water guide 17, and dew condensation water can be efficiently absorbed by the water absorbent body 5. As a result, the dew condensation water can be more reliably prevented from being discharged from the discharge port 33 of the steam nozzle 21.

When the water absorbing body 5 exceeds the limit of the water absorbing capacity, the incompletely absorbed condensed water may be formed into water droplets and may be ejected from the ejection port 33. However, since the dew condensation water is sucked and held by the

grooves

31 and 34 as described above, if the water-absorbing body 5 exceeds the limit of the water-absorbing capacity, the dew condensation water which is not completely absorbed is accumulated in the

grooves

31 and 34. When the amount of water exceeds the amount that can be held in the

grooves

31 and 34, the dew condensation water returns to the steam pipe 6 through the grooves 31. The steam passage P' has a narrowest portion 36 at the position of the positioning rib 30 and the sleeve 23, that is, the flow area is reduced in a stepwise manner at the narrowest portion 36, so that water droplets upstream of the narrowest portion 36 are not ejected from the ejection port 33 through the narrowest portion 36. The dew condensation water accumulated in the minute gap between the edge of the

groove

31 or 34 and the first water guide 17 is returned to the steam pipe 6 along the first water guide 17 and the water return 19. At this time, since the water returning part 19 is bent downward as described above, the water droplets of the condensed water can be reliably returned into the steam pipe 6 by gravity.

As described above, the steam nozzle 21 of the present invention includes the nozzle body 22, the water absorbing body 5 provided on the outlet side of the narrowest part 36 of the steam passage P ' in the nozzle body 22, and the water guide body 4 provided with the water guide part for guiding the dew condensation water from the narrowest part 36 of the steam passage P ' to the water absorbing body 5, wherein the water guide body 4 is formed by bending a metal wire thinner than the inner diameter of the narrowest part 36, the water guide part includes the first water guide part 17 and the second water guide part 18, the first water guide part 17 is arranged parallel to the steam passage P ' along the part of the inner peripheral surface of the steam passage P ' which becomes the lower side in use, the second water guide part 18 is arranged to extend from the outlet of the narrowest part 36 of the steam passage P ' in the direction which becomes the lower side in use, and the steam nozzle 21 is provided with the concave groove part 31, which is a slit part, at the part of the inner peripheral surface of the narrowest part 36 which becomes the lower side in use, 34 and water guides 17 and 18 of the water guide 4 are provided in the vicinity of the grooves 31 and 34, so that the dew condensation water generated in the narrowest part 36 of the steam passage P' flows down along the inner wall of the narrowest part 36, is guided to the grooves 31 and 34, then reaches the water absorbent 5, and is absorbed by the water absorbent 5, whereby the dew condensation water can be reliably guided to the water absorbent 5, and further, the hot dew condensation water can be prevented from being vigorously sprayed and sprayed on the face or the like. Further, since the amount of the dew condensation water guided to the water absorbent body 5 by the

groove portions

31 and 34 increases, even if the amount of the dew condensation water generated increases, the water absorbent body 5 can reliably absorb the dew condensation water. Further, since the dew condensation water can be retained in the

grooves

31 and 34, the ejection of the hot dew condensation water can be more reliably suppressed.

In the present invention, the narrowest portion 36 of the steam passage is formed by the cylindrical sleeve 23, and the groove 34 as a slit portion is formed in the sleeve 23, so that the groove 34 with a small gap dimension can be easily formed.

In the present invention, the groove 34 has a concave shape, so that the dew condensation water can be guided from the

water guide portions

17 and 18 of the water guide 4 to the water absorbent 5 while maintaining the strength of the narrowest portion 36.

In the present invention, the groove 34 is dimensioned to cause a capillary phenomenon, so that the dew condensation water guided to the groove 34 can be reliably guided to the water absorbent body 5.

The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the present invention. For example, in the above embodiments, the notch or groove as the slit is a simple slit or groove shape, but may be a shape capable of sucking and holding dew condensation water, and the sectional shape thereof may be freely set within a range satisfying the condition.
