Description

[0001]
[Industrial applications]
The present invention relates to a shower apparatus provided with a cartridge for immersed particles in a shower room, a bathroom, a washbasin, and the like, and more particularly, to a structure of a cartridge for immersed particles containing immersed particles such as a desalinated material and a mineral dissolving material. .
[0002]
[Prior art]
For example, some hand shower devices have a cartridge for immersion granules in which immersion granules such as a desalting material, a deodorizing material, a decolorizing material, and a mineral eluting material for eluting various minerals in tap water are freely attachable. Are known. FIG. 5 is a longitudinal sectional view showing an example of the hand shower device. The hand shower apparatus shown in FIG. 5 has a shower head 10 having a shower jet surface S in which four grooved rings 1a to 1d are fitted adjacent to each other and the innermost ring 1a is fixed with screws 2, and a shower head. The gripping tube 20 includes a holding tube 20 which is screwed by fitting the packing 5 to the tube male screw portion 3 of the neck portion, and a shower hose 30 screwed to the tube male screw portion 21 of the holding tube 20. The gripping tube section 20 and the shower head 10 are detachable by unscrewing, and the tube space 22 of the gripping tube section 20 is configured so that the cartridge 40 for immersion particles shown in FIG. .
[0003]
The cartridge 40 for immersed granules is provided with a cylindrical cartridge case 42 having a mesh-shaped partition wall 41 that divides a pipeline space into two parts, and a claw fitting hole 42a formed at one open end of the cartridge case 42. The engagement claw 46b is fitted into the mesh cap 45 on the inflow side for closing the opening thereof and the claw fitting hole 42b formed on the other open end side of the cartridge case 42. A mesh cap 46 on the outflow side that engages and closes the opening thereof, and a relatively small grain desalinated material 47 packed in the pipe space between the mesh cap 45 on the inflow side and the mesh partition wall 41. And a relatively large mineral eluting material 48 packed in a tube space between the mesh-shaped partition wall 41 and the mesh cap 46 on the outflow side. An erroneous insertion preventing flange 42c is formed on the outer periphery of the cartridge case 42. When the outflow-side mesh-shaped cap 46 is inserted into the tube space 22 of the gripping tube 20, the flange 42c is attached to the gripping tube 20. And the cartridge 40 is incompletely dropped, so that an erroneous insertion operation can be recognized.
[0004]
When such a cartridge 40 for immersion granules is correctly loaded in the tube space 22 of the holding tube portion 20 and a shower device is used, tap water flows from the shower hose 30 in the direction of the arrow in FIG. 45, flows down the gap of the desalting material 47, passes through the mesh partition wall 41, flows through the gap of the mineral eluting material 48, is discharged from the mesh cap 46, and is showered from the shower ejection surface S as a shower. Gushing. For this reason, dissolved chlorine is removed from the shower water in a water bath by a desalting material 47, and the pH is adjusted by eluting an alkali component or the like by a mineral eluting material 48.
[0005]
[Problems to be solved by the invention]
However, the shower apparatus provided with the cartridge 40 for immersed particles shown in FIG. 6 has the following problems.
[0006]
{Circle around (1)} Since the desalting material is densely packed in the space filled with the relatively small (desirably 1 mm particle size) desalting material 47 in the cartridge case 42, the fluid resistance of the tap water increases, and therefore the water pressure on the downstream side is increased. And it is difficult to obtain a vigorous and comfortable shower pressure.
[0007]
{Circle around (2)} In order to reduce the fluid resistance, it is conceivable to reduce the resistance per unit area by shortening the thickness of the packed layer of the desalting material 47. However, the downstream portion (the mesh partition wall side) of the packed bed of the desalinated material 47 is densely packed with the fine desalinated material 47 by fluid pressure, and this dense portion is a flow path closed section. Therefore, since the fluid resistance is specified to be substantially high in this portion, it can not be said that reducing the filling of the desalting material 47 is not only effective in reducing the fluid resistance, but also the filling amount of the desalting material 47. The reduction itself leads to a decrease in dechlorination performance and a shortened life of replacement.
[0008]
SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to realize a shower apparatus including a cartridge for immersed particulate material that does not reduce the shower pressure unnecessarily and can prolong the life of replacement of the filler.
[0009]
[Means for Solving the Problems]
Means for Solving the Problems In order to solve the above-mentioned problems, the means taken by the present invention is characterized in that a basket for holding immersed granules for maintaining the form of the bulk of immersed granules is used. That is, the present invention relates to a shower device including a cartridge for immersed particles which is exchangeably loaded in a tube space of a gripping tube portion communicating with a shower head, wherein the cartridge for immersed particles is a cylindrical cartridge case and And a dipped granule holding cage which is housed so that it can be inserted into and removed from the cylindrical cartridge case. The dipped granule holding cage has a muzzle portion fitted on the inflow side of the cylindrical cartridge case, and gradually tapers from the muzzle portion to the tail. Characterized by the following streamline shape . Here, the basket is meant to include not only coarse meshes but also fine meshes capable of maintaining a streamline shape. The holding basket may be a resin molded product, or may be a net-attached basket surrounded by a net bag.
[0011]
It is desirable that a notch for preventing contact be formed in the mouth ring portion of the immersion particle holding cage. Further, it is desirable that a bottom raising leg is formed at the tail of the immersed grain holding cage.
[0012]
[Action]
When the shower device is used in such a state that the immersion granules are packed in such a streamlined immersion granule holding basket and then placed in a cylindrical cartridge case and loaded in the tube space of the gripping tube portion, the tap water is Although it flows down the gap between the immersed granules in the cartridge, since there is an unfilled securing area between the immersed granules and the case in the immersed granule holding cage, tap water flows from the center to the outer periphery in that part. The fluid resistance is low because it spreads and oozes out. Therefore, a decrease in water pressure is reduced on the downstream side, and a vigorous and comfortable shower pressure can be obtained. Further, since only the non-filling securing area is not filled with the immersion granules, the decrease in the filling amount is small in the whole ratio, which is not enough to lower the dechlorination performance and shorten the replacement life.
[0013]
In particular, in the present invention, since the notch for preventing contact is formed in the muzzle portion of the immersion granule holding cage, the mesh such as the mesh cap on the upstream side is not closed, and the non-contact area increases. Further, the fluid resistance can be further reduced.
[0014]
Further, since a bottom raising leg is formed at the tail of the immersed particulate material holding basket, a floor raising space can be secured, and tap water flows through the space. Therefore, it contributes to a reduction in fluid resistance.
[0015]
【Example】
Next, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1A is a longitudinal sectional view showing a cartridge case and a mesh-like cap of a cartridge for immersion granules used in a shower device according to an embodiment of the present invention, and FIG. 1B is a sectional view taken along line BB ′ of FIG. FIG. 3C is a cross-sectional view taken along the line, and FIG. 3C is a view taken along the line CC ′ in FIG.
[0017]
The outer housing structure of the cartridge 50 for immersed particulate material of the present example has a cylindrical cartridge case 52 having a mesh-like partition wall 51 that divides a pipe space into two parts, and one open end side of the cartridge case 52 at every 90 degrees. An engaging claw 55a is fitted into and engaged with the formed claw fitting hole 52a, and the mesh cap 55 on the inflow side for closing the opening is formed at the other open end side of the cartridge case 52 at intervals of 90 degrees. An engaging claw 55b is fitted into and engaged with the claw fitting hole 52b, and an outflow-side mesh cap 56 that closes the opening thereof. A desalted material storage portion 57 is provided between the mesh cap 55 on the inflow side and the mesh partition wall 51, and a mineral eluate material storage portion 58 is provided between the mesh partition wall 51 and the mesh cap 56 on the outflow side. ing. Incidentally, the outer periphery of the cartridge case 52 is inserted for preventing the flange 52c erroneous form, when inserted reticulated cap 56 side of the outlet side to the tube space 22 of the gripping tube 20 shown in FIG. 5, the flange 52 c abuts on the step of the opening of the gripping tube portion 20, the dropping of the cartridge 50 becomes incomplete, and an erroneous insertion operation can be recognized.
[0018]
In this example, the desalting material 47 and the mineral eluting material 48 are not directly filled in the desalting material storage portion 57 and the mineral eluting material storage portion 58, but a desalting material holding basket 60 as shown in FIG. And a cage 70 for holding a mineral-eluting material as shown in FIG. The desalting material holding basket 60 is a streamlined resin molded basket, and has a ring-shaped muzzle portion 61, a leg-shaped tail portion 62, and four vertical streaks tapering streamwise from the muzzle portion 61. The body 63 and ring-shaped band streaks 64 to 68 which define the thickness of the four vertical streaks 63 are integrally formed. The crown-shaped muzzle portion 61 is inserted into the claw fitting hole 52a of the engaging claw 55a of the mesh-shaped cap 55 on the inflow side and the retaining ring concave portion 61a into which a convex piece of a mesh bag retaining ring described later is fitted. Notch 61b is formed to allow for
[0019]
Four foot-raising legs 62a are integrally formed in the footrest-shaped tail portion 62, and a floor-raising space 62b is secured.
[0020]
The stitches of a semi-spindle-shaped basket composed of four longitudinal streaks 63 and five band streaks 64 to 68 are coarse, and filling the desalted material into the cage as shown in FIG. A mesh bag 80 is used. The desalinated material 47 is packed in the mesh bag 80, the mesh bag retaining ring 82 is put inside, and the bag mouth is tied with a thread 84. Such a desalted material bag is inserted into the desalted material holding basket 60. At this time, the projection 82a of the retaining ring 82 is fitted into the retaining ring recess 61a of the collar 61 of the cartridge case 60. Thereafter, as shown in FIG. 4, the desalting material holding basket 60 is placed in the desalting material storage portion 57 of the cartridge case 52, and the opening of the case 52 is closed with the cap 55.
[0021]
On the other hand, the mineral eluting material holding basket 70 is a streamlined resin molded basket as shown in FIG. 2B, and has a ring-shaped mouth ring 71, a footrest-shaped tail 72, and a mouth ring. Six vertical stripes 73 tapering streamlined from 71, and ring-shaped strips 74a to 74j that define the thickness of the six vertical stripes 73 are integrally formed. . The notch 71a is formed in the muzzle portion 71 to reduce the closed area of the mesh hole of the mesh partition wall 51. Six foot-raising legs 72a are integrally formed on the footrest-shaped tail 72, and a floor-raising space 72b is secured. Since such a mineral eluting material holding basket 70 has a fine stitch, it does not leak even if a relatively large (several mm or more) mineral eluting material 48 is directly filled. The mineral eluting material holding basket 70 is placed in the mineral eluting material storage part 58 of the cartridge case 52 as shown in FIG. 4, and then the cap 56 is closed with the opening of the case 52.
[0022]
When the cartridge 50 shown in FIG. 4 is correctly loaded into the tube space 22 of the gripping tube portion 20 shown in FIG. 5 and a shower device is used, tap water passes through the mesh of the mesh-shaped cap 55 from the shower hose 30 and mesh bags. Flows downward in the gap between the desalting material 47 in the inside, but since the cross-sectional area of the unfilled securing area 60a between the desalting material holding basket 60 and the case 52 increases toward the downstream side, As the fluid resistance decreases, the tap water spreads from the center to the outer periphery and oozes out in the direction of the arrow in the drawing to flow. Then, it passes through the mesh-like partition wall 51 and flows down the gap of the mineral eluting material 48, but also in the downstream side, the non-filling securing area 70 a between the mineral eluting material holding basket 70 and the case 52 is cut off. Since the area is increased, the fluid resistance decreases toward the downstream side, and the tap water spreads from the center to the outer circumference, seeps in the direction of the arrow in the drawing, flows, and is discharged from the mesh cap 56. Then, it is ejected from the shower ejection surface S as a shower.
[0023]
As described above, the average fluid resistance in the cross section of the flow path is reduced by the holding baskets 60 and 70 for maintaining the filling volume of the immersed granules in the storage sections 57 and 58 of the case 52 as they are located on the downstream side. As a result, a decrease in water pressure is reduced on the downstream side, and a vigorous and comfortable shower pressure can be obtained. The downstream portion of the packed bed of the desalinated material 47 is densely packed with fine desalinated material by fluid pressure, and the fluid resistance of this dense portion is high, but the unfilled securing area as a wider relief space Since 60a remains, the average fluid resistance of the flow path cross section does not increase. Further, although the desalting material is not filled only in the non-filling securing region 60a, the decrease in the filling amount is not remarkable as a whole ratio, and is not so large as to lower the dechlorination performance and shorten the replacement life. .
[0024]
In the present example, notches 61b and 71b are formed in the muzzle portions 61 and 71 of the baskets 60 and 70, and the closed area of the mesh of the mesh cap 55 and the mesh partition wall 51 on the upstream side is reduced as much as possible. It is designed to reduce. Fluid resistance can be reduced.
Further, raised legs 62a, 72a are formed in the tail-shaped tails 62, 72 of the baskets 60, 70, and the raised spaces 62b, 72b are secured. When the bottom raising spaces 62b, 72b are present, tap water flows through the spaces, and the closed area of the mesh of the mesh-like partition wall 51 and the mesh-like cap 56 on the downstream side is made as small as possible. This leads to a decrease in fluid resistance.
[0025]
In the above embodiment, the mesh bag 80 as a separate component is placed in the basket 60. However, a net-attached basket surrounded by an integral mesh bag may be formed by insert molding or the like.
[0026]
【The invention's effect】
As described above, the present invention is characterized in that a streamlined immersion granule holding basket is used to maintain the shape of the immersion granule filling volume. Therefore, the following effects are obtained.
[0027]
{Circle around (1)} Since there is an unfilled securing region between the immersed granules and the case in the immersed granules holding basket, the tap water spreads from the center to the outer periphery and oozes out, so that the fluid resistance Is low. Therefore, a decrease in water pressure is reduced on the downstream side, and a vigorous and comfortable shower pressure can be obtained. Further, since only the non-filling securing area is not filled with the immersion granules, the decrease in the filling amount is small in the whole ratio, which is not enough to lower the dechlorination performance and shorten the replacement life.
[0028]
{Circle around (2)} Since the notch for preventing contact is formed in the muzzle portion of the immersion granule holding basket, the mesh such as the mesh cap on the upstream side is not closed, and the non-contact area is increased, further increasing the non-contact area. Fluid resistance can be reduced.
[0029]
{Circle around (3)} Since a bottom raising leg is formed at the tail of the immersed granule holding cage, a bottom raising space can be secured, and tap water flows through this space. Therefore, it contributes to a reduction in fluid resistance.
