Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention provides a massager by adjusting the strength of the water spouted from the shower head. The present invention relates to a shower device that performs a shower function.

0002

[Conventional technology]

Traditionally, water spewing from a shower head has been made intermittently to control the strength and weakness of the water. A massage salon with a is being used. For example, a common example is JP-A-59-15 There is one described in the 1958 publication. This is installed at the water spout end of the shower head. Arrange multiple spout holes in a ring on the water sprinkling plate, close these spout holes one by one, and then open them again. A rotor like this is built into the shower head. Rotor is supplied It is like a water wheel that is forced to rotate by the water that flows through it, and its rotation causes Water in the shower head is spouted intermittently by opening and closing the water spout intermittently. do.

0003 According to this type of intermittent water sprinkling, compared to shower water sprinkling with uniform strength, As water hits the body intermittently, it gives the muscles a sense of the strength of the water being spewed out. You can get a massage effect.

0004

[Problem that the idea aims to solve]

In other words, intermittent water spouting for massage means that water is once poured into the shower head. In addition to the method of storing water and releasing it all at once when the water discharge hole opens according to the rotation of the rotor. It won't happen. Then, the water from the spout becomes a big lump and shoots out. Most of the massage functions are performed by applying this mass to the body.

[0005] However, when large bodies of water are released strongly intermittently, they can hit the body. The water splashes and scatters violently after washing. For this reason, when applying it to your shoulders or neck, Water splashes easily on your face, which makes it difficult to use, and the water splashes out more than necessary. turn into. Also, if the flow rate is too large, a mass of water from the spout may hit your body. The strength of the barrel also increases, resulting in pain. For this reason, the flow rate You have to be careful with the adjustment, and the usability is not perfect.

[0006] In this way, traditional massage showers use water or hot water directly from the source. Since water is only spouted intermittently, problems such as splashing water and flow rate adjustment remain, as well as problems with optimal There is also an upper limit to the effectiveness of massage.

[0007] The problem to be solved with this invention is to provide a comfortable massage with less water splashing. The idea is to make it easy.

[0008]

[Means to solve the problem]

The present invention includes a main body formed with an internal flow path that communicates with a water supply source, and a body that communicates with the internal flow path. and a plurality of water sprinkling holes that open at the water spouting end, and a flow path from the internal flow path to the water sprinkling holes. The shower device is equipped with a mechanism for intermittently opening and closing the shower according to the flow of water supply, A foaming chamber for foaming the supplied water is provided in the middle of the flow path toward the water hole, and the foaming chamber The oxidation chamber has a depressurizing effect due to the acceleration of the flow from the internal flow path toward the watering holes.

【Example】 Figure 1 is a longitudinal sectional view of the shower head of the massage shower device of the present invention, and Figure 2 is FIG.

[0011] In the figure, the shower head has a main body 1 that communicates with a water supply source, and a shower head that is built into the main body 1. It is composed of a sleeve 2 of different diameters and a water sprinkling plate 3 fixed to the discharge end of the main body 1. There is.

0012 The different diameter sleeve 2 is assembled with the small diameter part of the upper half facing the internal flow path 1a of the main body 1. It is integrated into the main body 1 with its lower end restrained by a sprinkler plate 3. So The small diameter portion of the different diameter sleeve 2 is provided with a swirl for swirling the water that has flowed into the main body 1. A circulating flow chamber 4 is provided, and the large diameter portion in the lower half converts water from the swirling flow chamber 4 into foam. A foaming chamber 5 is provided for this purpose.

[0013] 3 is a schematic cross-sectional view taken along line A-A in FIG. 1, and the swirling flow chamber 4 is circular. A total of four inlet holes 4a are formed in the peripheral wall of the inlet hole 4a, which has a shaped cross section, and is located approximately in the center of the bottom wall. The discharge hole 4b is opened. The inflow hole 4a is taut to the inner circumferential wall of the swirling flow chamber 4. The inner wall of the main body 1 and the different diameter The water from the annular internal flow path 1a between the ribs 2 flows into the swirling flow channel as shown by the arrow in the figure. The flow flows into the bar 4, and then the flow is forced to turn in a clockwise direction. I am made to do so. In addition, the opening area of the discharge hole 4b is the sum of the opening area of the four inlet holes 4a. If it is made smaller, water will stay in the swirling flow chamber 4, and the internal pressure will also decrease. rises somewhat. Therefore, in the swirling flow chamber 4, the flow energy of the water itself is centrifugal force due to swirling flow acts. Therefore, it is released from the release hole 4b. Water spreads outward under the influence of centrifugal force, forming a conical shape as shown by the broken line in Figure 1. It is discharged as a water film.

[0014] The swirling flow chamber 5 has a cylindrical shape with an open bottom end and is coaxial with the discharge hole 4b. A female thread 5a is formed on the peripheral wall to promote foaming of water from the discharge hole 4b. Ru. This female screw 5a uses its unevenness to reflect water from the discharge hole 4b at various angles. To promote turbulence by letting the air radiate, and to facilitate the mixing of suction air, which will be described later. The purpose is to

[0015] The water sprinkling plate 3 is fixed to the lower end of the main body 1, and is used for spraying foamy water as shown in Fig. 2. A plurality of water sprinkling holes 6 are arranged in an annular manner, and a foaming channel is provided in the center to supply air for foaming. An air hole 7 for suction is opened in the bar 5. Inside each water sprinkling hole 6, foamy water is rectified. A rectifier plate 6a having a cross-shaped cross section for discharging the liquid is incorporated in each of the rectifying plates 6a. Ru. In addition, a truncated conical guide 8 is integrated on the top surface of the water sprinkling plate 3 coaxially with the air hole 7. An air suction cylinder 9 is connected to this guide 8, and water is spouted from each water sprinkling hole 6. A block 10 for intermittent operation is rotatably attached to the air suction cylinder 9.

[0016] FIG. 4 shows the upper surface of the water spray plate 3 and the block 1 included in the foaming chamber 5. FIG. On the top surface of the sprinkler plate 3, there is a A plurality of divided rectifier plates 3a are arranged radially, and a height higher than this divided rectifier plate 3a is A semi-annular current plate 3b is provided. In the example of FIG. The annular rectifying plate 3b is arranged so as to pass through the holes 6, and the annular current plate 3b passes approximately through the center of the water sprinkling holes 6. It is built in as a circular shape. The divided rectifying plate 3a is a foaming chamber. It functions to evenly distribute the water that has become foamy in the tube 5 to each watering hole 6, and creates an annular rectifier. The plate 3b is for the water sprinkling holes 6 to evenly distribute the flow to the center and outside of the water sprinkling plate 3. It is. In addition, the divided rectifier plate 3a is arranged so that it passes through the center of each water sprinkling hole 6, as shown in FIG. It may be an array. In addition, on the upper end side of the air suction cylinder 9, there is a foaming chamber 5. Backflow prevention that prevents foamed water from flowing back from the discharge hole 4b to the swirling flow chamber 4 side A stop plate 9a is provided.

[0017] The block 10 is fitted into the upper end of the air suction tube 9, and its lower surface is connected to the backflow prevention plate 9. Fig. 5(a) shows the plan view and Fig. 5(b) shows the plan view. A longitudinal cross-sectional view is shown. The block 10 has a disk-shaped flange 10a at its lower end. An annular wall 10b is coaxially formed on the upper surface, and a hollow is formed in contact with the inner wall of the annular wall 10b. A mounting seat 10c into which the air suction cylinder 9 is inserted is provided. And this block 10 As shown in Fig. 1, insert the air suction cylinder 9 into the mounting seat 10c and attach the flange 10a. is mounted on the backflow prevention plate 9a and is rotatable around the air suction tube 9. . That is, the block 10 rotates about the mounting seat 10c as an eccentric axis, as shown in FIG. The diameter of the flange 10a is such that it covers the entirety of at least one water spray hole 6. It has a degree of magnitude.

[0018] In the above configuration, when water is supplied to the main body 1 of the shower head, water flows through the internal flow path 1. a into the swirling flow chamber 4. Then, as mentioned above, this swirling flow When water is forcibly swirled in the chamber 4 and then released from the discharge hole 4b, it forms a conical shape. The water becomes a film of water and is supplied to the water sprinkling plate 3 side at a high flow rate. At this time, the flow of the water film As the speed increases, the pressure in the space around the upper end of the air suction cylinder 9 decreases, which causes the external Air enters the foaming chamber 5 through the air suction cylinder 9 from the air hole 7 that is open to the It gets sucked in. Therefore, the foam is discharged from the discharge hole 4b at high speed into the foaming chamber 5. Air is mixed into the water broken by the female screw 5a on the wall, and the water supply becomes foamy. Ru.

[0019] On the other hand, the water discharged from the discharge hole 4b is subjected to forced swirling inside the swirling flow chamber 4. Depending on the flow history of the rotation, the water that exits the discharge hole 4b also tends to flow in this swirling direction. affected by the flow energy. For this reason, the swirling flow chamber 4 shown in FIG. The field of flow in the same direction as the flow in the direction of the arrow in the foaming chamber 5 is as shown in FIG. It also occurs in water that has just flowed into it. And the block 10 is the flange 1 Since it is bowl-shaped with an annular wall 10b on the top surface of 0a, the concave area surrounded by this annular wall 10b is When the water flows in, leaving a flow component in the swirling direction, the inner wall of the annular wall 10b moves against the water wheel. The block 10 acts like a blade, and as a result, the block 10 rotates the air suction tube 9 in FIG. It is rotated in the direction of the arrow as the center of rotation.

[0020] At the same time as the block 10 is rotated by the water from the discharge hole 4b, Then, the feed water is foamed in the foaming chamber 5. And block 10 is shown in FIG. As shown in FIG. , the flow to the water sprinkling hole 6 covered by the flange 10a of the block 10 is temporarily obstructed. Ru. Therefore, if the flow rate of water from the discharge hole 4b is sufficient, foaming will occur at the same time. By forced rotation of the block 10, the annularly arranged watering holes 6 discharge water in this arrangement order. The water discharge is stopped intermittently. For this reason, one water sprinkling hole 6 has foamy water. Intermittent water spouting is performed, and by using the entire water sprinkling hole 6, the strength of the foamy water can be adjusted. You can get a massage shower.

[0021] In this way, the shower water that is spouted intermittently is foamy water, so it is Compared to when the mass is released all at once, the degree of water splash after hitting the body is small. It becomes. For this reason, even when taking a shower, water splashes onto your face, such as on your shoulders and neck. This makes it easier to use. In addition, since foamy water contains air bubbles, Even if it is released as a lump from 6, it will give a softer feel to the human skin compared to a lump of water only. give. For this reason, even if the flow rate is too high, you will not feel any pain, and User-friendliness is improved as there is no need to worry about adjusting the amount. Furthermore, foamy water contains air bubbles. Therefore, it is expected that the cleaning power will be improved due to the turbulent flow after it hits the skin.

[0022] 7 to 9 show other examples of the block 10, and (a ) shows a plan view, and (b) shows a longitudinal sectional view.

[0023] In the example of FIG. 7, a single blade is used instead of the annular wall 10b formed on the flange 10a. 10d is raised in the radial direction so as to pass through the core of the mounting seat 10c. Ma In addition, the one in FIG. 8 has a plurality of radial blades 10e erected around the mounting seat 10c. This is an example. Furthermore, the one in FIG. 9 is rotatably assembled on the outer periphery of the backflow prevention plate 9a. An annular mounting tube 10f is provided coaxially with the flange 10a. Then, the inner periphery of the lower end thereof is rotatably connected to the outer periphery of the backflow prevention plate 9a. In addition, For this connecting structure, a groove is cut all around the inner circumferential wall of the mounting tube 10f, and a What is necessary is just to fit the edge of the backflow prevention plate 9a. Also, the outside of the mounting tube 10f One blade of 10g is raised on the side, and when attached to the backflow prevention plate 9a, the flange The positions of the flange 10a and the mounting tube 10f are eccentric so that the flange 10a is eccentric. Ru.

[0024] In any of these blocks 10, the blades 10d and the airfoils are When water hits the radial blades 10e and 10g, the block 10 is forced to The water spray holes 6 can be rotated intermittently to enable intermittent spouting of water from each water sprinkling hole 6. Note that the structure in Figure 9 In this case, the blade 10g is not necessarily necessary, and the water hitting the mounting tube 10f The block 10 can be rotated using force.

[0025] FIG. 10 is a longitudinal cross-sectional view of a shower head showing another embodiment, which shows It is also possible to have a structure in which water is intermittently supplied to each watering hole and turned into foam before the water is sprayed. It is.

[0026] In the figure, a water sprinkling head 12 is integrated on the bottom surface of the main body 11 of the shower head. At the same time, the main body 11 is formed with an internal flow path 11a that communicates with a water supply source. watering Inside the head 12, a plurality of foaming chambers 13 are arranged independently in a ring shape. A water sprinkling hole 14 is coaxially formed at the lower end of each foaming chamber 13. ing. A fine mesh is placed at the boundary between the foaming chamber 13 and the water sprinkling hole 14. A rectifier network 14a is incorporated. In addition, an air intake is provided in the center of the water spray head 12. The draw tube 15 is raised in the axial direction, and the inside thereof is made into an air hole 15a to form each foaming chamber. This allows communication between the bar 13 and the outside air.

[0027] At the upper end side of the interior of the water spray head 12, water from the internal channel 11a is formed into foam-forming channels. A distribution block 16 for distribution to the chambers 13 is fixedly provided. This distribution block The upper and lower surfaces of the chamber 16 are flat, and the communication channel 16 is coaxial with the core of each foaming chamber 13. a is opened, and the air hole 15a is opened without interfering with the upper end of the air suction cylinder 15. These channels are communicated with each foaming chamber 13. And these communication routes 1 The flow passage area of 6a is much smaller than the cross section of the foaming chamber 13, and the inner The water from the partial flow path 11a is accelerated in the communication path 16a and then enters the foaming chamber 13. is released all at once. Therefore, when water is supplied, foam is generated due to the increased speed of water. As the internal pressure of the chemical chamber 13 decreases, external air is sucked through the air hole 15a. Ru. Then, the resistance by the rectifying net 14a provided at the lower end of the foaming chamber 13 is utilized. By allowing the water to stagnate a little, the sucked air can be removed from this stagnation. Mix in water. As a result, the supplied water is foamed in the foaming chamber 13. Ru.

[0028] Furthermore, inside the main body 11 separated by the distribution block 16, each communication hole 1 is provided. An intermittent water supply mechanism is provided to intermittently supply water to 6a. This intermittent water supply mechanism is It is fixed to the main body 11 coaxially with the internal flow path 11a, and the lower surface is placed above the distribution block 16. A casing block 17 placed against a surface and a rotating water wheel placed inside the casing block 17 18. Figure 11 shows the casing block 17 and the rotating water turbine 1. 8 is a cutaway perspective view showing an outline of the casing block 17, and the peripheral wall of the casing block 17 has a plurality of holes. 17a is open. Further, the rotary water wheel 18 is configured to rotate in the radial direction. It has a plurality of blades 18a tilted in the opposite direction, and connects three of these blades 18a rows. As shown, the shielding plate 18b is integrated with the bottom surface. This shielding plate 18b is the distribution plate 16 It is large enough to block the communication hole 16a of the hole and can be provided in one or several places. The bottom surface slides over the top surface of the distribution block 16 as shown in FIG. Ru.

[0029] In the above configuration, water from the internal flow path 11a flows through the casing block through the hole 17a. This causes the rotating water wheel 18 to move in the direction of the arrow in FIG. Rotate to . Therefore, as the rotary water wheel 18 rotates, the shielding plate 18b acts as a distribution block. The connection path 16a of the lock 16 is closed in order and then reopened, and the connection path 16a and the inner It communicates with the partial flow path 11a intermittently. For this reason, the water supply to each foaming chamber 13 is Water is also spouted intermittently from the water sprinkling hole 14 at its lower end, as in the previous embodiment. Intermittent water spouting using all of the water sprinkling holes 14 becomes possible. and contact as above The high-speed flow from the hole 16a draws air from the air hole 15a, which causes The water supply becomes foamy. Therefore, from the water sprinkling hole 14, foamy water is spouted intermittently. and a soft-touch massage shower.

[0030]

[Effect of the idea]

In this invention, the supplied water is turned into foam and this is intermittently discharged from the water outlet end, which is different from the conventional method. Compared to a shower that releases a mass of water all at once, the shower water spray is softer. In addition, the water splash after hitting the body is also smaller. For this reason, around the shoulders and neck Easy to use without getting your face wet even when taking a shower. Also, the flow rate Even if you make it too big, the shower contains air bubbles, so you won't feel any pain and it will be soft. It provides strong stimulation, and the flow rate can be roughly adjusted, improving usability.
