Description

[Detailed explanation of the idea] 【Technical field】

The present invention relates to a mechanism for swinging the spray nozzle of a shower used in a bathroom or the like.

[Background technology]

Conventionally, in Japan, shower devices have been considered to be a means to cleanse the skin and can be used simply in place of bathing. However, recently it has become easier to prepare for bathing, save water,
Recognizing its advantages such as energy saving, it has come to be used as a full-fledged bathing method mainly by small families and single people, and its use is gradually increasing. On the other hand, as social needs for health promotion increase, attention is being paid to the skin irritation and thermal effects caused by the spray pressure of showers. In other words, a stimulating hot bath can increase blood volume and activate various functions that are closely related to health and beauty, such as the circulatory system, respiratory system, and autonomic nervous system, thereby relaxing the mind and body. It has been sought after to be effective in recovering from fatigue and improving beauty. In order to make these effects even greater, it is necessary to vary the temperature and water pressure of the jet water so that the stimulating effect of the jet water lasts as long as possible, and to make sure that as much hot water is applied to the whole body as possible. It will be necessary to devise measures such as spraying. By the way, regarding conventional shower devices, from the perspective of changing the injection position of the nozzle, there is a replacement type shower head in which the shower head can be removably hooked to fixed hanger hooks provided in two stages, upper and lower. (not shown) and the 16th
As shown on the left side of the figure, the spray angle of the nozzle part of the fixed shower head 7 can be adjusted manually, or as shown on the right side of Fig. 16, the spray head 7 can be adjusted manually using a slide bar 8. Generally, the height can be adjusted freely. These characteristics are
Compared to a shower head that is operated by holding it in your hand, you can move your body toward the jet of water that is ejected from a fixed shower head, giving you more freedom. Although it can be adjusted, the shower head has a fixed position during use, which limits the spray area.
In addition, attempts have been made to install multiple shower heads and make the spray angles of each shower head slightly different in order to widen the spray area. Since the angle is constant and the spray is sprayed at the same location on the body, there is no change in skin stimulation, the stimulation pressure is paralyzed and the stimulation sensation quickly fades, and there is no long-lasting stimulation. In addition, it is necessary to fine-tune the spray angles of a plurality of nozzles individually, which is time-consuming and troublesome, and there are problems in that a large amount of hot water is used and running costs are high.

[Purpose of invention]

This invention was developed in view of the technical background described above, and its purpose is to expand the spray area of the shower using a compact shower head and a small amount of hot water, and to increase the duration of stimulation. The purpose is to activate the shower effect.

[Disclosure of invention]

The oscillating shower head device of the present invention has an injection nozzle section 2 rotatably attached to a stationary main body 1, a water wheel 3 rotated by water flow, and arranged on the same axis between the water wheel 3 and the injection nozzle section 2. The water turbine 3, the reduction gear train 4, and the injection This device is characterized in that the connecting portion of the nozzle portion 2 with the reduction gear train 4 and the reversing mechanism 5 are housed within the stationary main body. By oscillating the spray nozzle part 2 using water pressure, water is sprayed from the fixed shower head over a wide area of the body, and since the spray position changes, the stimulation does not fade and continues to be stimulated. It provides a high shower effect. Moreover, since the water pressure rotates the water turbine 3, the reduction gear train 4 reduces the rotation speed, and at the same time increases the torque and transmits it to the injection nozzle section 2 to rotate the injection nozzle section 2, the mechanism can be made compact. The shower head on the stand can spray hot water over a wide area and does not consume a large amount of hot water. Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The shower head 7, as shown in FIG.
A short cylindrical injection nozzle part 2 with a partially cut out part is rotatably attached to a cylindrical fixed main body 1, and a hose joint part 10 is protruded from the outer surface of the fixed main body 1. , injection nozzle part 2
A nozzle 12 protrudes from the cutout surface, and the nozzle opening 11
At the tip is a substantially elliptical nozzle opening 1 such that the direction perpendicular to the rotational direction of the injection nozzle portion 2 is the major diameter direction.
1 is open. Note that the nozzle 12 can be replaced with one of other shapes or structures, such as a conical one, a foam type one, or a pulse pulsating type one. In this case, the connection part of the nozzle 12 can be replaced with a The nozzle 12 can also be replaced easily by using an in-point type. As shown in FIGS. 2, 4, and 6, a nozzle connection chamber 13 is provided at the front of the stationary body 1, a water turbine chamber 14 is provided at the rear, and a hose connection chamber 14 is provided at the rear. Inflow chamber 15 on the inlet part 10 side
is provided, and a reduction gear chamber 16 is provided on the opposite side. The injection nozzle part 2 has a shaft part 17 protruding from the rear end inserted into the nozzle connection chamber 13 of the stationary main body 1 and rotatably supported by the chamber wall of the nozzle connection chamber 13. A drive gear 18 is formed at the tip, and a water channel 19 formed in the shaft portion 17 opens on the circumferential surface of the shaft portion 17 within the nozzle connection chamber 13 . In the water wheel chamber 14, as shown in FIG. Reduction gear train 4 consisting of gears
is built in, and the starting end of the reduction gear train 4 is connected to the water wheel 3.
The terminal end of the reduction gear train 4 is connected to the drive gear 18 of the injection nozzle section 2, so that the rotation of the water turbine 3 is transmitted to the drive gear 18 at a reduced speed. Note that the rotational speed of the injection nozzle section 2 can be adjusted by changing the gear ratio of the reduction gear train 4. On the wall between the inflow chamber 15 and the water turbine chamber 14,
As shown in FIG. 4, two injection holes 21a, 2 are inclined in different directions with respect to the rotational direction of the water turbine chamber 14.
1b is open, and as shown in FIGS. 2 and 6, a pipe 22 is passed through the reduction gear chamber 16 to directly connect the inside of the water turbine chamber 14 and the inside of the nozzle connection chamber 13. . Thus, the hot water supplied from the hose joint part 10 into the inflow chamber 15 flows into the water turbine chamber 14 from the injection hole 21a or 21b and rotates the water turbine chamber 14, and the hot water in the water turbine chamber 14 flows through the pipe 22. and flows to the nozzle connection chamber 13,
From here, it passes through the water channel 19 in the injection nozzle section 2 and is injected in a form that spreads in the direction of the rotation axis of the injection nozzle section 2, as shown in FIG. A reversing mechanism 5 as shown in FIGS. 2 and 4 is built in the inflow chamber 15. As shown in FIGS. That is, the reversing mechanism 5 has a compression spring 26 interposed between a valve 24 that swings left and right about a fulcrum 23 and an inverter 25.
One of the injection holes 21a or 21b is always closed by the elastic force of The shaft 27 of the inverter 25 projects from a through hole 28 in the chamber wall and is connected to a long hole in a cam 29 that is fixed integrally with the shaft 17 of the injection nozzle section 2. 30.
Therefore, the hot water supplied into the inflow chamber 15 is
As shown in Figure 2, the injection hole 2 on the open side
The water is discharged from 1a or 21b and collides with the blades 20 of the water wheel 3, causing the water wheel 3 to rotate in a fixed direction depending on the direction of inclination of the injection holes 21a, 21b. The rotation of the water wheel 3 is controlled by the drive gear 1 through the reduction gear train 4 as described above.
8, the injection nozzle part 2 rotates relatively slowly as shown in Fig.
Water is spouted from 1. Moreover, as the injection nozzle section 2 rotates, the cam 29 also rotates, and when the injection nozzle section 2 reaches the end of its rotation range, the inverter 25
The shaft rod 27 is pushed against the end of the elongated hole 30 and reversed, and at the same time, the valve 24 is also reversed by the action of the compression spring 26, so that the injection holes 21a, 2
1b is switched to open or close, the direction of hot water spouted from the injection hole 21a or 21b is reversed, the rotational direction of the water wheel 3 is reversed, and the injection nozzle portion 2 is rotated in the original direction. By repeating such an operation, the injection nozzle section 2 performs a swinging motion within a certain angular range due to the water pressure. thus,
As shown in Fig. 1, the jet water traces a belt-like trajectory whose width is the long axis direction of the nozzle orifice 11, and the spray area can be effectively obtained with a small spray angle to the target object. It also prevents the loss of water from splashing into excess areas, resulting in a water-saving effect. Note that in order to change the design of the swing angle, the length of the elongated hole 30 of the cam 29 may be adjusted. Shower head 7 having the structure as described above
When it is attached to the bathroom wall 31 in a horizontal position as shown in FIGS. 1 and 7, the injection nozzle part 2 will spout hot water from the nozzle 12 while shaking its head up and down, as shown in FIG. 8. When attached to the bathroom wall 31 in a vertical position as shown, the injection nozzle part 2 will eject hot water from the nozzle 12 while shaking its head from side to side. In addition, mechanisms such as the water wheel 3, reduction gear train 4, and reversing mechanism 5 are built into the stationary main body 1, and the injection nozzle part 2 is made up of a shaft part 17 and a nozzle 12, so it is lightweight, and the water pressure The required torque is reduced, and the showerhead can be driven even at low water pressure for home use.The reduction in torque allows the reduction gear and the like to be made more compact, making it possible to make the shower head 7 more compact and improving its design. Although not shown, instead of using the reversing mechanism 5 having the above-described structure, a solenoid valve or an electric valve may be used as the reversing mechanism 5 to alternately open and close the two types of injection holes 21a and 21b having different inclination directions. These solenoid valves or motor-operated valves may be remotely controlled, and the opening and closing may be switched at fixed intervals using a timer or the like. What is shown in FIG. 9 is yet another example of the present invention,
The injection nozzle part 2 is rotatably arranged between a pair of fixed-side bodies 1 and 1a, so that the injection nozzle part 2 has a dual-support structure, and a water turbine 3, a reduction gear train 4, and a reversing mechanism are installed in one fixed-side main body 1. 5, etc., and the other stationary side main body 1a has only a bearing structure.
In this embodiment, the appearance of the injection nozzle part 2 can be made left-right symmetrical, which is aesthetically superior, and the eccentricity of the rotation axis of the injection nozzle part 2 is There is no wobbling, and smooth rotation of the injection nozzle section 2 can be ensured over a long period of time. What is shown in FIGS. 10 to 14 is still another example of the present invention, and the structure of the water turbine 3, reduction gear train 4, injection nozzle part 2, etc. is the same as in the first example.
The difference is that a link mechanism 6 is used as the reversing mechanism 5. That is, the inflow chamber 15 and the water turbine chamber 14
Only one injection hole 21a inclined in one direction is opened in the wall between the water turbine 3 and the water turbine 3.
(and the reduction gear train 4) can be rotated only in a fixed direction by hot water discharged from the injection hole 21a. The reversing mechanism 5 is not directly connected to the final gear 33 of the reduction gear train 4 and the driving disk 18a of the injection nozzle section 2, but is connected via a link 32 to the reversing mechanism 5. Here the first
As shown in FIG. 4, the rotation radius R ₁ of the pivot end of the link 32 on the final gear 33 side is smaller than the rotation radius R ₂ of the pivot end of the link 32 on the driving disk 18a side, so the rotation of the water turbine 3 is When the final gear 33 rotates in one direction, the drive disk 18a rotates within a certain range, causing the injection nozzle section 2 to swing. Incidentally, the rotation angle of the injection nozzle section 2 can be adjusted by adjusting the length of the link 22. What is shown in FIG. 15 is a further embodiment of the present invention, and the water turbine 3 is similar to the embodiment shown in FIGS. 10 to 14.
The reduction gear train 4 is configured to rotate only in a fixed direction, and an eccentric, approximately elliptical cam body 33a as shown in FIG. 15 is provided at the end of the reduction gear train 4. A drive disk 18a is provided at the end, and the drive disk 18a is biased in a constant rotational direction by a tension spring 34, and the circumferential surface of the cam body 34 is brought into contact with a pin 35 protruding from the drive disk 18a. The drive disk 18a rotates due to the rotation of 34,
The injection nozzle part 2 is made to be able to swing.

[Effect of the idea]

As mentioned above, the present invention has an injection nozzle section rotatably attached to a stationary main body, a water wheel rotated by a water flow, and a water wheel and an injection nozzle section arranged on the same axis and directly connected to each other. A reduction gear train that transmits the rotation of the water turbine to the injection nozzle part, and a reversing mechanism that reverses the rotation direction of the injection nozzle part, and a connection part between the water turbine, the reduction gear train, the reduction gear train of the injection nozzle part, and the reversing mechanism. Since the body is housed in the fixed body, water is sprayed out from the fixed shower head over a wide area of the body by oscillating the spray nozzle section using water pressure, which reduces the number of shower heads installed. Moreover, since the ejection position changes, the stimulation does not fade and the stimulation lasts for a long time.The stimulation effect on the skin can be maintained, and the activation of the body including the autonomic nervous system is activated. As a result, a high shower effect can be obtained in a short time, and hot water can be sprayed over a wide area with one shower head, so there is an advantage that a high shower effect can be obtained with energy saving without consuming a large amount of hot water. In addition, since the spray nozzle section is automatically reversed, it is easy to use and allows both hands to be freely used for bathing. Furthermore, the water turbine, reduction gear train, and injection nozzle are arranged on the same axis, and the rotational force of the water turbine is directly transmitted to the injection nozzle, so there is less power attenuation and the number of parts is reduced, making it more compact. Moreover, since the water turbine, reduction gear train, connection part for the reduction gear train of the injection nozzle part, and reversing mechanism are housed in the stationary main body, it is possible to connect the reduction gear train and the reduction gear train of the injection nozzle part The water acts as a lubricant in the parts, reducing wear and the like, which also has the advantage of improving reliability.
