Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an attachment for spouting hot water that can be placed at any position on the wall surface of a bathtub, separate from a pump for supplying hot water.

[Conventional technology]

The hot water in the bathtub is sucked and mixed with air, or the hot water is squirted into the bath at the required pressure without mixing air, and this jet stream stimulates the bather's skin to perform in-bath pine surge. A conventional bath jet device is a type in which a nozzle and a pump are integrated and placed together immersed in the hot water of a bathtub. The mixture is mixed with hot water sent through the hose and is jetted into the bath from the nozzle with the required pressure.

[Problem that the invention attempts to solve]

However, with conventional devices, the pump is placed inside the bathtub and the pump is connected to a nozzle installed inside the bathtub with a hose, which makes the inside of the bathtub that much smaller and the hose gets in the way. I had the inconvenience of not being able to do pine massage while taking a bath because I felt so relaxed. In addition, when performing pine surge in a bath, it is performed using one jet stream ejected from one nozzle, so it is not possible to pine surge the multiple different areas at the same time with multiple jet streams. The effect was still insufficient.

In order to solve the above-mentioned inconvenience of narrowing the inside of the bathtub, the present inventor has proposed an ejection device that allows the pump to be placed outside the bathtub so that the inside of the bathtub can be used widely.

This invention was made as part of that development, and its purpose is to allow you to enjoy pine surge in a relaxing bath without cramping the inside of the bathtub, and to also provide pine surge with multiple jets. To provide an attachment for spouting hot water that can exhibit sufficient effects.

[Means for solving problems]

In order to achieve the above object, the present invention employs the following means. That is, the present invention has a body part that is separated from the hot water supply pump and is removably fixed to the wall surface of the bathtub with a suction cup. One or more hot water spray nozzles or air mixing hot water jetting nozzles are provided at least on the arm side of the tip of each arm and the body portion, so that the nozzles of both the left and right arms can simultaneously jet the hot water. The nozzle is composed of either a composite nozzle that can switch between spraying hot water and spouting air-mixed hot water, and a single-function nozzle that has only one of the functions, and at least One nozzle is constituted by a nozzle having an intermittent jetting function of hot water, thereby solving the problem.

[Effect]

The hot water spouting attachment of the present invention can be attached to an appropriate wall surface position of a bathtub or bathroom using a suction cup placed on the back side of the body. In this state, when the flow passage leading to each nozzle is communicated with the discharge port of the pump and the pump is started, hot water supplied from the pump is guided to the corresponding nozzle through the flow passage. Depending on the type of nozzle used, the bather can receive a desired jet flow from this nozzle, such as a jet jet of air-mixed hot water or a shower jet of only hot water, depending on the type of nozzle used. An intermittent shower or intermittent jet jet is emitted from the jet.

In this specification, the terms "shower" and "jet" are distinguished, with the term "shower" meaning when only hot water is spouted, and "jet" meaning spouting out a mixed fluid of hot water and air.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

1 to 3 are front views of various types of hot water spouting attachments according to the present invention.

In Figures 1 to 3, an appropriate number of suction cups are attached to the back surface of the body part 1, and the body part 1 is fixed to an appropriate position on the inner wall of the bathtub by suction using these suction cups. ing. In the attachments shown in Figures 1 and 3, there is one first attachment on the front side of the body part 1.
The nozzle 2 is provided almost in the center, and the second
In the attachment shown in the figure, this first nozzle 2 is omitted. Arms extend in multiple directions from the body portion 1 of each attachment. In the attachment shown in each figure, two arms 3a, 3
b extends laterally from both left and right sides of the body portion 1,
A second nozzle 4 is installed at the tip of each arm 3a, 3b.
a and 4b are provided.

Although the arms 3a and 3b can be made of rigid tubes, they are preferably made of flexible tubes, and the arms 3a and 3b shown in FIGS. The arms 3a and 3b shown in FIG. 3 are made of flexible hoses (rubber hoses in the figure). has been done. This arm 3
A, 3b and the body portion 1 may be connected non-removably by adhesive or the like, but in this embodiment, a pipe joint 5 with a valve is used to removably connect them in an airtight manner. In addition, the pipe fitting 5 with a valve consists of a plug with a built-in valve and a socket without a valve.
The valve is opened to open the fluid passage only when the plug and the socket are connected, and the plug is attached to the body part 1. In this way, when the arms 3a and 3b are detachably connected, it is also possible to use the arm with the unused arm removed. There is no particular problem if these arms 3a, 3b are made of flexible metal tubes, but one or both of these arms 3a, 3b may be made of a flexible hose made of rubber or the like. In this case, it is difficult to hold the second nozzles 4a, 4b attached to the tip of the flexible hose in any deformed position, so a suction cup is attached to the back side of the jet nozzle 4a, 4b, and this suction cup is used. Place the second nozzles 4a and 4b so that they face the area where you want to receive pine surge, for example, your shoulders or the nape of your neck.
a, 4b are held at desired positions on the inner wall surface of the bathtub.

A hot water suction pipe 6 extends upward from the body portion 1.
The hot water suction pipe 6 is removably connected to a water supply pipe 7 leading to the discharge port of the pump by a pipe joint 8. A flow path is formed inside the body portion 1 to communicate the hot water suction pipe 6 with the first nozzle 2 or the second nozzles 4a, 4b. A flow path switching unit 10 is provided at a branch position of each flow path leading from the hot water suction pipe 6 to the first nozzle 2 or the second jet nozzle 4a, 4b (FIGS. 4 and 5). . Although various means can be adopted as this flow path switching unit 10, in this embodiment, a manually operated switching lever 11
The flow path is switched by.

The flow path switching section 10 shown in FIG. 4 is for the attachment shown in FIGS. 1 and 3 in which a first nozzle is provided in the body 1. A connected valve 12;
It consists of a receiving part 13 that fits into this valve 12, and a central axis hole 14 of the valve 12 communicates with the flow path of the hot water suction pipe 6. Inside this valve 12, for example, branch flow passages 15b and 15c are arranged counterclockwise at 135° and 180° with respect to the branch flow passage 15a.
On the other hand, on the side of the receiving portion 13, the flow passages 16a and 16b are formed at positions of 90° and 135° counterclockwise with respect to the flow passage 16c passing through the center in the diametrical direction. It is formed. The flow passage 16a communicates with the first nozzle 2, similarly the flow passage 16b communicates with the second nozzle 4a, the flow passage 16c communicates with the second nozzle 4b, and the flow passage 16b and the flow passage 16c communicate with each other. They are in communication via the groove 19. Therefore, in the state shown in FIG. 4, hot water is supplied from the pump to each nozzle 2, 4a, 4b.
It is ejected simultaneously from both sides (Fig. 6a). For example, if the switching lever 11 is rotated 45 degrees counterclockwise from this position, the branch flow passage 15b will communicate with the flow passage 16c, and hot water will be spouted from the second nozzles 4a and 4b (Fig. 6). b). If the switching lever 11 is further rotated 45 degrees counterclockwise from this position, the branch flow passage 15a and the flow passage 16a will be communicated with each other, and hot water will be spouted only from the first nozzle 2 (Fig. 6c). ). In this embodiment, in order to facilitate the combination operation of hot water spout positions, a mark 17 is marked at the tip of the switching lever 11, and a mark 17 is marked on the body part 1 side at equiangular intervals of 45°. A scale 18a of 1, a scale 18b of 2 circles, and a scale 18c of 3 circles are provided in this order, and when the mark 17 is aligned with the scale 18a, the first nozzle 2 will move the same mark 17 to the scale 18b. When the mark 17 is aligned with the scale 18c, hot water is simultaneously ejected from the second nozzles 4a, 4b, and from the three nozzles 2, 4a, 4b when the mark 17 is aligned with the scale 18c.

On the other hand, the flow path switching section 10 shown in FIG.
This is for the attachment shown in FIG. 2, which does not have the first nozzle 2, and this flow path switching section 10 is also similar.
a valve 12 connected to the switching lever 11;
It consists of a receiving part 13 that fits into this valve 12, and a central axis hole 14 of the valve 12 communicates with the flow path of the hot water suction pipe 6. Inside the valve 12, for example, branch flow passages 15b and 15c are arranged counterclockwise at 135 degrees with respect to the branch flow passage 15a as a reference.
On the other hand, on the side of the receiving portion 13, the flow path 16 is formed with the flow path _16a1 as a reference.
a ₂ and 16b are formed at positions of 90° and 180° counterclockwise, respectively. The flow passages 16a ₁ , 16a ₂
is connected to the nozzle 4a, and similarly the flow path 16b is connected to the nozzle 4a.
communicates with the nozzle 4b. Therefore, in the state shown in Fig. 5, hot water supplied from the pump is distributed to each nozzle 4.
They are ejected simultaneously from a and 4b (Fig. 7a). For example, when the switching lever 11 is rotated 45 degrees counterclockwise from this position, the branch flow passage 15b is changed to the flow passage 1.
6b, and the branch flow passage 15a is closed, so hot water is spouted from the nozzle 4b (7th head c). From this position, the switching lever 11
If you rotate it 45 degrees counterclockwise, the branch flow passage 15
A communicates with the flow path _16a2 , and hot water is ejected only from the ejection nozzle 4a (FIG. 7b).
In this embodiment, when the mark 17 is aligned with the scale 18a, the nozzle 4a starts, when the mark 17 is aligned with the scale 18b, the nozzle 4b is started, and when the mark 17 is aligned with the scale 18c, the two nozzles 4a, 4
Hot water is supposed to gush out from b at the same time.

By the way, as for the nozzles provided in the body part 1 or the arms 3a and 3b, there are three types of nozzles that can be used: a shower nozzle, a jet nozzle, and a composite nozzle of these nozzles. Nozzles for injection and those for intermittent injection can be used selectively, and any combination of these types of nozzles can be used depending on the user's specifications (this implementation In the example at least one nozzle for intermittent injection is used).

The shower nozzle is, for example, as shown in FIG. 8a, in which a plurality of hot water spout holes 21 are provided in the front part 20, and the jet nozzle is as shown in FIG. 8b, in which a jet is provided in the center of the front part 20. A blowout hole 22 is provided. Further, as shown in FIG. 8c, the composite nozzle is provided with a jet nozzle 22 in the center of the nozzle front part 20, and a plurality of hot water spouts 21 around the jet nozzle 22. The nozzle is equipped with a switching mechanism to switch between shower jet and jet jet, and if hot water is jetted continuously, it becomes a continuous jet nozzle, and if an intermittent jetting mechanism is added and hot water is jetted intermittently, it becomes an intermittent jet nozzle. becomes.

In FIGS. 1 and 3, the first nozzle 2 is constructed of a jet jet nozzle, and the second nozzles 4a and 4b are constructed of composite nozzles in both FIGS. 1 to 3. However, the first nozzle 2
may be configured by a shower nozzle or a composite nozzle, and the second nozzles 4a and 4b may be configured by a shower nozzle or jet nozzle, and in some cases, one side of the second nozzle 4a
and the other side 4b may be different types of nozzles.

FIG. 9 shows an example of the configuration of a composite nozzle.

In FIG. 9, a first partition member 24 having an H-shaped cross section is installed in a housing 23 formed by fitting a frame 23a on the front side and a frame 23b on the back side.
and a second partition member 25 on which the same member 24 is placed are housed to form an air flow mixing chamber 26 between both partition members 24 and 25.
A fluid chamber 27 is formed between the frame body 23b on the back side and the frame body 23b on the back side. The frame body 23a on the back side is the arm 3
The fluid chamber 27 and the conduit 28 of the arms 3a, 3b are connected to the flow passage 3 provided in the frame 23b via a valve 30.
1a and 31b. Similarly,
The pipe line 28 and the air flow mixing chamber 26 are also communicated via a valve 30 and a flow passage 34 provided within the frame body 23b. A T-shaped flow passage 32 is formed inside the valve 30, and by rotating a lever 33 connected to the valve 30, the pipe line 28 is opened.
The hot water from the flow path 31b is switched to the flow path 31b side and the flow path 34 side.

Further, a space surrounded by the housing 23, the first partition member 24, and the second partition member 25 is a passage chamber 35, and this passage chamber 35 and the fluid chamber 27 are connected to the first partition wall. It communicates with the member 24 through a communication hole 36 provided in the peripheral wall thereof. A valve 37 is housed between the second partition member 25 and the front frame 23a, and is rotatable in any direction.
A jet nozzle 38 is formed through the center of the valve 37. This jet outlet 38 communicates with the air flow mixing chamber 26 through a hole 39 formed in the center of the second partition member 25.
On the other hand, a space surrounded by the front frame 23a, the second partition member 25, and the valve 37 forms a hot water inflow chamber 40. And this hot water inflow chamber 4
The tip wall of Nozzle 0, that is, the front part of the nozzle has the 11th
As shown in the figure, shower hole groups 42a, 42b, and 42c consisting of a plurality of shower holes 41 are provided surrounding the jet nozzle 38 at three equal positions on the circumference.

On the other hand, as shown in FIG.
An air conditioning shaft 43 is rotatably supported on b. An air introduction hole 44 for introducing air from the outside is formed at the tip of the air adjustment shaft 43 in a direction perpendicular to the longitudinal direction of the shaft.
communicates with the air flow mixing chamber 26 through a coaxial shaft 43 and a passage 45 provided in the frame body 23b on the back side.
A lever 46 is provided on the base end side of the air adjustment shaft 43, and by operating this lever 46 and rotating the air adjustment shaft 43, the air introduction hole 44 is opened.
The overlapping area at the junction between the opening cross-sectional area of the passageway 45 and the opening cross-sectional area of the passage 45 changes, and by changing the overlapping area in this way, air is introduced from the outside into the mixing chamber 26 due to the ejector effect. It regulates the amount of air.

In such a configuration, in the state shown in FIG.
Since the flow passage 31b leading to the fluid chamber 27 is closed by the valve 30, the hot water supplied from the pump passes through the flow passage 34 and flows into the air flow mixing chamber 26. The liquid enters the water, passes through the flow path 34 of the second partition member 25, and is vigorously ejected from the jet ejection hole 38. During this injection of hot water, external air introduced from the air introduction hole 44 is drawn into the air mixing chamber 26 by the ejector effect of the jet stream, and mixed with the hot water in the air mixing chamber 26. Then, this mixed hot water becomes a jet flow and enters the jet injection hole 3.
8 and is ejected into the bathtub.

If the lever 33 is rotated 90 degrees clockwise in the state shown in FIG. 9, the arms 3a, 3
A flow passage 31b communicating with the pipe line 28 of b and the fluid chamber 27
The flow path 34 is closed by the valve 30, so hot water supplied from the pump flows through the flow path 3.
It enters the fluid chamber 27 through 1b, and further into the passage chamber 35 through the communication hole 36. This hot water is further transferred from the passage chamber 35 to the second partition member 2.
The hot water enters the inflow chamber 40 through a passage 49 provided at 5, and is ejected from the shower hole 41 as a shower jet.

In this example, in order to enhance the pine surge effect,
The shower jet is emitted intermittently. That is, the impeller 4 is provided in the hot water inflow chamber 40.
7 is rotatably housed. This impeller 47
A plurality of blades protrude radially from the shaft at equal angular intervals of 120°, and one shower hole group 42a is provided at the end of one of the blades (the end on the jetting surface side). Alternatively, a closing plate 48 having an area necessary to cover 42b or 42c is fixed. This impeller 47 rotates under the pressure of hot water sent from the pump when it enters the hot water inflow chamber 40, and the rotation of this impeller 47 causes the closing plate to rotate. 48, each shower hole group 42a, 42b, 42c is sequentially closed every 1/3 rotation, so the hot water spouted from each shower hole group 42a, 42b, 42c becomes an intermittent shower and is spouted outside. The Rukoto.

FIG. 12 shows an example of the structure of an intermittent shower nozzle. This intermittent shower nozzle includes a valve 30 and a lever 33 that constitute the composite nozzle.
, a valve 37, and an air adjustment shaft 43 for introducing air.
and the lever 46 are omitted, and further,
The flow path 34 and hole 39 are omitted. The other configurations are the same as the composite nozzle, so the ninth
- The same members as those in the composite nozzle shown in FIG. 10 are designated by the same reference numerals.

This intermittent shower nozzle is designed to guide hot water from the pipe line 28 to the hot water inlet chamber 40 through the flow passage 31a, the fluid chamber 27, the communication hole 36, and the passage chamber 35 in order, and the pressure of the flowing hot water Then, the impeller 47 is rotated. As the impeller 47 rotates, each shower hole group 42a, 42b, 42c is closed by the closing plate 48 every 1/3 rotation, so each shower hole group 42
The hot water ejected from a, 42b, and 42c becomes an intermittent shower and is ejected to the outside.

FIGS. 13 and 15 show an example of the construction of an intermittent jet nozzle, in which the same parts as those of the composite nozzle are designated by the same reference numerals. This intermittent jet nozzle omits the lever 33 among the components of the composite nozzle shown in FIGS. For example, the jet nozzles 51a, 51b, 51c in the front part have a circumference of 3
Circular holes are formed at equal positions, the diameter of the opening end being smaller than the diameter of the inside of the hole, and the air-mixed hot water is spouted from these spout holes generally parallel to or slightly centripetally oriented. . Then, the communication hole 36 of the first partition member 24 is omitted, and a communication hole 52 is formed in the partition member 24 to communicate the air flow mixing chamber 26 and the passage chamber 35, and hot water supplied from the pipe line 28 is passed through the flow path. 31a, 32, and 34 to the airflow mixing chamber 26, and is mixed with air flowing from the air introduction hole 44 through the passage 45 by the ejector effect. Further, the closing plate 4 is attached to the end of the blade of the impeller 47 on the side of the ejection surface.
8 is the jet nozzle 51a or 51b or 5
Both are flat plates with an area sufficient to completely cover 1c.

Therefore, when a mixture of hot water and air enters the hot water inflow chamber 40 from the airflow mixing chamber 26 through the communication hole 52 and the passage 49, the impeller 47 is rotated by the inflow pressure, and the impeller 47 is 51a,
Since each jet nozzle 51b, 51c is closed every 1/3 rotation, each jet nozzle 51a, 51b, 5
From 1c, the mixed hot water becomes an intermittent jet and is spouted to the outside.

Note that if the impeller 47 is removed from the intermittent injection nozzle shown in FIG. 12 and the intermittent jet nozzle shown in FIGS. 13 to 15, each becomes a continuous injection nozzle.

As described above, in this embodiment, the arms 3a, 3b
The arms 3a and 3b are made of flexible metal tubes or flexible hoses, so as shown in Figs. Nozzle 4a, 4
b can be fixed, and is extremely convenient to use.

In addition, since the attachment is separate from the pump, it can be installed in any desired position in the bathtub or bathroom, and the pump can also be placed in any position outside the bathtub. , design flexibility is increased, and there is no need for a connecting member to connect the pump and attachment, so the area around the bathtub does not become cluttered.
The device has an extremely simple configuration, and the inside of the washing area and bathtub can be used more widely and comfortably.

Furthermore, in this embodiment, the first nozzle 2 and the second nozzle
It is possible to receive a pine surge in the bath by the jet flow from the nozzles 4a and 4b, and therefore, for example,
the back by the first nozzle 2, the second nozzle 4
With a and 4b, you can massage your desired areas, such as both shoulders, and by ejecting jets from all the nozzles, you can massage multiple jets such as the shoulders and back. It is very convenient because it not only allows you to simultaneously perform pine surge on multiple parts of the body, but also allows you to switch the jet stream between shower and jet at will. It's also big.

Note that the present invention is not limited to the above-mentioned embodiments, and can be implemented in various ways.
For example, in the above embodiment, the hot water switched by the flow path switching unit 10 passes through the corresponding flow paths to the target nozzles 2, 4a, 4b (second
The attachments in the figure lead to 4a and 4b), but
In addition to this flow path switching section 10, each nozzle 2, 4a, 4
A valve for shutting off hot water may be provided in each of the flow paths leading to the flow path 4a and 4b in the attachment shown in FIG. 2 (in this case, the flow path switching section 10 can be omitted), or a Nozzle 2,
A valve for stopping hot water may be integrally provided in 4a and 4b, and the jet flow may be interrupted by operating the valve while receiving pine surge in the bath.

Also, for the attachments in Figures 1 and 3,
Although one nozzle 2 is provided in the body portion 1, a plurality of nozzles 2 may be provided. Furthermore, in the above embodiment, a second
However, as shown in FIG. 8, a plurality of nozzles of the same type or different types may be provided at the tip of each arm 3a, 3b.

Further, in the above embodiment, a pair of arms 3a and 3b are extended from the body 1, but the number of arms is not particularly limited, and three or more arms may be provided protruding from each other. 2nd at the end of the arm
A nozzle may be provided. Furthermore, a universal joint may be provided at the connection between the arm and the second nozzle so that the direction of the nozzle can be changed arbitrarily. Similarly, a universal joint may be employed at the connection between the arm and the body portion 1 so that the arm can be rotated to any desired position.

Furthermore, although the composite nozzle of this embodiment switches between the shower jet and the jet jet, the shower jet and the jet jet may be applied simultaneously.

Furthermore, as another configuration aspect of this embodiment, for example, as shown in FIG. It may also be used as

[Effect of idea]

The present invention has an attachment equipped with multiple nozzles separated from the hot water supply pump, so the attachment can be placed anywhere in the bathtub with a suction cup, and can be placed around the bathtub. can be easily configured. In addition, since the hose does not get in the way, you can use more space inside the bathtub.In addition, you can receive the pine surge with both hands free, so you can feel relaxed while taking a bath. You can enjoy pine surge. Furthermore, since this attachment has arms that extend from the torso to at least the left and right sides, each of these nozzles can be used to massage the shoulders, neck, back, etc., and the nozzles on both the left and right arms can emit jets of water. By ejecting, you can receive multiple jets at the same time and massage multiple areas including your back and shoulders at the same time. Moreover, since at least one nozzle is configured with an intermittent jet nozzle, it is highly irritating to the skin.
Therefore, the pine surge effect is also significant.
