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]

Hot water in the bathtub is sucked and mixed with air, or hot water is jetted into the bath at the required pressure without mixing air, and this jet stream stimulates the skin of the bather to perform in-bath pine surge. Conventional bath jet devices have a nozzle and a pump that are integrated and are placed immersed in the hot water of a bathtub. The hot water is mixed with hot water sent from the hot water via another hose, and the mixture 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 and the nozzle installed inside the bathtub are connected 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 the bath, it is performed using one jet stream ejected from one nozzle, so it is not possible to pine surge the multiple different parts at the same time with multiple jet streams, and pine surge 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 developed as part of that development, and its purpose is to allow you to enjoy a relaxing bath without cramping the inside of the bathtub, and to allow the nozzle to be placed on the nape of your neck, shoulders, etc. To provide an attachment for spouting hot water which is extremely usable and can be freely repositioned in a desired direction depending on the place to be pine surged, and can fully exhibit the pine surge effect with a plurality of jets. There is a particular thing.

[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 detachably fixed to the wall surface of the bathtub with a suction cup, and from this body part there is a flow path for hot water formed in the body part. An arm connected with a flexible hose extends at least on both the left and right sides, and the end of this hose is provided with one or more hot water sprinkling nozzles or air-mixing hot water spouting nozzles. The nozzles of the arm can eject at the same time, and each nozzle is provided with a suction cup that suctions and fixes the nozzle to the inner circumferential wall of the bathtub.
The problem is that the nozzle is composed of a composite nozzle that can switch between sprinkling hot water and spouting air-mixed hot water or spouting hot water at the same time, and a single-function nozzle that has only one of the functions. It is used as a means to solve the problem.

[Effect]

The hot water spouting attachment of the present invention is attached to an appropriate wall surface position of a bathtub or bathroom using a suction cup placed on the back side of the body. Next, the nozzle at the tip of the hose is bent and moved to the most suitable position for pine surge, and then fixed to the inner wall of the bathtub using a suction cup. 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. This nozzle then uses a jet jet of your choice, 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, to perform pine surges on areas where you want to receive pine surges, such as the nape of your neck and shoulders.

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, an example of the present invention will be described based on the drawings.

FIG. 1 shows a front view of the hot water spouting attachment according to the present invention.

In FIG. 1, a suitable number of suction cups are attached to the back surface of the body part 1, and the body part 1 is fixed to a suitable position on the inner wall surface of the bathtub by suction using these suction cups. On the front side of the body part 1, a first nozzle 2 is provided approximately at the center. Also,
A hose serving as an arm extends from the body portion 1 in multiple directions. In FIG. 1, two hoses 3a, 3b extend from both left and right sides of the body 1, and second nozzles 4a, 4b are provided at the tips of each hose 3a, 3b. A suction cup 9 is provided on the back of each nozzle 4a, 4b.
Using this suction cup 9, the nozzles 4a and 4b can be attached to the inner wall surface of the bathtub or an appropriate mounting plate 29 (Fig. 3b,
(Fig. 0) is fixed by suction.

The hoses 3a and 3b are flexible hoses made of rubber or the like. Although the hoses 3a, 3b and the body portion 1 may be connected in a non-removable manner, in this embodiment, a pipe joint 5 with a valve is used to connect the hoses 3a, 3b and the body portion 1 in a removable and airtight manner. The pipe fitting 5 with a valve is composed of a plug with a built-in valve and a socket without a valve, and only when the plug and the socket are connected, the valve opens to open the fluid passage.
Attach the plug to body part 1. In this way, when the hoses 3a and 3b are connected detachably, it is also possible to use the hoses with unused arms removed.

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. Inside the body part 1, there is a hot water suction pipe 6, a first nozzle 2, and a second nozzle.
A flow path is formed which communicates each flow path with the nozzles 4a and 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 and the second nozzles 4a, 4b (FIG. 2). Although various means can be adopted as the flow path switching unit 10, in this embodiment, as shown in FIG. 1, the flow path is switched using a manually operated switching lever 11. There is.

The flow path switching section 10 shown in FIG. 2 consists of a valve 12 connected to the switching lever 11 and a receiving section 13 that fits into the valve 12. It communicates with the flow path of the pipe 6. Inside this valve 12, for example, with the branch flow passage 15a as a reference, the same flow passage 15b,
15c are formed at positions of 135° and 180° counterclockwise, and on the other hand, on the side of the receiving portion 13, the flow passages 16a and 16b are formed at opposite angles with respect to the flow passage 16c passing through the center in the diametrical direction. Formed at 90° and 135° clockwise. The flow path 16
a communicates with the first nozzle 2, similarly, the flow path 16b communicates with the second nozzle 4a, the flow path 16c communicates with the second nozzle 4b, and the flow path 1
6b and 16c are in communication via the groove 19. Therefore, in the state shown in FIG. 2, the hot water supplied from the pump is simultaneously ejected from each nozzle 2, 4a, and 4b (FIG. 3a). 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. 3b). If the switching lever 11 is further rotated 45 degrees counterclockwise from this position,
The branch flow passage 15a and the flow passage 16a communicate with each other, and the first
Hot water will be ejected only from the ejection nozzle 2 (Fig. 3c). In this embodiment, in order to facilitate the combination operation of the hot water spout positions, a mark 17 is marked at the tip of the switching lever 11, and circles are marked at equal 45° intervals on the body part 1 side. A scale 18a with two circles, a scale 18b with two circles, and a scale 18c with three circles are provided in this order.
When aligned with a, the same mark 17 will appear from the first nozzle 2.
When the is aligned with the scale 18b, the second nozzle 4
When the mark 17 is aligned with the scale 18c from the nozzles 2, 4a and 4b, hot water will be ejected simultaneously from the three nozzles 2, 4a and 4b.

By the way, in this embodiment, three types of nozzles are used: a shower nozzle, a jet nozzle, and a composite nozzle of these nozzles.
Any of these types of nozzles may be used in any combination depending on the specifications of the user.

The shower nozzle is, for example, as shown in FIG. 4a, and has a plurality of hot water spouting holes 21 in the front part 20, and the jet nozzle is as shown in FIG. A blowout hole 22 is provided. Further, as shown in FIG. 4c, the composite nozzle is provided with a jet nozzle 22 in the center of the front part 20, and a plurality of hot water jets 21 around the jet nozzle 22, inside the composite nozzle. A switching mechanism is provided to switch between the shower jet and the jet jet.

In FIG. 1, the first nozzle 2 is constructed of a jet jet nozzle, and the second nozzles 4a and 4b are constructed of composite nozzles, but the first nozzle 2 is constructed of a shower nozzle or a composite nozzle. Alternatively, the second nozzles 4a and 4b may be configured with a shower nozzle or a jet nozzle, and in some cases, one side 4 of the second nozzle
a and the other side 4b may be different types of nozzles.

FIG. 5 shows an example of the configuration of a composite nozzle.

In FIG. 5, 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 23a on the back side is the hose 3
The fluid chamber 27 and the pipe line 28 of the hose 3a, 3b are connected to the flow passage 3 provided in the frame body 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
As shown in FIG. 7, shower hole groups 42a, 42b, and 42c, which are made up of a plurality of shower holes 41, are arranged on the tip wall of No. 0, that is, on the front surface of the nozzle, at three equal positions surrounding the jet nozzle 38. It is set in.

On the other hand, as shown in FIG.
An air conditioning shaft 43 is rotatably supported on the. 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 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,
By operating this lever 46 and rotating the air adjustment shaft 43, the overlapping area at the junction between the opening cross-sectional area of the air introduction hole 44 and the opening cross-sectional area of the passage 45 changes. By changing the area, the amount of air introduced from the outside into the airflow mixing chamber 26 by the ejector effect is adjusted.

In such a configuration, in the state shown in FIG.
Since the flow path 31b leading to the fluid chamber 27 is closed by the valve 30, hot water supplied from the pump passes through the flow path 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 nozzle 3.
8 and is ejected into the bathtub.

In the state shown in Fig. 5, turn the lever 33 clockwise.
If the hose is rotated 90 degrees, the hose 3 will pass through the flow path 32a.
The pipes 28 of a and 3b communicate with the fluid chamber 27 through the flow path 31b, and the flow path 34 is closed by the valve 30, so hot water supplied from the pump passes through the flow path 31b and enters the fluid chamber 27. It then enters the passage chamber 35 through the communication hole 36. The hot water further passes from the passage chamber 35 to the hot water inflow chamber 4 through a passage 49 provided in the second partition member 25.
0 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
has a plurality of blades projecting radially from its shaft at equal angular intervals of 120°, and one shower hole group 42a or A closing plate 48 having the necessary area 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 hot water ejected from each shower hole group 42a, 42b, 42c becomes an intermittent shower and is ejected to the outside. The Rukoto.

In this embodiment, as described above, the hoses 3a, 3b
Since the hoses 3a and 3b are made of a flexible material, as shown in FIG.
b can be moved freely and then fixed to the mounting plate 29 etc. using the suction cup 9, and the spout surface can be directed to the desired area such as the nape of the neck, shoulders, chest, back, etc. for pine surge. , 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.
