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.

The present invention was developed 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 provide pine surge with multiple jets. To provide an attachment for spouting hot water that can sufficiently exhibit its effect.

[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 of the bathtub with a suction cup, and arms extending from this body part at least on both left and right sides. The tip of each arm and the body are each provided with one or more hot water sprinkling nozzles or air-mixing hot water spouting nozzles, and the insides of the arms and body are provided with hot water or air flowing through the corresponding nozzles. A flow path is formed to enable simultaneous ejection of two or more nozzles, and
The nozzle is composed of either a composite nozzle that can switch between spouting hot water and 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 also a means to solve problems.

[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. From this nozzle, the bather can receive a desired jet stream depending on the type of nozzle used, such as a jet jet of air-mixed hot water or a shower jet of only hot water.

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.

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. One or more first nozzles are provided on the front side of the body portion 1, and in FIG. 1, one first nozzle 2 is provided approximately at the center.

Although the arms 3a and 3b can be made of rigid tubes, they are preferably made of flexible tubes, such as flexible hoses that can maintain a fixed shape in any deformed state. It can be constructed from a flexible metal tube known as a metal tube or a flexible rubber hose. In this embodiment, both arms 3a and 3b are made of flexible metal tubes. The arms 3a, 3b and the body portion 1 may be irremovably connected 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. The pipe joint 5 with a valve consists 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 to 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.

As mentioned above, in FIG. 1, both arms 3a, 3b
Both arms 3a and 3b are made of flexible tubes made of metal, but if one or both of these arms 3a and 3b is made of a flexible hose such as rubber, there is a Since it is difficult to hold the attached second nozzles 4a, 4b in any deformed position, a suction cup is attached to the back side of the jet nozzle 4a, 4b, and this suction cup is used to deform the second nozzle 4a, 4b. Point the nozzle 4 toward the area you want to receive pine surge, for example, your shoulders or neck.
a and 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. 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 that 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 jet nozzles 4a, 4b.
(Figure 2). This flow path switching section 1

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 receiving part 13 side, the flow passages 16a and 16b are formed counterclockwise with respect to the flow passage 16c that passes through the center in the diametrical direction. 90° in the direction and
It is formed at a position of 135°. The flow path 16a
communicates with the first nozzle 2, and similarly the flow path 1
6b is connected to the second nozzle 4a, and the flow path 16c is connected to the second nozzle 4a.
The flow passages 16 are connected to the nozzles 4b, respectively.
b 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. 3). 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. 3c). ). In this embodiment, the switching lever 11 is
A mark 17 is marked at the tip of the body part 1, and a scale 18a with one round mark is marked at equiangular intervals of 45° on the body part 1 side.
A scale 18b with two round marks and a scale 18c with three round marks are provided in this order, and when the mark 17 is aligned with the scale 18a, the same mark 17 is moved from the first nozzle 2 to the scale 1.
8b, the second nozzles 4a, 4b
Therefore, when the mark 17 is aligned with the scale 18c, hot water is spouted from the three nozzles 2, 4a, and 4b at the same time.

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. Furthermore, as shown in FIG. 4c, 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, and inside the composite nozzle. A switching mechanism is provided for switching 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 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.

It regulates the amount of air.

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 arm 3 is rotated by 90 degrees, the arm 3
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
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.

As described above, in this embodiment, the arms 3a, 3b
The arms 3a, 3 are constructed of flexible metal tubes, as shown in FIG.
