[Detailed description of the invention] [Field of industrial application] The present invention relates to an in-bath jet device that sprays hot water using pump pressure. Make it moist, and
This invention relates to a bath jet device in which a pump jacket can be used in place of a headrest.

[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. Conventional bath jet devices are of the type in which the jet nozzle and the pump are both immersed in the hot water of the bathtub. The mixture is mixed with hot water sent through a hose and is jetted into the bath from the spouting nozzle at the required pressure.

[Problem that the invention attempts to solve]

However, in conventional devices, the pump is placed inside the bathtub, and the pump and the jet nozzle installed inside the bathtub are connected with a hose.
The inside of the bathtub became narrower, and the hose got in the way, making it inconvenient that I couldn't enjoy relaxing massages while taking a bath.

Of course, it is possible to take the pump out of the bathtub and place it in the washing area, but that would make the washing area smaller and the pipes for sucking and discharging hot water would occupy part of the washing area, making it difficult to wash the body. A problem arises in that it gets in the way.

This invention was made in view of the above circumstances,
The purpose is to allow wide use of the bathtub (or bathroom washing area) without constricting it, and,
To provide an in-bath jet device which allows you to massage your neck and shoulders, which tend to get stiff, in a relaxed mood without a hose getting in the way.

[Means for solving problems]

In order to achieve the above object, the present invention employs the following means. That is, the present invention provides an in-bath jet device in which hot water in a bathtub is sucked by a pump and mixed with air, or hot water is spouted into a bath at a required pump pressure without mixing air. The pump has a headrest-shaped outer jacket that can be installed on the upper edge of the bathtub, and the pump has an arm that extends into the bathtub, and the arm has one or more pumps that spray hot water into the bathtub. A means for solving the problem is that a spout is provided, and this spout communicates with the discharge port of the pump via a hot water pipe provided in the arm.

[Effect]

In the present invention configured as described above, when the pump is started, the hot water in the bathtub is sucked into the pump chamber, and the sucked hot water is sent to the back and sides of the bather from the spout of the arm extending on the inner wall of the bathtub. It can be used to squirt water into the bath to massage a wide range of areas such as the neck, shoulders, and even the chest area.
Since the outer cover of the pump is formed in the shape of a headrest, if it is used as a pillow during massage while taking a bath, you can enjoy the massage in a relaxed manner.

Provide an appropriate number.

Next, the operation of the above embodiment will be explained.

As shown in Figure 3, when you turn on pump 2 when performing bath massage during bathing,
The pump starts and the hot water in the bathtub 1 flows into the arm 6.
This sucked hot water enters the chamber of the pump 2 through the pipe in the arm 6, and the hot water at the required pressure is passed from the discharge port of the pump 2 through the flow path switching part 12. The water is guided to selected spout ports 11a to 11g, from which it is powerfully jetted into the bath. When this jet stream is received while taking a bath, appropriate stimulation is given to the skin, and jet massage is performed over the whole body, including the neck, shoulders, chest area, and even the back and hips.

By resting your head on the pillow 4 of the pump 2 during the bathing pine surge, you can enjoy the bathing pine surge in a very relaxing manner. can be used as a pillow 4.

Note that the present invention is not limited to the above-mentioned embodiments, and may take other forms. For example, in this embodiment, the jet ports 11a to 11g are connected to the corresponding water supply channels 16a to 16a through independent pipes in the arms, respectively.
For example, the water outlet 11b and the water outlet 11c communicate with the water supply channel 16b via a common pipe (in this case, the water supply channel 16c is omitted).
Various modifications of the piping route can be adopted, such as configuring it as follows. Moreover, the dividing angles of the water supply channels 16a to 16g and the branch channels 18a to 18h can also be arbitrarily determined during design.

Further, in FIG. 1, arm portions 8a, 8 of arm 6
b is extended only to approximately half of the length of the bathtub 1, but it may be extended all the way around the bathtub 1, and another arm branched from the arms 8a and 8b may be extended to the bathtub 1. It is also possible to extend the bathtub 1 along the bottom surface of the bathtub 1 and provide a spout in the extended portion so that hot water can also be spouted from the bottom surface of the bathtub 1.

Furthermore, in this embodiment, air (bubbles) is mixed with the hot water sucked from the bathtub 1, and the spout ports 11a-1
Although 1 g is squirted into the bath, only hot water may be squirted into the bath. However, if air is not mixed, no ultrasonic waves are generated in the bath, and the pine surge effect is somewhat reduced.

[Effects of the invention] In the present invention, the pump is provided with an arm equipped with a hot water spout that extends into the bathtub, and the pump is installed on the upper edge of the bathtub. This solves the conventional problem that the inside of the bathtub becomes narrow due to the large size of the bathtub.

In addition, since the hot water pipe that communicates the pump and the spout is provided inside the arm, there is no need for the hose that connects the pump and the spout to be routed around in the washing area or bathtub and get in the way. You can use the washing area and bathtub spaciously.

Furthermore, since the outer cover of the pump is in the shape of a headrest, you can rest your head on the headrest and enjoy a relaxing massage while taking a bath, and even when the pump is not activated, it can be used as a pillow. be able to.

Furthermore, since the hot water spout is provided in the arm, by setting the extension form of the arm and the installation position of the spout as desired, it can be applied to areas that tend to get stiff, such as the neck, shoulders, chest, back, and lower back. The area can be effectively massaged in the bath.
