DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An articulated hose according to the present invention will now be described with reference to the accompanying drawings, showing an embodiment in which the hose is applied to a bathtub hot water circulation purifying apparatus.
FIG. 1 shows a multi-joint free hose 1 according to the present invention applied to a bath tub hot water circulation purification device 2 in a bath apparatus. In the articulated hose 1, a plurality of hose units 1a, 1b, and 1c are sequentially connected via a ball joint portion 3 provided on one end side and having a swelling shape in a spherical shape, and can be freely swung within a predetermined angle range. It has a simple structure. That is, the articulated hose 1 returns the purified hot water from the main body 5 mounted on the base 4 for fixing to the bathtub of the bathtub hot water circulation / purification device 2 so as to return the hot water into the bathtub.
And a nozzle portion 6 is rotatably provided at the end so that hot water can be ejected within a predetermined range.

As will be described later, the bathtub hot water circulating / purifying device 2 itself is fixedly installed at a corner of the bathtub, and the main body 5 of the bathtub hot water circulating / purifying device 2 is installed in the bathtub via the base 4. In this case, the main body 5 has a filtering section 7 provided so as to be buried in warm water in the bathtub. The bathtub water taken in through the filtering section 7 is subjected to purification treatment such as deodorization and sterilization. Then, hot water is ejected from the nozzle section 6 through the articulated hose 1. Note that the structure of the main body 5 in the bathtub hot water circulation / purification device 2 has a well-known configuration, and a detailed description thereof will be omitted here.

Next, the articulated free hose 1 will be described in detail focusing on the ball joint 3.
That is, the articulated free hose 1 can be constituted by, for example, a rubber hose. As shown in FIG. 2, the ball joint portion 3 has a spherically expanded outer shell 8,
The movable part 9 and the hose unit 1 are provided on the spherical inner wall surface of the outer shell 8.
A (or hose unit 1b) is connected with a short tubular hard resin connecting member 10 for connection, and a detachment prevention ring 11 is placed over the outer shell 8. The outer shell 8 of the ball joint 3 is a hose unit 1a.
(Or the hose unit 1b), and the movable part 9 can be forcibly fitted, and can have a watertight structure. Further, the position of the short tubular connecting member 10 for connecting the inner spherical movable portion 9 of the ball joint portion 3 and the hose unit 1a (or the hose unit 1b) is set at 90 degrees minus the center line of the hose. The head can be turned 90 degrees at the time of maximum swing.

Next, the nozzle section 6 at the tip of the articulated free hose 1 will be described with reference to FIG. That is, the nozzle 6 is swingably connected to the ball joint 3 at the tip of the hose unit 1a. In this case, the nozzle 6
It is configured to be integrally connected to a short tubular connecting member 12 integrally formed with the movable portion 9 having the inner spherical surface of the ball joint 3. Further, the nozzle portion 6 has a shape in which the passage of the nozzle base portion 13 connected to the connecting member 12 is conically narrowed in a conical cross section toward the nozzle tip portion 14 for ejecting hot water. In addition, an air introduction pipe 15 for guiding outside air is connected to the joint between the nozzle base 13 and the nozzle tip 14 by minimizing the inner diameter of the passage,
The structure is such that the air is sucked into the hot water by the flow pressure of the hot water passing through the joint, and is sent into the bathtub as a fountain flow containing bubbles.

The bathtub hot water circulation / purification device 2 to which the above-described articulated hose 1 is applied is installed at one corner of the upper edge 21 of the bathtub 20 via the base 4 as described above. However, the articulated hose 1 is detachably held on the inner wall surface of the bathtub 20 via a hose fixing part 22 (see FIG. 4). The hose fixing part 2
2 has a receiving frame 24 that resiliently holds the hose unit 1a in a holding frame 23 held on the inner wall surface of the bathtub 20.

In the articulated hose 1 constructed as described above, the articulated hose 1 is usually resiliently held on the inner wall surface of the bathtub 20 by the receiving frame 24 of the hose fixing part 22. Can be done, for example, without getting in the way when taking a bath. And at the time of use, bather
When the hose unit 1a of the articulated hose 1 is pulled away against the holding force of the receiving frame 24 of the hose fixing part 22, the ball unit 3 freely connects the hose unit 1b and the hose unit 1c. It can be swung horizontally, and further, can be swung vertically, horizontally and obliquely within a predetermined range by the ball joint 3 connecting the hose units 1a to 1c and the nozzle 6. Nozzle tip 14
Can be directed in a desired direction to generate a jet flow containing bubbles, and the function of the bathtub hot water circulation / purification device 2 can be maximized.

[0011]

According to the present invention, since the discharge nozzle can be used close to a desired position, it can be said to be optimal for a bathtub hot water circulation purifying apparatus in a 24-hour bath.
