Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for a tube for a local cleaning nozzle unit, and more particularly to a mounting structure for preventing the tube from breaking and the water in the tube from accumulating.

[0002]

2. Description of the Related Art Recently, a local cleaning device for cleaning local areas such as the hips of a human body has been widely used in flush toilets and the like by cleaning water ejected from a discharge port of a local cleaning nozzle. As shown in FIG. 5, in the conventional local cleaning apparatus, the supplied water is branched by the branch fitting 51, is supplied to the bubble unit 53 through the connection hose 52, is pressure-regulated by the pressure regulating valve, and is the heat exchanger unit 54. Sent to. Furthermore, the water that has entered the heat exchanger unit 54 is heated to a set temperature by a hot water heater, passes through a vacuum breaker, and the flow path adjustment unit 5
Sent to 6. The hot water that has entered the flow rate passage adjustment unit 56 is divided into two water passages after the water pressure is adjusted. The hot water supplied to one of the water passages is sent to the pulsation device unit 57, pressurized by the pulsation generating means, sent to the base 59 of the local cleaning nozzle unit 58, and jetted from the discharge port of the local cleaning nozzle. The hot water supplied to the other water passage is provided on a support 59a that slidably holds the local cleaning nozzle unit 58 and cleans the discharge port of the local cleaning nozzle while the tip of the local cleaning nozzle moves back and forth. It is sent to the cleaning unit 60. Although a local cleaning device without the pulsation device unit 57 is also found, in this case, the warm water that has entered the flow rate channel adjusting unit 56 is directly sent to the local cleaning nozzle unit 58. Further, the water supply to the cleaning unit 60 of the support table 59a is
In some cases, it is performed directly from the bubble unit 53 without passing through the heat exchanger unit 54 or the flow rate channel adjusting unit 56.

At the time of water supply, the tube 61a between the pulsation device unit 57 and the base 59 of the local cleaning nozzle unit 58 bends as the local cleaning nozzle unit 58 moves forward and backward. Cracks tend to occur over time and cause water leakage. Therefore, a structure is used in which the tube 61a is appropriately loaded with a spring material to prevent bending. Further, the initial shape of the tube 61a is changed to the nozzle unit 58 for local cleaning.
Is retreated and the tube 61a is bent most and the nozzle unit 58 for local cleaning is moved forward to adjust the position of the pulsation device unit 57 in advance so as to have an intermediate shape between the tube 61a and the most pulled shape. The bending of the tube 61a associated with the forward / backward movement of the local cleaning nozzle unit 58 is minimized. Furthermore, the pulsation device unit 57
And a tube 61a provided at the base 59 of the local cleaning nozzle unit 58.
The tube 61a is arranged along a loop line having a substantially elliptical shape formed so as to pass through the connection port of a,
It has been proposed to prevent the tube 61a from largely bending or bending depending on the location as the local cleaning nozzle unit 58 moves back and forth.

[0004]

However, the conventional structure for mounting the nozzle tube for local cleaning as described above has the following problems to be solved. (1) As shown in FIGS. 6 (A) and 6 (B), the distance between the pulsation device unit 57 and the base 59 is shortened and the tube 6
When 1a is curved, there is a restriction in the height direction, which restricts the design of the flush toilet. In addition, the tube 61a hits the toilet body to make a sound, or the tube 61a and the toilet body rub against each other to cause scratches. (2) The tube 61a extends (see FIG. 6 (B)),
Tube 6 generated by bending (see FIG. 6 (A))
If the tube is loaded with a spring material in order to prevent the breakage of 1a, the diameter of the water channel becomes small and the amount of water for cleaning becomes insufficient. (3) A tube 61b connecting the flow rate flow path adjusting unit 56 and the cleaning section 60 of the support 59a, and a bubble unit 53.
The tube 61c connecting between the cleaning section of the support table 59a and the cleaning unit 59a requires a long distance, and the tube itself becomes an obstacle,
Water may remain in the bent and sagging tube, causing breakage due to freezing. The present invention has been made in view of the above circumstances, and prevents the occurrence of defects such as breakage and residual water in a tube that repeatedly stretches and bends, and does not impose design restrictions. An object is to provide a mounting structure for a unit tube.
