Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for cleaning a human body part.

[0002]

2. Description of the Related Art At present, a washing water discharge port is formed at a tip end and a cleaning water discharge nozzle which is driven forward and backward in a longitudinal direction is provided, and a part of a human body is washed with cleaning water discharged from a discharge port of the cleaning water discharge nozzle. Human body local cleaning devices are widely used. In recent years, there has been an increasing number of cases in which an actuator for switching a flow path (flow path switching motor) is directly mounted on a cleaning water discharge nozzle due to the necessity of miniaturization of a human body local cleaning apparatus.

[0003]

However, when an actuator is directly mounted on the cleaning water discharge nozzle, a water supply pipe and an actuator harness are connected to the cleaning water discharge nozzle, and the cleaning water discharge nozzle is stored and extended. The water supply pipe and the actuator harness bend or extend in different directions, respectively, due to the difference in the position of the water supply pipe. As described above, when the water supply pipe and the actuator harness bend or extend in different directions, the water supply pipe and the actuator harness may come into contact with the peripheral unit of the nozzle unit every time the cleaning water discharge nozzle operates. As a result, a space is required near the washing water discharge nozzle so that the water supply pipe and the actuator harness do not come into contact with other units even when bent or extended, which is one of the obstacles in downsizing the human body local cleaning device. I was

[0004]

In order to solve the above problems, in the present invention, a water supply pipe 61 mounted on a nozzle 37 and an actuator harness 44 are inserted into a flexible tube (coiled tube) 31 which can be bent. By bundling one, the water supply pipe 61 and the actuator harness 44 can be bent or extended in one direction when the nozzle is stored or extended. In addition, by making the shape of the flexible tube (coiled tube) 31 appropriate, the bending direction of the flexible tube (coiled tube) 31 in which the water supply pipe 61 and the actuator harness 44 are bundled together is set. Since the control can be performed in an appropriate direction, these tubes do not bend greatly around the nozzle unit, so that they do not interfere with other units. Further, since the space in which the tube between the nozzle unit and the other peripheral unit bends can be designed to be minimized, the downsizing of the human body local cleaning device can be realized.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is an external view of a cleaning water discharge nozzle according to an embodiment of the present invention. The nozzle 37 can be stored and extended back and forth in the longitudinal direction, and the extension movement distance is indicated by the nozzle extension distance 41. The nozzle 37 is provided with an actuator (flow path switching motor) 34 for selecting a plurality of water discharge holes (not shown) provided at the nozzle tip. This actuator (flow path switching motor)
One end (actuator side) 36 of an actuator harness 44 is connected to 34, and the other end of the actuator harness 44 passes through the inside of a flexible tube (coiled tube) 31 and controls a nozzle unit and the like (illustrated in FIG. None). A water supply pipe 61 for supplying cleaning water to the nozzle 37 is connected to a water supply connection pipe (elbow) 35, and similarly passes through the inside of the flexible tube (coiled tube) 31 to the heat exchanger 5. It is connected. Next, the case where the nozzle 37 extends from the storage position will be described. When the nozzle 37 extends from the housed state, it advances by a distance indicated by the nozzle extension distance 41. The nozzle position at this time is indicated by a dotted line at the nozzle position 40 when the nozzle 37 extends forward. At this time, the flexible tube (coiled tube) 31 that bundles the actuator harness 44 of the actuator (motor for switching the flow path) 34 mounted on the nozzle 37 and the water supply pipe 61 also bends in accordance with the extension of the nozzle 37. I do. The extended position of the flexible tube (coiled tube) 31 is indicated by a dotted line 62. At this time, since the flexible tube (coiled tube) 31 is set to an appropriate length and a bending ratio, the flexible tube (coiled tube) 31 is bent without difficulty to the position of the bending position 62 during washing. Therefore, the influence on other units can be minimized.
Further, when the flexible tube (coiled tube) 31 is formed of a spring-like member, the bending rate can be easily controlled by the number of turns of the spring. In particular, if a coil spring having a dense end portion and a sparse central portion is used, the bending rate is increased, and the coil spring is less likely to be displaced from the water supply pipe 61 and the harness 44. Although not shown, when the flexible tube (coiled tube) 31 is formed of a transparent member, the flexible tube (coiled tube) 3 is formed.
Since the state of the water supply pipe 61 and the harness 44 bundled in 1 can be checked at a glance, it is possible to minimize an assembly error in production and the like. The material of the flexible tube (coiled tube) 31 should conform to the present invention even if opaque members or members having holes in a part of the tube are changed according to other circumstances. Needless to say.

FIG. 2 is an exploded view of a cleaning discharge nozzle of the human body local cleaning apparatus of FIG. An actuator (flow switching motor) 34 is attached to the nozzle 37, and the actuator harness 44 is inserted into the flexible tube (coiled tube) 31. Similarly, a water supply pipe 61 for supplying water to the nozzle 37 has a water supply connection pipe (elbow) 35 on the nozzle side.
The water supply side 32 is inserted into a flexible tube (coiled tube) 31. The nozzle 37 is supported by a nozzle support 47 and extends forward and backward through a nozzle support member 46.

FIG. 3 is an external view of a human body local cleaning apparatus according to an embodiment of the present invention. When the user sits on the toilet seat 11 and instructs the operation using the auxiliary operation unit 6 or a remote controller (not shown), the washing water is discharged from the nozzle 37 to wash the local part of the user. After passing through the valve unit 4 and being heated to hot water by the heat exchanger 5, the hot water is supplied to the nozzle 37, and the hot water is discharged from the nozzle tip. Further, the human body detection sensor 1 detects that the user has approached the human body local cleaning device, and the toilet seat opening / closing unit 3 and the toilet lid opening / closing unit 9 are appropriately operated to automatically open and close the toilet seat 11 and the like. After the user's local cleaning, the drying unit 7 can blow warm air to dry the wet local part. In addition, when the user is sitting on the toilet seat 11 using the seat sensor 2, the deodorizing unit 8 operates to deodorize the odor in the toilet and to keep the inside of the toilet comfortable. The nozzle 37 is usually housed in the casing of the human body cleaning device. Since the plurality of functional members are housed in the casing, the inside of the casing is dense with the functional members, and the dead space inside the casing is limited. Therefore, by bundling and moving the water supply pipe 61 and the actuator harness 44 with the flexible tube (coiled tube) 31 when the nozzle extends, it is possible to prevent interference with other functional members (peripheral units).
