Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an assembling technique in a sanitary washing device for washing a local portion, and more particularly to an upper wiring duct of the sanitary washing device.

[Conventional technology]

2. Description of the Related Art Conventionally, as a sanitary washing device for locally washing a human body, various types of structures such as an anus washing device or an anus washing device and a bidet washing device have been used. Generally, the upper wiring of this type of sanitary washing device connects the control unit provided in the sleeve of the main body, the drive unit and the sensor provided in the center of the main body with a large number of electric wires. Usually, the harnesses that were bundled after assembly were routed around the gaps between the parts for wiring.

[Problems to be solved by the device]

Therefore, in the conventional structure, not only the work such as bundling after wiring and bundling and fixing with a clamp of another member etc. is required so that the harnesses drawn around do not become complicated and come into contact with the movable part, and the bundling part is unwound during maintenance. In addition, there is a problem that workability is poor because it requires work such as rebinding.

The present invention has been made in view of the above problems, and an object thereof is to provide an upper wiring duct of a sanitary washing device which has good workability and a simple structure.

[Means for Solving the Problems]

In order to achieve the above object, the upper wiring duct of the sanitary washing device according to the present invention has a nozzle rod slidably inserted into a nozzle cylinder, and the nozzle rod is moved to a storage position via a reciprocating drive means. In a sanitary washing device provided with a nozzle assembly that is displaced into and out of a washing position and discharges washing water from a protruding nozzle rod end to wash a local portion, a top portion of a support bracket for fixing the nozzle assembly to a main body case. The gist of the invention is to integrally form a thin passage for passing through the harness that electrically connects the control circuit device, the power supply unit, and the drive units. The support bracket may have a structure that includes a guide mechanism that supports the nozzle cylinder so as to be slidable in the axial direction. Further, at least a part of the groove-shaped passage is provided with a retainer that protrudes inward from the upper ends of both side edges. It is desirable to configure the protrusions.

[Action]

In the above-described configuration, the nozzle cylinder that houses the nozzle rod that moves into and out of the storage position, the anal cleaning position, and the bidet cleaning position, which constitutes the cleaning mechanism located in the center of the sanitary cleaning device, can be fixed or retracted. Since the upper wiring duct is formed by a groove-shaped passage integrally formed on the top of the supported support bracket, a harness for electrically connecting the control circuit device section to the power supply section and each drive section is passed through the duct. By urging, the wiring of the internal harness of the apparatus can be arranged, and when replacing the wiring, the desired wiring can be simply removed from the duct.

〔Example〕

An embodiment of an upper wiring duct of a sanitary washing device according to the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a sanitary washing device main body which is located behind a toilet seat 3 placed on the upper surface of the toilet bowl 2 and which is fixedly mounted on the toilet bowl 2. A nozzle assembly 5 that constitutes the mechanism is provided, control circuit portions 6a and 6b formed of electronic circuits are formed on the left and right sleeve portions, and a hot air discharge duct 14 and the like are arranged. The nozzle assembly 5 has sliding ribs 8 and 8 projecting along the nozzle cylinder 7 at horizontal positions on both sides of the nozzle cylinder 7, and the sliding ribs 8 and 8 are provided inside the support brackets 9 and 9a. The support grooves 9 and 9a are tightly integrated with the bolts and nuts 30 by slidably fitting and holding the guide grooves 10 and 10 formed opposite to each other. Further, the rack 11 formed on the rear side wall on the lower surface side of the nozzle cylinder 7 is a pinion mounted on a drive shaft of a cylinder position adjustment control motor 12 such as a synchronous motor or a pulse motor fixedly mounted on one side of the support bracket 9. A nozzle cylinder reciprocating drive unit that meshes with the nozzle 13 and drives the cylinder position adjustment control motor 12 in the forward and reverse directions by a control signal from the control circuit unit to change the bearing position of the nozzle cylinder 7.

A drum 17 axially mounted on a plate strip case 16 having the rear end of the nozzle cylinder 7 integrally formed is wound with a plate strip 18 having one end fixed thereto, and the outer end of the plate strip 18 is attached to the nozzle cylinder. 7 is connected and fixed to the rear end of the nozzle rod 15 which is secretly inserted from the front end of 7 through a seal member. A nozzle position changing control motor 19 such as a synchronous motor or a pulse motor fixedly mounted on the side surface of the plate spring case 16 is formed by mounting the drum 17 on a drive shaft, and the nozzle position is controlled by a control signal from a control mechanism section. Nozzle rod reciprocating drive means for driving the changing control motor 19 in the forward and reverse directions to displace the nozzle rod 15 with respect to the nozzle cylinder 7 and stopping at a predetermined position.

Reference numeral 21 is a cleaning water supply port formed near the tip of the nozzle cylinder 7, and communicates with the anal discharge hole 23 of the nozzle head 22 fixed to the tip of the nozzle rod 15 or the bidet water discharge hole 24. The end portions of the communication passages are secretly connected to each other at a predetermined protruding position of the nozzle rod 15.

The upper wiring duct 20 according to the present invention is integrally formed on the top of one of the support brackets 9 and 9a made of synthetic resin which slidably supports the nozzle cylinder 7 of the nozzle assembly 5. The upper wiring duct 20 is formed by bending at a right angle from the side plate portion 25 of the support bracket 9 to form a passage 26 having a groove-shaped cross section of an appropriate length, and one end side edges 27, 27 of the passage 26. Inwardly protruding pressing projections 28, 28 are provided at the upper end of the so as to have a slight gap 29.

The sanitary washing device having the upper wiring duct 20 having the above-described configuration has a groove-shaped cross section of the harness 31 from the gap 29 of the upper wiring duct 20 when routing various harnesses 31 such as signal cables or power cables. The harness 31 can be put together in the central upper part of the sanitary washing device 1 by dropping it into the passage 26, and the accident that the harness 31 is engaged with the nozzle assembly 5 which is the movable part does not occur. .

[Effect of device]

Since the upper wiring duct of the sanitary washing device according to the present invention is configured as described above, the duct is provided at the top of the support bracket that supports the nozzle assembly that forms the movable part at the center of the sanitary washing device. With this configuration, the harness that electrically connects the control circuit device unit to the power supply unit and each drive unit is routed through the duct, so that the wiring of the internal harness of the device can be organized and the structure is simplified. The present invention has the characteristic that it can be achieved, and the practical effect after implementing the present invention is extremely large.
