  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that components having the same function are denoted by the same reference symbols throughout the drawings for describing the embodiments, and the repetitive description thereof may be omitted.

  First, in an automatic cleaning apparatus that performs automatic cleaning of a toilet illustrated as a male urinal, from a wall-embedded unit in which a sensor and a valve are disposed in a wall, the sensor and A refurbishment method for refurbishing an external unit in which a valve is disposed will be described.

  As described above, FIG. 1 and FIG. 2 are examples of the conventional automatic cleaning apparatus 2 (2A), and a sensor for detecting a user and a valve that is opened and closed by a signal based on the sensor are arranged in the wall. The wall-embedded unit 3 is provided.

  First, as shown in FIG. 3, a step of removing the front plate 12 having the sensor window of the wall-embedded unit 3 from the conventional automatic cleaning device 2 (2A) is performed (step S1). The front plate 12 is made of metal and has a sensor window 14 at the center, and a sensor 16 for detecting a user is installed on the back surface (inside the wall) of the sensor window 14. In addition, the front plate 12 is normally fixed using the magnet 22 with respect to the frame member 18 currently fixed to the wall surface WL.

  Next, as shown in FIG. 3, a process of removing the control wiring 24 and the power supply wiring 26 connected to the sensor 16 of the wall-embedded unit 3 is performed (step S2). As a result, the front plate 12 and the sensor 16 can be cut off from the wall-embedded unit 3 and removed. Normally, a commercial power supply (AC 100 V) is supplied to the power supply wiring 26.

  Next, as shown in FIG. 4, after closing the stop cock 30 of the main flow path 28 of the wall-embedded unit 3 and taking a fountain prevention measure, the valve is provided in the main flow path 28 and performs water flow and water stop. A step of removing (piston valve 32) is performed (step S3). Here, the main flow path 28 is a flow path that communicates with the water supply pipe 34 shown in FIG. 2, takes water from the water supply pipe 34, communicates with the drain pipe 36, and supplies water to the drain pipe 36. Therefore, by opening and closing the main flow path 28 by the piston valve 32, a flush water stop / water stop action for flowing from the water supply pipe 34 to the toilet 1 via the drain pipe 36 is obtained.

  Next, as shown in FIG. 5, the pressure acting on the piston valve 32 of the wall-embedded unit 3 is changed to operate the piston valve 32 and the electromagnetic valve 42 that opens and closes the sub-flow path 38. A step of removing each of these is performed (step S4).

  Next, as shown in FIG. 6, sealing portions 44, 46, and 48 are attached to the locations where the piston valve 32 of the main channel 28 is removed and the locations where the sub-channel 38 is removed, thereby closing the openings. Thus, a process of making the main flow path 28 a simple flow path having no opening / closing function is performed (step S5). Therefore, the water supply pipe 34 and the drain pipe 36 are connected by the main flow path 28 as a simple flow path (pipe) having no opening / closing mechanism therebetween.

  Next, as shown in FIG. 7, a step of drawing out the wiring 54 for supplying power from the power supply wiring 26 via the adapter 52 is performed (step S6). In this embodiment, the voltage is stepped down using the adapter 52. As a modification, the power supply wiring 26 may be directly pulled out (not shown).

  At this time, as shown in FIG. 8, the wiring 54 passes through the hole-shaped first wiring passage portion 62 of the rear plate 56 and performs a step of drawing out from the wall to the outside (step S7). As a modification, the first wiring passage portion may have a notch configuration (not shown).

  Here, in the present embodiment, a wiring case 64 fixed to the rear plate 56 is fitted on the wiring 54, and the wiring 54 is accommodated inside the wiring case 64. The wiring case 64 is a flexible cylindrical member formed using a resin material, and can be bent and deformed depending on the installation location.

  Next, as shown in FIG. 8, the rear plate 56 is in contact with the left and right side portions of the inner periphery of the frame member 18 in the direction from the inside to the outside of the wall (indicated by the arrow A). The process of arrange | positioning is implemented (step S8). Here, FIG. 9 shows a state where the rear plate 56 is disposed. As a modification, the position where the rear plate 56 contacts may be the upper and lower side portions instead of the left and right side portions (not shown).

  Next, as shown in FIG. 10, after the adapter 52 is housed inside the frame member 18 (that is, in the case member 10), the wiring case 64 fixed to the rear plate 56 is placed on the front side (from the wall to the wall). Pulling outward) maintains the state in which the rear plate 56 is in contact with a predetermined position on the inner periphery of the frame member 18. In this state, while passing the wiring 54 (in this case, the wiring case 64 in which the wiring 54 is stored) through the notched second wiring passage portion 72 of the front plate 66, the front plate 66 is attached to the frame member 18. A step of fitting is performed (step S9).

  Next, as shown in FIG. 11, a step of fixing the front plate 66 and the rear plate 56 with fixing screws 74 is performed (step S10). Accordingly, the front plate 66 and the rear plate 56 can be fixed to the frame member 18.

  Next, as shown in FIG. 12, a step of removing the cleaning tube 76 (see FIGS. 1 and 2) provided downstream of the main flow path 28 of the wall-embedded unit 3 and above the toilet 1. (Step S11).

  Next, as shown in FIG. 13, a sensor that detects the user and a valve that opens and closes the flow path of the cleaning water by a signal based on the detection at the place where the cleaning pipe 76 is removed (both not shown). A step of attaching the external type unit 5 in which is embedded is performed (step S12). More specifically, the intake pipe 84 of the external mold unit 5 is connected to the upstream pipe 82 to which the cleaning pipe 76 is connected, and the external mold unit 5 is connected to the downstream pipe 86 to which the cleaning pipe 76 is connected. The water supply section 88 is connected (here, the extension pipe 90 is used). As an example, with respect to the flow path / valve structure, sensor mechanism, and the like inside the external mold unit 5, the configurations disclosed in JP-A-10-054064, JP-A-11-210046, and the like can be employed.

  In addition, the execution order of step S11 and subsequent step S12 is not limited to immediately after step S10, For example, it is good also as an order of performing at the timing between step S3-step S10.

  Next, as shown in FIG. 13, a step of removing the cap 92 of the external mold unit 5 and connecting the wiring 54 to the drive control unit 94 of the external mold unit 5 is performed (step S13). It is preferable that a hole or a notch be provided in the cap 92 so that the wiring 54 can pass through the cap 92 (not shown).

  The automatic cleaning apparatus 2 (2A shown in FIGS. 1 and 2) including the wall-embedded unit 3 in which a sensor and a valve are disposed in the wall is related to the automatic cleaning apparatus that automatically cleans the toilet bowl through the above steps. It is possible to retrofit the automatic cleaning apparatus 2 (2B shown in FIGS. 14 and 15) including the external mold unit 5 in which the sensor and the valve are disposed at the upper position of the toilet 1 outside the wall.

  At that time, the frame member 18, the main flow path 28, the water supply pipe 34, the drain pipe 36, etc. in the wall-embedded unit 3 can be used as they are. Therefore, the repair work can be simplified and the repair cost can be greatly reduced.

  The automatic cleaning apparatus 2 (2B) including the refurbished external type unit 5 can automatically clean the toilet 1 without any difference from the automatic cleaning apparatus 2 (2A) including the wall-embedded unit 3. Rather, it has an advantage in ease of repair at the time of failure.

  Next, the refurbishment tool 100 used for the refurbishment method will be described in detail.

  As shown in FIG. 10, the refurbishment instrument 100 according to the present embodiment is in contact with a predetermined position (for example, both left and right side portions) on the inner periphery of the frame member 18 in a direction from the inside of the wall toward the outside of the wall, and is prevented from coming off. The elongated rear plate 56, the front plate 66 having a size covering the entire opening of the frame member 18, and the wiring 54 inserted through the rear plate 56 are fitted into the rear plate 56. And a wiring case 64 fixed to the circuit board. As an example, each of the rear plate 56 and the front plate 66 is a plate-like member formed using a metal material. On the other hand, the wiring case 64 is a flexible cylindrical member formed using a resin material. In addition, the cylindrical shape of an integral structure may be sufficient, or the cylindrical shape of the structure which combined several components may be sufficient.

  First, the front plate 66 is provided with a through hole 68 through which the fixing screw 74 is inserted (no screw thread for screwing), and a notched second wiring passage portion 72 through which the wiring 54 passes. ing. Unlike the conventional front plate 12, the front plate 66 is not provided with a sensor window.

  Next, the rear plate 56 is provided with a screw hole 58 having an inner peripheral surface with a screw thread to which a fixing screw 74 is screwed, and a hole-shaped first wiring passage portion 62 through which the wiring 54 passes.

  Further, as shown in FIG. 8, the rear plate 56 has a substantially rectangular shape in which both end portions 56a are in contact with the frame portion 18a in which the holes 20 through which the screws 102 for fixing the frame member 18 to the case member 10 in the wall are inserted are formed. And the notch part 60 which avoids so that the hole 20 may not be obstruct | occluded is provided in the one long side 56b side in the both ends 56a.

  A configuration in which the front plate 66 and the rear plate 56 are fixed to the frame member 18 is realized by the configuration in which the fixing screw 74 inserted through the through hole 68 is screwed into the screw hole 58.

  Next, as shown in FIG. 16 as viewed from the side, the wiring case 64 includes a large-diameter portion 64a having a relatively large diameter (outer diameter) and a small-diameter portion 64b having a relatively small diameter (outer diameter). However, it has the shape which becomes a cylinder shape as a whole by being continued alternately in the longitudinal direction. That is, it is a shape belonging to the “bellows shape” and has flexibility, so that it can be bent and arranged in a required shape.

  Further, the wiring case 64 has a front-rear direction (longitudinal direction) with respect to the rear plate 56 with the retaining rings 104 and 106 fitted to the small-diameter portion 64b at the front position and the rear position 64b with the rear plate 56 interposed therebetween. It is fixed to immovable. Therefore, even when the user of the toilet bowl pulls the wiring case 64 by hand, the movement of the wiring case 64 can be prevented and the breakage of the wiring 54 can be prevented.

  Regarding the front plate 66, the width (width in the left-right direction) of the second wiring passage portion 72 is set to be smaller than the diameter of the large diameter portion 64a of the wiring case 64 and larger than the diameter of the small diameter portion 64b. Is preferred. According to this, the front plate 66 and the wiring case 64 can be fixed in a state where the second wiring passage portion 72 of the front plate 66 is fitted to the small diameter portion 64b of the wiring case 64. The movement prevention and the breakage prevention of the wiring 54 can be performed more firmly.

  By using the above-described refurbishment instrument 100, an automatic cleaning apparatus 2 that includes a wall-embedded unit 3 in which a sensor and a valve are disposed in a wall, with respect to an automatic cleaning apparatus that performs automatic cleaning of a toilet bowl (see FIGS. 1 and 2) 2A) shown can be retrofitted to an automatic washing apparatus 2 (2B shown in FIGS. 14 and 15) including an external unit 5 in which a sensor and a valve are disposed outside the wall and above the toilet 1. Become.

  At that time, the frame member 18, the main flow path 28, the water supply pipe 34, the drain pipe 36, etc. in the wall-embedded unit 3 can be used as they are. Therefore, the repair work can be simplified and the repair cost can be greatly reduced.

  The automatic cleaning apparatus 2 (2B) including the refurbished external type unit 5 can automatically clean the toilet 1 without any difference from the automatic cleaning apparatus 2 (2A) including the wall-embedded unit 3. Rather, it has an advantage in ease of repair at the time of failure.

  As described above, according to the disclosed refurbishment method and the disclosed refurbished apparatus, the wall in which the sensor and the valve are disposed in the wall in the automatic cleaning apparatus that performs automatic cleaning of the toilet illustrated as a male urinal The implantable unit can be retrofitted to an external type unit in which sensors and valves are arranged outside the wall and above the toilet bowl.
