[Industrial applications]

 The present invention relates to an improvement of a sensing type flash valve in which an automatic cleaning part is attached to an existing manual type flash valve mounted on a wall surface and is covered with a case.

[0002]

[Prior art]

 Conventionally, the existing manual flash valve is composed of a sensing unit that senses the presence of the user, a control unit that controls the opening and closing of the solenoid valve based on the signal of this sensing unit, and a battery that is the power source for these. There is one shown in Fig. 5 in which the washing water is automatically discharged when the user stands in front of the urinal by installing the automatic washing section. To briefly explain about FIG. 5, the flash valve 40 in which the supply pipe 41 is connected to the urinal A fixes the substrate 44 by fastening a plurality of screws 43, 43 to the lid 42, The back plate 45 is fastened to the vertical portion 44a facing the wall surface B of the board 44 with the screws 43a and 43a, and the battery case 46 for accommodating the battery as the power source is fixed to the back plate 45, and the flash valve 40 A solenoid valve 48 is attached to a bypass pipe 47 connecting the pressure chamber 40a and the supply chamber 40b, and a sensing unit and a control unit are fixed to a box (not shown) covering the flash valve 40, the battery case 46 and the solenoid valve 48. It has been done.

In the above, the case consisting of the back plate and the box is attached to the lid of the flash valve via the substrate, but the flash valve is not parallel to the urinal as shown in FIG. If it is installed in a state that it is tilted to either the left or right, the case and the back plate as well as the flush valve can only be installed in a tilted state, and the appearance is poor and the aesthetics are impaired.

[0004]

[Problems to be solved by the device]

 The problem to be solved by the present invention is a sensing type flash valve in which an automatic flushing unit is attached to an existing flush valve and covered with a case, even if the flush valve is installed in a state inclined with respect to the urinal. The case that covers the flush valve and the automatic cleaning part should be installed in a normal position parallel to the urinal without being restricted by this inclination.

[0005]

[Means for Solving the Problems]

 The present invention fixes a substrate to the lid of an existing flush valve that discharges a fixed amount of cleaning water by manually operating a button, and attaches a case consisting of a back plate and a box facing the wall surface to the flush flash. The valve covers the inside of the case, which connects the sensing unit that senses the user, the control unit that controls the opening and closing of the solenoid valve based on the signal of the sensing unit, and the pressure chamber and the water discharge chamber of the flush valve. In the sensing type flash valve that houses the solenoid valve attached to the bypass pipe and the automatic cleaning part consisting of the battery case that houses the battery for these power sources, either the vertical part of the board or the back plate A pair of small holes are drilled in the vicinity of both left and right ends, and a pair of vertically elongated arcuate guide holes that overlap the small holes are opened in the other end, and screws are inserted into the guide holes and small holes. By tightening It is obtained by allowing attachment to adjust the scan in the horizontal direction.

[0006]

[Action]

 After fixing the board to the lid of the flash bulb, stack the board so that the small holes of the board and the guide holes of the back plate or the guide holes of the board and the small holes of the back plate are aligned and the back plate is flat against the urinal. Adjust the position so that each screw will fasten the back plate to the board, and then attach the box to the back plate.
