It is a perspective view which shows the faucet device 1 in the Example of this invention. 1 is an exploded perspective view of a faucet device 1 according to an embodiment of the present invention. It is AA sectional drawing in FIG. It is the schematic diagram which looked at the faucet device 1 in the Example of this invention from the front.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a state in which the faucet device 1 according to the embodiment is attached to a back guard 6 of a wash bowl (not shown).

  The faucet device 1 is mainly composed of two parts, an operation part 2 and a water discharge part 4. The water faucet device 1 is configured to operate water discharge water from the water discharge unit 4 by rotating the operation unit 2.

  FIG. 2 shows an exploded perspective view of the faucet device 1 in the embodiment. The faucet device 1 is configured by attaching an operation part 2 to a faucet body 8 having a water discharge part 4. The back guard 6 is provided with an operation portion attachment hole 62 and a water discharge portion attachment hole 64 for attachment. A water supply pipe from a building pipe is connected to the water supply connection portion 88 of the faucet body 8 to supply water to the faucet device 1. The faucet body 8 has a cylinder valve 82 fixed therein by screwing a valve retainer 84 into a threaded portion 86. By controlling the cylinder valve 82 indirectly, water discharge / water stop from the water discharge section 4 is controlled. The water discharger 4 is configured by inserting a foam cap 44 into the spout 42.

  The fixing member 24 is disposed on the front side of the back guard 6, and the faucet body 8 is disposed on the rear side, and fastened to the bolt hole 90 through the fixing member through hole 242 by the bolt member 26. The faucet body 8 is fixed to the wash bowl in such a manner that the back guard 6 is sandwiched by the body 8. By disposing the faucet body 8 on the back side of the bag guard 6 in this manner, the forward dimension of the faucet device 1, that is, the protrusion of the back guard 6 to the front side can be suppressed. Further, since the faucet body 8 can be fixed to the wash bowl on the front side of the back guard 6, the back guard can be fixed to the back bowl of the back guard 6 rather than the back guard 6. The space on the rear side of 6 can be narrowed. Therefore, the whole wash bowl to which the faucet device 1 is attached can be made compact.

  The handle member 22 is attached from the front side of the fixing member 24. The handle member 22 is screwed to the lever 822 of the cylinder valve 82 by a bolt member 28. Thereby, by operating the handle member 22, the cylinder valve 82 can be indirectly operated to control the water discharge and water stoppage. Here, the front side is referred to as “front” and the back side is referred to as “rear” as viewed from the user standing in front of the wash bowl (not shown) facing the faucet device 1.

  The handle member 22 is provided with a handle through hole 224 so that the bolt member 26 can be approached from the front side of the handle member 22. As a result, the bolt member 26 can be easily tightened without removing the handle member 22. The handle member 22 is provided with a blindfold member 222 so that the bolt member 26 is not exposed to the external appearance in a normal use state. Further, an O-ring is attached to the blindfold member 222 so that the handle member 22 does not easily fall off. Therefore, by providing the blindfold member 222, it is possible to improve the design, and it is possible to prevent the bolt member 26 from being loosened carelessly due to malice or negligence.

  AA sectional view in FIG. 1 is shown in FIG. As described above, the faucet device 1 is fixed to the wash bowl with the back guard 6 sandwiched between the faucet body 8 and the fixing member 24. At this time, a valve through hole 244 into which the valve presser 84 is inserted is formed in the fixed member 24, and the inner diameter thereof is formed larger than the outer diameter of the valve presser 84. Thereby, it becomes possible to remove the valve presser 84 from the front side with the fixing member 24 attached. That is, maintenance (inspection, replacement, etc.) of the cylinder valve 82 is possible without removing the faucet body 8.

  The arrows shown in FIG. 3 indicate the flow of water. The water supplied from the water supply connection part 88 enters the inside from the bottom of the cylinder valve 82. The cylinder valve 82 is composed of an inner cylinder and an outer cylinder, and a communication hole vacated on the side surface of the inner cylinder and a communication hole vacated on the side surface of the outer cylinder when the inner cylinder accommodated in the outer cylinder rotates. Are connected or disconnected. Thereby, it is a mechanism which adjusts water discharge, water stop, and flow volume. As the cylinder valve 82, a known cylinder valve such as that described in JP-A-2008-215626 can be used as appropriate.

  The water flow adjusted by the cylinder valve 82 passes through the flow path inside the faucet body 8 and reaches the water discharger 4. The tip of the water discharge section 4 has a structure in which a foam cap 44 is attached to the inside of the spout 42, and the foam cap 44 becomes foam spout water in which air is mixed into the water flow to discharge water. At this time, an O-ring 46 is interposed between the water discharger 4 and the back guard 6, so that water does not enter the back side of the back guard 6 even when water is applied to the water discharger 4. It has become. In addition, since the O-ring 46 is interposed between the water discharger 4 and the back guard 6, even if the bolt member 26 is mistakenly removed, the water discharger 4 is discharged from the water discharger mounting hole 64 of the back guard 6 by the O-ring 46. Therefore, the faucet body 8 can be prevented from dropping from the back guard 6.

  The schematic diagram which looked at the faucet device 1 which removed the blindfold member 222 in FIG. 4 from the front side is shown. FIG. 4A shows the water faucet device 1 in a water stop state. In the water stop state, the bolt member 26 can be approached through the handle through hole 224 provided in the handle member 22. At this time, the handle through-hole 224 may have at least an inner diameter into which a tool for tightening the bolt member 26 can be inserted. In the present embodiment, by configuring the bolt member 26 to have an inner diameter larger than the outer diameter of the bolt head, it is possible to construct or remove the bolt member 26 from the front side through the handle through hole 224. It is said. On the other hand, by designing the inner diameter of the handle through-hole 224 to be smaller than the outer diameter of the screw head of the bolt member 26, it is possible to design the bolt member 26 so that it is not inadvertently removed.

  Thus, by arranging the handle through hole 224 and the bolt member 26 to communicate with each other at the water stop position, particularly at the operation limit position of the handle member 22, the position of the handle member 22 when performing the operation becomes easy to understand. .

  FIG. 4B shows a state where the handle member 22 is rotated in the water discharge direction. By rotating the handle member 22 in the right direction on the paper surface, the water discharge from the water discharge unit 4 can be started by indirectly operating the cylinder valve 82. At this time, the handle through hole 224 moves to a position where the bolt member 26 is not exposed. With this configuration, when the bolt member 26 is operated, it is possible to always perform the work in a water-stopped state. On the other hand, by disposing the handle through hole 224 and the bolt member 26 so as to communicate with each other only when the handle member 22 is rotated to the water discharge position, water stoppage is performed upstream of the faucet device 1 during operation. It is also possible to prevent the accident that water is ejected even if the bolt member 26 is rotated in the opposite direction and the bolt member 26 is dropped.

In the above embodiment, the cylinder valve is exemplified as the valve member. However, the valve member is not limited to the cylinder valve, and various valves such as a single lever cartridge can be used. Further, the handle member is not necessarily a rotation operation, and depending on the combination with the internal valve member, the water discharge / water stoppage and the flow rate may be controlled by an up / down operation or a push-in operation.
Further, in the above embodiment, the faucet device is a so-called single faucet connected only to the cold water supply pipe, but it is also connected to the hot water / cold water supply pipe and the water faucet capable of adjusting the temperature. Good. Moreover, you may comprise so-called hot water spout connected with only the piping of warm water, or the suitable temperature spout supplied with the appropriate temperature hot water.

  Although the back guard of the wash bowl is illustrated as the attachment surface of the faucet device, the attachment of the faucet does not have to be a vertical surface, and the present invention can be applied to attachment of a horizontal surface or an inclined surface. Moreover, although it has comprised so that an operation part and a water discharge part may each appear on a mounting surface independently, you may provide an operation part and a water discharge part integrally. The water discharge form can be selected as appropriate from various water discharge forms such as rectified water discharge and shower water discharge instead of foam water discharge, and a plurality of water discharge forms may be switched. Moreover, it is possible to design appropriately within the range which does not deviate from this invention, such as forming the water discharging part so that drawing is possible.
