Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a control device in which a device for sensing a user and automatically controlling the start and stop of water discharge from a faucet is embedded in a wall surface.

[Conventional technology]

2. Description of the Related Art Conventionally, systems have been employed, for example, in flush toilets, wash basins, etc., that detect the presence of a user and automatically discharge water from a flush valve or faucet for supplying flush water. Faucet control devices commonly used for such systems are often built into a wall or suspended from a ceiling.

For equipment that is buried in a wall, it is necessary to expose the front side of the photoelectric sensor body into the wall. For this reason, for example, at a site where the surrounding area is tiled, a flange that matches the joints of the tiles is usually integrated into the sensor body. The flange may be fixed to a support mechanism provided in the wall by mechanical means such as screws, or may be made detachable from the sensor body using other means.

[Problem that the invention attempts to solve]

However, such faucet control devices are often installed especially in buildings, public facilities, etc., with one purpose being to prevent washing water from being wasted. In this case, if the flange that integrates the sensor main body has a large opening, it stands out and the built-in components are expensive, so theft is quite common. The damage is particularly great for sensors whose main body can be taken out from inside the wall.

Additionally, if the flange is large, there are restrictions on the shape of the surrounding tiles in order to match the joints. Therefore, when embedding tiles according to their intended purpose, it is necessary to select the size of the tiles depending on the panel, which reduces the degree of freedom in construction.

Therefore, an object of the present invention is to reduce the mounting width of the sensor body to prevent theft and to enable construction without imposing any restrictions on the size of the tiles.

[Means for solving problems]

In order to achieve the above object, the present invention provides a wall-embedded faucet control device that detects the user and controls water supply to the faucet using a photoelectric sensor body, in which the sensor is mounted on the back side of the wall. A support frame into which the main body is inserted is fixed, a magnet is provided at the back end of the support frame, and a magnet that is attracted to the magnet of the support frame is attached to the back of the sensor main body which is inserted through a mounting opening provided in the wall. It is characterized by being equipped with a suction plate made of wood.

〔Example〕

Hereinafter, the features of the present invention will be specifically explained with reference to embodiments shown in the drawings.

Fig. 1 is a vertical cross-sectional view of a faucet control device according to an embodiment of the present invention when it is embedded in a wall, Fig. 2 is a cross-sectional view of the same, and Fig. 3 is an exploded perspective view of each component. It is.

A tile A is attached to a wall material B such as a Keikal board that partitions the wall of the building, and a mounting hole a for a faucet control device is opened in the center of the tile A. A photoelectric sensor body 1 is stored in and out of the mounting opening a, and the sensor body 1 is stored in the space on the back side of the wall material B.
A support mechanism section is arranged.

The support mechanism section is mainly composed of a support frame 2 fixed to the back surface of the wall material B using an adhesive or the like.

As shown in FIG. 3, the support frame 2 is provided with a flange 3 on the front surface that is large enough to include the tile A, and the flange 3 has an insertion hole in the center with an opening area through which the sensor body 1 can be freely inserted. 4 have been established. In addition, in this flange 3, a hole 6 is opened for a screw 5 for connecting a decorative cover, which will be described later.
A pair of support arms 7 are protruded rearward from the back side, sandwiching the right and left sides of the insertion hole 4. The tip of the support arm 7 has an inwardly bent shape, and a female threaded hole 8 is formed in the center thereof.

Furthermore, a sensor stand 9 which also serves as a decorative cover is connected to the front of the flange 3 by screws 5 passed through holes 6. This sensor stand 9 is formed in the shape of a frame with an opening 9a through which the sensor body 1 can be inserted, and is arranged so that the rim 9b at the edge overlaps the surface of the tile A around the mounting opening a. In addition, the opening 9a
A stepped portion 9c is formed on the inner periphery of the sensor body 1, and the flange 1a provided at the front end of the sensor body 1 is received by this stepped portion 9c.

The sensor body 1 inserted through the opening 9a of the sensor stand 9 is attached to the support frame 2 using the attraction force of the magnet.
Fixedly supported. For this reason, the rear end of the sensor body 1 is equipped with an attraction plate 10 made of a magnetic material, and the support frame 2 has a magnet 1 that receives the attraction plate 10.
Place 1.

The suction plate 10 is supported by an adjuster 13 that is screwed into a bolt shaft 12 provided on the back of the sensor body 1. This adjuster 13 has a female thread 13a screwed onto the bolt shaft 12 and a bolt portion 13b screwed onto the suction plate 10 formed coaxially on the rear end side. to wear Further, a lock nut 14 is screwed onto the bolt shaft 12 to fix the position of the adjuster 13.

On the other hand, the magnet 11 that biases the attraction plate 10 is held by a holder 15 connected to the rear end of the support arm 7. The holder 15 is connected to the support frame 2 by screwing a screw 16 into a female screw hole 8 provided in the support arm 7, and has two upper and lower recesses 15a formed on the front surface for fixing the two magnets 11 in a fitted state. are doing.

In addition, after embedding the support frame 2 in the wall surface,
Insert the sensor body 1 into this, and insert the flush valve D of the flush toilet C, for example, as shown in FIG.
Use it for your own purposes. At this time, the sensor main body 1 senses the presence of the user and inputs the signal to the electromagnetic valve E provided in the piping to the flush valve D. For such a control system, necessary wiring F is provided between the sensor body 1 and the electromagnetic valve E.

The construction procedure for the faucet control device in this example is as follows.

First, the holder 15 holding the magnet 11 is integrated with the support frame 2, and the flange 3 is fixed to the back surface of the wall material B by adhesive or welding. At this time, the tile A is accurately positioned so that it is concentric with the mounting hole a of the tile A provided on the front surface of the wall material B. Next, the sensor stand 9 is positioned in the mounting hole a of the tile A and connected and fixed to the support frame 2 using the screws 5. Note that all of these operations are performed on the back side of wall material B.

The sensor body 1 is fixed by inserting its rear end side through the opening 9a of the sensor stand 9 and attracting the attraction plate 10 to the magnet 11 of the holder 15. At this time, by loosening the lock nut 14 and rotating the adjuster 13 around the bolt shaft 12, the position of the suction plate 10 can be changed and the position can be adjusted. Therefore, the flange 1a of the sensor main body 1 can be set in a state where it fits onto the stepped portion 9c of the sensor stand 9. Incidentally, after the sensor body 1 is set, the wiring F and the like are connected from the back side of the wall material B.

In the above configuration, when the sensor main body 1 is buried and fixed in the wall surface, an adsorption plate is provided on the back of the sensor main body 1, which is attracted and supported by the magnet 11 of the support frame 2. It can be made so that the sensor main body 1 can pass through. Therefore, compared to the conventional case where the flange portion is inserted and fixed into the wall surface, the installation width can be made smaller. Therefore, it is possible to carry out the construction as if it were contained within one tile A, and a good construction body can be obtained without disturbing the joints of the tile A. Further, as long as the tile can be formed with the mounting hole a, it can be constructed regardless of the size of the shape, and installation can be done according to the conditions at the installation site. Then, the sensor body 1 is
Since the sensor body 1 is double surrounded by the tile A and the sensor stand 9 which also serves as a decorative cover, increasing the sense of unity, the sensor body 1 feels as if it cannot be removed, and the effect of preventing theft is improved.

In the above embodiments, the case where the system is attached to a water supply system to a flush toilet has been described, but it goes without saying that it can also be used to control a water supply faucet to a washbasin in a communal toilet or the like.

[Effect of idea]

As explained above, in the faucet control device of the present invention, a support frame for fixing and holding the sensor body is provided on the back of the wall material, a magnetic adsorption plate is attached to the back of the sensor body, and this adsorption plate is attached to the back of the sensor body. The connection is made using a magnet provided on the back side of the support frame. Therefore, since it is only necessary to open an opening in the wall surface that is large enough to allow the sensor body to be inserted, the frontage can be made significantly smaller than that of conventional products. Therefore, it is possible to install the sensor body by drilling a hole in a single tile, and construction with an excellent appearance can be achieved without disturbing the joints of the tiles. Furthermore, if the shape of the tile is such that holes for mounting can be made without being affected by the size of the sensor body, various types of tiles can be used, and construction suitable for the installation site becomes possible.
