Description

  The present invention relates to a faucet provided with a rectifying cap.

  A faucet in which a rectifying cap is screwed into the tip of a water discharge pipe is known. If the faucet is used for a long period of time, foreign matter may adhere to the water spray plate in the flow rectifying cap, resulting in a poor flow, or the water spray plate may be damaged and the rectification performance may deteriorate. In order to clean or replace the watering plate, for example, Patent Document 1 discloses a structure in which irregularities are provided at a predetermined pitch on the circumference of the tube end portion of the rectifying cap. The rectification cap can be removed from the water discharge pipe by preparing an annular dedicated tool having the same pitch as that of the unevenness and rotating the dedicated tool after fitting the unevennesses.

  As another conventional technique, a vertically long groove is provided in the center of the watering plate of the rectifying cap, and a thick object such as a flathead screwdriver or coin is fitted into this groove, and the rectifying cap is rotated and removed. What you can do is known.

  In the rectifying cap described in Patent Document 1, since the water spray plate is closer to the front side than the portion where the tool is fitted, there is a risk that the special tool will damage the water spray plate. Further, even the latter rectifying cap may damage the water spray plate when inserting a flathead screwdriver or coin into the groove. Furthermore, since there is a groove at the center of the watering plate, it cannot be said that the flow straightening is excellent.

  This invention is made | formed in view of such a subject, The objective is to provide the technique which makes it possible to remove a rectifying cap, without damaging the part which rectifies | straightens in the faucet provided with the rectifying cap.

  In order to solve the above-described problem, an aspect of the present invention provides a faucet including a water discharge pipe and a flow straightening cap screwed into the water discharge pipe, the flow straightening cap includes a water flow member, and the water flow member. Is provided on the front side of the water discharge pipe in the axial direction of the water discharge pipe, and at least two concave tool hooks facing the radial direction are provided, and in the diameter direction of the rectifying cap passing through the tool hook, A water discharge surface from which rectified water is discharged is located between the water flow member.

  According to this aspect, there is no possibility of damaging the water passage member when a tool is hung on the tool hanger. Therefore, the rectification property can be maintained even if the rectification cap is repeatedly attached and detached. Further, the rectifying cap can be removed without using a dedicated tool. Furthermore, since there is a water discharge surface between the tool hanging portion and the water passage member, the water discharged from the water discharge surface through the water passage member and the tool hook portion are separated in the radial direction. It is not disturbed by the hanging part.

  A step may be provided between a portion where the tip of the tool contacts when the tool is hung on the tool hanging portion and a surface from which rectified water is discharged. According to this, the water discharge surface is not damaged.

  According to the present invention, in the faucet provided with the rectifying cap, the rectifying cap can be removed without damaging the portion to be rectified.

  FIG. 2 is an overall perspective view of the faucet 10 of FIG. The faucet 10 mainly includes a water discharge pipe 12 and a proximal end portion 14.

  As shown in FIG. 1, the base end portion 14 is disposed on the upper surface of the counter 104 of the kitchen. The water discharge pipe 12 is formed in a so-called gooseneck shape in which an intermediate portion is curved and formed in an inverted U shape, and a tip 18 thereof extends obliquely downward. The water discharge pipe 12 is formed of a casting made of a metal material. The inverted U-shaped portion of the water discharge pipe 12 is formed to have a constant curvature.

  A rectifying cap 20 for rectifying supplied water is screwed into the tip 18 of the water discharge pipe 12 inside the pipe (see FIG. 3). By screwing the rectifying cap into the inside of the pipe in this way, the distal end 18 of the water discharge pipe 12 has the same diameter from the base end portion, and a clean impression can be given.

  Under the base end portion 14, that is, inside the counter 104, a water purification pipe extending from a water purifier (not shown) is connected to a supply hose (not shown) disposed in the water discharge pipe. The other end of the supply hose is connected to the rectifying cap 20 described above. A solenoid valve (not shown) is provided between the water purification pipe and the supply hose. This electromagnetic valve can control the flow of water from the water purification pipe to the water supply hose by opening and closing the valve under the control of a control unit (not shown).

  A hand-holding sensor 16 is provided on the front side of the water discharge pipe 12, that is, the side facing the user standing in the kitchen. The hand-holding sensor 16 is an infrared light quantity sensor having a light emitting part and a light receiving part. The hand-holding sensor 16 projects light obliquely above the sensor 16, receives light reflected from an object to be detected such as a user's hand by the projected light, and receives the light within a predetermined detection area. Detect whether there is an object to be detected. The hand-holding sensor 16 outputs a signal indicating the detection result of the detected object to the control unit.

  The control unit is configured by a circuit board on which a microcomputer is mounted. The control unit opens and closes the electromagnetic valve based on the output signal from the hand-holding sensor 16 to switch the water supply from the water discharge port 19 of the water discharge pipe 12. Note that the control unit may be realized by combining elements and circuits including a CPU and a memory of a computer.

  In the hand-holding sensor 16, once the detected object is detected in the detection area, the water supply from the water outlet 19 is continued even if the detected object is not detected thereafter. When an object to be detected is detected again in the detection area, water supply from the water outlet 19 is stopped.

  FIG. 3 is a schematic cross-sectional view of the tip 18 of the water discharge pipe 12. The rectifying cap 20 is a member that is screwed into the female screw portion 32 formed at the tip of the water supply hose 34. A water passage member 30 is disposed in the flow straightening cap 20, and this water passage member 30 exhibits a flow straightening action. The water that has passed through the water passing member 30 passes through the water pipe 24 and is discharged from the water discharge surface 26. The water flow member 30 is, for example, one or a plurality of circular nets or a water spray plate having a large number of holes.

  4 is a lower perspective view of the rectifying cap 20, and FIG. 5 is a cross-sectional view of the rectifying cap 20. A step 22 for holding the water-permeable member 30 is formed on the axial side of the water discharge pipe 12 of the rectifying cap 20 (upper side in FIGS. 4 and 5). A flange 25 extending to the outer diameter side for defining the screwing amount with respect to the female screw portion 32 is formed on the near side in the axial direction of the water discharge pipe 12 of the rectifying cap 20 (lower side in FIGS. 4 and 5). On the inner diameter side of the flange 25, a water discharge surface 26 from which rectified water is discharged is formed. A male screw 29 is formed on the outer surface of the rectifying cap 20.

  Two concave tool hooks 28 are formed on the flange 25 of the rectifying cap 20 at positions facing the radial direction. As shown in FIGS. 4 and 5, the bottom of the tool hook 28 is not cut to the water discharge surface 26, and a slight step 27 is provided with respect to the water discharge surface 26. Two or more sets of tool hooks 28 may be provided.

  FIG. 6 is a diagram illustrating a state in which the rectifying cap 20 is removed from the water discharge pipe 12. The length of the tip 52 of the tool 50 is slightly shorter than the outer diameter of the flange 25 of the rectifying cap 20. The tip 52 is inserted into the two tool hooks 28 so as to cross the straightening cap 20. Thereafter, the rectifying cap 20 can be removed from the water discharge pipe 12 by rotating the tool 50. Even if the dedicated tool 50 is not used, an object (for example, a flat-blade screwdriver or a coin) whose length is longer than the inner diameter of the flange 25 and whose width is smaller than the circumferential width of the tool hook 28 is used. Thus, the rectifying cap 20 can be removed.

  The tool hooking portion 28 is provided on the near side in the axial direction of the water discharge pipe 12 (the front end side of the water discharge pipe 12) with respect to the water flow member 30 that exhibits the flow straightening action, so that the tool can be removed when the flow straightening cap 20 is removed. There is no risk of damaging the water flow member 30. Therefore, the rectifying property of the rectifying cap can be maintained even when the rectifying cap is repeatedly attached and detached. Further, since the bottom of the tool hook 28 (the part where the tip of the tool contacts) has a step 27 with respect to the water discharge surface 26, the surface of the water discharge surface 26 and the water pipe 24 is not damaged even if a tool is inserted. . In general, when these surfaces are damaged, dust is attached or the flow is partially disturbed, so that the rectification property is impaired. However, such a situation can also be prevented.

  Further, in the diametrical direction of the rectifying cap 20 passing through the tool hooking portion 28, a water discharge surface 26 from which rectified water is discharged is located between the tool hooking portion 28 and the water passing member 30. With this arrangement, the water discharged from the water discharge surface 26 through the water passing member 30 and the tool hook 28 are separated in the radial direction, so that the discharged water is not disturbed by the tool hook.

  As mentioned above, although this invention was demonstrated based on embodiment, embodiment only shows the principle and application of this invention. In the embodiment, many modifications and arrangements can be made without departing from the spirit of the present invention defined in the claims.

  In the embodiment, an automatic faucet using a sensor is illustrated, but a faucet that manually starts water supply may be used.

  The faucet according to the present invention can be used for facilities installed in buildings, ships, and the like, and may be used in a washstand, a hand-washer, a bathroom, etc. in addition to a kitchen. Moreover, although the counter was illustrated as a base | substrate to which the base end part of a faucet is fixed, the base | substrate may be a wall member etc. which divides the inside and outside of facilities, such as a bathroom.

  Moreover, the shape of the water discharge pipe is not limited to the gooseneck shape, and may be formed in other shapes.
