Description

  The present invention relates to a faucet intrusion water discharge structure for discharging intrusion water such as hot water entering a main body of a faucet to which a hose is removably attached.

  Conventionally, faucets for accommodating and holding shower devices and the like have been used in sinks and washstands, and in such faucets, a hose connected to a water discharge device such as a shower head is connected to the faucet body. There is also known a hose pull-out faucet that is attached so as to be freely drawn out and can obtain shower watering at a desired position in a sink sink or a wash bowl. In such a faucet, hot water may enter the faucet body from the gap of the faucet opening through which the hose is inserted, and the hot water may hang down along the hose or in the cabinet below the sink or washbasin. There is. In view of this, conventionally, a faucet intrusion water discharge structure has been used, such as providing a discharge port for discharging hot water that is dropped through the hose from the middle of the faucet body.

  As such an intrusion water discharge structure of the faucet, for example, as shown in FIG. 7, a discharge port 60 is formed in the main body 11 of the faucet 10, and the hose 18 is directly connected to the upstream side of the discharge port 60. A device using a draining member 66 comprising a surface material 62 that contacts and has a large number of through-holes on the surface and a water absorbing material 64 such as a sponge layered on the lower surface is known. In this intrusion water discharge structure 68, the intrusion water adhering to the surface of the hose 18 accommodated obliquely in the faucet 10 is removed by the surface material 62 when the hose 18 is taken in and out, and the removed intrusion water is removed. It is absorbed by the water absorbing material 64 and reliably discharged from the discharge port 60. Further, by protecting the water absorbing material 64 with the surface material 62, the water absorbing material 64 is prevented from being worn out by the hose 18 being put in and out (see, for example, Patent Document 1).

JP 2002-364036 A (FIG. 3)

  However, in the intrusion water discharge structure 68 of the faucet 10, as described above, the draining member 66 that is in direct sliding contact with the hose 18 makes the intrusion water on the outer peripheral surface of the hose 18 when the hose 18 is pulled out and stored. Although it can be removed, draining cannot be performed efficiently if the hose 18 is pulled out or the hose 18 is housed. Therefore, the intrusion water that has entered when the water is discharged with the hose 18 pulled out or the intrusion water that flows down in the state in which the hose 18 is housed cannot be sufficiently drained, and is transmitted to the outer peripheral surface of the hose 18. It will flow down to the faucet 10 as it is. In addition, when hot water enters the faucet 10 vigorously, the intruded water jumps over the drainage member 66 and jumps to the side or upper side of the outer peripheral surface of the hose 18, and passes through the outlet 60 to the faucet 10. There is also a risk of flowing down inside.

  The present invention solves the above-mentioned problems of the conventional faucet intrusion water discharge structure, reduces the intrusion water that travels on the outer peripheral surface of the hose, and suppresses the water flow of the intrusion water to jump over the discharge port. It is an object of the present invention to provide an intrusion water discharge structure for a faucet that can reduce inflow and efficiently discharge intrusion water from a discharge port.

In order to solve the above problems, means taken by the present invention will be described below. The faucet intrusion water discharge structure of the present invention is a faucet intrusion water discharge structure for discharging intrusion water that has entered the inside of the faucet body through which the hose is removably inserted. A discharge port is formed in the insertion hole of the main body to be formed, and a rib supporting the hose is formed above the lower portion of the inner peripheral surface of the insertion hole closer to the tip of the insertion hole than the discharge port , a penetration water discharge structure of the faucet, characterized in that the base end portion of the rib is formed lower than the front end portion (claim 1).

  By forming the rib for supporting the hose in the insertion hole as described above, the outer peripheral surface of the hose is positioned above the insertion hole away from the lower portion of the inner peripheral surface of the insertion hole. Therefore, the intrusion water that travels through the hose can be separated from the outer peripheral surface of the hose and dropped downward. In this way, it is possible to reduce the intrusion water that travels on the outer peripheral surface of the hose and efficiently discharge the intrusion water from the discharge port. Also, the inflowing water is diverted to both sides of the rib by the rib, so that the inflowing water dripped from the outer peripheral surface of the hose can be weakened, and the intruding water can be prevented from jumping over the discharge port due to the water force. it can.

In addition, since the rib base end portion in the vicinity of the discharge port is formed lower than the tip end portion of the rib, a gap can be provided between the rib and the hose outer peripheral surface immediately before the discharge port. Here, the distal end portion of the rib refers to a portion on the distal end side in the water discharge port, and the proximal end portion of the rib refers to a portion on the proximal end side in the water discharge port. Therefore, the intrusion water transmitted between the hose and the rib can be easily dropped to the lower portion of the insertion hole by this gap, and the intrusion water can be discharged more efficiently.

  Since the present invention is provided with the ribs as described above, the intrusion water that travels on the outer peripheral surface of the hose is reduced, and the intrusion water that jumps over the discharge port is reduced by suppressing the water flow of the intrusion water. Water can be discharged.

  Next, an embodiment of the ingress water discharge structure for a faucet of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, the faucet ingress water discharge structure 1 is provided on a main body 11 of a faucet 10 installed on a deck surface (not shown) of a sink or a wash basin. A lever handle 13 is attached to the upper part of the body unit 12 of the main body 11, and a water outlet 15 is attached to the vicinity of the center of the side surface of the body unit 12 so as to be rotatable in the horizontal direction. The faucet 10 can adjust the amount of water discharged and the amount of water discharged from the shower head 14 detachably held at the tip of the water discharge port 15 by operating the lever handle 13.

  The shower head 14 is detachably held at the tip opening 16 of the water discharge port 15. The hose 18 connected to the shower head 14 is accommodated and inserted into the insertion hole 20 at the back of the tip opening 16 so that it can be pulled out. By pulling out the shower head 14 together with the hose 18, a sink sink and a wash bowl ( The water discharge from the shower head 14 can be obtained at a desired position in (not shown). And although illustration is omitted, the hose 18 routed below the faucet 10 is hung down below the faucet 10 to a length that can be pulled out. It is connected to a valve device built in the main body 11. Further, the hose 18 is formed of a so-called flexible tube having an outer peripheral surface formed in a bellows shape, and has a certain rigidity and is provided so as to be flexible to some extent, so that the hose 18 can be smoothly drawn out and accommodated. It is configured. In addition, the outer diameter of the hose 18 of this example is provided at about 14 mm.

  The water discharge port 15 is attached with its tip directed obliquely upward from the body unit 12. Moreover, the whole is made into the shape gently curved below as it goes to the front-end | tip. The cross-sectional shape of the water discharge port 15 is formed so as to be tapered toward the tip. Further, as will be described later, the cross-sectional shape of the insertion hole 20 inside the water discharge port 15 is also formed to taper as it goes to the tip, and the tip of the largest diameter portion on the base end side is about 35 mm. It is about 24mm on the side.

  In addition, the first discharge port 22 and the locking hole 24 are arranged in order from the front end side near the front end of the water discharge port 15 at a portion directed to the lower side of the side surface portion of the water discharge port 15 protruding obliquely upward. It has been drilled. A second discharge port 26 is formed near the base end of the water discharge port 15. The first discharge port 22 is formed to discharge the intrusion water that has entered from the tip opening 16 prior to the second discharge port 26. Further, the locking hole 24 is provided to lock a draining member 30 in a water discharge port 15 by locking a locking projection 38 of a draining member 30 to be described later. It is formed in almost the same shape. The second discharge port 26 is formed in the vertical direction with respect to the outer wall of the water discharge port 15 that protrudes in an inclined manner. It is formed so that it can be discharged reliably. Further, a wall portion 50 whose upper portion is cut out in a semicircular shape is provided in a lower portion of the inner peripheral surface of the insertion hole 20 on the rear side of the second discharge port 26. The hose 18 is placed on the upper portion of the wall 50, and the hose 18 is moved on the wall 50 when the hose 18 is pulled out and stored.

  A substantially cylindrical draining member 30 is inserted and fixed in the distal end opening 16 of the water discharge port 15, and the hose 18 is inserted into the water draining member 30 and inserted into the water discharge port 15. A serration 32 is engraved on the outer peripheral surface of the tip of the draining member 30, and when the shower head 14 is held in the water discharge port 15, the shower head 14 is inserted into and connected to the tip of the draining member 30 and showered. Since the serrations 17 on the inner peripheral surface of the base end portion of the head 14 mesh with the serrations 32 on the draining member 30 side, the shower head 14 is prevented from rotating with respect to the water discharge port 15. An opening 34 is formed in the vicinity of the center of the side surface of the draining member 30 that is directed downward while being attached to the water discharge port 15. The opening 34 is disposed at a position facing the first discharge port 22 in a state of being attached in the water discharge port 15, so that the intrusion water passing through the hose 18 is guided to the first discharge port 22 from the opening 34. It is configured. Further, the base end portion of the draining member 30 is provided with a locking piece 36 protruding like a cantilever, and the locking projection 38 provided at the tip of the locking piece 36 is as described above. As described above, it is locked in the locking hole 24 of the water discharge port 15.

  Next, the rib 40 formed in the insertion hole 20 of the water discharge port 15 will be described. As shown in FIG. 1, the rib 40 protrudes upward from the lower portion of the inner peripheral surface of the insertion hole 20 along the longitudinal direction of the insertion hole 20 from the vicinity of the center thereof to immediately before the second discharge port 26. ing. As shown in FIGS. 2 and 3, the rib 40 protrudes from the center of the lower part of the inner peripheral surface of the insertion hole 20 toward the center of the insertion hole 20. The height of the rib 40 from the inner peripheral surface of the insertion hole 20 is about 5 mm. Further, as shown in FIG. 3, the rib 40 is formed in a fan shape opened at an angle of about 20 degrees with a tapered upper end, and the width of the upper end portion 42 is about 2 mm. Is provided. Further, the base end portion 44 having a length of about 6 mm on the second discharge port 26 side of the rib 40 has a height from the inner peripheral surface of the insertion hole 20 of about 2 mm, and is provided at a height of about 5 mm. The height of the rib 40 is lower than that of the front end portion 46 of the rib 40.

  In the infiltration water discharge structure 1 configured as described above, the infiltration water can be efficiently discharged as follows. First, intrusion water that enters the insertion hole 20 from between the tip opening 16 of the water discharge port 15 and the hose 18 flows downward from the outer peripheral surface of the hose 18, and as described above, the opening 34 of the draining member 30. After that, a certain amount is discharged from the first discharge port 22. Infiltration water that does not flow down around the first discharge port 22 but flows down the insertion hole 20 through the outer peripheral surface of the hose 18 or flows into the periphery of the first discharge port 22, but has entered the first discharge port 22. Water further flows down through the insertion hole 20. At this time, as shown in FIGS. 2 and 3, the hose 18 is supported above the insertion hole 20 by the rib 40, and a certain distance is placed from the lower part of the inner peripheral surface of the insertion hole 20. Therefore, the intrusion water that propagates through the lower portion of the hose 18 can drop to the lower portion of the inner peripheral surface of the insertion hole 20 below the hose 18 and can be easily dropped from the outer peripheral surface of the hose 18. As shown in FIG. 3, the intrusion water B thus separated from the hose 18 flows down toward the second discharge port 26 through either side of the rib 40. Further, as shown in FIG. 2, the proximal end side of the rib 40 is a proximal end portion 44 formed lower than the distal end portion 46, and therefore, particularly the upper end portion 42 of the distal end portion 46 and the outer peripheral surface of the hose 18. The intrusion water or the like transmitted between the hose 18 can be easily dropped from the outer peripheral surface of the hose 18 by the gap 48 provided between the base end portion 44 and the outer peripheral surface of the hose 18. At the same time, by providing the base end portion 44, it is possible to prevent the intrusion water on the left and right sides of the rib 40 from joining just before the second discharge port 26 to increase the water force. Then, the ingress water dripped from the hose 18 is discharged from the second outlet 26 to the outside of the outlet 18. Further, the intruding water that jumps over the second discharge port 26 and flows downward through the insertion hole 20 is forcibly guided to the second discharge port 26 by the wall 50.

  In addition, by making the ingress water once divided on both sides of the rib 40 and flowing down toward the second discharge port 26, it is possible to prevent a large amount of intrusion water from collecting and strengthen the water flow, and the intrusion water is prevented from flowing into the second discharge port 26. It is possible to prevent the outlet 26 from jumping over easily. In the case where the wall portion cannot be formed over the entire circumference of the insertion hole 20, such as when the water discharge port 15 has a curved shape, as in the faucet 10 of the present example, which may obstruct the mold removal. Is preferable because it can suppress the inflow of intrusion water from a portion near the upper portion of the insertion hole 20 where the wall portion 50 is not formed. In this way, the intrusion water that has entered the insertion hole 20 can be discharged efficiently.

  Next, another embodiment of the ingress water discharge structure for a faucet of the present invention will be described in detail with reference to the drawings. In addition, about the structure which is common in above-mentioned 1st embodiment, the code | symbol same as 1st embodiment is attached | subjected to a figure, and description is abbreviate | omitted. FIG. 4 shows an intrusion water discharge structure 2 in which two ribs 40 are arranged in parallel in the insertion hole 20. According to this intrusion water discharge structure 2, since the inflow water can be dispersed into three by the two ribs 40, the inflow water flow can be further weakened, and the ingress water is reliably discharged from the second discharge port 26. Can be made.

  Further, in the intrusion water discharge structure 3 shown in FIG. 5, a recess 52 is formed in the upper end portion 42 of the rib 40. According to this intrusion water discharge structure 3, since a gap can be provided between the outer peripheral surface of the hose 18 and the upper end portion 42, it is easy to separate intrusion water that travels below the outer peripheral surface of the hose 18 from the outer peripheral surface of the hose 18. You can also. Similarly, as in the infiltration water discharge structure 4 shown in FIG. 6, a brush 54 is provided at the upper end portion 42 of the rib 40, thereby providing a gap between the outer peripheral surface of the hose 18 and the upper end portion 42. It is possible to make it easier to separate the intrusion water that travels in the lower part of the surface from the outer peripheral surface of the hose 18. Further, the rib itself may be a brush.

  The present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the gist of the present invention. For example, the rib 40 may have other shapes, and the length, thickness, height, and the like can be changed as appropriate. Further, depending on the shape of the water discharge port, the rib 40 can be provided at another part in the insertion hole 20. Further, the rib 40 can be formed separately from the water outlet 15.
