JP 2002-228040 A

  By the way, in the water discharging device that inserts the internal flow path member into the outer shell member, since a part of the flow path is formed between the outer shell member and the inner flow path member, the outer shell member contains a harmful metal such as lead. When formed from an alloy, it may not be possible to comply with the elution regulations that are becoming stricter worldwide.

  Therefore, the present inventors have devised a structure in which the elution of the metal component from the outer member is suppressed by completing the flow path with the resin internal flow path member. In a water discharge device that does not allow water to flow between the outer member and the inner flow member, the inner flow member can be inserted into the outer member without providing a seal member or the like between the outer member and the inner flow member. it can.

  However, in such a water discharging device, the position of the internal flow path member is not fixed with respect to the outer shell member. Therefore, there is room for improvement in improving the assemblability.

  An object of one embodiment of the present invention is to provide a water discharge device that improves assemblability.

  By inserting the insertion member in a direction that intersects the insertion direction of the internal flow path unit, when assembling the water discharge device, the position of the internal flow path unit with respect to the outer member can be fixed, and the assemblability is improved. be able to.

  Further, the insertion member is a connection member that allows water or hot water to flow into the internal flow path.

  When the water discharge device is assembled by using the insertion member as a connection member for flowing water or hot water, the position of the internal flow path unit with respect to the outer shell member can be reduced without using another fixing member that is not a part of the water discharge device. Can be fixed.

  Further, the internal flow path includes a hot water flow path through which the hot water flows, and a water flow path through which the water flows, and the insertion member includes a first flow path through which the hot water flows into the hot water flow path. It is characterized by including a connecting member and a second connecting member that allows the water to flow into the water flow passage.

  When assembling the water discharging device, the position of the internal flow path unit can be fixed using the first connection member and the second connection member, and the position of the internal flow path unit can be more fixed with respect to the outer member. it can.

  According to one aspect of the embodiment, assemblability can be improved.

  The water discharge device 1 includes a faucet main body 2, a temperature adjustment handle 3, a flow rate adjustment handle 4, an internal flow path unit 5, a water discharge pipe 6, and a hand shower (not shown). The water spouting device 1 spouts water, such as a mixture of water and hot water, or water from the spout 6 or a hand shower.

  The faucet main body 2 has a cylindrical shape and extends in the left-right direction. The faucet main body 2 is formed of a metal member. On the faucet main body 2, an inner peripheral wall 2a having a circular cross section orthogonal to the left-right direction is formed. The axial direction of the faucet main body 2 coincides with the left-right direction. The external shape of the faucet main body 2 is not limited to a cylindrical shape, and may be, for example, a rectangular shape. The faucet main body 2 forms an outer shell member.

  The internal flow path unit 5 is inserted into the faucet body 2 in the left-right direction. That is, the insertion direction of the internal flow path unit 5 coincides with the left-right direction. A first insertion hole (not shown) for attaching the water discharge pipe 6 to the internal flow path unit 5 from below is formed in the faucet body 2 near the center in the left-right direction. In the faucet body 2, a second insertion hole 2b for attaching the shower hose 7 to the internal flow path unit 5 from the rear is formed near the center in the left-right direction.

  In the vicinity of the left end of the faucet main body 2, a hot water supply pipe 8 is attached from behind via a joint 10, and a third insertion hole 2c is formed. The first connection member 18 that supplies hot water from the hot water supply pipe 8 is inserted into the third insertion hole 2c. In the vicinity of the right end of the faucet body 2, a water supply pipe 9 is attached from the rear via a joint 11, and a fourth insertion hole 2d is formed. A second connection member 19 for supplying water from the water supply pipe 9 is inserted into the fourth insertion hole 2d.

  A temperature adjustment handle 3 is attached to the left end of the faucet body 2. At the right end of the faucet body 2, a flow rate adjusting handle 4 is attached.

  The temperature adjustment handle 3 is rotatably attached to the faucet body 2. The temperature adjustment handle 3 switches the type of fluid discharged from the water discharge pipe 6 or the hand shower to water or mixed water in accordance with the rotational position. Specifically, the temperature adjustment handle 3 switches whether or not to mix hot water with water. The temperature adjustment handle 3 sets the temperature of the mixed water according to the rotation position when the mixed water is discharged from the water discharge pipe 6 or the hand shower.

  The flow adjustment handle 4 is rotatably attached to the faucet body 2. The flow adjustment handle 4 switches the water or mixed water discharge destination to the water discharge pipe 6 or the hand shower according to the rotation position. Further, the flow rate adjusting handle 4 adjusts the flow rate of water or mixed water discharged from the water discharge pipe 6 or the hand shower according to the rotation position.

  Here, the internal flow path unit 5 will be described with reference to FIGS. FIG. 4 is an exploded perspective view of a part of the internal flow path unit 5.

  The internal flow path unit 5 is a unit that allows water supplied from the water supply pipe 9 to flow without flowing between the faucet main body 2 and the internal flow path unit 5. That is, the internal flow path unit 5 is a unit in which the flow path is completed inside. The internal flow path unit 5 includes an internal case 15, a temperature adjustment mechanism 16, and a flow rate adjustment mechanism 17.

  The inner case 15 houses a temperature adjustment mechanism 16 and a flow rate adjustment mechanism 17. The inner case 15 is formed in a substantially cylindrical shape in accordance with the inner peripheral wall 2a of the faucet main body 2.

  A first insertion hole 15a is formed in the inner case 15 at the left rear side. The first connection member 18 that supplies hot water from the hot water supply pipe 8 is inserted into the first insertion hole 15a. A second insertion hole 15b is formed in the inner case 15 at the right rear. A second connection member 19 that supplies water from the water supply pipe 9 is inserted into the second insertion hole 15b.

  The internal case 15 has an internal flow path 20 through which water, hot water, or mixed water flows. The internal flow path 20 is a flow path for discharging water or mixed water from the water discharge pipe 6 or the hand shower without flowing water between the internal flow path unit 5 and the faucet main body 2. The internal flow path 20 includes a hot water flow path 21, a water flow path 22, and a water discharge path 23.

  The hot water supplied from the hot water supply pipe 8 flows through the hot water flow path 21 via the first connection member 18. The hot water flow passage 21 is formed by the inner case 15, the second support case 36 of the temperature adjustment mechanism 16, the valve 30 of the temperature adjustment mechanism 16, and the isolation wall 37.

  The water supplied from the water supply pipe 9 through the second connection member 19 flows through the water circulation channel 22. The water flow path 22 is configured by a first flow path 22a, a second flow path 22b, and a third flow path 22c.

  The first flow path 22 a is formed by the inner case 15 and the support case 42 of the flow rate adjusting mechanism 17, and water flows in from the second connection member 19.

  The second flow path 22b communicates with the first flow path 22a and the third flow path 22c. The second flow path 22b is formed by a concave portion 15c formed near the center in front of the inner case 15, and a lid 15d that covers the concave portion 15c. A seal member 60 is provided between the lid 15d and the recess 15c.

  The lid 15 d is pressed by the inner peripheral wall 2 a of the faucet main body 2 when the internal flow path unit 5 is inserted into the faucet main body 2. Therefore, even when water flows into the second flow path 22b and the water pressure in the second flow path 22b increases, the lid 15d is restricted from moving forward by the inner peripheral wall 2a. Therefore, it is possible to prevent the occurrence of water leakage from the second flow path 22b.

  The second flow path 22b communicates with the first flow path 22a through a first flow hole 15e formed on the right side, and water flows in from the first flow path 22a. The second flow path 22b communicates with the third flow path 22c through the second flow hole 15f formed on the left, and allows water to flow into the third flow path 22c.

  The third flow path 22 c is formed by the inner case 15, the first support case 35 of the temperature adjustment mechanism 16, the valve 30 of the temperature adjustment mechanism 16, and the isolation wall 37. The third flow path 22c is formed so as to be adjacent to the hot water flow path 21 across the isolation wall 37 in the left-right direction.

  The water discharge channel 23 is formed by the first support case 35 and the second support case 36 of the temperature adjustment mechanism 16 on the radially inner side of the inner case 15 than the hot water flow channel 21 and the water flow channel 22. . The water discharge channel 23 communicates with the third channel 22c of the water circulation channel 22, and water flows in from the third channel 22c.

  Further, the water discharge passage 23 can be communicated with the hot water circulation passage 21 by moving the valve 30 of the temperature adjustment mechanism 16 in accordance with the rotation of the temperature adjustment handle 3. The water discharge passage 23 communicates with the hot water flow passage 21, and when hot water flows in from the hot water flow passage 21, mixes the water and the hot water to generate mixed water.

  The water discharge channel 23 can communicate with the water discharge pipe 6 through a first water discharge port (not shown) formed in the inner case 15 near the center in the left-right direction. Further, the water discharge passage 23 can communicate with the shower hose 7 through a second water discharge port 15g formed in the inner case 15 near the center in the left-right direction. In the water discharge channel 23, a switching valve 41 of the flow rate adjusting mechanism 17 that opens and closes the first water discharge port and the second water discharge port 15g is provided.

  In addition, seal members are provided on the members constituting the hot water flow channel 21, the water flow channel 22, and the water discharge channel 23 so that water or the like does not leak from each of the channels 21 to 23.

  Thus, the internal flow path unit 5 has the water circulation flow path 22, and supplies the water supplied from the water supply pipe 9 to the outside of the internal flow path unit 5, specifically, to the internal flow path unit 5. Without flowing between the faucet body 2, the water can be flowed into the water discharge channel 23.

  The temperature adjustment mechanism 16 includes a valve body 30, a temperature-sensitive spring 31, a bias spring 32, a liner 33, and a spindle.

  The temperature-sensitive spring 31 is housed in a first support case 35 provided at the center in the left-right direction. The temperature sensing spring 31 is provided in the water discharge channel 23. The temperature-sensitive spring 31 is a spring whose spring constant changes according to the temperature, and is made of, for example, a shape memory alloy. The temperature sensing spring 31 biases the valve body 30 to the left.

  The bias spring 32 is housed in a second support case 36 provided on the left side of the first support case 35. The bias spring 32 is provided in the water discharge channel 23. The bias spring 32 is a spring whose spring constant is substantially constant with respect to temperature. The bias spring 32 urges the valve body 30 rightward.

  The valve body 30 is provided between the first support case 35 and the second support case 36. The valve body 30 is supported by the inner case 15 via the separating wall 37 so as to be movable in the left-right direction. The separating wall 37 separates the hot water flow path 21 and the third flow path 22c of the water flow path 22 in the left-right direction. A through hole (not shown) penetrating in the left-right direction is formed in the valve body 30 so that water or mixed water can flow in the left-right direction.

  The valve body 30 moves in the left-right direction in accordance with the urging force of the bias spring 32 and the urging force of the temperature-sensitive spring 31, and adjusts the state of communication between the hot water flow passage 21 and the water discharge passage 23.

  Specifically, when the urging force of the temperature-sensitive spring 31 is larger than the urging force of the bias spring 32, the valve body 30 moves to the left. When the valve element 30 moves to the left and comes into contact with the second support case 36, the communication between the hot water flow path 21 and the water discharge path 23 is cut off. In this case, hot water does not flow into the water discharge channel 23.

  When the biasing force of the bias spring 32 is larger than the biasing force of the temperature-sensitive spring 31, the valve body 30 moves to the right. For example, when the urging force of the bias spring 32 is increased from the state where the valve element 30 is in contact with the second support case 36 and the valve spring 30 is separated from the second support case 36, the hot water flow passage 21 and the water discharge passage 23 communicate. I do. Thereby, hot water flows into the water discharge channel 23.

  When the valve body 30 is separated from the second support case 36, the valve body 30 is held at a position where the biasing force of the bias spring 32 and the biasing force of the temperature-sensitive spring 31 are balanced. As the distance between the valve body 30 and the second support case 36 increases, the amount of hot water flowing into the water discharge channel 23 increases. Further, as the distance between the valve body 30 and the second support case 36 increases, the distance between the valve body 30 and the first support case 35 decreases, and the amount of water flowing into the water discharge passage 23 decreases.

  The liner 33 contacts the end of the bias spring 32 on the opposite side of the valve body 30 and is connected to the temperature adjustment handle 3 via the spindle 34. The spindle 34 is rotatably supported by the second support case 36, and converts the rotational movement of the temperature adjustment handle 3 into the linear movement of the liner 33 in the left-right direction. Therefore, the liner 33 moves in the left-right direction according to the rotation of the temperature adjustment handle 3.

  In the temperature adjustment mechanism 16, the liner 33 moves in the left-right direction according to the rotation position of the temperature adjustment handle 3, and the position of the left end of the bias spring 32 is changed. Therefore, the temperature adjustment mechanism 16 can change the position of the valve body 30 where the biasing force of the bias spring 32 and the biasing force of the temperature-sensitive spring 31 are balanced in accordance with the rotational position of the temperature adjustment handle 3. Therefore, when discharging the mixed water, the temperature adjusting mechanism 16 can set the temperature of the mixed water to a set temperature corresponding to the turning position of the temperature adjusting handle 3.

  When the mixed water is discharged, for example, when the temperature of the hot water changes and the temperature of the mixed water changes, the temperature-sensitive spring 31 expands and contracts according to the temperature of the mixed water, and the valve body 30 moves in the left-right direction, The balance position of the valve body 30 is automatically changed. Thereby, the amount of hot water flowing into the water discharge channel 23 and the amount of water are adjusted, and the temperature of the mixed water is automatically adjusted.

  The flow rate adjusting mechanism 17 includes a rotation shaft 40 and a switching valve 41. The rotation shaft 40 is rotatably supported by the support case 42. One end of the rotating shaft 40 is connected to the flow adjustment handle 4, and the other end is connected to the switching valve 41.

  The switching valve 41 is provided in the water discharge channel 23. The switching valve 41 has a bottomed cylindrical shape, and rotates together with the rotation shaft 40 in accordance with the rotation of the flow adjustment handle 4. The switching valve 41 has a communication port 41a. The switching valve 41 is provided so as to face the first water outlet formed in the inner case 15 and the second water outlet 15g. The switching valve 41 switches the communication state between the communication port 41a, the first water discharge port, and the second water discharge port 15g by rotating in accordance with the rotation of the flow rate adjustment handle 4.

  Specifically, when the flow adjustment handle 4 is at the predetermined water stop position, the communication port 41a does not communicate with the first water outlet and the second water outlet 15g. Therefore, when the flow adjustment handle 4 is at the predetermined water stop position, water or mixed water is not discharged from the water discharge pipe 6 and the hand shower.

  When the flow rate adjustment handle 4 rotates rearward from the water stop position, for example, the communication port 41a communicates with the second water discharge port 15g. As a result, the water or the mixed water flows into the shower hose 7 from the second water outlet 15g, and is discharged from the hand shower.

  When the flow adjustment handle 4 rotates forward from the water stop position, for example, the communication port 41a communicates with the first water discharge port. Thereby, the water or the mixed water flows into the water discharge pipe 6 from the first water discharge port, and is discharged from the water discharge pipe 6.

  The switching valve 41 can change the area where the communication port 41a communicates with the first water outlet or the second water outlet 15g according to the turning position of the flow rate adjustment handle 4. That is, the flow rate adjusting mechanism 17 can adjust the flow rate of water or mixed water discharged from the water discharge pipe 6 or the hand shower in accordance with the rotation position of the flow rate adjustment handle 4.

  Next, the joint 10 and the first connection member 18 will be described with reference to FIG. FIG. 5 is an enlarged view of the vicinity of the first connection member 18 in FIG.

  The joint 10 is formed in a cylindrical shape, and is formed of a metal member. The joint 10 attaches the hot water supply pipe 8 to the faucet main body 2. That is, the joint 10 connects the hot water supply pipe 8 and the faucet main body 2. The first connection member 18 is inserted into the joint 10.

  The joint 10 includes a tubular portion 10a and a nut 10b. The tubular portion 10 a is provided so as to surround the third insertion hole 2 c of the faucet body 2, is welded to the faucet body 2, and is attached to the faucet body 2. The tubular portion 10a protrudes rearward from the faucet main body 2.

  The nut 10b is provided on the outer periphery of the tubular portion 10a, and fastens the tubular portion 10a to the hot water supply pipe 8. In the joint 10, the movement of the nut 10b in the radial direction, that is, the surface direction orthogonal to the front-rear direction is allowed. Thereby, even when the position of hot water supply pipe 8 and cylindrical portion 10a is displaced in a plane direction orthogonal to the front-rear direction, it is possible to fasten cylindrical portion 10a and hot water supply tube 8 with nut 10b.

  The shape of the joint 10 is not limited to a cylindrical shape. For example, in the joint 10, a part of the tubular portion 10a may be formed in a rectangular tubular shape.

  The first connection member 18 is a heat insulating member having a lower thermal conductivity than a metal member such as the faucet main body 2 and the joint 10. The first connection member 18 is made of, for example, a resin. The first connection member 18 connects the hot water supply pipe 8 and the internal flow path unit 5, flows hot water from the rear toward the front, and allows the hot water to flow from the hot water supply pipe 8 into the hot water flow path 21. By configuring the first connection member 18 with a heat insulating member, a rise in the temperature of the joint 10 can be suppressed, and heat transfer to the faucet main body 2 can be suppressed. Therefore, it is possible to suppress a rise in the temperature of the faucet body 2 that is likely to be touched by the user.

  The first connection member 18 is inserted into the internal flow path unit 5 from a direction crossing the left-right direction. Specifically, the first connection member 18 is inserted into the internal flow channel unit 5 from behind. The first connection member 18 forms an insertion member. By inserting the first connection member 18 into the internal flow path unit 5 from a direction intersecting with the left-right direction, fixing the position of the internal flow path unit 5 with respect to the faucet main body 2 when assembling the water discharging device 1. Thus, the assemblability of the water discharging device 1 can be improved. Further, the position of the internal flow path unit 5 with respect to the faucet main body 2 can be fixed using a part of the water discharge device 1.

  The first connection member 18 includes a main body 50, an insertion portion 51, a reduced diameter portion 52, a stopper 53, and a flange 54.

  The main body 50 is formed in a cylindrical shape, and has a check valve 55 provided therein. The check valve 55 allows the flow of hot water from the hot water supply pipe 8 to the hot water flow path 21 and prohibits the flow of hot water from the first flow path 22a to the hot water supply pipe 8.

  The insertion portion 51 is formed in a cylindrical shape, and has a smaller diameter than the main body 50. The insertion portion 51 is inserted into a first insertion hole 15a formed in the inner case 15 of the internal flow path unit 5. A seal member 61 is provided on the outer periphery of the insertion section 51. Between the main body 50 and the insertion portion 51, a reduced diameter portion 52 whose diameter decreases toward the insertion portion 51 is formed.

  The stopper 53 protrudes leftward from the front end of the reduced diameter portion 52. The stopper 53 is sandwiched by the sandwiching member 62 inserted into the faucet main body 2 from the left and the inner case 15 to prevent the first connection member 18 from falling backward.

  The flange 54 protrudes from the rear end of the main body 50 toward the outside in the radial direction of the main body 50, that is, toward the joint 10. The flange 54 is formed all around the main body 50. A seal member 63 is provided between the flange 54 and the hot water supply pipe 8. The surface of the flange 54 on the hot water supply pipe 8 side, that is, the rear surface abuts on the seal member 63, and the surface on the faucet main body 2 side, that is, the front surface abuts on the cylindrical portion 10 a of the joint 10.

  When the hot water supply pipe 8 and the faucet main body 2 are connected by the joint 10, the flange 54 is sandwiched by the hot water supply pipe 8 and the cylindrical portion 10 a of the joint 10 via the seal member 63. Thereby, the first connection member 18 is restricted from moving forward by the cylindrical portion 10a of the joint 10. For this reason, it is possible to suppress the generation of a force that pushes the main body 50 and the insertion portion 51 of the first connection member 18 forward, and suppress the deformation of the main body 50 and the internal flow path unit 5. it can.

  In addition, the allowance for crushing of the seal member 63 can be secured by the flange 54, and leakage of hot water can be prevented.

  As described above, the joint 10 is configured to fasten the tubular portion 10a and the hot water supply pipe 8 even when the position of the tubular portion 10a and the hot water supply pipe 8 is shifted in a plane direction orthogonal to the front-rear direction. Have been. Therefore, the position of the flange 54 and the hot water supply pipe 8 may be shifted in a plane direction orthogonal to the front-rear direction. Even in such a case, the leakage of hot water can be prevented by sandwiching the seal member 63 in the front-rear direction between the flange 54 and the hot water supply pipe 8.

  That is, the seal member 63 is provided between the surface of the flange 54 orthogonal to the front-rear direction and the surface of the front end of the hot water supply pipe 8, and allows displacement in the surface direction orthogonal to the front-rear direction, which is the flow direction of the hot water. This is a face seal to be performed.

  In the joint 10 and the first connecting member 18, between the main body 50 of the first connecting member 18 and the cylindrical portion 10 a of the joint 10, a surface direction orthogonal to the flow direction of the hot water in the first connecting member 18, That is, the first predetermined gap is formed in the radial direction of the main body 50 (the radial direction of the joint 10). Further, a second predetermined gap that is larger than the first predetermined gap in the radial direction of the main body 50 is formed between the flange 54 of the first connection member 18 and the nut 10b of the joint 10. The first predetermined gap and the second predetermined gap are larger than a dimensional tolerance of the first connecting member 18 and the joint 10 and an attachment error generated when the tubular portion 10a of the joint 10 is welded to the faucet main body 2.

  Accordingly, even when a dimensional tolerance of the first connecting member 18 or the joint 10 or an attachment error that occurs when the tubular portion 10a of the joint 10 is welded to the faucet main body 2, the first connecting member is attached to the joint 10. 18, the first connection member 18 can be attached to the internal flow path unit 5.

  In addition, even when an attachment error or the like occurs, the leakage of hot water can be prevented by the seal member 63.

  Further, by providing the first predetermined gap and the second predetermined gap, heat transfer to the faucet main body 2 can be suppressed, and a rise in the temperature of the faucet main body 2 can be suppressed.

  The second connection member 19 has the same configuration as the first connection member 18, and a detailed description is omitted. The stopper 53 of the second connection member 19 protrudes rightward. By making the second connection member 19 have the same configuration as the first connection member 18, the same member can be used as the first connection member 18 and the second connection member 19. Note that the second connection member 19 may be made of, for example, a metal member instead of the heat insulation member.

  In the water discharge device according to the comparative example having no internal flow path unit 5 of the above embodiment, for example, a flow path through which water flows is formed between the faucet main body and the flow path unit. Then, in the water discharging device according to the comparative example, the water flowing between the faucet main body and the flow path unit is caused to flow into the flow path unit.

  However, in the water spouting device according to the comparative example, lead may be eluted from the faucet body or the like into the spouted water.

  In the water discharge device according to the comparative example, a seal member is provided between the water faucet main body and the flow path unit so that water does not leak from a flow path formed between the water faucet main body and the flow path unit. The water spouting device according to the comparative example, in order to improve the insertability of the flow path unit into the faucet body, for example, by inserting the seal member and the flow path unit into the faucet body in a state where the seal member is compressed and frozen. ing.

  However, the water spouting device according to the comparative example requires a device that compresses and freezes the seal member, which increases the cost.

  On the other hand, the water discharge device 1 according to the embodiment can suppress the elution of lead by using the internal flow path unit 5. Further, in the water discharge device 1 according to the embodiment, the internal flow path unit 5 can be easily inserted into the faucet main body 2, and the cost can be reduced.

  Further, the water discharge device 1 according to the embodiment includes a first connection member 18 that is inserted into the internal channel unit 5 from a direction that intersects the left-right direction that is the insertion direction of the internal channel unit 5.
