Japanese Patent Application Laid-Open No. 2002-228040

In the hot and cold water mixing faucet described above, since the outer shell member is tubular and has a curved surface, the discharge pipe cannot be directly brazed. Therefore, for example, the water discharge pipe is attached to the outer shell member by brazing the water discharge pipe to the outer shell member in which the connecting portion is formed by burring. If burring is performed and the discharge pipe is brazed to the outer shell member, the cost for manufacturing the hot and cold water mixing faucet increases.

On the other hand, a method of directly connecting the discharge pipe to the channel unit is conceivable. However, in a hot water mixing faucet in which a discharge pipe is connected to a flow channel unit, for example, when an external force is applied to the discharge pipe, the external force may be transmitted to the flow channel unit and damage the flow channel unit.

An object of one aspect of the embodiments is to provide a hot and cold water mixing faucet that does not transmit an external force applied to the discharge pipe to the internal flow path unit and suppresses damage to the internal flow path unit.

A hot and cold water mixing faucet according to an aspect of an embodiment includes an internal channel unit in which an internal channel is formed, the internal channel unit is inserted, and the cross section orthogonal to the insertion direction of the internal channel unit is circular. An outer shell member having a certain inner peripheral wall, a water discharge pipe for discharging mixed water of cold and hot water or the water to the outside, and an insertion hole formed in the inner peripheral wall to be inserted into the inner flow path unit and the discharge a connection member for connecting the water pipe, wherein the connection member comes into contact with the outer shell member when an external force is applied to the water discharge pipe.

When an external force is applied to the discharge pipe, the connection member that connects the internal flow channel unit and the discharge pipe contacts the outer shell member, so that the external force applied to the discharge pipe is not transmitted to the internal flow channel unit, and the internal flow Damage to the road unit can be suppressed.

Further, the hot and cold water mixing faucet further includes an insertion member inserted into the internal channel unit in a direction crossing the insertion direction, and the gap formed between the connection member and the outer shell member is It is characterized by being smaller than a gap formed between the insertion member and the outer shell member.

By making the gap formed between the connection member and the shell member smaller than the gap formed between the insertion member and the shell member, movement of the connection member is suppressed when an external force is applied to the discharge pipe. The external force can be received by the outer shell member by regulating it. Therefore, external force is not transmitted to the internal flow path unit, and damage to the internal flow path unit can be suppressed.

Moreover, the sealing member is provided between the inner peripheral wall of the connection member and the internal flow path unit facing the inner peripheral wall of the connection member.

By providing a sealing member between the inner peripheral wall of the connection member and the internal flow path unit, even when the connection state between the connection member and the internal flow path unit is loosened, the sealing performance can be maintained and water, etc. leakage can be suppressed.

Further, the internal flow path unit is characterized in that the flow path is completed inside the internal flow path unit, and no seal is interposed between the internal flow path unit and the outer shell member.

To improve workability because the flow path is completed inside the internal flow path unit and the internal flow path unit can be inserted into the outer shell member without using a seal between the outer shell member and the internal flow path unit. can be done. In addition, when inserting the internal flow path unit into the outer shell member, even if the position of the internal flow path unit with respect to the outer shell member is shifted in the circumferential direction, the position can be easily aligned, and workability can be improved. .

Further, the connection member is characterized by having a chamfered portion at the end on the internal flow path unit side.

By providing the connecting member with the chamfered portion, the connecting member can be easily inserted into the outer shell member. Also, contact between the connection member and the internal flow path unit can be suppressed, and damage to the internal flow path unit can be suppressed.

According to one aspect of the embodiment, damage to the internal channel unit can be suppressed.

The temperature control handle 3 switches the type of fluid spouted from the spout pipe 6 or the hand shower to water or mixed water depending on the rotational position. Specifically, the temperature adjustment handle 3 switches whether hot water is mixed with cold water. Further, the temperature control handle 3 sets the temperature of the mixed water according to the rotation position when the mixed water is discharged from the discharge pipe 6 or the hand shower.

The flow rate adjusting handle 4 is rotatably attached to the faucet body 2 . The flow rate adjusting handle 4 switches the water or mixed water spouting destination to the spouting pipe 6 or the hand shower according to the rotational position. Also, the flow rate adjusting handle 4 adjusts the flow rate of water or mixed water spouted from the spouting pipe 6 or the hand shower in accordance with the rotational position.

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

The internal channel unit 5 is a unit that allows the water supplied from the water supply pipe 9 to flow between the faucet main body 2 and the internal channel unit 5 without allowing it to flow. That is, the internal channel unit 5 is a unit in which the channel is completed. Therefore, no seal is interposed between the internal channel unit 5 and the faucet body 2 . The internal channel unit 5 includes an internal case 15 , a temperature adjustment mechanism 16 and a flow rate adjustment mechanism 17 .

The inner case 15 accommodates the temperature adjustment mechanism 16 and the flow rate adjustment mechanism 17 . The inner case 15 is formed in a substantially cylindrical shape to match the inner peripheral wall 2 a of the faucet body 2 . The inner case 15 is made of a resin member.

A first insertion hole 15a is formed in the inner case 15 on the left rear side. A first connection member 18 for supplying 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 on the rear right side. A second connection member 19 for supplying water from the water supply pipe 9 is inserted into the second insertion hole 15b.

The internal case 15 is formed with an internal flow path 20 through which water, hot water, or mixed water flows. The internal flow path 20 is a flow path through which water or mixed water is discharged from the discharge pipe 6 or the hand shower without allowing water to flow between the internal flow path unit 5 and the faucet main body 2 . The internal channel 20 is composed of a hot water flow channel 21 , a water flow channel 22 and a water discharge channel 23 .

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

Water supplied from the water supply pipe 9 flows through the water flow passage 22 through the second connection member 19 . The water flow channel 22 is composed of a first channel 22a, a second channel 22b, and a third channel 22c.

The first flow path 22 a is formed by the inner case 15 and the support case 42 of the flow rate adjustment 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 recess 15c formed near the front center of the inner case 15 and a lid 15d covering the recess 15c. A sealing member 60 is provided between the lid portion 15d and the recessed portion 15c.

The lid portion 15 d is pressed by the inner peripheral wall 2 a of the faucet body 2 when the internal flow path unit 5 is inserted into the faucet 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 forward movement of the lid portion 15d is restricted by the inner peripheral wall 2a. Therefore, water leakage from the second flow path 22b can be prevented.

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. Also, the second flow path 22b communicates with the third flow path 22c via the second flow hole 15f formed on the left side, 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 body 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 with the isolation wall 37 therebetween in the left-right direction.

The water discharge channel 23 is formed by a first support case 35, a second support case 36, etc. of the temperature control mechanism 16 radially inward of the inner case 15 relative to the hot water circulation channel 21 and the water circulation 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.

Also, the water discharge channel 23 can communicate with the hot water circulation channel 21 by moving the valve body 30 of the temperature control mechanism 16 according to the rotation of the temperature control handle 3 . The water discharge channel 23 communicates with the hot water circulation channel 21, and when hot water flows in from the hot water circulation channel 21, the water and the hot water are mixed to generate mixed water.

The water discharge channel 23 can communicate with the water discharge pipe 6 via a first water discharge port 15h (see FIG. 6) formed in the inner case 15 near the center in the left-right direction. Also, the water discharge channel 23 can communicate with the shower hose 7 via a second water discharge port 15g formed in the inner case 15 near the center in the left-right direction. The water discharge channel 23 is provided with a switching valve 41 of the flow rate adjustment mechanism 17 that opens and closes the first water discharge port 15h and the second water discharge port 15g.

In addition, sealing members are provided in the members forming the hot water flow path 21, the water flow path 22, and the water discharge flow path 23 so that water and the like do not leak from the flow paths 21-23.

As described above, the internal flow channel unit 5 has the water flow channel 22, and the water supplied from the water supply pipe 9 flows outside the internal flow channel unit 5, specifically, through the internal flow channel unit 5. The water can flow through the water discharge channel 23 without flowing between the faucet main body 2. - 特許庁

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 34 .

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

The bias spring 32 is housed in a second support case 36 provided to the left of the first support case 35 . A bias spring 32 is provided in the water discharge channel 23 . The bias spring 32 is a spring with a substantially constant spring constant with respect to temperature. A 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 isolation wall 37 so as to be movable in the left-right direction. The isolation wall 37 isolates the hot water flow path 21 from 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, and water and mixed water can be circulated in the left-right direction.

The valve body 30 moves in the lateral direction according to the biasing force of the bias spring 32 and the biasing force of the temperature sensing spring 31 to adjust the state of communication between the hot water flow path 21 and the water discharge path 23 .

Specifically, the valve body 30 moves leftward when the biasing force of the temperature-sensitive spring 31 is greater than the biasing force of the bias spring 32 . When the valve body 30 moves leftward and comes into contact with the second support case 36, 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 .

Further, when the biasing force of the bias spring 32 is larger than the biasing force of the temperature sensing spring 31, the valve body 30 moves rightward. For example, when the urging force of the bias spring 32 increases from a state in which the valve body 30 abuts against the second support case 36 and is separated from the second support case 36, the hot water flow channel 21 and the water discharge channel 23 communicate with each other. do. As a result, hot water flows into the water discharge channel 23 .

When the valve body 30 is separated from the second support case 36, the biasing force of the bias spring 32 and the biasing force of the temperature sensing spring 31 are held in a balanced position. 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 passage 23 increases. Also, the longer the distance between the valve body 30 and the second support case 36, the shorter the distance between the valve body 30 and the first support case 35, and the less water flows into the water discharge passage 23.

A liner 33 abuts the end of the bias spring 32 opposite the valve body 30 and is connected to the temperature control handle 3 via a spindle 34 . The spindle 34 is rotatably supported by the second support case 36 and converts the rotational movement of the temperature control handle 3 into the linear movement of the liner 33 in the horizontal direction. Therefore, the liner 33 moves laterally in accordance with the rotation of the temperature adjustment handle 3 .

In the temperature adjustment mechanism 16 , the liner 33 moves in the horizontal direction in accordance with 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 at which the biasing force of the bias spring 32 and the biasing force of the temperature sensing spring 31 are balanced according to the rotation position of the temperature adjustment handle 3 . Therefore, the temperature adjustment mechanism 16 can adjust the temperature of the mixed water to the set temperature according to the rotation position of the temperature adjustment handle 3 when the mixed water is spouted.

Further, 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 sensing spring 31 expands and contracts according to the temperature of the mixed water, the valve body 30 moves in the left and right direction, The balanced position of the valve body 30 is automatically changed. As a result, the amount of hot water and the amount of water flowing into the water discharge passage 23 are adjusted, and the temperature of the mixed water is automatically adjusted.

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

The switching valve 41 is provided in the water discharge flow path 23 . The switching valve 41 has a cylindrical shape with a bottom, and rotates together with the rotation shaft 40 in accordance with the rotation of the flow rate adjusting handle 4 . A communication port 41 a is formed in the switching valve 41 . The switching valve 41 is provided so as to face the first water outlet 15h and the second water outlet 15g formed in the inner case 15 . The switching valve 41 rotates in accordance with the rotation of the flow rate adjusting handle 4 to switch the state of communication between the communication port 41a, the first water outlet 15h, and the second water outlet 15g.

Specifically, when the flow rate adjusting handle 4 is at a predetermined water stop position, the communication port 41a does not communicate with the first water outlet 15h and the second water outlet 15g. Therefore, when the flow rate adjusting handle 4 is at a 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 adjusting handle 4 rotates backward from the water stop position, for example, the communication port 41a communicates with the second water outlet 15g. As a result, water or mixed water flows into the shower hose 7 from the second spout 15g and is spouted from the hand shower.

Further, when the flow rate adjusting handle 4 rotates forward from the water stop position, for example, the communication port 41a communicates with the first water discharge port 15h. As a result, water or mixed water flows into the water discharge pipe 6 from the first water discharge port 15 h 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 15h or the second water outlet 15g according to the rotational position of the flow rate adjusting handle 4. That is, the flow rate adjusting mechanism 17 can adjust the flow rate of water or mixed water spouted from the spouting pipe 6 or the hand shower in accordance with the rotational position of the flow rate adjusting handle 4 .

A chamfered portion 51 a is formed at the upper end of the body portion 51 . By forming the chamfered portion 51a, the upper end of the main body portion 51 can be easily inserted into the first insertion hole 2e. Further, by forming the chamfered portion 51a, for example, when the external force of the water discharge pipe 6 is applied, the upper end of the main body portion 51 of the third connection member 50 can be brought into contact with the inner case 15 of the internal flow path unit 5. can be suppressed, and damage to the internal flow path unit 5 can be suppressed.

That is, the third connecting member 50 is watertightly connected to the internal flow path unit 5 by the sealing member 61 .

The insertion portion 6 a of the discharge pipe 6 is inserted into the body portion 51 . The body portion 51 is connected to the insertion portion 6a by tightening the lower end side with a nut 62 .

The mounting portion 52 protrudes radially inward of the body portion 51 from the inner peripheral wall 51 b of the body portion 51 . The attachment portion 52 is sandwiched between the head portion 63 a of the screw 63 and the internal flow path unit 5 by attaching the screw 63 to the internal flow path unit 5 . Thereby, the third connection member 50 is attached to the internal channel unit 5 .

FIG. 7 is an enlarged schematic diagram of the upper end side of the third connecting member 50 of FIG. The predetermined gap d is smaller than the gap formed between other members capable of restricting movement of the internal flow path unit 5 when an external force is applied to the water discharge pipe 6 . Other members are insertion members inserted into the internal channel unit 5 from a direction intersecting the insertion direction, such as the first connection member 18 and the second connection member 19 . That is, the predetermined gap d is smaller than the gap formed between the insert member and the faucet body 2 . The predetermined gap d is smaller than, for example, the gap formed between the second connection member 19 and the joint 11 shown in FIG. 8 or the gap formed between the second connection member 19 and the faucet main body 2. . FIG. 8 is a cross-sectional view taken along line VIII-VIII of FIG.
