Description

The present invention relates to a faucet.

Conventionally, faucets used in kitchens, washrooms, etc. have been disclosed (see, for example, Patent Document 1). The faucet disclosed in Patent Document 1 includes a spout forming a spout and a push button attached to the tip of the spout. By operating the push button, you can switch between straight water discharge and shower water discharge.

Inside the spout, a spring is provided to urge the push button forward. When the user presses the push button, the push button is moved from the front position to the rear position against the urging force of the spring and is held in the rear position. At this time, shower water is discharged. When the user further presses the push button, the urging force of the spring returns the push button from the rear position to the front position and holds it in the front position. At this time, straight water discharge is performed.

JP-A-2005-16032

In the configuration of Patent Document 1, since the push button is returned by using the urging force of the spring, if the urging force of the spring is insufficient, the push button does not return and may not operate normally. In order to prevent this, it was necessary to take measures such as increasing the urging force of the spring. As described above, it can be said that there is room for improvement in operating the push button normally in the mechanism for operating the push button by utilizing the urging force of the spring.

Therefore, an object of the present invention is to provide a faucet capable of operating the push button more normally in a mechanism for operating the push button by utilizing the urging force of the spring in order to solve the above problem. It is in.

In order to achieve the above object, the faucet of the present invention has an upstream side flow path, a first downstream side flow path and a second downstream side flow path branching downstream of the upstream side flow path, and the upstream side flow path. A spout extending in the axial direction and a spout that connects the side flow path and the first and second downstream side flow paths are formed inside, and the first downstream side flow path is provided in the connection flow path. A first position that blocks the entrance of the road to communicate the upstream flow path and the second downstream flow path, and blocks the entrance of the second downstream flow path to connect the upstream flow path and the upstream flow path. A switching valve that can move between a second position that communicates with the first downstream flow path, and a mechanism that holds the switching valve at each of the first position and the second position. The switching valve is moved between the first position and the second position by a position holding mechanism having an urging member for urging the switching valve toward the second position and a user operation. When the hydraulic resistance received when moving from the first position to the second position moves from the second position to the first position, the switching valve includes an operation unit for causing the operation. It is provided at a position that is smaller than the hydraulic resistance received by the water pressure.

According to the faucet of the present invention, the push button can be operated more normally.

Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings. The present invention is not limited to this embodiment.

(Embodiment)
1 and 2 are schematic perspective views of the faucet 2 in the embodiment. FIG. 1 shows a state in which the spout 6 of the faucet 2 is housed, and FIG. 2 shows a state in which the spout 6 is pulled out forward. 3 and 4 are diagrams showing a schematic configuration of the spout 6. FIG. 3 is a side view of the spout 6, and FIG. 4 is a bottom view of the spout 6.

The faucet 2 shown in FIGS. 1 and 2 is a single lever type faucet device used in kitchens, washrooms, and the like. The faucet 2 includes a main body 4 that is erected on an installation table (not shown), a lever 5, a spout 6, a push button 10, and a water discharge unit 12. The water spouting unit 12 is a member forming a plurality of watering holes for spouting hot water, and is also referred to as a "watering plate" or a "shower face".

The main body 4 is a member that integrally supports the lever 5 and the spout 6. A push button 10 and a water discharge portion 12 are attached to the tip portion of the spout 6. The spout 6 is also referred to as a "water pipe" or a "shower head". The spout 6 extends in the axial direction C from the base end side connected to the main body 4 toward the tip end side to which the push button 10 is attached.

By operating the lever 5, the user can switch between spouting and stopping water from the spouting unit 12, and can adjust the spouting temperature and the amount of spouting water. Further, when the user pushes the push button 10, the water discharge from the water discharge unit 12 can be switched between the shower water discharge and the straight water discharge. The push button 10 is an example of an operation unit for switching water discharge by a user operation. The detailed mechanism for switching the water discharge will be described later.

The internal configuration of the spout 6 shown in FIGS. 3 and 4 will be described with reference to FIGS. 5 and 6. 5 is a sectional view taken along the line AA of FIG. 3, and FIG. 6 is a sectional view taken along the line BB of FIG.

As shown in FIGS. 5 and 6, a flow path forming portion 14 is provided inside the spout 6. The flow path forming unit 14 is a member that forms a flow path for hot water to be discharged from the water discharge unit 12 described above. Hot water is supplied to the flow path forming portion 14 from a hot water supply source (not shown) on the upstream side via another flow path forming portion 38.

As shown in FIG. 6, the flow path forming portion 14 includes a pipe portion 15. The pipe portion 15 is a tubular member that internally forms a first downstream flow path 16 and a second downstream flow path 18. The first downstream flow path 16 is a flow path for straight water discharge, and the second downstream flow path 18 is a flow path for shower water discharge. Both the first downstream flow path 16 and the second downstream side flow path 18 are connected to the water discharge hole of the water discharge unit 12.

The flow path forming unit 14 further includes a flow path switching unit 20 for selectively switching between the first downstream side flow path 16 and the second downstream side flow path 18. The flow path switching unit 20 includes a switching valve 22 (FIG. 6), a valve holding unit 24, a cam mechanism 26 (FIG. 5), a link 28, and a position holding mechanism 30.

The switching valve 22 is a valve body that selectively closes either one of the first downstream flow path 16 and the second downstream side flow path 18. The switching valve 22 of the present embodiment is a valve ball provided so that the spout 6 can rotate around the axial direction C. The switching valve 22 is between a position where the inlet 16A of the first downstream flow path 16 is closed (first position) and a position where the inlet 18A of the second downstream flow path 18 is closed (second position). It is rotatable. FIG. 6 shows a state in which the switching valve 22 is in the first position. In this state, shower water is discharged from the water discharge unit 12 through the second downstream flow path 18.

The valve holding portion 24 is a member that holds the switching valve 22. The valve holding portion 24 is connected to the cam mechanism 26 (FIG. 5). The cam mechanism 26 is a member that converts a linear motion in the axial direction C due to the pushing of the push button 10 into a rotary motion centered on the axial direction C of the spout 6. The cam mechanism 26 is connected to the second link 28b of the link 28.

The link 28 is a member that connects the cam mechanism 26 described above and the position holding mechanism 30 described later to each other. The link 28 is attached to the inside of the push button 10 and moves along the axial direction C of the spout 6 in response to the push of the push button 10. The link 28 includes a first link 28a and a second link 28b as two branching branches. The first link 28a is connected to the position holding mechanism 30, and the second link 28b is connected to the cam mechanism 26.

The position holding mechanism 30 is a mechanism that maintains two states, a pushed state and a non-pushed state, of the push button 10. That is, the position holding mechanism 30 has a function of holding the switching valve 22 at each of the first position and the second position. The position holding mechanism may be referred to as an "alternate mechanism". The first position of the switching valve 22 shown in FIGS. 5 and 6 corresponds to the pushed state of the push button 10, and the second position of the switching valve 22 corresponds to the non-pushed state of the push button 10.

As shown in FIG. 5, the position holding mechanism 30 includes a knock type mechanism including springs 32A, 32B and the like. The springs 32A and 32B of the present embodiment are an example of an urging member that functions to urge the switching valve 22 toward the second position. At the first position shown in FIG. 6, the springs 32A and 32B urge the switching valve 22 toward the second position, but the position holding mechanism 30 maintains the switching valve 22 at the first position.

In the above-described configuration, when the switching valve 22 is in the second position in the non-pushed state, it moves to the first position against the urging force of the springs 32A and 32B by the push operation of the push button 10. At the first position, shower water is discharged from the water discharge unit 12. When the push button 10 is further pushed from this state, the state maintenance of the switching valve 22 by the position holding mechanism 30 is released. As a result, the switching valve 22 moves to the second position by utilizing the urging force of the springs 32A and 32B. At the second position, straight water discharge is performed. By such a push operation of the push button 10, the position of the switching valve 22 can be switched between the first position and the second position to switch between shower water discharge and straight water discharge.

The configuration around the switching valve 22 described above will be described with reference to FIG. 7. FIG. 7 is an enlarged vertical cross-sectional view of the periphery of the switching valve 22.

As shown in FIG. 7, in addition to the first downstream flow path 16 and the second downstream side flow path 18, an upstream side flow path 34 and a connection flow path 36 are provided inside the spout 6. ing.

The upstream side flow path 34 is the most upstream flow path in the flow path in the spout 6. The upstream side flow path 34 is provided on the upstream side of the connection flow path 36 and is connected to the connection flow path 36. The upstream side flow path 34 is formed by another flow path forming portion 38. Hot water whose temperature and flow rate are adjusted is supplied from the main body 4 (FIGS. 1 and 2) described above to the upstream flow path 34.

The connection flow path 36 is a flow path that connects the upstream side flow path 34 with the first downstream side flow path 16 and the second downstream side flow path 18. The connection flow path 36 is provided between the upstream side flow path 34 and the first downstream side flow path 16 and the second downstream side flow path 18. As shown in FIG. 7, a switching valve 22 and a valve holding portion 24 are arranged in the connecting flow path 36. FIG. 7 shows a state in which the switching valve 22 is in the second position of blocking the second downstream flow path 18.

As shown in FIG. 7, an orifice 39 is formed at the boundary between the upstream side flow path 34 and the connection flow path 36. The orifice 39 is formed by an orifice plate 40 projecting inward from the inner peripheral wall of the flow path forming portion 38. The orifice 39 constitutes the outlet 34A of the upstream flow path 34.

In a state where hot water is flowing in the spout 6, the water flow W from the upstream side flow path 34 hits the side surface 24A of the valve holding portion 24. A hydraulic resistance R is applied to the switching valve 22 held by the valve holding portion 24 when moving between the first position and the second position.

The hydraulic resistance R received when the switching valve 22 is in each of the first position and the second position will be described with reference to FIGS. 8A and 8B. FIG. 8A shows a state in which the switching valve 22 is in the first position, and FIG. 8B shows a state in which the switching valve 22 is in the second position.

In this embodiment, the hydraulic resistance R1 received at the first position shown in FIG. 8A is designed to be smaller than the hydraulic resistance R2 received at the second position shown in FIG. 8B. Specifically, it is realized by setting the positional relationship of the plurality of flow paths 16, 18 and 34, and the positions of the switching valve 22 and the valve holding portion 24 to predetermined positions in advance. With such a setting, the water pressure resistance (≈R1) received when the switching valve 22 moves from the first position to the second position is changed to the water pressure resistance received when moving from the second position to the first position. It is smaller than (≈R2). As described above, when the switching valve 22 moves from the first position to the second position, the switching valve 22 moves by utilizing the urging force of the springs 32A and 32B of the position holding mechanism 30. At this time, since the hydraulic resistance (≈R1) received by the switching valve 22 is set to be small, the switching valve 22 can be moved and returned even when the urging forces of the springs 32A and 32B are small. As a result, the push button 10 can be operated normally.

On the other hand, when the switching valve 22 moves from the second position to the first position, the push button 10 is pushed against the urging force of the springs 32A and 32B, so that the switching valve 22 moves. The hydraulic resistance (≈R2) at this time is set large, but unlike the case where the urging force of the springs 32A and 32B is used, the switching valve 22 can be reliably moved by increasing the pushing force by the user. ..

To calculate and measure the hydraulic resistances R1 and R2 at the first position and the second position, for example, the pressing pressure (maximum value) of the push button 10 required to move the switching valve 22 is measured with a force gauge. It may be calculated indirectly by reading the measured values as hydraulic resistances R1 and R2. As the force gauge, a general commercially available force gauge may be used. Alternatively, a pressure gauge may be provided in the connection flow path 36 to directly calculate the hydraulic resistances R1 and R2.

In order to realize the relationship of hydraulic resistance as described above, the faucet 2 of the present embodiment is devised in the positional relationship as shown in FIG. FIG. 9 is a diagram showing the inside of the spout 6 when viewed from the flow path direction (axial direction C of the spout 6) of the upstream side flow path 34.

As shown in FIG. 9, the outlet 34A (orifice 39) of the upstream side flow path 34 has a circular cross section. A center 34C exists at the outlet 34A of the upstream flow path 34. In front of the outlet 34A of the upstream flow path 34 (on the tip side of the spout 6), the inlet 16A of the first downstream flow path 16 and the inlet 18A of the second downstream flow path 18 via the connection flow path 36. Is located. Both the inlet 16A and the inlet 18A have a circular cross section. The entrance 16A has a center 16C, and the entrance 18A has a center 18C.

As shown in FIG. 9, the center 16C of the inlet 16A is located above the center 34C of the exit 34A. On the other hand, the center 18C of the inlet 18A is located below the center 34C of the exit 34A.

The distance (cross-sectional distance, height distance) D1 from the center 16C to the center 34C is set longer than the distance (cross-sectional distance, height distance) D2 from the center 34C to the center 18C. According to such a setting, in the vertical cross section shown in FIG. 9, the inlet 16A of the first downstream flow path 16 is the outlet 16A of the second downstream flow path 18 with respect to the outlet 34A of the upstream side flow path 34. It is located farther than the entrance 18A. As a result, at the first position where the switching valve 22 closes the inlet 16A of the first downstream flow path 16, the area where the water flow W directly hits the side surface 24A of the valve holding portion 24 is larger than that at the second position. It becomes smaller. Therefore, the hydraulic resistance R received by the switching valve 22 is also reduced. By setting the positions of the centers 16C, 18C, and 34C in this way, it is easy to configure the hydraulic resistance R1 received at the first position shown in FIG. 8A to be smaller than the hydraulic resistance R2 received at the second position shown in FIG. 8B. Can be realized.

Further, since the first downstream flow path 16 is located above the second downstream flow path 18, gravity occurs when the switching valve 22 moves from the first position to the second position. Can receive the driving force of. Since the propulsive force of gravity can be used in addition to the urging force of the springs 32A and 32B, the switching valve 22 can be reliably moved even when the urging force of the springs 32A and 32B is even smaller. As a result, the push button 10 can be operated normally.

Further, since the first downstream flow path 16 and the second downstream flow path 18 are arranged side by side in the vertical direction, the dimension of the spout 6 in the width direction X can be shortened. As a result, the spout 6 can be made thinner, and the design of the faucet 2 can be improved.

As described above, the faucet 2 of the present embodiment includes a spout 6, a push button 10, a switching valve 22, and a position holding mechanism 30. The spout 6 internally forms an upstream side flow path 34, a first downstream side flow path 16, a second downstream side flow path 18, and a connection flow path 36. The switching valve 22 has a first position in which the inlet 16A of the first downstream flow path 16 is closed to communicate the upstream side flow path 34 and the second downstream side flow path 18, and a second downstream side flow path. It is movable between a second position that blocks the inlet 18A of 18 and communicates the upstream flow path 34 and the first downstream flow path 16. The push button 10 is an operation unit that moves the switching valve 22 between the first position and the second position by a user's push operation. The position holding mechanism 30 is a mechanism for holding the switching valve 22 at the first position and the second position, respectively, and has springs 32A and 32B for urging the switching valve 22 toward the second position. Have. The water pressure resistance (≈R1) received by the switching valve 22 when moving from the first position to the second position is higher than the water pressure resistance (≈R2) received when moving from the second position to the first position. It is provided at a position smaller than that.

According to such a configuration, when the switching valve 22 is moved from the second position to the first position, the push button 10 is pushed against the spring force, while the push button 10 is pushed from the first position to the second position. When returning to, the switching valve 22 returns using the urging force of the springs 32A and 32B. The hydraulic resistance (≈R1) received when the switching valve 22 returns using the urging force of the springs 32A and 32B is set to be smaller than the hydraulic resistance (≈R2) when the switching valve 22 moves in the opposite direction. Therefore, if the urging force is set so as to exceed the hydraulic resistance, the switching valve 22 can be reliably returned. With such a configuration, the switching valve 22 can be reliably returned even if the spring force is set small, and the push button 10 is normally operated in the mechanism for operating the push button 10 by utilizing the urging force of the springs 32A and 32B. Can be operated.

Further, according to the faucet 2 of the present embodiment, in the cross section of the upstream side flow path 34 when viewed from the flow path direction, the center 16C of the inlet 16A of the first downstream side flow path 16 is the second downstream side flow path. It is located farther from the center 18C of the inlet 18A of 18 and the center 34C of the outlet 34A of the upstream flow path 34.

According to such a configuration, the inlet 16A of the first downstream flow path 16 is farther from the outlet 34A of the upstream side flow path 34 than the inlet 18A of the second downstream side flow path 18, and the inlet 16A is used. The hydraulic resistance R1 received by the switching valve 22 at the first position to close is also reduced. As a result, the water pressure resistance (≈R1) received when the switching valve 22 moves from the first position to the second position becomes the water pressure resistance (≈R1) received when moving from the second position to the first position. A configuration smaller than ≈R2) can be easily realized.

Further, according to the faucet 2 of the present embodiment, in the cross section of the upstream side flow path 34 when viewed from the flow path direction, the center 16C of the inlet 16A of the first downstream side flow path 16 is the second downstream side flow. It is above the center 18C of the entrance 18A of the road 18.

According to such a configuration, when the switching valve 22 moves from the first position blocking the first downstream flow path 16 to the second position blocking the second downstream flow path 18, the spring In addition to the urging force, it can receive the propulsive force by gravity. As a result, the switching valve 22 can be reliably moved even if the urging force of the spring is further reduced, and the push button 10 can be operated normally.

Further, according to the faucet 2 of the present embodiment, the first downstream flow path 16 and the second downstream flow path 18 are arranged side by side in the vertical direction.

By arranging the two downstream flow paths 16 and 18 side by side in this way, the lateral dimension of the spout 6 can be reduced. Thereby, the design of the faucet 2 can be improved.

Further, according to the faucet 2 of the present embodiment, the switching valve 22 is provided at a position where the water pressure resistance R1 received at the first position is smaller than the water pressure resistance R2 received at the second position.

According to such a configuration, the hydraulic resistance (≈R1) received when moving from the first position to the second position is the hydraulic resistance (≈R1) received when moving from the second position to the first position. A configuration smaller than ≈R2) can be easily realized.

The present invention is not limited to the above embodiment, and can be implemented in various other aspects. For example, in the embodiment, the case where the faucet 2 is a single-lever type faucet device has been described, but the present invention is not limited to such a case, and a faucet device other than the single-lever type may be used.

Further, in the embodiment, the center 16C of the inlet 16A of the first downstream flow path 16 is set to the center 34C of the outlet 34A of the upstream side flow path 34 from the center 18C of the inlet 18A of the second downstream flow path 18. On the other hand, the case where the device is provided at a distant position has been described, but the case is not limited to such a case. The distance D1 from the center 16C to the center 34C and the distance D2 from the center 34C to the center 18C may be set to be the same. Even in such a case, the side surface of the valve holding portion 24 that maintains the vertical relationship between the inlet 16A of the first downstream flow path 16 and the inlet 18B of the second downstream flow path 18 or receives the water flow W. The magnitude relationship of the hydraulic resistance shown in FIGS. 8A and 8B may be realized by changing the shape of 24A or the like.

Further, in the embodiment, the case where two springs 32A and 32B are provided as the springs 32A and 32B of the position holding mechanism 30 has been described, but the number and location of the springs are not limited to this. Any spring may be used as long as it has a function of urging the switching valve 22 toward either the first position or the second position.

Further, in the embodiment, the springs 32A and 32B are exemplified as the urging members for urging the switching valve 22, but the present invention is not limited to such a case. Any form of urging member other than the spring may be used as long as it has a function of urging the switching valve 22.

Further, in the embodiment, the push button 10 is illustrated as an example of an operation unit in which the user switches the position of the switching valve 22, but the present invention is not limited to such a case. The position of the switching valve 22 may be switched by an operation other than the push operation (for example, twisting or rotation), or an operation unit of any form may be used.

Further, in the embodiment, the case where the water flow W passed through the upstream side flow path 34 is directly applied to the side surface portion 24A of the valve holding portion 24 has been described, but the case is not limited to such a case. For example, the flow rate adjusting plate 52 may be provided as in the modified example shown in FIG. The flow rate adjusting plate 52 shown in FIG. 10 is a disk-shaped member in which a plurality of through holes 54 are formed in the thickness direction as shown in FIG. In the example shown in FIG. 10, the flow rate adjusting plate 52 is provided at a position adjacent to the orifice plate 40. The flow rate adjusting plate 52 is fixed by pressing it with a hose (not shown) while being inserted at the position shown in FIG. 10, but the flow rate adjusting plate 52 is not limited to the case where it is separate from the flow path forming portion 38. It may be integrally formed with the road forming portion 38. According to such a configuration, the flow rate of the water flow W passed through the upstream side flow path 34 is reduced when passing through the flow rate adjusting plate 52. As a result, it is possible to prevent the hydraulic resistance R2 applied to the side surface portion 24A of the valve holding portion 24 from becoming excessively large. Therefore, the position of the switching valve 22 can be easily switched by the push operation of the push button 10.

The flow rate adjusting plate 52 is not limited to the configuration shown in FIGS. 10 and 11, and any configuration may be adopted as long as the flow rate of the water flow W can be reduced. For example, the flow rate adjusting plates 62 and 72 as shown in FIGS. 12 and 13 may be adopted. The flow rate adjusting plate 62 shown in FIG. 12 is a disk-shaped member in which a plurality of through holes 64 are penetrated in the thickness direction, and the flow rate adjusting plate 72 shown in FIG. 13 also has a plurality of through holes 74 in the thickness direction. It is a disk-shaped member that penetrates through. According to such a configuration, the flow rate of the water flow W passed through the upstream side flow path 34 can be reduced when passing through the flow rate adjusting plate 62 or the flow rate adjusting plate 72. As a result, it is possible to prevent the hydraulic resistance R2 from becoming excessively large, and the position of the switching valve 22 can be easily switched by the push operation of the push button 10.

By appropriately combining the various forms described above, the effects of each can be achieved.

Although the present invention has been fully described in connection with preferred embodiments with reference to the accompanying drawings, various modifications and modifications are obvious to those skilled in the art. It should be understood that such modifications and modifications are included therein, as long as they do not deviate from the scope of the invention according to the appended claims. In addition, changes in the combination and order of elements in the embodiments can be realized without departing from the scope and ideas of the present invention.
