In FIGS. 3A to 4B, etc., for convenience, the x-axis, y-axis, and z-axis that are perpendicular to each other are displayed. In addition, each axis is set for the convenience of explanation, and it is not a specific designation of the direction of the outlet pipe 30.

The faucet 40 according to Embodiment 1 of the present invention is provided with a water outlet pipe 30 that can be pulled out. As shown in FIGS. 1 and 2, the outlet pipe 30 is arranged at the front end of the body 34 of the faucet 40. In addition, the water outlet pipe 30 includes a hose connection member 4 to which the hose 36 is connected, a water passage component 38, and a cover 1 covering the hose connection member 4 and the water passage component 38. The water passage constituent member 38 includes two water passages A and B connected to the water outlet 10 and a communication portion 3 from the main water passage C side of the hose 36 to the branch position leading to the two water passages A and B. The water passage constituent member 38 is connected to the hose connection member 4. In addition, the water passage constitution member 38 is attached to the longitudinal direction of the water outlet pipe 30 and has a communication portion 3 on the side of the hose connection member 4 opposite to the water outlet portion 10. In addition, this faucet 40 is only an example and is not limited to the configuration shown in FIGS. 1 and 2.

According to this faucet 40, the hose connection member 4 is separated from the water path component 38 including the two water paths A and B and the water path component 38 from the side of the main water path C of the hose 36 to the branching position of the two water paths A and B. It is installed, and in the water passage constitution member 38, the communication portion 3 is provided on the hose connection member 4 side. With this, it is possible to miniaturize the whole when a plurality of switchable water passages A and B are built in, and at the same time ensure the connection with the hose 36.

Hereinafter, each component constituting the faucet 40 will be described.

＜Handle (stick)＞ As shown in FIGS. 1 and 2, the handle 32 is attached to the top of the body 34 of the faucet 40. With this handle 32, the mixing ratio of water and hot water is adjusted, and the water volume of the mixed water of water and hot water is adjusted. For example, by rotating the handle (rod) 32 or moving it up and down, water, such as mixed water of water and hot water, can be sprayed from the water outlet 10 of the water outlet pipe 30.

＜Main body＞ The main body 34 is fixed on the pedestal where the faucet 40 is installed, and supports the whole. The main body 34 may be made of metal or resin.

＜Hose＞ The hose 36 penetrates through the inside of the body 34 and is connected to the outlet pipe 30. In addition, the hose 36 only needs to allow the mixed water of water and hot water to pass through, and has flexibility, and it may be made of resin or metal.

＜Outlet pipe＞ The water outlet pipe 30 includes a hose connection member 4 to which a hose 36 is connected, a water passage component 38, and a cover 1 covering the hose connection member 4 and the water passage component 38. As shown in FIG. 2, the outlet pipe 30 is connected to the hose 36 and can be pulled out from the main body 34 together with the connected hose 36.

＜Hose connection member＞ The hose 36 is connected to the communication portion 3 of the water passage constituent member 38 by the hose connection member 4. Since the hose 36 has a fixed outer diameter, the hose connecting member 4 includes "a portion having a fixed inner diameter corresponding to the outer diameter of the hose". A hose is fixed in the inner diameter portion. The hose connection member 4 has a fixed outer diameter and is thicker than the water passage constituent member 38. In addition, the hose connection member 4 is arranged on the root side of the outlet pipe 30. In this way, the slenderness of the tip side can be more emphasized.

＜Cover body＞ With the cover 1, the hose connection member 4 and the water passage constituent member 38 are covered. The lid 1 may be made of resin or metal. For example, it may be composed of polymethyl methacrylate (PMMA) having excellent antifouling properties.

＜Waterway components＞ The water passage constituent member 38 includes two water passages A and B connected to the water outlet 10 and a communication portion 3 from the main water passage C side of the hose 36 to the branch position leading to the two water passages A and B. The length L1 of the water path from the water outlet portion 10 of the water path constituent member 38 to the communicating portion 3 is longer than the length L2 of the hose connection member. In addition, as shown in FIG. 3B, in the water passage constituent member 38, two water passages A and B are in the longitudinal direction of the outlet pipe 30, and the length L1 from the water outlet portion 10 to the communication portion 3 in the water passage constituent member 38 can also be occupied. More than 2/3 of the length of the water pipe 30. In this way, in the outlet pipe 30, a slim and neat design can be realized at the front end. We would like the water passage component 38 to be integrally formed, but in this case, since the communicating portion 3 accommodates movable parts such as ball valves and ball valve pushers described later, its diameter becomes at least a part (specifically, softer) than the hose connection member 4 The fixed portion of the tube 36) is larger. Therefore, due to the problem of die cutting, the water passage constituent member 38 and the hose connection member 4 cannot be integrally formed. In the faucet according to the present invention, in order to achieve a neat design where the connecting portion 3 is provided at the root, the water path constituent member 38 and the hose connecting member 4 are formed separately. In addition, the water passage constituent member 38 is preferably an integrally formed member. In this case, the water passage constituent member 38 includes the communication portion 3 from the main water passage C side to the branch position, but does not include movable portions such as ball valves and ball valve pushers.

＜Water outlet＞ The water outlet 10 is arranged on the side of the water outlet pipe 30. As shown in Figure 3, in this example, it faces the negative direction of the y-axis. Moreover, as shown in FIG. 5, FIG. 8, and FIG. 11, the water outlet part 10 is provided with the hole 10a for a flat water outlet in the center, and the hole 10b for sprinkling water is provided in the periphery. The spray outlet hole 10b is connected with the spray outlet A, and the straight outlet hole 10a is connected with the straight outlet B. In addition, in order to prevent water leakage and the like, a spout gasket 11, an O-ring 18, and the like are provided.

＜Two waterways＞ As shown in Figures 4A and 4B, two waterways A and B are provided inside the outlet pipe 30, which are sprayed water (first waterway) A branched from the main waterway C at the bottom and straight water outlet (second waterway). ) B. The longitudinal direction (z-axis direction) of the spray water A and the longitudinal direction (z-axis direction) of the straight water B are preferably arranged in parallel to each other. In addition, as shown in FIG. 4B, the spray water A and the straight water B are arranged along the y-axis direction. In addition, a gasket 9 is provided in order to prevent water leakage and the like.

＜Connecting part＞ As shown in Figures 7, 10, and 12, a movable part is housed in the communicating part 3, and the movable part is the sprinkling water (first water path) A and the flat water branching from the main water path C from the hose 36 Switch between the two waterways A and B that directly exit the water (second waterway) B. The movable part includes the rotating shaft 5, the ball valve 12 and the ball valve pushing member 26. Specifically, in the communication portion 3, the ball valve 12 is supported by the ball valve pusher 26 that rotates around the rotating shaft 5. With this ball valve 12, one of the openings leading to the spray water A or the straight water B is blocked, and the other of the straight water B or the spray water A is selected.

＜Switching mechanism＞ In addition, the outlet pipe 30 includes, for example, a button 2, a cam mechanism 27, and an alternate mechanism 28 as a switching mechanism for switching the two water channels A and B in the communication portion 3. The cam mechanism 27 is directly or indirectly connected to the button 2 and simultaneously connected to the valve body (ball valve) 12. With the cam mechanism 27, in response to the pressing of the button 2, the valve body (ball valve) 12 switches between the spray water A and the straight water B. In addition, the alternate mechanism 28 is directly or indirectly connected to the button 2 and holds the state when the button 2 is pressed. As shown in FIG. 5, the alternating mechanism 28 and the cam mechanism 27 are arrange|positioned in parallel with each longitudinal direction (z-axis direction), for example. Thereby, the alternating mechanism 28 and the cam mechanism 27 are separated, and the respective longitudinal directions (z-axis direction) are arranged in parallel. Thereby, the whole water outlet pipe 30 can be miniaturized.

In addition, as shown in FIGS. 4A and 4B, the alternate mechanism 28 and the cam mechanism 27 can also sandwich the spray water A and the straight water B. Also, in this case, "the longitudinal direction (z-axis direction) of the alternate mechanism 28 and the cam mechanism 27" and "the longitudinal direction (z-axis direction) of the spray water A and the straight water B" are preferably essential Are arranged parallel to each other. Thereby, they can be arranged in the outlet pipe 30 in a well-balanced manner. In addition, the direction in which the spray water A and the straight water B are arranged (y-axis direction), and the direction in which the alternating mechanism 28 and the cam mechanism 27 are arranged (x-axis direction) can be any of the following: the same direction When the respective directions cross each other, and the respective directions are perpendicular to each other. The alternate mechanism 28 and the cam mechanism 27 only need to be appropriately arranged in accordance with the cross-sectional structure of the inside of the outlet pipe 30.

＜Connecting part＞ The connection part 7 is connected to the button 2. When the button 2 is pressed, the connection part 7 will move downward (z-axis negative direction). The connecting portion 7 includes an extended rod-shaped first connecting portion 7a and a rod-shaped second connecting portion 7b as bifurcated branches. The first connecting portion 7a is connected to the alternate mechanism 28. In addition, the second connecting portion 7b is connected to the cam mechanism 27. If the button 2 is pressed to move the connecting portion 7 downward (z-axis negative direction), the first connecting portion 7a and the second connecting portion 7b will also move downward (z-axis negative direction). Along with this, the alternate mechanism 28 connected to the first connection portion 7a and the cam mechanism connected to the second connection portion 7b move downward (z-axis negative direction), respectively. In addition, the connecting portion 7 does not necessarily need to have parts in common with the alternate mechanism 28 and the cam mechanism 27. For example, the first connecting portion 7a connected to the alternating mechanism 28 and the second connecting portion 7b connected to the cam mechanism 27 may be separately provided and directly connected to the button 2 respectively. In addition, as shown in FIGS. 3 and 4B, by connecting the pusher 8, the fluctuation of the first connection portion 7a and the second connection portion 7b other than the longitudinal direction can also be suppressed.

＜Alternative mechanism＞ The alternate mechanism 28 is directly or indirectly connected to the button 2 and holds its state when the button 2 is pressed. That is, with the alternate mechanism 28, the following two states can be selected: a state in which the button 2 is pressed, and a state in which the button 2 is not pressed. In addition, the alternate mechanism 28 can switch the above-mentioned states. The state where the button 2 is not pressed is the case where the spray water A is selected as shown in FIGS. 4B and 6, and the state when the button 2 is pressed is the case where the flat water B is selected as shown in FIG. 9. The alternate mechanism 28 is connected to the first connecting portion 7 a by a split pin 16 and includes an alternate mechanism support portion 20, a blade member 21, a rod 22, a knocking member 23, and a knocking member pressing spring 24. In addition, the alternate mechanism 28 can also be configured in a manner that "when the button 2 is pressed multiple times, the holding state is released." Moreover, in this case, when the button 2 is pressed an odd number of times, the state of pressing the button 2 may be maintained. Furthermore, in order to release the pressed state, the above-mentioned knocking member pressing spring 24 and the connecting portion pressing spring 25 are provided.

＜Cam mechanism＞ The cam mechanism 27 is directly or indirectly connected with the button 2 and at the same time connected with the valve body (ball valve) 12, which corresponds to the pressing of the button 2, and the valve body (ball valve) 12 switches between spraying water A and straight water B. As shown in Figures 5, 6, 8 and 9, the cam mechanism 27 can convert the linear motion generated by the pressing of the button 2 into an axis parallel to the direction of the pressing (the negative direction of the z-axis), for example. z axis) as the center of the rotational movement. In addition, the rotation axis of the rotary motion only needs to be an axis parallel to the pressing direction, and it is not limited to the case where it is coaxial with the linear motion generated by the pressing. For example, the central axis of the cover 1 can also be used as the rotation axis.

The cam mechanism 27 shown in FIGS. 5, 6, 8 and 9 is composed of a cam 6 having a protruding portion 6a and a cam receiving portion 29 provided with a slit 29a inclined with respect to the shaft. The connecting portion 7b is connected. In the axial direction, if the cam receiving portion 29 moves downward (z-axis negative direction), the protrusion 6a of the cam 6 will slide obliquely with respect to the shaft (z-axis) along the slit 29a provided in the cam receiving portion 29 Move, and the cam 6 will rotate along the rotation axis (z axis) 5. In this way, the linear motion in the axis direction generated by the pressing of the button 2 can be converted into a rotational motion centered on the axis (z-axis). In addition, the direction of the inclined slit 29a of the cam mechanism is not limited to the case where it is provided in the left spiral direction along the z-axis direction as shown in FIG. 5 and the like. For example, it may be provided in the right spiral direction along the z-axis direction.

＜Valve body (ball valve), ball valve pusher, rotating shaft (pendulum)＞ The rotating shaft 5 is connected to the cam 6, and the rotating shaft 5 is also rotated by the rotation of the cam 6. In addition, the rotating shaft 5 is connected to the ball valve pusher 26 in the communication portion 3. The ball valve pushing member 26 supports the ball valve pushing spring 14, the ball valve receiving portion 13 and the ball valve 12. The ball valve 12 is also called a ball valve. The ball valve 12 is biased upward (positive direction of the z-axis) by the ball valve urging spring 14. The ball valve pushing member 26 rotates in the communicating portion 3 by the rotation of the rotating shaft 5, and the ball valve 12 supported by it will spray either the opening of the water A or the opening of the flat water B Block, and choose another straight water B or spray water A that forms an opening. When the ball valve 12 moves between the opening of the spray water A and the opening of the flat water B, it will move up and down, but since the ball valve 12 is biased upward, it can move stably between the two openings. In the initial position where the rotating shaft 5 is not rotating, the ball valve 12 blocks the opening to the straight water outlet B. In addition, in order to prevent water leakage and the like, a ring 15, an O-ring 17 and the like are attached to the rotating shaft 5. In addition, an O-ring 19 is provided between the communication portion 3 and the hose connection member 4.

Hereinafter, the spraying water state, the straight watering state, and the intermediate state of the water outlet pipe 30 will be described.

＜Spray water＞ Figure 5 shows the internal structure of the outlet pipe 30 after the cover 1 is removed, and the cam mechanism 27, the alternate mechanism 28, and the communicating part 3 in the state where the button 2 is not pressed (spraying water) are internally seen through perspective. 6 is an enlarged partial perspective view of the bottom of the cam mechanism 27, the alternate mechanism 28, and the communicating portion 3 including the cam mechanism 27 of the outlet pipe 30 after the cover 1 is removed in FIG. FIG. 7 is a schematic diagram showing the branch from the main water path C as the spouting water A when the communication portion 3 of the outlet pipe 30 of FIG. 5 is viewed from the main water path C side. When the button 2 is not pressed, the protrusion 6a of the cam 6 does not slide on the slit 29a of the cam receiving portion 29, and the rotating shaft 5 does not rotate. In this case, the ball valve pushing member 26 is located at the initial position, and the ball valve 12 blocks the opening of the straight water outlet B. Therefore, the opening of the spray water A is selected.

＜Straight water outlet＞ Figure 8 shows the internal structure of the outlet pipe 30 after the cover 1 is removed, and the cam mechanism 27, the alternate mechanism 28 and the communicating portion 3 in the state of pressing the button 2 (straight outlet B) are internally seen through perspective. FIG. 9 is an enlarged partial perspective view of the bottom of the cam mechanism 27, the alternate mechanism 28, and the communicating portion 3 including the cam mechanism 27 of the outlet pipe 30 after the cover 1 is removed from FIG. FIG. 10 is a schematic diagram showing the branch from the main waterway into a straight water outlet B when the communicating portion 3 of the outlet pipe 30 of FIG. 8 is viewed from the side of the main waterway C. In the state where the button 2 is pressed (flat water B), the protrusion 6a of the cam 6 slides and moves on the slit 29a of the cam receiving portion 29, and the rotation shaft 5 also rotates. In this case, the ball valve pushing member 26 will also rotate, and the ball valve 12 will block the opening of the spray water A. Therefore, it becomes a state where the straight water B is selected.

＜The intermediate state between spray water and straight water＞ Figure 11 shows the internal structure of the water outlet pipe 30 after the cover 1 is removed, and the cam mechanism 27 and the alternate mechanism for the state from the state of never pressing the button 2 to the state of being pressed (spraying water→straight watering) 28. A partial perspective view of the communication part 3 through internal perspective. Fig. 12 is a schematic view showing that the branch from the main water channel C is located between the spray water A and the straight water B when the communication portion 3 of the water outlet pipe 30 of Fig. 11 is viewed from the main water channel C side.

In the state where the button 2 is slightly pressed (the intermediate state between the spray water A and the straight water B), the protrusion 6a of the cam 6 slides slightly on the slit 29a of the cam receiving portion 29 and moves, and the rotating shaft 5 also slightly moves. Spin. In this case, the ball valve pushing member 26 will also rotate slightly, and the ball valve 12 will be located between the opening of the spray water A and the opening of the flat water B. Therefore, it becomes a state where both the spray water A and the straight water B are selected at the same time. In addition, since this state of slightly pressing the button 2 is not a state that can be held by the alternate mechanism 28, when the hand is removed from the button 2, it will return to the original state where the button 2 is not pressed.
