Description

The present invention relates to a faucet fixture capable of switching between a plurality of types of flowing water to be discharged, such as raw water and purified water.

As such a faucet fixture, for example, there is a technique shown in Japanese Patent Application Laid-Open No. 2004-082031 (Patent Document 1).

This faucet device can switch the type of flowing water to be discharged between purified water and raw water, and has a mechanism for displaying the type of discharged water to be displayed on a window provided on the cover. A window is formed near the tip of the cover of the faucet fixture, and the display of purified water and raw water displayed on the curved surface of the display body composed of about a quarter of a cylinder alternates from this window. Is displayed in.

The display body has a shaft portion formed in both directions from the side surface of the fan shape, and this shaft portion is rotatably supported by a support portion formed on the faucet body. A torsion spring is attached to one side of the shaft portion, and the display body is urged so that the display body falls toward the tip side of the faucet device while taking a reaction force against the faucet body.

This display is driven by a push button that switches the water discharge. The push button is provided to operate in a push-push manner with respect to the faucet body. The faucet body is provided with a valve mechanism for switching water discharge, and this valve mechanism is provided with a known push-push type switching mechanism. The push button is linked with the push member of the return mechanism, and when the push button returns from the push position to the protruding position, the spring-loaded force of the return mechanism is used.

An inclined cam portion is provided on the ceiling of the push button, and an action portion with which the cam portion comes into contact is provided at the lower part of one display body. When the push button is in the protruding position, this inclined portion pushes up the acting portion of the display body, and "raw water" is displayed on the window portion. When the push button is pushed in, the cam portion moves to the inner part in the pressing direction, and the pushing up of the acting portion is released. As a result, the display body is rotated by the urging force of the torsion spring so as to fall to the side where the cam portion has existed until then, and the display is switched to "purified water".

When returning the push button to the protruding position, push the push button slightly. As a result, the push-push mechanism works, and the push button is pushed back by the urging force of the spring. As a result, the cam portion of the push button pushes up the acting portion of the display body again, and the display is returned to "raw water".

As described above, in the conventional faucet fixture, the urging force of the torsion spring or the spring of the switching mechanism is used when the display body is switched to any side.

Further, in the prior art, a cam portion and an action portion for rotating the display body are provided between the push button and the display body.

According to the description of Patent Document 1, as a result of these configurations, the display unit can be provided at a position away from the reciprocating push button. Moreover, the configuration is simple, and the necessary parts are only the display body, the spring member, the display body support member, the display window, and the like, and it is said that a compact and inexpensive display device can be obtained.

Japanese Unexamined Patent Publication No. 2004-082031

As described above, in the above-mentioned conventional technique, a cam portion and an action portion for rotating the display body are provided between the push button and the display body. Further, a shaft portion for rotating the display body is provided directly below the vicinity of the side surface of the display body. Therefore, the water that has entered the inside from the window portion easily reaches these cam portions and shaft portions, and accumulates as stains such as water stains on these portions with use.

As a result, the rotation operation of the display body may not be smooth, or an error may occur in the stop position of the display body, so that the display such as "raw water" provided on the display body may not be displayed at an appropriate position on the window. Inconvenience was occurring.

Further, since the conventional faucet device has a rotation mechanism on the back surface side of the display body, even if an attempt is made to improve the visibility of the display body, the head portion of the faucet device has a predetermined size limitation. There is a limit to the enlargement of the display body.

Therefore, there is still room for improvement in the structure of the display body and the like even if the visual function of the display body is to be improved due to the problem of reliability of the operation of the display body and the problem of the size of the display body.

In view of such a situation, it has been conventionally desired to provide a faucet fixture that is compact as a whole and can surely exhibit a water discharge switching display function.

(Characteristic composition)
The characteristic configuration of the faucet fixture according to the present invention is
A faucet body with multiple channels inside and a window on the cover,
An operating body provided on the faucet body so that the faucet body can be moved in and out while holding the arm portion integrally, and an operating body that switches between the plurality of flow paths.
A supported portion that is supported by a support portion provided on the faucet body so that its posture can be changed, and a supported portion that is provided in a state in which a part of the faucet is in contact with or slightly separated from the arm portion, and is provided from the arm portion. It is provided with a cam portion that receives a pressing force, and a display body that sequentially exposes a display surface indicating a switching state of the plurality of flow paths to the window portion in response to an operation of moving in and out of the operating body.
In a directional view facing the display surface, the cam portion and the supported portion of the edge portion of the display surface have the cam portion and the supported portion with respect to the pair of the edge portions that are perpendicular to the position change direction of the display surface and face each other. It is at a point provided on the outside of the pair of the edges.

(effect)
If water enters through the window when using the faucet fixture, the water will flow downward with respect to the display surface. Since the normal installation posture of the faucet device is fixed, the flow path of water is also fixed to some extent. However, since the display body moves relative to the window portion, the water that has entered the window portion easily flows along the position change direction of the display body.

Therefore, as in this configuration, in the display body, the cam portion and the supported portion that receive the pressing force by the arm portion provided on the operating body are provided on the outside perpendicular to the display surface in the direction of changing the position of the display surface. The chances of water reaching these sites can be reduced. As a result, a clean state is maintained without water stains on the working portion and the supported portion, and the display position of the display surface with respect to the window portion is properly maintained.

(Characteristic composition)
The faucet fixture according to the present invention includes
A faucet body with multiple channels inside and a window on the cover,
An operating body provided on the faucet body to switch between the plurality of flow paths, and an operating body.
A shaft portion rotatably supported by a support portion provided on the faucet body and a cam portion pressed by the operating body are provided, and the plurality of flow paths of the plurality of flow paths can be operated according to the operation of the operating body. A display body that sequentially exposes a display surface indicating a switching state to the window portion is provided.
In the direction view facing the display surface, the display is such that the cam portion is located outside the pair of edge portions of the display surface that are perpendicular to the position change direction of the display surface and face each other. The shaft portion may extend from the body and further extend from the cam portion .

(effect)
In order for the display surface to be fixed at an appropriate position with respect to the window portion, it is necessary to prevent water stains and the like from accumulating on parts that affect the operation of the display body, such as the cam portion and the shaft portion. In particular, when dirt accumulates on the shaft portion, resistance is generated between the shaft portion and the support portion, and the display body may stop at an unplanned position. As a result, the function of displaying the water discharge state is impaired. Therefore, in this configuration, the shaft portion, which is particularly necessary to prevent dirt, is set at the position farthest from the display surface where water easily enters.

(Characteristic composition)
In the faucet device according to the present invention, a partition portion intersecting the shaft portion may be provided between the shaft portion and the cam portion.

(effect)
By providing the partition portion as in this configuration, even if water flows down from the display surface to the cam portion, it is possible to surely prevent the water from reaching the shaft portion.
Further, by providing the cam portion and the shaft portion via such a partition portion, the partition portion serves as a connecting member for connecting and configuring the two, and the degree of freedom in determining the structure of the display body is increased. Therefore, it becomes easy to configure the display body according to the shape of the faucet body and the like.

(Characteristic composition)
In the faucet device according to the present invention,
A faucet body with multiple channels inside and a window on the cover,
An operating body provided on the faucet body to switch between the plurality of flow paths, and an operating body.
The support portion provided on the faucet body has a supported portion that is supported so as to be able to change its posture, and an action portion that receives an operating force from the operating body. A display body that sequentially exposes a display surface indicating a switching state of the flow path of the above to the window portion is provided.
In a directional view facing the display surface, the acting portion and the supported portion have an action portion and a supported portion with respect to a pair of the edge portions of the display surface facing in the direction of changing the position of the display surface. It is provided on the outside of the pair of the edges and
The display surface has a first radius of curvature along the position change direction and a second radius of curvature along the direction orthogonal to the position change direction, and the first radius of curvature is shorter than the second radius of curvature. It is convenient if it is configured.

(effect)
With this configuration, the entire display surface can be curved. The external shape of the faucet body can be configured to be spherical, for example, or can be configured into any shape by combining various curved surfaces. In that case, by making the shape of the display surface curved in two directions perpendicular to each other, it becomes easy to make the display surface follow the shape of the outer surface of the faucet body. Therefore, when the display unit is exposed to the window portion provided on the cover of the faucet body, the entire display unit approaches the surface of the faucet body and the visibility is improved.

Further, by making the radii of curvature in the two directions different, and in particular, by shortening the first radius of curvature in the position changing direction of the display surface, even if water infiltrates from the display surface, the water changes the position of the display surface. It flows to the edge on the side along the direction. Since there are no acting portion and supported portion on this edge portion, dirt is prevented from accumulating on the supported portion and the like, and a good switching operation of the display body can be maintained for a long period of time.

(Characteristic composition)
In the faucet device according to the present invention,
A faucet body with multiple channels inside and a window on the cover,
An operating body provided on the faucet body to switch between the plurality of flow paths, and an operating body.
The support portion provided on the faucet body has a supported portion that is supported so as to be able to change its posture, and an action portion that receives an operating force from the operating body. A display body that sequentially exposes a display surface indicating a switching state of the flow path of the above to the window portion is provided.
In a directional view facing the display surface, the acting portion and the supported portion have an action portion and a supported portion with respect to a pair of the edge portions of the display surface facing in the direction of changing the position of the display surface. It is provided on the outside of the pair of the edges and
When the window portion has four opening edges and a pair of the opening edges extending while intersecting in the position changing direction of the display surface among the opening edges is used as an intersecting opening edge. It can be configured so that the central side of the intersecting opening edge portion located on the lower side in the vertical direction of the opening edge portion spreads outward along the position changing direction.

(effect)
As in this configuration, of the pair of intersecting opening edges that intersect in the position change direction, which is the opening edge of the window, the center of the lower intersecting opening edge that intersects in the position change direction is inflated outward. By doing so, for example, when water enters the inside of the faucet body from the display portion, the intrusion position can be guided to the central portion of the cross opening edge portion. That is, although the window portion is formed on the surface of the faucet body, it is often provided slightly upward so that the user can easily see it. In that case, the central position of the intersection opening edge is the lowest in the vertical direction. Even if water enters the inside of the faucet body from this position, the position is a position away from the working portion and the supported portion. Therefore, the infiltrated water is prevented from adhering to the acting portion and the supported portion, and the smooth movement of the display body is maintained for a long period of time.

(Characteristic composition)
The faucet device according to the present invention
A faucet body with multiple channels inside and a window on the cover,
An operating body provided on the faucet body to switch between the plurality of flow paths, and an operating body.
The support portion provided on the faucet body has a supported portion that is supported so as to be able to change its posture, and an action portion that receives an operating force from the operating body. A display body that sequentially exposes a display surface indicating a switching state of the flow path of the above to the window portion is provided.
In a directional view facing the display surface, the acting portion and the supported portion have an action portion and a supported portion with respect to a pair of the edge portions of the display surface facing in the direction of changing the position of the display surface. It is provided on the outside of the pair of the edges and
Of the edge portions constituting the display surface, at least one of the acting portion and the supported portion is formed on the pair of the edge portions facing in the direction orthogonal to the position changing direction. It is convenient that the portion is provided with a water blocking portion for preventing water from reaching the acting portion or the supported portion.

(effect)
By providing the water blocking portion as in this configuration, it is possible to reliably prevent water from flowing to the acting portion and the supported portion via the display portion. Therefore, the smooth movement of the display body is maintained even better.

(Characteristic composition)
In the faucet device according to the present invention, as the configuration of the water stop portion, a pair of edge portions constituting the display surface and facing in a direction orthogonal to the position changing direction and the edge portion are included. It is convenient that the distance from the inner surface of the facing cover is set shorter than the distance between the portion different from the edge portion on the display surface and the inner surface facing the portion.

(effect)
In this configuration, attention is paid to the distance between each part of the display surface and the inner surface of the cover, and in particular, the distance from the inner surface of the cover is about the edge portion of the edge portion of the display surface in the vicinity where the acting portion and the supported portion are provided. To shorten. As a result, even if water tries to infiltrate through the window portion, the movement of water is blocked by the effect of surface tension or the like at the edge portion having a narrow interval.

[First Embodiment]
The faucet fixture of the present invention is characterized by a water discharge switching display mechanism provided at the tip of the faucet main body J1 having a fluid flow path. The switching display mechanism selectively exposes each display to the window portion W provided on the cover C of the faucet fixture when the raw water or purified water is switched and discharged. Hereinafter, embodiments of the faucet fixture according to the present invention will be described with reference to the drawings.

(Overview)
The appearance of the faucet fixture according to this embodiment is shown in FIG. A cover C is provided at the tip of the faucet body J1 to cover most of the faucet body, and the overall appearance is simply finished. This prevents dirt from accumulating at the joints of the cover C and the like. Specifically, the upper portion is covered by the first cover C1 and the lower portion is covered by the second cover C2. The joint between the first cover C1 and the second cover C2 is located near the top of the tip portion to prevent water from splashing as much as possible.

At the joint between the first cover C1 and the second cover C2, an operating body 1 for switching the discharged water between, for example, purified water and raw water is provided. The operating body 1 is a so-called push-push type push button, and is connected to a known switching mechanism K provided in the faucet main body J1 as shown in FIGS. 2 and 3.

A window portion W indicating the type of water discharge switched by the operating body 1 is formed on the upper surface of the first cover C1. From the window portion W, a display surface 41 indicating a water discharge state such as "raw water" or "purified water" is exposed.

On the other hand, a circular opening is provided below the second cover C2, and a screen member 7 for switching the water discharge shape to a shower shape or a straight shape is fitted. The screen member 7 is provided with a lever 6 for rotation operation, and a scale 61 indicating the position of the lever 6 is provided on the side surface of the second cover C2.

(Display body)
FIG. 3 is an exploded perspective view showing the structure of the display body S for switching and displaying the water discharge type. The display body S rotates over a predetermined angle and changes its posture according to the exit / exit operation of the operating body 1. The display body S according to the present embodiment includes a display body 2 supported by the faucet body J1 and a display board 4 attached to the display body 2.

The display main body 2 is rotatably supported by the support portion J2 of the faucet main body J1 by a pair of shaft portions 22a provided as the supported portions 22. Further, the display main body 2 is provided with an action unit 21 that receives an operation force from the operation body 1. In the present embodiment, the acting portion 21 is configured as a cam portion 21a pressed by the arm portion 12 of the operating body 1.

As shown in FIG. 3, the shaft portion 22a is provided outward with respect to the working portion 21. This is to maintain the rotational operation of the display body S smoothly. The quality of the sliding state between the shaft portion 22a and the support portion J2 is affected by the degree of dirt such as water stain on the shaft portion 22a. When dirt accumulates on the shaft portion 22a, resistance is generated between the shaft portion 22a and the support portion J2, and the display body S may stop at an unscheduled position. As a result, the function of displaying the water discharge state is impaired. Since most of the water reaching the shaft portion 22a enters from the upper window portion W, the position of the shaft portion 22a is kept away from the position vertically below the window portion W by arranging the action portion 21 in between.

Further, a plate-shaped partition portion 23 intersecting the shaft portion 22a is provided between the action portion 21 and the shaft portion 22a. The partition portion 23 is configured in a flange shape overhanging with respect to the connecting portion with the acting portion 21, and in particular, with respect to the connecting portion with the acting portion 21, regardless of the posture of the acting portion 21. It is configured to project upward in the vertical direction. As a result, water is more reliably prevented from reaching the shaft portion 22a along the acting portion 21. The partition portion 23 also has a function of deviating the shaft portion 22a with respect to the overall shape of the display body 2. By setting the distance between the display surface 41 and the shaft portion 22a, which will be described later, the rotation locus of the display surface 41, the radius of curvature of the display surface 41, and the like are determined.

A torsion spring 3 is attached to one of the partition portions 23 as shown in FIGS. 3 and 4. The torsion spring 3 urges the display main body 2 so that the display main body 2 falls toward the tip end side of the faucet main body J1. The torsion spring 3 is, for example, a toggle spring, and the winding portion is inserted into the shaft portion 22a. One end is locked to the spring receiving portion 24 provided in the partition portion 23, and the other end is locked to the reaction force receiving portion J4 of the faucet main body J1.

Further, at least the partition portion 23 on the side where the spring receiving portion 24 is formed is provided with a stopper 25 that regulates the amount of rolling of the display main body 2 toward the tip end side. The stopper 25 comes into contact with a part of the support portion J2 provided on the side of the faucet main body J1. In this state, for example, "raw water" described on the display surface 41 described later is displayed from the window portion W.

The arm portion 12 of the operating body 1 comes into contact with the acting portion 21 of the display body 2, and the display body S is rotated. The operating body 1 projects at a boundary position between the first cover C1 and the second cover C2, and is connected to a switching mechanism K provided in the faucet main body J1. The operating body 1 is connected to the switching mechanism K by engaging the hole portion 13 formed in the operating body 1 with the protrusion K2 of the switching mechanism K. However, the operating body 1 transmits the force to the switching mechanism K only on the back surface of the operating body 1. By pushing the operating body 1, the back surface of the operating body 1 pushes the end surface of the operating shaft K1 of the switching mechanism K, and the operating body 1 shifts from the protruding position to the pushing position. On the contrary, when returning the operating body 1 to the protruding position, the operating body 1 is pushed in once, the return spring of the push / push mechanism is activated to project the operating shaft K1, and the back surface of the operating body 1 is further pushed out.

The material of the display body 2 is, for example, a polyacetal resin (POM material) or the like. Since the cam portion 21a of the display main body 2 slides on the operating body 1 and the shaft portion 22a is in sliding contact with the support portion J2 of the faucet main body J1, it is preferable to use a material resistant to wear.

(Operating body)
The operating body 1 is provided with an arm portion 12 that presses the cam portion 21a of the display main body 2. FIG. 3 shows an example in which a pair of cam portions 21a is provided, whereas the arm portion 12 is one. This is to simplify the structure of the operating body 1, but the operating body 1 may be provided with two arm portions 12. In that case, the pushing operation on the display body 2 is reliable.

(Display board)
As shown in FIG. 3, a cylindrical display surface 41 and a display plate 4 having a fan-shaped side surface are arranged on the display main body 2 so as to be overlapped with each other. Claws 26 are projected on both side surfaces of the display body 2, and locking holes 42 provided on the side surfaces of the display plate 4 engage with the claws 26. The display plate 4 is made of, for example, a resin member such as a transparent polycarbonate material. Switching displays such as "raw water" and "purified water" are printed on the back side of the display surface 41. By providing the display on the back surface in this way, it is possible to prevent the display plate 4 from being rubbed against the back surface of the first cover C1 and peeled off.

By assembling the display main body 2 and the display board 4 as in this configuration, a slight gap is generated between the back surface of the side surface of the display board 4 and the side surface of the display main body 2. When water enters from the window portion W, the water reaches the side surface through the edge portion 43 or the like of the display plate 4 and enters the gap through the locking hole 42 or the like. That is, by providing a gap between the display body 2 and the display board 4, the effect of retaining the infiltrated water can be expected. Therefore, with this configuration, it is possible to more reliably prevent the infiltrated water from reaching the working portion 21 and the shaft portion 22a.

In addition, unlike this embodiment, the display main body 2 and the display board 4 may be integrally formed. The integral molding reduces the number of parts and allows some cost savings. Further, if the display is provided on the surface, inconveniences such as fogging of the display surface 41 cannot occur, and the visibility of the display plate 4 can be expected to be improved. However, in that case, since it is necessary to provide a display of "raw water" on the front surface of the display board 4, it is necessary to set the dimensions so as to prevent the display surface 41 from rubbing against the back surface of the first cover C1. Become.

In the display main body 2 of the present embodiment, in the direction view facing the display surface 41, among the edge portions 43 of the display surface 41, the pair of edge portions 43 perpendicular to and facing the position change direction Y of the display surface 41 On the other hand, the action portion 21 and the shaft portion 22a are provided on the outside of the pair of edge portions 43.

This is a structure for suppressing the accumulation of dirt on the working portion 21 and the shaft portion 22a. If water enters from the window portion W when using the faucet fixture, the water flows downward with respect to the display surface 41. Since the normal installation posture of the faucet device is fixed, the path through which water flows down is also fixed to some extent. However, since the display body S moves relative to the window portion W, the water that has entered the window portion W tends to flow along the position change direction Y of the display body S. Incidentally, the position changing direction Y of the display body S means the direction in which the display body 2 rotates around the shaft portion 22a, as shown in FIG.

Therefore, as in this configuration, by providing the working portion 21 and the shaft portion 22a on the outside perpendicular to the position changing direction Y of the display surface 41 with respect to the display surface 41, the chance of water reaching these parts is reduced. Can be done. As a result, the working portion 21 and the shaft portion 22a are maintained in a clean state without water stains, and the display position of the display surface 41 with respect to the window portion W is properly maintained.

(Operation mode of display body)
FIG. 4 shows an operation mode of the display main body 2 when the operating body 1 is pushed in. When the operating body 1 is in the protruding position (upper view of FIG. 4), the arm portion 12 of the operating body 1 is in contact with or slightly separated from a part of the cam portion 21a (acting portion 21). In this state, the stopper 25 provided on the partition portion 23 of the display main body 2 is in contact with the vicinity of the support portion J2 of the faucet main body J1, and the display main body 2 is in the front limit position. After that, the display main body 2 rotates about the shaft portion 22a in response to the pushing of the arm portion 12. At this time, a torsion spring 3 is wound around the shaft portion 22a, and the respective ends of the torsion spring 3 are a spring receiving portion 24 provided in the partition portion 23 and a reaction force receiving portion J4 of the faucet body J1. The torsion spring 3 exerts an urging force so as to rotate the display body 2 in the counterclockwise direction in FIG. Therefore, the force required for the operation of the operating body 1 is equal to the resultant force of the force on the spring provided in the switching mechanism K and the force on the torsion spring 3 of the display main body 2.

FIG. 4 When the operating body 1 and the arm portion 12 are pushed in from the state shown in the above figure, the display main body 2 rotates, and the surface angle of the cam portion 21a changes with respect to the pushing direction of the arm portion 12. The lower figure of FIG. 4 shows a state in which the pushing of the operating body 1 is completed, and it can be seen that the angle of the cam portion 21a is greatly inclined with respect to the pushing direction of the arm. In this state, the torsion spring 3 generates the maximum urging force. Therefore, coupled with the inclination angle of the cam portion 21a, the arm portion 12 in the lower figure of FIG. 4 tends to bend so as to escape upward. Therefore, as shown in FIG. 4, a regulating portion J3 for restricting the arm portion 12 from escaping to one side is provided in the faucet main body J1.

By providing the restricting portion J3, the shape of the arm portion 12 can be made thinner or thinner. Therefore, it is possible to provide the switching mechanism K that effectively utilizes the internal space of the first cover C1 whose size is limited.

FIG. 4 The lower figure shows a state in which the arm portion 12 has been pushed in. At this time, the cam portion 21a of the display main body 2 is in contact with the tip of the arm portion 12 by the urging force of the torsion spring 3. At this time, the display of "purified water" written on the display surface 41 is exposed from the window portion W. That is, as for the posture of the display main body 2 in the state where the operating body 1 is pushed in, the positions of the operating body 1 and the arm portion 12 are determined according to the position on the pushing side of the switching mechanism K, and the posture of the cam portion 21a applied to this is determined. Is determined by. Therefore, in order to accurately expose the display of "purified water" to the window portion W, it is necessary to determine the dimensions or the mounting position of the arm portion 12 and the cam portion 21a extremely accurately.

(Water stop)
The display switching mechanism for the type of water discharge of the present embodiment is provided with a water stop portion 5 for preventing water from entering the acting portion 21 and the shaft portion 22a of the display main body 2. For example, as shown in FIG. 5, of the edge portions 43 constituting the display surface 41, the pair of edge portions 43 facing in the direction orthogonal to the position changing direction Y, that is, along the extending direction of the shaft portion 22a. A water stop portion 5 is provided at an edge portion 43 in which at least one of the action portion 21 and the shaft portion 22a is formed.

Specifically, the distance between the pair of edge portions 43 and the inner surface of the first cover C1 on which the edge portions 43 face is different from that of the edge portion 43 of the display surface 41, and the first cover facing the portion. It is set shorter than the distance from the inner surface of C1. Therefore, as shown in FIG. 5, an inner convex portion 51 is provided on the back surface of the first cover C1 along the inner circumference of the window portion W.

That is, paying attention to the distance between each part of the display surface 41 and the inner surface of the first cover C1, in particular, regarding the edge portion 43 of the edge portion 43 of the display surface 41 in the vicinity where the action portion 21 and the shaft portion 22a are provided. The distance from the inner surface of the first cover C1 is shortened. As a result, even if water tries to infiltrate through the window portion W, the movement of water is prevented by the effect of surface tension or the like at the edge portion 43 having a narrow interval. Therefore, the working portion 21 and the shaft portion 22a can be kept clean, and the smooth movement of the display body S is maintained satisfactorily.

In order to prevent water from entering the shaft portion 22a or the like from the window portion W, the distance between the inner surface of the first cover C1 and the display surface 41 may be set as follows, for example.

As shown in FIG. 6, the distance between the portion of the display surface 41 that is not the edge portion 43 and the inner surface of the first cover C1 is H1 (mm), and the side of the display surface 41 where the action portion 21 or the like is provided. Assuming that the distance between the edge portion 43 and the inner surface of the first cover C1 is H2 (mm), the value of (H1-H2) is preferably 0.05-2. If it is smaller than this, it becomes difficult to exert the water stopping function at the edge portion 43 by making the gap size different. Further, by reducing the gap dimension in the portion other than the edge portion 43, the display surface 41 may be deformed due to the repeated operation of the display main body 2 or the relative position between the display plate 4 and the first cover C1 may be changed. Is likely to interfere with the inner surface of the first cover C1. In order to prevent such inconvenience, the value of (H1-H2) is preferably 0.1 or more, particularly 0.2 or more.

On the other hand, when the value of (H1-H2) is larger than 2, the display surface 41 becomes a position recessed from the window portion W, and the visibility of the display surface 41 deteriorates. However, even if it is smaller than 2, it is preferable to set it to 1.0 or less, particularly 0.5 or less, in order to further improve the visibility. As a result, the value of (H1-H2) is preferably 0.3.

The value of H1 is preferably 0.2 to 1.8. If it is less than that, the display surface 41 is likely to be scratched when the display body 2 is deformed due to repeated use or when the relative position between the display surface 41 and the inner surface of the first cover C1 changes. Therefore, it is better to set it to 0.3 or more, particularly 0.5 or more. Further, if the value of H1 becomes excessive, the display surface 41 becomes a position deeper than the window portion W, and the visibility of the display deteriorates. Therefore, the value of H1 is preferably 1.5 or less, particularly 1.0 or less. As a result, it is preferably about 0.8.

The value of H2 is preferably 0.1 to 1.5. If it is less than that, the edge 43 and the inner surface of the first cover C1 are likely to interfere with each other due to deformation of the display body 2 over time, and the operation of the display body 2 may be impaired. Therefore, it is better to set it to 0.2 or more, especially 0.3 or more. On the other hand, when the value of H2 becomes large, it becomes difficult to exert the water stopping function by narrowing the gap. Therefore, it is better to further set it to 1.0 or less, particularly 0.6 or less. As a result, it is preferably about 0.5.

In the present embodiment, the shape of the display surface 41 also has the following features in order to prevent water that has entered the inside of the first cover C1 from the window portion W from reaching the working portion 21 and the shaft portion 22a. I'm letting you. That is, the display surface 41 has a first radius of curvature R1 related to the curvature along the position change direction Y of the display surface 41 and a second radius of curvature R2 related to the curvature along the direction orthogonal to the position change direction Y. Further, it is configured so that the first radius of curvature R1 is shorter than the second radius of curvature R2. In other words, the curve along the position change direction Y is tightly configured while making the whole curved surface shape.

As in this configuration, the display surface 41 has a first radius of curvature R1 and a second radius of curvature R2 to form a curved surface as a whole, so that the display surface 41 can easily follow the outer surface shape of the faucet body J1. Become. Therefore, when the display surface 41 is exposed to the window portion W provided on the first cover C1 of the faucet main body J1, the entire display surface 41 approaches the surface of the faucet main body J1 to improve visibility.

Further, by making the radii of curvature in the two directions different, and in particular, by shortening the first radius of curvature R1 in the position changing direction Y of the display surface 41, water can enter through the gap between the window portion W and the display surface 41. Even if this is the case, the water tends to flow to the edge 43 on the side of the display surface 41 along the position changing direction Y. In this regard, the point that the window portion W is inclined along the position change direction Y also contributes to some extent. Since the working portion 21 and the shaft portion 22a do not exist on the edge portion 43, dirt is prevented from accumulating on the shaft portion 22a and the like, and a good switching operation of the display body S is maintained for a long period of time. be able to.

The shape of the window portion W is also characterized in order to prevent water that has entered the inside of the first cover C1 from the window portion W from reaching the working portion 21 and the shaft portion 22a. In the present embodiment, the window portion W includes four opening edge portions W1. In this configuration, the window portion W is formed on the surface of the faucet main body J1, but is provided so as to be inclined so that the normal direction is slightly upward so that the user can easily see it. Assuming that the pair of opening edge portions W1 extending while intersecting the position changing direction Y of the display surface 41 is the opening edge portion W1, the position of the intersecting opening edge portion W10 located particularly downward is changed toward the center side. It is configured to spread outward along the direction Y.

With this configuration, for example, when water intrudes into the faucet main body J1 from the display surface 41, the intrusion position can be guided to the central portion of the lower crossing opening edge W10. That is, although the window portion W is formed on the surface of the faucet main body J1, it is often provided so as to be inclined so that the normal direction is slightly upward so that the user can easily see it. In that case, the central position of the lower crossing opening edge W10 is the lowest in the vertical direction. Even if water enters the inside of the faucet main body J1 from this position, the position is a position away from the working portion 21 and the shaft portion 22a. Therefore, the infiltrated water is prevented from adhering to the acting portion 21 and the shaft portion 22a, and the smooth movement of the display body S is maintained for a long period of time.

[Second Embodiment]
The structure of the display body 2 may be, for example, the one shown in FIG. Here, the working portion 21 and the shaft portion 22a are provided separately apart from each other, rather than being connected to the outer side in the axial direction of the working portion 21 to provide the shaft portion 22a. Further, the position of the acting portion 21 is provided so as to extend outward from the position of the shaft portion 22a. In order to secure the turning radius of the display main body 2, the leg portion 27 extends from the side portion of the display surface 41, and the shaft portion 22a is provided at the tip thereof. The working portion 21 projects from the base end portion of the leg portion 27. With this configuration, even if the water that has entered from the window portion W gets over the edge portion 43 of the display surface 41, the water is prevented from propagating thereafter by the acting portion 21, and there is little chance that the water will reach the shaft portion 22a. Become.

In the example of FIG. 7, only one acting portion 21 is formed, but in the sense that water reaching the shaft portion 22a is eliminated as much as possible, it is preferable to provide the acting portions 21 on both sides. At the end of the working portion 21, a spring receiving portion 24 for receiving the torsion spring 3 and a stopper 25 for the faucet main body J1 are provided.

[Third Embodiment]
As another embodiment of the water stop portion 5, the configuration shown in FIG. 8 may be used. That is, a rib 52 that protrudes toward the inner surface of the first cover C1 is provided along the edge portion 43 in which at least one of the action portion 21 and the shaft portion 22a is formed among the edge portions 43 of the display surface 41. You may. Here, an example in which the rib 52 is formed on the display board 4 mounted on the display main body 2 is shown, but the display board 4 may be formed integrally with the display main body 2.

The rib 52 narrows the gap between the first cover C1 and the inner surface and enhances the water stopping function. The width of the rib 52 along the axis direction of the shaft portion 22a is formed to be extremely narrow, and even if the rib 52 rubs against the inner surface of the first cover C1, the sliding resistance is small.

Further, since the display plate 4 has a small size as a component, providing such a rib 52 on the display plate 4 provides an inner convex portion 51 on the inner surface of the first cover C1 as shown in FIG. It is extremely easy and low cost compared to the installation. Therefore, with this configuration, the water stop portion 5 can be realized more rationally.

[Fourth Embodiment]
As another embodiment of the water stop portion 5, the configuration shown in FIG. 9 may be used. That is, a groove portion 53 retired from the display surface 41 is provided along the edge portion 43 in which at least one of the action portion 21 and the shaft portion 22a is formed among the edge portions 43 of the display surface 41.

By providing such a groove 53, the water to enter from the window W is held in the groove 53 and can be prevented from propagating to the shaft 22a and the like.

In FIG. 9, the heights of both display surfaces 41 sandwiching the groove 53 are equal, but in order to enhance the water blocking function, for example, the height of the display surface 41 outside the groove 53 is increased. You may leave it. That is, the water stopping function is further enhanced by providing the rib 52 in addition to the groove portion 53.

[Fifth Embodiment]
As another embodiment of the water stop portion 5, the configuration shown in FIG. 10 may be used. Here, a plurality of drainage ports 54 are provided at the bottom of the groove portion 53. Since it is preferable that the area of one drainage port 54 is large in order to enhance the drainage effect, it is preferable to form the drainage port 54 as long as possible along the edge portion 43.

Further, also in the case of the present embodiment, the rib 52 may be provided outside the groove 53. Further, the groove 53 and the rib 52 may not be provided, and a plurality of drainage ports 54 may be provided in the vicinity of the side portion of the display surface 41 having a single surface.

[Sixth Embodiment]
The shape of the display body 2 may be the one shown in FIG. Here, an example is shown in which the display body 2 and the display board 4 are integrally formed to form a display body S, and the display body S does not rotate but slides. With the slide structure in this way, the height dimension of the display body S can be significantly reduced, and depending on the shape of the first cover C1, it can be easily mounted inside.

For example, a stepped guide portion G is provided on both edge portions 43 of the display body S, and a rail portion is provided on the side of the faucet main body J1 although not shown. These are curved along the sliding direction. As a result, the display surface 41 can be exposed and retired without interfering with the window portion W.

At the end of the display body S, for example, two action portions 21b are provided. These action portions 21b are pressed by the two arm portions 12 of the operating body 1. In the case of the slide configuration, the movement of the display body S is more stable when the arms 12 are provided on both sides. Alternatively, although not shown, only one arm portion 12 may be provided at the center position in the width direction of the operating body 1 to press the center position of the display body S. In this case, the operation of the display body S is stable, and the configuration of the operation body 1 and the display body S can be simplified.

A spring 3a is provided between the display body S and the faucet body J1 at any position. As the spring 3a, for example, a coil spring is used. The length of the coil spring is slightly longer in order to secure the stroke of the display body S, but since it is arranged along the plane direction of the display body S, it is particularly suitable for storage inside the first cover C1. No problem arises.

As the water stop portion 5, FIG. 11 shows an example in which ribs 52 are provided on both edge portions 43. However, in addition to this, as described above, the groove portion 53 and the drainage port 54 may be provided or a combination thereof may be provided.

[Other Embodiments]
The above water stop portion 5 may be provided on the upper and lower edge portions 43 of the edge portion 43 of the display surface 41 facing the position change direction Y of the display main body 2. With such a configuration, it is possible to more reliably prevent the ingress of water from the window portion W.

Further, as the configuration of the water blocking portion 5, various configurations can be applied, such as providing a region having a rough surface roughness only on the edge portion 43 of the display surface 41, or attaching a felt member having both water absorption and antibacterial properties. be.

Further, as the material of each constituent member, an appropriate material can be selected as long as it can ensure ease of manufacture and durability. For example, as the material of the operating body 1, various metals, polyacetal resin (POM), ABS resin and the like can be used, and plating grade ABS resin is desirable from the viewpoint of cost, appearance and moldability. Further, as the material of the display body S, various metals, POM, ABS resin, etc. can be used, ABS resin is desirable from the viewpoint of cost, appearance, and moldability, and POM is desirable from the viewpoint of strength and durability. ..
