Japanese Patent Laid-Open No. 11-247248

 However, in order to commercialize a single lever mixing faucet when there is a wall in front of the user and the mixing faucet is stored in the wall, as shown in FIGS. 8 (a) and 8 (b), The cartridge 12 of the single lever mixing faucet 11 is placed horizontally in the interior 13 a of the wall 13, and the single lever 14 of the single lever mixing faucet 11 is provided so as to protrude from the through hole 15 of the wall 13 in the same direction as the cartridge 12. Is being considered.

  In this case, the ratio of hot water and water can be adjusted simply by rotating the single lever 14 left and right around its axis, and the amount of water can be adjusted by moving up and down. The adjusted water discharge is discharged from the faucet 16 to the bowl 10 of the vanity unit 9 via the pipe 17.

 However, there is a problem that it is not easy to obtain the necessary torque for rotating the single lever 14 left and right by the force of the finger, and the finger gets tired.

  Further, as shown in FIG. 9, even if the display unit 22 such as “low temperature” or “high temperature” is provided on the wall 13, there is a problem that the display is difficult to understand because the display is concentrated in a narrow place.

 For this reason, for example, if the user does not recognize that “hot water” is produced when the single lever 14 is rotated to the left, and “water” is produced when the single lever 14 is rotated to the right, or if the user is not used to it, it is serious. There was inconvenience. And it had to confirm whether it was "hot water" or "water" by actually discharging and touching water discharge directly.

  Further, when the amount of water is adjusted by operating the single lever 14 up and down, it is not known which position the operation position of the single lever 14 is. Therefore, the single lever 14 is actually moved up and down to visually check the water discharge. It was necessary to judge by contact.

<First Embodiment of the Present Invention>
Below, the 1st Embodiment of this invention is described based on FIGS. In addition, the same code | symbol is suitably attached | subjected and demonstrated to a part equivalent to the structure shown to Fig.8 (a), (b).

<Configuration of single lever mixing faucet>
As shown in FIGS. 1 (a) and 1 (b), the single lever mixing faucet 11 of the present invention has an inner wall 13 for pouring hot water and water into a bowl 10 of a vanity table 9, for example. It is a cartridge type single lever mixing faucet 11 stored in the.

  A cartridge 12 as a mixing faucet of the single lever mixing faucet 11 is installed vertically in the interior 13 a of the wall 13. A single lever 14 of the single lever mixing faucet 11 is provided so as to protrude from the through hole 15 of the wall 13 in a direction substantially perpendicular to the cartridge 12.

  And the single lever 14 is rotated right and left, the ratio of hot water and water is adjusted, and it can move up and down and can adjust the amount of water. The adjusted water discharge is discharged from the faucet 16 to the bowl 10 of the vanity unit 9 via the pipe 17.

  Further, a shielding plate 19 that shields the through hole 15 and is externally fitted to the single lever 14 is provided in the through hole 15 of the wall 13 so as to be slidable with respect to the wall 13.

  As shown in FIGS. 2A and 2B, a shielding plate 19 is fitted on the single lever 14 inside the wall 13 so as to be slidable with respect to the wall 13. It is held by a guide 20 fixed to the inner surface 13 b of the wall 13.

  The guide 20 is an angle member composed of a frame member 20a and a holding member 20b, and one end portion of the frame member 20a is fixed to the inner surface 13b of the wall 13 and is connected to the upper, lower, left and right so as to surround the shielding plate 19.

  Here, the attachment position of the frame member 20a, the gap Q of the inner surface 13b, and the lengths R1, R2 of the upper, lower, left, and right sides of the holding member 20b are determined so that the shielding plate 19 interlocking with the single lever 14 is always attached to the wall 13. It is set taking into consideration that it can be held slidably. In the figure, the maximum movement region of the shielding plate 19 is within the range of the length T1 in the horizontal direction and the length T2 in the vertical direction.

  As shown in FIGS. 3 (a) and 3 (b), the shielding plate 19 has a width T3 and a length T4, and the first neutral position S1 of the single lever 14 (the boundary position of hot water and water). For example, the left area M1 is displayed in a warm color (for example, red) and the right area M2 is displayed in a cool color (for example, light blue).

  And what the user can actually see from the outside of the wall 13 is the shielding plate 19 within the range seen through the through hole 15 of the wall 13.

  The material of the shielding plate 19 may be a resin or a metal that does not rust, such as stainless steel. However, in order to avoid contact wear during sliding, it is preferable that the display portion is dug from the surface to display a color.

<Operation of single lever mixer tap>
As shown in FIGS. 4 (a) and 5 (a), since the single lever 14 is at the upper limit position 15a at the left and right centers of the shielding plate 19 viewed through the through hole 15, the water discharge amount is in a fully open state, and It can be seen that the state is “water”. (In general, it may be considered water at the boundary between hot water and water.)
Here, when the shielding plate 19 is viewed from the front through the through hole 15, the position in the through hole 15 as the upper limit position of the single lever 14 and the position on the shielding plate 19 do not coincide with each other. An upper limit position (near) in the through hole 15 of the lever 14 is represented as an upper limit position 15 a of the single lever 14 on the shielding plate 19.

  It is preferable that the single lever 14 does not come into contact with the wall edge 13c around the through-hole 15 at any position so that an excessive force is not applied to the single lever 14 itself. The user himself / herself can easily determine the tactile sensation from the single lever 14 at the left / right / upper / lower limit positions of the single lever 14.

  4 (b) and 5 (b) show a state where the single lever 14 has moved from the state of FIGS. 4 (a) and 5 (a) to the right limit position 15b.

  At this position, since the single lever 14 is at the upper limit position 15a of the shielding plate 19 viewed through the through hole 15, the water discharge amount is in a fully open state, and the left region M1 of the shielding plate 19 viewed through the through hole 15 is more than the right region M2. Since it is wide, it can be seen that it is in a “hot water” state.

  Thus, even when the cartridge-type mixing faucet is stored inside the wall, the user visually determines the state of the shielding plate 19 through the through hole 15 of the wall 13 from the outside of the wall, and the single lever 14 It is easy to understand the operation position.

<Second Embodiment of the Present Invention>
Hereinafter, a second embodiment of the present invention will be described with reference to FIG. 6, but the same components as those in FIGS. 5A and 5B are denoted by the same reference numerals and redundant description is omitted. To do.

  As shown in FIG. 6A, the shielding plate 19 has a center point at the second neutral position S2 of the single lever 14 (a boundary position between hot water and normal temperature water and a water stop position). The upper line S3, the lower left oblique line S4, and the lower right oblique line S5 are respectively drawn from the left, “the left region M3 surrounded by the upper line S3 and the lower left oblique line S4”, and “the right surrounded by the upper line S3 and the lower right oblique line S5” For example, the left region M3 of the region M4 is displayed in a warm color and the right region M4 is displayed in a cool color.

  The “lower area M5 surrounded by the lower left oblique line S4 and the lower right oblique line S5” is displayed in black, for example, as a color that can be distinguished from the colors of the left area M3 and the right area M4.

  As shown in FIG. 6B, the position of the vertex S6 of the “lower region M5 surrounded by the lower left oblique line S4 and the lower right oblique line S5” of the shielding plate 19 viewed through the through hole 15 is in the vicinity of the upper limit position 15a. It turns out that the amount of water discharge is a full open state. The size of the “left region M3 surrounded by the upper line S3 and the lower left oblique line S4” and the “right region M4 surrounded by the upper line S3 and the lower right oblique line S5” of the shielding plate 19 viewed through the through hole 15 are the same. It can be seen that it is in a “water” state.

  FIG. 6C shows a state in which the single lever 14 has further moved from the state of FIG. 6B to the right limit position 15b.

  At this position, the amount of water discharged is fully open because the position of the vertex S6 of the “lower region M5 surrounded by the lower left oblique line S4 and the lower right oblique line S5” of the shielding plate 19 viewed through the through hole 15 is in the vicinity of the upper limit position 15a. I know that there is. Further, since the position of the vertex S6 is in the vicinity of the right limit position 15b, the “left region M3 surrounded by the upper line S3 and the lower left oblique line S4” of the shielding plate 19 viewed through the through hole 15 is “the upper line S3 and the lower right oblique line. Since it is wider (larger) than the right region M4 surrounded by S5, it is understood that the state is “hot water”.

  Although not shown, when the single lever 14 is lowered from the state shown in FIGS. 6B and 6C, the position of the vertex S6 of the “lower region M5 surrounded by the lower left oblique line S4 and the lower right oblique line S5” is lowered. Therefore, it is possible to visually determine that the water discharge amount is decreasing by looking at the change in the height position and the width of the lower region M5.

  Thus, when the cartridge-type mixing faucet is stored inside the wall, the user can visually determine the state of the shielding plate 19 from the outside through the through-hole 15 of the wall 13 from the outside of the wall. The 14 operation positions can be easily understood.

    As mentioned above, although embodiment of this invention was described based on drawing, all said Example showed an example of this invention, and it cannot be overemphasized that this invention should not be limited to these. Absent.

  The shielding plate 19 is externally fitted to the single lever 14, but may be slidably externally fitted. In this case, since the gap Q between the holding member 20b of the guide 20 on the top, bottom, left and right surrounding the shielding plate 19 and the inner surface 13b of the wall 13 can be narrowed, the shielding plate 19 can always be arranged at a position close to the inner surface 13b. It is possible to make the shielding plate easier to see for the user.

  Depending on the type of the single lever mixing faucet, if the single lever 14 is lowered, the amount of water discharge increases when the single lever 14 is lowered, and the arrangement of “hot water” and “water” may be opposite. What is necessary is just to carry out according to the situation.
