Next, the support method of the hand-washing machine 6 which concerns on one Embodiment of this invention, and the fixing method to the counter 2 are demonstrated using FIG. 4 and 5. FIG.

  As shown in FIGS. 4 and 5, the hand-washer body 18 includes a support portion 40 that abuts the placement portion 12. A rubber bushing mounting hole 44 into which the rubber bushing 42 is inserted is installed below the hand-washer body 18. In the embodiment of the present invention, the two rubber bush mounting holes 44 are installed in the hand-washing machine main body 18, but not limited thereto, one rubber bush mounting hole 44 may be installed, Three or more rubber bush mounting holes 44 may be provided.

  As shown in FIGS. 5 (a) and 5 (b), the rubber bush 42 includes a rubber-made rubber bush main body 48 in which a through-hole 46 through which the inside passes is installed, and a metal screw-fit. Part 50. The threaded portion 50 is threaded and is provided on the inner wall surface of the through hole 46.

  The rubber bush main body 48 includes a first rubber bush main body 52, a second rubber bush main body 54, a third rubber bush main body 56, and a fourth rubber bush main body 58. The second rubber bush main body 54 is formed continuously with the first rubber bush main body 52. The third rubber bush main body portion 56 is formed continuously with the second rubber bush main body portion 54. The fourth rubber bush main body 58 is formed continuously with the third rubber bush main body 56. The outer diameters of the first rubber bush body 52 and the third rubber bush body 56 are larger than the inner diameter of the rubber bush mounting hole 44. The outer diameters of the second rubber bush main body 54 and the fourth rubber bush main body 58 are smaller than the inner diameter of the rubber bush mounting hole 44. The threaded portion 50 is provided on the inner wall surface of the through hole 46 formed inside the fourth rubber bush main body portion 58.

  A metal bracket 60 is installed on the horizontal wall surface 102 of the toilet room 100. The bracket 60 has a flange portion 62 formed in an L shape. The flange portion 62 is provided with a screw insertion hole 64 through which the inside penetrates.

The support method of the hand-washing machine 6 and the fixing method to the counter 2 are demonstrated.
First, the lower part of the hand-washer body 18 is inserted into the opening 30 of the placement part 12. As a result, the hand washer 6 is embedded in the placement unit 12. And the support part 40 of the hand-washing machine main body 18 contact | abuts on the upper surface of the mounting part 12 of the counter 2. As shown in FIG. The load of the hand-washing machine 6 is supported by the support part 40 contacting the upper surface of the mounting part 12.

  Next, the rubber bush 42 is inserted into the rubber bush mounting hole 44 of the hand-washing machine body 18. The rubber bush 42 is inserted from the fourth rubber bush main body 58 into the rubber bush mounting hole 44. Since the outer diameter of the third rubber bush main body portion 56 is larger than the inner diameter of the rubber bush mounting hole 44, when the rubber bush 42 is inserted into the rubber bush mounting hole 44, the third rubber bush main body portion 56 and the rubber bush mounting portion are attached. The hole 44 collides. On the other hand, since the third rubber bushing main body portion 56 is made of rubber, an operator or the like applies a force to the rubber bushing 42 in the direction of inserting the rubber bushing 42 into the rubber bushing mounting hole 44. The rubber bush 42 can be inserted into the rubber bush mounting hole 44 until the rubber bush mounting hole 44 and the first rubber bush main body 52 come into contact with each other.

  Next, a metal screw 66 is inserted into the screw insertion hole 64 of the flange portion 62. The screw 66 inserted through the screw insertion hole 64 is inserted into the through hole 46 of the rubber bush main body 48. The screw 66 inserted into the through hole 46 is screwed into the screwing portion 50.

  As shown in FIG. 5A, as the screw 66 is screwed into the screwing portion 50, a force acts on the third rubber bush main body portion 56 downward, that is, in a direction approaching the bracket 60. As a result, as shown in FIG. 5B, the third rubber bushing main body portion 56 collides with the rubber bushing mounting hole 44 and deforms so as to be crushed. As a result, a force acts on the handwasher body 18 in a direction approaching the bracket 60. Therefore, the support portion 40 is brought into contact with the upper surface of the placement portion 12 of the counter 2 with a strong force. Accordingly, the hand washing machine 6 is fixed to the counter 2.

  As shown in FIG. 4, a metal angle 68 is installed on the lateral wall surface 102 of the toilet room 100. The upper end portion 70 of the angle 68 supports the mounting portion 12 of the counter 2 from below. As a result, the load on the mounting portion 12 of the counter 2 can be supported by the lateral wall surface 102.

The hand-washing machine main body 18 which concerns on one Embodiment of this invention is further demonstrated using FIGS.

  As shown in FIG. 6A, the upper surface 36 a of the horizontal portion 36 protrudes upward from the upper surface 38 a of the inclined portion 38. That is, the upper surface 36 a of the horizontal portion 36 is projected from the upper surface of the installation portion 25. In other words, the upper surface 36 a of the horizontal portion 36 is located above the upper surface 38 a of the inclined portion 38. Further, the lower surface 36 b of the horizontal portion 36 is recessed upward from the lower surface 38 b of the inclined portion 38. That is, the lower surface 36 b of the horizontal portion 36 is recessed from the lower surface of the installation portion 25. In other words, the lower surface 36 b of the horizontal portion 36 is located above the lower surface 38 b of the inclined portion 38. Accordingly, when the faucet device 20 is attached to the horizontal portion 36 using the nut 39, the convex shape of the upper surface 36a of the horizontal portion 36 and the concave shape of the lower surface 36b of the horizontal portion 36 are It becomes a mark of the mounting position. Therefore, the faucet device 20 can be easily attached to the hand-washer main body 18 by the convex shape of the upper surface 36 a of the horizontal portion 36 and the concave shape of the lower surface 36 b of the horizontal portion 36.

  The thickness of the horizontal part 36 and the inclined part 38 is uniform. That is, the thickness (thickness) C of the horizontal portion 36 is the same as the thickness (thickness) D of the inclined portion 38. This can prevent wrinkles and cracks from occurring in the hand-washing machine body 18 when the hand-washing machine body 18, which is pottery, is baked and produced. In the embodiment of the present invention, the thickness C of the horizontal portion 36 is the same as the thickness D of the inclined portion 38, but is not limited thereto, and the thickness C of the horizontal portion 36 and the thickness of the inclined portion 38 are not limited thereto. The difference with thickness D should just be less than 5 millimeters (mm), for example.

  As shown in FIG. 6B, the horizontal portion 36 is formed smoothly and continuously with the inclined portion 38. Note that “smooth” in one embodiment of the present invention refers to a state where there are no protrusions such as burrs on the surface. This improves the cleanability of the connection portion between the horizontal portion 36 and the inclined portion 38.

  As shown in FIG. 7, the inclined portion 38 is inclined toward the water receiving portion 24 at an angle θ with respect to the horizontal portion 36. The magnitude of θ is, for example, 1.5 to 2 degrees. As a result, water droplets or the like applied to the inclined portion 38 can be caused to flow to the water receiving portion 24 by gravity. Therefore, it is possible to suppress the accumulation of water in the inclined portion 38.

  As shown in FIG. 8, the upper surface 36 a of the horizontal portion 36 is formed so as to cover the periphery of the attachment portion 29 and to extend from the attachment portion 29 to the end portion 72 of the hand-washer body 18 as viewed from above. Yes. As a result, on the upper surface 36a of the horizontal portion 36, there is no depression between the attachment portion 29 and the end portion 72 when viewed from above. Therefore, the cleanability of the handwasher body 18 is improved.

FIG. 9 is a schematic top view showing a hand-washing machine body according to another embodiment of the present invention.
As shown in FIG. 9, the upper surface 36a of the horizontal portion 36 is formed in the same shape as the shape of the attachment portion 29 as viewed from above. As a result, the area of the horizontal portion 36 can be minimized, and the cleanability of the upper surface of the handwasher body 18 is improved.

FIG. 10 is a schematic view showing an example of use of the hand washing machine according to one embodiment of the present invention.
FIG. 11 is a graph relating to the vertical distance between the upper surface of the water receiving portion and the water discharge hole according to the embodiment of the present invention.
FIG. 12 is a graph relating to the depth dimension of the water receiving portion according to the embodiment of the present invention.
FIG. 10 is a schematic cross-sectional view taken along the cutting plane A1-A1 shown in FIG. The graphs shown in FIGS. 11 and 12 are graphs calculated from the obtained experimental data based on the statistical idea of experimental design.
The dimension setting of the hand-washing machine 6 which concerns on one Embodiment of this invention is further demonstrated using FIGS.

  As shown in FIG. 10, the depth dimension E of the hand-washing machine main body 18 which concerns on one Embodiment of this invention is 200 mm or less, for example. The vertical distance F between the upper surface of the water receiver 24 and the lowermost end of the water discharge hole 26 is, for example, 50 mm or more and 100 mm or less. The “upper surface of the water receiving portion 24” is synonymous with the overflow surface 32 of the hand-washing machine body 18. The depth dimension G of the water receiving part 24 is, for example, 100 mm or more and 200 mm or less. In the hand-washing machine 6 having such a dimension setting, the user naturally inserts a certain amount of hands into the water receiving portion 24 when washing the hands. As a result, the occurrence of water splashing to the outside of the water receiving portion 24 can be suppressed.

  The horizontal axis of the graph shown in FIG. 11A is the vertical distance F between the upper surface of the water receiving portion 24 and the lowermost end of the water discharge hole 26, that is, the height of the water discharge hole 26. The vertical axis of the graph shown in FIG. 11A represents the satisfaction degree of the user's hand cleaning condition. As for the satisfaction level of the user's hand, the satisfaction level “5” is “very easy to wash”, the satisfaction level “4” is “easy to wash”, and the satisfaction level “3” is “normal wash”. “Easy”, Satisfaction “2” is “Difficult to wash”, Satisfaction “1” is “Very difficult to wash”.

  As the graph of FIG. 11A shows, the higher the water discharge hole 26 is, the easier the user feels to wash his hands. If the height of the water discharge hole 26 is 50 mm or more, the satisfaction level of the user's hand cleaning condition is substantially “3”. That is, when the height of the water discharge hole 26 is 50 mm or more, the user feels that it is easy to wash in a normal manner in the hand washing operation.

  The horizontal axis of the graph shown in FIG. 11B is the distance between the upper surface of the water receiving portion 24 and the lowermost end of the water discharge hole 26, that is, the height of the water discharge hole 26. The vertical axis of the graph shown in FIG. 11B is the amount of water splashing out of the water receiving portion 24.

  As shown in the graph of FIG. 11B, the higher the height of the water discharge hole 26, the greater the amount of water splashing out of the water receiving portion 24. If the height of the water discharge hole 26 is 100 mm or less, the amount of water splashing to the outside of the water receiving portion 24 is the amount of water splashing to the outside of the water receiving portion 24 when the height of the water discharge hole 26 is 150 mm. Less than half of the amount. That is, if the height of the water discharge hole 26 is 100 mm or less, the amount of water splashing to the outside of the water receiving portion 24 is greatly reduced.

  Further, the height of the water discharge hole 26, that is, the vertical distance F between the upper surface of the water receiving portion 24 and the lowermost end of the water discharge hole 26 is set to 50 mm or more by the water supply law.

  From the above, the vertical distance F between the upper surface of the water receiving portion 24 and the lowermost end of the water discharge hole 26 is preferably 50 mm or more and 100 mm or less.

  The horizontal axis of the graph shown in FIG. 12A is the depth dimension G of the water receiving portion 24. The vertical axis of the graph shown in FIG. 12A is the satisfaction level of the user's hand cleaning condition. As for the satisfaction level of the user's hand, the satisfaction level “5” is “very easy to wash”, the satisfaction level “4” is “easy to wash”, and the satisfaction level “3” is the same as before. “Normal washability”, satisfaction “2” is “hard to wash”, and satisfaction “1” is “very hard to wash”.

  As the graph of FIG. 12A shows, the greater the depth dimension G of the water receiving portion 24, the easier the user feels to wash their hands. If the depth dimension G of the water receiving part 24 is 70 mm or more, the satisfaction degree of the user's hand cleaning condition is “3” or more. That is, when the depth dimension G of the water receiving portion 24 is 70 mm or more, the user feels that the washing is easier than usual in the hand washing operation.

  The horizontal axis of the graph shown in FIG. 12B is the depth dimension G of the water receiving portion 24. The vertical axis of the graph shown in FIG. 12B is the height of the hand washing position with respect to the upper surface of the water receiver 24. In addition, the height of the hand-washing position with respect to the upper surface of the water receiving part 24 is a vertical height from the upper surface of the water receiving part 24 to the position P of the base of the middle finger in the palm of the user (see FIG. 10). When the height of the hand-washing position with respect to the upper surface of the water receiving portion 24 is a positive value, the position P exists above the upper surface of the water receiving portion 24. When the height of the hand-washing position with respect to the upper surface of the water receiving portion 24 is a negative value, the position P exists below the upper surface of the water receiving portion 24.

  As shown in the graph of FIG. 12B, the height of the hand-washing position with respect to the upper surface of the water receiver 24 decreases as the depth dimension of the water receiver 24 increases. If the depth dimension of the water receiving part 24 is 100 mm or more, the height of the hand-washing position with respect to the upper surface of the water receiving part 24 will be substantially zero or less. That is, if the depth dimension of the water receiving part 24 is 100 mm or more, a part of the user's hand is inserted into the water receiving part 24. Obviously, when a part of the user's hand is inserted into the water receiving portion 24, the amount of water splashing to the outside of the water receiving portion 24 decreases.

  In general, according to the percentile value of men with larger hands than women, the length of Japanese men from the age of 7 to 99 is 95% less than 200 mm. Note that the definition of “hand length” is a linear distance from the wrist bending line (the wrinkle closest to the palm) to the fingertip point of the middle finger. Therefore, the depth dimension of the water receiving part 24 does not need to be 200 mm or more.

  From the above, it is preferable that the depth dimension of the water receiving portion 24 is 100 mm or more and 200 mm or less.
