The water discharged to the water receiving portion 24 flows to the drainage hole 22. The water that has flowed to the drainage hole 22 is drained to the drainage flow path 28 connected to the sewer pipe.

  The handwasher 6 is embedded in the placement unit 12 such that the lower portion of the handwasher body 18 is inserted into the opening 30 installed in the placement unit 12. From this, compared with the case where the lower part of the hand-washing machine main body 18 is mounted on the upper surface of the mounting part 12, the amount which the hand-washing main body 18 protrudes upwards from the mounting part 12 can be reduced. Therefore, even when the counter 2 with a high height is installed, the user can easily use the hand-washing machine 6.

  The handwasher 6 is embedded in the opening 30 such that the overflow surface 32 is parallel to the horizontal plane. The “horizontal surface” in one embodiment of the present invention is a surface perpendicular to the direction in which gravity acts. As a result, even when clogging occurs in the drainage hole 22 or the drainage flow path 28, water can be stored up to the limit capacity of the handwasher 6, and overflow of water from the handwasher 6 can be suppressed as much as possible.

  The installation part 25 of the hand-washing machine main body 18 has the horizontal part 36 in which the faucet attachment hole 34 which the inside penetrated was installed, and the inclination part 38 provided continuously with the horizontal part 36.

FIG. 5A is a schematic cross-sectional view showing a state in which the screw 66 is screwed into the screwing portion 50. FIG. 5 (b) is a schematic cross-sectional view showing a state in which the screw 66 is further screwed to the screwing portion 50 as compared with the state shown in FIG. 5 (a).
Next, the supporting 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 handwasher body 18 has a support portion 40 that abuts on the placement portion 12. Further, a rubber bush mounting hole 44 into which the rubber bush 42 is inserted is installed below the handwasher body 18. In the embodiment of the present invention, the two rubber bush attachment holes 44 are installed in the hand-washing machine main body 18, but the invention is not limited thereto, and one rubber bush attachment hole 44 may be installed. Three or more rubber bush attachment holes 44 may be provided.

  As shown in FIGS. 5 (a) and 5 (b), the rubber bush 42 is engaged with a rubber bush main body 48 made of rubber and provided with a through hole 46 penetrating inside, and a metal screw. And a unit 50. The screwing portion 50 is screwed and provided on the inner wall surface of the through hole 46.

  The rubber bush main body portion 48 includes a first rubber bush main body portion 52, a second rubber bush main body portion 54, a third rubber bush main body portion 56, and a fourth rubber bush main body portion 58. The second rubber bush main body 54 is formed continuously to the first rubber bush main body 52. The third rubber bush main body portion 56 is formed continuously to the second rubber bush main body portion 54. The fourth rubber bush main body portion 58 is formed continuously to the third rubber bush main body portion 56. The outer diameters of the first rubber bush main body 52 and the third rubber bush main 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 portion 54 and the fourth rubber bush main body portion 58 are smaller than the inner diameter of the rubber bush mounting hole 44. The screwing 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 lateral 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 passes.

The supporting method of the hand-washing machine 6 and the fixing method to the counter 2 are demonstrated.

The load of the hand-washing machine 6 is supported by the support part 40 abutting on the upper surface of the mounting part 12.

  Next, the rubber bush 42 is inserted into the rubber bush mounting hole 44 of the handwasher body 18. The rubber bush 42 is inserted into the rubber bush attachment hole 44 from the fourth rubber bush main body 58. 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. Therefore, when inserting the rubber bush 42 into the rubber bush mounting hole 44, the third rubber bush main body portion 56 and the rubber bush mounting The holes 44 collide with each other. On the other hand, since the third rubber bush main body portion 56 is made of rubber, a worker or the like applies force to the rubber bush 42 in the direction of inserting the rubber bush 42 into the rubber bush 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 in 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 bush main body portion 56 collides with the rubber bush mounting hole 44 and is deformed so as to be crushed. As a result, a force acts on the handwasher body 18 in a direction approaching the bracket 60. Thus, the support portion 40 is in contact with the upper surface of the mounting portion 12 of the counter 2 with a strong force. Accordingly, the handwasher 6 is fixed to the counter 2.

  As shown in FIG. 4, a metal angle 68 is installed on the side wall 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. Thus, the lateral wall 102 can support the load of the mounting portion 12 of the counter 2.

It is set by experimental data calculated based on the parameters. Specifically, based on the experimental data, “the degree of satisfaction of the washing degree of the user's hand”, “the amount of water splashing out of the water receiving portion 24”, and “the hand washing position relative to the upper surface of the water receiving portion 24” Find out the height. And the dimension of the hand-washing machine 6 is determined by these three values.

The calculation method of the experimental data regarding the degree of satisfaction of the washing degree of the user's hand will be described.
Based on the experimental parameters described in FIG. 11, the user is asked to wash his hands. Users who wash their hands look at the hand-washing machine 6 used in the experiment, and evaluate the “lookability” in five steps. Moreover, the user who wash | cleaned the hand evaluates "comfortability of hand-washing" and "easiness of hand movement" in 5 steps, respectively. The average value of the evaluation values of "Ease of washing", "Comfort of hand washing", and "Ease of hand movement" is calculated, and the degree of satisfaction of the user's hand washing condition is 5 levels. Calculated by

A method of calculating experimental data regarding the amount of water splashing out of the water receiving portion 24 will be described.
A non-woven fabric is placed so as to surround the water receiver 24. At this time, the weight of the non-woven fabric to be installed is measured in advance.

  With the non-woven fabric placed around the water receiving portion 24, the user is allowed to wash his hands based on the experimental parameters described in FIG. The speed of the water discharged from the faucet device 20 at this time is 3 L / min. At this time, the user rubs the hand at a speed of about 250 times / minute for about 11 seconds. At this time, the insertion angle of the hand is about 23 degrees with respect to the horizontal. The third finger length of the user's hand is about 86 mm.

  After washing the user's hand, the weight of the non-woven fabric placed around the water receiver 24 is measured. From the difference between the weight of the nonwoven fabric before washing of the user's hand and the weight of the nonwoven fabric after washing, the amount of water splashing out of the water receiving portion 24 is calculated. Thus, based on the experimental parameters described in FIG. 11, the operation of calculating the amount of water splashing out of the water receiving portion 24 is performed three times each to calculate the average value of the amount of water splashing. The average value of the water repellant amount is taken as the amount of water repelled to the outside of the water receiving portion 24 in the experimental parameter at the time of measurement.

The calculation method of the experimental data regarding the height of the hand-washing position with respect to the upper surface of the water receiving part 24 is demonstrated. The height of the hand wash position with respect to the upper surface of the water receiving portion 24 is the vertical height from the upper surface of the water receiving portion 24 to the position P (see FIG. 10) of the base of the middle finger on the palm of the user.
Based on the experimental parameters described in FIG. 11, the user is asked to wash his hands. Take pictures of the hands being washed continuously at 20 images / sec for 3 seconds. A vertical height, ie, from the upper surface of the water receiving portion 24 to a position P (see FIG. 10) of the base of the middle finger in the palm of the user, from each of the obtained images.

It represents an average value of the height of the hand-washing position relative to the upper surface of the receiving portion 24.

  As the graph of FIG. 13B shows, the height of the hand wash position relative to the upper surface of the water receiving portion 24 decreases as the depth dimension of the water receiving portion 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 become substantially zero or less. That is, when the depth dimension of the water receiving portion 24 is 100 mm or more, a part of the user's hand is inserted into the water receiving portion 24. It is self-evident that when the user's hand is inserted into the water receiver 24, the amount of water splashing out of the water receiver 24 is reduced.

  In addition, according to the percentile value of males with larger hands than females in general, 95% of the length of Japanese males aged 7 to 99 is 200 mm or less. In addition, the definition of "hand length" is a linear distance from the wrist flexion line (the wrinkle closest to the palm) to the finger tip of the middle finger. Therefore, the depth dimension of the water receiving part 24 does not need the magnitude | size of 200 mm or more.

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