In the hand washing device, the water that has fallen into the pot may bounce off and scatter out of the pot.

The present invention has been made in view of such a situation, and an object of the present invention is to provide a hand washing device capable of suppressing the scattering of spouted water.

In order to solve the above problems, the hand washing device according to an embodiment of the present invention includes a pot portion, a water discharge device that discharges water toward the pot portion, and a drainage unit that drains the discharged water to the toilet bowl cleaning tank. .. The pot portion includes a pot portion main body and a connection portion connecting the pot portion main body and the drainage portion. The inner peripheral surface of the connecting portion has a water receiving surface located below the bottom surface of the pot portion main body and outside the upper end of the inner peripheral surface of the drainage portion. The pot portion and the water discharge device are configured so that the water discharged from the water discharge device falls on the water receiving surface.

It should be noted that any combination of the above components and those in which the components and expressions of the present invention are mutually replaced between methods, devices, systems and the like are also effective as aspects of the present invention.

According to the present invention, it is possible to provide a hand washing device capable of suppressing the scattering of spouted water.

It is a perspective view which shows the toilet bowl apparatus which the hand washing apparatus which concerns on embodiment is used. It is a block diagram which shows a part of the water supply system of the toilet bowl apparatus of FIG. 1 schematically. It is a top view of the hand washing apparatus of FIG. FIG. 3 is a cross-sectional view taken along the line AA of FIG. FIG. 3 is a cross-sectional view taken along the line BB of FIG.

Hereinafter, the same or equivalent components and members shown in the drawings shall be designated by the same reference numerals, and duplicate description thereof will be omitted as appropriate. Further, the dimensions of the members in each drawing are shown in an appropriately enlarged or reduced size for easy understanding. In addition, some of the members that are not important for explaining the embodiment in each drawing are omitted and displayed.

The process leading to the hand washing apparatus according to the embodiment will be described.
In the hand washing device, the water that has fallen into the pot may bounce off and scatter out of the pot, and it is required to prevent this. In straight water discharge, since the width of the discharged water is relatively narrow, most of the discharged water can be dropped to the drainage portion without dropping to the bottom of the pot portion. In this case, since it does not bounce off the pot, scattering is suppressed. In shower spouting, the width of the spouted water is relatively wide, so basically most of the spouted water cannot be dropped into the drainage section. If the width of the drainage part is increased according to the width of the water discharged by the shower spout, most of the water discharged can be dropped to the drainage part without dropping to the bottom of the pot part. If the width of the water is increased, the appearance of the hand-washing device is deteriorated, and a relatively large foreign substance may be mixed in the hand-washing device. From the above, the present inventors have obtained the invention according to the embodiment.

FIG. 1 is a perspective view showing a toilet bowl device 12 in which the hand washing device 10 according to the embodiment is used. The toilet bowl device 12 includes a toilet bowl 14, a casing 16, a toilet bowl washing tank (hereinafter, simply referred to as a tank) 18, and a hand washing device 10. The tank 18 stores washing water used for washing the toilet bowl (not shown) of the toilet bowl 14. The casing 16 accommodates the tank 18 and the like. The tank 18 and the casing 16 are placed on the toilet bowl 14. The hand washing device 10 is a so-called faucet device, and is attached to the casing 16 so as to close the opening 16a at the upper end of the casing 16.

FIG. 2 is a configuration diagram schematically showing a part of the water supply system of the toilet bowl device 12. The toilet device 12 includes a tank water supply channel 20, a branch water supply channel 22, and a ball tap 24. The hand washing device 10 includes a water discharge device 30.

The tank water supply channel 20 is a water channel for supplying water to the tank 18. A ball tap 24 is installed in the tank water supply channel 20. The ball tap 24 opens and closes the tank water supply channel 20 in conjunction with the water level in the tank 18. When the washing water in the tank 18 falls below a predetermined water level, the ball tap 24 opens and water is supplied into the tank 18 from the downstream end portion 20a of the tank water supply channel 20. When the washing water in the tank 18 reaches a predetermined water level or higher, the ball tap 24 closes and the water supply from the tank water supply channel 20 into the tank 18 is stopped.

The branch water supply channel 22 is a flow path that branches from the tank water supply channel 20 and is a water channel for supplying water to the water discharge device 30. The branch water supply channel 22 branches from the tank water supply channel 20 on the downstream side of the ball tap 24. Therefore, the water supply from the branch water supply channel 22 to the water discharge device 30 and its stop are also switched in conjunction with the water level of the tank 18.

FIG. 3 is a top view of the hand washing device 10. FIG. 4 is a cross-sectional view taken along the line AA of FIG. FIG. 5 is a cross-sectional view taken along the line BB of FIG. The hand washing device 10 further includes a hand washing device 26 and a water supply pipe 28. The water supply pipe 28 constitutes a part of the above-mentioned branch water supply channel 22. The water supply pipe 28 is arranged behind the pot portion 60 (described later) of the hand wash basin 26.

The hand wash basin 26 is made of synthetic resin, ceramics, or the like. The hand wash basin 26 includes a pot portion 60, a drainage portion 62, and an outer peripheral wall portion 64. The outer peripheral wall portion 64 extends downward from the upper end edge portion of the pot portion main body 66 (described later) so as to surround the pot portion 60 from the outer peripheral side. The drainage portion 62 is a cylindrical member extending vertically, and drains the water received by the pot portion 60 into the tank 18 (not shown in FIGS. 3 to 5).

The pot portion 60 receives water discharged from the water discharge device 30. The pot portion 60 includes a pot portion main body 66 and a connecting portion 68. The pot portion main body 66 mainly receives water dripping from the user's hand when washing hands and water whose momentum is weakened from the water discharge device 30 just before the end of water discharge.

The connection portion 68 connects the pot portion main body 66 and the drainage portion 62. The connecting portion 68 has an annular inner peripheral surface 68a. The inner peripheral surface 68a of the connecting portion 68 is continuous with the gently inclined bottom surface 66a of the pot portion main body 66 and the inner peripheral surface 62a of the drainage portion 62.

The connecting portion 68 is provided so that the entire inner peripheral surface 68a is located below the bottom surface 66a of the pot portion main body 66 and outside the upper end of the inner peripheral surface 62a of the drainage portion 62. The inner peripheral surface 68a of the connecting portion 68 is particularly smoothly inclined so as to be narrowed toward the upper end of the drainage portion 62 (that is, toward the lower side). That is, the inner peripheral surface 68a does not have a substantially horizontal portion. Further, the inner peripheral surface 68a of the connecting portion 68 has a steeper slope than the bottom surface 66a. Further, the connecting portion 68 has a horizontally long shape in a plan view (that is, when viewed from above) in accordance with a horizontally long water discharge as described later.

The front side portion 68b of the inner peripheral surface 68a of the connecting portion 68 has an inclination with respect to the horizontal plane equal to or greater than the inclination of the left and right side portions 68c and the rear side portion 68d, which are other parts of the inner peripheral surface 68a, with respect to the horizontal plane. It is composed. For example, the angle of the front side portion 68b of the inner peripheral surface 68a with respect to the horizontal plane may be 60 ° or more, and the angle of the left and right side portions 68c and the rear side portion 68d of the inner peripheral surface 68a with respect to the horizontal plane may be 30 ° to 60 °. In this case, the angle of incidence of the water discharged from the water discharge device 30 on the front portion 68 becomes relatively large.

The water discharge device 30 is attached to the upper part of the rear wall portion 66b of the pot portion main body 66. The water discharge device 30 (particularly, the plurality of water discharge ports 30a) is located behind the connection portion 68, and discharges water in a horizontally long shower shape toward the front. The plurality of spouts 30a all face the same direction so that the water discharged from the plurality of spouts 30a does not spread. In the present embodiment, the water discharge device 30 and the pot portion 60 are configured so that most of the water discharged from the water discharge device 30 falls on the front side portion 68b of the inner peripheral surface 68a of the connection portion 68.

In FIG. 4, the portion where the water discharged from the water discharge device 30 falls is shown by being surrounded by a dotted line. In the example of FIG. 4, most of the discharged water falls on the front side portion 68b of the inner peripheral surface 68a of the connecting portion 68, and a part of the discharged water falls on the left and right side portions 68c of the inner peripheral surface 68a. The other part of the spouted water has fallen directly into the drainage portion 62. That is, in the example of FIG. 4, the front side portion 68a and the left and right side portions 68c function as a water receiving surface for receiving the water discharged from the water discharge device 30. If the momentum of the water discharged from the water discharge device 30 is weak, such as when the pressure of the water supplied from the water supply pipe 28 is low, the water falls to a position lower than the dotted line in FIG. The entire circumference of 68a receives water.

The width of the annular upper end edge of the inner peripheral surface 68a of the connection portion 68 is larger than the width of the shower-like water discharged (at least the width of the water at the time of landing) so that most or all of the water discharged can be received. Is also getting bigger. In other words, when viewed in a plan view, the portion where water falls is surrounded by the upper end edge of the annular shape of the inner peripheral surface 68a of the connecting portion 68. On the other hand, the inner peripheral surface 68a of the drainage portion 62 is smaller than the width of the shower-like water discharged.

According to the hand washing device 10 according to the present embodiment described above, the water discharge device 30 and the pot portion 60 are configured such that the water discharged from the water discharge device 30 falls on the inner peripheral surface 68a of the connection portion 68. Further, the inner peripheral surface 68a is inclined so as to be narrowed as it goes down. Therefore, when the water discharged from the water discharge device 30 falls on the connection portion 68, the incident angle becomes relatively large. Therefore, when the water discharged from the water discharge device 30 falls into the pot portion 60, it is prevented from bouncing back to the pot portion and scattering.

Further, according to the hand washing device 10 according to the present embodiment, the width of the drainage section 62 can be made relatively small (for example, the same width as the conventional hand washing device 10) in order to suppress scattering by the connecting portion 68. Therefore, it is possible to maintain a good appearance and prevent large foreign substances from being mixed.

Further, according to the hand washing device 10 according to the present embodiment, the inner peripheral surface 68a of the connecting portion 68 is inclined so as to be narrowed toward the bottom. That is, the inner peripheral surface 68a of the connecting portion 68 does not have a substantially horizontal portion. Therefore, no water pool can be formed in the connection portion 68. When water falls into a puddle, the water bounces off relatively large, but according to the hand washing device 10 according to the present embodiment, this is suppressed.

The hand washing device according to the embodiment has been described above. It is understood by those skilled in the art that this embodiment is an example, and that various modifications are possible in the combination of the respective components, and that such modifications are also within the scope of the present invention.

(Modification 1)
In the embodiment, the case where the entire inner peripheral surface 68a of the connecting portion 68 is provided so as to be located below the bottom surface 66a of the pot portion main body 66 and outside the upper end of the inner peripheral surface 62a of the drainage portion 62. I explained, but it is not limited to this. For example, the connecting portion 68 may be provided so that only the front portion 68b of the inner peripheral surface 68a is located below the bottom surface 66a of the pot portion main body 66 and outside the upper end of the inner peripheral surface 62a of the drainage portion 62. ..

Further, in the connecting portion 68, the posterior portion 68d of the inner peripheral surface 68a is steeper with respect to the horizontal plane than the other portion of the inner peripheral surface 68a (that is, the front side portion 68b and the left and right side portions 68c of the inner peripheral surface 68a). It may be configured to be. Further, the connecting portion 68 is provided so that only the rear portion 68c of the inner peripheral surface 68a is located below the bottom surface 66a of the pot portion main body 66 and outside the upper end of the inner peripheral surface 62a of the drainage portion 62. May be good. In these cases, the water discharge device 30 and the pot portion 60 may be configured so that the water discharged from the water discharge device 30 is discharged toward the rear portion 68d of the inner peripheral surface 68a. That is, the rear portion 68d of the inner peripheral surface 68a may function as a water receiving surface.

Further, in the embodiment, the case where the inner peripheral surface 68a of the connecting portion 68 is smoothly inclined so as to be narrowed toward the bottom has been described, but the present invention is not limited to this. For example, the inner peripheral surface 68a may have a bent portion. For example, the shape of the inner peripheral surface 68a in the vertical cross section may be substantially L-shaped.

In summary, the inner peripheral surface 68a of the connection portion 68 is such that at least the portion where the water discharged from the water discharge device 30 directly falls is below the bottom surface 66a of the pot portion main body 66 and the inner peripheral surface of the drainage portion 62. It may be provided so as to be located outside the upper end of 62a. According to the hand-washing device according to the present modification, the same action and effect as those played by the hand-washing device 10 according to the embodiment are exhibited.

(Modification 2)
In the embodiment, the case where the water discharge device 30 discharges water from the shower has been described, but the present invention is not limited to this. For example, the water discharge device 30 may be configured to discharge straight water instead of shower water. Further, the water discharge device 30 may be configured to be able to switch between shower water discharge and straight water discharge.

Further, for example, the water discharge device 30 may be configured to discharge water in a wide and continuous waterfall shape instead of shower water discharge. In this case, the spout 30a may be formed in a slit shape so as to spout water in a waterfall shape.

The present invention has been described above based on the embodiments. It will be appreciated by those skilled in the art that this embodiment is exemplary and that various modifications and modifications are possible within the claims of the invention and that such modifications and modifications are also within the claims of the present invention. Where is it? Therefore, the descriptions and drawings herein should be treated as exemplary rather than limiting.

From the above description, the following inventions are recognized.
The hand washing device of one aspect of the present invention includes a pot portion, a water discharge device that discharges water toward the pot portion, and a drainage unit that drains the discharged water to the toilet bowl cleaning tank. The pot portion includes a pot portion main body and a connection portion connecting the pot portion main body and the drainage portion. The inner peripheral surface of the connecting portion has a water receiving surface located below the bottom surface of the pot portion main body and outside the upper end of the inner peripheral surface of the drainage portion. The pot portion and the water discharge device are configured so that the water discharged from the water discharge device falls on the water receiving surface.

According to this aspect, the water receiving surface that receives the water discharged from the water discharge device is located below the bottom surface of the pot portion main body and outside the upper end of the inner peripheral surface of the drainage portion. Therefore, even if the water that has fallen on the water receiving surface splashes, it is prevented from scattering beyond the water receiving surface to the bottom surface of the pot portion main body or to the outside of the pot portion main body. Further, since water is received on the water receiving surface, the width of the drainage portion can be made relatively small (for example, to the same extent as a conventional hand washing device), and a good appearance as a hand washing device can be maintained.

The entire inner peripheral surface of the connecting portion may be located below the bottom surface of the pot portion main body and outside the upper end edge of the inner peripheral surface of the drainage portion. In this case, the scattering of water can be further suppressed.

The water receiving surface may be an inclined surface continuous with the pot body and the upper end edge. In this case, since a puddle cannot be formed in the portion where the water lands, the scattering of the water can be further suppressed.

The water receiving surface includes a front portion of the inner peripheral surface of the connection portion, and the water discharge device may be located behind the connection portion.

The inner peripheral surface of the connection portion may be inclined so as to be narrowed as a whole as it goes down. In this case, since no water pool can be formed on the inner peripheral surface of the connection portion, the scattering of water can be further suppressed.

The water receiving surface includes a front side portion of the inner peripheral surface of the connecting portion, and the front side portion may be steeper with respect to a horizontal plane than other portions of the inner peripheral surface of the connecting portion. In this case, since the angle at which the water is incident on the front side portion of the inner peripheral surface of the connecting portion is relatively large, it is particularly prevented that the water that has fallen on the water receiving surface splashes toward the front side of the pot portion. As a result, the scattering of water can be further suppressed.
