JP 2009-257075 A

If the above-mentioned faucet is used, it is possible to prevent water from flowing from the shower spout to the faucet body. However, since there is a water-preventing projection, water discharged from the sprinkling holes is directed toward the water-preventing projection. There is a concern that unintentional water discharge may occur toward the faucet body side by being pulled, and the faucet body and its surroundings may be wetted.
More specifically, when water discharge is started or when the amount of water discharge is increased by adjusting the flow rate, etc., the water that has been transferred from the water transfer prevention protrusion gradually increases in the direction when water is discharged correctly from the water spray hole. However, if the surface tension of water is maintained in the balance between the speed of displacement and the surface tension of water, the water sprinkling hole and the water transport preventing protrusion are between the water transmission preventing protrusion and the water sprinkling hole. There is a possibility that a substantially triangular water film having the apex at the root of the water and the tip of the water transfer prevention protrusion may occur. When a water film is formed, the stream line of water discharged from the sprinkling holes is pulled by the water film and the water transfer prevention protrusion, and water is discharged along the water film toward the tip of the water transfer prevention protrusion. Then, the water discharged reaching the tip of the water transfer prevention protrusion is discharged at an angle along the water film as it is beyond the tip of the water transfer prevention protrusion.
Since the water transfer prevention protrusion is arranged on the faucet body side from the water spray hole, when water is discharged at an angle along the water film, water is discharged toward the water faucet body. It will wet the surroundings.

  The present invention has been made to solve the above problems, and provides a faucet that does not wet the faucet body and its surroundings by unintentional water discharge directed toward the faucet body as described above.

In order to achieve the above object, according to the first aspect of the present invention, a base end portion that is fixed to the mounting surface, a support portion that stands above the base end portion and is inclined obliquely upward, and A water faucet connected to the front end and inclined upward in accordance with the inclination of the support portion, wherein the water discharge portion has a shower spout having a plurality of water spray holes having a small hole diameter. And a water transfer prevention protrusion having a shape protruding in the water discharge direction of the faucet on the base end side of the shower water discharge port, and water between the water transfer prevention protrusion and the watering hole on the lower side. A water film formation preventing portion that prevents the film from being formed, and the water film formation preventing portion is a protrusion protruding in a convex shape from a surface between the water spray hole and the water transfer prevention protrusion, and the protrusion The protrusion height of the water is from the upper watering hole to the tip of the water transfer prevention protrusion. And wherein the lower the virtual line Cow.
This prevents the formation of a water film between the water transmission prevention protrusion and the water spray hole that occurs when water discharge is started or when the water discharge amount is increased by adjusting the flow rate, etc. It is possible to prevent the water faucet body and its surroundings from getting wet by being pulled toward the protrusion and causing unintended water discharge toward the faucet body side.

Further, it is possible that the flow can be downstream of the flow of the water film forming prevention unit that has issued collision acts to peel the water flow from the water discharge unit surface, to reliably prevent the water film formation. Furthermore, since the protrusion height of the protrusion that is the water film formation prevention part is lower than the protrusion height of the water transfer prevention protrusion, water discharge from the water spray hole is caused by the water film formation prevention part as in the phenomenon that occurs in the water transfer prevention protrusion. Even when unintentional water discharge occurs toward the faucet body by being pulled by a certain protrusion, it is possible to prevent the water transfer prevention protrusion from blocking the water discharge and wetting the faucet body and its surroundings.

Further, according to the second aspect of the invention, before Kisuimaku formation prevention protrusion and water Tsutai prevention projection it was characterized in that it is provided integrally with the shower spout.
As a result, the water film formation preventing portion and the water transfer preventing protrusion can be formed at a low cost, and the gaps between parts generated when the water film formation preventing portion and the water transfer preventing protrusion are configured separately can be eliminated, and these can be configured hygienically. Can do.

  Provided is a faucet that does not wet the faucet body and its surroundings due to unintended water discharge directed toward the faucet body.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, in each drawing, the same code | symbol is attached | subjected to the same component and detailed description is abbreviate | omitted suitably.
FIG. 1 is a schematic perspective view of a water faucet in the first embodiment of the present invention. As shown in FIG. 1, the faucet 10 according to the first embodiment of the present invention is a so-called single lever mixing faucet that operates to adjust the water discharge temperature, water discharge, and water discharge amount with a single operation lever 102. The configuration mainly includes a faucet body 101 that constitutes a single lever mixing tap, a spout 103 that stands up above the faucet body and is inclined obliquely upward, and a water discharger 104 that is connected to the spout 103. .

  The faucet body 101 is connected to a water and hot water supply facility and has a single valve.

  The spout 103 is rotatably attached to the faucet body 101, stands up above the faucet body 101, and tilts obliquely upward. The inside of the spout 103 is hollow, and the inside can pass water.

  The water discharger 104 is mounted coaxially with the spout 103 while maintaining an inclination angle, and the inside can pass water.

  FIG. 2 is a schematic perspective view illustrating an installation state of the faucet in the system kitchen according to the first embodiment of the present invention. The system kitchen 30 includes a sink 301 and a counter 302. Further, the system kitchen 30 may include a cooking table (not shown) extending to at least one of the left side and the right side of the counter 302.

  The faucet 10 is installed on the counter upper surface 303 on the back side of the sink 301 as viewed from the user, that is, behind the system kitchen 30. The faucet body 101 of the faucet 10, that is, a portion in the vicinity attached to the counter 302 is provided to be perpendicular to the counter upper surface 303. The spout 103 positioned above a predetermined dimension is provided to be inclined with respect to the counter upper surface 303. In this case, the inclination angle θ can be set to about 40 ° with respect to the counter upper surface 303, for example. The water discharger 104 is coaxially connected to the inclined spout 103 while maintaining the inclination angle. The water discharger is provided with a shower water discharge port 105 toward the sink 301. That is, the shower spout 105 is inclined about 40 degrees with respect to the counter upper surface 303 and is provided toward the sink. Therefore, a water discharge flow is discharged from the shower water discharge port 105 to the sink 301 in a direction inclined with respect to the counter upper surface 303. Further, below the shower spout 105, a water transfer preventing protrusion 106 is provided above the sink 301. For this reason, when a small amount of water is discharged from the shower outlet 105, the water flow (water transfer) that flows down the surface of the water discharge unit 104 can be transferred from the water transfer prevention protrusion 106 to the sink 301, and the water flow is transferred to the faucet body 101. It can be prevented from happening.

FIG. 3 is a schematic view for illustrating the water discharge part of the faucet according to the first embodiment of the present invention, and FIG. 4 is a side sectional view of the water discharge part of the water faucet according to the first embodiment of the present invention.
The water discharger 104 includes a shower water discharge port 105 in which a plurality of water spray holes 110 having a small hole diameter are formed, and a water discharge prevention projection 106 below the shower water discharge port 105, and water discharge between the shower water discharge port 105 and the water transfer prevention protrusion 106. A water film formation preventing unit 107 is provided on the surface of the unit 104. The inside of the water discharger 104 is hollow and constitutes a water passage 108 that guides the water supplied from the spout 103 to the shower spout 105.

  In the faucet 10 shown in FIGS. 1 to 4, a water transfer prevention protrusion 106 protruding in a substantially vertical direction with respect to the surface of the water discharge portion 104 is provided at the lower portion of the shower water discharge port 105. The water transfer prevention protrusion 106 is provided integrally with the water discharger. The lower surface 106a of the water transfer prevention protrusion extends and protrudes in the shower water discharge direction. When the water discharge portion 104 is connected to the spout 103, the tip 106b of the water transfer prevention protrusion faces the gravitational direction side with respect to the horizontal plane. It is inclined to. For this reason, when a small amount of water is discharged, the water that travels on the surface of the water discharge portion flows down from the tip 106b, and water transfer below the tip 106b can be prevented.

  In the faucet 10 shown in FIGS. 1 to 4, a water film formation preventing portion 107 is provided between the shower water outlet 105 and the water transfer preventing protrusion 106. The faucet water film formation preventing portion 107 according to the first embodiment of the present invention is a protruding portion 107a in which a part of the surface of the water discharging portion 104 is raised in a convex shape, and the protruding height H107a of the protruding portion 107a is the water It is lower than the protrusion height H106 of the transmission preventing protrusion 106.

  5 (a) to 5 (d) show that when the water faucet 10 starts discharging water or when a small amount of water is discharged by adjusting the flow rate or the like, the amount of water discharged increases and the water flow 900 is discharged correctly from the sprinkling hole 106. It is a schematic diagram which shows the water discharging state until it displaces in the direction when it was done. FIG. 5A shows a state in which a small amount of water is being discharged when the faucet 10 starts water discharge or by adjusting the flow rate, and FIG. 5D shows that the water discharge amount increases and the water flow 900 is correctly discharged from the water spray hole 106. FIG. 5 (b) and FIG. 5 (c) show the displacement process, and the water discharge amount is as shown in FIG. 5 (a) <FIG. 5 (b) <FIG. 5 (c) <FIG. 5 (d). is there. In the faucet 10, when a small amount of water is discharged when water discharge is started or when the flow rate is adjusted, the water flow 900 passes along the surface of the water film formation prevention unit 107 and is transferred from the water transfer prevention protrusion 106. A state is reached (FIG. 5A). When the water discharge amount is increased from there, the flow rate of the water flow 900 that flows down the surface of the water discharge portion increases, and when the water flow 900 gets over the water film formation prevention portion 107, the protrusion 107a of the water film formation prevention portion 107 A flow 901 in a direction away from the water discharger surface is generated downstream (FIG. 5B). As the amount of water discharged increases, the water flow 900 gradually displaces in the direction when water is properly discharged from the sprinkling holes 110. On the other hand, the flow 901 away from the surface of the water discharger portion also becomes strong, and when the action becomes larger than the surface tension of the water discharger surface 104a, the water flow 900 is peeled off from the water discharge surface 104a (FIG. 5C), and further the flow rate. When the water flow increases, the water flow 900 is completely displaced in the direction when water is properly discharged from the water spray hole 110 (FIG. 5D). Here, when the water film formation prevention unit 107 is not provided, when the water discharge is started or when the water discharge amount is increased by adjusting the flow rate, the water spray holes, the root of the water transfer prevention protrusion, and the water transfer prevention are generated. A substantially triangular water film with the tip of the protrusion as the apex is not formed, that is, the formation of a water film can be prevented, and the water discharged from the sprinkling holes is pulled toward the water transfer prevention protrusion, so that the faucet body side It is possible to prevent unintended water discharge toward the water and wet the faucet body and its surroundings.

  FIG. 5 (e) shows a process of shifting from the state shown in FIG. 5 (c) to the state shown in FIG. 5 (d). It is a schematic diagram of the state pulled by a certain projection. In this case, the protrusion height H107a of the protrusion 107a, which is the water film formation prevention portion, is lower than the imaginary line from the water spray hole 110 toward the tip of the water transfer prevention protrusion 106, and therefore the water film formation prevention portion 107 is pulled. The discharged water collides with the water transfer prevention protrusion 106 and is in a state of being transferred from the water transfer prevention protrusion 106. This prevents the faucet body and its surroundings from getting wet even when the water discharged from the sprinkling holes is pulled by the protrusion that is the water film formation preventing part, as in the phenomenon that occurs in the water transfer prevention protrusion. .

  FIG. 6 is a schematic view for illustrating a water discharge part of a faucet according to the second embodiment of the present invention, and FIG. 7 is a side sectional view of the water discharge part of the water faucet according to the second embodiment of the present invention. As shown in FIGS. 6 and 7, the faucet 20 in the second embodiment of the present invention is different from the first embodiment in that the water film formation preventing portion is provided on the surface between the shower spout 105 and the water transfer preventing protrusion 106. A depressed portion 107b having a concave portion is formed.

FIGS. 8A to 8D show that when the water faucet 20 starts water discharge or when a small amount of water is discharged by adjusting the flow rate, the water discharge amount increases, and the water flow 900 is correctly discharged from the sprinkling hole 110. It is a schematic diagram which shows the state until it displaces in the direction when it was done. FIG. 8A shows a state in which a small amount of water is discharged at the faucet 20 when water discharge is started or when the flow rate is adjusted, and FIG. FIG. 8 (b) and FIG. 8 (c) show the displacement process, and the amount of water discharge is shown in FIG. 8 (a) <FIG. 8 (b) <FIG. 8 (c) <FIG. 8 (d). is there. When a small amount of water is discharged at the faucet 20 when water discharge is started or when the flow rate is adjusted, the water flow 900 passes through the surface of the depressed portion 107b, which is a water film formation prevention portion, and passes through the water prevention protrusion. It will be in the state which passes down from 106 (Fig.8 (a)). From there, the amount of water discharged is increased, and when the flow rate of the water flow 900 flowing down the surface of the water discharge portion increases and the thickness of the water flow 900 increases, it passes through the depressed portion 107b which is a water film formation prevention portion. Stream 902 is generated. The water flow 902 is away from the surface of the depression 107b. (FIG. 8B). As the amount of water discharged increases, the flow 902 passing through the depressed portion 107b also becomes stronger, and when the function becomes larger than the surface tension of the depressed portion 107b, the water flow 900 is peeled off from the depressed portion 107b (FIG. 8C). When the flow rate further increases, the water flow 900 is displaced in the direction when water is properly discharged from the sprinkling hole 110 (FIG. 8D). Also in this case, when the water film formation prevention unit 107 is not provided, when the water discharge is started or when the water discharge amount is increased by adjusting the flow rate, the water spray holes and the roots of the water transfer prevention protrusions are generated. A water film having a substantially triangular shape with the tip of the water transfer prevention protrusion as the apex is not formed, that is, formation of a water film can be prevented, and water discharged from the water spray holes is pulled toward the water transfer prevention protrusion to It is possible to prevent unintentional water discharge from occurring toward the stopper body and wet the faucet body and its surroundings.
Moreover, in the water tap 20, since the water film formation prevention part is a depression part, the water discharge from a water spray hole is not pulled by the water film formation prevention part.

  FIG. 9 is a schematic diagram of a water discharge port when the shower water discharge port, the dripping prevention protrusion, and the water film formation prevention unit are configured separately. As described above, the shower outlet 405, the drooling prevention protrusion 406, and the water film formation prevention portion 407 may be configured separately, but in this case, it becomes unsanitary such as accumulation of dirt in the gaps between the respective components. there is a possibility. On the other hand, in the faucet 10 and faucet 20 shown in FIGS. 1 to 8, since the shower spout, the dripping prevention protrusion, and the water film formation prevention part are integrally configured, the number of parts is reduced, and the water film formation prevention part. Further, the water transfer prevention protrusions can be formed at a low cost, and the gaps between the parts and the like generated when the protrusions are formed separately can be eliminated, and these can be configured in a sanitary manner.

  Note that the shape of the faucet is not limited to the illustrated one, and it is sufficient that at least the shower outlet is inclined with respect to the upper surface of the counter (the bottom surface of the sink). The arrangement and number of sprinkling holes can also be changed as appropriate. The shape of the water transfer prevention protrusion is not limited to the shape protruding in a substantially vertical direction with respect to the surface of the water discharger as exemplified, but may be any other shape as long as it protrudes from the water spray plate, for example, as shown in FIG. The shape which protruded diagonally downward with respect to the water discharging part may be sufficient. Further, the shower water outlet may be integrated with the water discharge portion as shown in FIGS. 1 to 8, or the shower water discharge portion may be formed separately from the water discharge portion as shown in FIG.
