JP-A-10-237913

However, the conventional one has the following problems.

First, since a plurality of water supply openings are open in the shape of a horizontal hole in the side surface of the washing water tank, if the water pressure supplied to the annular branch water supply pipe is high, each water supply opening is directed to the inside of the washing water tank. The water will be sprinkled. For this reason, depending on the water pressure, it may not be possible to sufficiently wash away hair, dust, etc. adhering to the side surface of the washing water tank. In order to avoid this, it is necessary to adjust the water pressure.

Secondly, since the water supply port is exposed on the side surface of the cleaning water tank, dust and dirt may enter the water supply port when the cleaning water is not flowing.

Thirdly, the fact that the water supply port is exposed on the side surface of the washing water tank is negative in terms of design, and there is a risk that some users may feel uncomfortable, for example, the sense of cleanliness is impaired.

The present invention has been made in view of the circumstances as described above, the inner peripheral surface is reliably washed by the washing water coming out from the washing water discharge port, there is no possibility that dust or the like enters the washing water discharge port, It is intended to provide a sink that has no negative elements in terms of design.

In order to solve the above problems, a sink according to the present invention includes a bottom surface having a drain port, an inner peripheral surface continuous with the bottom surface, and a cleaning water discharge that supplies cleaning water to the inner peripheral surface in communication with water supply means. An outlet, and the cleaning water discharge port is formed downward along the entire upper periphery of the inner peripheral surface (Claim 1).

In the present invention, the cleaning water is supplied from the water supply means to the cleaning water discharge port, and the inner peripheral surface is cleaned by the cleaning water flowing out from the cleaning water discharge port. Since the washing water discharge port is provided downward, the washing water supplied from the washing water discharge port surely flows down along the inner peripheral surface of the sink without being influenced by the water pressure. For this reason, the inner peripheral surface is reliably cleaned with the cleaning water. Further, since the cleaning water discharge port faces downward, it is difficult for dust or the like to enter the cleaning water discharge port even when the cleaning water does not flow out. Furthermore, the downward cleaning water discharge port is not easily seen by the user. For this reason, it does not become a design unfavorable appearance and can also prevent the user from being offended.

As one preferred embodiment, a cleaning water reservoir communicating with the water supply means is disposed along the entire circumference of the inner peripheral surface, and the upper edge of the cleaning water reservoir is horizontal over the entire circumference, A mode in which the washing water overflowing from the horizontal upper edge flows out from the washing water discharge port will be exemplified (claim 2). In this case, the cleaning water supplied from the water supply means accumulates in the cleaning water reservoir, overflows from the horizontal upper edge of the cleaning water reservoir, and flows out from the cleaning water discharge port.

The cleaning water discharge port only needs to be provided along the entire circumference of the inner peripheral surface, and a large number of cleaning water discharge ports may be arranged with a small space between them. A single washing water discharge port connected without a break along the inner peripheral surface may be provided (Claim 3). If it is set as the latter aspect, the washing water is supplied to the entire circumference of the inner peripheral surface without any gap, which is preferable.

As a preferred embodiment, a mode including a cover that covers the cleaning water reservoir and the cleaning water discharge port from above is exemplified (Claim 4). In this way, the upper cover prevents the cleaning water reservoir and the cleaning water discharge port from entering the dust, and a design-friendly appearance can be obtained.

As one preferred embodiment, an outlet that communicates with the water supply means is formed along the entire upper periphery of the inner peripheral surface, and a cleaning water guide that guides the cleaning water flowing out from the outlet downward The aspect arrange | positioned along a surrounding surface and the clearance gap between this inner peripheral surface and the lower end part of the said washing water guide is illustrated as the said washing water discharge port (Claim 5). In this case, the cleaning water flowing out from the outlet is guided downward toward the cleaning water discharge port by the cleaning water guide. For this reason, there is no problem even if the water pressure of the washing water flowing out from the outlet is high.

In addition, the said outflow port should just be provided along the perimeter of the said internal peripheral surface, It is good also as arrange | positioning many outflow ports at a small space | interval between each other, and the said internal peripheral surface It is good also as arrange | positioning the single outflow port connected without a cut | interruption along (Claim 6). If it is set as the latter aspect, the washing water is supplied to the entire circumference of the inner peripheral surface without any gap, which is preferable.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 to 6, a sink 1 according to an embodiment of the present invention includes a bottom surface 3 having a drain port 2 and an inner peripheral surface 4 continuous with the bottom surface 3. Objects such as hands and articles can be washed in the sink 1 by supplying water from the faucet 5 (see FIG. 6) communicating with the water pipe. The water supplied into the sink 1 flows out from the drain port 2 and is discharged to a sewer or the like through a drain pipe (not shown) connected to the drain port 2. The sink 1 should just be produced with the material according to various uses, such as a product made from stainless steel, the product made from earthenware, the product made from porcelain, and the product made from glass, and there is no limitation in a material and an application.

As shown in FIGS. 5 and 6, the sink 1 includes a cleaning water discharge port 6 for supplying cleaning water to the inner peripheral surface 4. As shown in FIG. 1, the washing water discharge port 6 communicates with water supply means 8 such as a water pipe or a washing water tank with a pump through a water supply pipe 7. The cleaning water flows out from the cleaning water discharge port 6 by opening the valve 9 as an example of the operating means provided on the water supply pipe 7 as necessary. The washing water supplied from the water supply means 8 can be appropriately determined according to the use, such as washing water containing disinfecting liquid and washing water containing fragrance, in addition to fresh water. For example, tap water is used in sinks such as kitchens, kitchens, and washrooms, wash water containing disinfectant is used in sinks for hand washing of medical institutions or medical equipment, and scents are used in sinks such as hotel toilets. For example, use washing water.

In the present embodiment, the washing water discharge port 6 is formed downward along the entire upper periphery of the inner peripheral surface 4 of the sink 1. Specifically, it is as follows.

As shown in FIGS. 5 and 6, the cleaning water reservoir forming plate 10 is fixed along the entire outer periphery of the inner peripheral surface 4 of the sink 1. As shown in an enlarged view in FIG. 7, the cleaning water reservoir forming plate 10 includes a bottom plate portion 12 fixed to the entire circumference of the outer peripheral surface 11 of the sink 1, and an outer plate extending upward from the outer end portion of the bottom plate portion 12. Portion 13, an upper plate portion 14 extending from the upper end of the outer plate portion 13 to the inside of the sink 1 beyond the upper edge portion 4 a of the inner peripheral surface 4 of the sink 1, and extending downward from the upper plate portion 14. An inner plate portion 15. As a result, an annular cleaning water reservoir 16 is formed between the cleaning water reservoir forming plate 10 and the outer peripheral surface 11 of the sink 1. A clearance between the upper edge 4 a of the inner peripheral surface 4 of the sink 1 and the upper plate portion 14 of the cleaning water reservoir forming plate 10 is a cleaning water outlet 17. Moreover, the gap between the inner peripheral surface 4 of the sink 1 and the lower end of the inner plate portion 15 of the cleaning water reservoir forming plate 10 is the downward cleaning water discharge port 6.

The upper plate portion 14 is a cover (upper cover) that covers the cleaning water reservoir 16, the outlet 17 and the cleaning water discharge port 6 from above, and the inner plate portion 15 is a cover (side) that covers the outlet 17 from the side. Direction cover). These covers 14, 15 cover and hide the cleaning water reservoir 16, the outlet 17, and the cleaning water discharge port 6. For this reason, entry of dust into the washing water discharge port 6, the outlet 17, and the washing water reservoir 16 is prevented. Further, since the washing water reservoir 16, the outlet 17 and the washing water discharge port 6 are hidden from the eyes of the user of the sink 1, it is preferable in terms of design, and there is no problem of harming the user's mood. In addition, the inner plate part 15 as a side cover extends to a position below the outlet 17 from the viewpoint of reliably preventing dust from entering and reliably hiding the outlet 17 from the eyes of the user. It is preferable. Moreover, although the upper board part 14 and the inner board part 15 are united with the outer board part 13, you may comprise with the top plate of another member called what is called a worktop.

The washing water reservoir 16 communicates with the water supply means 8 via the water supply pipe 7 (see FIGS. 1, 4 and 6). In the example of illustration, although the water supply pipe line 7 is provided in the back side of the sink 1, it is not limited to this. The upper edge of the cleaning water reservoir 16, that is, the upper edge 4a of the inner peripheral surface 4 of the sink 1 in the illustrated example is horizontal over the entire circumference. For this reason, when the cleaning water W is supplied from the cleaning means 8 to the cleaning water reservoir 16, the cleaning water W accumulates in the cleaning water reservoir 16, the water level of the cleaning water W rises, and eventually the upper edge of the cleaning water reservoir 16 is reached. The washing water W overflows from the outlet 17 all at once over the part 4a. The washing water W overflowing from the outlet 17 flows down from the washing water discharge port 6 along the inner peripheral surface 4 of the sink 1. For this reason, the washing water W spreads over the entire inner peripheral surface 4 of the sink 1, and the dirt on the inner peripheral surface 4 is washed away cleanly.

The outlet 17 and the washing water discharge port 6 may be provided along the entire circumference of the inner peripheral surface 4 of the sink 1, and a large number of outlets and washing water are spaced apart from each other. It is good also as arrange | positioning a discharge port, and good also as arranging the single outflow port 17 and the washing water discharge port 6 which connect along the inner peripheral surface 4 of the sink 1 seamlessly. If it is set as the latter aspect, the washing water W will be supplied to the perimeter of the internal peripheral surface 4 without a gap, and it is suitable.

How the cleaning water W flows out from the cleaning water reservoir 16 depends on the capacity of the cleaning water reservoir 16, the flow rate of the cleaning water W supplied to the cleaning water reservoir 16, the total area of the outlet 17, and the like. Determined. For example, as shown in FIG. 7, when both the capacity of the cleaning water reservoir 16 and the total area of the outlet 17 are large, and the flow rate of the cleaning water W is not so large, the cleaning water is discharged from the outlet 17. W gradually overflows. Therefore, the cleaning water W flows down from the cleaning water discharge port 6 along the inner peripheral surface 4 from the upper edge 4 a of the inner peripheral surface 4 of the sink 1.

On the other hand, as shown in FIG. 8, when the total area of the outlet 17 is small and the flow rate of the washing water W is large, the outlet 17 moves inward (arrow A). Washing water W spouts out. In this case, the cleaning water W ejected from the outlet 17 collides with the inner plate portion 15 of the cleaning water reservoir forming plate 10 and is guided downward. Therefore, the inner plate portion 15 in this case acts as a washing water guide for guiding the washing water W ejected from the outlet 17 downward.

As already described with reference to FIG. 7, when the capacity of the cleaning water reservoir 16 and the total area of the outlet 17 are both sufficiently large and the flow rate of the cleaning water W is not so large, Wash water W gradually overflows from the outlet 17. For this reason, the wash water W flows down from the upper end edge 4 a of the inner peripheral surface 4 of the sink 1 along the inner peripheral surface 4. Therefore, in this case, as shown in FIG. 9, the inner plate portion 15 of the cleaning water reservoir forming plate 10 can be omitted. As long as the upper plate portion 14 of the washing water reservoir forming plate 10 extends in a bowl shape to the inside of the sink 1 beyond the flowing water port 17, the upper plate portion 14 acts as an upper cover. Since the upper cover 14 covers the cleaning water reservoir 16 and the outlet 17 from above, the entrance of dust into the cleaning water reservoir 16 and the outlet 17 is prevented. Moreover, since the upper cover 14 hides the washing water reservoir 16 and the outlet 17 from the eyes of the user of the sink 1, it is preferable in terms of design, and there is no problem of harming the user's mood. In this case, the outlet 17 also serves as the washing water discharge port 6.

In addition, in the example of FIG. 9, the washing water discharge port 6 (flow water port 17) is sideways. However, since the same effect as FIG. 7 is acquired by the said structure, it is in the scope of the present invention.

As another embodiment, the mode shown in FIG. 10 can be adopted. That is, the cleaning water reservoir 16 is disposed inside the inner peripheral surface 4 of the sink 1. In this case, the cleaning water reservoir forming plate 18 is formed in a bowl shape and fixed to the inside of the upper portion of the inner peripheral surface 4 of the sink 1 by the upper plate portion 19. A cleaning water reservoir 16 is formed by the bowl-shaped portion 20 of the cleaning water reservoir forming plate 18. A water supply means 8 communicates with the cleaning water reservoir 16 through a water supply pipe 7 as in FIG. A gap between the upward free edge 20 a of the bowl-shaped portion 20 and the upper plate portion 19 serves as an outlet 17 for the cleaning water W. Further, in the cleaning water reservoir forming plate 18, a gap between the lower end of the facing plate portion 21 facing the inner peripheral surface 4 of the sink 1 and the inner peripheral surface 4 of the sink 1 is the cleaning water discharge port 6. Become.

In the case of the example in FIG. 10, if the gap between the facing plate portion 21 and the inner peripheral surface 4 of the sink 1 is too large, the washing water W overflowing from the outlet 17 will not hit the inner peripheral surface 4 of the sink 1. End up. For this reason, the clearance gap between the facing plate part 21 and the inner peripheral surface 4 of the sink 1 is set suitably so that the washing water W which overflows from the outlet 17 may flow down along the inner peripheral surface 4 of the sink 1.

In FIG. 10, the upper plate portion 19 is a cover (upper cover) that covers the cleaning water reservoir 16, the outlet 17, and the cleaning water discharge port 6 from above. With this cover 19, the cleaning water reservoir 16, the outlet 17 and the cleaning water discharge port 6 are covered. For this reason, entry of dust into the cleaning water reservoir 16, the outlet 17 and the cleaning water discharge port 6 is prevented. In addition, since the washing water reservoir 16, the outlet 17 and the washing water discharge port 6 are hidden from the eyes of the user of the sink 1, it is preferable in terms of design, and there is no problem of harming the user's mood.

In the configuration of FIG. 10, the upper edge portion of the cleaning water reservoir 16, that is, the upper edge portion 20 a of the facing plate portion 21 is horizontal over the entire circumference of the inner peripheral surface 4 of the sink 1. For this reason, when the cleaning water W is supplied from the cleaning means 8 to the cleaning water reservoir 16, the cleaning water W accumulates in the cleaning water reservoir 16, the water level of the cleaning water W rises, and eventually the upper edge of the cleaning water reservoir 16 is reached. The washing water W overflows from the outlet 17 all at once over the part 20a. The washing water W overflowing from the outlet 17 flows down from the washing water discharge port 6 along the inner peripheral surface 4 of the sink 1. For this reason, the washing water W spreads over the entire inner peripheral surface 4 of the sink 1, and the dirt on the inner peripheral surface 4 is washed away cleanly.

Also in the example of FIG. 10, a large number of the outlets 17 and the washing water discharge ports 6 may be arranged with a small space between each other, and there is no break along the inner peripheral surface 4 of the sink 1. It is good also as arrange | positioning the single outflow port 17 and the washing water discharge port 6 which connect. If it is set as the latter aspect, the washing water W will be supplied to the perimeter of the inner peripheral surface 4 of the sink 1 without a gap, and it is suitable.

As another embodiment, the mode shown in FIG. 11 can be adopted. In other words, the water pipe 22 corresponding to the washing water reservoir is arranged horizontally over the entire inner circumference of the upper peripheral surface 4 of the sink 1. In this case, the washing water discharge port 6 is formed downward on the lower surface of the water conduit 22 so as to be close to the inner peripheral surface 4 of the sink 1. A large number of the washing water discharge ports 6 may be arranged at small intervals in the length direction of the water pipe 22, or may be a single washing water discharge port connected seamlessly in the length direction of the water pipe 22. Good.

The water supply means 8 communicates with the water pipe 22 through the water supply pipe 7 as in FIG. When the cleaning water W is supplied to the water pipe 22 through the water supply pipe 7, the cleaning water W flows through the water pipe 22 and flows down from the cleaning water discharge port 6. The cleaning water W flowing down from the cleaning water discharge port 6 flows along the inner peripheral surface 4 of the sink 1 to clean the inner peripheral surface 4.

Since the cleaning water discharge port 6 is provided on the lower surface of the water pipe 22, entry of dust from the cleaning water discharge port 6 into the water pipe 22 is prevented. Moreover, since the washing water discharge port 6 cannot be seen from the eyes of the user of the sink 1, it is preferable in terms of design, and there is no problem that the user's mood is harmed.

The embodiment of FIG. 11 can be produced by retrofitting the water flow pipe 22 to the inner peripheral surface 4 of the sink 1, so that the existing sink can be used as it is.

As other embodiments, the modes shown in FIGS. 12 and 13 may be employed. That is, the example of FIG.12 and FIG.13 is a modification of FIG. 8, and the upper part of the internal peripheral surface 4 of the sink 1 is pierced and many water flow ports 17 are formed.
