Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sink used in a kitchen or the like.

[0002]

2. Description of the Related Art Conventionally, when a hot water storage type water heater is provided above a wall surface of a sink in a kitchen or the like, an overflow pipe is once embedded in a back wall, and its tip is taken out in accordance with the draining position of the sink. After the sink is installed, a custom-made overflow metal fitting for each site is screwed in according to the sink so that overflow water can be discharged from the drainage port of the sink. Alternatively, a dedicated drainage pipe may be installed separately to allow direct drainage without using overflow metal fittings.

[0003]

When the overflow metal fitting is used as in the prior art, since the overflow metal fitting is a custom-made product, it takes much labor and time to manufacture it.
Construction costs are high. Also, since the overflow hardware is screwed in after the sink is installed, the fitting related to the drain connection is not beautiful to look at. In addition, the size of the draining hole is often different from the pipe that is installed in advance and the pipe end is seen from the wall surface. From the point of view of construction, problems such as difficulty in supporting overflow hardware and preventing moisture are pointed out. On the other hand, when a dedicated drainage pipe is provided without using the overflow metal fitting, there is no such problem, but it is inconvenient that it is difficult to visually confirm the overflow condition. In view of the above problems, it is an object of the present invention to provide a sink that can be easily discharged from an overflow pipe used in a hot water storage type water heater and has a clean drain connection.

[0004]

In order to achieve the above object, according to the present invention, a sink having a water tank or the like integrally attached has a discharge opening end at the upper part of the inner wall of the water tank of the sink and is provided on the back side of the sink. A drain having an inflow opening end is provided so that the inflow opening end can be connected to the overflow pipe of the water heater. In addition, the drain is formed into a branched shape,
At least one of the branched ends is a discharge opening end, and the other ends are inflow opening ends. Further, at least one of the plurality of inflow opening ends can be connected to the drain pipe, and the other inflow opening ends are disposed at a position higher than the upper end of the water tank of the sink so that the inflow opening flows into the drain. Discharge of overflow water in the water tank is enabled by the drain pipe.

[0005]

In the present invention, since the discharge opening end is provided on the upper surface of the inner wall of the water tank of the sink and the drain having the inflow opening end is provided on the back side of the sink, the overflow pipe of the water heater is introduced to the above-mentioned inlet. The overflow water can be discharged through the drain to the water tank of the sink by being connected to the open end of the water tank. Further, since the connection with the overflow pipe is made at the opening end for inflow provided on the back side of the sink, unnecessary pipes are not exposed and the surroundings of the sink are clean in appearance. Further, if the drain is formed in a branched shape and a plurality of branch ends other than the discharge opening end provided on the water tank side are used as the inflow opening ends, the inflow opening is matched to the mounting positional relationship between the water heater and the sink. Since the end can be selected, it is easy to make a pipe connection in the field.

In particular, at least one of the inflow opening ends
This allows the water from the overflow pipe of the water heater to flow from the drain pipe in normal times, and, for example, when the drain port of the water tank is clogged, the water overflowing into the water tank Can be led from the discharge opening end of the upper part of the water tank to the drain, flowed into the drain pipe connected at the inflow opening end side, and discharged. Also, by providing another inflow opening end that is not connected to the drain pipe at a position higher than the upper end of the water tank, even if water overflows into the water tank as described above, overflow due to backflow from the unused inflow opening end Can be prevented.

[0007]

Embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the drain 20 is provided on the sink A. A discharge opening end 21 of the drain 20 is provided on the upper side of the inner wall 10a of the water tank 10 of the sink A, and an inflow opening end 22 of the drain 20 is provided on the back side of the sink A.
On the other hand, the overflow pipe 31 of the water heater 30 attached to the back wall B is once embedded in the back wall B, and then the pipe end 30a is exposed from the back wall B surface. This pipe end 30
a and the inflow opening end 22 are connected via a heat resistant hose 40 having flexibility.

The inflow opening end 22 side of the drain 20 is bent so that the inflow opening end 22 is open upward so that the heat-resistant hose 40 can be easily attached. Further, the inflow opening end 22 is opened at a position higher than the upper end 10b of the water tank 10. When connecting the overflow pipe 31, the heat-resistant hose 40, and the inflow opening end 22, a commercially available pipe joint member (not shown) may be appropriately used together with a sealing member or the like.

Further, the drain 20 shown in FIG.
It is formed in a branched tubular shape that opens toward one side. The branch end side of the drain 20 formed in the branched pipe is formed at the discharge opening end 21 provided on the water tank 10 side as described above. The two branch ends on the other end are connected to the overflow pipe 3 as described above.
Opening end 2 for inflow that can be connected to 0 via heat-resistant hose 40
3 and 24. This inflow opening end 23, 2
Similarly to the inflow opening end 22, the fourth side is also bent so as to open upward at a position higher than the upper end 10b of the water tank 10. Further, the inflow opening end 23 is formed so as to open to the drainage 50 portion on the inner side of the sink. The inflow opening ends 23 and 24 are configured to be closed by a plug (not shown) when not in use.

Further, the drain 20 shown in FIG.
It is formed in a substantially cross shape having two open branch ends. One of the plurality of branch ends is formed at the discharge opening end 21 that opens into the water tank 10 as described above. Two of the remaining three branch ends can be connected to the overflow pipe 31, and are formed at the inflow opening ends 25 and 26 that are open upward at a position higher than the upper end of the water tank 10, and the inflow opening end 25 is the above-mentioned. As described above, an opening is made on the surface of the drainer 50. Furthermore, the remaining one branch end is opened vertically downward,
The open end 27 is used to connect to the drain pipe 60. The other end of the drainage pipe 60 is connected to the drainage pipe 70 for drainage of the water tank 10 so as to be able to join.

In the present embodiment, the drain pipe 60 is joined to the drain pipe 70 for the water tank 10. However, the drain pipe 60 may be laid so that the drainage can be performed by another route. Furthermore, the inflow opening end 2 of the drain 20 that does not branch
2 may be connected to the overflow pipe at one end and to the drain pipe at the other end via a pipe joint member (for example, a T-shaped joint, a cross joint, etc.).

[0012]

As described above, according to the present invention, it is possible to save the labor of the drain pipe and the mounting of the water heater when the sink is mounted. Further, by providing the connection portion between the drain of the sink and the overflow pipe on the back surface of the sink, it is possible to clean the appearance of the drain around the sink. Further, conventionally, the drain pipe was connected by connecting the overflow pipe with a custom-made metal item for each site, but the sink with drain of the present invention can be standardized, reducing the labor of manufacturing and construction and reducing the cost. Can be actively pursued.
