TECHNICAL FIELD OF THE INVENTION
The present invention relates to a drainage device in which an overflow adapter is externally fitted to a drainage device of a washbasin, and the overflow adapter and the overflow port are connected and communicated to introduce and discharge overflow water into the drainage device. .
[0002]
[Prior art]
Conventionally, as shown in FIG. 2, a drainage device 3 is attached to a drain port 2 of a basin body 1 so that water in a wash bowl is drained to sewage or the like through the drainage device 3 and a drain trap (not shown). ing. Also, when water is released from the hot and cold water mixing faucet or the like while the drainage device 3 is closed, the overflow port 4 is opened on the upper side of the basin body 1 to overflow the basin and wet the floor and the like. are doing. Then, a flange 5 having a male screw portion is inserted into the overflow port 4 from the inside of the basin body 1, and a female screw portion of the overflow elbow 6 is screwed.
[0003]
On the other hand, as shown in FIG. 3, an overflow water receiving port 7 is opened on the peripheral side surface of the drainage device 3, and an overflow adapter 8 is externally fitted to the outer peripheral side of the drainage device 3 to form a double cylindrical structure. The overflow elbow 6 and the inflow port 9 side of the overflow adapter 8 are connected to each other with a bellows hose 10, and overflow water flows from the flange 5 of the overflow port 4 into the drainage device 3 through the overflow elbow 6, the bellows hose 10, and the overflow adapter 8. And discharged to sewage.
[0004]
[Problems to be solved by the invention]
However, in such a conventional drainage device 3 for receiving overflow water, as shown in FIG. 4, two overflow water receiving ports 7 are provided at opposing positions, and the width thereof is Is about 1/4 of the outer circumference of. Therefore, as shown in FIG. 7A, when the receiving port 7 and the inflow port 9 of the overflow adapter 8 face normally, the flow of the overflow water does not matter, but FIG. As shown in the figure, when the position of the receiving port 7 and the inflow port 9 of the overflow adapter 8 are shifted, there is a problem that overflow of the overflow water into the drainage device 3 becomes poor and water overflows from the basin. there were. In order to avoid this, the work of attaching the drainage device 3 and the work of attaching the overflow adapter 8 must be performed carefully, which is extremely troublesome.
[0005]
[Means for Solving the Problems]
The present invention has been improved and removed in view of the above-mentioned conventional problems, and provides a drainage device with a good flow of overflow water without aligning a drainage device inlet with an inlet of an overflow adapter. It's something you want.
[0006]
According to the first aspect of the present invention, a drainage device is attached to a drain port of a wash basin, and an overflow water receiving port is opened on a peripheral side surface of the drainage device. At the same time, the overflow adapter is externally fitted to the peripheral side to form a double cylindrical structure, and in the drainage device with the overflow adapter connected to the overflow port, the peripheral side wall of the drainage device where the overflow water receiving port is not open A drainage device characterized in that one width W is smaller than an inner diameter D of an inflow port of an overflow adapter, and the width W is smaller than a width H of an overflow water receiving port.
According to the present invention, the relationship between the width W of one of the peripheral side walls of the portion of the drainage device where the overflow water port is not open, the inner diameter D of the inflow port of the overflow adapter, and the width H of the overflow water port is described. , W <D, W <H, and no matter which one of the peripheral side walls having the width of W is located, the overflow water does not become larger than the inner diameter D of the inflow port, and overflow water flows into the drainage device. The basin does not get worse and overflow does not overflow from the basin.
[0007]
The means according to claim 2 adopted by the present invention is that the width W of one of the peripheral side walls of the part of the drainage device where the overflow water receiving port is not opened is 1/2 to 2/2 of the inner diameter D of the inflow port of the overflow adapter. 3. The drainage device according to claim 1, wherein the drainage device is 3.
Further, in the present invention, one width W of the peripheral side wall is set to ２〜 to の of the inner diameter D of the inflow port of the overflow adapter. Therefore, regardless of the position of the peripheral side wall, the width of the part where the inlet and the inlet face each other and meet can secure the minimum 1/3 of the inner diameter of the inlet, and the overflow water can be secured. It is possible to secure a sufficient flow.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the configuration of the present invention will be described based on an embodiment of the invention shown in the drawings. The same reference numerals as those in the conventional case denote the same members. FIG. 1 relates to an embodiment of the present invention, and FIGS. 1A and 1B show different positions of the peripheral side wall 12 of the drainage device 3 where the overflow water receiving port 11 is not open. It is a cross-sectional plan view of the drainage device 3 for explaining a case. As shown in the figure, in this embodiment, a total of four overflow water receiving ports 11 of the drainage device 3 are provided, and the width W of the peripheral side wall 12 of the drainage device 3 in a portion where the receiving port 11 is not opened. Is smaller than the inner diameter D of the inflow port 9 of the overflow adapter 8 such that W <D. The width W of the peripheral side wall 12 is set to be smaller than the width H of the overflow water receiving port 11 such that W <H. These dimensional relationships are preferably such that the width W of the peripheral side wall 12 is within a range of １ ／ to ／ of the inner diameter D of the inflow port 9.
[0009]
As described above, the relationship between one width W of the peripheral side wall 12 of the portion of the drainage device 3 where the overflow water receiving port 11 is not open and the inner diameter D of the inflow port 9 of the overflow adapter 8 is W <D, and By setting the relationship between one width W of the peripheral side wall 12 and the width H of the overflow water receiving port 11 to be W <H, even if one of the peripheral side walls 12 having the width of W is located at any position. The overflow water does not become larger than the inner diameter D of the inflow port 9, the overflow water does not flow into the drainage device 3, and the overflow water does not overflow from the basin.
[0010]
One width W of the peripheral side wall 12 is set to １ ／ to ／ of the inner diameter D of the inflow port 9 of the overflow adapter 8. Therefore, regardless of the position of the peripheral side wall 12, the width X of the portion where the inflow port 9 and the reception port 11 face each other and coincide with each other can secure 1/3 of the inner diameter of the inflow port 9 with a minimum. It is possible to easily make overflow water flow into the drainage device 3 and to secure a sufficient flow.
[0011]
【The invention's effect】
As described above, in the present invention, the width W of one of the peripheral side walls of the part of the drainage device where the overflow water receiving port is not open, the inner diameter D of the inlet of the overflow adapter, and the overflow water receiving port The relationship with the width H is specified. Thus, no matter which one of the peripheral side walls having the width of W is located at any position, the inner diameter D does not become larger than the inner diameter D of the inflow port, and the flow of the overflow water into the drainage device can be improved. There is no overflow of overflow water from the vessel.
