Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a drainage structure for a vanity.

[0002]

2. Description of the Related Art FIG. 9 is a view showing a conventional drainage structure of a vanity. As shown in FIG. 9, an overflow port 901 is provided in the washbasin 101 so that overflow water flows under the drain plug.

[0003]

The conventional drainage structure of the vanity has an overflow port below the overflow surface of the wash bowl in order to drain the overflow water.
Therefore, it is easy for the overflow port to get dirty, and
It has a problem that it is difficult to clean and the appearance is spoiled. Therefore, the present invention has been made to solve the above-mentioned problems, and by eliminating the overflow port inside the washbasin, dirt is less likely to adhere, cleaning is easier, and the washbasin has improved aesthetics. The purpose is to provide a drainage structure for the platform.

The invention according to claim 1 is
In a drainage structure such as a vanity having an overflow function, an overflow port is provided on the downstream side of the drain port at the bottom of the wash bowl, the overflow unit section has a ventilation port on the upper side, and a drain plug closing section is provided on the downstream side of the overflow port. It is characterized by having.

According to the present invention, the overflow port is provided on the lower side of the drain port in the lower part of the wash bowl, the overflow unit part is provided with the ventilation port on the upper part, and the drain plug closing part is provided on the downstream side of the overflow port. As a result, the overflow port is not provided in the wash bowl, so that the wash bowl is less likely to become dirty and is easy to clean, and the appearance can be improved.

According to a second aspect of the present invention, in the drainage structure according to the first aspect, the overflow unit portion is provided with a water sealing portion, and the drain side connection portion of the overflow unit portion is the wash surface. It is characterized in that it is connected to the downstream side of a drain trap connected to the downstream side of the drain port at the bottom of the bowl.

According to the present invention, the overflow unit section is provided with a water sealing section, and the drain side connection section of the overflow unit section is connected to the downstream side of the drain port at the lower part of the wash bowl. Since it is connected to the downstream side of the drain trap, there is no overflow port inside the wash bowl, so the wash bowl is less likely to become dirty and easier to clean, and the appearance can be improved, and a separate vent is required. There is no need to worry about clogging of the vents and water leakage from the vents.
Easy to configure.

According to a third aspect of the present invention, there is provided a drainage structure according to the first or second aspect, further comprising a perforated plate having a plurality of holes in a bottom surface portion and a side surface portion which cover the drainage port above the drainage port. It is characterized by being attached.

According to the present invention, a drain plate is attached to the upper part of the drainage port and a plurality of holes are provided in the bottom face and the side face to cover the drainage port. Even if the bottom surface of the drainage port is blocked with, for example, dust, the water drained from the opening on the side surface of the perforated plate can flow into the overflow port and perform an overflow function.

According to a fourth aspect of the present invention, in the drainage structure according to any one of the first to third aspects, the overflow unit portion is integrally formed with the wash bowl.

According to the present invention, since the overflow unit is integrally formed with the wash bowl, the number of connection points is reduced as compared with the case where the overflow unit is provided as a separate component, and there is no fear of water leakage. In addition, the cost of parts can be reduced and the cost can be reduced.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described more specifically with reference to the drawings. FIG. 1 is a sectional view showing an embodiment of the present invention. The wash bowl 101 has a drain port 1 at the bottom.
05, and the overflow unit section 103 is connected below the drain port 105. The wash bowl 101 is generally made of pottery, but may be made of acrylic or polyester resin, metal such as stainless steel, or glass. The drain head 201 and the overflow unit 103 are made of resin such as ABS or PP or metal such as stainless steel.

FIG. 2 is a detailed view of the drain head 201 portion shown in FIG. Below the overflow port 204, there is a drain plug closing part 202, and below that, an overflow water merging port 203 is connected. FIG. 2 shows the drain plug closing part 2
02 shows the case where it is in a closed state. At this time, if water is supplied to the wash bowl 101, water will be accumulated in the overflow unit section 103 up to the same water level as the wash bowl 101 until the water level reaches the overflow line 106, but if more water is supplied, it will become overflow water and overflow below. It is drained from the water confluence port 203.
On the other hand, when the drain plug closing part 202 is open, the drain port 105
The water flowing in from the above flows to the drain trap unit 102 as it is.

FIG. 3 is a view showing an example of a vent hole portion of the overflow unit portion. The inside of the pipe of the overflow unit 103 is preferably open to the atmosphere, but in order to prevent water leakage or dust intrusion from the vent 104, for example, a mesh cap 301 or the like is attached to the vent 302 so that only air enters and exits. It is preferable to have a structure that

FIG. 4 is a diagram showing an example of an overflow unit section having a water sealing section. In the overflow unit section 103 including the water sealing section 401, the overflow water merging port 203 is connected to the lower part of the drain trap section 102. In this case, there is no need to provide a separate vent, there is no concern about clogging of the vent and water leakage from the vent, and the configuration is simple.

FIG. 5 is a view showing an example in which a plate is attached to the upper part of the drainage port. FIG. 6 and FIG. 7 are views showing an example of the shape of the plate. The plate 501 has a bottom surface 502 and a side surface 503.
A plurality of holes are provided in the water, and the water flowing into the wash bowl 101 flows into the drain port 105 through the plurality of holes in the dish 501. When the drain plug closing part 202 (see FIG. 2) is closed and the bottom part 502 of the eye plate 501 is clogged with dust or the like, water mainly flows in from the side surface part 503 of the eye plate 501 and flows into the drain port 105. Good overflow performance can be maintained by flowing through the overflow port 204.

FIG. 8 shows the overflow unit section 103.
FIG. 4 is a cross-sectional view showing one embodiment in the case where it is integrally formed with the wash bowl 101. The inside of the overflow unit 103, which is integrally formed with the wash bowl 101, is divided by a partition 801. Therefore, the water flowing from the overflow port 204 accumulates to the same water level as the wash bowl 101 in the overflow unit section 103 until the water level reaches the overflow line 106, but if more water is supplied, it will become overflow water and It is drained from the overflow water confluence port 203.
The vent 104 is open to the atmosphere so that good overflow performance can be obtained.
