Description

  The present invention relates to a washbasin, and more particularly to a washbasin having an overflow port.

  Conventionally, an overflow port is provided in an upper part of a bowl portion in a wash basin or the like in order to prevent the stored water from overflowing. The overflow port is connected to an overflow drain pipe disposed outside the bowl portion by, for example, an elbow pipe. A drain outlet is provided on the bottom of the bowl, and the basin is drained by connecting an overflow drain pipe extending from the overflow outlet to a drain pipe continuous from the drain outlet. (For example, refer to Patent Document 1).

  Since the drain pipe is attached to the outside of the washbasin, there is a demand for making the appearance inconspicuous. In view of this, a technique has been proposed in which the bowl portion and the overflow drain pipe having a hollow structure are formed separately, and insert molding is performed together with a metal fitting for connecting them (for example, see Patent Document 2).

The overflow drainage channel joins the drainage channel of the bowl part 2 by connecting the overflow drainage pipe 32 to the drainage pipe connection part 24 extending from the drainage port 21 on the bottom surface of the bowl part 2.

  This overflow drainage channel is covered with an overflow cover portion 33 above the bowl portion 2. The overflow port 31 is formed in a substantially rectangular shape, and the drainage passage is formed by the overflow cover portion 33 without greatly reducing the width from the overflow upper surface portion 331 to the lower end of the overflow side surface portion 333. More than 10 liters of water can be drained per minute.

  The basin 1 having the bowl portion 2 and the overflow portion 3 is made of resin and is integrally formed by press molding. The overflow port 31 of the bowl part 2 may be integrally formed so that a hole is formed at the same time during press molding, or may be formed by opening a hole in the bowl part 2 later.

FIG. 7 shows a state of use of the washbasin 1 of the present embodiment.
The wash basin 1 is arranged in a so-called Bessel type so that the counter 100 is disposed under the rib portion 332 and the upper side of the rib portion 332 protrudes from the counter 100. That is, the rib part 332 is placed on the counter 100 and demarcates the boundary between the washbasin 1 and the counter 100.
In more detail, the rib part 322 is arrange | positioned at the half vessel type arrange | positioned in the position higher than the drain outlet 21 arrange | positioned at the bottom face of the bowl part 2. FIG.

  As shown in FIG. 7, when the user stands in front of the basin 1, even if the basin 1 is arranged so as to protrude above the counter 100, the overflow cover portion 33 is not easily seen by the user. The drainage structure of the overflow part 3 is not conspicuous.

According to the washbasin 1 of this embodiment, there exist the following effects.
(1) The basin 1 is connected to the bowl portion 2, the drain port 21 formed on the bottom surface of the bowl portion 2, the overflow port 31 formed on the back surface of the bowl portion 2, and one end side connected to the overflow port 31. An overflow drainage channel extending downward, and an overflow cover portion 33 that protrudes from the back surface of the bowl portion 2 to the back side and covers the overflow drainage channel are configured. In addition, the overflow cover portion 33 is configured to include an overflow upper surface portion 331 that is inclined downward so that it is difficult for the user of the basin 1 to visually recognize the user when standing on the front side of the bowl portion 2.
As a result, the overflow cover portion 33 covers the overflow drainage channel for draining water from the overflow port 31 on the back side of the overflow port 31, so that the structural portion such as the connection portion of the pipe is not visually recognized, and the appearance is clean Will improve. In addition, since mechanically fine structures such as screws are not exposed, dust and dirt are not collected and it is hygienic. In addition, since the overflow cover portion 33 is inclined downward so that it is difficult to visually recognize when the user stands on the front side of the bowl portion 2, for example, when the basin 1 is placed on the counter 100 and installed. However, the overflow drain pipe 32 and the like are not visually recognized, and the design is improved.

(2) The overflow upper surface portion 331 was inclined at an angle of 45 degrees or more with respect to the horizontal plane. Thereby, when a user stands on the near side of bowl part 2, it becomes difficult to see surely. Therefore, the same effect as described above can be achieved more reliably.

(3) The overflow cover portion 33 is disposed at the lower end portion of the overflow upper surface portion 331, the rib portion 332 extending horizontally from the lower end portion, and the overflow side surface disposed below the rib portion 332 and extending downward. Part 333. Thereby, since the rib part 332 is extended in a horizontal direction, the structure below the rib part 332 becomes difficult to visually recognize from the upper part of the washbasin 1, and the design property improves. Further, by configuring the overflow side surface portion 333 to extend below the rib portion 332, the flow path of the drainage channel covered by the overflow cover portion 33 can be made thick.

(4) The counter 100 was disposed on the lower surface of the rib portion 332, and the vessel was used as a vessel-type basin in which the upper side of the rib portion 332 protrudes from the counter 100. As a result, the rib portion 332 makes the boundary between the washbasin 1 and the counter 100 clear, and the rib portion 332 is placed on the counter, so that the washbasin 1 is not easily dropped from the hole for installing the washbasin 1 provided on the counter 100, Easy to install.

(5) The rib portion 332 was positioned higher than the bottom surface of the bowl portion 2. Thereby, the height of the rib part 332 can be restrained low, and the depth of the bowl part 2 can be deepened. As described above, the half vessel type wash basin 1 in which the outer surface portion of the bowl portion 2 partially protrudes from the counter 100 has the same effect as described above.

(6) The overflow drainage channel was configured to be able to drain 10 liters or more of water per minute. Thereby, since a sufficient amount of drainage can be secured, concerns such as water overflowing outside the basin 1 are reduced, and the function of the overflow part 3 is improved. Further, since a sufficient amount of drainage can be secured, for example, the bowl portion 2 can be designed in a shape like a shallow dish, which improves design and increases the number of places where the basin 1 can be installed.

(7) The basin 1 was integrally formed by press molding. Thereby, the bowl part 2 and the overflow part 3 are integrally formed, and the overflow drain pipe 32 is connected to the lower end part of the overflow side part 333 of the overflow cover part 33 via the overflow cover connection part 34 or the like. Can do. Therefore, the overflow drain pipe 32 can be easily attached. Furthermore, since the overflow drain pipe 32 can be connected and attached below the overflow portion 3, the structure portion of the piping is not visually recognized from the outside even when the basin 1 is placed on the counter 100.

As mentioned above, although each preferred embodiment of the present invention was described, the present invention is not limited to each embodiment mentioned above, and can be changed suitably.
For example, in the above-described embodiment, the overflow port 31 and the overflow cover portion 33 are formed in a horizontally long shape along the longitudinal direction of the washbasin 1. However, the present invention is not limited to this. The shapes of the overflow port 31 and the overflow cover portion 33 can be appropriately changed according to the design, such as a circle.

  Moreover, although the said embodiment demonstrated the half vessel type washbasin 1 installed so that the bowl part 2 might protrude on the counter 100, it is not restricted to this. The bowl portion 2 may be installed in a Bessel type such that the bottom surface is located above the counter, or may be installed so that most of the bowl portion 2 is below the counter surface of the counter.
