  The present invention relates to a drainage device for a bathroom, in which blockage of drainage by foreign substances is eased and cleaning property is improved.

  Conventionally, in this type of bathroom drainage apparatus, a handle protruding upward is disposed at the center of the strainer (see, for example, Patent Document 1).

3 and 4 show a conventional bathroom drainage device. As shown in FIGS. 3 and 4, the strainer 1 has a concave shape downward, is symmetric with respect to the drain outlet center of the drainage device, and the bottom 3 of the concave portion 2 is formed in a horizontal plane. It is the structure which has the handle 4 which protruded upwards from the center of the recessed part 2 of this.
JP-A-8-270038

  However, in the conventional configuration, since the bottom surface of the concave portion is a flat surface, if the foreign matter stays, it spreads over the bottom surface, the drainage passage is easily blocked, and foreign matter such as hair staying in the strainer is removed and cleaned. In some cases, foreign matter must be removed directly by hand, or the strainer must be turned upside down with a handle protruding from the center. Even in the latter case, the foreign matter falls on the hand, and in both the former and the latter case, there is a problem that the foreign matter touches the hand and gives unpleasant feeling.

  The present invention solves the above-mentioned conventional problems, and the present invention makes it difficult for the drainage passage to be blocked even when foreign matter stays in the strainer, and the foreign matter stays in the strainer without touching it directly. The purpose is to simplify the cleaning.

In order to solve the above-mentioned conventional problems, the drainage device for a bathroom of the present invention has a strainer detachably installed at a drain outlet, and the strainer has a water flow that protrudes in a substantially conical shape from the inside of the outer edge and the outer edge. A part is formed integrally, and at least a part of the water passage part is net-like, and the position of the apex of the substantially conical shape is decentered from the center of the drain outlet. Furthermore, the strainer is provided with a handle at a position facing the apex of the water flow portion with respect to the center, and a smooth surface that does not form a part of the water flow portion near the attachment position of the handle in a net shape. It is.

As a result, the foreign matter collects and stays in the vicinity of the apex of the eccentric substantially conical surface of the strainer, and the reticulated flow channel on the upper portion of the approximately conical surface is not easily blocked. In addition, since the handle is positioned away from the apex of the water passage where foreign matter stays, the strainer can be removed without directly touching the foreign matter when cleaning the strainer. In addition, the vicinity of the handle attachment position is a smooth surface that does not form a water-permeable part in a net-like shape, so that foreign matter that flows in along with drainage from the surroundings is not caught on the smooth surface of the water-permeable part of the strainer. Can be collected near the apex of the substantially conical surface.

In the bathroom drainage device of the present invention, even if foreign matter stays in the strainer, the channel is not easily blocked, the drainage channel is ensured, and the cleaning property can be improved. In particular, when cleaning the strainer, the strainer can be removed without touching the foreign object directly, and there is less foreign matter staying near the handle, making it even less likely to touch the foreign object. The strainer can be removed.

According to a first aspect of the present invention, a strainer is detachably installed in the drain port, and the strainer integrally forms an outer edge portion and a water passage portion projecting in a substantially conical shape below the inner side of the outer edge portion, and at least one of the water passage portions. The part is net-like and the position of the apex of the substantially conical shape is decentered from the center of the drain, so that when the foreign object stays in the strainer, the foreign object stays near the apex of the conical surface. Foreign matter does not stay in the upper net-like portion, and blockage of the drainage channel can be prevented.
In addition, by providing a handle at a position opposite to the top of the water passage with respect to the center of the strainer, the handle is positioned away from the top of the water passage where foreign matter stays. When performing, the strainer can be removed without directly touching the foreign object.
In addition, the vicinity of the attachment position of the handle is a smooth surface that does not form a water passage portion in a mesh shape, so that foreign matter that flows along with drainage from the surroundings is not caught on the smooth surface of the water passage portion of the strainer. Since they can be concentrated near the apex of the lower substantially conical surface, there is less stagnation of foreign matter in the vicinity of the handle, the touch of the foreign matter is further reduced, and the strainer can be removed in a sanitary manner.

In the second invention, in particular, the handle of the strainer of the first invention is made into a V shape or a wedge shape in which the cross-sectional shape of the shaft portion extends toward the center, so that the drainage flows in from behind the handle. Since the foreign matter can be smoothly guided into the water passing portion without being wound around the shaft portion of the handle, the strainer can be removed hygienically with less touching the foreign matter.

In the third invention, in particular, by coating the surface of the strainer of the first or second invention with a fluororesin, it becomes difficult for the surface of the strainer to stick to the surface of the strainer, and foreign matter and dirt are less likely to adhere to the strainer. Cleaning becomes easier.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.
