Description

  The present invention relates to a drainage structure for a bowl used for hand-washing and washing, and more particularly to a drainage structure for a bowl in which dirt is hardly generated at a drainage port formed at the bottom of the bowl.

  Conventionally, a drainage structure of a bowl in which a drain outlet is formed at the bottom of the bowl, a connecting fitting is connected to the drain outlet, and a drain pipe is connected to the connecting fitting is disclosed in Patent Document 1. This conventional bowl drainage structure is a cylindrical member (top end) that forms a drainage passage as described in [0021] and [0022] of Patent Document 1 when a connecting metal fitting is coupled to the drain outlet at the bottom of the bowl. A flange is provided at the bottom and a male thread is provided at the lower end. A tightening nut is screwed into the male thread at the lower end. The cylindrical member is attached to the bottom of the bowl while being sandwiched. The drain plug is provided at the upper end opening of the cylindrical member so as to be movable up and down.

In this conventional bowl drainage structure, the flange of the cylindrical member is exposed on the upper surface of the bottom of the bowl, and a step is generated between the upper surface of the bowl bottom and the flange, so that water always exists in the step. In the presence of water at all times, bacteria propagated and molds propagated and became soiled and adhered, and the appearance was poor and hygienic.
JP 09-268623 A (Specifications 0020, 0021, FIG. 2)

  The present invention relates to a drainage structure for a bowl, and by providing a drain plug directly at the drain outlet at the bottom of the bowl so that it can be raised and lowered, water is not always present at the drain outlet at the bottom of the bowl, and bacteria are propagated. An object of the present invention is to provide a drainage structure for a bowl in which mold does not grow and become dirty.

  In order to solve the above problems, a drainage structure for a bowl according to the present invention is configured such that a drain tube part at a lower end opening is integrally suspended from a drain port part at the bottom of a bowl body to constitute a bowl, and the drain cylinder of the bowl A connecting fitting for connecting a drain pipe is coupled to the lower end opening of the unit, and a drain plug is provided at the drain port of the bowl so as to be movable up and down.

  In the drainage structure of the bowl according to claim 1, a bowl is formed by integrally forming a drain tube part at a lower end opening from a drain port part at the bottom of the bowl main body, and is formed at the lower end opening part of the drain cylinder part of the bowl. Connects a fitting for connecting the drainage pipe and a drain plug to the bowl drainage port so that it can be raised and lowered, and connects the fitting for connecting the drainage port at the bottom of the bowl and the drainage pipe. By separating the parts, water is not always present at the drain outlet at the bottom of the bowl. For this reason, even if a drain plug is provided at the drain outlet of the bowl, the connecting fitting joins the connecting fitting for connecting the drain pipe to the lower end opening of the drain cylinder of the bowl. There is always no water in the part.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of an embodiment of a vanity using the bowl drainage structure according to the present invention. In FIG. 1, 1 is a mirror, 2 is a bowl used for washing, 3 is a cabinet, 4 is a lighting fixture. 2 is a sectional view of the bottom of the bowl 2, and FIG.

  The bottom of the bowl 2 is integrally formed with a drain tube portion 7 having a lower end opening 6 that is suspended from the drain port portion 5. Connecting fittings 9 and 10 for connecting the drainage pipe 8 are coupled to the lower end opening 6 of the drainage cylinder portion 7 that is integrally suspended. The connecting metal fitting 9 is a cylindrical member, and is provided with a flange 11 at the upper end portion and a male screw portion 12 at the lower end portion. The connection fitting 10 is formed with a female screw portion 13 on the inner surface and screwed into a male screw portion 12 at the lower end of the connection fitting 9, and the lower end opening 6 of the drainage cylinder portion 7 is connected to the flange 11 and the connection fitting 10 via the packing 14. It is connected and fixed by being sandwiched between. Reference numeral 15 denotes a drain plug provided in the drain port portion 5.

  In this drainage structure of the bowl 2, a drain plug 15 is provided at the drain outlet 5 at the bottom of the bowl 2 so as to be movable up and down, but connecting fittings 9 and 10 for connecting the drain pipe 8 are provided at the drain outlet 5. The drain port 5 is always provided with the lower end opening 6 of the drain tube 7 formed integrally with the drain tube 7 of the lower end opening 6 from the drain port 5, so that water always exists in the drain port 5. It does not become a state to do. For this purpose, bacteria are not propagated in the drainage port portion 5 and mold is propagated so that dirt does not adhere.

  Naturally, a conventional hair catcher may be provided in the drain plug 15 provided in the drain port portion 5, and further, the drain plug 15 may be operated by a pull rod. It is. The bottom of the bowl 2 is integrally formed with a drain tube portion 7 with a lower end opening 6 hanging down from the drain port portion 5. A drain plug 15 is provided at the drain port portion 5. In order to connect the drainage pipe 8 with 10, water does not always exist in the drainage port 5 at the bottom of the bowl 2.

  The bowl 2 is specifically made of synthetic resin or ceramics. The synthetic resin is suitable for FRP. The bowl 2 is formed by integrally hanging a drain tube portion 7 having a lower end opening 6 from the drain port portion 5 at the bottom of the bowl body, and the drain tube portion 7 is formed at the drain port portion 5 at the bottom of the bowl body. It includes the case where it hangs down by being integrally fixed to the substrate.

The perspective view of the Example of the vanity using the drainage structure of the bowl concerning this invention. FIG. 2 is an explanatory cross-sectional view of a main part of the embodiment shown in FIG. 1. The principal part expansion explanatory drawing of the Example shown in FIG.
