Description

  The present invention relates to a drainage socket structure of a flush toilet, and in particular, an inlet end of a drainage pipe provided at a position higher than a floor surface branched from a vertical drainage pipe installed in a vertical direction in a wall surface or a toilet and a flush toilet The present invention relates to a drainage socket structure for a flush toilet that communicates with an outlet end of a drainage channel of a main body.

Conventionally, in order to connect the drainage channel of the flush toilet to the drainage pipeline on the wall surface, a drainage socket is known in which the height of the drainage socket relative to the pedestal portion can be adjusted with a screw (Patent Document 1).
In addition, in order to connect the drainage channel of the flush toilet to the drainage line on the floor, the drainage socket is inverted with respect to the flushing toilet so that it can be adjusted to the drainage line on the floor provided at a different position. A drain socket is known (Patent Document 2).

JP-A-2005-48407 Patent 3089535

However, although the drain socket described in Patent Document 1 is excellent in that one socket can correspond to various drain core heights, there is room for improvement in that the height adjusting means becomes complicated.
Moreover, in the drainage socket described in Patent Document 2, the drainage channel facing downward is directly connected to the drainage pipeline on the floor surface, and the channel is greatly different because the entire drainage socket is inverted. It is difficult to ensure the discharge performance at the two drainage pipe installation positions, and the configuration in which the entire drainage socket is inverted cannot be connected to the drainage pipe provided on the wall surface.

  The present invention has been made to solve the above-mentioned problems of the prior art, and provides a drainage socket structure for a flush toilet that can be easily positioned to the drainage pipe located on the side of the flush toilet. The purpose is to do.

  In order to achieve the above object, the present invention provides a drainage socket for a flush toilet that allows the outlet end of the drainage channel of the flush toilet body to communicate with the inlet end of a drainage pipe provided on the wall surface at a position higher than the floor surface.

  According to the present invention, it is possible to easily position the drainage pipe located on the side of the flush toilet.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
First, the arrangement and configuration of the drainage socket structure of the flush toilet according to the first embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is an overall longitudinal sectional view showing a flush toilet and a wall drain pipe to which a drain socket structure of a flush toilet according to a first embodiment of the present invention is applied, and FIG. 2 is a first embodiment of the present invention. It is a longitudinal cross-sectional view in the case of being in the 1st position of the drainage socket structure of the flush toilet bowl by a form, and FIG. 3 is the case of being in the 2nd position of the drainage socket structure of the flush toilet bowl by 1st Embodiment of this invention. It is a longitudinal cross-sectional view.

  First, as shown in FIG. 1, the flush toilet body 2 of the flush toilet 1 is fixed on the floor surface F, and a pipe D for discharging the drainage of the flush toilet body 2 to the wall W is provided. Is provided. The distance (drainage core height) from the floor surface F to the center of the pipe line D has various heights at the site where the toilet is constructed, and varies between 90 and 155 mm, for example. In this embodiment, a structure suitable for construction sites having a drainage core height of 120 mm and 155 mm will be described.

  The flush toilet body 2 includes a bowl part 4, an inlet pipe 6 extending obliquely upward from the bottom of the bowl part 4, a drainage path communicating with the inlet pipe 6 and extending downward and opening vertically downward. 8 and an outlet end 10 of the drainage channel 8. In this way, the flush toilet body can be applied to both wall drainage and floor drainage by making the outlet end open vertically downward so that the toilet body can be shared. Is desirable. And the drain socket 20 by embodiment of this invention is provided so that this exit end part 10 and the pipe line D may be connected. The drain socket 20 is made of a plastic material such as vinyl chloride.

  As shown in FIGS. 2 and 3, the drain socket 20 includes a drain socket body 22, a cylindrical inlet portion 24 provided above the drain socket body 22 and opened vertically upward, horizontally from the vertical direction. A flow path 26 that bends in a direction perpendicular to the direction and a cylindrical outflow port 28 that is provided on the side of the drain socket body 22 and opens in the horizontal direction. A rubber packing 30 is attached to the inlet portion 24 between the outlet end portion 10 and the inlet portion 24. Thus, the outlet end 10 of the toilet drainage channel 8 is inserted and connected to the inflow port 24 via the rubber packing 30.

  Next, a support portion 32 for supporting the drain socket body 22 on the floor surface F is attached to the drain socket body 22. In the case of the present embodiment, it is formed integrally with the drain socket 22. The support portion 32 includes a first portion 32a directly attached to the drain socket body 22, a second portion 32b formed below the first portion 32a and having a radial dimension larger than that of the first portion 32a, and a bolt or the like on the floor F. And a pedestal portion 32c provided for fixing. The first portion 32a, the second portion 32b, and the pedestal portion 32c are integrally molded.

The drain port attaching part 40 is connected to the first cylindrical part (inlet part) 40a connected to the outlet part 28 of the drain socket body 22 and the drain pipe D and is opened in the horizontal direction. It has two cylindrical parts (outlet part) 40b. The horizontal axis B of the second cylindrical portion 40b of the drain port mounting portion 40 is eccentric with respect to the outlet 28 of the drain socket body 22 and the horizontal axis A of the first cylindrical portion 40a, and the drain port mounting portion 40. Is attached to the drain socket body 22 so as to be rotatable around the horizontal axis A of the outlet portion 28 of the drain socket body 22.

  Therefore, by rotating the drain port mounting portion 40, the drain core height of the second cylindrical portion 40b of the drain port mounting portion is set to the lower position (120 mm in this embodiment) and the upper position (155 mm in this embodiment). It can be adjusted in two stages. In particular, the flow path configuration of the drain toward the wall surface W is important in terms of the performance of the flush toilet, and the drain socket body 22 and the drain port mounting portion 40 are provided to ensure the performance. That is, while the flow path is continuous from the drain socket main body 22 to the drain port mounting portion 40, even when the drain core height is different, the drain port mounting portion 40 is rotated to achieve drainage performance even at different heights. Can be secured.
