Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a drain trap for a sink sink. More specifically, the present invention relates to a drain trap for a sink sink in which a water pipe can be directly connected to an under-floor water pipe without displacement.
[0002]
[Prior art]
In FIG. 7, like the drain trap for the sink sink of JP-A-2001-3429, the sink (21) is being studied for securing the capacity of the storage portion (21a) below the sink (22). ing. For that purpose, the drainage trap (23) located below the sink (22) and the drainage pipe (29) are the key. That is, if the drain trap (23) can be downsized and the drain pipe (29) can be disposed on the back side of the sink (21), the capacity of the storage portion (21a) such as a drawer can be increased.
[0003]
However, with respect to the former, regarding the sealing portion (25) including the rising pipe portion (27) and the deodorizer (28), the upper end (27a) of the rising pipe portion (27) to the lower end (28a of the deodorizer (28). There is a provision in the Building Standards Act that the sealed water depth is 50 mm or more. Moreover, if the capacity | capacitance of garbage containers (26), such as a net basket, is reduced, the collection amount of garbage etc. will fall. Therefore, the downsizing of the drain trap (23) is naturally limited.
In order to make the latter possible, it is considered to arrange the drain port (22a) on the sink (22) side. However, that alone is insufficient, and a device for arranging the drain pipe (29) itself on the back side of the sink (21) is required.
[0004]
Therefore, as a drain trap for the sink sink suitable for securing the capacity of the storage portion below the sink of the sink while maintaining the deodorizing performance, as shown in FIG. 8, the drain trap for the sink sink (31), A part of the bottom surface of the drain trap body is formed by the upper surface (32a) of the drain pipe connecting pipe portion (32) facing the side of the drain trap body, and this is provided with the deodorizer (34 ) Near the lower end (34a). And the front-end | tip part of this drainage pipe connection pipe part (32) is used as the diameter expansion part (32b) which expanded upward and expanded the opening diameter, and the front-end | tip protrudes sideways from the side part of a drain trap main body. There is something that let me. And the length of a front-end | tip part (34a) can be shortened to the length which can be fixed with connection fixing tools (33), such as a hose nut. This is effective in setting the position of the drain outlet in the sink as far as possible. Moreover, if the front-end | tip of a drain pipe (34) can be inserted in the diameter expansion part (32b) of a drain pipe connection pipe part (32), the positioning at the time of connecting a drain pipe (34) will become easy. That is, the connection position of the drain pipe (34) is determined by inserting the tip of the drain pipe (34) until it contacts the drain pipe connecting pipe section (32) at the end of the enlarged diameter section (32b). Therefore, the operator can confirm this with a sense at hand, and positioning becomes easy.
[0005]
In this way, the drain trap for the sink sink is suitable for securing the capacity of the storage section below the sink of the sink while maintaining the dust storage performance, but at the lower end of the drain pipe (34) When connecting to a drainage pipe under the floor with a single drainage connection port, it is common to use a bellows pipe for vertical alignment and leave the extra bellows pipe in the storage. It was.
[0006]
[Problems to be solved by the invention]
The present invention aims to solve the above-mentioned problems, and is suitable for securing the capacity of the storage section under the sink of the sink while maintaining the deodorizing performance, and is arranged under the floor without using a bellows tube. A drain trap for a sink sink that can be easily connected to a water pipe is provided.
[0007]
[Means for Solving the Problems]
The drain trap for a sink sink according to claim 1 of the present invention has a waste container storage part at the upper part of the drain trap body, a sealing part at the lower part of the drain trap body, and the sealing part from the bottom part of the drain trap body.

Disposed from the central axis of the container storage part, one end flows at the lower end of the rising pipe part of the sealing part, the first drain pipe connection part is provided in the vertical direction by shifting the central axis to the front side of the stand, and the other end Is characterized in that a second drain pipe connecting portion is provided in the horizontal direction toward the back side of the sink .
[0008]
Therefore, it is suitable for securing the capacity of the storage part under the sink of the sink while maintaining the deodorizing performance, and by providing two drain pipe connection parts, it is possible to connect to the underfloor water pipe without using a bellows pipe. A drainage trap for a sink sink that can be easily connected can be obtained.
[0009]
The drain trap for a sink sink according to claim 2 of the present invention is such that the distance between the central axis of the drain trap according to claim 1 and the central axis of the first drain pipe connecting portion is X, A 90 ° elbow is connected to form a third drainage pipe connection portion below, and the distance between the central axis of the drainage trap and the central axis of the third drainage pipe connection portion is Y, and the relationship is approximately Y = 2X. 1. A third drain pipe connecting portion is provided. [0010]
Therefore, while maintaining the deodorizing performance, the distance between the central axis of the drain trap and the central axis of the third drain pipe connection portion is Y, and the first and third drain pipe connection portions are arranged in a relationship of approximately Y = 2X. Since the third drain pipe connection part can be arranged on the back side, it is possible to secure the capacity of the storage part below the sink of the sink, and without using a bellows pipe, Connection to the is easy.
[0011]
A drain trap for a sink sink according to claim 3 of the present invention comprises a straight pipe portion at the upper and lower ends of either the first drain pipe connection portion or the third drain pipe connection portion according to claim 1 or claim 2. The upper end of a rotatable water distribution pipe provided with an inclined portion in the middle is connected and the lower end is connected to an underfloor water distribution pipe.
[0012]
Therefore, even if the installation position of the underfloor water distribution pipe is slightly deviated, the positioning can be easily performed by rotating and positioning the water distribution pipe. At this time, one drain pipe connecting portion is closed so as not to be drained by the cap.
