Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drain trap used for an indoor bathroom, a waterproof pan and the like.

[0002]

2. Description of the Related Art Conventionally, a drainage device has been used in an indoor bathroom, a waterproof pan used for a washing machine, and the like, for draining wastewater generated by using equipment to a sewage side. Among these drainage devices, a drainage device having a function of preventing odors, pests, and the like from the sewage side from going back inside the drainage device and entering the indoor side is particularly called a drainage trap. There are various types of drain traps. As shown in FIG. 11, for example, as shown in FIG. 11, waste water is collected in a part of a drain passage formed therein. Hereinafter, "water sealing", and a portion forming the water sealing is hereinafter referred to as "water sealing portion"), and a drain trap for preventing odor and pests from going back in the water sealing portion is generally used.

[0003]

By the way, in order for the above-mentioned water-sealing portion to sufficiently fulfill the functions of deodorization and insect repellency, it is necessary to form the water-sealing portion, from the lower end of the deodorization cylinder member to the upper end of the deodorization bowl portion. In this case, the depth of the portion forming the water seal (hereinafter referred to as "water depth") must be set to a sufficient depth, and this portion must always be filled with the water seal. In order to achieve this, for example, Japanese Industrial Standards (JIS) specifies that the depth of the water seal in the drain trap is “50 mm or more and 100 mm or less”, and the drain trap normally used in bathrooms and the like. The water depth is also in compliance with this value.

However, when these drain traps are actually used, the water level in the water sealing portion of the drain trap becomes lower than the lower end of the tubular portion of the deodorizing tubular member, thereby impairing the deodorant and insect repellent functions of the drain trap. A phenomenon called "breaking" may occur. There are various causes of rupture, but the most frequent of these is that when drainage is discharged from the outlet of a drain trap, air is drawn into the drainage and the siphon action is a pull-in phenomenon caused by a change in air pressure. Is generated, and the waste water is discharged from the discharge port to the sewage side more than necessary, and the remaining waste water is too small to form a sealed water.

Further, as shown in FIG. 12, a drainage device having no trap function called a drainage elbow is connected to a conventionally used drainage trap, and drainage from the drainage elbow is connected to a branch pipe section. In many cases, the trapping function is added to the drainage elbow by flowing the water into the deodorizing bowl portion through the airbag. However, in this case, a further problem occurs. In this case, the drainage elbow forms a water-sealing portion having a water-sealing depth from the upper end of the drainage flow channel formed inside the branch pipe portion to the upper edge of the deodorizing bowl portion. Here, if the upper end of the branch pipe section and the lower end of the tubular body of the deodorizing tubular member are at the same height, the water sealing depth of both is the same depth, and the deodorant and insect repellent functions of the drainage elbow are provided on the trap body side. And almost the same performance. However, in reality, the upper end of the branch pipe portion is often higher than the lower end of the cylindrical portion, as shown in FIG. 12, due to the functional configuration and shape of the drain trap,
To that extent, the water sealing depth is shallower on the drain elbow side than on the trap body side. by this,

[0004] The puncture phenomenon described above tends to occur more easily than the trap body side, and when the water depth of the trap body is set to a value close to the conformity value such as the industrial standard, the water depth of the drainage elbow is reduced. Becomes shallower than the value specified by the industrial standard or the like, and it becomes impossible to obtain the certification of the industrial standard or the like.

The above problem can be solved by a simple shape change such as lowering the position of the branch pipe section as shown in FIG. 13, for example. In the construction of multi-family housing, etc., the mainstream idea is to reduce the piping space under the floor as much as possible, and to increase the living space accordingly, and accordingly, downsizing of each member, especially downsizing in the vertical direction Is required. In view of this, the above-described solution in which the size is increased in the vertical direction by the height of the branch pipe portion cannot be said to be a practically employable solution. The present invention has been made in view of the above problems, and 1) when draining water from a drain trap or a drain elbow,
Even if the drainage is drawn by the siphon effect, it is necessary to ensure sufficient water sealing. 2) In the drain trap to which the drain elbow is connected, a sufficient sealing depth on the drain elbow side is ensured. 3) The above 1) and 2) are achieved without increasing the vertical width of the drain trap. It is intended to provide a drain trap capable of achieving the above object.
