Abstract

PURPOSE:To execute the water sealing at the outlet of a bathtub, to prevent the counter flow of bad smell, and also, to facilitate the cleaning by attaching a drain metallic fixture so that it can be connected to a drain pipe, dropping a bowl trap into this drain metallic fixture and detaining it. CONSTITUTION:At the time of draining hot water of a bathtub, when a drain plug 7 is drawn out, hot water in the bathtub is led into an inner trap from inside of a drain metallic fixture 4, flows down to a drain pipe 6 through a drain port 8 of an outer trap from the inner trap and drained. Subsequently, after the drain is completed, a part of the drain is stored in a position being lower than the drain port 83 in the outer trap, and the lower end of the inner trap is subjected to water sealing. Accordingly, it is prevented that air in the drain pipe executes a counter flow into the bathtub. Also, at the time of cleaning the trap, after the plug is opened, cleaning can be executed by drawing out both the inner and the outer traps from inside of the drain metallic fixture.

The odor coming from the sewer is blocked out by a box placed outside the bathtub. [Problem to be solved by the invention] Even if a basin is provided in the middle of the drainage channel between the bathtub and the sewer pipe, water scale and other organic matter adhere to the interior of the drainage channel, and the inside of this drainage channel cannot be cleaned. Therefore, it is impossible to block the odor generated in the drainage canal from the basin to the bathtub drain. Furthermore, if hair, towel waste, etc. flow out of the bathtub into a narrow drainage channel, they may get caught in the drainage channel and cause the drain to become clogged or become narrow.

[Means for Solving Problem 1] The present invention has been made to achieve the above object. A drain fitting is attached to the drain port of the bathtub so that it can be connected to a drain pipe, and a bowl trap is dropped into the drain fitting. The gist is to lock it.

づいて説明する。The bowl trap is installed so that it falls into the drain fitting installed in the bathtub drain, so when draining water, you can drain it in the same way as before by pulling out the drain plug, and you can also leave it in the plug state after draining. The action of the bowl trap at the bathtub drain completely blocks off the drain pipe or drainage channel leading to the bath, so bad odors will not flow back into the bathroom from the drain pipe or drainage channel. Additionally, this bowl trap can be dropped into the drainage fitting and locked, making it easy to clean. [Example] The drain structure of the bathtub according to the present invention will be described below based on the illustrated example.

も低い位置とする。The drain port 2 is constructed by fixing a drain fitting 4 to a hole 3 drilled in the bathtub l using a clamping fitting 5. This drainage fitting 4
has a flange 4l larger than the diameter of the bathtub hole 30 on the inner end side, and has an outer diameter so as to be inserted into the hole 3, and has a male thread 42 carved therein, and using this male thread 42, the nut-shaped The supporting fitting 5 is screwed on to support the periphery of the hole 3 of the bathtub and to securely secure the bathtub. Note that the drain pipe 6 is connected to the outer end shank portion 43 of the drain fitting 4, and the drain fitting 4 is also connected to the drain pipe 6.
When fixed to the bathtub l in cooperation with the supporting metal fittings 5, packing is used as necessary to prevent water leakage from the gaps between the bathtub hole 3 and the metal fittings 4 and 5. Further, the drain fitting 4 has a drain plug 7 removably fitted therein, and locking steps 44 and 4δ are formed with different diameters on the inner circumferential surface below the drain plug fitting position. ．． The two upper and lower locking steps 44 and 45 are used to lock the bowl trap 8 that is dropped into the drain fitting.
This bowl trap 8 consists of an outer trap 8A and an inner trap 8B.
2 is fixed to the locking step 45 on the lower side of the drain fitting, and a plurality of drain ports 83 are bored on the outer circumferential surface. It shall be set at a required height position from the bottom part 84 of the main body so that a part of it is always stored. In addition, the inner trap 8B is fitted into the main body 8l of the outer trap 8A, and is integrally provided with a locking collar 86 at the upper end of a short-shaped main body 85 that is shorter than the zero body 8l. is locked to the locking stage 44 on the upper stage side. At this time, a gap necessary for drainage is formed between the lower end of the inner trap and the inner bottom surface of the outer trap, and this gap is located at a position lower than the drain port 83.

利点を有する．In the drain structure configured as described above, when draining hot water from the bathtub, when the drain plug 7 is pulled out as in the conventional case, the hot water in the bathtub is guided from the drain fitting 4 into the inner trap, and the water flows through the inner trap. The water then flows down to the drain pipe 6 through the drain port 83 of the outer trap and is drained. After draining is completed, a portion of the waste water is stored in the outer trap at a position lower than the drain port 83, and the lower end of the inner trap is sealed with water to prevent the air in the drain pipe from flowing back into the bathtub. This will prevent this from happening. Also, when cleaning the trap, after opening the trap,
Both the inner and outer traps can be pulled out and cleaned from inside the drain fitting. [Effects of the Invention] The drain port structure of the bathtub of the present invention is such that a drain fitting is attached to the drain port of the bathtub so that it can be connected to a drain pipe, and a bowl trap is dropped into the drain fitting and locked. It has the advantages of being able to seal the water at the outlet of the bathtub, reliably preventing the backflow of bad odors, and being a simple device that can be installed without changing the existing drainage channel and being easy to clean.
