Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a trap for a drain fitting of a sink or washbasin.

Conventional technology and its problems In general, a trap is a device that stores water in a part of the drainage system, allowing water to flow freely but preventing air and sewage gas from passing through. The latter includes a drum trap (a type that supplies sewage from the bottom of the drum and discharges it from the water surface).
It has been known.

On the other hand, the hairdressing basin is equipped with a drain fitting, and its drain pipe is equipped with a P-trap. The drainage fitting is composed of a dish-shaped strainer, a stopper, a basket-shaped strainer, and the like.

However, although such conventional hairdressing basins are equipped with P-traps to prevent the backflow of sewage gas as described above, a large amount of hair accumulates in the basket-shaped strainer that constitutes the drain fitting, causing hair to be washed away by the person washing the hair. There was an inconvenience in that when people brought their faces close to their hair, they could smell the strange odor, which made the person washing their hair uncomfortable.

Means for Solving the Problems The present invention was devised with a focus on resolving these inconveniences, namely, simply attaching a simple drum trap to the basket-shaped strainer of the sink tank or washbasin drain fitting. This is an attempt to prevent unpleasant odors from accumulating in the basket-shaped strainer by using an inexpensive means of attaching the strainer in a removable manner.

Hereinafter, the configuration of the present invention will be explained in detail with reference to embodiments shown in the attached drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a barber basin main body, and a drain fitting 2 is attached to the center of the bottom thereof. That is, the barber basin main body 1 is held between an external flange 4 projecting outward from the cylindrical drain fitting main body 3 and a fastening fitting 5 that is removably screwed onto the drain fitting main body 3. .

A dish-shaped strainer 6 is removably placed in the upper opening of the drain fitting main body 3 from above, and then a strainer is suspended and fixed to a gripping rod 7 that passes through the center of the dish-shaped strainer 6. The plug 8 is removably fitted into the fitting part 39 formed inside the drain fitting main body 3, and then a plug with a diameter of 50 mmφ and a depth is attached to the internal flange 10 projecting inside the drain fitting main body 3. 82mm
A basket-shaped strainer 11 made of a wire mesh or a perforated plate is suspended, and a fitting joint 17 for a drain pipe is provided at the lower end of the drain fitting main body 3. The above configuration is the drain fitting 2 of a well-known barber basin,
In this embodiment, the following drum trap 12 is attached to the known drainage fitting 2 without making any changes.

That is, a stainless steel hopper body 13 is placed on the upper opening of the basket-shaped strainer 11, a horizontal bar 14 is fixed to the lower opening of the hopper body 13, and a plate is suspended from the horizontal bar 14 with bolts 15. The shaped drum 16 is fixed. The dish-shaped drum 16 has a depth
The preferred size for the basket-shaped strainer 11 is 12 mm and a diameter of 42 mm. With the lower opening of the hopper body 3 protruding into the dish drum 16, the dish drum 16 is fixed. Therefore, if the hair is washed by lifting the gripping rod 7 as shown by the two-dot chain line in the figure, the hair flowing down during the washing will collect in the basket-shaped strainer 11 and will not flow into the sewer pipe. Note that water accumulates in the dish-shaped drum 16 of the drum trap 12 due to the running water. Next, even when the next person washing his/her hair approaches the discharge fitting 13 to wash his/her hair, the basket-shaped strainer 11 and the washbasin body 1 are separated from the drum trap 12.
Since the basket-shaped strainer 11 is partitioned by a partition, the foreign odor of the hair accumulated in the basket-shaped strainer 11 is isolated, and the person washing the hair does not feel uncomfortable.

It should be noted that since the basket-shaped strainer 11 is supposed to be cleaned when about half the amount of hair has accumulated, the hanging position of the drum trap 12 of the present invention is set at the depth of the basket-shaped strainer 11 from above. Since the amount is about 1/3, there is no problem in draining the hair washing water. Furthermore, although this embodiment has been described with respect to a drain fitting for a hairdressing basin, the present invention is not limited thereto, and can also be applied to a basket-shaped strainer of a drain fitting for a think tank, and when applied to such a drain fitting for a think tank, If a so-called bell trap is provided below the drain fitting, the present invention has the advantage that such a bell trap is not necessary and can prevent foul odors from accumulating in the basket-shaped strainer.

In summary, since the present invention adopts the structure described in the claims for utility model registration, it has the following effects.

Effects of the invention: A drum trap is attached to the inside of the basket-shaped strainer of the drain fitting of the sink tank or washbasin, so that the odor caused by the accumulation inside the basket-shaped strainer does not rise above the sink tank or washbasin, causing discomfort to the user. I won't give it. In addition, since the drum trap can be attached to the internal tread space of the basket-type strainer and added to the existing drainage fitting without changing its structure, it can be made inexpensive while still having benefits.
