Description

  The present invention relates to a blindfold plate provided in a drain outlet, such as a washstand and a sink.

  Conventionally, for household appliances that generate drainage when used, such as washstands and sinks (hereinafter these devices are referred to as “drainage devices”), the wastewater generated in the tank is discharged from the piping under the floor to the sewage side. A drainage device having a drain outlet is provided on the bottom of the tank body. The drainage outlets of these drainage devices are simply open holes, so that, for example, as seen in many sinks, the drainage outlets are equipped with eye plates and garbage baskets, etc. There are various things, such as those that are devised so as not to flow into the drain pipe and cause clogging or water pollution.

In the above drainage outlet, the user feels uncomfortable when looking directly at the slime substances and deposits in the drainage outlet, and when the drainage outlet is equipped with garbage baskets, the filth and scum in the garbage baskets. In many cases, a blindfold plate is provided at the drainage port so as not to look directly into the garbage basket or the like in the mouth or the drainage port.
FIG. 6 shows an example of such a blindfold plate, in which a step portion is provided at the periphery of the drain outlet of the sink, and a peripheral portion that rises perpendicularly in a sectional view is placed on the step portion, thereby the blind plate at the drain port. Arranged.
Further, the blindfold plate has a covering formed on the inner side of the peripheral portion, a flat portion whose one half is slightly inclined toward the center, and a slope portion whose other half is greatly inclined downward. It is provided with a portion, and drainage is performed smoothly, and functions so that wrinkles and slimes in the drain outlet are not directly viewed.

JP-A-8-177101 (FIGS. 3 and 4)

  Although the blindfold plate as described in the above paragraph 0003 usually has a slight gap (margin) for easy attachment / detachment with respect to the step portion of the drainage port, the peripheral edge of the blindfold plate for the purpose of improving the design. The outer peripheral surface of the portion and the inner peripheral surface of the step portion of the drain outlet are formed in substantially the same shape / size. For this reason, when sand, wrinkles, hair, etc. mixed in the wastewater enter between the outer peripheral surface of the peripheral edge portion of the blindfold plate and the inner peripheral surface of the step portion of the drainage port, the blindfold plate and the drainage port described above There was a problem that the gap between the two was filled and the blindfold plate could not be removed from the drain.

Conventionally, most of the blindfold plates are made of a resin material. In this way, if the blindfold plate is a resin material, there is some flexibility in material, so even if you bite sand etc. between the gap between the blindfold plate and the drain port, by pulling the blindfold plate slightly forcibly, Although the surface was slightly scratched, the blindfold plate was bent and could be taken out from the drain outlet.
However, recently, the case where the blindfold plate is made of a metal material such as stainless steel is increasing. This is because when a large amount of drainage is flowed, the blindfold plate rises from the drainage outlet if the resin material has a specific gravity close to that of the water. These sinks are often made of a metal material such as stainless steel, for reasons such as matching color tones and addressing design issues such as high-quality effects. However, a metal material is much stronger than a resin and does not bend like a resin. Also, because the drain outlet is often made of inflexible material such as metal or ceramics, if sand or the like is caught between the blindfold plate and the drain outlet, the drain outlet or the blindfold plate will be scratched or damaged. It was necessary to pull up the blindfold plate forcibly or to remove the sand that had entered the gap while taking time and effort with a brush.
The present invention has been invented to solve the above-described problems. In the blindfolded plate of the drainage port, the blindfolded plate, particularly in the blindfolded plate made of a metal material, between the blindfolded plate and the drainage port. It is an object of the present invention to provide a drainage blindfold plate that is easy and does not cause scratches or breakage when removing the blindfold plate even when sand or the like is bitten.

According to claim 1 of the present invention, a blindfold plate for covering the drain outlet of the bottom surface of the tank body,
A drainage blindfolding plate characterized by comprising: a step provided at the periphery of the drain outlet; and a peripheral edge that is mounted on the step and is inclined toward the center of the drain outlet downward. .

  According to claim 2 of the present invention, the drainage blindfold plate according to claim 1 is made of a metal material.

  According to claim 3 of the present invention, there is provided a concealed plate for a drain outlet according to claim 1, characterized in that it is covered with a resin material and a metal material.

According to the piping structure of the drainage device of the present invention, the following effects are obtained.
According to the drainage device of the tank body according to claim 1, the outer peripheral surface of the peripheral portion of the blindfold plate and the inner peripheral surface of the step portion of the drain port are formed in substantially the same shape / dimension for the purpose of improving the design. If there is sand, wrinkles or hair mixed in the drainage between the outer peripheral surface of the peripheral edge of the blindfold plate and the inner peripheral surface of the stepped portion of the drainage port, the gap between the blindfold plate and the drainage port Since the gap is wide, there is an effect that it is hardly buried.
This functions particularly effectively when the whole or part of the blindfold plate is made of a metal material like the blindfold plate of the drain outlet according to claims 2 and 3.
