Description

  The present invention relates to a splash water preventer for a Western-style flush toilet.

  As a conventional splash water preventer for a Western-style flush toilet, as shown in FIGS. 10 to 12, a heart-shaped sponge or non-woven mat having a size capable of floating on the pool water 102 of the flush toilet 100 ( A main body portion 103 is known, which has a structure in which a fragrance 105 is filled in a central concave portion 104 thereof, and activated carbon 107 is filled in concave portions 106 in several places on the outer periphery (see, for example, Patent Document 1). .

Utility model registration No. 3016225

However, the conventional splash proof device for a Western flush toilet has the following problems.
That is, the main body 103 of the conventional example has a heart shape and has a plate shape without a through hole. Therefore, even if the stool falls on the main body 103, the main body 103 does not turn over. It will remain in touch. Therefore, the smell of the stool diffuses outside, and the inside of the toilet becomes odorous.

  In addition, the concave portion 104 that stores the fragrance 105 and the three concave portions 106 that store the activated carbon 107 are formed on one surface of the main body 103 so that the weight balance in the front and back direction of the main body 103 is increased. Since it is in a collapsed state, the main body 103 is more difficult to rotate.

Further, when the amount of the fragrance 105 is decreased, a depression is formed in the central portion of the main body 103, and stool tends to adhere and remain in the depression.
Further, since the outer peripheral surface of the main body 103 is formed on a plane orthogonal to both the front and back surfaces of the main body 103, it is difficult for water to get on the upper surface side of the main body 103, so It tends to remain attached.

  Moreover, in the gazette of the conventional example, even after draining, the main body 103 is not swept away by buoyancy. However, in condominiums and the like, due to the difference in atmospheric pressure between indoors and outdoors on windy days Since the pool water 102 in the flush toilet 100 may be sucked out and lost, it is not possible to prevent the main body 103 from flowing out only by having buoyancy. In the conventional example, the size of the main body 103 is not specified at all, and is extremely small even when viewed from the drawing (FIG. 12). When the stool is on the outer peripheral side, the stool falls directly on the pooled water 102 without falling on the main body 103, and therefore it is impossible to prevent the water from bouncing back.

  The problem to be solved by the present invention is that it is possible to surely prevent the water from splashing and to surely prevent the water from flowing out of the drain outlet, and to smoothly and repeatedly invert the water in the reservoir water.
