DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit having a floor surface having a water gradient in a bathroom, and a drain groove formed in the floor surface along a direction intersecting the direction of the water gradient of the floor surface. It relates to a waterproof pan for a bath washing area.

[0002]

2. Description of the Related Art Conventionally, a waterproof pan for a washing area of a unit bath has a water gradient for draining water on a floor surface when a person in a bathroom works with bare feet, while a person works with bare feet. In order to prevent the water from slipping easily, a large number of drain grooves for quickly draining the water are provided along a direction intersecting the water gradient direction. Usually, the floor surface is formed with a rough surface to the extent that a person does not slip easily.

[0003]

According to the construction of the conventional washing pan waterproof pan described above, the water dropped on the floor surface flows down along the water gradient, flows into the drain groove, and flows into the drain groove. Therefore, since the water flows toward the periphery of the floor portion, it is adopted for the purpose of preventing water from staying in a portion of the floor portion where a person works with bare feet. In some cases, water may remain as water droplets and not drain well before the water flows down and flows into the drainage groove, and the top surface of the floor surface may be rough. Tends to remain in the form of a film without flowing down as water droplets. Therefore, even though the drainage groove is provided to achieve good drainage, there is a possibility that the drainage groove may not function sufficiently, which may cause the worker to slip easily. There was a case.

Accordingly, an object of the present invention is to eliminate the above-mentioned disadvantages.

[0005]

A feature of the present invention to achieve the above object is to provide a bathroom having a floor surface having a water gradient in a bathroom and extending along a direction intersecting the water gradient direction of the floor surface. A drain groove is provided on the floor surface, and an adjacent upper surface portion along the drain groove on the upstream side in the water gradient direction of the drain groove is formed to be smoother than other portions. -The effects are as follows.

[Operation and Effect] That is, when water flows into the drain groove, the water flows from the upstream side in the water gradient direction so as to fall into the drain groove. Here, when the floor surface on the upstream side in the water gradient direction of the drain groove is formed as a rough surface, when the amount of falling water decreases, the moving speed in the water gradient direction decreases, and intermittently. There is a tendency to drop in the form of droplets. Then, water on the floor surface which is about to fall from the edge of the drainage groove acts as a force to stay on the floor surface having a rough surface tension. For this reason, once the water that is going to flow into the drain groove is collected in a liquid layer, it is difficult to generate droplets, and water remains on the floor surface in a relatively thick liquid layer state (water drainage). Is bad) (see FIG. 6B). On the other hand, the smoother the surface condition of the floor is, the more difficult it is for the moving speed of the water in the direction of the water gradient to decrease, so that the water flows so as to fall into the drain groove until it becomes a relatively thin liquid film. It's easy to do. For this reason, the water remaining on the floor surface is formed in a liquid film by forming the floor position on the upstream side in the water gradient direction of the drain groove in which the water film is likely to be formed near the drain groove in a smooth surface. The shape can be extremely reduced. By the way, there is a rough surface portion and a smooth surface portion on the floor surface, and the flowing water flows into the rough surface portion (rough surface portion).
When moving from the surface to the smooth surface part (smooth surface part), it seems that a liquid layer is also formed and the drainage becomes poor, but in such a case, the moving speed of the falling water in the direction of the water gradient is reduced. Even if it is lowered, the water that has moved to the smooth surface is less likely to be in the form of droplets, and the water remaining on the rough surface is more likely to be a relatively thin water film than in the previous state, and the amount of remaining water can be extremely reduced. It becomes like that. More specifically, although the water that moves from the rough surface to the smooth surface eventually moves in the form of droplets, the moving direction is likely to match the moving direction on the rough surface, and Since the frictional force with the floor surface is reduced, the water that is going to be droplets starts to move at a high speed. Therefore, the water that is going to become droplets flows down while pulling in the water of the rough surface portion.As a result, the water does not become completely droplets, but easily flows in a river shape. The flow velocity of the water on the rough surface portion is not easily reduced, and the flow of the river-like water guides the water to the smooth surface portion until the water on the rough surface portion is almost exhausted. As a result, the drainage of the washing basin waterproofing pan on the floor surface becomes extremely good, and it is possible to prevent inconveniences such as people becoming slippery and unstable on the washing basin, becoming unsightly due to remaining water, and becoming hard to dry, and a bathroom. To help you use comfortably.
