Description

The present invention relates to floor panels and bathroom units.

Conventionally, in order to improve the drainage performance of the floor surface of a washing area, the floor surface is inclined toward the drain port. For example, in a washing area floor as described in Patent Document 1, the floor is divided along a ridge line, and each floor is inclined at various slopes. In this way, by dividing the floor surface into a plurality of sections and sloping them at different slopes, it is possible to effectively guide the flow of water toward the drain port.

Japanese Patent Application Publication No. 2016-065391

Even if the floor surface is sloped, many small water droplets remain on the floor surface without being drained away. If the slope is made too steep in order to reduce residual water, the footing will become unstable during use, making it impossible to use it comfortably.

The present inventors have discovered that residual water can be reduced by draining water continuously without interrupting the flow of water droplets on the floor surface, and have completed the present invention.

The present invention relates to a floor panel constituting the floor of a bathroom washroom provided with a drainage section, and which includes a first inclined surface section that slopes downward toward the drainage section; To provide a floor panel having a drainage speed control part whose drainage speed is lower than that of a slope part.

<First embodiment>
The bathroom unit 100 includes a rectangular floor structure 1, a shower 2, a faucet 3, a bathtub 4, and a counter 5. Further, the floor structure 1 includes three floor panels 10 and a drainage section 14, and a straight valley-shaped ridgeline 12 is formed between the floor panels 10. The three floor panels 10 are inclined so that water flows toward the drainage portion 14 (in the direction of the arrow in FIG. 2), and have good drainage performance. The floor panel 10 includes a first slope section 11 and a drainage speed control section 13 around the drainage section 14 .

In the drainage speed control section 13, the means for controlling the drainage speed is not particularly limited. In this embodiment, the drainage speed control section 13 is configured to be inclined so that water flows toward the drainage section 14 with a smaller slope than the first inclined surface section 11 which is the other part of the floor panel 10. This is the second inclined surface portion. As a result, the speed at which the drainage water flows on the drainage speed control section 13 is lower than that on the first inclined surface section 11 .

The range in which the drainage speed control section 13 is formed varies depending on the slope and area of the washing area floor. As will be described later, there is no particular limitation as long as the upstream water droplets catch up with the downstream water droplets and unite the water droplets flowing on the floor surface without interruption, thereby improving drainage performance.

The drain section 14 is formed in a concave shape in the floor surface 1, and drains water after use through a drain port provided inside. The drainage part 14 is covered with a lid, and water flowing on the surface of the inclined floor panel 10 flows into the gap between the floor panel 10 and the lid and is drained. The upper surface of the lid has an appearance unified with the surface of the floor panel 10 and forms part of the floor structure 1. This improves the design while maintaining drainage performance.

The drainage part 14 is arranged on the bathtub 4 side of the floor structure 1. Although the arrangement of the drainage section 14 is not particularly limited, it is preferably arranged on the side far from the entrance of the bathroom. If a drain is placed where users pass through when entering the room, where dirty water, hair, etc. collect after washing, the cleanliness will be degraded, and it will cause unpleasant odors and other discomfort to the users. This is to make it happen.

A and A' in FIG. 3 indicate cross sections taken along line A-A' in FIG. 2. In the drainage speed control section 13, the speed at which water droplets flow on its surface is slower than that of the first inclined surface section 11. In other words, while the water droplets flowing on the surface of the floor panel 10 slow down around the drainage part 14, the water droplets flowing on the surface of the first inclined surface part 11 further upstream flow at a high speed, so that the water droplets flowing downstream are decelerated. We will have to catch up. In this way, water flowing from upstream catches up with and merges with the water droplets flowing through the granules.

In the conventional floor structure 01 shown in FIG. 4, the floor panel 010 does not have a drainage speed control section. That is, the water droplets continue to accelerate due to the inclination and flow into the drainage section 014. At this time, since the speed of the water droplet is higher downstream, if the speed difference becomes large, the upstream water droplet and the downstream water droplet will be interrupted. Most of the water droplets head directly to the drainage section 014 as downstream water droplets, but the remaining upstream water droplets may remain.

This is thought to be because the upstream water droplets are small and light, and the gravitational force acting on them is small, so they stay in place due to the effects of friction with the floor and surface tension.

Returning to FIG. 3, in the floor panel 10 according to the floor structure 1 of the present invention, the drainage speed of water droplets is lower downstream than upstream, so the upstream water droplets catch up with the downstream water droplets and become integrated. becomes less likely to break due to the speed difference between upstream and downstream. Since the water droplets integrated on the drainage speed control section 13 have a large weight, they flow to the drainage section 14 without staying in the drainage speed control section 13 even if the drainage speed is small. Therefore, it is possible to reduce residual water on the floor surface, especially in the upstream section.

Compared to the conventional floor structure, the water droplets are slowed down and retained in the drainage speed control unit 13, so that the water droplets can be connected upstream of the floor panel 10 as one unit. The combined water droplets draw in the upstream portion by causing the downstream portion to flow into the drainage section 14 . Therefore, water can be drained even further upstream.

As mentioned above, according to the floor panel 10 of this embodiment, the following effects are produced.

(1) The floor panel 10 of the present embodiment is a floor panel 10 that constitutes the floor surface of a bathroom washing area provided with a drainage section 14, and includes a first inclined surface section 11 that slopes downward toward the drainage section 14; The floor panel 10 includes a drainage speed control section 13 that is provided around the drainage section 14 and has a drainage speed lower than that of the first inclined surface section 11.

As a result, the drainage speed of water droplets is lower downstream than upstream, so the upstream water droplets catch up with the downstream water droplets and become one, draining the water droplets without interruption, reducing residual water on the floor. At the same time, water can be drained further upstream.

(2) In (1), the drainage speed control section 13 is a second slope section that slopes downward toward the drainage section with a smaller slope than the first slope section.

Thereby, the drainage speed control unit 13 can suppress the drainage speed of water droplets, and the drainage performance is improved.

(3) The bathroom unit 100 of this embodiment includes the floor panel 10 of (1).

Thereby, the bathroom unit 100 has excellent drainage performance.

The embodiment of the bathroom unit of the present invention is not limited to a type in which a bathtub 4 and a shower are integrated as shown in FIG. Good too.

<Second embodiment>
Next, a floor structure 21 according to a second embodiment of the present invention will be described. The floor panel 20 according to the floor structure 21 differs from the floor panel 10 according to the first embodiment in the configuration of the drainage speed control section 13.

FIG. 5 shows a cross section along a straight line spanning the two first slope portions 21 across the drainage portion 214, corresponding to AA′ in FIG. In the floor panel 20 of the floor structure 21 , the surface of the drainage speed control section 213 is more hydrophilic than the first inclined surface section 211 . That is, since water droplets tend to remain on the drainage speed control section 213, the drainage speed of the water droplets flowing on the drainage speed control section 213 becomes slow.

According to the floor panel 210 of this embodiment, the following effects are achieved.

(4) In (1), the drainage speed control section 213 is formed to be more hydrophilic than the first inclined surface section 211.

Thereby, the drainage speed control unit 213 can suppress the drainage speed of water droplets, and as in the floor structure 1 according to the first embodiment, the drainage speed of water droplets is lower downstream than upstream, so that Not only can residual water be reduced, but water can also be drained further upstream.

The embodiments according to the present invention have been described above. The present invention is not limited to the above-described embodiments, and the present invention also includes improvements and changes thereof. For example, the control means in the drainage speed control section is not particularly limited, and the coefficient of friction may be adjusted by adjusting the unevenness of the floor surface, or by a combination of slope and hydrophilicity.
