Description

  The present invention relates to a bathroom floor pan having joint grooves formed in a washing area.

  Conventionally, bathroom floor pans having a concavo-convex pattern in which a large number of joint grooves such as a lattice are intersected on the upper surface of the washing area are used in consideration of design and slipperiness.

  By the way, in the washing area, there is a water gradient that is a downward gradient toward the drainage side. When the direction of the water gradient and the direction in which the joint groove extends intersect, the water gradient of the joint groove is It becomes gentler and dirt is more likely to adhere to the inner surface of the joint groove compared to the joint groove parallel to the water gradient direction in the washing area. For this reason, it is necessary to clean a joint groove that intersects the water gradient in the washing area, but it is difficult to clean the inner surface of the narrow joint groove.

Further, for example, in Patent Document 1, a plurality of convex portions formed on the upper surface of the washing area are provided with micro unevenness to impart hydrophilicity, and the inner surface of the concave portion formed between the convex portions is made to be more than the upper surface of the convex portion. A bathroom floor pan having a high water repellency is disclosed. However, the bathroom floor pan of Patent Document 1 has a problem that the drainage property of the inner surface of the recess is low because the inner surface of the recess has water repellency.

  This invention is made in view of the said conventional problem, Comprising: It aims at providing the bathroom floor pan which can clean easily the joint groove which is easy to become dirty, maintaining the high drainage capacity of the bathroom floor pan. Is.

In order to solve the above problems, a bathroom floor pan according to claim 1 of the present invention has the following configuration. The upper and lower surfaces of the washing area 3 have a concavo-convex pattern formed by intersecting a plurality of joint grooves 5. In each intersection 6 where the plurality of joint grooves 5 intersect, a joint drain groove 7 having the greatest downward gradient among the joint grooves 5 having a downward gradient from the intersection 6 is defined as a main drainage joint groove 7. Further, the other joint groove 5 having a smaller downward slope than this is used as a sub-drain joint groove 8. The subdrain joint groove 8 has water repellency superior to the main drain joint groove 7 . Hydrophilicity is imparted to the main drainage joint grooves 7 and water repellency is imparted to the subdrain joint grooves 8.

  In the present invention, the main drainage drainage groove having a large descending slope is more hydrophilic than the subdrainage drainage channel, so that the high drainage capacity of the bathroom floor pan can be maintained. Further, since the sub-drain joint groove having a small downward slope has water repellency, the sub-drain joint groove can be easily cleaned.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. The bathroom floor pan 1 of the present embodiment shown in FIGS. 1 to 3 is integrally formed of FRP or the like. The bathroom floor pan 1 includes a washing area 3 having a substantially rectangular shape in plan view that is long in the longitudinal direction of the bathtub 2. The washing area 3 constitutes the floor of the washing area adjacent to the bathtub 2. In addition, the bathroom floor pan 1 may be provided with a bathtub installation area for installing the bathtub 2 formed integrally with the washing area 3. Moreover, what was provided with the bathtub formed integrally with the washing area 3 may be used. Further, it may be constituted only by the washing area 3.

  A drainage port 4 having a rectangular shape in plan view is formed at the end of the washing area 3 on the bathtub 2 side and at an intermediate portion in the longitudinal direction of the bathtub 2. The washing area 3 is gradually inclined downward from the end opposite to the bathtub 2 to the end on the bathtub 2 side, and has a water gradient that is downwardly inclined toward the bathtub 2 that is the drainage side. That is, the direction of the water gradient of the washing area 3 indicated by the arrow in FIG. 3 is parallel to the width direction of the washing area 3 having a substantially rectangular shape in plan view (that is, the direction orthogonal to the longitudinal direction of the bathtub 2). The water on the entire upper surface of the region 3 flows smoothly toward the drain port 4 side.

  A number of joint grooves 5 that intersect with each other over the entire surface excluding the drain outlet 4 are formed on the upper surface of the washing area 3 provided with the water gradient in consideration of design and slipperiness. In the illustrated example, the joint groove 5 is a straight vertical joint groove 5a extending in the width direction of the washing area 3 and a straight horizontal joint groove 5b extending in the longitudinal direction of the washing area 3 and orthogonal to the vertical joint groove 5a. Various types of joint grooves 5 are provided.

  A plurality of vertical joint grooves 5 a are provided at regular intervals in the longitudinal direction of the washing area 3, and a plurality of horizontal joint grooves 5 b are also provided at regular intervals in the width direction of the washing area 3. That is, joint grooves 5 having a lattice shape in plan view as a whole are formed on the upper surface of the washing area 3. A portion surrounded by a large number of rectangular frame-shaped joint grooves constituting the lattice-shaped joint grooves 5 is a convex portion 9 that is one step higher than the joint grooves 5, and the lattice-like shape is formed on the upper surface of the washing area 3. An uneven pattern defined by the joint grooves 5 is formed. As a result, the design of the upper surface of the washing area 3 is improved, and the joint groove 5 prevents the foot of a person walking on the washing area 3 from slipping.

  The vertical joint groove 5 a located at the middle part in the longitudinal direction of the washing area 3 and the horizontal joint groove 5 b located at the end of the washing area 3 on the bathtub 2 side are continuous with the drain port 4. Accordingly, all the joint grooves 5 communicate with the drain port 4 and function as drain channels that smoothly guide the water on the washing area 3 to the drain port 4.

  When the vertical joint groove 5a is used as a reference, there are crossing portions 6 that intersect the horizontal joint groove 5b in a cross shape, a T shape, or an L shape at a plurality of locations in the longitudinal direction of each vertical joint groove 5a. Of the two types of joint grooves 5a and 5b, the vertical joint groove 5a extends in parallel with the water gradient direction of the washing area 3 indicated by the arrow in FIG. It becomes a steep groove. Further, since the horizontal joint groove 5b extends in a direction perpendicular to the water gradient direction of the washing area 3 in plan view, the water gradient becomes a gentle groove with respect to the drain port 4 as compared with the vertical joint groove 5a.

  Here, with respect to each intersection 6 provided in the washing area 3, the main drainage joint groove 7 having the largest downward slope among the joint grooves 5 having a downward slope from the intersection 6 in each intersection 6. The other drain with a smaller downward slope is designated as a subdrain joint groove 8. That is, in this embodiment, the vertical joint groove 5a is used as the main drain joint groove 7 and the horizontal joint groove 5b is used as the sub drain joint groove 8.

  A treatment for imparting water repellency is performed on the inner surface composed of both side surfaces and the bottom surface of the sub-drain joint groove 8 connected to each intersection 6. In this embodiment, the cross hatched portions in FIG. 2 and FIG. 3, that is, each side surface and the bottom surface including the intersection portion 6 of each sub drainage joint groove 8 with the main drain joint groove 7. Water repellent treatment is applied to the entire inner surface. Examples of the treatment for imparting water repellency to the inner surface of the sub-drain joint groove 8 include a coating treatment with a water-repellent resin, and embedding in the sub-drain joint groove 8 a material from which water-repellent resin or a water-repellent component bleeds out. Can be mentioned.

  On the other hand, hydrophilicity is imparted to the inner surface of the main drainage joint groove 7 connected to each intersection 6. Examples of the treatment for imparting hydrophilicity include forming fine irregularities on the surface, and applying a hydrophilic coating on the surface.

  The determination of water repellency and hydrophilicity is based on a contact angle of water of 90 degrees. That is, the contact angle of water in the main drain joint groove 7 is 90 degrees or more, more preferably, the contact angle of water in the main drain joint groove 7 is 100 degrees or more. Further, the contact angle of water in the subdrain joint groove 8 is less than 90 degrees, and more preferably, the contact angle of water in the joint drain groove 8 is 70 degrees or less.

  As described above, all the main drainage joint grooves 8, except for the intersection 6 with the subdrain joint groove 8, have higher hydrophilicity than the sub drain joint groove 8. For this reason, the main drainage joint groove 7 is highly drainable, and the water in the main drainage joint groove 7 smoothly flows to the drain outlet 4 side. As a result, the water on the washing area 3 can be drained reliably.

  Moreover, since each subdrain joint groove 8 has a small water gradient as compared with the main drain joint groove 8, dirt is easily attached. However, as described above, the water repellency is imparted to the inner surface of each auxiliary drain joint groove 8 of the present embodiment, so that even if dirt is attached, it can be easily wiped off. That is, the bathroom floor pan 1 of the present embodiment imparts water repellency to each sub-drain joint groove 8 and imparts hydrophilicity to each main drain joint groove 8, thereby increasing the height of the main drain joint groove 7. While maintaining the drainage, the inner surface of the main drainage joint groove 7 which is more easily soiled than the main drainage joint groove 7 can be easily cleaned.

  In the above embodiment, the water repellency is imparted to the intersection 6 of the sub drainage joint groove 8 with the main drainage joint groove 7. However, the intersection 6 may not be provided with the water repellency. Hydrophilicity may be imparted to the. Further, in this embodiment, the main drainage joint groove 7 is provided with hydrophilicity and the secondary drainage joint groove 8 is provided with water repellency. Water repellency may be imparted only to the ditches 8, or hydrophilicity may be imparted only to the main drainage joint grooves 7, and water repellency may be imparted to the subdrain joint grooves 8, that is, the subdrain joint grooves. It is sufficient if 8 has water repellency superior to the main drain joint groove 7.

  In the above embodiment, the gradient direction of the water gradient in the washing area 3 is parallel to the width direction of the washing area 3. However, a water gradient toward the drain port 4 may be provided in each part of the washing area 3. That is, in this case, the gradient direction of the portion on the opposite side of the bathtub 2 from the drain outlet 4 of the washing area 3 includes a directional component parallel to the width direction of the washing area 3, and the washing area in the longitudinal direction of the washing area 3 The gradient direction of the part located on both outer sides of the drain outlet 4 in the region 3 includes a directional component parallel to the longitudinal direction of the washing area 3. Therefore, the gradient direction of the water gradient in each part of the washing area 3 is different.

  Therefore, in the case where the direction of the water gradient is changed in each part of the washing area 3 as described above, for example, a lattice-shaped joint groove 5 including a plurality of vertical joint grooves 5a and horizontal joint grooves 5b is provided as in the above embodiment. In this case, depending on the position of the washing area 3, the water gradient with respect to the drainage port 4 of the horizontal joint groove 5 b is steeper than the water gradient with respect to the drainage port 4 of the vertical joint groove 5 a that intersects the horizontal joint groove 5 b at the intersection 6. It will be a thing. Therefore, in this portion, the horizontal drainage groove 5b is used as the main drainage joint groove 7, and the vertical joint groove 5a intersecting with the auxiliary drainage joint groove 8 at the intersection 6 is used as the secondary drainage joint groove 8. If water repellency is imparted to the inner surface of the joint groove 8, the same effect as in the above embodiment can be obtained.

It is explanatory drawing which showed the water-repellent process part by cross hatching in the washing-room floor part same as the above. It is a plane view explanatory drawing which showed the water-repellent treatment part of the washing-room floor part same as the above by cross hatching.
