Description

  TECHNICAL FIELD The present invention relates to a drainage structure in an apron mounting portion to a bathtub in which water that has entered from the washing area side flows between the flange portion of the bathtub and the upper end portion of the apron to the floor side for the washing area of the floor pan. .

  Conventionally, an apron is attached in order to hide the side surface of the bathtub in the washing area (see, for example, Patent Document 1).

  In the above Patent Document 1, when attaching the apron 10, as shown in FIG. 5, a downward projecting portion 6 a is vertically provided on the lower surface side of the distal end portion of the flange portion 6 of the bathtub 2, and the downward projecting portion 6 a A plurality of piece-like elastic bodies 31 are attached at regular intervals in a direction along the washing area on the back side, a rib 32 is provided on the upper end portion of the side surface of the bathtub 2, and a lock provided on the upper end portion of the apron 10 toward the back. The part 30 is inserted into the gap between the rib 32 provided at the upper end of the side surface of the bathtub 2 and the elastic body 31, and the lower horizontal piece 33 protruding toward the back at the lower end of the apron 10 is provided. The apron 10 is attached by placing it on the upper surface of the bank 5 provided at the boundary between the washing floor 4 of the floor pan 1 and the bathtub installation floor 3.

  However, in the conventional example shown in FIG. 6, water flows from the gap between the upper end portion of the apron 10 and the downward projecting portion 6a hanging from the tip portion of the flange portion as shown by the arrow H in FIG. When entering, it passes between the piece-like elastic body 31 and the piece-like elastic body 31, and flows downward from the tip of the locking portion 30 at the upper end of the apron 10 as shown by the arrow in FIG. If there is momentum in the water, it flows further toward the side of the bathtub 2). However, since the tip of the locking portion 30 at the upper end of the apron 10 is shifted to the bathtub 2 side with respect to the bank portion 5, all the flowing water flows to the bathtub installation floor 3 of the floor pan 1. Become. Further, in the above conventional example, even if the tip of the locking portion 30 at the upper end of the apron 10 is located immediately above the bank portion 5, the water that has flowed down from the tip of the locking portion 30 remains. It flows on the lower horizontal piece 33 of the apron 10 placed on the upper surface of the floor, and flows from the tip of the lower horizontal piece 33 to the bathtub installation floor 3 of the floor pan 1.

  Thus, conventionally, water that has entered from the gap between the upper end portion of the apron 10 and the downward projecting portion 6 a of the front end portion of the flange portion 6 flows into the bathtub installation floor portion 3 of the floor pan 1.

However, since the floor portion 3 for installing the bathtub of the floor pan 1 is separated from the washing place side by the bank portion 5 and the apron 10, the floor portion 3 for installing the bathtub of the floor pan 1 cannot be easily cleaned from the washing place side. Therefore, the water that has entered from the gap between the upper end portion of the apron 10 and the downward projecting portion 6a of the tip portion of the flange portion 6 flows into the bathtub installation floor portion 3 of the floor pan 1 so that the floor pan 1 There was a problem that “slimming” and “mold” occurred on the bathtub installation floor 3 and this was not preferable for hygiene.
Japanese Patent Laid-Open No. 2002-336151

  The present invention has been invented in view of the above-described conventional problems, and water that has entered from between the front end of the flange and the upper end of the apron does not flow down to the floor for installing a bathtub in a floor pan. Drainage in the apron attachment part to the bathtub that can be surely flow down to the floor for the washing place and can suppress the occurrence of “slimming” and “mold” due to the ingress of water into the floor for bathtub installation of the floor pan It is an object to provide a structure.

  In order to solve the above-mentioned problem, the drainage structure in the apron attachment portion to the bathtub according to the present invention is at the boundary between the bathtub installation floor portion 3 where the bathtub 2 of the floor pan 1 is installed and the washing floor portion 4 serving as a washing place. A ridge 5 is provided, and a water return protrusion 7 is provided along the washing area on the lower surface of the flange 6 adjacent to the washing area of the bathtub 2 installed on the bathtub installation floor 3 of the floor pan 1. An upper support 8 is provided at a position shifted from the water return projection 7 toward the tip of the flange 6, a lower support 9 is provided on the bank 5, and the lower end of the water return 7 is connected to the bank The upper attachment portion 11 provided at the upper part on the back side of the apron 10 is attached to the upper support 8 and is located on the lower side on the back side of the apron 10. The lower attachment portion 12 provided on the upper portion is attached to the lower support 9 and the apron 10 is removed. The lower end of the apron 10 at only condition is characterized in that comprising in opposition through a contact or a small gap 13 on the side surface of the washing area side of the bank portion 5.

  By adopting such a configuration, the water that has entered from between the front end of the flange 6 and the upper end of the apron 10 can be further infiltrated by the water return protrusion 7 provided on the lower surface of the flange 6. It is blocked and flows downward from the lower end of the water return projection 7. Here, since the lower end of the water return protrusion 7 is shifted from the end of the upper surface of the bank 5 toward the washing area, the water flowing down from the lower end of the water return protrusion 7 Does not flow on the washing floor 4 or the dam part 5 but flows to a position shifted to the washing basin side of the upper surface of the dam part 5 from the washing part side, and the washing part side of the dam part 5 at the lower end of the apron 10 It flows out to the floor part 4 for washrooms from between the side surfaces.

  Further, it is preferable that a small protrusion rib 14 is provided on the side surface on the washing area side of the water return protrusion 7 and the back end of the upper end of the apron 10 is brought into contact with the small protrusion rib 14.

  When a person enters or exits the bathtub 2, or when the bathtub 2 expands or contracts by sinking deeply or by sinking the body shallowly, the upper end of the apron 10 extends over the entire length of the water return projection 7 2, the contact resistance is large, so there is a risk of noise. However, as described above, the small protrusion rib 14 is provided on the side surface on the washing field side of the water return protrusion 7. By abutting the back end portion of the upper end portion of the apron 10 to the rib 14, a point contact is made, and the contact resistance is small, and the noise due to the expansion and contraction of the bathtub 2 can be prevented.

  In the present invention, as described above, the lower end of the water return protrusion is positioned so as to be shifted to the washing area side from the end on the washing area side of the upper surface of the bank, and the apron upper mounting part is attached to the upper support and the apron. The lower attachment part is attached to the lower support, and the apron is attached with the lower end of the apron in contact with the side surface of the washing section side of the bank or through a small gap. Water that has entered from between the upper end is prevented from entering further by the water return protrusion, and flows downward from the lower end of the water return protrusion to the side of the washing basin side of the bank at the lower end of the apron. It will flow to the floor for the washing room from the middle, and it can be easily cleaned even if the washing floor side gets dirty with the water that has flowed down. As a result, it entered from between the front end of the flange part and the upper end of the apron. Water does not flow down to the bathtub installation floor The bathtub installed for the floor portion side it is possible to suppress the occurrence of the "slime" and "mold" by the ingress of water, which is hygienic.

It fits by pushing into the receiving part 9a of the lower support 9 provided in the upper surface part from the washing place side. The apron 10 is attached in this manner. In this attached state of the apron 10, the lower end of the apron 10 is brought into contact with the side surface of the bank 5 on the washing place side or through a small gap 13, as shown in FIG. It comes to oppose. In addition, the apron 10 is set so that the entire apron 10 is shifted from the side surface of the dam portion 5 on the washing place side to the washing place side with the apron 10 attached.

  If the water enters between the lower end of the downward projecting portion 6a of the front end portion of the flange portion 6 on the washing place side of the bathtub 2 and the upper end of the apron 10 as indicated by an arrow A in FIG. The water return protrusion 7 provided on the lower surface of the portion 6 prevents water from entering further, and flows downward from the lower end of the water return protrusion 7 as shown by the arrow B in FIG.

  Here, in the present invention, since the lower end of the water return protrusion 7 is shifted from the end of the upper surface of the bank portion 5 on the washing field side, the water return protrusion 7 is positioned. The water flowing downward from the lower end does not flow on the bathtub installation floor 3 or the bank 5, but flows to a position shifted to the washing area from the end of the washing area on the upper surface of the bank 5 and the apron 10. The lower horizontal piece that flows to the center or lower part of the back surface, flows downward along the back surface of the apron 10 as shown by the arrow C in FIG. 18 flows from the front end of the bank 5 to the washing floor 4 as shown by the arrow D in FIG.

  Thus, the water that has entered from between the front end of the flange 6 and the upper end of the apron 10 flows out to the washing floor 4 and does not flow to the upper surface of the bathtub installation floor 3 or the bank 5. Therefore, it is possible to prevent the occurrence of “slimming” and “mold” by the water that has entered the upper surface of the bathtub installation floor 3 and the bank 5. On the other hand, the water that has flowed from the lower end of the apron 10 to the side of the washing place side of the bank 5 to the washing floor 4 is drained from the washing floor 4 to the drain provided in the washing floor 4. However, the water flowing from the lower end of the apron 10 and the side of the levee 5 on the side of the washing place to the washing place floor 4 causes “slimming” and “mold” to occur on the washing place floor 4 side. Even if there is something wrong, it is on the side of the washing place, so it can be cleaned easily to remove “slimy” and “mold” and clean it.

  Further, the small protrusion rib 14 on the side surface on the washing place side of the water return protrusion 7 of the present invention is mounted on the top side by pressing the tip of the upper horizontal piece 15 on the rear side upper end of the apron 10 as described above. It serves as a positioning member for fitting the hole 11a which is the portion 11 into the protruding shaft portion 8a of the upper support 8, but the tip of the upper horizontal piece 15 is only in point contact with the small protrusion rib 14. Therefore, it is possible to reduce the contact resistance and prevent the squeaking caused by the expansion and contraction of the bathtub 2.
