The width LA of the flange 61A of the first side wall 61 is larger than the width LB of the flange 62A of the second side wall 62. The width LB of the flange 62A of the second side wall 62 is equal to the width LC of the flange 63A of the third side wall 63 and the width LD of the flange 64A of the fourth side wall 64.

  The inner surface of the first corner 60A, which is a portion connecting the second side wall 62 and the third side wall 63, has an angle DA toward the center side of the bathtub space SA from the opening 50A of the bathtub 50 toward the bottom wall 51. (See FIG. 5) and the angle DB (see FIG. 5) are inclined more rapidly. The inner surface of the second corner 60B, which is a portion connecting the second side wall 62 and the fourth side wall 64, has an angle DA toward the center side of the bathtub space SA from the opening 50A of the bathtub 50 toward the bottom wall 51. (See FIG. 5) and the angle DB (see FIG. 5) are inclined more rapidly. Therefore, as shown in FIG. 7, when the bathtub 50 is installed in the installation unit 23, the maintenance space SB is between the corner 23 </ b> A of the installation unit 23 where the first corner 60 </ b> A is arranged and the bathtub 50. It is formed. Moreover, although not shown in figure, when the bathtub 50 is installed in the installation part 23, between the corner 23B (refer FIG. 2) and the bathtub 50 of the installation part 23 in which the 2nd corner 60B (refer FIG. 4) is arrange | positioned. A similar maintenance space SB is formed.

  The installation portion 23 that forms the bottom of the maintenance space SB includes a part of the floor drain port 24. The drain lid 30 to which the floor drain port 24 is attached has an opening 31 at a position facing the drain port 52 of the bathtub 50 and a position where the filter port 32 is exposed from the outer surface of the bathtub 50, that is, the maintenance space SB. It is attached to the floor drain 24 so as to be arranged. Although not shown, the opening 31 of the drain lid 30 is also disposed at a position facing the drain port 52 (see FIG. 2) of the bathtub 50, and the filter port 32 is disposed at a position exposed from the outer surface of the bathtub 50. As shown in FIG.

  A filter member 33 is fitted in the filter port 32. As for the filter member 33, a filter (not shown) is disposed below the floor drain port 24. The upper surface of the filter member 33 is provided with a gripping portion 33A that can be put on by the operator when performing maintenance. Further, an opening 33B is formed on the upper surface of the filter member 33 to guide the drainage leaked to the upper surface of the installation portion 23 to the drain trap 41 (see FIG. 3) through a filter (not shown).

  As shown in FIG. 4, the opening / closing device 70 includes a plurality of plug lids 71 that open and close the drain ports 52 and 53, a plurality of wires 72 that are connected to the respective plug lids 71, and a plurality of wires 72. A plurality of operation units 73 connected to each other are provided.

  As shown in FIG. 8, the opening / closing device 70 is a so-called push-up type drain plug, the wire 72 is pulled by operating the operation unit 73, and the plug lid 71 is pulled by pulling the wire 72. The drain ports 52 and 53 are opened. As shown in FIG. 4, the operation portion 73 is attached to the intermediate portion 61 </ b> B of the flange 61 </ b> A of the first side wall 61.

The drainage structure of the bathroom 10 has the following actions and effects.
(1) In the bathtub 50, a plurality of drainage ports 52 and 53 that open to the bathtub space SA are formed in the bottom wall 51. For this reason, compared with the case where there is one drain outlet, drainage capacity can be improved. For this reason, it can contribute to shortening the time which drainage requires.

  (2) When the user enters the bathtub 50, there is a low possibility that the user puts his / her feet near the corner of the bathtub 50. Further, when the user is immersed in the bathtub 50 in a sitting position, it is difficult to place the buttocks and feet near the corner in front of the bathtub 50. The first drain port 52 is formed near the third side wall 63 between the third side wall 63 and the fourth side wall 64. The second drainage port 53 is formed near the fourth side wall 64 between the third side wall 63 and the fourth side wall 64. That is, the drain ports 52 and 53 are formed in a place where the foot and the buttocks are difficult to contact when the user bathes. For this reason, a user can reduce the possibility that he / she may come into contact with the stopper lid 71 of the drain ports 52 and 53 and feel uncomfortable at the time of bathing.

  (3) The plurality of drain ports 52 and 53 are formed near the second side wall 62 between the first side wall 61 and the second side wall 62. The outlet of the collecting pipe 43 is located on the front side of the bathtub 50. For this reason, compared with the case where the drain ports 52 and 53 are formed at positions close to the first side wall 61, the drain pipes from the drain ports 52 and 53 to the outlet of the collecting pipe 43 through the floor drain ports 24. The length of the member 40 can be shortened.

  (4) The angle DB formed by the bottom wall 51 and the second side wall 62 is included in the range of 90 to 94 degrees. That is, the second side wall 62 is formed to be substantially perpendicular to the horizontal plane. For this reason, compared with the case where the 2nd side wall 62 inclines gently toward the bottom wall 51 from a top part, a user gets over the 1st side wall 61 and enters the bathtub 50 easily. Also, when the caregiver assists the user in bathing, the second side wall 62 is less likely to hit the second side wall 62 than when the second side wall 62 is gently inclined from the top toward the bottom wall 51. Easy to assist.

  (5) The angle DA formed by the bottom wall 51 and the first side wall 61 is larger than the angle DB. For this reason, at the time of integral molding of the bathtub 50, it is easy to take out the bathtub 50 from the mold as compared with the case where the angle DA is equal to or less than the angle DB.

  (6) The inner surface of the first corner 60A and the inner surface of the second corner 60B are inclined toward the center of the bathtub space SA from the opening of the bathtub 50 toward the bottom wall 51. For this reason, a maintenance space SB is formed above the drain lid 30. For this reason, the surroundings of the floor drain outlet 24 can be confirmed in a state where the bathtub 50 is installed on the floor pan 20. In addition, maintenance of the filter member 33 attached to the drain lid 30 of the floor drain port 24 in a state where the bathtub 50 is installed on the floor pan 20 can be performed.

  (4) When the corners of the side wall 60 are gently formed, the position of the user is likely to be shifted along the side wall 60 when the user immersed in the bathtub 50 deposits his back on the side wall 60. On the other hand, when the corner of the side wall 60 is substantially a right angle, the plane portion near the corner of the side wall 60 supports the scapula on both sides of the user, and the position of the user is difficult to shift.

  The bathtub 50 has a shape in which the inner surfaces of the first side wall 61, the second side wall 62, the third side wall 63, and the fourth side wall 64 are close to a plane. For this reason, the side wall 60 has a rectangular shape in plan view. That is, between the first side wall 61 and the third side wall 63, between the first side wall 61 and the fourth side wall, between the second side wall 62 and the third side wall 63, and second The angle between the side wall 62 and the fourth side wall 64 is substantially a right angle. For this reason, since the plane part near the corner of the side wall 60 tends to support the shoulder blades on both sides of the user, the posture of the user is easily stabilized.

  (5) In a temporary bathtub in which the size of the flange formed on the top of the side wall 60 changes, the narrow portion is easier to grip than the large flange portion. The size of the flange 62A of the second side wall 62 is constant. For this reason, since it becomes easy to grasp a user even if it is any part of flange 62A, the convenience improves. In the intermediate portion 62B, the flange 62A is linearly formed along the planar shape of the second side wall 62. For this reason, compared with the case where the flange 62A is curved, the hand is less likely to be displaced along the flange 62A when the user grips the flange 62A.

  (6) The handrail 12 is attached to the wall panel 11 along which the first side wall 61 extends. Since the width LA of the flange 61A of the first side wall 61 is larger than the width LB of the flange 62A of the second side wall 62, the amount by which the handrail 12 protrudes above the bathtub space SA can be reduced. For this reason, it can suppress that the handrail 12 becomes obstructive at the time of a user's bathing.

  (7) The bathtub 50 includes a plurality of operation portions 73 that are connected to each of the plurality of stopper lids 71 by wires 72 and operate to open and close each of the stopper lids 71. For this reason, each plug lid 71 can be opened and closed individually. For this reason, the user can slowly discharge the water in the bathtub 50 by opening only one of the plug lids 71, for example, when adjusting the amount of water. That is, since the discharge speed of the water in the bathtub 50 can be selected, convenience is improved.

  (8) The floor pan 20 includes a plurality of floor drain ports 24 at portions corresponding to the plurality of drain ports 52 and 53, respectively. For this reason, compared with the structure which collects and drains the waste_water | drain of several drain outlet 52,53 to the one floor drain outlet 24, the drainage performance of the bathtub 50 can further be improved.

  (9) In the drainage structure of the bathroom 10, each of the plurality of drainage ports 52 and 53 and the plurality of floor drainage ports 24 are connected by the connecting member 90. For this reason, when drainage is discharged from drain ports 52 and 53 to floor drain port 24, it can control that drainage diffuses on floor pan 20.

  (10) The ability to drain from the bathroom 10 is affected by the size of the drain trap 41 of the drain pipe member 40. In the drainage structure of the bathroom 10, a drain pipe member 40 is provided for each floor drain port 24, and a drain trap 41 is provided for each drain pipe member 40. For this reason, compared with the case where the drain trap 41 of the same size as the drain trap 41 is provided in the part after collecting the floor drain port 24, the drainage performance after the floor drain port 24 can be improved.

  Further, when the drainage trap 41 is provided with a drainage trap larger than the drainage trap 41 to improve drainage performance, the height of the drainage trap 41 becomes large. Space becomes larger. For this reason, the bathtub 50 is disposed at a relatively high position with respect to the washing place 21. For this reason, it becomes difficult for the user to cross the side wall 60. Since the drainage structure of the bathroom 10 is provided with the drainage trap 41 at each of the floor drainage ports 24, it is possible to achieve both improvement of drainage performance and suppression of enlargement of the drainage trap.

  The concrete form which the drainage structure of a bathroom can take is not limited to the form illustrated by the said embodiment. The drainage structure of the bathroom can take various forms different from the above embodiment. The modification of the said embodiment shown below is an example of the various forms which the drainage structure of a bathroom can take.

  As shown in FIG. 9, the first drain port 52 and the second drain port 53 are located closer to the first side wall 61 and closer to the center between the third side wall 63 and the fourth side wall 64. It can also be formed. When a user enters the bathtub 50, there is a low risk of putting a foot on the wall panel 11 side of the bathtub 50. Moreover, when the user is immersed in the bathtub 50 in a sitting position, it is difficult to place the buttocks and feet near the center of the bathtub 50. That is, the drain ports 52 and 53 are formed in a place where the foot and the buttocks are difficult to contact when the user bathes. For this reason, a user can reduce the possibility that he / she may come into contact with the stopper lid 71 of the drain ports 52 and 53 and feel uncomfortable at the time of bathing. Moreover, since the drain ports 52 and 53 are on the first side wall 61 side on the wall panel 11 side, it is easy for the assistant to perform assistance.

  As shown in FIG. 10, the first drain port 52 is formed near the first side wall 61 and between the third side wall 63 and the fourth side wall 64, near the third side wall 63. You can also. Further, the second drainage port 53 can be formed near the first side wall 61 and between the third side wall 63 and the fourth side wall 64 and near the fourth side wall 64. When a user enters the bathtub 50, there is a low risk of putting a foot on the wall panel 11 side of the bathtub 50. Further, when the user is immersed in the bathtub 50 in a sitting position, it is difficult to place the buttocks and feet near the corners of the bathtub 50. That is, the drain ports 52 and 53 are formed in a place where the foot and the buttocks are difficult to contact when the user bathes. For this reason, a user can reduce the possibility that he / she may come into contact with the stopper lid 71 of the drain ports 52 and 53 and feel uncomfortable at the time of bathing. Moreover, since the drain ports 52 and 53 are on the first side wall 61 side on the wall panel 11 side, it is easy for the assistant to perform assistance.

  The angle DB of the angle formed by the bottom wall and the second side wall 62 can be included in the range of 94 to 96 degrees. Also in this case, since the second side wall 62 is formed so as to be close to a right angle with respect to the horizontal plane, the second side wall 62 is gently inclined from the top toward the bottom wall 51. The user can easily get over the second side wall 62 and enter the bathtub 50.

-Angle DB of the angle which a bottom wall and the 2nd side wall 62 make can also be 96 degrees or more.
-The 1st side wall 61, the 2nd side wall 62, the 3rd side wall 63, and the 4th side wall 64 can also be made into a planar shape. In this case, both ends 61C and 61D of the first side wall 61, both ends 62C and 62D of the second side wall 62, both ends 63C and 63D of the third side wall 63, and both ends 64C of the fourth side wall 64, 64D is not curved.

  -At least 1 of the 1st side wall 61, the 2nd side wall 62, the 3rd side wall 63, and the 4th side wall 64 can also be made into the curved shape. When all of the first side wall 61, the second side wall 62, the third side wall 63, and the fourth side wall 64 are formed in a curved shape, the side wall 60 has an elliptical shape in plan view.

  The opening / closing device 70 can be changed to the opening / closing device 170 shown in FIG. The opening / closing device 170 includes a plurality of plug lids 171 that open and close each of the plurality of drain ports 52, 53, a wire 172 connected to each of the plurality of plug lids 171, and one operation unit 173 connected to the wire 172.
