摘要： A flush toilet includes a rear storage configured to store a control unit of a toilet main body. The rear storage includes a supporting wall configured to support the control unit so as to divide a storage region of the rear storage into upper and lower regions. In a rear supporting region of the rear storage, a first distance in a horizontal left-right direction from an outer joining portion to an inner joining portion in the supporting wall is shorter than a second distance in the horizontal left-right direction from an outer wall in the double wall of the skirt to an inner joining portion of the supporting wall. The second distance is set to a maximum width dimension in the left-right direction in an internal space of the double wall of the skirt.

摘要： A flush toilet includes a toilet main body made of ceramics, a control unit, a supply source that enables water supply or power supply to the control unit, and a flexible elongated member connecting the supply source and the control unit. The toilet main body includes a rear storage configured to store at least a part of the control unit. The rear storage includes an upper storage region, a lower region, and a lower communication region. The flexible elongated member extends from an upper connecting end portion toward a lower connecting end portion, to be inserted from the upper storage region into the lower communication region, and then extends from inside of the lower communication region to outside of the toilet main body, without extending through the lower region.

摘要： A flush toilet of the present invention includes: a bowl including a waste receiving surface, a rim and a shelf surface, the shelf surface of the bowl including linear portions formed on a right side and a left side, a front arc portion connected to front ends of the linear portions, and a rear arc portion connected to rear ends of the linear portions; a rim spout portion spouting flush water to the shelf surface to form a circulating flow; and the like. Flush water is spouted backward from the rim spout port along the linear portions of the shelf surface; and the shelf surface and the waste receiving surface are coupled by an inner coupling portion, and a curvature radius of the inner coupling portion along a vertical direction is set to a smaller value on a rear end of the bowl than on a front end thereof.

摘要： A flush toilet is capable of suppressing water from splashing from a bowl at a time when water is discharged rearward inside the bowl from one rim spout port portion formed in a rim portion. A rim spout portion of the flush toilet forms a rim water passage where flush water that is supplied flows through, and forms, on a downstream end of the rim water passage, a rim spout port portion that discharges the flush water rearward. The rim spout port portion, which is one in number, is formed in the rim portion, and the rim spout port portion in the linear portion is formed to discharge water rearward in the bowl in a direction extending the linear portion.

摘要： A flush toilet which is capable of suppressing reduction in the force of water and disturbance in the flow curved by a pressure loss caused by a flow curved separating from a surface on an inner side portion side of an intermediate part. A rim water passage of the flush toilet includes a curved portion that is curved inward from a downstream end of an outer side portion. The curved portion includes a top portion that is at a position farthest from the intermediate part in the top view, in a direction extending the intermediate part. The top portion is formed in more the outer side portion side than a virtual center line that extends along a center of the intermediate part.

摘要： A flush toilet includes a toilet main body and a control unit. The toilet main body includes a skirt, a rear storage configured to store at least a part of the control unit, and an opening to which a drain pipe is connected is formed penetrating, in a front-rear direction, a portion below a center in a left-right direction of a rear wall of the skirt. The rear storage forms a discharge socket storage on a front side of the opening in a region below a center of the rear storage in the left-right direction. And a side wall surface in the discharge socket storage protrudes more in a center direction of the opening than a side wall surface in the opening, to reduce an opening cross-sectional area of the discharge socket storage to be smaller than an opening cross-sectional area of the opening.

摘要： A flush toilet includes a toilet main body made of ceramics and a rear storage configured to store at least a part of a control unit. The rear storage includes a supporting wall that divides a storage region into upper and lower regions and that joins left and right side walls of the skirt and the water discharge trap. The supporting wall includes a horizontal wall that extends in a horizontal direction from a joining portion between the supporting wall and the water discharge trap, and left and right lower walls that are provided outside the horizontal wall in a left-right direction and below the horizontal wall and that are joined to the left and right side walls of the skirt. The left and right lower walls on a rear side are separated in the left-right direction by the horizontal wall.

摘要： A flush toilet includes a toilet main body made of ceramics including a skirt and a rear storage configured to store at least a part of a control unit. The skirt includes a rear wall and a side wall provided in a back surface and a side surface of the toilet main body, respectively. The rear wall includes an opening provided between a peripheral edge of each opening and the side wall of the skirt. The opening penetrates in a front-rear direction to communicate between an inner region of the rear storage or an outer region below the inner region and an outer region behind the toilet main body. The skirt further includes a cross beam that joinably or coupleably supports the peripheral edge of the opening and the side wall of the skirt to each other so as to reinforce strength of the toilet main body.
