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.

Flush toilet

A flush toilet in which a comparatively large storage region that stores a functional unit can be formed in a region in more rear side than a bowl of a toilet main body, while improving designability of the whole flush toilet is provided. A toilet main body of a flush toilet includes a skirt and a rear function storage portion, the skirt includes an opening, the opening being formed in a portion of an upper part of an outer wall of the skirt, the opening allowing the rear function storage portion inside the skirt to open toward outside the skirt, and a part of the functional unit stored in the rear function storage portion forms an outer surface to close the opening.

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.

A flush toilet includes a toilet main body made of ceramics and a control unit. The toilet main body includes a skirt, and a rear storage that can store at least a part of the control unit, the rear storage includes a supporting wall that divides a storage region into upper and lower regions and that supports the control unit, the skirt forms a double wall including an outer wall and an inner wall, the double wall has at least a part that forms an internal space between the outer wall and the inner wall, and the skirt includes a single wall in which the internal space of the double wall is removed in an upper end above a joining portion between the double wall and the supporting wall.

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.

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.

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.

A switching mechanism is configured to switch an advancing direction of water injected from a nozzle by moving between a first position and a second position. The switching mechanism is held at the second position by a force received from the water injected by the nozzle during the tank water feeding process. A refill mechanism has a refill pipe for causing the water injected from the nozzle during the tank water feeding process and whose advancing direction is switched by the switching mechanism to flow in through an inflow port on one end side. The refill pipe is configured to lead the water having flowed in through the inflow port to a toilet stool body without flowing through a suction port of a throat pipe.
