Abstract

A toilet device is configured to be capable of performing toilet seat reverse face washing, in which a cleaning liquid is supplied onto a reverse face of a toilet seat and the reverse face is washed. When the toilet seat is placed in a non-closed state, the toilet device does not perform the toilet seat reverse face washing.

Claims (44)

1 . A toilet device configured to be capable of performing toilet seat reverse face washing, in which a cleaning liquid is supplied onto a reverse face of a toilet seat and the reverse face is washed, wherein

when the toilet seat is placed in a non-closed state, the toilet seat reverse face washing is not performed.

2 . The toilet device of claim 1 , comprising a control unit that controls the toilet seat reverse face washing, wherein

when the toilet seat is placed in a non-closed state, the control unit does not allow the toilet seat reverse face washing to be performed.

3 . The toilet device of claim 2 , further comprising a human detecting sensor that detects a user, wherein

upon detection of a user by the human detecting sensor during toilet seat reverse face washing, the control unit stops the toilet seat reverse face washing.

4 . The toilet device of claim 2 , further comprising a sitting detecting sensor that detects sitting of a user on the toilet seat, wherein

upon detection of sitting of a user on the toilet seat by the sitting detecting sensor during toilet seat reverse face washing, the control unit stops the toilet seat reverse face washing.

5 . The toilet device of claim 2 , further comprising an opening and closing detecting sensor that detects open and closed states of the toilet seat, wherein

upon detection of the toilet seat placed in a non-closed state during toilet seat reverse face washing, the control unit stops the toilet seat reverse face washing.

6 . The toilet device of claim 1 , further comprising a biasing device that biases the toilet seat in a closing direction during toilet seat reverse face washing.

7 . The toilet device of claim 6 , wherein

the biasing device is a motor used to open and close the toilet seat, and

during toilet seat reverse face washing, the control unit rotates a rotating shaft of the motor in a rotating direction in which the rotating shaft is rotated to close the toilet seat.

8 . The toilet device of claim 1 , further comprising a lock mechanism that locks the toilet seat in the closed state during toilet seat reverse face washing.

9 . A toilet seat unit configured to be capable of performing toilet seat reverse face washing, in which a cleaning liquid is supplied onto a reverse face of the toilet seat unit and the reverse face is washed, wherein

when the toilet seat unit is placed in a non-closed state, the toilet seat reverse face washing is not performed.

10 . The toilet device of claim 1 , comprising:

a toilet body including a toilet bowl;

a seal member that is sandwiched between the toilet body and the toilet seat when the toilet seat is placed in the closed state; and

a pressing mechanism that presses the toilet seat onto the toilet body.

11 . The toilet device of claim 10 , wherein

the seal member is formed into a ring shape, and

the seal member is sandwiched between the toilet body and the toilet seat over the entire circumference when the toilet seat is placed in the closed state.

12 . The toilet device of claim 10 , wherein the pressing mechanism comprises a motor used to open and close the toilet seat and presses the toilet seat onto the toilet body by continuously rotating a motor shaft of the motor in a rotating direction in which the motor shaft is rotated to close the toilet seat.

13 . The toilet device of claim 10 , wherein the pressing mechanism comprises a lock mechanism that locks the toilet seat in the state of being pressed onto the toilet body.

14 . The toilet device of claim 10 , wherein

the toilet body includes an outer side upper surface, and an inner side upper surface positioned on the inner side and the lower side with respect to the outer side upper surface, and

the seal member is provided between the inner side upper surface and the toilet seat.

15 . The toilet device of claim 10 , further comprising a toilet seat reverse face washing mechanism that supplies a cleaning liquid onto the reverse face of the toilet seat to wash the reverse face, wherein

the pressing mechanism presses the toilet seat onto the toilet body while at least one of the toilet body or the reverse face of the toilet seat is washed.

16 . The toilet device of claim 1 , comprising a drying device that dries the reverse face of the toilet seat, wherein

the drying device performs drying of the reverse face of the toilet seat when the toilet seat is placed in a closed state.

17 . The toilet device of claim 16 , further comprising:

a toilet body including a toilet bowl;

a seal member that is sandwiched between the toilet body and the toilet seat when the toilet seat is placed in the closed state; and

a pressing mechanism that presses the toilet seat onto the toilet body while the drying device dries the reverse face of the toilet seat.

18 . The toilet device of claim 17 , wherein

the seal member is formed into a ring shape, and

the seal member is sandwiched between the toilet body and the toilet seat over the entire circumference when the toilet seat is placed in the closed state.

19 . The toilet device of claim 16 , wherein the drying device blows a gas onto the reverse face of the toilet seat.

20 . The toilet device of claim 16 , wherein the drying device sends warm air to the reverse face of the toilet seat.

21 . The toilet device of claim 16 , further comprising a toilet seat reverse face washing mechanism that supplies a cleaning liquid onto the reverse face of the toilet seat to wash the reverse face, wherein

the drying device performs drying of the reverse face of the toilet seat after the reverse face of the toilet seat is washed.
