Abstract

A sanitary washing device includes: a sprayer that jets a liquid to a surface of a toilet bowl portion of a toilet bowl; and a movable-type scattering suppression member that is movable between a closed position and an opened position and suppresses the liquid jetted from the sprayer from scattering to an upper surface side of the toilet bowl at the opened position.

First claim

What is claimed is:

1. A sanitary washing device comprising:
a sprayer that jets a liquid to a surface of a toilet bowl portion of a toilet bowl;
a human-body washing nozzle that includes a cylinder portion;
a movable-type scattering suppression member that is movable between a closed position and an opened position and suppresses the liquid jetted from the sprayer from scattering to an upper surface side of the toilet bowl at the opened position;
a casing configured to hold the sprayer, accommodate the human-body washing nozzle, and rotatably support the scattering suppression member;
a connection member that includes one end portion rotatably supported by the casing, the other end portion fixed to the scattering suppression member; and
a rotating member that is rotatably supported by the casing, pressed and rotated by the cylinder portion,
wherein the rotating member is pressed by the cylinder portion during at least a part of the linear motion of the cylinder portion,
the connection member is pressed by the cylinder portion during at least a part of the linear motion of the cylinder portion;
pressing of the connection member by the cylinder portion is initiated before pressing of the rotating member by the cylinder portion is terminated, and
the pressing of the connection member by the cylinder portion is continued after the pressing of the rotating member by the cylinder portion is terminated.

2. The sanitary washing device according to claim 1 ,
wherein the human-body washing nozzle is movable back and forth and jets a liquid to a local region of a human body,
wherein the scattering suppression member moves between the closed position and the opened position in conjunction with forward and backward movements of the human-body washing nozzle.

3. The sanitary washing device according to claim 2 ,
wherein the scattering suppression member covers a tip end portion of the human-body washing nozzle at the closed position.

4. The sanitary washing device according to claim 3 , further comprising:
a motion conversion mechanism that converts a linear motion of the human-body washing nozzle into a rotational motion of the scattering suppression member.

5. The sanitary washing device according to claim 4 ,
wherein the human-body washing nozzle includes a nozzle body having a liquid jetting port and the cylinder portion that accommodates the nozzle body therein,
the nozzle body is movable back and forth relative to the cylinder portion,
the cylinder portion is movable back and forth relative to the casing, and
the motion conversion mechanism converts a linear motion of the cylinder portion into a rotational motion of the scattering suppression member.

6. The sanitary washing device according to claim 5 ,
wherein the motion conversion mechanism is a link mechanism having one end connected to the scattering suppression member, and
the link mechanism includes a slider provided on the other end side thereof, the slider being guided by the casing and pressed by the cylinder portion.

7. The sanitary washing device according to claim 5 ,
wherein the motion conversion mechanism includes:
the connection member, a curved portion formed between the one end portion and the other end portion, and a pressed portion provided on the curved portion; and
the rotating member that presses the pressed portion of the connection member so as to allow the connection member to rotate relative to the casing.

8. The sanitary washing device according to claim 2 , further comprising:
a motion conversion mechanism that converts a linear motion of the human-body washing nozzle into a rotational motion of the scattering suppression member.

9. The sanitary washing device according to claim 8 ,
wherein the human-body washing nozzle includes a nozzle body having a liquid jetting port and the cylinder portion that accommodates the nozzle body therein,
the nozzle body is movable back and forth relative to the cylinder portion,
the cylinder portion is movable back and forth relative to the casing, and
the motion conversion mechanism converts a linear motion of the cylinder portion into a rotational motion of the scattering suppression member.

10. The sanitary washing device according to claim 9 ,
wherein the motion conversion mechanism is a link mechanism having one end connected to the scattering suppression member, and
the link mechanism includes a slider provided on the other end side thereof, the slider being guided by the casing and pressed by the cylinder portion.

11. The sanitary washing device according to claim 9 ,
wherein the motion conversion mechanism includes:
the connection member, a curved portion formed between the one end portion and the other end portion, and a pressed portion provided on the curved portion; and
the rotating member that presses the pressed portion of the connection member so as to allow the connection member to rotate relative to the casing.
