Abstract

Provided is a sanitary cleansing device configured so that user's defecation can be promoted with a comfortable feeling by spraying of cleansing water. The present invention provides a sanitary cleansing device ( 1 ) including a nozzle assembly ( 6 ) provided with a spray port, a nozzle drive device ( 12 ), an operation device ( 10 ) operated by a user, and a spray control device ( 20 ) configured to actuate the nozzle drive device to execute a massage cleansing mode. The massage cleansing mode is a cleansing mode for repeating a predetermined massage cleansing cycle including a turning movement pattern for turning a water splash point of the cleansing water sprayed from the spray port at the periphery of a private area position of a seated human body and a front-to-back movement pattern for moving the water splash point through the private area position in a substantially front-to-back direction of the human body.

First claim

What is claimed is:

1. A sanitary cleansing device for spraying cleansing water to an ano-genital region of a human body seated on a toilet seat to cleanse the ano-genital region, comprising:
a nozzle assembly provided with a spray port through which the cleansing water is sprayed obliquely upward from a back side to a front side of the seated human body;
a motor configured to drive the nozzle assembly such that a water splash point of the cleansing water sprayed from the spray port moves on the human body in at least two directions including a front-to-back direction and a right-to-left direction;
an operation device operated by a user to start spraying of the cleansing water from the spray port; and
a control unit configured to actuate, based on operation of the operation device, the motor to execute a massage cleansing mode,
wherein the massage cleansing mode is a cleansing mode for repeating a predetermined massage cleansing cycle in which a turning movement pattern and a first movement pattern are alternately repeated,
wherein in the turning movement pattern, the water splash point of the cleansing water sprayed from the spray port is turned around a periphery of an ano-genital region position of the seated human body,
wherein the first movement pattern includes a front-to-back movement pattern or a vibration spot movement pattern wherein each repeated first movement pattern is selected from the group consisting of a front-to-back movement pattern, a vibration spot movement pattern, and combinations thereof,
wherein in the front-to-back movement pattern, the water splash point is moved through the ano-genital region position in the substantially front-to-back direction of the human body, and
wherein in the vibration spot movement pattern, the water splash point is reciprocated in the front-to-back direction of the human body in a stroke shorter than that of the front-to-back movement pattern.

2. The sanitary cleansing device of claim 1 , wherein
the vibration spot movement pattern is a movement pattern for reciprocating the water splash point in the front-to-back direction of the human body in the stroke shorter than that of the front-to-back movement pattern while laterally moving the water splash point in the right-to-left direction.

3. The sanitary cleansing device of claim 1 , wherein
in the massage cleansing cycle, the turning movement pattern, the front-to-back movement pattern, the vibration spot movement pattern, and the turning movement pattern are executed in this order.

4. The sanitary cleansing device of claim 1 , wherein
the turning movement pattern includes a clockwise turning movement pattern and a counterclockwise turning movement pattern.

5. The sanitary cleansing device of claim 4 , wherein
in the massage cleansing cycle, a period for performing the turning movement pattern is longer than a period for performing the front-to-back movement pattern.

6. The sanitary cleansing device of claim 5 , wherein
in one cycle of the single massage cleansing cycle, an amount of the cleansing water sprayed during the turning movement pattern is greater than an amount of the cleansing water sprayed during the first movement pattern.

7. The sanitary cleansing device of claim 5 , further comprising:
a flow velocity changing device configured to change a flow velocity of the cleansing water sprayed from the spray port,
wherein the control unit is programmed to operate the flow velocity changing device such that the flow velocity of the cleansing water sprayed during the first movement pattern is lower than the flow velocity of the cleansing water sprayed during the turning movement pattern.

8. The sanitary cleansing device of claim 5 , wherein
the operation device includes a first operation section configured to execute the massage cleansing mode, and a second operation section configured to execute a fixed spot cleansing mode in which the spray port is stopped at a position at which the cleansing water is splashed on the ano-genital region position of the human body.

9. The sanitary cleansing device of claim 5 , wherein
the first movement pattern is a figure-8-shaped movement pattern in which one-direction front-to-back movement through the ano-genital region position, turning movement halfway around the ano-genital region position, one-direction front-to-back movement through the ano-genital region position, and turning movement halfway around the ano-genital region position in a direction opposite to the previous turning movement are executed in this order.

10. The sanitary cleansing device of claim 5 , wherein
the massage cleansing cycle includes plurality of the front-to-back movement patterns, and each of the front-to-back movement patterns is identical.

11. The sanitary cleansing device of claim 10 , wherein
the first movement pattern is a single cycle of straight reciprocation in which the water splash point is moved from the back side to the front side of the human body, and then the water splash point is moved from the front side to the back side of the human body.
