It is configured to land on water with a low landing force. Further, since the narrow mode water jetting and the wide mode water jetting are performed by one water jetting hole, the water landing force is controlled for the entire narrow mode water jetting and the wide mode water jetting as a whole.

Japanese Patent No. 5633867

The area spouted in the narrow mode corresponds to the periphery of the local area where more dirt adheres. If the water landing force in the range where water is spouted in the narrow mode is small, there is a concern that the dirt on the part where the most dirt adheres cannot be sufficiently removed. In addition, it has been desired to effectively clean a portion to which a large amount of dirt adheres, even when water is being discharged in the wide mode.

The present invention includes a long nozzle portion (for example, a nozzle portion 12 to be described later) which is provided so as to be able to advance and retreat in the front-rear direction with respect to the rear portion of a toilet bowl (for example, a toilet bowl 71 to be described later), and whose longitudinal direction is the front-rear direction; a bidet washing device (for example, In a bidet cleaning apparatus 1) described later, the plurality of water discharge hole groups are narrow-area water discharge holes for narrow-mode water discharge (for example, narrow-area water discharge holes described later) that discharge water to a predetermined range near the body part. group 21, narrow-area water discharge hole 21C), and a wide-area water discharge hole group for wide-mode water discharge (for example, a wide-area water discharge hole group 22 described later) for discharging water in a range wider than the predetermined range, Of the wide mode water landing range (for example, a wide mode water landing range W1 to be described later) in which the wash water discharged from the water discharge hole group lands on the user, the wash water discharged from the narrow water discharge holes The water landing force at a core water landing portion (for example, a core water landing portion 221 to be described later) that overlaps the narrow mode water landing range (for example, a narrow mode water landing range N1 to be described later) that lands on the user is the wide mode water landing force. It relates to a bidet cleaning device that is higher than a peripheral water landing portion (for example, a peripheral water landing portion 222 to be described later) that does not overlap the narrow mode water landing range.

It is preferable that the water landing force in the narrow mode water landing area is higher than the water landing force of the peripheral water landing portion in the wide mode water landing area.

It is preferable that the water landing force in the narrow mode water landing area is substantially the same as the water landing force of the core water landing portion in the wide mode water landing area.

The wide mode water jetting has a simultaneous water jetting mode in which water is jetted simultaneously from both the wide water jetting hole group and the narrow water jetting hole group. It is preferable that the water force is smaller than the landing force of cleansing water discharged from the narrow-area water discharge holes, and the wide-area water discharge hole group discharges water so as to surround the narrow-area water discharge holes.

It is preferable that the water landing force is changed by changing the diameter of each of the water discharge holes (for example, the water discharge holes 20 described later) that constitute the plurality of water discharge hole groups.

According to the present invention, it is possible to provide a bidet cleaning device that can effectively clean a portion to which a large amount of dirt adheres even when water is being discharged in the wide mode.

Wide-area water discharge hole group 22, and wash water discharged from narrow-area water discharge hole 21 is used in wide-mode water landing range where wash water discharged from wide-area water discharge hole group 22 lands on the user. The landing force in the core water landing portion 221 overlapping the narrow mode water landing range for landing on a person is made higher than the peripheral water landing portion 222 not overlapping the narrow mode water landing range in the wide mode water landing range.
Since the wide-area water discharge hole group 22 has a plurality of water discharge holes 20 , the water landing force can be distributed within the wide-area water discharge hole group 22 so as to have a difference in level. Specifically, the water landing force of the core water landing portion 221 that overlaps with the narrow mode water landing range N1 of the wide mode water landing range W1 is set to It can be made higher than the water landing force of the peripheral water landing portion 222 . As a result, it is possible to efficiently and effectively wash the portion to which dirt is most likely to adhere during the wide mode water jetting.

In this embodiment, the water landing force in the narrow mode water landing range N1 is made higher than the water landing force of the peripheral water landing portion 222 in the wide mode water landing range W1. As a result, regardless of whether the narrow mode water spouting is performed alone or the wide mode water spouting alone, the part to which dirt is most likely to adhere can be washed efficiently and effectively.
