[0019]
As shown in FIG. 2, the detergent sprayed by the bathtub detergent nozzle 11 and the fixed nozzles 13 a and 13 b is applied to the corner portion of the bathtub 18 where dirt is easily adhered by the fixed nozzles 13 a and 13 b in which the spraying direction is fixed. The bathtub detergent 18 is sprayed intensively and driven so that the nozzle angle changes in rotation. After spraying the detergent in the bathtub 18, the dirt sprayed from the bathtub water nozzle 2 driven so as to rotate and change the nozzle angle is washed away. The washing on the side of the washing place 19 is the same. After the detergent is sprayed thoroughly from the washing place detergent nozzle 14 to the washing place 19, as shown in FIG. 3, the washing place 19 is driven from the washing place water nozzle 3 which is driven so that the nozzle angle is rotated. Clean with water spray.
[0020]
The rotary spray mechanism that changes the spray direction of water or detergent by driving so that the spray angle changes in rotation is configured as shown in FIG. FIG. 4 shows the drive mechanism of the bathtub water nozzle 2 in cross section. The bathtub water nozzle 2 is attached to a waterproof case disposed in the main body cover 4 of the cleaning device 1 shown in FIG.

As shown in FIGS. 2 and 3, the operation of the cleaning device 1 is controlled automatically by the control unit 16 that is activated by an operation input (operation switch ON) from the operation panel 17, so that the bathtub drains after use of the bathroom. When the operation switch of the operation panel 17 is turned ON after the stopper is pulled out and the remaining hot water in the bathtub 18 is started, the bathtub water nozzle 3 is passed after a predetermined time T01 required for draining from the bathtub 18. Then, water for preliminary cleaning is sprayed from the washing water nozzle 4, and after waiting for a predetermined time T02, the detergent is sprayed from the bathtub detergent nozzle 11, the washing detergent nozzle 14, and the fixed nozzles 13a and 13b. After elapse of time T03 required for the decomposition of the dirt by the detergent, water is sprayed again from the bathtub water nozzle 2 and the washing water nozzle 3, and the dirt decomposed together with the detergent is washed away. After this series of cleaning operations is completed, the bathroom is dried by performing a ventilation operation for a certain period of time.
[0023]
The frequency with which the bathroom cleaning device 1 configured as described above is operated has a long downtime from the cleaning to the next cleaning even when bathing once a day. Ventilation is carried out for a relatively long time to dry the bathroom. In such a use environment of the cleaning apparatus 1, if detergent remains in the vicinity of the detergent ejection holes of the bathtub detergent nozzle 11, the fixed nozzles 13 a and 13 b, and the washing place detergent nozzle 14 provided in the cleaning apparatus 1, the rest time and drying time are increased. There is a risk of drying and solidifying over time and clogging the nozzle holes. In addition, the splashes and sags of the detergent sprayed from the detergent ejection holes adhere to the peripheral part. If the detergent is left unattended, stains may be fixed on the case surface or the like. . As a countermeasure against fouling by this residual detergent, as described above, the auxiliary water spout 6 is provided in each of the bathtub water nozzle 2 and the washing water nozzle 3 to remove the remaining detergent by watering.
[0024]
This sub-sprinkling port 6 is provided in the bathtub water nozzle 2 and the washing area water nozzle 3, and simultaneously sprays the bathtub 18 and the washing area 19, each detergent nozzle 11, 14, each fixed nozzle 13a, 13b and their peripheral parts.
