The cleaning water is spouted over a wide range.

Next, the sanitary washing device 10 and the nozzle device 1
The cleaning operation of No. 2 will be described. Now, the user has a toilet seat 1
When seated at 7, the drive motor 82 is driven to advance to a position where the second ejection port 72b of the nozzle head 70 is connected to the pre-cleaning passage 120 of the nozzle cleaning cover 100 and stop (position in FIG. 9). After that, the second opening / closing valve 37b is opened, and the cleaning water is ejected from the second ejection port 72b through the supply pipe 92b and the second passage 62b. The cleaning water ejected from the second ejection port 72b is ejected from the pre-cleaning passage 120 through the pre-cleaning ejection port 120a toward the ball surface 5a of the toilet body 5 for a predetermined time. After that, the second opening / closing valve 37b is closed, and the ejection of washing water is stopped. After that, the drive pulley 84 is rotated by the drive motor 82 and the timing belt 88 is caused to travel, whereby the nozzle body 6
0 is slightly retracted, and the nozzle head 70 stops at the nozzle cleaning position housed in the cleaning chamber 107 (position in FIG. 8).

After the urination, the user operates the operation panel 1
When the anal cleansing button 13a of No. 3 is pressed, the hot water / nozzle control device 14 opens the first opening / closing valve 37a and the second opening / closing valve 37b, and the heat exchanger 30 connects to the supply pipes 92a and 92b to connect the first passage 62a. , Supply the cleaning water to the second passage 62b.
Water that has passed through the first passage 62a and the second passage 62b is ejected from the first ejection port 72a and the second ejection port 72b. The sprayed cleaning water is used for the nozzle cleaning surface 1 of the nozzle cleaning cover 100.
16 and bounces off, and becomes a flow along it, and flows down from the lower end opening portion 114 of the nozzle cleaning cover 100 to the ball surface 5a of the toilet body 5, and by this flow dirt and the like adhering to the peripheral surface of the nozzle head 70 is predetermined. Wash off for hours.

After cleaning the nozzle head 70, the drive motor 82 advances the nozzle body 60 to a predetermined stroke. At the same time, the heat exchanger 30
The cleaning water from is switched to only the supply pipe 92a side. When the cleaning water is supplied from the supply pipe 92a, the first passage 6
2a flows into the nozzle head 70, and washing water is jetted from the first jet port 72a for anus washing. This allows
Anus cleansing is performed. Then, when the stop button 13c is pressed, the supply of washing water is stopped, and the drive motor 82 is further rotated in the reverse direction to return the nozzle body 60 to the housed state shown in FIG.

Instead of the anus wash button 13a,
When the bidet cleaning button 13b is turned on, the nozzle main body 60 advances to the anus cleaning position after performing the same operation up to the nozzle cleaning operation, and the cleaning water is supplied from the supply pipe 92b to the second ejection port 72b. Erupted. Then, the drive motor 82 is rotated in the reverse direction to return the nozzle body 60 to the housed state.

Therefore, according to the nozzle device 12, the second jet outlet 72a of the nozzle head 70 is connected to the pre-cleaning passage 120 of the nozzle cleaning cover 100 when seated on the toilet seat 17, and the pre-cleaning spray is carried out. Since the wash water is jetted from the outlet 120a toward the ball surface 5a of the toilet body 5, it is possible to prevent the attachment of stool. Further, in order to perform the pre-cleaning, the nozzle cleaning cover 100 for cleaning the nozzle is integrally provided with the pre-cleaning passage 120 and the second passage 62b for cleaning the bidet is used. As described above, it is not necessary to provide a nozzle for pre-cleaning or a pipe path different from the nozzle device 12, and the configuration is simple.

Although the pre-cleaning passage 120 is formed in the nozzle cleaning cover 100 at the tip of the casing main body 11, the present invention is not limited to this. It may be provided at a position suitable for pre-cleaning, and its position is not particularly limited.
For example, the pre-cleaning passage may be formed as a dedicated member supported by the supporting member by projecting a supporting member from the casing body of the sanitary cleaning device.

FIG. 10 shows an embodiment in which the passage forming member 130 is of a movable type so that the nozzle body 60 can be moved forward and backward so that pre-cleaning can be performed at any position. As shown in FIG. 10, the passage forming member 130 includes a pre-cleaning passage 131.

By controlling the drive amount of the nozzles and moving the passage forming member 130 in accordance with the position of the nozzle head 70, pre-cleaning can be performed by ejecting cleaning water from the pre-cleaning passage 131 at an arbitrary position.

11 and 12 show the periphery of a nozzle head 210 and a nozzle cleaning cover 230 according to another embodiment. At the tip of the nozzle body 200, the nozzle head 210
Are connected. A first passage 212a and a second passage 212b are formed in the nozzle head 210, and these passages are connected to the first passage 202a and the second passage 202b in the nozzle body 200, respectively. The first passage 212a has an opening at the first ejection port 213a, and the second passage 212b has an opening at the second ejection port 213b. A pre-cleaning passage 214 is formed in the nozzle head 210. Pre-cleaning passage 214
Has a pre-cleaning supply port 214a on the lower end side of the nozzle head 210 and a pre-cleaning ejection port 214b on the tip end side of the nozzle head 210. The pre-cleaning spout 214b is formed obliquely downward so that the cleaning water is spouted onto the ball surface 5a (see FIG. 1) of the toilet body 5.

The case opening 1 of the casing body 11
A connection fitting 220 is fixed to 1a. The connection fitting 220 includes a nozzle body 200 and a nozzle head 210.
Is formed with a sliding surface 221. The sliding surface 221 is formed with a connection port 222 connected to the supply pipeline 223. The supply pipeline 223 is connected to the opening / closing valve 37c of the opening / closing valve unit 37 (see FIG. 2) and supplies the cleaning water.

The case opening 1 of the casing body 11
A nozzle cleaning cover 230 is provided on 1a.
The nozzle cleaning cover 230 has a cleaning surface 232 at portions facing the first ejection port 213a and the second ejection port 213b of the nozzle head 210, respectively.

At the nozzle cleaning position shown in FIG. 11, from the first passage 202a and the second passage 202b to the first passage 212a.
The cleaning water that has flowed through the second passage 212b and the second passage 212b is
13a and the second ejection port 213b, and is reflected by the cleaning surface 232 of the nozzle cleaning cover 230 to reflect the first ejection port 2
13a and the periphery of the second ejection port 213b are cleaned.

On the other hand, when the pre-cleaning command is issued, the drive motor (see FIG. 4) is driven and the nozzle body 200 and the nozzle head advance to the position shown in FIG. At this time, the connection port 222 of the pre-cleaning passage 214 is connected to the supply pipeline 223.
Connected to. Then, the opening / closing valve 37c is opened, and the cleaning water is supplied to the pre-cleaning passage 214 via the supply pipeline 223. As a result, the cleaning water is ejected from the pre-cleaning passage 214 through the pre-cleaning ejection port 214b. Since the pre-cleaning ejection port 214b is provided so as to be ejected toward the ball surface 5a of the toilet body 5, the cleaning water wets the ball surface 5a and prevents the stool from adhering to the ball surface 5a. To be done.

[0036]

As described above, according to the inventions of claims 1 and 2, by supplying the cleaning water ejected from the ejection port of the cleaning nozzle to the pre-cleaning passage of the passage forming member, Pre-cleaning can be performed by utilizing the water channel system of the cleaning nozzle. Therefore, to perform pre-cleaning,
There is no need to provide a nozzle different from the cleaning nozzle and a dedicated solenoid valve, and the configuration is simple. Further, since the pre-cleaning nozzle does not come out from the bottom surface of the main body, there is no fear of breakage, and the occurrence of dirt due to scattering of dirt is small.

Further, according to claims 3 and 4,
Since a passage for washing a person's local area and a pre-washing passage are provided integrally with the nozzle main body, and a separate pre-washing nozzle is not provided, the configuration is simple.
