【Example】
Embodiments of the present invention will be described below with reference to FIGS.
[0014]
Example 1
FIG. 1 shows a block diagram of a sanitary washing apparatus according to a first embodiment of the present invention. FIG. 2 shows the relationship between the measured value of the nozzle position from the start of cleaning by the air mixing means 6 and the amount of air mixed into the cleaning water 11 by the air mixing means 6 at the start of cleaning in the first embodiment of the present invention. It is. Here, the sanitary washing apparatus of the present invention includes a washing nozzle 29 protruding by the pressure of the fluid, a nozzle position measuring means 4 for measuring the position of the washing nozzle 29, an air mixing means 6 for mixing air into the cleaning water, and an instantaneous The heating means 5 for heating the cleaning water 11 and the control means 30 for controlling the air mixing means 6, and the control means 30 mixes air into the cleaning water 11 based on the nozzle position measurement value from the nozzle position measuring means 4. The air amount control means 31 for controlling the air amount of the air mixing means 6 to be performed, the air mixing operation determination means 32 for determining the timing for operating the air mixing means 6, and the cleaning nozzle 29 based on the nozzle position measurement value from the nozzle position measuring means 4 And a cleaning nozzle protrusion determining means 33 for determining whether the protrusion protrudes to the cleaning position.
[0015]
As shown in FIG. 2, the cleaning nozzle protrusion determining means 33 determines the aeration operation when the measured value of the nozzle position from the nozzle position measuring means 4 is 20 mm when the cleaning nozzle 29 protrudes due to the pressure of the cleaning water 11 from the start of cleaning. Means 32 operates the aeration means 6. At this time, the air amount control means 31 sets the amount of air to be mixed to 600 cc and mixes air so as to push out the washing water 11 already flowing into the washing nozzle 29. Thereafter, the air amount control means 31 sets the air amount mixed by the air mixing means 6 based on the nozzle position measurement value detected by the nozzle position measuring means 4 as shown in FIG. For example, when the nozzle position measurement value of the nozzle position measuring means 4 is 40 mm, the air amount control means 31 sets the air amount mixed by the air mixing means 6 to 350 cc / min and controls the air mixing means 6. Until the nozzle position measurement value of the nozzle position measurement means 4 reaches 100 mm, which is the cleaning position, the air amount control means 31 controls the amount of air mixed in according to the relationship shown in FIG.
[0016]
Thereafter, as shown in FIG. 2, when the aeration means 6 is operated until the measured nozzle position value from the start of cleaning reaches 100 mm which is the cleaning position, the cleaning nozzle protrusion determining means 33 indicates that the cleaning nozzle 29 protrudes to the cleaning position. Therefore, when the nozzle position measurement value reaches 100 mm, the air mixing operation determination unit 32 stops the air mixing unit 6.
[0017]
As described above, in this embodiment, the air mixing operation determination unit 32 controls the operation of the air mixing unit 6 on the basis of the nozzle position measurement value of the nozzle position measuring unit 4 at the start of cleaning. When the cleaning nozzle protrusion determining means 33 determines that the cleaning nozzle 29 does not protrude to the cleaning position based on the nozzle position measurement value of the nozzle position measuring means 4 during operation, the air amount control means 31 mixes the air. By controlling the amount, the cleaning nozzle 29 can be projected to the cleaning position even with a small amount of water, and stable local cleaning can be provided to the user.
[0018]
In this embodiment, the timing of starting air mixing is set when the measured nozzle position value reaches 20 mm, and the timing of stopping air mixing is set when the measured nozzle position value reaches 100 mm. This value can be appropriately selected depending on the washing nozzle to be used.
[0019]
Further, the nozzle position measurement value and the amount of air to be mixed are linearly changed, but the present invention is not limited to this, and it goes without saying that an arbitrary amount of mixing may be set in accordance with the characteristics of the cleaning nozzle.
[0020]
Furthermore, although air mixing is stopped, when a strong cleaning power is required, a necessary amount of air mixing may be performed.
[0021]
(Example 2)
FIG. 3 is a block diagram of a sanitary washing apparatus in the second embodiment of the present invention. The difference from the first embodiment is that the control means 36 is provided with a cleaning time measuring means 34 for measuring the cleaning time from the start of cleaning. Other components are the same as those in the first embodiment, and a description thereof will be omitted. The cleaning time measuring means 34 measures the cleaning time from the start of cleaning. FIG. 4 shows the relationship between the cleaning elapsed time from the start of operation of the air mixing means 6 and the amount of air mixed in the cleaning water 11 by the air mixing means 6 at the start of cleaning in the second embodiment of the present invention. Next, the operation of the cleaning time measuring unit 34 will be described. As shown in FIG. 4, the cleaning time measuring unit 34 measures the cleaning time from the start of cleaning, and when the elapsed cleaning time has passed 2 seconds, the air mixing operation determination unit 32 operates the air mixing unit 6. At that time, the air amount control means 31 sets the amount of air to be mixed to 600 cc and mixes air so as to push out the washing water 11 flowing into the washing nozzle 29 for 2 seconds from the start of washing. Thereafter, according to the elapsed time of the cleaning time measuring means 34, the air amount control means 31 reduces the amount of air mixed in from 600 cc / min. When the cleaning nozzle protrusion determining means 33 determines that the cleaning nozzle 29 protrudes to the cleaning position, the air mixing means 6 is stopped. For example, as shown in FIG. 4, when the cleaning elapsed time of the cleaning time measuring means 34 is 6 seconds, the air mixing means 6 is stopped when the cleaning nozzle protrusion determining means 33 determines that the cleaning nozzle 29 protrudes to the cleaning position.
[0022]
As described above, in this embodiment, based on the cleaning elapsed time of the cleaning time measuring unit 34 at the start of cleaning, the air mixing operation determination unit 32 mixes the operation of the air mixing unit 6 and the air amount control unit 31 mixes. By controlling the amount of air, even if the amount of water is small, the cleaning nozzle 29 protrudes to the cleaning position, so that stable local cleaning can be provided to the user.
[0023]
(Example 3)
FIG. 5 is a block diagram of a sanitary washing device according to a third embodiment of the present invention. The difference from the second embodiment is that the control means 37 is provided with a cleaning stop time measuring means 35 for measuring the elapsed time since the cleaning stop, and the nozzle position measuring means 4, the cleaning nozzle protrusion determining means 33 and the cleaning time measuring means 34 are provided. There is no point. Other components are the same as those in the second embodiment, and a description thereof will be omitted. The cleaning stop time measuring means 35 measures the time during the cleaning stop, and measures the elapsed time after the cleaning stop state. FIG. 6 shows the relationship between the stop elapsed time from the start of operation of the air mixing means 6 and the amount of air mixed in the remaining cleaning water 11 when the air mixing means 6 remains when cleaning is stopped in the third embodiment of the present invention. It is shown. As shown in FIG. 6, when the cleaning operation is stopped, the air mixing operation determination unit 32 determines that it is necessary to mix air in order to discharge the remaining cleaning water from the cleaning nozzle 29, and operates the air mixing unit 6. For the first 2 seconds, the air amount control means 31 gradually increases the amount of air to be mixed, and thereafter, from 2 seconds to 6 seconds, 300 cc / min of air is mixed. As a result, the cleaning water 11 remaining in the cleaning nozzle 29 is pushed out from the cleaning nozzle 29 and discharged. When the elapsed time of the cleaning stop time measuring means 35 has elapsed 6 seconds, the air mixing operation determining means 32 determines that all the cleaning water 11 remaining in the cleaning nozzle 29 has been discharged and stops the air mixing means 6. In this way, by mixing air so that the cleaning water 11 is pushed out from the air mixing means 6 when cleaning is stopped, all the cleaning water remaining in the cleaning nozzle 29 is discharged, and the user uses the next sanitary cleaning device. In this case, the cleaning water remaining in the cleaning nozzle 29 is not ejected to the local area, and a comfortable local cleaning can be performed.
[0024]
As described above, in this embodiment, all the cleaning water is discharged by mixing air so that the cleaning water remaining in the cleaning nozzle 29 is pushed out from the air mixing means 6 when cleaning is stopped. Comfortable local cleaning can be provided when the sanitary cleaning device is used next time.
