[0007]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIGS. 1 and 2 show an embodiment of the present invention. In FIGS. 1 and 2, the same parts as those of FIG. 9 shown in the conventional example are denoted by the same reference numerals. . Reference numeral 11 denotes a cleaning water pressure feed pump provided in the main body case. The pump 11 communicates with the cleaning water injection nozzle 8 via a hot water tank 12. Reference numeral 13 denotes an air compressor provided in the main body case 4. The air compressor 13 communicates with an electromagnetic flow regulating valve 15 via a high-pressure air reservoir 14. Reference numeral 16 denotes a cavity provided in the toilet seat 2. The cavity 16 communicates with the electromagnetic flow regulating valve 15 via a high-pressure hose 17 and has a plurality of air injection nozzles 18. A high pressure air of a constant pressure is stored in the high pressure air reservoir 14 by turning on a main switch (not shown) and operating the air compressor 13.

The operation of the above configuration will be described. First, when cleaning the part to be cleaned of the user 10 after the stool,
When the washing water jetting means is operated, the pump 11 is driven and the hot water in the hot water tank 12 is jetted from the washing water jet nozzle 8 to the portion to be washed of the user 10, so that the water adheres to the portion to be washed of the user 10. The filth is washed away. After the cleaning, when the air high-speed injection means is operated next, the electromagnetic flow regulating valve 1 is operated.

You. The opening of the electromagnetic flow regulating valve 15 is initially reduced to reduce the flow velocity of the air injected from the injection nozzle 18 and gradually widen the opening degree to increase the flow velocity of the air injected from the injection nozzle 18. Thereby, the remaining water droplets adhering to the cleaning part of the user 10 are converged on the part to be cleaned. Thereafter, residual water droplets collected by the high-speed air from the spray nozzle 18 are wiped off. The drying in this case can be performed evenly in a short time by the heating means. In addition,
Since the heating means is energized in one of the energization patterns (A mode, B mode, C mode) shown in FIG. 4, the wind hitting the buttocks does not feel cold at the beginning of drying. Also, the wind does not feel hot immediately before the end of drying. The selection of the A mode, the B mode, and the C mode is performed by a selection switch or the like (not shown).

FIG. 3 schematically shows a method of converging high-speed air injected from the injection nozzle. The method shown in (a) is a method of gradually overlapping and converging the respective injection areas (five points in the drawing) injected from a plurality of (five points in the drawing) injection nozzles, and (b) ) Is a method of individually narrowing the ejection area ejected from each ejection nozzle. In the embodiment shown in FIGS. 1 and 2,

Is a fan motor for blowing hot air, 30 is a heater for generating hot air,
TS is a timer switch having two contacts d and e.

The operation of the above configuration will be described. When the main switch S1 is turned on, the motor 2 of the air compressor 13 is turned on.
5 rotates, and high-pressure air is stored in the high-pressure air reservoir 14. When the high-pressure air reservoir 14 reaches a constant pressure, an unloader (not shown) operates to operate the motor 25 of the air compressor 13.
Stops. When the user cleans the part to be cleaned after the stool, when the operation switch S2 is turned on to the contact b, the motor 26 of the cleaning water pressure pump 11 is rotated to supply hot water from the cleaning water injection nozzle 8 to the user. In order to spray on the part to be cleaned,
The cleaning is performed. In order to remove the residual water droplets adhering to the washing section of the user after this washing, when the operation switch S2 is switched to the contact c, the timer motor 27 is driven and the timer switch TS is connected to the contact d. Therefore, while the electromagnetic flow regulating valve 15 is opened,
The operation of the motor 28 for driving the electric mechanism 23 is started. At this time, since the motor 25 of the air compressor 13 is rotating, high-speed air is
As shown in the drawing, the air is sprayed toward the area to be cleaned of the user 10 and the air injection nozzle 19 is moved in FIGS.
As shown in the drawing, the electric mechanism 23 gradually descends from the dotted line to the solid line state. By such an operation, high-speed air is ejected so as to move and sweep from the vicinity of the portion to be cleaned of the user 10 to the portion to be cleaned as shown in FIG. 5, thereby removing residual water droplets. This air injection is performed for 3 seconds in the present embodiment, and when this time has elapsed, the timer switch 27 is switched from the d contact to the e contact by the operation of the timer motor 27. As a result, the electromagnetic flow regulating valve 15 is closed and the injection of high-speed air is stopped, and the energization of the motor 28 for driving the electric mechanism 23 is stopped.
It returns to the state shown by the dotted line by the return force of 3.

When the timer switch TS is connected from the d contact to the e
By switching to the contact point, the hot air blower fan motor 29 and the hot air generating heater 30 are energized this time, so that the hot air drying is automatically performed following the removal of the remaining water droplets.

In the second embodiment, the position to be jetted to the cleaning section of the user is sequentially moved from the vicinity of the section to be cleaned to the section to be cleaned by vertically moving a pair of air jet nozzles arranged in front and behind. In order to remove the residual water droplets by injecting high-speed air in such a manner, the consumption of high-pressure air is reduced, and as a result, the high-pressure air reservoir 1 of the air compressor 13 is reduced.
4 can be configured with a small capacity.

As described above, according to the present invention, there is provided the high-speed air injection means for injecting air at high speed toward the part to be cleaned of the user after cleaning to scatter or diffuse residual adhered water droplets. For users who have worn underwear just by wiping water drops with paper, after instantaneous injection of high-speed air, it is possible to wear underwear without wiping with paper,
Even for a user who wants to completely dry with warm air, only the residual moisture after the water droplets are removed is dried, so that there is an advantage that the drying time can be greatly reduced.

In any case, since the operation of removing water droplets using paper becomes unnecessary, there is an effect that the characteristics of a clean and sanitary local cleaning device can be fully utilized.
