Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a sanitary cleaning device in which the direction of a jet flow discharged from a jet discharge portion is variable.

BACKGROUND ART Conventional cleaning nozzles for sanitary cleaning devices for cleaning private parts of the human body include those with a single-hole discharge port and those with a multi-hole discharge port.

Single-hole cleaning nozzles are suitable for intensive cleaning, and multi-hole cleaning nozzles have a wider cleaning range and are softer to use than single-hole cleaning nozzles.

Problems to be Solved by the Invention The problem to be solved by the present invention is to expand the range that can be cleaned by a cleaning nozzle without reducing the cleaning ability.

To address this problem, conventional single-hole cleaning nozzles have a narrow cleaning range, and to compensate for this, the discharge flow rate has to be increased, resulting in a soft feeling or spatter. There was a problem.

Furthermore, in the case of a multi-hole nozzle, the cleaning range is expanded compared to a single-hole nozzle. However, due to its structure, the required flow rate is large, and the jet stream is dispersed, so that the cleaning effect of the jet stream is reduced.

Means for Solving the Problems In order to achieve the above-mentioned problems, a jet discharge section that sprays cleansing water onto the area to be cleaned of a user seated on a toilet seat, and a hot water tank that supplies hot water to the jet discharge section; A fluid element is provided in the jet discharge section and discharges cleaning water, and further includes means for repeatedly swinging the fluid element in a certain angular range in a direction different from the deflection of the cleaning water discharge direction by the fluid element. .

Function Since the cleaning range is expanded by deflecting a single jet, a powerful cleaning effect is achieved on the contact surface of the jet, and the cleaning range is highly flexible.

Embodiments Embodiments of the present invention will be described below with reference to FIGS. 2 and 3.

In the figure, 1 is a toilet bowl, 2 is a flushing water tank connected to the rear of the toilet bowl, 3 is a flushing toilet seat unit connected to the toilet bowl 1, which includes a hot water unit, a pressurizing part, a cleaning part,
and a built-in control unit to control these, and the toilet seat 4
The toilet lid 5 is pivotably mounted. Reference numeral 6 denotes a water supply pipe that supplies water from the wash water tank 2 to the wash toilet seat unit 3, and is connected to the pump 7. The water pressurized by the pump 7 reaches the lower layer of the hot water tank 9 through a water inlet pipe 10 that communicates with the lower layer of the hot water tank 9 through a discharge flow path 8 . In the hot water tank 9, a sheathed heater 11 is fixed near the bottom of the hot water tank 9, and a temperature sensor 12 provided in the hot water tank 9 detects the water temperature, and the input to the sheathed heater 11 is controlled. . The hot water tap pipe 13 communicates with the upper layer of the hot water tank 9, and is connected to the inlet of the nozzle body 14 via a hot water tap passage 14'. A telescopic nozzle 16 is slidably supported within the nozzle body 14. A single spout 1 is provided at the tip of the telescopic nozzle 16.
7 and a fluidic element 19
The jet stream is set to swing in the direction in which the telescopic nozzle 16 moves in and out. Reference numeral 20 denotes a connecting flow path provided within the expandable nozzle 16, which communicates the inlet portion 15 of the nozzle body 14 with the fluid element 19 of the jet jetting portion 18.

Further, the telescopic nozzle 16 is provided with a groove 21 for preventing rotation, and a gear A23 having a key 22 that matches this groove 21 is slidably provided. The gear A23 is meshed with the gear B24, and rotates while being held between a thrust plate 25 provided integrally with the gear B24 and the tip of the nozzle body 14.

The rotation shaft 28 of the drive motor 27 fixed to the nozzle body 14 is connected to the gear B24 by the fixing member 26, and the rotation of the drive motor 27 is caused by the gear B24,
It is transmitted to the telescopic nozzle 16 via the gear A23, the key 22, and the groove 21. 29 is a spring inserted between the telescopic nozzle 16 and the nozzle body 14 for returning the telescopic nozzle 16. 30 is an O-ring, and when the telescopic nozzle 16 is extended, the telescopic nozzle 1
6 and the nozzle body 14. Reference numeral 31 denotes a control unit, which controls the input of the sheathed heater 11 based on the signal from the temperature sensor 12, controls the start/stop of the hot water temperature control pump 7, controls the pump rotation speed, and controls the amount of rotation of the drive motor. It has a nozzle swing control function that controls the direction.

The drive motor 27 employs a pulse motor and is controlled by a microcomputer in the control section 31, making it possible to memorize the origin during rocking and change the rocking angle.

Next, talking about the operation during cleaning, when the user turns on the cleaning switch (not shown), the pump 7 rotates and pumps hot water from the hot water tank 9 to the hot water outlet channel 1.
4' to the nozzle body 14. The hot water flowing into the nozzle body 14 pushes the telescopic nozzle 16 to the sealing surface where the O-ring 30 is located, and the jet jet part 18 is set in a fixed position.

Furthermore, the hot water reaches the fluid element 19 of the jet jetting part 18 through the connecting channel 20 of the telescopic nozzle 16, and the flow self-oscillated in the fluid element 19 becomes a flow deflected in the direction in which the telescopic nozzle 16 appears and retracts. Further, the telescopic nozzle 16 is connected to the gear A2 by the rotational oscillation of the drive motor 27.
It is transmitted by the third gear B24 and repeats rocking within a certain angle range. Therefore, the jet jet discharged from the jet outlet 17 of the jet discharge section 18 has a combined trajectory of a flow deflected by the fluid element 19 in the direction in which the telescopic nozzle 16 moves in and out, and a flow deflected in a direction perpendicular to this. will move.

The trajectory of the jet flow thus obtained is as shown in FIG. In order to cover a wide cleaning range in a short time, a high deflection speed is required, and deflection using a fluidic element can easily increase the speed.

Furthermore, in this embodiment, since a stepping motor is used to swing the telescopic nozzle 16, it is also possible to change the cleaning density, and a focused cleaning method is adopted using the cleaning pattern shown in Fig. 5. You can also do that.

Effects of the Invention As explained above, the sanitary cleaning device according to the present invention provides the following effects.

(1) Since the cleaning range is expanded by deflecting a single jet, the cleaning ability is stronger and the cleaning range is more flexible compared to multi-hole nozzles.

(2) Since a fluid element is used as the means for deflecting the jet, the deflection can be performed at high speed without impairing the usability.
