Abstract

PROBLEM TO BE SOLVED: To provide a simple and inexpensive structure that does not use a motor. SOLUTION: This sanitary washing device 13 comprises a manually operated spiral spring 16, first and second pulleys 25, 26 for transmitting the elastic restoring force of the spiral spring 16, and a tank 17 for storing flush water. The spiral spring 16 is wound, and its elastic restoring force rotates a crown gear 48. The elastic restoring force is transmitted from the second pulley 26 via a transmission belt 63 to rotate the first pulley 25 so as to rotate a blower 21. The flush water in a tank 15 is therefore fed through a feedwater tube 30. Then the pressure applied by a switching valve 33 to the feedwater tube 30 to stop the flush water is removed, causing the flush water to be ejected from the hole 29 of a washing nozzle 15 through the feedwater tube 30. Since the flush water can be fed manually, the need for a water-feeding power source such as a motor or batteries is eliminated.

It is possible to drive the blower 21 for water supply (supplying means) by utilizing the elastic restoring force of the above to supply the wash water.

As shown in FIG. 1, the tank 17 is provided at a position separated from the spiral spring 16 (on the right side in the figure), and is composed of an inner cylinder portion 18 and a side plate 20 functioning as a partition plate. A blower 21 for water supply is housed in the inner cylinder portion 18, and the compartments divided by the side plate 20 are used as the tank 17.

On the other hand, as shown in FIG. 1, a circular hole 31 is formed on one end side (left side in the figure) of the main body 14. Round hole 3
An inner cylindrical wall 32 extending downward is formed on the inner peripheral edge of 1.
An on-off valve 33 is arranged inside the inner cylindrical wall 32.
As will be described later, the operation of the open / close valve 33 controls the water supply of the wash water.

As shown in FIG. 1, the start end portion (left side in the figure) of the spiral spring 16 is attached and fixed to one end peripheral surface portion of the inner cylindrical wall 32. In this example, as shown in FIG. 3, the spiral spring 1
6 is wound in a counterclockwise direction, and a tip end portion (center portion in the figure) of the spiral spring 16 is attached and fixed to a substantially central portion of a rotary shaft 19 for winding (elastically deforming) the spiral spring 16. .

As shown in FIG. 2, the upper end of the rotary shaft 19 is fixedly attached to the rotary disc 54. The rotary disc 54 has a relatively large diameter, and a knob 34 is attached and fixed to the outer end of the rotary disc 54. Therefore, in this example, the spiral spring 16 can be wound while elastically deforming by manually rotating the knob 34 in the direction indicated by the arrow in FIG. 2 (clockwise in the drawing).

Further, as shown in FIG. 1, the rotary shaft 19 is fitted with a small disc 50 in its front half (lower half in the figure) with the rotary shaft hole of the crown gear 48 (crown gear) inserted. It is fixed. The crown gear 48 has a diameter substantially the same as that of the spiral spring 16, and the concave side (inner side) is arranged downward as shown in FIG.

As shown in FIG. 4, a ratchet groove 51 having a plurality of serrated groove portions 52 is formed on the inner peripheral surface of the crown gear 48. The ends of the groove portions 52 are formed clockwise. A pressure spring 49 is attached and fixed to a part of the outer peripheral side of the small disc 50. The pressure spring 49 is bent inward from substantially the center, and a hook portion 49a is formed at the tip thereof. Therefore, FIG.
As shown in FIG. 5, the small disc 50 is assembled inside the crown gear 48 with the hook portion 49 a engaged with the ratchet groove 51 by the elastic force (biasing force) of the pressing spring 49.

When the spiral spring 16 is wound, the small disc 50 rotates together with the rotation of the rotary shaft 19, so that FIG.
As shown in FIG. 4C, the hook 49a of the pressing spring 49 also rotates while engaging with the groove 52 of the ratchet groove 51. That is, the small disk 50 rotates while the hook portion 49a is slightly elastically deformed against the rotation blocking force due to the elastic force of the pressing spring 49. Therefore, when the knob 34 is held and the rotating disk 54 is rotated as shown in FIG. 3, the hook 49a rotates while engaging with the ratchet groove 51 as shown in FIGS. The spiral spring 16 returns to its original position (replaces)
There is no such a case, and the spiral spring 16 can be wound to the end. In this state, as shown in FIG. 1, the crown gear 4
Since 8 is meshed with the stopper piece 46 described later, the crown gear 48 does not rotate and only the spiral spring 16 can be wound.

The cleaning water in the tank 17 is supplied to the cleaning nozzle 15 through the water supply tube 30 by the water supply blower 21.
It is led to. As shown in FIG. 1, one end (left side in the figure) of a rotary shaft 22 that rotationally drives the blower 21 penetrates the end plate 23 of the inner tubular portion 18 and projects to the outside of the tank 17. A substantially central portion of the projected rotary shaft 22 is supported by a support plate 24, and a front half portion of the rotary shaft 22 is inserted and fixed in a rotary shaft hole of a first pulley 25.

In the figure, a seal plate 27 is provided around the rotary shaft 22 so that washing water does not leak through the through hole of the end plate 23.

As shown in FIG. 1, a mounting port 28 functioning as a water inlet is provided in the upper portion of the inner cylindrical portion 18 located in the rotation circumferential surface of the blower 21. In the figure, a mounting port 28 is formed almost directly above the position where the blower 21 is arranged. One end (right side in the figure) of a water supply tube 30 for supplying cleaning water is connected to the attachment port 28, and the other end (left side in the figure) is inserted and attached to the starting end of the cleaning nozzle 15.

As shown in FIG. 1, a shaft 66 is attached and fixed to a support plate 65 provided inside the main body 14. The first half portion (left side in the figure) of the shaft 66 is inserted and fixed in the small gear 58 and the rotary shaft hole of the second pulley 26 integrally fixed to the small gear 58. In the figure, in order to transmit the rotation of the second pulley 26, the first pulley 25 and the second pulley 2
6 is connected via a transmission belt 63.

As shown in FIG. 5A, the on-off valve 33 has a cylindrical portion 36 having a push knob 35 fixedly mounted on the upper end thereof, and the cylindrical portion 36 is inserted into a circular hole 40 of a base 38. A compression spring 45 is interposed at the bottom of the tubular portion 36, and the push knob 35 always projects upward due to its restoring force. A rectangular opening 41 (through hole) is formed in the lower half of the tubular portion 36, and a protrusion 43 is formed on the lower surface of the opening 41.

As shown in FIG. 5A, the base 38 has a U-shape, and its upper plate portion 37 is arranged in the opening 41.
The water supply tube 30 is arranged so as to penetrate the opening 41. The water supply tube 30 has a protrusion 4 as shown in FIG. 5A.
The water supply tube 3
0 is pressed between the upper plate 37 and the protrusion 43 by the elastic force of the compression spring 45, and the flow path is blocked.

For example, as shown in FIG. 5B, when the push knob 35 is pressed against the elastic force of the compression spring 45, the cylindrical portion 36 descends, and the projection 43 also moves in the same direction (in the figure). Since it is displaced to the lower side), the pressing of the water supply tube 30 is released.

Further, as shown in FIG. 1, a stopper piece 46 is attached and fixed to the peripheral surface of the cylindrical portion 36 at one end side (right side in the figure). As shown in the figure, the stopper piece 46 meshes with the crown gear 48 when it is not pushed, so that the rotation of the crown gear 48 is blocked.

A predetermined amount of cleaning water (tap water) is injected into the tank 17 through the water injection port 60. The amount of water injected may be any amount of water according to the amount used. The wash water can be sent smoothly by the one-way valve 62 provided on the side plate 20 of the tank 17 so that the outside air can flow in.

When the sanitary washing device 13 is used, washing water is first put in the tank 17 and the rotary disk 54 is manually rotated by the knob 34 as shown in FIG. 3 to wind the spiral spring 16. The winding work is performed until the spiral spring 16 is completely wound.

In FIG. 6, when the push knob 35 is pushed down, the cylindrical portion 36 descends as described above, and the stopper piece 46 also descends. As a result, the engagement between the stopper piece 46 and the crown gear 48 is released,
The spiral spring 18 rotates in a direction of being restored (rewound) by its elastic restoring force. That is, when the spiral spring 16 is rotated by its elastic restoring force as shown in FIG. 4D, the rotating shaft 19 is also rotated and the small disc 50 is also rotated in the same direction. Therefore, the hook portion 49a of the pressing spring 49 causes the crown gear 48 to rotate (clockwise in the figure) as shown in FIG. 4D.

As shown in FIG. 6, the rotation of the crown gear 48 in this manner causes the small gear (transmission gear) 58 meshing with the crown gear 48 to rotate.
The pulley 26 of also rotates. This allows the second pulley 26
Is transmitted through the transmission belt 63 to rotate the first pulley 25.

As a result, the rotational driving force of the first pulley 25 is transmitted to the blower 21, and the blower 21 rotates, so that the cleaning water in the tank 15 is supplied from the mounting port 28 through the water supply tube 30 to the on-off valve 33. Reach

Here, when the push knob 35 is pushed down, the water stop of the water supply tube 30 which has been pressed by the protrusion 43 at almost the same time as shown in FIG. 5B is released, so that the blower 21 as shown in FIG. 6 is released. The cleaning water sent by the above flows into the cleaning nozzle 15 through the water supply tube 30 and is ejected from the ejection holes 29.

In practice, the user directs the ejection holes 29 of the sanitary washing device 13 to the local area and then pushes the push knob 35 to eject the washing water.

As described above, since the sanitary washing device 13 manually delivers the washing water, a power source such as a motor or a battery is not required. Since the water supply tube 30 is pressed when the device 13 is not used, the wash water stored or remaining in the tank 17 does not leak even when the device 13 is extremely tilted.

Therefore, the present invention is extremely suitable when applied to a portable sanitary washing device or the like, which is required to be small and lightweight for carrying.
