[0005] A switching device 30 is connected to the rear portions of the cylinders 12 and 22 via a first feed pipe 16 and a second feed pipe 26. The switching device 30 includes a step motor 32 and a valve mechanism 34, and is configured to distribute hot water from a feed hose 38 to either the first feed pipe 16 or the second feed pipe 26. The upstream end of the feed hose 38 is connected to a hot water tank.

When hot water is supplied from the first feed pipe 16 to the first cylinder 12 by the switching device 30, the first nozzle body 14 moves forward and hot water spouts from the jet port 14a to clean the buttocks (so-called shower washing). Is performed.

When hot water is supplied from the second feed pipe 26 to the second cylinder 22 by the switching device 30, the second nozzle body 24 moves forward, hot water is jetted from the jet port 24a, and bidet washing is performed.

[0008]

If the water pressure supplied to the hot water cleaning nozzle is low, the nozzle bodies 14, 24 advance slowly, and the usability deteriorates. Further, when the water pressure is extremely low, the nozzle bodies 14, 24 may not be sufficiently advanced.

In order to solve such a problem, a pressurizing pump for pressurizing the water supply may be provided, but it is bulky and costly.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a hot water washing nozzle having a nozzle body of a hydraulic advance type capable of reliably advancing the nozzle body with a simple mechanism.

[0011]

According to a first aspect of the present invention, there is provided a hot water washing nozzle comprising: a cylinder; a nozzle body which can be protruded from a tip side of the cylinder by a water pressure of water supplied into the cylinder; A hot-water washing nozzle having a return spring for urging the nozzle body in a retreating direction, characterized in that an auxiliary urging means for assisting the nozzle body to move forward by water pressure is provided.

According to such a hot water washing nozzle, the nozzle body can be sufficiently advanced even when the supply water pressure is low. It is preferable that the auxiliary biasing means includes a wire having a tip connected to the nozzle body and a tension member for pulling the wire. This configuration is very simple, and the nozzle body can be reliably pulled forward.

The auxiliary biasing means may comprise a magnetic body provided on the nozzle body and a solenoid provided on the outer periphery of the cylinder so as to magnetically bias the magnetic body. . By energizing this solenoid, a forward force is applied to the nozzle body. This solenoid need only be wound around the outer periphery of the cylinder, and has a simple structure and good durability.

[0014]

Embodiments of the present invention will be described below with reference to the drawings. 1A and 1B show a hot water washing nozzle according to an embodiment, wherein FIG. 1A is a longitudinal sectional view of the nozzle in the longitudinal direction, and FIG. 2 is an enlarged view of a main part of FIG. 1 (b), FIG. 3 (a) is a perspective view of a toilet seat box provided with the hot water washing nozzle, and FIG. 3 (b) is a view of FIG. 3 (a). It is sectional drawing which follows the BB line.

The hot water washing nozzle has a cylinder 40 made of synthetic resin and a nozzle body 42 which can be protruded from the tip side of the cylinder 40, and the nozzle body 42 is attached to the cylinder 40 in a direction of retracting into the cylinder 40. A return spring 48 is provided. A knob 42b is provided on the tip end surface of the nozzle body 42.

An ejection port 44 is provided on the upper surface on the tip side of the nozzle body 42. A warm water inlet 46 is provided at the rear end of the cylinder 40.

The tip end side of the nozzle body 42 has a non-circular cross-sectional shape. This is because the tip opening 40a of the cylinder 40 has a similar non-circular shape, and the nozzle body 42 rotates around its axis. This is for preventing movement and always pointing the ejection port 44 upward.

When hot water is supplied into the cylinder 40 from the inlet 46 at the rear end of the cylinder 40, the nozzle body 42 moves forward by the water pressure. Then, hot water spouts from the spout 44, and the buttocks of the human body are washed with the hot water. When the supply of hot water is stopped, the nozzle body 42 is retracted by the urging force of the return spring 48. At this time, part of the hot water in the cylinder 40 flows out of the distal end opening 40a of the cylinder 40 through the outer periphery of the nozzle body 42, and the outer surface of the nozzle body 42 is rinsed.

By the way, in order to forcibly advance the nozzle body 42 when the water supply pressure is low, the nozzle body 42
The wire 50 is connected to the rear part of the wire. This wire 50
Is pulled out from the distal end opening 40a of the cylinder 40, passes through the guide tube 52, and is connected to the operation lever 54 (FIG. 3). The distal end of the guide tube 52 is fixed to a convex portion 53 at the distal end of the cylinder 40.

The operation lever 54 is provided with a toilet seat box 56
It is provided in. The toilet seat box 56 is installed on the rear upper surface of a Western-style toilet, and has a hot water washing mechanism such as a hot water washing nozzle installed therein. A toilet seat and a toilet lid (not shown) are attached to the toilet seat box 56 so as to be vertically rotatable.

In this embodiment, a switch panel 58 is provided on the upper surface of the sleeve on the right side of the toilet seat box 56, and an operation lever 54 is provided adjacent to the switch panel 58.
Is provided. The operation lever 54 is pivotally supported at a midpoint in the longitudinal direction by a support shaft 60 to a toilet seat box 56. An upper portion protrudes outside the toilet seat box 56, and a lower portion is disposed in the toilet seat box 56.

A fixed wall 62 is provided on the toilet seat box 56 so as to face a lower portion of the operation lever 54, and a rear end of the guide tube 52 is fixed to the fixed wall 62. The rear end of the wire 50 protrudes from the rear end of the guide tube 52. The rear end of the wire 50 is connected to the lower end of the operation lever 54. Therefore, when the operation lever 54 is rotated as shown by the arrow in FIG. 3, the wire 50 is pulled, and the nozzle body 42 is pulled by the wire 50 and moves forward. For this reason, even in a toilet room where the water supply pressure is low, the nozzle body 42 can be quickly advanced to start hot water washing of the buttocks.

In the embodiment shown in FIGS. 1 to 3, the operation lever 54 is provided on the toilet seat box 56. However, in the case of toilet equipment having a low tank cover, the operation lever 54 may be provided on the low tank cover. Further, a manual operation member such as a knob may be connected to the rear end of the wire instead of the operation lever.

FIG. 4 is a sectional view showing another embodiment of the present invention. In this embodiment, an iron core 70 is provided at the rear of the nozzle body 42, and a plurality of solenoids 72 are provided on the outer periphery of the cylinder 40. These solenoids 7
2 are arranged in the longitudinal direction of the cylinder 40.

When the water supply pressure is low and the advance of the nozzle body 42 is slow or insufficient, the solenoid 72 on the rear side is used.
, A biasing force (magnetic attraction force) is applied to the iron core 70 of the nozzle body 42 in a forward direction to move the nozzle body 42 forward.

The hot water washing nozzle of the present invention can be applied to both a shower nozzle and a bidet nozzle.

[0027]

As described above, according to the hot water washing nozzle of the present invention, the nozzle body can be reliably advanced with a relatively simple configuration. Therefore, the hot water cleaning device can be easily used even in a toilet room with a low water supply pressure.
