DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a local cleaning nozzle device capable of cleaning a local portion while oscillating a cleaning nozzle.

[0002]

2. Description of the Related Art As a local cleaning nozzle device for the above-mentioned purpose, there is one disclosed by the present applicant in Japanese Patent Application Laid-Open No. 64-43633.

In such a local cleaning nozzle apparatus, a nozzle rod is substantially built in a cylinder so as to be movable in the axial direction thereof, a flow path of cleaning water is provided inside the nozzle rod, and a distal end thereof communicates with the flow path. The nozzle rod is provided with an injection hole, and the nozzle rod is reciprocated by an electric motor. The nozzle rod and the output shaft of the electric motor are connected by a power transmission timing belt.

With this configuration, when the cleaning switch is pressed, the electric motor is driven to extend the nozzle rod to a predetermined cleaning position, and at the same time, it is possible to perform anal cleaning or bidet cleaning. In addition, by pressing the swing switch, the nozzle rod can be swung at the anal washing position or the bidet washing position, and the local area can be washed not in the spot but in the area, so that the washing effect can be improved. In addition, an effective massage for treating hemorrhoids and the like can be performed.

[0005]

However, such a local cleaning nozzle device still has the following problems to be solved. That is, the nozzle rod constituting such a local cleaning nozzle device only oscillates at a constant period during the oscillating operation, and thus the local cleaning efficiency and the comfort have not been sufficient. That is, since the ejection area or the cleaning area is constant, the cleaning power becomes uniform as a whole, and a sufficient cleaning effect cannot be obtained. Also, in terms of comfort, the stimulation of the massage is monotonous and no consideration is given to the biological rhythm of the human body, so that some users may feel uncomfortable.

An object of the present invention is to provide a local cleaning nozzle device which can solve the above-mentioned problems.

[0007]

SUMMARY OF THE INVENTION The present invention provides a nozzle rod having a water injection port at a tip thereof, a nozzle motor capable of extending and retracting the nozzle rod into a toilet body, and a power supply for driving the nozzle motor. A control device for outputting a drive signal based on a data series whose spectrum is proportional to the reciprocal of the frequency.

[0008]

According to the present invention, during the swinging operation of the nozzle rod, an irregular signal generator or the like is used to generate a data series whose power spectrum is proportional to the reciprocal of the frequency to the nozzle motor driving circuit of the nozzle motor that drives the nozzle rod. A driving signal is output based on the driving signal. Thereby, the swing amount of the nozzle rod, that is, the cleaning area by the swing can be changed irregularly according to the natural rhythm such as the biological rhythm of the human body, and the massage stimulus can also be changed.
All users can enhance the feeling of use. Further, since the cleaning area changes in a fluctuating manner, the cleaning effect can be improved.

Further, piping for supplying cleaning water to the local cleaning nozzle device A and heating the toilet seat b, all control devices, and the like are also integrally incorporated in the casing c.

The local cleaning nozzle device A has substantially the same configuration as the local cleaning nozzle device described in Japanese Patent Application No. 64-43633 described above, and the configuration thereof is shown in FIGS. The following is a brief description with reference to FIG.

That is, a base 11 fixed to the bottom plate 10 of the casing c is used as a base, a cylinder 12 is integrally provided with the base 11, and a nozzle rod 13 extending toward the ball portion of the toilet bowl B is provided. . Further, a nozzle motor 14 composed of an electric motor for driving the nozzle rod 13 to move forward and backward is disposed at one end of the base 10.

The stroke movement of the nozzle rod 13 is performed by transmitting the rotation of the nozzle motor 14 via a timing belt 15.

A power transmission system using the timing belt 15 includes a driving pulley fixed to an output shaft 14a of the nozzle motor 14.
The main elements are a driven pulley 20b provided as an idler on the side of the cylinder 12 and a timing belt 15 wound around these.

The timing belt 15 is connected and fixed to a side surface of the nozzle rod 13 by a connector 16 as shown in FIG. When the timing belt 15 passes by the driving of the nozzle motor 14 due to the connection and fixing, the nozzle rod 13 moves integrally, and the two cleaning positions are moved.
(Anal washing position and bidet washing position) and a reciprocating movement to a storage position. In addition, as will be described later, the nozzle rod 13 can be swung at each cleaning position by finely reciprocating the timing belt 15 by driving the nozzle motor 14 to rotate forward and reverse.

Further, as shown in FIG.
