Description

  The present invention relates to a local cleaning device, and more particularly to a local cleaning device that removes dirt on the outer surface of a local cleaning nozzle by nozzle cleaning.

  Conventionally, as this type of local cleaning device, a local cleaning nozzle for cleaning a local part of a human body is moved back and forth between a rear storage position stored in a nozzle holder and a forward protruding position for performing local cleaning. This is a general structure (see, for example, Patent Document 1).

  In this local cleaning apparatus, when performing local cleaning, the local cleaning nozzle protruding forward approaches the local part of the human body and jets cleaning water from the discharge port. During this cleaning, the local cleaning nozzle tends to be exposed to sewage and filth. Therefore, nozzle cleaning is carried out to wash off dirt adhering to the outer surface of the local cleaning nozzle using cleaning water for local cleaning. In this nozzle cleaning, before or after the local cleaning operation, a predetermined amount of cleaning water is discharged from the discharge port of the local cleaning nozzle in the rear storage position. This cleaning water hits the inner surface of the nozzle holder that covers the local cleaning nozzle, rebounds to the periphery of the discharge port of the local cleaning nozzle, and flushes the dirt adhering to the outer surface of the local cleaning nozzle.

  However, in the conventional example shown in Patent Document 1, the tip 2a of the local cleaning nozzle 2 ″ is formed by a vertical plane orthogonal to the axial direction M of the local cleaning nozzle 2 ″ as shown in FIG. Yes. For this reason, the cleaning water 5 for cleaning the peripheral portion N of the discharge port of the upper surface portion 2d flows down in the direction of the arrow in FIG. As a result, there was a problem that the dirt A adhering to the tip 2a was likely to remain.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a local cleaning device that can easily remove dirt adhered to the tip of the local cleaning nozzle by nozzle cleaning. .

  In order to solve the above-described problems, the present invention provides a discharge port for discharging cleaning water on the upper surface portion of the local cleaning nozzle, and the front and rear positions between the front protruding position where the local cleaning nozzle performs local cleaning and the rear storage position. A local cleaning device that is movably provided and performs nozzle cleaning that removes dirt on the outer surface of the local cleaning nozzle by ejecting cleaning water from a discharge port of the local cleaning nozzle located at the rear storage position. It is characterized in that a water gradient that is inclined so as to be positioned forward from the upper end to the lower end of the nozzle is formed.

  The local cleaning apparatus according to the present invention can easily remove dirt adhered to the tip of the local cleaning nozzle by nozzle cleaning.

It is a perspective view which shows the local cleaning apparatus incorporating the local cleaning nozzle of this embodiment. It is a perspective view which shows the toilet bowl equipped with the local cleaning apparatus same as the above. It is a perspective view which shows the state which made the local washing nozzle same as the above protrude in the front protrusion position. (A) is a perspective view near the front-end | tip part of a local washing nozzle same as the above, (b) is a side view. It is a perspective view near the front-end | tip part of the conventional local washing nozzle.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view showing a local cleaning device 1 incorporating a local cleaning nozzle 2 according to this embodiment, and FIG. 2 is a perspective view showing a toilet 3 equipped with the local cleaning device 1.

  A casing 7 of a sanitary washing device is fixed to the toilet bowl 3, and a toilet seat 8 and a toilet lid 9 are attached to the casing 7 so as to be freely opened and closed. Inside the casing 7 is housed a local cleaning device 1 for local cleaning, a water supply piping system, a hot air drying device for drying after cleaning, and the like (not shown), and each functional unit is an operation unit (not shown). It is driven by.

  The local washing nozzle 2 for washing the buttocks and bidet is connected to an output shaft (not shown) of a motor disposed in the casing 7 (see FIG. 1), and has a rear storage position in FIG. 1 and a forward protruding position in FIG. It moves back and forth with a predetermined stroke in the front-rear direction. 20 in the figure is a nozzle cover that can be freely opened and closed.

  The upper surface 2d of the local cleaning nozzle 2 is provided with a discharge port 4 for discharging the cleaning water 5 upward. At the time of local cleaning, the local cleaning nozzle 2 is projected to the forward protruding position to perform local cleaning. After the local cleaning, the local cleaning nozzle 2 is stored in the rear storage position, and the entire local cleaning nozzle 2 is covered with the nozzle holder 11. The nozzle holder 11 has a cross-sectional shape that covers at least the discharge port 4 of the local cleaning nozzle 2 from above with a predetermined gap, and repels the cleaning water 5 discharged from the discharge port 4 to the outer surface of the local cleaning nozzle 2. The outer surface of the local cleaning nozzle 2 can be cleaned.

  The axial direction M (see FIG. 4B) of the local cleaning nozzle 2 is inclined in a front-lowering manner so that the front end 2a side is lower than the rear end side, and a direction parallel to the axial direction M The local cleaning nozzle 2 moves back and forth toward the front.

  As shown in FIG. 4, the local cleaning nozzle 2 is formed in a top cylindrical shape with the tip 2 a closed. The front end portion 2a of the local cleaning nozzle 2 has a water gradient 6 that is inclined so as to be positioned forward F from the upper end 2b to the lower end 2c. In this example, it inclines down to a flat surface as viewed from the side. As a result, the cleaning water 5 for cleaning the peripheral portion N of the discharge port of the local cleaning nozzle 2 during the nozzle cleaning can easily go around the entire tip portion 2a, and is easy to clean.

  According to the above configuration, nozzle cleaning is performed before or after local cleaning. That is, when the cleaning water 5 is discharged from the discharge port 4 of the local cleaning nozzle 2 in the rear storage position, the cleaning water 5 hits the inner surface of the nozzle holder 11 and the discharge port peripheral portion N ( 4), the dirt adhering to the outer surface of the local cleaning nozzle 2 is washed away. Further, the cleaning water 5 bounced back to the discharge port peripheral portion N flows down along the water gradient 6 indicated by the arrow in FIG. As a result, the dirt A on the tip 2a of the local cleaning nozzle 2 is also washed away.

  As a result, it becomes easy to remove dirt adhering to the tip 2a of the local cleaning nozzle 2 with a simple structure in which the shape of the tip 2a of the local cleaning nozzle 2 is inclined, and the tip 2a of the local cleaning nozzle 2 is cleaned. Improves.

  Moreover, in this example, since the front-end | tip part 2a of the local cleaning nozzle 2 is made to descend | fall and incline on a smooth plane, the washing water 5 becomes easier to flow down and dirt becomes easier to remove.

  If the local cleaning nozzle 2 is not cleaned only by nozzle cleaning, the local cleaning nozzle 2 is pulled forward F and cleaned with a brush or the like. At this time, the tip 2a of the local cleaning nozzle 2 is inclined so as to be positioned forward F from the upper end 2b to the lower end 2c. There is also an advantage that it is easy.
