Good. Furthermore, it is good also as an aspect which provided the mechanism, the operation part, etc. which enable adjustment of the water flow of washing water and temperature adjustment of washing water in the local washing | cleaning apparatus 10.

As shown in FIG. 1A and the like, the local cleaning device 10 is provided with a discharge unit 12 that discharges the coating agent A onto the surface of the nozzle 13. Therefore, when an operation to activate the local cleaning operation, such as an operation (start (ON) operation) of the local cleaning operation unit 11 is detected, the coating agent A is discharged from the discharge unit 12 and the surface of the nozzle 13 is coated with the coating agent. While coating with A, the nozzle 13 is moved in the advance direction.
As described above, the surface of the nozzle 13 is coated with the coating agent A before the local cleaning operation by the nozzle 13 is started, so that dirt such as dirt and splashed water adheres directly to the nozzle 13 during the local cleaning operation. Can be prevented, and the cleanliness of the nozzle 13 can be improved.

  The discharge unit 12 may be provided to discharge the coating agent A from a plurality of directions with respect to the surface of the nozzle 13. In the case of FIG.1 (b), the discharge part 12 is provided not only in the upward direction with respect to the nozzle 13, but also in the left and right sides, and the coating agent A is directed toward the surface of the nozzle 13 from the upward and lateral directions of the nozzle 13. It is configured so that it can be discharged. According to this, the entire surface of the nozzle 13 can be uniformly coated with the coating agent A (see FIGS. 1B and 1C). It should be noted that the position and configuration at which the discharge unit 12 is provided are not limited to the illustrated example. For example, the coating agent A may be sprayed while being dropped (dropped) from the mouth of the discharge unit 12 without being applied and coated.

  Further, as shown in FIG. 2A, it is desirable to start coating so that the coating agent A is discharged from a position avoiding the cleaning water discharge port 13a. In this way, since the nozzle 13 moves in the advance direction while the position of the discharge unit 12 remains fixed, the coating agent A can be applied evenly in the range indicated by the two-dot chain line in FIG. it can. In the local cleaning operation, the area where dirt is particularly attached can be said to be the area indicated by the two-dot chain line in FIG. 2B. If this area is coated with the coating agent A, dirt or the like directly adheres to the nozzle 13. Can be effectively prevented. Further, if the coating agent A is discharged while avoiding the cleaning water discharge port 13a, the coating agent A can be prevented from being mixed into the cleaning water discharged toward the local part of the human body by the nozzle 13.

  As coating agent A, a detergent, a disinfectant, etc. can be used, for example, it is good also as a liquid neutral detergent marketed. As the coating agent A used here, one having a high viscosity is suitably used. When the viscosity of the coating agent A is low, even if the discharge unit 12 discharges the coating agent A while avoiding the cleaning water discharge port 13a of the nozzle 13, the coating agent A is transmitted in the longitudinal direction of the nozzle 13 and is advanced in the advance direction. There is a risk of reaching the cleaning water discharge port 13a. Further, the coating agent A may flow down from the surface of the nozzle 13 into the bowl portion 2 due to gravity during the local cleaning operation, and the coating action of the nozzle 13 may be reduced. Therefore, the discharge part 12 avoids the cleaning water discharge port 13a of the nozzle 13 and discharges the coating agent A having a high viscosity, so that the coating agent A is transmitted in the longitudinal direction of the nozzle 13 to the lower cleaning water discharge port 13a. The risk of reaching is reduced. Further, during the local cleaning operation, the coating agent A is less likely to flow off from the surface of the nozzle 13, and the coating action of the nozzle 13 is easily maintained. Although not shown, the local cleaning device 10 (the toilet device 1) may be provided with a small tank or the like for storing the coating agent A so that the coating agent A can be supplied from the outside of the local cleaning device 10. Good.

  In the local cleaning device 10, a nozzle cleaning unit 16 that cleans the nozzle 13 after the local cleaning operation is completed is provided above the nozzle 13. The nozzle cleaning water discharged from the nozzle cleaning unit 16 and cleaning the nozzle 13 flows down (drops) into the bowl unit 2. In FIG. 1A, the bottom wall provided on the lower side of the nozzle case 14 is inclined so as to incline toward the bowl portion 2, and the lower portion of the nozzle cleaning portion 16 is the bowl portion 2. It is set as the structure opened toward. As shown in FIG. 2B, when the nozzle 13 moves to the storage position, the nozzle cleaning unit 16 discharges the nozzle cleaning water, and the coating agent A coating the nozzle 13 and the coating agent A together with this. The filth that adheres to the surface is washed away. In this way, the nozzle 13 is cleaned and therefore kept clean.

In FIG. 1 and FIG. 2, the nozzle cleaning unit 16 is provided on the front side in the toilet depth direction from the discharge unit 12, but is provided on the rear side in the toilet depth direction from the discharge unit 12 and is configured to be freely advanced and retracted. It is good. The nozzle cleaning unit 16 may be provided in the nozzle case 14.
The nozzle cleaning unit 16 may be provided so as to discharge cleaning water from a plurality of directions with respect to the surface of the nozzle 13. The water temperature and the water flow of the nozzle cleaning water discharged from the nozzle cleaning unit 16 can be appropriately selected by providing a mechanism and an operation unit that can adjust the temperature and the water flow of the nozzle cleaning water in the local cleaning device 10. Also good.
Further, the nozzle cleaning water of the nozzle cleaning unit 16 may be provided by branching from a water supply mechanism that supplies the cleaning water to the bowl unit 2, and the supply source of the nozzle cleaning water may be water. Further, the nozzle cleaning water of the nozzle cleaning unit 16 may be provided by branching from a supply pipe that supplies the local cleaning water to the nozzle 13.

The local cleaning operation unit 11, the local cleaning water supply unit 18, the nozzle cleaning water on / off valve 19, and the nozzle 13 drive unit of the local cleaning device 10 are connected to a control unit that controls these via a signal line or the like. . This control unit executes basic operations described later. Further, the control unit is provided with, for example, a control circuit such as a CPU, a storage unit configured by a memory or the like and storing various operation programs and the like. The control unit may be included in the local cleaning device 10 or the toilet device 1.
Hereinafter, an example of a basic operation executed in the local cleaning device 10 (the toilet device 1) according to the present embodiment will be described with reference to FIG.

  As shown in FIG. 4, in this operation example, when the user performs an ON operation of the local washing operation unit 11 to wash the local part after the stool, the nozzle 13 advances from the storage position toward the washing position. Start. Simultaneously with the start of advancement of the nozzle 13, the coating agent opening / closing valve 17 is opened, and the coating agent A is discharged from the discharge portion 12 toward the surface of the nozzle 13 to start nozzle coating. The movement of the nozzle 13 stops when it reaches the cleaning position, the coating agent on-off valve 17 is closed, and the nozzle coating is stopped. When the nozzle coating is stopped, the local cleaning water supply unit 18 is turned on, and the local cleaning water is discharged from the cleaning water discharge port 13a of the nozzle 13 toward the local part of the human body. In the illustrated example, the local cleaning operation unit 11 is turned on, the nozzle 13 starts to advance, and the coating agent on-off valve 17 is opened at the same time. However, an appropriate delay time or the like may be provided. Similarly, the cleaning position of the nozzle 13 is reached, the coating agent on-off valve 17 is closed, and the local cleaning water supply unit 18 is turned on at the same time, but an appropriate delay time or the like may be provided. Good.

When the local cleaning operation unit 11 is turned off, the local cleaning water supply unit 18 is turned off, and the discharge of the local cleaning water from the cleaning water discharge port 13a is stopped. Thereafter, at the same time that the nozzle 13 starts to retract to the storage position, the nozzle cleaning water on-off valve 19 is opened, the nozzle cleaning unit 16 discharges the nozzle cleaning water, and nozzle cleaning is started. When the nozzle 13 reaches the storage position, the nozzle 13 stops. Simultaneously with the stop of the nozzle 13, the nozzle cleaning water on-off valve 19 is closed, the nozzle cleaning unit 16 stops discharging the nozzle cleaning water, and the nozzle cleaning is completed.
In the example shown in the drawing, the advance speed to the cleaning position of the nozzle 13 at the time of local cleaning and the backward speed to the storage position are substantially the same speed, but different speeds may be used. Further, in the illustrated example, the local cleaning operation unit 11 is turned off, the nozzle 13 starts to be retracted, and the nozzle cleaning water on-off valve 19 is opened at the same time. However, an appropriate delay time or the like may be provided. . The nozzle cleaning may be performed until a predetermined time elapses even when the nozzle 13 reaches the storage position from the viewpoint of maintaining the cleanliness of the nozzle 13.

In addition, from the viewpoint of removing the coating agent A and dirt attached to the nozzle 13 and from the viewpoint of bactericidal properties, the nozzle cleaning water discharged from the nozzle cleaning unit 16 may be heated to an appropriate temperature. It is good also as what heats to about 60 to 100 degreeC. In this case, the nozzle cleaning water may be heated by a common heating device that heats the local cleaning water or the toilet seat 5, or may be heated by providing another heating device. These heating devices are connected to a control unit included in the local cleaning device 10 or the toilet device 1 via a signal or the like and controlled by the control unit.
Moreover, it is good also as a structure which provides a detergent supply apparatus, a sterilization component supply apparatus, etc. in the local washing | cleaning apparatus 10 (toilet device 1), and includes a detergent, a sterilization component, etc. in nozzle washing water.

The operation example shown in FIG. 4 is merely an example, and various modifications can be made.
In the illustrated example, the nozzle 13 is only retracted to the storage position during the nozzle cleaning. For example, when the nozzle 13 is retracted to a predetermined position, the movement may be started again in the advance direction. When the nozzle 13 is moved again in the advance direction, the nozzle cleaning water on-off valve 19 is maintained in an open state, so that the portion once cleaned with the nozzle cleaning water is cleaned again. Then, when the nozzle 13 has advanced to a predetermined position, it starts to move back to the storage position again. Further, the nozzle cleaning may be performed regardless of the presence or absence of local cleaning.

As described above, the local cleaning device 10 according to the present embodiment and the toilet device 1 including the same can improve the cleanliness of the nozzle 13 by adopting the above configuration.
That is, when the operation for operating the local cleaning operation is detected, the discharge unit 12 is configured to coat the surface of the nozzle 13 that supplies the local cleaning water toward the local portion with the coating agent A. Therefore, during the local cleaning operation, the coating agent A prevents dirt and the like from adhering directly to the nozzle 13, and the nozzle 13 is kept clean.
Further, the nozzle 13 is cleaned by the nozzle cleaning unit 16 after the local cleaning operation is completed. Thereby, since the coating agent A, filth, etc. are washed away from the nozzle 13 every time the local cleaning operation is completed, the nozzle 13 is kept clean.
In addition, since the discharge unit 12 is configured to discharge the coating agent A from a plurality of directions on the surface of the nozzle 13, the entire surface of the nozzle 13 is coated with the coating agent A.
Moreover, since the discharge part 12 is set as the structure which discharges the coating agent A avoiding the washing water discharge port 13a which discharges a local wash water toward a local part, it prevents that the coating agent A mixes in a local wash water. be able to.

  In this embodiment, although the example which incorporated the local washing | cleaning apparatus 10 in the toilet device 1 is shown, it is not restricted to such an aspect. For example, the local cleaning device 10 may be installed later in an existing toilet. In this case, the local cleaning device 10 may be a so-called warm water cleaning toilet seat provided with a heating toilet seat and a toilet lid. Further, the shapes and configurations of the toilet device 1, the local cleaning device 10, the discharge unit 12, the nozzle 13, the nozzle case 14, the nozzle cleaning unit 16 and the like in the present embodiment are not limited to the illustrated examples. For example, in FIG. 1A, the nozzle 13 is configured to advance obliquely downward, but the present invention is not limited to this, and the coating agent is configured to advance while maintaining horizontal with respect to the floor surface. A mode in which A does not easily reach the cleaning water discharge port 13a may be adopted. Further, the operations of the local cleaning operation unit 11, the nozzle 13, the coating agent on-off valve 17, the local cleaning water supply unit 18, the nozzle cleaning water on-off valve 19 and the like are not limited to the illustrated examples and the embodiments.
