The second nozzle hose connecting portion 39 is an L-shaped pipe member, and the second nozzle hose 36 is connected as shown in FIG.

In the sanitary cleaning device 3 of the present disclosure, the second nozzle tip 28 is configured as a reforming cartridge 42 incorporating a reforming element 41 that reforms the cleaning water supplied through the second nozzle hose 36. There is.

Here, "reforming" changes the composition and properties of raw water by removing a specific component from raw water (tap water in the case of this embodiment) or adding it to raw water through physical or chemical changes. Say that. The case of undergoing a physical change is, for example, removal of a specific component by adsorption and addition of a specific component by dissolution. The case of undergoing a chemical change is, for example, the removal or addition of a specific component by a chemical reaction or electrolysis. The reforming element 41 in the reforming cartridge 42 of the present embodiment can purify raw water by removing residual chlorine, and purifying the raw water produces purified water as reformed water. In addition to the above, the “modification” may be, for example, the addition of a beauty component, an odor component, a carbonic acid component, a hydrogen component, or the like.

The reforming cartridge 42 has a cylindrical shape as a whole, has a cleaning water ejection hole 43 which is a plurality of small holes in the upper part near the tip, and holds the reforming element 41 inside, and a reforming element cover 44. The element cover 44 has a held portion 45 formed so as to be held on the tip end side of the second nozzle main body portion 26. The modified element 41 is, for example, an activated carbon formed so as to maintain a hollow cylindrical shape that surrounds the outside of a cylindrical vacant space connected to a water pipe in the second nozzle main body 26 with a constant thickness. Can take the form of a filter whose main component is. The modified element 41 can also take the form of a tubular non-woven fabric impregnated with calcium sulfite.

The reforming element cover 44 of the reforming cartridge 42 has a cross-sectional shape similar to that of the columnar second nozzle main body 26, and is a plug-shaped cartridge holding portion 46 provided on the tip side of the second nozzle main body 26. In a state where the socket-shaped held portion 45 is fitted to the second nozzle 22, the second nozzle 22 as a whole exhibits a columnar shape having no step on the outer circumference as shown in the figure.

Next, the operation of the sanitary cleaning device 3 will be described. Here, the operation of the second nozzle 22 will be described. The operation of the first nozzle 21 is substantially the same. During standby before operation, the first nozzle 21 and the second nozzle 22 are in the standby position retracted toward the housing 24 side. In this standby position, the first nozzle tip portion 27 and the second nozzle tip portion 28 on the tip side of each of the first nozzle 21 and the second nozzle 22 are located below the nozzle cleaning portion 23.

When executing the operation of the second nozzle 22, the operation panel 9 is operated so as to execute the operation of the second nozzle 22. In response to this operation, the control unit (not shown) issues a control signal to switch the switching valve 20 so that it is discharged to the nozzle cleaning unit 23, and then starts the pump 40. As a result, the second nozzle tip 28 of the second nozzle 22 is cleaned for a predetermined short time before use by the water discharged from the nozzle cleaning unit 23. In this embodiment, the second nozzle tip 28 is a reforming cartridge 42. As is clear from the system diagram of FIG. 2, cleaning by the nozzle cleaning unit 23 is performed with raw water from which chlorine has not been removed from tap water.

The second motor 32 is activated by the control signal subsequently emitted from the control unit, and the second nozzle 22 extends to the advanced position in accordance with the operation of the rack-pinion mechanism described above. At this advance position, the cleaning water ejection hole 43 on the tip side of the reforming cartridge 42, which is the second nozzle 22, is located at a predetermined position related to cleaning the human body. In other words, when the second nozzle main body 26 of the second nozzle 22 holds the reforming cartridge 42 and is in the above-mentioned advance position, the cleaning water ejection hole 43 of the reforming element cover 44 is used for cleaning the human body. The dimension in the longitudinal direction of the self is specified so as to be located at the predetermined position.

After the reforming cartridge 42, which is the tip end portion 28 of the second nozzle, has moved to its advanced position, the switching valve 20 is switched so as to be discharged to the second nozzle 22 by a control signal subsequently emitted from the control unit. As a result, the cleaning water is ejected from the cleaning water ejection hole 43 of the reforming cartridge 42 to execute the cleaning operation.

During this cleaning operation, the cleaning water supplied from the second nozzle main body 26 of the second nozzle 22 to the reforming cartridge 42, which is the tip 28 of the second nozzle, was arranged in the reforming cartridge 42. It is reformed by the reforming element 41 and injected from the washing water ejection hole 43. Therefore, the entire amount of the washing water reformed by the reforming element 41 can be used for washing the human body. The cleaning of the reforming cartridge 42 itself, which is the tip end portion 28 of the second nozzle, is performed in a state where the switching valve 20 is switched so as to discharge to the nozzle cleaning portion 23 as described above. Therefore, the cleaning water modified by the modification element 41 is not consumed for cleaning the modification cartridge 42 itself.

After the cleaning operation by the second nozzle 22 is completed, the second motor 32 rotates in the reverse direction by the control signal subsequently emitted from the control unit, and the second nozzle 22 moves to the standby position according to the operation of the rack-pinion mechanism described above. Return.

The reforming cartridge 42, which is the tip 28 of the second nozzle of the second nozzle 22, constitutes a plug-socket type connection mechanism that can be attached to and detached from the main body 26 of the second nozzle. Therefore, when the reforming element 41 of the reforming cartridge 42 deteriorates and the reforming ability deteriorates, the reforming cartridge 42 can be removed from the second nozzle main body 26 and replaced. This exchange can be easily performed on the user side at an appropriate time, for example, by a subscription contract between the user and the supplier of the reforming cartridge 42, which is periodically sent from the supplier to the user. It is possible.

In the above description, the second nozzle main body 26 of the second nozzle 22 and the reforming cartridge 42 which is the tip 28 of the second nozzle have been described in detail. Similarly, with respect to the first nozzle main body 25 and the first nozzle tip 27 of the first nozzle 21, the first nozzle tip 27 is used as a reforming cartridge that can be attached to and detached from the first nozzle main body 25. Can be configured.
