According to the sanitary washing device 2 according to the present embodiment described above, the size of the device can be reduced, and good workability can be achieved in holding the water supply tubes 51 and 52 and the wire harness 53 around the nozzle 31. Obtainable.

That is, the sanitary washing device 2 according to the present embodiment includes a tube holding portion 102 holding the nozzle washing tube 52 and an electric wire holding portion holding the wire harness 53 in the nozzle support 34 constituting the nozzle unit 15. 103 is provided. According to such a configuration, it is possible to completely hold the nozzle cleaning tube 52 and the wire harness 53 within the nozzle unit 15 . As a result, it is possible to perform the work of holding the members 52 and 53 to be held in the nozzle unit 15 before it is attached to the base plate 5a, so that the assembling workability can be improved.

For example, a configuration is assumed in which a portion for holding the nozzle cleaning tube 52 or the wire harness 53 is provided in the tank 26 located on the left side of the nozzle 31 . In such a configuration, the operation of holding the water supply tube or electric wire to the holding portion provided on the tank 26 is performed with the nozzle unit 15 attached to the base plate 5a. For this reason, there is a problem that a sufficient work space cannot be obtained for holding the water supply tube or the electric wire, and surrounding devices and equipment become obstacles, resulting in deterioration of workability. Such a problem becomes conspicuous as the device becomes more compact.

In this respect, according to the sanitary washing device 2 according to the present embodiment, it is possible to perform the work of holding the held members 52 and 53 with the nozzle unit 15 alone as described above. It is possible to improve the workability of the holding work. As a result, there is no need to consider the work space for holding the members 52 and 53 to be held on the base plate 5a, so space can be saved and the device can be made compact. As described above, according to the sanitary washing device 2 according to the present embodiment, it is possible to achieve both compactness of the device and improvement in holding workability of the held members 52 and 53 .

Further, in the sanitary washing device 2 according to the present embodiment, both the tube holding portion 102 and the wire holding portion 103 are arranged on the left side of the nozzle 31 .

According to such a configuration, the nozzle cleaning tube 52 and the wire harness 53 can be arranged so that parts of the movement space (movable space) of the respective nozzle interlocking portions overlap each other. Thereby, the space in the casing 5 can be shared as a moving space for the nozzle interlocking portions of the nozzle cleaning tube 52 and the wire harness 53 . Therefore, compared to a configuration in which, for example, the nozzle cleaning tube 52 and the wire harness 53 are held on both the left and right sides of the nozzle 31, the space around the nozzle 31 in the casing 5, particularly the space between the nozzle 31 and the tank 26 (the left side of the nozzle) The space 105) can be effectively used, and the size of the casing 5 can be reduced.

In addition, in the sanitary washing device 2 according to the present embodiment, the tube holding portion 102 and the wire holding portion 103 are provided so that the wire harness 53 is not deformed by the water supply tubes 51 and 52 in the process of advancing and retracting the nozzle. there is

That is, in the configuration in which the moving space of the nozzle interlocking portions of the nozzle cleaning tube 52 and the wire harness 53 are shared as described above, depending on the manner in which these held members 52 and 53 are arranged, the nozzle advance/retreat operation may be affected. As a result, it is conceivable that the water supply tube and the electric wire interfere with each other. If the water supply tube and the electric wire interfere with each other, the electric wire, which is weaker than the water supply tube, will be forcibly deformed by the pressure from the water supply tube, resulting in repeated bending deformation and wear due to sliding resistance during long-term use. A problem may arise in that the deterioration of the electric wire is likely to progress due to this. Therefore, according to the arrangement mode of the water supply tube and the electric wire as described above, it is possible to avoid the mutual interference caused by the advance and retreat operation of the nozzle, and it is possible to suppress the deterioration of the wire harness 53 .

Specifically, the sanitary washing device 2 of this embodiment has a configuration in which the nozzle interlocking portion of the wire harness 53 is arranged outside the nozzle interlocking portions of the water supply tubes 51 and 52 .

With such a configuration, it is possible to prevent the water supply tubes 51 and 52 from interfering with the wire harness 53 so as to cause deformation during the nozzle forward/backward movement. deterioration can be suppressed.

Further, in the sanitary washing device 2 of the present embodiment, the electric wire holding portion 103 is arranged on the left side of the tube holding portion 102 , which is the side opposite to the nozzle, and the wire harness 53 is arranged on the left side of the nozzle washing tube 52 . It is arranged in the front-rear direction substantially parallel to the nozzle cleaning tube 52 at the position of .

According to such a configuration, the nozzle cleaning tube 52 and the wire harness 53 intersect, for example, and the nozzle cleaning tube 52 interferes with the wire harness 53 so as to cause deformation during the nozzle advancing/retreating operation. can be prevented. As a result, bending deformation of the wire harness 53 due to interference or contact with the wire harness 53 from the nozzle cleaning tube 52 and wear due to sliding resistance can be reduced, and deterioration of the wire harness 53 due to the forward and backward movement of the nozzle can be suppressed. can be done. Further, since the nozzle cleaning tube 52 and the wire harness 53 can be held in parallel, the space on the left side of the nozzle 31 (nozzle left side space 105) serving as a space for arranging the water supply tube and the electric wire can be effectively utilized. , can contribute to the compactness of the device.

Here, an example of the operation mode of the water supply tubes 51 and 52 and the wire harness 53 accompanying the advancing/retreating operation of the nozzle in the sanitary washing device 2 according to this embodiment will be described with reference to FIG. 21 . FIG. 21 is a diagram schematically showing an example of an operation mode of the water supply tube and the electric wire accompanying the advance/retreat operation of the nozzle. In addition, in FIG. 21, only the second wiring portion 53b and the third wiring portion 53c, which are the nozzle interlocking portions, of the wire harness 53 are shown.

FIG. 21A shows a state in which the nozzle 31 is housed in the casing 5, that is, a state in which the nozzle 31 is at the retracted end (hereinafter referred to as "nozzle housed state"). FIG. 21B shows a state in which the nozzle 31 is at an intermediate position in the movement range of its forward/backward movement (hereinafter referred to as "nozzle intermediate state"). FIG. 21C shows a state in which the nozzle 31 protrudes forward, that is, a state in which the nozzle 31 is at the forward end (hereinafter referred to as "nozzle protruding state").

That is, in the forward motion of the nozzle 31 (hereinafter referred to as “nozzle forward motion”), the water supply tube and the electric wire move from the nozzle retracted state shown in FIG. 21A to the nozzle intermediate state shown in FIG. state. 21C, the nozzle intermediate state shown in FIG. state.

As shown in FIGS. 21A, 21B and 21C, during the nozzle advancing operation, the connection block portion 58 to which the downstream end of the unit water supply tube 51 and the upstream end of the nozzle cleaning tube 52 are connected serves as a nozzle support. It moves from a position near the rear end of the face portion 71 to a position near the nozzle cleaning chamber 32 . Therefore, in the forward movement of the nozzle, the unit water supply tube 51 is folded rearward from the upstream curved portion 51a to the intermediate extended portion 51b (see FIG. 21A), and moves downstream from the connecting portion to the delivery pipe portion 57 as a starting point. The side end portion is moved forward to reach a state of being extended forward (see FIG. 21C). Further, in the nozzle advancing operation, the nozzle cleaning tube 52 maintains the rearward folded form from the upstream curved portion 52a to the intermediate extended portion 52b, and shifts the folded position, and finally, substantially the entirety of the nozzle cleaning tube 52 is extended by two. It is in a folded state (see FIG. 21C).

Further, in the nozzle advancing operation, the first harness holding portion 110 where the portion of the wire harness 53 on the base end side of the nozzle interlocking portion is located moves from the position near the rear end portion of the nozzle support surface portion 71 to the vicinity of the nozzle cleaning chamber 32 . position. Therefore, in the nozzle advancing operation, the nozzle interlocking portion of the wire harness 53 moves forward from the portion held by the wire holding portion 103 as a starting point while maintaining the rearward folded form.

In this manner of movement of the water supply tube and wiring accompanying the forward movement of the nozzle, the wire harness 53 located on the rear side and the left side (opposite side of the nozzle) of the water supply tubes 51 and 52 in the nozzle stored state is connected to the water supply tube 51, 52. While maintaining a relative positional relationship with respect to 52, it moves in a manner to follow the water supply tubes 51 and 52 that escape forward as the nozzle advances.

In addition, the movement of the water supply tube and wiring during the nozzle retraction operation is such that the water supply tube and wiring moved by the nozzle forward movement return from the wiring manner in which the nozzle is protruded to the original state, that is, the wiring manner in which the nozzle is housed. move to

Thus, according to the wiring mode of the water supply tube and the electric wire according to the present embodiment, the water supply tubes 51 and 52 are prevented from interfering with the wire harness 53 in the advance and retreat operation of the nozzle. Deformation due to contact from 52 is prevented. Note that the upstream curved portion 51a of the unit water supply tube 51 is positioned above the held members 52 and 53 during the nozzle advancing and retreating operation, so that it does not interfere with the held members 52 and 53. FIG.

A comparative example with respect to the wiring mode of the water supply tube and the electric wire according to the present embodiment as described above will be described. As shown in FIG. 21, in this embodiment, regarding the water supply tube and the electric wire, focusing on the portion located on the rear side of the nozzle unit 15, the wire harness 53 (the second wiring portion 53b thereof) is sequentially arranged from the rear side to the front side. , the unit water supply tube 51 (the downstream curved portion 51c thereof), and the nozzle cleaning tube 52 (the upstream curved portion 52a thereof) are located.

On the other hand, in the configuration of the comparative example, as shown in FIGS. 22 and 23 , the water supply tube is positioned behind the wire harness 53 . That is, in the configuration of the first comparative example shown in FIG. 22A , the unit water supply tube 51 has the downstream curved portion 51 c wrapped around the wire harness 53 from the rear side and connected to the connection block portion 58 . Accordingly, in the configuration of the first comparative example, focusing on the rear side of the nozzle unit 15, the unit water supply tube 51, the wire harness 53, and the nozzle cleaning tube 52 are positioned in order from the rear side to the front side. are doing.

In addition, in the configuration of the second comparative example shown in FIG. 23A, the unit water supply tube 51 has the downstream curved portion 51c wrapped around from the rear side of the wire harness 53, connected to the connection block portion 58, and used for nozzle cleaning. The tube 52 wraps the upstream curved portion 52 a from the rear side of the wire harness 53 and connects it to the connection block portion 58 . As a result, in the configuration of the second comparative example, focusing on the portion positioned on the rear side of the nozzle unit 15, the unit water supply tube 51, the nozzle cleaning tube 52, and the wire harness 53 are positioned in order from the rear side to the front side. are doing.

According to the configurations of these comparative examples, as shown in FIGS. 22 and 23, the water supply tubes 51 and 52 interfere with the wire harness 53 and the wire harness 53 comes into contact with the water supply tubes 51 and 52 during the nozzle advance/retreat operation. It will be deformed by receiving 22 and 23, similarly to FIG. 21, each state of a nozzle housed state, a nozzle intermediate state, and a nozzle protruded state is shown.

In the case of the configuration of the first comparative example, in the forward movement of the nozzle, the unit water supply tube 51 moves the downstream end connected to the connection block portion 58 forward, so that the wire harness 53 located on the front side moves forward. contact from the rear side. Specifically, as shown in FIGS. 22B and 22C, in the nozzle advancing operation, the unit water supply tube 51 contacts the wire harness 53 in such a manner that it is pulled forward or leftward (in FIGS. 22B and 22C, See the site indicated by symbol P1.). As a result, the curved portion of the rear portion of the wire harness 53 is crushed, and the wire harness 53 is deformed so that the bending R of the curved shape is reduced (see the portion indicated by P2 in FIGS. 22B and 22).

Since the wire harness 53 receives interference from the unit water supply tube 51 in this way, the contact portion of the wire harness 53 with the unit water supply tube 51 may be bent, deformed, worn, etc. due to repeated forward and backward movement of the nozzle due to long-term use. easily deteriorated by In particular, a portion of the wire harness 53 where the bending R is small may break due to long-term use.

Further, in the case of the configuration of the second comparative example, the nozzle cleaning tube 52, which is located on the inner peripheral side of the unit water supply tube 51 in the nozzle housed state and is located on the rear side of the wire harness 53, is the main part of the nozzle advancing operation. will interfere with the wire harness 53 . Specifically, as shown in FIGS. 23B and 23C , in the nozzle advancing operation, the nozzle cleaning tube 52 comes into contact with the wire harness 53 from the rear side, and then the wire harness moves forward as the nozzle 31 advances. It acts to pull 53 forward. As a result, the curved portion of the rear portion of the wire harness 53 is crushed, and the wire harness 53 is deformed so that the bending R of the curved shape is reduced (see the portion indicated by symbol Q1 in FIGS. 23B and 23C).

Even when the wire harness 53 is thus interfered with by the nozzle cleaning tube 52, the contact portion of the wire harness 53 with the nozzle cleaning tube 52 is not affected in the same manner as in the configuration of the first comparative example described above. is likely to deteriorate, and there is a possibility that disconnection will occur particularly at a portion where the bending R is small.

In contrast to the configuration of the comparative example as described above, according to the sanitary washing device 2 of the present embodiment, the wire harness 53 is not deformed by the water supply tubes 51 and 52, so the second wiring portion 53b of the wire harness 53 is , the nozzle can be advanced and retracted while maintaining a curved state in which the bending R is large in the nozzle housed state. As a result, deterioration of the wire harness 53 can be suppressed, and the risk of disconnection can be avoided. It should be noted that, according to the mode of handling the wire harness 53 by the first harness holding portion 110 and the like in the present embodiment, the second wiring portion 53b, which is the nozzle interlocking portion, has a relatively large bending R while achieving space saving. A lateral curvature can be formed.

According to such a configuration, it is possible to prevent the nozzle cleaning tube 52 held by the tube holding portion 102 and the wire harness 53 held by the wire holding portion 103 from interfering with each other. As a result, even when the nozzle cleaning tube 52 and the wire harness 53 are arranged close to each other, they can be prevented from interfering with each other, which contributes to downsizing of the apparatus. .

Regarding the support plate portion 131, if the extension length to the rear side is too long, the wire harness 53 may interfere with the support plate portion 131 during the forward movement of the nozzle. For this reason, it is preferable that the support plate portion 131 is provided at a substantially central portion of the nozzle 31 with a length dimension of about 1/3 to 1/4 of the length of the nozzle 31 in the nozzle inclination direction.

Further, in the sanitary washing device 2 of the present embodiment, the nozzle support 34 includes an engaging piece portion 151 which is provided on the left side of the nozzle 31 and engages with a locking projecting piece portion 153 provided on the base plate 5a; It has a fitting plate portion 152 that fits into a fitting groove portion 154 provided in 5a.

According to such a configuration, since there is a fitting structure by the fitting plate portion 152, in the fixing structure of the nozzle support 34 to the base plate 5a, the engaging portion by the engaging piece portion 151 can be made one. As a result, the nozzle support 34 can be easily removed from the base plate 5a compared to a configuration in which, for example, two engaging portions are provided on the left and right sides of the nozzle 31. can improve sexuality. As a result, maintainability of the nozzle unit 15 can be improved.

In addition, since there is a fitting structure with the fitting plate portion 152, even if there is only one engagement portion with the engagement piece portion 151, the nozzle unit 15 is firmly attached to the base plate without causing the nozzle support 34 to rattle. 5a. In particular, in the present embodiment, since the fitting plate portion 152 is provided in the vicinity of the engaging piece portion 151, rattling of the nozzle support body 34 can be effectively prevented. In addition, the fitting plate portion 152 is provided on the rear side of the center of the nozzle support 34 in the front-rear direction. Therefore, in the configuration in which the nozzle 31 is provided in a forward inclined shape, the height of the fitting plate portion 152 can be increased, and the fitting depth with respect to the fitting groove portion 154 can be increased. rattling can be effectively prevented.

Furthermore, in the present embodiment, the engagement portion by the engagement piece portion 151 is provided on the side where the held members 52 and 53 are arranged, that is, on the left side with respect to the nozzle 31 in the left-right direction. According to such a configuration, the arrangement space of the held members 52 and 53 can be adjusted by using a tool such as a flat-blade screwdriver to engage the engaging piece 151 and the locking projecting piece 153 when removing the nozzle unit 15 . It can be effectively used as a work space for the work to release. Further, for example, when two engaging portions are provided on the left and right sides of the nozzle 31, it is necessary to secure the above working space between the nozzle 31 and the hot air drying unit 46. is provided only on one side of the nozzle 31, the work space may be secured only on one side of the nozzle 31 on the left and right sides.
