In other words, when the slide portion 132 and the nozzle head cover 170 are integrated, when viewed from the rear end side in the A-axis direction, the slide portion 132 and the nozzle head cover 170 are substantially ring-shaped. An engaging extension 171 that extends in the direction opposite to the A-axis direction is provided at the lower part of the back surface of the tip of the nozzle head cover 170. The engagement extension portion 171 suppresses the rotation of the nozzle head cover 170 by fitting into the engagement recess 138 of the slide portion 132. Moreover, since the engagement extension part 171 becomes a form which receives the engagement recessed part 138, it is suppressed that the slide part 132 containing the engagement recessed part 138 falls below with a hydraulic pressure.

  As shown in FIG. 3, one substantially elliptical opening 166 is provided in the upper peripheral surface of the nozzle head cover 170 so as not to interfere with water ejected from the water discharge ports 102, 104, 106. The opening 166 not only prevents interference with water, but also facilitates alignment of the nozzle head cover 170 with respect to the nozzle head 160.

  Returning to FIG. 6, from the rear end portion of the nozzle head cover 170 on the nozzle body portion 110 side, an inlay portion 172 as an insertion portion inserted into the nozzle body portion 110 extends. The inlay portion 172 has a structure in which the outer diameter is smaller than the outer diameter of the nozzle head cover 170 excluding the inlay portion 172 and enters the inside of the nozzle body cover 130 of the nozzle body portion 110.

  A concave portion 174 that is concave when viewed from the rear end in the A-axis direction is formed on the outer peripheral surface of the inlay portion 172. Of the bottoms of the recesses 174, only the bottom on the A-axis direction side penetrates in the plate thickness direction, and a hook receiving hole 142B into which the hook 142A is fitted is formed by this through hole. The hook receiving hole 142B is a part of the lock portion 142, and locks the nozzle main body portion 110 and the nozzle head portion 150 by fitting the hook 142A. The hook 142A is stronger than the surroundings of the hook receiving hole 142B, and even when the holding strength (lock strength) is reduced due to repeated attachment and detachment operations, the holding strength is restored if only the nozzle head portion 150 is replaced. .

  In addition, a region of the rear end portion of the nozzle head cover 170 around the spigot portion 172 is an operation portion 178 that at least partially moves when the push operation is performed to unlock the lock portion 142. The region of the operation unit 178 is indicated by a dotted line in FIG. 6, but the shape and size are not limited.

  The operation unit 178 is formed at a part of the peripheral side surface at the rear end portion of the nozzle head cover 170, and between the inner peripheral surface of the nozzle head cover 170 and the outer peripheral surface of the nozzle head 160 located at a part thereof. A gap D is formed. As a result, when the operation unit 178 is pushed in, the operation unit 178 is elastically deformed toward the gap D, so that at least a part of the operation unit 178 moves.

  The operation unit 178 is substantially flush with the periphery of the operation unit 178 in the nozzle head cover 170.

  The packing 190 of the nozzle head unit 150 is provided to prevent water leakage. The packing 190 is plate-shaped and contacts the rear end surface of the nozzle head 160. Further, the packing 190 is fixed to the nozzle head 160 by a hook-like engagement convex portion 164 in order to prevent the packing 190 from dropping and losing when the nozzle head portion 150 is detached. Further, by being fixed to the nozzle head 160, the packing 190 can be removed together when the nozzle head 160 is removed.

---- Action ---
Next, the effect | action which concerns on 1st embodiment of this invention is demonstrated.

---- When the nozzle head unit 150 is attached ---
First, the action when the nozzle head unit 150 is attached (connected) to the nozzle body 110 will be described in detail.

  As shown in FIG. 4, the user holds the nozzle head unit 150 with a finger or the like. Then, the user places the nozzle head part 150 on the tip side of the slide part 132 of the nozzle main body part 110. Thereafter, using the slide portion 132, the nozzle head portion 150 is slid to the lock location (location of the hook 142A).

  In the process of sliding on the slide part 132, the nozzle head part 150 is guided to the lock position with the nozzle body part 110 by the two rail bases 162 engaging with the guide parts 134A and 134B. Then, with the momentum of the slide, the hook 142A temporarily bends outward and enters the recess 174, and then fits into the hook receiving hole 142B to lock the nozzle body 110 and the nozzle head 150.

  As described above, the nozzle head unit 150 is attached to the nozzle main body 110 by two operations of gripping and sliding.

  Here, since the attachment of the nozzle head unit 150 can be locked by one operation of sliding, a series of work efficiency up to the locking can be improved. Further, the presence of the slide portion 132 can suppress the displacement of the nozzle head portion 150 when the nozzle head portion 150 starts to be connected to the nozzle main body portion 110, compared to the case where the slide portion 132 is not provided. The nozzle head part 150 and the nozzle body part 110 can be easily connected.

  As shown in FIG. 6, the rail base 162 is provided at a part on the tip side of the nozzle head 160 so that when the nozzle head portion 150 is placed on the slide portion 132, it engages with the guide portions 134A and 134B. The nozzle head portion 150 and the nozzle body portion 110 are aligned by engaging the guide portions 134A and 134B and the rail base 162 in the course of the slide. Can do.

  In the sliding process, the movements other than the A-axis direction are restricted by the engagement between the guide portions 134A and 134B and the rail base 162 (also serving as a guide groove), and for example, shifting in the vertical and horizontal directions and the rotation direction can be suppressed. Further, when the nozzle head unit 150 is slid in a state where the guide units 134A and 134B and the rail base 162 are not engaged, the nozzle body cover 130 is connected before the nozzle body unit 110 and the nozzle head unit 150 are connected. Since the peripheral edge portion of the nozzle and the peripheral edge portion of the nozzle head cover 170 interfere with each other and cannot be connected, erroneous mounting is prevented.

  Further, since the nozzle body 120 has the ribs 126A and 126B, before the packing 190 is connected to the nozzle body part 110, the nozzle body part 110 and the nozzle head part 150 are both positioned in the sliding process. Can do. In FIG. 4, the packing 190 is connected to the nozzle main body 110 in the state before sliding, but the nozzle main body 110 and the nozzle head 150 can be connected even in this case.

--- When removing the nozzle head section 150 ---
Next, the action when the nozzle head part 150 is detached from the nozzle body part 110 will be described in detail.

  7A and 7B are enlarged perspective views of the tip portion of the nozzle 100, where FIG. 7A shows a state before the nozzle head unit 150 is removed, and FIG. 7B shows a state after the nozzle head unit 150 is removed.

  As shown in FIG. 7A, the user holds the nozzle head unit 150 with a finger or the like. At this time, the operator grips the operation unit 178 with the thumb belly or the like. The user then pushes the operation unit 178 radially inward (in the direction of the arrow in the figure) with the belly of the finger in contact with the operation unit 178 while holding the nozzle head unit 150. As a result, the operating portion 178 is elastically deformed and at least a part thereof moves inward, and the hook receiving hole 142B provided in the nozzle head portion 150 also moves inward. As a result, the engagement with the hook 142A is released, and the lock between the nozzle body 110 and the nozzle head 150 is released.

  Next, as shown in FIG. 7B, the user pulls out the nozzle head portion 150 in the A-axis direction along the slide portion 132 while holding the nozzle head portion 150 and in the pushing operation state.

  As described above, the nozzle head portion 150 is removed from the nozzle body portion 110 by the three operations of gripping, pushing operation, and drawing.

--- Effect ---
Next, the effect which concerns on 1st embodiment of this invention is demonstrated.

  According to the sanitary washing apparatus 20 according to the first embodiment of the present invention, since the nozzle 100 includes the operation unit 178 that is at least partially moved by being pushed in and releases the lock of the lock unit 142, the lock unit When the nozzle head unit 150 and the nozzle body unit 110 are locked with the nozzle 142, the nozzle unit 150 is pushed into the operation unit 178 even if the nozzle head unit 150 is rotated or pulled. If there is no operation, the lock is not released. In addition, when cleaning is performed in which the rotation operation is performed by grasping the nozzle 100 with a cloth or the like, a pressing operation that contacts the nozzle head unit 150 before the rotation may be assumed, but at least a part of the operation unit 178 moves. Unless the pushing operation is performed with a larger force, that is, the pushing operation, the operation unit 178 does not move and the lock is not released. In the case of cleaning or the like, it may be assumed that the operation unit 178 is pushed in. However, according to the configuration of the first embodiment, the lock is inadvertently released by at least a rotation operation or a pulling operation. Can be suppressed.

  Note that, when the operation unit 178 is not pushed in, the nozzle head unit 150 and the nozzle body unit 110 are in a locked state. For example, the water pressure is received by the water injection from the nozzle 100. The nozzle head unit 150 is stably held against the axial force.

  In addition, since the operation unit 178 is provided in a part of the nozzle 100, even if a pressing operation is performed on any part of the nozzle 100 except the operation unit 178, the operation unit 178 is provided in a part of the nozzle 100. The operating portion 178 is reduced in force so that no pushing force is applied or the pushing force is dispersed and the operating portion 178 does not move. With such a force, the operation unit 178 does not move and the lock is not released. Therefore, according to the structure of 1st embodiment, it can suppress that a lock | rock will be cancelled | released carelessly by pushing operation.

Moreover, since the operation part 178 is provided in the peripheral side surface of the nozzle 100, when releasing a lock | rock, pushing operation is carried out to radial direction. Therefore, even if there is an operation of pushing the nozzle in the axial direction (including a push-in operation) or a pulling operation, the push-in operation is not performed in the radial direction, so that it is possible to further prevent the lock from being inadvertently released. it can.
Further, when the peripheral side surface is picked in order to pull out the nozzle head unit 150 from the nozzle main body 110, the operation unit 178 provided on the peripheral side surface is pushed in at that time, or the peripheral side surface around the portion to be picked The pushing force acts on the, and the lock can be released. Therefore, the working efficiency when pulling out the nozzle head unit 150 can be improved.

  Further, since the operation unit 178 is elastically deformed by a pushing operation, the lock can be released with a simple structure as compared with the case where the operation unit 178 is a push button protruding from the nozzle 100 as described later, for example. Further, since the operation unit 178 moves while being elastically deformed, the operation unit 178 is elastically deformed in the reverse direction and returned to the original position after the pushing operation is finished, so that the nozzle head unit 150 is used again. be able to.

  In addition, since the operation unit 178 is substantially flush with the periphery of the operation unit 178 in the nozzle head unit 150, the operation unit 178 is not noticeable as compared with a case where the operation unit 178 is uneven and not substantially flush with the periphery of the operation unit 178, for example. However, local contamination can be suppressed.

  Further, when the peripheral side surface of the nozzle head unit 150 is picked in order to pull out the nozzle head unit 150 from the nozzle body unit 110, the operation unit 178 is provided on the nozzle head unit 150 to be pulled out, so that the operation unit 178 is grasped. be able to. Therefore, if the operation unit 178 is grasped, the push-in operation and the pull-out operation can be performed by a series of operations without releasing the hand, so that the working efficiency when pulling out the nozzle head unit 150 can be improved.

  Further, since the operation portion 178 is provided at the rear end portion of the nozzle head portion 150, it is more easily elastically deformed than when the operation portion is not at the end portion.

  Further, since the lock portion 142 has a configuration of the hook 142A and the hook receiving hole 142B, the hook 142A fits into the hook receiving hole 142B simply by inserting the nozzle head portion 150 into the nozzle main body portion 110, and the nozzle main body portion 110 and the nozzle head. The part 150 can be locked. The hook receiving hole 142B of the lock portion 142 is provided at the same end as the operation portion 178, so that when the operation portion 178 is pushed in, the hook receiving hole 142B is easily moved to release the lock. Can do.

  Further, since the hook receiving hole 142B is provided in the inlay portion 172, in a state where the inlay portion 172 is inserted into the nozzle body 110, that is, in a state in which the nozzle 100 is assembled, the penetrating hook receiving hole 142B is formed. Since it is hidden inside, the hook receiving hole 142B is less likely to get dirty and the nozzle 100 is easier to clean than when the penetrating hook receiving hole 142B is exposed to the outside.

  In addition, since the nozzle main body 110 of the nozzle 100 includes the slide portion 132, after the nozzle head portion 150 is placed on the slide portion 132 and then slid to the locked position, the hook 142 </ b> A is quickly moved to the hook receiving hole. The nozzle body part 110 and the nozzle head part 150 can be locked by fitting into 142B. Therefore, a series of work efficiency up to the lock can be improved. Further, when the nozzle head unit 150 is started to be connected to the nozzle main body unit 110 as compared with the case where the slide unit 132 is not provided, it is possible to suppress the displacement of the nozzle head unit 150, and thus the nozzle head unit 150 and the nozzle main body. Connection of the unit 110 can be facilitated. Further, when the nozzle head portion 150 is removed, the slide portion 132 can be slid and pulled out while receiving the nozzle head portion 150 after the lock is released by pushing operation. 12 can be suppressed from falling.

  Further, since the detachable nozzle head section 150 includes not only the nozzle head cover 170 but also the nozzle head 160 itself, the head head 160 can be removed without removing the entire nozzle 100 when cleaning the flow path through which water flows. Together with the nozzle head cover 170, it can be removed from the nozzle body 110, and the working efficiency during cleaning can be improved.

  Further, since the slide part 132 extends from the lower part of the outer periphery of one end of the nozzle body part 110, the nozzle head part 150 can be put on the slide part 132 without removing the nozzle body part 110.

  Further, since the slide portion 132 extends in the extending direction of the central axis O of the nozzle main body 110, sliding is easier than in the case where the slide portion 132 extends obliquely from the central axis O of the nozzle main body 110.

  Further, when the nozzle head portion 150 is placed on the slide portion 132 and slid to the lock portion with the nozzle main body portion 110, the guide portions 134A and 134B are provided to further prevent the nozzle head portion 150 from being displaced. can do. Further, since the guide portions 134A and 134B are rail-shaped, the nozzle head portion 150 can be guided to the lock location only by sliding in one direction, and the shift of the guide can be suppressed.

  A first recess 706 </ b> A is provided at the tip of the peripheral side surface of the nozzle body 110. Further, a second recessed portion 706B narrower than the first recessed portion 706A is provided on the side opposite to the first recessed portion 706A at the peripheral side end portion of the nozzle main body 110.

  Further, guide portions 708A and 708B having shapes different from those of the guide portions 134A and 134B are provided at both end portions along the A-axis direction of the slide portion 132 of the nozzle body cover 130. Each of the guide portions 708A and 708B has a rail shape, but protrudes from the both end portions in the circumferential direction of the nozzle body cover 130. Further, the guide portions 708A and 708B are thinner than the both end portions, respectively, and a step is formed between the guide portions 708A and 708B and the both end portions inside the nozzle body cover 130. Each of the guide portions 708A and 708B continues straight from the rear end of the slide portion 132 to the tip end of the slide portion 132 along the A-axis direction.

  Protruding plates 710A and 710B are provided at the back of the guide portions 708A and 708B in the nozzle body cover 130, respectively. The projecting plates 710 </ b> A and 710 </ b> B project straight from the inner peripheral surface of the nozzle body cover 130 toward the inside. The protruding plate 710A enters the first recess 706A, and the protruding plate 710B fits into the second recess 706B.

  In addition, projecting plates 712A and 712B are provided on the inner peripheral surface of the nozzle body cover 130 near the guide portions 708A and 708B. The projecting plates 712A and 712B project straight upward from the inner peripheral surface.
