15 is a detailed view illustrating the operation sequence of the drive switching unit of the washing nozzle driving apparatus of the bidet according to the present invention in detail, the first nozzle 120 is reversed to drive belt 80 A process of being separated and driving coupled with the second nozzle 130 is shown.

First, in the step (s1), when the stepping motor (not shown) rotates in the clockwise direction and the second drive gear 60 rotates in the clockwise direction 200, the drive engaged with the second drive gear 60 is performed. The upper portion of the belt 80 is driven in the reverse direction 300a, and is formed at the rear end of the first nozzle 120 on an outer tooth 82 formed in a predetermined number on the outer portion of the driving belt 80. Engagement with the teeth 123 and the tooth valleys of the belt engaging rack is driven in the reverse direction. At this time, the spring mounting protrusion 103 formed at the upper end of the switching cam 100 is inserted into the cam guide groove 32 formed at the top of the cover, and the switching spring 40 is the spring mounting protrusion 103 formed at the switching cam 100. And it is attached to the spring hook 31 formed on the upper cover, the spring mounting projection 103 of the switching cam 100 to the one side of the cam guide groove 32 so as not to move the switching cam.

At this time, the second nozzle 130 is stopped and spaced apart from the outer tooth 82 formed on the driving belt 80, and furthermore, the first sliding protrusion 134 formed at the rear end of the second nozzle 130 is the base ( 140, the driving in the front-rear direction is limited because it is inserted between the second locking jaw 146b and the second stopper 147b formed at the rear end.

In the step S3 of FIG. 16, the stepping motor (not shown) is rotated one step further in the clockwise direction in the step S2. When the second drive gear 60 rotates in the clockwise direction, the second step is performed. The first of the outer teeth 82 formed in a predetermined number on the outer side of the drive belt 80 meshed with the drive gear 60 fits the cam gear 102 formed on the outer side of the switching cam 100. The first nozzle 120 is further driven in a state of being bitten by the outer tooth 82 of the driving belt, and the second nozzle 130 is shown in the figure (S1). ), And is stopped and spaced apart from the outer tooth 82 formed in the drive belt 80, the first sliding projection 134 formed on the rear end of the second nozzle 130 is formed on the rear end of the base 140 It is inserted between the second catching jaw 146b and the second stopper 147b, so that driving in the front-rear direction is restricted.

When the second drive gear 60 is rotated one step further in the clockwise direction 400 in the state of FIG. 16 in the state of FIG. 16 (s2), the outer tooth 82 formed on the outer side of the driving belt 80 is rotated. Is separated from the belt coupling rack 123 of the first nozzle 120, the reverse of the first nozzle 120 is stopped. On the other hand, the outer tooth 82 formed on the drive belt 80 meshes with the cam gear 102 of the switching cam, and rotates the switching cam 100 in the counterclockwise direction 400 so as to lower the lower end of the switching cam 100. Rotate the eccentric cam 104 formed in the counterclockwise direction (400). At this time, the switching spring 40 transitions to a state in which the spring mounting protrusion 103 formed on the upper part of the switching cam is tensioned with each other by the spring hook 31 formed on the base, thereby preventing the rotation direction 400 of the cam. Tensile force acts. In addition, the eccentric cam 104 is inserted into the cam through hole 111 formed in the center of the switching plate 110 to push up the upper surface of the cam through hole 111, so that the whole of the switching plate 111 in the upper direction 500. Drive it. Therefore, the switching plate 111 is the first switching projection 112a formed in the front and rear direction of the first nozzle 120 in the upper and lower portions of the switching plate, and the first switching projection inserted into the first switching throat 112a. The upper end portion 127 of the first nozzle 120 is moved upward in the upper direction 500 so that the entire rear end portion of the first nozzle 120 moves in the first stopper (upper direction 500) and is formed on the opposite side of the first switching protrusion 127. The first sliding protrusion 124 is pushed between the first catching jaw 146a and the first stopper 147a formed at the rear end of the base 140.

On the other hand, the second switching projection 137 inserted in the forward second switching strut 112a formed in the forward and backward direction of the second nozzle 130 in the lower portion of the switching plate 111 is pushed in the upward direction 500. Raise, and eventually, the entire rear end of the second nozzle 130 is moved in the upper direction 500, so that the belt coupling rack 133 formed at the rear end of the second nozzle 130 is located on the upper side of the driving belt 80. Move a certain distance to the side.

In step (s4) of FIG. 16, the stepping motor (not shown) is rotated one step further clockwise in step (s3). When the second drive gear 60 rotates clockwise (200), the switching is performed. At the same time, the holding force of the spring 40 is changed to a direction supporting the rotation of the switching cam 100, and at the same time, the eccentric cam 104 further rotates the counterclockwise direction 500 to move the switching plate 110 upward. The first switching projections 127 and the first switching slits 112a and the second switching slits 112b formed at the rear ends of the first nozzles 120, respectively; Each of the second switching protrusions 137 formed at the rear end of the two nozzles 130 is pushed up, so that the belt engaging rack 123 formed at the rear end of the first nozzle is spaced farther from the driving belt 80 and the second nozzle ( 130) the belt engaging rack 133 formed at the rear end is moved closer to the drive belt (80) side.

In the step (s5) of FIG. 16, the stepping motor (not shown) is rotated one step further in the clockwise direction in the step (s4), and is switched when the second drive gear 60 is rotated in the clockwise direction (200). Since the cam 100 pushes up the switching cam 110 further upward, the first switching slits 112a and the second switching slits 112b are formed at the rear end of the first nozzle 120. The second switching protrusion 137 formed at the rear end of the protrusion 127 and the second nozzle 130 is pushed up, respectively, so that the belt engaging rack 123 formed at the rear end of the first nozzle is spaced farther from the driving belt 80. At the same time, the first sliding protrusion 124 formed on the opposite side of the first switching protrusion 127 is pushed between the first catching jaw 146a and the first stopper 147a formed at the rear end of the base 140.

Accordingly, the first nozzle 120 is spaced apart from the driving belt 80 to terminate the reverse driving, while the first sliding protrusion 124 formed at the rear end of the first nozzle 120 is formed at the rear of the base 140. Since the driving in the front-rear direction is restrained between the first locking jaw 146a and the first stopper 147a, the first nozzle 120 is moved forward and backward by the external force other than the driving force of the driving belt 80. To restrain it from moving.

Meanwhile, the belt coupling rack 133 formed at the rear end of the second nozzle 130 moves closer to the driving belt 80, and the first outer tooth 82 formed outside the driving belt 80 is the second nozzle 130. The second nozzle 130 starts to move forward by the driving force of the driving belt 80 while being engaged with the first bone 123b of the belt engaging rack 133 formed at the rear end.

In step (s6) of FIG. 16, the stepping motor (not shown) is rotated one step further clockwise in step (s5). When the second drive gear 60 rotates clockwise (200), the driving belt Since the outer tooth 82 formed in the cam gear is out of the cam gear formed on a part of the outer circumference of the switching cam 100, the cam gear stops rotating in the counterclockwise direction 500, and the spring weight protrusion formed on the switching cam 100 is upper. 103 is anchored and fixed to one side of the cam guide groove 32 formed in the upper portion of the base 30 by an anchoring switching spring 40. At this time, the second nozzle 130 is completely engaged by the outer tooth 82 of the driving belt 80, and is advanced along the second guide groove 148b formed in the base, so that the second washing water inlet pipe 131a ) Continues to move forward until it stops and restrains against the second nozzle stopper 148d at the end of the second guide groove 148b. When driving the advanced second nozzle 130 to the backward position, the control circuit (not shown) based on the predetermined position that is restrained by the second nozzle stopper (148d) position and stopped. Since the first nozzle and the second nozzle 130 can be positioned in the reverse position by applying the stepping motor 10 through the first nozzle 120 and the first nozzle 120, the washing nozzle driving apparatus of the bidet according to the present invention. Means for sensing the position relative to the two nozzles 130 are not required separately.

In the above, while the first nozzle 120 is driven in the reverse direction, the process of driving the drive belt 80 to the second nozzle side has been described in detail. On the contrary, while the second nozzle 130 is driven in the reverse direction, the driving belt 80 is driven to the first nozzle side, and the rotation direction and the driving direction of each nozzle are reversed.

In addition, when either nozzle is coupled to the drive belt and driven, the nozzle, once engaged with the drive belt 80, is a stepping motor (not shown) by a separate stepping motor 10 control circuit (not shown). 10) can be moved forward or backward in accordance with the rotation direction of the stepping motor 10, and can be stopped at a predetermined position, so that the user using the bidet can advance the desired nozzle to perform cleaning or cleaning, and also Of course, it can be stopped and moved back and forth by a predetermined distance from the desired position to the desired position.

Washing nozzle driving apparatus of the bidet according to the present invention, it is possible to selectively move the first nozzle 120 or the second nozzle 130 with one stepping motor 10, the reverse of the separate stepping motor 10 By a control circuit (not shown) and a control program (not shown), a desired nozzle can be stopped at a desired position at a desired position, and the nozzle can be moved forward or backward by a predetermined distance from the predetermined position, which is very effective. In addition, since the propulsion force of the nozzle does not depend on the water pressure of the separate washing water itself, there is no loss of the washing water pressure and there is no leakage of the washing water in the propulsion method of the nozzle by the washing water pressure. In addition, since the position of the first nozzle 120 or the second nozzle 130 can be selectively moved forward or backward to a desired position without having a separate position sensor, manufacturing cost can be significantly reduced, respectively. Since the nozzles are located very close to each other, the direction in which the nozzle proceeds and the angle formed with the central part of the toilet are relatively small, so that an injection error for the user's washing part is reduced. In addition, the washing nozzle driving apparatus of the bidet according to the present invention may be installed in the bidet so that the two nozzles are positioned to the left and right, it may be used to be positioned up and down.
