[0041] Referring to FIGS. 1 to 9, a nozzle drive device 10 for a bidet includes a nozzle cover 100, a nozzle fixing part 200, an extended nozzle part 300, a spray nozzle part 400, and a driving part 500.

[0042] The nozzle cover 100 is mounted on a water supply part to which a water supply source is connected. In this case, a nozzle coupling part may be installed at one outer surface of the nozzle cover 100 so that each nozzle is coupled.

[0043] Accordingly, it is possible to prevent the nozzles from getting tangled, to see the positions and roles of the nozzles (the functions can be determined through color, shape, and coupling positional relationship), and to quickly and simply replace nozzles that are damaged (due to breakage, contamination with rust, etc.).

[0044] The nozzle fixing part 200 is coupled to the inside of the nozzle cover 100. In addition, the nozzle fixing part 200 is formed with an incision groove 210 in which a part of a surface is incised along a vertical length.

[0045] In this case, the incision groove 210 may be formed with a first fixing groove (not shown), so that a moving protrusion 410 is able to fix the extended nozzle part 300 withdrawn from the nozzle fixing part 200.

[0046] In addition, the incision groove 210 may be formed with a second fixing groove (not shown), so that the moving protrusion 410 is able to fix the spray nozzle part 400 withdrawn from the extended nozzle part 300.

[0047] In addition, the nozzle fixing part 200 may include a fixing member 220. The fixing member 220 may be formed with a groove corresponding to the incision groove 210 and fix the extended nozzle part 300 and the spray nozzle part 400.

[0048] The fixing member 220 may further include a first fixing member 221 and a second fixing member 222. Here, a lower end of the extended nozzle part 300 may be coupled to the first fixing member 221. Also, a loser end of the spray nozzle part 400 may be coupled to the second fixing member 222.

[0049] In addition, in the first fixing member 221, a coupling protrusion may be formed so as to be engaged with and coupled to the inside of the second fixing member 222, and a protruding protrusion 402 protruding from a lower surface of the spray nozzle part 400 toward the extended nozzle part 300 may be inserted into a corresponding groove corresponding to the protruding protrusion 402.

[0050] In addition, the second fixing member 222 may be formed with an insertion hole 222a into which the coupling protrusion is inserted, and a lower end of the spray nozzle may be inserted into a groove formed in an outer circumference of the second fixing member 222.

[0051] The extended nozzle part 300 is slidably coupled to the inside of the nozzle fixing part 200, and simultaneously communicates with a base end of the nozzle cover 100 and a front end of the nozzle cover 100.

[0052] In addition, the extended nozzle part 300 may be formed with a corresponding incision groove 310 corresponding to the incision groove 210 of the nozzle fixing part 200, and the extended nozzle part 300 may include a sliding protrusion 320 formed in a lower end of an outer circumference of the extended nozzle part 300 and capable of moving in a sliding manner.

[0053] The spray nozzle part 400 is coupled to the inside of the extended nozzle part 300 to be slidably movable toward an upper end of the extended nozzle part 300, and a nozzle connected to a water supply part is coupled to the spray nozzle part 400, so that at least one spray hole 401 is formed to spray wash water to the outside of the spray nozzle part 400.

[0054] In addition, the spray nozzle part 400 may include a moving protrusion 410 protruding from the outer circumferential surface of the lower end of the spray nozzle part 400. In this case, the moving protrusion 410 may slide along the incision groove 210 and the corresponding incision groove 310. In addition, the moving protrusion 410 protrudes in both directions and has an elastic force, so that the moving protrusion 410 can be fitted into the first fixing groove and the second fixing groove described above.

[0055] The driving part 500 includes a wound member 510 coupled to an outside of the nozzle cover 100, the wound member 510 being rotated so as to draw and insert the extended nozzle part 300 and the spray nozzle part 400 in multiple stages.

[0056] Here, the wound member 510 has a plate spring 520 wound therein. One side of the plate spring 520 is formed with a hole 521 and coupled to the moving protrusion 410. The other side of the plate spring 520 is partially wound inside the wound member 510, so that a part of the plate spring 520 coupled to the moving protrusion 410 is wound and unwound according to driving of the driving part 500.

[0057] In addition, the driving part 500 may be used as a motor. Since the motor is a well-known technology, a detailed description thereof will be omitted.

[0058] Meanwhile, the nozzle drive device 10 for a bidet may include a flow rate regulating vale 600 coupled the water supply part to regulate a flow rate.

[0059] In this case, the flow rate regulating valve 600 is formed with a plurality of bearings. As the plurality of bearings, a coupling bearing, an elastic part, a rotation restraint, etc. may be installed.

[0060] Therefore, the nozzle drive device for a bidet 10 according to the present disclosure allows a washing nozzle to be positioned at a pressurized location when a user is seated, so that even when the user's seated position is changed, it is possible to accurately vary a location where to spray wash water. Thus, there is no cumbersome to readjust the position of the nozzle and the wash water can be sprayed accurately to the pressurized location, thereby securing accuracy.

[0061] In addition, by having the bidet nozzle and the washing nozzle have a three-stage structure so that they can be supported with a single support structure, the overall size of the bidet structure can be significantly reduced, making it easy to secure space in the toilet and at the same time facilitate installation work.

[0062] As the present disclosure may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described examples are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
