Description BIDET

Technical Field

[1] The present invention relates, in general, to a bidet and, more particularly, to a bidet, which has a shower function, has an antibacterial silicone hose for insertion into the bowels or the vagina to clean the interior of the bowels or the vagina, and uses tap water after purifying the water. Background Art

[2] Generally, a bidet is the basin that is mounted to the rear portion of a toilet for washing the genitals and the anal area. According to the recent tendency to emphasize cleanliness, the number of male and female users is gradually increasing.

[3] However, a conventional bidet has a drawback in that the bidet is mounted to a toilet, so that the bidet can be used to wash only a user's anal area. Particularly, the conventional bidet is constructed so that water (hereinafter, referred to as "washing water") is sprayed only under the anal area. Thus, the bidet can wash only the body part which is exposed to the outside, but cannot supply washing water to the interior of the bowels or the vagina, which must also be cleaned in practice. That is, the conventional bidet is problematic in that it is difficult to use to wash inside body cavities.

[4] Further, the conventional bidet is problematic in that it uses washing water supplied from a water pipe without additional treatment, and thus the cleanliness of the washing water is somewhat poor. Therefore, the cleaning effect is low. Disclosure of Invention Technical Problem

[5] Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a bidet, which is constructed for a user to hold the bidet with his or her hand and move the bidet close to the body part which is to be washed, thus allowing any body part to be washed.

[6] Another object of the present invention is to provide a bidet, which has a shower function, thus executing both a bidet function and a shower function.

[7] A further object of the present invention is to provide a bidet, which is constructed to include an antibacterial silicone hose for insertion into the bowels or vagina, thus washing the interior of the bowels or vagina.

[8] Yet another object of the present invention is to provide a bidet, which purifies tap water and uses the purified water, thus more thoroughly cleaning body parts. Technical Solution [9] In order to accomplish the objects, the present invention provides a bidet, including an inlet hose for introducing washing water; a filter including a filter chamber having an inlet connected to the inlet hose and used to supply washing water into the filter, and an outlet used to discharge washing water supplied into the inlet, and a filtering element received in the filter chamber to purify washing water supplied into the filter chamber; a head detachably fastened to the filter, and having at least one shower nozzle and bidet nozzle which are coupled to the outlet of the filter chamber to spray washing water; and a control valve for supplying the washing water discharged from the outlet of the filter chamber to either the shower nozzle or the bidet nozzle.

[10] Preferably, the bidet nozzle includes a nozzle body mounted to the head and having an open front, and an antibacterial silicone hose disposed in the nozzle body, extended forwards from the open front of the nozzle body by pressure of washing water supplied into the nozzle body and inserted into a user's bowels or vagina, thus spraying washing water into the bowels or vagina.

[11] In this case, the bidet nozzle further includes a spring elastically compressing the antibacterial silicone hose in a direction of insertion of the antibacterial silicone hose into the nozzle body, thus returning the antibacterial silicone hose to an original position thereof.

[12] According to an aspect of this invention, the bidet nozzle includes a nozzle body mounted to the head, and having an open front; a vibrator casing fastened to a rear end of the nozzle body through a screw-type fastening method, with a vibrator provided in the vibrator casing; a spring mounted to a rear end of the vibrator, and absorbing vibrations of the vibrator; a vibration insert unit installed to extend outwards from the nozzle body, inserted into the bowels or vagina, and generating waves in washing water using the vibrations of the vibrator, prior to spraying the washing water; and a battery for supplying electricity to the vibrator.

[13] According to another aspect of this invention, the bidet nozzle includes a nozzle body mounted to the head, and having open front and rear portions; an antibacterial silicone hose disposed in the nozzle body, extended forwards by pressure of washing water supplied into the nozzle body and inserted into a user's bowels or vagina, thus spraying the washing water into the bowels or vagina; a spring elastically compressing the antibacterial silicone hose in a direction of insertion of the antibacterial silicone hose into the nozzle body, thus returning the antibacterial silicone hose to an original position thereof; and at least one telescopic movable pipe telescopically installed in the open rear portion of the nozzle body, and supporting a rear end of the antibacterial silicone hose, thus being inserted into the nozzle body when the antibacterial silicone hose is extended forwards. Advantageous Effects

[14] As described above, according to the present invention, a bidet is constructed so that a user can hold the bidet in his or her hand and move the bidet close to the body part which is to be washed, thus allowing any body part to be washed. The bidet has a shower function, so that no additional shower device is required. Further, the bidet is constructed to include an antibacterial silicone hose for insertion into the bowels or vagina, thus allowing the interior of the bowels or vagina to be more thoroughly cleaned. Furthermore, the bidet purifies tap water and uses the purified water, thus more thoroughly washing a desired body part. Further, the bidet washes the interior of the bowels or vagina using tap water which has been purified, thus completely preventing contaminants from being introduced into the body.

Best Mode for Carrying Out the Invention [24] Hereinafter, a bidet according to the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Mode for the Invention [25] Referring to FIGS. 1 and 2, the bidet according to the present invention is provided with an inlet hose 10 for introducing washing water into the bidet. The inlet hose 10 is made of flexible material, for example, synthetic resin or rubber, and is coupled to a coupling hose of a water pipe (not shown) or a shower device to introduce tap water, that is, washing water.

[26] Further, the bidet of the present invention is provided with a filter 20 which is connected to the inlet hose 10. The filter 20 has a filter housing 22, with a filter chamber 24 defined in the filter housing 22. The filter chamber 24 includes an inlet 24a which communicates with the inlet hose 10, and an outlet 24b which discharges the introduced washing water. Filtering elements 25 are accommodated in the filter chamber 24.

[27] Since the inlet 24a communicates with the inlet hose 10, washing water flowing in the inlet hose 10 is introduced into the filter chamber 24. In this case, a check valve 26 is mounted to the inlet 24a. The check valve 26 is a valve using a ball, and prevents washing water from flowing from the filter chamber 24 back into the inlet hose 10.

[28] The outlet 24b is used to discharge washing water from the inlet 24a and the filter chamber 24, and is provided in a cover plate 27 which covers the upper end of the filter chamber 24 to close the filter chamber. A post-processing filter 28 is mounted to the outlet 24b, thus secondarily filtering washing water which has passed through the filtering elements 25 in the filter chamber 24.

[29] The filtering elements 25 comprises activated carbon or a similar substance, and filters washing water passing through the filter chamber 24, thus providing very clean washing water. Meanwhile, according to the present embodiment, activated carbon is used as the filtering elements 25. However, the present invention may use any substance without being limited to activated carbon, as long as the substance filters the washing water.

[30] Turning back to FIGS. 1 and 2, the bidet according to the present invention is provided with a head 30 which is fastened to the upper portion of the filter 20 through a screw-type fastening method. The head 30 has a head body 32, with a shower nozzle 40 and a bidet nozzle 50 mounted to the head body 32.

[31] The shower nozzle 40 includes a nozzle body 42, and a nozzle plate 44 mounted to the front of the nozzle body 42. The nozzle body 42 and the nozzle plate 44 are fastened to the head body 32 by a screw 45.

[32] The shower nozzle 40 is coupled through a first coupling tube 46 to the outlet 24b of the filter chamber 24 of the filter 20. Thus, washing water fed from the filter chamber 24 can be sprayed outside via the nozzle plate 44. Especially, washing water is sprayed through the nozzle plate 44, thus allowing a user to take a shower. In this case, two or more shower nozzles 40 may be installed as necessary.

[33] The bidet nozzle 50 includes a nozzle body 52, and an antibacterial silicone hose 54 which is fitted into the nozzle body 52. The nozzle body 52 is a long tube, and is formed integrally along the back surface and the upper surface of the head body 32, so that the nozzle body 52 is bent into an "L" shape.

[34] The nozzle body 52 has an inner body 52a. The inner body 52a is coupled to the outlet 24b of the filter chamber 24 of the filter 20 via a second coupling tube 55. Thus, washing water passing through the filter chamber 24 is introduced into the nozzle body 52. Meanwhile, the inner body 52a is open at front and rear ends thereof. The open front end of the inner body 52a is capped by a water discharge cap 56 having a through hole 56a, and the open rear end of the inner body 52a is coupled to a cover 57.

[35] The antibacterial silicone hose 54 is inserted into a user's bowels or vagina, and is flexible. A passage 54a is defined in the antibacterial silicone hose 54, and a nozzle head 54c having nozzle holes 54b is provided on the front of the antibacterial silicone hose 54. Preferably, the nozzle head 54 is formed to have a conical shape.

[36] The antibacterial silicone hose 54 is movably inserted into the inner body 52a of the nozzle body 52. While the antibacterial silicone hose 54 is moved forwards to the open front end of the inner body 52a by the pressure of washing water introduced into the inner body 52a, the antibacterial silicone hose 54 protrudes forwards from the nozzle body 52. Meanwhile, washing water introduced into the inner body 52a flows into the passage 54a of the antibacterial silicone hose 54. The washing water is sprayed outside through the nozzle holes 54b of the nozzle head 54c.

[37] The antibacterial silicone hose 54 protrudes forwards and sprays washing water.

Thus, in the state in which the antibacterial silicone hose 54 is inserted into a user's bowels through his or her anus, the bowels are washed. Further, in the state where the antibacterial silicone hose 54 is inserted into a user's vagina, the interior of the vagina is washed.

[38] Referring to FIGS. 1 and 2, the bidet according to the present invention is provided with a control valve 60 which controls the supply of the washing water discharged from the outlet 24b of the filter chamber 24 of the filter 20, thus supplying the washing water to either the shower nozzle 40 or the bidet nozzle 50.

[39] As shown in FIG. 3, the control valve 60 includes a lid 62 having a water inlet passage 62a, a body 64 having on the circumference thereof first and second water outlet passages 64a and 64b which communicate with the water inlet passage 62a, a rotary adjusting disc 65, and a manipulating knob 66. The rotary adjusting disc 65 is rotatably installed between the lid 62 and the body 64, and has a communication hole 65a through which the water inlet passage 62a communicates with the first water outlet passage 64a, or through which the water inlet passage 62a communicates with the second water outlet passage 64b, according to the rotational position of the rotary adjusting disc 65. The manipulating knob 66 is mounted on the lid 62 to allow a user to rotate the rotary adjusting disc 65.

[40] Here, a distribution disc 67 having through holes 67a which correspond to the first and second water outlet passages 64a and 64b is located above the first and second water outlet passages 64a and 64b of the body 64. A packing 68 is provided between the distribution disc 67 and the body 64. Further, the rotary adjusting disc 65 and the manipulating knob 66 are coupled to each other via a coupling shaft 66a. The rotary adjusting disc 65 is elastically biased downwards by a spring 68 so that the rotary adjusting disc 65 is kept in close contact with the distribution disc 67.

[41] In such a control valve 60, the water inlet passage 62a is connected to the outlet 24b of the filter chamber 24 of the filter 20, the first water outlet passage 64a is connected to the shower nozzle 40, and the second water outlet passage 64b is connected to the bidet nozzle 50. Thus, when a user rotates the rotary adjusting disc 65 using the manipulating knob 66 so that the water inlet passage 62a communicates with the first water outlet passage 64a, washing water flowing into the water inlet passage 62a is fed to the first water outlet passage 64a, and the washing water fed into the first water outlet passage 64a is supplied to the shower nozzle 40. Conversely, when a user rotates the rotary adjusting disc 65 using the manipulating knob 66 so that the water inlet passage 62a communicates with the second water outlet passage 64b, washing water flowing into the water inlet passage 62a is fed to the second water outlet passage 64b, and the washing water fed into the second water outlet passage 64b is supplied to the bidet nozzle 50.

[42] Consequently, the control valve 60 functions to supply washing water, discharged from the outlet 24b of the filter chamber 24, to either the shower nozzle 40 or the bidet nozzle 50, according to the user's manipulation. In this case, the rotary angle of the rotary adjusting disc 65 is finely adjusted by the control valve 60 to control the communication of the communication hole 65a of the rotary adjusting disc 65 with the first or second water outlet passage 64a or 64b, thus controlling the pressure or amount of washing water. Although the control valve 60 mounted to the head 30 is shown in the drawing, the control valve 60 may be mounted to the filter 20.

[43] Meanwhile, the drawing of the present invention shows the body 64 of the control valve 60, which further includes third and fourth water outlet passages 64c and 64d. The third and fourth water outlet passages 64c and 64d are spare water outlet passages which are used when a plurality of bidet nozzles 50 is mounted to the head 30. Of course, a plurality of water outlet passages may be formed, if necessary.

[44] FIG. 4 shows a modification of a control valve 70. According to the modification, the control valve 70 includes a rectangular box-shaped body 72, a spool 74, a manipulating knob 75, and a lid 76. The rectangular box-shaped body 72 has first and second water outlet passages 72a and 72b. The spool 74 is mounted to the upper surface of the body 72 in such a way as to move rectilinearly, and has a water inlet passage 74a which selectively communicates with the first water outlet passage 72a or the second water outlet passage 72b, according to the position of the spool. The manipulating knob 75 is installed to allow a user to manipulate the spool 74. The lid 76 covers the body 72, the spool 74, and the manipulating knob 75.

[45] In this case, a distribution plate 77, having through holes 77a which correspond to the first and second water outlet passages 72b, is located above the first and second water outlet passages 72b of the body 72. A packing 78 is provided between the distribution plate 77 and the body 72. Further, a protrusion 75a of the manipulating knob 75 protrudes upwards from the lid 76, with an adjusting handle 75b mounted to an end of the protrusion 75a. Further, the spool 74 is elastically biased downwards by springs 79, so that the spool 74 is in close contact with the distribution plate 77.

[46] In the control valve 70, the water inlet passage 74a is connected to the outlet 24b of the filter chamber 24 of the filter 20, the first water outlet passage 72a is connected to the shower nozzle 40, and the second water outlet passage 72b is connected to the bidet nozzle 50. Thus, when a user rectilinearly moves the spool 74 using the manipulating knob 75 to make the water inlet passage 74a communicate with the first water outlet passage 72a, washing water introduced into the water inlet passage 74a is supplied to the first water outlet passage 72a, and washing water supplied to the first waster outlet passage 72a is supplied to the shower nozzle 40. Conversely, when he or she rectilinearly moves the spool 74 using the manipulating knob 75 to make the water inlet passage 74a communicate with the second water outlet passage 72b, washing water introduced into the water inlet passage 74a is supplied to the second water outlet passage 72b, and washing water supplied to the second water outlet passage 72b is supplied to the bidet nozzle 50.

[47] Consequently, the control valve 70 functions to supply washing water, discharged from the outlet 24b of the filter chamber 24, to either the shower nozzle 40 or the bidet nozzle 50, according to the user's manipulation.

[48] Meanwhile, FIG. 4 shows the control valve 70 which further has on the body 72 thereof a third water outlet passage 72c. The third water outlet passage is a spare water outlet passage which is used when a plurality of bidet nozzles 50 is mounted to the head 30. Of course, a plurality of water outlet passages may be formed if necessary.

[49] The operation of the bidet according to the present invention, which is constructed as described above, will be described with reference to FIGS. 1 and 2. First, after the inlet hose 10 is coupled to the water pipe, the water pipe is opened. At this time, water is introduced from the water pipe to the inlet hose 10. The introduced water flows into the filter chamber 24 of the filter housing 22. The inflow water is purified while passing through the filtering elements in the filter chamber 24, that is, the activated carbon.

[50] Meanwhile, the purified washing water is discharged through the outlet 24b, and the discharged washing water flows through a discharge tube 60a to the control valve 60. In this case, when the control valve 60 makes the discharge tube 60a communicate with the first coupling tube 46, washing water is supplied from the discharge tube 60a to the shower nozzle 40. The supplied washing water is sprayed outside through the nozzle plate 44. Thus, a user can take a shower using the washing water.

[51] Further, when a user manipulates the control valve 60 so that the discharge tube 60a communicates with the second coupling tube 55, the washing water of the discharge tube 60a is supplied to the bidet nozzle 50. The supplied washing water flows into the inner body 52a of the nozzle body 52. The inflowing washing water flows into the passage 54a in the antibacterial silicone hose 54, and is sprayed through the nozzle head 54c.

[52] At this time, the washing water sprayed forwards maintains its high pressure, thus moving the antibacterial silicone hose 54 forwards. Thus, the antibacterial silicone hose 54 protrudes forwards, and is inserted into a user's bowels or vagina, thus washing his or her bowels or vagina.

[53] FIG. 5 is a view showing the modification of a filter 20 and a head 30 included in the bidet, according to the present invention. As shown in the drawing, the filter 20 and the head 30 according to the modification communicate with each other, thus forming one filter chamber 24. Of course, the filtering elements and the post-processing filter 28 are installed in the filter chamber 24. In this case, the post-processing filter 28 is mounted to the upper portion of the filter chamber 24.

[54] When the filter 20 and the head 30 are constructed as described above, the control valve 60 is installed in the filter chamber 24. In this case, the control valve 60 is coupled to the discharge tube 60a for discharging washing water from the postprocessing filter 28. Thus, washing water discharged from the post-processing filter 28 is introduced into the control valve 60. Further, the control valve 60 has a first coupling tube 46 and a second coupling tube 55 for discharging washing water. The first coupling tube 46 and the second coupling tube 55 supply washing water, the flow direction of which is controlled by the control valve 60.

[55] Meanwhile, ends of the first and second coupling tubes 46 and 55 are exposed outside the head 30. Connectors 46a and 55a are mounted to the exposed ends of the first and second coupling tubes 46 and 55, respectively. The shower nozzle 40 and the bidet nozzle 50 are connected to the connectors 46a and 55a, respectively.

[96] The bidet nozzle 400 of the third modification generates waves in washing water using the vibrations of the vibration unit 422, thus maximally increasing the washing effect. Further, as necessary, after the vibration insert unit 430 is separated, washing water is sprayed through the nozzle cap 470, thus simply washing a user's bowels.

[97] FIG. 17 shows a bidet nozzle 500 according to the fourth modification. The bidet nozzle 500 of the fourth modification is a telescopic-type nozzle, and has a nozzle body 510 and a telescopic movable pipe 520 which is movably disposed in the nozzle body 510. Especially, the telescopic movable pipe 520 protrudes from an open rear portion 510a of the nozzle body 510, and moves forwards into the nozzle body 510, thus overlapping the nozzle body 510.

[98] In this case, a protruding part 522 is provided on the circumference of the front portion of the telescopic movable pipe 520, and a locking step 512 is provided on the rear portion of the inner circumference of the nozzle body 510 such that the protruding part 522 of the telescopic movable pipe 520 is locked to the locking step 512. Thus, the telescopic movable pipe 520 is constructed so that the protruding part 522 is locked to the locking step 512 of the nozzle body 510, so that the telescopic movable pipe 520 does not become detached in a backward direction.

[99] The bidet nozzle 500 of the fourth modification is provided with an antibacterial silicone hose 530 which is accommodated in the nozzle body 510 and the telescopic movable pipe 520. The antibacterial silicone hose 530 is extended from the nozzle body 510 and is inserted into a user s bowels or vagina, with a water outlet cap 532 fitted over the antibacterial silicone hose. The water outlet cap 532 is fastened to an open front portion 510b of the nozzle body 510 through a screw-type fastening method, so that the front portion of the antibacterial silicone hose 530 is supported by the nozzle body 510.

[100] Further, a coupling member 534 is coupled to the rear portion of the antibacterial silicone hose 530, and a locking member 535 is fastened to the coupling member 534. The locking member 535 fastened to the coupling member 534 is locked to the water outlet cap 532, thus limiting the forward movement of the antibacterial silicone hose 530, therefore preventing the removal of the antibacterial silicone hose 530.

[101] Meanwhile, the rear end of the antibacterial silicone hose 530 is integrally secured to the rear portion of the telescopic movable pipe 520. Thus, when the telescopic movable pipe 520 moves forwards relative to the nozzle body 510 and overlaps the nozzle body 510, the antibacterial silicone hose 530 secured to the telescopic movable pipe moves forwards and protrudes forwards from the nozzle body 510, thus inserting itself into a user's bowels or vagina.

[102] In this case, the rear end of the antibacterial silicone hose 530 is secured by a fastening member 537 which is fastened to the rear surface of the telescopic movable pipe 520. The fastening member 537 and the telescopic movable pipe 520 are coupled to each other via coupling rings 537a. Further, the length of the antibacterial silicone hose 530 is longer than the length thereof when the telescopic movable pipe 520 and the nozzle body 510 are extended.

[103] The bidet nozzle 500 of the fourth modification further includes a spring 540 which is fitted over the antibacterial silicone hose 530. The lower end of the spring 540 is supported by a support step 535a of the locking member 535, thus elastically biasing the antibacterial silicone hose 530 in the direction of insertion of the antibacterial silicone hose into the nozzle body 510. Thus, the antibacterial silicone hose 530 is returned to the interior of the nozzle body 510. The telescopic movable pipe 520 integrally secured to the antibacterial silicone hose 530 moves rearwards from the nozzle body 510 along with the antibacterial silicone hose 530, thus being extended from the nozzle body 510.

[104] According to this modification, the spring 540 is mounted only to the circumference of the antibacterial silicone hose 530, and the antibacterial silicone hose 530 is elastically biased into the nozzle body 510 by the spring. However, as necessary, an additional spring may be installed to elastically compress the telescopic movable pipe 520, thus compressing the telescopic movable pipe 520 and the antibacterial silicone hose 530 toward the rear of the nozzle body 510.

[105] As necessary, the bidet nozzle 500 of the fourth modification further has a nozzle cap 550 which is fastened to the front of the nozzle body 510 through a screw-type fastening method to cover the nozzle head 530a of the antibacterial silicone hose 530. The nozzle cap 550 is provided with a through hole 550a. Since the nozzle head 530a of the antibacterial silicone hose 530 protrudes through the through hole 550a, it may serve as a bidet.

[106] The bidet nozzle 500 of the fourth modification is operated as follows. When washing water flows into the nozzle body 510, the washing water is introduced into the antibacterial silicone hose 530. The antibacterial silicone hose 530 is moved forwards by the pressure of the tap water and is inserted into the bowels or vagina, so that the inserted antibacterial silicone hose 530 sprays washing water through the nozzle head 530a, thus washing the interior of the bowels or vagina.

[107] Meanwhile, as the antibacterial silicone hose 530 is extended forwards, the telescopic movable pipe 520 coupled to the antibacterial silicone hose moves forwards and overlaps the nozzle body 510. Thus, the entire length of the bidet nozzle 500 is reduced, so that it is very convenient to use.

[108] The bidet nozzle 500 of the fourth modification is characterized in that the nozzle body 510 has a multi-stage structure and is telescopic, so that it is very convenient to use. Especially, when a user sits and uses the bidet nozzle, the overall length of the bidet nozzle 500 is reduced, so that it is convenient to use without interference from the floor.

[109] FIG. 18 shows a bidet nozzle 600 according to the fifth modification. The bidet nozzle of the fifth modification has a telescopic construction, like the bidet nozzle of the fourth modification. However, the bidet nozzle of the fourth modification has a two-staged shape, whereas the bidet nozzle of the fifth modification has a three-staged shape. That is, the bidet nozzle 600 of the fifth modification has one nozzle body 610 and two telescopic movable pipes, that is, first and second telescopic movable pipes 620 and 622. The general construction of the bidet nozzle of the fifth modification remains the same as that of the fourth modification.

[110] The bidet nozzle 600 of the fifth modification is advantageous in that it has a three- staged structure, so that the overall length of the bidet nozzle 600 can be further reduced, and is thereby very convenient to use.

Especially, when the antibacterial silicone hose 720 passes through a through hole 732 of the nozzle cap 730 and extends a long distance forwards from the nozzle cap, the rear end of the antibacterial silicone hose 720 is firmly supported by the nozzle cap 730.

[112] In this case, a locking member 722 is fitted over the lower end of the antibacterial silicone hose 720, and a locking ring 724 is fitted over the locking member 722. While the locking member 724 is secured to the lower end of the antibacterial silicone hose 720, the locking member is locked to the inner circumference of the nozzle cap 730. Thereby, the antibacterial silicone hose 720 is fitted into the through hole 732 of the nozzle cap 730 and does not become detached in a forward direction.

[113] Meanwhile, a support member 740 is fastened to the open rear end of the nozzle cap

730 through a screw-type fastening method, thus pressing and supporting the rear end of the antibacterial silicone hose 720. The support member 740 presses and supports the rear end of the antibacterial silicone hose 720, so that the antibacterial silicone hose 720 is not removed from the open rear end of the nozzle cap 730.

[114] In the bidet nozzle 700 of the sixth modification, the antibacterial silicone hose 720 extends a long distance forwards. In such a state, the antibacterial silicone hose is secured to the nozzle cap 730, so that it is very convenient to insert the extended antibacterial silicone hose 720 into the bowels or vagina. Thus, it is very convenient to use.

[115] FIG. 20 shows the state in which the bidet nozzle 700 of the sixth modification is mounted to the head 30. Referring to the drawing, the bidet nozzle 700 of the sixth modification is mounted to the open front of the head 30.
