(Embodiment 1)
FIG. 1 shows a perspective view of a toilet apparatus according to Embodiment 1 of the present invention. FIG. 2 is a perspective view of a connecting portion of the toilet apparatus shown in FIG. 3 is a cross-sectional view taken along line AA of the connecting portion shown in FIG.

  As shown in FIG. 1, the toilet device includes a cleaning device main body (hereinafter referred to as a main body) 1, a cleaning unit 3, a water supply pipe 5, and a connecting pipe 7. The main body 1 is provided horizontally on the toilet bowl 2. The cleaning unit 3 is used for cleaning a local part of a human body with warm water or room temperature water. The water supply pipe 5 connects the water supply pipe 4 and the water supply section 9 provided on the main body 1 side with a pipe plug 8 and supplies water used for cleaning from the water supply pipe 4 to the cleaning section 3. The connecting pipe 7 joins the end of the water supply pipe 5 and the water supply part 9 in a watertight manner. The water supply unit 9 has an opening 9 c for introducing tap water supplied from the water supply pipe 5. And the water supply part 9 is connected to the washing | cleaning part 3 via the main body water channel part (henceforth a water channel) 6. The connecting pipe 7 is a piping plug that hermetically seals the opening 9c. The main body 1 further includes a toilet seat 13 and a toilet lid 14.

  As shown in FIG. 2, the piping plug body portion of the toilet apparatus includes a water supply unit 9 and a connecting pipe 7 that is screwed to the water supply unit 9.

  And as shown in FIG. 3, the connection pipe 7 has the inner member 11 and the outer member 12 which are located inside and outside the opening end part 9b of the water supply part 9. As shown in FIG. The inner member 11 and the outer member 12 are composed of separate parts. And the nail | claw part 15 provided in the inner member 11 and the hole part 16 provided in the outer member 12 are fitted together, and the inner member 11 and the outer member 12 are assembled and combined so that it can move to an axial direction. Yes.

  Screws are formed on the opposing portions of the inner member 11, the outer member 12, and the water supply tube (hereinafter referred to as a tube) 9 a of the water supply unit 9. Therefore, the connecting pipe 7 and the water supply part 9 are joined by double screw connection. In order to prevent freezing, the connecting pipe 7 also has a function as a drain plug for draining water from the water channel 6 and the water supply pipe 5. Unevenness is formed on the outer surface of the outer member 12, and a grip 29 is provided.

  The water supply unit 9 has a first female screw (hereinafter referred to as a screw) 17 on the inner surface side of the tube body 9a. A second male screw (hereinafter referred to as a screw) 18 is provided on the outer surface side of the tube body 9a.

  Further, the inner member 11 has a first male screw (hereinafter referred to as a screw) 20 and a first sealing material (hereinafter referred to as a sealing material) 23 that are screw-coupled to the screw 17. The external member 12 has a second female screw (hereinafter referred to as a screw) 19 that is screw-coupled with the male screw 18. The screw 20 and the screw 17 constitute a first screw pair (hereinafter referred to as a screw pair) 21, and the screw 18 and the screw 19 constitute a second screw pair (hereinafter referred to as a screw pair) 22. Is configured. Since the first and second screw pairs 21 and 22 are screwed at the same time, the reliability of the connection between the water supply pipe 5 and the water supply unit 9 is enhanced. Further, the inner member 11 and the outer member 12 are joined so as to be movable in the axial direction, so that one of the two screw pairs 21 and 22 is delayed after the other screw pair is screwed. Can be screwed together.

  The water supply pipe 5 is provided with a water supply pipe joint (hereinafter referred to as a joint) 30. The water supply pipe 5 and the connecting pipe 7 are connected by sandwiching the joint 30 between the inner member 11 and the outer member 12 and fitting the claw 15 and the hole 16 together. Thus, the water supply pipe 5 and the connecting pipe 7 are joined by a very simple configuration and method.

  Further, a second sealing material (hereinafter referred to as a sealing material) 24 is provided on the outer periphery of the joint 30. Further, the joint 30 is provided with joint protrusions (hereinafter referred to as protrusions) 30 a and 30 b that hold the sealing material 24 and hold the water supply pipe 5 so as not to be pulled out from the connecting pipe 7. .

  When the inner member 11 and the outer member 12 are coupled, the joint 30 having the protrusions 30 a and 30 b is sandwiched between the inner member 11 and the outer member 12. When a pulling force is applied to the water supply pipe 5 in the direction of pulling out from the connecting pipe 7, the protrusion 30 a hits the outer member 12 and prevents the water supply pipe 5 from being pulled out. Further, when a pushing force is applied to the water supply pipe 5 in the direction of pushing into the connecting pipe 7, the protruding portion 30 b hits the inner member 11 and prevents the water supply pipe 5 from being pushed in.

  The sealing materials 23 and 24 are O-rings or packing made of acrylonitrile butadiene rubber (NBR), ethylene propylene rubber (EPDM), styrene butadiene rubber (SBR), or the like. The sealing material 23 seals a gap formed between the inner surface of the water supply unit 9 and the outer surface of the inner member 11 in a water-tight manner, and prevents water from leaking from the gap. With respect to the connection between the connecting pipe 7 and the water supply unit 9, tap water inside the water supply unit 9 is applied in a direction in which the connecting pipe 7 is detached. However, since the connection force between the connecting pipe 7 and the water supply unit 9 is obtained by the double screw connection of the screw pairs 21 and 22, the connection is not disconnected. Further, a sealing structure of the connecting pipe 7 and the water supply unit 9 is obtained by the sealing material 23. And the joining force which opposes a tap water pressure is obtained with the screw pairs 21 and 22.

  Moreover, the sealing material 24 seals a gap formed between the inner surface of the inner member 11 and the outer surface of the joint 30 in a watertight manner, and prevents water from leaking from the gap. With respect to the connection between the connecting pipe 7 and the water supply pipe 5, tap water pressure is applied between the inside of the water supply pipe 5 and the inside of the water supply section 9 in the direction in which the water supply pipe 5 is detached. However, the protrusion 30a does not hit the outer member 12, and the connecting pipe 5 does not come off. Further, a sealing structure of the connecting pipe 7 and the water supply pipe 5 is obtained by the sealing material 24.

  Furthermore, the connection structure between the connecting pipe 7 and the water supply pipe 5 is such that the sealing material 24 and the inner surface of the inner member 11 are slidably held. Thereby, the connecting pipe 7 and the water supply pipe 5 are not restrained with respect to the rotation direction. And when rotating the outer member 12 and connecting the connection pipe 7 and the water supply part 9, it slides between the inner member 11 and the water supply pipe 5, and the water supply pipe 5 is joined without rotating. Since the water supply pipe 5 does not rotate, the water supply pipe 5 is not kinked or broken. Therefore, a highly reliable connecting pipe 7 with good workability is realized.

  Furthermore, the screws 17, 18, 19, 20 constituting the screw pair 21, 22 have substantially the same screw pitch.

  As shown in FIG. 3, the moving distance “a” between the inner member 11 and the outer member 12 in the axial direction is not less than one pitch and not more than two pitches of the screws 17, 18, 19, and 20. As a result, it is not necessary to align the positions at which the threads of the screws 17, 18, 19, and 20 start to be cut. That is, when joining the connecting pipe 7 to the water supply unit 9, the connecting pipe 7 moves within the range of movement from the 1st pitch to the 2nd pitch axis while the rotation angle of the connecting pipe 7 is rotated from the minimum 0 ° to the maximum 360 °. . Thereby, the screw connection of the screw pairs 21 and 22 is easily performed.

  About the toilet apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, the water supply original pressure from the water supply pipe 4 is applied to the water supply part 9 through the water supply pipe 5 and acts as a force for pulling out the connecting pipe 7 from the open end 9b. Since there is a double screw coupling force due to the screw coupling of the screw pair 21 and the screw coupling of the screw pair 22, the connecting pipe 7 is held in combination with the water supply unit 9 without being pulled out.

  In the manufacturing process of the connecting pipe 7, if an imperfect defect such as a small number of threads of the screws 17, 18, 19, 20 occurs, the threads may be damaged. Furthermore, the thread may be deteriorated and damaged due to the influence of aged water pressure fluctuation. Since the screw connection is doubled, even if only one of the screw connections is incomplete, the connection pipe 7 and the water supply unit 9 continue to be connected as long as the other screw connection is sufficient. . And the connection of the connection pipe 7 and the water supply part 9 does not become incomplete, and a water leak etc. do not generate | occur | produce.

  Furthermore, even if an abnormally high water pressure is applied to the connecting portion between the connecting portion 7 and the water supply portion 9 due to the water hammer phenomenon of the water supply source pressure, the connecting tube 7 does not easily come off.

  The connecting pipe 7 is composed of two parts, an inner member 11 and an outer member 12. Thus, the screws 17, 18, 19, and 20 may be formed separately on the inner member 11 and the outer member 12 by molding. For this reason, the mold structure when the inner member 11 and the outer member 12 are molded is simplified, the processing is easy, and the component cost is reduced.

  Further, a guide 25 having no thread is provided at the screw start position of the screw 18 at the tip of the water supply unit 9. The outer diameter of the guide 25 is set smaller than the outer diameter of the screw thread of the screw 18. The guide 25 guides the tube body 9a into the outer member 12 before the screw pairs 21 and 22 start to engage with each other. Thereby, the screw pairs 21 and 22 are smoothly screw-coupled without tilting and start to engage with each other.

  Further, a hook-like or flange-like protrusion 27 is provided at the end position portion of the screw 18. When the screw connection of the screw pair 22 is sufficiently fastened, the dome-shaped lid protrusion 28 provided on the outer member 12 hits the protrusion 27. Then, it is noticed that the screw connection is completely performed with a sharp feeling.

  Moreover, since the outer peripheral part of the connection pipe 7 has the screw 20 inside, the length more than the effective length of a screw is required for an axial direction. For this reason, the grip 29 has a size that can be grasped not only by the fingertip but also by the whole finger or the palm, and the connection pipe 7 and the water supply section 9 can be easily connected. Furthermore, since the grip 29 is provided, the connecting pipe 7 can be firmly gripped when being attached to and detached from the water supply unit 9 and can be easily rotated. Therefore, it is easy to rotate the connecting pipe 7 and tighten it sufficiently to the end, and the screw coupling portion is satisfactorily performed and prevented from being used in a short state.

  Thus, since the water supply part 9 and the connection pipe 7 are couple | bonded by the double screw coupling | bonding of the screw pairs 21 and 22, coupling reliability is high. Moreover, even if an abnormally high water pressure is applied in the case of a halfway screw connection due to defective parts or insufficient fastening work, the screw connection will not be released. As a result, there is less water leakage and a highly reliable toilet device is provided.

  In addition, in the path | route which supplies water from the water supply pipe 4 to the main body 1, only one connection part which connects the water supply pipe 5 and the water supply part 9 is enough. Therefore, even when a general user pipes the toilet device or removes the joint portion by maintenance work, the work can be performed easily and reliably. Moreover, since the inspection confirmation of the junction part in a manufacturing process, etc. may be one place, manufacturing cost is suppressed.

  The moving distance a was set to be not less than 1 pitch and not more than 2 pitches of the screw pitch of the screw pair 21 or 22. However, it is not necessarily limited to this range. The lower limit value of the moving distance a is a deviation distance that is a product of a deviation angle between a screw engagement start position of the screw pair 21 and a screw engagement engagement position of the screw pair 22 and a screw pitch. By setting the moving distance a to be equal to or greater than the deviation distance, the screw pair 21 and the screw pair 22 are smoothly screw-coupled. Furthermore, the upper limit value of the movement distance a is not particularly limited. However, when the moving distance a is too large, the number of rotations of the connecting pipe 7 until both the screw pairs 21 and 22 are engaged becomes too large, which is inefficient. Therefore, when the upper limit value of the moving distance a is equal to or less than two pitches of the screw pitch, after one of the screw pairs 21 and 22 is engaged, the rotation angle of the connecting pipe 7 is 360 ° or less and the other is rotated. The conditions for meshing are established. Therefore, when the moving distance a is not less than one pitch and not more than two pitches of the screw pair 21 or 22, the screw pair 21 and the screw pair 22 are smoothly and efficiently screw-coupled. Is done.

  The connecting pipe 7 has a structure in which separate components of the inner member 11 and the outer member 12 are combined. However, as shown in FIG. 4, the connecting pipe 7a is a double-piece connecting pipe 7a having an inner member 11a and an outer member 12a, and a joint protrusion (hereinafter referred to as a protrusion) 30c is provided in the water supply pipe 5. It is good also as the structure made. In this case, since the inner member 11a and the outer member 12a constituting the connecting pipe 7a are formed of a single part, the parts can be easily managed and the manufacturing management cost can be reduced. Further, when a pushing force is applied to the water supply pipe 5 in the direction of pushing into the connecting pipe 7, the protrusion 30 c hits the connecting pipe 7 a and prevents the water supply pipe 5 from being pushed in.

  Further, the outer surface of the outer member 12 has a structure in which irregularities are formed and a grip 29 is provided. However, as shown in FIG. 5, the outer surface of the outer member 12b may be a connecting pipe 7b having a smooth outer surface with no irregularities. In this case, the surface of the connecting pipe 7b becomes slippery, but since the processing of the connecting pipe 7b becomes easy, the manufacturing cost is reduced.

  In addition, although the main body 1 demonstrated the structure which has the toilet seat 24 and the toilet lid 25, the toilet seat 24 and the toilet lid 25 are not necessarily required. If the toilet seat 24 is provided, the effect that the user of a toilet device can use a toilet device cleanly will be acquired. Moreover, when the toilet lid 25 is provided, the bad smell in the toilet bowl 2 is contained, and a clean environment without an odor is realized in a toilet space (not shown) provided with a toilet device.

(Embodiment 2)
FIG. 6 shows a perspective view of a piping plug part of a toilet apparatus according to Embodiment 2 of the present invention. 7 is a cross-sectional view taken along the line B-B of the piping plug part shown in FIG. 6. FIG. 8 is a perspective view of the piping plug body shown in FIG.

  In the toilet apparatus according to the second embodiment, the same components as those of the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 6, the water supply unit 9 has an L-shaped water channel 40, and supplies water from the rear side of the main body 1 downward (in the range indicated by the arrow C in FIG. 6) via a connecting pipe 7 c that is a plug for piping. The pipe 5 is joined to the water supply unit 9.

  Further, as shown in FIG. 7, a filter 41 is provided inside the connecting pipe 7c. And the filter part 41 is hold | maintained so that attachment or detachment is possible from the connection pipe 7c (not shown).

  By having the L-shaped water channel 40, the attachment direction of the water supply pipe 5 can be freely selected from the rear to the bottom of the main body 1. Thereby, the freedom degree of arrangement | positioning of water supply piping, such as the water supply pipe 5 or the water supply pipe 4, increases in the narrow toilet space. The toilet space can be used efficiently, and the water supply pipe can be installed at a position that does not get in the way.

  Further, since the connecting portion between the connecting pipe 7c and the water supply unit 9 has a double screw connection, dimensions for forming the screws 17, 18, 19, and 20 are required. For this reason, the grip 29 becomes long in the axial direction, and the projecting dimension from the main body 1 is large. And it looks bad.

  Further, in the structure in which the water supply pipe 5 is connected from the side surface of the main body 1, the water supply pipe is often disturbed inside the narrow toilet space. However, since the attachment direction of the water supply pipe 5 can be freely selected from the rear to the lower side of the main body 1, the interior of the toilet space can be effectively used. As a result, the water supply pipe does not get in the way. This is a significant effect in a narrow toilet space.

  Further, the cleaning tap water supplied to the cleaning unit 3 contains dust or foreign matter. By filtering such dust or foreign matter with the filter 41, cleaner cleaning using water that does not contain dust or foreign matter is possible. As a result, the user of the toilet device is not uncomfortable.

  In addition, entry of dust, foreign matter and the like into the cleaning unit 3 inside the water channel 6 is prevented, and failure of a plurality of valve units (not shown) provided in the water circuit inside the main body 1 is prevented. Can be removed.

  Moreover, as shown in FIG. 8, the joint of the connecting pipe 7c and the water supply part 9 is removed, and the filter 41 can be cleaned. For this reason, the maintenance of the filter 41 is easy.

  Furthermore, since the filter 41 is detachably held from the connecting pipe 7c, the filter 41 can be removed from the connecting pipe 7c and cleaned, and maintenance is high. For example, even if the filter 41 is not removable from the connecting pipe 7c, the filter 41 can be cleaned in the toilet space. However, a cleaning facility for cleaning the filter 41 is required in the toilet space. Since the connecting pipe 7c is a structure coupled to the water supply pipe 5 branched from the water pipe 4, it is difficult to move the filter 41 to the outside of the toilet space.

  However, since the filter 41 is detachably held from the connecting pipe 7c, it is possible to separate only the filter 41 from the connecting pipe 7c and clean the filter 41 in another place outside the toilet space. . Furthermore, after cleaning the filter 41, the filter 41 is mounted again on the connecting pipe 7c. And since the connecting pipe 7c and the water supply pipe 5 are connected by double screw coupling, a toilet apparatus with extremely high maintainability is realized.

  Although the filter 41 is detachably held on the connecting pipe 7c, it is not always necessary to be detachable. For example, when the connecting pipe 7c and the water supply pipe 5 are configured to be detachable, the filter 41 can be taken out of the toilet space while being attached to the connecting pipe 7c.

(Embodiment 3)
FIG. 9 shows a perspective view of a piping plug part of a toilet apparatus according to Embodiment 3 of the present invention. FIGS. 10-16 shows sectional drawing of the plug body part for piping shown in FIG. FIG. 17 is a front view of the piping plug body shown in FIG. 9.

  In the toilet apparatus in the third embodiment, the same components as those in the first and second embodiments are denoted by the same reference numerals, and detailed description thereof is omitted.

  In the third embodiment, the piping plug body is used as a drain plug 45 for draining water from the piping to prevent freezing.

  As shown in FIG. 10, the drain plug 45 is joined to the water supply unit 9 in a watertight manner so as to seal the opening 9 c provided in the water supply unit 9 in order to drain water from the water supply unit 9. The drain plug 45 includes a drain plug inner member (hereinafter referred to as “inner member”) 46 and a drain plug outer member (hereinafter referred to as “outer member”) 47 located inside and outside the opening end 9 b of the water supply section 9. And have. Since the coupling structure between the inner member 46 and the outer member 47 is the same as the coupling structure between the inner member 11 and the outer member 12 described above, detailed description thereof is omitted.

  Further, the drain plug 45 and the water supply unit 9 are joined by a double screw connection by the first screw pair 21 and the second screw pair 22.

  Further, as shown in FIG. 11, the engagement start position of the screw connection between the water supply unit 9 and the drain plug 45 is the same as the screw connection of the first screw pair 21 and the screw connection of the second screw pair 22. It starts with Then, since the engagement of the two screws starts at the same time, there is no sense of incongruity in the feeling of screw connection. Further, since the screw connection is doubled, the reliability of the screw connection portion is improved.

  Further, as shown in FIG. 15, the engagement start position of the screw connection between the water supply portion 9 and the drain plug 45 is such that the screw connection of the first screw pair 21 is ahead of the screw connection of the second screw pair 22. May be done. In this case, even if the engagement start position of the screw connection of the two screw pairs 21 and 22, that is, the screw thread start positions of the respective screws 17, 18, 19 and 20 are not exactly the same, double screw connection is formed. Is done. Moreover, even if there is no screw connection of the second screw pair 22, the drain plug 45 is not detached from the water supply section 9, and water leakage is prevented. In this case, the shift amount of the position where the screw coupling between the screw pair 21 and the screw pair 22 starts to be engaged is set smaller than the axial movement distance a between the inner member 46 and the outer member 47.

  On the contrary, as shown in FIG. 16, the screw coupling of the second screw pair 22 is the screw coupling of the first screw pair 21 at the position where the screw coupling of the water supply unit 9 and the drain plug 45 starts.

  Furthermore, the assembly of the inner member 46 and the outer member 47 will be described with reference to FIGS. 13 and 14.

  A plurality of claw portions 15 are provided on the end surface of the inner member 46. Further, the outer member 47 is provided with a hole 16 for engaging the pawl 15. The inner member 46 is pressed toward the outer member 47, and the inner member 46 is assembled with the outer member 47 (in the direction of arrow F in FIG. 13). At this time, the pawl 15 is elastically deformed and inserted into the hole 16. After the insertion of the pawl 15, the engagement portion 15 a at the tip of the pawl 15 is engaged with the hole 16 by restoring the deformation of the pawl 15. Thus, the inner member 46 and the outer member 47 are coupled and assembled with a simple configuration. The inner member 46 and the outer member 47 are movable in the axial direction, but the engaging portion 15a is not engaged with the hole portion 16 and detached. Further, at the time of rotation for screw connection between the water supply portion 9 and the drain plug 45, the pawl portion 15 is caught by the hole portion 16, and the inner member 46 also rotates as the outer member 47 rotates. This facilitates the screw connection of the screw pairs 21 and 22.

  Further, as shown in FIGS. 9 and 17, two ribs 26 for improving the strength are provided inside the inner member 46. The ribs 26 increase the mechanical strength of the inner member 46. Further, when the screw connection between the water supply unit 9 and the drain plug 45 is firmly connected, when the screw connection is difficult to be removed, a tool or a coin is inserted into the rib 26 to give the drain plug 45 a rotational force. Can do. As a result, the screw connection between the water supply unit 9 and the drain plug 45 is easily released. Even if the rib 26 is provided on the outer member 47 side, the same effect can be obtained.
