The devices described in both patent documents have a function of cleaning the cleaning nozzle itself in order to ensure the hygiene of the cleaning nozzle.

JP 2004-100370 A JP 2002-364055 A

  The apparatus described in Patent Document 1 has a configuration in which a means having a nozzle cleaning function is simply added separately, and thus causes problems such as an increase in the number of parts and an increase in part arrangement space. Since the apparatus described in Patent Document 2 is designed to eject cleaning water from a cleaning nozzle and reflect it with a shutter to clean the nozzle itself (see FIG. 7 of Patent Document 2), the cleaning effect is low. . In particular, there is almost no cleaning effect on the nozzle front and back surfaces.

  The problem to be solved by the present invention is to provide a local cleaning device having a nozzle cleaning function that exhibits an excellent cleaning effect on the cleaning nozzle without causing an increase in the number of components and an increase in the component arrangement space. is there.

  In order to solve the above-mentioned problems, a local cleaning apparatus according to the present invention includes a cleaning nozzle that moves forward and backward through an opening, covers the opening when the cleaning nozzle is in the original position, and the cleaning nozzle advances from the original position. A shutter that opens the opening at the time, and a surface of the shutter on the side of the cleaning nozzle is provided with an ejection port from which liquid is ejected.

  The spout should just be provided in the location which overlaps with the tip face of the washing nozzle located in the original position in the advancing and retreating direction of the washing nozzle.

  The said jet nozzle should just be provided below the said washing nozzle located in the original position.

  The spout provided below the cleaning nozzle may have a shape inclined toward the cleaning nozzle.

  The shutter may have a lower surface facing portion that faces the lower surface of the cleaning nozzle, and the ejection port may be provided in the lower surface facing portion.

  The shutter in a state where the opening is opened may be located above the cleaning nozzle.

  The local cleaning apparatus according to the present invention is provided with an ejection port for ejecting a liquid (a cleaning liquid for cleaning the cleaning nozzle) to a shutter that covers a tip portion of the cleaning nozzle. That is, since the cleaning liquid is directly sprayed onto the cleaning nozzle, the cleaning effect is high. In addition, since the cleaning function is added to the shutter that covers the cleaning nozzle, the number of parts and the arrangement space are not increased.

  If the spout is provided at a position overlapping the front end surface of the cleaning nozzle located in the original position in the forward and backward direction of the nozzle, the front end surface of the cleaning nozzle can be effectively cleaned.

  If the jet nozzle is provided below the cleaning nozzle located at the original position, the lower surface of the cleaning nozzle can be effectively cleaned. It is more effective if the shape of the jet outlet is inclined toward the cleaning nozzle.

  If the shutter has a shape having a lower surface facing portion that faces the lower surface of the cleaning nozzle and a jet port is provided in the lower surface facing portion, the lower surface of the cleaning nozzle can be more effectively cleaned.

  If the shutter with the opening opened is positioned above the cleaning nozzle, the upper surface or the tip surface of the cleaning nozzle is cleaned by ejecting liquid from the ejection port with the cleaning nozzle advanced. be able to.

It is the figure which showed the positional relationship.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the following description, the front and rear (direction) refers to the forward / backward direction of the cleaning nozzle 10 (the original position side is the rear). Up and down (direction) refers to the direction in which cleaning water is ejected from the cleaning nozzle 10 (the direction in which the cleaning water is ejected is up). The width direction means a direction orthogonal to the front-rear direction and the up-down direction. A local cleaning device 1 according to the present embodiment shown in FIGS. 1 and 2 includes a cleaning nozzle 10 and a shutter 20.

  The cleaning nozzle 10 is configured to eject cleaning water from its upper surface and clean a local part of the human body. The local cleaning device 1 according to the present embodiment includes a first cleaning nozzle 101 (for example, a bidet cleaning nozzle) and a second cleaning nozzle 102 (for example, anus cleaning nozzle). The cleaning nozzle 10 is attached in the case 30. An opening 31 corresponding to each cleaning nozzle 10 is formed in the case 30, and each cleaning nozzle 10 moves back and forth through the opening 31. Specifically, the cleaning nozzle 10 is provided so as to be movable back and forth between an original position that is the rearmost position and a cleaning position that is a position for cleaning a local part of the human body ahead of the original position. Since a well-known configuration can be applied to the drive mechanism for moving the cleaning nozzle 10 forward and backward, description thereof is omitted. The “opening” means a necessary space for the cleaning nozzle 10 to move forward and backward, and does not require a partitioned space (area) or the like as an essential requirement. That is, the space on the front side of the front end surface of the cleaning nozzle 10 located at the original position corresponds to an “opening” regardless of whether or not the space is partitioned. Although not shown, a tube through which the cleaning water flows is formed inside the cleaning nozzle 10, and the cleaning water that has passed through the tube is localized in the human body from the cleaning water outlet 11 formed on the tip side on the upper surface of the nozzle. Erupted toward.

  The shutter 20 is a member for covering the opening 31 when the cleaning nozzle 10 is located at the original position and preventing sewage and dirt from adhering to the cleaning nozzle 10. The shutter 20 is rotatably supported with respect to the case 30 above the opening 31. That is, the shutter 20 covers the front end surface of the cleaning nozzle 10 located at the original position, and is attached so as to be rotatable forward with respect to the case 30 from this state. When the cleaning nozzle 10 located at the original position moves forward, it is pushed by the moved cleaning nozzle 10 and the shutter 20 rotates forward to open the opening 31. That is, the cleaning nozzle 10 moves to the cleaning position while pushing the shutter 20 open. Since the shutter 20 is rotatably supported with respect to the case 30 above the opening 31, the shutter 20 in a state where the opening 31 is opened is positioned above the cleaning nozzle 10. The shutter 20 is provided with an urging member (not shown) that urges the shutter 20 to rotate in the original position (position covering the opening 31). The cleaning nozzle 10 returns to the original position, and the cleaning nozzle 10 When the shutter 20 is in a non-contact state, the shutter 20 in a state where the opening 31 is opened returns to the original position and covers the opening 31.

  In the local cleaning device 1 according to the present embodiment, the cleaning function of the cleaning nozzle 10 is added to the shutter 20 that protects the nozzle from being contaminated by covering the tip portion (opening 31) of the cleaning nozzle 10 located at the original position. Is added. Specifically, it is as follows. On the surface (rear surface) of the shutter 20 on the cleaning nozzle 10 side, a plurality of jets 21 through which a liquid (water in this embodiment) for cleaning the cleaning nozzle 10 can pass are formed. Further, a water supply port 22 is formed in the shutter 20. The water supply port 22 and each jet port 21 communicate with each other through an internal flow path 23 formed in the shutter 20. The water supply port 22 is connected to a water source via a water supply pipe (not shown). A valve (not shown) that can switch at least ON / OFF of the flow path is provided in the middle of the path from the water source to the water supply port 22. The water supplied to the water supply port 22 reaches each ejection port 21 through the internal flow path 23, and is ejected from each ejection port 21 toward the cleaning nozzle 10. Thereby, the cleaning nozzle 10 itself is cleaned. The above-mentioned valve may be used as a flow rate adjustment valve, and the pressure of water ejected to the cleaning nozzle 10 may be adjustable.

  As the position and shape of the ejection port 21, the following configurations are conceivable. In the configuration shown in FIGS. 3 and 4 (first embodiment), a jet port 21a is provided at a position overlapping with the front end surface of the cleaning nozzle 10 in the shutter 20a in the front-rear direction (the forward and backward direction of the cleaning nozzle 10). In the present embodiment, since the cleaning nozzle 10 has a substantially circular cross section, a plurality of jet nozzles 21a are arranged in an annular shape in accordance therewith. The axis of each spout 21a is along the front-rear direction. As described above, by disposing the plurality of jet nozzles 21a in the region overlapping with the front end surface of the cleaning nozzle 10, the front end surface of the cleaning nozzle 10 can be efficiently cleaned.

  The configuration shown in FIGS. 5 and 6 (second embodiment) is provided with a plurality of jet nozzles 21b below the cleaning nozzle 10 located at the original position in the shutter 20b. In the second embodiment, the plurality of jet nozzles 21b are arranged in the width direction. Thereby, the lower surface of the cleaning nozzle 10 can be efficiently cleaned.

  In the second embodiment, the shape of the ejection port 21b is a shape inclined toward the cleaning nozzle 10, that is, a shape inclined gradually toward the upper side from the inside (the inner flow path 23 side) of the shutter 20b to the outside. There should be. If it does in this way, since the water sprayed from the jet nozzle 21b becomes a shape which goes to the lower surface of the washing | cleaning nozzle 10, the washing | cleaning efficiency of the said lower surface will further improve. Moreover, when the inclination angle of the jet nozzle 21b is adjusted so that the water sprayed from the jet nozzle 21b is directed to the intersection line where the lower surface of the cleaning nozzle 10 and the tip surface of the cleaning nozzle 10 intersect, the tip surface of the cleaning nozzle 10 It is possible to efficiently clean the lower surface at the same time. That is, the jet port 21b may be formed so that the axis of the jet port 21b is directed to an intersection line where the lower surface of the cleaning nozzle 10 and the tip surface of the cleaning nozzle 10 intersect. In addition, even if the jet nozzle 21b does not have an inclined shape, the lower surface of the cleaning nozzle 10 can be adjusted by adjusting the pressure of water jetted from the jet nozzle 21b (adjusting the pressure so that the jetted water diverges). It is possible to wash.

  The configurations of the first embodiment and the second embodiment may be combined. That is, a plurality of jet nozzles 21 a are provided at positions where the front end surface of the cleaning nozzle 10 in the shutter 20 overlaps, and a plurality of jet nozzles 21 b are provided below the cleaning nozzle 10 located at the original position. It is good also as a structure which can wash | clean both efficiently and a lower surface. In this case, the flow of the plurality of jet nozzles 21a provided in the region overlapping the tip surface of the cleaning nozzle 10 and the plurality of jet nozzles 21b provided below the cleaning nozzle 10 are independent, and the tip surface is cleaned. It is possible to switch the cleaning of the lower surface arbitrarily.

  In addition, the cleaning function in the first and second embodiments can clean the upper surface of the cleaning nozzle 10. As shown in FIGS. 4B and 6B, when the cleaning nozzle 10 is advanced, the shutter 20 is opened by the cleaning nozzle 10. The shutter 20 that has been opened is positioned above the cleaning nozzle 10. That is, the surface of the shutter 20 on which the ejection port 21 is provided faces the upper surface of the cleaning nozzle 10. Therefore, the upper surface of the cleaning nozzle 10 can be cleaned by ejecting water from the ejection port 21 while moving the cleaning nozzle 10 forward and backward within a range in which the shutter 20 is open. That is, in the first and second embodiments, not only the front end surface or the lower surface of the cleaning nozzle 10 but also the upper surface of the cleaning nozzle 10 can be cleaned. In addition, since the upper surface of the cleaning nozzle 10 is a surface provided with a cleaning water outlet 11 for ejecting cleaning water for cleaning the local portion, there is a great demand for the user to keep the surface clean.

  The configuration (third embodiment) shown in FIG. 7 is such that a lower surface facing portion 24c that faces the lower surface of the cleaning nozzle 10 is formed on the shutter 20c, and a jet port 21c is provided on the lower surface facing portion 24c. The shutter 20 in this example has a front end surface facing portion 25 c that faces the front end surface of the cleaning nozzle 10 and a lower surface facing portion 24 c that faces the lower surface of the cleaning nozzle 10. That is, the cross-section has a shape bent in a substantially “L” shape. The lower surface facing portion 24c is formed with a plurality of jet ports 21c formed so that the axis is along the vertical direction. By setting it as such a structure, the lower surface of the washing nozzle 10 can be wash | cleaned efficiently.

  Further, the cleaning function in the third embodiment can clean the tip surface of the cleaning nozzle 10. As shown in FIG. 7B, when the cleaning nozzle 10 is moved forward, the shutter 20 c is opened by the cleaning nozzle 10. When the cleaning nozzle 10 is advanced to a predetermined position, the front end surface facing portion 25c of the shutter 20c in the opened state is positioned above the cleaning nozzle 10, and the lower surface facing portion 24c is positioned in front of the cleaning nozzle 10. . That is, the lower surface facing portion 24c of the shutter 20c is in a state of facing the front end surface of the cleaning nozzle 10. Therefore, the front end surface of the cleaning nozzle 10 can be cleaned by jetting water from the jet port 21c while maintaining this facing state. That is, in the third embodiment, not only the lower surface of the cleaning nozzle 10 but also the tip surface of the cleaning nozzle 10 can be cleaned.

  In the third embodiment, it has been described that the ejection port 21c is provided in the lower surface facing portion 24c, but it may be provided in the front end surface facing portion 25c. Examples of the arrangement of the ejection ports 21 in the distal end surface facing portion 25c can include the configurations shown in the first and second embodiments. In this case, as shown in FIG. 4B and FIG. 6B, the cleaning nozzle 10 is moved forward and backward within the range in which the shutter 20c is in the open state, and is provided on the distal end surface facing portion 25c. The upper surface of the cleaning nozzle 10 can be cleaned by jetting water from the jet nozzle 21.

  The shutter 20 in which such a jet port 21 and the internal flow path 23 are formed can be manufactured as follows, for example. The shutter 20 includes a first shutter member 201 and a second shutter member 202 (see FIGS. 4, 6, and 7) that are divided in the thickness direction. Out of the two members, the ejection port 21 is formed in the first shutter member 201 constituting the surface on the cleaning nozzle 10 side. Further, at least one of the two members is formed with a groove that becomes the internal flow path 23 (FIGS. 4, 6, and 7 have a configuration in which a groove is formed in the second shutter member 202. Indicated). One member is formed with a water supply port 22 leading to the groove. The shutter 20 in the present embodiment is obtained by bonding the two members formed in this way. The bonding of both members may be any method as long as it can prevent leakage of water entering the shutter 20. If the shutter 20 is made of resin, a technique of welding both members (such as ultrasonic waves and laser welding) without gaps may be used.

  As mentioned above, although embodiment of this invention was described in detail, this invention is not limited to the said embodiment at all, A various change is possible in the range which does not deviate from the summary of this invention.
