  According to the toilet bowl cleaning tool of any one of claims 1 to 3, the toilet bowl cleaning method of claim 4 or 5, or the toilet bowl cleaning structure of claim 6 or 7, the tip of the water injection pipe is a toilet bowl. It is inserted into the drainage conduit from the inner bottom side. Then, the tip of the water injection pipe is caught at the intermediate portion in the pipe direction of the tapered drainage pipe. At this time, since the shape of the outer peripheral cross section of the tip of the water injection pipe and the inner peripheral cross section of the drainage pipe match, the outer peripheral edge of the tip of the water injection pipe matches the inner peripheral surface of the drainage pipe. Thus, the tip of the water injection pipe is tightly fitted in the drainage pipe.

  When high pressure water is supplied through the water injection channel in the water injection pipe in this tightly fitting state, the high pressure water is ejected from the tip of the water injection pipe through the drainage pipe in the insertion direction.

At this time, the tip of the water injection pipe is tightly fitted at the intermediate portion in the pipe direction of the tapered tubular drainage pipe, so that the backflow of high-pressure water from the drainage pipe to the inner bottom of the toilet is suppressed. The Moreover, the water injection pipe is pressed in the insertion direction while being inserted into the drainage pipe.

  Then, the outer peripheral edge of the tip end portion of the water injection pipe is pressed against the inner peripheral surface of the drainage pipe line by this pressing, so that the high-pressure water flows from the gap between the water injection pipe and the drainage pipe line to the inner bottom portion of the toilet bowl. It becomes more difficult to flow back to the side. Thus, according to the toilet cleaning tool, toilet cleaning method or toilet cleaning structure of the present invention, the tip of the water injection pipe is inserted into the drainage conduit from the inner bottom side of the toilet, and the water injection pipe is inserted and pressed. By simply pushing in (push-in), it is possible to eliminate or clean clogging such as dirt and soft scale in the trap part of the toilet bowl or the drain pipe ahead of it while suppressing the backflow of high-pressure water.

  Moreover, the drainage pipe line into which the tip part of the water injection pipe is inserted and tightly fitted has a tapered tubular shape in which the inner circumferential cross section gradually decreases from the inner bottom part of the toilet toward the pipe line. Removal and removal can be performed smoothly and easily.

  In particular, according to the toilet cleaning tool of the first aspect, the water injection pipe can be pressed in the insertion direction while being inserted into the drainage pipe via the grip handle. A pressing force can be applied.

  In addition, according to the toilet cleaning tool of claim 2, since it operates in the same manner as the toilet cleaning tool of claim 1, the grip handle includes a handle body connected and fixed to the proximal end portion of the water injection pipe. The main body can be held with both hands on the outer periphery of the extending portion on both sides in the lateral direction, and a cleaner or the like can insert and press (push) the water injection pipe into the drainage pipe with both hands. For this reason, even if the reaction of the high-pressure water ejected from the tip is large, the insertion state of the water injection pipe can be maintained in a stable state with both hands.

  Further, according to the toilet bowl cleaning tool of claim 3, since it operates in the same manner as the toilet bowl cleaning tool of claim 1 or 2, a water supply channel is formed in the inner peripheral portion of the handle body. By connecting the water supply hose through the connecting portion, high-pressure water can be supplied to the water injection channel of the water injection pipe through the water supply channel.

  In addition, an opening / closing valve for opening and closing the water supply channel is provided in the handle body, and a valve operating unit for opening and closing the opening / closing valve in proximity to the opening / closing valve is also provided in the handle body. For this reason, even if the handle main body is held with both hands while the water injection pipe is inserted into the drainage pipe, the valve operating part can be operated by hand to open and close the on-off valve. A cleaner or the like can easily clean the toilet bowl alone without bothering others.

  Sometimes, the on-off valve and the valve operating unit may be capable of adjusting the opening degree of the on-off valve by operating the valve operating unit. Then, the cleaner or the like can adjust the amount of high-pressure water with his / her hand while holding the handle body.

  The toilet cleaning method according to claim 5 operates in the same manner as the toilet cleaning method according to claim 4, and also operates in the same manner as any of the toilet cleaning tools according to claims 1 to 3. The cleaning structure operates in the same manner as the toilet cleaning structure of claim 6 and also functions in the same manner as the toilet cleaning tool of any one of claims 1 to 3.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the accompanying drawings. FIG. 1 is a front view of a cleaning tool 1 according to an embodiment of the present invention.

  The cleaning tool 1 of the present embodiment includes a trap portion 53 that communicates with the drainage conduit 52 through the drainage conduit 52 that is formed in the toilet bottom 51 that is the inner bottom of the urinal 50, or the trap The drain pipe 54 communicated with the section 53 is cleaned. As shown in FIG. 1, the cleaning tool 1 mainly includes a water injection pipe 2 and a grip handle 3.

  The water injection pipe 2 is formed of a cylindrical tubular resin pipe having a linear shape when viewed from the front, and its inner peripheral portion extends from the distal end portion 4 (lower side in FIG. 1) to the proximal end portion 5 (upper side in FIG. 1). The irrigation channel 6 communicated to For example, a circular pipe made of hard vinyl chloride is used as a material for the water injection pipe 2. A grip handle 3 is connected and fixed to the base end portion 5 of the water injection pipe 2.

  The grip handle 3 is suspended from a handle main body portion 7 gripped by a user such as a cleaner and a lateral end (axial direction) center portion of the handle main body portion 7 and connected to a base end portion 5 of the water injection pipe 2. And a handle connection portion 8 to be fixed. The grip handle 3 is a tubular body having a main body portion 7 and a connection portion 8 connected to each other and formed in a T shape in front view, and the inner peripheral portions of the main body portion 7 and the connection portion 8 communicate with each other. It has become a space.

  The grip handle 3 has a base end portion 5 of the water injection pipe 2 coaxially connected and fixed to the handle connection portion 8. By this connection and fixation, the handle body portion 7 is viewed from the front of the water injection pipe 2. It is a form that is connected and fixed in a T-shape. For this reason, the handle main body 7 of the grip handle 3 is extended on both sides in the lateral direction from the connecting and fixing portion with the base end portion 5 of the water injection pipe 2, and the outer periphery of each extended portion 7a can be gripped by hand. It has become.

  Further, the grip handle 3 is formed of a T-shaped joint 9 partly formed of a resin material such as hard vinyl chloride. The T-shaped joint 9 forms a part of the handle body 7. The horizontal tube portion 9a and the vertical tube portion 9b forming the handle connection portion 8 are connected in a T shape in a front view. And the handle | steering-body main part 7 is formed by the horizontal pipe part 9a of this T-shaped coupling 9, the ball valve 10, and the one-touch coupling 11 being sequentially connected in the horizontal direction.

  Here, the handle main body portion 7 of the grip handle 3 becomes a closed end portion 12 by closing the right end portion of the horizontal pipe portion 9a of the T-shaped joint 9 that is one end portion in the axial direction (right side in FIG. 1). The socket 11a of the one-touch joint 11 is connected and fixed to the other axial end portion (left side in FIG. 1). The one-touch joint 11 is a joint that is engaged and connected when the plug 11b is detachably fitted to the socket 11a.

  Note that the plug 11b of the one-touch joint 11 is connected and fixed to an end of a water supply hose 13 that supplies high-pressure water from a water source.

  The ball valve 10 is interposed between the socket 11 a of the one-touch joint 11 and the left end portion of the horizontal pipe portion 9 a of the T-shaped joint 9. Here, the ball valve 10 has an internal flow path (not shown) for connecting the inner peripheral portion of the T-shaped joint 9 and the inner peripheral portion of the one-touch joint 11, and a ball-like shape for opening and closing the internal flow path. A valve body (not shown) and an operation lever 10a that is manually operated to adjust the opening degree of the internal flow path by rotating the valve body are provided.

  According to this ball valve 10, when the operation lever 10 a is operated by a hand holding the handle body 7, the valve body is rotated in the internal flow path, and the opening degree of the internal flow path is adjusted. The internal flow path is opened and closed and the flow rate of the high-pressure water is adjusted.

  Here, the handle body portion 7 communicates with the inner peripheral portion of the horizontal tube portion 9 a of the T-shaped joint 9, the internal flow path of the ball valve 10, and the inner peripheral portion of the one-touch joint 11 in the lateral direction. Thus, a water supply path 14 for supplying high-pressure water to the water injection path 6 of the water injection pipe 2 is formed, and this water supply path 14 is connected to the handle handle portion 8 of the grip handle 3 (the vertical pipe portion 9b of the T-shaped joint 9). The water injection pipe 6 communicates with the water injection path 6.

  Next, a connection structure 100 (hereinafter referred to as “urinal cleaning structure”) 100 between the distal end portion 4 of the water injection pipe 2 and the drainage conduit 52 of the urinal 50 will be described with reference to FIGS. 2 is a longitudinal sectional view showing the urinal cleaning structure 100, and FIG. 3 is a transverse sectional view taken along line III-III in FIG.

As shown in FIG. 2, the urinal 50 has a drainage line 52 opened in the toilet bottom 51, and the drainage line 52 is directed from the toilet bottom 51 side toward the trap part 53. Thus, the inner circumferential cross section is formed into a tapered tubular shape. And as for the cleaning tool 1, the front-end | tip part 4 of the water injection pipe 2 is inserted in the drainage pipe line 52 from the toilet inner bottom 51 side.

  The tip 4 of the water injection pipe 2 is inserted to the innermost part reachable in the direction of the drainage pipe 52, and is inserted into the drainage pipe 52 in a predetermined length. The outer peripheral edge of the distal end portion 4 of the water injection pipe 2 is in close contact with the inner peripheral surface of the drainage conduit 52 and is closely fitted to the inner peripheral portion of the drainage conduit 52.

As shown in FIG. 3, the drainage conduit 52 of the urinal 50 is formed in a tapered tubular shape in which the inner peripheral section gradually decreases as described above, and thus the circular inner peripheral section has a toilet inner bottom 51. 3 (corresponding to the circle Q in FIG. 3 (circle shown by a dotted line) in FIG. 3) compared to the side (circle P in FIG. 3 (corresponding to a circle shown by a two-dot chain line)). .) Is smaller.

  On the other hand, the distal end portion 4 of the water injection pipe 2 has an outer peripheral cross section of the distal end portion 4 that is constant in the axial direction (the vertical direction in FIG. 2 and the direction perpendicular to the paper surface in FIG. 3). An outer peripheral cross section (corresponding to a circle r in FIG. 3 (a circle indicated by a solid line so as to contact the entire inner periphery of the circle R)) is an inner peripheral cross section on the toilet inner bottom 51 side in the drainage conduit 52 ( 3 corresponding to a circle P in FIG. 3) and larger than an inner peripheral cross section (corresponding to a circle Q in FIG. 3) on the side of the trap portion 53 in the drainage conduit 52.

  And the outer peripheral cross section of the tip part 4 of this water injection pipe 2 is the inner peripheral cross section of the intermediate part (the vertical direction of FIG. 2 and the perpendicular direction with respect to the paper surface of FIG. 3) in the drainage pipe 52. It corresponds to a circle R in the drawing (corresponding to a circle indicated by a solid line so as to contact the entire outer periphery of the circle r).

  For this reason, the outer peripheral edge of the tip 4 of the water injection pipe 2 and the inner peripheral surface of the drainage pipe 52 are in close contact with each other, and the tip 4 of the water injection pipe 2 is closely fitted to the drainage pipe 52. It will be in the state. In addition, in such a close fitting state, the water injection pipe 2 is pressed toward the trap portion 53 side (the lower side in FIG. 2) by both hands of the user holding the holding handle 3, so that the close fitting state is further increased. It becomes closer.

  Next, a method for cleaning the urinal 50 using the urinal 50 cleaning tool 1 and the urinal cleaning structure 100 will be described with reference to FIGS.

  First, when cleaning the urinal 50, the cleaning tool 1 and a high-pressure water supply source (not shown) are connected. In this connection, a water supply hose 13 is connected to the handle main body portion 7 of the grip handle 3 via a one-touch joint 11, and this water supply hose 13 is connected to a water supply port of a high-pressure water supply source such as a water supply.

  On the other hand, the tip 4 of the water injection pipe 2 is inserted into the drainage conduit 52 from the toilet inner bottom 51 side. Here, the drainage conduit 52 is a tapered tube whose inner circumferential section gradually decreases from the toilet inner bottom 51 side toward the trap portion 53, that is, in the insertion direction of the water injection pipe 2. The insertion of the tip end portion 4 of the water injection pipe 2 can be guided through the inner peripheral surface.

  In this embodiment, the insertion direction or the withdrawal direction of the water injection pipe 2 is the same as the direction of the drainage conduit 52.

  When the tip 4 of the water injection pipe 2 is inserted into the drainage pipe 52 by a predetermined length, the outer peripheral edge of the tip 4 of the water injection pipe 2 matches the inner peripheral surface of the drainage pipe 52. As a result, the distal end portion 4 of the water injection pipe 2 is tightly fitted in the drainage conduit 52, and as a result, is caught at the middle portion of the tapered drainage conduit 52 in the conduit direction.

  At this time, the handle main body portion 7 of the grip handle 3 is gripped with the hands of the cleaner by the outer periphery of the extended portions 7a and 7a on both sides in the lateral direction. Then, by applying a pressing force for pushing the water injection pipe 2 into the drainage pipe line 52 through the grip handle 3, the degree of adhesion between the distal end portion 4 of the water injection pipe 2 and the drainage pipe line 52 is increased. .

  In this way, when the distal end portion 4 of the water injection pipe 2 is press-fitted tightly into the drainage conduit 52, supply of high-pressure water is started from the high-pressure water supply source via the water supply hose 13. In supplying such high-pressure water, the ball valve 10 is opened by operating the operation lever 10a.

  Then, high-pressure water is supplied to the water supply path 14 of the water injection pipe 2 through the water supply path 14 in the handle main body 7 of the grip handle 3. At this time, since the operation lever 10a of the ball valve 10 is at the hand holding the handle main body 7, the cleaner can easily open and close the ball valve 10 while holding the handle main body 7.

  Then, the high-pressure water supplied to the water injection path 6 of the water injection pipe 2 is ejected from the distal end portion 4 of the water injection pipe 2 to the trap portion 53 side via the drainage conduit 52. Due to the jet flow of the high-pressure water, the clogging such as dirt and soft scale in the trap portion 53 or the drain pipe 54 beyond the trap portion 53 is pushed away and eliminated. Moreover, since the tip end 4 of the water injection pipe 2 is tightly fitted at the intermediate portion in the pipe direction of the tapered tubular drainage pipe 52, the high-pressure water flows back from the drainage pipe 52 to the toilet inner bottom 51. Is suppressed.

  After cleaning the urinal 50, the distal end portion 4 of the water injection pipe 2 is removed from the drain line 52 of the urinal 50. In such removal, the drainage pipe line 52 into which the tip part 4 of the water injection pipe 2 is inserted and closely fitted has a tapered tubular shape in which the inner peripheral section gradually decreases from the toilet bottom 51 to the trap part 53. The distal end portion 4 of the water injection pipe 2 inserted and closely fitted into the drainage conduit 52 can be easily pulled out.

  In this way, the tip 4 of the water injection pipe 2 itself becomes a hermetic stopper that prevents the backflow of high-pressure water from the drainage conduit 52 of the urinal 50 to the toilet bottom 51, and the drainage conduit 52 of the urinal 50. As a result of being easily and quickly inserted into and removed from, the large number of urinals 50 can be easily cleaned even in places where a large number of urinals 50 are installed such as public facilities.

  Next, a modification of the above embodiment will be described with reference to FIGS. FIG. 4 is a longitudinal sectional view showing a urinal cleaning structure 300 using the cleaning tool 30 of the second embodiment, and FIG. 5 shows a urinal cleaning structure 400 using the cleaning tool 40 of the third embodiment. It is the longitudinal cross-sectional view shown.

  The cleaning tool 30 and the urinal cleaning structure 300 of the second embodiment showed means for expanding the diameter of the tip 4 of the water injection pipe 2 with respect to the cleaning tool 1 and the urinal cleaning structure 100 of the first embodiment described above. Is. In the following, the same parts as those in the first embodiment are denoted by the same reference numerals, description thereof is omitted, and only different parts are described.

  As shown in FIG. 4, the diameter-expanding member 31 has an inner diameter on the side of the trap portion 53 in the drainage pipe 52 that is larger than the outer diameter of the tip portion 4 of the water injection pipe 2. When the part 4 cannot be tightly fitted at the middle part of the drainage pipe line 52 in the pipe direction, it is fitted on the tip part 4 of the water injection pipe 2 to enlarge the outer diameter of the tip part 4.

  The diameter-expanding member 31 includes a diameter-expansion connecting part 32 into which the tip part 4 of the water injection pipe 2 is inserted and fitted and a diameter-expanding tip part that functions as a new tip part 4 of the water-injection pipe 2 after diameter expansion. 33. For example, the diameter-expanding member 31 is formed by a cylindrical joint made of resin such as hard vinyl chloride, and the outer diameter of the diameter-expanded tip portion 33 is the same as the outer diameter of the tip portion 4 of the original water injection pipe 2. It is formed larger than that.

  The cleaning tool 40 and the urinal cleaning structure 400 of the third embodiment showed a means for reducing the diameter of the distal end portion 4 of the water injection pipe 2 with respect to the cleaning tool 1 and the urinal cleaning structure 100 of the first embodiment described above. Is. In the following, the same parts as those in the first embodiment are denoted by the same reference numerals, description thereof is omitted, and only different parts are described.

  As shown in FIG. 5, the diameter reducing member 41 has an inner diameter on the side of the trap portion 53 in the drainage pipe 52 that is smaller than the outer diameter of the tip portion 4 of the water injection pipe 2, and the tip of the water injection pipe 2. When the portion 4 cannot be tightly fitted in the middle portion of the drainage pipe line 52, the outer diameter of the tip portion 4 is reduced by being fitted on the tip portion 4 of the water injection pipe 2.

  The diameter-reducing member 41 includes a diameter-reducing connection part 42 into which the tip part 4 of the water injection pipe 2 is inserted and fitted and a diameter-reducing tip part that functions as a new tip part 4 of the water-injection pipe 2 after diameter expansion. 43. For example, the reduced diameter member 41 is formed of a cylindrical joint made of resin such as hard vinyl chloride, and the outer diameter of the reduced diameter tip portion 43 is equal to the outer diameter of the tip portion 4 of the original water injection pipe 2. The size is smaller than that.

  The present invention has been described based on the embodiments. However, the present invention is not limited to the above embodiments, and various parts, materials, numerical values, sizes, shapes, and the like can be used without departing from the spirit of the present invention. It can be easily inferred that the improved deformation of can be achieved.

  For example, in this embodiment, the distal end portion 4 of the water injection pipe 2 (including the enlarged diameter distal end portion 33 of the enlarged diameter member 31 and the reduced diameter distal end portion 43 of the reduced diameter member 41; the same applies hereinafter) The distal end portion 4 of the water injection pipe 2 that is in close contact with the inner peripheral surface of the drainage conduit 52 or the outer peripheral edge of the distal end portion 4 has elasticity. You may make it form with a resin material.

  Specifically, if the tip portion 4 of the water injection pipe 2 is made of hard vinyl chloride as in the present embodiment, it can be deformed to fit the inner peripheral surface of the drainage pipe line 52 due to its inherent elastic characteristics. can do. In addition, the contact portion of the distal end portion 4 of the water injection pipe 2 with the inner peripheral surface of the drainage conduit 52 may be formed of an elastic material such as elastic rubber having higher elasticity.
