[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a toilet bowl by guiding washing water flowing through a main water supply channel to a medicine supply device via a branch pipe, and sending the cleaning water guided to the medicine supply device to a flush toilet via the branch pipe and the main water supply path. The present invention relates to a flush toilet cleaning apparatus for performing flushing.
[0002]
[Prior art]
The flushing device for flush toilets described above (hereinafter, abbreviated as "cleaning device") supplies flush water to flush toilets in order to prevent urine stones from adhering to the toilets and generating odors from the toilets. (See, for example, Patent Document 1).
[0003]
FIGS. 11 and 12 show a generally used cleaning apparatus. In the figure, reference numeral 102 denotes a main water supply channel for guiding cleaning water to the flush toilet, and reference numeral 103 denotes a branch pipe for branching and flowing the cleaning water flowing in the main water supply channel 102 to the medicine supply device 104. Reference numeral 105 denotes a flow member that guides a part of the washing water flowing through the main water supply passage 102 to the branch pipe 103.
[0004]
The flow member 105 has a semi-cylindrical shape, and is disposed inside the main water supply passage 102 at right angles to the flow direction of the washing water. Then, on the extension of the front end of the flow member 105, one end of the branch pipe 103 is arranged so as to open. When the user instructs a toilet flush, flush water flows in the main water supply channel 102 in the downward direction in the figure. This washing water collides with the flow member 105 provided in the middle of the main water supply passage 102, and flows into the branch pipe 103 while being guided by the inner peripheral surface of the flow member 105.
[0005]
The washing water that has flowed into the branch pipe 103 flows into the drug supply device 104 to dissolve a solid drug (not shown), and then flows out to the branch pipe 103. The flush water that has flowed out to the branch pipe 103 flows into the flush toilet via the main water supply channel 102. In this way, the toilet flush is completed.

[Problems to be solved by the invention]
However, in the above-described cleaning apparatus, since the branch pipe 103 is disposed on an extension of the tip of the flow member 105, it is difficult to control the flow rate of the cleaning water. That is, since there is a gap between the flow member 105 and the branch pipe 103, a part of the washing water flows down from this gap, and the flow rate of the washing water sent to the medicine supply device 104 decreases. For this reason, the flow rate of the washing water flowing into the flush toilet may be insufficient, which may cause problems such as adhesion of urine stones to the flush toilet and generation of offensive odor.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, a cleaning device of the present invention includes a joint connected to a main water supply passage for supplying flush water to a toilet, a branch pipe connected to the joint, and a connection connected to the branch pipe. A medicine supply device for mixing a medicine into the washing water flowing through the branch pipe, and discharging the medicine-containing washing water to the main water supply passage through the branch pipe; A guide member for guiding washing water flowing in the water supply channel to the branch pipe, wherein the guide member has a v-shaped cross section in a direction perpendicular to the longitudinal direction, one end of which is attached to the joint portion, and the other end Is inserted into the branch pipe.
[0009]
As described above, in the present invention, since the other end of the guide member is inserted into the branch pipe, it is unlikely that the washing water flows down from the gap between the guide member and the branch pipe as in the above-described related art. Therefore, a sufficient amount of washing water can be sent to the medicine supply device.
[0010]
Further, in the above invention, it is preferable that the guide member is attached to the joint so as to be rotatable about its longitudinal axis as a rotation axis so that the flow rate of the washing water guided to the branch pipe can be adjusted.
[0011]
The portion of the guide member inserted into the branch pipe may be brought into contact with the inner peripheral surface of the branch pipe.
[0012]
In order to facilitate the mounting of the washing machine, an extension may be provided at the joint portion, through which washing water flows, and the extension may be inserted into an insertion portion provided on the upper surface of the flush toilet.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
(1st Embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a flush toilet flushing device according to a first embodiment of the present invention and a flush toilet to which the flushing device is attached.
[0014]
In the figure, reference numeral 11 denotes a flush toilet, and a spat 12 for screwing a joint 13 is provided on an upper surface of the flush toilet 11. A lower end of a main water supply pipe 14 extending in the vertical direction in the figure can be in close contact with an upper end of the joint 13. One end of a branch pipe 16 extending in the left-right direction in the figure is screwed into 13.
[0015]
At the other end of the branch pipe 16, a medicine supply device 18 is attached via a cap valve portion 17, and the medicine supply device 18 stores a solid medicine (not shown) for washing the flush toilet 11. ing. A guide member (not shown in FIG. 1) is attached to the inside of the joint 13 so that the washing water flowing through the main water supply pipe 14 can be guided to the branch pipe 16.
[0016]
Next, the structure of the joint 13 will be described in detail with reference to FIGS. The joint 13 is a cylindrical joint that connects the main water supply pipe 14 and the branch pipe 16. A screw portion 13 a for screwing the hexagonal screw 15 is formed on the upper outer peripheral surface of the joint 13, and a screw portion 13 b for screwing into the spat 12 is formed on the lower inner peripheral surface.
[0017]
When attaching the main water supply pipe 14 to the joint 13, a hexagonal screw 15 is fitted into the main water supply pipe 14, and the lower part of the main water supply pipe 14 is inserted into the upper opening of the joint 13. You can screw it in. At the center of the joint 13, a screw hole 13c for screwing the branch pipe 16 and a guide member insertion hole 13d for inserting the guide member 19 are provided.
[0018]
Next, the structure of the guide member 19 will be described in detail. The guide member 19 has a guide portion 19a having a v-shaped cross section in the direction perpendicular to the longitudinal direction, and a guide member support portion 19b inserted into the guide member insertion hole 13d to support the guide member 19. .
[0019]
As shown in FIG. 2, the distal end of the guide member 19 is in contact with the inner peripheral surface of the branch pipe 16 at the top A, the side end B, and the side end C. Thereby, since both ends of the guide member 19 are supported by the branch pipe 16 and the joint 13, the risk of breakage and the like is reduced. That is, in the above-described conventional technology, the flow member is supported by attaching one end thereof to the joint, but the guide member 19 of the present embodiment collides from above because both ends thereof are supported by the joint 13 and the branch pipe 16. The maximum bending moment received by the cleaning water can be kept low. Therefore, a highly durable cleaning device can be provided.
[0020]
Since the slope portion D provided on the guide member 19 does not contact the inner peripheral surface of the branch pipe 16, a gap is generated between them. Therefore, the washing water flowing into the branch pipe 16 via the medicine supply device 18 is supplied to the flush toilet 11 through this gap.
[0021]
A groove 192 for abutting the tip of a flathead screwdriver from outside the joint 13 is formed in the guide member support 19b. When rotating the guide member 19 around its longitudinal axis, the guide member 19 may be rotated by abutting the tip of a flathead screwdriver against the groove 192.
[0022]
Thus, in this embodiment, the guide member 19 can be rotated around its longitudinal axis. Thereby, the receiving area of the washing water can be changed according to the rotation angle of the guide member 19, so that the flow rate of the washing water guided by the guide member 19 can be reliably controlled. That is, since overflow occurs when the amount of washing water flowing into the medicine supply device 18 is too large, it is usually necessary to control the flow rate of washing water flowing through the main water supply passage. By changing the flow rate, the flow rate of the washing water flowing into the medicine supply device 18 can be controlled. Therefore, it is not necessary to pay much attention to the flow rate of the washing water flowing through the main water supply passage.
[0023]
Near the groove 192, a minute concave portion 193 for determining the water receiving area of the guide member 19 from outside the joint 13 is provided. When the minute concave portion 193 approaches the upper end of the joint 13, the contact area between the inner peripheral surface of the guide portion 19 a and the washing water increases, so that the water receiving area increases. Since the contact area between the peripheral surface and the washing water is reduced, the water receiving area is reduced. Thereby, the flow rate of the washing water flowing into the medicine supply device 18 can be controlled more reliably.
[0024]
An O-ring 21 made of an elastic material is fitted into the guide member support 19b. When the guide member support portion 19b is inserted into the guide member insertion hole 13d, the O-ring 21 is engaged with the guide member insertion hole 13d, so that it is possible to prevent the washing water from leaking from the joint 13.
[0025]
Next, the structure of the medicine supply device 18 used in the present embodiment will be described in detail with reference to FIGS. In these figures, reference numeral 211 denotes a box-shaped container having an open upper end. As shown in FIG. 4, a valve body 225 having a water passage hole 225a extending vertically is attached to the center of the bottom surface 211a of the container, and an inside diameter of the water passage hole 225a is provided in the water passage hole 225a. The shaft 220a of the valve movable body 220 having a smaller outer diameter is inserted so as to be vertically movable. A flat cylindrical float portion 220b is provided at an upper end of the shaft portion 220a, and a frustoconical opening / closing portion 220c is provided at a lower end of the shaft portion 220a.
[0026]
Further, a valve receiving portion 225b is formed at a lower end portion of the water passage hole 225a of the valve main body 225 so that the slope of the opening / closing portion 220c of the valve movable body 220 comes into close contact with and separates therefrom. The switching valve is constituted by the valve main body 225 and the valve movable body 220.
[0027]
Further, on the left and right sides of the bottom surface 211a of the container 211 with the switching valves 220 and 225 interposed therebetween, a scaffold-shaped medicine support base 214 is formed. As shown in FIG. 5, the upper surface 214a of the medicine support table 214 is located higher than the bottom surface 211a of the container 211.
[0028]
The groove 214b of the medicine support base 214 extends in the left-right direction, that is, the direction toward the switching valves 220 and 225 and the side surface of the container 211. As shown in FIG. 6, a cubic or rectangular solid medicine Y is placed on the upper surface 214a of each medicine support table 214 thus formed.
[0029]
Further, a comb-shaped drug stopper 215 extending upward from a position adjacent to the switching valves 220 and 225 on the bottom surface 211a of the container 211 on the left and right sides (the position of the inner end in the left-right direction of the medicine support base 214). , 225 are provided. Note that the medicine support table 214 and the medicine stopper 215 are formed integrally with the container 211. Further, in the container 211, the two parts on the left and right where the medicine support base 214 and the medicine stopper 215 are formed are medicine placement parts.
[0030]
A fragrance support 230 is provided at the upper center of the container 211 in the left-right direction so as to extend in the front-rear direction. At the rear of the fragrance support 230, an inclined surface 230a that is higher toward the front is formed. A flat lattice-shaped fragrance cassette 240 in which a fragrance is sealed is placed on the inclined surface 230a.
[0031]
Reference numerals 251, 252, and 253 denote an outer cover main body, a lower outer cover, and an upper outer cover which cover the entirety of the fragrance cassette 240 placed on the inclined surface 230 a of the container 211 and the fragrance support table 230, respectively.
[0032]
The outer cover main body 251 has a height corresponding to the height of the lower outer cover 252 and the upper outer cover 253, and is fixed to the wall surface of the toilet by screws or the like on the back surface. In addition, a concave curved surface portion 251a is formed on the front side of the upper end portion of the outer cover body 251.
[0033]
The lower outer cover 252 is fixed to the lower front surface of the outer cover body 251 by bonding or the like. As shown in FIG. 4, a snap engagement claw that is elastically movable in the front-rear direction is provided on the rear side of the center of the lower exterior cover 252 in the left-right direction (a position facing the front part of the fragrance support table 230). The base end of 255 is fixed by bonding or the like.
[0034]
A claw engaging portion 253b for engaging the claw portion of the snap engagement claw 255 is formed on the front side of the front surface of the upper exterior cover 253 shown in FIG. An engagement release hole 253a is formed above the engagement portion 253b on the front surface.
[0035]
The upper outer cover 253 has a guide rail 253d formed on the back side of the left and right sides of the upper outer cover 253 from above the outer cover body 251 and the lower outer cover 252, and a guide groove formed on the upper side of the outer cover body 251. By moving it downward while inserting it into the outer cover body 251 and the lower outer cover 252, the claw engaging portion 253 b is engaged with the claw portion of the snap engagement claw 255. Between the upper rear side of the upper outer cover 253 thus attached and the concave curved surface portion 251a of the outer cover body 251 is opposed to the surface of the fragrance cassette 240 mounted on the inclined surface 230a of the fragrance support table 230. An air passage 257 is formed.
[0036]
In order to prevent dust or the like from entering from the air passage 257, a plurality of dust removal plates 253c are formed in the left and right direction on the rear side of the upper rear side of the upper exterior cover 253.
[0037]
When removing the upper outer cover 253 to replenish the solid medicine Y or replace the fragrance cassette 240, a tool such as a pin is inserted into the engagement release hole 253a of the upper outer cover 253, and a snap lock is inserted. The engagement between the snap engagement claw 255 and the claw engagement portion 253b of the upper outer cover 253 may be released by pushing the dowel 255 backward.
[0038]
Next, the operation of the medicine supply device configured as described above will be described with reference to FIG. FIG. 7A shows a state before the washing water flows into the container 211. In this state, the float portion 220b of the valve movable body 220 moves downward until it comes into contact with the upper end surface of the valve body 225. Further, at this time, the opening / closing portion 220c of the valve movable body 220 is separated from the valve receiving portion 225b of the valve body 225, and the washing water is allowed to flow into the water passage hole 225a.
[0039]
When the user of the flush toilet 11 presses a switch button (not shown), for example, after adding a service, the flush water moves downward through the main water supply pipe 14. Since the guide member 19 is provided in the middle of the main water supply pipe 14, a part of the washing water collides with the guide member 19 and flows into the branch pipe 16 while being guided by the inner peripheral surface of the guide portion 19a. The cleaning water flowing into the branch pipe 16 flows into the water passage hole 225a of the valve body 225. When the pressure of the washing water flowing into the water channel hole 225a is received by the float portion 220b, the valve movable body 220 is pushed up, the upper end of the water channel hole 225a is opened, and the cleaning water W flows into the container 211. The solid medicine Y dissolves in the washing water W flowing into the container 211, and the washing water in the container 211 becomes the washing water containing the medicine. As the level of the washing water W flowing into the container 211 increases, the float 220b floats on the washing water W, so that the valve movable body 220 gradually moves upward.
[0040]
Here, in the present apparatus, since the solid medicine Y is placed on the medicine supporting table 214 in the shape of a scale, the washing water W of the solid medicine Y is smaller than when the solid medicine is placed directly on the bottom surface of the container 211. Contact surface area with the substrate can be increased. Therefore, even if the time for dissolving the solid medicine Y in the washing water W (the time from when the washing water starts flowing into the container 211 to when the outflow of the washing water ends) is short, washing with a sufficient concentration of the medicine is performed. Water W can be made in the container 211 and supplied to the flush toilet 11.
[0041]
Further, when the washing water W flows into the container 211, there is a possibility that the solid medicine Y moves in the container 1 in a direction approaching the switching valves 220 and 225 due to the force of the water flow. However, in the present apparatus, since the solid medicine Y is reliably prevented from interfering with the switching valves 220 and 225 by the medicine stopper 215, the solid medicine Y is caught by the switching valves 220 and 225, and the like. There is no situation where the operation of the H.225 is hindered. When the washing water W starts to flow into the container 211, the air A in the container 211 or the outer covers 251 to 253 is pushed out toward the air passage 257. Since the fragrance cassette 240 is disposed so as to face the air passage 257, the extruded air A is discharged from the air passage 257 to the outside of the apparatus in a state where the fragrance is efficiently passed through the fragrance cassette 240. You.
[0042]
When the washing water W flowing into the container 211 reaches a predetermined amount in this way, the opening / closing portion 220c of the valve movable body 220 comes into close contact with the valve receiving portion 225b of the valve body 225 and closes the water passage hole 225a. Inflow to the inside stops.
Thereafter, when the supply of the flush water to the flush toilet 11 is stopped, as shown in FIG. 7 (c), the pressure in the branch pipe 16 decreases, so that the valve movable body 220 moves down slightly by its own weight, The opening / closing portion 220c that has been in close contact with the valve receiving portion 225b of the main body 225 is separated therefrom. Thus, the cleaning water W containing the medicine in the container 211 is supplied from the container 211 to the branch pipe 16 through the water passage hole 225a.
[0043]
Here, the washing water W flowing into the branch pipe 16 starts flowing out to the flush toilet 11, and the valve movable body 220 also gradually moves down as the water level in the container 211 decreases. In this way, most of the medicine-containing cleaning water W in the container 211 is supplied to the flush toilet 11 to prevent adhesion of urine stones to the flush toilet 11 and the like.
[0044]
By the way, as described above, in the present embodiment, a gap is provided between the slope portion D provided on the guide member 19 and the inner peripheral surface of the branch pipe 16. Therefore, the washing water flowing through the branch pipe 16 discharged from the medicine supply device 18 flows into the flush toilet 11 through this gap. Thereby, the washing water accumulated in the medicine supply device 18 can be quickly sent to the flush toilet 11.
[0045]
Here, guide members shown in FIGS. 8 and 9 can be used. FIG. 8 shows a guide portion 1001 having a semicircular cross section in the direction perpendicular to the longitudinal direction. The distal end portion of the guide portion 1001 has a small thickness, so that the distal end portion of the guide portion 1001 can be inserted into the branch pipe 16. When the distal end of the guide portion 1001 is inserted into the branch pipe 16, the outer peripheral surface of the distal end comes into contact with the inner peripheral surface of the branch pipe 16. Thereby, both ends of the guide member are supported by the branch pipe 16 and the joint 14.
[0046]
FIG. 9 shows the guide portion 1011. Reference numeral 1011 a denotes a flat guide surface that receives the cleaning water supplied from the main water supply pipe 14 and guides the water to the branch pipe 16. Reference numeral 1011b denotes a flat water-stop portion formed so as to rise from the outer edge of the guide surface 1011a. The direction of the flow of the cleaning water flowing through the guide surface 1011a is controlled by the water stop portion 1011b, and flows into the branch pipe 16.
[0047]
The distal end of the guide portion 1011 is cut out so that the length of the guide member in the short direction is substantially equal to the inner diameter of the branch pipe 16, whereby the distal end of the guide section 1011 is inserted into the branch pipe 16. I can do it. When the distal end of the guide portion 1011 is inserted into the branch pipe 16, the distal end contacts the inner peripheral surface of the branch pipe 16. Thereby, both ends of the guide member are supported by the branch pipe 16 and the joint 14.
[0048]
By using the guide portions (1001, 1011) supported at both ends, a washing machine with excellent durability can be provided, but the supply of the washing water to the flush toilet 11 is delayed compared to the guide member 19 of the present embodiment. I understood.
[0049]
This is because the outer peripheral surface of the distal end portion of the guide portion 1001 and the inner peripheral surface of the branch pipe 16 are in contact with each other. It is thought that it is to temporarily accumulate at 16.
[0050]
(2nd Embodiment)
FIG. 10 shows a cleaning device of the present embodiment and a flush toilet to which the cleaning device is attached. A joint 30 connects the main water supply pipe 14 and the branch pipe 16. A screw groove 30a is formed on the upper outer peripheral surface of the joint 30, and a hexagon screw 31 is screwed into the screw groove 30a.
[0051]
An extension pipe 30b having a constant inner diameter is provided below the joint 30.
A spat 32 is provided on the upper surface of the flush toilet 11, and a screw portion 32 a for screwing a hexagon screw 33 is formed on an outer peripheral surface of the spat 32. The spat 32 is provided with an insertion hole 32b having an inner diameter slightly smaller than the outer diameter of the extension tube 30b, and the extension tube 30b is inserted into the insertion hole 32b.
[0052]
Next, how to attach the washing device to the flush toilet 11 will be described. First, the hexagonal screw 33 in which the packing 34 is accommodated is fitted into the extension tube 30b. At this time, since the length of the extension pipe 30b in the vertical direction in the drawing is longer than the length of the hexagon screw 33 in the drawing, the distal end of the extension pipe 30b extends from the lower opening of the hexagon screw 33. It will be in a protruding state. Next, the distal end of the extension tube 30b is inserted into the opening 32a provided in the spat 32, and the hexagonal screw 33 is rotated using a spanner or the like and screwed into the screw portion 32b. This screwing operation is performed until the packing 34 is sandwiched between the inner upper surface of the hexagonal screw 33 and the upper end of the spat 32, and the operation of attaching the cleaning device is completed.
[0053]
Thus, in this embodiment, the washing apparatus can be attached to the flush toilet simply by inserting the extender 30b into the opening 32a and rotating the hexagonal screw 33. Therefore, the work of attaching the cleaning device is facilitated.
[0054]
【The invention's effect】
As described above, according to the present invention, the washing water guided by the guide member can be stably sent to the medicine supply device, and the toilet can be effectively cleaned.
