Description

  The present invention relates to a toilet device including a tank cover that covers a detergent tank attached to a toilet bowl so as to be freely opened and closed.

  Conventionally, a tank holder that detachably holds the detergent tank is installed in the side cover of the toilet bowl, and the detergent supplied from the detergent inlet / outlet part of the detergent tank is mixed with the washing water flow path to foam the foam generating liquid. Japanese Patent Application Laid-Open No. H10-228561 is known that cleans the bowl of the toilet bowl.

  By the way, since the detergent in the detergent tank is reduced by the use of the detergent, it is necessary to replenish the detergent tank with the detergent. Therefore, in the conventional example shown in Patent Document 1, the side cover on the left side of the toilet bowl is required. The tank cover that is locked to the door is opened so that the detergent is replenished from the detergent replenishing port of the detergent tank protruding outward from the toilet.

  However, the space between the outer surface of the toilet and the wall surface of the toilet room is generally narrow, and when you hold a container with detergent in one hand and supply it to the detergent replenishment port of the detergent tank, you often spill detergent. Spilled detergent may enter the toilet along the side of the detergent tank, and the entered detergent may cause rust and corrosion of parts such as the frame inside the toilet. For this reason, conventionally, it has been necessary to periodically remove the side cover and clean the inside of the toilet, which is particularly difficult in a narrow toilet room. Also, it is necessary to clean the tank cover regularly because detergent easily accumulates on the inner wall of the bottom wall of the tank cover, and the accumulated detergent may enter the toilet bowl and adhere to the surface of the detergent tank. .

  The present invention has been made in view of the above circumstances, and the purpose thereof is to prevent the detergent hanging outside the detergent tank from entering the toilet bowl when the detergent tank is attached to the toilet tank. It is possible to provide a toilet device excellent in cleanability that can save the trouble of periodic cleaning of the inside of the toilet and cleaning of the tank cover.

  In order to solve the above-mentioned problems, the present invention attaches the detergent tank 3 to the side surface of the toilet bowl 10 so that the detergent replenishing port 3b protrudes to the outer side B of the toilet bowl 10, and can open and close the detergent tank 3 freely. The tank cover 5 covering the urinal 10 is disposed so as to protrude outward B of the toilet 10, and hangs down inside the tank cover 5 on the bottom wall 5a of the tank cover 5 protruding outward B of the toilet 10. The detergent discharge portion 26 for discharging the detergent to the outer side B of the toilet bowl 10 is formed, and the bottom surface inner surface 5b of the tank cover 5 is the lowest at the portion where the detergent discharge portion 26 is formed. It is characterized by being inclined so as to become higher as it gets away from.

  By adopting such a configuration, the detergent leaked to the outside of the detergent tank 3 and dropped inside the tank cover 5 when the detergent is replenished is collected on the inclined bottom wall inner surface 5b of the tank cover 5, and the inclined gradient of the bottom wall inner surface 5b. Is discharged from the detergent discharge portion 26 formed at the lowest position to the outer side B of the toilet bowl 10. Accordingly, there is no risk of the detergent entering the toilet 10, and the position where the detergent hangs from the detergent discharge portion 26 is determined at a fixed position on the outer side B of the toilet 10, so that the detergent can be easily wiped off. . Further, since the detergent hardly accumulates in the tank cover 5, it is possible to prevent the detergent tank 3 from being stained with detergent.

  In addition, the detergent cover 26 is formed on the bottom wall 5a portion farthest from the toilet bowl 10 by inclining the bottom wall inner surface 5b of the tank cover 5 so as to become lower toward the outer side B of the toilet bowl 10. preferable. In this case, since the position where the detergent hangs from the detergent discharge unit 26 can be moved away from the toilet 10, the entry of the detergent into the toilet 10 can be reliably prevented.

  Further, on the bottom wall 5a side of the tank cover 5, there is provided a rotating means 50 that supports the tank cover 5 so as to be openable and closable toward the outer side B of the toilet bowl 10, and the tank cover 5 rotated to the open position, It is preferable to expose the detergent replenishing port 3b of the detergent tank 3 from between the side cover 16 of the toilet bowl 10. In this case, the detergent replenishment operation to the detergent replenishment port 3b can be easily performed without removing the tank cover 5 from the toilet bowl 10, and the detergent that has been spilled or dripped to the side of the detergent tank 10 when the detergent is replenished can be opened. The liquid drips into the cover 5 and is discharged from the detergent discharge portion 26 to the outer side B of the toilet bowl 10.

  The present invention is provided with a detergent discharge part for discharging the detergent hung outside the detergent tank to the outside of the toilet bowl when the detergent is replenished on the tank cover arranged to protrude outward from the toilet bowl. Intrusion of the detergent is prevented, and it is possible to prevent rust and corrosion of parts such as a frame inside the toilet bowl due to the detergent. As a result, it is not necessary to periodically clean the toilet bowl. Further, by dropping the detergent from the detergent discharge portion at a fixed position on the outer side of the toilet bowl, the detergent can be easily wiped off, and the detergent does not easily accumulate on the inner surface of the tank cover, thereby improving the cleaning property.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  As shown in FIG. 9, the toilet device 1 of the present example has a flushing water discharge device 11, a local cleaning device (not shown), and a trap device 13 provided with a detergent supply means 2 for the toilet 10 constituting the main body. This is a flush toilet constructed by arranging various devices such as these together.

  The toilet 10 is covered with a housing that accommodates the various devices 11, 13, etc. The housing of this example is made of synthetic resin, and a bowl portion 15 that opens to the upper surface is provided in the front region of the toilet device 1. It has been. In the rear area of the toilet device 1, a device storage portion 17 that is a space surrounded by a bowl forming part 15 a and a side cover 16 described later is formed, and the cleaning water spouting device 11 and the local cleaning are performed on the device storage portion 17. A device and a trap device 13 are housed and arranged. Here, the bowl forming part 15a that forms the bowl portion 15 and the side cover 16 that forms the outer shell of the toilet device 1 are integrally formed by welding.

  The trap device 13 is provided in a lower area of the device storage unit 17. The trap device 13 of this example is a turn trap system that can be expected to save water, that is, a flexible trap cylinder 19 connected to a drain cylinder 18 projecting backward from the lower part of the bowl 15 by a motor. It has a structure that can be pivoted up and down to drain the accumulated water 35 in the bowl portion 15.

  The cleaning water discharge device 11 is provided in the upper region of the trap device 13 in the device storage unit 17. Here, the rear upper part of the toilet bowl 10 is a rising part 20 that rises above the upper surface level of the bowl part 15, and the apparatus storage part 17 that accommodates the washing water spouting device 11, the local washing apparatus, and the like can be widely used. It has a structure. A toilet seat 21 and a toilet lid 22 positioned on the bowl portion 15 are pivotally supported at both end portions in the left-right direction of the rising portion 20 so as to be freely tilted. In the lower edge portion of the front portion of the rising portion 20 facing the rear edge of the opening edge of the bowl portion 15, a washing water discharge port 23 of the washing water spouting device 11 for flowing the bowl washing water after the stool is opened.

  The washing water discharge device 11 of this example is a tankless system that can be expected to be downsized. That is, the washing water discharge device 11 has a washing water flow path 24 from the water supply as a water source to the bowl portion 15 and is disposed in the washing water flow path 24. A structure in which the bowl washing water can be discharged into the bowl portion 15 from the washing water discharge port 23 at the downstream end of the washing water flow path 24 by opening and closing the water opening / closing valve 25 is employed. In the case of this tankless system, the tap water pressure can be used as it is as the conveying pressure of the bowl cleaning water, or the cleaning water can be pumped by providing a pumping pump in the cleaning water passage 24. Other structures, for example, a tank type in which stored water in a low tank as a water source is allowed to flow through an on-off valve can also be adopted. Note that the opening / closing operation of the cleaning water opening / closing valve 25 of the cleaning water discharging device 11 and the turning operation of the trap cylinder 19 of the trap device 13 are performed in the device storage unit 17 based on the operation of the operation unit (not shown) of the user. It is appropriately controlled by an internal control unit (not shown). Since the washing water discharge port 23 is provided on one side in the width direction at the rear edge of the opening edge of the bowl portion 15, the discharged bowl washing water becomes a swirling flow that swirls vigorously in the bowl portion 15, The filth in the bowl part 15 can be made to flow at a stretch.

  Furthermore, as shown in FIG. 10, the cleaning water spouting device 11 of the present example is a microscopic device that mixes air into the bowl cleaning water and refines the air to generate fine bubbles to be contained in the bowl cleaning water. Bubble generating means 27 is provided. When fine bubbles are contained in the bowl washing water, the water-saving effect due to the decrease in bulk specific gravity, the noise reduction due to the friction reduction when the bowl washing water collides with the inner surface of the bowl portion 15, and the water splash prevention effect are of course fine. Due to the shock wave generated when the bubbles collide with the inner wall of the bowl portion 15 and burst, the bubble cleaning effect that strongly removes and adsorbs the dirt attached to the inner wall of the bowl portion 15 can be expected. .

  Specifically, as shown in FIG. 10, the fine bubble generating means 27 is constituted by a pipe member 27a in which an air mixing part 28 is provided in the washing water flow path 24 and a venturi-shaped pressure suddenly changing part 29 is provided downstream thereof. Is done. The aeration unit 28 is formed by connecting an air supply pipe 31 provided with a check valve 30 (FIG. 9) around the nozzle unit 28a having a reduced diameter of the cleaning water flow path 24. By the negative pressure generated in the nozzle unit 28a. Air can be thoroughly mixed into the bowl washing water. The sudden pressure change portion 29 has a structure in which a reduced diameter portion 32 for reducing the diameter, a throat portion 33 for the reduced diameter, and an enlarged diameter portion 34 for increasing the diameter are connected in order from the upstream side. When the bowl cleaning water flows through the sudden pressure change portion 29, the air mixed in the bowl cleaning water is first inflated by the internal pressure drop in the reduced diameter portion 32 and the throat portion 33, and then in the enlarged diameter portion 34. As the internal pressure rises, shearing force and shock waves are applied to crush and refine. As the fine bubble generating means 27, a type in which the mixed air is dissolved in the bowl washing water and then precipitated can be used. However, since this type requires a dissolution tank, the size increases. A type composed of a tube material 27a that uses a shearing force or the like to crush and refine the mixed air can be suitably used.

  In the detergent supply means 2, a detergent supply path 8 extending from the detergent tank 3 is connected to the detergent mixing section 7 provided in the washing water flow path 24, and drives the detergent pump 36 provided in the detergent supply path 8 and supplies detergent. The detergent on-off valve 37 provided in the passage 8 is opened, so that the detergent mixing unit 7 mixes the detergent made of the liquid neutral detergent stored in the detergent tank 3 with the bowl washing water, thereby mixing the detergent. Has been generated. Specifically, the detergent supply path 8 of this example has a circulation path section 38 in which the start end of the forward path section and the termination end of the return path section are located in the detergent tank 3, and the wash water flow path 24 branched from the middle of the circulation path section 38. And a supply path 39 leading to the detergent mixing section 7. The detergent pump 36 is provided in the circulation path section 38, and the detergent opening / closing valve 37 is provided at the downstream end of the supply path section 39. When the detergent pump 36 is driven, the detergent stored in the detergent tank 3 circulates in the circulation path portion 38, so that the detergent is prevented from clogging due to solidification or the like in the detergent supply path 8. Further, the detergent mixing unit 7 is a part that generates a negative pressure in the bowl washing water that flows by narrowing the diameter of the washing water channel 24, and is configured by the throat part 33 of the pipe material 27a in this example. The detergent opening / closing valve 37 is opened when a negative pressure is applied to the bowl washing water in the detergent mixing section 7 and when the detergent pump 36 is driven and the pump pressure is applied. It gets mixed in the washing water.

  The detergent mixed water is supplied into the bowl portion 15 from the cleaning water discharge port 23 via the cleaning water flow path 24. As described above, the detergent mixed water discharged from the washing water discharge port 23 is swirled and travels to the inner surface of the bowl portion 15, or the detergent cleaning effect of the detergent contained in the detergent mixed water is exerted on the bowl portion 15. Effective cleaning is possible by making the inner surface fully visible. Furthermore, the detergent mixed water has an effect that the surface tension (viscosity) of the water is lower than that of the bowl washing water, and the diameter of the fine bubbles generated by the fine bubble generating means 27 can be reduced from the mm order to the μm order. . The microbubbles on the order of μm have the property that they are much harder to break than the microbubbles on the order of mm. Therefore, in the toilet apparatus 1 of the present example, the dewatered water in which the detergent mixture water is generated at the timing when the dewatered water 35 is formed in the bowl portion 15 in the cleaning operation of the bowl portion 15 and the bubbles remain for a long time. Control is performed by the control unit so as to prevent the adhesion of dirt in the vicinity of the draft line of the stored water 35.

  By the way, since the detergent is reduced by the use of the detergent supply means 2, the detergent tank 3 needs regular maintenance such as replenishing the detergent.

  Here, in this embodiment, as shown in FIGS. 5 and 6, one side cover 16 disposed on the tank holder 4 side among the side covers on both sides covering the outer surface of the toilet 10 has a protruding hole. 16a is formed. The protruding hole 16a is formed at a position corresponding to the tank holder 4, and is formed in a rectangular shape in side view.

  As shown in FIG. 4, the detergent tank 3 of the present example has a small outward protruding portion 3 </ b> B having a small capacity projecting in an L shape from a part of a wide body portion 3 </ b> A having a large capacity. In a state where the portion 3A is held by the tank holder 4, the outward projecting portion 3B is arranged to project from the projecting hole 16a to the outer side B of the toilet bowl 10. As shown in FIG. 1, the outward projecting portion 3 </ b> B of this example is inclined so as to move away from the toilet 10 toward the outer side B as it goes from the lower part to the upper part. A mouth portion 3b is provided. Further, a recess 3c (FIG. 1) is formed at the boundary between the lower surface of the outward projecting portion 3B and the lower surface of the main body portion 3A, and the detergent hanging from the side surface of the outward projecting portion 3B to the lower surface is due to the presence of the recess 3c. 1 cannot move to the lower surface side of the main body portion 3A, and therefore, it hangs down from the side surface of the outward projecting portion 3B into the tank cover 5 in the direction indicated by the arrow A in FIG. ´ does not flow down.

  The box-shaped tank cover 5 covering the detergent tank 3 is locked to the side cover 16 in a state of protruding toward the outer side B of the toilet 10, and the inner surface of the tank cover 5 and the detergent tank 3 are also in the closed position. A sufficient clearance is maintained between the surface of the detergent tank 3 and the surface of the detergent tank 3 is prevented from being contaminated by the detergent attached to the inner surface of the tank cover 5.

  As shown in FIGS. 1 to 4, a detergent discharge portion 26 is formed on the bottom wall 5 a of the tank cover 5 to discharge the detergent hanging from the side surface of the detergent tank 3 to the outer side B of the toilet bowl 10. . The detergent discharge portion 26 of this example is formed of a through hole 26 a penetrating the tank cover 5, and one end of the through hole 26 a communicates with the internal space of the tank cover 5 and the other end communicates with the outer side B of the toilet bowl 10. Further, the entire bottom wall inner surface 5 b of the tank cover 5 is inclined so that the portion where the detergent discharge portion 26 (through hole 26 a) is formed is the lowest and becomes higher as it moves away from the detergent discharge portion 26.

  In the example shown in FIG. 2, the bottom wall inner surface 5b of the tank cover 5 has both side inclined portions 5c, 5c inclined downward from the left and right sides toward the center, and gradually decreases from the rear end toward the front end. That is, a bowl-shaped central inclined portion 5d that is inclined so as to become lower toward the outer side B of the toilet bowl 10 is formed. The slopes of the inclined portions 5c and 5d are, for example, about 5 ° in a state where the tank cover 5 is held at the closed position.

  Further, on the side of the bottom wall 5a of the tank cover 5, there is provided a rotating means 50 that rotatably supports the tank cover 5 so as to be opened and closed toward the outer side B of the toilet bowl 10. The rotating means 50 of this example is composed of a substantially C-shaped lower locking claw 53 that protrudes from the left and right portions of the rear end portion of the bottom wall 5a of the tank cover 5 and is bent downward, as shown in FIG. The side cover 16 is detachably hooked and locked to the locked portion 61 provided at the lower edge portion of the protruding hole 16a. By rotating the tank cover 5 around the lower locking claw 53 in the opening direction, the detergent replenishing port 3b of the detergent tank 3 is exposed between the tank cover 5 and the side cover 16 of the toilet bowl 10. Yes. The opening angle of the tank cover 5 is about 45 ° to 90 °, but is not limited to this, and may be any opening angle that exposes at least the detergent replenishing port 3b of the detergent tank 3.

  As shown in FIG. 1, the means for locking the tank cover 5 in the closed position comprises an upper locking claw 51 projecting rearward from the rear end portion of the upper wall 5e of the tank cover 5. At the closed position of the cover 5, the upper locking claw 51 is hooked and locked by a locking tool 70 fixed inside the protruding hole 16 a of the side cover 16 of the toilet 10. The allowance of the upper locking claw 51 to the locking tool 70 is set so that the upper locking claw 51 descends and disengages from the locking tool 70 when the upper wall 5e of the tank cover 5 is manually pressed from the outside. . The direction in which the upper locking claw 51 and the locking tool 70 are unlocked is perpendicular to the direction in which the tank cover 5 rotates.

  As shown in FIG. 2, the means for holding the tank cover 5 in the open position includes a lateral locking claw 52 protruding rearward from the rear end portion of one side wall of the tank cover 5, and the tank cover 5 is open. Thus, the tank cover 5 is prevented from rotating further outward B by being caught by the side edge of the protrusion hole 16 a of the side cover 16. The margin of the lateral locking claw 52 is set such that an external force is applied to the tank cover 5 or is easily detached from the side edge of the side cover 16 when the tank cover 5 is to be removed from the toilet bowl 10.
