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

  As shown in FIG. 2, the toilet device 1 of the present example is a variety of devices such as a cleaning water discharge device 11, a local cleaning device 12, and a trap device 13 provided with a detergent supply means 2 with respect to a toilet body 10 constituting the main body. Is a flush toilet apparatus 1 configured by arranging and deploying together.

  The toilet body 10 is a housing that houses the various devices 11 to 13. In this example, the toilet body 10 is made of synthetic resin, and includes a bowl forming part 15 a that forms the bowl portion 15 and an outer shell case that forms the outer shell of the toilet device 1. 16 is formed by welding and integration. A bowl portion 15 that opens to the upper surface is provided in the front region of the toilet body 10. In the rear area of the toilet body 10, an equipment storage portion 17 that is a space surrounded by the bowl forming part 15 a and the outer shell case 16 is formed, and the cleaning water spouting device 11 and the local cleaning device are formed with respect to the equipment storage portion 17. 12 and a trap device 13 are accommodated and arranged.

  Specifically, the outer shell case 16 of the present example includes a pair of left and right rear shell outer shell piece members 16a that form the side surfaces of the rear lower portion of the toilet device 1, a skirt outer shell piece member 16b that covers the outside of the bowl portion 15, and will be described later. A rear shell piece 16c for the rear part of the rising part 20 serving as the rear outer shell of the rising part 20, a pair of left and right rising part pieces 16d for the side part of the rising part 20 and the rear outer shell of the toilet device 1. The rear wall outer shell piece material 16e, the upper surface outer shell piece material 16f forming the front portion of the rising portion 20 and the upper edge portion of the bowl portion 15, is formed. These piece materials 16a to 16f are attached to a metal support frame 14 installed on the floor to form an outer shell of the toilet device 1 having a predetermined shape. The upper edge of the bowl forming part 15a is welded to the lower edge of the upper surface outer shell piece material 16f, but a rim portion 15b provided on the upper edge of the bowl portion 15 is provided at the lower edge of the upper surface outer shell piece material 16f. Is formed. The outer shell case 16 is not limited to the above configuration, and can be formed by combining outer shell piece materials of arbitrary sections.

  The trap device 13 is provided in a lower area of the device storage portion 17 of the toilet body 10. The trap device 13 of this example is a turn trap system that can be expected to save water as shown in FIG. 3, that is, a flexible trap cylinder 19 connected to a drain cylinder 18 projecting rearward from the lower part of the bowl 15. However, it has a structure in which the water 35 in the bowl part 15 can be drained by being rotated up and down by a motor.

  As shown in FIGS. 2 and 3, the washing water discharge device 11 and the local washing device 12 are provided in the upper region of the trap device 13 in the device storage portion 17 of the toilet body 10. Here, the upper part of the rear region of the toilet body 10 is a rising portion 20 that rises above the upper surface level of the front region of the toilet body 10 where the bowl portion 15 is located. It has a structure in which the equipment storage portion 17 for storing the cleaning device 12 can be widely used. 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. A local cleaning device for injecting local cleaning water at the lower edge of the front portion of the rising portion 20 facing the rear portion of the opening edge of the bowl portion 15 toward the local portion of the user after the stool at the center in the left-right direction 12 washing nozzles 12a are provided so as to be extendable and retracted, and at one end in the left-right direction, there is provided a washing water discharge port 23 of the washing water discharge device 11 for flowing the bowl washing water after the stool.

  As shown in FIG. 3, 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, which is a water source, to the bowl portion 15. A structure is adopted 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 washing water opening / closing valve 25 arranged in the passage 24. In the case of the tankless system, the tap water can be used as it is as the conveying pressure of the bowl washing water, or the bowl washing water can be pumped by providing a pump in the washing water passage 24. The opening / closing operation of the cleaning water opening / closing valve 25 of the cleaning water spouting device 11 and the turning operation of the trap cylinder 19 of the trap device 13 are controlled by a control unit (see FIG. (Not shown). As described above, the cleaning water discharge port 23 is provided on one side in the width direction at the rear end of the opening edge of the bowl portion 15, so that the discharged bowl cleaning water passes through the bowl portion 15 as indicated by the arrow in FIG. 2. It becomes a swirl flow that swirls vigorously and is configured so that the filth in the bowl portion 15 can flow at once.

  More specifically, in the cleaning water spouting device 11 of this example, as shown in FIG. 4, fine air bubbles are mixed into the bowl cleaning water, and the air is refined to generate fine bubbles to be contained in the bowl cleaning water. A 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. 5, the fine bubble generating means 27 is constituted by a tube material 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. . The aeration unit 28 is formed by connecting an air supply pipe 31 having a check valve 30 around the nozzle portion 28a with a reduced diameter of the washing water flow path 24, and the air is washed in the bowl by the negative pressure generated in the nozzle portion 28a. It can be mixed in water without any problem. 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.

  As shown in FIGS. 3 to 5, the detergent supply means 2 includes a detergent supply path 8 extending from the detergent tank 3 to the detergent mixing section 7 provided in the cleaning water flow path 24, and a detergent provided in the detergent supply path 8. When the detergent pump 36 is driven and the detergent opening / closing valve 37 provided in the detergent supply path 8 is opened, the detergent mixing unit 7 removes liquid neutral detergent stored in the detergent tank 3 with respect to the bowl washing water. The detergent is mixed to produce detergent mixture water. 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. In the toilet device 1 of this example, in order to facilitate maintenance work such as detergent replenishment to the detergent tank 3, a device for easily detachably attaching the detergent tank 3 to the toilet device 1 is provided. This will be described in detail below.

  That is, as shown in FIG. 1, a tank storage space 4 for storing the detergent tank 3 and connecting to the detergent supply path 8 is provided in the outer shell case 16 of the toilet device 1, and this tank storage space 4 is provided in the outer shell case 16. A cover body 6 is provided which communicates with a maintenance opening 5 provided in the upper portion of the rear portion and opens and closes the maintenance opening 5. The upper part of the rear portion of the toilet device 1 where the maintenance opening 5 with which the tank storage space 4 communicates is located is a so-called rising portion 20 that is not a seating portion, and faces the open space A that extends above the toilet device 1. (FIG. 3). Therefore, in the toilet apparatus 1 of this example, the detergent tank 3 can be easily attached to and detached from the tank storage space 4 through the maintenance opening 5 using the opened space A. This makes maintenance work easier.

  Specifically, the tank storage space 4 is provided at one end of the rising portion 20 in the left-right direction. The maintenance opening 5 includes an upper surface opening portion 40 that opens to the upper surface 20a and a side surface that opens to the side surface 20b in the portion of the outer shell case 16 that forms the rising portion 20 (specifically, the outer shell piece material 16c for the rising portion rear portion). The opening 41 is continuously drilled. That is, the tank storage space 4 is formed in a concave space that opens upward and laterally from the rising portion 20 through the maintenance opening 5 and is recessed inward from the upper surface 20a and the side surface 20b of the rising portion 20. .

  The tank storage space 4 is formed so as to be surrounded by a partition wall 9 that is watertightly isolated from other internal parts of the rising portion 20. The partition wall 9 includes a lower wall portion 42 constituting the lower bottom surface of the tank storage space 4, an inner wall portion 43 constituting the inner bottom surface of the tank storage space 4, a front wall portion 44 constituting the front and rear surfaces of the tank storage space 4, And a rear wall portion 45. A connecting end 8 a of the detergent supply path 8 on the toilet body 10 side is disposed on the inner wall portion 43 so as to face the tank storage space 4. The partition wall 9 is attached to the connecting end 8a of the detergent supply path 8 and the outer shell case 16 constituting the rising portion 20 via a packing (not shown), so that the rising portion 20 of the tank storage space 4 is provided. Water-tightness is ensured. According to this, even if liquid leakage of the detergent tank 3 occurs in the tank storage space 4 in the outer shell case 16, the detergent leaked by the partition wall 9 is applied to various devices arranged in other internal parts of the toilet device 1. Therefore, the occurrence of a malfunction such as a short circuit of the toilet device 1 is prevented.

  The cover body 6 is formed in an inverted L-shaped longitudinal section with an upper surface plate portion 60 that closes the upper surface opening portion 40 of the maintenance opening 5 and a side surface plate portion 61 that closes the side surface opening portion 41 of the maintenance opening 5. ing. A shaft portion 62 that is pivotally supported by a bearing portion 46 provided at the lower edge of the side opening 41 of the maintenance opening 5 is formed at the lower end of the side plate 61. This cover body 6 holds the detergent tank 3 between the upper surface plate portion 60 and the side surface plate portion 61. The detergent tank 3 is a substantially rectangular parallelepiped container, and a connection joint 3 a to be connected to the connection end 8 a of the detergent supply path 8 and a detergent inlet 3 b are provided on the upper surface portion thereof. A pair of elastically deformable tank gripping pieces 63 project inwardly from the side plate portion 61 of the cover body 6, and the detergent tank 3 has a pair of tank gripping pieces with its lower end placed on the shaft portion 62. It is detachably held by the cover body 6 so as to be held at 63.

  The cover body 6 is attached to the side surface 20b of the rising portion 20 so as to be freely rotatable up and down by the shaft support structure of the shaft portion 62 and the bearing portion 46, and the maintenance opening 5 is maintained even when the detergent tank 3 is held. It can be opened and closed. Specifically, when the cover body 6 is turned upward, the maintenance opening 5 is closed by the cover body 6. At this time, the held detergent tank 3 is in a tank deployment position where it can be accommodated in the tank storage space 4, and at this time, the connection joint 3 a of the detergent tank 3 is automatically connected to the connection end 8 a of the detergent supply path 8. ing.

  In the state where the maintenance opening 5 is closed by the cover body 6, the outer surfaces of the upper surface plate portion 60 and the side surface plate portion 61 of the cover body 6 are the upper surface 20 a of the outer shell case 16 that forms the rising portion 20 and A continuous surface that is substantially flush with the side surface 20 b is formed, and a clean and good appearance appears on the toilet device 1. In addition, a finger hook recess 64 is formed on the outer surface of the upper surface plate portion 60 of the cover body 6 of this example, so that the finger can be easily caught when the cover body 6 is rotated, and the operability is improved. It is illustrated. In addition, the inner surface of the upper surface plate portion 60 of the cover body 6 and the edge of the upper surface opening portion 40 of the maintenance opening 5 are appropriately clicked when the maintenance opening 5 is closed by the cover body 6. The concave / convex fitting portion 47 is formed so as to provide an operational feeling when the cover body 6 is closed to the maintenance opening 5 and to hold the closed posture.

  On the other hand, when the cover body 6 is rotated downward, the cover body 6 protrudes to the side of the rising portion 20 and the maintenance opening 5 is opened. In this example, the cover body 6 is configured to be pivotable downward to such an extent that the side surface plate portion 61 becomes substantially horizontal. When the cover body 6 is pivoted downward in this manner, the detergent tank 3 held by the cover body 6 is also pulled out of the outer shell case 16 together with the cover body 6. The detergent tank 3 in a state of being drawn out of the outer shell case 16 is pulled out upward from between the tank gripping pieces 63 using the open space A that extends above the toilet device 1 and covers the cover body. 6 can be easily removed. Of course, the detergent tank 3 can also be easily inserted between the tank gripping pieces 63 of the cover body 6 pivoted downward using the open space A extending above the toilet device 1. That is, the cover body 6 pivoted downward is a tank attaching / detaching position, and the detergent tank 3 is drawn out of the toilet device 1 (outside the outer shell case 16) at the tank attaching / detaching position. Thus, the detergent tank 3 can be easily attached to and detached from the cover body 6 by using the open space A extending above the toilet device 1, and the maintenance work such as the supplement of the detergent to the detergent tank 3 can be facilitated. It is shown.

  In addition, the side plate 61 of the cover body 6 of this example is provided with a window hole-shaped remaining amount display section 50 for visually confirming the remaining amount of detergent in the detergent tank 3 held in the cover body 6. According to this, the remaining amount display part 50 appearing in the open space A that spreads above the toilet device 1 makes it easy to visually recognize the remaining amount of the detergent in the detergent tank 3 that is deployed in the toilet device 1. 3 makes it possible to easily determine the timing of maintenance work such as replenishing detergent. Here, an illumination device such as an LED may be disposed in the tank storage space 4. According to this, the visibility of the remaining amount of the detergent tank 3 can be improved. Furthermore, it is preferable to form the detergent tank 3 with a light-transmitting material because it can reveal the shadow of the presence or absence of the detergent and can be expected to further improve the visibility.

  More specifically, in this example, the connection joint 3 a is provided so as to project substantially horizontally inward on the upper surface of the detergent tank 3, and the connection end 8 a of the detergent supply path 8 is substantially at the vertical wall-shaped inner wall 43 of the partition wall 9. The connecting joint 3a and the connecting end 8a of the detergent supply path 8 are provided so as to face outward in the horizontal direction.
