And a power supply unit 23 for supplying power to the pump 30.

  The washing tank 21 is installed behind the toilet body 10. For this reason, the flush toilet bowl can realize a low silhouette. The cleaning tank 21 has an upstream end of the water supply path 22 connected to the lower part of the side surface. The water supply path 22 connects the downstream end to the rear part of the toilet bowl 11 of the toilet body 10. The wash water discharged from the downstream end of the water supply channel 22 flows down to the surface of the toilet bowl 11 while flowing in one direction along the rim water passage provided on the upper peripheral edge of the toilet bowl 11. For this reason, the wash water forms a swirl flow that flows into the toilet drainage channel 12 while swirling the surface of the toilet bowl 11.

  As illustrated in FIG. 2, the pump 30 includes an impeller 31 and a drive unit 36 that rotates the impeller 31. The impeller 31 is rotatably disposed in a pump chamber 32 through which cleaning water flows. The pump chamber 32 has a suction port 33 opened in the side wall portion 32A. The suction port 33 communicates with the cleaning tank 21 through the water supply path 22. In the pump chamber 32, a water supply port 34 is opened in the upper wall portion 32B. The water supply port 34 communicates with the toilet bowl 11 of the toilet body 10 through the water supply path 22.

  The impeller 31 has a rotating shaft 31A that rotates integrally. The rotating shaft 31A extends in the horizontal direction. For this reason, the impeller 31 rotates on a vertical plane. The rotating shaft 31 </ b> A protrudes outward in a watertight manner from the side wall portion 32 </ b> C of the pump chamber 32 facing the suction port 33. The rotating shaft 31 </ b> A has a columnar enlarged portion 31 </ b> B at a portion protruding outward from the pump chamber 32. The rotating shaft 31A is provided with a rotor 37 made of a first permanent magnet on the peripheral surface of the enlarged diameter portion 31B. The rotor 37 is housed in a rotor chamber 38 provided integrally with the side wall portion 32C of the pump chamber 32 so as to be rotatable about the rotation shaft 31A. The rotor chamber 38 extends from the side wall portion 32C of the pump chamber 32, closes the cylindrical peripheral wall portion 38A having a slight gap with the outer peripheral surface of the rotor 37, and the end portion of the peripheral wall portion 38A, and ends the rotating shaft 31A. And a disk-shaped side wall portion 38C provided with a bearing 38B for pivotally supporting the portion at the center of the inner surface.

  The drive unit 36 includes a rotor 37 and a stator 41 made of a coil disposed at a position separated along the circumferential surface of the rotor 37. The stator 41 is fixed to the inner peripheral surface of the electric drive member 40 that is an exchange member. The electric drive member 40 has a cylindrical peripheral wall portion 40A and a side wall portion 40B that closes one end of the peripheral wall portion 40A. A stator 41 is fixed to the inner surface of the end portion on the opening side of the peripheral wall 40A. The electric drive member 40 can be detachably attached to the side wall portion 32 </ b> C of the pump chamber 32 by inserting the rotor chamber 38 inside the stator 41. The drive unit 36 can cause the rotor 37 and the impeller 31 to rotate in a set direction by generating an electromagnetic interaction with the rotor 37 by passing an electric current through the stator 41. For this reason, the washing water sucked from the suction port 33 of the pump chamber 32 by the impeller 31 can be fed from the water feeding port 34. That is, the cleaning water stored in the cleaning tank 21 can be supplied to the toilet body 10.

  As shown in FIGS. 3 and 4, the pump 30 can detachably attach a manual drive member 50 as an exchange member to the side wall portion 32 </ b> C of the pump chamber 32 from which the electric drive member 40 is removed.

  The manual drive member 50 includes a rotating body 51 and a rotation driving section 55 that rotates while holding the rotating body 51 at the tip. The rotating body 51 includes a recess 52 that is open at one end and accommodates the rotor chamber 38, and a second permanent magnet 53 disposed around the recess 52. In a state where the rotor chamber 38 is housed in the recess 52, the second permanent magnet 53 is disposed at a position separated along the circumferential surface of the rotor 37.

  The rotation drive unit 55 includes a drive shaft 56 connected to the rotation center of the rotating body 51, a plurality of gears 57A, 57B, and 57C, a handle 58 that rotates the gear 57C, and a display unit 59 that displays the number of rotations of the handle 58. And have. The rotation drive part 55 can rotate in the direction which set the drive shaft 56 and the rotary body 51 indirectly via several gearwheel 57A, 57B, 57C by rotating the handle | steering-wheel 58 to one direction. When the rotating body 51 rotates in the set direction, the rotor 37 attracted by the magnetic force between the second permanent magnet 53 and the rotor 37 also rotates in the set direction, and the impeller 31 also rotates in the set direction. As a result, the cleaning water sucked by the impeller 31 from the suction port 33 of the pump chamber 32 can be fed from the water feed port 34. That is, the cleaning water stored in the cleaning tank 21 can be supplied to the toilet body 10.

  The display unit 59 counts the number of rotations of the handle 58 when the magnet 58A embedded in the handle 58 is detected by the sensor 59A provided on the rotation path, and can display the number of rotations.

  In the toilet bowl cleaning device 20 having such a configuration, the electric drive member 40 is attached to the drive unit 36 of the pump 30 when there is no power failure, and an electric current flows through the stator 41 and electromagnetic interaction with the rotor 37 occurs. And the rotor 37 is rotated. Thereby, the impeller 31 rotates and the wash water stored in the wash tank 21 can be supplied to the toilet body 10. At this time, the number of rotations or the rotation speed of the rotor 37 and the impeller 31 can be changed by changing the time or intensity of the current flowing through the stator 41. For this reason, the toilet bowl washing | cleaning apparatus 20 can perform the big washing | cleaning with a large amount of washing water, and the small washing with a little amount of washing water by controlling the electric current sent through the stator 41.

  Moreover, this toilet bowl washing | cleaning apparatus 20 removes the electric drive member 40 attached to the drive part 36 of the pump 30, and attaches the manual drive member 50 at the time of a power failure. Then, by rotating the handle 58 in one direction, the rotating body 51 provided with the second permanent magnet 53 is rotated in the set direction. Then, the rotor 37 attracted by the magnetic force between the second permanent magnet 53 and the rotor 37 also rotates in the set direction. As a result, the impeller 31 rotates in the set direction, and the wash water stored in the wash tank 21 can be supplied to the toilet body 10. Thus, this toilet bowl washing | cleaning apparatus 20 can switch the pump 30 which sends the washing water stored in the washing tank 21 to the toilet bowl main body 10 electrically or manually.

  In addition, the toilet cleaning device 20 can determine the amount of cleaning water supplied to the toilet body 10 by determining the number of rotations of the rotor 37 and the impeller 31 according to the number of rotations of the handle 58 of the manual drive member 40. . For this reason, the number of rotations of the handle 58 is set according to the amount of washing water used for the large washing and the small washing, and the handle 58 is set the number of times while checking the number of revolutions displayed on the display unit 59, By rotating, the toilet bowl cleaning device 20 can execute a large washing with a large amount of washing water and a small washing with a small amount of washing water even manually.

  Therefore, the flush toilet equipped with the toilet cleaning device 20 of the first embodiment can perform toilet cleaning during a power failure.

<Example 2>
As shown in FIGS. 5 and 6, the flush toilet of the second embodiment is different from the first embodiment in the configuration of the manual drive member 60. Other configurations are the same as those of the first embodiment, and the same configurations are denoted by the same reference numerals and detailed description thereof is omitted.

  The manual drive member 60 according to the second embodiment includes a rotating body 51 and a rotation driving unit 61 that rotates while holding the rotating body 51 at the tip. The rotation drive unit 61 includes a drive shaft 62 connected to the rotation center of the rotating body 51, a spiral spring 63 that is an elastic body having an inner end connected to the drive shaft 62, a handle 58 connected to the drive shaft 62, a handle And a display unit 59 for displaying the number of rotations of 58. The rotation drive unit 61 can wind up the spiral spring 63 by rotating the handle 58 clockwise. The rotation drive unit 61 has a lock mechanism (not shown) that locks the spiral spring 63 in a state where the spiral spring 63 is wound up. By releasing the lock mechanism, the drive shaft 62 rotates counterclockwise by the elastic force of the spiral spring 63. The drive shaft 62 has a clutch function (not shown), and the front end side of the drive shaft 62 connected to the rotating body 51 does not rotate right but rotates only counterclockwise. For this reason, when the spiral spring 63 is wound up by the handle 58, the rotating body 51 does not rotate, and when the lock mechanism is released, the rotating body 51 rotates left together with the drive shaft 62. Thus, the handle 58 can indirectly rotate the rotating body 51.

  When the rotating body 51 rotates counterclockwise, the rotor 37 attracted by the magnetic force also rotates counterclockwise, and the impeller 31 also rotates counterclockwise. As a result, the cleaning water sucked by the impeller 31 from the suction port 33 of the pump chamber 32 can be fed from the water feed port 34. That is, the cleaning water stored in the cleaning tank 21 can be supplied to the toilet body 10.

  The toilet bowl cleaning device 70 having such a configuration removes the electric drive member 40 attached to the drive unit 36 of the pump 80 and attaches the manual drive member 60 during a power failure. Then, after rotating the handle 58 clockwise to wind up the spiral spring 63, when the lock mechanism is released, the rotating body 51 rotates counterclockwise by the elastic force of the spiral spring 63. Then, the rotor 37 attracted by the magnetic force between the second permanent magnet 53 and the rotor 37 rotates counterclockwise. Thereby, the impeller 31 rotates counterclockwise, and the wash water stored in the wash tank 21 can be supplied to the toilet body 10. Thus, this toilet bowl washing | cleaning apparatus 70 can switch the pump 80 which sends the washing water stored in the washing tank 21 to the toilet bowl main body 10 electrically or manually.

  Moreover, since this toilet bowl washing | cleaning apparatus 70 rotates the rotary body 51 with the elastic force of the spiral spring 63, it can rotate the rotary body 51 stably. For this reason, the impeller 31 rotates stably, and the toilet bowl washing | cleaning apparatus 70 can supply the flush water of the set amount of water to the toilet bowl main body 10 reliably at the time of a power failure.

  Further, in the toilet bowl cleaning device 70, since the degree of winding of the spiral spring 63 is determined by the rotation speed of the handle 58, the rotation speeds of the rotor 37 and the impeller 31 are determined by the rotation speed of the handle 58 and supplied to the toilet body 10. The amount of wash water can be determined. For this reason, the number of rotations of the handle 58 is set according to the amount of washing water used for the large washing and the small washing, and the handle 58 is set the number of times while checking the number of revolutions displayed on the display unit 59, By rotating, the toilet bowl cleaning device 70 can execute a large washing with a large amount of washing water and a small washing with a small amount of washing water even manually.

  Therefore, the flush toilet equipped with the toilet cleaning device 70 of Example 2 can also perform toilet cleaning at the time of a power failure.
