In the seat-type toilet equipped with a washing device shown in FIGS. 3 to 5, 40 is the toilet main body, 41 is a water tank,
Reference numeral 42 indicates a toilet seat, 43 indicates a lid, and an integral drive mechanism in which the electric motor 1, the fan 11, and the pump 21 are assembled together is provided in the machine storage section 44 of the toilet main body 40. The exhaust passage 19 of the fan 11 is connected to the air outlet 45 of the toilet main body, and the heating wire 46 disposed in the exhaust passage 19 is wired to the terminal 8A of the changeover switch 8 in parallel with the winding wire 6A. The airflow formed by the fan 11 is heated and discharged as warm air toward the body of the toilet user. Further, the discharge passage 29 of the pump 21 is communicated with a water storage tank 47 provided in the machine storage section 44, and the water storage tank 47 is provided with a heater 48 having a built-in heating wire to constantly heat the water in the tank 47. When pressurized water is introduced into the tank 47 from below as the rotor 22 of the pump 21 rotates,
A pipe that sends hot water to a cylinder 49 that is open and communicates with the upper part of the tank 47, is slidably inserted into the inner diameter of the cylinder 49, is normally biased by a spring (not shown), and is housed in the cylinder 49. 51
is caused to extend and protrude outwardly against the spring force by the discharge pressure of the pump as shown in FIG. It spews out hot water.

With the above configuration, the electric motor 1 can be installed in the space behind the toilet discharge pipe 52 in the machine storage section 44 of the toilet main body 40, and the electric motor 1 can be installed in the space behind the toilet discharge pipe 52.
An exhaust passage 19, a discharge passage 29, and a water storage tank 4 are installed using spaces on both sides of the discharge pipe 52.
7, the space in the machine storage section 44 can be used effectively, and the storage equipment can be attached with plenty of time.

The effects of the above embodiment are as follows.
First, after a user uses the toilet, when the user presses the mover 8C of the changeover switch 8 provided at an arbitrary position on the toilet main body 40 so as to contact the terminal 8B, the rotation of the electric motor 1 causes its rotating shaft 2 to become a one-way clutch. 20 is connected to the rotating shaft 23 of the pump 21, the rotor 22 is rotated, hot water is sent to the cylinder 49 through the water storage tank 47, the pipe 51 is made to protrude from the cylinder 49 by the discharge pressure water of the pump, and the pipe 51 is caused to protrude from the cylinder 49 through the injection hole 50. It squirts toward the user's anus to cleanse the anus.
At this time, the one-way clutch 10 is in a free state.
Next, when the slider 8C of the changeover switch 8 is pushed so as to contact the terminal 8A, the rotating shaft 2 of the electric motor 1 rotates in the opposite direction, and the one-way clutch 10 rotates the drive shaft 13 of the fan 11. At the same time, the one-way clutch 20 becomes free, so the pump 21 is stopped and hot water is no longer spouted, and the blades 12 of the fan 11 rotate to discharge air from the air outlet 45 to the heating wire 46 through the exhaust passage 19. The device blows warm air around the user's anus to dry it.

The injection of hot water by the rotation of the pump 21 and the injection of hot air by the rotation of the fan 11 are not carried out simultaneously but are carried out selectively.
The rotation of the fan 11 and the pump 21 can be selectively driven by a single reversible rotary electric motor, and the space in the machine storage section of the toilet main body can be effectively utilized.

[Effects of the Invention] In the present invention, a blade of a fan is connected to both ends of the rotating shaft of a reversible rotating electric motor installed in the machine storage part of the toilet main body via a first one-way clutch, and the other end is is connected to the rotor of the pump via a second one-way clutch, and the first and second one-way clutches are connected to one of the one-way clutches in one direction of rotation of the rotating shaft of the electric motor. transmits rotation, but the other one-way clutch is in a free state, and in the other direction of rotation of the rotating shaft of the electric motor, the other one-way clutch transmits rotation, but the one one-way clutch is in a free state. The exhaust passage of the fan is connected to an air outlet attached to the toilet bowl body, and the discharge passage of the pump is connected to a washing water injection pipe of the toilet bowl body,
Rotational drive of the fan or pump is selectively performed by selecting the rotational direction of the reversible rotary motor and operating a changeover switch, and the unselected fan or pump is maintained in a stopped state. When operating the switch to select pump drive, the cleaning water discharged by the pump is sent to the cleaning water injection pipe via the pump's discharge passage and is sprayed from the tip of the pipe, allowing the user to clean the toilet. Moreover, at this time, air is not blown out from the air outlet, and the next time you operate the selector switch to select fan drive, the air discharged into the fan exhaust passage will be directed to the toilet bowl. It is blown out from the attached air outlet,
The flushing water is sprayed onto the flushed area of the toilet user and used to dry the flushed area, and at this time, the flushing water is not sprayed from the flushing water spraying pipe. As described above, according to the present invention, in a toilet bowl equipped with a flushing device, the pump for jetting flushing water from the flushing water jetting pipe and the fan for blowing out drying air from the air spout are combined into a single electric motor. Since it is an assembled integral drive mechanism, the space occupied by the integral drive mechanism in the machine storage section of the toilet body is smaller than when the fan and pump are driven by separate electric motors. Therefore, make effective use of the space in the machine storage area by installing other control equipment, such as installing an electric motor to control the sliding of the cleaning water injection pipe, or by increasing the size and power of fans, pumps, and reversible rotary electric motors. In addition, the installation of the storage machine can be done with plenty of time, which is a great advantage. Further, the integrated drive mechanism allows selective driving of the fan or pump with a single reversible rotary electric motor, and unnecessary driving force is not transmitted to fans or pumps that are not selected during driving. It also has less wear and tear, and can be constructed to be smaller, lighter, and cheaper as a whole with the same performance, and can reduce power consumption in practical use.

Furthermore, in the present invention, the central axis of rotation of the blades of the fan and the central axis of rotation of the rotor of the pump are arranged coaxially with the rotational axis of the electric motor, and the first and second one-way clutches are disposed between them. With this structure, direct rotation transmission via the one-way clutch can be achieved without the need for drive assisting means such as belts or chains. In addition, in the present invention, a cylindrical wall is formed at the end of the rotational drive shaft of the fan blade and the rotational shaft of the pump rotor, and a cylindrical wall is formed inside with a shaft hole centered on the rotational center axis thereof, and the cylindrical wall is disposed at the axial center of the cylindrical wall. By configuring the first and second one-way clutches between the rotary shaft ends of the electric motor, the fan and the pump can be selectively driven by a single electric motor with an extremely simple configuration. Furthermore, by fixing the fan and pump casings to the motor casing, an integrated structure that is extremely compact as a whole can be obtained.
