A drying device B is provided which includes a built-in blower 8 and an electric heater 9 including a motor 7 for driving the drying device B. Then, by energizing the electric heater 9 and operating the blower 8, an air flow is formed from the air supply port 3 to the discharge port 2, and after being heated by the electric heater 9, it is discharged from the discharge port 2 into the toilet bowl 1. It was used to dry local areas. For deodorizing when using the toilet, the structure is similar to that of the drying device B, with a deodorizing agent instead of the electric heater 9, and air flowing in the opposite direction to that of the drying device B.
That is, a deodorizing device configured to discharge the air inside the toilet bowl 1 to the outside of the toilet bowl 1 has been used either alone or in combination with a drying device.

Problems to be Solved by the Invention However, while the above configuration has the advantage of being able to use the drying device B and the deodorizing device independently, it is difficult to use two devices with the same configuration as a device that has both functions.

Each impeller is arranged so that airflow flows into the impeller, and the centrifugal blower is configured to be driven by a single electric motor that can rotate in forward and reverse directions.The deodorizer opens into the toilet bowl on the upstream side of the centrifugal blower. A deodorizing intake passage provided with a deodorizing intake port, and a drying intake passage provided with a drying intake port that opens to the outside of the toilet via a damper that is opened and closed by the pressure difference in the ventilation passage caused by the centrifugal blower. A drying outlet opening into the toilet bowl is provided on the downstream side of the type blower via an electric heater.

Effects The present invention can provide a small toilet seat device with the above-described configuration by using a single blower to provide both drying and deodorizing functions, and by changing the rotation direction of the electric motor. , the discharge port can be selected and the damper can be opened and closed.

EXAMPLE Hereinafter, an example of the present invention will be explained using the first factor and FIG.

FIG. 1 shows a case in which the damper 26 of the device A is opened to perform local drying and deodorizing functions at the same time, and FIG. 2 shows a case in which the damper 26 is closed to perform the deodorizing function. In FIGS. 1 and 2, solid line arrows indicate the flow of local drying air, and dashed-dotted line arrows indicate the flow of deodorizing air.

Further, the drying outlet 30 is provided with an opening/closing flap 32 that automatically opens and closes depending on the pressure of the air flow passing therethrough and its own weight. On the other hand, a fill spring 33 is arranged on the damper 26 to rotate it in the direction of the dry air intake passage 28.

Further, the centrifugal blower 35 has two centrifugal impellers 36, 37 whose blades 36a, 37a have different arc directions with respect to the same suction direction, and also have different blowing capacities. Casing 38 corresponding to the arc direction.

The impellers are arranged such that air flows from the centrifugal impeller 36 on the upstream side to the centrifugal impeller 37 on the downstream side via the axial flow impeller 40.

On the other hand, the discharge sides of the casings 38 and 39 are provided with a drying outlet 3o and a deodorizing outlet 31, respectively, and inside the centrifugal blower 35 is an act rotor type electric motor 41, such as a transistor motor, which can rotate in forward and reverse directions.
are arranged so that the impellers 36, 37 and 4o rotate at the same time about the same rotation axis. In addition, axial flow type impeller 4
A baffle plate 42 protrudes in the direction of the axial flow impeller 40 from the casing 38, 39 facing the outer periphery of the axial flow impeller 4.
A gap 43 is provided between the outer periphery of 0 and the outer periphery of 0.

Further, in FIGS. 1 and 2, 44 indicates an intake port of the centrifugal blower 35, and 34 indicates the exterior of the toilet seat device A. Further, solid arrows indicate the flow of drying air, and dashed arrows indicate the flow of deodorizing air. In addition, coil spring 3
3 is set to such a strength that the damper 26 rotates about the rotation shaft 25 due to the magnitude of the negative pressure within the ventilation passage 45 generated by the rotation of the centrifugal blower 35. That is, in this embodiment, the air blowing capacity of the upstream centrifugal impeller 36 is set to be higher than that of the downstream centrifugal impeller 37, so that the upstream centrifugal impeller 36 rotates in the normal direction. The strength of the coil spring 33 is set to be weaker than the negative pressure in the ventilation passage 45 caused by the rotation of the downstream centrifugal impeller 37 in the normal direction. is set strongly.

Next, a case where local drying operation and deodorizing operation are performed simultaneously will be explained using FIG. Upstream centrifugal impeller 3

Ru. On the other hand, since the deodorizing intake port 23 is always open even when the drying path 28 is open, a small amount of air is sucked into the centrifugal blower 35 via the deodorizing agent 22. That is, in this case, a part of the deodorizing function can be obtained even during drying. Further, the opening/closing flap 32 provided at the drying outlet 30 is pushed upward by the airflow passing through the drying outlet 30.

Next, the case of performing deodorizing operation will be explained using FIG. 2. The centrifugal impeller 3 on the downstream side by reversing the electric motor 41

By closing, the toilet bowl 2 is removed from the deodorizing intake port 23.
1 is sucked into the deodorizing path 24, passes through the deodorizing agent 22, and the deodorized air flow is sent to the upstream centrifugal impeller 36, the axial impeller 40, and the downstream centrifugal impeller 36. car 3
7 and is discharged to the outside of the toilet bowl 21 from the deodorizing outlet 31.

In this case, a small amount of air is suddenly sucked into the interior from the upper drying outlet 30, but the opening/closing flap 31 provided at the drying outlet 30 is moved downward by its own weight, and the drying outlet 30 to prevent a flow flowing back into the drying outlet 30.

According to this configuration, by rotating the upstream centrifugal impeller 36 in the normal direction, a negative pressure stronger than the strength of the coil 33 is generated in the ventilation path 45, and the damper 2
6 and the drying inlet 27, the centrifugal blower 3 is removed from the drying inlet 27 and the deodorizing inlet 23.
