It is.

2. Description of the Related Art Conventionally, in this type of device, as shown in FIG. A drying device B constitutes a ventilation path 5 that communicates with an air supply port 8, and has a built-in blower 8 consisting of an impeller 6 and a motor 7 for driving the impeller 6 in the ventilation path 5, and an electric heater 9. Then, by energizing the electric heater 9 and operating the blower 8, an air flow from the air supply port 3 to the discharge port 2 is formed. In addition, for deodorizing when using the toilet, it has a similar configuration to the drying bag f2B, but a deodorizing agent is placed in place of the electric heater 9, and it is the opposite of the drying bag f2B. A deodorizing device configured to flow air in the direction of , that is, 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. This poses a problem in that the entire device becomes large in size.

Each impeller is arranged so that airflow flows from the upstream centrifugal impeller to the downstream centrifugal impeller via the axial flow impeller, and a single electric motor capable of forward and reverse rotation is used. A deodorizing and drying air intake path is provided on the upstream side of the centrifugal blower which is configured to be driven, and has a deodorizing and drying intake port that opens into the toilet bowl through a deodorizing agent, and a deodorizing and drying air intake path is provided on the downstream side of the centrifugal blower, which is opened outside the toilet bowl. The toilet is equipped with a deodorizing outlet and a drying outlet that opens into the toilet bowl 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.

EXAMPLE Hereinafter, an example of the present invention will be explained using FIGS. 1 and 2.

Figure 1 shows the case where the centrifugal impeller on the upstream side of this device A is rotated normally to perform local drying and deodorizing functions at the same time, and Figure 2 shows the case where the centrifugal impeller on the downstream side is rotated normally to perform the deodorizing effect. The case where this is done is shown below. In addition, in FIGS. 1 and 2, solid line arrows indicate the flow of air for local drying,
The dashed-dotted line arrow indicates the flow of deodorizing air.

As shown in FIGS. 1 and 2, the toilet seat device A of the present invention has an opening in the toilet bowl 21 via a deodorizing agent 22 on the upstream side of a centrifugal blower 35 that supplies air for local drying and deodorization. A deodorizing and drying air intake passage 24 is provided with a deodorizing and drying air intake 23 that is provided with a deodorizing and drying air inlet 23, and on the downstream side of the centrifugal blower 35, there is a deodorizing and drying outlet 31 that opens to the outside of the toilet +a 21 and an electric heater 29 that opens into the toilet bowl 21. A drying discharge port 30 is provided.

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.

Further, the centrifugal blower 35 has two centrifugal impellers 36 and 37, each of which has a different arc direction A36a, 37a with respect to the same suction direction.
, 37, the casing 38 corresponds to each arc direction of the casing 38,
39, and an axial impeller 4 corresponding to the arc direction of the blade 37a.
0, an axial flow impeller 40 is arranged between the upstream centrifugal impeller 36 and the downstream centrifugal impeller 37, and the axial flow impeller 40 is disposed between the upstream centrifugal impeller 36 and the downstream centrifugal impeller 37. impeller 40
Each impeller is arranged so that airflow flows into the centrifugal impeller 37 on the downstream side through the centrifugal impeller 37. On the other hand, the discharge sides of the casings 38 and 39 are provided with a drying discharge port 30 and a deodorizing discharge port 31, respectively, and inside the centrifugal blower 35 is an electric motor 28, which is an out rotor type and is capable of forward and reverse rotation, such as a transistor motor. are arranged so that the impellers 36, 37 and 4o rotate at the same time about the same rotation axis. Further, a rectifying plate 25 is provided by protruding from the casings 38 and 39 facing the outer periphery of the axial flow impeller 40 in the direction of the axial flow impeller 4o, with a gap 26 between the casings 38 and 39 facing the outer periphery of the axial flow impeller 40. It is set up.

Further, in FIGS. 1 and 2, 27 indicates an intake port of the centrifugal blower 35, and 34 indicates the exterior of the toilet seat device A.

Next, the case where local drying operation and deodorizing operation are performed at the same time will be explained using Figure @1. Upstream centrifugal impeller 3
Electric motor 2 that can be rotated forward or reverse so that 6 is in the normal rotation direction
8, the air inside the toilet bowl 21 is sucked into the deodorizing and drying air intake path 24 through the deodorizing and drying intake port 23, and is sent to the electric heater 29 through the centrifugal impeller 36 on the upstream side of the centrifugal blower 35. The airflow, which is heated here and becomes warm air, is discharged into the toilet bowl 21 through the drying discharge port 30 and used for drying the private parts. On the other hand, the deodorizing dry intake passage 24
When passing through the deodorizer 22 placed inside, it receives a deodorizing effect. Further, the opening/closing flap 32 provided at the drying outlet 30 is pushed upward by the air flow passing through the drying outlet 30.

Next, the case of performing deodorizing operation will be explained using FIG. 2. Downstream centrifugal impeller 37 and axial flow impeller 4
Electric motor 4 capable of forward and reverse rotation so that 0 is the normal rotation direction
1, the air inside the toilet bowl 21 is sucked into the deodorizing and drying intake passage 24 through the deodorizing and drying intake port 23, passes through the deodorizing agent 22, and the airflow that has been deodorized is transferred to the upstream side. The toilet bowl 21 is discharged from the deodorizing outlet 31 via the centrifugal impeller 36, the axial flow impeller 40, and the downstream centrifugal impeller 37.
It is discharged outside. In this case, a small amount of air is 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 In order to close the drying outlet 30, a flow flowing back into the inside of the drying outlet 30 is prevented.

According to this configuration, by rotating the electric motor 28 in the normal direction, an air flow is generated that flows from the deodorizing and drying inlet 23 to the drying outlet 30 via the centrifugal blower 35, and can be used for drying and deodorizing the private parts at the same time. On the other hand, by reversing the electric motor 28, airflow is generated that flows from the deodorizing and drying inlet 23 through the centrifugal blower a5 and the axial impeller 40 to the deodorizing outlet 31, and can be used only for deodorizing operation.

On the other hand, the axial flow type impeller 40 is connected to the casings 38 and 39 so as to have a gap 26 between the axial flow type impeller 40 and the outer circumference of the axial flow type impeller 40.
Providing the straightening plate 25 projecting in the direction has the effect of preventing flow disturbances caused by mutual interference between the two impellers 36 and 37 around the outer periphery of the axial impeller 40.

Effects of the Invention As described above, according to the present invention, the discharge direction from the centrifugal blower can be changed by changing only the rotational direction of the drive motor, and deodorization and drying can be performed freely. Therefore, the configuration of the centrifugal blower can be simplified, and at the same time, the configuration of the toilet seat device can be downsized.
