Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a toilet seat device used in Western-style toilets, etc., which has the function of washing the private parts with hot water etc. after defecating, and then drying with warm air, and the function of deodorizing odors. It is something.

2. Description of the Related Art Conventionally, in this type of device, as shown in FIG. A drying device B is provided, which constitutes a ventilation passage 5 that communicates with the cutout 3, and has a built-in blower 8 and an electric heater 9, which are composed of an impeller 6 and a motor 7 that drives the impeller 6, in the ventilation passage 5. It was set up. 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 placed in place of the electric heater 9, and the air flow in the opposite direction to that of the toilet bowl 1. A deodorizing device configured to discharge the air inside the toilet bowl 1 outside 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 arrange two devices with the same configuration as a device that has both functions. However, there was a problem in that the entire device became larger.

The present invention solves these conventional problems, and aims to provide a toilet seat device that has both drying and deodorizing functions with a single blower and is miniaturized.

Means for Solving the Problems The present invention provides two centrifugal impellers whose blades have different arc directions with respect to the same suction direction and have different blowing capacities, and their respective casings. [Each impeller is arranged so that airflow flows into the impeller through the inside of the centrifugal impeller on the upstream side, and is configured to be driven by a single electric motor capable of forward and reverse rotation. A deodorizing intake path is provided on the upstream side of the centrifugal blower with a deodorizing inlet that opens into the toilet bowl through a deodorizing agent, and a damper that is opened and closed by the pressure difference in the ventilation path created by the far U-shaped blower is used to supply air outside the toilet bowl. a dry air intake path with a dry air intake opening opening to the dry air intake passage;
A drying outlet opening into the toilet bowl via an LD electric heater and a deodorizing outlet opening outside the toilet bowl are provided on the downstream side of the centrifugal blower.

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 FIGS. 1 and 2.

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.

As shown in FIGS. 1 and 2, the toilet seat device A of the present invention includes a deodorizer 22 made of, for example, activated carbon molded into a honeycomb shape, on the upstream side of a centrifugal blower 35 that blows air for local drying and deodorization. A deodorizing intake port 2 that opens into the toilet bowl 21 through the
A centrifugal blower is provided with a deodorizing intake passage 24 having a deodorizing intake passage 24 provided with a drying intake port 27 which opens to the outside of the toilet bowl 21 via a damper 26 that rotates around a rotating shaft 25. A drying outlet 30 opened into the toilet bowl 21 and a deodorizing outlet 31 opened outside the toilet bowl 21 are provided on the downstream side of the toilet bowl 21 via, for example, a coil-shaped electric heater 29. Further, at the drying outlet 3°, an opening/closing lamp 32 is provided which automatically opens and closes due to the pressure of the air flow passing therethrough and its own weight. On the other hand, a coil spring 33 is arranged in 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 have different blowing capacities. Casing 38 corresponding to the circular arc direction.
39, and is arranged so that air flows into the downstream centrifugal impeller 37 via the upstream centrifugal impeller 36, and both impellers 36 and 37 are provided with vents 40. They are connected by a connecting plate 41, and both impellers 36 and 37 are rotated at the same time.

In the configuration shown in FIGS. 1 and 2, the air blowing capacity of the centrifugal impeller 37 on the downstream side is set to be smaller than that of the centrifugal impeller 36 on the upstream side. On the other hand, the discharge sides of the casings 38 and 39 have drying discharge ports 30, respectively.
and a deodorizing outlet 31, and an out rotor type electric motor 42, such as a transistor motor, capable of forward and reverse rotation is disposed inside the centrifugal blower 35, so that both impellers 36 and 37 are rotated on the same rotation axis. It says to rotate.

Furthermore, a casing 38.3 facing the outer periphery of the coupling plate 41
9 protrudes in the direction of the coupling plate 41 and connects the rectifying plate 44 to the coupling plate 4.
1 with a gap 45 between them and the outer periphery of the first plate.

Further, in FIGS. 1 and 2, numeral 43 indicates an intake port of the centrifugal blower 35, and numeral 34 indicates the exterior of the toilet seat device A.

Note that the coil spring a3 is set to have a strength that causes the damper 26 to rotate about the rotation shaft 25 depending on the magnitude of the negative pressure in the ventilation passage 46 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 made larger than the air blowing capacity of the downstream centrifugal impeller 37, so that the upstream centrifugal impeller 36 moves in the normal direction. The strength of the coil spring 33 is set to be weaker than the negative pressure in the ventilation passage 46 caused by rotation, and the strength of the coil spring 33 is set to be weaker than the negative pressure in the ventilation passage 46 caused by the rotation of the downstream centrifugal impeller 37 in the normal direction. The strength is set to strong.

Next, using FIG. 1, a case where local drying and deodorizing operations are performed simultaneously will be explained. Upstream centrifugal impeller 3
6 in the normal direction to make the negative pressure in the ventilation passage 46 stronger than the strength of the coil spring 33.
6 to the ventilation path 46 side to open the drying path 28 through the drying intake port 27, and to open the downstream path 4 of the deodorizer 22.
3 and the air intake port 46 of the centrifugal blower 35, and by operating the centrifugal blower 35, the drying air intake port 2
7, the air outside the toilet bowl 21 is sucked into the exterior casing 34 and flows to the electric heater 29 via the centrifugal impeller 36 on the upstream side of the centrifugal blower 35, where the air is heated and becomes warm air. The flow is discharged into the toilet bowl 21 through the drying outlet 30 and is used for drying the private parts. 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 air flow passing through the drying outlet 30.

Next, the case of performing deodorizing operation will be explained using FIG. 2. By reversing the electric motor 42, the downstream centrifugal impeller a
7 in the normal direction, the negative pressure in the ventilation passage 46 is made weaker than the strength of the coil spring 33, and the damper 26 is rotated toward the dry intake passage 28 to close the dry intake passage 28, thereby deodorizing the intake air. The air in the toilet bowl 21 is sucked into the deodorizing passage 24 from the opening 23, passes through the deodorizing agent 22, and the airflow subjected to the deodorizing action passes through the centrifugal impeller 36 on the upstream side and the centrifugal impeller 37 on the downstream side. From the deodorizing outlet 31 to the toilet bowl 21
It is discharged outside. However, in this case, a small amount of air is sucked into the interior from the drying outlet 30, but the opening/closing flap 32 provided at the drying outlet 30 has fallen downward due to its own weight! According to this configuration, by rotating the centrifugal impeller 36 on the upstream side in the normal direction, the coil spring 33 is rotated in the normal direction. By generating a strong negative pressure in the ventilation passage 46, the damper 26
The centrifugal blower 35 is opened from the drying inlet 27 and the deodorizing inlet 23 by opening the drying inlet 27.
An air flow is generated that flows through the drying outlet 30, and can be used for drying and deodorizing the local area at the same time. Also electric motor 4
2 is reversed to rotate the downstream centrifugal impeller 37 in the normal direction, a negative pressure weaker than the strength of the coil spring 33 is generated in the ventilation passage 46, and the damper 26 is closed. A rush flow is generated that flows from 23 to the deodorizing outlet 31 via the centrifugal blower 35, and can be used only for deodorizing operation.

On the other hand, by providing a rectifier plate 44 protruding from the casing 38, 39 in the direction of the coupling plate 41 so as to have a gap 45 between it and the outer circumference of the coupling plate 41, both blades can be arranged around the outer circumference of the coupling plate 41. This has the effect of preventing flow disturbances caused by mutual interference between the cars 36 and 37.

Effects of the Invention According to the present invention, by changing the rotational direction of the drive electric motor, the damper can be opened and closed, and at the same time, the discharge direction from the centrifugal blower can be changed. The configuration of the toilet seat device can be simplified and the size of the toilet seat device can be reduced at the same time.
