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 warm water etc. after defecating, and then drying them with warm air, and the function of deodorizing odors. It is.

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 an air supply port 8, and has a built-in blower 8 and an electric heater 9, which are constituted by 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, but a deodorizing agent is placed in place of the electric heater 9, and the air flow in the opposite direction to that of the drying device B, that is, the inside of the toilet bowl 1. A deodorizing device configured to discharge air outside the toilet bowl 1 has been used either alone or in conjunction 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.

The present invention is intended to solve these conventional problems, and aims to provide a toilet seat device that has both drying and deodorizing functions using a single electric motor, and that is also miniaturized.

Means for Solving the Problems The present invention provides a first centrifugal impeller comprising two centrifugal impellers having a common suction port and whose blades have different arcuate directions with respect to the same suction direction, and their respective casings. A second blower consisting of a blower and a centrifugal impeller and a casing are fixed coaxially to a single reversible electric motor, and a deodorizer is placed upstream of the first blower into the toilet bowl. A deodorizing intake passage with an open deodorizing intake port is provided, a deodorizing outlet opening to the outside of the toilet bowl is provided on the downstream side, and a drying intake port opening to the outside of the toilet bowl is provided on the upstream side of the second blower. established,
A drying outlet opening into the toilet bowl is provided on the downstream side via an electric heater.

Effect: With the above-described configuration, the present invention can provide a small-sized toilet seat device that has both drying and deodorizing functions using one electric motor, and is always able to operate regardless of the direction of rotation of the electric motor. The deodorized air can be discharged outside the toilet bowl.

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

FIG. 1 shows a case where the centrifugal impeller on the upstream side of the first blower and the centrifugal impeller of the second blower of this device A are rotated normally to perform local drying and deodorizing functions at the same time. FIG. 2 shows a case where the deodorizing effect is performed with the centrifugal impeller on the downstream side of the first blower being rotated normally. 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 has a deodorizing intake that opens into the toilet bowl 21 via a deodorizing agent 22 upstream of a first blower a that supplies deodorizing air. Mouth 23
A deodorizing intake passage 24 is provided, and deodorizing discharge ports 25c and 26c that open to the outside of the toilet bowl 21 are provided on the downstream side. Also, on the upstream side of the second blower, there is a drying intake port 27.
A dry air intake path 28 is provided which opens to the outside of the toilet bowl 21 through the
A drying outlet 30 that opens into the toilet bowl 21 via an electric heater 29 is provided on the downstream side.

Further, the drying outlet 30 is provided with an opening/closing flap 31 that automatically opens and closes depending on the pressure of the air flow passing therethrough and its own weight.

Further, the first blower a has two types of blades 25 a * 26 a having different arc directions with respect to the same suction direction, and a double centrifugal impeller 25 , 26 having a common air inlet 32 . and each casing 25b, 2
Furthermore, between the upstream centrifugal impeller 25 and the downstream centrifugal impeller 26, an axial impeller 38 corresponding to the arc direction of the blade 26a is disposed, and the upstream centrifugal impeller 38 The respective impellers are arranged so that air flows from the impeller 25 to the centrifugal impeller 26 on the downstream side via the axial impeller 38. - The blower of the power tube 2 consists of a series of centrifugal impellers 33, a casing 34 and an air inlet 35. Furthermore, the first blower d and the second blower d
The blowers 1 and 2 are coaxially fixed to a motor 36, such as a transistor motor, which can be rotated in forward and backward directions, so that both blowers a and b rotate at the same time about the same rotation axis. In addition, in FIG. 1 and FIG. 2, 37 indicates the exterior of the toilet seat assembly @A.

Next, the case where local drying operation and deodorizing operation are performed simultaneously will be explained using FIG. The centrifugal impeller 25 on the upstream side of the first blower a and the centrifugal impeller 33 of the second blower (*b) are deodorized by rotating the electric motor a6, which can be rotated forward and backward, so that the centrifugal impeller 33 is in the normal rotation direction. The air in the toilet bowl 21 is passed through the deodorizing intake port 23 to the deodorizing intake passage 24.
The deodorizing fluid is sucked in by the upstream centrifugal impeller 25 and discharged out of the toilet bowl 21 from the deodorizing discharge port 25C. On the other hand, drying air is supplied to the drying intake port 27 by the rotation of the second blower.
The more sucked air is sent to the electric heater 29, where it is heated to become warm air, which is then discharged into the toilet bowl 21 through the drying outlet 30 and used for drying the private parts. Further, the opening/closing flap 31 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. By rotating the main motor 36, which is capable of forward and reverse rotation, so that the centrifugal impeller 26 on the downstream side of the first blower a is in the normal rotation direction, the deodorized air is passed through the toilet bowl 2 through the deodorizing intake 23.
1 is sucked into the deodorizing intake passage 24, passes through the deodorizing agent 22, and the airflow subjected to the deodorizing action is sucked into the first blower a from the blowing port 32. The airflow sucked into the first blower/shade a passes through the inside of the centrifugal impeller 25 on the upstream side, and then passes through the axial impeller 38 to the centrifugal impeller 26 on the downstream side. It flows into the toilet bowl 2 from the deodorizing outlet 26C.
1 is discharged outside. On the other hand, since the centrifugal impeller 33 constituting the second blower rotates in the opposite direction to the normal rotation, almost no air is sucked in from the drying intake port 27. Furthermore, the opening/closing flap 31 provided at the drying outlet 3o hangs downward due to its own weight and closes the drying outlet 30.
leakage can be prevented.

According to this book, by rotating the electric motor 36 in the normal direction, an air flow is generated that flows from the deodorizing inlet 23 to the deodorizing outlet 25c via the first blower a, and also flows through the second blower to the drying outlet. It creates an air flow that flows through the air, and can be used for drying and deodorizing local areas at the same time. Further, by rotating the electric motor 36 in the reverse direction, air temperature is generated that flows from the deodorizing intake port 23 to the deodorizing outlet 25c via the first blower a, and can be used only for deodorizing operation. Furthermore, by arranging the axial flow type impeller 38 between the centrifugal type impellers 25 and 26, the downstream centrifugal type impeller 25 and 26 can be more effectively
Air can be supplied to 6.

Effects of the Invention As described above, according to the present invention, it is possible to have both drying and deodorizing functions using one electric motor, and
By changing only the rotating direction of the electric motor, the deodorizing function can be used in addition to the drying function, and the structure of the blower can be simplified and the structure of the toilet seat device can be made smaller.
