Description

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

2. Description of the Related Art Conventionally, in this type of device, as shown in FIG. A drying device B is provided in the ventilation path S, which constitutes a ventilation path 5 that communicates with the air supply port 3, and includes a built-in blower 8 and an electric heater 9, which are comprised of an impeller 6 and a motor 7 that drives the impeller 6. ing. and,
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. It was used for drying. 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 the drying bag fIIB.
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 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 two sets of centrifugal impellers having two types of blades having different arc directions on both sides of a main plate and having independent air inlets, and a casing for each. A first blower consisting of a blower and a second blower consisting of a series of centrifugal impellers and a casing are fixed coaxially to a reversible electric motor, and a deodorizer is placed upstream of the first blower to install the toilet bowl. A deodorizing intake passage with a deodorizing intake port opening inward is provided, a deodorizing outlet opening outside the toilet bowl is provided on the downstream side, and a drying intake port opening outside the toilet bowl is provided on the upstream side of the second blower. A drying outlet opening into the toilet bowl via an electric heater is provided on the downstream side.

Function: With the above-described configuration, the present invention can provide a compact toilet seat device by providing both drying and deodorizing functions using a single electric motor, and regardless of the rotational direction of the electric motor, Deodorized air can always be discharged outside the toilet bowl.

Embodiments Below, embodiments of the present invention will be described with reference to FIGS. 1 and 2.

FIG. 1 shows a case in which the centrifugal impeller on the upstream side of the first blower and the centrifugal impeller of the second blower to this device 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 addition, Fig. 1.

In FIG. 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 through the opening and its own weight.

Further, the first blower a has two types of blades 25a on both sides of the main plate 32 with different arc directions.

26a and an independent air inlet 25b.

a double series of centrifugal impellers 25, 26 having 26b;
The second blower is composed of the respective casings 25d and 28d, and the second blower is composed of a series of centrifugal impellers 33, a casing 34, and an air inlet 35. Further, the first blower a and the blower @2 are coaxially fixed to a reversible electric motor 36 such as a transistor motor, so that both blowers a and b rotate at the same time about the same rotation axis. are doing. In addition, 37 in FIG. 1 upper part and FIG. 2 shows the exterior of the toilet seat apparatus A.

Next, the case where local drying operation and deodorizing operation are performed simultaneously will be explained using FIG. The deodorized air is deodorized by rotating the rotary exciter 36, which can be rotated forward and backward, so that the centrifugal impeller 25 on the upstream side of the first blower a and the centrifugal impeller 33 of the second blower are in the normal rotation direction. The air inside the toilet bowl 21 is sucked into the deodorizing intake passage 24 through the deodorizing intake port 23, and is discharged to the outside of the toilet bowl 21 through the deodorizing outlet 25c by the centrifugal impeller 25 on the upstream side. On the other hand, the air for drying is sucked through the drying intake port 27 by the rotation of the second blower and sent to the electric heater 29, where the air is heated and becomes warm air, which is then discharged for drying. It is discharged into the toilet bowl 21 through the outlet 30 and used for drying the private parts. Also,
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 electric motor 36, which can be rotated forward and backward, so that the centrifugal impeller 26 on the downstream side of the first blower a is in the normal rotation direction, the toilet bowl 21 is
The air inside is sucked into the deodorizing intake passage 24, passes through the deodorizing agent 22, and the deodorized air flow is discharged to the outside of the toilet bowl 21 from the deodorizing outlet 26c via the centrifugal impeller 26 on the downstream side. On the other hand, a centrifugal impeller 33 constituting the second blower
rotates in the opposite direction to the normal rotation, so that almost no air is sucked in from the drying intake port 27. Furthermore, an opening/closing flap 31 provided at the drying outlet 30
The drying discharge port 30 is closed when the drying discharge port 30 is hung downward due to its own weight, so that outflow from the drying discharge port 30 can be prevented.

According to this configuration, by rotating the electric motor 36 in the normal direction, an air flow is generated that flows from the deodorizing intake port 23 to the deodorizing outlet 25c via the first air blower ala, and also to the drying outlet 3o via the second blower. It creates a flowing air stream and can be used to dry and deodorize local areas at the same time. Further, by rotating the electric motor 36 in the reverse direction, an air flow is generated that flows from the deodorizing inlet 23 to the deodorizing outlet 26c via the blower a of @1, and can be used only for deodorizing operation.

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.
