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 path 5 that communicates with the air supply port 3, and also includes 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 path 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 the three functions of drying, deodorizing, and private part cleaning using a single electric motor, and that is also miniaturized. .

Means for Solving the Problems The present invention provides a first blower comprising two centrifugal impellers having a common intake port and whose blades have different arcuate directions with respect to the same intake direction, and respective casings. A second blower consisting of a series of centrifugal impellers and a casing, and a pump that supplies local cleaning water through a clutch mechanism that connects and disconnects power depending on the direction of rotation are combined into a single electric motor that can be reversed in the forward and reverse directions. The first blower is fixed coaxially, and has a deodorizing intake passage with a deodorizing inlet opening into the toilet bowl through a deodorizing agent on the upstream side of the first blower, and a deodorizing outlet opening outside the toilet bowl on the downstream side. In addition, a drying intake port opened to the outside of the toilet bowl is provided on the upstream side of the second blower, and a drying discharge port opened into the toilet bowl via an electric heater is provided on the downstream side.

Effects of the Invention With the above-described configuration, the present invention can provide a compact toilet seat device by using one electric motor and having three functions of drying, deodorizing, and private part cleaning, and also provides a toilet seat device that can be used regardless of the direction of rotation of the electric motor. Added deodorizing function, and
Deodorized air can always be discharged outside the toilet bowl.

EXAMPLE An example of the present invention will be described below with reference to 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 centrifugal impeller on the downstream side of the first blower is rotated normally to perform the deodorizing action and the local cleaning action.

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.

Toilet seat device A of the present invention as shown in FIG. 1 and ¥12
A deodorizing intake port 2 opens into the toilet bowl 21 via a deodorizing agent 22 on the upstream side of the first blower a that supplies deodorizing air.
A deodorizing intake passage 24 is provided with a toilet bowl 21 on the downstream side.
Deodorizing outlets 25c and 26c are provided which are open to the outside. Also, on the upstream side of the second blower, there is a drying intake port 2.
A drying air intake passage 28 is provided which opens to the outside of the toilet bowl 21 through an electric heater 29, and a drying outlet 30 which opens into the toilet bowl 21 through 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 centrifugal impellers 25.2 that are provided with two types of blades 25a and 26a having different arc directions with respect to the same suction direction, and have a common intake port 32.
6 and the respective casings 25b and 26b, and further 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. The impellers are arranged such that air flows from the centrifugal impeller 25 on the upstream side to the centrifugal impeller 26 on the downstream side via the axial flow impeller 38. On the other hand, the second blower is composed of a series of centrifugal impellers 33, a casing 34, and an intake port 35. In addition, the first blower a and the second blower are coaxially fixed to a motor 36, such as a transistor morph, which can be rotated forward and backward, so that both blowers a and b rotate at the same time on the same rotation axis. At the same time, the electric motor 36 has
Pump 38 (pump 3
The supply waterway to 8 and the discharge waterway from the pump 38 are not shown. ) are also arranged to rotate on the same axis. Further, the electric motor 36 and the pump 38 are connected via a clutch mechanism 39 that connects and disconnects the power transmitted to the pump 38 depending on the rotational direction of the electric motor 36 using, for example, a spring. Note that the clutch mechanism 39 is configured to cut off the power from the electric motor 36 when the second blower rotates in the normal direction.

In addition, in FIGS. 1 and 2, 37 indicates the exterior of the toilet seat device A.

Next, a case where local drying operation and deodorizing operation are performed simultaneously will be explained using FIG. The deodorized air is deodorized by rotating the electric motor 36, which is capable of forward and backward rotation, 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. Air in the toilet bowl 21 is sucked into the deodorizing intake passage 24 through the intake port 23, and is discharged to the outside of the toilet bowl 21 from the deodorizing discharge port 25c by the centrifugal impeller 25 on the upstream side. On the other hand, the air for drying is sucked from the drying intake port 27 by the rotation of the second blower and is sent to the electric heater 29, where the air is heated and becomes warm air. The water is discharged into the toilet bowl 21 through the pipe 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/drying outlet 30. On the other hand, on the 3rd day of the pump, the clutch mechanism 39
Since the power of the electric motor 36 that is transmitted to the pump 38 by the pump 38 is not transmitted, that is, it is cut off, the supply of cleaning water is stopped.

Next, the case where the deodorizing operation and the private part cleaning operation are performed will be explained using FIG. The deodorizing inlet 2 is rotated 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 rotated in the normal rotation direction.
3, the air in the toilet bowl 21 is sucked into the deodorizing intake passage 24, passes through the deodorizer 22, and the airflow that has been deodorized is sucked into the first blower a from the suction port 32. The air flow sucked into the first blower a is transferred to the centrifugal impeller 2 on the upstream side.
The air flow passes through the inside of the 5 and flows into the centrifugal impeller 26 on the downstream side via the axial impeller 38, and the air flows through the deodorizing outlet 26c.
from the toilet bowl 21. On the other hand, since the centrifugal impeller 33 constituting the second blower rotates in the opposite direction to the normal rotation, little air is sucked in from the drying intake port 27. Furthermore, the opening/closing flap 31 provided at the drying outlet 30 hangs downward due to its own weight and closes the drying outlet 30f, so that the outflow from the drying outlet 30 can be prevented. On the other hand, the pump 38 is controlled by the clutch mechanism 39.
Since the power of the electric motor 36 is transmitted to the body, that is, in the connected state, the washing water is supplied and the private parts can be washed.

According to this configuration, by rotating the electric motor 36 in the normal direction, the air is passed from the deodorizing intake port 23 to the first blower a, and then to the deodorizing outlet 2.
5c, and also generates an air flow that flows to the drying outlet 30 via the second blower, so that it can be used for drying and deodorizing the private parts at the same time. Further, by rotating the electric motor 36 in the reverse direction, a rush flow is generated that flows from the deodorizing intake port 23 to the deodorizing outlet 26c via the first blower a, thereby performing a deodorizing operation. At the same time, the clutch mechanism 39 transmits the power of the electric motor 36 to the pump 38.
It is possible to perform a cleaning operation in which the private parts are cleaned by driving the . Furthermore, the axial flow type impeller 38 is replaced with the centrifugal type impeller 25.26.
By arranging it between 0 and 0, air can be more effectively sent to the centrifugal impeller 26 on the downstream side.

Effects of the Invention As described above, according to the present invention, it is possible to provide the three functions of drying, deodorization, and private part cleaning using one electric motor, and to perform the drying function by changing only the rotation direction of the electric motor. In addition to switching the deodorizing function to
The configuration of the blower can be simplified and at the same time the configuration of the toilet seat device can be downsized.
