Description

[Detailed Description of the Invention] Industrial Application Field The present invention has a function of washing the private parts with hot water etc. after defecating and then drying them with warm air, and a function of forcibly deodorizing the odor emitted from the inside of the toilet bowl. This invention relates to a toilet seat device used in Western-style toilets, etc.

Structure of conventional example and its problems Conventionally, in this type of device, as shown in FIG.
A discharge port 2 that opens inward and an air supply port 3 that opens outside the toilet bowl 1 are provided to form a ventilation passage 5 within the exterior 4, and an impeller 6 and a motor 7 that drives the impeller 6 are provided within the ventilation passage 5. A drying device A is provided which includes a built-in blower 8 and an electric heater 9.

This drying device A is arranged at the rear of the upper part of the toilet bowl 1, and by energizing the electric heater 9 and operating the blower 8, air flows from the suction port 3 to the discharge port 2 (indicated by the solid line arrow in the figure). ), heated by an electric heater 9, and then discharged into the toilet bowl 1 from the discharge port 2 to dry the private parts. For deodorizing the toilet bowl, it has a similar configuration to the dryer mentioned above.
A deodorizing agent is placed in place of the electric heater 9, and a deodorizing device is installed with the drying device, which has a configuration in which the air flows in the opposite direction to that of the drying device, that is, the air inside the toilet bowl 1 is discharged to the outside of the toilet bowl 1. 7, that is, the impeller 6 is reversed to change the direction of air flow during drying and deodorizing.

However, when the same impeller is used for both forward rotation and reverse rotation, the air blowing capacity decreases significantly, and for this reason, the impeller 6 must be rotated at a high speed or the impeller 6 must be made larger. Problems arose.

OBJECTS OF THE INVENTION The present invention solves the conventional problems, and aims to smoothly switch the air flow during drying and deodorization, and to downsize the apparatus.

Structure of the Invention In order to achieve this object, the present invention provides a passage switching system in which one cylindrical rotating body is provided on the upstream side and one downstream of the blower, and both rotating bodies are coaxially rotatable integrally. In addition, one rotating body is constructed with a deodorizer or an electric heater.

With the above configuration, it is possible to switch between the drying path and the deodorizing path by rotating the path switching device while always keeping the rotational direction of the blower constant.

That is, since the blower can be designed in a shape that maximizes its blowing capacity, it is easy to design low-speed rotation or miniaturization. ＠Sound can be significantly reduced, and the device can also be made smaller.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 2 to 4. FIG. 2 shows a front view of the wooden @B placed on the toilet bowl 21, FIG. 3 shows a plan view, and FIG. 4 shows a perspective view. In the figure, the same numbers indicate the same parts, and solid arrows indicate the air flow inside the device.

As shown in @Figures 2 to 4, this device B has a blower 28 that is composed of an impeller 26 and a motor 27 that drives the impeller 26.
On the upstream side of the blower 28, there is arranged a ventilation passage 25 having an inlet 22 whose other end is open into the toilet bowl 21, and on the downstream side, a ventilation passage 25 having an outlet 22' whose other end is open into the toilet bowl 21. A dual-speed airway 25 is disposed within the exterior 24.
and 26' are arranged in two stages, upper and lower. Furthermore, cylindrical rotating bodies 23 and 23 are disposed in both speed air passages 25 and 25'.
' constitutes a passage switching device 30 that can be rotated coaxially and integrally with the rotating shaft 29, and the rotating body 23 in the ventilation passage 26...
A deodorizing agent 31 in the form of a comb and a coil-shaped electric heater 31' are installed in the rotary body 23' in the air passage 25', and each rotary body 23. Air passage 25 corresponding to the side of '23'
+ 25' side walls 32, 32' are provided with an air supply port 33 and an air exhaust port 33' that communicate with the outside of the exterior 21. On the other hand, both rotating bodies are configured to be able to block or vent the flow of air from the suction port 22 to the blower 28 or from the blower 28 to the discharge port 23' by rotating 9CP. It is configured so that it can communicate with the outside of the exterior 21 via an air supply port 32 or an air exhaust port 32' provided on the roadside wall 32° 32'. Further, both the rotating bodies 23 and 23' are connected to the inlet 2 by the rotating body 23.
When blocking the air flow from 2 to the blower 28,
The rotating body 23' is configured to rotate integrally with the rotating body 23' so as to ventilate the flow of air from the blower 28 to the discharge port 22'.

Next, the deodorizing action will be explained using FIG. 4. The passage switching device 30 is rotated to allow the flow of air from the suction port 22' to the blower 28, and the blower 2
8 to the discharge port 22', the rotating body 23 closes the air supply port 32, and at the same time, the rotating body 23' opens the exhaust port 32'.
As shown by the solid arrow, the air flow by the blower 28 is as follows.
From the suction port 22 to the rotating body 23. Exhaust port 3 via blower 28
2' to form an air flow flowing out of the outer casing 21.

On the other hand, since a honeycomb-shaped deodorizing agent 31 is incorporated in the rotating body 23, when the airflow passes through the 1!21 rotating body 23, the odor sucked from the suction port 22 is deodorized and the odor is removed. The removed airflow is discharged to the outside of the exterior casing 21 and acts as a deodorizer.

On the other hand, when using it as a dryer, the passage switch 30 is
By rotating the fan 28 from the suction port 22
The air supply port 33 is opened and the exhaust port 33' is closed.
2' is made ventilable, heated by an electric heater 31' installed in the rotating body 23' at -1 fL, and discharged from the discharge port 22' for use in drying local areas. .

Effects of the Invention According to the invention, the ventilation path during deodorization and drying can be switched by rotating a cylindrical path switch incorporating a deodorizer or an electric heater, so the direction of rotation of the blower can be reversed. Therefore, it is possible to design a blower that can maximize the blower function. Therefore, it is possible to prevent an increase in noise due to the high-speed rotation of the blower, or to prevent the device from increasing in size due to an increase in the size of the blower, thereby making it possible to downsize the device. Further, by integrally incorporating the passage switching device and the deodorizing agent or the electric heater, the passage switching device can be made smaller, and therefore the device can also be made more compact.
