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, a function of deodorizing the inside of the toilet bowl, or a function of heating the inside of the toilet. The present invention relates to a toilet seat device used in a Western-style toilet bowl or the like.

Conventional Structure and Problems Conventionally, in this type of device, as shown in FIG. A drying device A which constitutes an air passage 5 and has an impeller 6 in the air passage 5, a blower 8 constituted by a motor 7 for driving all of these, and an electric heater 9.
' has been established.

The drying device Ai is placed at the rear of the upper part of the toilet bowl 1, and by energizing the electric heater 9 and operating the blower 8, the airflow from the suction port 3 to the discharge port 2 (indicated by the solid line arrow in the same 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. Also,
For deodorizing when using the toilet, the structure is similar to that of the drying/drying device A, and a deodorizing agent is placed on the base of the electric heater 9. A deodorizing device for discharging air outside the toilet bowl 1 has been used either alone or in combination with a drying device.

On the other hand, for the heating in the toilet room, a damper (not shown) in a part of the drying device A is opened and hot air is discharged into the entire room after passing through the electric heater 9, or the warm air is heated independently from the toilet seat device. A configuration has been adopted in which temperature-controlled air is blown into the toilet seat 10 using a blower (not shown) or the like and then released into the toilet room.

However, although such a configuration has the advantage that each device can be operated independently, it also requires the installation of each device around the toilet bowl, and the problem is that the entire device becomes large as it has all the functions. was there.

Purpose of the Invention The present invention solves all of the problems of the conventional technology, by providing a drying function, a deodorizing function, and an indoor heating function using the same blower without completely reversing the rotational direction of the blower, thereby reducing the size of the device. The overall purpose is to achieve this goal.

Structure of the Invention In order to achieve all of the above objects, the present invention includes a deodorizing path containing a built-in deodorizer on the upstream side of a multi-blade blower, a drying/heating path containing a built-in electric heater on the downstream side, and The multi-blade blower has a fixed first tongue and a second tongue that is located at the tip of a damper that switches between the deodorizing path and the drying/heating path and is movable together with the damper. , the casing of the multi-blade blower is provided with a deodorizing and heating air outlet that is opened and closed by the damper.

According to the above configuration, by using one multi-blade blower and changing the opening/closing position of one damper, it is possible to obtain the three functions of drying, deodorization, and indoor heating, and the multi-blade blower Easily reverse the direction of air flow flowing into the electric heater without reversing the rotation direction of the
It can be used as both a drying path and an indoor heating path.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 2 to 5. FIG. 2 shows the device Bi installed on a toilet bowl 21 in the case where indoor heating and deodorization are performed simultaneously, and FIG. 3 shows its main parts.

In FIGS. 2 and 3, dash-dotted line arrows indicate the flow of deodorized air, and solid line arrows indicate the flow of heating air.

Fig. 4 shows the device B placed on the toilet bowl 21 for deodorizing and drying at the same time, and Fig. 5 shows its main parts. In FIGS. 4 and 5, dash-dotted arrows indicate the flow of deodorized air, and the same parts are designated by the same numbers in FIGS. 2 to 5.

Referring to FIGS. 2 and 3, a case where sect heating and deodorization are performed at the same time will be explained. A centrifugal impeller 26,
A deodorizing agent 23 is built into the upstream side of the multi-blade blower 28, which is composed of a casing 27 surrounding the outer peripheral surface in a spiral shape, and is opened into the toilet bowl 21 as an air supply port 22 for complete deodorization at the upstream end. 25, and an electric heater 29 is installed downstream of the multi-blade blower 28 at the downstream end. The drying/heating channel 1 opened to the toilet bowl 21 is connected as a drying hot air outlet 3o to form an air flow path, and the multi-blade blower 28 has a gauging 27 and a part of the drying/heating channel 31. A fixed first tongue 32 is provided which completely forms the casing 2.
The deodorizing/heating air outlet 3a opened at 7 and the drying/heating path 31 are located at the tip of the damper 34 which fully opens and closes, and are provided with 35 second tongues that move in accordance with the opening and closing of the damper 34. 36 is a tank for storing water for washing the inside of the toilet bowl 21, 37 is a toilet seat, and 24 is an exterior of the device. Further, in FIG. 3, the motor for driving the impeller 26 is disposed upstream of the impeller 26, but is omitted here.

Next, a case will be described in which indoor heating and deodorizing are performed simultaneously. The damper 34 is positioned to provide a gap between the first tongue portion 32 and the second tongue portion 35 to fully open the deodorizing and heating air outlet 33, and the impeller 26
〜Drying warm air discharge chamber 30 is in communication state, and the blower 28
By fully driving the air, a flow is formed from the deodorizing air supply port 22 to the deodorizing and heating air outlet 33 via the impeller 26, as shown by the dot-dashed line arrow in Figure 3, and at the same time, as shown by the solid line arrow, From the drying hot air outlet 30 to the impeller 2
6, a flow is formed to the deodorizing and heating air outlet 33. In this state, by energizing the electric heater 9,
The air sucked in from the 30 drying hot air outlets is heated and can be used for room heating. On the other hand, deodorizing air supply port 2
When the air flow sucked in from the blower 28 passes through the built-in deodorizer 23, it is deodorized and reaches the blower 28 as odor-free air.In other words, it can provide both indoor heating and deodorizing functions at the same time. .

In addition, by closing the deodorizing and heating air outlet 33 with the damper 34 as shown in FIGS. 4 and 5, the air flow sucked from the deodorizing air supply port 22 as shown by the dashed-dotted line arrow is The hot air is discharged from the drying hot air outlet 30 via the blower 28, and by energizing the electric heater 29 in this state, both deodorizing and drying functions can be obtained at the same time. Furthermore, the damper 34 causes the first tongue portion 32 to
By closing the space between the deodorizing air supply port 22 and the second tongue portion 35, the air flow sucked from the deodorizing air supply port 22 passes through the blower 28 and is discharged from the deodorizing/heating air outlet 33, thereby achieving a deodorizing function.

Effects of the Invention According to the present invention, by completely changing the opening/closing position of one damper using one blower, it is possible to completely reverse the flow direction of air flowing into and out of the electric heater. The passageway for passing hot air and the passageway for passing hot air for heating can all be used in common. Therefore the air duct can be completely simplified,
Moreover, it has the advantage of being able to be constructed in a small size.

Furthermore, since the deodorizing air flows all the way around the motor during room heating operation, it is also possible to suppress the rise in temperature of the motor.
