Description

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

Conventional Structure and Problems Conventionally, in this type of device, as shown in FIG. A drying device A is provided which constitutes a ventilation path 5 and has a built-in blower 8 and an electric heater 9 which are constituted by an impeller 6 and a motor 7 for driving the impeller 6 in the ventilation path 5.

Then, place this dry-smoked MA at the upper rear of flight RR1,
By energizing the electric heater 9 and operating the blower 8, an air flow C (indicated by the solid line arrow in the figure) from the suction port 3 to the discharge port 2 is formed. 2
It was discharged into stool N1 and used to dry the private parts. For deodorizing when using the toilet, the structure is similar to that of the drying device A, and a deodorizing agent is placed on the base of the electric heater 9, and the air flows in the direction opposite to that of the drying device A, that is, inside the toilet bowl 1. A deodorizing device configured to discharge the air of feces H,y to the outside has been used either alone or in conjunction with a drying device.

However, in such a configuration, the noise generated by the blower 8 is emitted to the outside via the air supply O.
There was an issue that made me feel uncomfortable.

OBJECTS OF THE INVENTION The present invention solves the problems of the prior art.
The purpose of this is to reduce the gate noise by installing a shield box for sound insulation.

Structure of the Invention In order to achieve this object, the present invention has a deodorizing passage with a built-in deodorizer on the upstream side of the blower, a drying air supply port opened and closed by a first damper, and a drying path with a built-in electric heater on the downstream side. A deodorized air discharge [-1] is opened and closed at the passageway and the casing of the blower, and is opened and closed by a second damper; Since the shield box has a structure in which 1) the lower part in the axial direction of the stenographic machine is opened, a low-noise toilet seat device can be constructed.

DESCRIPTION OF EMBODIMENT 1 An embodiment of the present invention will now be described with reference to FIGS. 2 to 5. Fig. 2 td shows a partial sectional view of the present device B arranged on the toilet bowl 21 during deodorizing operation, and Fig. 3 shows an enlarged view of its main parts. Moreover, FIG. 4 shows an enlarged view of the main parts during drying operation, and FIG. 5 is a perspective view showing the structure of the damper. In FIGS. 2 to 5, the same numbers are used for the same parts, solid line arrows indicate air flow during drying operation, and broken dashed line arrows indicate air flow during deodorizing operation. In FIGS. 2 to 5, the motor for driving the blower is placed upstream of the blower and is not shown in the drawings.

As shown in FIGS. 2 to 5, this device B includes a centrifugal impeller 26 and a casing 27 surrounding the outer circumference of the centrifugal impeller 26 in a spiral shape.
A multi-blade blower 28 is connected to the upstream side of the blower 28, and a deodorizing path 25 is connected to the upper end thereof as a deodorizing air supply port 22 and opens into I'j ag2 i, and has a built-in deodorizing agent 23. On the downstream side of the blower 28, a dry warm air discharge port 3o is opened in the toilet bowl 21, and a drying path 31 containing an electric heater 29 is connected to form an air flow path. The blower 28 is provided with a fixed tongue portion 32 that forms a part of the casing 27 and the drying path 31, and further includes a deodorized air outlet 33 that is opened in the casing 27 and a second damper 34 that opens and closes the drying path 31. position 1 at the tip of
A movable tongue portion 35 is provided which moves in response to the opening and closing of the damper 34. Furthermore, a dry air power supply port 36 is provided on the upstream side of the blower, and a communication port 39 is provided inside the dry air power supply port 36, which opens at the lower part of the blower 28 in the axial direction, and a communication port 39 is provided inside the dry air power supply port 36, and the first damper 34'
The communication port 39 is opened and closed by a)I/l/' box 38, and the first damper 34 and the second damper 34 are coaxially rotatable, and the first damper 34
A microswitch 42 is installed near the 1000 Ω, and during deodorizing operation, the microswitch operates to reduce the voltage applied to the blower motor (not shown) or turn off the tap to reduce the motor rotation speed. The configuration is configured to lower the amount. The hot dry air outlet 30 is provided with a back wind plate that closes the dry hot air outlet 30 by its own weight and is pushed outward and upward by the warm air during drying operation to open the dry hot air outlet 30. There are 37. In addition, 40 is the toilet bowl 21
A tank 7.41 for storing water for washing the inside is a toilet seat, and 24 is an exterior of a water bag fiB.

Next, the operation when performing the deodorizing operation will be explained using FIG. 3.

The second damper 34 is positioned to provide a gap between the fixed tongue part 32 and the movable tongue part 35 to open the deodorized air outlet 33, and at the same time, the first damper 34' is used to open the communication opening of the shield box 38. By driving the blower 28 with the air blower 39 closed, as shown by the dashed line arrow in the figure,
At the same time that a flow is formed from the deodorizing air supply port 22 to the deodorizing discharge port 33 via the impeller 26, an air flow is also drawn from the dry hot air discharge port 30. However, the suction airflow from the dry hot air outlet 30 is blocked by the back wind plate 37.
be done. Therefore, the air flow during deodorizing operation is limited to the deodorizing air supply port 22.
The airflow is only from the air, and the deodorizing effect can be demonstrated. On the other hand, by positioning the movable tongue portion 35 as shown in FIG. 3, the amount of air flowing out to the deodorized air outlet 33 can be increased. That is, when the damper 34 is rotated to the fixed tongue portion 32, a significant collision flow occurs, but by eliminating this occurrence,
This can significantly reduce the blower load. Therefore, even if the impeller 26 is rotated at a low speed by operating the microswitch 42, a sufficient deodorizing effect can be obtained, and at the same time, the noise generated inside the blower 28 can be significantly reduced.

Next, the operation during drying operation will be described using FIG. 4.

The second damper 34 is rotated to close the deodorized air outlet 33, and at the same time, the communication port 39, which had been closed by the first damper 34', is opened, and the blower 28 is driven to open the dry air supply port 36. At the same time, a flow is formed from the air to the dry hot air outlet 30 via the impeller 26, and at the same time, the back wind plate 37 is pushed outward and upward to the dry hot air outlet 3o.
becomes open. By energizing the electric heater 29 in this state, hot air can be generated. On the other hand, blower 2
8, a shielding box 38 with a communication port 39 arranged downwardly is provided in the dry air supply port 36, which has a shielding effect against the noise and prevents the dry air from discharging from the dry air discharge port 36. Noise emitted to the outside of the exterior 24 can be significantly reduced.

Effects of the Invention According to the present invention, the dry air supply port is provided with a seal F box,
Since the shield box has a configuration in which the lower part in the axial direction of the blower is opened, the noise emitted to the outside from the dry air supply port can be significantly reduced, and a comfortable toilet seat device can be realized. It is something.
