It was necessary to install a stand, which resulted in the problem of increasing the size of the entire device.

The present invention solves the conventional problems, and aims to provide a toilet seat device that is miniaturized by providing both drying and deodorizing functions with a single blower.

Means for Solving the Problems In order to solve the above problems, the present invention has a deodorizing path on the upstream side of the blower and a discharge path on the downstream side, and the deodorizing path includes a deodorizing agent made of, for example, activated carbon molded into a honeycomb shape. A deodorizing intake port is provided that opens into the toilet bowl through a coil-shaped electric heater, and a discharge port that opens into the toilet bowl through, for example, a coil-shaped electric heater and is provided with an opening/closing flap. A drying inlet opening to the outside of the toilet bowl is provided between the deodorizing agent and the drying inlet, and a damper that opens and closes using a shape memory alloy that operates when heated by electricity is arranged in the drying inlet, and the shape memory alloy is , in the airflow passing through the drying inlet when the drying inlet is open.

Function: With the above-described configuration, the present invention can provide both drying and deodorizing functions using a single blower, so it is possible to provide a toilet seat device that is extremely miniaturized.

EXAMPLE Hereinafter, an example of the present invention will be explained using FIGS. 1 and 2.

FIG. 1 shows the device B in a case where the drying inlet 19 is opened to perform a local drying action, and FIG. 2 shows a case in which the drying inlet 19 is closed to perform a deodorizing action. Further, in both figures, solid line arrows indicate the flow of local drying air, and dashed-dotted line arrows indicate the flow of deodorizing air.
.

As shown in Figures 1 and 2, a deodorizing passage 13 is arranged on the 5 page side upstream of the blower 12 that blows air for local drying and deodorizing, and a discharge passage 14 is arranged on the downstream side. The upstream end of the passage 13 is provided with a deodorizing intake port 16 that opens into the toilet bowl (not shown) through a deodorizing agent 15 made of activated carbon molded into a honeycomb shape, and the downstream end of the discharge passage 14 on the downstream side is provided with a deodorizing inlet 16 that opens into the toilet bowl (not shown) through a deodorizing agent 15 made of activated carbon molded into a honeycomb shape, for example. A discharge port 18 is provided which opens into the toilet bowl (not shown) through a shaped electric heater 17. Additionally, a toilet bowl (not shown) is provided between the blower 12 and the deodorizer 15.
A drying intake port 19 that opens to the outside is provided, and a damper 2 that opens and closes the drying intake port 19 is provided in the drying intake port 19.
0, and this damper 20 is opened and closed by a shape memory alloy 22 and an auxiliary spring 23 operated by electrical heating, and when the damper 20 is open, that is, when the drying intake port 19 is open, the air passing through it is A shape memory alloy 22 is arranged so as to be located in the flow. moreover,
The discharge port 18 is provided with an opening/closing flap 21 that automatically opens and closes depending on the pressure of the air flow passing through the discharge port 18 and its own weight. Note that 11 indicates the exterior of the toilet seat device B, and the damper 20.
The air resistance of the drying inlet 19 when the drying inlet 19 is opened using damper 2 is
0 is set to be smaller than the air resistance on the upstream side of the blower 12 when the drying intake port 19 is closed, that is, the air amount during drying operation is set to be larger than the air amount during deodorizing operation. ing.

Next, the case where local drying operation is performed will be explained using FIG. By energizing the shape memory alloy 22, the shape memory alloy 22 is given a tensile force greater than the tensile force of the auxiliary spring 23, and the damper 20 is operated to open the drying intake port 19 and the blower 12 is operated. The air outside the toilet bowl is sucked into the external device 1 through the drying intake port 19, passes through the electric heater 17 via the blower 12, and the airflow, which is turned into warm air by the electric heater 17, flows into the toilet bowl through the discharge port 18. It is discharged and used for drying the local area. On the other hand, since the deodorizing intake port 16 is always open even when the damper 20 is open, a small amount of air is sucked into the blower 12 via the deodorizing agent 15. That is, in this case, part of the deodorizing function can be obtained even during drying - and the opening/closing flap 21 provided on the outlet 7 page 18 is pushed upward by the air flow passing through the outlet 18. .

Next, the case of performing deodorizing operation will be explained using FIG. 2. By stopping the power supply to the shape memory alloy 22, the auxiliary spring 23 is given a tensile force greater than the tensile force of the shape memory alloy 22, and the damper 20 is operated to close the drying intake port 19 and operate the blower 12. As a result, the air inside the toilet bowl is sucked into the deodorizing passage 1a through the deodorizing intake port 16, passes through the deodorizing agent 15, and the airflow subjected to the deodorizing action is discharged into the toilet bowl from the discharge port 18 via the blower 12. Ru. In this case as well, the opening/closing flap 21 provided at the discharge port 18
is pushed upward by the air flow passing through the discharge port 18, but the air flow rate passing through the discharge port 18 is lower during deodorization than during drying, so it is difficult to open or close it. The opening degree of the flap 21 becomes smaller than when drying. Therefore, during the deodorizing operation, the discharged airflow is discharged downward by the opening/closing flap 21. That is, the airflow is not discharged toward the local area even when the user is using the toilet. Furthermore, since the shape memory alloy 22 is located in the airflow passing through the drying intake port 19, when transitioning from drying operation to deodorizing operation, that is, when electricity to the shape memory alloy 22 is stopped, the drying Air intake port 19
Since the shape memory alloy 22 is forcibly cooled by the air flow passing through, the tensile force of the shape memory alloy 22 decreases rapidly. Therefore, the closing operation of the damper 20 can be accelerated.

According to this configuration, the drying inlet 19 is opened by energizing the shape memory alloy 22, and an air flow is generated that flows from the drying inlet 19 and the deodorizing inlet 16 to the outlet 18 via the blower 12, The electric heater 17 generates warm air, which can be used to dry local areas. In addition, shape memory alloy 22
The drying inlet 19 is closed by stopping the energization, creating a void where the air flows from the deodorizing inlet 16 to the outlet 18 via the blower 12, and after the deodorizing effect is obtained by the deodorizing agent 15,
The opening/closing flap 21 of the discharge port 18 causes the discharge to be discharged below the discharge outlet 18, and can be used for deodorization.

Effects of the Invention According to the present invention, the blower has a deodorizing passage on the upstream side and a discharge passage on the downstream side, and the deodorizing passage has a deodorizing passage that opens into the toilet bowl through a deodorizing agent made of, for example, activated carbon molded into a honeycomb shape. An intake port is provided, and the discharge path is provided with a discharge port that opens into the toilet bowl through, for example, a coil-shaped electric heater and is provided with an opening/closing flap. The drying intake port is opened and closed by a damper operated by a shape memory alloy, and the blower load is adjusted so that the air flow rate during drying operation is higher than the air flow rate during deodorization operation. By setting this, you can obtain part of the deodorizing function even during drying operation,
A small toilet seat device having both drying and deodorizing functions can be provided using one blower.
