Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a toilet seat device used in a Western-style toilet bowl, etc., which has a function of washing private parts with warm water or the like after defecating and then drying them with warm air.

Conventional Structure and Problems Conventionally, in this type of device, as shown in FIG. A blower 8 and an electric heater 9 are provided in the ventilation path 5, which are composed of an impeller 6, a motor 7 that drives the impeller 6, and an electric heater 9.
A drying device A is provided with a built-in drying device A.

Then, this drying device A is placed behind the upper part of the toilet bowl 1, the electric heater 9 is energized, and the blower 8 is operated so that air flows from the air supply port 3 to the discharge port 2 (in the figure, solid line arrows ) was formed, heated by an electric heater 91, and then discharged into the toilet bowl 1 from the discharge port 2 to dry the private parts. On the other hand, in order to direct the hot air for drying to the local area, the discharge port 2 has a second
As shown in the figure, the configuration was such that the cross-sectional area gradually decreased toward the downstream, and the center of the discharge port 2 was directed toward the local area.

However, in the configuration, the discharge port 2
Since the direction of the airflow discharged from the is always in the same direction, when the drying of the local area starts, the airflow is not sufficiently warmed by the electric heater 9 and cold air flows to the local area, causing discomfort to the user. There was a point.

Purpose of the Invention The present invention solves the conventional problems by disposing a shape memory alloy in the hot air outlet for local drying disposed in the toilet seat device, so that it can be used for cold air and hot air. The purpose is to allow cold air to hit local areas by changing the direction of air flow.

Structure of the Invention In order to achieve this object, the present invention provides a discharge port that opens into the toilet bowl at the downstream end of the downstream side ventilation passage of an electric heater used for local drying, and forms an arcuate upper wall surface of the discharge port. A bias protrusion is provided on the lower wall surface opposite to the adhesion wall to form a ventilation path between the bias protrusion and the adhesion wall. A bias spring is disposed between the protrusion and the lower wall surface, so that the bias protrusion can be moved in the vertical direction.

According to the second configuration, the airflow discharged from the discharge port can be directed downward when the air is cold, and toward a local area when the air is warm.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to FIGS. 3 to 5. FIG. 3 is a partial cross-sectional view of the side surface of the device B disposed on the toilet bowl 11, and FIGS. 4 and 5 are cross-sectional views of the main parts thereof.

In Figs. 3 to 5, solid line arrows indicate the flow of hot air for local drying, and Figs. 3 and 4 show the flow of hot air when passing through, and Fig. 5 shows when cold air is passing through.

As shown in FIGS. 3 and 4, a blower for blowing warm air for local drying and an electric heater 19 for heating the air are arranged inside the external device 4 17, and downstream of the electric heater 19. The downstream end of the ventilation passage 15 is opened into the toilet bowl 11 and serves as a discharge port 12 for discharging hot water for local drying, and the discharge port 12u: The upper wall surface is formed in an arc shape to form an adhesion wall 13. A bias protrusion 14 is provided on the lower wall surface 16 facing this so as to have a ventilation passage 17 between it and the adhesion wall 13.

However, the bias protrusion 14 uses a shape memory alloy molded into a plate shape, and the bias protrusion 14 and the lower wall surface 1
6 is connected to the bias spring 2o through page 5, and the bias protrusion 14 is connected to the attachment wall 13 and the lower wall surface 1.
6 and is configured to be movable in the vertical direction.

In this configuration, when the air blown by the blower 18 passes through the electric heater 19, it is heated and becomes warm air at the discharge port 1.
2 into the toilet bowl 11 and used for drying the local area.

On the other hand, since the upper wall surface of the discharge port 12 is formed in an arc shape and a bias protrusion 14 is provided opposite thereto, the airflow flowing through the ventilation passage 15 is directed to the surface of the adhesion wall 13 due to the influence of the bias protrusion 14. flow along the discharge port 12
The direction of the air flow discharged from the arc is approximately tangential to the arc. That is, a clear flow is formed on the surface of the adhesion wall 13 due to the Coanda effect. However, the Coanda effect changes depending on the position of the bias protrusion 14. That is, when the bias protrusion 14 moves downward, the Coanda effect becomes weaker and the ejection direction changes downward.

Therefore, when the bias spring 20 moves the bias protrusion 14 downward as shown in FIG.
When the peso is used, cold air is discharged downward, and when the air is hot, the bias protrusion 14 is moved upward by the force of the shape memory alloy contracting, as shown in FIGS. 3 and 4, and hot air is discharged upward to localize It is used for drying.

Effects of the Invention According to the present invention, the upper wall surface of the discharge port is formed in an arc shape, and a bias protrusion is provided opposite to this, the bias protrusion is made of a shape memory alloy, and is movable in the vertical direction with a bias spring. Because of this structure, the Coanda effect can be changed depending on the temperature of the airflow passing through it. Therefore, when hot air is used, hot air is ejected in the local direction to help dry the local area, and when cold air is used, hot air is ejected downward to prevent the cold air from coming into contact with the user, creating a comfortable toilet seat device. This is something that can be provided.
