Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a toilet seat device used in a Western-style toilet bowl, etc., which 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 heating the inside of the toilet. It is something.

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 includes a blower 8 and an electric heater 9, each of which includes an impeller 6 and a motor 7 for driving the impeller 6.

This drying device A is arranged at the upper rear part of the toilet bowl 1, and by energizing the electric heater 9 and operating the blower 8, air flows from the air supply port 3 to the discharge port 2 (indicated by the solid line arrow in the figure). ) was heated with an electric heater 9 and then discharged into the toilet bowl 1 from the discharge port 2 to dry the private parts. On the other hand, for heating inside the toilet, a separate heating device such as an air heater was used in combination.

However, although such a configuration has the advantage that each device can be used independently, there is a problem in that the entire device becomes large in size when used as a device having all functions.

OBJECTS OF THE INVENTION The present invention solves the conventional problems by heating the toilet room using a blower for local drying and an electric heater installed in the toilet seat device. The purpose is to make it more compact.

Structure of the Invention In order to achieve this object, the present invention provides a ventilation passage downstream of an electric heater used for local drying with a ventilation port that opens to the outside of the toilet bowl and a discharge port that opens into the toilet bowl. A damper is provided that opens and closes the ventilation port and the discharge port using a shape memory alloy driven by an auxiliary heater.

According to the above configuration, hot air in the ventilation path can be discharged to the outside of the toilet bowl through the ventilation opening by using the blower and electric heater used for drying the local area.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to FIGS. 2 to 4.

FIG. 2 shows a case in which the device B is placed on the toilet bowl 1 and the ventilation opening 13 is opened to heat the room, and FIG. 3 shows the main parts thereof. FIG. 4 similarly shows a state in which the main parts are closed with the ventilation holes 13 closed. In addition, Figures 2 to 4
In the figure, solid line arrows indicate the flow of hot air for indoor heating, and dashed-dotted line arrows indicate the flow of hot air for local drying.

As shown in Figures 2 to 4, a blower 18 for blowing hot air for indoor heating and an electric heater 19 for heating the air are arranged inside the external device 4, and are installed downstream of the electric heater 19. The ventilation passage 16 is provided with a ventilation port 13 that opens to the outside of the toilet bowl 11, and a discharge port 12 that opens into the toilet bowl 11 and discharges warm air for drying when drying a local area. A damper 16 is provided, and this damper 16 is driven by a coil-shaped shape memory alloy 21 having an auxiliary heater 20 disposed outside the ventilation port 13,
3 are configured to open and close alternately.

That is, the damper 16 provided at the ventilation hole 13
The inner end 23 rotates inward to the ventilation passage 15, and the outer end 24 rotates inward to the ventilation passage 16.
It has a structure that rotates outward, and as shown in FIGS. 2 and 3, when heating the room, the electric heater 19, the blower 18, and the auxiliary heater 20 are energized, and the heat generated by the auxiliary heater 20 drives the shape memory metal 21. At the same time as opening the ventilation port 13, the outlet 12 side of the ventilation path 16 is closed, so that the outside of the toilet bowl 11 and the ventilation path 15 are directly connected, and when the air flow from the blower 18 passes through the electric heater 19, it becomes warm air and is heated outside. The heating hot air is supplied into the room from a heating hot air outlet 25 provided in the device 4. On the other hand, the auxiliary heater 20 is a coiled shape memory alloy 2
The coil-shaped shape memory alloy 21 is placed inside the air vent 13 and is placed in the flow path of indoor heating hot air outside the ventilation opening 13, so that the ventilation opening 13 is opened and the indoor heating hot air flows. In this state, the power supply to the auxiliary heater 20 is stopped, and after the power supply to the auxiliary heater 20 is stopped, the state of the coiled shape memory alloy 21 is changed to the state when the current is applied by using the heat of the warm air for room heating. I try to keep up with the times.

When heating the room is stopped, the power supply to the auxiliary heater 20 and the electric heater 19 is stopped, so that the coiled shape memory alloy 21 becomes in a cold state, and as shown in FIG. The ventilation passage 15 is configured to be open on the discharge port 12 side.

With the above configuration, the air blown by the blower 18 is heated by the electric heater 19, and is directly discharged from the ventilation port 13 to the outside of the toilet bowl 11 via the heating hot air outlet 26 to heat the room.

Although the case where the auxiliary heater 20 is placed inside the coiled shape memory alloy 21 has been described, it goes without saying that the same effect can be obtained even if the auxiliary heater 20 is placed outside the coiled shape memory alloy 21.

Effects of the Invention According to the present invention, since the toilet room is heated using a blower for local drying and an electric heater, the entire device can be downsized. In addition, the configuration uses a shape memory alloy driven by an auxiliary heater to open and close the ventilation openings and discharge openings, and when heating the room, the ventilation openings are opened to directly communicate the outside of the toilet bowl with the ventilation passages, allowing the air blown by the blower to It is heated by the electric heater and discharged directly outside the toilet bowl from the ventilation opening to heat the room.When the ventilation opening is open, the power to the auxiliary heater is stopped and the open state is maintained using the heat of the hot air. , the damper opening/closing mechanism can be downsized.
