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 configuration and its problems Traditionally, this type of device has two configurations as shown in Figure 1.
A ventilation passage 5 is formed within the exterior 4 by providing a discharge port 2 that opens inside the toilet bowl 1 and an air supply port 3 that opens outside the toilet bowl 1, and an impeller 6 within the ventilation passage 5. A drying device A is provided which includes a built-in blower 8 and an electric heater 9, including a motor 7 that drives the air blower 8 and an electric heater 9.

This drying device A is placed behind the upper 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 a to the discharge port 2 (indicated by the solid 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 the toilet room, for example, an independent heater such as a hot air heater Jt is used.

were used together.

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

OBJECT OF THE INVENTION The present invention solves the problems of the conventional toilet seat system by heating the inside of the toilet room using a blower for local drying and an electric heater arranged in the toilet seat system. The purpose of this is to increase the
- Structure of the Invention In order to achieve this object, the present invention provides a heating path that opens to the outside of the toilet bowl via a heating hot air outlet on the downstream side of an electric heater used for local drying, and a drying hot air outlet. A drying path that opens into the toilet bowl through an outlet is provided, a damper is provided to open and close the heating path and the drying path using a shape memory alloy, and the drying path is driven by heating with an auxiliary heater. Memory alloy is arranged.

According to the above configuration, by using the blower and electric heater used for local drying, hot air can be discharged to the outside of the toilet bowl via the heating hot air discharge [ ], thereby heating the toilet bowl.

DESCRIPTION OF THE EMBODIMENTS The case where indoor heating is performed by opening the passage 15 will be shown.
Figure 3 shows its main parts. FIG. 4 similarly shows a state in which the heating path 15 is closed for the main part. Furthermore, the second
In the figures to FIG. 4, 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 FIGS. 2 to 4, a blower 18 for blowing hot air for room heating and an electric heater 19 for heating the air are arranged inside the external device 4, and the external device is located downstream of the electric heater 19. A heating path 15 is opened to the outside of the toilet bowl 11 through a heating warm air discharge 1125 provided at 4, and a heating path 15 is opened to the inside of the toilet bowl 11 through a drying ff1A air discharge port 12 that discharges hot air for drying when drying a local area. A drying path 13 is provided, and the heating path 15 is provided.
and the drying path 13 can be alternately opened and closed by an abbreviated damper 16 rotated by a coiled shape memory alloy 21 driven by an auxiliary heater 17 and an auxiliary coil spring 23.
Auxiliary heater 1 with a damper 16 disposed within the drying path 13
By applying current to 7, the coiled shape memory alloy 21
There are 5 pages with a configuration that drives the .

That is, the damper 16 is horizontally rotatable about the support column 22, and as shown in FIGS. 2 and 3, when the local area is dry, the damper 16 conducts electricity to the electric heater 19, blower 18, and auxiliary heater 17, and the auxiliary heater 170 generates heat. , the shape memory alloy 21 is driven to open the drying path 13, and at the same time, the heating path 15 is closed and used for drying the local area. On the other hand, during heating, the energization to the auxiliary heater 17 and the electric heater 19 is stopped, the coiled shape memory alloy 21 is cooled, the drying path 13 is closed by the auxiliary coil spring 23, and then the electric heater 19 is energized. Indoors.

It is configured to be used for heating. Further, the coiled shape memory alloy 21 is placed in the drying path 13 so that it is always in contact with hot air for drying, and the temperature of the hot air detected by the temperature sensor 20 placed near the shape memory alloy 21 is determined by the shape memory. When the operating temperature of the alloy 21 is reached, the auxiliary heater 17
After the power supply to the auxiliary heater 17 is stopped, the heat of the hot drying air is used to maintain the state of the coiled shape memory composite 6' and the metal 21 in the state when the power is applied. I try to do that.

With the above configuration, the air blown to the blower 18 is heated by the electric heater 19, and is directly discharged from the heating path 15 to the outside of the toilet bowl 11 via the heating hot air outlet 25 to heat the room. Ru.

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 drying path and heating path are opened and closed by a shape memory alloy that is driven by energizing the auxiliary heater and using the heat generated.When heating the room, the heating path is opened and communicated directly with the outside of the toilet, allowing the blower to The supplied air can be heated by an electric heater, and then directly discharged from the heating hot air outlet to the outside of the toilet bowl to heat the room.
