BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet seat provided in a toilet body, and more particularly to a toilet seat device having a function of heating the interior of a toilet.

[0002]

2. Description of the Related Art A warm water flush toilet seat having a hot water flush function has been conventionally used as a toilet seat provided in a toilet body. This hot water flush toilet seat has been multifunctionalized not only with a flushing function but also with, for example, indoor heating and deodorization.

FIG. 5 is a view showing an example of a warm water flush toilet seat. A toilet seat 3 and a toilet lid 4 are attached to a casing 2 fixed on a toilet body 1 so as to be openable and closable. The casing 2 is provided with an operation panel 2a for a person sitting on the toilet seat 3 to operate, and the operation panel 2a performs operations such as operation of a washing nozzle 2b which can be advanced and retracted from the casing 2 and heating of the toilet seat 3.

[0004] As an example of multifunctionalization of such a hot water flush toilet seat, a hot air heating device 5 for heating the toilet is used.
Is incorporated. The warm air heating device 5 is housed in a casing 2 below an operation panel 2a located on a side of the toilet body 1, and includes a blower fan, a heater, a temperature sensor, and the like. Then, the warm air discharge end of the warm air heating device 5 is opened on the bottom surface side of the casing 2.
Air is suctioned from an intake port opened at an appropriate place such as the back surface of the device, and warm air is discharged from a discharge end after heating by a heater.

[0005]

In order to prevent foreign substances from entering the casing 2 and to prevent the internal electrical components from being wetted, the intake port opened in the casing 2 is provided with, for example, an array of elongated slits or small holes. It is easy to be limited to what can be opened. For this reason, if the hot-air heating device 5 is constantly operated, dust and the like easily adhere to the slits and small holes.

[0006] In addition, in the case where the intake port becomes very close to the wall or the pipe of the toilet due to the arrangement posture or the like of the toilet body 1 in the toilet, the resistance when air is taken in from the intake port becomes large. Become.

As described above, when the adhesion of the dust and the resistance due to the surrounding equipment increase, when the fan of the hot air heater 5 is operated, an amount of air corresponding to the suction capacity cannot be taken in from the suction port. An airflow that covers the insufficient air from other places easily occurs inside the casing 2.

On the other hand, as a portion where the casing 2 opens to the outside, there is an opening 2c serving as a passage when the washing nozzle 2b moves. The recess 2c is formed by opening a lower portion on the front side of the casing 2 and the cleaning nozzle 2c.
It has a size that does not interfere with the operation of b.

Therefore, when the intake opening becomes smaller than the original opening area or the resistance of the surrounding equipment becomes larger, air is sucked from the outlet 2c, and is heated and discharged by the hot air heating device 5. You.

However, since the opening / closing port 2c is open facing the ball portion of the toilet body 1, air containing odor is sucked when the toilet is used. Therefore, the odorous hot air is released from the hot air heating device 5,
Offensive odor diffuses in the toilet.

As described above, when the air cannot be sufficiently sucked from the intake port, the warm air heating device 5 is operated to create an odorous atmosphere, giving a user discomfort.

The problem to be solved in the present invention is to suppress the spread of off-flavors when using a hot-air heating device, and to maintain a comfortable environment in the toilet.

[0013]

SUMMARY OF THE INVENTION The present invention is directed to a casing housing electrical components such as a local cleaning function, a toilet seat openably and closably mounted on the casing, and a seating sensor for detecting a person sitting on the toilet seat. A toilet seat device with a built-in warm air heating device for indoor heating, which inside the casing, sucks air from the outside and emits hot air after heating,
A controller is provided for stopping the operation of the warm air heating device or reducing the air volume during the period of detecting the seating of the person by the seating sensor.

In addition, an odor sensor for detecting the odor of the bowl portion of the toilet body is provided in place of the seating sensor, and the operation of the hot air heating device is similarly stopped or the air volume is reduced during the odor detection by the odor sensor. A configuration for performing control may be adopted.

[0015]

The warm air heating device provided in the casing detects that a person is sitting on the toilet seat by a seating sensor or an odor sensor detects an odor even when the device is in operation.
Control is performed so as to stop the operation or reduce the air volume.

When the operation of the warm air heating device is stopped, the suction and release of air are stopped, so that the suction of the unpleasant odor from the ball portion side of the toilet bowl is stopped, and the diffusion of the odor is prevented.

Further, even when the air volume is controlled to be small, the suction of the off-flavor from the ball portion side is weakened, and the output of the warm air to the outside is also weakened. For this reason, as in the case of the operation stoppage, the diffusion of the unpleasant odor is suppressed, and the heating itself is not interrupted, so that a rapid temperature drop in the toilet does not occur.

[0018]

FIG. 1 is a side view showing an outline of a toilet seat device of the present invention.

The toilet seat device is composed of a casing 2 fixed to a toilet body 1, a toilet seat 3 and a toilet lid 4 as shown in FIG. Similarly, the hot air heating device 5 is incorporated in the casing 2 located below the operation panel 2a, and a slit-shaped air hole 2d is provided at the bottom of the casing 2.

The hot air heater 5 has a blower fan 5c driven by a motor 5b inside a housing 5a and extends downstream from the blower fan 5c to the bottom side of the casing 2 so that air from the blower fan 5c is heated by a heater. It is heated by 5d and can be released from the lower end. Then, a temperature sensor 5e for detecting the temperature of the hot air is incorporated, and in response to the signal, the number of rotations of the motor 5b of the blower fan 5c and the amount of electricity to the heater 5d are controlled, and also all other devices are controlled. Is provided in the casing 2. The operation panel 2a has a heating switch 2e for operating the hot air heating device 5 and a stop switch 2f for stopping the heating.
Are provided.

On the other hand, the toilet seat 3 is provided with a detection system for detecting the seating of a person. In the illustrated example, the toilet seat 3 is provided with a pressure-sensitive seat sensor 3a incorporated in the toilet seat 3. This seating sensor 3a
Is an on / off type in which a detection signal is input to the controller 6 according to a load when a person sits on the toilet seat 3 and there is no output signal when no person is seated. In addition, instead of such a pressure-sensitive type, a reflection type or transmission type photoelectric switch using infrared rays or the like incorporated on the front side of the casing 2 can be used.

Further, at a position where the casing 2 faces the ball portion of the toilet body 1, the odor sensor 7 is exposed to the ball portion side and incorporated. As the odor sensor 7, a sensor using an element whose resistance value changes depending on the concentration of the odor can be used. By inputting the change in the resistance value to the controller 6, the presence or absence of the odor can be determined.

The warm air heating device 5 is used for seating a person on the toilet seat 3,
The operation is controlled in accordance with the non-seated state and the odor detection state by the odor sensor 7, and a heating pattern for preventing the spread of an odor at the time of use is executed. And
Such a pattern may be a control to stop the operation of the hot air heating device 5 during a period in which a person is sitting or a period in which the odor sensor 7 is detecting an odor, and a case where the air volume is lower than that in the normal operation. Can also be applied.

FIG. 2 is a flowchart of the former pattern.

In this flow, when the heating switch 2e is turned on, a signal is not input from the seating sensor 3a and a person is not seated, or unless the odor sensor 7 detects odor, The heating device 5 is turned on and continues to operate. And when heating is unnecessary, the stop switch 2
The warm air heating device 5 can be stopped by the operation of f.

On the other hand, when the heating switch 2e is turned on, when a person sits on the toilet seat 3 and the seating sensor 3a detects it or the odor sensor 7 detects odor, the warm air heating device 5
Is not activated without being turned on. Then, when the person separates from the toilet seat 3 and the seat sensor 3a is turned off or the odor sensor 7 stops detecting the odor, the warm air heating device 5 starts operating again to perform heating.

As described above, even when the warm air heating device 5 is operated, if a person sits on the toilet seat 3 or an odor is detected, the operation of the warm air heating device 5 is stopped only during that period. For this reason, the rotation of the blower fan 5c by the motor 5b is also stopped, and even if the air hole 2c is clogged with dust, the air is not sucked through the opening / closing port of the cleaning nozzle 2b. Therefore, the air containing the unpleasant odor accompanying the stool is not heated and released from the warm air heating device 5.

FIG. 3 is a flow chart showing a flow of suppressing the air volume by reducing the rotation speed of the motor 5b during a period in which a person is sitting or an odor is detected.

Also in this flow, during a period in which no person is seated on the toilet seat 3 or a period in which no odor is detected, the hot air heating device 5 continues to operate as in the previous example. The operation is stopped by 2f. And
When the seating sensor 3a detects that a person is sitting on the toilet seat 3 when the heating switch 2e is on or the odor sensor 7 detects odor, the controller 6 controls the motor 5b to reduce the rotation speed.

It is a matter of course that such control of the number of revolutions can be performed by changing the voltage if the motor 5b is a DC type, and by changing the frequency if the motor 5b is an AC type.

As the number of revolutions of the motor 5b decreases, the amount of air blown by the blower fan 5c also decreases, and the discharge power becomes weaker than during normal operation. For this reason, during a period in which a person is sitting on the toilet seat 3 or a period in which an odor is detected, the hot air heating device 5 continues its operation, but the amount of air suction from the opening 2c due to the small amount of air blown. Not only is reduced, but also the amount of diffusion is suppressed. Therefore, the degree of filling of air containing an unpleasant odor at the time of stool becomes small, and a comfortable use environment is maintained.

When the seating sensor 3a detects that the person has left the toilet seat 3 or when the odor sensor 7 does not detect the odor, the controller 6 controls the rotation speed of the motor 5b to return to a steady value. Return to normal operation.

As described above, the odor sensor 7 detects the odor in comparison with the control of the operation of the warm air heating device 5 depending on whether or not a person is seated on the toilet seat 3.
In the apparatus that controls the operation of (1), since there is no odor, the warm air heating device 5 does not needlessly stop, so that the odor diffusion can be more efficiently prevented while heating is performed.

2 and 3 according to the temperature in the toilet.
The control can be made by fusing the above flow.

For example, when the temperature is relatively high, there is no rapid temperature drop even when the heating is turned off, so the flow of FIG. 2 is executed. When the temperature is low, the heating capacity decreases, but there is no temporary interruption.
Is executed. For such control, a temperature sensor for sensing the air temperature may be newly provided, and the controller 6 may execute any one of the above-described flows according to the detected temperature.

By the fusion of such control, the heating can be interrupted and the continuation under low power can be performed according to the temperature condition. For example, if the flow shown in FIG. 3 is used when the temperature is low, the user does not feel cold even if he stays in the toilet for a long time, and can create an atmosphere with a temperature that is not too low even when used immediately by the next person. .

Here, the control of the room temperature by the hot air heating device 5 includes a temperature sensor 5e for detecting the temperature of the blown hot air.
Alternatively, the room temperature can be detected and the hot air heating device 5 can be turned on and off.

FIG. 4 is a diagram showing the incorporation of the room temperature sensor 8 for detecting the room temperature, as viewed from the front side of the casing 2.

A booth 2g is formed on the right side of the casing 2 in which the warm air heating device 5 is disposed on the left side when viewed from the front, and is open to the outer lower surface at a position deflected to the rear side. A room temperature sensor 8 is incorporated therein. The booth 2g is located on the right side of the toilet body 1, and the room temperature sensor 8 is easily exposed to the outside air. Then, by inputting the room temperature detection signal from the room temperature sensor 8 to the controller 6, it is possible to control the ON / OFF of the hot air heater 5 and the amount of heat generated by the heater 5d to maintain a comfortable room temperature.

With such an arrangement of the room temperature sensor 8, it is possible to directly detect the outside air temperature instead of detecting the temperature of the air accumulated in the casing 2. For this reason,
It is possible to detect the room temperature equal to the sensible temperature felt by the user, and it is possible to appropriately and easily control the room temperature. In addition, since the booth 2g is only opened downward on the back side of the casing 2, the built-in equipment is prevented from being wet. Further, since the room temperature sensor 8 is located on the opposite side of the toilet body 1 with respect to the warm air heating device 5, it is possible to detect a circulated and steady outside air temperature after being discharged, thereby achieving more optimal room heating. Can be

[Effect of the Invention] In the present invention, the operation of the warm air heater is stopped or the amount of air is suppressed during a period in which a person is sitting on the toilet seat or a period in which odor is generated by the toilet, so that the air holes are dusty. There is no emission or diffusion of air containing off-flavors, even if it is clogged with air or the resistance is large due to surrounding equipment.
For this reason, the user does not feel discomfort due to the smell, and if only the amount of air blow is suppressed, a comfortable environment that is in a heating state and has no odor can be provided for the user who uses later.
