[0001]

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 provided with a deodorizing function for heating indoor toilets and eliminating odors during use.

[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. 6 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 multi-functionality, such a hot water flush toilet seat is provided with, for example, a hot air heating device 5 for heating the toilet and a deodorizing device 6 for eliminating the odor during the toilet. .

The hot air heating device 5 is housed in the casing 2 below the operation panel 2a, 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 opens to the bottom side of the casing 2,
For example, air is suctioned from an intake port opened at an appropriate place such as the back surface of the casing 2, and heated air is discharged from a discharge end after heating by a heater.

The deodorizing device 6 is housed in the casing 2 on the right side when viewed from the front, and is provided with a ball portion 1a of the toilet body 1.
The flow path is connected to a duct 7 which faces the suction unit. The casing 2 includes a fan for sucking air and a deodorizing unit using an ozonizer, a catalyst, or the like, and discharges deodorized air from the bottom surface of the casing 2.

[0007]

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.

In addition, when 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 heating device 4 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 port becomes smaller than the original opening area or the resistance of the surrounding equipment becomes larger, air is sucked from the outlet port 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.

On the other hand, the deodorizing device 6 sucks air containing odor from the ball portion 1a via the duct 7 by the operation thereof, and releases it after deodorizing. However, the hot-air heating device 5 sucks air from the outlet 2b regardless of the operation of the deodorant device 6 when the intake port is clogged or the like.
It is discharged as warm air without being deodorized.

As described above, when the warm air heating device 5 is incorporated in the casing 2, the warm air containing the unpleasant odor from the warm air heating device 5 is diffused in spite of the provision of the deodorizing device 6. Will be. Therefore, a person sitting on the toilet seat 3 is exposed to an odorous atmosphere, which is likely to cause discomfort.

The problem to be solved in the present invention is to enable sufficient deodorization by the deodorizing device and to suppress odor diffusion by the hot air heating device even when the hot air heating device is operating. .

[0016]

This invention SUMMARY OF THE INVENTION may, for casings grayed housing the electrical equipment, such as a part washing function a toilet seat device for fixing the toilet body, the interior of the casing, by sucking air from the outside with incorporation of the warm-air heating device for room heating to release hot air after heating, comprising a deodorizing device for removing odor and have suction air from the ball portion of the toilet main body, the front Symbol warm-air heating device is operating And a system for increasing the air suction force of the deodorizing device as compared with the time of steady operation.

An odor sensor for detecting the odor of the ball portion of the toilet body is provided. During the period of the odor detection by the odor sensor and during the operation of the warm air heating / heating device, the air suction force of the deodorizing device is reduced. It is also possible to make the system larger than that during steady operation.

[0018] Further, a dressing for detecting a person sitting on the toilet seat is provided.
A seat sensor is provided, and during the period of detection of a person by the seating sensor or the period of odor detection by the odor sensor, the air suction capability of the deodorizing device is increased and the air suction capability of the heating device is reduced or stopped. You may do so.

[0019]

The warm air heating device and the deodorizing device provided inside the casing are controlled so that the air is strongly drawn toward the deodorizing device on the basis of detection of a person sitting on the toilet seat or generation of odor. . For this reason, most of the air drawn from the bowl portion of the toilet body is sucked into the deodorizing device, the air containing the odor is deodorized, and the hot air heating device emits the hot air without the odor. . In addition, if the suction power of the hot air heating device is controlled to be lowered or stopped by detecting seating or odor, efficient deodorization by the deodorizing device becomes possible, and at the same time diffusion of odor by the hot air heating device. Is prevented.

1 is a partially cutaway left side view showing the outline of the toilet seat device of the present invention.

The toilet seat device comprises a casing 2 fixed to a toilet body 1, a toilet seat 3 and a toilet lid 4 in the same manner 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 heating device 5 has a blower fan 5c driven by a motor 5b built in a housing 5a and extends downstream from the blower fan 5c to the bottom side of the casing 2. The air from the blower fan 5c is heated by a heater. It is heated by 5d and can be released from the lower end. A temperature sensor 5e for detecting the temperature of the hot air is incorporated, and a controller 8 for controlling the number of rotations of the motor 5b of the blower fan 5c and the amount of electricity to the heater 5d in response to the signal is provided in the casing 2. . The operation panel 2a is provided with a heating switch 2e for operating the hot air heating device 5 and a stop switch 2f for stopping the heating switch.

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.

FIG. 2 is a partially cutaway right side view showing a main part of the toilet seat device.

A deodorizing device 6 is incorporated in the casing 2 at a portion that hangs down along the right side of the toilet body 1 when viewed from the front.

The deodorizing device 6 includes a housing 6a communicating with a duct 7 having an open end facing the ball portion 1a of the toilet body 1. The housing 6a has a shape facing the bottom side of the casing 2 and its lower end is opened to serve as a discharge port, and contains a scavenging fan 6c rotated by a motor 6b. The scavenging fan 6c
Ozonizer 6d and catalyst 6 are used to deodorize air sucked from ball 1a via duct 7 by rotation of
e respectively.

For example, the deodorizing device 6 automatically starts operating when a person sits on the toilet seat 3 and, after use, leaves the toilet seat 3 to some extent so that the odor is sufficiently removed. Is controlled by the controller 8 so as to stop automatically after the lapse of time. Instead of such an automatic operation, a deodorizing switch 2g is provided on the operation panel 2a.
Also, a deodorization stop switch 2h may be provided, and a manual operation using these switches may be performed.

Further, at a position where the casing 2 faces the ball portion of the toilet body 1, an odor sensor 9 is provided so as to be exposed to the ball portion side (see FIG. 1). As the odor sensor 9, an element using an element whose resistance value changes depending on the concentration of the odor can be used, and the presence or absence of the odor can be determined by inputting the change in the resistance value to the controller 8.

Here, the hot air heating device 5 and the deodorizing device 6
The operation of each is controlled by the controller 8 based on the detection of a person sitting or the detection of an odor. This control pattern is a period during which the seat sensor 3a detects that a person is sitting on the toilet seat 3 or a period during which the odor sensor 9 is detecting odor, and the warm air heating device 5 is operated. When the hot air heating device 5 is not operating, the suction capacity of the scavenging fan 6c of the deodorizing device 6 is made larger than when the hot air heating device 5 is not operating.

FIG. 3 is a flow chart for controlling the operation of the deodorizing device 6 based on a detection signal of a person by the seating sensor 3a.

In this flow, even if the heating switch 2e is turned on, if no person is seated, no signal is input from the seating sensor 3a, and the deodorizing device 6 does not operate. Further, even when the warm air heating device 5 is stopped when heating is not required, the deodorizing device 6 operates when a person sits down. The motor 6b of the deodorizing device 6 during the stop period of the hot air heating device 5
Is the steady value.

When the heating switch 2e is turned on,
When a person sits on the toilet seat 3 and the seating sensor 3a detects this, the motor 6b of the deodorizing device 6 is operated by the controller 8, and air is sucked from the ball portion 1a to start deodorizing. At this time, the output of the motor 6b is set to be larger than the steady value, and
Better than the air suction force of It is a matter of course that such control of the output of the motor 6b 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 described above, even when the hot air heating device 5 is operated, if a person sits on the toilet seat 3, the air suction force of the deodorizing device 6 becomes larger than the steady value only during that period, and preferably the hot air It is larger than that of the heating device 5. For this reason, the air containing an unpleasant odor in the stool is sucked from the duct 7 to the deodorizing device 6 side and deodorized, and the diffusion of the odor from the warm air heating device 5 is prevented.

FIG. 4 is a flowchart for controlling the operation of the deodorizing device 6 based on the detection of the odor by the odor sensor 9.

In this example, the deodorizing device 6 is controlled so that the suction force of the air becomes larger than the suction force of the hot air heating device 5 in operation from the time when the odor is generated by the stool. Therefore, the air containing the odor is sucked into the deodorizing device 6 at the time when the odor is generated, and the odor is not diffused even when the hot air heating device 5 is operated as in the previous case.

FIG. 5 shows that the output of the motor 6b of the deodorizing device 6 is increased from a steady value and the motor of the hot air heating device 5 while the person is sitting while the warm air heating device 5 is operating. 5 is a flowchart of control for lowering or stopping the output of FIG.

In this example, when a person sits on the toilet seat 3, the suction force of the deodorizing device 6 increases and the suction force of the warm air heating device 5 decreases or becomes zero. For this reason, the deodorization by the deodorizing device 6 is efficiently performed similarly to the previous example, and at the same time, the blowing of the warm air from the warm air heating device 5 is reduced, so that the diffusion of the odor is more effectively suppressed. . And if it is the control which stops the warm air heating apparatus 5, there is no odor diffusion at all,
A comfortable environment can be obtained.

Further, the control based on the detection of odor by the odor sensor 9 is completely the same as that described in parentheses in FIG. 5, instead of the control based on the seating of the person by the seat sensor 3a. .

Further, in the above-described control, the odor can be prevented from being diffused without stopping the operation of the warm air heating device 5, so that, for example, when the temperature is low, even if the user stays in the toilet for a long time, he or she feels cold. Therefore, an atmosphere having a temperature that is not too low even when used by the next person immediately can be obtained.

[0040]

According to the present invention, the suction of air to the deodorizing device side is increased even if the hot air heating device is operating, based on the detection of a person sitting on the toilet seat or the generation of odor. ,
The odor is reliably removed, the odor from the hot air heating device can be suppressed from spreading, and no discomfort is given to the user or the next user.

Further, if the suction force of the hot air heater is reduced or stopped in addition to the increase of the suction force of the deodorizing device, the suction of air to the deodorizing device side is promoted. At the same time, the emission from the hot air heater is small or zero,
Odor diffusion can be more effectively prevented.
