Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a toilet deodorizing device for removing odors generated in a toilet, and more particularly, to a toilet deodorizing device that controls the amount of exhaust air according to the operation of a hot air drying device or a hot water washing device.
[0002]
[Prior art]
A toilet deodorizing apparatus that sucks and exhausts odor-containing air in a bowl portion of a toilet has already been widely used. In order to improve the deodorizing effect of this toilet deodorizing device, it is known that a human body in a toilet room is detected by a sensor and a deodorizing fan is started when the proximity of the human body to the toilet is detected (Japanese Patent Laid-Open No. 8-218468). ).
[0003]
In addition, in order to strongly deodorize the odor of the person who was previously used and to prevent the user from feeling uncomfortable, when the human body detection sensor enters the human body detection state, the intake air of the deodorizing fan When the seating detection sensor enters the human body seating detection state, the air intake amount of the deodorizing fan becomes the normal air intake amount, and the seating detection sensor enters the human body non-seating detection state. A toilet deodorizing device is known in which the intake air amount of the deodorizing fan increases from the normal intake air amount (Japanese Patent Laid-Open No. 11-200454).
[0004]
There has also been proposed a toilet deodorization device that detects the odor concentration in the toilet bowl or the exhaust passage and increases the exhaust air volume when the odor concentration increases (Japanese Patent Laid-Open No. 2001-107419).
[0005]
[Problems to be solved by the invention]
In order to reduce the odor diffusing from the toilet bowl, it is preferable to increase the exhaust air volume as much as possible. However, by doing so, a feeling of cooling is felt in the seated buttock, and the feeling of use (comfort) of the toilet bowl is impaired.
[0006]
An object of this invention is to suppress the cooling sensation sensed by a buttocks at the time of operation of a toilet deodorizing apparatus. It is another object of the present invention to provide a toilet deodorizing device that has little odor diffusion from the toilet and that also suppresses the feeling of cooling in the buttocks.
[0007]
[Means for Solving the Problems]
The toilet deodorization apparatus of the present invention (Claim 1) is a toilet deodorization apparatus that discharges air in the toilet to the outside of the toilet by an exhaust fan, and operates the exhaust fan when seating is detected by a seating sensor that detects seating of a human body. And a control means for controlling so as to reduce the exhaust air volume of the exhaust fan when the hot water washing apparatus for washing the human body with warm water is operated.
[0008]
According to such a toilet deodorizing device, the amount of exhaust air when the human body part is wet by the hot water washing device is reduced, so that the cooling sensation due to the heat of vaporization of water can be reduced.
[0009]
The toilet deodorization apparatus according to the present invention (Claim 2) is characterized in that, in Claim 1, the control means is controlled so as to increase the exhaust air volume of the exhaust fan when the warm air drying apparatus that dries the human body with warm air is operated. It is characterized by doing.
[0010]
According to such a toilet deodorizing apparatus, the exhaust air volume is increased when the buttock is warmed by the operation of the hot air drying apparatus, so that the cooling sensation felt with the increase in the exhaust air volume is alleviated or eliminated. Odor diffusion is suppressed by increasing the exhaust air volume. Although the odor is strong and easily spread when the hot air drying device is operated, the odor is sufficiently suppressed by increasing the amount of deodorizing air.
[0011]
In this case, the exhaust air volume of the exhaust fan remains unchanged or is further reduced until the hot air drying device starts operating even after the hot water cleaning device stops operating, and the exhaust fan exhaust air volume increases when the hot air drying device operates. It is preferable to make it. If it does in this way, the cool feeling sensed by the heat of vaporization until the operation start of the warm air drying device is suppressed.
[0012]
When the warm air drying device is operated, the heel portion is warmed by the warm air, so that the cool feeling is suppressed even if the exhaust air volume is increased. Moreover, odor diffusion is suppressed by the increase in the exhaust air volume.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view of a toilet deodorizing apparatus according to an embodiment, FIG. 2 is a block diagram of the toilet deodorizing apparatus, and FIGS. 3 and 4 are timing charts showing an operation example of the toilet deodorizing apparatus. In FIG. 1, a part of the toilet seat box 3 is shown in a transparent state.
[0014]
As shown in FIG. 1, a toilet seat box 3 is installed on the rear upper surface of a toilet bowl 2 of a Western-style toilet 1, and a toilet seat and a toilet lid (both not shown) are attached to the toilet seat box 3 so as to be rotatable in the vertical direction.
[0015]
This toilet seat box 3 has a warm water tank 4, a shower nozzle 5 and a charm nozzle (bide nozzle) 6 to which warm water is supplied from the warm water tank 4, and a fan and an air heater for blowing warm air toward the buttock. In addition to the fan 7, the deodorizing cartridge 8 and the exhaust fan (deodorizing fan) 9 provided in the exhaust passage communicating the inside of the toilet bowl 2 and the outside of the toilet bowl 2, a control device 11 for controlling the operation of these devices (FIG. 2). ) Is provided. The deodorizing cartridge 8 is a cartridge in which activated carbon is accommodated in a bowl-shaped casing, but it is apparent that a deodorizing device having another configuration may be used.
[0016]
Although the low tank 10 is installed on the rear side of the toilet seat box 3, the low tank 10 may be omitted. In recent years, toilet bowls with a low tank have been rapidly spreading.
[0017]
The toilet seat box 3 is provided with an overhanging portion 3a that protrudes to the side, and various operation switches are provided on the upper surface of the overhanging portion 3a. The operation switches are provided on a remote controller (not shown). Also good.
[0018]
The operation switch includes at least a shower switch for irrigation, a bidet switch for bidet (hereinafter, the shower switch and bidet switch are hereinafter referred to as a washing switch) 12, a drying switch for operating a hot air fan 13. A stop switch 14 for stopping the hot water washing apparatus and the hot air drying operation is provided. Signals from these switches 12, 13, and 14 are input to the control device 11. The control device 11 also receives a signal from the seating sensor 15. As the seating sensor 15, various types of sensors such as a sensor that detects a seated person by infrared rays, ultrasonic waves, or the like are used in addition to a capacitive sensor that detects that a person is seated on the toilet seat by a change in electrostatic capacity. Can do.
[0019]
In addition to the hot air fan 7 and the exhaust fan 9, the control device 11 controls a cleaning device 16 including a pump and a valve that supply hot water from the hot water tank 4 to the shower nozzle 5 or the bidet nozzle 6.
[0020]
A reference example of the operation of the toilet deodorizing apparatus configured as described above will be described with reference to FIG.
[0021]
When the user is seated on the toilet seat, the seating sensor 15 outputs a seating signal, and the control device 11 starts rotating the exhaust fan 9 at a steady rotational speed. Even if an odor is generated along with defecation, the odor is adsorbed by the deodorizing cartridge 8 and the deodorized air is discharged from the exhaust fan 9. Thereafter, when the drying switch 13 is turned on, the control device 11 activates the hot air fan 7, increases the rotational speed of the exhaust fan 9, and increases the amount of exhaust air. Thereby, although the amount of exhaust air increases, since warm air is blown to the buttocks by the warm air fan 7, it is possible to suppress the user from feeling cold on the buttocks.
[0022]
Thereafter, when the drying switch 13 is turned OFF, the hot air fan 7 is stopped and the exhaust fan 9 is returned to the steady rotational speed. Thereby, the cooling sensation sensed by the buttocks is suppressed. Thereafter, when the user leaves the seat, the exhaust fan 9 stops. In FIG. 3, when the drying switch 13 is not turned on, the exhaust fan 9 is kept at a steady rotational speed from the seating to the seating.
[0023]
Referring to FIG. 4 will be described actual施例the operation of the toilet deodorizer.
[0024]
As the user sits on the toilet seat, the control device 11 operates the exhaust fan 9 at medium speed. Thereafter, when the cleaning switch 12 is turned ON, the control device 11 operates the cleaning device 16 to supply hot water to the nozzle 5 or 6. This warm water is poured into the buttock to wash the buttock and wet the buttock. Since the cooling sensation becomes stronger due to the heat of vaporization when the buttock gets wet, in this embodiment, when the cleaning switch 12 is turned on, the exhaust fan 9 is rotated at a low speed to reduce the exhaust air volume. Thereafter, when the drying switch 13 is turned on, the hot air fan 7 is operated and the exhaust fan 9 is rotated at a high speed to increase the amount of exhaust air.
[0025]
Thereafter, when the drying switch 13 is turned off, the exhaust fan 9 is returned to the medium speed rotation, and the exhaust fan 9 is stopped by being separated.
[0026]
In FIG. 4, when the drying switch 13 is not turned ON, the exhaust fan is kept rotating at a low speed after the cleaning switch is turned ON, and the exhaust fan 9 is stopped with the seating away.
[0027]
In this way, when the buttock is wet and the warm air fan 7 is not operating, the cooling air feeling can be remarkably reduced by reducing the amount of exhaust air. Moreover, since the amount of exhaust air is increased when the warm air fan 7 is operated and the warm air is blown to the buttocks, deodorization can be performed strongly.
[0028]
In the embodiment of FIG. 4, the constant air volume is set between the cleaning switch ON and the drying switch ON, but the air volume between the cleaning switch OFF and the drying switch ON is less than the air volume between the cleaning switch ON and the cleaning switch OFF. May be. This is because while warm water is being poured, there is a warm sensation of warm water, but after the warm water stops, the sensation of cooling due to vaporization heat tends to freeze on the skin until the warm air blows out.
[0029]
In the embodiment of FIG. 4 , the exhaust fan 9 is started with the seating, but when the entrance to the toilet room or the approach of the human body to the toilet is detected, the exhaust fan 9 may be started prior to the seating. Good. Further, the exhaust fan 9 may be operated for a predetermined time (or until the detected odor of the odor sensor becomes equal to or lower than a predetermined level) even after the person leaves.
[0030]
3 and 4, when the drying switch 13 is turned on, the speed of the exhaust fan 9 may be increased immediately, or the speed of the exhaust fan 9 may be increased slightly later. Further, when the drying switch 13 is turned off, the exhaust fan 9 may be decelerated immediately or may be decelerated slightly later.
[0031]
In the present invention, when performing the above control, the rotational speed of the exhaust fan may be adjusted according to the atmospheric humidity. Alternatively, the skin surface humidity of the buttocks may be detected by a sensor, and the rotational speed of the exhaust fan may be adjusted according to the skin surface humidity. Further, an odor sensor may be provided to adjust the rotational speed of the exhaust fan according to the odor intensity.
[0032]
The above embodiment is an example of the present invention, and the present invention may adopt a configuration other than the above. For example, the rotation speed of the ventilation fan in the toilet room as well as the deodorizing fan 8 may be controlled according to the detected concentration of the odor sensor 10. Further, when the odor concentration is higher than the predetermined concentration, the flash valve device may be driven. Further, each exhaust air volume may be changed according to the season, temperature, and time.
[0033]
【The invention's effect】
As described above, according to the toilet deodorizing apparatus of the present invention, it is possible to suppress the cooling sensation felt by the buttocks during the toilet deodorizing operation.
