Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a deodorizing device.

[0002]

[Prior Art]

 Conventionally, a deodorizer is attached to a toilet bowl to deodorize odors. There are various types of this deodorizing device, but generally, an intake port is provided so as to face the toilet bowl, and the odor in the toilet bowl is sucked through this intake port by the operation of the fan, and this is either used as it is or deodorized. After that, it is discharged from a predetermined discharge part.

In this deodorizing device, in order to perform deodorizing operation even after the toilet user normally leaves the toilet, the fan is still operated at the same rotation speed for a certain period of time (for example, about 1 minute). I am trying.

[0004]

[Problems to be solved by the device]

 However, even if the toilet user leaves the toilet bowl and continues to perform the deodorizing action, the odor often remains. In this case, there is a problem that the next user feels uncomfortable especially in public toilets.

However, if the amount of intake air is increased by, for example, increasing the rotation of the fan from the time of using the toilet, the deodorizing effect can be enhanced so that the next user does not leave an odor or uses the odor. It can be less.

However, when the amount of intake air from the intake port is increased, the flow of air around the intake port, that is, the air around the buttocks of the toilet user becomes stronger, and the user feels a draft feeling, which is uncomfortable for the toilet user. Cause a pleasant sensation.

[0007] The limit air volume (intake volume) is set to 0.15 m ³ / min. Therefore, in the conventional case, the operation of the fan during and after using the toilet is set to be less than the above air volume. It is the actual situation that has been done.

[0008]

[Means for Solving the Problems]

 The invention of the present application has been made to solve such a problem. Thus, the invention of the present application is directed to a deodorizing device that deodorizes a human body by a human body detection sensor by deodorizing the odor by inhaling the odor from an intake port provided to face the toilet bowl by the inhaling means and discharging the odor. The inhaler is configured such that the amount of intake air from the intake port increases when the human body detection sensor changes from the human body detection state to the non-detection state (claim 1).

Another invention of the present application is based on human body detection by a human body detection sensor, thereby performing deodorization by inhaling odor with an inhalation means from an intake port provided so as to face a toilet bowl and discharging it from an exhaust section. In the deodorizing device, an odor sensor for detecting odor is provided, and when the human body detection sensor changes from a human body detection state to a non-detection state and the odor sensor detects odor, the intake amount from the intake port increases. The inhaler is configured in the above (Claim 2).

[0010]

[Action and effect of the device]

 According to the invention of claim 1, the amount of intake air that has been constant even after the user has left the toilet bowl (after leaving the toilet) while the user is using the toilet bowl is increased after the sitting.

In this way, the generated odor is quickly deodorized without causing the user to feel a sense of draft or discomfort while using the toilet bowl, and the odor is not left to the person who next uses the toilet bowl. Or the residual odor can be effectively reduced.

According to the second aspect of the invention, when the toilet user leaves the toilet bowl and the odor remains, the intake amount is increased. It is possible to perform deodorization. In this case, it is possible to increase the intake air amount based on the strength of odor detection by the odor sensor.

【Example】

 Next, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 shows an example of a deodorizing device. This deodorizing device is provided with an intake port 10 provided so as to face the inside of a toilet bowl 12, a guide passage 14 for guiding the flow of inhaled odor, and a guide passage. It has a photocatalyst 16 provided on the photocatalyst 14, an ultraviolet lamp 18 for irradiating the photocatalyst 16 with ultraviolet rays, a fan 20 and an exhaust port 22 arranged at the end of the guide passage 14.

In this deodorizing device, the odor generated inside the toilet bowl 12 is sucked from the intake port 10 by the operation of the fan 20, flows through the guide passage 14, and is provided on the guide passage 14. 16 is passed.

At this time, the odorous components are adsorbed by the photocatalyst 16 and further decomposed under the irradiation of ultraviolet rays from the ultraviolet lamp 18. That is, the odor is deodorized in the process of being sucked from the intake port 10 and flowing through the guide passage 14, and is discharged from the end exhaust port 22 by the exhaust fan 20 in a state without odor.

The deodorizing device has a seating sensor 26 that detects when a toilet user sits on the toilet bowl, and a control unit 24 that controls the operation of the fan 20.

When the seating sensor 26 detects a human body, the control unit 24 rotates the fan 20 at a predetermined number of revolutions (air volume is, for example, 0.15 m ³ / min or less), and the fan is operated when the user leaves the seat. The number of revolutions of 20 is increased to increase the amount of intake air, and this is continued for a certain period of time (for example, 1 minute after the seat is separated).

The deodorizing apparatus of this example suppresses the rotation of the fan 20, that is, the amount of intake air from the intake port 10 to a relatively low value while the user is sitting on the toilet bowl to give the user a draft feeling. While not letting the user feel, after the user leaves the toilet bowl, the user strongly inhales the odor to deodorize. Therefore, no odor is left for the next toilet user, or residual odor is reduced and no unpleasant sensation is caused.

The above is an example in which the operation of the fan 20 is controlled based on the human body detection by the seating sensor 26. However, an odor sensor is provided and the operation of the fan 20 is controlled based on the signals from the seating sensor 26 and the odor sensor. It is also possible to control.

Specifically, the rotation of the fan 20 may be increased when the odor sensor detects an odor at the time when the sitting sensor 26 changes from the human body detection state to the non-detection state.

FIG. 2 shows a flow chart of the control in this case, in which the seating sensor 26 detects the seating of the human body on the toilet bowl and, at the same time, rotates the fan 20 (steps 28, 30) and uses it. If the odor sensor detects an odor when a person leaves the seat, the fan 20 is stopped after increasing the rotation speed of the fan 20 to increase the air volume and maintaining this for a certain time (1 minute). (Steps 32 to 38).

With this configuration, it is possible to efficiently perform deodorization after the toilet user has left the seat, depending on whether or not odor remains. In this case, it is also possible to change the rotation speed of the fan 20 according to the amount of residual odor.

FIG. 3 shows another example of the deodorizing device of the present invention. In the deodorizing device of this example, an intake port 40 is provided so as to face the inside of the toilet bowl 12, and after the odor is sucked from here, The fan 44 disposed inside the low tank 42 circulates the sucked odor through the duct 46 inside the low tank 42 and the duct 48 disposed outside the duct 46, and then discharges it to the outside through the discharge pipe 50.

Reference numeral 52 denotes a control unit that controls the rotation of the fan 44, and the control content thereof is basically the same as that of the above embodiment.

The embodiment of the present invention has been described in detail above, but this is merely an example, and the present invention can be applied to a deodorizing device for deodorizing by adsorption by activated carbon and various other deodorizing devices. However, the position of the intake port can be changed appropriately, and various modifications can be made based on the knowledge of those skilled in the art without departing from the spirit of the invention.
