DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a household ozone deodorizer mainly used for household toilets and for eliminating unpleasant odors in the toilets.

[0002]

2. Description of the Related Art In recent years, there has been an increasing need for deodorization in homes, especially in toilets and the like.

Conventionally, this type of household ozone deodorizer is shown in FIG.
And a power supply battery 21 and a switch 2 as shown in FIG.
2, an ozone generating circuit 26 for generating ozone, and an ozone discharger 27.

[0004] The operation of the home ozone deodorizer configured as described above will be described below, taking as an example a case where it is installed in a toilet.

[0005] First, the user presses the switch 22 when entering the toilet and defecation. The timer unit 23 recognizes this, and
At the same time as generating a signal at T25 and rotating the fan motor 24, a signal is also generated at the ozone generation circuit 26 and ozone is generated by the ozone discharger 27. After a certain time,
The timer section 23 overflows and stops the fan motor 24 and the ozone generation circuit.

[0006]

However, in the above-mentioned conventional configuration, the fan motor rotates with the same ability when the user operates the switch in any time zone, generating ozone and operating for the same time. There is a problem that the odor is not sufficiently deodorized during the peak hours in the morning, and the odor of the person who defecates before that may remain. The present invention solves the above-mentioned conventional problems. As shown in FIG. 4A, although there is a time lag depending on the household in the home toilet, there is a peak of congestion of one day in the morning, and during that time, Odor peaks. Therefore, the time period during which the toilet is frequently used is estimated, and during that time, the fan motor and the ozone supply unit are automatically operated regardless of the switch operation, and the deodorizing ability is increased in accordance with the frequency of use,
It is an object of the present invention to provide a household ozone deodorizer that always makes a toilet odorless.

[0007]

According to the present invention, there is provided a household ozone deodorizer according to the present invention, comprising: a switch which is mainly operated when the odor of a toilet is worrisome; and a frequency detection which detects the frequency of operation of the switch. Unit and a memory unit for storing a fixed time zone, a clock timer for measuring 24 hours a day,
A fan motor capable of rotating and stopping, an ozone supply unit including an ozone generating circuit and an ozone discharger capable of generating and stopping, and a fan motor and ozone supply based on information from the frequency detection unit, the clock timer unit and the memory unit. And a control unit for controlling the unit.

[0008]

According to this structure, the frequency of operation of the switch is detected, a certain calculation is performed to estimate a time period of high frequency, and the time period is stored in the memory unit. It is possible to operate the fan motor and the ozone supply unit automatically, regardless of the operation of the switch, in addition to the operation of the fan motor and the ozone supply unit during the time period when the frequency is high. .

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. 1, 2 and 4b.

In FIGS. 1 and 2, reference numeral 1 denotes a power supply battery, and reference numeral 2 denotes an operation switch. Reference numeral 2 denotes a human body detection unit that detects that the user has entered the toilet. Reference numeral 3 denotes a frequency of the user by operating a switch from the human body detection unit 2 or entering the room to obtain an optimal capacity and an optimal operation time. 4 is a clock timer that measures 24 hours a day, 5 is a memory unit that stores a fixed time zone and operating capacity, 6 is the frequency detection unit 3, and a clock timer Part 4,
A control unit that inputs information of the memory unit 5 and controls a fan motor 7 and an ozone supply unit, 7 is a fan motor that sends air, and 8 is a fan unit that controls the fan motor 7 based on a signal from the control unit 6 A driving FET 9 is an ozone discharger that generates ozone, and 10 is an ozone generation circuit that drives the ozone discharger 9 based on a signal from the control unit 6.

The operation of the household ozone deodorizer configured as described above will be described below.

In the case of FIG. 1, the user enters the toilet and presses the operation switch 2. In the case of FIG. 2, when the user enters the toilet, the human body detection unit 2 detects this. Figures 1 and 2 below
And the same. The frequency detection unit 3 detects this, and operates the fan motor 7 and the ozone supply unit through the control unit 6 for a predetermined time unless the fan motor 7 and the ozone supply unit are operating. Thereafter, each time several users enter the room, the usage time and usage frequency are measured, and the operation capability and operation time are estimated using the membership function and the like.
To memorize. In the control 6, if the time measured by the timer 4 matches the time stored in the memory unit, the fan motor 7 is automatically rotated through the FET 8 with the capability stored in the memory unit. At the same time, ozone is generated from the ozone discharger 9 through the ozone generation circuit 10.

As described above, according to the present embodiment, as shown in FIG. 4B, the usage state of the toilet in the home is estimated based on the operation frequency of the switch, and the rotation speed of the fan motor and the ozone generation amount are automatically adjusted accordingly. Can be determined and automatically operated.

[0014]

As described above, according to the present invention, the capacity of the fan motor and the ozone generation circuit is automatically set during the peak usage period of each household, that is, the peak time period of the offensive odor, as shown in FIG. 4B. To deodorize quickly before the next person enters, and it is possible to always maintain a bad odor state.
