Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a household ozone deodorizer which is mainly used in household toilets to eliminate unpleasant odors from the toilets.

0002

BACKGROUND OF THE INVENTION In recent years, there has been an increasing need for deodorization in the home, and particularly in toilets and the like, there has been an increasing desire to remove bad odors after defecation as quickly as possible, and to leave the room odorless when entering the room.

Conventionally, this type of household ozone deodorizer is shown in FIG.
And as shown in FIG. 4a, a power supply battery 21 and a switch 2
2, a timer 23 for generating a signal for a certain period of time, a switched fan motor 24, an FET 25, an ozone generation circuit 26 for generating ozone, and an ozone discharge body 27.

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

First, the user presses the switch 22 when entering the toilet and defecating. The timer section 23 recognizes this and the FE
A signal is generated at T25 to rotate the fan motor 24, and at the same time, a signal is also generated to the ozone generation circuit 26, so that the ozone discharge body 27 generates ozone. After a certain period of time,
The timer section 23 overflows and stops the fan motor 24 and the ozone generation circuit.

[0006]

[Problems to be Solved by the Invention] However, in the conventional configuration described above, when the user operates a switch at any time, the fan motor rotates with the same capacity, generates ozone, and operates for the same amount of time. There was a problem in that the odor was not removed sufficiently during the morning peak hours, and the odor of people who had defecated earlier may remain. The present invention solves the above-mentioned conventional problems, and as shown in Fig. 4a, although there is a time lag in household toilets, the peak of the day's congestion is in the morning.
The odor is at its peak during this time. Therefore, by estimating the time period when the toilet is used frequently, the fan motor and ozone supply unit are automatically operated during that period regardless of switch operation, increasing the deodorizing ability according to the frequency of use, and ensuring that the toilet is always used. The purpose of this invention is to provide a household ozone deodorizer that makes ozone odorless.

[0007]

[Means for Solving the Problems] To achieve this object, the household ozone deodorizer of the present invention mainly includes a switch that is operated when the odor in the toilet is bothersome, and a frequency detector that detects the frequency of operation of the switch. a memory section that stores the time zone and a certain time zone, and a clock timer that measures the 24 hours a day.
The ozone supply unit consists of a fan motor that can rotate and stop, an ozone generation circuit that can generate and stop, and an ozone discharge body, and the fan motor and ozone supply based on information from the frequency detection unit, clock timer unit, and memory unit. and a control section that controls the control section.

[0008]

[Operation] With this configuration, the frequency of operation of the switch is detected, a certain calculation is performed to estimate the time period with high frequency, and the time period with high frequency is stored and stored in the memory section. In addition to operating the fan motor and the ozone supply unit at the same time, the fan motor and the ozone supply unit can also be operated automatically during the high-frequency time period, regardless of the operation of the switch. .

[0009]

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

In FIGS. 1 and 2, 1 is a battery for power supply, and 2 is an operation switch. 2 is a human body detection unit that detects when a user enters the toilet, and 3 is a human body detection unit that detects the frequency of the user by operating a switch from the human body detection unit 2 or entering the room, and determines the optimal performance and optimal operating time. 4 is a clock timer that measures 24 hours a day, 5 is a memory unit that stores a certain time period and operating capacity, and 6 is the frequency detector 3, the clock timer Part 4,
A control section inputs information from the memory section 5 and controls a fan motor 7 and an ozone supply section. 7 is a fan motor that sends air, and 8 controls the fan motor 7 according to a signal from the control section 6. 9 is an ozone discharge body that generates ozone, and 10 is an ozone generation circuit that drives the ozone discharge body 9 in response to a signal from the control section 6.

The operation of the household ozone deodorizer constructed as above will be explained below.

In the case of FIG. 1, the user enters the toilet and presses the operating switch 2. In the case of FIG. 2, when the user enters the toilet, the human body detection section 2 detects this. Figures 1 and 2 below
It is the same as The frequency detection unit 3 detects this and operates the fan motor 7 and the ozone supply unit for a certain period of time through the control unit 6 if they are not in operation. After that, each time several users enter the room, the usage time and usage frequency are measured, and the operating capacity and operating time are estimated using a membership function, etc., and the memory unit 5
to be memorized. Then, in the control 6, if the time measured by the timer 4 and the time stored in the memory section match, the fan motor 7 is automatically rotated through the FET 8 using the ability stored in the memory section. At the same time, ozone is generated from the ozone discharge body 9 through the ozone generation circuit 10.

As described above, according to this embodiment, the usage status of the toilet in the household is estimated based on the frequency of switch operation, as shown in FIG. 4b, and the rotation speed of the fan motor and the amount of ozone generated are automatically adjusted accordingly. can be determined and operated automatically.

[0014]

As described above, according to the present invention, as shown in FIG. 4b, the capacity of the fan motor and ozone generation circuit is automatically reduced during the peak usage period of each household, that is, the peak period of bad odor. By raising the temperature and operating the system, it is possible to quickly deodorize before the next person enters, and to maintain a constant state of bad odors.
