Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorizing device for a toilet bowl.

[0002]

2. Description of the Related Art Conventionally, there is a toilet bowl equipped with a deodorizing fan in order to remove the malodor generated in the toilet bowl to the outside, and this toilet bowl, when a toilet person sits on the toilet seat,
The seating sensor detects the seated state, and the deodorizing fan is turned on and off based on the signal from the seating sensor. However, for example, when men piss, they often do not sit on the toilet seat. In such cases, the seating sensor cannot detect the seated state, so the deodorizing fan does not operate and deodorization is not performed well. There was a problem.

[0003]

SUMMARY OF THE INVENTION The present invention has been devised in view of the above conventional problems, and an object thereof is to provide a deodorizing device capable of favorably performing deodorization in all cases, and the gist thereof is In a toilet equipped with a deodorizing fan capable of discharging a bad smell generated in the toilet to the outside, and having a toilet lid that can be opened and closed, the deodorizing fan is turned on based on opening and closing of the toilet lid,
That is, a control circuit for OFF control is provided.

[0004]

[Function] Since the deodorizing fan is turned on and off through the control circuit based on the opening and closing of the toilet lid, even when a man performs urination, the toilet lid is opened to activate the deodorizing fan. Can be deodorized.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an external perspective view of a toilet bowl with a deodorizing device, in which a toilet seat box 4 is fixedly provided on the upper rear portion of the toilet body 1, and the toilet seat box 4 is supported by the toilet seat box 4 so that it can be opened and closed. 3 is provided, and a low tank 6 for storing wash water is provided upright behind the toilet seat box 4. A seat sensor 5 is attached to the side of the toilet seat box 4 to detect that the toilet user is seated on the toilet seat 2.

FIG. 2 is a perspective view of the inside of the toilet seat box 4. A deodorizing duct 10 is provided in the toilet seat box 4, and a deodorizing fan 11 is incorporated in the deodorizing duct 10. The suction port 10a of 10 is opened to the toilet body 1 side, and the air outlet 10b of the deodorizing duct 10 is opened to the bottom side of the toilet seat box 4. A deodorizing cartridge 12 containing a deodorant is detachably attached to the outlet 10b. Further, in order to detect the open / closed state of the toilet lid 3, the toilet seat box 4 is provided with a toilet lid position sensor 8, which is connected to the shaft 3a of the toilet lid 3 as shown in the schematic view of FIG. If the detected body 9 made of, for example, a magnetic material is provided on the outer peripheral side of the toilet lid opening / closing gear 7, the toilet lid 3 is closed when the detected body 9 approaches the toilet lid position sensor 8. It is possible to detect that the toilet lid 3 has been opened, and to detect that the toilet lid 3 has been opened when the toilet lid position sensor 8 moves away from the detected body 9.

FIG. 4 is a block diagram of the periphery of a control circuit installed in the toilet seat box 4. The control circuit 13 includes a toilet lid position sensor 8 and a toilet seat position sensor 15 for detecting the open / closed state of the toilet seat 2. From the seat sensor 5 is also input. Also,
A fan drive circuit 14 for driving the deodorizing fan 11 is connected to the control circuit 13.

In the control circuit 13, the control shown in the flow chart of FIG. 5 is performed. That is, in S1 (step 1) in FIG. 5, it is determined whether or not the toilet lid 3 has been opened. That is, when it is confirmed that the toilet lid 3 is opened in the control circuit 13 based on the signal from the toilet lid position sensor 8, the fan driving circuit 14 outputs a signal to the fan driving circuit 14. Power is supplied to the deodorizing fan 11 to operate the deodorizing fan 11 in S2 (step 2). That is, the toilet lid 3 is opened not only when seated on the toilet seat 2 for urination, but also when a man urinates. In any case, the toilet lid 3 is opened during urination. The deodorizing fan 11 is operated when the lid 3 is opened, and the deodorizing fan 11 is operated in order to perform good deodorization under all kinds of fecal conditions.

Next, in S3 (step 3), the toilet lid 3
Is closed, that is, whether or not the stool has ended, and it is confirmed that the toilet lid 3 has been closed based on the signal from the toilet lid position sensor 8, and then the control circuit 13
The timer circuit therein determines whether or not, for example, 60 seconds have elapsed in S4 (step 4), but after 60 seconds have elapsed, the deodorizing fan 11 is stopped in S5 (step 5). That is, 6 after the toilet lid 3 is closed
The deodorizing fan 11 is continuously operated for 0 seconds to completely discharge the malodor in the toilet to the outside, and then the deodorizing fan 11
To stop. When seating on the toilet seat 2 for stool use, it is more reliable if the deodorizing fan 11 is controlled to be stopped based on both the 0FF signal from the seat sensor 5 and the closing signal from the toilet lid 3. Various operations can be performed.

INDUSTRIAL APPLICABILITY The present invention provides a toilet bowl equipped with a deodorizing fan capable of discharging a bad smell generated in the toilet to the outside and having a toilet lid that can be opened and closed. By providing a control circuit for ON / OFF control, the deodorizing fan did not operate in the past when the man was pissing, but the deodorizing fan always operates via the control circuit when the toilet lid is opened. , A deodorizing fan can always be operated favorably at any time of use, and a good deodorizing function can be exhibited.
