However, when a person is no longer detected after a certain period of time, a signal from the sensor circuit can automatically spray the deodorant, the fragrance, and the germicide in the tank. And

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a toilet deodorant, a fragrance, and a bactericide generating device for removing a bad odor in a toilet or mitigating it by aroma.

[0002]

[Prior Art]

 Generally, in the toilet, immediately after people use the toilet, there is a bad odor in the toilet, and the next person to enter the toilet feels very uncomfortable. Therefore, in the past, chemicals that generate fragrance were placed in the toilet, but this can only have a calming effect. In addition, although it is possible to generate aroma in the toilet and mitigate the foul odor by spraying, it is not effective even if the next person sprays the spray, and it is not effective after the toilet is used. Humans tend to forget to apply a spray, so little effect can be expected.

[0003]

[Problems to be solved by the device]

 This invention was made with this point in mind, and when a person leaves the toilet after using the toilet, the deodorant, fragrance, and bactericide are automatically sprayed, which may cause harmful effects in the toilet. It is an object of the present invention to provide a deodorant, fragrance, and bactericide generator that can remove odor substantially completely.

[0004]

[Means for Solving the Problems]

 The configuration of the present invention for the above purpose comprises a sensor that operates by confirming the presence of a person, and a tank containing a deodorant and / or a fragrance, and the sensor confirms the presence of a person. However, if a person is no longer detected after a certain period of time, a signal from the sensor circuit can automatically spray the deodorant, the fragrance, and the germicide in the tank. Characterize.

Embodiments Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the device of the present invention, and 2 is a human detection sensor, which is configured to detect the presence of a human 1 in a toilet and output a detection signal. A photoelectric sensor can be used as the human detection sensor unit 2. When a human enters the detection area of the toilet, the human detection sensor unit 2 outputs a pulsed detection signal and outputs it to the control circuit 4. The control circuit 4 is composed of a control circuit and a drive circuit having a well-known microcomputer, and is equipped with various operating elements such as a timer measuring volume and a switch. It is connected to a nozzle drive unit 7 that drives a nozzle 8 that sprays a germicide, a timer circuit 6 that measures a preset time, and a human sensor 2. The control circuit 4 functions as a 24-hour timer, a counter, and the like, and energizes the drive unit 7 that drives the nozzle 8 based on the operation status of the operator of the operation device 5 and the detection signal output by the human detection sensor 2, The timing of automatically spraying deodorants, fragrances and germicides is controlled.

When the sensing signal enters the control circuit 4 and the human sensing sensor 2 detects that there is no human being after a preset time has passed, the nozzle driving unit is activated based on the sensing signal. , The deodorant, the fragrance, and the germicide are automatically sprayed from the nozzle 8 for a preset period of time. After spraying the deodorant, fragrance and germicide, the device of the present invention returns to the initial state. The nozzle drive unit 7 has a motor and a pump driven by the motor, and the suction port of the pump is connected to the deodorant, the fragrance and the germicide in the tank 9 by a hose, and the discharge port of the pump. Are connected to the nozzle 8. The specific configuration of each of the above-mentioned components is the same as that of the urinal cleaning device that automatically controls the cleaning of the urinal according to the usage condition, and details are described in, for example, Japanese Patent Laid-Open No. 60-250136. It is described in. If the deodorant, fragrance, and bactericide contained in the tank are liquid, it is possible to use known deodorizers for human waste, fragrances and neutralizers for neutralizing the bad smell of the toilet. good. Deodorants, fragrances and germicides are preferably used in combination together, but they may be used alone.

[0007]

[Action]

 Next, the operation of the present invention constructed as described above will be described with reference to FIGS. In FIG. 2, when a power switch (not shown) is turned on, the start 11 state is set, and the control circuit 4 resets the timer 6 and waits for the user to enter the toilet and turn on the sensor. The state of setting 12 is set. When the person 1 enters the toilet, the sensor 1 detects the person 1 13 and the timer 6 measures the usage time t 14. When a person 1 comes out of the toilet, the usage time t is determined, and when this value exceeds 15 which is a preset time T, a signal is sent to the nozzle drive unit 7 16. By this signal, the motor of the drive unit 7 is turned on, the motor rotates, and the pump is driven. Then, the deodorant, fragrance, and bactericide in the tank 9 are sucked through the hose from the suction port of the pump, and are pumped to the nozzle 8 from the discharge port of the pump. Fragrance and germicide are sprayed in the toilet for a certain period of time. Therefore, people who enter the toilet later do not feel the bad odor caused by the stools of the people in front. When the preset time has elapsed, the device of the present invention returns to the initial initial setting 12 state.

[0008]

【effect】

 As described above, according to the present invention, the deodorant, the fragrance and the bactericide are automatically sprayed into the toilet after human beings use it, so that the odor in the toilet can be substantially eliminated. Since it can be removed and sterilized, the toilet can be used in a comfortable and clean condition at any time.
