[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bubble-washing type toilet device for flushing dirt in a toilet bowl into a toilet bowl by bubbles of a cleaning liquid.
In particular, the present invention relates to a unit type bubble-wash toilet device in which a solar cell is used as a power source and a toilet bowl is provided in a toilet box.

[0002]

2. Description of the Related Art Conventionally, a non-washing facility is used in an area where the flush toilet cannot be installed because the sewer system has not been installed, or is temporarily installed and used as at a construction site. A variety of toilet devices such as a toilet type and a simple flush type are known. Among them, the bubble washing type toilet device that pushes the waste in the toilet bowl to the toilet tank with the foam of the cleaning liquid has a feeling of use and odor compared to other types of toilets such as a non-washing type and a circulation type that circulates wash water. In terms of the above, it is superior to the main washing type, but a power source is indispensable because the air pump of the foaming device needs to be operated.

[0003]

Therefore, in the conventional bubble-wash toilet device, in the mountains where commercial power cannot be supplied, it is necessary to secure a power source by a private power generator, etc. However, there is an inconvenience that it cannot be used when it is impossible. An object of the present invention is to provide a bubble-wash toilet device equipped with a solar cell, which eliminates such inconvenience and can withstand long-term non-sunlight by suppressing power consumption according to usage conditions. .

[0004]

In order to achieve the above-mentioned object, a bubble washing type toilet device of the present invention is a toilet box provided with a toilet bowl, a solar cell as a power source, and a predetermined output of this solar cell. When the value is equal to or more than the value, the surplus power is stored, and when it does not reach the predetermined value, the storage battery serving as a power source that replaces the solar cell, and the output of the solar cell has reached the predetermined value.
Solar cell output detection means for detecting whether or not it is, a foaming device for supplying foam of cleaning liquid to a toilet, and this foaming device is operated for flowing dirt, and the solar cell output detection
Means that the output of the solar cell has reached the predetermined value.
If it is detected that the value has not reached the specified value, it will operate intermittently at preset intervals.
In this case, a control circuit for controlling so as to stop the intermittent operation is provided. That is, in the case of this type bubble washing type toilet, in order to prevent the odor from rising from the toilet bowl, the bubbles are constantly discharged to the discharge port side to maintain the discharge port in a closed state. However, in the case of using a solar cell as a power source, considering the power consumption, this steady method cannot be adopted .
When the output has reached a predetermined value , the bubbles are intermittently discharged so that the closed state due to the bubbles in the discharge port is maintained .
If this does not reach the prescribed value, this intermittent outflow of bubbles
Is configured to stop .

In addition to the above-mentioned structure, a human sensor for detecting a user and a solar cell output detecting means for detecting whether the output of the solar cell has reached a predetermined voltage value are provided, and the control circuit is In addition to operating the foaming device for flowing dirt, it has an intermittent operation mode and a human operation mode, and in the intermittent operation mode, the foaming device is controlled to operate intermittently at a predetermined interval set in advance. In the human operation mode, when the detection signal from the human sensor is received, the foaming device is controlled to operate, and when the storage battery is operating as a power source, the output signal from the solar cell output detection means detects the human presence. It is configured to switch to the operation mode.

[0006]

When the output of the solar cell is higher than the predetermined voltage, the control circuit controls the operation of the foaming device by using this as a power source, and the dirt in the toilet bowl is flushed with the foam of the cleaning liquid into the toilet bowl and set in advance. It is operated intermittently at a predetermined interval, and bubbles are retained on the outlet side of the toilet bowl to prevent odors in the toilet bowl from entering the toilet box, and excess power is stored in the storage battery while the solar battery is used. If the output of does not reach the predetermined voltage, the above operation is performed using the storage battery as a power source. In addition, if a motion sensor is provided, the same operation as described above is performed in the intermittent operation mode. If the human operation mode is performed, the foaming device is operated only when the human sensor detects the user, and when the storage battery functions as a power source at night when the number of users is small,
Operates in human motion mode to reduce power consumption.

The outflow passage 5a guides the water to the outlet side and flows out into the bowl, and the foam of the cleaning liquid formed in the second foaming chamber 4e flows out into the bowl from the foam supply unit 4 side of the toilet 5 in the direction of the white arrow. Is configured to.

The above-mentioned air pumps 7a and 7b are housed in a housing portion 24 provided in an operation box 21 having a push button switch 20 on the front surface as shown in FIGS.
In the operation box 21, electric parts such as a substrate 25 provided with various switches and a control circuit 9 (see FIG. 4) are housed, and a lighting lamp 10 as a lighting tool and a door 2 are housed.
A human sensor 16 for detecting infrared rays emitted by a user who has opened the door and entered the toilet box 1 is provided corresponding to the transparent window 22. The connector portion in the operation box 21 is incorporated into a lead wire terminal 26 of the storage battery 11 arranged in the toilet box 1 and an exhaust pipe 12 standing outside the toilet box 1 so as to communicate with a toilet bowl. The terminal 27 of the lead wire of the exhaust fan 13 and the solar cell 15 fixed on the roof of the toilet box 1 via the frame 14.
The lead wire terminal 28 is connected. An air cleaner 29 for the air pumps 7a and 7b is provided on the upper surface of the storage portion 24. Further, the air pumps 7a, 7b, the illumination lamp 10, the human sensor 16, the exhaust fan 13, the storage battery 11, and the solar battery 15 are electrically connected to the control circuit 9, and the storage battery 11 is connected. Also, using the solar cell 15 as a power source, the control circuit 9 controls the air pumps 7a and 7b, the illumination lamp 10, and the odor-eliminating fan 1 based on signals from the human sensor 16 and various switches.
3 is controlled so that each operation is controlled. Reference numeral 17 in FIG. 1 denotes a large water supply tank, which can be attached to the outside of the toilet box 1 as a parent tank of the water supply tank 6 when the water in the water supply tank 6 is exhausted or without the water supply tank 6. It is used, and it is effective when there are many users or when the water supply interval is long.

Next, the configuration of the electric system centering on the control circuit 9 will be described in more detail with reference to FIG. 12V / 2
4W solar cell 15 and 12V / 38AH storage battery 11
Are connected via an overcharge / overdischarge prevention circuit 18. The overcharge / overdischarge prevention circuit 18 is provided for the storage battery 1
When 1 is in a state close to overcharge (a terminal voltage is 14.7 V or higher), the charging current from the solar cell 15 is cut off, while the storage battery 11 is in a state close to overdischarge (terminal voltage). Is below 10.5 V), the supply circuit to the load is cut off, the power supply to the load is stopped, all the generated current of the solar cell 15 is charged, and the terminal voltage returns to 12 V. It is configured to start power supply to each load again. Further, since the outputs of the solar cell 15 and the storage battery 11 are DC 0 to 16V, a regulator 19 for adjusting the output to DC 5V which is the operating voltage of the control circuit 9 is provided.

The day / night detection circuit 23, which is the solar cell output detection means to which the output of the solar cell 15 is added, is the solar cell 1
It discriminates day and night based on the output voltage value of 5. If the voltage value is 10V or more, it is detected as daytime and nighttime when 10V is not reached, and the detection signal is detected by the intermittent ON / OFF timer circuit 92 and the inverter 103. Output to. The intermittent ON / OF that operates when this detection signal is a daytime detection signal
The F timer circuit 92 controls the operation time of the first air pump 7a together with the timer circuit 93 that operates when the detection signal of the human sensor 16 is input. These both circuits 92 and 93 are provided in the operation box 21. It is connected to the first air pump control circuit 95 through a changeover switch 94 that selectively switches between the intermittent operation mode and the human operation mode by a knob (not shown) arranged. The timer circuit 93 is also connected to the first air pump control circuit 96, which is the same as the first air pump control circuit 95, without passing through the changeover switch 94.

The setting of the ON / OFF time in the intermittent ON / OFF timer circuit 92 is performed by an intermittent ON time setting volume and an intermittent OFF time setting volume (both not shown) arranged in the operation box 21. Normally, the ON time is set to 60 seconds and the OFF time is set to 10 minutes. This time setting is determined based on the experimental result regarding the residence time of the foam flowing out from the outlet side in the bowl in the vicinity of the outlet. Here, the state in which the foam flowing out from the outlet side of the toilet bowl 5 at a speed of about 20% at the time of cleaning almost spreads to the bowl wall surface on the outlet side and completely closed the outlet is defined as 100% foam occupancy. Gradually disappears and remains only in the vicinity of the outlet of the toilet 5 and maintains the closed state of the outlet as a bubble occupancy rate of 50%, and when the outlet is open, the bubble occupancy rate is 50%. If it is less than 50%, a bubble occupancy rate of 50% or more is required to prevent odor from the toilet bowl. According to an experiment conducted by the present inventors, when the temperature is 20 ° C., as shown in FIG.
About 2 minutes after the air pump 7a is turned on, the bubble occupancy rate reaches 100%, where the first air pump 7 is
When a is turned off, the bubble occupancy rate is 50% after about 10 minutes.
The result is that It was also confirmed that when the temperature is low, the bubble occupancy rate gradually decreases, and as the temperature rises, it suddenly decreases. Therefore, when the temperature is higher than 20 ° C, the OFF time is shortened to less than 10 minutes, and when the temperature is lower than 20 ° C, the OFF time is set to 1
It is preferable to extend the time longer than 0 minutes. By the intermittent operation of the first air pump 7a, the outlet of the toilet bowl 5 is always closed by bubbles, and the odor in the toilet bowl is prevented from entering the toilet box 1. Similarly, the timer circuit 93, which operates when the detection signal of the human sensor 16 is input, is normally set to 60 seconds.

Each first air pump control circuit 9
Reference numerals 5 and 96 are the first to determine the outflow rate of the foam based on the set value of the control volume arranged in the operation box 21.
The air volume of the air pump 7a is set by adjusting the lengths of ON time and OFF time. Specifically, the first air pump 7a is set within the operating time set by the timer circuits 92 and 93 described above. When the air volume is set to the minimum, the ON time is 0.5 ms and the OFF time is 9.5 ms, and when the air volume is set to the medium level, the ON time is 5 ms and the OFF time is 5 ms. Works with
When air volume is set to maximum, ON time is 9ms, OFF
It operates on a cycle of 1 ms in time and can be adjusted within a minimum and maximum range. The output end of the first air pump control circuit 95 is connected to one input end of the OR circuit 101, and the other input end of the OR circuit 101 is turned on by the push button switch 20 provided on the front surface of the operation box 21. It is connected to the output terminal of the circuit 97.

On the other hand, the output terminal of the first air pump control circuit 96 is connected to one input terminal of the AND circuit 102, and the other input terminal of the AND circuit 102 outputs the output of the day / night detection circuit 23 via the inverter 103. Connected to the end. Then, the OR circuit 101 and the AND circuit 1
Each output terminal of 02 is connected to each input terminal of the OR circuit 104, and the output of the OR circuit 104 is configured to be input to the first air pump 7a via the FET.
The output of the timer circuit 97 is the OR circuit 101.
Input to the second air pump 7b via FET
Is configured to be input. Therefore, the first
The air pump 7a and the second air pump 7b are connected to the timer circuit 9 when the push button switch 20 is turned on.
It operates for the time set in 7. The outflow of bubbles by the push button switch 20 is for cleaning filth, and the ON time in the timer circuit 97 is normally set to 40 seconds, and about 200 cc of bubbles are outflowed.

The output terminal of the motion sensor 16 is connected to the timer circuit 93 via the inverter 105, and also connected to one input terminal of the OR circuit 107 and one input terminal of the AND circuit 108 via the inverter 106. It is connected to the. The other input terminal of the OR circuit 107 is provided with a knob (not shown) arranged in the operation box 21 for continuous operation of the operation of the odor eliminating fan 13 and a sensing operation of operating only when a user is sensed. It is connected to the output terminal of the day / night detection circuit 23 via a changeover switch 98 that selectively switches to and the two inverters 109 and 103. The other input end of the AND circuit 108 is connected to the output end of the inverter 103, while the output of the AND circuit 108 is input to the illumination lamp 10 via the FET. Further, the OR circuit 10
The output of 7 is input to the exhaust fan 13 via the FET.

Next, the operation of the toilet device described above will be described. First, as shown in FIG. 4, a normal operation will be described in which the changeover switch 94 is set to the intermittent operation mode (state indicated by the solid line) and the changeover switch 98 is set to the continuous operation mode (state indicated by the solid line). In the daytime, when the solar cell 15 operates normally and outputs a voltage of 10 V or higher, the day / night detection circuit 23 outputs a daytime detection signal,
The intermittent ON / OFF timer circuit 92 and the first air pump control circuit 95 are in the operating state, and the output is O.
Since the R circuits 101 and 104 are sequentially turned on and sent as an ON signal to the first air pump 7a, the first air pump 7a is intermittently ON / OFF timer circuit 92.
The bubbling operation is performed according to the air volume set by the first air pump control circuit 95 every predetermined time set by, and the bubbles of the cleaning liquid flow from the first bubbling chamber 4d to the outlet side of the toilet 5 according to the air volume. It flows out at a constant speed and stays near the discharge port. This foam keeps the dirt discharged near the discharge port of the toilet bowl 5 difficult to adhere to at all times and keeps the inside of the toilet bowl 5 and the toilet bowl side in a closed state to prevent the odor in the toilet bowl from rising. Block. On the other hand, the daytime detection signal output of the day / night detection circuit 23 is inverted twice by the two inverters 103 and 109 and input to the OR circuit 107 as an ON signal. Therefore, as long as this daytime detection signal is output, the exhaust fan 13 continues to operate, exhausts the odor in the toilet bowl to the outside, and in addition to the above-mentioned blocking state by the staying bubbles, further prevents the rise of the odor.

In this state, when the human sensor 16 senses that the user has entered the toilet box 1, the ON signal from the inverter 105 causes the timer circuit 93,
The first air pump control circuit 96 is activated, an ON signal is sent to one input terminal of the AND circuit 102, and an ON signal is sent via the inverter 106 to turn the signal ON.
The ON signal is also sent to each one input terminal of the R circuit 107 and the AND circuit 108. Here, each of the AND circuits 10
No. 2 and No. 108 output no output signal because the ON signal is not sent to the other input end of them.
The first air pump 7a does not operate and the illumination lamp 10 does not light unless the operation time set by the OFF timer circuit 92 is reached. On the other hand, the exhaust fan 13 continues to operate regardless of the presence or absence of the sensing signal. When the user presses the push button switch 20 after use, the ON signal is sent to one input end of the OR circuit 101 and the second air pump 7b via the timer circuit 97. As a result, the two air pumps 7a and 7b are operated for a predetermined time set by the timer circuit 97, and the bubbles of the cleaning liquid are discharged from the first foaming chamber 4d and the second foaming chamber 2e to the discharge port side in the toilet 5 respectively. It flows out to the side of the supply unit 4 and pushes the waste into the toilet tank.

On the other hand, in the daytime, the respective changeover switches 94, 9
When the operation mode 8 is switched to the human operation mode (state shown by phantom lines), the operation differs from the operation described above with respect to the first air pump 7
Intermittent ON / OFF timer circuit 92 controls a.
Instead, it is performed by the timer circuit 93. Therefore, unless the human sensor 16 detects the user, the air pumps 7a and 7b do not operate. When the human sensor 16 outputs a detection signal, the timer circuit 93, each first air pump control circuit, 9
5, 96 are in an operating state, an ON signal is sent to one input terminal of the OR circuit 101, the OR circuit 104 is also in an ON state, and the first air pump 7a is operated by the timer circuit 93.
The ON operation is performed for the predetermined time set in step 3, and the bubbles of the cleaning liquid flow out from the outlet side of the toilet 5 before the toilet so that dirt is not easily attached. When the push button switch 20 is pressed after the toilet has been operated, the air pumps 7a and 7b are operated in the same manner as described above, so that the bubbles of the cleaning liquid flow out into the toilet bowl 5 and the dirt is pushed into the toilet bowl. In addition, when the changeover switch 98 is switched to the human motion mode, the input from the day / night detection circuit 23 to the OR circuit 107 is lost, and only when the human sensor 16 outputs the detection signal, this is an ON signal. It is input to the OR circuit 107, and the exhaust fan 13 is operated. As described above, the human motion mode in the daytime is effective when the number of users is small and consumes less power.

Next, the operation at night or in the rain will be described with reference to FIG. Since the solar battery 15 does not generate power at night or in rainy weather, the storage battery 11 serves as a power source, while the nighttime detection signal is output from the day / night detection circuit 23, so the intermittent ON / OFF timer circuit 92 does not operate, and Since the ON signal is not input to the OR circuit 107, the human operation mode is set regardless of the state of the changeover switches 94 and 98. Then, the AND circuit 108
The night detection signal of the day / night detection circuit 23 is inverted by the inverter 103 and input as an ON signal to one of the input terminals. Now, when the motion sensor 16 senses the user, the timer circuit 93 operates and the O
An ON signal is input to one of the input terminals of the R circuit 107 and the AND circuit 108, the odor eliminating fan 13 is activated, and the illumination lamp 10 is turned on.

When the changeover switch 94 is in the intermittent operation mode, the first air pump control circuit 9
Since only 6 is in the operating state, the ON signal is input to one input terminal of the AND circuit 102, and the ON signal is input to the other input terminal of the AND circuit 102 via the inverter 103. 102 to OR circuit 1
An ON signal is input to one input terminal of 04. On the other hand, when the changeover switch 94 is in the human operation mode, the first air pump control circuits 95 and 96 are in the operating state, both the OR circuit 101 and the AND circuit 102 are in the ON state, and both the OR circuits 104 are in the ON state. O at the input end of
N signal is input. Therefore, regardless of the state of the changeover switch 94, the first air pump 7a
Is turned on for a predetermined time set by the timer circuit 93, and the bubbles of the cleaning liquid flow out from the outlet side of the toilet 5 before the toilet, so that dirt is unlikely to adhere. When the push button switch 20 is pressed after the toilet has been operated, the air pumps 7a and 7b are operated in the same manner as in the daytime, and the bubbles of the cleaning liquid flow out into the toilet bowl 5 to push the dirt into the toilet bowl. When the human sensor 16 stops outputting the detection signal, the odor eliminating fan 13
Stops and the illumination lamp 10 is also turned off. As described above, at night when the solar cell 15 does not generate power, the human-operated operation mode is automatically set to minimize power consumption.

The present invention is not limited to the above-described embodiment, and for example, the large water supply tank 17 may not be provided.
Further, the storage battery 11 can be arranged outside the toilet box 1. Further, it goes without saying that the shape of the toilet bowl 5 is not limited to the so-called Japanese type shown in the figure, and may be a Western type. Furthermore, the human sensor 16, the exhaust fan 13, and the illumination lamp 10 are not always necessary depending on the application, and the configuration of the control circuit 9 is not limited to the above.

[0022]

As is apparent from the above description, according to the present invention, the use of a solar cell as a power source while maintaining the usability and deodorization of the bubble-wash toilet device can be utilized. expanding the range and moved is facilitated, further, with a combination of storage battery as a power source, a solar cell foam behavior foaming device performs for deodorizing by a control circuit
When the control circuit has an intermittent operation mode and a human operation mode, in addition, when the solar cell cannot generate power at night, the human operation is performed. By controlling the operation by switching to the mode and only when the user is present, there is an effect that the power consumption by the foaming device can be minimized and the good operation can be continued even in long-term non-sunlight.
