Hereinafter, embodiments of the present invention will be described. In addition, the same elements are designated by the same reference numerals throughout the present embodiment.

(First Embodiment of the present invention)
The bio-toilet system according to this embodiment will be described with reference to FIGS. 1 to 5. The bio-toilet system according to the present embodiment is a circulation type bio-toilet system that can be reused as cleaning water by treating the water used for cleaning the toilet with microorganisms. The required energy may be a completely independent circulating bio-toilet system that can function independently by using natural energy such as sunlight.

FIG. 1 is a schematic diagram showing a configuration of a bio-toilet system according to the present embodiment. The bio-toilet system 1 is the first by aerobic bacteria while storing the raw water tank 3 that physically decomposes the filth washed with water from the toilet 2 and the treated water 31 to be treated including the fine filth. The first adjusting tank 4 for aerobic treatment, the septic tank 5 for performing the first anaerobic treatment with anaerobic bacteria and the second aerobic treatment with aerobic bacteria, and the septic tank 5 treated water are stored. A second adjusting tank 6 that performs anaerobic treatment with anaerobic bacteria, a reaction tank 7 that decomposes organic substances contained in the water to be treated into carbon dioxide and water, and a washing tank 8 that stores treated water purified as reclaimed water. And a control unit 100 having a control device 101 that monitors and controls the entire system, a blower 102 that sends air to an air diffuser tube arranged in each tank, and the like.

The bio-toilet system 1 may include a solar panel that converts energy obtained from sunlight into electricity, and a secondary battery that charges the generated electricity.

First, the water to be treated 31, which is a mixture of the washing water used for washing in the toilet 2 and filth such as excrement, is put into the raw water tank 3. In the raw water tank 3, the solid matter contained in the charged water to be treated 31 is finely decomposed by aeration treatment through an aeration pipe 38 with air sent from the blower 102, and is sent to the next tank by a pump 33. The drive control of the pump 33 at this time is performed by the control unit 100.

In the raw water tank 3, the solid matter in the water to be treated 31 may be finely decomposed by the rotation of the stirring blade (not shown) together with the aeration treatment from the blower 102 through the air diffuser 38. At this time, the rotation control of the stirring blade may be performed by the control unit 100.

FIG. 2 is a diagram showing the structure of the raw water tank. The raw water tank 3 is sent out from the blower 102 by a charging area 32 into which the water to be treated 31 is charged, a delivery area 34 in which the water to be treated 31 in which solid matter is finely decomposed is sent to the next tank, and an aeration pipe 38. It has a buffer area 35 for performing aeration treatment with air.

Between the charging area 32 and the buffer area 35, a partition plate 39a for stopping and holding the solid matter contained in the water to be treated 31 charged from the toilet 2 is arranged in the charging area 32. The partition plate 39a is formed in a stepped shape from the end surface of the charging region 32 toward the central portion of the raw water tank 3. That is, as shown in FIG. 2, the partition plate 39a has a first member 392a extending in the horizontal direction from a position lower than the center of the end surface 391a of the charging region 32, and the first member 392a toward the center of the raw water tank 3. It is composed of a second member 393a extending diagonally upward, a third member 394a extending horizontally from the second member 393a, and a fourth member 395a extending vertically from the third member 394a. A relatively large volume is secured in the upper portion of the first member 392a, and a process of finely decomposing solid matter is performed mainly by aeration treatment from the air diffuser pipe 38 of the buffer region 35.

A small hole is formed in the first member 392a of the partition plate 39a, and the solid matter and the water to be treated 31, which are crushed into small pieces in the charging area 32, are circulated to the buffer area 35 through the hole. Solids that are not sufficiently crushed cannot be caught in the holes and moved to the buffer region 35 side. That is, the partition plate 39 serves as a filter, and by preventing solids that are not sufficiently crushed from coming out of the charging area 32, clogging of the pump 33 and the piping is prevented.

The buffer area 35 and the transmission area 34 are partitioned by a partition plate 39b. The partition plate 39b is arranged perpendicular to the bottom surface of the raw water tank 3, and is arranged at a predetermined distance from the fourth member 395a of the partition plate 39a. The reason for arranging the fourth member 395a at a predetermined distance is that even if the hole of the first member 392a is closed and the water to be treated 31 in the charging region 32 overflows, the water to be treated 31 is included. This is to prevent the solid matter from flowing to the delivery area 34. That is, even if the hole of the first member 392a is closed, the solid matter contained in the water to be treated 31 can be stopped in the buffer region 35 covered by the aeration treatment from the air diffuser pipe 38, and the pump 33 and the piping can be stopped. It is possible to reliably prevent clogging due to solid matter.

In the above process, since the aeration process is performed on the hole of the first member 392a from the buffer region 35 side opposite to the charging direction, it is considered extremely unlikely that all the holes of the first member 392a will be closed. However, the structure is such that the overflow of the input area 32 can be dealt with in case of emergency.

The height of the partition plate 39b is lower than the highest position of the fourth member 395a, and the structure is such that the water to be treated 31 overflowing in the buffer region 35 flows to the delivery region 34. That is, the treated water 31 flowing from the toilet 2 is charged into the charging area 32, and the increased capacity of the treated water 31 overflows from the buffer area 35 to the sending area 34 beyond the partition plate 39b. It has become. At this time, the solid matter contained in the water to be treated 31 is finely crushed in the charging region 32, and even if the hole of the first member 392a is closed, the buffer region 35 is used. Since the solid matter is finely crushed, the water to be treated 31 overflowing to the delivery region 34 beyond the partition plate 39b contains only the finely crushed solid matter. As a result, clogging of the pump 33 and the piping is surely prevented.

Further, as described above, the aeration pipe 38 for discharging the air sent from the blower 102 is installed on the buffer region 35 side with the partition plate 39a interposed therebetween, and is placed on the input region 32 side through the hole of the partition plate 39. It has a structure in which aeration treatment is performed toward the air. By doing so, the large solid matter caught in the hole can be separated from the partition plate 39, and the large solid matter can be diffused into the charging region 32 while preventing the hole from being clogged, and the pulverization process can be performed again. It will be possible.

The pump 33 is driven by the control device 101 of the control unit 100. When the water level of the first adjusting tank 4 in the subsequent stage has a margin, the control device 101 uses the water 31 to be treated in the raw water tank 3 at any time. 1 Pump up to the adjustment tank 4. When the water level of the first adjusting tank 4 is not sufficient, the water to be treated 31 is stored in the delivery area 34 without driving the pump 33, but the float 302 is installed in the delivery area 34 and is set in advance. When the water level exceeds the above water level, the water to be treated 31 is pumped up and sent out regardless of the water level of the first adjusting tank 4.

The water to be treated 31 delivered by the pump 33 from the delivery area 34 of the raw water tank 3 is stored in the first adjusting tank 4. In the first adjusting tank 4, the water to be treated 31 is stored according to the progress of the treatment of the septic tank 5 in the next stage. This is because when the control device 101 determines that the purification treatment of the septic tank 5 is delayed, that is, the water level of the second adjusting tank 6 rises and the amount of water 31 to be treated discharged from the septic tank 5 increases. If it is determined that the water to be treated is slowed down, the water to be treated 31 is stored in the first adjusting tank 4. Further, when it is determined that the purification treatment of the septic tank 5 is proceeding smoothly, that is, when it is determined that the water level of the second adjusting tank 6 is low and the amount of water 31 to be treated discharged from the septic tank 5 is not so large. In order to proceed with the purification treatment of the septic tank 5, the water to be treated 31 is immediately put into the septic tank 5.

Then, aerobic bacteria are present in the first adjusting tank 4, and the aerobic treatment is performed by the aeration treatment through the air diffuser 42 from the blower 102. At the same time, the dissolved oxygen of the water to be treated 31 is increased by the aeration treatment of the air discharged from the air diffuser 42, and the activity of the bacteria in the subsequent treatment is activated. That is, while the water to be treated 31 is stored in the first adjusting tank 4, aerobic treatment can be performed in advance as a pretreatment of the septic tank 5, and the burden of the purification treatment of the septic tank 5 in the subsequent stage can be reduced. Is possible.

In addition, in this first adjustment tank 4, the first fungus bed region 41 which becomes the fungus bed of aerobic bacteria is provided, and the fungus activated in this fungus bed forms a biofilm on the inner wall of the first adjustment tank 4. Then, the aerobic treatment may be performed by the aeration treatment through the air diffuser 42 from the blower 102.

Further, the water to be treated 31 is sent from the first adjusting tank 4 to the septic tank 5 by pumping up by the pump 43, and the drive control of the pump 43 is performed by the control device 101 based on the water level of the second adjusting tank 6. It is done by control.

Further, as shown in FIG. 1, a stirring blade (not shown) and a motor (not shown) for rotationally driving the stirring blade may be arranged on the upper portion of the first adjusting tank 4. There is a possibility that solid matter will be deposited on the upper part of the first adjusting tank 4 (solid matter finely crushed in the raw water tank 3 will float and be deposited), and the aeration treatment through the diffuser pipe 42 from the blower 102 alone will be sufficient. When it is difficult to diffuse the accumulated solid matter, by driving the stirring blade, the accumulated solid matter can be crushed again and sent to the processing tank 5 in the subsequent stage. The drive control of the motor at this time is performed by the control device 101. As for the timing of driving, for example, the motor may be driven periodically, or the motor may be driven periodically, the frictional force is measured, and if the friction is large, it is estimated that solid matter is accumulated. The motor may be driven in earnest.

Furthermore, the pump 43 may be installed at a position where it directly receives the aeration treatment from the blower 102 through the air diffuser 42. By doing so, it becomes possible to prevent the pump 43 from being clogged by the aeration treatment.

Furthermore, a water quality sensor may be installed in the second adjusting tank 6 (not shown), and the control device 101 may control the drive of the pump 43 of the first adjusting unit 4 based on the information of the water quality sensor. That is, when the water quality of the second adjusting tank 6 is good, it is assumed that the purification treatment has been sufficiently performed, and the water to be treated 31 is sent to the septic tank 5, and when the water quality is poor, the purification treatment in the septic tank 5 is performed. However, the water to be treated 31 may be stored in the first adjusting tank 4 as much as possible, and the purification treatment may be slowed down. Further, at this time, although the details will be described later, the return from the second adjusting tank 6 to the raw water tank 3 may be controlled to increase the pace. By doing so, the water to be treated 31 having insufficient purification treatment can be purified again to improve the water quality.

The water to be treated 31 sent out from the first adjusting tank 4 is subjected to full-scale microbial treatment in the septic tank 5. The septic tank 5 has an anaerobic treatment region 51 for performing the first anaerobic treatment, an aerobic treatment region 52 for performing the second aerobic treatment, and a delivery region 53 for sending the water to be treated 31 to the reaction tank 6 in the subsequent stage. Have.

The water to be treated 31 charged from the first adjusting tank 4 is first subjected to the first anaerobic treatment in the anaerobic treatment region 51. In order to perform this first anaerobic treatment over a certain period of time, the anaerobic treatment region 51 is divided into two, and the anaerobic treatment is sequentially performed in each section. Each section is connected by a communicating pipe, and the water to be treated 31 flows between the sections by natural flow. The anaerobic treatment region 51 and the aerobic treatment region 52 communicate with each other so that the treated water 31 can flow above the respective regions, and the treated water 31 subjected to the first anaerobic treatment passes through the communication passage. It is sent to the aerobic processing area 52. In the aerobic treatment region 52, air is sent from the blower 102 to the contact material 56, which is housed in a mesh-like frame 55 and in which aerobic bacteria are resident, through an air diffuser 57, and aerobic treatment is performed. The aerobic treatment region 52 and the delivery region 53 communicate with each other below each region, and the aerobic treated water 31 is delivered to the next second adjusting tank 6. The treatment of the septic tank 5 is performed by natural flow without using a pump or the like. Therefore, the same amount of water to be treated is sent to the second adjusting tank 6 at the same time as the amount of water to be treated 31 is charged.

Further, a part of the water to be treated 31 that has been aerobically treated in the aerobic treatment region 52 is returned to the anaerobic treatment region 51 through a pipe using a pump or an aeration treatment in order to perform sufficient microbial treatment again. It is repeatedly treated so as to obtain a cleaner water to be treated 31. The drive control of the blower 102 and the pump is performed by the control device 101.

The water to be treated 31 treated in the septic tank 5 is stored in the second adjusting tank 6. The second adjusting tank 6 is used to wash the remaining amount of washing water described later and the degree of progress of the treatment of the septic tank 5, that is, the water level of the second adjusting tank 6, the water level of the parking area 73 in the reaction tank 7 described later, and if necessary. The control device 101 determines the progress of the purification treatment based on the water level of the tank 8, and the water to be treated 31 is stored or sent to the reaction tank 7 in the next stage according to the judgment of the control device 101. do. That is, when the water level in the parking area 73 of the washing tank 8 or the reaction tank 7 is low, it is determined that the washing water tends to be insufficient, and the water to be treated 31 is sent to the reaction tank 7. When the water level in the parking area 73 of the washing tank 8 or the reaction tank 7 is rising, it is determined that sufficient washing water is secured, and the water to be treated 31 is stored in the second adjusting tank 6. When the water level of the second adjusting tank 6 also rises, as described above, the progress of the treatment is adjusted by storing the water to be treated 31 in the first adjusting tank 4. The water to be treated 31 is sent from the second adjusting tank 6 to the reaction tank 7 by the pump 62, and the drive control of the pump 62 is performed based on the judgment of the control device 101 as described above.

If the water to be treated 31 is sent to the second adjusting tank 6 in a state where the purification treatment in the septic tank 5 is insufficient, sludge may settle below the second adjusting tank 6. Therefore, the bottom surface portion of the second adjusting tank 6 in which the water to be treated 31 is stored is inclined, and sludge is settled on the tip portion 61 thereof. The height of the inclined tip portion 61 corresponds to the position of the upper surface of the raw water tank 3, and the sludge that has settled is pulled out and returned to the raw water tank 3. Specifically, the tip portion 61 and the upper surface portion of the raw water tank 5 are connected by a pipe, and a solenoid valve is installed in the pipe. This solenoid valve has a structure that is opened periodically or irregularly under the control of the control device 101. When the solenoid valve is opened, sludge accumulated in the tip portion 61 is pulled out and returned to the raw water tank 3. can do. The raw water tank 3 and the second adjusting tank 6 are arranged adjacent to each other or above and below, and by minimizing the length of the pipe, sludge settled in the second adjusting tank 6 can be easily transferred to the raw water tank 3. It is possible to return it and reduce the maintenance work.

The second adjusting tank 6 may also be provided with a fungus bed region 63 similar to that of the first adjusting tank 4, and the activated bacteria may form a biofilm on the inner wall of the second adjusting tank 6. By doing so, the anaerobic treatment can be performed again on the water 31 to be treated stored in the second adjusting tank 6, and the contact material is used while preventing the contact material from being scattered in the tank. It is possible to prevent clogging of piping.

Further, as described above, a water quality sensor may be installed in the second adjusting tank 6 (not shown), and the control device 101 may control the pace of return to the raw water tank 3 based on the information from the water quality sensor. .. That is, when the water quality is poor, the pace of return to the raw water tank 3 (or the amount of return) is increased, and when the water quality is good, the pace of return to the raw water tank 3 (or the amount of return) is decreased. You may let it.

The water to be treated 31 sent out from the second adjusting tank 6 is sprayed from the spraying portion 71 installed above the reaction tank 7 and charged into the reaction tank 7. The reaction tank 7 has a decomposition region 72 (upper region) that decomposes and removes organic substances contained in the water to be treated 31 into carbon dioxide and water, and a parking region 73 (a parking region 73) that stores the water to be treated 31 from which the organic substances have been removed. It has a lower area). The decomposition region 72 is filled with a biochip 74 (for example, cedar chip or the like) implanted with bacteria that decompose organic matter into carbon dioxide and water, and the treated water 31 sprayed from the spraying portion 71 is the water to be treated. Organic matter is removed as it passes through the biochip 74. The water to be treated 31 that has passed through the biochip 74 is stored in the parking area 73 arranged below.

The water to be treated 31 stored in the parking area 73 is purified to a level that can be used as washing water. However, since the water to be treated 31 stored in the parking region 73 passes through the decomposition region 72 while in contact with the biochip 74, it is colored brown. Even if the purification level is sufficient, it is not comfortable for the user when brown water comes out as wash water. In such a case, a color removing filter can be used to remove the brown coloring, and at the same time, a bacteria removing filter can be used to prevent the outflow of bacteria to the next-stage washing tank 8.

The parking area 73 is also provided with a fungus bed area 77 similar to that of the first adjustment tank 4 and the second adjustment tank 6, so that the activated bacteria form a biofilm on the inner wall of the parking area 73. good. By doing so, the anaerobic treatment can be performed again on the water to be treated 31 stored in the parking area 73.

The clean water to be treated 31 (which is the treated water to be reused for cleaning at this point) that has been made transparent by performing the above-mentioned filter treatment is from the parking area 73 under the control of the control device 101. It is sent to the cleaning tank 8 by pumping up. When water is flushed after the toilet 2 is used, the treated water in the washing tank 8 is sent out by the pump 81, the toilet 2 is washed, and the water is circulated in the system again.

The washing water can be circulated by the series of treatments as described above. In the present embodiment, the electric power generated by the solar panel 12 can be used as the electric power for pumping up and driving the control unit 100 required in each process. The electric power generated by the solar panel 12 is stored in the secondary battery 13, and each pump or control unit 100 processes the electric power while consuming the electric power as needed. The solar panel 12 may be installed on the roof, or the sheet type may be attached to the side wall of the bio-toilet system 1.

FIG. 3 is a diagram showing the configuration of the control unit 100 in FIG. 1. As described above, the control unit 100 includes a control device 101 that monitors and controls the entire bio-toilet system 1, an air diffuser 38 arranged in the raw water tank 3, and a diffuser arranged in the first adjustment tank 4. It is provided with at least a blower 102 that sends air to the trachea 42 and the air diffuser 57 arranged in the septic tank 5. In addition, a power conversion device for converting AC / DC, a secondary battery for storing the power generated by the solar panel 12, and the like may be provided.

Each of these devices is housed in one common housing 110. The control device 101, the power conversion device, and the secondary battery generate heat as they are used, and in the worst case, the heat may cause the device to stop. In general, there are many cases where a cooling sheet is used or a fan is attached to cool the device. When a cooling sheet is used, maintenance work such as replacement of the cooling sheet is required, which is not efficient. Therefore, in the present embodiment, the control device 101 is cooled by taking in the outside air into the housing 110 by a fan.

On the other hand, especially in winter, the microorganisms may become inactive and the treatment efficiency may decrease, so it is necessary to raise the temperature to some extent in order to activate the microorganisms. Therefore, using a heater or the like leads to an increase in power consumption. It is possible to raise the temperature without consuming electric power by using a solar water heater as shown in Patent Document 2 described above, but installing a solar water heater makes the system larger and periodically. Maintenance will also occur. Moreover, in the area where the solar water heater is installed, the opportunity to generate energy by solar power generation or the like is deprived.

Therefore, in the present embodiment, by transferring the excess heat generated in the control unit 100 to each tank by the blower 102, it is possible to keep the temperature in each tank as high as possible while lowering the temperature of the control unit 100. And. In FIG. 3, a control device 101 having high heat generation, a power conversion device 103, a secondary battery 104, etc. (hereinafter referred to as a control device 101, etc.) are arranged in the lower stage of the housing 110, and a blower 102 is arranged in the upper stage thereof. Are arranged. Air can flow between the control device 101 and the like and the blower 102, and the air warmed by the control device 101 and the like rises to the blower 102 side.

The blower 102 sucks the air in the housing 110 and sends the air to each air diffuser pipe (air diffuser pipes 38, 42, 57) in a high pressure state. The air sent out by the blower 102 is air warmed by the control device 101 or the like, and when it is sent to each tank through each air diffuser pipe, the heat generated by the control device 101 or the like is also sent through each air diffuser pipe. It will be moved to the tank.

In FIG. 3, the blower 102 is described as one configuration, but as shown in this figure, one blower 102 sends air to each of the air diffuser pipes 38, 42, and 57 by branching the pipe. The blower 102 (for example, the blower 102a that sends air to the air diffuser 38, the blower 102b that sends air to the air diffuser 42, and the air diffuser 57) individually for each of the air diffuser pipes 38, 42, and 57. May be provided with a blower 102c) that delivers air to the air. In this case, since the aerobic treatment is not performed in the raw water tank 3 (because there is no need to activate the microorganisms existing in the raw water tank 3), the blower is provided in the diffuser pipe 38 arranged in the raw water tank 3. It is not necessary to transfer heat from 102a without fail. Therefore, the blower 102a may be disposed at any position in the housing 110 in addition to the upper portion of the control device 101 or the like. Further, both the blower 102b that sends air to the air diffuser pipe 42 arranged in the first adjusting tank 4 and the blower 102c that sends air to the air diffuser pipe 57 arranged in the treatment tank 5 are aerobic treatment. Since it is desirable that heat is transferred evenly in order to activate the microorganisms that carry out the above, the blower 102b and the blower 102c may be arranged side by side in the horizontal direction.

As shown in FIG. 3, the housing 110 is formed with distribution ports 111a and 111b for circulating air from the outside, and is configured to allow outside air to flow at a temperature lower than the temperature inside the housing 110. .. By providing such distribution ports 111a and 111b, it is possible to more effectively cool the control device 101 and the like to protect the device. Further, the blower 102 itself can be cooled by the outside air flowing through the distribution ports 111a and 111b.

At this time, in order for the blower 102 to effectively transfer the generated heat to each tank through each diffuser pipe while cooling the control device 101 and the like as effectively as possible, the distribution ports 111a and 111b are the control device 101 and the like. It is desirable to distribute below. By doing so, the heat generated by the control device 101 or the like is collected in the upper part of the housing 110, and the low-temperature air flowing in from the outside is collected in the lower part of the housing 110, so that the control device 101 or the like is cooled from below. At the same time, the blower 102 can efficiently suck the air in the housing 110 that is warmed by the control device 101 or the like and rises.

In FIG. 3, in order to lower the temperature of the air flowing through the distribution ports 111a and 111b of the housing 110, the water stored in the bio-toilet system 1 may be used to cool the air. FIG. 4 is a diagram showing a configuration of piping when cooling the air circulating in the housing. In the bio-toilet system 1 according to the present embodiment, the washing tank 8 stores water relatively stably. The water stored in the washing tank 8 is already treated water, and since it is reduced by the use of the toilet and constantly increased by the purification treatment, a relatively large amount of water is stably stored. Here, as shown in FIG. 4, in the present embodiment, by using the water stored in the washing tank 8, the air flowing through the distribution ports 111a and 111b of the housing 110 is heat-exchanged and cooled.

In FIG. 4, a pipe 82 for inflowing outside air into the housing 110 is connected to the inflow port 111a of the housing 110 through the cleaning tank 8. A fan 83 is arranged at the inflow port 82a of the pipe 82 so as to take in outside air. The outside air taken into the pipe 82 is heat-exchanged with the treated water stored in the cleaning tank 8 until it flows into the housing 110 through the pipe 82 and is cooled. The cooled air flows into the housing 110 as it is from the distribution port 111a of the housing 110, and efficiently cools the control device 101 and the like.

The pipe 82 is made of a material having high thermal conductivity in order to efficiently exchange heat with the treated water. Further, even when the water level of the treated water drops, it is arranged along at least the bottom surface portion 84 of the washing tank 8 in order to increase the contact area with the treated water as much as possible. At this time, as shown in FIG. 4, the structure of the pipe 82 of the bottom surface portion 84 may be made bellows-like to increase the contact area. In addition, for example, by arranging fins (not shown) on the surface of the pipe 82 or forming the pipe 82 in a spiral shape (not shown) along the bottom surface of the cleaning tank 8, the contact area with the treated water is increased. You may do so.

In this way, the external air is cooled by the treated water stored in the cleaning tank 8 and the cooled air is sent to the housing 110 to suppress the temperature rise of the control device 101 and the like, resulting in equipment failure. Etc. can be minimized.

FIG. 5 is a diagram showing a state in which the air sent from the blower 102 is aerated in the first adjusting tank 4. Here, the bubbles released from the air diffuser 42 are microbubbles. By making the bubbles discharged from the air diffuser 42 into microbubbles, the contact area between the bubbles and the water to be treated 31 becomes large, and the heat of the control device 101 or the like contained in the air sucked by the blower 102 is applied to the water to be treated. It becomes possible to move to 31 efficiently. By doing so, the microorganisms in the first adjusting tank 4 are activated, and the aerobic treatment can be efficiently performed.

As with the first adjusting tank 4, it is desirable that the air diffuser pipe 57 arranged in the treatment tank 5 also releases microbubbles into the water to be treated 31.

As described above, in the bio-toilet system according to the present embodiment, the blower 102 and the control device 101 and the like are arranged in a common space, and the blower 102 sucks the air warmed by the control device 101 and the like. Then, since the air is discharged from the air diffuser pipes 42 and 57 arranged in the first adjusting tank 4 and the processing tank 5, the heat generated by the control device 101 and the like passes through the blower 102 to the first adjusting tank 4 and the processing tank 5. It is possible to activate the microorganisms in the first adjusting tank 4 and the processing tank 5 while cooling the control device 101 and the like (discharging the heat of the control device 101 and the like), and the bio-toilet system 1 is energy-saving and efficient. Can be driven.

Further, since the blower 102 and the control device 101 and the like are arranged in the same housing 110 and outside air flows in from the distribution port 111a provided in the housing 110, the blower 102 and the control device 101 and the like are generated in the control device 101 and the like. The heat is trapped in the housing 110, and the heat can be efficiently transferred to the processing tank 5, the first adjusting tank 4, or the like. Further, since the outside air flows into the housing 110 from the distribution port 111a, the outside air efficiently cools the control device 101 and the like, and at the same time, a large heat drop is generated in the housing 110 to effectively use the energy. can do.

Furthermore, since the outside air flowing in from the inflow port 111a provided in the housing 110 is cooled by heat exchange in the washing tank 8, the flowing outside air is cooled to a lower temperature by the treated water, and this cooling is performed. The control device 101 and the like can be efficiently cooled by the generated outside air, and a larger heat drop can be generated in the housing 110 to effectively use the energy.

Furthermore, since the pipe 82 through which the outside air flows is arranged at least along the bottom surface portion 84 of the washing tank 8, the decrease in heat exchange efficiency is minimized even when the amount of water in the washing tank 8 is reduced. The outside air can be efficiently cooled by exchanging heat with the water in the washing tank 8 through the pipe 82 over a long distance.

Furthermore, since the blower 102 is arranged in the upper stage of the control device 101 or the like in the housing 110, the air warmed by the heat generated by the control device 101 or the like moves upward in the housing 110 and moves thereof. The blower 102 efficiently sucks the generated air and transfers the heat to the processing tank 5 and the first adjusting tank 4.

Furthermore, in order to make the air discharged from the air diffuser pipes 42 and 57 of the blower 102 into microbubbles, the air is sent out as fine bubbles in the treatment tank 5 and the first adjustment tank 4, and the treatment tank 5 and the first adjustment tank 4 are used. The contact area between the water to be treated and the air to be sent out becomes large, and heat can be transferred efficiently.

(Second Embodiment of the present invention)
The bio-toilet system according to this embodiment will be described with reference to FIG. The bio-toilet system according to the present embodiment is an application of the bio-toilet system according to the first embodiment, and the air flowing into the housing 110 in which the blower 102, the control device 101, and the like are housed is taken from the outside air. It switches according to the temperature.

FIG. 6 is a diagram showing a configuration of an air pipe to be circulated in a housing in the bio-toilet system according to the present embodiment. In FIG. 6, there are two air flow paths flowing into the housing 110. One is the first route in which the outside air flows in from the inflow port 111a while exchanging heat through the washing tank 8, and the other is the second route in which the outside air is taken in from the toilet room and flows in, as in the case shown in FIG. Is. A solenoid valve 112 is arranged at the branch point of each route, and the opening / closing of the valve is controlled by the control device 101.

Specifically, the control device 101 receives temperature information from a thermometer (not shown) installed outside the bio-toilet system 1, and if the outside air temperature is below freezing, the outside air is taken in from the first route. When the control device 101 controls the electromagnetic valve 112 and the temperature of the outside air is below the freezing point, the control device 101 takes in the air by the second route from the toilet room where the temperature is higher than the outside air temperature. Controls the electromagnetic valve 112. This is to prevent a part of the control device 101 from being damaged by freezing when the control device 101 or the like is cooled by the air below the freezing point because the temperature of the air is too low.

In FIG. 6, the branch point of the pipe 82 is provided at the rear stage of the cleaning tank 8 and immediately before the inflow port 111a of the housing 110, but the branching point may be provided at the front stage portion of the cleaning tank 8.

As described above, in the bio-toilet system according to the present embodiment, by switching the air flowing into the housing 110 according to the outside air temperature, damage to the control device 101 and the like is surely prevented, and the labor of maintenance work is reduced. can do.
