Description

  The present invention relates to a biotoilet device for decomposing excrement by heat and microorganisms and an operation method thereof.

  In general, in a so-called biotoilet device that decomposes excrement by microorganisms (bio fungi) and heat, the bio fungus in the treatment tank is propagated and the excrement is eliminated. For this reason, it is not necessary to pump out excrement, and furthermore, since it is not necessary to drain it into sewage, it is known as an environmentally friendly toilet.

  In such a biotoilet device, heating control (temperature control) in the processing tank is performed by heating means such as an electric heater in order to activate biobacteria (maintenance of the breeding environment) and adjust moisture in the processing tank. ing. That is, the heating means is on / off controlled to maintain the inside of the processing tank at a predetermined temperature (for example, about 30 ° C.) (for example, see Patent Document 1).

On the other hand, in order to activate biobacteria, it is also necessary to maintain the inside of the treatment tank at an appropriate water content (for example, about 70% moisture content). Therefore, when the water content decreases, the treatment tank Water will be supplied. Furthermore, although the biobacteria are put in the treatment tank as a biochip, the biochip is reduced by about 10% to 15% per year. And if a biochip reduces, processing capacity will fall, Therefore It is necessary to replenish a biochip in a processing tank suitably.

  With reference to FIG. 3, the control apparatus 30 of the biotoilet apparatus 10 is demonstrated. Control of the temperature and humidity inside the processing tank 13, water supply, and biochip replenishment control are performed by a control device 30 having a microcomputer. The control device 30 is connected to the temperature sensor 31, the weight detection sensor 32, the lower limit level meter 33, and the humidity sensor 34. The control device 30 has a detected temperature, a detected weight, a lower limit level, and a detected humidity. Is given.

  In addition, a switch device 35 is connected to the control device 30, and the switch device 35 is turned on / off to control energization to the electric heater 16. Further, an on / off valve 36 such as an electromagnetic valve is connected to the control device 30, and the on / off valve 36 is controlled to open and close to supply water from the water supply tank 21 to the treatment tank 13. The biochip replenisher connected to the biochip tank described above replenishes the biochip to the treatment tank 13 under the control of the control device 30.

  Subsequently, temperature and humidity management, water supply, and biochip replenishment control by the control device 30 will be described with reference to FIG. As described above, the detection temperature (T1), the detection weight (W1), the lower limit level (biochip level: L1), and the detection humidity (H1) are given to the control device 30. The control device 30 is preset with a set humidity (H) and a set temperature (T).

  The appropriate level of the biochip stored in the treatment tank 13 is a level corresponding to a biochip having a volume exceeding at least the above lower limit level. The control device 30 is set with a processing tank weight (W) when an appropriate level of biochip is stored in the processing tank 13.

  The control device 30 calculates the amount of water in the biochip based on the detected weight (W1) and the treatment tank weight (W) given from the weight detection sensor 32 (step S1). That is, since most of the excreta is urine, the weight increase indicated by the detected weight (W1) −the treatment tank weight (W) can be regarded as due to moisture.

  By the way, the detected humidity detected by the humidity sensor 34 increases as the amount of water in the treatment tank 13 increases. And the control apparatus 30 determines whether the water | moisture content in the processing tank 13 is excessive according to detected humidity (H1) and a moisture content (step S2). For example, the lower limit value and the upper limit value of the moisture amount are set in advance in the control device 30, and the detected humidity (H1) is set to the set humidity (H1) in a state where the obtained moisture amount exceeds the upper limit value as described above. H) If it is not less than that, it is determined that there is excessive water.

  When the amount of moisture is excessive, the control device 30 turns on the switch device 35 and energizes the electric heater 16 to evaporate the moisture contained in the stored item (step S3). In addition, since the biochip can withstand temperatures up to about 70 ° C., the influence on the biochip is small.

  Subsequently, the control device 30 determines whether or not there is little moisture in the processing tank 13 according to the detected humidity (H1) and the amount of moisture (step S4). For example, the control device 30 has a small amount of moisture contained in the stored item when the obtained moisture amount is lower than the lower limit value and the detected humidity (H1) is less than the set humidity (H). Is determined. And if it determines with there being little moisture, the control apparatus 30 will open the on-off valve 36, and will supply the process tank 13 with water (step S5).

  Further, the control device 30 performs on / off control of the switch device 35 according to the detected temperature from the temperature sensor 31 to control the energization to the electric heater 16. At this time, energization control according to the detected temperature is not performed. That is, when the moisture adjustment control (moisture adjustment step) is not performed (step S6), the control device 30 performs the energization control to the electric heater 16 according to the detected temperature (step S7).

  Further, the control device 30 controls the biochip replenisher to replenish the biochip stored in the biochip tank 37 to the processing tank 13. This replenishment is a level detected by the lower limit level meter 33. Is done according to. When the level of the biochip falls below the lower limit level, the laser light 33c is received by the light receiving unit 33b from the light emitting unit 33a. When the laser beam is received by the light receiving unit 33b, that is, when the level of the biochip becomes less than the lower limit value (step S8), the control device 30 controls the biochip replenisher to replenish the processing tank 13 with the biochip. (Step S9).

  Then, the control device 30 replenishes the biochip from the biochip tank 37 to the treatment tank 13 by the biochip replenisher until the laser beam 33c from the light emitting unit 33a is not received by the light receiving unit 33b. Then, when the biochip replenishment is completed, the control device 30 returns to step S1.

  In this way, since the internal environment of the processing tank 13 is controlled according to the detected temperature, the detected humidity, and the amount of water contained in the contents stored in the processing tank 13, the biotoilet device is manually operated. There is an effect that maintenance and management are reduced and maintenance is not time-consuming, and further, the breeding environment of the biobacteria can be appropriately maintained.
