In the present invention, as an example, it is assumed that the stirring blade is operated through one stirring driving unit per stirring blade. In the present invention, there are two stirring blades (113, 114), and the stirring driving unit (111, 112) is also implemented as two, but the configuration and operation of the two stirring blades, the configuration or operation of the two stirring driving units are the same, so that the following , For convenience of explanation, only one stirring drive unit (eg, 111) and one stirring blade (eg, 113) will be described.

The stirring blade 113 is connected to the shaft of the motor 111a and has a rotating shaft rotatably across the inside of the fermentation tank 118, and a plurality of blades 121 are provided eccentrically around the rotating shaft at the outer periphery. do.

Here, the plurality of wings 121 are arranged in a pair so as to face each other, and the wings arranged in a pair have different lengths, and at one end of the longer wing, a foreign substance for collecting foreign substances into the center of the fermentation tank The focusing surface 122 is provided. Here, one end means an end side facing the center of the fermentation tank 118 out of the length of the entire wing, and the foreign material collecting surface 122 is formed to be inclined, so that the foreign material is collected at the center of the fermentation tank during stirring.

In addition, the inside of the enclosure 101 controls temperature compensation for fermentation according to the amount of humidity inside the manure fermentor 110, and variably controls the operating time of the manure fermentor 110 according to the amount of humidity. The controller 107 is installed.

As shown in FIG. 3, the controller 107 compares the amount of humidity obtained through the humidity sensor 115 installed in the manure fermentor 110 with a preset reference humidity amount, and according to the difference, the manure fermentor ( A control unit 140 having a temperature compensation unit 142 for controlling the driving of the heater 116 provided at 110 to compensate for fermentation temperature, and provided in the manure fermentor 110 under the control of the control unit 140 It includes a heater driving unit 180 for driving the heater (116).

In addition, the controller 107 includes a lighting driving unit 160 that turns on or off the lighting of the lighting unit 104, and the control unit 140 detects a human body in the toilet space by the human body detection sensor 105 And a lighting control unit 141 that controls the lighting driving unit 160 to maintain the lighting state of the lighting unit 104.

In addition, the control unit 140 may include a stirring control unit 143 for preventing power waste by varying the rest time of the stirring driving unit 111 according to humidity.

The operation of the eco-friendly mobile bio toilet according to the present invention configured as described above will be described in detail as follows.

When the user opens the door to use the bio toilet and starts entering the toilet space, the human body detection sensor 105 provided in the lighting unit 104 detects the human body. Here, the human body detection sensor 105 may use an infrared human body detection sensor, a heat detection sensor, a Doppler type moving object detection sensor, and the like, which are already known.

When a human body is detected by the human body detection sensor 105, the control unit 140 of the controller 107 drives the lighting driving unit 160 through the lighting control unit 141 to turn on the lighting unit 104. Here, if the motion sensor is used as the human body detection sensor, if there is no movement while the user is viewing the toilet in the toilet space, it is determined that the human body is not detected and the lighting is automatically turned off. This may cause the user to be surprised or experience many other inconveniences as the actual user is in a state of toileting or is turned off. In order to improve such discomfort, the present invention uses a heat detection method, and in a situation in which the human body is detected, the lighting unit 104 is continuously lit by the lighting control unit 141 through the lighting driving unit 160 regardless of the presence or absence of movement of the human body. Keeps it in a state.

Next, when a user is detected, the control unit 140 of the controller 107 extracts the voice data for prohibition of input of foreign substances stored in the voice storage unit 150 and transmits the extracted voice data to the voice output unit 170. The audio output unit 170 converts the transmitted audio data into an audio signal and transmits it through the speaker 103. As a result, the user for toileting recognizes the voice for prohibiting the introduction of foreign substances through the speaker 103, and suppresses the input of foreign substances that are not fermented by the fermentation accelerator.

On the other hand, when the user finishes toileting, operates the drainage lever, and exits the bio toilet, the human body is not detected and the controller 107 automatically turns off the lighting unit 104 through the lighting driving unit 160.

In addition, the manure drained through the left toilet 106 is introduced into the fermentation tank 118 of the manure fermentor 110.

The manure fermenter 110 rotates the first motor 111a of the stirring driving unit 111 under the control of the stirring control unit 143 of the controller 107 and is connected to the axis of the first motor 111a. The shaft rotates corresponding to the rotation of the first motor 111a, thereby rotating the stirring blade 113 connected to the rotation shaft.

When the stirring blade 113 rotates, the fermentation accelerator and the manure are stirred. At this time, the stirring blade 113 consists of a pair of two blades of different lengths, so that the mutual installation position around the rotation axis has an eccentricity. It is installed and rotates while being eccentric. When the stirring operation is performed while being eccentric in this way, the fermentation accelerator and the manure are mixed better, thereby increasing the fermentation efficiency.

Here, the fermentation accelerator may include sawdust, wood chips such as cedar, and microorganisms. The blending ratio of lactic acid bacteria, yeast bacteria and Bacillus bacteria among the microorganisms used in the microbial production of biochips is based on 100 weight of lactic acid bacteria: yeast bacteria: bacillus bacteria = 10 kg: 2 kg: 100 g. Bentonite 0.25 ~ 0.5kg is mixed with 200 liters of the culture solution, and the mixture is at a temperature of 35℃, and the amount of oxygen supplied

Cultured under conditions of 200 to 400 L/min can be used.

If a lot of the above bacteria are added to either side, there is a risk of decay during microbial cultivation, so it is preferable to add purified glucose and molasses to 200 liters of the culture medium at an additional 10 kg:10 kg.

The fermentation accelerator completely decomposes and destroys manure and tissue paper.

At this time, the heater 116 is driven by the heater driving unit 180 so that the fermentation accelerator and the manure are heated to 30°C or higher when agitated by the stirring blade 113, so that microorganisms are not destroyed by low temperature. It is cultured so that the process of extinction of biological fermentation by microbial culture can be optimized.

That is, the temperature compensation unit 142 of the controller 107 compares the amount of humidity detected by the humidity sensor 115 with a preset reference humidity amount, and when the humidity amount is greater than the reference humidity amount, the heater 116 The fermentation temperature is compensated by driving to prevent insufficient fermentation depending on the amount of humidity. When the detected humidity amount is included in the reference humidity amount, driving of the heater 116 is stopped.

On the other hand, as another feature of the present invention, when the fermentation accelerator and manure are stirred by the stirring blade 113, foreign substances 117 such as wet tissues or women's sanitary napkins (mainly put in the toilet) are added to the fermentation tank 118. It is concentrated in the center of the fermentation tank 118 so that the operator can easily remove it. That is, the plurality of blades 121 of the stirring blades 113 are arranged in a pair to face each other, and the blades arranged in a pair have different lengths, where at one end of the longer blade, foreign substances are removed during stirring. By forming a foreign substance collecting surface 122 including an inclined surface for focusing to the center of the fermentation tank 118, when agitated, the foreign substance 117 is transported to the top by riding the longer wing, and then the wing descends again. When doing so, ride the inclined surface of the foreign matter connection surface 122 to be focused to the center of the fermentation tank 118. When the foreign matter 117 is concentrated in the center of the fermentation tank 118 in this way, the operator can easily remove the foreign matter 117 in the future. In particular, when the foreign material 117 is focused to the center of the fermentation tank 118, the foreign material 117 is prevented from being wound on the rotating shaft coupled to the stirring blade, and thus the motor generated when rotation is not performed by the foreign material 117 There is an advantage that can prevent damage or failure of the manure fermenter.

In addition, odors or other odors generated during fermentation in the toilet space are discharged to the outside through the ventilator 102, so that the air inside the bio toilet can be kept in a clean state at all times.

In addition, as another feature of the present invention, the humidity sensor 115 installed in the fermentation tank 118 is used to detect the humidity in the fermentation tank 118, and the controller 107 controls the control unit 140 according to the detected amount of humidity. By controlling the driving of the stirring driving unit 111 through the stirring control unit 143 of, it is possible to achieve power saving by optimally controlling the rest time. That is, the stirring control unit 143 compares the humidity detected by the humidity sensor 115 with the idle reference humidity set in advance for control of the idle time, and if the detected humidity is lower than the idle reference humidity, the pause time is shortened. On the contrary, if the detected humidity is higher than the reference humidity for rest, the rest time is set longer. Through this variable control of the rest time, the stirring operation can be optimally controlled, as well as the waste of power generated by unnecessarily driving the stirrer can be prevented.

Although the invention made by the present inventor has been described in detail according to the above embodiment, the present invention is not limited to the above embodiment, and it is common knowledge in the art that various changes can be made without departing from the gist of the invention. It will be self-evident to those who have.
