Description
MOVABLE TEMPORARY TOILET
Technical Field
[1] The present invention relates generally to a movable toilet to automatically transform human excrement into organic compost. More particularly, the present invention relates to a movable temporary toilet transforming the excrement into the organic compost by using a transport means, a microorganism feeding means, a stirring means and a purifying means and enabling washing of the toilet by using water generated from urine.
Background Art [2] After a toilet is used, human excrement is generally flushed by using water and sent to a purification tank, stored therein for a predetermined period and delivered to sewage treatment facilities to be treated in various ways. [3] A restroom should be generally equipped with at least one water tank, a toilet paper and a purification tank. [4] In most restrooms, human excrement is flushed by water and nationwide water consumption in Korea is estimated to increase by several tens of thousand tons every year. Korea is likely to run short of water resources in the near future. Therefore effective countermeasures should be devised urgently. [5] Artificial fertilizers are used more often than organic composts for planting crops because they are easily available and convenient. As a result, soil is acidified very rapidly. However any special countermeasure to prevent soil acidification is not provided yet. [6] Human excrement discarded from vessels is regarded as one of main causes of ocean contamination. Therefore improper discarding of human excrement is prohibited by the law. [7] In the case of movable temporary toilets installed in the outside now, most users hesitate to use due to bad odors of the excrement.

[77] A plurality of partitions 820 are installed maintaining a predetermined distance from the urine collector 800 to shield the user when it uses the urine collector 800.
[78] The stair 110 is formed as a single body on a side of the main body 100 for the user to enter into the main body 100 after ascending the stair 110.
[79] A door 140 is installed on the top of the stair 110. A foothold 130 is installed near the door 140 and has the same height as the top of the stair 110 for the user to put its feet thereon and use a toilet comfortably. The toilet 150 with a predetermined height is installed near the foothold 130 formed with the predetermined height on the main body 100. A seat 151 is installed on the toilet 150 for the user to sit down. A cover 152 which may be open or close is installed on the surface of the seat 151 and is connected to the seat 151 by a hinge 153.
[80] A paper cover 154 for covering the seat 151 is provided at a side of the toilet 150 for the user to use the paper cover when it sits on the seat 151 and relieves itself.
[81] A paper discharge hole 170 is installed on a side wall of the main body 100 to discharge a used paper to outside of the main body. The used paper is discharged through the paper discharge hole 170, and the discharged paper is collected in a separate envelope (not shown) for collection and may be disposed later.
[82] A switch 910 is installed under the seat 151, and is pressed when the user sits on the seat 151.
[83] A transport means 200 is installed under the toilet 150 to convey excrement when the switch 910 is pressed by the seat 151.
[84] A conveyor 210 is installed in the transport means 200 to convey the excrement to a stirring means 400 by an operation signal of the switch 910 pressed by the seat 151.
[85] Rollers 211 are installed in two ends of the conveyor 210 and rotate smoothly to
convey the excrement. A motor (not shown) is installed in a controller 900 at a side of the roller 211, and the controller 900 is installed at a predetermined location outside the main body 100. [86] A first water supply pipe 531 is installed above the conveyer 210 to supply water and wash the conveyer 210, and thereby the residual excrement on the conveyer is removed completely and odors are prevented at the same time [87] At least two nozzles 532 and 533 are installed at an end of the first water supply pipe 531 to spray water towards the surface of the conveyer 210. [88] An excrement removal fan 220 driven by the motor is installed at a side of the conveyer 210 to remove the excrement transported from the conveyer 210. [89] Residual excrement on the surface of the conveyer 210 is removed almost completely by an excrement removal piece 221 installed under the conveyer 210. [90] A main water supply pipe 530 is installed between a pump 524 and the first water supply pipe 531 to supply water in a tank 523 to the first nozzle 532 and the second nozzle 533. [91] A guide member 230 is installed under the excrement removal fan 220 to receive the fallen excrement from the conveyer 210 and guide to the excrement removal fan
220. [92] A microorganism feeding means 300 is installed at the rear side of the seat 151 of the toilet 150 to supply microorganisms for producing organic compost. [93] The microorganism feeding means 300 has a feeder 310 installed on the main body
100 to feed microorganisms through a feeding pipe 311. A predetermined space is formed to store microorganisms fed through the feeder 310. [94] A hopper 320 having a feeding hole 321 is installed to supply a predetermined amount of microorganisms to the stirring means 400. [95] A feeding fan 330 driven by the motor is installed in the feeding hole 321 to supply a predetermined amount of the microorganisms while the transport means 200 works. [96] A stirring means 400 is installed under the microorganism feeding means 300.
[97] The stirring means 400 has a stirring fan 410 near an end of the guide member 230, working with the excrement removal fan 220 of the transport means 200, to stir the excrement transported from the excrement removal fan and microorganisms supplied by the feeding fan 330.
[98] A reservoir 430 is formed under the stirring fan 410. The reservoir 430 stores a pre¬ determined amount of the excrement and microorganisms while the excrement and mi¬ croorganisms are stirred. [99] After the excrement is dried, a discharge fan 420 breaks the excrement into pieces and discharges them. A discharge pipe 440 protruding from a side of the main body
100 is installed under the discharge fan 420 to collect the broken excrement discharged
through the discharge fan 420 in a bag or a reserve tank.
[100] An excrement heater 500 is installed inside the main body 100 to dry the excrement conveyed by the conveyer 210 of the transport means 200.
[101] A room 160 is formed under the foothold 130 to collect urine coming from the urine collector 800 and urine from the toilet coming along a guide panel.
[102] A urine heater 510 is installed on the bottom surface of the room 160 to evaporate urine when urine is collected through the urine supply means 810 of the urine collector 800 and through the purifying means of the room 160. The urine purified by the filter 813 is supplied to the room 160 and is evaporated.
[103] The urine heater 510 supplies heat to the purified urine supplied from the urine collector 800 and the urine supplied through the purifying means 1000 which will be explained later in detail.
[104] The condensing means 520 is installed in the upper part of the room 160 to condense moisture generated by heating the urine.
[105] The condensing means 520 has a condenser 522 to cool down the moisture generated by the urine heater 510. A fan 525 is installed in the rear surface of the condenser 522 to discharge gases contained in the air by sucking the air including moisture.
[106] A tank 523 is installed under the condenser 522 to collect water generated from the condenser 522 after transforming moisture into water by cooling down the air including moisture sucked by the fan 525 in the condenser 522.
[107] A pump 524 is installed inside the tank 523 to supply the collected water to nozzles with a predetermined pressure.
[108] The water supplied by the pump 524 is supplied to a first nozzle 532 and a second nozzle 533 with a predetermined pressure, and the conveyer 210 and the excrement removal fan 220 are cleaned by water sprayed through the first nozzle 532 and the second nozzle 533.
[109] The purifying means 1000 comprises a first purifier 1100 installed under the stair
110 to collect urine coming from the toilet and purify the urine; a second purifier 1200 to further purify the urine coming from the first purifier 1100; a third purifier 1300 to further purify the urine coming from the second purifier 1200; a fourth purifier 1400 to further purify the urine coming from the third purifier 1300; and partition panels 1600 installed in the room 160 having a predetermined distance therebetween to prevent the purified urine from being mixed together when the urine is purified in the first, second, third and fourth purifiers 1100,1200,1300 and 1400. Discharge holes 1500 are formed on the partition panels.
[110] The discharge holes 1500 are formed on one partition panel 1600 dividing the first purifier 1100 and the second purifier 1200 and on another partition panel 1600
dividing the third purifier 1300 and the fourth purifier 1400.
[Ill] The first purifier 1100 is made of absorbent materials with predetermined large particles like gravels, briquettes and so on. The second purifier 1200 is made of smaller particles like sands than the materials used in the first purifier 1100.
[112] The third purifier 1300 is made of textile materials such as nonwoven fabrics to further absorb impurities that are not removed in the first and second purifiers. The fourth purifier 1400 is made of charcoals to further purify the urine coming from the third purifier 1300.
[113] The urine purified by gravels, briquettes, sands, nonwoven fabrics and charcoals in the first, second, third and fourth purifiers (1100,1200,1300 and 1400) is transported through the discharge holes 1500. The purified urine moves from the first purifier 1100 to the second purifier 1200 and from the third purifier 1300 to the fourth purifier 1400 through the discharge holes 1600 formed on lower parts of the partition panels 1600. The purified urine is transported through the discharge holes 1500 on the upper part of the partition panel 1600 when it moves from the second purifier 1200 to the third purifier 1300 and from the fourth purifier 1400 and to the room 160.
[114] Operation procedures and effects of a movable temporary toilet according to an embodiment of the present invention will be described hereinafter.
[115] In a state that a user enters into a main body 100 through a stair 110 to relieve itself, the user puts a paper cover 154 disposed at a side of a toilet 150 on the seatl51. In the case that a cover 152 of the toilet 150 is close, the user opens the cover 152 and puts the paper cover 154 on the seat 151 and relieves itself.
[116] When the user rotates the cover 152 in one direction to use the toilet, the cover 152 rotates around the axis of a hinge 153 and the seat 151 is shown.
[117] A switch 910 disposed under the seat 151 is pressed when the user sits on the seat
151 to relieve itself.
[118] An operation signal of the switch 910 generated by pressing the seat 151 is sent to a controller 900 and electric power is supplied to drive the conveyer 210 of the transport means 200.
[119] The electric power is supplied to a motor to drive a excrement removal fan 220 installed at an end of a conveyer 210, the feeding fan 330 of microorganism feeding means 300, the stirring fan 410 and the discharge fan 420 of a stirring means 400.
[120] The motor installed inside the controller 900 drives the feeding fan 330, the stirring fan 410 and the discharge fan 420 of the stirring means 400, working together with the conveyer 210. The motor is driven by the signal of the controller 900.
[121] The electric power is supplied to the conveyer 210, the feeding fan 330, the stirring fan 410 and the discharge fan 420 of a stirring means 400 only when the toilet is being used.
[122] The electric power is supplied to an ozone generator 600, an excrement heater 500 and a urine heater 510 for a preset time or continuously to evaporate moisture contained in the excrement and dry completely. [123] When a user relieves itself, the excrement and the urine are separately treated. The urine is sent into a purifying means 1000 along a guide panel 521 and the excrement are transported by the conveyer 210 installed under the seat 151. [124] The urine is supplied to a first purifier 1100 of the purifying means 1000 installed under the guide panel 521 inside the main body 100 to purify the supplied urine by using materials of large particles such as coal ashes. [125] The urine purified in the first purifier 1100 is supplied from the lower part of the first purifier 1100 to a second purifier 1200. [126] The urine supplied to the second purifier 1200 is further purified by using materials such as sands including smaller particles than the coal ashes of the first purifier 1100, and the purified urine is sent to a third purifier 1300 through the upper part of a partition panel 1600. [127] The urine supplied to the third purifier 1300 is further purified by using textile materials such as nonwoven fabrics, and the purified urine is transported to the fourth purifier 1400 through the lower part of the partition panel 1600. [128] The urine supplied to the fourth purifier 1400 is further purified by charcoal, and the purified urine is transported into a urine heater 510 through a discharge hole 1500. [129] In the case of the excrement treatment, when a user sits on a seat 151, a switch 910 is pressed, and an operation signal is sent to a controller 900 to drive a conveyer. [130] The excrement placed on the surface of the conveyer 210 is conveyed to the excrement removal fan 220 by the rotation of the conveyer 210. [131] The excrement transported by the conveyor 210 are removed almost completely from the conveyor 210 by the excrement removal fan 220, guided by the guide member 230, and subsequently sent to the stirring means 400 by the excrement removal fan 220. [132] Even in the case that the excrement is not completely removed by the excrement removal fan 220, the excrement are again removed by an excrement removal piece 221 installed under the conveyer 210. [133] The excrement transported to a stirring means 400 is mixed with microorganisms while moisture of the excrement is evaporated. [134] The excrement transported by the conveyer 210 is sent at a proper speed to dry moisture contained in the excrement completely by heating. [135] The excrement conveyed by the transport means 200 are dried by an excrement heater 500 installed in the main body 100 so that the excrement without moisture is removed easily by the excrement removal fan 220.
[136] The excrement stirred with microorganisms by the stirring fan 410 is broken by the rotation of the discharge fan 420, and the broken excrement is discharged through a discharge pipe 440 protruding to the outside of the main body 100. [137] The broken excrement discharged through the discharge pipe 440 does not have odors of the excrement itself since it is mixed with microorganisms. [138] Ammonia gas is not left in the main body 100 because gases and odors are discharged through an exhaust pipe 700 in the main body 100. [139] Gases and odors are sterilized and deodorized by ozone just before they are discharged through the exhaust pipe . [140] Microorganisms are not sterilized by ozone since the ozone generator sterilizes only the lower part of the exhaust pipe. The microorganisms are not influenced by the ozone because microorganisms stored at the hopper fall downwards and are mixed with the excrement. [141] In a state that the transportation of the excrement are finished, if the controller 900 sends a signal to a pump 524 to remove the excrement left on the conveyer 210 completely, water stored at a tank 523 is supplied to a first nozzle 532 and a second nozzle 533 through a main water supply pipe 530. [142] Water is sprayed to the conveyer 210 by the first nozzle 532 and the second nozzle
533 to eliminate the residual excrement on surface of the conveyor 210 and thereby a next user may use the toilet in a sanitized state. [143] The urine collected at a urine collector 800 is transported to a filter section 811 through a first urine supply pipe 801 installed at the bottom of the urine collector 800, and components such as urea contained in the urine are removed by a filter 813 disposed inside a case 812. [144] The urine from which components such as urea have been removed is supplied to the room 160 through a second urine supply pipe 802, and the urine is evaporated by a urine heater 510. [145] The evaporated moisture is condensed on the lower surface of the foothold 130, and the condensed moisture is transformed into water and moved to the tank 523 along the guide panel 521. [146] Moisture contained in air of the room 160 is transformed into water by the condenser 522, and the collected water is transported to the tank 523. [147] The conveyer 210 is washed by water stored in the tank 523 through the first nozzle
532 and the second nozzle 533 in a state that a predetermined period has passed after use. [148] "Predetermined period has passed"means a state that the conveyer 210 is washed by spraying water through the first nozzle 532 and the second nozzle 533 in a state that excrement has been removed from the conveyer 210 by the excrement removal fan 220
and it has been completely transported to the stirring means 400. [149] The water sprayed through the first nozzle 532 and the second nozzle 533 is supplied from the upper side of the conveyer 210 to prevent the urine of the user from splashing up to the first nozzle 532 and the second nozzle 533. [150] Water condensed in the condenser 522 and collected by the guide panel 525 is supplied to the first nozzle 532 and the second nozzle 533 through the main water supply pipe 530 by the operation of a pump 524, and it is sprayed for washing. [151] As described above, a movable temporary toilet according to the present invention has an advantage that clean toilets are always maintained because the conveyer 210 and the excrement removal fan 220 are washed by water generated from urine in a state that the excrement are completely treated without using water. [152] As an additional advantage, soil acidification is prevented and growth of crops is promoted because the excrement is stirred with microorganisms and may be utilized as organic composts. [153] As a further advantage, it is convenient for a man to urinate because the urine collector 800 is separately installed in the outside of the main body 100 and he does not need to go inside the main body 100 for urination.
Industrial Applicability [154] A movable temporary toilet according to the present invention may provide organic composts by drying excrement utilizing heat and mixing with microorganisms. It may prevent odors generated by the excrement in the toilet, and wash the toilet by water generated from urine when it is installed at a park, a construction site or a parking lot.
