Simple toilet equipment

"Technical field"

The present invention can be temporarily installed in various facilities, such as construction sites, factories, pleasure boats, parks, sightseeing spots, etc., in which the usage rate of toilets fluctuates greatly over time, and can be used by elderly people in homes and medical facilities. The present invention relates to a simplified toilet device having a filth disposal function suitable for use in nursing care for patients who have difficulty walking.

"Background technology"

Conventionally, a simplified toilet device that stores waste in a storage container, collects the waste and the storage container when the storage reaches a predetermined amount, transports the waste to a disposal site, and processes the waste is used. . This type of simplified toilet has the problem that odor is always generated due to the storage of waste and the inconvenience of using the collected waste and storage containers that must be transported to the disposal site. Was. Therefore, a chip carrying microorganisms that have the function of decomposing and extinguishing filth is stored in the storage container, and the microorganisms in the chip decompose the filth to eliminate the generation of odors. A simple toilet device having a function of extinguishing has been proposed.

However, in the proposed simple toilet device utilizing the action of microorganisms, it is necessary to heat the chips in order to efficiently treat waste. Therefore, a hot toilet generating facility is attached to the simple toilet device, and dirt and chips are stirred by the stirring blades provided in the storage container while blowing hot air into the storage container.

For this reason, the following problems occur with this type of simple tray device. I was (1) Since the waste and the chips are stirred using the stirring blades, the chips are gradually pulverized, the carrying capacity of microorganisms is reduced, and the efficiency of decomposing and eliminating the waste is reduced.

(2) Blowing in hot air is inefficient in heating chips, and requires long-time blowing of hot air, which increases the heat energy cost of a simple toilet device.

(3) Frequent humidity control must be performed to prevent drying inside the storage container due to blowing in hot air and maintain the storage container in the optimal humidity condition for microbial activity.

(4) When installing a simplified toilet device, it is necessary to supply power for auxiliary equipment such as hot air generators, which increases the installation cost of the simplified toilet device.

The present invention has been made in view of the above circumstances, and it is expected that the function of decomposing and extinguishing filth will be maintained for a long period of time, that no human humidity control will be required, and that installation and maintenance costs will be low and economical. An object of the present invention is to provide a simplified toilet device utilizing the action of different microorganisms.

"Disclosure of the invention"

A simplified toilet apparatus according to the present invention, which meets the above-mentioned object, comprises: a sewage treatment tank in which chips carrying microorganisms that decompose and eliminate sewage are stored; a toilet bowl above the sewage treatment tank; and a sewage treatment tank. A support frame for supporting the toilet bowl at a predetermined position with respect to the waste disposal tank, a stirring blade provided in the waste disposal tank for stirring the waste and chips, and a rotating drive for rotating the stirring blade. Means, and a controller for controlling an electric system including the rotation driving means. In this simplified toilet device, waste treatment tank or support The frame is provided with an exhaust fan that discharges the air in the waste disposal tank to the outside, for example, a deodorizer, and an air supply fan that blows air into the chips in the waste disposal tank. Humidity adjusting means for humidifying the chip is provided. Further, the stirring blade has an axis in the lower center of the waste treatment tank, and lifts up the chips stored therein from the bottom to agitate the chips and remove the waste dropped into the center. It is formed in a spiral shape that generates a circulating flow drawn inside.

As a result, since the stirring blade has a spiral shape, the chips and waste move from the outside to the inside while being spirally stirred, and move upward from the bottom to the inside of the waste treatment tank for stirring. It forms a circulating flow that falls down from the upper end of the blade. Therefore, the filth dropped into the refuse treatment tank rides on a flow that moves from the outside to the inside while being spirally stirred, and is eventually taken into the circulating flow, where it is sufficiently mixed with the chips. Become. Since such a circulating flow is generated to mix the chips and waste uniformly, the chips are not subjected to excessive impact force by the stirring blades.o

In addition, oxygen for activating aerobic microorganisms is added by an air supply fan that blows air into the chips in the waste treatment tank, and the injected waste is reduced by the microorganisms contained therein and the microorganisms attached to the chips. It is eaten and processed, almost all of which becomes gas and water. Microbial residues (compost) are treated by bacteria that eat it (eg, micro-micrococci). It is preferable that the bacteria that eat the residue of the microorganism be attached to the chip in advance.

Microorganisms that eat filth include unicellular bacteria belonging to eubacteria, multicellular actinomycetes, or algae, protozoa, fungi, etc. belonging to eukaryotes. Rarely, among these, those that have the ability to decompose filth into water or carbon dioxide while excreting enzymes, using filth consisting of manure as a nutrient source. Enzymes secreted into and out of the cells of microorganisms have the action of decomposing or synthesizing various substances and play a role as biological catalysts. The main enzymes produced by microorganisms include:-amylase, cellulase, maltase, perease, lactase, protease, lipase and the like.

It is also preferable to use wood chips (for example, cedar chips) as chips, but if it is a porous granular material that can support microorganisms, use synthetic resin materials, inorganic materials, or other materials. However, the present invention is applied.

Furthermore, the humidity inside the waste disposal tank was measured by humidity adjustment means to humidify the chips inside the waste disposal tank, and the temperature inside the waste disposal tank was set due to the effects of heating the chips and the frequency of using the simple toilet equipment. When the humidity reaches the lower limit, the solenoid valve opens automatically to supply water into the waste treatment tank. The humidity of the chips can also be adjusted by putting an appropriate amount of water into the waste disposal tank at a preset time. When the humidity inside the waste treatment tank gradually rises due to the supply of water and reaches the set upper limit of humidity, the solenoid valve closes automatically and the supply of water stops. For this reason, it is possible to maintain the humidity in the waste disposal tank within the optimal humidity range for the activity of microorganisms.

Further, in the simplified toilet device according to the present invention, a pseudo-arc-shaped notch or hole for dropping the scooped chips downward is provided on a radially inner portion of the spirally shaped stirring blade. A falling part may be formed.

In this case, the chips that have been scooped up from the lower part of the waste disposal tank by rotating the stirring blades are dropped from the falling part, are again scooped up by the stirring blades from the lower part, and circulate vertically. Being stirred Therefore, it is possible to improve the stirring efficiency.

In the simplified toilet device according to the present invention, the stirring blade may be provided with a heater for heating the chips to a predetermined temperature.

In this case, in order to promote both the activity of microorganisms that decompose dirt carried on the chip and the activity of microorganisms that extinguish generated microbial residues, and promote the decomposition and elimination of dirt, the chip must be It must be heated to 30 to 40 ° C. When heating the chips, instead of heating the entire waste disposal tank in which the chips are stored, the stirring blades that directly contact the chips are heated, and the chips are heated by heat transfer from the stirring blades. The heating method is the most efficient way to heat the chip. For this reason, a heater is installed on the stirring blade. In addition, if a temperature sensor is provided in the waste disposal tank and the temperature is controlled so that the chips are not heated more than necessary, the ability of microorganisms to treat waste can be stabilized at a high level.

In the simplified toilet device according to the present invention, a heater for heating the chip to a predetermined temperature may be provided at the bottom of the waste disposal tank.

In this case, the bottom of the waste disposal tank is formed as a double bottom consisting of an upper bottom plate and a lower bottom plate, and the upper bottom plate is formed of, for example, a stainless steel plate. By heating to 0 ° C., the structure for energizing the heat is simplified, and the weight of the stirring blade can be reduced.

In the simplified toilet device according to the present invention, a deodorizer may be provided downstream of the exhaust fan. As a result, the smell of the filth is treated and the unpleasant atmosphere is removed.

In the simplified toilet device according to the present invention, the deodorizer is disposed with an ultraviolet lamp in the center and a gap around the lamp, and the surface is coated with titanium oxide. It has a woven filter, and the exhaust gas from the exhaust fan may flow from outside to inside through the filter.

In this case, the malodorous component in the exhaust gas coated with a titanium oxide photocatalyst, for example, attached to a cylindrical filter, is evenly distributed by ultraviolet rays radiated from an ultraviolet lamp provided on the central axis of the filter. Moreover, since it is efficiently decomposed and released as an odorless component, the photocatalyst has a deodorizing function and can be used for a long time.

In the simplified toilet device according to the present invention, the toilet is a Western style toilet with a toilet seat, the support frame includes a backrest provided at a rear portion of the toilet seat, and the humidity adjusting means includes a water tank, An electromagnetic valve for turning on and off the water from the water tank, and a guide pipe for guiding water passing through the electromagnetic valve to the waste disposal tank may be provided, and the water tank may be disposed on the backrest.

In this case, it is possible to provide a friendly environment especially for the elderly and patients with physical disabilities, and to reduce the burden of care for caregivers. In addition, since the water tank is located on the backrest above the waste treatment tank, a drop occurs from the water tank to the waste treatment tank, and water is supplied from the water tank to the waste treatment tank without the need for a water supply pump. Can be.

In the simplified toilet device according to the present invention, all power including the power of the rotary drive means and the controller is supplied by a rechargeable battery, and the battery is provided by solar power, wind power, hydro power or fuel cell. It may be rechargeable.

Hereinafter, these will be described in detail.

The toilet 11 is, for example, a stainless steel toilet having a structure similar to that of a normal Japanese toilet. The type of toilet bowl can be the same as that of a normal Western style toilet bowl. The toilet bowl can be made of a material other than stainless steel, such as a hard plastic that is resistant to acid and water, and made of ceramic.

As shown in Figs. 3 and 4, the waste treatment tank 12 has an opening facing the waste discharge port formed at the bottom of the bottom plate 17, the side plate 18, and the lower part of the toilet bowl 11. It is made of, for example, a stainless steel cylindrical container having a lid 19 and is fixed below the toilet 11. The lid 19 is attached to a screw hole 21 on a flange 20 provided at the upper end of the side plate 18 by using a bolt. At the center of the bottom plate 17 of the waste treatment tank 12, a stirring blade 13 is mounted, for example, a rotary shaft 22 made of stainless steel is provided.The upper part of the rotary shaft 22 is located at the center of the lid 19. Protruding from an opening provided in the. A drive motor 23 and a reduction gear 24 attached to the output shaft of the drive motor 23 are provided on the outer surface of the side plate 18. A chain bracket 25 is provided below the protruding portion of the rotating shaft 22, and the chain sprocket 25 is connected to a reduction gear 24 via a chain 26.

Attached to form the stirring blade 13. The wing plate 27 has a part of the outer edge formed in an involute curve shape, and is attached with the cultivating shaft 22 as an axis so that the width is narrowed from the upper part to the lower part, and is curved at the inner edge part. A drop part 28 consisting of a pseudo-arc-shaped notch is formed, the radius of the largest diameter part of the slat 27 is slightly smaller than the inside diameter of the waste disposal tank 12, and the lowest part 29 is at the same height. It has a linear shape. A rib (side plate) 30 is provided on the outer upper part of the blade plate 27 in the enlarged diameter portion to reinforce the blade plate 27 and further forcibly prevent the raised chip 31 from dropping around. The tip 31 is stirred up to generate a rotating upward flow from the outside of the waste treatment tank 12 toward the center, and the upward flow is formed at the center at the inner edge. The chip 31 is dropped by reversing to a downward flow through the notch formed. In addition, the stirring blade 13 connects the lowermost portion 29 of the blade plate 27 and the boss 33 so as to rotate integrally with the reinforcing member 32, and the traveling direction of the reinforcing member 32 becomes lower. Thus, for example, a slope 32A inclined at about 40 degrees and a rear slope 32B behind the slope 32A are provided. This prevents the strength of the slats 27 from being reduced due to the formation of the falling portions 28 at the inner edge, and the chips 31 that have fallen to the center are gathered up by the slopes 32A. The lowermost part 29 is placed on the slat 27. In addition, the height H of the entire stirring blade 13 is low, and is disposed from the middle part to the bottom part of the waste disposal tank 12 so as to be completely hidden by the accumulated chips 31. The direction of the spiral of the blade plate 27 may be clockwise or counterclockwise, and the rotation direction of the stirring blade 13 may be changed accordingly.

In order to heat the chips 31 in the waste treatment tank 12, as shown in FIG. The plate 27 is provided so that the entire back surface thereof can be uniformly heated. Electric power is supplied to the heater 14 by a slip ring (not shown) provided on a boss 33 formed near the center of the rotating shaft 22 for mounting the blade 27. In order to optimize the heating of the chip 31 by the heater 14, a temperature sensor 134 for measuring the temperature in the waste treatment tank 12 is attached to the lower surface of the lid 19.

A swivel joint 35, which is an example of an air vent that blows external air sent from an air supply fan (not shown) into the waste treatment tank 12, is provided at a lower portion of the rotating shaft 22. It is provided in. Further, a swivel joint 37 as an example of an intake port for sucking gas from the waste disposal tank 12 1 is provided above the center of the rotating shaft 22. Swivel joint 3 One end of 7 is connected to one end of a communication pipe 38 formed to reach the upper end inside the rotating shaft 22. Further, a swivel joint 39 is provided above the rotating shaft 22 projecting from the lid 19 and connected to the other end of the communication pipe 38, and a pipe 40 is attached to the swivel joint 39, and a downstream side thereof is provided. Is equipped with an exhaust fan that exhausts the air in the waste treatment tank 12 (not shown) to the outside. As a result, oxygen necessary for the activity of microorganisms in the chip 31 can be efficiently supplied from outside, and carbon dioxide generated by the decomposition of waste by microorganisms is efficiently exhausted to the outside. And promote the decomposition of waste. Further, since the atmosphere in the waste treatment tank 12 is always replaced with fresh outside air, the odor generated in the waste treatment tank 12 can be removed.

As shown in FIG. 1, the humidity adjusting means 15 includes a humidity sensor 41 mounted on the lower surface of the lid 19, a water tank 42 for storing water used for humidity adjustment, a water supply, The electromagnetic valve 43 for stopping the operation and a guide tube connected to the electromagnetic valve 43 have a tip nozzle 44 for flowing water from the water tank 42 to generate water droplets from the tip. When the humidity in the waste disposal tank 1 2 measured by the humidity sensor 4 1 becomes less than the lower limit, the solenoid valve 4 3 opens and water is supplied from the water tank 4 2 to the tip nozzle 4 4, and the tip nozzle 4 4 The water is then dropped into the waste treatment tank 12 as water drops. When the water in the waste treatment tank 12 reaches the set upper limit due to water supply, the solenoid valve 43 closes and the water supply stops.

As shown in FIG. 6, the power supply section 16 has a solar cell 45, a wind power generator 46, a charger / discharger 47, and a storage battery 48. In the daytime, electricity generated by the solar battery 45 and electricity generated by the wind power generator 46 when wind is generated are charged and stored in the storage battery 48 via the charger / discharger 47 for simple operation. Type It is used for maintaining and operating power of the cooling device 10. In addition, the charger / discharger 47 has a function of preventing the storage battery 48 from being overcharged, detects the charge amount of the storage battery 48, and when the charge amount of the storage battery 48 reaches a predetermined amount. The electricity generated by the solar battery 45 and the wind power generator 46 is consumed by discharging. Next, a method of using the simplified toilet device 10 according to the first embodiment of the present invention will be described.

In the simplified toilet apparatus 10 according to the present invention, the heater 16, the humidity adjusting means 15, and the drive motor 23 are controlled to the operating state by the controller 16 A, and the stirring blade 13 is rotated. Keep it. Then, the filth dropped from above is dropped on a chip 31 (preferably a cedar chip) stored in a filth treatment tank 12 and buried in the chip 31 by rotation of the stirring blade 13. A heater 14 is attached to the back surface of the stirring blade 13 in contact with the chip 31 so that the heating of the chip 31 can be adjusted. In addition, fresh air was supplied from the outside to the waste treatment tank 12 from below the rotating shaft 22 to which the stirring blades 13 were attached, and generated inside the waste treatment tank 12 from above the rotating shaft 22. The gas is sucked, and the gas in the waste disposal tank 12 is replaced. Further, humidity control means 15 is provided in the waste treatment tank 12. Therefore, for the microorganisms in chip 31, an optimal temperature, humidity and oxygen environment for their activities is guaranteed.

For this reason, the input waste is decomposed by the microorganisms contained in the waste and the microorganisms carried on the chip 31, and almost all of the waste becomes carbon dioxide gas and water. In addition, since the chip 31 also carries microorganisms (eg, microscopic micrococci) that eat microbial residues (compost), the input waste is decomposed and completely disappeared. Microorganisms are added to chip 31. When the simple toilet apparatus 10 is used for the first time, it is sufficient to store the chips 31 in which the microorganisms are previously supported in the waste disposal tank 12 when the simple toilet apparatus 10 is used. The amount of chips 31 used at the start of use is about 2/3 of the volume of the waste disposal tank 12. The microorganisms are more active in a slightly humid state, so the chip 31 is slightly moistened.

As shown in FIG. 6, the simplified toilet device 10 operates with a power supply of 100 V. First, the water tank 42 for injecting water used for humidity adjustment is filled with water, and the switch of the power supply for operating the humidity adjusting means 15 is turned on. Thereby, the humidity adjustment is started based on the measurement by the humidity sensor 41 so that the humidity in the waste disposal tank 12 is in a range of, for example, 70 to 85%.

To use the toilet, open the door of the simple toilet device 10 and enter it and close it.When the door is closed, the stirring blades 13 in the waste disposal tank 12 rotate and the heat 14 starts heating. The supply fan and the exhaust fan start rotating. A timer is provided for each of the stirring blades 13, the heater 14, the air supply fan, and the exhaust fan, and is set so as to stop after a predetermined time has elapsed. The setting time of each timer 1 is set so that, for example, the stirring blade 13 is 2 minutes, the heater 14 and the air supply fan are 25 minutes, and the exhaust fan is 35 minutes. Under such setting conditions, the stirring blades 13 may stop during use of the toilet, depending on the usage time of the toilet. In addition, heaters 14, air supply fans, and exhaust fans continue to operate while the toilet is in use. Even when the timer of the heater 14 is counting, the temperature of the chip 31 is, for example, 30 to 40 ° based on the measurement by the temperature sensor 34 installed in the waste disposal tank 12. The heater 14 is turned on and off so as to be in the range of C, and the heating of the chip 31 is adjusted. When the use of the toilet is finished, open the door of the simple toilet device 10, go out, close the door, and the stirring blades 13 in the waste treatment tank 12 rotate again only for the set time of the timer 1. And stop. In addition, the operation of the heater 14, the air supply fan, and the exhaust fan is stopped by operating for a timer set from the initial startup when the door of the simple toilet apparatus 10 is opened. In addition, if the use of the toilet is finished before the stirring blade 13 started to start when entering the toilet does not stop, the opening and closing operation of the door when exiting the simplified toilet device 10 causes the stirring blade 13 to be closed. Operation is not affected, and the motor rotates and stops for the time set by the timer from the time of initial startup.

During and after use of the simplified toilet apparatus 10, the stirring blades 13 rotate for a predetermined time, the heaters 14 are heated, and the air supply and exhaust fans are activated, and the gas in the waste treatment tank 12 is activated. Make a substitution. As a result, the chip 31 is heated together with the waste and oxygen is supplied to the inside of the chip 31 to discharge carbon dioxide gas generated by the decomposition of the waste, thereby decomposing and eliminating the waste by microorganisms. Facilitate. In addition, a certain temperature is secured by the heat generated when microorganisms decompose filth.

Since the stirring blade 13 has a spiral shape, the chips 31 and the waste move from the outside to the inside while being spirally stirred, and move upward from the bottom in the waste treatment tank 12. Thus, a circulating flow of falling downward from the upper end of the stirring blade 13 is formed. Therefore, the filth dropped into the filth treatment tank 12 is mixed into a spiral and moves in a direction moving from the outside to the inside, eventually being taken into the circulating flow, and is sufficiently separated from the chips 31. Will be mixed. When the rotation of the stirring blades 13 is performed each time the simple toilet apparatus 10 is used, the filth is almost completely decomposed into microorganisms and becomes water (steam), carbon dioxide gas, and other gases, and further the residue of microorganisms is removed. other The waste is completely eliminated from between the chips 31 because it is eliminated by microorganisms.

Microorganisms that treat waste (eg, monococci, diplococci, streptococci, staphylococci, and other cocci; Bacillus subtilis, rhizobia, and other bacilli) are originally included in the waste, but must be treated once. If this is done, it will also adhere to the chip 31, and the subsequent waste disposal efficiency will improve. It is not necessary to replace the chips 3 1 stored in the waste disposal tank 1 2, but if wood chips are used, they will be decomposed by microorganisms to a small extent, so only the shortage will be added. . Next, as shown in FIGS. 7 to 9, the simplified toilet apparatus 50 according to the second embodiment of the present invention accommodates a chip 51 carrying microorganisms that decompose and extinguish waste.

It has a solar cell, a wind power generator, a charger / discharger, and a storage battery, and has similar functions and is controlled by the controller 59.

Here, a method of using the simplified toilet device 50 according to the second embodiment will be described.

Bacteria that eat bacteria residues are injected into the chip 51. It suffices to perform this operation the first time the simple toilet device 50 is used. About 2 Z 3 of the chip 51 is put in the waste treatment tank 52. The bacteria are more active if slightly moistened. If necessary, slightly moisten the chip 51. The deodorizer 58 must be equipped with a predetermined force cartridge 93.α

As shown in FIG. 13, the simple toilet apparatus 50 is entirely sequence-controlled by a controller 59 having a control means composed of, for example, a programmable sequencer, and operates with a power supply of 100 V ( Step S 1). First, the switches of all power supplies including the controller 59 are turned on (step S2). As a result, the exhaust fan 98 and the air supply fan 75 rotate, and the heater 67 and the ultraviolet lamp 95 are energized.

If, for example, two minutes have elapsed after the rotation of the stirring blades 55 (step S7), the operation switch of the drive motor 72 is set to ΔFF (step S8).

Owing to the rotation of the stirring blades 55, oxygen is supplied to the inside of the chip 51 containing the waste and is agitated, thereby promoting the decomposition of the waste by microorganisms. Since air is supplied into the chip 51 from the air blowing pipe 74 provided at the lower part of the waste treatment tank 52, the air comes into contact with the chip 51 in this process and enters the chip 51. Air will be taken in. Also, the temperature of about 30 to 40 ° C. is ensured by the heater 67 and the microorganisms eating the filth.

On the other hand, the chips 51 are agitated by the stirring blades 55, but since the chips 51 in the central part of the waste treatment tank 52 flow downstream, the waste dropped into the central part of the waste treatment tank 52 is immediately visible. Disappears. The rotation of the stirring blade 55 causes dirt to rise from the surroundings, but since the stirring blade 55 has a lower part 86, the scooped chips 51 drop down and become contaminated. Will not come to the surface of the pool of chips 51. Thereafter, when the toilet 53 is used (step S9), the operation from (step S4) is repeated.

If, for example, two minutes have passed since the rotation of the stirring blade 55 (step S12), the operation switch of the drive motor 72 is turned off to stop stirring (step S13). When the water supply reaches, for example, 100 cc by the solenoid valve 102 (step S14), the solenoid valve 102 is turned off and the water supply is stopped (step S15). It is also possible to change the water supply to 50 cc or 150 cc by changing the opening and closing time of the solenoid valve 102 depending on the size of the waste disposal tank 52, the amount of chips 51, or the frequency of use. is there.

Thereafter, when the toilet 53 is used (step S16), the operation from (step S4) is repeated. When the toilet 53 is not used until the time reaches 4 hours every 1 hour, that is, at the second, third, and fourth hours from the beginning, the operation returns to (Step S11) and the solenoid valve 102 and the drive module are returned. Turn ON 72 overnight to perform stirring and water supply (step S17) (step S18). After 4 hours, when the toilet 53 is used (step S19), the operation from (step S4) is repeated. If the toilet bowl 5 3 is not used until 8 hours have passed (step S 20), turn off the power switch and stop the heater 67, solenoid valve 102, exhaust fan 98, and air supply fan 75. (Step S21). After that, when the toilet 53 is used (Step S22), the operation returns to the start (Step S1) to resume the operation.

When the rotation of the stirring blades 55 is performed for about 1 to 3 hours (step S10), the waste is almost completely eaten by the microorganisms and becomes gas such as water (water vapor) and carbon dioxide, and is completely chipped. 5 Eliminated from within 1. In addition, microorganisms that process waste (feces) (eg, monococci, diplococci, streptococci, cocci such as staphylococci, and bacilli such as Bacillus subtilis, rhizobia, etc.) are originally contained in the waste. If the treatment is performed once, it adheres to the chip 51, so that the efficiency of the treatment of the subsequent waste is improved. The disposal of sewage produces microbial residues, which are eaten by other micro-organisms (ie, micro-organisms attached to chip 51) and eventually eliminated.

There is no need to replace the chip 51 once it has been charged in the waste treatment tank 52 in a predetermined amount.However, if wood chips are used, they will be eaten by microorganisms in a small area, so only the shortage will be used. Will be added.
