Description

[Technical Field]

[0001] The present invention relates to a portable toilet that can be used appropriately when flush toilets cannot be used, for example, during a disaster. [Background technology]

[0002] When the water supply and sewerage systems stop functioning due to a disaster such as an earthquake, flush toilets become unusable. In such a situation, emergency toilets are available that can be attached to existing toilets. These emergency toilets have a bag-shaped storage compartment for storing excrement, which is attached to the seat of the existing toilet or between the toilet bowl and the seat. Multiple storage compartments are stacked on top of each other. Each time a user uses the toilet, they remove the top storage compartment and discard the excrement stored therein. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-81564 [Patent Document 2] Patent No. 5522833 DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0004] The emergency toilet disclosed in the patent document requires the cumbersome task of removing the storage compartments after each use, such as by separating them. Furthermore, the emergency toilet disclosed in the patent document is used by stacking multiple storage compartments, with excrement accumulating in the topmost storage compartment. After use, the topmost storage compartment is separated, and the compartment that was originally second from the top becomes the topmost, ready for use the next time. Therefore, it is necessary to prevent excrement from accumulating in the topmost storage compartment and then passing through the storage compartments to reach the second-highest storage compartment before separation. Therefore, the storage compartments must be made of a water-impermeable material, such as vinyl. Such materials pose problems such as CO2 reduction and environmental destruction.

[0005] Furthermore, the emergency toilets disclosed in the patent documents require disposal of the storage compartment, but some municipalities do not allow waste to be disposed of as combustible waste. In the case of a temporary water outage, the waste stored in the storage compartment can be flushed down the toilet after the water supply and sewerage system is restored. However, in the case of a long-term water outage, such as during a disaster, many storage compartments containing waste from each use will accumulate, making disposal difficult.

[0006] The above-mentioned problems are described as being independent of each other, and the present invention does not necessarily have to solve all of the problems described, but it is sufficient if it can solve at least one of the problems. Furthermore, we intend to obtain rights to the configurations for solving these problems separately through divisional applications, amendments, etc. [Means for solving the problem]

[0007] (1) The portable toilet of the present invention comprises a toilet bowl, a first storage section arranged below the toilet bowl for temporarily storing feces while performing a predetermined process, and a second storage section for storing the processed material discharged from the first storage section. The portable toilet also comprises an agitator blade attached to a rotating shaft arranged to cross the storage space of the first storage section, and a spring for rotating the rotating shaft. The storage space is configured so that chip material made of materials that can be returned to the soil can be filled, and the predetermined process is a process in which the chip material and the feces are agitated and mixed by the agitator blade.

[0008] (2) The chip material may be activated carbon made from a material that returns to the soil.

[0009] (3) The first storage section may be configured so that sawdust can be supplied together with the chips.

[0010] (4) The mainspring may be configured to be linked to both ends of the rotary shaft.

[0011] (5) The second storage section may have a space located below the first storage section, a conveying member movably arranged in the space, and a storage bag placed on the conveying member with its top open, and may be configured so that the material to be processed is dropped from the first storage section into the storage bag.

[0012] (6) It is preferable that a heating element is provided around the outer periphery of the storage bag.

[0013] (7) A lid member that can be opened and closed is placed below the toilet bowl, and the feces stored in the first storage section are collected by an excrement collector attached to the toilet bowl. The lid member is opened and the excrement collector is dropped into the first storage section, and the excrement collector is preferably made of a material that can be recycled to the soil.

[0014] Furthermore, the configurations shown in (1) to (7) above can be configured by combining them as appropriate, and based on such combined configurations, it is advisable to combine the components described in the embodiments and drawings. [Effects of the Invention]

[0015] The present invention can achieve at least one of the following effects: It eliminates the need for tasks such as storing excrement in a bag and sealing the opening each time a person defecates. It eliminates the need for plastic bags containing excrement to accumulate each time a person defecates, which creates a sense of discomfort and eliminates psychological stress. It enables environmentally friendly disposal. It is useful for people who are evacuated to their homes during disasters, even when lifelines such as water are cut off. [Brief explanation of the drawings]

[0016] [Figure 1] 1A and 1B are diagrams showing a preferred embodiment of a urine collecting device of the present invention. [Figure 2] FIG. 2 is a diagram showing an example of an excrement collector 40. [Figure 3] FIG. [Figure 4] FIG. DETAILED DESCRIPTION OF THE INVENTION

[0017] Preferred embodiments of the present invention will be described in detail below with reference to the drawings. However, the present invention is not limited to these embodiments, and various changes, modifications, and improvements can be made based on the knowledge of those skilled in the art without departing from the scope of the present invention.

[0018] FIG. 1 is a diagram showing a preferred embodiment of a portable toilet according to the present invention. The diagram is a schematic diagram showing the relative positions of various components, and the size relationships and dimensions of the various components in the diagram may differ from those in reality. The portable toilet 10 of this embodiment has a case body 11 divided into two parts, upper and lower. The case body 11 has a first case section 12 (an example of a first storage section) located at the top and a second case section 13 (an example of a second storage section) located at the bottom.

[0019] The first case 12 has a hollow box shape and is provided with a toilet bowl 15 on the top surface 12a side. In the illustrated example, a portion of the top surface 12a is configured as the toilet bowl 15 by forming a recess by depressing the center of the top surface 12a downward, or a toilet prepared as a separate member may be set on the top surface 12a. The toilet bowl 15 may also be provided with a mechanism for discharging excreted urine and feces separately.

[0020] Additionally, a toilet seat 16 is provided above the toilet bowl 15, and a toilet seat cover (not shown) may be provided on top of the toilet seat 16. As with a typical Western-style toilet, the toilet seat 16 and the toilet seat cover open and close based on one end. Figure 1 shows the toilet in use, with the toilet seat 16 placed on top of the toilet bowl 15 and the toilet seat cover (not shown) raised to open the top of the toilet bowl 15.

[0021] The central lower end of the toilet bowl 15 has a first opening 17 that penetrates vertically. A first bottom lid 18 that opens and closes the first opening 17 is provided around the periphery of the first opening 17. In the example shown, the first bottom lid 18 is divided into two parts that open and close like a double door, but it may also be constructed as a single piece. In addition, in the normal state, the first bottom lid 18 is positioned so as to close the first opening 17, as shown by the solid line. When the first bottom lid 18 is in this closed position, the space of the first case 12 and the space of the second case 13 are closed and separated.

[0022] Furthermore, a predetermined gasket may be provided on the periphery of the first bottom cover 18, the top surface 12a, or the periphery of the first opening 17 of the toilet bowl 15, so that when the first bottom cover 18 is closed, the gasket tightly contacts the gasket, sealing the first opening 17. As described below, the space within the first case 12 forms a first storage section that temporarily stores excrement while performing a predetermined process, so it is preferable to prevent the odor of the stored excrement from leaking to the outside. Furthermore, if the first bottom cover 18 is a two-part door with double doors or is divided into three or more parts, it is preferable to configure the contact areas between the parts when closed with gaskets or other structures to tightly seal them. Furthermore, the first bottom cover 18 is not limited to being opened and closed by rotating forward and backward in a vertical plane based on the upper end as described above, but can be configured to open and close by moving in a horizontal plane, for example.

[0023] The first bottom cover 18 may be operated via a power transmission mechanism such as a predetermined link mechanism or rotation mechanism based on the operation of an operating lever (not shown) provided at a predetermined position on the first case 12. In this way, the first bottom cover 18, which is connected by a mechanical mechanism, opens and closes based on the operation of the operating lever, so that it can be operated even when the power supply is cut off during a disaster. The operating lever may be, for example, a foot pedal. Alternatively, a drive motor may be built in, and the drive motor may be operated based on the operation of a switch to electrically open and close the first bottom cover 18. In this case, the drive motor may be configured to be powered by a battery or the like.

[0024] In addition, both side surfaces 12b of first case portion 12 are configured to support the vicinity of both ends of rotating shaft 19 as bearings. A plurality of stirring blade portions 20 are attached to rotating shaft 19. In addition, a spring portion 21 is arranged at a predetermined position on the inner surface of side surface 12b of first case portion 12 (near the bearing portion that supports rotating shaft 19). Spring portion 21 is configured, for example, by housing a spring in a predetermined case, and one end of the spring is connected to rotating shaft 19.

[0025] One end of the rotating shaft 19 is configured to protrude a predetermined distance outside the side surface 12b of the first case portion 12. A handle portion 22 is connected to the tip of the protruding side of the rotating shaft 19. As a result, when a user turns the handle portion 22 so as to rotate around the rotating shaft 19, the agitating blade portion 20 also rotates in response to the rotation of the rotating shaft 19. Furthermore, the spring of the spring portion 21, which is connected to both ends of the rotating shaft 19, is also wound. Then, when the rotation of the handle portion 22 is released, the wound spring attempts to return to its original position due to its elastic force, rotating the rotating shaft 19 in the reverse direction. As a result, the rotating shaft 19, and therefore the agitating blade portion 20, rotates until the elastic restoring force of the spring is lost.

[0026] The first case portion 12 also has a second opening 24 that penetrates vertically at the center of the bottom surface 12c. A second bottom cover portion 26 that opens and closes the second opening 24 is provided at a predetermined position on the outer surface of the bottom surface 12c. The second bottom cover portion 26 is composed of a single member or multiple separate members, similar to the first bottom cover portion 18. The second bottom cover portion 26 is configured to open and close using a predetermined drive mechanism, such as a mechanical or electric drive mechanism. Furthermore, the second bottom cover portion 26 is positioned so as to close the second opening 24 in the normal state, as shown by the solid line.

[0027] The second case portion 13 is hollow and box-shaped, and has a third opening 27 on one side surface 13a, as well as a door portion 28 that opens and closes the third opening 27. In this embodiment, the door portion 28 has a hinge portion at the top end and is configured to be opened and closed manually.

[0028] Furthermore, a tray 29 (an example of a tray) with casters that moves on the bottom surface 13b is stored inside the second case portion 13. A storage bag 30 with its top open is set on the tray 29. Although not shown, it is advisable to provide a support frame or the like at a predetermined position on the periphery of the top surface of the tray 29 to hold the storage bag 30 in a position with its top widely open.

[0029] Furthermore, in this embodiment, a predetermined excrement collector 40 is set in the toilet bowl 15. As shown in Figure 2, the excrement collector 40 comprises a recessed collection section 41 capable of collecting excrement, and band sections 42 provided on the left and right sides of the collection section 41. The band section 42 has an opening cut out in the center, and is formed in a roughly square shape in plan view. The underside of the tip of the band section 42 is provided with an adhesive area 43, such as double-sided adhesive tape.

[0030] The collection portion 41 of this embodiment includes a first recess 44 recessed downward from the outer periphery, and a second recess 45 further recessed in the center of the bottom 44a of the first recess 44. The first recess 44 has a generally truncated pyramid shape tapered at the bottom. Similarly, the second recess 45 also has a generally truncated pyramid shape tapered at the bottom, and its bottom 45a is a generally rectangular flat surface.

[0031] The shapes of the collection portion 41 and the band portion 42 are not limited to those shown in the drawings and may take various other shapes. Furthermore, the band portion 42 is not limited to extending left and right as shown in the drawings, and may further include a band portion that extends forward or backward, for example.

[0032] The collection portion 41 and band portion 42 are formed, for example, by appropriately overlapping sheets of a predetermined material. The predetermined material sheets may be made of, for example, a biodegradable material. The material may be made of various materials, such as biodegradable paper or biodegradable plastic. The excrement collection tool 40 is formed by punching out a laminated sheet made by appropriately overlapping layers of material sheets made of a biodegradable material into the desired shape and simultaneously molding the laminated sheet by hot pressing, thereby integrally forming the concave collection portion 41 and band portion 42, as shown in FIG. 2. It is preferable to impregnate (impregnate) the material sheets or excrement collection tool 40 with a deodorizer, a fermentation promoter, or the like before, during, or after the hot pressing process.

[0033] The excrement collector 40 having the above-described configuration is fixed by attaching the adhesive portion 43 provided at the tip of the band portion 42 to the upper left and right surfaces of the sit-down toilet bowl portion 15 or the upper left and right surfaces of the toilet seat portion 16.

[0034] The portable toilet 10 configured as described above can be used, for example, as follows. First, as shown in FIG. 3(a), a predetermined amount of chip material 33 is filled into the first case 12 in advance. The chip material 33 is preferably supplied up to a position where the agitator blade 20 is buried. The chip material 33 can be activated carbon made of a soil-recyclable material. The chip material 33 can also be made of the same soil-recyclable material as the excrement collector 40. In this case, activated carbon can be used, but a cotton-like material is also preferable. The cotton-like chip material can be, for example, a laminated sheet formed by stacking multiple sheets of the soil-recyclable material, which is crushed and shredded into fibers in a crusher, resulting in the individual fibers becoming entangled and cotton-like. The laminated sheet to be crushed can also be scraps generated during the manufacture of the excrement collector 40, i.e., the remaining parts separated from the excrement collector 40 by a punch press. In this way, waste generation can be reduced and the SDGs can be achieved. Furthermore, it is advisable to add a deodorizer, a fermentation promoter, or the like to the chip material 33.

[0035] In addition, the chip material 33 may be supplied, for example, by opening the first bottom cover portion 18 and supplying it through the first opening 17, but it is preferable to provide an inlet (preferably openable / closable) at a predetermined position, such as the side surface 12b of the first case portion 12, and supply the chip material through the inlet.

[0036] Furthermore, prior to use, the user should sprinkle chip material 33 over the toilet bowl 15 with the toilet seat cover open, and place the chip material 33 on the first bottom lid 18 as well, as shown in Figure 3(a). In this way, soiling of the first bottom lid 18 can be minimized.

[0037] When the user actually defecates, the user takes out one of the excrement collectors 40 and attaches and fixes the adhesive portion 43 provided at the tip of the band portion 42 to the left and right upper surfaces of the sit-down toilet bowl portion 15 or the left and right upper surfaces of the toilet seat portion 16.

[0038] The user then sits on the toilet seat 16 and defecates. The feces excreted by the user are then collected in the collection section 41 of the excrement collector 40. As shown in FIG. 3(b), after excretion, the user sprinkles chipping material 33 on the feces 36 collected in the excrement collector 40. This chipping material 33 can be made, for example, from crushed scraps produced during the manufacture of the excrement collector 40. In this way, the excrement collected in the collection section 41 can be surrounded by the material that makes up the excrement collector 40, i.e., the biodegradable material. Furthermore, the material that makes up the excrement collector 40 is based on a biodegradable material, and predetermined additives such as deodorizers are added, allowing the additives to exert their effects.

[0039] As shown in Figure 3(c), after the user has finished excreting, the user opens the first bottom lid 18. The user also removes the excrement collector 40 from the toilet bowl 15 or toilet seat 16 and discards the removed excrement collector 40 into the toilet bowl 15. As a result, the excrement collector 40, with the stool 36 still stored in the collection portion 41, passes through the first opening 17 and drops into the first case portion 12.

[0040] The user then rotates the handle 22 a predetermined number of times. As a result, the agitating blade 20 rotates around the rotary shaft 19, agitating the tip material 33 previously packed inside the first case 12 and the excrement collector 40 containing the stool. As a result of this agitation, the excrement collector 40 is cut into small pieces, and the small pieces and stool are mixed with the tip material 33.

[0041] As the handle 22 is operated, the spring 21 is wound. When the user releases the handle 22 at the appropriate time, the spring's restoring force causes the agitating blade 20 to rotate in the opposite direction. After the user defecates, they drop the excrement collector 40 into the first case 12, operate the handle 22 to wind the spring, and then leave the toilet and resume their normal activities. While the user continues to live their normal activities, the agitating blade 20 continues to rotate due to the force of the spring, agitating the chip material 33, the materials constituting the excrement collector 40, and the feces. This rotational period may be, for example, one to two hours. Because two springs 21 are provided, the chip material 33 is light, and the agitating blade 20 only needs to rotate slowly, the agitating blade 20 can rotate for a relatively long time. During this agitation process, the feces are fermented and decomposed by the action of microorganisms.

[0042] When the spring breaks, the rotation of the stirring blade portion 20 stops, but the chip material 33, the constituent materials of the excrement collector 40, and the feces remain in a suitably mixed state in the first case portion 12, and fermentation and decomposition proceed.

[0043] The portable toilet 10 of this embodiment is installed, for example, in a private home. Therefore, the above-described process is repeated each time a resident of the home uses the toilet. Thus, each time the resident disposes of excrement, the excreted feces 36 are added to the first case portion 12 together with the excrement collector 40. After a predetermined period, for example, one to three days, the user opens the second bottom lid portion 26 (see FIG. 3(d)). This causes the treated material 37, consisting of the mixed feces and chips that have been processed in the first case portion 12 during the predetermined period, to fall through the second opening 24 into the second case portion 13 below. The treated material 37 is then placed in a storage bag 30 placed on a tray 29 within the second case portion 13.

[0044] 3(d) shows that when the second bottom lid portion 26 is opened, all of the chip material 33, feces, etc. that were in the first case portion 12 are transferred to the storage bag 30 below, but some may remain in the first case portion 12. This remaining material can be used to mix with the feces that will be supplied with the excrement collector 40 from the next time onwards.

[0045] Once the storage bag 30 is filled with the agitated and mixed chip material 33 and feces, etc., the second bottom lid 26 is closed. Then, the chip material 33 is filled and supplied into the first case 12 so that the agitating blade 20 is buried. This allows for new defecation treatment. The above process is then repeated as appropriate, and once a certain amount of the mixed chip material 33 and feces, etc., has accumulated in the storage bag 30, or after a predetermined number of days have passed, the door 28 is opened and the tray 29 is pulled out. The user then removes the storage bag 30 and performs the desired treatment.

[0046] The predetermined disposal may be, for example, placing the entire storage bag 30 on a predetermined surface or burying it. Alternatively, the contents stored in the storage bag 30 may be removed from the storage bag 30 and placed on a predetermined surface or buried.

[0047] As described above, stirring and mixing promotes fermentation and decomposition, resulting in fertilizer formation. Even if the waste does not become compost while stored in the portable toilet 10, it will function as compost after a certain period of time if placed in a location where compost is needed or in a storage facility. Furthermore, the chips 33, excrement collector 40, and storage bag 30 are all made of materials that return to the soil, so even if they are left on the ground or underground, they will return to the soil and will not cause environmental damage. Therefore, the portable toilet 10 of this embodiment is environmentally friendly.

[0048] In the above-described embodiment, the first case portion 12 is filled with the chip material 33, but it is also preferable to mix in natural materials such as sawdust, as this will further promote fermentation and decomposition.

[0049] As shown in FIG. 4, it is also advisable to place heating elements 35 around the storage bag 30. The side walls of the tray 29 are raised, and the heating elements 35 are attached to predetermined positions on the bottom surface 29a and side surfaces 29b. The heating elements 35 may be, for example, disposable hand warmers. In this way, the chip material 33 and feces in the storage bag 30 are heated from the surroundings, raising their temperature, and can be fermented and decomposed by utilizing the action of microorganisms. If a disposable hand warmer is used as the heating element 35, it can be reused as a deodorizer after use.

[0050] If you use disposable hand warmers, it is best to choose ones that can be used continuously for a long time, such as 20 hours. This way, you don't need to replace them and you can continue fermenting for a long time.
