Description

This invention relates to toilet units.

Toilet units used in areas where there is no sewage system transfer wastewater from the used toilet bowl to a wastewater tank. If the sewage tank is directly under the toilet bowl, the sewage can be dropped as it is, but the odor will rise directly from the sewage tank. Therefore, in some cases, a structure is employed in which a region is formed below the toilet bowl to be constantly filled with water, and once a pipe is raised from that region, it is connected to the sewage tank.

Due to such a piping structure, it is necessary to apply a certain amount of pressure to the sewage. Although there is a method of flushing with a large amount of water, it is desirable to save the flushing water used as much as possible because the location where the toilet unit must be installed is often a place without water supply.

On the other hand, in order to drain dirty water from the toilet bowl while saving water, it is conceivable to use a pump. For example, Patent Literature 1 proposes a water-saving toilet that is provided with a pressure-feeding discharge mechanism 5 interposed with a discharge pump to pressure-feed and discharge waste water (washing water + waste) to be discharged, thereby reducing the amount of water used for washing. ing. Japanese Patent Application Laid-Open No. 2002-200002 also proposes drainage by the pump 24 .

On the other hand, as a portable toilet that can be used not only in the sewage system but also in situations where a sewage tank cannot be prepared, Patent Document 3 proposes packaging excrement with a thermoplastic resin film using a sealing device provided under the toilet seat. there is

JP 2018-059306 A Japanese Patent Application Laid-Open No. 2021-31867 JP 2019-4933 A

However, the mechanism of the portable toilet described in Patent Document 3 could not be incorporated into a flush toilet due to the structure in which a sealing device is provided under the toilet seat and the toilet seat is received with a film bag.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to enable disposal of excrement while using a flush toilet without using a sewage tank or a sewage system.

This invention
a toilet for delivering flush water;
a suction device for sucking sewage from the toilet;
a pack device provided below the suction device;
has
The suction device is
a suction port to which a drain pipe extending from the toilet bowl is connected;
a discharge port provided below;
has
The pack device is
The toilet unit, which packages and seals the sewage discharged from the outlet, solves the above problems.

That is, a toilet bowl that can be washed with flush water is provided with a suction device that sucks dirty water through a drain pipe extending from the toilet bowl, and the excrement stored in the flush toilet bowl and flushed flush water are sucked together, and the suction device is used. By arranging the packing device directly below, we realized packaging with a flush toilet.

Furthermore, the toilet unit according to the present invention is
The suction device is
a temporary tank that can temporarily store the sewage sucked from the suction port;
a suction mechanism for discharging the gas in the temporary tank to generate a suction pressure;
a discharge port provided below the temporary tank;
an openable and closable lid capable of sealing the outlet;
has
A structure in which a suction port connected to the suction mechanism is arranged above the suction port can be adopted. Since the sucked excrement and washing water can be temporarily stored in a tank and then dropped all at once and packaged, the timing of packaging can be easily controlled, and the amount of waste water remaining in the suction device can be suppressed, which makes it possible to further increase the efficiency. Efficient operation and less odor.

By adopting this structure and providing a suction port connected to the suction mechanism above the suction port, the dirty water sucked from the suction port does not reach the suction mechanism unless the temporary tank is full. not reach. If the capacity of the temporary tank is secured to the extent that the once sucked dirty water can be temporarily accommodated, even if all the dirty water generated in one use is sucked, the dirty water will not reach the suction mechanism itself without being sucked. . By opening the lid of the discharge port provided below the temporary tank when the necessary amount of dirty water has been sucked in, the dirty water can be transferred to the pack device below without reaching the suction mechanism, so that the suction mechanism draws out the dirty water. No need to inhale. The suction port may be located above the suction port, the suction mechanism itself may be disposed above the suction port, or the suction mechanism itself connected to the suction port by a suction pipe may It may be arranged below the suction port. This eliminates the need for maintenance such as providing a filter in the suction mechanism and replacing it, and the suction mechanism, which includes fragile parts such as bearings, is not immersed in dirty water. It is possible to almost prevent deterioration due to sewage. As a result, even in environments where repair is difficult, such as during disasters when packaging is particularly required, and where toilet users are concentrated and overused, it is difficult to break down and stable operation is possible.

In the toilet unit according to this invention,
the outlet having a closing mechanism that biases the lid closed;
It is possible to adopt an embodiment in which the load applied by the closing mechanism is adjusted so that the lid is opened by the weight of the sewage when a predetermined amount of sewage is accumulated in the temporary tank. In this embodiment, while the dirty water is being sucked, the urging force by the closing mechanism and the suction force by the suction mechanism are combined to continue sucking without opening the lid for a while even if the dirty water is added. be able to. When a predetermined amount of dirty water accumulates in the temporary tank, a load exceeding the urging force and the suction force of the closing mechanism is applied, and the lid is adjusted to open. This can be done automatically in conjunction, and the dropping into the pack device can proceed smoothly. These operations can be performed without electronic time measurement or control based on sensor information. It is particularly desirable in a harsh installation environment where the switchgear is prone to errors, and is less likely to fail even during long-term operation in the event of a disaster.

In the toilet unit according to the present invention, the heat-sealing means for heat-sealing and sealing the cylindrical thermoplastic resin film at two locations separated in the lengthwise direction of the cylinder; A structure having cutting means for cutting in the circumferential direction can be adopted. The cylinder length direction is the length direction of the tubular film, and the circumferential direction is the circumferential direction of the tubular film. Since the heat-sealed portion is actually in the form of a sheet, the circumferential direction corresponds to the width direction of the sheet. Sealing is possible by heat-sealing the thermoplastic resin, and by using a cylindrical thermoplastic resin film, it is possible to proceed with packaging sequentially and dispose of it as a small pack from the end. becomes.

As another form of the toilet unit according to the present invention, a structure having heat welding means for heat-sealing and sealing a tubular thermoplastic resin film can be employed. Sealing is made possible by heat-sealing the thermoplastic resin, and by using a cylindrical thermoplastic resin film, packaging is gradually promoted, and a continuous pack in which the waste is individually packed from the end. It is possible to dispose of the Furthermore, in the toilet unit according to the present invention, a structure having cutting means for cutting in the circumferential direction the portion heat-welded by the heat-welding means may be employed.

In another embodiment of the toilet unit according to the present invention,
A control device capable of controlling opening and closing of the lid and operation/stop of the suction mechanism,
The control device is
closing the lid;
After operating the suction mechanism, sucking the dirty water from the toilet bowl and completely sucking it from the drain pipe, stopping the suction mechanism,
Simultaneously with or after this stop, the lid is opened to drop the dirty water stored in the temporary tank into the packing device,
An embodiment can be employed in which heat welding is performed by the heat welding means after the drop.
In this embodiment, the opening of the lid and the subsequent heat welding and cutting are timed by the controller. Suction and dropping of sewage into a temporary tank can be performed at a reliable timing, and then packaging can be performed at a precise timing. It is preferable if the cost of the controller is acceptable and if the controller is in an environment where it is not prone to errors.

Furthermore, in this embodiment, an embodiment in which the heat welding and the cutting by the cutting means are performed simultaneously or after the heat welding can be adopted. At the right time, the package can be divided into small portions and separated from the tubular thermoplastic resin film for individual disposal.

Using the toilet unit of the present invention, a suction device and a packing device installed separately from the toilet bowl rather than under the toilet bowl package the excrement and waste after washing even though it is a flush toilet using flush water. can be discarded. This makes it possible to provide a comfortable environment in which flush toilets can be used as long as water can be replenished from rainwater or other sources, even in times of disaster when wastewater treatment is likely to be difficult. can do. In addition, even in nursing care sites where it was difficult to install a flush toilet in the past, it will be possible to package the generated waste and treat it hygienically while installing a flush toilet.

Hereinafter, the present invention will be described with reference to specific embodiments. FIG. 1(a) shows a side sectional view of a toilet unit 11 according to the first embodiment. It should be noted that the suction device 16 and the pack device 13 are drawn larger than the actual size ratio for functional illustration.

A toilet unit 11 according to this embodiment is provided with a toilet bowl 12 that can be flushed by sending flush water. Although the drawings show an embodiment having one Western-style toilet, it may be a Japanese-style toilet or a male urinal. However, since once-stored excrement is sucked together with flushing water, a Japanese-style or Western-style toilet is easier to operate. Washing water is ejected from the nozzle 23 only when it is mechanically or electronically operated when necessary. However, those valves, operation parts, etc. are omitted here. The washing water to be supplied to the nozzle 23 can be obtained by connecting the source of the nozzle 23 to the water supply when tap water is available, normally closing it with a valve, and opening the valve by an electromagnetic valve or physical operation. Available. If tap water cannot be used, a cleaning water tank storing rainwater, purified water, and other pumped water can be prepared, and a structure can be used in which water is supplied to the nozzle 23 from this cleaning water tank by a pump. . In this case, washing water is spouted from the nozzle 23 by operating this pump. Although the following description will be described using pump operation as an example, the present invention is not limited to this.

Water is stored in the toilet bowl 12 . When used, it becomes dirty water P containing excrement and washing water. A lower portion of the toilet bowl 12 is connected to a drain pipe 25 . Although not shown, it is preferable to provide a check valve at the drain pipe 25 or at a connection therewith to prevent backflow. In order to maintain the water surface in the toilet bowl 12 , the drain pipe 25 once passes through a position higher than the water surface of the toilet bowl 12 or reaches a position higher than the water surface of the toilet bowl 12 . The end of the drain pipe 25 is connected to the suction port 31 of the suction device 16 . The suction device 16 is driven in conjunction with jetting of cleansing water from the nozzle 23 to suck the dirty water P from the toilet bowl 12 .

The sewage P sucked by the suction device 16 is packaged and sealed by a packing device 13 provided below the suction device 16.例文帳に追加Packaging is stuffing into a bag so that it can be handled as a block without leaking for the time being. Although the method of packaging is not limited, it is preferable to use a bag made of a thermoplastic resin film and seal it by heat welding. It is more preferable that the odor is prevented from leaking.

A structural example of the suction device 16 is shown in FIG. The suction device 16 includes a suction port 31 to which a drain pipe 25 extending from the toilet bowl 12 is connected, a temporary tank 32 that can temporarily store sewage P sucked from the suction port 31, and a gas in the temporary tank 32 that is discharged. It has a suction mechanism 33 for generating a suction pressure, a discharge port 34 provided below the temporary tank 32 and an openable/closable lid 35 capable of sealing the discharge port 34 .

The suction port 31 is connected to the drain pipe 25 in a sealed manner so as not to create a gap through which air leaks. This is because the suction pressure by the suction mechanism 33 is not lowered.

The temporary tank 32 has a temporary holding capacity that is greater than the flush water used for one batch of toilet bowl 12 . Specifically, it has a temporary storage capacity that is larger than the capacity obtained by adding the amount of waste that is expected to be added in addition to the amount of washing water used for one time. This is because it is necessary to be able to temporarily accommodate a single dose of combined wash water and waste. Although it is not limited, if about 3 liters is secured, there is generally no problem in operation. Here, the temporary storage capacity of the temporary tank 32 is the capacity located below the lower edge 31 a of the suction port 31 . If the water level rises above the lower edge 31a of the suction port 31, there is a risk of backflow from the suction port 31 to the toilet bowl 12, so the space above the edge 31a is introduced into the discharge port 34. Useless for temporary containment until In addition, since the amount stored for each use is discharged from the discharge port 34, which will be described later, it is not necessary to secure a temporary storage capacity that exceeds the amount used twice.

The suction mechanism 33 discharges the gas in the temporary tank 32, and as a specific configuration, it includes a motor 51, a rotating shaft 54 connected to the motor 51, and a fan 52 installed around the rotating shaft 54. , 53, a suction chamber 55 housing fans 52 and 53, and an exhaust port 56 for exhausting gas. The configuration of the fans 52 and 53 housed in the suction chamber 55 is not particularly limited, but if there is only a single fan, air may enter through gaps and the suction force may be insufficient. For this reason, it is desirable to employ a fan with high sealing performance, such as a combination of a rotating fan 53 and a fixed fan 52, as illustrated in the developed view of FIG. 2(b). The suction mechanism 33 is not limited to the exemplified form, and is not particularly limited as long as it can generate suction pressure to the extent that vacuum suction can be performed.

However, the suction port 48 connected to the suction mechanism 33 needs to be arranged above the suction port 31 . Being above means that the lowermost position of the gas sucking portion of the suction mechanism 33 is above the position of the lower edge 31 a of the suction port 31 . Such arrangement can substantially prevent the sewage P sucked from the suction port 31 from being sucked into the suction mechanism 33 . More desirably, the lowermost position of the suction port 48 is above the position of the upper edge 31 b of the suction port 31 . In the embodiment of FIG. 2( a ), the entire suction mechanism 33 is arranged above the position of the upper edge 31 b of the suction port 31 . Note that the suction mechanism 33 itself may be located below the suction port 31 as long as the suction port 48 is above the suction port 31 . An example of such an embodiment is shown in FIG. 2(c). The tip of the suction port 48 is connected to a hose-like suction pipe 49 and is connected to a connection port 50 which is a suction port on the side of the suction mechanism 33 .

In any of the above forms, the suction port 48 is arranged above the suction port 31, so that the suction mechanism 33 does not suck the dirty water P, so that the fans 52 and 53 and the motor 51 of the suction mechanism 33 are not dirty. There is no need to install a filter or the like to prevent This eliminates the need for periodic filter cleaning maintenance, prevents a reduction in suction pressure due to the intervention of the filter, and allows the toilet unit to be operated with stable output.

The discharge port 34 is provided below the temporary tank 32 to drop the sewage P temporarily stored in the temporary tank 32 to the packing device 13 . The lower part of the temporary tank 32 means a position where the sewage P at the bottom of the temporary tank 32 can also be discharged, but it is preferable that it is provided facing downward on the bottom surface of the tank for structural reasons.

An enlarged view of the first embodiment is shown in FIG. 3(a). A lid 35 provided on the discharge port 34 can seal and close the discharge port 34, and can also be opened. Here, sealing means that when the cover 35 is closed, the sewage P does not fall into the packing device 13, and the airtightness and watertightness to the extent that the sewage P can be kept in the temporary tank 32 can be secured. Leakage may be such that most of it stays while some falls off. However, it is desirable that airtightness and watertightness are high.

As a mechanism for closing the lid 35, for example, a first embodiment in which an opening and closing device 41 is electrically driven by a motor or the like according to an instruction from a control device 45, and a second embodiment in which a closing mechanism 36 based on physical weight is provided. and embodiments. In the first embodiment, there is a rotating shaft 37 that allows the lid 35 to be opened and closed, and an opening/closing device 41 that drives the lid 35 with respect to the rotating shaft 37 is provided.

In the case of the second embodiment, a load having a predetermined mass is applied to the opposite side of the lid 35 of the rotating shaft 37 that allows the lid 35 to be opened and closed so as to urge the lid 35 to close. A hanging closure mechanism 36 is attached. FIG. 3(b) shows an enlarged view of the vicinity of the lid 35 in this second embodiment. The opening/closing device 41 in FIG. 3( a ) is changed to the closing mechanism 36 . The load applied by the closing mechanism 36 closes the lid 35 if there is no force applied to the lid 35 from the inside, and the lid 35 is opened by the weight of the sewage P when a predetermined amount of sewage P has accumulated in the temporary tank 32. Adjust so that Here, the predetermined amount can be adjusted to some extent, but it may be appropriately adjusted within the range of the amount of flushing water for one flush of the toilet bowl 12 or the amount obtained by adding the amount of assumed waste. With such proper adjustment, the lid 35 can be automatically closed according to the change in the suction mechanism 33 properly sucking the sewage P from the toilet bowl 12 without providing an electronic control mechanism for the closing mechanism. It can be opened in time. However, the first embodiment using the control device 45 facilitates highly accurate control.

In either embodiment, the top of the pack device 13 has a removable top plate 60 on which the suction device 16 is placed. A hole 68 is provided in the center of the top plate 60 . The outlet 34 of the suction device 16 is inserted into the hole 68 . A storage section 61 under the top plate 60 accommodates a tube set 62 of thermoplastic resin film. The tube set 62 itself is a long cylindrical film that is folded repeatedly in mountain and valley folds to compress the height so that it can be accommodated, and can be expanded into the original cylindrical shape by pulling it in one direction from the center. FIG. 3 shows the folded cross section. In addition, the shape is not limited to such a shape in which mountain folds and valley folds are repeated, and may be a donut shape by winding from the center, or other shapes. Regardless of the shape, it is arranged so that the stored film unwinds toward the inside and downward. A hole 69 is also formed in the center of the bottom surface 63 of the storage section 61 so that the unwound tubular film 64 can be drawn downward. On the other hand, when housing a new tube set 62 in the housing portion 61, the top plate 60 is removed.

Under the bottom surface 63, rollers 71a and 71b are provided as transfer means for applying force to unwind the film 64 and transfer it downward. Although the position does not necessarily have to be the arrangement shown in the figure, it is preferable from a structural point of view to be provided above cutters 73a and 73b, which will be described later. In addition, although rollers 71a and 71b are provided at two locations on the left and right in the drawing as transfer means, the present invention is not limited to this form, and a force capable of transferring the film 64 downward can be applied at the required timing. The structure of the transfer means is not particularly limited as long as it is possible.

Under the rollers 71a and 71b, upper heat welding means 72a and 72b, cutters 73a and 73b, and lower heat welding means 74a and 74b are provided with the film 64 interposed therebetween. It is preferable that a vertical gap of about 2 to 4 cm is secured between the crossing point of the cutters 73a and 73b and the point where the upper and lower thermal welding means face each other, because the work accuracy is stable. The upper heat-welding means 72a, 72b and the lower heat-welding means 74a, 74b have a heating function capable of melting the film 64 made of thermoplastic resin, and a mechanism capable of sealing the film 64 by combining them from the left and right. be. The drawings schematically describe the shape, and the shape is not limited to the described shape as long as it has a function of melting and sealing. Although it depends on the type of thermoplastic resin film, it is preferable to select a film that can be heated and welded at around 100° C. and heat the upper heat welding means 72a, 72b and the lower heat welding means 74a, 74b at a temperature corresponding to that. Heating may be performed only immediately before the film 64 is sealed, and the energy required for heating can be used sufficiently with a battery level.

The cutters 73a and 73b are cutting means that can approach from the left and right sides of the film 64 and cut between the heat-sealed portions (the bottom contact portion 65 and the upper contact portion 67). This is also shown in the drawing as an example and is not limited to such a structure. The film 64 may be completely cut, or may be perforated in the film 64 so that it can be easily cut by hand. For quick cutting, it is more preferable to heat the cutters 73a and 73b to about 120 to 200° C. to melt the film while cutting. In this case, heating is only performed during cutting, and only the tip of the blade needs to be heated.

Below the driving mechanism 70 having these rollers 71a, 71b, upper heat welding means 72a, 72b, cutters 73a, 73b, and lower heat welding means 74a, 74b, dirty water is disposed with the bottom contact portion 65, which is the tip of the film 64, as the bottom. There is a storage part 66 that is a space that can store the part that stores P. After being cut by the cutters 73a and 73b, a pack 79 sealing the sewage P is separated here. Although the figure encloses the whole, an opening/closing device may be provided so that the pack 79 can be taken out after use, or one side may be opened so that it can be taken out. In the drawing, the storage part 66 which stores one pack 79 and is taken out each time it is used is described, but the storage part 66 can be used as a trash can to store a large number of packs 79 so that they can be discarded together later. You can do it.

An example of the procedure for using the toilet unit according to the present invention will be described in order. First, an example of procedures for closing and opening the lid 35 by the closing mechanism 36 will be described with reference to FIG. Note that the illustration of the top plate 60 is omitted in the drawing for ease of viewing. FIG. 4(a) shows the state immediately after the toilet bowl 12 is used. The pump is driven to discharge cleansing water from the nozzle 23 according to an instruction by operating a predetermined switch or button provided on the toilet unit 11 . At this stage, the lid 35 is closed by the opening/closing device 41 . When the suction mechanism 33 of the suction device 16 is driven simultaneously with the start of cleaning by releasing the cleaning water or following the cleaning, the gas in the temporary tank 32 is discharged as the lid 35 is closed. , a suction pressure is generated by which the sewage P in the drain pipe 25 is sucked up. As a result, the sewage P in the toilet bowl 12 is discharged (FIG. 4(b)). As the suction pressure continues, the sewage P in the drain pipe 25 reaches the temporary tank 32 and is temporarily stored (FIG. 4(c)). When the dirty water P is completely sucked (FIG. 4(d)), the drain pipe 25 is not closed, so even if the suction mechanism 33 is in motion, the dirty water P is no longer sucked. When this happens, the suction mechanism 33 may be stopped. The timing at which it is desirable to stop the suction mechanism 33 is the timing when the sewage P in the drain pipe 25 has been completely sucked, so it can be roughly calculated from the internal capacity of the drain pipe 25 and the output of the suction mechanism 33. Therefore, the timer should be controlled by On the other hand, the opening/closing device 41 may be controlled to be opened in synchronization with the timing at which the suction mechanism 33 is stopped. When the opening/closing device 41 opens the lid 35, the sewage P drops into the packing device 13 (FIG. 4(e)). Since the fall is free fall, it is completed in about 5 to 10 seconds. The opening/closing device 41 closes the lid 35 again at the timing when it finishes falling.

In addition, instead of the opening/closing device 40, an embodiment in which a closing device that closes with a load is provided can also be adopted. An example of the procedure for use in that case will be described in order in accordance with the corresponding FIG. At the stage of FIG. 4(a), which is the state immediately after the toilet bowl 12 is used, the lid 35 is closed by the load of the closing mechanism. For example, the position of the opening/closing device 41 shown in FIG. When the suction mechanism 33 of the suction device 16 is driven simultaneously with the start of cleaning by releasing the cleaning water or following the cleaning, the gas in the temporary tank 32 is discharged as the lid 35 is closed. , a suction pressure is generated by which the sewage P in the drain pipe 25 is sucked up. As a result, the sewage P in the toilet bowl 12 is discharged (FIG. 4(b)). As the suction pressure continues, the sewage P in the drain pipe 25 reaches the temporary tank 32 and is temporarily stored (FIG. 4(c)). The load applied to the lid 35 at this point may be reduced by the suction pressure at which the stored sewage P is also sucked, and is not so large as to exceed the load applied to close by the closing mechanism, so the lid 35 is closed. Suction pressure continues. When the sewage P is completely sucked (FIG. 4(d)), the drain pipe 25 is not closed, so even if the suction mechanism 33 is in motion, the sewage P is no longer sucked, and the full load of the sewage P is applied to the lid 35. . When this happens, the suction mechanism 33 may be stopped. The timing at which it is desirable to stop the suction mechanism 33 is the timing when the sewage P in the drain pipe 25 has been completely sucked, so it can be roughly calculated from the internal capacity of the drain pipe 25 and the output of the suction mechanism 33. Therefore, the timer should be controlled by On the other hand, since the load applied by the closing mechanism is adjusted to be smaller than the total load of the sewage P at this stage, the lid 35 cannot be completely closed and is opened. Once opened, due to the force of the dirty water P, the dirty water P falls to some extent into the packing device 13 even with the load of the closing mechanism (FIG. 4(e)). Furthermore, a mechanical mechanism may be provided so that it takes time for the lid 35 to return once it has been opened.

Next, an example of the procedure for packaging by the packing device 13 will be described with reference to FIG. The dirty water P that has fallen from the suction device 16 is dropped onto the part of the film 64 that is opened in the center. This state is shown in FIG. In this state, the rollers 71a and 71b are not rotating, the upper heat welding means 72a and 72b, the cutters 73a and 73b, and the lower heat welding means 74a and 74b are open. It is possible to reach FIG. 5B shows a state in which the dirty water P is dropped into the film 64 inside the storage portion 66 . Basically, the waste water P for one use of the toilet bowl 12 is accumulated in the film 64 in this manner.

This pooled portion is then packaged. The upper heat-sealing means 72a, 72b and the lower heat-sealing means 74a, 74b of the drive mechanism 70 are brought closer together, and the film 64 is sealed above the part where the dirty water P is accumulated. Each of the heat-sealing means has a metal surface that is heated by electricity, and the surfaces are opposed to each other. First, the upper heat-welding means 72a and 72b and the lower heat-welding means 74a and 74b are brought into close contact with each other with the film 64 sandwiched therebetween, and the sandwiched film 64 is heat-welded. The portion sandwiched and heat-sealed between the lower heat-sealing means 74a and 74b is sealed as the upper contact portion 67, thereby sealing the lower portion where the sewage P is accumulated. This state is shown in FIG. 5(c). On the other hand, the portion sandwiched between the upper thermal welding means 72a and 72b and thermally welded becomes the next bottom contact portion 65. As shown in FIG. However, the film 64 has not yet been cut at this stage. The vertical length of each thermally welded portion is preferably 1 cm or more and 5 cm or less. If it is too short, it may not be sufficiently sealed. On the other hand, if it is too long, it will be wasted. Subsequently, the cutters 73a and 73b approach and cross each other to form a bottom contact portion 65 formed by the upper heat welding means 72a and 72b and an upper contact portion 67 formed by the lower heat welding means 74a and 74b. Cut to separate the parts. This state is shown in FIG. 5(d). The length between them, that is, the length between the lower ends of the upper heat welding means 72a and 72b and the upper ends of the lower heat welding means 74a and 74b is preferably 1 cm or more and 4 cm or less. If it is too short, the cutting position tends to come off from this interval. On the other hand, if it is too long, the film 64 will be wasted.

FIG. 5(e) shows a state in which the packs 79 are separated by being cut by the cutters 73a and 73b. The upper end of the pack 79 is an upper sealing portion 67 sealed by lower heat-sealing means 74a, 74b. The lower end of the pack 79 is the bottom contact portion 65 formed at the stage where the same work was performed one time before. The pack 79 is removed from the storage section 66 or put together under the storage section 66 to make room for the next work in the storage section 66 . When space is available, rollers 71a and 71b are rotated so that film 64 is unwound from tube set 62 and lowered. The lower part of the film 64 descends to the storage part 66 and waits for the next sewage P to be dropped. This state is shown in FIG. 5(f).

A third embodiment of the toilet unit according to the present invention, which is different in packaging, will be described with reference to FIG. The initial state is shown in FIG. 6(a). The basic configuration is the same as the embodiment shown in FIGS. 3 to 5, but compared to the embodiment shown in FIG. 3, the thermal welding means 76a and 76b are vertically elongated instead of vertically separated. . The vertical length of the portion to be thermally welded is preferably about 2 cm or more and 10 cm or less. If it is too short, the seal may not be sufficient, and if it is too long, the film 64 will be wasted. Further, the cutters 77a and 77b are provided below the portion (adhesion portion 78) to be thermally welded by the thermal adhesion means 76a and 76b so as to cut the adhesion portion 78 scrolled downward by the transfer means after the thermal adhesion. is distributed to

First, after the sewage P is dropped, the heat-sealing means 76a and 76b approach each other, and the state where the film 64 is sealed above the sewage P is shown in FIG. 6(b). A sealed portion of the film 64 is referred to as a contact portion 78 . Up to this point, the wastewater P for one use of the toilet bowl 12 is packaged in the film 64 . Subsequently, the rollers 71a and 71b are rotated to lower the film 64 so that the contact portion 78 is positioned near the center of the cutting position by the cutters 77a and 77b (FIG. 6(c)). Therefore, when the cutters 77a and 77b are brought closer to cut the vicinity of the center of the close contact portion 78 (FIG. 6(d)), the pack 79 containing the separated sewage P is sealed and left on the bottom, and the bottom is on the top. A film 64 whose lower end is closed to form a contact portion 65 remains (FIG. 6(e)). After removing the pack 79, the rollers 71a and 71b are rotated so as to lower the film 64 to wait for the next wastewater P to be dropped (FIG. 6(f)).

Still another fourth embodiment of the toilet unit according to the present invention, which is different in packaging, will be described with reference to FIG. The initial state is shown in FIG. 7(a). The cutters 77a and 77b are omitted from the embodiment shown in FIG. 6(a). Also, the length of the thermal welding means 76a, 76b may be smaller than in the embodiment of FIG.

First, after the sewage P is dropped (FIG. 7(b)), the thermal welding means 76a and 76b approach each other, and the film 64 is sealed above the sewage P, as shown in FIG. 7(c). shown in A sealed portion of the film 64 is referred to as a contact portion 78 . Up to this point, the wastewater P for one use of the toilet bowl 12 is packaged in the film 64 . Subsequently, the rollers 71a and 71b are rotated to lower the film 64 (FIG. 7(d)). Unlike the embodiment of FIG. 6, since the contact portion 78 is not cut, it is lowered to a point where the next drop of dirty water P can be accepted. This state is shown in FIG. Although the sealed pack 79 remains connected, it can continue to be operated as it is provided that the storage section 66 has a sufficient volume. FIG. 7(f) shows a state in which packaging is repeated in the same manner from this state.

The toilet unit according to the invention preferably has a control device 45 for controlling these mechanisms. FIG. 8 shows a block diagram of a mechanism for controlling the entire toilet unit implementing the embodiment shown in FIG. An example of a flow chart for executing this is shown in FIG. In the initial state, the lid 35 is closed and the suction mechanism 33 is stopped. The thermal welding means 72, 74 and the cutter 73 are not heated (S101). As for the toilet bowl 12 , the control device 45 controls a pump that delivers flush water from the nozzle 23 . When the user who used the toilet bowl 12 (S102) presses the button 42 as an instruction to clean (S103), the pressing operation is transmitted to the control device 45 as an electric signal. The control device 45 receiving this operates the pump (S104, FIG. 4(a)). At the timing when the pump is operated to send out the washing water and the dirty water P is accumulated, the control device 45 operates the suction mechanism 33 to suck the dirty water P into the suction device 16 (S105, FIGS. 4(b) and (c). ). When the sewage P is collectively sucked into the temporary tank 32 (S106, FIG. 4(d)), the controller 45 stops the suction mechanism 33 and issues an instruction to electrically open the lid 35 (S107, FIG. 4). (e)). Alternatively, the lid 35 is automatically opened by the closing mechanism. In any case, the cover 35 is opened, and the dirty water P collectively drops into the film 64 (FIGS. 5(a) and 5(b)). By once sucking the sewage P into the temporary tank 32 and then dropping it, the remaining amount is minimized and the odor is less likely to remain. After dropping, the lid 35 is closed (S108).

Next, the control device 45 causes the upper heat welding means 72a, 72b and the lower heat welding means 74a, 74b to heat and approach each other to perform heat welding (S111, FIG. 5(c)). The heating is about 100° C., depending on the type of film, and since only the portion to be welded needs to be heated, the temperature can be raised quickly. does not need to be heated. Subsequently, the controller 45 crosses the cutters 73a and 73b to cut the film 64 (S112, FIG. 5(d)). Heat welding and cutting should be performed almost at the same time or 2 to 3 seconds after heat welding. In particular, it is preferable to slightly shift the timing from heat welding, because it is easier to cut reliably. When the cutters 73a and 73b are heated for cutting, they do not need to be heated during standby, and may be heated only immediately before cutting. When the cutting is finished, the controller 45 separates the upper heat welding means 72a, 72b, the cutters 73a, 73b, and the lower heat welding means 74a, 74b from each other (S113, FIG. 5(e)). At this stage, the heating has already been completed. Thereafter, the controller 45 operates the rollers 71a and 71b to lower the film 64 (S114, FIG. 5(f)). The length of the film 64 to be lowered should be reduced to such an extent that the content of the pack 79 can be secured by about 2 to 3 liters at the stage of being sealed by the upper contact portion 67 .

In the case of using the embodiment shown in FIG. 6, it is preferable that after thermal welding is performed by the thermal welding means 76a and 76b, scrolling is performed by the rollers 71a and 71b and then cutting is performed by the cutters 77a and 77b. . Other than that, basically the same procedure can be used. Moreover, when using the embodiment shown in FIG. 7, cutting with the cutters 77a and 77b is further omitted.

When the toilet unit according to the present invention is properly controlled and operated by the control device 45, the electric power used for sending flush water from the nozzle 23, opening and closing the suction mechanism 33 and the lid 35, and operating the drive mechanism 70 can be minimized. For example, the power generated by the solar panel and the electricity charged in the battery can be sufficient to operate, and it can be operated even in situations where commercial power cannot be secured. In addition, even in an environment where a commercial power supply can be used, energy-saving operation is possible because the time required for heating and operation is reduced. As a result, even in the event of a disaster or at a nursing care site, it is possible to use a comfortable toilet bowl that can use flush water, and to dispose of the dirty water P generated by using it as a packaged waste, which is hygienic. , it is possible to provide a suitable environment for suppressing odors.
