Description

  The present invention relates to a portable toilet device in which excrement for each excretion is accommodated in a storage unit in a packaged form in which the excretion is performed each time, and more specifically, is stored in the storage unit. The present invention relates to a portable toilet device that can efficiently store a waste package (hereinafter referred to as a pack) in a storage unit.

  Conventionally, a toilet apparatus in which excrement for each excretion is accommodated in a storage portion in a form in which the excrement is stored in a bag-like or tube-like flexible container and the container is hermetically sealed is known from Patent Documents 1-3. Some of them are in practical use.

  However, in the portable toilet device known from Patent Documents 1 to 3 described above, the excrement packs in the form of individual packages are naturally dropped and stored in the lower space of the toilet bowl, but contain a plurality of falling packs. In addition, there was a point to be improved in terms of storage form.

  That is, since the excrement pack sealed in the bag-like container for each excretion only falls into a storage part formed by a container such as a box disposed below the toilet bowl, it is dropped by a natural drop. For example, in order to accommodate and store a plurality of packs of at least about 4 to 6 times in order, a container made of a box or the like serving as a storage portion disposed below the toilet bowl has a relatively large volume space. There is a need.

On the other hand, in order to install such a portable toilet in, for example, a private room of a general household, it is desirable that the overall size of the toilet is not too large, and it becomes a storage unit for packs arranged below the toilet. When the volume of the container is increased, the entire portable toilet becomes bulky, and there is a problem that elderly people with weak legs and users who have handicap on the lower limbs are difficult to sit on the toilet. The same applies to this portable toilet installed in a private room such as a hospital.

  Therefore, in the present invention, in a portable toilet device in which excrement for each dose is sealed and packed in a flexible bag-like container, the bulk of the entire toilet is not made too high, and it is suitable for elderly people and persons with reduced mobility. Very easy to sit down on the toilet seat, while orderly storing a plurality of packs of excrement that can be stored under the toilet bowl, the number of packs that can be stored is at least about 4-6 times It is an object of the present invention to provide a portable toilet that can be accommodated.

  The configuration of the excrement disposal apparatus of the present invention made for the purpose of solving the above-described problem is that, for each excretion, a pack in which the excrement is accommodated and sealed in a flexible bag is placed below the toilet body. In a portable toilet device that is formed so as to be dropped and stored in the storage unit, the pack that has been dropped is moved within the storage unit to a pack storage unit that forms a shallow box located almost immediately below the sealed pack that is falling. The moving means is provided.

  In the toilet device of the present invention described above, as the pack moving means, a conveyor using a ball or a roller as a rolling medium, or a scraper-like or wiper-like sweeping lever can be selected. The pack can be moved by rotation (oscillation) or parallel movement.

  Further, in the toilet apparatus of the present invention, the height of the sealing position or sealing cut position of the pack that contains and seals the excrement is approximately 1 / of the length of the pack as viewed from the bottom surface of the container serving as the storage section. 2 or more, preferably by disposing at a height approximately equal to about 2/3, a pack that accommodates excrement for each excretion and is sealed and falls into the reservoir is diffused into the reservoir. Therefore, it is not necessary to provide a pack moving means in the reservoir.

  In the present invention, packs that are at least about 6 excretions in packs in which the excrement is accommodated in a bag body and sealed every excretion do not stack the packs that fall in the storage unit. The height of the toilet device can be kept within the required height and the height of the toilet seat can be set low. On the other hand, packs for multiple excretion can be stored efficiently in the pack reservoir. Therefore, the number of collected packs collected can be reduced.

Next, an example of the excrement disposal apparatus of the present invention will be described with reference to the drawings.
FIG. 1 is a cross-sectional perspective view of the portable toilet device to which the present invention is applied (hereinafter also referred to as “portable toilet” in the present specification) with the right half omitted, and FIG. 2 is a cross-sectional view of the toilet of FIG. 1 to which the present invention is applied. 3 is a schematic sectional side view of a pack storage section provided with a guide conveyor as a pipe moving means, FIG. 4 is a schematic plan view of a pack storage section provided with a cleaning means as a pack moving means, and FIG. It is sectional drawing of the pack which accommodated and sealed the thing.

  The portable toilet PT to which the present invention is applied is a toilet body 1 formed in a hollow box shape having a height from the floor surface of about 350 to 500 mm, preferably about 350 to 450 mm, and a width and depth of about 450 to 500 mm. On the upper surface 1a, a Western-style toilet-shaped hole 2 is drilled, and a substantially O-shaped or U-shaped toilet seat 3 is disposed in the hole 2 as viewed from above, and a hinge is attached to the back end of the toilet seat 3 here. A two-fold type lid 4 is provided so as to be freely opened and closed. Some lids 4 are not folded in two.

  An intermediate floor 5 in which a hole 6 for dropping excrement having a diameter smaller than that of the hole 2 (here, about 120 to 150 mmφ) is formed in the central portion at a position closer to the upper side than the intermediate portion in the height direction inside the main body 1. The excrement package mechanism Pa, which will be described later, is installed on the lower surface side of the intermediate floor 5 (below the drop hole 6).

  Inside the main body 1, between the upper surface 1a and the intermediate floor 5, a guide member 7 having a tapered or funnel-shaped cross section is provided between the hole 2 and the dropping hole 6 on the upper surface 1a. The illustrated guide member 7 includes an annular support member 7 a larger than the hole of the toilet seat 3, a support surface that is supported by the upper end coupled to the support member 7 a, and a lower end that is supported outside the hole 6 of the intermediate floor 5. It is formed from the member 7b, and supports the form of the bag 8 described later and guides the fall of excrement.

  On the intermediate floor 5 located outside the guide surface member 7b of the guide member 7, for example, a flexible synthetic resin film bag made of polyethylene, for example, is folded into a bellows as an example. An elongated bag body 8 (for example, about 20 to 30 m) is disposed so as to surround the entire guide member 7 as a bag body 8 for packing excrement (see FIG. 2). 8, the tip side facing upward is turned downward by the annular support member 7 a in the guide member 7, and supported by the upper surface of the guide surface member 7 b having a cross-section funnel shape, so that the falling hole of the intermediate floor 5 is supported. 6 is drawn to the lower surface side of the intermediate floor 5. Therefore, the bag body 8 also includes a portion supported by the guide surface member 7b, and a lower portion of the portion is a waste receiving portion 8a.

Next, the package mechanism Pa disposed below the dropping hole 6 will be described.
This package mechanism Pa has two sets of feed rolls 10 (on the left and right outer sides of the dropping hole 6 in order to hold both ends in the width direction of the bag body 8 drawn downward through the dropping hole 6. A shallow box-like casing having an open upper surface provided with a shutter portion serving as an openable bottom, which will be described later, on the lower surface, and a drop hole 6. Immediately below, in this example, two shutter parts 11, 12 that are opened and closed by sliding back and forth, a pair of operating arms 13, 14 that slidably support the shutter parts 11, 12, and the shutter part The heat seal cutter 15 provided at the butting ends of 11 and 12 is formed. The two sets of feed rolls 10 and the operating arms 12 and 13 in this example are driven by separate motors (not shown). For example, a foot-operated lever provided pivotally on the main body 1 is provided. A drive mechanism that converts the up and down swing stroke into a rotational motion of a roll or a sliding motion of an arm may be used.

  Here, in the illustrated example, the heat seal cutter 15 provided at the abutting ends of the shutter portions 11 and 12 is divided into two sets, an upper portion and a lower portion, at an upper portion and a lower portion in the thickness direction of the shutter portions 11 and 12. Heaters 15a and 15b are provided, and by these two heaters 15a and 15b, the two parts corresponding to the heaters 15a and 15b of the bag body 8 sent out downward by the roll 10 are arranged in a horizontal line shape at two points close to each other. And the middle of the two sealing parts is cut by the lower heater 15b. 8b and 8c are heat-sealed portions.

  In this way, the bag body that has been cut and separated from the bag body 8 (hereinafter, the bag body immediately before being cut is referred to as a pack 8) is formed into a single pack 8A that is cut and independent as illustrated in FIG. Naturally falls downward. In FIG. 5, Z is a packed excrement. In the remaining bag body 8 (portion that becomes the pack 8A), the portion 8b linearly sealed by the upper heater 15a becomes the bottom (hereinafter also referred to as the bottom 8b) of each pack 8A in the continuous bag body. The length of the bag 8 delivered by the roll 10 is the length of the portion supported by the guide member 7 (about 200 to 300 mm).

  Although not shown, the heaters 15a and 15b are provided in parallel above and below the opposing surfaces of the shutter portions 11 and 12, and a third heater (not shown) that acts as a cutter is provided between the heaters 15a and 15b. It may be configured.

  As described above, the excrement Z is sealed each time to make the pack 8A, and the portion of the pack 8 that is newly supported by the guide member 7 and is closed inside the toilet bowl by the heat seal portion 8b The package mechanism Pa is formed as a receiving container for the next excretion to be excreted while sitting on 3.

  In the toilet apparatus of the present invention, a sensor (not shown) such as a pressure-sensitive sensor, an optical sensor, or an infrared sensor is provided in the toilet seat 3 or the vicinity thereof, and a motor control circuit ( (Not shown) is switched on and enters the standby state. When the passenger leaves the toilet seat, the motor is activated to rotate the roll 10 and feed the bag body 8 by a predetermined amount, and the heat seal cutter 15 (15a, 15b) Although it is desirable to operate, these operations may be performed by manual operation such as a switch of a user or an assistant.

  Further, in order to detect that foreign matter or the like is caught between the heaters 15a and 15b of the shutter portions 11 and 12, a micro switch (not shown) is provided in the vicinity of the heaters 15a and 15b. There is also a configuration in which the shutters 11 and 12 are opened again by recognizing that it is “ant” and the pack 8 is sent again, and the pack 8 is heat-sealed and cut again.

  In this type of toilet apparatus, a box-shaped extraction 16 is provided as a storage part for excrement packed in a lower space of the package mechanism Pa in the toilet body 1 so as to be freely inserted into and removed from the body 1. In the present invention, this extraction 16 is provided with a mechanism schematically shown in FIGS. 3 and 4, and this point will be described next.

  In FIG. 3, a guide slope 17 by a ball conveyor having a cone shape, a mountain shape, or an inclined surface shape is provided at the center of the extracted 16 so that the falling pack 8A is extracted and slid down around the inside of the 16. It is a thing.

  FIG. 4 shows the extraction 16 provided with either a rocking scraper 18 or a translation-type scraper 19, and extracted and dropped to the approximate center of the pack 8A. The example which made it move to is shown typically. In this case, it is optional to use either human power or power such as a motor or a cylinder as the driving force of the scraper 18 or 19.

  In the present invention, regardless of the guide slope 17 and the scrapers 18 and 19 by the ball conveyor provided in the extractor 16 that is a storage part of the pack 8A, the space between the bottom surface 16a of the extract 16 and the heater 15b in the package mechanism Pa The distance h is formed so as to ensure at least 1/2, preferably 2/3 or more of the length L (or height in this embodiment, about 200 to 300 mm) of the pack 8A (with the above specific numerical values) The pack 8A that is cut and extracted by the heater 15b and falls to 16 by being at least 100 to 150 mm, preferably about 133 to 200 mm) is extracted, and the packs 8A are stacked on the bottom surface of the 16 It can be dropped and stored.

  The above-mentioned regulation of the distance h is based on the numerical value obtained by the inventor of the present invention by actually repeating the test, and why the packs 8A are stacked on each other when the distance h is set as described above. It has not been clarified at this time whether it can be extracted and successfully arranged on the bottom of 16.

  An example of the portable toilet device of the present invention configured as described above is used in the following manner. When the stool person sits on the toilet seat 3, the pressure-sensitive switch detects it and the motors of the roll 10 and the arms 13, 14 are in a standby state. At this time, the bottom 8b of the bag 8 that becomes the pack 8A is heat-sealed and sealed, and the shutter portions 11 and 12 are also closed. In this state, when the excrement is accommodated near the bottom 8b of the accommodating part 8a in the pack 8 and one excretion ends, and when the occupant stands from the toilet seat 3, each motor is activated by the action of the pressure sensitive switch. Then, the closed shutter portions 11 and 12 are opened in the direction away from each other by the action of the operating arms 13 and 14, and the feed roll 10 is rotated in the direction of the arrow by the motor to feed the pack 8 downward. This delivery amount is about 200 to 300 mm as described above, but it becomes a specific value in the range of 200 to 300 mm by setting the delivery amount for each toilet device.

  When the pack 8 is fed downward by a predetermined amount by the roll 10, the arm motor rotates in reverse to operate the shutter parts 11, 12, which have been separated from the operating arms 13, 14, to heat the bag body 8. The part (mouth) facing the seal cutter 15 is welded by the action of the two heaters 15a and 15b, and the bag body 8 is cut at the middle part of the two welding lines by the action of the lower heater 15b. Then, a new bottom 8b is formed by the action of the upper heater 15a. In this state, the heaters 15a and 15b are deactivated, the shutter portions 11 and 12 are held closed, and the bottom of the sealed pack 8 is supported from below to enter a standby state for the next excretion. Since the above operation is repeated for each excretion, the number of operations of the feed motor of the pack 8 or the number of rotations of the roll 10 is counted, and the current consumption (or remaining amount) of the pack 8 is calculated. For example, when the remaining amount reaches 30 times, it is advisable to take measures such as displaying a sign for refilling the bag with a lamp or the like, and sounding an alarm when the remaining amount is less than 10 times.

  On the other hand, the pack 8A that has been cut into a lump by the mouth being cut by the heater 15b in the state where the excrement is accommodated is extracted and falls to the center of the 16 but the extract 16 is provided with a guide slope 17 And extracted in the following manner and stored in 16. That is, the falling pack 8A falls on the guide slope 17, but this slope 17 is extracted and extends around the 16 so that the bulk pack 8A is guided by the slope 17 and extracted around the 16 Will be sent. Thereafter, the pack 8A that falls in the above-described manner for each excretion is extracted from the storage unit and stored in the interior 16. When a predetermined number of packs 8A are stored in the extracted 16, the extracted 16 is pulled out from the main body 1 and each pack 8A is collected.

  When the scraper-like scraping means 18 or 19 is provided in the extraction 16, the pack 8A that is extracted and falls to the substantially central portion of the 16 is extracted by the reciprocating operation of the scraping means 18 or 19 and left of the 16 Alternatively, the packs 8A are stored on the right side of the extraction 16 without being stacked.

  On the other hand, in the toilet apparatus of the present invention, when the distance h between the heat seal position by the heaters 15a, 15b of the pack 8 or the cut position and the bottom surface 16a of the extracted 16 is within the range of about 133 to 200 mm, The pack 8A having a length L of about 200 to 300 mm is cut and laid down on the bottom surface 16a of the 16 by the action of the distance h when the first pack 8A is extracted and falls to the center of the 16 It becomes a posture of a state and is left still on this bottom surface 16a.

  Here, when the excrement Z enters and the upper end of the pack 8 is heat-sealed by the heater 15b, the pack 8 contains air in addition to the excrement Z. It looks like a balloon with loose air or a little air. Therefore, if the pack 8A falls on the bottom surface 16a of the extracted 16, the balloon-like pack 8A will lie sideways.

  When the next pack 8A falls there, this pack 8A is obstructed by the outer shape of the previous pack 8A that is laid down and left still, or by the action of the shape of the previous pack 8A, the previous pack 8A It lays down on the side of and is left standing. In this way, the packs 8A that fall one after another do not interfere with each other by lying down on the side of each pack 8A that has fallen first, due to the action of the pack 8A that has previously been laid down on the bottom surface 16a and placed in a posture. That is, in a state where they are not stacked, they are extracted and stored in a deployed state diffused on the bottom surface 16a of 16. When the required amount of packs 8A has been accumulated, extraction 16 is extracted from the main body 1 and the packs 8A are collected as in the previous example.

  As described above, in the portable toilet device of the present invention, the excrement is hermetically packaged by the pack 8 for each excretion, extracted as a storage container, and dropped into the 16; Since the packs 8A are not stacked with each other because they are moved around, the 16 storage spaces can be extracted and used effectively, while the vertical space of the lower space of the toilet body 1 is kept small. Therefore, the height of the toilet seat 3 can be set to an easy-to-use height. Therefore, it is possible to provide a portable toilet that is easy to use for an elderly person or a person who does not have freedom of lower limbs.

  Further, since the excrement pack 8A is extracted and stored in the storage portion 16 in a space-efficient manner, it is not necessary to frequently extract the extraction pack 16 containing the pack 8A from the lower portion of the toilet body 1. Incidentally, in this type of conventional toilet device, the packs 8A often overlap each other, and frequently become unusable unless the pack 8A is collected after a few excretions.

  As described above, the toilet device of the present invention collects the pack 8A in which the required number is stored in the extraction container 16 that is the storage container, so it is not only hygienic but also efficient and the handling of excreta is extremely hygienic. Can be carried out easily and conveniently.
