Description

  The present invention relates to a sanitary product processing apparatus capable of crushing sanitary products and discharging them to the sewage drain pipe side. Specifically, a sanitary article can be efficiently pulverized by using a rotary blade member provided with a large number of rotary blades as a means for pulverizing the sanitary article and driving them while engaging with each other.

  If sanitary products such as sanitary products are dumped directly in flush toilets after use, drainage pipes and the like may be clogged. For this reason, sanitary goods are usually thrown into a dedicated trash can installed in the toilet after use, or placed in a plastic bag or the like and stored until the date of garbage collection, and discarded as burning trash.

  In order to eliminate such annoyance, sanitary goods processing equipment is provided in the toilet, etc., and sanitary goods after use are dumped here and pulverized to the extent that they can be discharged into the drainpipe. It is preferable if it can be disposed on the drain pipe side in the same way as the discharged filth. Such a processing apparatus has already been proposed (for example, Patent Document 1).

  Recently, baby diapers and adult nursing diapers have become widespread, but it is very convenient if these diapers can be processed using the same processing device as sanitary goods.

Japanese Patent Laid-Open No. 10-140638

  By the way, the processing apparatus disclosed in Patent Document 1 has a configuration in which a turbine is rotated by tap water pressure, and a pulverization cutter is attached to a rotating shaft attached to the upper part of the turbine. Since the pulverization cutter is mounted at a position sufficiently submerged from the surface of the water, it takes time for the supplied sanitary goods to reach the pulverization cutter, and the rotating cutter is attached to the upper side of the turbine, so it rotates on the turbine. If tap water is supplied to apply force, sanitary articles that have been sunk in the corners may rise again due to the rotating water flow caused by the turbine, and the sanitary articles may not be sufficiently finely pulverized by the rotating cutter. Even if it can be finely pulverized, there is a problem that it takes time to pulverize. In particular, since adult diapers vary in size, there are cases where they may or may not be sufficiently crushed.

  Therefore, the present invention solves such a conventional problem, and in particular, sanitary articles including paper diapers and the like are reliably pulverized by using a pulverizing means having a structure in which two rotary blades are engaged with each other. A sanitary article processing device that can be used is proposed.

In order to solve the above-described problem, the sanitary product processing device according to the present invention described in claim 1 is configured such that the upper end side is opened to serve as a sanitary product input port, and the lower end side serves as a discharge port connected to a drain pipe. Processing enclosures,
It is composed of pulverizing means equipped inside the processing casing,
The crushing means has first and second rotary blade members that mesh with each other,
The crushing means has first and second rotary blade members that mesh with each other,
Each of the first and second rotary blade members is installed horizontally with respect to the insertion port, and the rotary blade members are a plurality of rotary blades provided coaxially with a predetermined interval. It is characterized by comprising.

  In this invention, it has the processing housing | casing which makes | forms a substantially rectangular body shape by which the upper end side was opened and used as the insertion port, and the lower end side was used as the discharge port. A crushing means is provided inside the processing casing. The crushing means has first and second rotary blade members that mesh with each other.

Each of the 1st and 2nd rotary blade member is installed so that it may become horizontal with respect to a slot. These rotary blade members are composed of a plurality of rotary blades provided coaxially with a predetermined interval. The inlet is provided with a lid, and is used in a closed state.
Sanitary goods are thrown in from the inlet of the processing housing. As sanitary goods, in addition to the above-mentioned sanitary goods, baby paper diapers, adult paper diapers and the like that should be crushed and discharged are included.

  The dropped sanitary product is scraped between the first rotary blade member and the second rotary blade member, so that the sanitary product is crushed while being cut by a plurality of rotary blades. When a cross-cut blade is used as the rotary blade, it is pulverized in a state of being finely cut by the rotary blade.

  The crushed sanitary article falls to the lower side of the rotary blade member. Therefore, by flowing an appropriate amount of cleaning water from the inlet side during or after the pulverization process, the pulverized sanitary goods are discharged from the discharge port to the drain pipe (sewage pipe) side together with the cleaning water.

  When the sanitary article scraping means is disposed above the first and second rotary blade members, the sanitary article is forcibly scraped and fed into the rotary blade member side by the scraping means, A part of the sanitary article is roughly cut by the scraping means, so that the sanitary article can be reliably crushed.

  If a means for scraping off the pulverized material is provided between the rotary blades, the pulverized material sandwiched between the rotary blades and the rotary blade can be scraped off. There is no risk of decline.

  In the present invention, sanitary goods are pulverized using a pulverizing means using a rotary blade and discharged.

  According to this, since the sanitary goods are forcibly cut and pulverized by the plurality of rotary blades, the sanitary goods can be pulverized more reliably. Therefore, it is possible to prevent an accident that the drain pipe is clogged.

  Next, a preferred embodiment of the sanitary article processing apparatus according to the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows the relationship when the sanitary article processing apparatus 40 according to the present invention is installed in an existing toilet apparatus (flush toilet) 10.

  In the case of a Western-style toilet, the flush toilet 10 has a toilet 12. A toilet lid 14 is attached to the insertion port side of the toilet 12. There is a flush tank 16 in the back of the toilet 12. A water pipe 24 is connected to the flush tank 16 via a stop cock 18. The discharge part 20 of the toilet 12 is connected to a drain pipe (sewage pipe) 22.

  A sanitary product processing apparatus 40 is installed in the toilet room 11 at a position adjacent to the toilet bowl 12. The sanitary goods processing device 40 is installed on the mounting base 50 after adjusting the height so that the sanitary goods can be easily introduced.

  The sanitary product processing apparatus 40 has a processing housing 60. The discharge port 60 b provided on the lower end side of the processing housing 60 is connected to the conduit 54 via the S-shaped trap tube 52, and the conduit 54 is connected to the drain pipe 22 via the connecting portion 56.

  An end surface (upper end surface) on the upper end side of the processing housing 60 is a charging port 60a that is opened in a rectangular shape. A water supply pipe 26 is led to the vicinity of the inlet. The water supply pipe 26 is for supplying cleaning water into the processing housing 60. In this example, a solenoid valve is used as the stop cock 28 provided in the water supply pipe 26.

  The processing housing 60 has a lid 65. The charging port 60a is closed by the lid 65. The lid 65 is provided with a locking means 66.

  The processing housing 60 includes pulverizing means 70. The crushing means 70 includes a rotary blade. The lid 65 is opened, and sanitary goods to be disposed of from the inlet 60 a side are put into the processing housing 60, and the supplied sanitary goods are finely crushed by the crushing means 70. The ground sanitary goods are discharged together with the washing water.

  A specific example of the crushing means 70 is shown in FIG. FIG. 2 is a longitudinal sectional view of the sanitary article processing apparatus 40, and FIG. 5 is a plan view from the inlet 60a side. The processing housing 60 has a rectangular inlet 60a, which narrows toward the lower end, and has a lower outlet 60b.

  The crushing means 70 is provided inside the processing housing 60 and in the vicinity of the center thereof. The crushing means 70 includes first and second rotary blade members 70A and 70B arranged in meshing relation with each other, and is passed to the left and right side walls 61a and 61b (see FIG. 5) of the processing housing 60. It is fixed with. Accordingly, the first and second rotary blade members 70A and 70B are arranged parallel (horizontal) to the insertion port 60a.

  As shown in FIG. 3, in the first rotary blade member 70A, a plurality of rotary blades 74 (74a, 74b...) Are arranged on the rotary shaft 70a while maintaining a predetermined interval. The second rotary blade member 70B is similarly configured, and is configured by arranging the same or one more rotary blades 76 (76a, 76b,...) On the rotary shaft 70b. Are arranged in a staggered manner. The size of the rotary blades 74 and 76, the number to be installed, and the like vary depending on the accommodation space of the processing housing 60. When the processing casing 60 having a rectangular shape as shown in FIG. 5 and having a narrowed outlet 60b side is used, each of the rotary blade members 70A and 70B is formed using 4 to 7 rotary blades. Is configured.

  Here, the rotary blades 74 and 76 adjacent to each other are not arranged in a state where they are completely meshed with each other. Since sanitary goods to be handled have a certain thickness, in order to make it easy to cut the sanitary goods, in consideration of these thicknesses, as shown in FIG. 2, the interval between adjacent rotary blades 74 and 76, The facing distance to the rotating shafts 70a and 70b is set.

  As the rotary blades 74 and 76, a disk-like rotary blade having a blade-like tip, or an elliptical rotary blade having a sharp tip on its peripheral surface (so-called cross-cut blade) can be used. . The latter rotary blade can be cut into strips more finely than the former rotary blade.

  FIG. 4 shows an example of the latter rotary blade 74, which has a pair of pointed blades 75a at positions facing each other by approximately 180 °. The pointed blade 75a has a blade shape such that the end surfaces of the pointed blades face each other in the rotational direction a. The other rotary blade 76 also has a pointed blade 77a having the same structure (see FIG. 3).

  As shown in FIG. 3, when a plurality of rotary blades 74 are attached to the rotary shaft 70a, the attachment positions of the pointed blades 75a are attached and fixed so that their rotational phases are sequentially shifted by a predetermined angle (about 30 °). Even the other rotary blade 76 is attached and fixed to the rotary shaft 70b in a state where the rotational phase is sequentially shifted by a predetermined angle. Therefore, as shown in FIG. 2, the tip blades 75a and 77a are rotationally driven while maintaining a small gap while facing each other. Actually, the rotary blades 74 and 76 are not driven while being engaged with each other, but when the sanitary product is interposed, the rotary blades 74 and 76 are engaged with each other and the sanitary product is cut.

  In this example, as shown in FIG. 2, the scraping means 80 is disposed above the grinding means 70. The scraping unit 80 is inserted from the input port 60a side so that the sanitary article is surely guided to the center of the crushing unit 70. Therefore, the scraping means 80 is also composed of first and second scraping rotating members 80A and 80B.

  As shown in FIG. 5, the first scraping rotary member 80A is composed of a plurality of rotary bodies 84 (84a, 84b,...). As shown in FIG. 2, a plurality of, for example, four scraping claws 85 a having a bow shape are integrally formed on the circumferential surface of the rotating body 84, and these rotating bodies 84 maintain a predetermined interval. A plurality of rotating shafts 82a are attached and fixed.

  The second scraping rotation member 80B is similarly configured, and a rotating body 86 having a plurality of scraping claws 87a is attached and fixed to a plurality of rotating shafts 82b while maintaining a predetermined interval. In this case, the sanitary article dropped as shown in FIG. 2 can be dropped into the crushing means 70 side, specifically, into the facing gap between the first rotary blade member 70A and the second rotary blade member 70B. The arrangement position of the raking claws 85a and 87a and the raking direction of the raking claws 85a and 87a are selected.

The predetermined interval described above is coarser than in the case of the pulverizing means 70. The facing distance between the first and second scraping rotary members 80A and 80B is also coarser than that of the crushing means 70. This is because none of them is a member whose primary purpose is to impart a grinding function. In order to add a cutting function to the scraping means 80, the rotary grinding means 70 and the scraping means 80, which are the same as the grinding means 70, are detachably mounted and fixed to the processing housing 60. This will be described with reference to FIG. FIG. 5 shows a specific example of the scraping means 80.

  As shown in FIG. 5, in order to pivotally support one end side of the rotary shaft 82a provided in the first scraping rotary member 80A, a mounting fixing means 90 that is mounted and fixed in a mounting hole 62a formed in the side wall 61a. Consists of a bearing 90a and a fixing portion 90b that fixes the bearing 90a and is attached to the side wall 61a.

  The fixing part 90b is made of a material that can be watertightly attached to the side wall 61a. In this example, it is formed of a relatively hard rubber material or plastic material, and this fixing portion 90b is fixed by being fitted into the side wall 61a.

  The other end of the rotating shaft 82a is also supported by the mounting and fixing means 92. The mounting fixing means 92 is mounted and fixed in a relatively large mounting hole 62b formed in the side wall 61b. The mounting and fixing means 92 has the same configuration as described above, and includes a bearing 92a attached to the inner surface thereof and a fixing portion 92b for fixing the bearing 92a.

  The second scraping rotary member 80B is configured in the same manner. That is, the mounting / fixing means 94 is provided to support one end of the rotating shaft 82b, and the mounting / fixing means 96 is provided to support the other end. The mounting / fixing means 94 includes a bearing 94a and a fixing portion 94b, and the other mounting / fixing means 96 includes a bearing 96a and a fixing portion 96b. One mounting fixing means 94 is mounted and fixed in a mounting hole 63a provided in the side wall 61a, and the other mounting fixing means 96 is mounted and fixed in a relatively large mounting hole 63b provided in the side wall 61b.

  Driving means 100 for driving the rotating shafts 82a and 82b is provided outside the side wall 61b. Therefore, gears 97a and 97b that mesh with each other are attached to the respective rotary shafts 82a and 82b, and in this example, the rotational force from the drive motor 103 is transmitted through the pulley 101 attached to one rotary shaft 82a side. Is done. Therefore, the pulley 102 on the drive motor 103 side and the pulley 101 on the rotating shaft 82 a side are connected by the belt 104.

  Further, since the rotational force from the drive motor 103 side is also transmitted to the grinding means 70 side, a rotational force transmission system as shown in FIG. 6 is configured. For this reason, a pair of gears 98a and 98b meshing with each other in relation to the rotation shafts 70a and 70b provided in the crushing means 70 are provided. Thus, the rotational force is transmitted to the gear 98a side.

  The driving means 100 and gears 97a and 97b attached to the outer surface of the processing housing 60 are covered by a rectangular case 110 so as not to be exposed to the outside.

  As described above, the lid 65 is provided on the insertion port 60 a side of the processing housing 60, and the lid 65 is provided with a lock unit 66. Therefore, as shown in FIGS. 7 and 8, a locking claw 66a is provided at the tip of the lid body 65, and a locking projection 66b is also provided on the insertion port 60a side corresponding to the locking claw 66a. ing. The locking means 66 is configured by engaging the locking claw 66a with the locking projection 66b, and the lid 65 can be locked by using the locking means 66.

  As shown in FIG. 2, a scraping member 120 is provided below the rotary blade members 70 </ b> A and 70 </ b> B in association with the crushing means 70. The scraping member 120 is provided to scrape crushed sanitary goods entangled between the rotary blade 74 and the rotary blade 74 (rotary blades 76 and 76).

  An example is shown in FIG. The scraping member 120 shown in FIG. 9 includes a comb-like plate body 122 as shown in FIGS. 9A and 9B, and the comb teeth 124 so that the comb teeth 124 can enter between the adjacent rotary blades 74 described above. 124 pitches, depths and numbers are selected. The plate body 122 is bent at a predetermined angle so as to face the rotation direction of the rotary blade (see FIG. 9B).

  As the scraping member 120, a rotating brush may be used instead of the plate as shown in FIG. In this case, as shown in FIG. 10, a plurality of brush pieces 126a extending radially on one rotating plate 126 are arranged in a coaxial manner, and the rotating blades 74 adjacent to each rotating plate 126 are arranged. What is necessary is just to attach to the inner wall of the process housing | casing 60 shown in FIG. The rotary brush is preferably configured to rotate by itself.

  As shown in FIG. 2, a funnel-shaped partition wall 128 is provided on the input port 60 a side of the processing housing 60, and the tube port 26 a of the water supply pipe 26 is led out to the inside of the partition wall 128. Even when the inserted sanitary goods are not charged to the scraping means 80 side, they can be called to the scraping means 80 side by the action of the partition plate 128. Further, water can be supplied toward the central portions of the scraping means 80 and the pulverizing means 70 by the action of the partition plate 128. As a result, the supplied tap water can be efficiently led to the scraping means 80 side.

  FIG. 11 shows an example of a control system 130 for driving the sanitary product processing apparatus 40. In this example, the control unit 131 includes a CPU. The control unit 131 controls each of the power switch 132 and the crushing switch 133 (see FIG. 2) provided on the processing housing 60 on the input port 60a side. A signal is supplied. The power switch 132 functions as a power switch for the control unit 131 and also functions as a power switch for the water supply electromagnetic valve 28 and the crushing drive motor 103.

  Both the power switch 132 and the crushing switch 133 are provided in the upper part of the cover 110 in this example (see FIG. 2). In this example, the electromagnetic valve 28 and the drive motor 103 described above are controlled at a predetermined timing based on a control signal from the control unit 131.

  FIG. 12 shows an example of the timing chart. FIG. 12 shows a timing chart after the power switch 132 is turned on. After the sanitary goods are put into the processing housing 60, the crushing switch 133 is operated after the lid 65 is closed (FIG. 12A). When the crushing switch 133 is turned on, the drive motor 103 is driven, so that the rotational force is transmitted to the scraping means 80 and the crushing means 70 via the transmission system shown in FIG. As a result, the scraping means 80 and the crushing means 70 are driven to rotate (FIG. 12B).

  When the scraping means 80 is driven, the sanitary articles are scraped by the claws 85a and 87a so that the inserted sanitary articles gather at the center side of the scraping means 80. The sanitary article dropped to the lower side of the scraping means 80 by being scraped reaches the grinding means 70. Since the pulverizing means 70 is composed of a large number of rotary blades, the sanitary product is bitten between the rotary blades 74 and 76 so that the sanitary product is formed into a strip shape by the action of the meshing rotary blades 74 and 76. Cut. Since the rotary blade is a cross-cut blade, sanitary articles cut into strips are further cut into fine pieces and pulverized.

  The electromagnetic valve 28 for water supply operates for a predetermined time before the pulverization processing time T1 elapses, in this example, a predetermined time ΔT1 after the start of the pulverization processing (FIG. 12C). Since the pulverized water guided to the water guide plate 128 by the operation of the electromagnetic valve 28 concentrates in the central portion of the processing housing 60, the pulverized sanitary goods fall to the outlet 60b side while containing moisture. As shown in FIG. 2, the inner diameter of the discharge port 60b is narrower than that of the input port 60a. Therefore, by adjusting the amount of water supplied, the crushed sanitary goods flow down completely from the discharge port 60b to the drain pipe side. Before, since the discharge port 60b is closed, the pulverized water is somewhat accumulated on the discharge port 60b side. The sanitary article is softened somewhat by the accumulated water, so that the pulverized sanitary article can be discharged smoothly.

  In addition to the purpose of facilitating softening of the sanitary goods, the water supply also has the purpose of cleaning the inside of the processing housing 60, so that a sufficient time has passed for the cleaning process after the pulverization process is completed as shown in FIG. 12C. After that, power supply to the electromagnetic valve 28 is controlled to stop. Considering baby goods to adult goods, the size of sanitary goods varies, and therefore, the pulverization time T1 and the water supply time T2 are selected relatively long. In this example, both the predetermined times T1 and T2 are set to about 10 to 20 seconds. These times T1 and T2 can also be configured to be adjustable from the outside. For example, it is possible to switch to three stages such as “short, medium, long” by an adjustment button provided outside. The water supply timing can also be started from the time when the pulverization process is completed as shown in FIG. 12D.

  A second embodiment will be described below with reference to FIG. In the first embodiment, the scraping means 80 is installed on the upper side of the pulverizing means 70 so that sanitary articles dropped from the inlet 60a side can be efficiently dropped to the pulverizing means 70 side.

  In FIG. 13, the scraping means 80 is omitted. Instead of omitting the scraping means 80, the partition plate 128 configured in a funnel shape is opened from the constricted portion in a square shape so that the opening end face 128a surrounds the upper side of the crushing means 70 as shown in the figure. The opening surface.

  By doing so, even when the dropping position of the sanitary goods dropped from the loading port 60a side is bad, for example, when sanitary goods are dropped between the crushing means 70 and the inner surface of the processing housing 60, This prevents the sanitary goods from getting caught in the gap and making it impossible to grind.

  FIG. 14 is a side view of another example of the sanitary product processing apparatus. As in the case of FIG. 6, gears 98a and 98b meshing with each other are attached to the respective rotating shafts 70a and 70b, and one rotation is performed. A pulley 105 is provided on the shaft 70a. Since the pulley 102 is also connected to the drive motor 103, if the belt 104 is connected between the pulleys 102 and 105, the rotational force of the drive motor 103 is transmitted to the crushing means 70, and the rotary blades 74 and 76 are respectively connected. Can be rotated.

  Even when configured in this manner, a pulverization process substantially similar to that of the first embodiment can be realized. In the case of the second embodiment, it can be regarded as a simple sanitary product processing apparatus. Since other configurations are the same as those of the first embodiment, detailed description thereof is omitted.

  The present invention can be applied not only to home use but also to toilet devices installed in hotels, various hospitals, elderly care facilities and the like.
