JP5120902B2 - Odor prevention device for gypsum trap - Google Patents

Description

  The present invention relates to a foul odor prevention tool for a gypsum trap used in a dental clinic, a dental laboratory, or the like.

  Conventionally, in denture clinics, dental laboratories, and the like, various denture working models have been created with plaster. In the course of the work, part of the gypsum is washed away into the sink (a sink tank) by tap water. If the water containing the washed gypsum is discharged to the downstream pipe as it is, the gypsum component (gypsum waste) settles, separates and accumulates in the downstream pipe, and the downstream pipe is clogged.

  For this reason, conventionally, a gypsum trap is installed in the downstream pipe of the sink, and the water that has flowed into the sink is once stored in the gypsum trap, and the gypsum component in the water is settled and separated in the gypsum trap.

  On the other hand, when the gypsum trap is continuously used, a strong odor such as hydrogen sulfide is generated inside, and the odor comes out from the drain of the sink. The cause of the smell of the gypsum trap is that the gypsum waste collected in the gypsum trap becomes sludge when mixed with human saliva and blood. It is interpreted that it decomposes the organic matter produced and generates a bad odor.

  In order to prevent this phenomenon, there are methods of regularly cleaning the gypsum trap or introducing a chemical such as a sterilizing deodorant that suppresses malodor.

  The aerobic microorganism group carrier 40 includes a carbonaceous material-containing hydrophilic porous plate material and / or an aerobic material in which an aerobic microorganism group is supported within a bag-shaped knitted fabric that supports the aerobic microorganism group. A microbial activator-containing hydrophilic porous plate material carrying a microorganism group is accommodated and formed into a plate shape (rectangular plate shape).

  The aerobic microorganism group used in the present invention is not particularly limited as long as it is useful for decomposing an organic substance contained in gypsum, and a microorganism group collected from soil is used. Examples of such microorganisms include bacteria belonging to the genus Pseudomonas, Streptomyces, Micrococcus, Nocardia, Achromobacter, Flavobacterium, Mycobacterium, Aerobacter, Nitrobacter, etc. The body is mentioned. These can be easily collected from soil such as seaside and riverside, preferably sandy land, and in the present invention, a group of microorganisms belonging to a plurality of genera is used. In addition, as an aerobic microorganism group used for this invention, you may use other various aerobic microorganism groups other than the said soil microbe (or together with the said soil microbe), for example, lactic acid bacteria.

  The material constituting the aerobic microorganism group carrier 40 is basically used by supporting the aerobic microorganism group. Knitted fabrics include polyvinyl alcohol synthetic fibers, protein fibers (natural fibers such as wool and silk, artificial protein fibers using casein, soybean protein, etc.), polyurethane synthetic fibers and polyamide synthetic fibers (such as nylon), A knitting process is performed using a thread or the like. This constitutes the outermost layer portion covering the aerobic microorganism group carrier 40.

The operation of depositing and drying to form a film is carried only once or a plurality of times. Note that the carrying on these members may be omitted.

  FIG. 5 is a perspective view of the outer container body 100A. As shown in the figure, the outer container body 100A is formed by molding a synthetic resin into a box shape having an open upper surface. The interior of the outer container main body 100 </ b> A serves as a storage portion 101 that stores the microorganism group holding main body 10. A holding portion 103 (see FIG. 5) that holds the support portion 25 of the case main body portion 21 by enclosing the periphery with a convex bank at a substantially opposite position at the center of two opposite surfaces of the inner peripheral surface of the storage portion 101. 5 shows only one).

  A drainage port 105 is formed on the other three sides 102 except for one long side 102 among the four upper sides 102 of the outer container body 100A. Four drain ports 105 are formed on the long upper side 102 and one on the two short upper sides 102. Each drain port 105 is provided with a substantially rectangular recess 107 on the upper side 102, a pair of substantially flat side walls 109 projecting outward on the left and right sides of the recess 107, and an outer surface on the bottom surface of the recess 107. A substantially flat bottom wall portion 111 projecting in the direction is provided. The protruding length of the bottom wall portion 111 is slightly shorter than the protruding length of the side wall portion 109, whereby a drainage portion 114 is formed in front of the bottom wall portion 111 that is shortened as shown in FIG. The front end side of the bottom wall portion 111 is bent in an approximately L shape downward, and the bent portion is a drainage guide portion 113.

  As shown in FIGS. 1 and 2, the lid 130 is formed by molding a synthetic resin into a substantially rectangular flat plate shape that closes the upper opening of the outer container body 100 </ b> A. A concave gypsum precipitating liquid reservoir 131 is formed at the center of the upper surface of the lid 130, and a bank-shaped edge 133 is formed around the gypsum precipitating liquid reservoir 131. The edge 133 has a substantially U-shaped cross section and is formed so that the opening faces downward. A water supply receiving surface 135 projecting upward is provided at the center of the bottom surface of the liquid reservoir 131 for gypsum precipitation. The water supply receiving surface 135 has a substantially dome shape, and has a curved shape so that the central portion is high and becomes lower toward the outer periphery.

  A substantially rectangular cover portion 137 that covers each drainage port 105 is formed at a position of the edge 133 of the lid 130 facing each drainage port 105. The cover part 137 protrudes from the outer peripheral surface of the edge 133 of the lid 130 and is formed in a substantially rectangular box shape with the lower surface released. The opening on the lower surface side of the cover portion 137 is formed in a size and shape that allows the pair of side wall portions 109 constituting the drainage port 105 to be inserted almost exactly.

  Four inflow ports 139 are provided on the inner peripheral side surface of one side where the cover portion 137 of the edge portion 133 of the lid 130 is not provided. The position of the lower side of the inflow port 139 is higher than the position of the bottom surface of the liquid reservoir 131 for gypsum precipitation.

  The fixture 170 is a suction cup.

  Next, the usage method of this malodor prevention tool 1-1 is demonstrated. FIG. 6 is a schematic view showing an example in which the malodor prevention device 1-1 is used by being attached to the inner surface of the sink 200. As shown in the figure, in this usage example, the attachment 170 of the malodor prevention device 1-1 is attached to the inner surface of the sink 200 by suction. The installation position of the malodor prevention device 1-1 is that the water discharged from the faucet 201 when the water faucet 201 is rotated to any position is the gypsum precipitation liquid reservoir on the top surface of the malodor prevention device 1-1. The position falls to 131. A downstream pipe 133 is connected to the lower part of the drain outlet of the sink 200, and a gypsum trap 250 is connected to the lower end thereof. The gypsum trap 250 is installed below the sink 200. Connected to the gypsum trap 250 is a downstream pipe 135 for draining water after separation of the gypsum.

  In a dental clinic, a dental laboratory, or the like, in the course of various operations using gypsum, part of the gypsum is washed away into the sink 200 with tap water. The washed water containing gypsum is discharged to the downstream pipe 133 and is once stored in the gypsum trap 250. In the gypsum trap 250, the gypsum component in the introduced water is settled and separated, and the subsequent water is drained to the downstream pipe 135.

  On the other hand, regularly (for example, several times to several tens of times a day), water (tap water) discharged from the tap 201 is dropped directly into the gypsum precipitation liquid reservoir 131 of the malodor prevention device 1-1. At this time, since the water reservoir receiving surface 135 having a substantially dome shape is formed in the gypsum precipitating liquid reservoir 131, water from the faucet 201 falls on this surface and water splash is prevented. Then, the water accumulated in the gypsum precipitation liquid reservoir 131 is introduced into the outer container 100 from the inflow port 139. Water is directly supplied from the faucet 201 to the gypsum precipitating liquid reservoir 131. For example, gypsum may be mixed with the supplied water when gypsum is attached to the hand that operates the faucet 201. However, since this water once accumulates in the gypsum precipitation liquid reservoir 131, gypsum accumulates on the bottom surface of the gypsum precipitation liquid reservoir 131, so that the gypsum component in water introduced into the outer container 100 from the inlet 139 is effective. Will be reduced.

  The water introduced into the outer container 100 substantially fills the outer container 100, and at this time, the entire microbial group holding body 10 shown in FIG. 3 is substantially submerged in water, and the aerobic microbial group carrier 40 and the microbial group holder 60. The aerobic microbes that have grown in them diffuse into the water. A part of the water containing the diffused aerobic microorganism group overflows from each drain port 105 at the top of the outer container 100 and is discharged to the outside, and is dropped into the sink 200. Then, water containing the aerobic microorganism group is introduced from the sink 200 into the gypsum trap 250. This aerobic microorganism group decomposes organic substances in the gypsum trap 250 and suppresses the propagation of various germs that generate malodors. As a result, malodor in the gypsum trap 250 is suppressed, and there is no possibility that this malodor will come out from the drain outlet of the sink.

  FIG. 7 is an enlarged perspective view of a main part of the drainage port 105 viewed from below. As shown in the figure, the drainage from the outer container 100 is performed from a drainage portion 114 that is an opening surrounded by a pair of side wall portions 109, a bottom wall portion 111, and a cover portion 137. The reason why the bottom wall portion 111 is provided is to prevent water discharged from the drainage portion 114 from being transmitted along the outer peripheral surface of the outer container 100. In particular, in this embodiment, since the drainage guide portion 113 is provided on the bottom wall portion 111, the water discharged more reliably can be prevented from being transmitted along the outer peripheral surface of the outer container 100. This can reliably prevent gypsum from adhering to the outer peripheral surface of the outer container 100.

  As described above, according to the malodor prevention device 1-1, the microorganism group holding body 60 is installed around the aerobic microorganism group carrier 40 that supports and propagates the aerobic microorganism group, At the same time, since water is once stored in the outer container 100 and then drained from the drain port 105, the space inside the aerobic microorganism group carrier 40 and the microorganism group holder 60 is always filled with water. It is an area where aerobic microorganisms are stably grown and maintained. A part of the water containing the aerobic microorganism group grown as described above can be stably supplied to the gypsum trap 200 from the drain 105, and the aerobic microorganism group decomposes the organic matter in the gypsum trap 200 and has a bad odor. Control the growth of germs that emit For these reasons, it is possible to prevent a bad odor generated from the gypsum trap 200 stably, easily, and at low cost over a long period of time.

  Moreover, since this malodor prevention tool 1-1 is attached to the inner surface of the sink 200 with the attachment 170, the bad smell prevention tool 1-1 can be installed in the position which does not interfere with various operations in the sink 200.

  The malodor prevention device 1-1 has a lid 130 that closes the outer container 100, and a concave gypsum precipitation liquid reservoir 131 is formed at a central portion of the upper surface of the lid 130, and the gypsum precipitation liquid reservoir 131. Since the inflow port 139 is provided on the inner peripheral side surface around the water, the water supplied to the gypsum precipitation liquid reservoir 131 on the upper surface of the lid 130 once accumulates in the gypsum precipitation liquid reservoir 131, and then the inflow port 139. Is introduced into the malodor prevention device 1-1. Therefore, even if the gypsum component is contained in the water, the gypsum component is precipitated when the water is stored in the liquid reservoir 131 for precipitation of gypsum, and the gypsum component introduced into the malodor control device 1-1 is reduced. be able to. As a result, the usable period of the malodor prevention device 1-1 can be extended.

  In addition, the malodor prevention device 1-1 stores the aerobic microorganism group carrier 40 in the carrier case 20 having the water inlet 22, and further holds the microorganism group holder 60 on the outer periphery of the carrier case 20. Since the piece 23 is formed, both the aerobic microorganism group carrier 40 and the microorganism group holder 20 can be easily and reliably held.

[Second Embodiment]
FIG. 8: is a perspective view of the malodor prevention tool 1-2 of the gypsum trap concerning 2nd Embodiment of this invention. In the malodor prevention device 1-2 shown in the figure, the same or equivalent parts as those in the malodor prevention device 1-1 shown in FIGS. 1 to 7 are denoted by the same reference numerals (provided with the suffix “-2”). Note that matters other than those described below are the same as those in the embodiment shown in FIGS.

  This malodor prevention device 1-2 is different from the malodor prevention device 1-1 only in the structure of the lid 130-2. That is, the lid 130-2 is formed by molding a synthetic resin into a substantially rectangular flat plate shape that closes the opening at the top of the outer container body 100A-2. The center of the lid 130-2 (the portion that has become the gypsum precipitation liquid reservoir 131 in the lid 130 of the malodor prevention device 1-1, that is, the central portion excluding the edge 133) is an inflow port 139-2 penetrating vertically. A gypsum intrusion prevention net 141-2 is installed so as to cover the entire inlet 139-2. The gypsum intrusion prevention net 141-2 is made of a fine mesh that allows water to pass through but does not allow gypsum components to pass through.

  When water (tap water) is supplied to the malodor prevention device 1-2 configured as described above regularly (for example, several times to several tens of times a day), this water is used for the gypsum invasion prevention net 141. -2 is introduced into the exterior container 100-2. The gypsum component may be mixed with the water supplied to the gypsum intrusion prevention net 141-2. However, the gypsum component remains on the gypsum intrusion prevention net 141-2 and is collected from the inlet 139-2. The gypsum component in the water introduced into the outer container 100-2 is effectively reduced.

  Since the flow and operational effects of water after water is introduced into the outer container 100-2 are the same as in the case of the malodor prevention device 1-1, description thereof is omitted.

[Third Embodiment]
FIG. 9 is a perspective view of a malodor prevention device 1-3 for a plaster trap according to a third embodiment of the present invention. In the malodor prevention device 1-3 shown in the figure, the same or equivalent parts as those of the malodor prevention device 1-1 shown in FIGS. 1 to 7 are denoted by the same reference numerals (provided with the suffix “-3”). Note that matters other than those described below are the same as those in the embodiment shown in FIGS.

  The malodor prevention tool 1-3 includes a microorganism group holding main body 10-3 and an outer container 100-3 for housing the microorganism group holding main body 10-3 (there is no cover and is configured by an outer container main body 100A-3). It comprises.

  The microorganism group holding body 10-3 houses the aerobic microorganism group carrier 40-3 in the carrier case 20-3 and surrounds the periphery of the carrier case 20-3. Is configured. The carrier case 20-3 has a substantially spherical and hollow case body portion 21-3 with a water inlet 22-3 extending from the outside to the aerobic microorganism group carrier 40-3 by communicating with the internal space. It is provided and configured. Since the aerobic microorganism group carrier 40-3 and the microorganism group holder 60-3 are both the same as the aerobic microorganism group carrier 40 and the microorganism group holder 60 of the malodor control device 1-1, the description thereof is omitted. Is omitted.

  The outer container body 100A-3 is formed by molding a synthetic resin into a circular box shape with an upper surface released. The outer container body 100A-3 has an outer diameter dimension shape that is housed and installed in a garbage receiving basket 205-3 described below. The inside of the exterior container main body 100A-3 is a storage portion 101-3 that stores the microorganism group holding main body 10-3. At the same height position on the outer peripheral surface of the outer container main body 100A-3, drainage ports 105-3 made up of eight circular through holes are formed at substantially equal intervals. The height position of each drain port 105-3 is a position near the upper part of the microorganism group holding body 10-3 stored in the outer container body 100A.

  FIG. 10 is a diagram illustrating a method of using the malodor prevention device 1-3. As shown in the figure, the malodor prevention device 1-3 is stored and installed in a garbage receiving basket 205-3 that is stored and installed in the drain 203-3 of the sink 200-3. Although not shown, a drain outlet lid is usually attached to the opening of the drain outlet 203-3 that houses the garbage receiving basket 205-3 and the malodor prevention tool 1-3.

  In a dental clinic, a dental laboratory, or the like, in the course of various operations using gypsum, part of the gypsum is washed away into the sink 200-3 with tap water. At this time, since the malodor prevention tool 1-3 is in the drain outlet 203-3, it does not interfere with various operations in the sink 200-3. The water containing the washed gypsum flows into the drain outlet 203-3, passes through the malodor control device 1-3 in the garbage receiving basket 205-3, is discharged to a downstream pipe (not shown), and is not shown. The gypsum component in the water is collected in the gypsum trap and then drained to the downstream side piping in the gypsum trap as in the case of the malodor prevention device 1-1.

  On the other hand, the water supplied into the storage unit 101-3 of the malodor prevention device 1-3 substantially fills the exterior container 100-3, and at this time, the microorganism group holding body 10-3 is substantially submerged in water, and aerobic microorganisms. The aerobic microorganism group grown in the group carrier 40-3 and the microorganism group holder 60-3 is diffused in water. A part of the water containing the diffused aerobic microorganism group is discharged to the outside from each drain port 105-3 of the outer container 100-3, and is introduced into the gypsum trap through the downstream pipe. This aerobic microorganism group decomposes the organic matter in the gypsum trap and suppresses the growth of miscellaneous germs that produce a bad odor, thereby suppressing the bad odor in the gypsum trap, and this bad odor is generated from the drain 203-3 of the sink 200-3. No fear of coming out.

  In the case of this malodor prevention device 1-3, water containing gypsum may enter the malodor prevention device 1-3 as it is, and the product life may be shortened. You may prevent this by attaching the same gypsum invasion prevention net | network 141-2 used by the malodor prevention tool 1-2 so that the upper opening of the accommodating part 101-3 may be covered. In addition, the gypsum component which accumulates on the upper part of the gypsum invasion prevention net | network flows along the outer wall surface of the malodor prevention tool 1-3, and is poured into the gypsum trap.

  In this example, the malodor prevention device 1-3 is housed and installed in the garbage receiving basket 205-3 installed in the drain port 203-3 of the sink 200-3.
