Description

  The present invention relates to a odor removal mechanism for sinks.

  As a sink odor removing mechanism that eliminates the odor of the sink drain outlet, there is a mechanism in which a chemical having a deodorizing action is directly provided on the back side of the lid covering the chrysanthemum lid provided on the upper part of the sink garbage receiving basket.

  By the way, the off-flavor removal mechanism deodorizes using the gas generated from the chemical, and the gas is one of the causes of deterioration of the rubber chrysanthemum crack lid.

  The present invention has been made in consideration of the above-mentioned matters, and an object of the present invention is to provide a odor removal mechanism for a sink that is difficult to deteriorate a chrysanthemum crack lid.

In order to achieve the above-mentioned object, the off-flavor removing mechanism of the sink according to the present invention is provided at the upper part of the dust receiving basket of the sink outlet, and has a plurality of tongue pieces that are narrower toward the center and have a hole at the root. A chrysanthemum lid with a vent hole, a cartridge that is detachably installed on the back side of the chrysanthemum lid, and a deodorant that is housed in the cartridge and that eliminates odors by adsorption through the vent hole An agent having an action, and means for closing the drain outlet space directly under the chrysanthemum lid ,
The cartridge is detachably installed in an annular groove formed on the rear surface of the chrysanthemum lid (Claim 1).

In this case, the agent rather is preferably in the range of deodorant inorganic, as the drug, for example, from Toagosei Co., Ltd. of Kesumon (TM) is used. This chemical is, for example, about 4 mm in granular form, and does not eliminate the bad smell at the drain outlet by chlorine gas generated from the chemical like another commercially available chlorine-type deodorant, but removes the bad smell by adsorption. It is. In addition, in the commercially available chlorine-based deodorant, the generated chlorine gas may be one of the causes of deterioration of the rubber chrysanthemum cracking lid, and health problems are caused by the chlorine gas. There is. However, since the inorganic deodorant used in the present invention has a function of eliminating a bad odor by adsorption, there is no such concern and the safety is high.

In this invention, it is preferable that the outer periphery of the cartridge is provided with a locking claw shaped to bite into the inner peripheral surface of the annular groove (Claim 2), and as means for closing the drain port space, It is preferable to provide a thin film covering the hole.

Further, in this invention, the chrysanthemum crack lid and / or the lid, it has preferred to form by addition of agents with drugs or antibacterial action to inhibit the formation of biofilms. Here, a biofilm is an aggregate of microorganisms surrounded by slime discharged from microorganisms, and is a thin film of slime. If this biofilm formation is inhibited, a great effect can be obtained in preventing the occurrence of slime. And as a chemical | medical agent which inhibits formation of a biofilm, there exists a dimer 38 (brand name; product made by Inui Co., Ltd.), and this does not generate | occur | produce a harmful | toxic gas and is highly safe with respect to a human body. The chemical | medical agent which inhibits formation of this biofilm has quaternary ammonium salt as a main component.
Further, as the drug having antibacterial action, for example, Kabinon (trademark) manufactured by Toa Gosei Co., Ltd. was used. This includes a hybrid (composite) material of an isothiazoline-based organic agent and a silica-based inorganic agent. Here, antibacterial is a concept including sterilization and sterilization.

  In this invention, since a deodorant that eliminates the off-flavor by adsorption is used as a chemical, there is no gas generation unlike other commercially available chlorinated deodorants, and there is a possibility that the rubber chrysanthemum crack lid will deteriorate. Disappear. And by the means for closing the drainage port space directly under the chrysanthemum lid, the off-flavor accumulated in the drainage port space can be effectively eliminated by adsorption.

In the state where the cartridge 20 is held by the chrysanthemum lid 1, the lower surface portion 20 b is exposed from the groove 18, and the numerous vent holes 22 face obliquely downward in the drain port space S.
Instead of the vent hole 22, one or more ring-shaped vent holes having a predetermined width formed in a size that prevents the medicine 19 from coming out may be provided on the lower surface portion 20 b. In the present invention, the means for holding the cartridge 20 to the chrysanthemum lid 1 is not limited to the groove 18 and the locking claw 21.

  Further, in this embodiment, the chrysanthemum crack lid 1 is formed by adding a coloring agent to EPDM as a main material and adding, for example, 1 to 3% by weight of a drug that inhibits the formation of a biofilm. . The chrysanthemum crack lid 1 may be formed by adding a colorant to EPDM and adding 2 to 10% by weight of a powdery agent having an antibacterial effect, or EPDM may contain a colorant. In addition, the chrysanthemum crack lid 1 may be formed by adding an appropriate amount of both a drug that inhibits the formation of a biofilm and a powdery drug having an antibacterial action.

Thus, the hole 9 of the chrysanthemum cracking lid 1 is covered with the thin film 17, and the apex portions 4a, 4a of the tongue piece 4 are brought into contact with each other to close the drain outlet space S immediately below the chrysanthemum cracking lid 1. And the off-flavor accumulated in the drainage space S can be effectively eliminated by adsorption. That is, it is possible to effectively eliminate the odor from the garbage receiving basket 7 , raw garbage adhering to the back side of the chrysanthemum crack lid 1, or sewage.

  Moreover, since the deodorant which removes a bad smell by adsorption | suction is used as the chemical | medical agent 19, there is no gas generation | occurrence | production like another commercially available chlorine-type deodorizing chemical | medical agent, and there is a possibility that the rubber chrysanthemum crack lid 1 may deteriorate. Disappear.

  Moreover, in this embodiment, the chrysanthemum crack lid 1 is formed by adding a drug that inhibits the formation of a biofilm or a drug having an antibacterial action, so that it is difficult for slime to occur in the chrysanthemum crack lid 1 for many years. .

  5 and 6 use the chrysanthemum cracking lid 1 in which the lower surface of the inner ring part 12 of the annular frame part 38 of the chrysanthemum cracking lid 1 and the lower surface of the ring part 13 outside the same are used, and immediately below the chrysanthemum cracking lid. Another embodiment of the present invention provided with a lid covering the chrysanthemum crack lid 1 as means for closing the drainage space S of the present invention is shown. 5 and 6, the same reference numerals as those used in FIGS. 1 to 4 are the same or equivalent.

The drug 33 is a water-soluble drug having a slime-removing action and / or a bactericidal action. Further, the drug 24 is a component that prevents the occurrence of copper rust (for example, benzotriazole, tolyltriazole, or mercapto). Benzothiazole).

  A drainage port 31 of the sink 30 is attached to and detached from a substantially cylindrical dust receiving basket storage container 34 whose downstream side is connected to a drain pipe (not shown) and an upper space S in the storage container 34. A bottomed and substantially cylindrical dust receiving basket 32 which is freely accommodated, and a rubber chrysanthemum cracking lid 1 which is used by being fitted into the upper opening 34a of the accommodating container 34 so as to cover the dust receiving basket 32. And is equipped. A lower portion of the garbage receiving basket container 34 is formed in a trap T. A known container is used as the container 34. The container 34 is installed in the drain port 31 by holding an outward flange 36 provided on the annular upper end peripheral surface portion 35 forming the upper opening 34 a on the upper end inner peripheral surface portion Q of the drain port 31. . As shown in FIG. 6, the chrysanthemum lid 1 has a plurality of chrysanthemum tongues 36 at the bottom 5, for example, a small round hole 37 at the center of the bottom 5, and a plurality of chrysanthemum lids 32 communicating with the dust receiving basket 32. A hole 9 is provided at the base of the tongue piece 36 so that dust accumulated in the basket 32 is difficult to see. Reference numeral 38 denotes an annular frame portion that forms the upper opening 38 a of the chrysanthemum crack lid 1, 39 denotes an inner peripheral surface of the annular frame portion 38, and 40 denotes an outer peripheral surface of the annular frame portion 38. Then, the chrysanthemum crack lid 1 is fitted into the upper opening 34 a of the storage container 34 so that the outer peripheral surface 40 and the inner peripheral surface 41 of the upper end peripheral surface portion 35 abut.

  The dust receiving basket 32 is mainly configured by a mesh-shaped bottom portion 42 having a circular shape in plan view, a cylindrical mesh-shaped trunk portion main body 43, and an annular upper end peripheral surface portion 44 continuously provided upward from the trunk portion main body 43. Has been. Reference numeral 44 a denotes an upper opening of the dust receiving basket 32, which is formed by the upper end peripheral surface portion 44. Further, the upper end peripheral surface portion 44 is provided with an outward flange 45, and this outward flange 45 abuts on a step surface 47 provided on the lower inner peripheral surface of the upper end peripheral surface portion 35 of the dust receiving basket containing container 34. By being held in a state, a garbage receiving basket 32 is installed in the container 34.

  In this embodiment as well, in the same manner as in the above embodiment, the annular groove 18 formed on the back surface of the ring portion 12 has a large number of granular inorganic chemicals having a deodorizing effect of about 4 mm [for example, the above-mentioned Toa Gosei Co., Ltd. A ring-shaped cartridge 20 containing a company-made Kesmon (trademark)] 19 is detachably installed. Then, the downward projecting length L from the lower surface of the ring portion 12 at the bottom b of the lower surface portion 20b is set to such a length that the bottom b of the lower surface portion 20b does not contact the upper surface 45a of the outward flange 45 of the dust receiving basket 32. Yes.

  And in this Example, the cover 50 which covers the chrysanthemum crack cover 1 is provided as a means to close the drain outlet space S just under a chrysanthemum crack cover. The lid 50 is formed by adding a drug that inhibits the formation of a biofilm or a drug having an antibacterial action.

  Thus, a part of the drainage of the sink flows into the housing part 34 to dissolve a part of the medicine 33, and the dissolved solution reaches from the inside of the housing part 34 to the dust receiving basket 32 directly below the waste receiving basket 32. For example, the slime can be removed and the occurrence of copper rust can be prevented, so that the antibacterial function of the garbage receiver 3 can be prolonged. At this time, the solution that travels on the surface of the solution guide piece 52 provided in the storage portion 34 falls directly to the bottom 42 and also from the solution guide piece 52 to the body portion 43, so that the solution is surely received. It reaches the mesh portions 42 and 43 other than the upper peripheral surface portion 44. And in the state where drainage has run out, that is, in the state where drainage no longer flows into the storage part 34, a part of the medicine 33 is dissolved by the drainage that has flowed into the storage part 34 first, Since the inflow hole 34a provided in the accommodating part 34 is provided at a position lower than the outflow hole 34b provided in the accommodating part 34, the waste water is accumulated in the accommodating part 34, and the dissolved liquid easily becomes a saturated liquid. . That is, dissolution of the drug 33 is stabilized. If there is drainage in this state, the solution dissolves in the form of diluting the saturated solution and mixed with the saturated solution to flow out of the storage portion 34. Therefore, for example, the slime of the dust receiving basket 32 can be effectively removed and the occurrence of copper rust can be prevented.

  Furthermore, by covering the chrysanthemum lid 1 with the lid 50, the drainage space S immediately below the chrysanthemum lid 1 can be closed, and the off-flavor accumulated in the drainage port space S can be effectively eliminated. That is, it is possible to effectively eliminate the bad smell from the garbage receiving basket 4, the garbage attached to the back side of the chrysanthemum cracking lid 1, or the sewage.

  Moreover, since the deodorant which removes a bad smell by adsorption | suction is used as the chemical | medical agent 19, there is no gas generation | occurrence | production like another commercially available chlorine-type deodorizing chemical | medical agent, and there is a possibility that the rubber chrysanthemum crack lid 1 may deteriorate. Disappear.
