Description

  The present invention relates to a sink drainage mechanism.

  As shown in FIGS. 10 and 11, the waste outlet 70 a of the sink 70 is, for example, a synthetic resin-wrapped garbage receiving basket containing container 71 that is attached so that the downstream side is connected to the drain pipe, and the containing container 71. A synthetic resin dust receiving basket 72 that is detachably accommodated in the container, and a synthetic resin chrysanthemum lid 73 that is fitted into the upper portion of the container 71 and used to cover the dust receiving basket 72 is provided. It has been. FIG. 10 shows a state where the chrysanthemum lid 73 is not attached. The chrysanthemum crack lid 73 has a plurality of chrysanthemum tongues 74 at the bottom, for example, a small drainage round hole 75 at the center of the bottom, and a plurality of small drainage for communicating with the mesh-like dust receiving basket 72. It has a shape with a long hole 76 that makes it difficult to see dust accumulated in the basket 72.

By the way, there exists a thing shown in the following patent document 1 as the chemical | medical agent installation member 78 for chrysanthemum lids detachably installed with respect to the chrysanthemum lid 73. As shown in FIG. 12, the chrysanthemum lid lid chemical setting member 78 is formed in a ring shape, for example, by joining a thin upper ring member 79 and a thin lower ring member 80. 73 is detachably attached to 73. Reference numeral 81 denotes a joint surface between the upper ring member 79 and the lower ring member 80. The lower ring member 80 has a plurality of locking pieces 82 that are locked to the inner peripheral surface i of the annular frame portion 73a of the chrysanthemum lid 73 on the outer peripheral surface at appropriate intervals in the circumferential direction. Further, the chrysanthemum lid lid chemical installation member 78 is a sterilizing agent, or a deodorizing agent that eliminates odors from garbage and sewage collected in the garbage receiver basket 72 and chrysanthemum lid 73 ( The inner peripheral surface of the chrysanthemum crack lid 73 has a plurality of storage portions 83 for storing (hereinafter simply referred to as drugs) (not shown), and each of the storage portions 83 is positioned in the drainage long hole 76. By biting into i, the chrysanthemum lid cover 73 is elastically fitted and held inside the chrysanthemum lid 73. Then, in order to stabilize the dissolution of the drug by the waste water, the storage part 83 has an inflow hole 84 of the waste water flowing into the storage part 83, and the drug solution flowing out of the storage part 83 from the outflow hole 85. In this way, the chrysanthemum crack lid 73 and the dust receiving basket 72 can be sterilized to remove slime.
Japanese Patent No. 3520073

  That is, the drainage of the sink reaches the dust receiving basket 72 through the drainage long hole 76 formed at the bottom of the chrysanthemum cracking lid 73. At this time, the drainage of the sink flows into the drainage inflow holes 84 of each housing portion 83 to dissolve a part of the medicine, and the force of the drainage flowing into the drainage inflow hole 84 causes the chrysanthemum lid lid medicine installation member. The dissolved solution reaches the bottom of the chrysanthemum crack lid 73 from the dissolved solution outflow hole 85 located at a position higher than the drainage inflow hole 84 on the radially outer side of 78, and reaches the garbage receiving basket 72 through the drainage long hole 76. A portion of the waste water stays on the chrysanthemum tongue piece 74. Therefore, it is possible to eliminate raw trash adhering to the garbage receiving basket 72 or a strange odor from the sewage, or sterilizing the garbage receiving basket 72 to remove the slime adhering to the garbage receiving basket 72. At the same time, raw garbage adhering to the chrysanthemum lid 73 provided on the upper part of the garbage receiving basket 72 or an unpleasant odor from the sewage can be eliminated, or the chrysanthemum crack lid 73 is sterilized, and the chrysanthemum crack lid 73 is removed. The slime adhering to can be removed. And once the drainage is exhausted, that is, when the drainage does not flow into the housing 83, part of the medicine is dissolved by the wastewater that has flowed into the housing 83 first, and Since the waste water is accumulated in the accommodating portion 83, the solution is likely to become a saturated solution and the dissolution of the drug is stabilized. If there is drainage in this state, the solution dissolves in the form of diluting the saturated solution and flows out of the solution outflow hole 85 mixed with the saturated solution. Accordingly, it is possible to effectively eliminate the bad odor from the garbage receiving basket 724 and the chrysanthemum lid 73 or the sewage, and to effectively sterilize the dust receiving basket 72 and the chrysanthemum lid 73. This can effectively remove the dirt adhering to the dust receiving basket 72 and the chrysanthemum lid 73.

  Further, on the bottom of the chrysanthemum lid 73, the chrysanthemum lid cover drug installation member 78 is removed from the chrysanthemum lid 73 and covers the upper opening m of the chrysanthemum lid 73 as shown in FIGS. A lid 86 made of synthetic resin may be installed. The lid 86 includes a lid top plate 87 having a circular shape in plan view, and an annular hanging plate 88 continuously provided downward from the outer peripheral edge of the lid top plate 87. When the lid 86 is installed on the bottom of the chrysanthemum crack lid 73, the outer peripheral surface of the hanging plate 88 becomes smaller in diameter as it goes downward so as to be fitted into the inner peripheral surface i of the annular frame portion 73a so as to be sealable. It is formed in the taper surface which inclines so. Therefore, water, hot water, or mixed water can be stored in the sink A of the sink 70 without leaking from the drainage long hole 76 and the round hole 75.

  Further, as shown in FIG. 15, the annular frame portion 73a of the chrysanthemum crack lid 73 has a substantially comb-shaped longitudinal section and is adjacent to each other via, for example, two annular grooves 90, 91 formed concentrically downward. Three ring portions 92, 93, 94 are provided. With these three ring portions 92, 93, 94, it is possible to cope with the case where there are three types of diameters of the drainage outlet 70a (for example, Φ150mm, Φ142mm, Φ134mm).

  However, for example, in the chrysanthemum lid 73, the chrysanthemum crack lid 73 has a relationship between the shape of the chrysanthemum crack lid 73 and the installation position of the chrysanthemum lid lid medicine installation member 78 on the chrysanthemum lid 73. There are places where it is difficult for the solution to flow. For example, it is difficult to remove the slime in the two annular grooves 90 and 91 of the annular frame portion 73a with a solution, which is unsanitary, and countermeasures have been desired.

  The present invention has been made in consideration of the above-mentioned matters, and an object of the present invention is to provide a drainage mechanism for a sink that can prevent the occurrence of slime even at a place where a solution of a drug having a bactericidal action does not reach. is there.

  In order to achieve the above object, the drainage mechanism of the sink of the present invention is provided at the upper part of the drainage outlet in a state of covering the dust catching basket made of synthetic resin installed at the drainage outlet of the sink. Of a synthetic resin or rubber chrysanthemum cover, and a synthetic resin chrysanthemum lid covering lid that is detachably attached to the chrysanthemum cover and collects water in the sink of the sink. In the drainage mechanism, at least one member of the garbage receiving basket, chrysanthemum lid, and chrysanthemum lid covering lid is formed by adding a drug that inhibits the formation of a biofilm or a drug having an antibacterial action. (Claim 1).

  The sink drainage mechanism according to the present invention includes a synthetic resin dust receiving basket installed at a sink drainage outlet, and is provided above the drainage outlet so as to cover the dust receiving basket. In a sink drainage mechanism comprising a synthetic resin dust scraping lid for scraping off dust collected in the container, at least one of the dust receiving basket and the dust scraping lid is a drug that inhibits the formation of a biofilm or Provided is a sink drainage mechanism formed by adding a drug having an antibacterial action (claim 2).

  Here, a biofilm is an aggregate of microorganisms surrounded by slime discharged from microorganisms, and is a thin film of slime. If the formation of this biofilm 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.

  In the present invention, for example, Kabinon (trademark) manufactured by Toa Gosei Co., Ltd. was used as a drug having an antibacterial action. This includes a hybrid (composite) material of an isothiazoline-based organic agent and a silica-based inorganic agent.

  Then, these members are formed by changing the amount of each agent added and various conditions including raw materials for the chrysanthemum lid, chrysanthemum lid covering lid, garbage receiving basket, dust scraping lid, and antibacterial effect on these The present inventors diligently studied whether or not there was any.

  As a result, taking the chrysanthemum crack lid as an example, the following was found. That is, the said chemical | medical agent is added to the main raw material of a chrysanthemum crack lid | cover, for example, ethylene propylene diene type rubber (EPDM).

(A) First, the present inventors have found that in the case of a drug that inhibits the formation of the biofilm, the addition amount is set to 1 to 3% by weight, and the effect is sufficiently obtained.
Here, the upper limit of the addition amount of the drug that inhibits the formation of the biofilm is 3% by weight because the biofilm is used as a main raw material for chrysanthemum cracking lid if the addition amount is more than 3%. This is because it is difficult to uniformly mix a drug that inhibits the formation of the.
Moreover, the reason why the lower limit value of the amount of the drug that inhibits the formation of the biofilm is set to 1% by weight is that if the amount is less than 1%, the effect of inhibiting the formation of the biofilm tends to decrease. .
In addition, the present inventors have confirmed that the same results can be obtained, for example, with respect to a garbage receiving basket made mainly of polypropylene (PP), a lid for covering a chrysanthemum lid, and a lid for dust scraping.

(B) Next, taking the chrysanthemum lid as an example, in the case of the drug having the antibacterial action, the present inventor has a sufficient effect by setting the addition amount to 2 to 10% by weight ratio. Found. Here, the upper limit value of the addition amount of the antibacterial agent is 10% by weight. If the amount is more than 10%, the antibacterial agent is hardly mixed uniformly with the main raw material of the chrysanthemum lid. Because it becomes.
Moreover, the reason why the lower limit of the addition amount of the antibacterial agent is set to 2% by weight is that the antibacterial effect tends to be reduced if it is less than 2%.
In addition, the present inventors have confirmed that the same results can be obtained, for example, with respect to a garbage receiving basket made mainly of polypropylene (PP), a cover for covering a chrysanthemum lid, and a cover for dust scraping.

  In this invention, at least one member of a synthetic resin-made garbage receiving basket, a synthetic resin or rubber chrysanthemum lid, a synthetic resin chrysanthemum lid covering lid, Since it is formed by adding a drug having antibacterial action, at least one member among the three members is a chrysanthemum lid drug setting member, a dust receiving basket drug setting member or a lid drug setting member. It is possible to prevent slime from occurring at a location where a solution of a drug having a slime-removing action accommodated in the container does not reach. In addition, even when a chrysanthemum lid chemical setting member, a dust receiving basket chemical setting member or a lid chemical setting member is not provided, it is difficult to adhere slime to at least one of the three members for many years. The one member is hygienic, and when the one member is cleaned, the cleaning operation can be performed more quickly than the other two members, and the one member can be prolonged.

  Further, in the present invention, at least one of the garbage receiving basket and the synthetic resin garbage scraping lid is formed by adding a drug that inhibits the formation of a biofilm or a drug having an antibacterial action. About at least one member of the dust receiving basket and the dust scraping lid, a portion where the drug solution having at least slime removing action accommodated in the dust receiving basket drug installing member or the lid drug installing member does not reach However, it is possible to prevent slime from occurring. Further, even when the medicine receiving member for the garbage receiving basket or the medicine installing member for the lid is not provided, it is possible to make it difficult to adhere to the slime for at least one of the two members for many years. In addition, when the one member is cleaned, the cleaning operation can be performed more quickly than the other members, and the one member can be made longer.

Can store hot water or mixed water.

  The characteristic configuration of the present invention will be described below.

  The chrysanthemum crack lid 1 on which the drug installation member 12 is set is formed by adding a coloring agent to a raw material, for example, EPDM, and adding, for example, 1 to 3% by weight of a drug that inhibits biofilm formation. ing. 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.

  In addition, the dust receiving basket 4 and the chrysanthemum lid covering lid 30 each contain a colorant in a raw material, for example, polypropylene (PP), and, for example, a drug that inhibits the formation of a biofilm in a weight ratio of 1 to It is formed by adding 3%. In addition, by adding a colorant to polypropylene (PP) and adding 2 to 10% by weight of a powdery agent having an antibacterial action, the dust receiving basket 4 and the chrysanthemum lid covering lid 30 are formed. Alternatively, a colorant may be included in polypropylene (PP), and an appropriate amount of both a drug that inhibits the formation of a biofilm and a powdery drug that has an antibacterial action may be added, and You may form the lid | cover 30 for chrysanthemum crack cover.

Further, in this embodiment, among the chrysanthemum lid 1, the garbage receiving basket 4 and the lid 30, a chemical (deodorant) having a deodorizing action for eliminating a bad odor from raw garbage and sewage is applied to the lid 30 in a weight ratio. 2 to 10% is added. As the deodorant, for example, Kesmon (trademark) manufactured by Toa Gosei Co., Ltd. is used.
This deodorant is an inorganic deodorant that eliminates the odor from the drainage by adsorption, instead of erasing the odor at the drainage port with chlorine gas generated from the drug as in another commercially available chlorinated deodorant. Moreover, although the said commercially available chlorine-type deodorizing chemical | medical agent is mounted and used, for example in the garbage receptacle basket 4, the said generated chlorine gas may become one of the causes of deterioration of the rubber chrysanthemum crack lid 1. There is also a problem that health problems are caused by the chlorine gas. However, since the inorganic deodorant used in this embodiment has a function of eliminating a bad odor by adsorption, there is no such concern and the safety is high. The chrysanthemum crack lid 1 and the dust receiving basket 4 may also be formed by adding the inorganic deodorant.

  Thus, by the solution of the medicine 13 flowing out from the container 17 of the chrysanthemum lid medicine installation member 12, the garbage adhering to the garbage receiving basket 4 and chrysanthemum lid 1 as in the past, or The odor from the sewage can be eliminated, or the dust receiving basket 4 and the chrysanthemum cracking lid 1 can be sterilized to remove the slime adhering to the dust receiving basket 4 and the chrysanthemum cracking lid 1.

  Moreover, in the present invention, since the chrysanthemum crack lid 1 is formed by adding a drug that inhibits the formation of biofilm or a drug having antibacterial action, slime is generated for many years even in places where the solution of the drug 13 does not reach. It can be difficult. For example, the slime is conventionally attached to the two annular grooves 8c and 8d of the annular frame 8 of the chrysanthemum lid 1. However, in the present invention, it is possible to prevent the slime from occurring in the annular grooves 8c and 8d. At the same time, the occurrence of slime in the chrysanthemum crack lid 1 can be suppressed for many years. Further, according to the present invention, it is possible to suppress the occurrence of slimming in the garbage receiving basket 4 for many years. In addition, the lid 30 covering the chrysanthemum crack cover 1 when the sink 2 of the sink 2 is not used or when the sink 2 is not used is added with a drug that inhibits the formation of a biofilm or a drug having an antibacterial action. Therefore, it is possible to prevent the lid 30 from being slimmed for many years.

The present invention is also applicable when a drug that inhibits the formation of a biofilm or a drug that has an antibacterial action is added to only one member of the garbage receiving basket 4, chrysanthemum lid 1 and lid 30 covering chrysanthemum lid 1. Is applicable. In addition, the present invention is also applicable when a drug that inhibits the formation of a biofilm or a drug having an antibacterial action is added to any two members of the garbage receiving basket 4, chrysanthemum lid 1 and lid 30 covering chrysanthemum lid 1. Applicable.
The present invention can also be applied to the case where a dust receiving basket drug installing member is set in the dust receiving basket 4 or the lid drug installing member is set in the chrysanthemum lid covering lid 30.
Further, the deodorizing treatment may be applied to the dust receiving basket 4 and / or the chrysanthemum cracking lid 1.
