Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a garbage container for a sink, and more particularly to a triangular corner that is used by being placed in a corner of a kitchen sink or a strainer that is suitable for use in a strainer that is attached to a drain outlet of a sink.
[0002]
[Prior art]
As a conventional garbage container for a sink, one made of plastic or stainless steel material is widely used. In recent years, waste containers made of copper, antibacterial plastic, or antibacterial stainless steel have been provided for the purpose of preventing the occurrence of slimming, sliminess, and adhesion.
[0003]
[Problems to be solved by the invention]
Of these, antibacterial plastic waste containers contain several percent of silver and other antibacterial agents, and antibacterial stainless steel waste containers contain approximately 3% of copper. Due to the small amount, the antibacterial action is inferior to that of copper, and clogging of drain holes due to slime is likely to occur early. On the other hand, since the copper waste container is much more antibacterial than antibacterial plastic or antibacterial stainless steel, clogging is less likely to occur, but the copper surface is oxidized and discolored during use. In particular, the triangular corners are frequently watered and dried repeatedly, so the discoloration is significant, and there is a problem that may damage the aesthetics of the kitchen.
[0004]
Accordingly, an object of the present invention is to provide a sink container for a sink that is less likely to be clogged over a long period of time and is less likely to discolor due to its use.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the present invention has a coating layer on the surface of a container made of copper or a copper alloy, and a plurality of drain holes penetrating the container have copper or copper alloy in the drain hole. A sink container for a sink is provided which is formed so as to be exposed. As a result, the dust container surface is protected by the coating layer, so that the conventional discoloration is suppressed, while the antibacterial action of copper or copper alloy exposed in the drainage hole suppresses the growth of bacteria in the hole, and slimming. Clogging due to is also prevented for a long time.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0007]
FIG. 1 shows an example of a triangular corner which is an embodiment of the garbage container for a sink according to the present invention, and FIG. As shown in FIG. 1, the garbage container main body 1 is provided with a plurality of drain holes 3 penetrating therethrough. Here, as shown in a cross section in FIG. 2, the dust container body 1 includes a coating layer 12 having a predetermined thickness on the surface of a copper or copper alloy plate 11, while the dust container body 1, that is, the coating layer. 12, in each drain hole 3 penetrating the copper or copper alloy plate 11 and the coating layer 12, the surface of the copper or copper alloy plate 11 is exposed at the center of the inner surface of the drain hole 3.
[0008]
According to this form, since the surface of the garbage container main body 1 is protected by the coating layer 12, discoloration of copper or copper alloy due to repeated spraying and drying, which has been conventionally observed, is suppressed. In addition, based on the antibacterial action of copper ions by the copper or copper alloy plate 11 exposed in the drainage hole, the growth of bacteria in the drainage hole 3 is suppressed, and clogging due to slimming is prevented for a long time.
[0009]
The coating layer 12 is preferably zinc or tin . This is because zinc plating or tin plating is advantageous for forming a coating layer at low cost. Zinc is said to have the antibacterial action of metal ions in the order of mercury>silver>copper>zinc> iron lead> bismuth plating ("New Development of Healthcare Materials Development" Toray Research Center, Inc., Since the antibacterial action is superior to copper, as shown in page 72, the zinc coating layer itself is more advantageous because it exerts an antibacterial action in a weighted manner and contributes to preventing the occurrence of sliminess in the entire garbage container. Although tin is presumed to have no antibacterial effect, tin has good adhesion when plated on the surface of copper or copper alloy, and does not easily discolor and looks good. The thickness of the coating layer 12 is preferably about 5 to 20 μm.
[0010]
Draining hole 3, by forming a material having a coating layer on the plate 11 surface of the copper plate or a copper alloy is punched (punching), it is provided efficiently exposed surface of the copper or copper alloy draining hole 3 This is advantageous. After the desired drain hole 3 is formed, it can be finished by caulking to a shape as shown in FIG.
[0011]
It is preferable that the ratio (opening ratio) of the drainage hole 3 to the dust container main body 1 is 40% or more, and the exposed antibacterial action is ensured by increasing the exposed area of copper or copper alloy.
[0012]
In addition, by performing fine hole processing (for example, beam radiation) to mechanically or chemically and physically remove only the coating layer 12 on the surface of the copper or copper alloy plate 11 of the garbage container, The exposed area of copper or copper alloy may be further increased.
[0013]
FIG. 3 shows an example of a strainer which is another embodiment of the garbage container for a sink according to the present invention, and the same parts as those in the embodiment shown in FIG. The present embodiment is the same as the embodiment shown in FIGS. 1 and 2 except that the shape of the garbage container body 1 is different, and the details are omitted.
[0014]
【Example】
An embodiment of the garbage container for a sink according to the present invention will be described in detail below.
[0015]
A coating layer 12 made of zinc plating having a thickness of 5 μm was formed on the surface of a plate material 11 made of 99.96% copper having a thickness of about 0.5 mm. A water drain hole 3 having a diameter of about 1 mm was punched into this so that the aperture ratio was 46%, and the copper surface was exposed in the water drain hole 3. And the strainer for sinks of the shape shown in FIG. 3 was obtained by caulking molding.
[0016]
The strainer of the present invention was tested for discoloration, slime adhesion and clogging of drain holes. As a comparative example, a strainer composed entirely of antibacterial stainless steel was prepared, and both were used for 14 days under the usage conditions of a sink simulating a general household. The method of using the sink was to throw away the trash in the strainer and continue using it without removing the slime with a scrubber or sponge.
[0017]
As a result, in the comparative example, although there was no discoloration, the drainage hole was completely clogged on the 14th day due to adhesion of slime and drainage was impossible. On the other hand, in the present invention, there was no discoloration and almost no slime. Neither occurred nor clogged.
[0018]
【The invention's effect】
According to the present invention, the surface of a container made of copper or a copper alloy has a zinc-plated or tin-plated coating layer, and the plurality of drain holes penetrating the container are copper or copper alloy in the drain hole. Therefore, it is possible to provide a waste container for a sink that is less likely to be clogged over a long period of time and is less likely to be discolored during use.
