Effects and effects of the invention

  As described above, the present invention has a plug body capable of closing the outlet at the bottom of the drainage container and an overflow pipe penetrating vertically through the outlet, and sets the plug body in a state in which the outlet is closed. In the drainage container, a water faucet that allows water to be accumulated up to the water level at the upper end of the overflow pipe is provided. According to the first aspect, the water can be easily placed inside the drainage container by simply setting the water faucet. Can be stored.

Therefore, by pouring detergent into the drainage container from the sink, the interior of the drainage container can be immersed and washed.
This makes it possible to easily remove dirt such as slime adhering to the inside of the drainage container, so that the inside of the drainage container can always be kept clean, and the problem that the inside of the drainage container becomes a source of odor can be solved. .

  According to the first aspect of the present invention, it is not necessary to use a drain valve such as an electromagnetic valve that is likely to break down as a means for accumulating water in the drain container, and maintenance is easy, and drainage comprising an electromagnetic valve or the like. By providing the valve, the structure of the drainage device is not complicated, and the required cost can be reduced.

  In this first aspect, the water stopper is provided with an overflow pipe, and since the overflow pipe is installed at the same time as the outlet of the drainage container is closed with a stopper, a sink is provided to collect water inside the drainage container. Even if water is allowed to flow from a sink tap, etc., the water level of the accumulated water is the overflow port of the overflow pipe, for example, the upper end opening (the overflow port is not necessarily the upper end opening, but the upper end opening is represented below) (Explained as an example), excess water overflows into the overflow pipe and is discharged to the outside through the overflow pipe and drain pipe, so it is ensured that the water will overflow from the sink if you forget to stop the water. Can be prevented.

Here, it is desirable that the overflow pipe has a height at the upper end opening (that is, the overflow port) so that water can be accumulated in the entire interior of the drainage container.

At that time, the opening / closing lid 40 of the mesh cage 18 is pushed upward by the overflow pipe 48 to open the opening 38 at the bottom of the mesh cage 18, and the overflow pipe 48 is inserted upward with respect to the opening 38.
FIG. 5B shows the state at this time.

When water is caused to flow from the sink faucet 14 toward the sink 12 in this state, water from the sink faucet 14 is accumulated in the drainage container 16.
When the level of the accumulated water reaches the upper end of the overflow pipe 48, excess water that has flowed from the sink water faucet 14 thereafter overflows into the overflow pipe 48, and then flows down into the overflow pipe 48 to drain the drain pipe. 32 is discharged to the outside.
That is, even if the water is left out of the sink faucet 14, there is no fear that the water will overflow from the inside of the sink 12.

  Now, after the water is accumulated in the water reservoir 16 in this way, a detergent is poured into the drainage container 16 and left for a predetermined time, so that the interior of the drainage container 16 and the entire mesh basket 18 accommodated therein are removed. It can be soaked and washed to remove stains such as slime adhering to them.

  After soaking and washing as described above, the net basket 18 is first taken out from the drainage container 16, and then the water tap 42 is pulled out and removed from the drainage container 16, and then rinsed with water and then the net again. The car 18 is stored in the drainage container 16.

The above is the case where the diameter of the opening 38 of the mesh basket 18 is smaller than the plug 44 of the water stopper 42, but the diameter of the opening 38 can be made larger than the plug 44.
In this case, by opening the open / close lid 40 with the mesh basket 18 housed in the drainage container 16, the water reservoir stopper 42 is directed from the lower end plug 44 to the opening 38 of the mesh basket 18 from above in the drawing downward. The plug 44 can be set in a state in which the outlet 30 at the bottom of the drainage container 16 is closed.
Therefore, after that, by letting water flow from the sink water faucet 14 toward the drainage container 16, the state shown in FIG. 5B, that is, the state where water is accumulated inside the drainage container 16 can be obtained.
The opening / closing lid 40 may be biased in the closing direction by a spring or the like.

As described above, according to this embodiment, water can be easily stored in the drainage container 16 simply by setting the water stopper 42.
Therefore, by pouring detergent into the drainage container 16 from the sink 12, the inside of the drainage container 16 and the net cage 18 accommodated therein can be immersed and washed.
As a result, dirt such as slime adhering to the inside of the drainage container 16 and the net basket 18 can be easily removed, and the inside of the drainage container 16 and the net basket 18 can be always kept clean. The problem that 18 becomes a generation source of an odor can be solved.

  Further, in this embodiment, it is not necessary to use a drain valve such as an electromagnetic valve that is likely to fail as a means for accumulating water inside the drain container 16, and maintenance is easy, and a drain valve composed of an electromagnetic valve or the like is provided. Thus, the structure of the drainage device is not complicated, and the required cost can be reduced.

  In the present embodiment, the water reservoir plug 42 is provided with an overflow pipe 48, and the outlet pipe 30 of the drainage container 16 is closed by the plug body 44 and the overflow pipe 48 is installed at the same time. Even if the water flows into the sink 12 and the water faucet 14 or the like flows in order to collect water, when the water level reaches the upper end of the overflow pipe 48, excess water overflows into the overflow pipe 48. Since the water is discharged to the outside through the overflow pipe 48 and the drain pipe 32, it is possible to reliably prevent the water from overflowing from the sink 12 due to forgetting to stop the water.

  In this embodiment, an opening 38 through which the overflow pipe 48 is inserted is provided at the bottom of the mesh basket 18, and an opening / closing lid 40 that opens and closes the opening 38 is provided in the mesh basket 18. Since the net cage 18 can be accommodated in the drainage container 16 even underneath, the net cage 18 can be immersed and washed together with the inside of the drainage container 16, and dirt such as slime can be washed and removed at the same time.

Further, since the mesh basket 18 is provided with an opening / closing lid 40 for opening and closing the opening 38 of the bottom portion 22, the opening is normally stored in the drainage container 16 with the opening 38 closed by the opening / closing lid 40. be able to.
Here, since the opening / closing lid 40 is attached to the bottom 22 of the mesh basket 18 so as to be opened and closed, there is no need to attach / detach the opening / closing lid 40 to / from the mesh basket 18, and the opening / closing lid 40 once removed from the mesh basket 18. There is no risk of losing.

  Further, since the opening / closing lid 40 has a drainage hole for draining water, the water inside the opening / closing lid 40 is discharged through the water passage hole of the opening / closing lid 40 even when the opening 38 of the bottom portion 22 is closed by the opening / closing lid 40. Can be drained.

In this example, the opening / closing lid 40 is attached to the lower surface (back surface) of the bottom portion 22 of the net cage 18 so as to be opened and closed.
In this embodiment, the diameter of the opening 38 is larger than that of the plug body 44 of the water reservoir plug 42.
In this embodiment, the opening / closing lid 40 is biased in the closing direction, that is, upward in the figure.

FIG. 7 shows the operation of this embodiment.
In this example, the lid 40a of the open / close lid 40 of the mesh basket 18 is pushed downward by the plug body 44 at the tip of the water reservoir stopper 42 while the mesh cage 18 is accommodated in the drainage container 16 to open it. As a result, the water stopper 42 can be set while the mesh basket 18 is housed inside the drainage container 16. That is, the water tap 42 can be set so that the outlet 30 of the drainage container 16 is closed by the plug 44.
Thereafter, water can be stored in the drainage container 16 by discharging water from the sink faucet 14.

In this embodiment as well, the inside of the drainage container 16 and the net basket 18 can be washed by injecting detergent under a state where water is accumulated in the drainage container 16. By pulling this upward, the water tap 42 can be taken out from the drainage container 16.
However, in this embodiment, since the opening / closing lid 40 is biased in the closing direction, the opening / closing lid 40 is opened to some extent so as not to interfere with the plug body 44 of the water holding stopper 42 when the water holding stopper 42 is pulled upward. In this state, the water stopper 42 is pulled out upward.

8 and 9 show still another embodiment of the present invention.

Here, the rubber opening / closing lid 50 is formed in a circular thin plate shape as a whole, and a large number of cuts 52 are formed radially from the center (see FIG. 8B). The intermediate portion is an elastic piece 54 having a planar triangular shape.
Therefore, in this embodiment, the opening 38 can be opened by pushing the elastic pieces 54 upward or downward and elastically deforming the elastic pieces 54.
Further, by removing the force, the elastic piece 54 can be returned to its original shape, and the opening 38 can be closed.

  FIG. 9 shows the operation of this embodiment. In this embodiment, for example, the diameter of the opening 38, strictly speaking, the size of the open portion obtained by elastic deformation of the elastic piece 54 is smaller than that of the plug body 44. In order to collect water in the drainage container 16, the net cage 18 is first removed, and in this state, a water stopper 42 is set as shown in FIG.

After that, the elastic piece 54 of the open / close lid 50 is elastically bent and deformed upward by the overflow pipe 48 of the water reservoir stopper 42, and the mesh basket 18 is pushed into the drainage container 16 to be accommodated therein.
Thereafter, water is accumulated in the drainage container 16. The action at that time is the same as described above.
In order to remove the water tap 42, the net cage 18 is once taken out from the drainage container 16, and then the water tap 42 in a set state is pulled upward and taken out from the drainage container 16. After rinsing with water, the mesh basket 18 is again housed in the drainage container 16.

  On the other hand, when the diameter of the opening 38 (in this case, strictly, the size of the open portion caused by the deformation of the elastic piece 54) is larger than the plug 44 of the water reservoir 42, the mesh basket 18 is placed inside the drainage container 16. In a state where the outlet 30 is closed by the rubber plug 44 while the water stopper 42 is pushed downward from above and the elastic piece 54 of the rubber opening / closing lid 50 is bent and deformed downward, Set the water tap 42.

In this state, water is stored inside the drainage container 16, the interior of the drainage container 16 and the net basket 18 are immersed and washed, and then the water stopper 42 is pulled out as it is, so that it can be taken out from the drainage container 16 to the outside. it can.
When the water tap 42 is pulled upward in the drawing, the plug 44 at the lower end of the water tap 42 hits the open / close lid 50. Since it is elastically deformed upward and opened, the water stopper 42 can be pulled out as it is.

In addition, when it is desired to provide a water drain hole for draining in the opening / closing lid 50, the opening / closing lid 50 can be configured in the form as shown in FIG.
In the example of FIG. (C), the cut 52 in FIG. 8 (B) is formed in a slit shape, and a water passage hole 56 for draining water is formed by the slit, and a hole-shaped water passage hole 58 is also formed at the base of the cut. Further, a circular hole-shaped water passage hole 60 is also formed in the central portion of the opening / closing lid 50, that is, on the distal end side of each elastic piece 54.
However, these water passage holes 56, 58, 60 are selected to have a size that prevents garbage from passing through.

  Although the embodiments of the present invention have been described in detail above, these are merely examples, and the present invention can be configured in various modifications without departing from the spirit of the present invention.
