It has a structure (not shown) that is covered with a pair of eye plates. No. A is a garbage storage basket by removing the closed lid 800.
It can be thrown away at 500, and can be used to wash dishes, vegetables and fruits by filling with water when using the closed lid 800. The garbage can be thrown away.

[0003]

By the way, in A, it is not possible to secure a place in the sink A of the closed lid 800,
The removal work becomes troublesome each time, so the closed lid 80
It is the actual situation that the sink is removed and placed in another place and the sink is used.In addition, it is necessary to perform the dirty work of pushing in the garbage caught on the membrane plate 700, so use it with the membrane plate 700 removed. Along with the B, the inside of the garbage storage basket 500 and the inside of the sink A are communicated. Therefore, in both A and B, cockroaches, fly, mosquitoes, etc. enter the garbage storage basket, and it is easy to become unsanitary due to breeding, etc. In addition, the garbage to be stored can be seen as well as the unpleasant feeling due to the odor Dirtyness is perceived, and the usability of the sink is significantly reduced. In order to solve these problems, the present applicant has already proposed a drainage lid for sink (Japanese Utility Model Application No. 5-69934). This prior proposal has an annular frame that fits into a concave step portion that is recessed with a shape in a plan view slightly larger than the storage basket at the edge of the drainage basket on the garbage storage basket suspended in the drainage port, and its annular shape. An open / close lid is rotatably supported on the frame by an upwardly biasing spring hinge, and a structure including an engagement / disengagement operation unit for engaging and disengaging the open / close lid with the annular frame is provided between the open / close lid and the annular frame. It is set by fitting into the recessed step provided at the edge of the drain of the existing sink.When dumping garbage, operate the engaging / disengaging operation part to open the drain, and open and close it when the sink is not used. The lid closes the drain and prevents the outside air from flowing into the garbage storage basket, preventing cockroaches, fly and mosquito from entering. However, there is still room for improvement in future proposals. It is located on the front side of the sink, that is, in the central area where the sink is exclusively used when the sink is used, so that the opening and closing lid can be rotated in the back guard direction of the sink so as not to be in the way. There is a risk that the lid may be opened by mistake when performing dishwashing, vegetable / fruit washing, etc., and it is necessary to secure a space for taking out the garbage storage basket.

The pin portion 41c is locked to 41g, and the drain port 100 is kept closed. When the operating portion 91b is pushed against the reaction force of the compression spring material 41f, the reaction force increases, and the spring receiving plate 41e is rotated upward with the rising piece 41d 'as a fulcrum, and the spring receiving plate 41e is moved upward. Make the pin insertion hole 41g horizontal so that the pin
Release the lock with 41c. Then, the opening / closing lid 31 is instantly rotated upward by the spring force of the torsion spring 61 to open the drain port 100. At this time, the lower end of the downwardly curved portion of the rear end of the operation main body 91a is locked to the extension end of the extension portion 51, so that the obliquely rearward posture is maintained. On the other hand, when closing the drain port 100, the opening / closing lid 31 is turned downward against the spring force of the torsion spring 61 to forcibly force the pin insertion hole 41g of the spring receiving plate 41e.
It is sufficient to lock the pin portion 41c at that time, or otherwise push the opening / closing lid 31 downward in a state where the operating portion 91b is pushed and stop the pushing operation when the lid is covered.

The features of the third embodiment are the same as those of the second embodiment.

Next, a fourth embodiment and a fifth embodiment will be described. This embodiment is an example in which the space between the opening / closing lid 31 and the garbage storage basket 500 is effectively used.

The opening / closing lid 31 has an engaging rod portion (engaging portion) 31c having a large diameter portion at the tip end, protruding from the back side, and the engaging rod portion 31c.
A sponge, scourer and the like, which are cleaning tools 10 for the sink, are detachably locked, and an odor eliminating tool 20 such as an aromatic, a deodorant, a deodorant, and a bactericide is engaged with the locking rod 31c. Removably lock.

The cleaning tool 10 and the odor eliminating tool 20 include:
As shown in the figure, holes 10 ′ and 20 ′ for engaging and disengaging are opened, pulled out with a light force, and pushed in so as to be detachable from the opening / closing lid 31.

It is preferable that the sponge and the scallops have a shape that forms an outer peripheral surface with a diaper-shaped or U-shaped contour, and a shape in which the corner of a uniform sink is easy to wash.

The features of the fourth and fifth embodiments are that the space between the opening / closing lid 31 and the garbage storage basket 500 is flushed to remove the odor of the cleaning utensil 10 and garbage used for cleaning. That is, it can accommodate the odor eraser 20 that sterilizes the germs.

FIG. 17 shows the opening / closing lid 31 which is provided around the periphery by fitting a sealing material 31d around the periphery. Thus, the sealing material 31
When d is provided around, the sealing performance is further improved.

In all the embodiments, small drain holes may be formed in the opening / closing lid in a scattered manner. In this way, even when a small amount of washing is performed with the drain port closed, the water does not stay and rot.
