Description

[Detailed explanation of the idea] The present invention relates to a kitchen sink.

Generally, in a kitchen sink, a cylindrical storage tank is installed at the drain port at the bottom of the washing tank, and a porous drainer is fitted into the storage tank to drain food waste such as vegetable scraps and leftover food. However, fine and long vegetable scraps and other fibrous materials often get stuck halfway through the drain hole of the drainer, which can clog the drainer. Not only is this problem easy to occur, but it also requires a lot of effort to remove the stuck item.

The present invention attempts to prevent food waste from getting stuck in the drain hole or clogging it by storing a fine mesh bag inside the drainer.The mesh bag can be installed easily and reliably. In order to achieve this purpose, an elastic spout frame of variable size formed into a ring shape made of an elastic member is used, and the elastic spout is attached to the mouth of the net bag in a reduced diameter state. The opening of the net bag is pressed and fixed to the inner wall surface of the drain port of the washing tank by the elastic restoring force in the direction of diameter expansion of the frame.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings. In FIG. 1, reference numeral 1 denotes a washing tank in a kitchen sink, and a circular drain port 2 is provided at the bottom of the washing tank 1. A cylindrical storage tank 3 is connected below the drain port 2, and a drain pipe 4 is connected to the bottom of the storage tank 3.

The storage tank 3 is formed to have a slightly smaller diameter than the drain port 2, and the inside of the storage tank 3 has a large number of drainage holes 6a.

The cylindrical drainer 5 with the drainer 6b on the side wall and the bottom wall can be attached and detached by locking the flange-like locking edge 5a formed at the upper end of the side wall onto the step 7 at the upper end of the storage tank 3. Attachment: A fine-mesh net bag 8 is replaceably housed inside the drainer 5, and the opening of the net bag 8 is fixed to the inner wall surface of the discharge port 2 by an elastic opening frame 9.

The mesh bag 8 is used to separate and collect garbage from wastewater and prevent it from being caught in the drainage holes 6a and 6b of the drainer 5. As shown in the figure, it is formed by curving an elastic material such as synthetic resin or metal into a ring shape. Both ends of the ring are made to overlap each other as free ends, and the length of the overlap at both ends can be adjusted to increase the size. When installing the net bag 8 using the elastic mouth frame 9, the size of the elastic mouth frame 9 should be made sufficiently smaller than the diameter of the drain port 2. The net bag 8 is held inside the inverted mouth edge 8a in a state in which the diameter is reduced (see FIG. 3), and after the net bag 8 is housed inside the drainer 5, the elastic mouth frame 9 is contracted. When released from the radial state, the elastic mouth frame 9 is elastically deformed in the diametrically expanding direction, thereby fixing the opening of the net bag 8 in pressure contact with the inner wall surface of the drain port 2 as shown in FIG.

In order to ensure the fixation of the net bag 8, a large number of protrusions 10 are provided on the upper edge of the elastic mouth frame 9, and the protrusions 10 are fitted into the net bag 8 so as to be locked therein. In this case, if a notch 11 is provided at the mouth edge of the net bag 8, the net bag can be easily turned over and the elastic mouth frame 9 can be smoothly attached and removed.

The elastic opening frame 9 may be formed by being curved into a ring shape when attaching a straight elastic member to the net bag, but it may also be formed into a ring shape in advance as shown in FIG. ,
In this case, it is necessary to make the size of the drain port larger than the drain port 2.

'In the kitchen sink having the above configuration, the vegetable scraps, leftover food, fibrous materials, and other garbage that have flowed down into the storage tank 3 along with the drainage water are collected by the mesh bag 8, and are collected by the drain hole 6a of the drainer 5.
There is no need to insert and latch onto 6b.

When a certain amount of food waste accumulates in the net bag 8, the elastic mouth frame 9 is removed from the drain port 2, the net bag 8 is taken out, and replaced with a new one.

As detailed above, according to the present invention, a fine-mesh mesh bag is attached to the storage tank equipped with a drainer, so that food waste such as long vegetable scraps and fibrous materials can be removed from the drainer. It is possible to reliably prevent clogging caused by insertion into the extraction hole and latching.In addition, an elastic mouth frame of variable size is attached to the mouth of the mesh bag, and the elastic mouth frame is inserted in the direction of expansion of the diameter of the elastic mouth frame. Since the opening of the net bag is pressed and fixed to the inner wall surface of the drain hole using the elastic force of At the same time, the installation can be carried out reliably regardless of the size of the drain port.
