Description

{Filter for sink drainage hole}

More particularly, the present invention relates to a sewing line for a sink drain, and more particularly, to a sewing line for filtering garbage, comprising a top sieve net and a bottom sieve net, and a sieve plate capable of opening and closing between the top sieve net and the bottom sieve net, The present invention relates to a filtering net for a countertop drain so that water contained in the trash can be dehydrated in a lower filtration net and odors generated in food waste can be prevented from being discharged through a drain port.

Generally, kitchens such as homes and restaurants are equipped with sinks for washing dishes or washing fruits and vegetables, which can be used to drain water used for washing dishes, fruits, vegetables, etc. A drain hole is formed.

In this case, there is a drainage line to prevent food waste from discharging to the sewer together with water. In the usual drainage line, the upper part is opened so that water and food waste can be input, and the side and bottom surfaces are filled with food waste And a plurality of holes for drainage are formed on the side surface and the bottom surface.

On the other hand, the food garbage that is caught in the above-mentioned sludge is easily decayed and bad odor is generated or the bacteria are reproduced, so that it is necessary to throw away the food garbage from time to time because there are many problems in hygiene and cleanliness.

However, in the related art, there is inconvenience in disposing the filtered food garbage from time to time. That is, since the conventional filtering net is formed in the shape of a simple barrel, it is seated in the inside of the barrel. Therefore, in order to dispose of the food wastes, there is an inconvenience that the filtering barrel must be lifted from the outer barrel and then shaken to a separate trash container or bag.

In addition, since the food waste extracted by the filter screen contains a considerable amount of water, it is left as it is, or when it is buried in the ground, it easily causes bad odor due to leachate which is spoiled or leaking out, .

In order to solve these problems, Korean Patent Registration No. 10-1418740 discloses a system for collecting food garbage. The main technical feature of the system is that it is installed on the lower side of the sink and connected to the outlet formed in the sink Casing; A garbage container detachably connected to a lower end of the casing and storing food waste introduced into the casing through the discharge port; A filtering vessel installed in the casing so as to be positioned on the upper side of the garbage container and filtering the sewage to be discharged from the food garbage introduced into the inside to the outside; A blocking unit detachably installed between the trash container and the trash container to block wastewater separated from the trash container from entering the trash container; And a drain port formed to penetrate the casing so that the wastewater blocked by the blocking unit is discharged to the outside and connected to the drain pipe or the fitting member for the drain pipe.

That is, the prior art is characterized in that the food waste filtered by the filter box is stored in a waste container connected to the lower end of the casing so that odor does not leak out from the food waste and the waste water does not fall on the floor. In order to store the food waste filtered by the filter container into the trash container, it is necessary to remove the blocking portion while lifting the trash container and then turn the trash container upside down to discharge the food waste to the trash container. There is a disadvantage that the process for storing in the garbage container is too complicated.

In addition, when the food waste filtered by the filter is directly stored in the waste container, the food waste is dropped into the waste container in a state that moisture is contained in the food waste, and the waste container is provided with a separate drainage configuration There is a problem that hygiene problems such as food waste being easily decayed and bacteria are generated in the inside of the trash container are high.

In addition, since the conventional art requires a space for installing a garbage container for storing food garbage separately, it is not applicable to a drain hole of a conventional sink, and a separate space or configuration for separating the garbage container from the sink is additionally provided There is also a problem that it is necessary.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a filtering net for a sink drain according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view showing an embodiment of a filtering net for a sink drain according to the present invention, FIG. 2 is a front elevational view of the present invention shown in FIG. 1, and FIG. 3 (a) Fig. 4 is a plan view showing a filter plate in the present invention shown in Fig. 1, and Figs. 5 (a) and 5 (b) are views showing another embodiment of a filtering net for a sink drain in accordance with the present invention Fig.

In the present invention, a filter screen for filtering garbage is configured by an upper screen and a lower screen, and a filter screen capable of being opened and closed is provided between the upper screen and the lower screen so that water contained in the food waste can be dehydrated from the lower screen 1 is a perspective view of a sewage drainage sewage network according to a first embodiment of the present invention; FIG. 2 is a side view of a sewage drainage sewage network according to a first embodiment of the present invention; A lower screen 20, a filter 30, 30 'and an opening / closing device 40, 40'.

More specifically, the upper sieve 10 is installed in a drain of a sink to filter out food wastes that are dumped together with water. A flange 14 is formed on the upper edge of the upper sieve 10 And can be fixedly installed on the edge of the drain hole.

At this time, the upper portion of the upper sieve 10 has a shape opened to allow food waste and water to be introduced, and a plurality of first water discharging holes 12 (12) for allowing water to pass therethrough and food wastes to be filtered , And the lower portion is closed by the filtering plates 30 and 30 'to be described later so that water and food waste can not pass through.

That is, when the user cleans the bowl or the like in the sink, the water used for washing flows into the drain hole through the plurality of first water discharge holes 12 formed on the side of the upper sieve 10, The food waste is filtered by the first water discharge hole 12 and collected on the upper side of the filter plates 30 and 30 '.

At this time, the side surface of the upper sieve 10 may be inclined with a downward inclination from the upper side to the lower side so that the water passing through the first water discharge hole 12 can be drained more smoothly.

That is, a lower sieve 20, which will be described later, is integrally formed in the lower part of the upper sieve 10. When the side of the upper sieve 10 is formed in a straight shape, the lower sowing mesh 20 narrows the inner space The side of the upper sieve 10 may be formed as an inclined surface so that the diameter of the lower sieve 20 may be smaller so that water drained through the first water outlet 12 So that it can be performed more smoothly.

Needless to say, though not shown, a handle may be provided at the upper end of the upper sieve 10.

Next, the lower sieve 20 is integrally connected to the lower part of the upper sieve 10 and has a closed cylindrical shape. The upper side is closed by the sieve plates 30 and 30 ' It is constructed so that water can not be injected.

In addition, a plurality of second water discharge holes 22 are formed in a lower surface or a lower surface (not shown) of the lower sieve 20 so that the water contained in the food waste contained in the lower sieve 20 can be drained.

More specifically, the lower sieve 20 serves to store the food waste contained in the inner side of the lower sieve 20 so that the food waste can be dewatered. By the operation of the opening and closing devices 40 and 40 ' The food waste located in the upper portion of the filter plates 30 and 30 'is released into the lower side of the lower side 20 and is contained in the lower side of the lower side 20, 2 water discharge hole 22, so that the food garbage can be dewatered in the lower sieve 20.

At this time, as described later, since the food waste is returned to the original position immediately after the food waste is dropped into the lower sifter 20, the injection of water into the lower sifter 20 is blocked, Is cut off by the filter plates 30 and 30 ', so that the emission of odor to the outside can be minimized.

2, it is preferable that the lower sieve 20 is formed so that the lower surface thereof is located inside the side surface, that is, the side surface protrudes to the lower surface of the lower surface, Is prevented from flowing backward to the inside of the lower sieve net (20) through the second water discharge hole (22).

That is, when the lower surface of the lower sieve 20 is formed to have the same height as the lower end of the side surface, water discharged to the outside of the lower sieve 20 through the first water discharge hole 12 of the upper sieve 10 The bottom surface of the lower sieve 20 in which the second water discharge hole 22 is formed can flow backward to the inside of the side surface of the lower sieve 20 through the second water discharge hole 22 in accordance with the structure of the water pipe. It is possible to prevent water from flowing backward into the lower sieve net 20.

Meanwhile, the lower sieve 20 may be divided into a first body 20a and a second body 20b, which is accommodated in the lower sieve 20 to facilitate the discharge of the dehydrated food waste In order to make it possible.

In more detail, the first body 20a is integrally connected to the lower portion of the upper sieve 10, and has a cylindrical shape with its side surface closed and the lower surface thereof opened. The upper surface of the sieve body 30 ').

The second body 20b is detachably coupled to the lower portion of the first body 20a and is formed in the same cylindrical shape as the first body 20a and has a second water discharge hole 22 are formed.

At this time, a female screw 24 is formed on the inner peripheral surface of the lower end of the first body 20a and a male screw 26 is formed on the outer peripheral surface of the upper end of the second body 20b so that the first body 20a and the second body 20b can be detachably coupled by screwing.

That is, since the lower sieve 20 including the first body 20a and the second body 20b is integrally connected to the upper sieve 10, the upper sieve 10 is drawn out from the drain, When the first body 20a and the second body 20b which are threadedly coupled to each other are separated from each other while the lower sieve 20 is pulled out as described above, the second body 20b It is possible to treat the food waste contained in the food waste.

At this time, the food waste is discharged in a state of being dehydrated by natural drainage through the second water discharge hole (22) in the lower sifter (20), so that sanitation problems such as the sewage flow generated when discharging the food waste can be solved do.

When the volume of the second body 20b is small, the food waste contained in the lower sieve 20 may overflow when the first body 20a and the second body 20b are separated from each other. It is preferable that the second body 20b is formed to have a relatively large volume as compared with the first body 20a.

The screen 30 is horizontally disposed between the upper screen 10 and the lower screen 20 so as to divide the upper screen 10 and the lower screen 20, So that water is prevented from being introduced into the lower sifter 20 from the upper sifter 10 by blocking the lower part of the upper sifter 10 and the upper part of the lower sifter 20, And serves to prevent the odor generated from the food waste contained therein from being leaked to the outside.

In this case, since the filter plate 30 is opened to both sides, the food waste placed on the filter plate 30 can not be separated from the food waste, There is an advantage that the water can be dispersed into the lower side of the sieve 20 without being biased to one side.

More specifically, as shown in FIG. 4, the filter plate 30 includes a fixed shaft 32, first and second filter plates 30a and 30b, first and second torsion springs 34a and 34b, The fixed shaft 32 is fixed horizontally at the center of the connection between the upper sieve 10 and the lower sieve 20 to support the sieve 30, (Not shown) in which the fixing shaft 32 is inserted is formed at the connection portion between the screen 10 and the lower screen 20.

Next, the first and second filter plates 30a and 30b are semicircular plates hinged to the fixed shaft 32, and have the same inner diameters as the lower end of the upper sieve 10 and the upper end of the lower sieve 20, And is configured to be able to block the gap between the upper sieve 10 and the lower sieve 20 and to be pivoted downward about the fixed shaft 32 by the operation of the opening and closing device 40 .

The first and second torsion springs 34a and 34b are respectively inserted into the connecting portions between the first and second filter plates 30a and 30b and the fixed shaft 32, So that the second filtering plates 30a and 30b can maintain a state in which the upper sieve 10 and the lower sieve 20 are blocked.

That is, the first and second torsion springs 34a and 34b have an initial torsion for rotating the first and second filter plates 30a and 30b in a direction to seal the lower portion of the upper sieve 10, The first and second filter plates 30a and 30b are inserted into the hinge coupling portions between the first and second filter plates 30a and 30b and the fixed shaft 32 so that the first filter plate 30a and the second filter plate 30b are positioned below the upper filter plate 10 When the first and second filter plates 30a and 30b are opened by the operation of the opening and closing device 40 to be described later, the first and second filter plates 30a and 30b So that the lower part of the upper sieve 10 can be closed.

At this time, the first and second filter plates 30a and 30b are limited to be rotated in the direction of the upper screen 10, that is, the upper portion of the fixed axis 32 by a packing member 50 to be described later, (Not shown) protruding to the inside of the lower edge of the upper sieve 10 in order to restrict the upward rotation of the first and second filter plates 30a and 30b.

When the end portions of the first and second filtering plates 30a and 30b are rotated downward as described above, the connection between the upper and lower filtering nets 10 and 20 is opened, The food garbage can be lowered along the inclined surface formed by the first and second filter plates 30a and 30b and can be introduced into the lower sieve 20.

When the user places the driving shaft 42 after the food waste located in the upper portion of the filter plate 30 is put into the lower sieve 20 and then the user puts the driving shaft 42 into the torsion springs 34a and 34b, The first and second filter plates 30a and 30b are returned to their original positions to maintain a state in which the space between the upper sieve 10 and the lower sieve 20 is blocked.

At this time, the extended portion 46 may be hinged to the upper end of the drive shaft 42. The extended portion 46 serves to allow the first and second filter plates 30a and 30b to be opened more .

3 (b), as the user moves the drive shaft 42 downward a large amount, the opening width of the first and second filter plates 30a and 30b becomes larger. The upper end of the drive shaft 42 may protrude from the upper portion of the upper sieve 10 to cover the cover 60 for closing the drain hole. The upper end of the drive shaft 42 is protruded to the upper portion of the upper sieve 10 by forming the extended portion 46 to be hinged so that the extended portion 46 can be bent at a vertical or more angle with the drive shaft 42 .

In the above description, the first and second filter plates 30a and 30b are opened by using the opening and closing device 40. Alternatively, the user may operate the first and second filter plates 30a and 30b without using the separate opening / And / or the first and / or the second filter plates 30a and 30b may be selectively opened by pressing the ends of the second filter plates 30a and 30b downward.
