DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kitchen sink, and more particularly to a trash receiving tray for collecting trash in drainage and a drainage structure of the sink provided with the tray.

[0002]

2. Description of the Related Art Sinks to be incorporated into kitchen sinks are generally tubs having an appropriate depth.
Drainage holes are provided at the bottom and connected to drainage pipes on the building side.

[0003] The drain port is almost always located at the center or one side of the sink without presenting, for example, Japanese Utility Model Laid-Open Nos. 4-12771 and 4-134576. The bottom has a slope so that water flows toward this drain port side.

A drain plate is provided with a tray for catching fine dust, and a tray for catching fine dust is installed below the eyelet for collecting large dust.

[0005] In such a sink provided with a perforated plate and a tray at the entrance of a drainage channel, washing is often performed with dust and the like remaining on the perforated plate and the tray. The accumulated dust is usually removed when washing is completed or when cleaning around the kitchen. Therefore, the waste water during washing and the like passes through the accumulated dust before flowing to the drain passage, and the waste water further contains the dust and is further polluted.

In order to solve such a problem, for example, as described in Japanese Utility Model Application Laid-Open No. 6-1474, a drainage device for connecting a drainage pipe on a building side to a sink is provided with a drainage port and a trash container. Are provided at positions shifted from each other. This is provided with a lid that covers the drain port and the garbage storage container and that can open only one of these sides so as to be movable along the bottom surface of the sink.

[0007]

If such a lid is provided, the garbage can be collected by opening the garbage container side when garbage is discharged, and the garbage can be collected when only the effluent is drained. By opening the mouth side, water can flow without passing through the trash container.

[0008] However, in the washing operation, there are various cases in which garbage is included or not, and the operation of moving the lid so as to switch to either garbage collection or drainage is quite troublesome.

[0009] Further, since it is uncertain whether garbage comes out or not at the time of washing, unexpected garbage may flow out, for example, when the lid is set to open the drain port side. It is not perfect for collecting garbage.

As described above, although it is preferable to attempt to collect garbage and prevent wastewater from passing through unnecessary garbage, there are many points to be improved from the viewpoint of practical usability.

The problem to be solved in the present invention is to make it possible to collect garbage and to use the wastewater without unnecessary contamination without any trouble in washing work in a sink or the like. .

[0012]

[0015]

[0016]

According to the present invention, the combination of the inclined surface on which the meshes or the small holes are arranged and the bottom surface thereof allows the drainage from the surface of the sink to flow into the inclined surface when incorporated into the drain of the sink. The meshes or small holes included in the inclined surface can be used as a drainage passage, and the collected trash is accumulated on the bottom side by its own weight or by extrusion by the falling drainage. Therefore, during the drainage period,
The wastewater having an inclined surface as a water-permeable surface flows away while avoiding contact with dust accumulated on the bottom side, thereby preventing wastewater from being contaminated by passing through the dust.

By promoting the accumulation of dirt on the bottom side and making the inclined surface a drainage water passage surface, it is possible to similarly prevent the contamination of the wastewater by various shapes and arrangements of the inclined surfaces. .

Further, if the inclined surface of the tray is oriented toward the center of the sink when incorporated into the drain of the sink,
The water flow surface can be adjusted so that the drainage flows in.

In the case where the drain port is located on the back side of the sink, if the front surface or the side facing the left and right of the sink is set as an inclined surface, the drain is deposited on the bottom side even when the drain water flows in from three sides. Drainage without contact with garbage is possible.

[0020]

FIG. 1 is a schematic perspective view of a sink provided with a tray for receiving waste water according to the present invention. In the figure, a sink 1 is placed on a counter 51 attached to the upper end of a cabinet 50.
Has been fixed. The sink 1 is made of, for example, a stainless steel plate, and is of an under-counter type in which a rim 1a formed around the upper end of the sink 1 abuts against the lower surface of the counter 1 and is fixed by a holder.

A sub-counter 1b slightly lower than the rim 1a is formed on the left and right sides of the sink 1 except for the center part in the frontage direction, and a faucet 2 is provided on the left sub-counter 1b while The sub-counter 1b has a recessed pocket 1c for accommodating a container such as a detergent. Then, a drainage opening 1d for connecting the drainage device 3 is opened from the bottom of the sink 1 sandwiched between these sub-counters 1b to the rising wall at the back.

As shown in the plan view of the sink 1 in FIG. 2, the drainage opening 1d has a square planar opening cross section, and has a shape protruding forward from the back wall of the sink 1. The vertical section of the opening edge has a shape in which the letter L is turned 90 ° counterclockwise.

FIG. 3 is a vertical sectional side view showing a main part of the drainage device 3 and the sink 1, FIG. 4 is a partially cutaway front view of the drainage device 3, and FIG.

The drainage device 3 includes a drainage trap 4 having a lower end connected to a drainage pipe (not shown) provided in the cabinet 50 and connected to a drainage channel on the building side, a drainage tank 5 joined to the upper end thereof, and a drainage tank 5 connected to the drainage trap 5. The tray 6 is provided with a trash receiving tray 6 which can be taken in and out of the water tank 5.

The drainage trap 4 has a drainage cylinder 4a set up inside and a surrounding area covered with a cover 4b, similarly to those used for sealing water in various drainage devices. When the drain trap 4 and the drain tank 5 are sealed by the connector 7, they are integrally connected at that time.

The drain tank 5 is formed with a male screw 5b around its periphery as a cylindrical connection part 5a for screwing the lower end of the drain tank to the connector 7, and a drain tray 6 for receiving waste dust can be dropped at the upper end. This is a square opening cross section. The upper end side of the drainage tank 5 has a vertical cross-sectional shape that changes the direction of the opening from the core of the connecting portion 5a toward the front obliquely upward, and the upper end portion has a flange portion 5 for joining to the outer peripheral surface of the sink 1.
c is provided.

As shown in the exploded perspective view of FIG. 6, the flange portion 5c has a flat flange 5d which abuts against the bottom surface of the sink 1.
And a rising flange 5e, which abuts against the peripheral surface of the rising wall of the sink 1, is integrally formed. That is, the flat flange 5d and the rising flange 5e have such a width that the inside and outside of the opening edge of the drain opening 1d of the sink 1 can be bordered, and have a shape that fits the profiles of the bottom surface of the sink 1 and the rising wall. It is what it was. As is apparent from FIG. 3, the rising flange 5e is positioned so as to straddle the opening cross section of the drainage tank 5 at the level of the flat flange 5d in the width direction. The end on the side is incorporated on the back side with respect to the rising flange 5e.

As shown in FIG. 6, the tray 6 is formed in a flat tub shape using a frame 6a using a metal plate as a frame, and a net 6b using, for example, punching metal or the like on the bottom and peripheral surfaces of the frame 6a. Is pasted. The outer periphery of the rim 6c at the upper end, which constitutes a part of the frame 6a, has a shape that can exactly fit into the inner peripheral wall of the drainage tank 5 when the tray 6 is set. Also,
On the bottom surface of the lower frame 6a, two cushions 6d are provided at both ends in the width direction. These cushions 6d are placed on mounting portions 5f formed in steps on the inner wall in the width direction of the drainage tank 5, and at this time, are held in the state of FIG.

When the tray 6 is set in the drain tank 5, only the net 6b facing the front side is a surface inclined forward, and this portion is used as a water passing surface 6e. The flat bottom portion on the back side of the water passage surface 6e is made to function as a dust collecting surface 6f, and the front frame 6a is located on the tray 6 so that the tray can be easily taken out when collecting the collected dust. A knob projection 6a-1 is provided on the surface facing the inside.

In the above configuration, the drainage water when washing with the sink 1 flows out to the drainage device 3 from the drainage opening 1d located on the back side of the sink 1. Then, the garbage contained in the wastewater gradually accumulates on the collection surface 6f side, and the wastewater is drained so as to pass through the water passage surface 6e as it is.

FIG. 7 is a schematic diagram for explaining such wastewater and dust collection.

As shown in FIGS. 1 and 2, the drainage device 3 is located at the back of the sink 1, so that the drainage flowing along the bottom surface of the sink 1 in the washing operation is located in front of the drainage device 3. What flows in from the side is the largest in quantity. Then, as long as the inside of the sink 1 does not accumulate due to the drainage, the flow of the drainage along the bottom surface of the sink 1 flows from the front end side of the tray 6 toward the water passage surface 6e as shown in FIG. .

By allowing the drainage to pass through the portion A in the region of the inclined water passage surface 6e, the water passage surface 6e
The garbage gradually accumulates on the net 6b that forms. The debris slides down to the area B on the collection surface 6f side depending on the amount of the debris and its own weight, and is also pushed out to the collection surface 6f side by the force of the drainage flowing from the sink 1. Therefore, after a lapse of time from the start of drainage, dust in the drainage gradually accumulates on the collection surface 6f side, and drainage without dust on the water passage surface 6e becomes possible.

According to such a drainage form, most of the water discharged during the washing operation does not flow through the water passage surface 6e and reaches the collection surface 6f side, and flows to the drainage pipe to the building side. Is not contaminated by the waste collected by the tray 6. Therefore, unlike the conventional example, the operation of moving the lid when dust is likely to occur is not necessary, and not only is the usability improved, but also the operation is improved.
Good garbage collection and prevention of wastewater pollution can be achieved regardless of whether or not garbage is generated.

FIG. 8 is an example showing the outline of another tray 6.

In this example, not only the net 6b on the front surface of the tray 6 but also the water surface 6e is formed, and the nets 6b on the left and right sides thereof are also formed as inclined water surfaces 6g. Then, the tray 6 having the three water passage surfaces 6e and 6g is installed in the drain tank 5 in the same orientation as the posture shown in FIG. 3, so that dust can be collected from the water passage surface 6g even for drainage flowing from the left and right. It can slide down on the collecting surface 6f. Therefore, similarly to the previous example, for drainage passing through the water passage surfaces 6e and 6g,
Collection of garbage and sliding down to the collection surface 6f are performed,
The degree to which the wastewater passes through the garbage deposited on the collection surface 6f can be reduced, and the pollution of the wastewater can be prevented.

FIG. 9 is a schematic view showing still another example of the tray.

In this example, the tray 8 has a circular planar shape, and large-diameter and small-diameter annular frames 8a and 8b are arranged at the upper and lower ends in an eccentric relationship with each other, and a space between these frames 8a and 8b is provided. Net 8c on peripheral surface and bottom surface
It is the one with Due to the relationship between the large diameter and the small diameter of the frames 8a and 8b, the peripheral net 8c becomes a mortar-shaped inclined surface whose size is reduced downward, and the inclination angle varies in the circumferential direction due to the eccentric relationship.

By using the configuration having such an inclined surface, the peripheral surface of the net 8c can be used as the water-permeable surface 8d, and the net 8c located at the bottom can be used as the collecting surface 8e. FIG. 10 is a schematic view showing an example in which the tray 8 of FIG.

As shown in FIG. 2C, the gentlest slope of the water passage surface 8d is arranged so as to face the front side of the sink 1. As a result, similarly to the case shown in the previous example, the garbage in the drainage is accumulated on the collection surface 8e due to the sliding down of the garbage from the water passage surface 8d or the flushing by the flow of the wastewater, and the wastewater flows through the water passage surface 8d. Runs off while avoiding contact with garbage.

FIG. 11 is a schematic view showing still another example of a tray and its incorporation into a sink.

In this example, the tray 9 has a cylindrical shape having an annular frame 9a at its upper end and a net 9b at its lower end, and has a shape whose axis is obliquely inclined. In the case of the one having such an inclined axis, if it is installed in the drainage tank 5 as shown in FIG. 3B, the net 9b of the front half of the peripheral wall is used as the water-passing surface 9c and the flat bottom net is used. The portion 9b can be used as the collecting surface 9d.

Also in this example, the inclination of the water passage surface 9c and the collection surface 9d disposed on the back side of the water passage surface 9c prevent the dust in the drainage from being trapped on the collection surface 9d and avoiding contact with the collected dust. Wastewater flow is possible.

[0044]

According to the drainage dust receiving tray provided in the sink according to the present invention, the bottom side is formed as a collecting surface for accumulating dust and the inclined surface is drained by the inclination of a part of the peripheral surface on which the meshes or small holes are arranged. The flow of garbage due to the flow of water can make the water flow surface that can always pass water. Therefore, it is possible to reliably collect garbage and quickly drain the garbage without requiring any means or handling for switching the operation to drainage or garbage collection, thereby preventing contamination of the effluent with garbage.

[0045] Thus, according to the invention, the waste water waste receiving sink with a tray, by the proper positional relationship between the inclined surface of the position and the tray of the discharge port, it is possible to waste water contamination is small by garbage .
