Description

  The present invention relates to a structure of a drain of a glass sink.

Conventional sinks are mainly made of synthetic resin, stainless steel, ceramics, etc., but in recent years, demand for glass sinks has grown rapidly, and this has made them suitable for glass sinks. Peripheral devices are being developed.

  In general, glass molded products are made by bending, cutting and pasting while melting the glass plate with heat, and finishing to the desired shape. As shown in FIG. 5, it is necessary to attach the flange 23 of the sink trap 21 that protrudes into the drainage port R from above, as shown in FIG. I didn't get it. As a result, the living water W does not flow into the drainage channels S and 25 below the water level corresponding to the thickness of the flange 23 and the sealing material 22, and remains at the bottom of the sink forever, resulting in an unsanitary state around the sink. There was an inconvenience.

  An object of the present invention is to provide a drainage structure for a glass sink that reliably drains water and enables hygienic use.

  The present invention provides a sink provided with a flange that allows a cylindrical body having a drainage channel to enter the drainage port from above the sink bottom plate and that can be locked to the peripheral edge of the drainage port at the upper edge of the peripheral wall of the cylindrical body The trap, the sealing material interposed between the lower end surface of the flange and the upper surface of the sink bottom plate, and the cylinder projecting downward from the drain port are connected, and the sink bottom plate is sandwiched between the flange and the sealing material And a drainage trap having a cylindrical shape that can communicate with the drainage channel when connected, and at least one portion of the sealing material is provided with a notch, and the peripheral wall of the cylinder is further provided with the notch It is characterized in that a hole that communicates with the drainage channel is provided at a location that can communicate with the drainage channel.

  Here, the sealing material may be any material that is in close contact with the upper surface of the sink bottom plate and maintains water tightness, but since the sink is made of glass, an elastic material such as synthetic rubber or silicon that does not easily damage the sink surface is used. It is desirable to apply. Further, the shape of the notch is not specified as long as it communicates with the drain outlet side through the sealing material. For example, a part of the sealing material is divided or the thickness of the sealing material is reduced. The part may be cut into a tunnel shape. Furthermore, the diameter of the hole and the shape of the hole are not particularly limited as long as the water fed from the notch is poured into the drainage channel in the sink trap.

  When formed in this way, the living water accumulated in the flange portion of the sink trap and the thickness portion of the seal material, which is normally lifted from the upper surface of the sink bottom plate, passes through the gap formed between the cut portion of the seal material and the upper surface of the sink bottom plate. Furthermore, since it flows through the hole provided in the peripheral wall of the cylindrical body of the sink trap, it becomes a structure that can reliably guide the domestic water used in the glass sink to the drainage channel.

  According to this invention, even if it is a glass sink which cannot perform a face-to-face process, the domestic water in a sink can be drained reliably, and from this, a sink can be used hygienically.

  Next, an embodiment of a glass sink drain structure according to the present invention will be described below with reference to the drawings.

Each member of this drain outlet structure is demonstrated based on FIG.
Reference numerals 1 and 10 are sink traps. The sink traps 1 and 10 have a shape in which a flange 10 is projected over the entire upper edge of the cylindrical body 1 having the drainage channel S, and an opening is formed in the bottom plate 8 of the sink. The cylindrical body 1 is inserted into the drainage port R from above, and the flange 10 is locked to the peripheral edge of the drainage port R so that the sink traps 1 and 10 cannot be detached from the sink bottom plate 8. It keeps in. Reference numeral 2 denotes a sealing material. As shown in FIG. 2, the sealing material 2 is an elastic ring-shaped member made of synthetic rubber. The sealing material 2 is interposed between the lower end surface of the flange 10 and the upper surface of the sink bottom plate 8, and ensures the watertightness between the members 8 and 10 and the protection state of the sink surface. Reference numeral 3 denotes a drain trap, and the drain trap 3 has a cylindrical shape having a drainage channel S, similar to the sink traps 1 and 10. In this case, the sink bottom plate 8 can be clamped from above and below. Reference numeral 4 denotes an adjuster between the drain trap 3 and the bottom surface of the sink bottom plate 8. This adjuster 4 is made of soft synthetic rubber in order to improve the water tightness with the sink bottom plate 8, similar to the sealing material 2 described above. It is formed.
Reference numeral 12 denotes a groove formed with the water distribution pipe 9.

  Reference numeral 5 denotes a countersink that prevents dust, hair, etc. from flowing directly into the drainage channel. In the insertion tube portion of the eyeglass plug, drain holes 13 are provided at a plurality of locations on the peripheral wall, and water flowing into the sink is smoothly drained from the drain holes 13 while dust and hair are between the drain holes 13. Therefore, the eyepiece stopper 5 can be periodically removed from the drainage channel S of the sink trap cylinder 1 and cleaned.

  Next, the drainage procedure of the notch 7a provided in the sealing material 2 which is the main part of the present invention and the hole 6 provided in the cylindrical body 1 will be described with reference to FIG.

  The sealing material 2 interposed between the sink trap flange 10 and the sink bottom plate 8 is in a state of being lifted from the upper surface of the sink bottom plate 8 so that the water flowing into the sink first floats as described above. It gathers in the place which provided the two notches 7a. Then, the water that has passed through the notch 7a flows down to the upper side of the tapered surface of the drain trap 3 and the lower end of the slope communicates with the hole 6 so that the water passes through the hole 6 and enters the inside of the cylinder 1. Even in the case of a glass sink that flows toward the drainage channel S and does not normally have an embedded stepped portion for the flange 10 around the drainage port R, the bottom of the sink does not collect water.

  FIG. 4 shows another embodiment of the present invention, in which the shape of the notch 7b of the sealing material 2 is formed in a groove shape in which only the lower side is curled. Even in the case of this notch 7b, the water in the sink that tends to accumulate in the thickness portion of the sealing material 2 and the flange 10 can be smoothly drained from the notch 7b without providing a flange for the flange 10 as in the above-described embodiment. And the sink can be used hygienically.

It is the longitudinal cross-sectional view which notched one part explaining the drain outlet structure of the glass sink of this invention. FIG. 2 is a cross-sectional view taken along line AA in FIG. 1. FIG. 2 is an enlarged longitudinal sectional view showing B in FIG. 1 in an enlarged manner. It is the longitudinal cross-sectional view which expanded a part which shows other embodiment of this invention. It is the longitudinal cross-sectional view which notched some explaining the drain outlet structure of the conventional glass sink.
