DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drain trap mounted on a sink, and more particularly to a structure for rotating a dewatering basket housed in a drain trap body. The present invention relates to a drain trap for a dewatering type sink that is configured not to be.

[0002]

2. Description of the Related Art A dewatering basket removably accommodated in a drain trap body of a sink is rotated by a motor mounted below the drain trap body to forcibly remove the moisture of cooking debris contained in the dehydration basket. Dewatering drain traps configured for dewatering are already known.

In these known dewatering type drainage traps, a dehydrating basket contained in the trap body is rotated by a rotating mechanism such as a motor mounted below a casing constituting the trap body, and is included in cooking waste in the basket. The structure is usually such that the water that is removed is forcibly dehydrated by centrifugation.

[0004]

However, the drain trap having the above-mentioned structure only forcibly rotates the lower part of the dehydrating basket, and the upper part of the dehydrating basket is not supported by a special mechanism. Since it was configured as, like the dehydrator in the washing machine, the upper part of the dehydration basket is inevitably rotated while eccentric, and abnormal noise occurs due to the eccentric rotation of the dehydration basket during the dehydration process, or eccentric rotation. As a result, the upper peripheral edge of the dehydrated basket comes into contact with the inner peripheral edge of the trap body, causing wear and damage to both the dehydrated basket and the trap body.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and is intended to cope with the situation. The backside of a water storage lid of a sink is capped at the upper peripheral portion of the dehydration basket to support the dehydration basket, and
It is intended to provide a drain trap for a dehydration-type sink, which is rotatably mounted with a rotation support mechanism that rotates together with a dehydration basket, so that the dehydration basket always rotates accurately and smoothly without eccentricity. .

[0006]

SUMMARY OF THE INVENTION The present invention comprises a drainage trap body, which is composed of a cylindrical body having an open upper end, and rotatably accommodates a dehydration basket therein, and a motor or the like which rotates below the drainage trap body. In addition to mounting the mechanism, a rotating mechanism casing having a rotating shaft for transmitting the rotating force of the rotating mechanism protruding is detachably attached to the upper end, and the rotating shaft is connected to the lower end of the dehydrating basket. In a drainage trap for a sink, a eccentric rotation control lid is attached to the upper end of the dehydration basket, and a bearing is attached to the center of the eccentric rotation control lid, and from the center of the water storage lid attached to the opening of the drain trap body. The main point of the invention is the structure of a drain trap for a dehydration-type sink, which is formed by fitting and integrating a support shaft protruding downward.

The water storage lid 8 is integrated in the through hole 92 formed in the center.
A bearing 93 for fitting the lower end of a bearing shaft 81 projecting downward from the central part of the is tightly fitted.

Numerals 94 and 95 are bearing cases for accommodating the bearing 93 therein and connecting the bearing 93 and the eccentric rotation restricting lid 9 to the upper and lower sides of a through hole 92 formed in the eccentric rotation restricting lid 9. The peripheral portions of the bearing cases 94, 95 fitted from the direction sandwich the peripheral portion of the through hole 92 from above and below to integrate them.

Reference numeral 96 denotes a waterproof cap made of rubber or other material, which is capped on the bearing case 95 to prevent water from entering the bearing 93.

The eccentric rotation control lid 9 is attached to the peripheral edge of the opening of the dehydration basket 2 as shown in the figure, and
It is also possible to configure so that the peripheral edge of the regulation lid 9 is tightly fitted to the inner peripheral edge of the opening of the dehydration basket 2 (not shown).

In the bearing shaft 81, the shaft rod portion projecting from the lower surface of the water storage lid 8 is firmly fitted to the inner cylinder of the bearing 93 to form a washer.
By locking the set screw 98 via 97, the support shaft 81 and the inner cylinder of the bearing 93 are firmly integrated.
