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.

[0003] In these known dewatering type drain traps, the dewatering basket accommodated in the trap body is rotated by a rotating mechanism such as a motor mounted below a housing constituting the trap body, and is included in cooking debris in the basket. It is common to adopt a structure in which water is forcibly dehydrated.

[0004]

However, in the known drain trap having the above structure, the lower part of the dewatering basket is forcibly rotated, and the upper part of the dewatering basket is configured as a free end. Similarly to the above, it is inevitable that the upper part of the dewatering basket rotates while being eccentric. There is a drawback that both the dewatering basket and the trap body are damaged by touching the inner peripheral portion.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has been made in response to the above circumstances. Accordingly, an object of the present invention is to provide a drainage trap for a dewatering type sink configured to always perform accurate and smooth rotation without the dewatering basket being eccentric.

[0006]

SUMMARY OF THE INVENTION The present invention consists of a cylindrical body having an open upper end and a rotatable basket inside which a dewatering basket is rotatably accommodated, and a rotating motor such as a motor below the drain trap body. A mechanism is mounted, and a rotating mechanism housing having a rotating shaft for transmitting the rotating force of the rotating mechanism protrudingly attached to an upper end thereof is detachably attached, and the rotating shaft is connected to a lower end of the dewatering basket. In the drain trap for the type sink, the eccentric rotation regulating lid is attached to the upper end of the dewatering basket, and the bearing attached to the center of the eccentric rotation regulating lid is attached to the center of the outer lid attached to the opening of the drain trap body. The gist of the invention is a structure of a drain trap for a dewatering type sink in which a bearing shaft protruding downward is fitted and integrated.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

A drain trap for a sink according to the present invention comprises a cylindrical casing, and a drain trap body 1 in which a dewatering basket 2 is rotatably accommodated, and is detachably attached below the drain trap body 1. A rotating mechanism that houses a motor housing 4 having a rotating mechanism 3 such as a motor mounted therein, and protrudes a rotating shaft 5 that transmits the rotating force of the rotating mechanism 3 to the dewatering basket 2 at the upper part of the housing. And the housing 6.

The drain trap cylinder 1 is formed in a cylindrical shape having an open upper end, and a drain port 11 is formed on the side of the lower end.
Are formed. A flange 12 is formed on the outer periphery of the upper end of the drain trap body 1, and a fitting hole formed in the sink 14 by flowing the flange 12 through a fastening ring 13.
It is attached to 15.

Reference numeral 7 denotes a water storage lid which is detachably fitted to the opening of the drain trap body 1, and is a known water storage lid used for storing water in the sink 14 of the sink.

Reference numeral 8 denotes an eccentric rotation restricting lid which is detachably attached to the upper end opening of the dewatering basket 2 and has a flange 81 bent downward at the peripheral edge thereof to cover the opening peripheral edge of the dewatering basket 2. And integrated with the concave part 82 formed in the center.
, A bearing 83 for fitting a bearing shaft 91 projecting downward from the center of the outer lid 9 is closely fitted.

The eccentric rotation restricting lid 8 is not limited to being attached to the peripheral edge of the opening of the dewatering basket 2 as shown in the figure.
The peripheral edge of the regulating lid 8 may be closely fitted to the inner peripheral edge of the opening of the dewatering basket 2.

The upper portion of the support shaft 91 is configured to protrude above the outer lid 9 so as to be able to double as a knob. (See FIGS. 2 and 3)

The outer lid 9 is interposed between the water storage lid 7 and the eccentric rotation restricting lid 8. The outer lid 9 is fitted to the inner peripheral edge of the opening of the drain trap body 1, A support shaft 91 is attached to the portion so as to protrude downward.

The support shaft 91 has a shaft rod portion projecting below the outer lid 9 firmly fitted to the inner cylinder of the bearing 83, and a washer 92.
The support shaft 91 and the inner cylinder of the bearing 83 are firmly integrated by locking the set screw 93 through the shaft.

The washer 92 is located at an intermediate portion between the inside of the concave portion 82 formed at the center of the eccentric rotation restricting lid and the bearing 83, and its peripheral portion is provided only on the lower surface of the inner cylinder of the bearing 83. It is formed as a size that touches. (FIG. 3
reference)

The set screw 93 has a screw diameter smaller than the outer diameter of a through hole 84 formed at the center of the eccentric rotation restricting lid 8 so as not to hinder the outer cylinder of the bearing 83 from rotating. doing. (See FIGS. 2 and 3)

The outer lid 9 and the eccentric rotation restricting lid 8 are always used by being attached to the drain trap body 1. The respective lids 8 and 9 have through holes 93 through which cooking debris flows and falls. Many 93 and 85 ... 85 are drilled. (See FIGS. 4 and 5)

Reference numeral 86 denotes a coupler for receiving rotation formed on the lower surface of the dehydrating basket 8. The rotation transmitting coupler 51 attached to the rotating shaft 5 is detachably fitted to the rotating mechanism 3 to rotate.
It is configured to effectively transmit the rotational force.

The motor housing 4 includes a motor 41,
Transformer 42, balance weight 43, etc. are stored,
The rotation force of the motor 41 is transmitted to the rotation shaft 5 via the reduction mechanism 44.

The structure of the rotation mechanism 3 and the structure of the rotation receiving coupler 86 formed at the lower end of the dewatering basket 2 and the structure of the rotation transmitting coupler 51 mounted at the upper end of the rotary shaft 5 are important for the present invention. Therefore, the detailed description of the structure is omitted.

[0022]

The effects of the present invention configured as described above are as follows.

(1) Since the eccentric rotation restricting lid 8 is detachably mounted on the upper end opening of the dewatering basket 2, when the dewatering basket 2 is rotated for dewatering, the upper part of the dewatering basket 2 is eccentrically rotated. It is possible to accurately regulate what is done, and to completely solve various disadvantages of the conventional dewatering basket.

(2) Since the dewatering basket 2 does not rotate eccentrically, abnormal noise generated at the time of eccentric rotation can be prevented. There is an excellent feature that can accurately avoid damage and the like caused by contact with the part.

(3) A bearing shaft 91 attached to the center of the outer lid 9 so as to protrude downward is firmly integrated with the inner cylinder of the bearing 83 attached to the center of the eccentric rotation restricting lid 8, Since the outer cylinder of the bearing 83 is configured to rotate freely, even if the outer lid 9 is fixed to the upper end of the opening of the drain trap main body 1, the rotation can be performed accurately without obstructing the rotation of the dewatering basket 2.
