Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage trap to be attached to a sink, and more particularly to a drainage trap for a dehydration type sink configured so that cooking waste contained in a dehydration basket can be safely centrifugally dehydrated. .

[0002]

2. Description of the Prior Art A trap for drainage attached to a sink is
The dehydrated basket is detachably accommodated in the cylindrical drain housing fixed to the sink, and cooking waste (raw garbage) generated on the sink is stored together with water in the dehydrated basket, and then only water is removed from the dehydrated basket. It is generally configured.

However, the above-mentioned drain trap has a structure in which the water contained in the cooking waste (raw refuse) contained in the dehydration basket is not forcibly dehydrated, and only the surface-adhered water is dehydrated. The water contained in the cooking waste is discarded without being dehydrated.

For this reason, there is a drawback that a large amount of heat energy is required when incinerating the cooking waste in a public incinerator, and the incineration cost rises, and in addition, the incinerator is exposed to high heat for a long time, which results in a short time. There was a drawback that the incineration facility was exhausted.

[0005]

In order to solve such a drawback, an electric motor is installed in a drainage casing, and the dehydrated basket is rotated by the electric motor to forcibly centrifuge the cooking waste contained in the dehydrated basket. Although the one configured to be dehydrated has been proposed, in the known centrifugal dehydration structure, since the motor is directly attached to the lower surface of the dehydration basket, the dehydrated water wets the motor and causes an electric leakage accident. The danger was pointed out.

Although a waterproof structure of the motor has been proposed, there is a drawback that the motor removal work at the time of maintenance is complicated because the motor mechanism is mounted in the drain housing.

Further, in the above-mentioned known structure, a switch for rotating the motor is separately provided on the sink or the like,
Since it was necessary to operate the switch when performing the dehydration operation, it has been pointed out that there is a danger of an electric shock accident or the like caused by operating the switch with a hand wet with water.

[0008]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has a structure in which an upper drainage cylinder and a lower drainage cylinder having a motor housing and a deodorant mechanism are separated from each other, and The motor housing housed within the drainage cylinder is intended to provide a drainage trap for a dehydration-type sink with a completely waterproof structure.

Another object of the present invention is to provide a structure in which the upper drainage cylinder, the motor housing and the lower drainage cylinder can be separated from each other, so that the drainage trap mechanism as a whole can be easily separated and is excellent in maintainability. It is intended to provide a drain trap for sinks.

[0010]

SUMMARY OF THE INVENTION The present invention is composed of a cylindrical body having open upper and lower ends, and an upper drainage cylinder in which a dehydration basket is rotatably accommodated inside and a lower portion which is detachably locked below the upper drainage cylinder. It is composed of a combination of a drainage cylinder and a motor housing detachably attached to the inside of the lower drainage cylinder, and the rotation shaft of the motor mounted in the motor housing is projected above the motor housing, and a coupler mechanism is provided at the protruding tip. The essential point of the invention is the structure of a drain trap for a sink, which is formed by attaching the coupler mechanism to the coupler mechanism detachably fitted to the lower surface of the dehydration basket.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. The drainage trap for a sink according to the present invention is composed of a cylindrical casing and has an upper drainage cylinder 1 rotatably accommodating a dehydration basket 2 therein, and is detachably connected to a lower end portion of the upper drainage cylinder 1. By the lower drainage cylinder 3 having a deodorizing function and the motor housing 5 which is detachably fitted inside the lower drainage cylinder 3 and accommodates the motor 4 inside, and the rotating shaft 41 is projected at the upper end. I am configuring.

The upper drain cylinder 1 is formed in a cylindrical shape with both upper and lower ends opened, and a flange portion 11 on the outer periphery of the upper end is attached to a fitting hole formed in the sink sink 6 via a tightening ring 12. .

A tightening ring 12 formed on the flange portion 11 of the upper drainage cylinder 1 and a rubber lid 13 fitted in the opening of the upper drainage cylinder 1 (a large number of radial notches are formed toward the center). However, the structure of the closing lid 7 (reservoir lid) that is detachably fitted above the rubber lid 13 to prevent the water in the sink 6 from flowing into the upper drainage cylinder 1 is for known drainage. Since the structure is the same as that formed in the opening of the trap, detailed description thereof will be omitted.

Numeral 14 is a switch for driving a motor formed by using a hall element, which is buried near the upper end flange portion 11 of the upper drainage cylinder 1.

The motor drive switch 14 comprising a Hall element drives the sensor 15 formed in the Hall element by the magnetic force of the magnet 71 attached to the peripheral portion of the closing lid 7 to perform a switching operation.

When the switch 14 for driving the motor is driven, the switch display 16 displayed above the position where the drive switch 14 is embedded, and the switch display displayed above the closing lid 7 to which the magnet 71 is attached. If 72 is matched, the switch is automatically input. (See Figure 3)

An electric wire (not shown) drawn out from the Hall element constituting the motor drive switch 14 is guided in a watertight manner into the motor housing 5 through a power supply wiring port 31 formed in the peripheral body portion of the lower drainage cylinder 3. .

Reference numeral 17 ... 17 is a water flow-down guide plate projecting from the inside of the upper drainage cylinder at an appropriate interval. When the dehydration basket 2 is rotated, the water centrifugally dehydrated from the cooking waste is the upper drainage cylinder. After colliding with the inner wall of No. 1, it is prevented from rising and scattering in the direction of the closing lid 7, and is guided so as to always flow downward.

The above-mentioned water flow-down guide plates 17 ... 17 do not vertically project on the inner wall of the upper drainage cylinder 1, but should be gradually inclined from the upper part to the lower part (from the upper part to the lower part). It is desirable to tilt it about 15 degrees).

The lower drainage cylinder 3 and the upper drainage cylinder 1 are connected to each other by fitting the upper end of the lower drainage cylinder 3 to the outer periphery of the lower end of the upper drainage cylinder 1 and then tightening the screws 32 ... 32. Screw it on. (See Figure 4)

The lower drain cylinder 3 is formed in a cylindrical shape having an outer diameter substantially the same as that of the upper drain cylinder body 1, and a drain cylinder 33 having a small outer diameter is formed at the lower end.

The upper end of the drainage tube 33 is protruded to the inside of the lower drainage tube 3 by an appropriate height to form a trap inner cylinder 34. The outer circumference of the upper end of the trap inner cylinder 34 is separated from the lower end of the motor housing 5. A cylindrical deodorizing trap having a siphon mechanism is formed by covering the protruding cylindrical trap outer cylinder 51 with a predetermined gap.

The motor housing 5 includes the lower drainage cylinder 3
After being removably fitted inside, the appropriate portion of the outer peripheral portion is screwed to the lower drainage cylinder 3.

The outer peripheral portion of the motor housing 5 and
Several drainage holes 35 ... 35 are formed in the vertical direction between the lower drainage cylinder 3 and the inner periphery thereof, and the water dehydrated by the upper drainage cylinder 1 is deodorized by the drainage holes 35 ... 35 and deodorant. It is guided to the drain 33 through the trap mechanism.

In the embodiment, the outer peripheral portion of the motor housing 5 is configured to be in close contact with the inner peripheral portion of the lower drainage cylinder 3, but the structure is not limited to this. For example, the outer diameter of the motor housing 5 may be lower. Forming the inner diameter of the drainage tube 3 slightly smaller than the inner diameter of the drainage tube 3, and supporting the motor housing 5 with a long locking screw (not shown) protruding inside the lower drainage tube 3 Is possible.

Inside the motor housing 5, the motor 4, the transformer 42, the power supply circuit control mechanism 43, etc. are housed.

The rotating force of the motor 4 is transmitted to the rotating shaft 41 via the speed reducing mechanism 44.

A watertight and earthquake-proof coupler mechanism 45 is formed at the tip of the rotary shaft 41, and the coupler mechanism 45 can be detachably fitted with the coupler mechanism 21 formed at the lower end of the dehydration basket 2. Is configured as follows.

In the coupler mechanisms 21 and 45 described above, when the dehydration basket 2 is housed in the upper drainage cylinder 1, the coupler mechanism 21 attached to the lower surface of the dehydration basket 2 protrudes above the motor housing 5 from the rotating shaft 41. Coupler mechanism 45 formed at the tip of
It is configured such that the rotation of the rotary shaft 41 can be accurately transmitted while being automatically fitted. (See Figure 4)

[0030]

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

(1) When the cooking waste (garbage) contained in the dehydration basket 2 is to be dehydrated, the closing lid 7 is fitted in the upper opening of the upper drainage cylinder 1 and the magnet attached to the closing lid 7 is used.
If the motor driving switch 14 buried in the opening peripheral portion of the upper drainage cylinder 1 is made to face each other, the sensor 71 of the hall element reacts with the magnet 71 to instantly drive the motor 4 to rotate the dehydration basket 2. Accurate centrifugal dehydration can be performed.

(2) The motor drive switch 14 is embedded in the upper drainage cylinder 1, and the switch 14 is driven only by aligning the position of the magnet 71 provided on the closing lid 7 with the switch 14. There are no accidents that may cause electric shock by touching the switch or being damaged by water.

(3) The motor housing 5 for rotating the dehydration basket 2 is of a completely sealed structure, and there is no risk of moisture intruding into the motor housing 5, so there is no risk of electrical leakage or electric shock, and it can be used with peace of mind.

(4) Upper drainage cylinder 1, lower drainage cylinder 3
Also, since the motor housing 5 containing the motor 4 is configured to be separable, maintenance inside the drain trap and maintenance of the motor mechanism can be performed very easily.

Further, in the unlikely event that the motor 4 fails, the motor housing 5 can be replaced by the assembly, and there is an advantage that the repair work can be easily performed.
