Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a waste dewatering device attached to a sink, which is mainly attached to a drain port of a sink to separate solid waste from drainage, and which is capable of dewatering the waste in a timely manner by rotating a motor.

[0002]

[Prior art]

 A conventional dehydrator of this type is disclosed in, for example, JP-A-63-189302.

[0003]

[Problems to be solved by the device]

 The conventional dewatering device described above includes a tubular container body connected to the back side of the drain port of the sink, and a garbage basket rotatably supported by being detachably fitted in the container body. A motor for rotating the basket dehydration is installed below the container body, and a gear transmission mechanism is provided between the output shaft of the motor and the input shaft that is hung from the bottom rear surface of the garbage basket and penetrates the bottom of the container body. Was provided to drive the above-mentioned garbage basket to rotate.

[0004] The conventional device in which the garbage basket is rotated as described above requires a large installation space because the entire device becomes long. The weight of the rotary transmission mechanism increases. The vibration and noise generated when the garbage basket rotates are loud. It is necessary to make the seal of the bearing around the rotating shaft strict, and there are drawbacks such as technical difficulties in waterproofing. For this reason, the dewatering device for garbage baskets is made compact and lightweight, which reduces vibration during dewatering and simplifies the waterproof structure to facilitate attachment to the sink. It was a problem to be solved in.

[0005]

[Means for Solving the Problems]

 Therefore, the present invention proposes a cylindrical container body connected to the back side of the drain of the sink, a garbage basket detachably fitted in the container body and rotatably supported, and a dewatering rotary of this garbage basket. The present invention provides a dewatering device for a waste attached to a sink, characterized in that a fixed member of the brushless motor is attached to the container body side, and a movable member is attached to the dust basket side.

[0006]

[Action]

 As described above, the dewatering device of the present invention, which has a movable member attached to the garbage basket side and a brushless motor with a fixed member attached to the container body side, directly drives the garbage basket to rotate, Since no special rotary transmission mechanism is required, the entire device becomes compact and lightweight. In addition, there is little vibration when rotating the garbage basket, the operating noise is quiet, and the waterproof structure of the rotating part is simple, and it is easy to attach. The present invention has solved the above problems as described above.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, this dehydrator includes a container body 1 having a cylindrical shape, a dust basket 2 which is detachably fitted in the container body 1 and rotatably supported, and a container body 1 side and a dust container. It is provided with a brushless motor 3 separately attached to the basket 2 side.

The container body 1 holds a rim of a drain port 8 of a sink 7 between a flange 4 protruding to the outside of the upper end and a retaining ring 6 joined from the back side through a waterproof packing 5 to form a seal. It is fixed integrally with the link 7. The garbage basket 2 is provided with a flange 9 projecting outward at the upper end, the flange 9 is superposed on a bearing ring 10 fitted on the inner circumference of the upper part of the container body 1, and a rotary support ring fitted under the flange 9 is attached. 11 is brought into contact with the inner peripheral surface of the container body 1, and the small concave portion 12 provided in the center of the bottom rear surface is fitted into the small convex portion 13 provided on the upper surface of the bottom portion of the container body 1. By forming it vertically and separating the flange 9 from the bearing ring 10, it can be taken out upward from the drain port 8 of the container body 1 and the sink 7.

In this embodiment, a magnetic levitation type brushless motor is used as the brushless motor 3, and a ring-shaped magnet is fixed and movable on the peripheral surface of the dust basket 2 so as to form a concentric circle with the rotation center. As a member 14, a fixing member 17 in which a coil 16 is wound around a large number of annular yokes 15 is fixed to the outer peripheral surface of the container body 1 facing the movable member 14, and electricity is supplied by the operation of a switch (not shown). The dust basket 2 in the container body 1 is rotated in one direction while floating, and then rotated in the opposite direction. The dust basket is wiped off from the inner peripheral surface of the dust basket 2 and then stopped.

The drainage passing through the garbage basket 2 passes through a trap portion 18 formed integrally with the bottom of the container body 1 to the outside of the system through a pipe (not shown) connected to the lower portion of the container body 1. Is discharged. Further, in the figure, 19 is a rubber latch ring fitted in the opening of the container body 1, and 20 is a lid fitted in the rubber latch ring 19 to prevent water from splashing during the water removal operation. ing.

In implementing the present invention, the mounting position of the brushless motor 3 is not limited to the illustrated position, and for example, when the movable member 14 is mounted on the bottom rear surface of the dust basket 2 and the fixing member 17 is mounted on the bottom portion of the container body 1. There is also. In addition, the container body 1 may not include the trap portion 18 integrally. Further, the support structure and the like of the garbage basket 2 are not limited to those shown in the figures, and the design can be changed arbitrarily according to the gist of the present invention.

[0012]

[Effect of device]

 As described above, according to the present invention, the fixed member of the brushless motor is attached to the cylindrical container body side connected to the back side of the drain port of the sink, and the movable member of the motor is detachably fitted in the container body. It is attached to the trash basket side that is rotatably supported together, and the trash basket is driven to rotate by the drive of the brushless motor.Therefore, a rotation transmission mechanism can be omitted for the trash basket, which is the object to be rotated. , The entire device is compact and lightweight, and there are less volume restrictions on attachment to the sink.

Further, by using a brushless motor, vibration and vibration noise are extremely reduced, which enables quiet operation. Further, since rotation can be generated only by attaching a support structure for supporting rotation of the dust basket to the container main body, there is an advantage that a waterproof structure for a rotating portion unlike the conventional device is unnecessary. The present invention has excellent practical effects as described above.
