The present invention relates to a food waste dehydrator installed in the sink, and more particularly, to a food waste dehydrator using a magnetic force to rotate the dehydrated food waste installed in the sink.

Various environmental pollutions due to the increase in population are becoming a social problem every day. Among them, the disposal of household waste is a serious problem. In particular, the food waste, which constitutes a large part of the household waste, is very difficult to be disposed of, leading to a serious situation.

In particular, since food waste generally contains a large amount of water, such water has become wastewater and has become a factor such as soil pollution and groundwater pollution even after landfilling. As it was destroyed, problems such as odor and harmful gas were generated to pollute the surrounding environment.

In order to reduce this problem, it is required to remove and dispose of food wastes in water, and a dehydrator is installed under the sink in order to remove water from food wastes in homes and businesses.

Food dehydrator 200 is installed in the opening 112 of the sink 110 according to the prior art, as shown in Figure 5, the dehydration container 120 is fixed to the upper end is fixed to the opening 112 of the sink. And a cover 160 covering the rotor 130 and the filter 150 installed in the dehydration container 120 and the opening 121 of the upper end of the dehydration container 120.

The dehydration container 120 includes a motor chamber 124 in which a motor 131 of a rotator is installed below the partition wall 122 with respect to the partition wall 122 formed in the middle, and a filter 150 at the upper part of the partition wall 122. It is configured to include a drain box 126 located. The interface portion is packed to prevent moisture from leaking to the interface between the rotor 130 and the partition wall 122. The drain container 126 has a drain hole 128 that discharges the dehydrated water to the outside at the boundary portion where the partition wall 122 and the inner surface meet.

The rotor 130 is installed so that the driving shaft 133 protrudes from the bottom surface of the partition wall 122 into the drain container 126, and the filter 150 is disposed on the driving shaft 133 protruding from the bottom surface of the partition wall 122. Is combined. The drain hole 128 is formed in the boundary part where the bottom surface and the inner surface of the partition 122 meet.

In addition, the filter 150 has a cylindrical shape having a bottom surface and an opening portion 152 is formed to accommodate food waste at an upper portion thereof. A plurality of slots 153 are formed. Here, the shaft coupling portion 154 is formed at a predetermined height at the center of the bottom surface of the filter 150 so that the drive shaft 133 of the rotor can be inserted and coupled through the lower surface of the filter 150.

Therefore, the conventional food waste dehydrator 200 is a predetermined amount of food waste is received in the filter 150, the filter 150 is closed with a cover 160 and then driven by the rotor 130 is coupled to the drive shaft 133 Moisture contained in the food waste by rotating the filter 150 is passed through the slot 153 of the filter is sent to the drain 126, the water moved to the drain 126 is the sink (through the drain 128) 110) is discharged out.

Since the conventional food waste dehydrator 200 has a structure in which the shaft coupling portion 154 of the filter is directly coupled to the drive shaft 133 of the rotating machine, the filter 150 rotates the shaft coupling portion 154 with the rotary shaft and filters the filter. The water contained in the food waste contained in 150 is dehydrated.

Here, there is no problem when the food waste is uniformly accommodated around the shaft coupling portion 154 of the filter, but when the food waste is accommodated in the filter 150 in a biased manner, the filter 150 shafts the shaft coupling portion 154. Due to the incomplete rotational movement, the filter 150 collides with the inner circumferential surface of the sump 126 to generate noise, and may cause a defect in not properly dehydrating water in the food waste accommodated in the filter 150. .

In addition, due to incomplete rotational motion due to the food waste, the packing portion between the drive shaft 133 and the bottom surface of the partition wall 122 may be damaged and leaks may occur. The leaked water may flow into the rotor 130 to cause an electric shock or a fire.

For this reason, the food waste dehydrator 200 according to the prior art having the filter 150 directly coupled to the drive shaft 133 of the rotor has to be replaced with a considerable drop in durability after one to two years.

Therefore, the first object of the present invention is to minimize the occurrence of incomplete rotational movement even if the bias of food waste is generated in the filter to suppress the generation of noise.

The diamagnetic plate 47 may transmit the magnetic force of the magnet 43 installed on the rotating plate 41 to the magnet 55 mounted on the filter 50, wherein the magnets 43 and 55 are the diamagnetic plate. Synthetic resin, such as plastic, stainless steel, etc. can be used so that it may not adhere to 47.

The motor 31 has a drive shaft 33 protruding upward. The motor case 35 is installed on the outer circumferential surface of the motor 31 higher than the upper end of the drive shaft 33. In order to prevent an overload that may be generated by directly supplying external power to the motor 31, the external power may be supplied to the motor 31 via the condenser 39.

The rotating plate 41 is fastened to the drive shaft 33 of the motor and rotates along the drive shaft 33 to provide rotational force to the filter 50. A ring-shaped magnet 43 having a predetermined thickness is fixed to the fixed plate 45. Has a structure embedded in). At this time, the fixing plate 45 surrounds the outer circumferential surface of the magnet 43 except for the upper surface of the magnet 43 and has a coupling hole 46 to which the driving shaft 33 of the motor can be coupled. For example, it is fixedly installed by means such as the nut 37 so that the tip of the drive shaft 33 can be located in the engaging hole 46 of the rotating plate.

Meanwhile, the rotating plate 41 is installed to be spaced apart from the upper surface of the motor 31 under the driving shaft 33 so that the rotating plate 41 may rotate along the driving shaft 33 of the motor, and the upper surface of the magnet 43 is fixed plate 45. It is installed to be exposed up.

In addition, the diamagnetic plate 47 is fixedly installed on the motor case 35 so as to be located close to the rotating plate 41, and the central shaft 49 is formed at a predetermined height so that the filter 50 can be coupled to the center portion. Formed. In this case, the central axis 49 may preferably use a metal material to stably rotate the filter 50, and the central axis 49 may be fixed by welding to the diamagnetic plate 47.

At this time, the rotating plate 41 and the diamagnetic plate 47 is installed in the motor case 35, the upper surface of the anti-magnetic plate 47 is installed so that it can be located almost the same surface as the upper surface of the motor case 35.

Therefore, since the central axis 49 of the diamagnetic plate is separated from the drive shaft 33, and the diamagnetic plate 47 has a structure inherent in the motor case 35, the central axis 49 does not rotate.

The filter 50 accommodates food waste introduced through the opening 12 of the sink, and is a means for filtering large food waste except water and small food waste contained in the food waste during rotation. It is inserted into the 49 and installed close to the diamagnetic plate 47, the magnet 55 is buried in the lower surface so that the pole opposite to the magnet 43 of the rotating plate can face.

The filter 50 includes a cylindrical filter body 51 having an open top and a ring-shaped magnet 55 installed on the bottom surface of the filter body 51. The filter body 51 has a cylindrical shape having an open portion 52 and a bottom surface to allow food waste to enter through an upper portion thereof. The filter body 51 has a vertical shape around an outer circumferential surface so that water and small food waste can escape when dewatering. A plurality of slots 53 are formed, and an insertion portion 54 into which the central axis 49 of the diamagnetic plate is inserted at a predetermined height is formed on the bottom surface. The bottom surface of the filter body 51 is formed with a plurality of through-holes 56 so that the moisture of food waste entering the filter body 51 can be drained down.

Magnet 55 is in the form of a ring having a predetermined thickness, is fixed around the lower surface of the filter body 51 around the insertion portion 54 of the filter body.

Accordingly, the rotating plate 41 rotates by the rotation of the drive shaft 33 according to the driving of the motor 31, and the filter 50 is rotated on the diamagnetic plate 47 by the magnetic force of the rotating plate 41. Will rotate.

In both cases, the lid 61 and the magnet switch 71 are positioned at the contact portion of the lid 60 and the upper end of the sump 26.

Referring to the method of dehydrating food waste using the food waste dehydrator 100 according to the embodiment of the present invention installed in the opening 12 of the sink, a predetermined amount of food waste is stored through the opening 12 of the sink. Upon entering the filter 50, the upper end of the sump 26 is closed by the cover 60 at the user's discretion.

Next, when the cover 61 is rotated or pressed to contact the magnet 61 of the cover with the magnet switch 71, the controller 72 operates the motor 31 of the rotor to rotate the drive shaft 33. Then, the rotating plate 41 coupled to the drive shaft 33 is rotated at a predetermined speed. In addition, the rotating plate 41 and the filter 50 constrained by magnetic force rotate in the rotation direction of the rotating plate 41.

Water and small food waste contained in the food waste contained in the filter 50 by the centrifugal force by the rotation of the filter 50 are discharged to the drain container 26 through the slot 53 of the filter and the slot 53 of the filter. Large food waste that does not pass through remains in the filter 50. Then, the water and small food wastes exiting into the sump 26 are discharged out of the sump 26 through the drain 28 connected to the sump 26.

In particular, the filter 50 is inserted into the central axis 49 of the fixed diamagnetic plate and rotates about the central axis 49, but the lower surface portion of the filter 50 close to the central axis 49 is magnetically driven. Since it is constrained by the rotary plate 41 and rotates by the rotational force of the rotating plate 41, even if the food waste is accommodated in the filter 50 so as to be slightly biased, vibration noise is hardly generated and dewatered.

That is, the diamagnetic plate 47 is fixed without being affected by the rotation of the drive shaft 33 and the rotating plate 41 coupled to the motor, the filter 50 is a magnet mounted in the filter 50 55 is to be rotated by the magnetic force generated by the rotation of the rotary plate 41.

In addition, the central axis 49 of the diamagnetic plate 47 is fixed because the diamagnetic plate 47 does not rotate, the central axis 49 serves to support the center of the filter 50. will be.

As a result, the drive shaft 33 does not rotate the filter 50 directly, but indirectly rotates the filter 50 by the magnetic force between the filter 50 and the rotating plate 41 coupled to the drive shaft 33, so that the motor The motor 31 maintains durability for the life of the motor 31 unless it is a fault of itself 31.

On the other hand, the embodiments of the present invention disclosed in the specification and drawings are merely presented specific examples to aid understanding, and are not intended to limit the scope of the present invention. In addition to the embodiments disclosed herein, it is apparent to those skilled in the art that other modifications based on the technical idea of the present invention may be implemented.

Therefore, according to the structure of the present invention by rotating the filter along the rotating plate rotated by the drive of the motor in the state in which the rotating plate coupled to the motor below the diamagnetic plate around the diamagnetic plate restrains the filter on the diamagnetic plate by magnetic force. Since the food waste contained in the filter is dewatered, even if the food waste is slightly biased into the filter, vibration noise can be dehydrated with little generation of vibration noise. That is, since the lower part of the filter is rotated by being constrained by magnetic force, rather than being supported and rotated on one shaft as in the related art, even if food waste is accommodated in the filter with a slight bias, it can dehydrate with little vibration noise. .

In addition, since the drive shaft rotates the filter indirectly by the magnetic force between the filter and the rotating plate coupled to the drive shaft rather than directly rotating the filter, it is possible to maintain the durability of the motor for the life of the motor, unless the motor itself.                     

In addition, since the drive shaft of the motor and the central axis of the diamagnetic plate is separated, and the central axis has a structure that is completely sealed to the reflective plate by welding or the like, it is to prevent the electric shock or fire that may occur due to leakage.

In addition, the magnet is installed on one side of the lower end of the cover and the one side of the upper end of the drain can be configured to control the driving of the motor by receiving a detection signal from the magnet switch for detecting the contact with the magnet of the cover, If the cover is installed in the drain without the switch operation of the dehydration process is in progress has the advantage of convenience.
