[0016]

According to the invention of claim 1, since the upper end side of the dehydrating car is supported by the upper supporting portion so as to be rotatable about the shaft center, the dehydrating car is supported on both sides in the axial direction. Therefore, even if the garbage thrown into the dehydration basket from the inlet becomes unevenly distributed, it is possible to rotate the dehydration basket without shaking. For this reason, it is possible to effectively suppress the generation of noise due to the vibration, and by reducing the vibration during the rotation of the dehydration basket, the proper rotation speed of the dehydration basket is maintained, and the predetermined dehydration function is achieved. It can be fully demonstrated.

Here, as in claim 2, if the central shaft portion of the inner lid of the dehydration basket is supported by the bearing provided on the safety lid of the charging port, the structure is relatively simple. It is possible to prevent the dehydration basket from swinging, and if the bearing provided on the inner surface on the upper end side of the outer case supports the upper opening end side of the dehydration basket, the dehydration basket can be supported. The vibration of the dehydration basket can be reduced without applying an excessive concentrated load to the bearing when rotating.

It is possible to reduce the generation of noise and vibration during the dehydration process, as compared with the case of using.

Further, if a balancer is provided on the rotation transmission shaft for the dehydration car as in claim 6, the vibration control function of the balancer works when the dehydration car rotates, and the vibration of the dehydration car is sufficiently suppressed. In addition, the generation of noise can be further reduced.

When a balancer for damping is used,

Further, if the balancer itself has the shape as claimed in claim 11, even if dew condensation occurs on the surface of the balancer and the water drops run off, the water drops are treated without directly touching the motor or the like, and a short circuit or the like occurs. It is possible to avoid the occurrence of dangerous situations.

According to a fifth aspect of the present invention, a metal substrate is used which is a combination of a metal plate having a lower surface coated with an insulating material and a substrate having a circuit pattern formed on the coating surface. When holding the motor and electric circuit parts, the metal plate plays the role of a heat radiating plate, enhances the heat dissipation effect, and the temperature rise at the time of energizing the electric circuit parts becomes gentle, and the continuous energizing time, that is, the dehydration treatment device. It is possible to prolong the continuous use time of and to extend the life of the parts.

Further, according to a twelfth aspect of the present invention, a uniform magnetic attraction force is generated around the axis between the magnetic body on the outer surface side of the bottom of the dehydration basket and the permanent magnet arranged opposite to the magnetic body. When configured, the inclination of the dehydration basket is always corrected, and the rotation can be performed without swinging.
When the bottom side of the dehydration basket is formed into a substantially inverted conical shape, as in the above, the garbage thrown into the dehydration basket will not be unevenly accumulated and the inertia during rotation of the dehydration basket will be reduced. The moment is reduced and vibration is suppressed. Furthermore, when the lid is provided with the operation display unit including the power generation motor that operates by the rotation of the dehydration basket and the operation indicator lamp as in claim 14, the rotation state of the dehydration basket can be easily confirmed. In addition, it is not necessary to provide a power source battery for the lid, and there is no wiring to the outside, so that the structure can be simplified.

According to the fifteenth aspect of the present invention, since the plurality of types of cooking attachments can be replaced by the rotation transmission shaft via the holder, it is not limited to the single function of dewatering the kitchen waste, and the dewatering process is performed. It is possible to effectively utilize the drive source such as a motor provided in the device and the sink sink in which the device is installed for a plurality of types of cooking functions related to kitchen work. It is possible to realize multi-functionality of this by a simple operation just by preparing.

Further, in the above-mentioned multi-functionalization, claim 1

Reference numeral 9 denotes a rotation transmission shaft located on the axis X and penetrating the bottom wall 1b of the outer case 1. The rotation transmission shaft 9 has a pair of upper and lower bearings 11 and 11 fixed to a bearing holder 10 on the bottom wall 1b side. It is rotatably supported, and at its upper end, a holder 12 fitted to the concave portion 7 of the connecting member 8 and applying a rotational force to the dehydration basket 6 is fixed by a screw 13 or the like.
Reference numerals 14 and 15 are an engagement groove and an engagement protrusion which are respectively formed on the connecting member 8 and the holder 12 and engage with each other in a detachable manner. Reference numeral 16 is a seal member interposed between the bearing holder 10 and the rotation transmission shaft 9.

Reference numeral 17 denotes a lower case mounted on the lower side of the bottom wall 1b of the outer case 1, and inside thereof, a drive case 19 is constituted together with an upper chamber 18 linked to the bearing holder 10. A lower chamber 20 is disposed therein, and the drive unit case 19 contains a substrate 21, a motor 22 attached to the substrate 21, and the like. Reference numeral 23 denotes a drive shaft connected to the lower end side of the rotation transmission shaft 9 via a coupling member 24A. The drive shaft 23 has a driving roller 24 fixed to the rotation shaft 22a of the motor 22.
Ring-shaped driven roller 25 that is frictionally driven by rolling contact with
The driven roller 25 and the driving roller 24 reduce the rotational force of the motor 22 to reduce the rotational force of the motor 22 and transmit the reduction mechanism 26 for frictional rotational force transmission to the rotation transmission shaft 9 side in a high torque state. I am configuring. 27 is the substrate 2
It is an electric circuit component such as a transformer mounted on the No. 1.

28 is an upper end opening end portion 6b of the dehydration basket 6.
It is a reverse tray-shaped inner lid body that is detachably attached to a central shaft portion 29 protruding from the upper surface thereof. Reference numeral 30 denotes a bearing that is located on the axis X and is fixed in the central handle portion 31 of the lid body 5. By pressing the central shaft portion 29 inside the bearing 30, the inner lid The dehydration basket 6 is rotatably supported via the body 28. That is, the inner lid body 28 and the bearing 29 form an upper support portion 32 that supports the upper end side of the dehydration basket 6 around the axis X.

A vibration control balancer 33 made of metal or the like having a relatively large mass is attached to the rotation transmission shaft 9 so as to be positioned below the bearings 11, 11 serving as lower support portions of the dehydration basket 6. Has been.

Next, in order to dehydrate the kitchen waste M for explaining the operation of the kitchen wastewater dehydrating apparatus having the above-described structure, first, the central handle portion 31 of the safety lid body 5 is grasped and the lid body 5 is removed.
The inner lid 28 is also integrally removed via the bearing 30, and the charging port 3 is opened. Then, the kitchen waste M is put into the dehydrated basket 6. At this time, since the bottom 6a side of the dehydration basket 6 has a substantially inverted conical shape, the kitchen waste M is deposited on the center side inside the dehydration basket 6. The dehydration basket 6 may be one in which a net bag for kitchen waste can be attached.

After the kitchen waste M is put into the dehydration basket 6,
When the lid 5 is fitted into the upper opening end 1c of the outer case 1 to close the charging port 3, the inner lid 28 is also fitted into the upper opening end 6b of the dehydration basket 6. By closing the input port 3 with the lid 5, it is possible to prevent the user from accidentally touching the dehydration basket 6 during the dehydration, and to prevent the kitchen waste M from scattering from the inside of the dehydration basket 6. Rubber packing 5
Since the inlet 3 is liquid-tightly closed by A, water can be stored in the think tank S.

When the charging port 3 is closed by the lid 5,
The connecting member 8 on the dehydration basket 6 side is the holder 1 on the rotation transmission shaft 9 side.
If the two are not properly fitted, the lid 5 is lifted and the detection switch (not shown) is not turned on. Therefore, by pushing the lid 5 downward, the connecting member 8
The holder 12 can be properly fitted to the holder 12, and the detection switch is turned on.

With the detection switch turned on,
For example, if an external start switch is turned on, the motor 22
Is activated, and its rotational force is driven by the driving roller 24 and the driven roller 2.
5 is transmitted to the drive shaft 23 via a friction type rotational force transmission reduction mechanism 26. The rotation of the drive shaft 23 is transmitted to the rotation transmission shaft 9 via the coupling member 24, so that the dehydration basket 6 rotates in the same direction around the axis X via the holder 12 and the connecting member 8. Basket 6
The kitchen waste M inside is dehydrated by the rotating centrifugal force, and the dehydrated water is discharged from the drain port 4 of the outer case 1.

Here, the dehydration basket 6 has its lower end side supported by the bearings 11 and 11, while its upper end side is supported by the bearing 30 in the upper support portion 32, so to speak, in a vertically supported state. Therefore, during the dehydration operation, the shaft rotates around the axis X without swinging, and the vibration is greatly reduced. Therefore, there is no possibility that the vibration is transmitted to the sink S side and becomes a large noise. In particular, when the rubber packing 5A is provided on the outer peripheral portion of the lid 5 as in the present embodiment, it is effective in absorbing the vibration.

Further, since the bottom 6a side of the dehydration basket 6 has a substantially inverted conical shape, the garbage M thrown into the dehydration basket 6 gathers near the axis X, and the garbage M is less likely to be unevenly deposited. The moment of inertia during rotation of the dehydration basket 6 is reduced, and the above vibration is further suppressed.

Further, even if the dehydrating basket 6 is inclined due to the difference in mass of various garbage M in the dehydrating basket 6, the rotation transmission by the balancer 33 provided on the rotation transmitting shaft 9 is performed. Since the shaft runout of the shaft 9 is suppressed, the inclination of the dehydration basket 6 is suppressed, and the occurrence of vibration can be effectively prevented, and the rotational force of the motor 22 is reduced by the friction type rotational force transmitting speed reduction mechanism 26. Since it is transmitted to the drive shaft 23 and the rotation transmission shaft 9 via the, the generation of noise is very small.

FIG. 2 is a vertical cross-sectional front view of a kitchen waste dehydration treatment apparatus according to another embodiment of the present invention. In FIG. 2, the same or corresponding parts as those in FIG. The description is omitted. In FIG. 2, 41 is the axis X
The bearing is fixed to the inner periphery of the outer case 1 near the upper opening end 1c of the outer case 1, and the upper opening end 6b of the dehydration basket 6 is press-fitted and fixed inside the bearing 41, thereby An upper support portion 42 that supports the upper end side of the dehydration basket 6 around the axis X is configured.

The dehydrated basket 6 has a flat bottom 6a side, and a disk-shaped magnetic plate 43 made of iron or the like is fixed to the outer surface of the bottom 6a, and the magnetic plate 43 is fixed. Annular permanent magnets 44 facing each other with a gap G between them
Is fixed on the bottom wall 1b of the outer case 1 by being located on the axis X.

Also in the case of the kitchen waste dewatering apparatus of the embodiment shown in FIG. 2, the upper open end 6b side of the dewatering basket 6 is the bearing 4
Since the dehydration car 6 is supported by the unit 1 and rotates in a vertically supported state in which the dehydration car 6 is tilted, the dehydration car 6 tilts even when the kitchen waste M thrown into the dehydration car 6 is unevenly accumulated. Therefore, the vibration does not occur, so that the generation of vibration can be suppressed, and an unreasonable load is not concentrated on the bearing 41 during the dehydration operation.

Furthermore, since the magnetic attraction force acts evenly around the axis between the magnetic plate 43 on the bottom 6a side of the dehydration basket 6 and the permanent magnet 44, the kitchen M is uneven in the dehydration basket 6. If the magnetic attraction force exceeding these masses is generated even when they are accumulated on the surface, the dehydration basket 6 is less likely to swing during rotation, and vibration can be reduced.

When is rotated, the inner lid 28 rotates together with the dehydration basket 6, so that the central shaft portion 29 drives the power generation motor 53. Since the LED 51 is turned on by the electromotive force generated by the power generation motor 53 via the control circuit 52,
The dehydration operation can be confirmed from the outside. That is,
In this case, the rotation of the inner lid 28 is used to drive the motor 53 for power generation, and the electromotive force thereof causes the LED 51 to light up. Therefore, the LED 51 can be directly attached to the lid 5 and the lid 5 can be supplied with a power supply battery. It is not necessary to hold the above or to provide wiring between the lid 5 and the outside.
