DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the garbage dewatering machine of the present invention will be described with reference to the drawings. FIG. 1 is an overall longitudinal sectional view showing a garbage dewatering machine according to a first embodiment, and FIGS.
It is the perspective view and sectional drawing which show the structure of the connection part of the rotating shaft and the dehydration basket in Example of this.

This garbage dewatering machine has a cylindrical case 22.
And a dewatering basket 24 disposed in the case 22, and a motor 26 for driving the basket 24 to rotate.

A housing 28 for holding a motor 26 is inserted into the case 22. This housing 2
Reference numeral 8 denotes a cylindrical shape, and the motor 26 is attached to a lower portion thereof.

The rotating shaft (rotor shaft) 2 of the motor 26
6a extends vertically upward. The upper end of the rotating shaft 26a is connected to a joint shaft 32 via a flywheel 30. The flywheel 30 includes screws 34 and 36
The shaft 26a and the joint shaft 32 are fixed to both the shaft 26a and the joint shaft 32, and also have a function as a joint for coaxially connecting the shafts 26a and 32. The joint shaft 32
Are pivotally supported on the upper portion of the housing 28 via bearings 38 and 40 and extend vertically.

The bottom 24b of the dewatering basket 24 is provided with a tapered hole 42 having a smaller diameter toward the upper side. The tapered hole 42 is a through hole penetrating the dewatering basket. A relatively thick boss portion 44 for maintaining strength is provided around the tapered hole 42 of the dewatering basket 24. A plurality of radial grooves 46 are provided on the lower end surface of the boss 44.

The head of the joint shaft 32 is tapered so as to engage with the tapered hole 42, and two pins 48 projecting radially are provided at the base of the tapered surface of the joint shaft 32. ing. The pin 48 is engaged with the groove 46 on the lower surface of the dewatering car 24 and transmits the rotation of the motor 26 to the dewatering car 24. The joint shaft 32 and the tapered hole 42 are configured such that when the joint shaft 32 is fitted into the tapered hole 42, the upper end of the joint shaft 32 slightly projects from the upper end of the tapered hole 42. In addition, 50 in FIG.
Denotes a lid detachably attached to the inlet, and 54 denotes an outlet for the dewatered drainage.

In the garbage dewatering machine thus constructed, the flange 22f at the top of the case 22 is installed so as to be engaged with the upper edge of a drain (not shown) of the sink. Garbage is put into the dewatering basket 24 of the garbage dewatering machine, and the lid 52 is attached. A magnet 56 is provided on the lid 52, and a reed switch (not shown) is provided on the upper edge of the case 22. The lid 52 is the case 2
When the reed switch 2 is mounted, the reed switch is turned on by the magnet 56, the motor 26 is activated, and the garbage is centrifugally dehydrated. The dehydrated water is discharged from the outlet 54.

In the garbage dewatering machine of the present embodiment, the connecting portion between the joint shaft 32 and the dewatering car 24 is configured so that the tapered shaft is engaged with the tapered hole 42. It is connected to the shaft 32 without play. Further, since the tapered hole 42 is formed as a through hole, when the dewatering basket 24 is mounted on the joint shaft 32, dust and dirt on the engaging portion are pushed out to the inner surface of the dewatering basket 24 by the joint shaft 32, This prevents the tapered hole 42 from remaining on the inner surface.

The dewatering basket 24 is detached from the joint shaft 32.
In this case, the dewatering basket 24 is simply pulled up and down. Accordingly, the work of attaching and detaching the garbage collection bag to and from the dewatering basket 24 becomes easy. Also, even when the garbage bag is thrown into the dewatering basket 24 in a state where the garbage collection bag is forgotten to be attached to the dewatering basket 24, the garbage can be removed and collected by removing the dewatering basket 24 from the garbage dewatering machine. Re-attachment of the bag can be performed easily and reliably.

FIG. 4 is a perspective view of a main part of a garbage dewatering machine according to a second embodiment of the present invention. In this embodiment,
The boss portion 44 the lower end surface of the dewatering basket 24 bottom, as the engaging portion, bevel gear-shaped corrugated surface 56 is provided. Joint shaft 3
2 pin 48 engages with the concave portion of the wavy surface 56 to
The rotation of No. 6 is transmitted to the dewatering basket 24a. In the embodiment shown in FIGS. 1 to 3, in order to engage the pin 48 with the groove 46, it is necessary to rotate the dehydrating cage 24 in the rotation direction to align the pin 48 with the groove 46. , Dehydrated basket 24A
Is dropped into the case 22, the pin 30 is engaged with the concave streak of the corrugated surface 56 as it is.

FIG. 5 is a perspective view of a joint shaft 32B used in the garbage dewatering machine according to the third embodiment of the present invention, and FIG. 6 is a perspective view of the garbage dewatering machine according to the fourth embodiment of the present invention. It is a perspective view of the joint shaft 32C used.

The joint shafts 32b, 32 shown in FIGS.
c is configured to be engaged with the tapered holes of the dewatering baskets 24B and 24C having engagement with the corrugated surface 56 of the second embodiment, respectively. The joint shaft 32b has a large number (six in this embodiment) of pins 48. Joint shaft 32c
A flange 58 is provided at the base of the tapered surface, and a wavy surface 60 meshing with the wavy surface 30 is provided on the upper surface of the flange 58.

FIGS. 7 and 8 are a perspective view and a sectional view of a joint shaft 32d used in a garbage dewatering machine according to a fifth embodiment of the present invention, and FIGS. 9 and 10 are sixth embodiments of the present invention. It is the perspective view and sectional drawing of the joint shaft 32e used for the garbage dewatering machine which concerns on (a). The joint shaft 32d is a tapered joint shaft having a regular octagonal cross section, and the joint shaft 32e is a joint shaft having an outer peripheral surface subjected to spline processing.

The cross-sectional shapes of the fitting holes provided on the axis of the dewatering cages 24D and 24E with which the joint shafts 32d and 32e are engaged have the shapes shown in FIGS. Therefore, since the rotational force of the joint shaft can be transmitted to the dewatering basket without slipping together, the pin or the wavy surface provided on the joint shaft as in the above-described first to fourth embodiments and the boss portion on the lower surface of the dewatering cage are provided. It is not necessary to engage with the groove or the wavy surface provided in the.

In the above embodiment, the joint shaft is used. However, in the present invention, the joint shaft is omitted, and the rotating shaft (rotor shaft) of the motor may be directly engaged with the tapered hole of the dewatering basket. good.

The shape of the rotating shaft or the joint shaft of the garbage dewatering machine of the present invention and the through hole of the dewatering basket may be any shape as long as the rotation of the motor 26 can be reliably transmitted to the dewatering basket 24. The good is clear.

[0032]

According to the garbage dewatering machine of the present invention, the dewatering basket and the rotating shaft of the motor or the joint shaft fixed to the rotating shaft are provided.
The the connection part, not the screw member such as a nut is used to secure the dewatering basket to the rotation axis or the like. Accordingly, the dewatering basket can be easily attached and detached regardless of the presence or absence of the garbage bag, and workability such as setting of the garbage collection bag, maintenance and inspection, and cleaning is improved.

Further, because of the penetrations holes, when mounting the dewatering basket to the rotating shaft or joint shaft, dust and dirt of the mating surface is pushed to the basket inner surface by the rotating shaft or joint shaft, through It is not trapped in the inner surface of the hole . Therefore, the fitting between the dewatering basket and the rotating shaft or the joint shaft can be always performed without play.
