Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to the decomposition of garbage using microorganisms even in facilities such as schools, kindergartens, and nursery schools where the amount of garbage is large, and in households where the amount of garbage is small. The present invention relates to a garbage disposal apparatus suitable for carrying out.

[0002] The inventor of the present invention has disclosed in Japanese Patent Application No. 6-28280.
As a first issue, a garbage disposal apparatus having a structure in which a stirring screw is arranged inside a stirring cylinder and rotated, the garbage is raised by the stirring screw, and overflows outside the stirring cylinder is proposed.

However, as described above, when a structure is employed in which the stirring screw is rotated inside the stirring cylinder, the bone and the like mixed in the garbage are disposed between the inner wall of the stirring cylinder and the stirring screw. There was a problem that a hard object was caught and as a result, the stirring screw could not be rotated.

Since the garbage must be forcibly transported upward by a screw inside the stirring cylinder, it is necessary to rotate a large-sized, high-output motor at a high speed. As a result, loud motor noise is generated and noise is generated. Cause. In addition, the cost is inevitably high, and it is not suitable as a small household garbage disposal device.

[0005] By solving such a problem and enabling the circulation and stirring of garbage without using a stirring screw, the load on the motor can be reduced, and the operation is reliable.
In order to make it possible to realize a large-sized machine to a small-sized machine at low cost, an improved structure such as Japanese Patent Application No. 9-102587 has been proposed.

[0006]

2. Description of the Related Art FIGS. 1 to 10 are views for explaining the improved structure proposed above, and FIG. 1 is a longitudinal sectional view showing the whole garbage disposal apparatus. Reference numeral 1 denotes a main body of the garbage disposal apparatus, which has a cylindrical shape. The inside 2 of the main body 1 is a processing chamber.

[0007] With a space between the bottom plate 3 of the processing chamber 1 and
The overflow cylinder 4 is set up, and the horizontal support member 5 is passed between the upper end of the overflow cylinder 4 and the main body side wall 1 to fix the overflow cylinder 4. A horizontal upper rotating blade 6 is provided above the horizontal supporting member 5 and attached to a rotating shaft 7.

The vertical rotating shaft 7 is erected at the center of the overflow cylinder 4 and the upper and lower ends are bearings B1, B
2 and the upper end is connected to the drive motor. A lower rotating blade 8 is attached to the rotating shaft 7 below the overflow cylinder 4. Processing room bottom plate 3
On the upper side, one or a plurality of cutter members 9 are fixed substantially in the radial direction, and the lower rotating blades 8 are rotated above the upper side thereof at a certain interval.

The overall structure of the garbage disposal apparatus having the improved structure is as described above. Next, the details of each part will be described. FIG. 2 is a horizontal cross-sectional view taken along the line AA in FIG. 1. For example, three strip-shaped iron plates 9 are radially fixed to the bottom plate 3 of the processing chamber by welding.

The iron plate 9 functions as a cutter member. However, the iron plate 9 does not necessarily have to be radial, and by making an angle of α with respect to the radiation direction, the lower rotating blade 8 can be used when the lower rotating blade 8 passes. Since the passing position is gradually moved so that the cutting edge is closed, the load on the motor when cutting fibrous garbage or the like is reduced. Note that the cutter member 9 may also be inclined like the lower rotating blade 8 described above.

FIG. 3 is a horizontal sectional view taken along the line BB in FIG. 1. A lower rotating blade 8 is arranged on the cutter member 9 at a certain interval, and is attached to the rotating shaft 7. It is fixed radially. Note that the lower rotating blades 8
Although two sheets are provided at an interval of 80 degrees, three or more sheets may be arranged at a constant angle interval.

FIG. 4 is a horizontal sectional view taken along the line C--C in FIG. 1. The overflow cylinder 4 is disposed above the lower rotating blade 8 at a certain interval, and the upper end of the overflow cylinder 4 is placed at the upper end. As described above, it is fixed to the side wall 1 of the processing chamber via the horizontal support member 5. In the illustrated example, three horizontal support members 5 are provided radially, and one of them is extended to the inside of the overflow cylinder 4.

The overflow cylinder 4 has a radius R larger than its height H as shown in FIG. The lower end of the overflow cylinder 4 has a triangular wave shape such as a sawtooth shape.

FIG. 5 is a horizontal sectional view taken along the line DD in FIG. 1. The upper rotating blades 6 are arranged on the horizontal supporting member 5 at a certain interval, and Axis 7
Is fixed radially. This upper rotating blade 6
Is preferably the same number as the lower rotating blades 8, and
On the other hand, the upper rotating blades 6 are shifted in the circumferential direction.

As shown in FIG. 1, the upper rotating blade 6 has an upper surface inclined forward and downward, and the lower rotating blade 8 also inclined forward and downward as shown in FIG. As shown in FIG. 1, the lower rotating blade 8 and the upper rotating blade 6 are fixed by welding a member having high strength such as an angle 10 to the back surface thereof, and the angle 10 is radially attached to the rotating shaft 7. It is preferred to fix to.

FIG. 6 is a sectional view for explaining the stirring and mixing operation of garbage in the garbage processing apparatus. In this garbage disposal apparatus, bacteria that decompose garbage are mixed with the garbage, and are charged into the processing chamber 2 to a position higher than the overflow cylinder 4. Therefore, the overflow cylinder 4 is not made too high so that a small amount of garbage can be processed. Figure 1
As shown in the figure, a structure in which the height H is smaller than the radius R may be used.

When the rotating shaft 7 is rotated by the motor, the lower rotating blade 8 and the upper rotating blade 6 are driven to rotate. When the lower rotating blade 8 rotates through the garbage 11, FIG.
As shown in the figure, the garbage 11 is pushed up by the lower rotating blades 8 and rises like 11a. As a result, the garbage in the raised portion 11a overflows from the outside of the overflow cylinder 4 to the inside and falls.

By repeating this operation, as shown by arrows in FIG. 6, the garbage falls from above the overflow cylinder 4 to the inside, passes below the overflow cylinder 4 from inside to outside, and rises outside. During the circulation, the garbage and the decomposing bacteria are stirred and mixed, and the garbage is decomposed. Therefore, it is possible to perform stirring and mixing by circulating garbage without using a screw or the like as in the related art. It should be noted that the garbage 1 is sufficiently above the upper rotating blades 6.
Even if 1 is inserted, the flow in the direction of the arrow is performed smoothly, so that no trouble occurs in the disassembling process.

The rotation of the upper rotating blades 6 also serves to move the garbage from the outside to the inside of the overflow cylinder 4. Therefore, when the upper rotary blade 6 is angled by an angle β with respect to the radiation direction as shown by a chain line in FIG. 4, the garbage can be more smoothly moved to the inside of the overflow cylinder 4. It is more effective to bend as shown by a broken line.

In order for the upper rotating blade 6 to pass over the horizontal support member 5 and cut fibrous garbage and the like, the upper rotating blade 6 is moved for the same reason as the angle α in FIG. It is better to have an angle β.

8 to 10 show the appearance of the garbage disposal apparatus according to the present invention. FIG. 8 is a plan view, FIG. 9 is a front view,
FIG. 10 is a left side view. On the upper front side of the cylindrical main body 1, there is a lid 12 for the garbage input port, and on the lower front side there is a take-out port 13 for the decomposed fertilizer.

Further, similarly to the garbage disposal apparatus proposed last time, a motor for rotationally driving the rotary shaft 7 is mounted on a ceiling plate covered on the main body 1 and is surrounded by a box 14. . Further, the air in the processing chamber 2 is suctioned, and the air is passed through the water to collect dust and to remove a bad smell.
Is installed.

[0023]

However, even with such an improved structure, various inconveniences have appeared during use. That is, the amount of the refuse to be treated in the garbage disposal chamber is small, and the stirring when the refuse to be treated does not reach the top end of the overflow cylinder is insufficient. Conversely, it is difficult to efficiently treat a large amount of refuse to be treated.

Further, since the rotating blades for crushing and agitating the refuse to be processed rotate in only one direction, there is a problem that the fibrous refuse to be entangled with the rotating shaft and the rotating blades. Further, there are problems that hard bones and rods cannot be reliably crushed, and that the exhaust gas from the garbage disposal room is not sufficiently deodorized, resulting in an unpleasant odor.

The technical problem of the present invention is to pay attention to such a problem, and it is possible to reliably stir even if the amount of the refuse to be treated is small, large, or large, and that the fibrous refuse to be treated is entangled. Therefore, it is an object of the present invention to realize a garbage disposal apparatus capable of reliably preventing hard garbage to be processed, reliably and efficiently pulverizing hard garbage, and sufficiently eliminating odors.

[0026]

The technical problem of the present invention is solved by the following means. Claim 1 is characterized in that one or a plurality of cutter members are fixed to the bottom of the processing chamber in a radial direction or at a certain angle, and an overflow cylinder is provided at a distance from the bottom of the processing chamber.

Thus, on the side wall of the overflow cylinder,
Since the window for passing the garbage to be treated is opened, even if the amount of garbage to be treated is small, the garbage to be treated can move from the outside of the overflow cylinder to the inside through the window hole. Even when the amount of dust is small, stirring and mixing can be performed reliably. When the amount of the refuse to be processed is large, the spill overflows inward from the upper end of the overflow cylinder and also flows inward from the window hole. Therefore, when the amount of the refuse to be processed is large, the mixture is more smoothly stirred and mixed. .

According to a second aspect of the present invention, the lower rotating blade according to the first aspect has a structure in which the lower rotating blade is rotated forward and backward, and the sectional shape of the lower rotating blade is suitable for rotation in both forward and reverse directions. The garbage disposal device has a mountain shape that is symmetrical to the front and rear.

As described above, the sectional shape of the lower rotating blade is

According to a third aspect of the present invention, the overflow cylinder is fixed by passing a horizontal support member between the upper end of the overflow cylinder according to the first or second aspect and the main body side wall of the processing apparatus. A horizontal upper rotating blade is disposed above the horizontal supporting member, and the upper rotating blade is configured to be driven to rotate forward and backward together with the lower rotating blade. The cross-sectional shape of the rotating blade is
This garbage disposal device has a mountain shape that is symmetrical in the longitudinal direction so as to be suitable for rotation in both forward and reverse directions.

As described above, the sectional shape of the upper rotating blade is also
Due to the symmetrical mountain shape, rotation in both the forward and reverse directions is performed smoothly, and the crushing operation is performed smoothly by overflowing from the upper end of the overflow cylinder and cooperative action with the support member.

According to a fourth aspect of the present invention, there is provided a garbage disposal apparatus in which the front and rear edges of the lower rotary blade and the upper rotary blade are formed in a saw-tooth shape. As described above, since the front and rear edges of the lower rotary blade and the upper rotary blade are formed in a saw-tooth shape, hard bones, tree branches, split chopsticks, and the like can be reliably cut and crushed without slipping.

According to a fifth aspect of the present invention, a vertical cutter member is provided on the lower rotary blade according to any one of the first to fourth aspects, the vertical cutter member having a cutting action with a side edge of the window hole. This is a fixed garbage disposal device.

Regardless of whether the amount of garbage to be treated is small or large, the garbage to be treated moves from the outside of the overflow cylinder to the inside through the window hole.
Since the vertical cutter member that performs a cutting action between the side edge of the window hole and the lower rotating blade is fixed upright, when the garbage to be processed passes through the window hole, the side edge of the window hole is vertically Disposable chopsticks, bones, etc. are reliably cut between the cutter member.

According to a sixth aspect of the present invention, an overflow cylinder fixed to a main body side wall of a processing apparatus by a horizontal support member is also provided above the upper rotating blade according to any one of the third to fifth aspects. A garbage disposal apparatus is provided, in which a vertical cutter member that cuts between the upper rotating blade and a side edge of a window hole of the upper overflow cylinder is provided upright and fixed to the upper rotating blade.

As described above, the overflow cylinder is also arranged above the upper rotating blade, and the vertical cutter which also has a cutting action between the upper rotating blade and the side edge of the window hole of the upper overflow cylinder. Since the members are upright and fixed,
The cutting mechanism by the window hole side edge and the vertical cutter member has at least a two-stage structure. As a result, the processing capacity is doubled and the size is increased, so that a larger amount of garbage can be processed.

A seventh aspect of the present invention is a deodorizing apparatus for a garbage disposal apparatus, wherein an overflow water tank is provided above a water surface of the main water tank in a closed main water tank, and the water in the main water tank is supplied to the above-mentioned water tank. It is structured to pump up to the overflow water tank. Further, in addition to the overflow weir of the overflow water tank, a slit formed on the bottom surface of the overflow water tank is provided. Further, one side of the overflow weir and the slit communicates with the intake cylinder from the garbage disposal chamber, and the other communicates with the exhaust cylinder to the outside.

As described above, in addition to the overflow weir of the overflow water tank, a slit formed on the bottom surface of the overflow water tank is provided, so that dust and odor sucked from the garbage disposal chamber via the intake cylinder can be removed. The water is formed in the main aquarium by a water curtain formed when the air passes through the slit or the slit, so that only the clean, low-odor air is exhausted from the exhaust pipe.

[0039]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a description will be given of an embodiment of how a garbage disposal apparatus and a deodorizing apparatus for a garbage disposal apparatus according to the present invention are actually embodied. FIG. 11 is a side view of the internal structure of the garbage disposal apparatus according to the present invention, and FIG.
It corresponds to. In the present invention, the same reference numerals as those of the conventional device indicate the same parts.

In the case of FIG. 1, if the amount of garbage does not exceed the height H of the overflow cylinder 4, the overflow operation was impossible and the stirring and mixing were insufficient. That is, when the amount of the garbage to be treated was small, the stirring and mixing were poor, and as a result, the fermentation treatment was insufficient.

However, in the case of the present invention, a window hole 4w is formed in the side wall of the overflow cylinder 4. This window hole 4w
Is suitably opened below the support member 5 of the overflow cylinder 4.

As described above, if the window hole 4w is opened in the side wall of the overflow cylinder 4, the amount of garbage to be processed is small, and even if the amount of garbage to be processed does not reach the upper end of the overflow cylinder 4,
When the height of the garbage 11 reaches the height of the window hole 4w, the garbage 11 raised by the rotation of the lower rotary blade 8 passes through the window hole 4w of the overflow tube 4 and overflows from the outside of the overflow tube 4 to the inside.

Then, below the overflow cylinder 4,
Due to the centrifugal force generated by the rotation of the lower rotating blade 8, the fluid flows from the inside of the overflow cylinder 4 to the outside. By repeating such an operation, the mixture is stirred and mixed by circulating as indicated by the arrow.

When the support member 5 is located above the garbage 11,
The uplift due to the rotation of the lower rotating blade 8 is obstructed, and as a result, the overflow operation from the upper end of the overflow cylinder 4 is hindered. Therefore, when the amount of garbage to be treated is large, overflow occurs at both the window hole 4w and the upper end of the overflow cylinder 4.
The stirring and mixing are performed more smoothly.

The illustrated support members 5 are arranged in a Y-shape at 120-degree intervals. And a support member 5 perpendicular to the paper surface.
Is represented by a sectional view. As is clear from this cross-sectional shape, the angle material 5a is fixed below the plate material 5p and is formed in an inverted regular triangle shape, thereby reducing the resistance when the garbage moves, and the stirring and mixing becomes smoother. To be done.

FIG. 12 is a sectional view taken along the line FF in FIG. 11, and corresponds to FIG. As is clear from this cross-sectional view, both the lower rotating blade 8 and the upper rotating blade 6 are formed with sawtooth shapes on both front and rear sides. In the case of the present invention, since both the lower rotating blade 8 and the upper rotating blade 6 rotate forward and backward, both front and rear sides are formed in a saw-tooth shape, and furthermore, they are symmetrical in the front and rear direction.

FIG. 13 is a sectional view taken along the line GG in FIG. 11, and corresponds to FIG. The lower rotating blade 8 is
An angle member 8a for reinforcement is welded and fixed on the horizontal blade plate 8p to form a mountain shape. And since it is formed in a symmetrical shape with respect to the center line C, the garbage can be pushed up and raised regardless of whether it rotates forward or backward.

Further, as shown in FIG. 12, since the serrated portions 8s are formed on both front and rear sides of the horizontal blade 8p, when the lower rotating blade 8 rotates, the serrated portions 8s are radially placed on the processing chamber bottom plate 3. Bones, tree branches, split chopsticks, and the like are sandwiched between the cutter member 9 fixed to the fin and the sawtooth-shaped portion 8s, and are cut finely.

In the saw-toothed portion 8s, a deep V-shaped portion and a shallow V-shaped portion are alternately formed, so that a thick branch or the like has a deep V-shaped portion.
It is cut at a V-shaped portion, and thin branches and the like are cut at a shallow V-shaped portion.

As described above, the saw-tooth shape makes it easy to cut a fibrous object. In addition, the bones and the like are caught by the jagged serrated portions 8s without slipping, are reliably cut, and are finely crushed while circulating many times.

As is clear from FIGS. 11 and 12, the upper rotating blades 6 are also formed in the shape of a mountain by reinforcing and fixing an angle member 6a on a horizontal blade plate 6p. Further, a saw-toothed portion 8s is formed before and after the horizontal blade plate 6p. Therefore, fibrous materials, bones, and the like are also cut and crushed between the serrated portion 6s of the upper rotating blade 6 and the horizontal plate portion 5p of the support member 5.

The upper rotating blade 6 is also connected to the lower rotating blade 8
Also, the root side to which the load is applied most is made thicker, and the tip side is made thinner.

As shown in FIG. 13, bones and split chopsticks that pass between the cutter member 9 and the sawtooth portion 8s on the processing chamber bottom plate 3 are cut, while bones that pass through other portions are cut. Will not be. On the other hand, in the embodiment of FIGS. 14 and 15, the vertical cutter members Lo and Li are arranged outside and inside the side wall of the overflow cylinder 4, and are fixed on the lower rotary blade 8 by welding. In addition, the lower rotating blades 8 are arranged in a cross shape at intervals of 90 degrees.

The outer vertical cutter member Lo of the overflow cylinder 4 has a slight gap with the outer wall surface of the overflow cylinder 4, and the inner vertical cutter member Li has a slight gap with the inner wall surface of the overflow cylinder 4. And are arranged respectively. The upper ends of the vertical cutter members Lo and Li are so high that they do not contact the upper horizontal support member 5.

Now, the lower rotating blades 8 are rotated, and garbage is drawn from the outside of the overflow cylinder 4 into the window hole 4w as shown by the arrow.
, When moving inward, the vertical cutter members Lo, Li also rotate together with the lower rotary blade 8, so that bones and split chopsticks are provided between the vertical cutter members Lo, Li and the side edges 4e of the window holes 4w. Is cut off.

Since the lower rotating blades 8 rotate back and forth at predetermined time intervals, the cutting of bones and the like is performed by the front and rear edges of the vertical cutter members Lo and Li and the front and rear side edges 4e of the window hole 4w. Will be Moreover, since the lower rotating blades 8 have four blades in a cross shape, the chance of cutting is further increased.

In this embodiment, the upper rotating blade 6 also has a four-blade structure in a cross shape. In this case, it is preferable that the upper rotating blade 6 and the lower rotating blade 8 are arranged so as to be shifted by 45 degrees so as not to overlap each other.

The embodiment shown in FIGS. 16 and 17 has a structure capable of coping with a large amount of processing. The vertical cutter members Lo and Li fixed on the lower rotary blade 8 as shown in FIG.
The stirring and cutting mechanism by the overflow cylinder 4 with the window hole 4w is stacked in a plurality of stages.

As shown in FIG. 16, the upper rotating blade 6 of FIG.
An overflow cylinder 4 fixed to the main body side wall of the processing apparatus by a horizontal support member 5 is also disposed above the upper side. Vertical cutter members Lo, Li which perform a cutting action between the upper rotating blade 6 and the side edge 4e of the window hole 4w of the upper overflow cylinder 4 are also fixed upright.

FIG. 17 is a sectional view taken along the line II in FIG. As is clear from this figure, it goes without saying that the upper rotating blades 6 corresponding to the upper rotating blades 6 in FIG. 11 are arranged in a cross shape on the upper horizontal supporting member 5.

With such a two-stage structure, the cutting of bones, split chopsticks and the like is also performed between the side edge 4e of the window hole 4w of the overflow cylinder 4 in the upper stage and the vertical cutter members Lo and Li in the upper stage. Is performed.

Moreover, the cutting is also performed between the upper horizontal support member 5 and the upper rotating blade 6 thereon.

Therefore, the processing capacity for stirring and mixing and cutting bones is doubled as compared with the structure of the embodiment shown in FIG. 14, and can be used for business use.

Although the illustrated embodiment has a two-stage structure, it goes without saying that a structure having three or more stages is also possible.

FIG. 18 shows an embodiment of a deodorizing apparatus according to the present invention, wherein (1) is a plan view, (2) is a JJ sectional view,
(3) is a right side view. Reference numeral 16 denotes a main water tank having a closed structure. Then, water is supplied into the main water tank 16 from the water supply port P1 on the upper right, and is stored up to the water surface L. When dirty, it is drained from drain ports P2 and P3 at the bottom.

An overflow water tank 17 is provided in a space above the water surface L. This overflow water tank 17
Has an overflow weir 18 and a guide plate 19 formed diagonally with the side wall lowered only at the tip. Therefore, the water pumped up by the submersible pump 20 through the water supply pipe 21 and accumulated in the overflow water tank 17 overflows from the overflow weir 18, flows out along the guide plate 19, and flows down in a curtain of water.

The bottom plate 22 of the overflow water tank 17
Has a slit 23 substantially parallel to the overflow weir 18.
Is open. Therefore, the water in the overflow water tank 17 flows down from the slit 23, and a curtain of water is formed. In other words, a double curtain is created.

The rear side wall 24 of the overflow water tank 17
Stands up to the ceiling wall 25 of the main aquarium 16. The front and rear side walls of both the main water tank 16 and the overflow water tank 17 are common. Therefore, the space above the main water tank 16 is divided into right and left by the water curtains W1, W2 and the rear side wall 24.

An intake duct 26 is arranged on the side of the overflow water tank 17 with respect to the rear side wall 24, and an exhaust duct 27 is connected on the opposite side. Therefore, the motor m is cooled by the cooling air sucked by the fan F1 from between the upper end of the motor box 14 and the upper lid 28 in FIG. Outside air is also taken in from the intake cylinder 31.

The odor and dust generated in the processing chamber 2 are transferred from the intake duct 26 at the upper part of the processing chamber 2 to the overflow water tank 1.
7 and then pass through the water curtains W1, W2. At this time, dust and odor are adsorbed into the water in the main water tank 16. Only the air thus cleaned is exhausted from the exhaust duct 27 to the outside air by the exhaust fan.

On the other hand, the floating substance floats on the water surface of the main water tank 16 and is discharged from the overflow port P4 at the time of overflow. In addition, a partition wall 29 rises from the bottom of the main water tank 16.

Since the partition wall 29 is provided between the water curtains W1, W2 and the submersible pump 20, the water curtains W1, W2
Most of the dust adsorbed into the water of the main water tank 16 together with the water precipitates on the left side of the partition wall 29.

Therefore, only clean water free of dust on the right side of the partition wall 29 is pumped up by the pump 20 and supplied to the overflow water tank 17.

When water is guided to the exhaust duct 27 by a pipe branched from the water supply pipe 21 and water is sprayed on the exhaust air, dust and odor can be more reliably removed. Further, it is preferable to provide the exhaust duct 27 with an odor adsorbent such as activated carbon.

A transparent tube 30 is connected to the outside of the main water tank 16 between the upper side and the lower side of the water surface, so that the water level can be checked from outside.

[0076]

According to the first aspect of the present invention, a window for passing the refuse to be processed is formed in the side wall of the overflow cylinder.
Even when the amount of garbage to be processed is small, the garbage to be processed can move from the outside of the overflow cylinder to the inside through the window hole, so that even when the amount of garbage to be processed is small, stirring and mixing can be performed reliably. If the amount of garbage to be treated is large, overflow from the upper end of the overflow cylinder to the inside,
Since it flows inward also from the window hole, even when the amount of refuse to be treated is large, the refuse is more smoothly stirred and mixed.

According to the second aspect, since the cross-sectional shape of the lower rotating blade is symmetrical in the front-rear direction so as to be suitable for rotation in both the forward and reverse directions, even when the lower rotating blade rotates forward, Even in the case of reverse rotation, the refuse to be processed can be surely raised and stirred and mixed.

According to the third aspect, since the cross-sectional shape of the upper rotary blade is also symmetrical in the longitudinal direction, the upper rotary blade is smoothly rotated in both the forward and reverse directions. The crushing operation is smoothly performed by the cooperative action with the above.

According to the fourth aspect, since the front and rear edges of the lower rotary blade and the upper rotary blade are formed in a saw-tooth shape, even hard bones, tree branches, split chopsticks, etc. can be cut without slipping. Can be crushed.

Regardless of whether the amount of garbage to be treated is small or large, the garbage to be treated moves from the outside of the overflow cylinder to the inside through the window hole.
Since the vertical cutter member that performs a cutting action between the side edge of the window hole and the lower rotating blade is fixed upright, when the garbage to be processed passes through the window hole, the side edge of the window hole is vertically Disposable chopsticks, bones, etc. are reliably cut between the cutter member.

According to a sixth aspect of the present invention, an overflow cylinder is provided above the upper rotating blade, and the upper rotating blade also has a cutting action with the side edge of the window hole of the upper overflow cylinder. Since the vertical cutter member to be cut is set up and fixed, the cutting mechanism by the side edge of the window hole and the vertical cutter member has a two-story structure. As a result, the processing capacity doubles,
In addition, it becomes large and can process a larger amount of garbage.

According to the deodorizing device of the present invention, in addition to the overflow weir of the overflow water tank, the bottom of the overflow water tank has a slit. Is adsorbed in the main tank by a water curtain formed when passing through an overflow weir or a slit, so that only clean and low-odor air is exhausted from the exhaust pipe.
