Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a partition plate provided in a fermenter tank of a garbage disposal apparatus for converting garbage discharged from a home kitchen or the like into a compost by fermentation decomposition.

[0002]

2. Description of the Related Art Conventional garbage fermentation / decomposition technology for household use is known in the art, and garbage and fermentation bacteria are put into a container and stirred to promote fermentation and remove water.
The waste was reduced and composted while undergoing fermentation and decomposition treatment. Raw garbage was further added thereto, and the mixture was repeatedly stirred and fermented, collected as compost, and used as fertilizer for home gardens and the like. In this type of garbage disposer, the periphery of a fermenter serving as a container is covered with an outer frame, and a stirring claw shaft is inserted horizontally in the upper, lower, left, and right central portions of the fermentation tank, and is horizontally laid. When a nail is planted and rotated in the fermenter to stir it, and aerobic bacteria and moisture regulators that promote fermentation are added to the fermenter together with the garbage, the garbage is crushed. The garbage was further decomposed by the bacteria while being stirred while being added thereto, and the added garbage was further decomposed. The treated compost overflowed from one end of the fermenter and was collected as compost on a tray or the like.

[0003]

However, if the fermentation tank in the conventional garbage disposal machine is a single tank, it is not possible to separate the processed material subjected to the decomposition and fermentation treatment from the garbage.
Although it is desired to partition into a plurality of tanks, it is difficult to partition up and down because a stirring claw shaft is laid across the center of the fermentation tank, and this stirring claw shaft is an obstacle. In addition, since the stirring is performed by rotating the stirring claw shaft, the processed material in the fermenter flows and pushes the partition plate, and a plate material having strength enough to withstand the pressure is required. In order to withstand this, the thickness of the plate is increased, and the weight is increased.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a stirring claw shaft in which a plurality of stirring claws are planted in the center of a fermenter for fermenting garbage. In a household garbage disposer that performs fermentation decomposition treatment while stirring the processed material in the fermentation tank, the partition wall is formed in a direction perpendicular to the stirring claw axis, and the fermentation tank is divided into a plurality of tanks. The partition wall is vertically divided at the position of the stirring claw shaft, and the upper partition wall is made detachable. Further, the lower partition wall located below the upper partition wall is formed integrally with the fermenter, and the upper partition wall is provided with a concentric rib centered on a stirring claw shaft. In addition, a stirring claw shaft in which a plurality of stirring claws are planted in the center of a fermenter for fermenting garbage is horizontally laid, and the fermentation decomposition treatment is performed while stirring the processed material in the fermenter. In a household garbage disposer, a partition wall is formed in a direction perpendicular to the agitating claw axis, the partition wall is divided into an upper partition wall and a lower partition wall, and the upper partition wall is engaged with upper ends thereof. A projection is provided, and an engagement hole for inserting and engaging the engagement projection is provided on a side surface of the fermenter.

Further, the side surfaces of the support stands 56 are engaged and fixed by left and right side walls 10e and 10f, a front wall 10b and a rear wall 10c. Further, a processed material discharge port 13 is opened at a lower portion of the front wall 10b so that the collection tray 29 can be pulled out from the processed material discharge port 13.

Next, the configuration of the fermenter 1 will be described. As shown in FIGS. 3 and 4, the fermenter 1 is formed in a U-shape in a side view, and a stirring claw shaft 19 is inserted in the center of the lower semicircular portion in the left-right direction. Claw 17 on stirring claw shaft 19
Are planted at predetermined intervals and shifted by a predetermined angle, and the bottom of the fermenter 1 is located at the lower and outer position of the rotation trajectory of the claw 17, 18. The shapes of the two are substantially matched so that the stirring is sufficiently spread. The agitating claw shaft 19 is driven by the power of a motor 43 disposed below the right side of the fermenter 1. The output shaft 43a of the motor 43 is penetrated through the support stand 56 and protrudes rightward. The drive sprocket 40 is attached to the end of the output shaft 43a. A driven sprocket 41 is fixed to the right end of the stirring claw shaft 19, and a chain 42 is wound between the driving sprocket 40 and the driven sprocket 41 so that power can be transmitted. The garbage is stirred and further crushed by the claws 17, 18, 18,...

The fermenter 1 is configured to be rotatable around a stirring claw shaft 19. As shown in FIG.
In the fermenter 1, bearings 30, 30 ′ are fixedly provided at the center of a semicircular portion at the lower part of the side surface having a U-shape in side view. Each of the bosses of the bearings 30 and 30 ′ is formed in a circular shape having the same axis as the agitating claw shaft 19 supported inside, and the outer peripheral surface of the boss portion is provided in a pivot support hole 56 b provided on the upper part of the support stand 56.
It is freely rotatably fitted inside. Therefore, the fermenter 1 is rotatable about the stirring claw shaft 19,
3, the front wall 10b is removed, and as shown by the two-dot chain line in FIG. 3, the front wall 10b is rotated forward and downward so that the processing object inside can be smoothly discharged from the charging port 1e, thereby facilitating cleaning and maintenance. Like that.

The upper part of the fermenter 1 is substantially cubic and its upper part is opened to form an inlet 1e. The inlet 1e is closed by the inlet lid 12. As shown in FIG. 4, the inside of the fermenter 1 is divided in the front-rear direction perpendicular to the stirring claw shaft 19, and the first partition wall 2 and the second partition wall 3 are separated.
Is arranged. The space between the first partition 2 and the right side plate of the fermenter 1 is a charging tank 1a, the space between the first partition 2 and the second partition 3 is a processing tank 1b, and the left side of the fermenter 1 The space between the plate and the second partition wall 3 is formed as a discharge tank 1c.

Further, as shown in FIG.
A substantially rectangular overflow hole 2c is opened at the upper front side, and a rectangular overflow hole 3c long forward and backward is opened just above the stirring claw shaft 19 in the middle part of the second partition wall 3, as shown in FIG. The input tank 1a and the processing tank 1b are communicated with each other, and the processing tank 1b and the discharge tank 1c are communicated with each other. It overflows to the discharge tank 1c. A dam plate 58 is disposed below the overflow hole 2c so as to be vertically movable, and the height of the lower portion of the overflow hole 2c, that is, the overflow height is adjustable.

As shown in FIG. 4, a planar heater 37 covered with a heat insulating material as a heating means is provided on the right side of the outer peripheral surface of the lower part of the fermenter tank 1, that is, on the outer peripheral surface of the lower part of the input tank 1a. The heater 37 is provided so that the temperature can be adjusted by a control unit (not shown).
The processed material in a is heated to promote fermentation.

As shown in FIGS. 3 and 7, an exhaust port 1d is opened at the upper part of the right side of the fermenter 1 (that is, at the upper part of the side of the input tank 1a). Tank 1
A deodorizing section 20 is disposed on the side surface, and an exhaust fan 21 is disposed above the deodorizing section 20 to suck dust and gas generated by fermentation in the fermentation tank 1 (particularly, the charging tank 1a). The sucked gas or the like is sent into the thermal catalyst 22 disposed on the right side of the fermenter 1 and decomposes the odor in the gas.
Through which the heat of the exhaust gas is radiated and exhausted to the outside of the garbage disposal machine 9 through an opening provided in the bottom 10d.

The processed material pulverized, fermented and decomposed in the charging tank 1a overflows to the processing tank 1b through the overflow hole 2c. This processing tank 1
Since no garbage is put into b, the processed material is decomposed as it is stirred, and is dried and composted. In the processing tank 1b, a stirring feed claw 17 having a large function of sending the processed material to the discharge side is planted on the stirring claw shaft 19, and the composted processed material can be smoothly passed through the overflow hole 3c. The processing material is sent to the discharge tank 1c to prevent a large amount of processed material from being deposited in the processing tank 1b.

Further, on the lower surface of the processing tank 1b and the lower surface of the discharge tank 1c, drop openings 1f, 1f,
.. is open. The falling port 1 on the lower surface of the discharge tank 1c

Next, the configuration of the first partition wall 2 and the second partition wall 3 will be described. The outer peripheral shapes of the first partition wall 2 and the second partition wall 3 are substantially the same, and as shown in FIGS. 6 and 7, the lower partition walls 2a and 3a and the upper partition walls 2b and 3b The partition walls 2a and 3a are integrally erected from the lower inner peripheral surface of the fermenter 1 in a semicircular shape so that the lower partition walls 2a and 3a are formed together with the fermenter 1 by injection molding or the like. The height of the upper end sides of the lower partition walls 2a and 3a is located slightly below the stirring claw shaft 19. Upper partition walls 2b and 3b are detachably mounted on the upper portions of the lower partition walls 2a and 3a. The overflow holes 2c and 3c are opened in the upper partition walls 2b and 3b, respectively. The agitating claw shaft 19 is detached after the upper partition walls 2b and 3b are removed upward and the upper part is opened as shown in FIG.

The upper partition walls 2b and 3b are configured to be easily attached to the front and rear side surfaces of the fermenter 1 with a non-tool without using fastening parts such as bolts. Since the upper partition walls 2b and 3b have substantially the same engagement and mounting structure, the description will be made using the upper partition wall 2b. That is, FIGS.
As shown in the figure, a locking piece is formed on the lower side of the upper partition wall 2b. The locking piece is a fixed locking piece 2d protruding rightward and downward at a fixed length, and is opposite to the lower left. The left and right locking pieces 2d and 2e are alternately protruded left and right, and a recess is formed between the left and right locking pieces 2e when viewed from the front, and the upper side of the lower partition wall 2a is inserted and engaged. I can do it. However, a configuration in which a concave portion is formed in part may be adopted. By alternately providing the right locking pieces 2d and the left locking pieces 2e in this manner, molding is facilitated and manufacturing costs are reduced.

Engagement protrusions 2f are formed at the front and rear ends of the upper partition wall 2b. As shown in FIGS. 6, 9, and 10, the engagement protrusion 2f is formed in an L shape in plan view, and the portion of the engagement protrusion 2f is configured to protrude from the fermenter 1. That is, the upper partition wall 2b

As shown in FIGS. 8 to 10, an engagement hole for inserting and locking the engagement protrusions 2 f is provided in the upper part of the front and rear surfaces of the fermenter 1. The engagement hole comprises an insertion hole 1g slightly larger than the engagement protrusion 2f and a slot 1e opened substantially the same as the thickness of the upper partition wall 2b, and the slot 1e is continuous with a lower portion of the insertion hole 1g. When the engaging pieces 2d and 2e of the upper partition wall 2b are engaged with the lower partition wall 2a, the engaging projections 2f are located in the slots 1e.

Similarly, at the lower part of the upper partition wall 3b, as shown in FIGS.
d and 3e are formed, and engaging projections 3f and 3f are formed on the front and rear ends of the upper partition wall 3b, respectively. Insertion holes 1g and 1g are opened at the positions where the second partition walls 3 are arranged on the front and rear surfaces of the fermenter 1, and slots 1e and 1 are formed below the insertion holes 1g and 1g.
e is formed.

Therefore, in order to fix the upper partition walls 2b and 3b, first, after the stirring claw shaft 19 is mounted on the fermenter 1, the lower portions of the upper partition walls 2b and 3b are respectively connected to the lower partition walls 2a and 3b.
a. The engaging projections 2f, 2f and 3f, 3f on the upper parts of the upper partition walls 2b, 3b
g · 1 g is penetrated and held. At this time, the upper partition 2b
, And 3b are located above a predetermined position, and the lower left and right locking pieces 2d, 2e, and 3d, 3e are located immediately above the upper ends of the lower partition walls 2a and 3a, respectively. The upper partition walls 2b and 3b are arranged so that the edges of the engagement projections 2f and 2f and 3f and 3f are along the slots 1e and 1e.
Are guided downward, the locking pieces 2d, 2e, and 3d.
The upper portions of the lower partition walls 2a and 3a are inserted into the recesses formed by 3e, respectively, and the lower portions of the upper partition walls 2b and 3b are engaged immovably left and right. At this time, the front and rear engagement projections 2f, 2f and 3f, 3f on the upper portions of the lower partition walls 2a, 3a.
The front and rear surfaces of the fermenter 1 are fitted between them, and the partition walls 2b and 3b are securely fixed.

The engaging projections 2f and 3f provided at the front and rear ends of the upper partition walls 2b and 3b are not limited to the L-shape in plan view, but may be formed into a T-shape as shown in FIG. Can also obtain the same retaining effect.

With such an engagement configuration, the first partition plate 2 and the second partition plate 3 are divided into upper and lower parts, and the stirring pawl shaft 19
Can be assembled from inside the fermenter 1, the upper partition walls 2b and 3b can be fixed without using fastening parts such as bolts and tools, and a configuration that is easy to attach and detach and excellent in maintainability can be achieved.

Further, as shown in FIG. 4, the side surfaces of the upper partition wall 2b have ribs 2g and 2g which are curved in a semicircular shape in cross section.
The ribs 2g and 2g 'are formed in a concentric arc shape centered on the stirring claw shaft 19 as shown in FIG.

The upper partition wall 2b is formed by the ribs 2g.
Is increased, the rigidity is increased, and it is possible to withstand the pressure received from the flow of the processing object caused by rotating the stirring claw shaft 19. In addition, the rib 2g
2g 'is formed concentrically around the agitating claw shaft 19, so that it is matched with the flow of the agitated material by the agitating claws 18, 18 ...
2g ', and the agitated material does not hit the ribs 2g and 2g' to push up the upper partition 2b, so that the upper partition 2b does not come off. Further, in order to increase the section modulus of the upper partition wall 2b, the upper partition wall 2b may be formed in a wavy cross section. However, as compared with the configuration, the ribs 2g and 2g 'which are curved in a semicircular shape are more processed. It is difficult to adhere.

In this embodiment, two ribs 2g and 2
Although g ′ is formed, the number is not limited and a plurality of g ′ may be formed to further increase the rigidity.

As described above, the first partition wall 2 and the second partition wall 3

[0029]

The present invention is configured as described above.
The following effects are obtained. That is, as described in claim 1, a stirring claw shaft in which a plurality of stirring claws are planted in the center of a fermenter for fermenting garbage is horizontally laid, and the processed product in the fermenter is fertilized. In a household garbage disposer that performs fermentation decomposition while stirring, a partition wall is formed at right angles to the stirring claw axis to partition the fermenter into a plurality of tanks, and the partition wall is positioned at the stirring claw axis position. Since the upper partition is divided vertically and the upper partition is removable, the agitator claw shaft can be removed from the fermenter by removing the upper partition wall. Maintenance can be performed more easily than removal, and the partition wall is divided into upper and lower parts. It is possible to improve the performance.

In addition, since the lower partition located below the upper partition is integrally formed with the fermenter, the lower partition can be manufactured at the same time as the fermenter is manufactured. Therefore, the manufacturing cost can be reduced and the number of parts can be reduced.

Further, since the upper partition wall is provided with a concentric rib centered on the agitating claw shaft, the rigidity of the partition wall can be increased with a simple configuration.
In addition, the processed material in the fermenter flows due to the rotation of the stirring claw, and can withstand the pressure due to the flow. Therefore, the thickness is not increased, the cost is low, and a lightweight partition plate is sufficient. Further, by forming the ribs concentrically around the agitating claw axis, the processed material agitated by the agitating claw flows along the ribs even if it hits the upper partition wall, so that the upper partition wall is pushed up. Thus, there is no problem such as the upper partition coming off.

Further, a stirring claw shaft having a plurality of stirring claws planted in the center of the fermenter for fermenting garbage is horizontally laid horizontally in the fermenter. In a household garbage disposer that performs a fermentation decomposition treatment while stirring the processed material, a partition wall is formed in a direction perpendicular to the stirring claw axis, and the partition wall is divided into an upper partition wall and a lower partition wall, Engagement projections are provided on both upper end portions of the upper partition wall, and on the other hand, engagement holes for inserting and engaging the engagement projections are provided on the side surfaces of the fermenter, without using fastening parts such as bolts or tools. The upper partition wall can be attached and detached, and can be easily assembled by only the operation of engaging the engagement projection with the engagement hole.
