Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage disposal apparatus for decomposing garbage.

[0002]

2. Description of the Related Art As a prior art, Japanese Patent Application Laid-Open No. 11-3352 is disclosed.
There is a garbage disposal device disclosed in Japanese Patent Publication No. 1 (JP-A) No. This garbage processing apparatus decomposes garbage put into a garbage processing tank while stirring the garbage together with the garbage processing material by a stirring means, and a garbage processing material ( An opening for overflowing the remaining waste is provided.

[0003] Thus, when the bulk (top height) of the garbage processing material increases in the garbage processing tank, excess garbage processing material overflows from the opening with the rotation of the stirring means, It can be collected in an adjacent collection box via a partition plate.

[0004]

However, in the above-mentioned garbage processing apparatus, when the amount of garbage to be put into the garbage processing tank is large, the volume of the garbage processing material immediately below the input port increases. However, there is a problem that the amount of garbage that can be input is limited. Further, there is a possibility that the stirring is not performed properly and the decomposition of the garbage by the microorganisms is not performed properly.

The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object to provide a garbage processing apparatus capable of sufficiently securing a space for introducing garbage in a processing tank. Aim.

[0006]

In order to achieve the above object, according to the first aspect of the present invention, the second stirring blade adjacent to the first stirring blade provided on the food waste inlet side of the stirring blade is provided with a second stirring blade. 1
The stirring blades were mounted at intervals corresponding to 50 to 60% of the blade length L1.

In the invention according to claim 2, the first and second stirring blades push the garbage disposal material toward the collection box when the first and second stirring blades rotate in a predetermined rotation direction. The extrusion surface was inclined with respect to the axial direction of the rotating shaft.

[0008] Thus, the ability of conveying the garbage disposal material is enhanced by the cooperation of the first stirring blade and the second stirring blade, and the garbage disposal material is efficiently sent to the inner side of the decomposition chamber (toward the drying chamber). Thus, the bulk (upper surface height) of the garbage disposal material is reduced near the lower part of the input port, and a large space for inputting the garbage can be obtained.

According to the third aspect of the present invention, a third stirring blade is provided on the side of the second stirring blade which is remote from the garbage inlet, and the third stirring blade is 110 to 120% of the blade length L2 of the second stirring blade. It was installed at an interval corresponding to.

[0010] Thus, in the space on the back side (close to the drying chamber) of the decomposition chamber into which the garbage disposal material has been sent, the third stirring blade is attached at a distance that can be stirred by the second stirring blade. It is possible to efficiently arrange the stirring blades without creating a portion that is not performed.

[0011] In the invention according to claim 4, the installation position of the garbage input port is provided on the side where the stirring blade performs the descending operation in the garbage processing tank.

[0012] This is because, in the case of stirring having a rotating shaft in the horizontal direction as in the present invention, the bulk of the garbage disposal material becomes higher on the rising side (lifting side) of the stirring blade than the center of the rotating shaft, and Since the bulk of the garbage disposal material is lower on the lower side (push side) of the stirring blade, the garbage input port is provided on the lower side, so that a large garbage input space can be taken.

According to the fifth aspect of the present invention, the position of the garbage inlet is set to a position corresponding to 50 to 60% of the blade length L2 of the second stirring blade between the second stirring blade and the third stirring blade. To the end of the garbage treatment tank near the first stirring blade.

This is also possible by setting the garbage inlet in the axial direction of the garbage inlet in accordance with the range in which the garbage disposal material is depressed by the first and second stirring blades. Large space for food waste can be taken.

In the invention according to claim 6, the inclination angle of the extruding surface of the stirring blade is set to 30 to 60 degrees.

Thus, the efficiency of the stirring blade is improved, and a wide range of garbage disposal materials can be stirred and mixed with one stirring blade.

In the invention according to claim 7, the control device detects that the bulk of the garbage disposal material in the garbage disposal tank exceeds a predetermined range, and determines the transfer amount to the outside of the garbage disposal tank. The rotation frequency of the stirring means was increased so as to increase the number.

In the invention according to claim 8, the control device detects that the bulk of the garbage disposal material in the garbage disposal tank exceeds a predetermined range, and determines that the bulk is within the predetermined range. Control so that the amount of garbage to be introduced is limited.

Thus, the bulk of the garbage disposal material in the treatment tank is kept within a certain range, and the decomposition of the garbage by microorganisms is stabilized.

[0020]

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a sectional view showing the internal structure of the garbage processing apparatus.

As shown in FIG. 1, a garbage processing apparatus 1 according to the present embodiment is installed below a kitchen sink 2, and is provided with a garbage processing tank 3 for decomposing garbage and a garbage processing tank. Collection box 4 for collecting residue W generated in tank 3 (remaining waste generated by decomposition of garbage).
And a ventilation fan (or suction pump) 5 for ventilating the inside of the collection box 4 and the garbage disposal tank 3.

A drainer 2a of the kitchen sink 2 is provided with a detachable strainer 6 made of perforated metal, wire mesh, or the like, so that the garbage can be temporarily stored in the strainer 6. The tap water used in the kitchen sink 2 and the water flowing out of the garbage collected in the strainer 6 flow out to the drain tank 7 through the small hole of the strainer 6, and further drain from the drain tank 7 with the drain trap 8a. Through the sewer.

The garbage disposal tank 3 is provided with a garbage inlet 9 opened at the lower part of the strainer 6 and a gate 10 for opening and closing the garbage inlet 9. The gate 10 is connected to the foot pedal 11 via a link mechanism or the like (not shown),
Depressing the foot petal 11 can open the garbage inlet 9.

The garbage disposal tank 3 is provided with a microorganism carrier 12 in which microorganisms (aerobic bacteria that can withstand high temperatures) are carried on woody chips.
Decomposition chamber 13 containing (so-called garbage disposal material)
And the residue W after the garbage is decomposed in the decomposition chamber 13
And a drying chamber 14 for drying the water. The decomposition chamber 13 and the drying chamber 14 are provided adjacent to each other with a partition plate 15 therebetween and communicate with each other through an overflow port 33 opened to the partition plate 15.

The garbage processing tank 3 is provided with a stirring means (described later) for stirring the inside of the decomposition chamber 13 and the drying chamber 14.
And a moisture sensor 16 for measuring the amount of moisture (moisture content) contained in the microorganism carrier 12 in the decomposition chamber 13.

FIG. 2A is a perspective view showing a garbage treatment tank and a collection box according to an embodiment of the present invention, and FIG. 2B is an explanatory view showing a stirring state of a residue in a drying chamber. As shown in FIG. 2, the stirring means is configured by attaching a plurality of stirring blades 18 (18a, 18b, 18c, 18d) to a rotating shaft 17.

Each stirring blade (18a, 18b, 18c, 18
The blade length d) is determined by the relationship between the rotating shaft 17 and the bottom and upper space of the garbage disposal tank 3, but here, the blade lengths are substantially the same.

The rotating shaft 17 is disposed in the decomposition chamber 1 of the garbage disposal tank 3.
3 and the drying chamber 14 are provided therethrough, and are rotationally driven by a motor 19 arranged outside the decomposition chamber 13. In addition,
The bottom surfaces of the decomposition chamber 13 and the drying chamber 14 are curved in a semi-cylindrical shape along the rotation orbit of the stirring blade 18.

The operation of the motor 19 is controlled by the control device 20. During normal operation, the motor 19 rotates only in one direction (right rotation in FIG. 3).

The collection box 4 is detachably mounted adjacent to the outside of the drying chamber 14 and communicates with the drying chamber 14 through an overflow port 21 opened on the side of the drying chamber 14.

The overflow port 21 is offset in the counter rotating direction of the stirring blade 18 when the stirring blade 18 comes directly above the rotation shaft 17 on the side surface of the drying chamber 14 above the mounting position of the rotation shaft 17. Position, ie Figure 2
As shown in (b), it is open at a position separated by a predetermined distance to the left (in the anti-rotation direction) from directly above the rotation shaft 17.

A ventilation port 22 for introducing outside air into the collection box 4 is provided at the upper side of the collection box 4.
Are formed.

The ventilation fan 5 is connected to an intake pipe 23 leading to the inside of the garbage disposal tank 3 and an exhaust pipe 24 leading to an external exhaust passage (not shown). The air sucked from inside 3 is discharged to an exhaust passage via an exhaust pipe 24.

Since the garbage disposal tank 3 and the collection box 4 communicate with each other through the overflow port 21, when the ventilation fan 5 rotates, the ventilation port 22 formed in the collection box 4 serves as an air intake. The inside of the collection box 4 and the inside of the garbage disposal tank 3 can be ventilated.

In the middle of the exhaust pipe 24, a deodorizer 25 for removing the odor generated in the garbage disposal tank 3 is provided.

Next, the operation of the garbage processing apparatus 1 will be described.

When the garbage is put into the decomposition chamber 13 of the garbage disposal tank 3, the stirring blades 18 rotate to mix the garbage with the microorganism carrier (garbage disposal material) 12 with stirring. At this time, the garbage is decomposed by the action of microorganisms carried on the garbage disposal material 12, and harmless decomposed gas and decomposed water are generated. This decomposed water is evaporated and exhausted to the outside together with the decomposed gas.
It is not flushed down the drain.

Residue W generated by decomposition of garbage
The drying chamber 1 is gradually moved from the decomposition chamber 13 through the overflow port 33 of the partition plate 15 by the rotation of the stirring blade 18c.
4 and dried in the drying chamber 14.

The residue W dried in the drying chamber 14 is shown in FIG.
As shown in (b), the liquid is lifted by the rotation of the stirring blade 18d, and is collected in the collection box 4 as much as overflows from the overflow port 21.

Next, the gist of the present invention will be described.

FIGS. 3A and 3B are views showing a state where the stirring blade 18 is attached to the rotating shaft 17. FIG. 3A is a schematic plan view.
(B) is a schematic sectional view seen along ABCD in (a).

FIG. 4 is a graph showing the stirring range of the garbage disposal material 12 by changing the mounting angle α of the stirring blade 18 with respect to the rotating shaft 17 in FIG.

Lh is the distance from the point C on the rotating shaft 17 corresponding to the peak D of the garbage disposal material 12 lifted by the stirring blade 18 to the stirring blade 18, and this distance L
h is the transport distance for sending the garbage processing material 12 to the back.

Lw is calculated from the foot E on the far side of the mountain of the garbage disposal material 12 lifted by the stirring blade 18
And a stirring distance within a range in which the garbage processing material 12 can be moved.

From the results, as shown in FIG. 4, the transport distance Lh and the stirring distance Lw are the maximum around 45 degrees, and from the viewpoint that the longer the transport distance or the stirring distance is, the more efficient the installation of the stirring blade 18 to the rotary shaft 17 is. The angle α is 30 to 60 degrees, desirably 40 to 50 degrees, and more desirably 44 to 46 degrees. By attaching the stirring blade 18 at this angle, a wide range of the garbage disposal material 12 can be efficiently stirred and mixed. it can.

However, the third stirring blade 18c and the fourth stirring blade 18
In d, under conditions that do not require a particularly large transfer capacity, the condition is not limited to 30 to 60 degrees, and any condition can be used as long as stirring can be performed.

FIG. 5 shows the first and second stirring blades when the mounting angle α of the first and second stirring blades 18a and 18b is 45 degrees.
Garbage treatment material 1 by changing the length L of the stirring blades 18a, 18b
2 is a graph showing the stirring range of No. 2;

As a result, both the transfer distance Lh and the stirring distance Lw are substantially proportional to the blade length L of the stirring blade 18, the transfer distance Lh is 50 to 60% of the blade length L, and the stirring distance Lw is the blade length L. Of 1
This is a value corresponding to 10 to 120%.

The transport distance Lh and the stirring distance Lw are slightly shortened when the mounting angle α of the first and second stirring blades 18a and 18b is changed from 30 degrees to 60 degrees, but the garbage in the garbage processing tank 3 is reduced. As the bulk (upper surface height) distribution of the processing material 12, it is desirable from the viewpoint of garbage processing efficiency that the lower side of the input port 9 is made lower and becomes higher toward the drying chamber 14 side.

Therefore, it is desirable that the transport distance Lh and the stirring distance Lw be within the above ranges even when the mounting angle α is changed, and the following settings are made using these values.

FIG. 6A is a schematic front view showing the setting position of each stirring blade 18 and the installation position of the charging port 9, and FIG. 6B is a schematic side view.

In order to reduce the bulk (height of the top surface) of the garbage disposal material 12 and increase the garbage input space below the input port 9, the first stirring blade 18a and the second stirring blade 18b are linked. In order to increase the transfer capacity of the garbage processing material 12, the blade length L1 corresponding to the transfer distance Lh of the first stirring blade 18a is set to 5
The second stirring blade 18b is set at a position of 0 to 60%.

That is, the first stirring blade 18a and the second stirring blade 1
The distance L3 between 8b is L3 = 0.5 to 0.6 × LI.

As a result, the next second stirring blade is attached to the top of the mountain of the garbage disposal material 12 transported by the first agitating blade 18a, and the garbage disposal material 12 is most efficiently placed on the inner side of the decomposition chamber 13 ( By being sent to the drying chamber 14), the bulk (upper surface height) of the garbage processing material 12 is reduced near the lower part of the input port 9, and a large garbage input space can be taken.

In the space on the inner side of the decomposition chamber 13 into which the garbage disposal material 12 is fed (close to the drying chamber 14), the second stirring blade 18b The third stirring blade 18c is set at a position of 110 to 120% of the blade length L2 corresponding to the stirring distance Lw in the above. That is, the second stirring blade 18b and the third stirring blade 1
The distance L4 between 8c is L4 = 1.1 to 1.2 × L2.

Thus, since the next third stirring blade is mounted at a distance that can be stirred by the second stirring blade, the stirring blade can be efficiently arranged without making a portion that is not stirred.

The position of the garbage inlet 9 is set on the side where the stirring wing 18 moves downward, because the bulk of the garbage disposal material 12 is reduced because the garbage input space 30 is required to be large.

Further, in the axial direction of the rotary shaft 17, the second stirring blade 18b and the third stirring blade 18b are pushed in by the first stirring blade 18a and the second stirring blade 18b in accordance with the range where the garbage disposal material 12 is depressed. It is provided in a range from a position corresponding to 50 to 60% of the blade length L2 corresponding to the transport distance Lh in the second stirring blade 18b between the stirring blade 18c and the processing tank end near the first stirring blade 18a.

That is, in FIG. 6A, the second stirring blade 1
The distance L5 from 8b to the left end of the inlet setting range M is L
5 = 0.5 to 0.6 × L2.

As a result, the garbage disposal material 12
The space in the disassembly chamber 13 can be used effectively by setting the garbage into the garbage input space 30 and setting the garbage input port 9 in accordance with the dent.

However, preferably, the food waste inlet 9 is provided near the wall on the side of the first stirring blade 18a so that the food waste
It is desirable that the disassembling process be performed more sufficiently while being transported from one end to another.

A sprocket 31 is integrally attached to the end of the rotating shaft 17 so that the rotating force of the motor 19 is transmitted through a chain 32 and the rotating shaft 17 rotates.

(Second Embodiment) A control operation for detecting the bulk (upper surface height) of the garbage disposal material 12 in the decomposition chamber 13 and maintaining the garbage disposal material 12 at an appropriate amount will be described with reference to a flowchart shown in FIG. This control operation is performed by the control device 20 shown in FIG.
Are contents which are appropriately determined and instructed based on various input signals.

When the bulk (upper surface height) detection circuit of the garbage disposal material 12 is turned on (step S1), first, a count counter i in the circuit is set to 1 (step S2). Next, a bulk level sensor 2 for detecting the bulk of the garbage processing material 12
6 is not in the ON state (Step S)
3).

Normally, if the bulk of the garbage disposal material 12 is within an appropriate range, the bulk level sensor 26 is not turned on, and the stirring motor 19 is turned on for a minute (in this case, one minute) as a normal stirring operation.
Then, the operation of turning off for 15 minutes (step S4) is repeated.

However, if the bulk of the garbage disposal material 12 is increased due to the input of garbage or the like and exceeds the appropriate range, the bulk level sensor 26 comes into contact with the garbage disposal material 12 and turns on. When the ON state is detected, 1 is added to the number of the counter i (step S5), a timer for measuring one day is started (step S6), and the stirring operation at the time of level over is performed for i minutes (in this case, i). (= 1 + 1 = 2 minutes) The operation of turning on the stirring motor 19 and turning it off for 15 minutes (step S7) is repeated.

When one day has passed by the timer (step S
In step 8), it is determined whether the number of the counter i is 3 (step S9). If not yet, the flow returns to step S3 to determine whether or not the bulk level sensor 26 is in the ON state.

As described above, even if the stirring operation is repeated for one day with the ON time of the stirring motor 19 extended by one minute as the stirring operation at the time of level over, the garbage disposal material 12 from the decomposition chamber 13 to the drying chamber 14 For example, when the amount exceeding the discharge amount is input, the ON state of the bulk level sensor 26 due to the garbage disposal material 12 in the decomposition chamber 13 is not canceled, and as a stirring operation at the time of level over again, the counting counter i 1 is further added to the number (step S5), the timer for measuring one day is restarted (step S6), and the stirring motor 19 is activated for i minutes (in this case, i = 2 + 1 = 3 minutes) as the stirring operation when the level is exceeded. The operation of turning on and turning off for 15 minutes (step S7) is repeated.

When one day has passed by the timer (step S
In step 8), it is determined whether or not the number of the count counter i is 3 (step S9). If the number is 3 (level over is detected for two consecutive days), the user is refrained from inputting. The warning LED is lit on the foot pedal 11 (step S10), and the process returns to the initial step S2.

If the level over is detected even after the warning is issued, the ON time of the stirring motor 19 is extended by one minute as the stirring operation at the time of the level over again, and the stirring for one day is repeated. When the bulk of the processing material 12 is in an appropriate range and the bulk level sensor 26 is not turned on, the stirring motor 19 is turned on for i minutes at that point in time and turned on for 15 minutes.
Warning LED after performing FF operation (step S4)
Is turned off (step S11) and the process returns to the initial step S2.

As a result, the bulk of the garbage disposal material in the treatment tank is kept within a certain range, and the decomposition of the garbage by microorganisms is stabilized.

(Modification) In the garbage processing apparatus 1 described above, the decomposition chamber 13 and the drying chamber 14 are formed in the garbage processing tank 3, but the decomposition chamber 13 and the drying chamber 14 are not necessarily formed separately. It is not necessary to perform the process, and it may be configured as one decomposition chamber 13.

In the garbage processing apparatus 1 described in the above embodiment, the garbage is decomposed by microorganisms. However, the constitution of the present invention is to dry garbage without using microorganisms. The present invention can be applied to a processing apparatus that only performs processing.

Further, in the garbage processing apparatus 1 described in the above embodiment, when the level of the garbage processing material 12 is detected to be over, the user is warned by lighting the LED. It is also possible to lock the gate 10 for opening and closing the garbage inlet 9 in a closed state, and control the garbage to be in a state in which garbage cannot be input while the warning is issued.

Further, in the above-mentioned garbage processing apparatus 1, the mounting angle is set to a predetermined angle by using a flat stirring blade, but the stirring blade can take any shape.
The pushing surface for conveying the garbage may be set at a predetermined angle with respect to the rotation axis.
