Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for compressing garbage, and more particularly, to an apparatus for compressing garbage which automatically compresses garbage discharged from a kitchen or the like and pushes it into a garbage container. Is.

[0002]

2. Description of the Related Art Even if there is no resistance to directly touching pre-cooked foods such as vegetables, meats and fish, and foods prepared by cooking these foods, most of them become dirty once they become raw garbage. You will feel resistance to touching it. Therefore, as a device for handling raw garbage without touching it,
Although an apparatus for treating garbage such as a disposer has been developed from the past, it is well known that it has not been popularized because a satisfactory result has not been obtained in terms of usability and environmental measures.

By the way, garbage is generally bulky, and its volume can be reduced to a fraction when compressed.
The inventor has found that the adhered water flows to the drain side in the process of draining / compressing, but the BOD is not so different from the case where the raw dust is not compressed unless the raw dust is cut into fine pieces. We have confirmed by experiments that bleeding does not come out, and we are developing a food waste compression processing device that can be incorporated into a sink in a home.

[0004]

By the way, the function required for a food waste compacting device for treating food waste produced at home is that a relatively small and hard material such as fish roe or chicken bones, which is usually produced in home cooking, is used. BOD in wastewater does not get clogged in the narrow part of the equipment with solid materials and elastic fibrous vegetables such as Chinese cabbage, and by compressing raw garbage.
A device that does not increase in value is required.

The present invention has been made in view of the above problems, and suppresses an increase in BOD in wastewater as much as possible to drain raw garbage, and the drained raw garbage is compressed and collected. It is an object of the present invention to provide a raw garbage compression processing device that does.

[0006]

In order to achieve the above-mentioned object, the structure of an apparatus for compressing garbage according to the present invention is such that a cylinder is arranged in a vertical direction and a partition with an opening for dropping garbage is formed in the middle. , A raw garbage inlet is opened at the upper end of the cylinder, a drainer chamber is formed between the raw garbage inlet and the partition, and a compression / delivery chamber for compressing and delivering the raw garbage is formed below the partition. , Open the garbage outlet passage on the peripheral wall of this compression / delivery chamber, and attach the rotary drive shaft so that the upper end reaches the draining chamber through the compression / delivery chamber. A blade is formed on the rotary shaft that forms a hole and moves the garbage inside the drainer chamber to the drop port, and it is compressed / sent and a rotor is mounted on the rotary shaft inside the chamber. In addition to having a cylindrical surface that rotates close to the peripheral wall of the delivery chamber, Parts is formed in a shape spaced by chamber wall and spacing the compression and transmission, is characterized in that fitted with vanes moved back and forth in contact with the rotor rotation direction poorly rotor openings of the garbage outlet passage.

[0007] It is preferable that a shutter and a lattice protector are attached to the garbage input port so that a hand is carelessly put in the water draining chamber to prevent an injury with a blade. Further, it is preferable to attach a switch for turning off the electric motor when the shutter and the protector are removed. Garbage that does not fit into the compression / delivery chamber can be broken by attaching scissors between the drop port and the rotor, but cutting it at the top edge of the rotor in the rotational direction and / or the drop port side. Attaching a cutting blade is effective for cutting bones and the like.

The garbage exit passage is provided with a throttle,
By providing the bend, resistance is generated to the garbage moving in the passage, and a back pressure is generated when the rotor compresses the garbage. The back pressure generation may be appropriately determined in accordance with the actual situation, but if the back pressure is small, the amount of water in the compressed garbage increases, and if the back pressure is too large, the power and mechanical strength of each part of the device increase. Not preferable.

[0009]

[Operation] A drainer chamber and a compression / delivery chamber are arranged in the vertical direction through a partition, and a blade is attached to the peripheral surface of the drainer chamber to prevent clogging of the drainage hole, and to compress raw garbage compressed by a rotor and a vane.・ The above-mentioned configuration for pushing out to the raw garbage outlet passage opening on the peripheral wall of the delivery chamber attaches while cutting or breaking the raw garbage by the raw dust drop opening and the rotor opened in the partition wall with the smallest possible floor area. Since the water can be drained and the garbage can be compressed, the treatment time can be shortened and the BOD in the wastewater can be maintained within the range of general domestic wastewater.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the accompanying drawings with reference to the accompanying drawings. As shown in FIGS. 1 to 5, the raw garbage compression processing apparatus 1 of this embodiment includes a drainer chamber 2, a compression / delivery chamber 3, a vane 4 and an outlet passage 5 (particularly FIG. 4). It is attached in a hanging manner to a cylindrical member 7 attached to an opening 6a for washing water provided in the bottom of a sink 6 of a domestic sink. That is, in the cylindrical member 7, the outer flange 7b of the cylindrical member 7 is placed on the ring-shaped step portion 6b provided at the inner peripheral edge of the opening 6a via the rubber packing 7a, and the spacer 7c is inserted from below the sink 6 via the spacer 7c. Ring member 7d
Is screwed and fixed to the cylindrical member 7.

A bottomless cylindrical drainer 8 provided in the drainer chamber 2 is attached to the inner flange 7e of the cylindrical member 7 in a suspended manner, and a restraining member 8b is press-fitted and fixed onto the outer flange 8a of the drainer 8. Then, the garbage input port E was formed. The drainer 8 has a plurality of drainage holes 2a. Next, the casing 1a of the raw dust compression processing apparatus 1 was inserted into the drainer 8, and the holding member 1b was screwed and fixed to the cylindrical member 7. That is, the water draining chamber 2 includes the water draining chamber 8 and a partition wall 9 between the water draining chamber 2 and the compression / delivery chamber 3.
It is formed by and. The drainer 8 was accurately positioned with respect to the partition wall 9 by a cylindrical positioning member 8c formed integrally with the partition wall 9. Further, the positioning member 8c is provided with slit-shaped openings 2b at a plurality of positions,
The drainer 8 is configured so that water can be discharged from the drainage hole 2a of the portion fitted into the positioning member 8c. In addition, the casing 1a and the cylindrical member 7 are integrated, and a short positioning member 8c is provided.
The slit-shaped opening 2b can be eliminated by positioning by means of.

The adhering water W released from the raw garbage contained in the water draining chamber 2 is discharged from the water draining hole 2a into the casing 1 described above.
It is formed so as to flow into a drainage channel D formed between a and the positioning member 8c and flow out from the drainage pipe 10a to a sewer pipe (not shown). The partition 9 is provided with a drop opening for compressing and sending out raw garbage (not shown) in the draining chamber 2 and dropping it into the chamber 3. The shape of the drop port 11 is preferably large so that the garbage in the drainage chamber 2 can easily fall. In this embodiment, as shown by a solid line in FIG. 3 and a two-dot chain line in FIG. It formed like a heart. Then, in order to convey the garbage on the partition wall 9 to the drop port 11, the blade 12 arranged in the water draining chamber 2 is attached to the rotary drive shaft 13 and is arranged so as to rotate close to the inner surface of the water drainer 8.
It was made possible to remove the solid matter from the drain hole 2a. In addition, reference numeral 12a shown in each drawing indicates the blade 12 on the rotary drive shaft 13.
Is a member for fixing.

A protector 14 is fitted inside the restraining member 8b of the water draining chamber 2. Protector 14
Is composed of a ring portion 14a, a linear lattice 14b and a ring lattice 14c, and the size of the lattice is such that an ordinary garbage can pass though an infant cannot get it. The through hole 14d shown in FIG. 1 is a hole into which a protector detection member (not shown) for a limit switch that turns off the current flowing through the electric motor that drives the rotary drive shaft 13 is inserted. The protector detecting member is formed by a bar urged in a pushing direction by a return spring, for example.
When the switch is attached, the limit switch is pushed back to turn on the limit switch, and when the protector 14 is removed, the limit switch is turned off so that the electric current does not flow to the electric motor even when the main switch is turned on.

As shown in FIGS. 1 and 4, the vane 4 is arranged on the lower side in the rotational direction of the portion where the compression / delivery chamber 3 opens to the outlet passage 5, and is whitened by a return spring (not shown). It was attached so as to be always in contact with the rotor 15 by a rod 4a biased in the direction of the arrow. Rotor 15
Is formed into a shape in which the shape of the drop opening 11 is enlarged in a similar manner,
The cylindrical surface 15a is substantially in contact with the compression / delivery chamber peripheral wall 3a,
Garbage is stored in the space between the constricted side and the peripheral wall 3a of the compression / delivery chamber. The rotor 15 then rotates and compresses
The raw dust sandwiched between 15b and the vane 4 is extruded toward the outlet passage 5 side.

The rotor 15 is rotated by a rotational position detecting device (not shown) such as a limit switch so that the raw garbage non-adhering water W drops slightly between the rear side of the rotor 15 in the rotational direction and the raw dust drop opening 11. I made a gap and stopped. As a result, water is prevented from entering the compressed raw garbage and the draining of the raw garbage put into the water draining chamber 2 is promoted. Further, since the outlet passage 5 is provided with a curved portion between itself and the throttle portion 16, a back pressure is generated by this portion due to the resistance to movement of compressed food waste, so the throttle ratio of the throttle portion 16 is set to a very small value. .

In the present embodiment, the rotor 15 has a heart-like shape in order to accommodate as much garbage as possible into the compression / delivery chamber 3, but this is, for example, an ellipse. It has been confirmed that there is no hindrance to the compression / delivery if the vane 4 has a shape such that the vanes 4 can be brought into contact with each other smoothly. The adhering water squeezed out due to the volume reduction due to the compression of raw garbage is a drainage hole 3 formed in the bottom wall 3b of the compression / delivery chamber 3.
It was made to flow from c to the drainage chamber d. In this embodiment, the bottom wall 3b
The drainage hole 3c was opened on the entire surface so that the raw water adhering to the garbage that leaked out between the drop port 11 and the rotor 15 was not compressed and sent out and stayed in the chamber 3. The position where the drain hole 3c is opened is not particularly limited, and may be appropriately provided in accordance with the actual situation.

The water flowing into the drainage chamber d is discharged from the drainage pipe 10b to the sewer pipe. Reference numeral 17 shown in FIG. 4 is a blade for pushing out the raw dust protruding from the compression / delivery chamber 3 with the inner peripheral edge 11a of the drop port 11 on the outlet passage 5 side. However, depending on the output of the electric motor used, even if the blade 17 is not attached, unless the blade is particularly hard garbage, the rotor 15
And the inner peripheral edge 11a can be broken. As described above, the garbage can be extruded from the squeezing portion 16 by being drained, broken, and compressed to reduce its volume. In each drawing, reference numeral 17a is a bracket for mounting an electric motor (not shown), 17b is a bearing chamber, 17c is a seal portion, and 17d is a power transmission gear.

6 to 8, a means for packing the garbage pushed out from the squeezing portion 16 will be described. Aperture
A bent pipe 19 having a bag locking plate 18 for mounting a garbage bag is attached to the 16 garbage outlet side, and a shutter 20 for opening and closing the garbage outlet 18a opened in the bag locking plate 18 is attached. This shutter 20 is rotated between a closed position shown by a broken line and an open position shown by a chain double-dashed line by a lever 20b attached via a connecting shaft 20a, and the raw garbage outlet 18a is opened and closed when the dust bag is attached and detached. It is closed to prevent garbage from falling off. Although the bent pipe 19 shown in FIG. 7 is bent at 90 °, the bending resistance can be reduced to reduce the extrusion resistance. As a result, the bag locking plate 18 may be inclined to some extent.

The bag locking member 21 is made of a rubber elastic body, and is a member for holding the dust bag 22 (only the outline is shown) covering the bag locking plate 18 from the outside. The bag locking member 21 has a ring shape and is elastically engaged with the outer peripheral edge of the bag locking plate 18 to seal the mouth of the dust bag 22, and the inner peripheral edge 21a is concave or grooved at least in the central portion. It is formed into a shape and is formed in a shape that does not easily come off from the bag locking member 21. In this way, the garbage bag has a certain size, and if the water does not seep out, a plastic bag delivered in a supermarket or the like can be used. The extension 20c of the lever 20b
Is a member that prevents the bag locking member 21 from being attached or detached unless the shutter 10 is closed. The garbage bag 22 is carelessly removed to prevent the garbage from falling off.

The bag locking means described above and the rotor 15 provide a drop port.
By using a means for closing 11, the generation of a foul odor can be achieved without using anti-corruption means such as ozone.
It can be suppressed to the same level as a conventional sink. FIG.
Reference numeral 23 indicates a platform scale that stops the electric motor when the amount of raw garbage in the garbage bag (not shown) reaches a certain weight. That is, when the garbage is filled inside the bag locking plate 18, the garbage is accumulated on the platform scale 23 through the bag. Since the platform balance 23 is provided with the measuring springs 23a at the four corners and the limit switches 23b at the center thereof, when a certain amount of garbage is filled, a switch circuit (not shown) can be activated to stop the electric motor. . Further, reference numeral 24 is a holding plate that supports a garbage bag filled with raw garbage, so that when a garbage bag filled with a predetermined amount of raw garbage is pulled in the direction of the white arrow, it is elastically deformed in the direction of the arrow and can be taken out. did. Thus, the pressing plate 24 is elastically deformed by a relatively weak force, but since the upper end of the dust bag is fixed to the bag locking plate 18 by the bag locking member 21,
There is no danger of lying sideways. Reference numeral 25 shown in FIG. 8 is a platform scale.
It is a bracket that holds 23 and the pressing plate 24.

In order to dispose of raw garbage with the raw garbage compression processing apparatus 1 described above, the apparatus is stopped during cooking, etc.
The generated garbage will be thrown into the draining chamber one after another. During that time, washing water may be used freely as in the conventional case. After cooking is completed, large garbage that does not pass through the protector, such as large garbage, is thrown in, and water is drained for a certain period of time, for example, during meals. When the electric motor is activated after draining, the blade 12
And, the rotor 15 starts to rotate, and the raw garbage is compressed and delivered from the drop port 11 and drops into the chamber, the raw garbage that does not fit in is cut off, and the compressed raw garbage is pushed out into the garbage bag 22. If water is to flow into the sink 6 during operation of the device, the electric motor is stopped. When a predetermined amount of garbage is stored in the garbage bag 22, the platform scale 23
Is activated and the electric motor is stopped, so it is possible to replace it with a new dust bag 22 and activate the main switch again. It was confirmed that the raw garbage compression processing apparatus 1 of the present embodiment uses an electric motor having an output of 90 W and can process raw garbage from a general household with a family of four at a speed of about 3 minutes per batch.

A switch for turning on / off the shutter 20 or the lever 20b may be provided to give an alarm when the shutter 20 is closed, a lamp is turned on, or the electric motor is turned off. Also, in system kitchens, etc., shut off the water in the sink during the garbage compression process,
You can prevent water from coming out of the tap. Further, although the bag locking member 21 is formed in a special cross-sectional shape, for example, as shown in FIG. 9, an O-ring is used for the bag locking member 21,
The shape of the peripheral edge of the bag locking plate 18 in contact with the dust bag 22 is made to project outside from the center so that the bag locking member 21 can be stably supported and the dust bag 22 can be strongly locked. Such,
Various modifications can be implemented.

Further, as described above, since the water discharged from the compression / delivery chamber 3 to the drainage chamber d contains the water squeezed out from the compressed raw garbage, the solid content is higher than that of the water discharged from the drain hole 2a. The content increases. Therefore, solid matter may be accumulated in the drainage chamber d. The simplest way to prevent this accumulation is to incline the bottom wall of the drainage chamber d, but as shown in FIG. 9, it is discharged from the compression / delivery chamber 3 by the drainage flowing out from the drain hole 2a. This is a modified example in which the water used is diluted to prevent the accumulation of solids.

In FIG. 10, the raw garbage adhering water discharged from the drain hole 2a flows into the drain chamber d from the drain pipe 10a. In this modification, the water is introduced from the tangential direction into the drainage chamber d so that the bottom wall 3b is not splashed with water. The water from the drain pipe 10a cleans the inside of the drain chamber d and flows out from the drain pipe 10b. The drain pipe 10c shown in FIG. 10 is an overflow pipe when water stays in the drain chamber d for some reason. It was confirmed that the drainage chamber d and the bearing chamber 17b are effective in preventing the accumulation of the solid content by devising the layout. With respect to other reference numerals, the same members as those shown in FIGS.

[0025]

As described above, in the apparatus for compressing garbage according to the present invention, the drainer chamber and the compression / delivery chamber are arranged in the vertical direction through the partition wall, and the blade is attached to the inner surface of the drainer chamber to drain the water. The holes are prevented from clogging, and the raw garbage compressed by the rotor and the vane is compressed and sent out to the raw garbage outlet passage opening in the peripheral wall of the chamber, so the floor area can be made as small as possible. , It is possible to automatically pack the garbage that has drained non-adhesive water in a stationary state into a size that can be compressed / extruded while compressing or draining it while cutting or breaking it, and to automatically pack it as reduced volume garbage, so there is no feeling of filth.
The garbage treatment can be performed in a short time, and the BOD value in the wastewater can be maintained at the value of normal domestic wastewater.
