Abstract

PURPOSE:To maintain dehydration for a predetermined time, conduct a highly efficient dehydration and prevent the clogging of the device and the remaining of garbage, by flushing garbage down through a cylindrical shaft and a cylindrical screw portion provided coaxially with a hopper and a dehydration basket. CONSTITUTION:The garbage flushing down into a hopper 33 together with water is pulverized by a hammer 41 being rotated at a high speed by a motor 36 and a fixed edge 43 and dropped onto the bottom of a dehydration basket 44 through a cylindrical shaft 35 and a cylindrical screw portion 56. The garbage is pulled toward the inner peripheral surface of the basket from an opening 58 between a screw 55 and the bottom of the dehydrating basket 44 due to the centrifugal force of the dehydration basket 44 rotating at a high speed. During this time, the garbage is sent upwardly while remaining in the basket 44 for a predetermined time by the screw 55 rotating at a speed somewhat different from the dehydrating basket 44 under centrifugal dehydration and for discharging.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a kitchen waste processing machine that dehydrates and recovers kitchen waste.

(Conventional technology) FIG. 6 shows a conventional centrifugal separation type kitchen waste processing machine.

This kitchen waste processing machine includes a dewatering basket 11 in the shape of an inverted truncated cone that rotates at high speed within a casing 10, and a crushing section 14 consisting of a fixed blade 12, a rotary hammer 13, and the like.

The kitchen waste dropped into the hopper 16 together with water from the kitchen table 15 is crushed in the crushing section I4 and then blown to the inner bottom periphery of the dewatering basket 11 by centrifugal force, and the dewatering basket 11 rotates at a higher speed. The water rises along the tapered inner circumferential wall of the dewatering basket 11 under the influence of centrifugal force, is dehydrated while reaching the discharge chamber 17, is blown away by the blades 18, and is discharged into the storage bag 19. The separated water passes through the dehydration chamber 20 and is discharged from the drain pipe 21.

(Problems to be Solved by the Invention) However, the conventional kitchen waste processing machine described above has the following problems.

(2) When a large amount of water is flushed from the sink 15, the water is discharged along with the kitchen waste by rising up the inclined wall surface of the dewatering basket 11, resulting in poor dewatering efficiency.

■Depending on the type of kitchen waste, the rate at which the kitchen waste rises on the inner wall surface of the dehydrated Basquera T-11 differs, resulting in a difference in the dewatering rate. For example, something relatively hard and dense like a radish will rise slowly and will be sufficiently dehydrated, but a soft something like a tomato will rise immediately with water in it, so it will not be dehydrated enough. It cannot be done.

(2) There is also a risk that kitchen waste may adhere to and remain on the inner surface of the dewatering basket 11. In particular, the dewatering basket 11 is easily clogged, which is one of the causes of a decrease in the dewatering rate. In addition, there is a problem that residual kitchen waste rots during the summer and causes a bad odor.

The present invention has been made to solve the above-mentioned problems, and its purpose is to provide a kitchen waste disposal machine that solves the problems of clogging of the dewatering basket and residual kitchen waste, and that can also be downsized. It is in.

(Means for solving the problem) The kitchen waste processing machine of the present invention according to the above object includes a casing,
a dewatering basket disposed within the casing and capable of rotating at high speed around an axis in a horizontal plane; a hopper disposed above the dehydrating basket coaxially with the dehydrating basket and allowing thrown kitchen waste to flow down onto the dehydrating basket; In a kitchen waste processing machine that includes a crushing means for crushing kitchen waste flowing down in a hopper, and dehydrates and discharges the kitchen waste flowing down by centrifugation, a cylindrical shaft body extends from the lower end of the hopper into the dewatering basket coaxially with the dewatering basket; The cylindrical body part has a cylindrical body part that is opened vertically in the center and has an opening formed at the lower end for discharging kitchen waste toward the inner circumferential surface of the dehydration basket, and rotates on the cylindrical shaft body in the cylindrical body part. It is freely fitted to the outside and has screw blades on the outer periphery of the cylindrical body part,
It is characterized by comprising a screw that rotates at high speed in the same direction as the dewatering basket and conveys kitchen waste by a speed difference with the dewatering basket, and a drive means that rotates the dewatering basket and the screw at high speed with a predetermined speed difference. do.

It is effective to provide a concave groove on the outer end surface of the screw blade, and to provide a contact piece in this concave groove that makes elastic contact with the inner peripheral surface of the dewatering basket.

Furthermore, since kitchen waste tends to adhere to the inner periphery of the lower part of the cylindrical body of the screw, it is more convenient to provide a scraping block at the lower end of the cylindrical shaft that slides into the corner of the cylindrical shaft.

It is advantageous if a common drive motor is used as the drive means for the dewatering basket and the screw. In this case, the dewatering basket is directly connected to the output shaft of the drive motor, and the screw is connected to the output shaft via a drive transmission system such as a gear. This output shaft can also serve as a driving source for a rotary hammer of the garbage crushing means.

The rotation direction of the dehydration basket and screw shall be the same. When rotating the screw in a direction that reduces the lead angle, rotate the screw at a slightly faster speed than the dehydration basket, and when rotating the screw in a direction that increases the lead angle, rotate the dehydration basket slightly faster than the screw. Set to rotate at speed.

(Function) The kitchen waste that has flowed down into the hopper with water is crushed by the crushing means, passes through the cylindrical shaft and the screw barrel, and falls onto the inner bottom of the dewatering basket. , is blown toward the inner circumferential surface of the dehydrating basket from the opening between the lower surface of the screw cylinder and the inner bottom surface of the dehydrating basket.

Here, the kitchen waste is centrifugally dehydrated and discharged while being conveyed upward by a screw that rotates at a slight speed difference with the dewatering basket.

The time that kitchen waste remains in the dewatering basket and undergoes centrifugal dehydration is determined by the difference in rotational speed between the dewatering basket and the screw, and does not depend on the type of kitchen waste that contains various miscellaneous items. Can handle kitchen waste.

Since the screw is fitted onto the cylindrical shaft that extends from the lower end of the hopper, there is nothing that prevents the kitchen waste from falling through the cylindrical shaft and the inside of the screw, allowing the kitchen waste to fall smoothly and preventing it from sticking. can be reduced by that much.

The contact piece provided in the concave groove on the outer end surface of the screw blade comes into elastic contact with the inner peripheral surface of the dehydration basket, cleaning the inner peripheral surface, and eliminating the gap between the inner peripheral surface of the basket and the fibers on the outer end of the screw blade. This prevents kitchen waste such as grains from entering and getting tangled.

A scraping block fixed to the lower end of the cylindrical shaft slides against the corner formed at the bottom of the screw to prevent kitchen waste from adhering to it.

In addition, by rotating the screw in the direction in which the lead angle of the screw blade increases, and by rotating the dewatering basket in the same direction and at a slightly higher speed than the screw, the kitchen waste can be transported, thereby preventing the kitchen waste from getting tangled in the lower part of the screw. is prevented.

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described in detail based on the accompanying drawings.

(First Embodiment) In FIG. 1, 30 is a cylindrical casing, which is sealed by a bottom plate 31 and a top plate 32.

A hopper 33 is provided on the upper surface of the casing 30 coaxially with the casing, and communicates with the inside of the casing through a cylindrical shaft body 35 that loosely penetrates a through hole 34 provided in the top plate 32 and opens into the casing 30. Note that the cylindrical shaft body 35 is also provided vertically so as to be coaxial with the casing 30 and the hopper 33.

Reference numeral 36 denotes a drive motor located below the casing 30 and fixed to an appropriate member (not shown), whose output shaft 37 rotatably passes through a boss 38 of the casing bottom plate 31 and extends inside the casing 30 and the cylindrical shaft body 35. It faces into the lower part of the hopper 33.

Note that 39 is a bearing, and 40 is a cap fixed to the output shaft 37, which covers the boss 38 to prevent moisture from entering into the boss.

At the upper end of the output shaft 37, there is a disc 4 equipped with a hammer 41 on the upper surface.
2 is fixed and the disc 42 rotates together with the output shaft 37, whereby the kitchen waste dropped into the hopper 33 is crushed by the hammer 41 and the fixed blade 43 provided on the inner wall of the hopper 33.
The crushed kitchen waste falls from the gap between the hammer 41 and the fixed blade 43 through the cylindrical shaft 35 into a dewatering basket to be described later.

44 is a dewatering basket disposed inside the casing 30, which has a shallow dish shape and is connected to the output shaft 3 passing through the center of the bottom surface.
7, and rotates at high speed in a horizontal plane around an output shaft 37.

The dewatering basket 44 has a tapered circumferential wall so that the diameter decreases upward, and an inward protrusion 45 is provided on the inner wall of the casing, and a flange 47 is provided on the upper end of the circumferential wall facing outward. By slidingly contacting the lower surface, a salt water chamber 46 is formed between the outer wall surface of the dewatering basket 44 and the inner wall surface of the casing 30. Flange part 47
A protrusion 48 is formed on the upper surface, and the outer wall of the protrusion 48 faces the inner surface of the inward protrusion 45 .

A large number of salt water holes 50 are opened in the peripheral wall and bottom surface of the dewatering basket 44, and salt water holes 50 are opened from the hopper 33 to the dewatering basket 44.
The water flowing down into the dehydration chamber 4 and the water centrifuged from the kitchen waste by the rotation of the dehydration basket 44 are transferred from the dehydration hole 50 to the dehydration chamber 4.
6 and drained from the drain port 51 provided in the casing 30.

Next, 55 is a screw, and screw blades 57 are provided on the outer periphery of a cylindrical body part 56 that opens in the vertical direction.
It is fitted onto the outside so that it can rotate freely around its axis. The outer periphery of the screw blade 57 is in sliding contact with the inner peripheral wall of the salt water basket 44, and the starting end of the lower part of the spiral of the screw blade 57 is in sliding contact with the inner bottom surface of the dewatering basket 44 and the corner of the inner peripheral wall, and the lower surface of the cylindrical part 56 is in sliding contact with the inner peripheral wall of the salt water basket 44. An opening 58 is formed between the lower surface of the cylindrical body portion 56 and the inner bottom surface of the dewatering basket 44 by inclining the opening 58 from the sliding contact portion at the lowest end substantially following the inclination (lead angle) of the spiral.

Therefore, the kitchen waste that has fallen from the cylindrical shaft 35 onto the inner bottom surface of the dewatering basket 44 is blown away from the opening 58 toward the inner circumferential wall of the salt water basket by the centrifugal force from the salt water basket 44.

The screw 55 is rotated at high speed by a drive motor 36 that rotates the dewatering basket 44 .

That is, the belt 63 is not hooked between the boot IJ-61 provided at the lower end of the rotating shaft 60 provided on the machine stand 59 outside the casing 30 and the pulley 62 provided on the output shaft 37 of the drive motor 36. A drive transmission system is constructed by passing a belt 66 over a pulley 64 provided at the upper end of the rotating shaft 60 and a pulley 65 provided at the upper end of the screw 55 at a portion protruding outside the casing 30. The driving force of the drive motor 36 is transmitted to the screw 55 through the drive transmission system, and the screw 55 connects to the dewatering basket 44.
is rotated at high speed in the same direction.

In this embodiment, the screw 55 is rotated slightly faster than the dewatering basket 44.

Therefore, the screw 55 is rotated slowly relative to the dewatering basket 44, so that the food waste in the salt water basket 44 is gradually transported upward along the inner peripheral wall of the dewatering basket 44 by centrifugal force.

Note that 52 is a bearing, and 67 is a fixing ring that prevents the screw 55 from being removed from the cylindrical shaft body 35.

At the upper part of the casing 30, there is a top plate 32 and an inward protrusion 45.
A discharge chamber 68 is formed which is separated from the salt water chamber 46 by a dehydration basket 44 and the like, and a discharge port 69 is opened at one end side of the discharge chamber 68.

A vane body 70 extends into the discharge chamber 68 from the upper end surface of the screw 55, and rotates at high speed within the discharge chamber 68 as the screw 55 rotates.

Note that the blade body 70 may extend from the upper end surface of the outer periphery of the dewatering basket 44.

71 is a storage bag that is detachably attached to the discharge port 69.

The kitchen waste processing machine configured in this way has a hopper 33.
At the upper end, attach the mounting tube 7 to the kitchen waste input lower 3 of the sink 72.
It can be attached via 4 etc.

Further, a drain pipe 75 is connected to the drain port 51.

Next, the operation will be explained.

The kitchen waste that has flowed down from the sink 72 into the hopper 33 with water is transferred to the hanger 4 which is rotated at high speed by the drive motor 36.
1 and the fixed blade 43, and flows down from the gap between the hammer 41 and the fixed blade 43, through the cylindrical shaft body 35, and onto the inner bottom surface of the dewatering basket 44. Most of the water from the sink 72 flows through the dehydration hole 50 provided at the bottom of the dehydration basket 44.
The water flows down into the dehydration chamber 46 and is drained from the drain pipe 75.

- When the dewatering basket 44 is rotated at high speed, the centrifugal force causes the screw and the dehydrating basket 4 to
4 and the inner bottom surface of the dewatering basket 44. Here, the kitchen waste is fed by a screw 5 which is rotated at a high speed slightly higher than that of the dewatering basket 44.
5, and is conveyed upward while being centrifugally dehydrated. The dehydrated kitchen waste is ejected from the upper surface of the screw 55 into the discharge chamber 68 by centrifugal force, but the impeller rotating at high speed together with the screw 55 It is ejected from the outlet 69 into the storage bag 71 by the outlet 7o.

As described above, since the outer end of the screw blade 57 of the screw 55 is in sliding contact with the inner circumferential wall of the hydrophilic basket 44, the inner sliding surface of the dewatering basket 44 is constantly rubbed, and clogging is prevented as much as possible. In addition, kitchen waste is dehydrated in the basket 44
The amount of time the kitchen waste remains in the container and undergoes centrifugal dewatering is determined by the rotation ratio of the dewatering basket 44 and the screw 55, regardless of the type of kitchen waste. Optimum hydrophilic effect can be mentioned.

In this embodiment, the depth of the dewatering basket 44 is made as shallow as possible, and the height of the entire apparatus can be set to a low height.In other words, in the conventional apparatus shown in FIG. A certain depth was required in order for the kitchen waste to rise naturally and ensure a predetermined dewatering time, but in this embodiment, the residence time of the kitchen waste in the dewatering basket 44 depends on the depth of the dewatering basket 44. This is related to the fact that the rotation ratio of the dewatering basket 44 and the screw 55 can be freely set, so a shallow dewatering basket 44 can be used.

The shape of the dewatering basket 44 is not limited to that shown in each of the above embodiments, but may also have a diameter increasing toward the top.

Also, since it is possible that fine foreign matter such as kitchen waste may adhere to the outer peripheral wall of the dehydration basket 44, although it is not shown in the figure, the dehydration chamber 4
It is also possible to provide a scraper in sliding contact with the outer circumferential wall of the dewatering basket 44.

The drive system for the dewatering basket 44, the screw 55, and the crushing section is not limited to the above embodiment, and the driving sources for the dewatering basket 4.4 and the screw 55 may be provided separately.

Further, the kitchen waste disposal machine is not necessarily installed directly below the kitchen waste inlet of the sink, but can be installed at an appropriate position below the sink using, for example, a flexible connecting pipe.

(Second example) FIG. 2 shows yet another embodiment.

In this embodiment, a groove 80 is formed on the outer end surface of the screw blade 57, and a spiral contact piece 81 made of an elastic member is fitted into the groove 80.

This contact piece 81 comes into elastic contact with the inner peripheral surface of the dewatering basket 44 due to its elasticity that tends to expand outward.

Therefore, according to this embodiment, when the screw 55 rotates relatively slowly with respect to the dewatering basket 44, the contact piece 81 comes into elastic contact with the inner circumferential surface of the dehydrating basket 44 and rubs the inner circumferential surface. A cleaning effect is produced, effectively preventing clogging of the dewatering basket 44. Furthermore, the inner circumferential surface of the dewatering basket 44 is cleaned and kitchen waste does not adhere to it and accumulate therein, so it is possible to prevent the generation of bad odors due to rotting kitchen waste in summer or the like. Furthermore, if hard kitchen waste such as seashells is caught between the inner circumferential surface of the dewatering basket 44 and the contact piece 81, the contact piece 81 will be removed from the groove 80.
Since it escapes inward, damage to the contact piece 81 and screw blade 57 can be prevented.

FIGS. 3(a) to 3(d) show various application examples of the contact piece 81.

In the case of FIG. 5A, a spring 82 is interposed in the groove 80 of the screw blade 57, and the spring 82 further presses the contact piece 81 outward. In the case of the same figure (b), the example which uses the wire for the contact piece 81 is shown. In the case of the same figure (C), the contact piece 81 is made of an elastic body such as sponge rubber. In the case of FIG. 8D, a brush 81 as a contact piece is installed in the groove 80 so that its tip protrudes further outward than the screw blade 57.

In this embodiment, the tip of the brush 81 also enters the dehydration hole 50 of the dehydration basket 44, so that it is possible to further prevent kitchen waste from adhering to the inner wall of the dehydration hole 50, and the cleaning effect is further improved.

(Third example) FIG. 4 shows yet another embodiment.

This embodiment is a further improvement on the apparatus shown in FIG.

In the device shown in FIG.
5 is supported to rotate via a bearing 52. Further, the screw blades 57 are provided on the outer periphery of the cylindrical body portion 56, and the lower surface of the cylindrical body portion 56 is formed into an inclined surface approximately corresponding to the angle of the screw blades 57.
An opening 58 for discharging kitchen waste was formed between the inner bottom surface and the inner bottom surface.

By the way, if the lower end of the cylindrical body part 56 is cut along a plane corresponding to the lead angle and the wall thickness of the cylindrical body part is left as is, the inner wall of the cylindrical body part 56 and the lower surface of the cylindrical shaft body 35 and the bearing 52 will be A right-angled corner is formed in between, and kitchen waste tends to adhere to this corner. Therefore, as shown in FIG. 1, the inner wall at the lower end of the cylindrical body part 56 is shaved to form an inclined wall 53 within a range where the mounting strength of the screw blade 57 is maintained. However, even if the inclined wall is formed in this way, there is a risk that kitchen waste will gradually adhere to and accumulate on the inclined wall 53, rot, and emit a bad odor. The closer the angle of the inclined wall 53 is to the horizontal, the less kitchen waste will adhere to it, but this requires increasing the wall thickness of the cylindrical body 56, which goes against the demand for miniaturization.

Therefore, in this embodiment, as is clear from FIG. 4, regardless of the wall thickness of the cylindrical body 56, the angle of the inclined wall 54 from the lower end of the cylindrical body 56 (the angle from the horizontal position) is The angle was set to be smaller than 45, which is relatively difficult to adhere to. Then, naturally, a corner portion A is formed between the lower end of the cylindrical shaft body 35 and the inner wall of the cylindrical body portion 56. In this embodiment, the scraping block 83 that comes into sliding contact with this corner part is attached to the cylindrical shaft body 3.
5. Fixed to the lower end. The scraping block 83 may be shaped like a blade, but if it is shaped like a blade, there is a risk that the scraped kitchen waste may adhere to and remain on the blade. Therefore, as is clear from the bottom view of FIG. 5, it is preferable that the scraping block 83 is formed into a long block shape in the direction of rotation of the cylindrical body portion 56. Further, as is clear from FIG. 4, it is preferable that the surfaces of the scraping block 83 other than those that come into sliding contact with the corner portions A are sloped surfaces that are gently inclined with respect to the horizontal position.

As described above, in this embodiment, since the inclined wall 54 is set at a gentle angle, kitchen waste is relatively attached to the inclined wall 54, and even if it is attached, it tends to fall. In addition, the kitchen waste adhering to the corner portion A is scraped off by the scraping block 83, and there is less kitchen waste adhering to the scraping block 83.

(Fourth Example) Next, another example, not shown, will be described.

In each of the above embodiments, the screw 55 is connected to the dehydration basket 4.
An example is shown in which the screw 55 is rotated at a high speed slightly faster than 4, and the kitchen waste is conveyed so as to be scooped up by the screw 55 itself due to the difference in rotation. However, in order to make the opening 58 for releasing kitchen waste between the lower surface of the cylindrical portion 56 of the screw 55 and the inner bottom surface of the dewatering basket 44 as large as possible, the lower portion of the cylindrical portion 56 is located on the side where the screw blades 57 extend. It is preferable to make a large notch in the half circumference on the opposite side. However, if this is done, the cut end surface of the inclined wall 53.54 will be exposed at a position corresponding to the lowest end portion of the inclined wall 53.54, and this cut end surface will be exposed in the rotation direction of the screw 55. Fibrous kitchen waste becomes easily tangled.

Further, in the scooping portion of the screw, fibrous kitchen waste enters the gap between the screw and the inner bottom surface of the basket, resulting in a similar tangled phenomenon of kitchen waste.

Therefore, in this embodiment, the screw 55 is rotated at high speed in the direction in which the lead angle increases, that is, in the direction in which the screw 55 itself cannot transport the kitchen waste upward.

- Force the water basket 44 to be pumped at high speed in the same direction as the screw 55 and at a slightly faster speed than the screw 55. Due to this speed difference, the kitchen waste is sent onto the screw blade 57 by the dehydration basket 4
4 is conveyed on the screw blade 57 by the frictional force between the inner circumferential surface thereof, and is fed into the discharge chamber 68 and discharged.

In this embodiment, the cut end surface of the screw 55 is located at the rear end in the rotational direction of the screw 55, so kitchen waste is prevented from getting entangled with the cut end surface, and the inclined walls 53, 54
Reduces the adhesion of kitchen waste to

The present invention has been variously explained above with reference to preferred embodiments, but the present invention is not limited to these embodiments and can of course be modified in many ways without departing from the spirit of the invention. That's true.

(Effects of the Invention) Since the present invention is configured as described above, it produces the following effects.

In the kitchen waste processing machine according to claim 1, the kitchen waste is conveyed in the dewatering basket by the screw, so that even if the kitchen waste contains various miscellaneous items, it will not stay in the dewatering basket regardless of the type of kitchen waste. By setting the dehydration time based on kitchen waste that is not easily dehydrated, kitchen waste can be processed with a constant high dehydration rate. In addition, the kitchen waste is made to flow down through the cylindrical shaft body and the cylindrical body of the screw, which are provided coaxially with the hopper and the dewatering basket, and the kitchen waste is blown onto the inner circumferential wall of the dewatering basket from the opening at the lower end of the cylinder.
There is nothing in the kitchen waste falling space that prevents the kitchen waste from falling, allowing the kitchen waste to fall smoothly and preventing the kitchen waste from sticking to the kitchen waste.Also, even though a screw is provided, the kitchen waste supply path can be short-circuited, and the equipment Can be made smaller. Furthermore, the residence time of kitchen waste in the dehydration basket can be set by adjusting the rotation ratio of the dehydration basket and the screw, so the dehydration basket can be set to be shallow, which also makes it possible to downsize the entire device and reduce the space below the sink. We have provided a kitchen waste disposal machine that can be conveniently installed in any space.

In the kitchen waste disposal machine of the second aspect, since the contact piece comes into elastic contact with the inner circumferential surface of the dewatering basket, the cleaning effect on the inner circumferential surface is further increased, and furthermore, when a hard foreign object is present, the contact piece is removed from the groove. This prevents damage to the contact pieces and screw blades.

In the kitchen waste processing machine according to the third aspect, it is possible to prevent kitchen waste from adhering to the corner portion of the lower part of the screw, and it is possible to prevent the occurrence of a bad odor due to rotting kitchen waste in summer or the like.

In the kitchen waste processing machine according to the fourth aspect, the dewatering basket and the screw can be driven by a single drive motor, thereby simplifying the apparatus.

In the kitchen waste processing machine according to the fifth aspect of the present invention, the drive motor can also be used as a drive unit for the kitchen waste crushing means.

In the kitchen waste processing machine according to the sixth aspect of the present invention, since the screw is rotated in the direction in which the lead angle increases, it is possible to effectively prevent kitchen waste from getting entangled with the lower part of the screw.
