DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage processing apparatus for processing garbage such as garbage.

[0002]

2. Description of the Related Art Conventionally, garbage such as kitchen garbage is collected and stored in garbage bags for each household, transported to a garbage collection point as combustible garbage on a predetermined collection day, and discarded. The accumulated garbage is
Collected by local governments and disposed of by incineration or landfill. However, perishable garbage such as vegetable scraps, meat, fish, garbage, and the like from the kitchen rot during the storage or collection process, giving off odors, and have problems in hygiene and the environment.
In addition, with the advent of an aging society, regular high-rise housing, such as apartment houses, has become a heavy burden to periodically carry out garbage.

[0003] In order to dispose (dispose) the garbage at hand, a disposer is installed under a sink drain of a kitchen in each home, and the garbage introduced into the drain is crushed by a high-speed rotating hammer. A method of flowing water into a water pipe together with water is used. In this case, when garbage with a high density such as an egg shell or a shell is included, or when the particle size at the time of crushing is large, the crushed garbage may settle in the horizontal drainage pipe and clog the drainage pipe. In addition, there is a problem that noise and vibration at the time of crushing are increased because garbage is crushed by a swing hammer rotating at high speed.

As one solution to these problems, a motor-driven cutter impeller installed in a casing having an inlet and an outlet feeds the inlet from the inlet directly connected to the sink drain. An indoor drainage system as disclosed in Japanese Patent Publication No. 7-18185 has been proposed as an indoor drainage system that cuts garbage that has been cut into a size that can pass through a drainage pipe, and pumps the waste from the outlet to the drainage pipe.

A crushing section is provided at one (upper portion) of a motor rotating shaft penetrating the motor body and connected to a drain port of a sink sink for crushing and liquefying garbage in the drainage. A crushing / pumping device using a pumping pipe and a crushing / pumping device provided with a pumping unit for pumping liquefied garbage mixed wastewater (in the lower portion) as shown in Japanese Utility Model Publication No. 6-45495 has been proposed. ing.

[Problems to be Solved by the Invention] The above Japanese Patent Publication No. 7-18185
In each of the devices described in Japanese Unexamined Patent Application Publication No. 6-45495 and Japanese Utility Model Publication No. 6-45495, there is an advantage that the waste can be disposed at hand and the drainage pipe can be prevented from being clogged by pumping.
Since the high-speed rotation operation for crushing and transporting the garbage is performed simultaneously, there is a problem that the noise at the time of crushing the garbage increases.

It is an object of the present invention to provide a garbage disposal apparatus or a garbage disposal system which can smoothly pump crushed garbage (garbage) downstream by a drain pipe and operate with low noise.

[0008]

In order to achieve the first object, a kitchen garbage disposal apparatus according to the present invention comprises a crushing means for crushing and liquefying garbage input from an input port, and a crushing means for the garbage. A storage unit that stores the garbage crushed by the storage unit, a pumping unit that pumps the garbage stored in the storage unit to a drain pipe, and a driving unit that drives the pumping unit and the crushing unit at different rotation speeds. Is provided.

[0009] More preferably, crushing means having a crushing screw for crushing and liquefying the garbage input from the input port, a storage section for storing the garbage crushed by the crushing means, and The apparatus includes a pumping unit having a pump for pumping the stored garbage to the drain pipe, and a driving unit having a driving motor for driving the pump and the crushing screw at different rotation speeds.

In the above configuration, the crushing operation by the crushing screw becomes quiet by operating the rotation speed of the crushing screw and the rotation speed of the pressure pump at appropriate speeds, respectively, and the pressure pump generates the required pressure force. can do. At this time, usually, the operating speed of the crushing screw is reduced to lower the noise during the garbage crushing operation, and the operating speed of the pump is increased to increase the pumping capacity. To do.
Thereby, the garbage can be smoothly transported in the drainage pipe, and the drainage pipe is hardly clogged. Further, by rotating the crushing screw at a low speed, it becomes easy to treat hard garbage such as chicken bones.

At this time, it is preferable that the driving means is driven by switching the crushing screw and the pressure pump with the same driving motor.

In this case, since the pressure pump and the crushing screw do not operate at the same time, operation with a small driving motor having a small capacity becomes possible.

Further, at this time, it is preferable that the rotation centers of the crushing screw and the pressure pump are arranged on the rotation axis of the drive motor.

Further, at this time, it is preferable that the driving means, the crushing means, and the pressure pump are arranged in this order from above along the rotation axis of the driving motor.

Further, at this time, it is preferable that the rotary shaft of the pressure pump is connected to the drive motor through a through-hole passing through the rotation center of the crushing screw.

Further, at this time, between the crushing screw and the pressure pump, there is a through hole at the center of rotation through which the rotary shaft of the pressure pump is passed, and the garbage sent is cut by a rotary blade. A cutting means may be provided.

Further, at this time, the crushing screw is rotated at 30 to 150 revolutions / minute, and
It is preferable to be rotated at 000 to 3000 revolutions / minute.

Further, in order to achieve the second object,
In each of the above kitchen waste treatment apparatuses, a water storage tank is provided,
The pumping means pumps the garbage to the drain along with the water in the water storage tank. Thereby, the garbage can be pumped with a sufficient amount of water, the garbage can be smoothly transported in the drain pipe, and the drain pipe is less likely to be clogged.

At this time, the water storage tank may store the fluid flowing from the inlet. As a result, the washing water discharged from the sink can be stored and used in the water storage tank, so that it is not necessary to use tap water particularly for pumping, and water can be saved.

Further, at this time, water is supplied from the storage section to the water storage tank, and water is absorbed from the water storage tank into the storage section by driving the pumping means. A filter may be provided between them. The filter provided in the storage section reverses the flow of water between the time when the drainage is stored in the water storage tank and the time when the pressure pump is operated, so that the filter is always automatically cleaned, and the clogging is unlikely to occur. can do.

Further, at this time, it is preferable that a hopper connecting the input port and the inside of the case containing the crushing screw is provided with a bypass flow path connecting the hopper and the water storage tank. As a result, even when the hopper is filled with garbage, normal drainage is not hindered.

Further, at this time, the water storage tank may be provided with a water level detecting means for detecting the water level in the tank, and the operation of the pressure pump may be automated based on the output of the water level detecting means.

Further, a kitchen garbage processing system is constituted by including a processing apparatus for processing garbage crushed by the above-mentioned kitchen garbage processing apparatus and fed to a drain pipe.

Further, since the kitchen waste disposal system is provided in a building such as an apartment house, it is possible to reduce the burden on residents for waste disposal and the like.

[0025]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a longitudinal sectional side view showing a first embodiment of a kitchen waste disposal apparatus main body according to the present invention.

In FIG. 1, reference numeral 21 denotes a garbage input port for inputting garbage including kitchen waste generated in a kitchen together with an appropriate amount of water, 22 a hopper for temporarily storing the input garbage, 23 Is crushing means for crushing the garbage in the hopper 22. The crushing garbage is crushed by squeezing and crushing while being conveyed downward by the slow rotation of the crushing screw-231, and the crushed garbage is cut. The rotary blade 241 that rubs against the plate 242 when pushed downward through a plate 242 having a plurality of openings constituting the plate 24.
Cut short. The cutting means 24 also cuts soft and tough garbage such as squid skin, chicken skin and corn skin which cannot be crushed by squeezing and crushing with a crushing screw-231 to a predetermined size. G 242
From the plurality of openings 243 provided in the crushed garbage storage unit 27 located below. Reference numeral 26 denotes a pumping means for forcibly transporting the crushed garbage together with water to a drain pipe. The crushed garbage sucked from the pumping inlet 262 by the high-speed rotation of the pumping pump 261 is drained from the pumping outlet 263. Forcibly drain into pipe.

Each of the above-mentioned units is a drive motor 251 to be described later.
On the axis of rotation of, crushing means, cutting means, storage section from above
The pumping means is provided in this order, and the rotating shaft of the drive motor 251 or the shaft of the crushing screw is provided so as to be inclined.

In the present embodiment, the crushing screw
Is installed at an angle to the floor and the crushing screw is above the rotary blade and plate, so the garbage thrown in from the crushing screw to the rotary blade and from above to below. Since the garbage is conveyed, the garbage can be conveyed to the rotary blade and the plate without stopping.
Accordingly, residue (crushed garbage waste) is less likely to be generated in the case 232, the crushing screw 231 and the plate 242. Furthermore, since water flows together, residues are less likely to be generated. Therefore, the odor due to the residue can be almost prevented.

Numeral 25 denotes a driving means for moving the crushing screw-231 and the rotary blade 241 arranged in series to 30-1.
Rotate slowly at 50 revolutions / minute, and
A reversible drive motor 251 for rotating the 61 at a high speed of 1000 to 3000 revolutions / minute and a transmission 252 are provided.
In the present embodiment, the drive motor 251 is provided on the upper side for ease of waterproofing or the like. However, the drive motor 251 is provided on the pump side for space or the like, or provided at another location to drive the belt. You may.

The hopper 22 is bent between the garbage inlet 21 and the opening (connection) into the case 232 in which the crushing screw 231 is stored.
Is set to 140 to 170 degrees. Thereby, the garbage thrown into the hopper is reliably taken into the crushing screw-231 without remaining in the middle of the hopper and crushed. If the bending angle of the hopper is too small, the garbage thrown in tends to stagnate at the bent part,
There is a risk of clogging inside. Therefore, it is desirable that the bending angle be about 140 degrees or more. As described above, the rotation axis of the crushing screw-231 is provided so as to be inclined at an angle of 20 to 70 degrees with respect to the floor or horizontal plane. The opening on the screw-231 side must be large, the effective crushing part of the crushing screw-231 becomes short, and the crushing function decreases.

In addition, the ordinary garbage arrives at the crushing screw without being clogged by the hopper by bending the hopper appropriately. As a result, it can be prevented from directly digging into the crushing screw. Also, even if the crushing screw scatters debris when crushing hard garbage, there is no inlet on the straight line of the crushing screw and it first hits the hopper, so it can hardly jump out from the garbage inlet directly. .

The internal volume of the hopper 22 is set to a volume that can sufficiently store daily garbage generated at home.

The crushing means 23 in this kitchen waste disposal apparatus
When the drive motor 251 rotates in the forward rotation direction, the crushing screw 231 driven by the drive motor 251 and the transmission 252 transfers the garbage thrown from the garbage inlet 21 to the right in the figure. 30 to 150 rotations /
Slow rotation in minutes. The garbage conveyed by the crushing screw-231 includes a crushing screw-231 and a case 232.
Crushed between and crushed by crushing. Then, when the garbage is sent out from the opening of the plate 242 to the crushed garbage storage part 27, the garbage is cut short by the rotating blade 241 which rotates while rubbing with the plate 242. In this cutting, soft and slender garbage such as uncrushed skin and streaks contained in garbage crushed by squeezing and crushing is cut short.

Next, when the drive motor 251 is rotated in the reverse rotation direction, the pump 253 for driving the feed pump that passes through the drive shaft of the crushing screw 231 operates, and the pump 261 is driven.
However, in order to forcibly discharge the crushed garbage sucked in from the pumping pump inlet 262 to the drain pipe from the pumping pump outlet 263, the garbage is rotated at a high speed of 1000 to 3000 rpm.
This can be performed by switching the transmission that transmits the rotation of the motor between forward rotation and reverse rotation.

The above crushing screw-231 is 30 to 1
The reason for the slow rotation at 50 rotations / minute is that the rotation speed lower than 30 rotations / minute is not practical in terms of the processing capacity of garbage, and the rotation speed higher than 150 rotations / minute is not suitable for the crushing of garbage. The noise increases, which is a practical problem in ordinary houses. On the other hand, if the rotation speed is high, the user's anxiety about injury is increased, which is not preferable.

As described above, the crushing and crushing by the slow rotation of the crushing screw-231 and the crushing of the garbage by the cutting by the rotary blade 241 can reliably realize the crushing quietly. Further, since the crushed garbage is forcibly discharged to the drainage pipe by the pressure pump 261, no clogging occurs in the horizontal drainage pipe.

Further, since the crushing means 23 and the pressure feeding means 26 are switched and driven by the same driving motor 251, the driving motor 251 can be reduced in power consumption and size.

In the above description, the pump 261 is rotated at high speed by the reverse rotation of the drive motor 251. However, a clutch mechanism is added to the transmission 252 to rotate the pump at high speed by forward rotation. Needless to say, it is good.

Further, in the technique described in Japanese Patent Publication No. Hei 7-18185, which is known as a conventional technique, crushing and transporting are performed in water, whereas in the present embodiment according to the present invention, crushing is performed underwater. Because it is not done in the form of sinking, energy consumption is small.

FIG. 2 is a longitudinal sectional side view showing a second embodiment of the kitchen waste treatment apparatus main body according to the present invention.

In FIG. 2, the garbage thrown in from the garbage inlet 21 and temporarily stored in the hopper 22 is crushed to a predetermined particle size by a crushing screw 231 and a rotary blade 241 via an appropriate amount of water. The garbage is conveyed from the opening of the plate 242 to the crushed garbage storage unit 27. Reference numeral 271 denotes a filter provided in the crushed garbage storage part 27, and drainage other than solid matter is discharged to the water storage tank 31 through the filter 271. The water storage tank 31 is provided with water level sensors 312 and 313 for detecting the water level of the stored water amount. After confirming the water level by the signals of the water level sensors 312 and 313, the pump 261 is operated to store the crushed garbage. Part 2
Sufficient water for pumping the garbage of No. 7 is sucked in from the pumping pump suction port 262, and is discharged from the garbage discharge port 311 through the pumping pump discharge port 263 to the drain pipe.

314 and 315 are crushed garbage storage units 2
7 shows the flow direction of the drainage water in the filter unit 271 provided in the filter 7. When water is supplied from the hopper 22, the filter unit 271 discharges water into the water storage tank 31 (3).
14), and is exposed to the inflow (315) of water from inside the water storage tank 31 when the pressure feed pump 261 operates. That is, the filter section 271 is always automatically cleaned before and after the operation of the pressure feed pump 261 and does not cause clogging. Further, since the present garbage disposal apparatus is provided with the water storage tank 31 and can perform a sufficient pressure feeding operation, the garbage after crushing and cutting can be transported without clogging in the horizontal drainage pipe.

Further, a drain port (drain valve) 400 for discharging the sediment stored therein together with water may be provided at the bottom of the water storage tank 31. The drainage port 400 is preferably provided not only in the present embodiment but also in the bottom of the water storage tank in other embodiments.

FIG. 3 shows a state where the kitchen waste treatment apparatus shown in FIG. 2 is installed on a sink.

In FIG. 3, the kitchen waste disposal apparatus is equipped with a sink 2
The sink 41 is attached to the lower part of the sink so as to be fitted to a drain port 42 provided in the sink 41 and is installed inside the sink 2.
At this time, the apparatus main body is installed so that the angle α between the crushing screw shaft and the floor surface is 20 to 70 degrees, preferably 30 to 60 degrees. The reason is that if it is smaller than 20 degrees, residues are likely to be generated in the case 232,
If it is larger than the degree, garbage will not easily enter the case 232 from the hopper 22.

The garbage consisting of kitchen garbage is a garbage input port 21.
And is stored in the hopper 22. When garbage has accumulated to a certain extent in the hopper 22, the drive motor 25
1, the garbage is crushed by the crushing screw-231 together with an appropriate amount of water from the water supply faucet 43, cut by the rotary blade 241 and discharged to the crushed garbage storage 27 located below. When it is confirmed by the water level sensors 312 and 313 that the crushing of the garbage in the hopper 22 is completed and the amount of water stored in the water storage tank 31 is sufficient, the pump 261 is provided.
Is operated, and the garbage in the crushed garbage storage section 27 flows through the drainage trap 44 connected to the garbage discharge port 311 via the pressure pump discharge port 263 and is discharged to the horizontal drainage pipe 4. Thereafter, the water is treated by a water treatment device (not shown) provided at an arbitrary place.

With the structure in which the water treatment device is provided separately from the kitchen waste treatment section main body, only the main body needs to be installed under the sink 2 and a wide space is not required, so that it can be easily installed on an existing sink. In addition, the faucet 43 for water supply contains a solenoid valve described later.

The normal washing wastewater flowing into the drain port 42 of the sink 41 of the sink 2 passes through the hopper 22, the crushing screw-231, the rotary blade 241 and the plate 242, and passes through the crushed garbage storage part 27. The water is stored in the water storage tank 31 from the filter unit 271. Before the garbage collects in the hopper 22 to some extent, the water storage tank 31 becomes full and the water level sensor 3
If the pump 12 detects that water is full,
1 to perform the flash pressure feed control at predetermined time intervals. Even when crushed garbage remaining in the horizontal drawing pipe 4 is present, the residual garbage can be wiped out by this flush pressure feeding. Furthermore, since the crushing screw-231, the rotary blade 241 and the plate 242 are always washed by the normal washing drainage, a bad smell due to the residue of the crushed garbage does not occur.

The distance from the bent portion of the hopper 22 to the case 232 is set such that the crushing screw 231 does not directly exist on the lower surface of the central portion 46 of the hopper 22. The drain cover 45 is provided with a hole at the center and a radial cut to allow garbage to fall from the center into the hopper. Thus, when a slender foreign object is introduced, the bent portion of the hopper 22 and the drain port cover 45 can prevent the foreign object from stopping and being introduced into the crushing screw-231. Also, when the crushing screw-231 crushes hard garbage such as chicken bones, even if crushed pieces of bone are scattered, the crushed pieces first strike the hopper 22 so that the crushed pieces go out of the garbage inlet 21. The probability of direct scattering can be kept low.

FIG. 4 is a block diagram showing a control system of the kitchen waste disposal apparatus according to the present invention. This control system is common to other embodiments not particularly described. Garbage processing control device 101 that receives power from main power supply 104 that is a commercial power supply
The motor 251 for driving the crushing screw 231, the rotary blade 241, and the pump 261, and the notification means 103 according to a command signal from the operation switch 102 and signals from the crushing completion detecting means 106 and the water level detecting means 107. The operation of the faucet solenoid valve 105 is controlled. Operation switch 1
Reference numeral 02 includes an operation button for a crushing switch (forward rotation), a stop operation button, and an operation button for a pressure pump switch (reverse rotation).

The control will be described with reference to FIGS. This kitchen garbage processing control device 101 operates when the garbage is put into the garbage input port 21 of the separation wall 52 of the hopper 22 from the drain port 42 of the sink 41 of the sink 2 and the garbage is stored in the hopper. When the crush switch button of the switch 102 is pressed, the drive motor 251 and the transmission 252 are rotated so that the drive motor 251 rotates in the forward rotation direction.
, And the electromagnetic valve 105 built in the water supply faucet 43 is opened to pour water into the sink 41. The crushing screw-231 and the rotary blade 24 are driven by the driving motor 251 and the transmission 252.
When 1 rotates at a low speed, the garbage thrown in is crushed by squeezing and crushing accompanying the transportation by the crushing screw-231, and is cut by the rotary blade 241 when passing through the opening of the plate 242 of the cutting means 24. And is discharged to the crushed garbage storage unit 27 together with the water. The discharged water is filtered
The water is stored in the water storage tank 31 through the portion 271. Then, when the crushing of the inputted garbage is completed, the crushing completion detecting means 106 detects the state and sends a signal to the control device 101, and the control device 101 stops the driving motor 251.
At this time, after confirming from the signal from the water level detecting means 107 of the water storage tank 31 that the water level is in a state that does not interfere with the pump operation, the control device 101 rotates the driving motor 251 so as to rotate in the reverse rotation direction. And pressurize the pump 2
61 is rotated at high speed. The garbage wastewater from the crushed garbage storage part 27 is drained through the drainage trap 44 by the pressure pump 261 and is forcibly drained to the horizontal drainage pipe 4. The pressure pump 261 is based on the signal of the water level detection means 107,
By performing flash pressure feeding that repeats the operation start-stop at predetermined time intervals (for example, at intervals of several seconds to several tens of seconds), the garbage wastewater is efficiently flowed without accumulating in the horizontal drainage pipe 4 for drainage. Can be discharged. That is, while the water level sensor 313 constituting the water level detection means 107 of the water storage tank 31 is detecting the water level, the pressure pump 26
When the controller 1 receives the signal indicating that the water level is not detected from the water level sensor 313, the controller 101 stops the drive motor 251 to stop the pumping operation, and the kitchen waste processing ends.

The amount of water stored in the water storage tank 31 becomes full with the normal washing water of the sink 2, and the control device 101
When receiving a signal from the water level sensor 312, the pump 261 is given priority regardless of the operation of the garbage crushing means.
Is started to perform flash pressure feeding. Next, when a signal indicating that the water level is not detected is received from the water level sensor 313, the drive motor 251 is stopped and the pressure feeding operation is stopped.

In the above description, the operation in the case where the water level sensors 312 and 313 having two levels of high and low levels are used as the water level detecting means 107 has been described. Pressure pump 261 after
May be started at the middle water level or higher and stopped at the low water level. Further, when the water storage amount of the water storage tank 31 becomes full, the operation of the pump 261 may be started at a high water level and stopped at a middle water level, so that it is possible to immediately cope with the subsequent garbage crushing operation.

Further, if it is desired to perform the pressure feeding in a state where the amount of water in the water storage tank is small, the water may be supplied from the drain port 42.

In addition, foreign matter other than garbage (for example,
When the stop operation button of the operation switch 102 is pressed when a spoon or fork is turned on, the control device 10
1 stops the drive motor 251.

The crushing completion detecting means 106 determines that the load on the drive motor 251 has been reduced.
The change is detected using the change in the operating current. The overload state of the drive motor 251 is used as a change in the operating current of the drive motor 251 to detect the intrusion of a foreign substance.
In addition to stopping the operation, the notification means 103 can notify the user of an abnormal alarm by sound or display.

FIG. 5 shows a third embodiment of the kitchen waste disposal apparatus according to the present invention.
It is a vertical side view which shows embodiment.

Note that the same components as those in the above-described embodiment are denoted by the same reference numerals, and redundant description will be omitted.

The waste water is discharged to the crushed garbage storage part 27 through the drainage tank 242, and is stored in the water storage tank 31 through the waste water bypass passage 51.
When the pump 1 is detected to be full, the pump 261 starts operating immediately, and is discharged from the pump outlet 263 through the drain trap 44 connected to the garbage outlet 311 and discharged to the horizontal drainage pipe. The sink does not overflow. Further, the hopper 22 for charging and temporarily storing the garbage has a double structure with a separation wall 52 having a plurality of openings for separating the inside for storing the garbage and the outside serving as a water flow path. The separation wall 52 is configured such that its cross-sectional area is the smallest at the garbage inlet 21 and becomes larger toward the inside of the hopper 22 (toward the crushing screw-231). The separation wall 52 is configured to be detachable from the hopper 22.

FIG. 7 is a longitudinal sectional view of the hopper 22 and the separation wall 52. The separation wall 52 is connected to the hopper-22.
The auxiliary drain port 221 is covered to prevent garbage from entering the auxiliary drain port 221. The garbage inlet 21 of the separation wall 52 is so small that the garbage cannot easily enter the inside of the hopper 22 and the garbage can easily enter the hopper 22, so that the safety against damage and the like is high.

The separation wall 52 is provided with a plurality of openings 521 so that the drainage can pass smoothly.

If foreign matter (spoon, fork, etc.) other than garbage is mistakenly put into the hopper, the operation switch (not shown) of the garbage disposal device is cut off, and After removing 52 from the hopper 22, the foreign matter is collected from inside the hopper by hand or a removal jig (not shown). After the foreign matter is collected, the separation wall 52 is mounted in the hopper 22.

In FIG. 8, 1 is an apartment house, 2 is a sink installed in a kitchen or the like of each home of the apartment house 1, a sink 2
A garbage disposal device 3 for crushing garbage such as garbage generated at home through water and forcibly pumping the garbage generated in the home is installed in the inside. In FIG. 8, the kitchen waste processing apparatus used in the first embodiment is used, but may be used in any of the embodiments. The crushed garbage is forcibly pumped together with the water, flows through the drainage horizontal draw pipe 4, and flows into the solid-liquid separation device 11 installed below the apartment house 1 or under the basement by the sink vertical discharge pipe 5. . In the solid-liquid separation device 11 (for example, a screw press or a belt press type solid-liquid separation device), garbage wastewater is separated into solid and liquid, and the water content is 80%.
The solid components of the garbage dehydrated below are transported to a composting treatment device 14 (for example, a microbial composting treatment device for fermenting and decomposing garbage by microorganisms), composted and recycled as fertilizer and soil improvement material. You. On the other hand, the wastewater separated by the solid-liquid separation device 11 is purified by a water treatment device 12 (for example, a microbial membrane type water treatment device or the like) so as to satisfy a sewage acceptance standard, and then sent to a storage tank 15 by a pump 13 to be miscellaneous. The water is discharged to the sewer pipe 16 together with the wastewater from the bath 6, the washing machine 7, etc. and the wastewater from the toilet 8 other than the sink drainage flowing into the storage tank 14 through the drainage / sewage horizontal drawing pipe 9 and the vertical pipe 10. . As a result, problems in hygiene and the environment can be solved, and the load on the sewage system does not increase. Garbage made up of kitchen waste and the like in each household is collectively processed by the solid-liquid separation device 11 and the composting treatment device 14, so that each household can process (disappear) it at one place. In addition, there is no need to carry out garbage, which has been a heavy burden for the elderly.

Particularly, in a multi-family house, since composting and water treatment can be performed collectively, only the garbage treatment apparatus main body is installed in a corner household, and it can be easily installed without taking up space. Can be.

The kitchen waste disposal apparatus according to the present invention comprises:
The crushing means, the cutting means, and the pressure-feeding means are integrally connected in a linear state, and the driving means drives the crushing screw of the crushing means, the rotary blade of the cutting means, and the pressure-feed pump of the pressure-feeding means, which are connected in series. By tilting the motor side so that it rises, the crushing screw and rotating blade are slowly rotated by the driving motor, so that garbage is crushed by squeezing and crushing in the process of being transported by the crushing screw. Flexible and tough garbage, which is not crushed by squeezing and crushing, is also cut to a size suitable for post-processing, discharged to the garbage storage section located below, and after crushing is completed, the garbage wastewater is drained by a pressure pump. Since the drainage pipe is forcibly discharged, the drainage pipe is not clogged, the operation is quiet, and
Due to the inclination, the overall length becomes short and small, so that a form suitable for being installed inside the sink can be obtained. And, by inputting and discharging the garbage together with the water, the residue can be hardly generated.

Further, since the crushing of garbage and the pumping operation of garbage wastewater are sequentially performed by the same drive motor, the drive motor has the advantage of low power consumption and small size. Further, since the driving motor is arranged at the upper part, there is an advantage in terms of reliability and safety for water sealing of drainage.

Further, since the used washing wastewater is stored in the water storage tank in the sink to be used for feeding the garbage wastewater and for flushing the drainpipe, it also has a water-saving effect and a drainpipe maintenance effect. ing.

The hopper for charging and storing the garbage is bent at the garbage input port side and the crushing screw side, and has a double structure with a separation wall having a plurality of openings. The cross-sectional area of the wall is the smallest at the garbage input port and increases toward the inside of the hopper, so that when garbage is crushed, the crushed garbage may be scattered to the outside, High safety because no damage occurs.

As in the above-described embodiment, with the same motor,
If the drive of the crushing screw as the crushing means and the drive of the pressure pump as the pressure feeding means are switched, a small-capacity motor can be used, and the size of the garbage disposal device can be reduced. Such miniaturization is particularly important for kitchen waste disposal devices that are placed in a narrow space below a sink.

[0076]

According to the present invention, by operating the crushing means and the pumping means at appropriate speeds respectively, the pressure required to pump the crushed garbage (garbage) downstream by the drain pipe is generated. In addition, it is possible to provide a garbage disposal device or a garbage disposal system that operates with low noise.

Further, it is possible to provide a small-sized garbage disposal apparatus or a garbage disposal system which can be easily installed on a kitchen sink in a general house and is useful for saving water.
