Description

Kitchen Waste Disposal Device {KITCHEN WASTE DEALING APPARATUS}

The present invention relates to a kitchen waste disposal apparatus for processing kitchen waste such as food waste.

Conventionally, kitchen wastes such as food waste are collected and stored in a garbage bag for each household, and transported and disposed of as combustible garbage to a garbage collection station on a predetermined collection day. The accumulated garbage is collected by local governments and disposed of by incineration or landfilling. However, perishable kitchen waste such as vegetable debris from the kitchen, meat, fish, leftover rice, etc., decay and smell during storage or collection, and have problems in terms of hygiene and environment. In addition, with the advent of an aging society, the removal of garbage on a regular basis has become a great burden, especially in high-rise houses such as apartment houses.

Disposer is attached to the bottom of kitchen sink drain in each household to dispose (disposal) of kitchen waste in the place where it is thrown, and the food waste put into the drain is crushed by the swing hammer which rotates at high speed and flows to the drain pipe along with water. It is becoming. In this case, when a large amount of food waste, such as an egg shell or a clam shell, is contained, or when the particle size at the time of crushing is large, there exists a possibility that crushed waste may settle in a horizontal drain pipe, and the clogging of a drain pipe may occur. In addition, the kitchen waste is crushed by a swing hammer that rotates at a high speed, so that noise and vibration during crushing are increased.

As one solution to these problems, food waste introduced from the inlet directly connected to the sink drain by a motor-driven cutter-attached impeller installed in a casing having an inlet and an outlet is cut to a size sufficient to pass through the drain pipe. As an indoor drainage system which cuts and feeds a drain pipe from an outlet, what is disclosed by Unexamined-Japanese-Patent No. 7-18185 is proposed.

In addition, one side (upper part) of the motor rotating shaft penetrating the motor main body is connected to sink sink drains, and a crushing part for crushing and liquefying food debris in the drainage is provided, and the food waste mixed in the liquid state (lower part) is mixed. As a crushing-feeding apparatus provided with the feed-feeding part which feeds waste water, and the food waste crushing-feeding apparatus which used the feed pipe, what is disclosed by Unexamined-Japanese-Patent No. 6-45495 is proposed.

Although each device described in Japanese Patent Application Laid-open No. Hei 7-18185 and Utility Model No. Hei 6-45495 has the advantage of being able to dispose of kitchen waste at the place where it is generated and to prevent clogging of the drain pipe by being pumped, Since the high-speed rotation operation for crushing and conveying food waste is performed at the same time, there is a problem that the noise during crushing food waste becomes large.

Accordingly, an object of the present invention is to provide a kitchen waste disposal apparatus or a kitchen waste disposal system which is smoothly conveyed crushed food waste (kitchen waste) from the drain pipe downstream, and operated with low noise.

In order to achieve the above object, the kitchen waste processing apparatus of the present invention comprises a shredding means for shredding the kitchen waste put into the inlet, a storage for storing the kitchen waste shredded by the shredding means, and kitchen waste stored in the storage Pressure feeding means for feeding the pressure into the drain pipe, and driving means for driving the pressure feeding means and the crushing means at different rotational speeds.

More preferably, the crushing means has a crushing screw for crushing the kitchen waste fed from the inlet, a storage unit for storing kitchen waste crushed by the crushing means, and a pressure feeding unit for conveying the kitchen waste stored in the storage unit into a drain pipe. And a driving means having a pump and a driving motor for driving the pump and the crushing screw at different rotational speeds.

In the above configuration, by operating the rotational speed of the crushing screw and the rotational speed of the pressure pump each at an appropriate rotational speed, the crushing operation by the crushing screw is quieted, and the pressure-feeding pump can generate the necessary pressure force. At this time, the operation rotation speed of the crushing screw is usually made low to reduce the noise during the kitchen waste crushing operation, and the operation speed of the pressure pump can be made high to achieve the sufficient feeding performance. Thereby, kitchen waste conveyance in a drain piping can be performed smoothly, and a drain pipe becomes difficult to be clogged. Moreover, by rotating the crushing screw at a low speed, hard kitchen waste such as chicken bones can be easily processed.

At this time, the drive means may be driven by switching the crushing screw and the pressure pump with the same drive motor.

In this case, since the pressure pump and the crushing screw do not operate at the same time, it is possible to operate in a small drive motor with a small capacity.

Moreover, what is necessary is just to arrange the rotation center of the said crushing screw and the said pressure pump on the rotation axis of the said drive motor.

Moreover, what is necessary is just to arrange | position in order for a drive means, a crushing means, and a pressure pump from upper direction along the rotation axis of the said drive motor.

Moreover, in the kitchen waste disposal apparatus which concerns on this invention, the said crushing screw may rotate at 30-150 rotation / min, and the said pressure pump may be rotated at 1,000-3,000 rotation / min.

In each of the kitchen waste disposal apparatuses described above, a storage tank may be provided, and the feeding means may feed the kitchen waste together with the water of the storage tank to the drain pipe. Thereby, kitchen waste can be conveyed by sufficient quantity, kitchen waste in a drain pipe can be conveyed smoothly, and a drain pipe becomes difficult to be clogged.

At this time, the reservoir tank may be configured to store the fluid flowing from the inlet. As a result, the water storage tank can store and use the washing drainage water in the sink, and thus, it is not necessary to use tap water in order to pump the water, thereby saving water.

At this time, if the water is supplied from the reservoir to the reservoir tank and is absorbed by the reservoir from the reservoir by the driving means, the filter is provided between the reservoir and the reservoir. good. In the filter installed in the reservoir, the flow of water is reversed at the time of drainage to the reservoir tank and at the time of the pump operation, so that the filter is always automatically cleaned and clogging can be made difficult.

Moreover, in the kitchen waste disposal apparatus provided with a water storage tank, you may provide the bypass flow path which connects this hopper and the water storage tank in the middle of the hopper which connects between the said inlet and the case interior containing the said crushing screw.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described based on drawing.

BRIEF DESCRIPTION OF THE DRAWINGS It is a longitudinal side view which shows 1st Embodiment of the kitchen waste disposal apparatus main body of this invention.

In Figure 1, 21 is a kitchen waste inlet for inputting the kitchen waste consisting of food waste generated in the kitchen with an appropriate amount of water, 22 is a hopper for temporarily storing the introduced kitchen waste, 23 is a kitchen in the hopper 22 A plurality of openings, which are crushing means for crushing the trash, crushing the kitchen trash by pressing and pulverizing while conveying downward by slow rotation of the crushing screw 231, and constituting the crushed kitchen trash as the cutting means 24. When pushed downward through the plate 242 having a short cutting by the rotating blade 241 to move while pressing the plate 242. The cutting means 24 cuts and cuts flexible and tough kitchen waste such as squid shells, chicken shells, corn husks, etc., which cannot be crushed by the crushing screw 231 to a predetermined size and plate 242. It pushes out into the crushed kitchen waste storage part 27 located below from the some opening 243 provided in the inside. Reference numeral 26 denotes a conveying means for forcibly conveying the crushed kitchen waste to the drain pipe together with water. The crushed kitchen waste sucked from the feed pump inlet 262 by the high speed rotation of the feed pump 261 is the feed pump discharge port 263. Is forced out of the drain pipe.

Each of the above means is provided in the order of crushing means, cutting means, storage portion, and conveying means from above on the rotation axis of the drive motor 251 to be described later, and the rotating shaft or the crushing screw shaft of the drive motor 251 is inclined. .

In this embodiment, the crushing screw shaft is installed at an angle with respect to the floor surface, and since the crushing screw is located above the rotating blade and the plate, the kitchen waste is fed from the crushing screw to the rotating blade from above and downward, so that the kitchen waste is It can convey to a rotating blade and a plate without stopping in the middle. Therefore, residual debris (crushed kitchen debris) is less likely to occur in the case 232, the crushing screw 231, and the plate 242. Moreover, since water also flows together, it becomes difficult to produce residual residue. Therefore, the odor by residual residue can be almost prevented.

25 is a drive means, it slows down the crushing screw 231 and the rotating blade 241 installed in series at 30 to 150 rotations / minute, and rotates the said pressure pump 261 at 1,000 to 3,000 rotations / minute at high speed. And a reversible rotary drive motor 251 and a transmission 252. In the present embodiment, the drive motor 251 is provided on the upper side due to the ease of waterproofing or the like. However, the drive motor 251 may be provided on the pump side or installed in another place depending on the space, etc., to drive the belt.

The hopper 22 is bent between the kitchen waste inlet 21 side and the opening (connection) into the case 232 in which the crushing screw 231 is housed, and the bend angle β is set to 140 to 170 degrees. Thereby, the kitchen waste thrown in in the hopper is certainly blown into the crushing screw 231 without remaining in the middle of the hopper and crushed. If the bend angle of the hopper is too small, the introduced kitchen waste easily becomes stagnant at the bent portion, and there is a fear of blockage in the hopper. For this reason, it is preferable that a bending angle shall be about 140 degree or more. As described above, the rotating shaft of the crushing screw 231 is installed to be inclined at an angle of 20 to 70 degrees with respect to the floor surface or the horizontal surface, but if the bending angle is larger than 170 degrees, the opening on the crushing screw 231 side Cannot be made large, the effective crushing part of the crushing screw 231 is shortened, and the crushing function is reduced.

In addition, by properly bending the hopper, the normal kitchen waste reaches the crushing screw without being blocked by the hopper, but when a large and long foreign object is accidentally introduced into the hopper, it stops by hitting the hopper, thus preventing direct penetration into the crushing screw. can do. In addition, even if the crushing screw scatters the debris during the crushing of the hard kitchen waste, there is no inlet on the straight line of the crushing screw, and since it collides with the hopper first, it may be difficult to protrude directly from the kitchen waste inlet to the outside.

In addition, the internal volume in the hopper 22 is large enough to store a day's kitchen waste generated at home.

When the drive motor 251 rotates in the forward rotation direction, the shredding means 23 in the kitchen waste disposal apparatus has the shredding screw 231 driven by the drive motor 251 and the transmission 252 for the kitchen waste inlet ( Slowly rotate at 30 to 150 revolutions / minute to convey the kitchen waste introduced from 21) in the lower right direction in the figure. The kitchen waste conveyed by the crushing screw 231 is crushed by pressing and crushing between the crushing screw 231 and the case 232. Then, when it is sent from the opening of the plate 242 to the crushed kitchen waste storage 27, it is shortly cut by the rotating blade 241 that rotates while pressing and moving with the plate 242. This foundation shortly cuts flexible, thin and long kitchen wastes such as crushed shells and stems contained in the kitchen wastes that are crushed by pressing and crushing.

Subsequently, when the drive motor 251 is rotated in the reverse rotation direction, the pressure pump driving shaft 253 penetrating the drive shaft of the crushing screw 231 is operated, and the crushing pump suctioned from the pressure pump suction port 262 by the pressure pump 261 is operated. The kitchen waste is rotated at a high speed of 1,000 to 3,000 revolutions / minute to forcibly discharge the kitchen waste from the pressure pump discharge port 263 to the drain pipe. This can be done by switching the transmission which transmits the rotation of the motor at the time of forward rotation and reverse rotation.

In addition, the reason for slowly rotating the shredding screw 231 at 30 to 150 revolutions / minute is not practical in terms of processing capacity of kitchen waste at a rotation speed slower than 30 revolutions / minute, and at a rotation speed faster than 150 revolutions / minute. Noise during shredding of kitchen waste becomes large, and becomes a practical problem in a general house. In addition, a high rotational speed increases anxiety for the user from hurting and is undesirable.

Thus, the crushing and grinding of the crushing screw 231 by slow rotation and the crushing of the kitchen waste by the cutting in the rotary blade 241 can be realized reliably and quietly. In addition, since the crushed kitchen waste is forcibly discharged to the drain pipe by the pressure feed pump 261, no blockage occurs in the horizontal drain pipe.

In addition, since the crushing means 23 and the feeding means 26 are driven by the same driving motor 251 to drive each other, the driving motor 251 can be miniaturized with low power consumption.

In addition, although the high speed rotation operation | movement is performed by the reverse rotation of the drive motor 251 in the above-mentioned description, you may add a clutch mechanism to the transmission 252, and operate the high speed rotation operation | movement by the forward rotation of the pressure pump. Of course.

In addition, in the technique described in Japanese Patent Application Laid-open No. Hei 7-18185, which is known as a prior art, crushing and conveying are carried out in water, whereas in the present embodiment according to the present invention, crushing is not performed in the submerged form. Energy can also be made small.

Fig. 2 is a longitudinal side view showing the second embodiment of the main body of the kitchen waste disposal apparatus of the present invention.

In Fig. 2, the kitchen waste, which is introduced from the kitchen waste inlet 21 and temporarily stored in the hopper 22, is crushed to a predetermined granularity by the crushing screw 231 and the rotating blade 241 through an appropriate amount of water, and the plate It is conveyed to the kitchen waste storage part 27 crushed from the opening of 242. 271 is a filter part installed in the crushed kitchen waste storage part 27, and waste water other than solid content is discharged | emitted to the water storage tank 31 through the filter part 271. The reservoir tank 31 is provided with water level sensors 312 and 313 for detecting the low water level. After checking the water level by the signals of the water level sensors 312 and 313, the pressure pump 261 is operated. In addition, water sufficient to pump the kitchen waste of the crushed kitchen waste storage unit 27 is sucked from the pump pump inlet 262, and is discharged from the waste outlet 311 to the drain pipe through the pump pump outlet 263.

314 and 315 represent the flow direction of the drainage in the filter part 271 provided in the crushed kitchen waste storage part 27, and the filter part 271 is a water storage tank when water is supplied from the hopper 22. It is exposed to the discharge 314 of water into the 31, and is exposed to the inflow 315 of the water from the reservoir tank 31 during the operation of the pressure pump 261. That is, the filter portion 271 is automatically cleaned before and after the operation of the pressure feed pump 261 so that clogging does not occur. Moreover, since this kitchen waste disposal apparatus is equipped with the water storage tank 31, and can perform a sufficient conveying operation, the kitchen waste after crushing and cutting can be conveyed without a blockage in a horizontal drain pipe.

Further, a drain port (drain valve) 400 for discharging the deposit stored therein with water may be provided at the bottom of the reservoir tank 31. The drain 400 is not limited to this embodiment, but is preferably provided at the bottom of the water storage tank of another embodiment.

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

In FIG. 3, the kitchen waste disposal apparatus is attached to the lower part of the sink so as to be coupled to the drain hole 42 provided in the sink 41 of the sink 2, and is installed inside the sink 2. At this time, the apparatus main body is installed such that the angle α formed by 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, residual debris tends to occur in the case 232, and if it is larger than 70 degrees, it becomes difficult for kitchen waste to enter the case 232 from the hopper 22.

The kitchen waste consisting of food waste or the like is put into the kitchen waste inlet 21 and stays in the hopper 22. When the kitchen waste is collected to some extent in the hopper 22, the drive motor 251 is started to operate, and the kitchen waste is crushed by the crushing screw 213 together with the appropriate amount of water from the water supply faucet 43, It is cut by the rotary blade 241 and discharged to the crushed kitchen waste storage unit 27 located below. When the crushing of the kitchen waste in the hopper 22 is completed and the storage water amount of the storage tank 31 is confirmed by the water level sensors 312 and 313, the kitchen waste storage unit 27 that is crushed by operating the pressure pump 261. Kitchen wastes are discharged to the drainage drainage pipe (4) via the drain pump (263) through the drain trap (44) connected to the kitchen waste outlet (311). Thereafter, the treatment is performed by a water treatment apparatus (not shown) installed in an arbitrary place.

With the structure in which the water treatment apparatus is installed separately from the main body of the kitchen waste disposal unit, only the main body may be installed below the sink 2, and since a large space is not needed, it is easy to install in an existing sink. In addition, the water supply faucet 43 incorporates a solenoid valve described later.

The normal cleaning drainage flowing into the drain 42 of the sink 41 of the sink 2 is kitchen waste shredded through the hopper 22, the shredding screw 231, the rotary blade 241, and the plate 242. The water is collected in the water storage tank 31 from the filter portion 271 of the storage portion 27. If the reservoir tank 31 is full and the water level sensor 312 detects full water before the kitchen waste is collected in the hopper 22 to some extent, the pressure pump 261 is operated immediately and flashes at a predetermined time interval. Pressure control is performed. Even in the case where the shredded kitchen waste remaining in the cross pipe 4 exists, the residual kitchen waste can be erased by this flash feeding. Moreover, since the crushing screw 231, the rotating blade 241, and the plate 242 are always cleaned by the normal washing | cleaning drainage, the odor by the residual residue of the crushed kitchen waste does not generate | occur | produce.

The distance from the bent portion of the hopper 22 to the case 232 is such that the crushing screw 231 does not exist directly on the lower surface of the central portion 46 of the hopper 22. In addition, the drain cover 45 is provided with a hole in the center to form a radial cut, so that kitchen waste and the like fall from the center into the hopper. As a result, when the elongated foreign matter is introduced, the foreign matter is stopped by the bent portion of the hopper 22 and the drain cover 45, thereby preventing the foreign matter from being introduced into the crushing screw 213. In addition, when the crushing screw 231 crushes hard kitchen waste such as chicken bones, even when the crushed pieces of bone are scattered, the crushed pieces first collide with the hopper 22, so that they are directly outside the kitchen trash inlet 21. The probability of scattering can be reduced.

4 is a block diagram showing a control system of the kitchen waste disposal apparatus of the present invention. This control system is common to other embodiments not specifically described. The kitchen waste disposal control apparatus 101 which receives electricity from the main power supply 104 which is a commercial power supply is provided with the command signal from the operation switch 102, the crush completion detection means 106, and the signal from the water level detection means 107. Therefore, the operation of the crushing screw 213, the rotary blade 241, the pressure pump 261 driving motor 251, the alarm means 103, and the faucet solenoid valve 105 is controlled. The operation switch 102 includes an operation button for the crushing switch (forward rotation), a stop operation button, and an operation button for the pressure pump switch (reverse rotation).

Control will be described based on FIG. 1 and FIG. This kitchen waste disposal control apparatus 101 puts kitchen waste into the kitchen waste inlet 21 of the partition wall 52 of the hopper 22 from the drain 42 of the sink 41 of the sink 2, and the hopper When the crush switch button of the operation switch 102 is pressed when the kitchen waste is stored in the kitchen waste, the driving motor 251 and the transmission 252 are pressed to rotate the driving motor 251 in the forward rotation direction, The solenoid valve 105 incorporating the faucet 43 is opened to inject water into the sink 41. When the crushing screw 231 and the rotary blade 241 rotate slowly when driven by the driving motor 251 and the transmission 252, the injected kitchen waste is crushed and crushed by the conveying by the crushing screw 231. As it is crushed and passed through the opening of the plate 242 of the cutting means 24, it is cut by the rotary blade 241 and discharged to the crushed kitchen waste storage 27 with water. The discharged water is collected in the reservoir tank 31 through the filter portion 271. Subsequently, when the crushing of the put-in kitchen waste is completed, the crushing completion detecting means 106 detects a state and sends a signal to the control device 101, and the control device 101 stops the drive motor 251. At this time, after confirming that the water level state is not impaired in the pump operation by the signal from the water level detecting means 107 of the water storage tank 31, the control device 101 rotates in the reverse rotation direction. 251 is pressed and the pressure pump 261 is rotated at high speed. The kitchen waste drainage of the kitchen waste storage unit 27 crushed by the pressure pump 261 is forcibly drained to the drain drain horizontal pipe 4 via the drain trap 44. The pump pump 261 performs the flash feeding by repeating the operation start-stop at a predetermined time interval (for example, several seconds to several tens of seconds) based on the signal of the water level detecting means 107, thereby eliminating kitchen waste. The drainage can be efficiently discharged without accumulating in the shed 4 for drainage. That is, while the water level sensor 313 constituting the water level detecting means 107 of the water storage tank 31 detects the water level, the pressure pump 261 continues the flash pressure feeding operation, and the water level sensor 313 Upon receiving the signal in the state of not detecting the water level, the control device 101 stops the drive motor 251 and stops the feeding operation, thereby ending the kitchen waste processing.

When the water storage tank 31 is filled with water by the normal washing water of the sink 2 and the control device 101 receives a signal from the water level sensor 312, the operation of the crushing means of the kitchen waste Irrespective of the flash pressure, the pressure pump 261 is started to operate first. Subsequently, upon receiving a signal in the state of not detecting the water level from the water level sensor 313, the driving motor 251 is stopped and the pressure feeding operation is stopped.

In the above description, the operation has been described for the case where the water level sensors 312 and 313 of the two levels are used as the water level detecting means 107. However, the kitchen garbage is crushed using the water level sensor of the high, medium and low levels. The operation of the pressure feed pump 261 after the operation may be performed at the medium level or higher and the operation may be stopped at the low level. In addition, when the amount of water stored in the water storage tank 31 becomes full, the pressure pump 261 may be operated at a high water level, and may be stopped at a medium water level to immediately respond to subsequent kitchen waste crushing operation.

If water is to be pumped in a state where the amount of water in the water storage tank is low, water may be supplied from the drain port 42.

In addition, if the stop operation button of the operation switch 102 is pressed when a foreign object (for example, a spoon or a fork, etc.) other than the kitchen waste is accidentally pressed, the control device 101 stops the drive motor 251. .

The crushing completion detecting means 106 detects the change of the operating current of the drive motor 251 by reducing the load of the drive motor 251. In addition, the overload state of the drive motor 251 is used to detect the mixing of foreign matters as a change in the operating current of the drive motor 251, stops the drive motor, and sounds or displays an abnormal alarm by the alarm means 103. It may also notify the user by.

The kitchen waste stored in the hopper 22 is crushed by the crushing screw 231 together with the water and discharged to the crushed kitchen trash storage 27. The discharged kitchen waste drainage is separated by the filter part 271, and only the drainage water is sent to the storage tank suction / drainage port 316 of the storage tank 32 separately installed from the storage part suction / drainage port 272 and stored. When the crushing of the kitchen waste is completed and the amount of water stored in the water storage tank 32 is an operable amount of the pressure pump (for example, the water level sensor 313 detects the water level), the pressure pump 261 is operated. The kitchen waste water is discharged to the horizontal drainage pipe 4 through the drain trap 44 connected to the pressure pump discharge port 263.

In the configuration shown in Figs. 2 and 3, by inserting the pressure pump section into the water storage tank, the effect of saving space and unnecessary piping between the tank and the pump can be expected. There is an effect of facilitating.

In Fig. 6, a drain drain 221 is provided in a part of the hopper 22 for storing the put kitchen waste and communicates with the auxiliary drain inlet 317 provided in a part of the reservoir tank 31. The passage 51 is provided. When a large amount of water is disposed of in the sink 41 of the sink 2 at the same time, it is discharged to the shredded kitchen waste storage 27 through the shredding screw 231, the rotating blade 241, and the plate 242. When the water storage tank 31 is stored in the water storage tank 31 through the drain bypass passage 51 and the water storage tank 31 is detected to be full by the water level sensor 312, the pressure feeding pump 261 starts to operate and the pressure feeding pump It is discharged from the discharge port 263 via the drain trap 44 connected to the kitchen waste discharge port 311 to the flow drain drain horizontal pipe, and the sink does not overflow. In addition, the hopper 22 for inputting and temporarily storing kitchen waste has a double structure by a separating wall 52 having a plurality of openings for separating the inside for storing kitchen waste and the outside serving as a flow path of water. The partition wall 52 is configured such that its cross-sectional area is the smallest in the kitchen waste inlet 21 and becomes larger toward the inside (the shredding screw 231 side) of the hopper 22.

If foreign matter (spoons, forks, etc.) other than kitchen waste is accidentally introduced into the hopper, after cutting the operation switch (not shown) of the kitchen waste disposal apparatus, the separating wall 52 is removed from the hopper 22. After removing, the foreign matter is recovered from the hopper by a hand or a drawing jig (not shown). After separating the foreign matter, the separating wall 52 is mounted in the hopper 22.

8 is a schematic configuration diagram of a kitchen waste disposal system showing an embodiment to which a kitchen waste disposal apparatus according to the present invention is applied.

In Fig. 8, 1 denotes a collective house, 2 denotes a sink installed in the kitchen of each household of the collective house 1, and inside the sink 2, kitchen waste such as food waste generated in the household is crushed through water and forced. The kitchen waste disposal apparatus 3 for conveying by the water is provided. In FIG. 8, although the kitchen waste disposal apparatus used for 1st Embodiment is used, it may be used for any embodiment. The crushed kitchen waste is forcibly conveyed together with the water, and the solid-liquid separation device 11 installed under the stairs or under the stairs of the collective house 1 by the drainage drainage pipe 5 through the drainage drainage pipe 4. Inflow). In the solid-liquid separation device 11 (for example, a screw press or a belt press type solid-liquid separation device, etc.), the kitchen waste drainage is solid-liquid separated, and the solid component of the kitchen waste drained at a water content of 80% or less is composted treatment unit 14. (For example, a microbial method composting apparatus for fermentation and decomposition of kitchen waste by microorganisms), and then composted and recycled as a fertilizer or soil improving material. On the other hand, the wastewater separated by the solid-liquid separation device 11 is purified by the water treatment device 12 (for example, a microbial membrane type water treatment device, etc.) to a state that satisfies the sewerage acceptance criteria, and then the pump 13 To the storage tank 15, and to the waste water tank and the toilet other than the drainage drainage which flows into the storage tank 15 through the horizontal pipe 9 and the vertical pipe 10 for the waste water and contaminated water 10, the washing machine 7, etc. It discharges to sewer pipe 16 with the sewage of (8). As a result, problems in the sanitary and environmental aspects can be solved, and the load on the sewerage is not increased. Since the kitchen waste which consists of food waste etc. of each household is processed by the solid-liquid separation apparatus 11 and the composting processing apparatus 14 collectively, it can be processed (decayed) in one place in each household. In addition, there is no need of taking out garbage which was a big burden for the elderly.

In particular, in a communal house, composting treatment and water treatment can be collected and performed, the only thing installed in each home is the kitchen waste disposal apparatus, and can be easily installed without occupying a place.

The kitchen waste disposal apparatus of this invention combines a drive means, a crushing means, a cutting means, and a conveying means so that it may be integrated in a linear state, and is connected to the crushing screw of the crushing means connected in series, the rotary blade of the cutting means, and the pressure pump of the conveying means. The drive motor side of the drive means is inclined so as to be high, and the crushing screw and the rotating blade are slowly rotated by the drive motor to crush the kitchen waste by pressing and pulverizing during the conveying process by the crushing screw, In the pulverization, flexible and tough kitchen waste, which is not shredded, is also cut to a size suitable for post-treatment and discharged to the kitchen waste storage unit located below, and after the crushing is completed, the kitchen waste drainage is forcibly discharged to the drain pipe by a pressure pump. As it is constitution, clogging of drain pipe does not occur, and operation Ladies and also by being inclined with a short total length is small, it can be in a form suitable for installing therein a sink. In addition, residual garbage can be made less likely by injecting and discharging kitchen waste together with water.

Further, since the crushing of the kitchen waste and the feeding operation of the drainage of the kitchen waste are sequentially performed by the same drive motor, the drive motor has an advantage of being compact with low power consumption. Moreover, since the drive motor is arranged in the upper portion, it has an advantage in terms of reliability and safety in sealing the drainage water.

In addition, since the washing and draining water used in the sink is stored in the water storage tank and used for the pumping of kitchen waste drainage and the flash cleaning of the drainage pipe, it also has a water saving effect and a maintenance effect of the drainage pipe.

In addition, the hopper for storing and putting kitchen wastes has a configuration that is bent at the kitchen waste inlet side and the crushing screw side. Furthermore, the hopper has a double structure by a separating wall having a plurality of openings. Since it is configured to be the smallest at the kitchen waste inlet and grows toward the inside of the hopper, safety is high because no scattering of shredded kitchen waste to the outside or damage of a finger due to misinsertion occurs during kitchen waste shredding.

As in the above-described embodiment, when the crushing screw drive serving as the crushing means and the pump feeding pump serving as the conveying means are switched with the same motor, a small capacity motor can be used and the kitchen waste disposal apparatus can be miniaturized. Such miniaturization is particularly important in kitchen waste disposal apparatuses arranged in a narrow space under the sink.

According to the kitchen waste disposal apparatus which concerns on this invention, while operating a crushing means and a conveying means respectively at an appropriate speed, it produces | generates the pressure required to convey the crushed food waste (kitchen waste) downstream from a drain pipe, and is operated with low noise. A kitchen waste disposal apparatus or kitchen waste disposal system can be provided.

In addition, it is possible to provide a small kitchen waste disposal apparatus or a kitchen waste disposal system that can be easily installed in a sink of a kitchen in a general house and also helps water saving.
