Description

Food waste processing device

The present invention relates to a food waste processing apparatus for processing food waste discharged from a kitchen or the like. As a food waste treatment device discharged from a kitchen or the like, the present applicant has applied for a food waste treatment device for processing by crushing, dehydrating and microbial decomposition while continuously feeding food waste in Japanese Patent Application Laid-Open No. 6-296550.

The food waste treatment apparatus has advantages in that the crushing of the food waste performed while watering, the dehydration of the crushed liquid food waste, and the decomposition by the microorganisms of the dehydrated crushed waste are continuously performed. In the process of dehydrating the waste, there is a problem that the fine waste pulverized is mixed in the drainage discharged by dehydration, thereby deteriorating the water quality of the waste.

It is also conceivable to install a dewatering filter and reduce the hole of the dewatering filter in order to reduce the incorporation of fine waste in the drainage. However, the hole of the filter is likely to be clogged and the filter must be frequently cleaned or replaced.

In addition, in such a food waste treatment apparatus, the carrier is agitated by a stirring blade provided inside the microorganism decomposition unit in order to satisfactorily decompose the food waste by the microorganisms.

However, as the carrier is stirred, the viscosity of the carrier is increased due to the water contained in the waste or decomposed water generated when the waste is decomposed, and the carrier adheres to the stirring blade. Therefore, the carrier is lifted by the stirring blade and moves forward in the rotational direction of the stirring blade. As a result, there was a possibility that the carrier with increased viscosity was pushed to the decomposition part inlet for transporting the waste into the microbial decomposition part, thereby blocking the decomposition inlet.

In addition, according to the present inventors' study, when the waste and the microbial carrier are agitated, for example, the microbial carrier is subdivided and the water passages are blocked, so that the decomposed water is not discharged from the decomposition vessel, and the decomposition capacity is significantly reduced. .

In addition, according to the inventor's examination, since the above-mentioned decomposed water is a small amount, it does not flow vigorously to the drainage channel, and since this decomposed water contains a viscous slimy component and a microorganism carrier, this slippery component It has been found that a problem occurs that the drainage of decomposed water deteriorates when the back is deposited in the drainage path.

Accordingly, a first object of the present invention is to prevent deterioration of wastewater without using a dewatering filter in a food waste treatment apparatus.

A second object of the present invention is a waste disposal apparatus for agitating a carrier inserted into a microbial decomposition unit by means of a stirring blade, wherein a decomposition inlet for transporting waste into the microbial decomposition unit by a carrier moved by agitation. It is to provide a waste disposal apparatus that can prevent the clogging.

A third object of the present invention is to improve the drainage of decomposed water by reducing the clogging of water passage holes.

A fourth object of the present invention is to prevent deterioration of drainage of decomposed water due to deposition of slim components and the like.

Therefore, the present invention focuses on the fact that the fine waste pulverized in the waste water is not mixed by pulverizing the water in the food waste to be put in advance, and thus does not cause deterioration of the water quality of the waste water. In order to achieve, in the invention of Claims 1 to 18, the food waste has an inlet to which the food waste is introduced, the water draining unit for removing water from the waste introduced from the inlet and substantially separating the water mixed in the waste from the waste, A microbial carrier carrying microorganisms on the drainage path for draining the water separated from the trash in this drainage part, a pulverization part for directly pulverizing the waste drained from the drainage part by a pulverization rotor, and the waste discharged from the pulverization part. A microbial decomposition unit for decomposition by means of a microbial decomposition unit, and agitation blades for stirring the microbial carriers , And the decomposition gas generated in the multiple of the multiples from the biodegradable portion, wherein with a discharge pipe for discharging to the outside.

As a result, the food waste containing water introduced from the inlet is pulverized in advance and then pulverized in the crushing unit and transferred to the microbial decomposition chamber. The crushed waste transported to the microbial decomposition unit is decomposed into odorless and harmless gases (CO ₂ and H ₂ O) in the microbial decomposition unit, and the waste gas discharged from the decomposition gas and the drainage channel is discharged to the outside through the discharge pipe. Therefore, since the water in the food waste fed from the inlet is discharged to the drainage path before grinding, there is no mixing of the crushed fine waste in the drainage discharged to the outside through the drainage path. , The water quality of drainage is kept good.

In particular, according to the invention of claim 2, the water draining portion is formed in a tubular shape, and a drainage hole is formed in the peripheral wall surface of the water draining portion for draining water to the discharge passage. It is located at and has a blocking member for communicating between the inlet and the grinding rotor, the blocking member between the inlet and the crushing unit to block the food waste introduced from the inlet to the top of the blocking member, and flows out of the drain hole. By draining the water out around the crushing unit, drain the food waste from the inlet, and when the trash runs out, the blocking member communicates between the inlet and the crushing unit. Doing.

That is, the water mixed with the trash flows out around the crushing unit through the drainage hole, thereby draining the water of the food waste introduced from the inlet. At this time, since the blocking member blocks the water draining part and the crushing part, water can be prevented from flowing into the crushing part. As a result, the degradation of the decomposition performance of the microorganisms in the microorganism decomposition unit can be suppressed.

In the invention of claim 4, the blocking member is provided below the inlet and has a spherical shape protruding upward.

As a result, the water can easily flow out of the drain hole formed in the peripheral wall surface of the blocking member in a state where the water extraction portion and the crushing portion are blocked by the blocking member.

In particular, the invention according to claim 6 is characterized in that the food waste processing apparatus is provided with a removal unit for removing the food waste deposited on the upper surface of the blocking member from this upper surface to transfer the food waste having been drained to the pulverization unit. .

Thereby, the waste water reliably can be conveyed to a grinding | pulverization part. Therefore, it is possible to prevent the smell of the garbage remaining on the upper surface of the blocking member to corrode.

In particular, in the invention of claim 7, the food waste processing apparatus is provided with an operation unit for blocking or communicating with the blocking member, and the blocking member is configured to be operated by the user's own operating force through the operating unit.

In particular, in the invention of claim 8, the operation portion is arranged at a lower portion of the kitchen cabinet and is characterized by being configured with a pedal pedal.

In this way, when the pedal is operated with the foot, both hands of the user are empty, so that it is easy to perform other tasks. In addition, since the pedal is disposed at the lower part of the kitchen cabinet, the user is easy to operate with his feet.

Particularly, in the invention of claim 9, the food waste processing apparatus stops the pulverization processing of the pulverization unit when the communication between the inlet and the crushing unit is in communication with the operation unit, and the operation unit is blocked between the inlet and the crushing unit. It is characterized by being configured to grind when there is.

As a result, foreign matters and the like can be prevented from entering into the crushing unit during the pulverizing treatment, and the pulverizing treatment can be satisfactorily performed.

Particularly, in the invention of claim 10, if the communication between the inlet and the crushing part is made by operation of the operation unit during the pulverizing process in which the pulverizing rotor is operated, the pulverizing motor which gives the stop power to the pulverizing motor which rotates the crushing rotor is supplied It is characterized by stopping the.

In other words, if the operation unit is operated while the grinding rotor is in operation and communication between the inlet and the grinding unit is made, the grinding process is stopped as in the invention of claim 9, so that the grinding rotor is cut off by, for example, interrupting the energization of the grinding rotor. You can stop it.

However, since the grinding rotor rotates by inertia only by communicating between the inlet and the pulverizing unit and intercepting the filling of the pulverizing rotor, the waste of the pulverizing unit may scatter from the inlet.

Therefore, in the invention of Qingsu Port 10, when the communication port and the grinding part communicate with each other during the grinding process, the grinding motor is supplied with a stop power supply to reduce the influence of inertia, and the grinding motor is stopped for a short time. You can. As a result, it is possible to prevent garbage from flying out from the inlet in advance.

By this, the waste excluding the water is pulverized by the fixed blade of the grinding rotor by the rotation of the grinding rotor, but is again crushed by the guide plate installed inclined at a predetermined angle on the inner wall of the fixed blade, and the grinding rotor and the fixed blade of the Since the pulverized waste is pushed out and dropped from the gap, especially in the case of dry grinding of the waste, the pulverization processing capability is improved.

Particularly, in the invention of claim 13, the crushing unit has a conveying tube for conveying the pulverized waste, which is disposed from the outer circumferential portion of the rotary blade attached to the lower side of the crushing rotor, and is disposed over the microbial digesting unit. Characterized in that the tube is open.

As a result, the crushed garbage dropped from the gap between the crushing rotor and the fixed blade is blown from the conveying tube to the microbial decomposing portion by the impact of the rotating blade rotating in conjunction with the crushing rotor, and the conveying tube is opened to the microbial decomposing portion. Therefore, even if the fluidity of the dry pulverized waste is bad, the conveying pipe is prevented from being blocked, and the pulverized waste is smoothly transferred.

In particular, the invention according to claim 14 is characterized by providing a suction type ventilation pump that sucks outside air into the microorganism decomposition unit and discharges the decomposition gas generated in the microorganism decomposition unit to the outside together with the outside air.

As a result, the outside air is circulated in the microbial decomposition unit by the suction-type ventilation system and is discharged to the outside. Thus, the decomposition gas generated in the microbial decomposition unit is discharged to the outside together with the outside air, and the microorganism decomposition unit is easily ventilated.

In particular, the invention according to claim 15 is characterized in that a microorganism carrier is provided with a heater for killing insects occurring in the microbial carrier but heating the microorganisms to a temperature at which the microorganisms are not killed.

As a result, the insects generated in the microorganism carrier are killed, while the microorganisms supported on the microorganism carrier are heated to a temperature at which the microorganisms are not killed. Therefore, the activity of the microorganisms is maintained and the occurrence of the insects in the microbial carrier is suppressed. Insects do not come out of the microbial decomposer when food waste is put in.

In particular, the invention according to claim 16 is characterized in that a check valve is provided in the connecting pipe connecting the microbial decomposing unit and the discharge pipe to prevent the backflow from the discharge pipe to the microbial decomposing unit.

As a result, the backflow into the microbial decomposition unit is prevented by the check valve for the wastewater and the decomposition gas discharged from the discharge pipe, thereby preventing the degradation of the decomposition performance in the microbial decomposition unit.

Particularly, in the invention of claim 17, the pulverization unit controls the pulverization rotor to alternately operate the electrostatic and reverse over a predetermined time, when a predetermined amount drops and accumulates in the upper portion of the crushing roller through the blocking member. It is characterized by having a means.

As a result, the wastes falling out accumulate on the upper part of the grinding rotor and accumulate, but when a predetermined amount is accumulated, the grinding rotor is reversed and reversed over a predetermined time by the control means. Since the waste is uniformly arranged on the top of the rotor, it is possible to prevent the obstacle of the rotation of the blocking member and at the same time to rotate the grinding rotor satisfactorily.

In particular, the invention according to claim 18 is characterized in that the control means stops the operation of the grinding rotor and generates an abnormal signal when the blocking member does not rotate to a predetermined position when the blocking member rotates.

As a result, when the blocking member does not rotate to a predetermined position at the time of rotation, the control means considers the abnormality and stops the operation of the grinding rotor, and at the same time generates an abnormal signal. It is possible to prevent the lack of drainage of the waste and the deterioration of the water quality of the wastewater and the degradation of the decomposition performance of the microorganisms, and to take prompt treatment for the rotational abnormality of the blocking member.

Particularly, in the invention of claim 19, the control means heats when the detected temperature of the heater temperature detector for detecting the surface temperature of the heater and the temperature detector for the carrier for detecting the temperature of the microbial carrier exceeds the upper limit of the respective set temperatures. When the flow to the air is cut off and the temperature is below the lower limit of the set temperature, the heater is energized and the stirring blade is operated during the power to the heater.

As a result, the microorganism carriers are intermittently controlled by the control means so that the microorganism carriers are stirred and fall within the respective set temperatures based on the detection temperatures of the heater temperature detector and the carrier temperature detector. Since it is heated uniformly in the inside, conditions favorable for the microbial decomposition action are maintained, and generation | occurrence | production of the worm in each part of a microbial carrier is suppressed.

Invasion to the inside can be prevented, and the same effect as the invention of claim 1 can be obtained.

In addition, according to the invention of claim 25, since the microbial carrier 111 lifted by the stirring blade 122 is scraped off by the carrier scraper 123, the decomposition inlet 119 to the microbial carrier 111 Can be prevented from being clogged, and the waste crushed by the grinding blade 378a can be reliably transferred to the inside of the microorganism decomposition unit 110 by a rotary blade 373d rotating in conjunction with the grinding rotor 378b. .

In order to achieve the third object, in the invention of Claims 26 to 32, a decomposition container 415 for accommodating a microbial carrier 431 carrying microorganisms for decomposing waste, and is provided in the decomposition container 416. The stirring blade 418 for stirring the waste and the microbial carrier 431 and the decomposition water 415 is installed at the bottom of the decomposition vessel 415, the decomposition water generated in the decomposition vessel 415 to the lower side of the decomposition vessel 415 It has a plurality of decomposed water drain holes 416d for discharging, while stirring the waste and the microbial carrier 431 with a stirring blade 418, the microbial carrier 431 near the decomposed water drain hole 416a ) To be scraped off.

In particular, the invention of claim 2 is characterized in that the shortest distance between the distal end of the stirring barrel 418 and the wastewater drain hole 416a is within 15 mm.

As a result, the stirring blade can effectively scrape off the microbial carrier near the upper portion of the decomposable drainage hole, and the clogging of the decomposed drainage hole by the microbial carrier can be greatly reduced.

In particular, in the invention of claim 28, the stirring bar 418 is configured to rotate the inside of the decomposition container 415 in the vertical direction by the rotation shaft 440 having the width direction disposed in the horizontal direction, and the name of the wastewater for decomposing water 416a. The opening surface of which is opened) is formed so that it may become a concentric circular arc surface with the rotation trace of the stirring blade 418, It is characterized by the above-mentioned.

Thereby, since the space | interval of the whole of the opening surface to which the decomposition water drainage name 416a opens, and the stirring member becomes constant, a microorganism carrier can be scraped off over the whole opening surface.

In particular, in the invention of claim 30, the stirring blade 418a at one end of the rotating shaft 440 is twisted so as to give the microorganism carrier 431 a force directed to the other end of the rotating shaft 440, and the rotating shaft 440. The stirring blade 418a at the other end of the blade is twisted so as to give the microbial carrier 431 a force directed toward one end of the rotation shaft 440.

As a result, the waste and the microorganism carrier have moved from one end to the other end in the axial direction of the rotating shaft, whereby the microorganism carrier and the waste in the microbial container can be stirred well.

In particular, in the invention according to claim 31, the stirring blades 418a and 418b are provided on each of both ends in a direction orthogonal to the axial direction of the rotating shaft.

As a result, when one of the stirring blades rotates, the microbial carriers and garbage are sent out while stirring the microbial carriers and garbage with the agitating blades. Is exported. Therefore, by repeating this operation, it is possible to effectively stir the microbial carrier and the garbage.

In order to achieve the fourth object, in the inventions of Claims 33 to 41, the microbial decomposition unit 515 for accommodating the decomposition products for decomposing waste, and the microorganism decomposition unit is installed in the sea of the microorganism decomposition unit 515 A plurality of decomposing water drain holes 516a for discharging the decomposed water generated in the 515 to the lower side of the microbial decomposing part 515 and a lower part of the decomposing water drain hole 516a, Decomposition water drainage passage 517 for discharging the decomposed water discharged from the 516a to the outside, a decomposing water drainage passage 517 for discharging the decomposed water discharged from the decomposed water drainage passage 517 to the outside; And a water channel 521 for inducing water for flowing down the foreign matter accumulated in 517.

As a result, water is guided to the decomposable drainage passage by the water channel, so that foreign matter deposited in the decomposable drainage passage by the water can flow down. As a result, the drainage of decomposed water can be improved.

In addition, the water mentioned here may be the wastewater which flowed out from the drain hole of a sink like the invention of Claim 34, and may flow the unused water from a tap water supply piping directly like the invention of Claim 35.

In particular, the invention of claim 34 has a sink 502 having a drainage hole 503 at the bottom and water work, and the water channel 521 communicates with the drainage hole 503. It is done.

Thereby, the wastewater which flowed out from the drain hole can be utilized effectively, and this substance accumulated in the wastewater drainage path can flow down.

Further, in the invention of claim 35, the upstream end of the water channel 521 is in communication with the water supply pipe 545.

As a result, by introducing water directly into the water channel from the water supply pipe, foreign matter attached to the decomposable drainage can flow down. In addition, at this time, it is possible to effectively flow down the foreign matter deposited in the decomposable drainage passage using the water pressure.

Moreover, especially in the invention of Claim 36, the water outlet part 521c of the water channel 521 is opened so that water may flow from the upstream to the downstream of the decomposable drainage path.

As a result, the foreign matter deposited in the decomposer can be effectively flowed down by using the flow of water from the water channel.

Further, in the invention of claim 37, the decomposable drainage passage 517 is inclined downward.

As a result, the water flows smoothly through the decomposable drainage channel, and the foreign matter deposited in the decomposed drainage channel can be effectively flowed down.

In particular, in the invention described in claim 38, there is an inlet 506 for injecting waste, an inlet 506 is provided below the drain hole 503, and the microorganism decomposing unit 515 is the sink 502. It is arrange | positioned in the neighborhood.

By the way, the stirring means improves the decomposition ability of the waste by stirring the decomposition product and the waste well.

However, when the agitation means is operated, the decomposition products are subdivided, resulting in a closed end from which the granular decomposition products leak out from the decomposable drainage hole, which in turn deteriorates the drainage of the decomposed water.

Therefore, according to the present invention, since the substance deposited in the decomposer for the decomposed water into the water flows down in conjunction with the operation stop of the stirring means, it is possible to discharge the decomposed water effectively.

In particular, in the invention of claim 40, the microorganism decomposition unit 515 has judging means 600 for judging whether or not the garbage has been transferred, and the stirring control means 600 is a judging means 600. If it is determined that the waste is transferred to 515, the stirring means 518 is operated for a predetermined time.

As a result, the waste water and the waste are agitated by the agitation means when the waste is transferred into the decomposition vessel, and therefore, it is possible to cause the substance which has been attached to the decomposition drainage path to flow down before the decomposition water is generated.

The water flowing out from the gap is discharged from the flow path provided around the pulverization tank 10. In the present embodiment, the gate storage chamber 16 is used as the flow path. The downstream side of the gate storage chamber 16 communicates with the upstream side of the trap portion 13a of the drain pipe 13.

30 is a conveying pipe which conveys the dry grinding | pulverization waste in the grinding tank 10 toward the microorganism decomposition part (henceforth a microorganism decomposition chamber) 40. As shown in FIG. The conveyance pipe 30 is a trumpet-shaped tube, and the cover 31 which is opened at the time of conveyance of the crushed garbage is attached to the discharge port of the conveyance pipe 30. The lid 31 is rotated by an electric motor, for example, and opens the discharge port of the conveying pipe 31 when the waste is being crushed in the pulverizing tank 10.

In the microbial decomposition chamber 40, a microbial carrier 41 carrying aerobic bacteria that withstands high temperature is opened and supported by a support plate 42 having water permeability. Condensed water (decomposed water) in the decomposition process occurring in the microorganism carrier 41 is discharged from the gap 43 to the discharge pipe 18.

44 is a stirring blade which is rotated by the stirring motor 45 to stir the microbial carrier 41. The microorganism decomposition chamber 40 is provided with a heater 60 described below for heating the microorganism carrier 41 to a predetermined temperature at a position not touching the stirring blade 44.

An intake port 51 having a filter 52 made of an active plate or the like is provided above the microbial decomposition chamber 40, and outside air from the intake port 51 by the ventilation pump 50 is passed through the filter 52. It is intended to be sucked into the decomposition chamber 40.

Decomposition gas generated in the microbial decomposition chamber sucked from the suction port 51 is exhaust pipe 55 through the suction pipe 153, the ventilation pump 50 and the discharge pipe 54, as indicated by the arrow A in the first diagram. ), And into the discharge pipe 13 downstream of the trap part 13a.

Moreover, the clearance 43 located below the microbial decomposition chamber 40 is connected to the discharge pipe 18 by the communication pipe 56, and the communication pipe 56 is connected to the microbial decomposition chamber 40 from the discharge pipe 18. The check valve 57 which prevents reverse flow is provided.

The heater 60 installed in the microorganism decomposition chamber 40 is composed of a double tube type pipe heater in which a rod-shaped siege type or rod-shaped ceramic heat transfer heater 61 is housed in a cylindrical outer cylinder 62. have. The heater 60 is provided with a heater temperature sensor 63 for detecting the surface temperature of the outer cylinder 62 and a temperature fuse 64 that melts and cuts when the surface temperature of the outer cylinder 62 is equal to or higher than the set temperature. .

FIG. 2 is a perspective view of the crushing unit 20, and FIG. 3 is a longitudinal sectional view of the crushing unit 20. As shown in FIG. In FIG. 2 and FIG. 3, 21 is a grinding motor and 22 is a cylindrical casing. The cylindrical fixed blade 23 is provided in the inner peripheral part of the casing 22.

In the upper portion of the fixed blade 23 of the casing 22, an aperture portion 22a is formed to push the crushed waste downward.

24 is a disc-shaped crushing rotor provided with a hammer 24a for crushing garbage by a striking force, and is disposed with a predetermined gap between the cylindrical fixed blade 23. Then, the waste pulverized by the hammer 24a is pulverized by the transmission force of the fixed blade 23 in the process of passing through the gap.

A rotary blade (hereinafter referred to as an impeller) 25 is attached to the lower side of the grinding rotor 24. The impeller 25 is dropped from the gap between the fixed blade 23 and the grinding rotor 24, which is to rotate in communication with the grinding rotor 24, and the waste that is pulverized is conveyed later by the impact force of the impeller 25 ( 30 is blown into the microbial decomposition chamber 40 is conveyed.

The casing 25 which faces the outer peripheral part of the impeller 25 is provided with the conveyance pipe 30 which spread | opened the trumpet shape toward the microorganism decomposition chamber 40. As shown in FIG. In addition, the inner wall of the fixed blade 23 is provided at approximately equal intervals inclined at a predetermined angle so as to push down the pulverized waste down the plurality of projection guide plates 26.

Next, the operation of the present embodiment will be described. In the state where power is supplied to the food waste processing apparatus (the outlet is flowered), the ventilation pump 150 is always in operation, and as indicated by the arrow A in the first way, the filter (see FIG. 52, the outside air is sucked into the suction pipe 53, and once sucked into the suction pipe 53, the discharge pipe 54 passes through the outside of the microbial decomposition chamber 40 and is exhausted into the drain pipe 13 through the exhaust pipe 55, so that microbial decomposition is performed. The chamber 40 is always ventilated.

In addition, in the state where power is supplied to the food waste treatment apparatus, the agitator control described later is performed by the control apparatus 100 described later, and the heater 60 is energized by being supplied to the heat transfer heater 61, so that the microorganism carrier The 41 is heated, and the microorganism carrier 41 is maintained at the required insecticidal temperature, for example, 40 ° C. to 60 ° C. by the control device 100 based on the detected temperatures of the temperature sensors 63 and 65.

In this state, when the shield cover 5 of the sink 1 is opened and food waste containing moisture from the inlet 11 is inserted into the pulverizing tank 10, the spherical upper surface of the drain gate 14 Garbage accumulates, but moisture in the accumulated waste flows in the circumferential direction along the water drain gate 14 formed naturally in a spherical shape.

This water is drained to the drain pipe 13 through most of the water in the waste through the small hole of the drain portion (12). The remaining water flows along the upper surface of the drain gate 14 and flows into the gate compartment 16 from the gap with the upper leaf seal 17d and is drained to the drain pipe 13 at the bottom of the gate containment 16. .

Therefore, since the water in the waste accumulated in the drain gate 14 is sufficiently drained and drained into the drain pipe 13, the pulverized fine waste is not mixed in the drainage, and the water quality of the drainage is maintained well. In addition, unless the lid 11 is closed with the shield lid 5 and the reed switch is turned ON, and the operation switch described later is turned ON, the drain gate 14 is closed and the grinding rotor 24 is not to rotate. As a result, the draining gate 14 is in a closed state between the draining portion 12 and the grinding rotor 24 while the waste is drained in the closed state. Therefore, it is possible to prevent the water taken out of the garbage from flowing into the pulverization tank 10. As a result, as will be described later, when the waste is pulverized in the pulverization tank 10, the waste can be prevented from being in a state containing much moisture.

Then, when it is determined that the waste drained on the upper side of the drain gate 14 has been accumulated by the user, and the inlet 11 is closed with the lid 5, the operation switch described later is turned ON. The controller 100 rotates the rotary motor 15 to rotate the water draining gate 14 until it is stored in the gate compartment 16.

Since the waste accumulated on the upper surface of the drain gate 14 during the rotation of the drain gate 14 is scraped off by the upper leaf seal 17d, it rarely penetrates into the gate compartment 16. In accordance with the rotation of the water draining gate 14, the trash drained to the lower crushing unit 20 falls.

After the predetermined time, the drain gate 14 stored in the gate compartment 16 is rotated to block the inlet 11 by the rotation motor 15, and the garbage dropped to the pulverization unit 20 is The shaking control described later is performed in the crushing unit 20.

As shown in FIG. 3, the garbage falling into the pulverization tank 10 is crushed by the striking force of the rotating hammer 24a, and the gap between the fixed blade 23 and the pulverization rotor 24 is notified. At the time of grinding, fine grinding is performed by the shear force of the fixed blade 23. Then, the grinding plate 24 of the grinding rotor 24 is formed by the guide plate 26 inclined at a predetermined angle on the inner wall of the fixed blade 23 and the aperture 22a of the casing 22 formed on the upper portion of the fixed blade 23. The crushed waste accumulated on the upper side is pushed down from the gap and falls, and is blown into the microbial decomposition chamber 40 through the conveying pipe 30 by the rotating impeller 25 and transported.

In FIG. 1, the drained waste transported to the microbial decomposition chamber 40 is decomposed by the microorganisms in the microbial carrier 41 to be decomposition gases (CO ₂ and H ₂ O). The decomposition gas is discharged to the drain pipe 13 together with the outside air indicated by the arrow A, which distributes the space in the microbial decomposition chamber 40 by the ventilation pump 50. The decomposition gas is discharged together with the drainage indicated by the arrow B drained from the drain pipe 13 and the condensed water indicated by the arrow C in the microbial carrier 41 drained from the gap 43 through the communication tube 56. It is discharged | emitted to sewage etc. as indicated by arrow D from (18).

As a result, the ventilation in the microorganism decomposition chamber 40 can be performed smoothly.

Here, since the microbial carrier 41 is heated to 40 ° C. to 60 ° C. by the heater 60, the occurrence of insects in the microbial carrier 41 is suppressed, and the shield cover 5 at the time of garbage injection is prevented. When opening, insects do not emerge from the microbial decomposition chamber 40 to the part of the sink 1.

In addition, drainage from the discharge pipe 18 to the microbial decomposition chamber 40 is provided by a check valve 57 provided in the connecting pipe 56 connecting the lower gap 43 of the microbial decomposition chamber 40 and the discharge pipe 18. Since the reverse flow of the decomposition gas is prevented, the degradation of the decomposition performance of the microorganisms in the microorganism decomposition chamber 40 can be prevented. In addition, the decomposition gas discharged to the drain pipe 13 through the exhaust pipe 55 is prevented from flowing back to the pulverization tank 10 through the drain pipe 13 by the trap part 13a provided in the drain pipe 13.

Next, as shown in FIG. 4, the inclination angle [theta] of the guide plate 26 provided on the inner wall of the fixed blade 23 and the number of the guide plates 26 are standard wastes (in weight ratio of vegetables 60). %, Grain 20%, fruit 10%, meat 10%) the results of testing the performance is shown in FIG. However, the treatment performance was defined by the definition of number 1.

As apparent from FIG. 5, it was confirmed that the inclination angle θ of the guide plate 26 had the highest processing performance near 45 °, and the highest processing performance was obtained when the number of the guide plates 26 was eight. .

Next, as shown in FIG. 6, the processing time of standard waste and udon (noodles) in the case of the diaphragm installation height of 0 mm mentioned later with respect to the aperture angle (theta) of the aperture part 22a of the casing 22 is mentioned later. The test results are shown in FIG. Moreover, as shown in FIG. 6, with respect to the diaphragm mounting height H from the fixed blade 23 to the diaphragm 22a, when the diaphragm angle is 30 degrees, the processing time of standard waste is tested. 8 is shown.

As is apparent from FIG. 7, the treatment time of the aperture 22a is about 30 °, and the processing time is shortest. In the case of viscous bodies such as udon noodles, the treatment time is not applied. It was confirmed that it takes a long time. Moreover, as apparent from FIG. 8, it was confirmed that the processing time was shortened, so that the squid installation height H was small.

Next, FIG. 9 shows the scattering angle of the dry crushed garbage by the impeller 25, where θ ₁ in FIG. 9 (a) is the vertical scattering angle and θ ₂ in FIG. 9 (b) is the horizontal scattering. The angle is shown. However, in the experiment, the rotation index of the impeller 25 was 1750 revolutions per minute, and the blade angle with respect to the center direction of the impeller 25 was 45 °.

As shown in FIG. 9 (a), the scattering angle θ ₁ of the pulverized waste in the longitudinal direction is 17.0 ° above the upper end of the discharge hole 27 of the crushed waste provided in the casing 22, and It was confirmed to fly at an angle of 30.7 ° below the bottom. On the other hand, as shown in FIG. 9 (b), the scattering angle θ ₂ of the crushed waste in the horizontal direction is 43.10 on the left side of the drawing than the tangential direction of the tip of the discharge port 27 with respect to the rotational direction of the crushing rotor 24. It was confirmed that the line was scattered at an angle formed by a line 24.5 ° to the left of the drawing rather than the tangential direction of the lower end of the discharge port 27.

As described above, even if the fluidity of the pulverized waste is not hindered by making the conveying pipe 30 have a shape in which the tube is opened toward the microbial decomposition chamber 40, the scattering of the crushed waste is not impeded. Crushed waste is blocked, and conveyance of crushed waste to the microorganism decomposition chamber 40 is not inhibited. Therefore, the pulverized waste can be smoothly conveyed to the microbial decomposition chamber 40. Particularly, if the conveyance pipe 30 is an angle at which the tube opening in a trumpet shape toward the microbial decomposition chamber 40 becomes an angle of θ ₁ or more in the longitudinal direction and θ ₂ or more in the transverse direction, preventing the scattering of the crushed waste Therefore, the pulverized waste is blocked in the broadcasting tube 30, so that the conveyance of the crushed waste to the microorganism decomposition chamber 40 is not hindered.

Next, the main control by the said control apparatus 100 in this embodiment is demonstrated in detail.

[Pulverization ventilation control]

First, the pulverizing ventilation control will be described based on FIGS. 10 to 13. In FIG. 10, when the power switch 108 derived from the power source 107 (in this case, the outlet installed in the food waste processing apparatus is plugged into the power source) is inputted, the control device 100 controls the eleventh step. Control in accordance with the flowchart shown in FIG. Is performed.

When the power switch 108 is turned on, the relay 101 shown in FIG. 10 is energized, the contact 101a is closed, and the ventilation pump 50 is operated to ventilate the microorganism decomposition chamber 40 (step). S1).

Subsequently, it is judged whether or not the reed switch 6 is turned on (step S2), and when it is turned on, that is, when the shielding lid 5 is closed in the inlet 11, the pulverization control described later. Becomes possible.

Next, for example, it is determined whether or not the operation switch installed in the food waste processing apparatus is turned on (step S3). And this operation switch is an operation switch operated by a user. That is, pulverization control is performed only when the shield cover 5 blocks the inlet 11 and the operation switch is turned ON.

When the operation switch is turned ON, the relay 102 is energized to close the contact 102a and the rotary motor 15 rotates in the direction of opening the water draining gate 14 (step S4). Further, for example, by using a potentiometer, which is a rotation position detecting means for detecting the rotation position of the rotation motor 15, the water drain gate 14 determines whether the rotation motor 15 is in the open position (step S5). And the shaking control is performed in the open position (step S6), and when the shaking control ends, the rotary motor 15 rotates in the direction of closing the drain gate 14 (step S7).

Subsequently, it is judged whether or not the rotary motor 15 is in the closed position (step S8). If the rotary motor 15 is in the closed position, the relay 103 is energized so that the switching contact 103a enters a side of the forward rotation and the grinding rotor 24 The grinding motor 21 which rotates and rotates is rotated (step S9).

Then, while the grinding motor 21 is rotating, it is judged whether or not the reed switch 6 is turned on (step S10). When the grinding motor 21 is turned on, the grinding motor 21 is rotated by two. It is judged whether or not elapsed for a minute (step S11). That is, when the reed switch 6 is turned ON and the shielding lid 5 is not closing the inlet 11, the grinding motor 21 does not rotate. In addition, when the shielding cover 5 opens the inlet port 11 for two minutes while the grinding motor 21 is rotating, energization to the relay 103 is interrupted, and the switching contact 103a is opened, and the grinding motor 21 is opened. ) Stops (step S12).

In addition, when the rotation motor 15 is not in the open position in step S5 and when the rotation motor 15 is not in the closed position in step S8, it is regarded as abnormal in the rotation of the water draining gate 14. The control is made (step S13), the LED 106 is blinked to inform the user that there is an error (step S14), and the grinding motor 21 is stopped at step S12.

Next, the control to shake in step 6 mentioned above is demonstrated.

12 shows a flow chart of this shaking control.

First, the rotary motor 15 judges again whether or not the drain gate 14 is in the open position to open the inlet 11 (step S21), and energizes the relay 103 if it is in the open position (step S21). Step S22), the switching contact 103a enters the a side of the forward rotation, and the grinding motor 21 rotates forward (step S23), and then the switching contact 130a enters the b side of the reverse rotation, and the grinding motor 21 Rotates in reverse (step S24), and the above-described forward and reverse rotation is repeated.

If the forward and reverse rotation speed n has been determined N times (step S25), and if it has been performed N times, energization to the relay 103 is cut off (step S26) and the switching contact 103a is opened to pulverize. The motor 21 stops.

In step S25, when the normal and reverse rotation speed n is not carried out N times, forward and reverse rotation is performed n + 1 times (step S27), and it returns to step S23 and repeats. In addition, since the forward and reverse rotations of the grinding motor 21 are performed at a cycle of, for example, 0.5 seconds, and the forward and reverse rotation speed N is performed, for example, ten times, the grinding rotor 21 is interlocked with the forward and reverse rotation of the grinding motor 21. Since the 24 rotates forward and backward, the drained waste dropped and accumulated on the upper part of the grinding rotor 24 is shaken to be flat, so that the drained garbage accumulated on the upper part of the grinding rotor 24 is drained. Obstacles of rotation) are prevented.

FIG. 13 shows the relationship between the operating angle of the rotary motor 15 of the drain gate 14 by the potentiometer and the detection voltage. When the rotation motor 15 is normal, the detection voltage is equal to or greater than E1 volts (determined to be opened above E1 volts) at the operating angle of the rotation motor 15, and less than or equal to the detection voltage E2 volts at the closed position. (Determined to be closed below E2 volts), and when the detected voltage is below E1 volts in the open position and above E2 volts in the closed position, the drain gate 14 is considered to be not rotating to a predetermined position. Control is performed. This is the case, for example, when garbage is gathered.

As a result, the operation of the grinding motor 21 stops, the operation of the grinding motor 24 stops, and the LED 106 blinks to generate an abnormal signal. As a result of the lack of drainage of the waste caused by the wastewater, and thus the conveyance of the kitchen drainage directly to the microbial decomposition chamber 40 is stopped, the water quality of the wastewater and the degradation of the decomposition performance by the microorganisms are prevented and the drainage gate 14 is prevented. You can quickly take action against an abnormal turn.

[Temperature stirring control]

Next, the hot-stirring control will be described based on FIG. 10, FIG. 14 and FIG. 15. FIG.

As shown in FIG. 14, in the heat insulation chamber 40a constituting the casing of the microbial decomposition chamber 40, the temperature element 63a is applied to the surface of the left barrel 62 of the heater 60 via the holder 66. Is mounted to a heater temperature sensor 63 with a built-in heater and a temperature fuse 64 with a built-in fuse element 64a. On the other hand, the temperature sensor 65 for a carrier is attached to the other place of the heat insulation wall 40a.

The temperature element 63a and the fuse element can be detected so that the surface temperature of the outer cylinder 62 can be detected in accordance with the effective heat generating portion S of the rod-shaped heat transfer heater (hereinafter referred to as a heater) 61 provided in the outer cylinder 62. The position of 64a is set.

Next, in FIG. 10, when the power supply slot 108 is turned on, the control apparatus 100 performs control according to the flowchart shown in FIG.

First, it is determined whether or not the carrier temperature sensor 65 is in an ON condition (step S31). Here, the ON condition means determining whether the temperature of the microorganism carrier 41 is lower than a predetermined set temperature (for example, 50 ° C).

When it is determined in step S31 that the temperature of the microorganism carrier 41 is lower than 50 ° C, it is again determined whether the heater temperature sensor 63 is in the ON condition (step S32). Here, the ON condition in this stem S32 means determining whether the temperature of the effective heat generating unit S detected by the heater temperature sensor 63 is lower than a predetermined set temperature (for example, 70 ° C.). . The set temperature of 70 ° C. is a temperature at which the entire microbial carrier 41 can be heated as soon as possible without killing the microbial carrier 41 at a position close to the heater 61 as much as possible.

When it is determined in step S31 and 32 that the temperature is lower than the set temperature, the relay 105 is energized, the contact 105 is closed, the heater 61 is energized (step S33), and the heater 61 generates heat to support the microorganism carrier. Heat (41).

At the same time, the relay 104 is energized, the contact 104a is closed, the stirring motor 45 is rotated (step S34), the stirring blade 44 is driven to rotate, and the microorganism carrier 41 is stirred.

If it is determined in step S31 that the temperature of the microorganism carrier 41 is higher than 50 degrees or the temperature of the effective heat generating unit S is higher than 70 ° C in step S32, no energization is applied to the relay 105 and the contact 105a is applied. Is open, the heater 61 is not energized (step S35) and at the same time the relay 104 is not energized, the contact 104a is opened, and the stirring motor 45 is stopped (step S36).

The control apparatus 100 determines whether or not the pulverizing motor 21 is operating regardless of the ON / OFF state of the operation switch by the input of the power switch 108 (step S41). That is, in this embodiment, unless the operation switch is turned ON, the grinding motor 21 and the stirring motor 45 are controlled to stop.

Therefore, it may be said that the state of the grinding motor 21 is determined in step S41, and the state of the stirring motor 45 may be determined.

However, if the operation switch is not turned ON by the user and the waste treatment is not performed for a long time, the oxygen supply to the entire microbial carrier 41 becomes insufficient, and the decomposition performance of the garbage by the microbial carrier 41 is deteriorated. have.

Therefore, in step S42, it is judged whether the stop of the stirring motor 45 has resulted for more than a predetermined time (24 hours in the present embodiment), and when the predetermined time has elapsed, it is energized by the relay 104 and contacts ( 104a) is closed, the stirring motor 45 is operated, and oxygen is dispersed and supplied to the whole microorganism carrier 41 (step S43).

If it is determined in step S41 that the grinding motor 21 is ON, the process proceeds to step S43. However, the grinding motor 21 is operated in step 11 when the grinding motor 21 is operated. ) Means ON, and in this embodiment, the grinding motor 21 is operated for 2 minutes to be ON. At the same time as the grinding motor 21 is turned on in step S43, the stirring motor 45 is also turned on to operate for 3 minutes.

Therefore, if the grinding motor 21 is in operation, the stirring motor 45 is also normally operated, whereby it is determined as YES in step S41, the flow proceeds to step S43 and step S44, and the stirring motion in step S44. When the rotor 45 is operated for three minutes, the flow advances to step S36 to stop the stirring motor 45.

As described above, the microbial carrier 41 is stirred by the stirring blade 44 which is rotationally driven by the stirring motor 45, and at the detected temperature of the temperature sensor 63 for the heater and the temperature sensor 65 for the carrier. Since the energization to the heater 61 is intermittently controlled so as to fall within the range of the set temperature, the condition of the oxygen rich at an appropriate temperature at which the microorganism carrier 41 is uniformly heated within the range of the set temperature to promote the decomposition operation of the microorganisms. At the same time, the occurrence of insects in each part of the microbial carrier 41 is also suppressed.

Then, when the above-described temperature control occurs and the heater 61 is abnormally heated, the temperature fuse 64 attached to the surface of the outer cylinder 62 melts and is cut off, thereby interrupting the energization to the relay 05. Since the contact 105a is opened and the energization to the heater 61 is cut off, the heat of the combustible microorganism carrier 41 is prevented and the stability of the apparatus is ensured.

Next, 2nd Embodiment is described using FIGS. 16-24.

Incidentally, the same functions as those in the first embodiment are denoted by the same reference numerals, and only the portions different from the food waste processing apparatus in the present embodiment and the food waste processing apparatus in the first embodiment will be described next. do.

The control cable 85 is arranged to extend upward from the pedal 82, and the other end of the control cable 85 is connected to the rotary shaft 86 of the drain gate 14 through a lever piece or the like described later. Connected.

In addition, 87 in FIG. 17 is a decomposition container for forming the microbial decomposition chamber 40, and is able to be taken out immediately in front of the ground in FIG. It is.

On the right side of the drawing of the driven lever piece 90, the switch element part 91 which interlocks with the driven lever piece 90 to open and close the water draining gate 14 and generates an ON / OFF signal for operating the waste disposal apparatus. ) Is installed.

As shown in FIG. 19, the switch element portion 91 is fixed to the outer wall surface of the case 89, and the switch element portion 91 is provided with a switch portion 92 and a wiring portion 93. When the switch unit 92 performs a predetermined switch operation, a drive signal for driving the grinding motor is output to the control device 81.

The metal leaf spring 94 is attached to the switch element 91, and the switch 92 is turned on and off by the leaf spring 94. As shown in FIG.

On the left side of the drawing of the driven lever piece 90, a guide groove 96 engaging with the drive lever piece 95 described later is formed. And as shown in FIG. 18, this guide groove 96 is formed in the shape bent in an L shape, and is guided by the guide part 96a and the idle part 96b on the basis of this L-shaped angle. Consists of.

In the guide groove 96, as shown in FIG. 18, a pin shaft portion 97 provided on the drive lever piece 95 is inserted. One end of the control cable 85 is attached to the drive lever piece 95. Moreover, one end of the spring 98 which is a vine-shaped spring member is connected to the opposite side to the site | part in which the shaft part 97 of the drive lever piece 95 was formed. The other end of the spring 98 is supported by the support 99 formed integrally with the case 89.

And this spring 98 is for returning the water draining gate 14 to an initial position naturally when no operation force is applied to the pedal 82. In addition, the initial position here is a position where the water draining gate 14 cuts off between the inlet 11 and the grinding | pulverization part 20 (refer FIG. 16).

As shown in FIG. 18, the cone cable 85 consists of the metal wire part 85a and the cylindrical pipe part 85b formed so as to cover this wire part 85a, and this pipe part ( The operation of the wire part 85a is supported by the pipe support part 110 integrally formed in the case 89 with 85b).

Next, the operation of the operation mechanism 83 will be described based on FIGS. 20 to 21. 20 to 21 are exploded views showing the operation relationship between the water drain gate 14, the pedal pedal 82, the control cable 85, the driven lever piece 90 and the drive lever piece 95.

As shown in FIG. 20 (a), when the operating force is not transmitted to the pedal 82, the pedal 82 is separated from the bottom 111 of the kitchen unit by about 35 mm (the height indicated by h in the figure). . In this state, the driven lever piece 90 and the drive lever piece 95 are in the operating positions as shown in FIG. 20 (b) by the pressing force of the spring 98.

As shown in FIG. 20 (c), the drain gate 14 becomes an operating position (initial position) that completely blocks the raw rubber inlet of the pulverization tank 10. That is, it becomes an operation position which cuts off between the inlet 11 and the grinding | pulverization part 20 (refer FIG. 16).

Next, in the state shown in FIGS. 20 (a) to 20 (c), as shown in FIG. 21 (a), as the pedal 82 stepped by the user steps downward in the figure. The control cable 85 is pulled to the left in the figure. As a result, as shown in FIG. 21B, the control cable 85 is pulled downward in the drawing to rotate the drive lever piece 95 in the direction of the arrow.

As a result, as shown in FIG. 20 (c), the drive lever piece 95 is interlocked, and the water draining gate 14 becomes an operating position in which the water draining part 12 and the grinding part 20 communicate with each other. .

At this time, in order to pull the control cable 85 downward in FIG. 21B through the pedal 82, it rotates against the pressing force of the spring provided on the driven lever piece 90. As shown in FIG. In addition, when the water draining gate 14 is rotated any further, it is indirect to the pulverization tank 10, so that it cannot be rotated again in the same direction in the state shown in Fig. 21C.

As a result, the user may transfer the waste to the grinding unit 40 through the inlet 11 while the draining gate 14 communicates the draining unit 12 and the grinding unit 20.

Then, in the state of FIG. 21 (a), as shown in FIG. 22 (a), the pedal 82 can be stepped further downward, and the amount of stepping is provided on the attachment part rack 84. It is until the pedal 82 which steps on the stopper part 112 abuts.

When the pedal 82 is stepped downward in this manner, as shown in FIG. 22 (b), the drive lever piece 95 further rotates in the direction of the arrow in the drawing via the control cable 85. And as shown in FIG. 22 (b), the shaft portion 97 of the drive lever piece 95 is rotated by the idle part 96b of the driven lever piece 90, The driven lever piece 90 hardly rotates.

That is, as shown in Figs. 21A to 21C, the pedal 82 which presses again again in the state where the water draining gate 14 completely opens the garbage intake opening of the pulverization tank 10 is shown. ), The amount of rotation of the driven lever piece 90 is smaller than the amount of rotation of the drive lever piece 95 by the idling portion 86b. And in this embodiment, when the shaft part 97 of the drive lever piece 95 moves along the idle part 96b, the rotation amount of the driven lever piece 90 becomes almost zero.

The reason for this is that since the pedal 82 is mainly stepped on by the user's foot, a considerable operating force is applied to the drive lever piece 85 and the driven lever piece 90 via the control cable 85.

When the pedal 82 is stepped rapidly without forming the idler 96b, the step is instantaneously operated to the state shown in Figs. 20 to 22, but the driven lever piece 90 and the driving lever piece 95 ), The operation force (impact force) is applied, and the driven lever piece 90 and the drive lever piece 95 may be damaged.

Therefore, as described above, by providing the idling portion 96b on the driven lever piece 90, the impact force can be alleviated, and the damage of the driven lever piece 90 and the drive lever piece 95 can be prevented.

Next, the operation and operation of the waste disposal apparatus in this embodiment are explained based on FIG. 16 and FIG.

As shown in FIG. 18, one end (right side in the drawing) of the driven lever piece 90 is in a state in which the drain gate 14 inlet 11 (not shown in FIG. 18) is completely closed. The switch portion 92 is pressed (ON) through the leaf spring portion 94.

When the pedal 82 is stepped down in this state, the driven lever piece 90 is separated from the leaf spring portion 94, so that the switch portion 92 is turned off. When the pedal 82 is stepped on again, the water drain gate 14 stops stepping on the pedal 82 in a state where the inlet 11 and the crushing unit 40 communicate with each other (the foot is released from the pedal 82). The driven lever piece 90 is returned to the initial position (the position shown in FIG. 18) by the spring 98, so that the drive lever piece 95, the control cable 85 and the stepping pedal 82 are ) Will also return to the initial position.

In addition, when the pedal 82 which steps on here returns to an initial position, as shown in FIG. 18, the switch part 92 turns ON. Then, the control device 81 considers that the drainage gate 14 is in a closed state in the opened state, and determines that the waste is transferred to the crushing unit 20 by the user.

That is, the control apparatus 81 in this embodiment is turned OFF by operating the pedal 82 which presses the switch part 92 in the ON state, and this OFF state is more than predetermined time (for example, 1 second). Subsequently, when the pedal 82 is stepped back to the initial position and is turned ON, the grinding rotor 24 of the grinding unit 20 is rotated only for a predetermined time (2 minutes in this embodiment).

Then, the waste water is pulverized, the waste pulverized by the impeller 25 is transferred to the microbial decomposition chamber 40 through the conveying pipe (30).

That is, the operation of the waste disposal apparatus according to the present embodiment is operated only by the pedal pedal 82 after the power is turned on, so that, for example, even if there is no waste in the crushing unit 20, when the pedal 92 is stepped on, the crushing rotor 24 is operated. It is supposed to rotate. In addition, in the above 2 minutes, the grinding rotor 24 is stopped, the grinding processing is stopped, and the control device 81 is controlled so that the grinding rotor 24 stops when the pedal is pressed again during loading.

Again, details of the control of the grinding rotor 24 will be described based on FIG. 23 and FIG. 23 is a circuit diagram of the grinding rotor 24, and FIG. 24 is a flow chart showing the control contents of the grinding rotor 24. As shown in FIG.

The grinding motor 24 shown in FIG. 23 is comprised, for example with a single phase induction motor, and is equipped with the capacitor | condenser 170 for starting (for driving). In addition, the circuit is provided with a power switch 155 and a switching switch (hereinafter referred to as a switching relay) 103a. The switching relay 103a has a contact point on the forward rotation side and a contact on the reverse rotation side. (b) is selectively switched.

A half-wave rectifying diode 151 is provided between the contact b on the reverse rotation side and the grinding motor 24. In this circuit, a bypass circuit 154 composed of a resistor 152 and a capacitor 153 is provided in parallel with the power switch 108.

And, as shown in FIG. 25, as for the control content of the grinding | pulverization motor 24, whether the power supply switch (capacitor is plugged in) is input, and the switch part 92 (indicated by SW in drawing) is turned ON. (Whether the gap between the inlet 11 and the crushing unit 20 is blocked by the drain gate 14) is determined (step S156), and if the switch unit 92 is ON, the process goes to step S157. Proceed.

In step S157, as described above, the pedal 82 which is pressed in the ON state of the switch unit 92 is turned OFF, and this OFF state continues for a predetermined time (for example, 1 second) or more, and then the pedal is pressed. It is determined whether or not 82 is returned to the initial position and turned ON.

And if it determines with YES in step S157, it considers that the waste was conveyed to the grinding | pulverization part 20, and progresses to step S158 to rotate the main rotor 24. As shown in FIG.

In step S158, the changeover relay 10a is set as the contact a on the forward rotation side, and the power switch 155 is turned ON to rotate the grinding motor 24. Then, when the grinding motor 24 is rotating in step S159, the pedal 82 is pressed again to determine whether the switch section 92 is turned from ON to OFF.

That is, in step S159, the pedal 82 is operated again while the grinding motor 24 is rotated to determine whether the draining gate 14 has communicated with the inlet 11 and the grinding unit 20 and communicated with each other. If it is determined, the flow advances to step S160 to perform stop control. If it is determined that no communication is made, the flow advances to step S161, and the grinding motor 24 rotates for only 2 minutes as described above.

By the way, when the pedal 82 is stepped while the grinding motor 24 rotates so that the drain gate 14 communicates between the inlet 11 and the grinding unit 20, the grinding motor 24 ) Needs to be stopped. The reason for this is that a malfunction of the grinding motor 24 due to entry of foreign matter from the inlet 1 or the waste in the crushing unit 20 scatters to the inlet 11.

For example, when the power switch 155 is turned OFF to stop the grinding motor 24, the motor is stopped. However, there is still a problem because it cannot be stopped immediately by the inertia force of the grinding motor 24.

So, in this embodiment, stop control as shown in step S160 is performed. In step S160, first, the power switch 155 is turned OFF, and then after a T1 time (20 ms in the present embodiment), the switching relay 103a is switched from the contact a on the forward rotation side to the contact b on the reverse rotation side. .

Then, after switching the power relay 103a from the contact a to the contact b, the pulverizing motor 24 is turned on again by turning the power switch 155 ON after T2 time (25 ms in this embodiment). Although current flows so as to reverse rotation, it is difficult to suddenly stop the crushing motor 24 only by switching from the contact point a to the contact point b, and the reverse rotation occurs again.

Therefore, in this embodiment, the AC voltage is half-wave rectified by the half-wave rectifying diode 151, so that the switching relay 103a is switched from the contact a on the forward rotation side to the contact b on the reverse rotation, and then crushed. It is possible to stop the grinding motor 24 quickly within a short time without the motor 24 being reversed.

In addition, supplying a stop power supply to the crushing motor as claimed in claim 10 means that the AC voltage obtained by switching the switching relay 103a from the contact point a to the contact point b and rectifying half-wave rectified is applied to the crushing motor 24. to be.

After the stop voltage is given only to the T3 time (300 ms in the present embodiment), the switching relay 103a is returned to the contact a after the T4 time (20 ms in the present embodiment).

As described above, when the grinding motor 24 is stopped, first, the power switch 155 is turned OFF, and then the switching relay 103a is rotated from the forward rotation side a to the reverse rotation side b. ) Is for the following reasons.

That is, after the power switch 155 is turned ON (it is ON in the present embodiment) and the switching relay 103a is switched, an overcurrent occurs when the switching relay 103a is brought into contact with the contact b on the reverse rotation side. Flows and the durability and reliability of the contact b (or the contact a) are reduced.

Therefore, in this embodiment, since the power switch 155 is turned ON after switching the switching relay 103a first, the durability and reliability of the contact point b can be improved.

The time of T1 to T4 described above is determined in consideration of the durability and reliability of the switching relay 103a and then taking into account the driving time (delay time) of the switching relay 103a.

As described above, when the pulverizing motor 24 is supplied with a stationary power supply, an overcurrent flows through the switching relay 103a to degrade the durability and reliability of the switching relay 103a. However, in the present embodiment, the switching relay ( Since the bypass circuit 152 composed of the resistor 152 and the capacitor 153 is provided in parallel with the 103a, overcurrent can be prevented from flowing to the switching relay 103a.

In the present embodiment, as described in step S161, even after the grinding motor 24 is operated for two minutes, the flow advances to step S160 to perform the stop control described above.

As described above, the waste disposal apparatus in the present embodiment is configured to operate and stop the waste disposal apparatus only by operating the pedal 82 after the power is turned on, so that the user can easily use the waste disposal apparatus.

In addition, although the water drain gate 14 was rotated by the electric motor 15 in the said 1st Embodiment, there exists a possibility that a user may put a hand, for example. In addition, when the rotary motor 15 breaks down and locks, it is difficult for a user to check or work in the waste disposal apparatus (particularly, the crushing unit 20). However, in this embodiment, since the drain gate 14 rotates arbitrarily according to a user's operation force (tread), the pulverization part 20 can be easily checked by removing the drain part 12. FIG.

In addition, since the pulverization rotor 24 is rotated after the drain gate 14 naturally closes the inlet port 11 by the spring 98, the pulverization motor 24 is operated by the user by hand. Can be prevented.

In addition, by installing the foot pedal 82 below the kitchen cabinet 80, in many cases, the foot pedal 82 is operated by the foot of a user. Therefore, both hands of the user are left in an empty state, and after the pedal is opened and the water draining gate 14 is opened, the garbage can be transferred to the crushing unit 20 or other operations can be easily performed.

Next, a third embodiment of the present invention will be described. In addition, this embodiment differs in the structure of the water draining part 12 and the water draining gate 14 compared with the said 1st, 2nd embodiment. In addition, the same code | symbol is attached | subjected to the thing of the same function as the said embodiment.

Fig. 25 shows a schematic perspective view in which the water draining portion 12 and the water draining gate 14 are attached to the garbage disposal apparatus. FIG. 26 shows a single view of the water draining portion 12 removed by the water draining gate 14 from the garbage disposal apparatus.

As shown in Figs. 25 and 26, the water draining portion 12 in the present embodiment is formed of a metal having excellent corrosion resistance, such as stainless steel, for example, in a quadrangular tubular shape. A drain hole is formed.

In addition, when the drain gate 14 closes the inlet port 11 to the drain part 12 on the left side in the left and right direction in FIG. 25, the inlet port 11 is along the surface of the drain gate 14. Seal mechanism 120 for sealing the drainage does not flow through the crushing unit 20 is installed. In addition, a removal mechanism 121 is installed on the right side of FIG. 25 of the draining portion 12 to remove the rubbish deposited on the upper surface of the draining gate 14 as if it is scraped, thereby reliably transporting the rubbish portion 20. It is.

The seal mechanism 120 and the removal mechanism 21 will be described later in detail.

As shown in Fig. 25, the water draining portion 12 is attached to the upper portion of the pulverization tank 10 (inlet 11) formed of a resin material such as polypropylene. The upper portion is integrally formed with a pair of attachment portions 122 formed so as to protrude upward as shown in Fig. 26. The attachment portions 122 fix the '12' and the grinding chamber 10. The attachment hole 133 is formed in the same manner as that of Fig. 25. In Fig. 25, the same attachment portion 122 and the attachment hole 123 are formed at the rear of the page.

As shown in FIG. 25 and FIG. 26, the water extraction part 12 is provided with the said two attachment parts 122 and the two hook parts 124 which are the engagement parts which are respectively engaged. The hook portion 124 is also a metal having excellent corrosion resistance, and is formed in a plate spring shape, for example, of stainless steel, and a curved portion 125 is formed in which the tip portion thereof is blocked to the upper side of the page.

The hook portion 124 is attached to the outer circumferential wall 126 of the water draining portion 12 located on the front and back side with a fixing member such as a vis, and in a portion facing the curved portion 135 of the hook portion 124. The outer circumferential wall 126 is cut in a quadrangular shape. As a result, the hook portion 124 is elastically deformable in the front and back directions in FIG.

The drain gate 14 is disposed between the drain portion 12 and the pulverization tank 10. The drain gate 14 in this embodiment is formed of resin, such as polypropylene, and as shown in FIG. 25, the circumferential wall part 127 of a circular arc cross section, and the circumferential direction of this circumferential wall part 127 It consists of a pair of support part 128 formed so that it may extend downward from the both ends of the orthogonal direction orthogonal to.

And as shown in FIG. 25, the support part 128 is formed in the one end (right side in drawing) of the circumferential direction of the circumferential wall 127. As shown in FIG. As shown in FIG. 24, the circumferential wall part 127 is larger than the opening area of the blow opening 150 of the grinding tank 10, and the length of the circumferential direction is longer than the length of the blow opening 150. As shown in FIG.

In addition, on the other end side (left side of the figure) in the circumferential direction of the circumferential wall portion 127 on which the support portion 128 is not formed, the sliding portion 129 formed to extend in the same direction as the support portion 128 along this circumferential direction. ) Is formed. In addition, the same sliding part 128 is formed at the rear of the ground in FIG. 25.

Moreover, the support part 128 is provided with the rotating shaft 86 which rotates the draining gate 14, and this rotating shaft 86 is supported by the grinding tank 10 so that rotation is possible, and the draining gate 14 is supported. Is supposed to rotate. The drive mechanism of the drain gate 14 may be performed by a pedal 82 which the above-described rotary motor 15 steps through the control cable 85.

Next, the assembling structure of the draining gate 14, the pulverization tank 10, and the draining part 12 is demonstrated based on FIG. 27 and FIG. 27 is an I-I cross-sectional view in FIG. 25, and FIG. 28 is a K-K cross-sectional view in FIG.

As shown in FIG. 27, the upper part of the grinding tank 10 (intake hole 150) is formed stepwise so that the conveying flow path in the grinding tank 10 becomes smaller toward the upper side in the lower part of the figure. In the figure, it has a flat plate portion 130 extending in the left and right directions, and is formed in a quadrangular cylindrical shape so as to extend upward from an end portion of the flat plate portion 130, and has a quadrangular tube portion 131 constituting the blowing holes 150.

As shown on the left side of FIGS. 27 and 28, the attachment portion 122 and the quadrangular cylinder portion 131 are formed at intervals, and the outer circumferential wall 126 of the water draining portion 12 is formed at this interval. ) And the sliding part 129 of the drain gate 14 are fitted. Incidentally, the left side of Figs. 27 and 28 is not shown but has the same configuration.

That is, the drain gate 14 is such that the circumferential wall portion 127 blocks the intake opening 150, and the sliding portion 129 is sandwiched between the attachment portion 122 and the square tube portion 131. Attach from top to bottom in Fig. 27. Accordingly, the hook portion 124 attached to the water draining portion 12 elastically deforms to the right in FIG. 27, such that the curved portion 125 of the hook portion 124 attaches to the attachment portion 123 of the attachment portion 122. To be fitted in, the water draining portion 12 is fixed to the grinding tank (10). On the other hand, when the water draining portion 12 is removed from the grinding tank 10, the water draining portion 12 is pulled upward in FIG. 27, and the hook portion 124 is bent to the right in the drawing to be easily removed by elastic deformation. Can be.

Next, the sealing mechanism 120 mentioned above is demonstrated based on FIG. 25 and FIG.

The sealing mechanism 120 is provided in the wall surface 135 of the water draining part 12 located in the left side of FIG. 25, FIG. 26, and the press part 133 attached to this wall surface 135, and It consists of a seal part 134 attached to the presser part 133.

The stopper portion 133 is formed to extend along the wall surface 135 with a metal having excellent corrosion resistance, for example, stainless steel. As shown in FIG. 25, the tab part 133 has a curved shape in a circular arc cross section.

The seal portion 134 is a rubber material having excellent corrosion resistance, and is formed of NBR (JIA standard) treated with chlorine. In the present embodiment, the flat rubber material is rounded to form a cylindrical shape. The seal portion 134 is attached to the pawl portion 133 by, for example, an adhesive means such as an adhesive or a fixing member such as a screw.

Next, the function of this sealing mechanism 120 is demonstrated based on FIG.

That is, as shown in FIG. 25, the sealing mechanism 120 is closed when the drain gate 14 closes the intake opening 150 (the drain gate 14 is inserted into the inlet 11 and the crushing unit 20). ), For example, when waste is deposited on the upper surface of the circumferential wall portion 127 (when there is drainage from the sink 1 even if the garbage is not deposited), the water or waste water in the waste There is a possibility of flowing into the inlet 11 along the upper and lower surfaces of 127.

Thus, in the present embodiment, when the drain gate 14 is closing the inlet 11, the end portion (left of FIG. 25) of the circumferential wall portion 127 pushes the seal portion 134 and crushes it to close the circumference. The drainage is prevented from flowing from the top surface to the bottom surface of the wall 127. As a result, the waste and the waste water can be prevented from flowing into the microbial decomposition chamber 40 through the inlet 11, thereby improving the decomposition ability of the microbial carrier 41.

By the way, the seal part 134 functions to prevent the flow of waste and waste water flowing in the left and right directions in the 25th degree from the upper surface of the circumferential wall portion 127, but the above-described problem is perpendicular to the circumferential direction of the circumferential wall portion 127. The same occurs in the end (the front and back side in Fig. 25) in the orthogonal direction.

Thus, in the present embodiment, as shown in Figs. 25 to 28, drainage and garbage flow into the inlet 11 in the outer circumferential wall 126 in the orthogonal direction of the water draining portion 12. The drainage guide part 137 is provided to prevent it from going.

The drain guide portion 137 is formed of a metal having excellent corrosion resistance, for example, stainless steel. As shown in FIG. 26, the drain guide portion 137 is formed in an arc shape in accordance with the shape of the circumferential wall portion 127. The drain guide portion 137 is joined to the outer circumferential wall 126 by, for example, welding.

As shown in Figs. 25 and 26, the drain guide portion 137 is formed to be inclined in the drain portion 12 and to the right in the drawing, and the tip portion and the peripheral wall portion of the drain guide portion 137 are inclined. The top of 127 is slightly spaced apart. And this space | interval can discharge the water in waste to the exterior (outside of the pulverization tank 10) favorably when waste is accumulating on the upper surface of the circumferential wall part 127, and also the perimeter When the waste water from the sink 1 flows into the drain part 12 in large quantities when waste is not accumulating on the upper surface of the wall part 127, between the drain part 2 and the sliding part 129 Inlet (11) is also spaced apart so as not to flow.

Next, the control mechanism 121 mentioned above is demonstrated based on FIG. 25, FIG. 29-FIG. 31. FIG. 29 is a side view seen from the direction of the arrow M in FIG. 30 is a single view of the removal mechanism 121 which removed the removal mechanism 121 from the water draining part 2 in FIG. 29, and FIG. 31 is the side view which looked at FIG. 30 from the arrow L direction in the figure.

As shown in FIG. 25, the removal mechanism 121 is in contact with the upper surface of the circumferential wall portion 127 and removes the retired waste on the upper surface of the circumferential wall portion 127 as if scraped off, and the removal portion. 138 is a holder portion 139, which is a support portion for supporting the water draining portion 12.

The holder portion 139 is formed in a plate shape of resin such as polypropylene. The holder portion 139 in the center portion of FIG. 30 is provided with a hook portion 140 so as to extend upward to attach the removal mechanism 121 to the drain portion 2.

The hook 140 is formed to be elastically deformed so as to be bent in the front and back directions in FIG. The tip end of the hook portion 140 is formed in a hook shape as shown in FIG.

In addition, as shown in FIG. 29, the pair of pushers for pushing the removal mechanism 121 downward in the drawing by the elastic force to the holder portions 139 on both sides of the hook portion 140. The part 141 is integrally formed.

In addition, a substantially C-shaped attachment portion 142 for attaching the removal portion 138 is provided below the holder portion 139.

The removing unit 138 is formed of a rubber material (NBR, JIS standard) that is chlorinated natural rubber, and is formed in a bar shape. As shown in FIG. 31, the lower part of the removing unit 138 is thinner toward the tip. It is. Moreover, as shown in FIG. 29, the upper part of the removal part 138 is formed according to the eye shape of the attachment part 142. As shown in FIG.

The removal part 138 is mounted to the holder part 139 by pushing toward the right from the left side of FIG. 28 so as to enter the attachment part 142.

As shown in FIG. 29, the outer wall surface 144 of the drain portion 12 is formed with a C-shaped hanger 143 for engaging with the hanger 140 of the holder 139. have. The receiving part 143 is formed in a C shape convexly upward from the outer wall surface 144 toward the ground in FIG.

The outer wall surface 144 of the water draining portion 12 has a receiving portion 145 formed to press the pair of pushing portions 141 from above, and the holder portion 139 in cooperation with the outer wall surface 144. A pair of fitting portions 146 are formed to support both ends of the fitting.

Then, the method of attaching the removal mechanism 121 to the water draining portion 12 will be described briefly, and the length receiving portion 143 of the holder portion 139 toward the upper side from the bottom in FIG. 29 is C-shaped hanger. It is elastically deformed and pushed into the part 143. Then, since the distal end of the hanger 143 is hooked, the hanger 40 protrudes from the hanger 143 to the right in the drawing to prevent it from falling out.

As a result, the pair of pushing portions 141 are pressed by the upper portion by the corresponding receiving portions 145, respectively. Then, the pusher 141 is elastically deformed to be bent downward in the figure. Further, both ends of the holder portion 139 are fitted to the corresponding fitting portion 146 and the outer wall surface 144, respectively, to be engaged.

On the other hand, when the removal mechanism 121 is removed from the water draining portion 12, if the removal mechanism 121 is pulled out downward during the 29th degree, the hook portion 140 of the holder portion 139 is easily deformed by elastic deformation. I can pull it out. In addition, for example, when the removal part 138 wants to corrode and replace, after removing the water drain part 12 from the drain opening of the sink 1, as mentioned above, the removal mechanism 121 is pulled out and the removal part ( 138 is pulled out in the left and right direction in FIG. 29 to separate the holder portion 139 and the removing portion 138, and then the other removing portion 138 is attached to the holder portion 139. FIG.

Next, the function of this removal mechanism 121 is demonstrated based on FIG.

As shown in FIG. 25, in the rotational position where the drain gate 14 closes the inlet 11, garbage is deposited on the upper surface of the circumferential wall 127, and the drain gate 14 is moved to the right in the drawing. It is necessary to remove all the accumulated waste from the circumferential wall and drop it to the crushing unit 20 when rotating the dust to the crushing unit 20. That is, in this embodiment, the water draining gate 14 shown in FIG. 24 rotates clockwise so that the removal mechanism 121 moves the garbage on the upper surface of the circumferential wall portion 126 in the left direction in the drawing to remove the garbage. It must fall into the grinding | pulverization part 20.

The reason is that, for example, if the garbage remains on the upper surface of the circumferential wall portion 126 at all, the odor is likely to occur, and there is a problem that the user is uncomfortable.

However, in this embodiment, since the said removal part 138 is attached to the drain part 12 so that it may stick to the upper surface of the circumferential wall part 127 by the pushing part 141, it is attached to the upper surface of the circumferential wall part 127. The accumulated garbage can be dropped in the crushing unit 20 certainly.

Further, in the first embodiment, the waste was scraped off into the inlet by the annular upper leaf seal 17d. However, since the upper leaf seal 17a is annular, the upper leaf seal 17a and the drain gate The contact area with (14) is large. Therefore, especially when the drain gate 14 is closing the inlet 11, the operation force becomes very large when the drain gate 14 is rotated when the inlet 11 is opened.

However, in this embodiment, since the removal part 138 is formed in the shape of a straight rod rather than an annular shape, the operation force at the time of rotation of the drain gate 14 can be reduced.

Next, 3rd Embodiment of this invention is described based on FIG.

A rectangular projection 67 is integrally formed with the casing 22 on the inner wall surface of the iris 22a of the casing 22 of the crushing unit 20. However, the thickness of the projection part 67 is a thickness which can endure the impact force at the time of the thrown garbage. By providing the projections 67 on the inner wall surface of the diaphragm 22a in this way, the lumps of rubbish that have entered the hammer 24a can collide with the projections 67 to be coarsely pulverized, thereby making it easier to crush the garbage. have. In addition, since the waste can be further crushed, the load on the crushing rotor 24 can be reduced, and the residual value of the crushing motor 21 is increased and the crushing motor 21 is locked. Can be prevented.

In addition, since the other structure and operation are the same as that of 1st embodiment, description is abbreviate | omitted.

And the ventilation path 70 is provided with a temperature sensor 73 for detecting the temperature of the air passing through the ventilation path 70, according to the temperature detected by the temperature sensor 73 of the heater 71 By controlling the operation, the microbial carrier 41 contained in the microorganism decomposition chamber 69 is maintained at a predetermined temperature (for example, 40 ° C to 60 ° C).

In this way, by controlling the temperature of the microbial carrier 41 contained in the microbial decomposition chamber 69 by the air heated by the heater 71 passing through the ventilation path 70 provided around the microorganism decomposition chamber ( By the stirring blade 44 in 69, the area | region which cannot be stirred can be reduced. Therefore, the microorganism carrier 41 can be stirred uniformly by the stirring blade 44, and the resolution of the garbage by microorganisms can be raised.

In addition, the bottom surface 74 of the microbial decomposition chamber 69 is made of a punching metal, and condensed water generated in the waste decomposition process by the microorganisms is formed to fall below the housing 68. Condensate accumulated in the lower portion of the housing 68 is discharged to the discharge pipe 18 via the check valve 57.

In addition, since the other structure and operation are the same as that of 1st Embodiment, description is abbreviate | omitted.

The fifth embodiment will be described with reference to FIGS. 34 and 35. FIG.

Although the shape of the drain gate is spherical in the embodiment described above, the part facing the drain gate and the drain gate of the drain part may have the following structure.

A plurality of steps are formed on the surface of the draining gate 75, and portions facing the steps formed in the draining gate 75 at the end of the draining portion 76 are not caught by the step of the draining gate 75. It is formed in the shape of a comb. However, the end portion formed in the comb shape of the water draining part 76 is disposed at a predetermined distance from the surface of the water draining gate 75.

By making the shapes of the water drain gate 75 and the water drain portion 76 in such a shape, the waste having a thin thickness and easily attached to the surface of the water drain gate 75 can be moved to the pulverization portion.

In addition, since the end of the drain portion 76 and the surface of the drain gate 75 are arranged at a predetermined interval, there is no sliding movement resistance when the drain gate 75 is rotated, the drain gate 75 The operating force required to rotate can be reduced. In addition, since the end of the water draining portion and the surface of the water draining gate 75 are arranged at a predetermined interval, wear of the water draining portion can be reduced, and maintenance and repair can be easily performed, and durability can be improved. Can be.

In addition, since the other structure and operation are the same as that of 1st Embodiment, description is abbreviate | omitted.

And although the conveyance pipe 30 was arrange | positioned from the outer periphery of the impeller 25 to the microbial decomposition chamber 40 in 1st Embodiment demonstrated above, as shown in FIG. 36, the outer peripheral part of the impeller 25 is shown. An opening 46 may be provided in an adjacent portion of the facing microbial decomposition chamber 40 and the conveying pipe 30 may be abolished by directly conveying the pulverized waste from the opening 46 to the microbial decomposition chamber 40.

In the above-described embodiment, the plurality of guide plates 26 are provided on the inner wall of the fixed blade 23. However, in view of the processing performance of the pulverized waste, it is preferable to provide the guide plates 26 for purchase. The guide plate 26 may be provided. In addition, in this embodiment, although the heater 60 was provided below the microorganism carrier 41, what is necessary is just a position where the microorganism carrier 41 is heated uniformly and does not touch the stirring blade 44. As shown in FIG.

Next, the sixth embodiment of the present invention will be described based on FIGS. 37 to 40.

In FIG. 37, the garbage disposal apparatus A is provided in the kitchen, and is installed under the sink (not shown). 371 is a grid-shaped strainer with a plurality of small holes attached to a drain in the sink, and consists of a drain to separate the waste and the water contained in the waste. The strainer 371 corresponds to the water draining portion 12 in FIG.

The lower part of the strainer 371 is a conveyance path 372 which conveys waste to the grinding | pulverization part mentioned later, and the upper part of this conveyance path 372 is the inlet 337 into which waste is input. The inlet 337 corresponds to the inlet 11 in FIG. An approximately spherical opening / closing gate 374 is provided between the inlet 337 and the strainer 371. The inlet 373 is opened and closed by opening and closing the open / close gate 374. The opening and closing gate 373 is opened and closed by an electric motor (not shown) or a user's own operating force.

Drainage from the strainer 371 is discharged to the sewer pipe 376 (corresponding to the drain pipe 18 in FIG. 1) through the drain trap (corresponding to the trap portion 13a in FIG. 1) at the outer peripheral portion of the conveying path 372. A drainage path 377 (corresponding to the drainage pipe 13 in FIG. 1) is provided. A part of the drainage path 377 branches in the middle and is connected to the nozzle 373a for washing down the carrier etc. which were deposited at the bottom of the microorganism decomposition part mentioned later. The drainage passage 377 also has a function of an accommodating portion in which the opening and closing gate 374 is accommodated when the opening 337 is opened.

A crushing unit 378 (corresponding to the crushing unit 20 in FIG. 1) is provided at the position below the opening / closing gate 374 and below the conveying path 372. The grinding unit 378 is attached to the grinding rotor 378b with the grinding blade 378a attached to the upper part, the grinding motor 378c for rotating the grinding rotor 378b, and the lower side of the grinding motor. And a rotary blade 378d (hereinafter referred to as an impeller) which rotates in conjunction with the grinding rotor 378b.

On the side (left side of FIG. 37) of the grinding | pulverization part 378, the disassembly tank 110 (corresponding to the microbial decomposition chamber 40 of FIG. 1) located in the housing 379 made of a heat insulating material is arrange | positioned. The decomposition tank 110 contains a microbial carrier 111 (corresponding to the microbial carrier 41 of FIG. 1) (hereinafter, abbreviated as a carrier) carrying aerobic bacteria that withstands high temperature, and crushing unit 378 It is a microorganism decomposing unit for decomposing the crushed waste in the.

A ventilation path 112 is formed around the decomposition tank 110, and the air heated by the heater 113 circulates the ventilation path 12 by the fan 114 so that the interior of the decomposition tank 110 is closed. The decomposition tank 110 is heated to a temperature (eg, 40 ° C. to 60 ° C.) suitable for decomposition of garbage by microorganisms.

115 is a ventilation pump (corresponding to the ventilation pump 50 of FIG. 1), and the decomposition gas generated in the decomposition tank 110 when waste is decomposed through the suction pipe 116 communicating with the interior of the decomposition tank 110. Aspiration is sent to the ventilation hose 117, for example, with vinyl chloride, which is connected to a position which is a sub-side of the drain trap 375 of the drain passage 117.

The bottom surface of the decomposition tank 110 is a water flow-through portion 110a having a water permeability. Decomposed water generated when the waste is decomposed is discharged to the bottom of the housing 379 through the water passage 110a, and discharged to the sewage pipe 376 via the drain trap 118. The bottom part of the housing 379 is provided with a nozzle 377a connected to the branched drainage path 377. The water is discharged from the nozzle 377a so as to be separated from the water passage 110a so as to separate the housing 379. The carrier 111 and the like deposited on the bottom are washed off and discharged to the sewer pipe 376 via the drain trap 375.

The discharge port 119 (decomposition part inlet part in claim) which is in communication with the pulverization part 378 is formed in the position which becomes the outer peripheral part of the impeller 378d of the pulverization part 378 of the wall surface of the decomposition tank 110. . After being crushed by the grinding blade 378a through the discharge port 119, the waste blown by the striking force of the impeller 378d is transferred into the decomposition tank 110. And the discharge port 119 is above the horizontal surface containing the stirring shaft 121 mentioned later among the wall surfaces of the disassembly tank 110 mentioned later, and stirring mentioned later than the vertical surface containing the carrier scraper 123 mentioned later. The blade 122 (corresponding to the stirring blade 44 in Fig. 1) is formed at a position to be a forward side in the rotational direction.

Inside the digestion tank 110, a stirring shaft 121, which is driven by a stirring motor 120, is installed. The stirring shaft 121 has a substantially spiral stirring blade 12 for stirring the carrier 111. ) Is installed.

Moreover, the board | substrate scraping-up part 123 of substantially long external appearance is provided in the position just immediately above the stirring shaft 121 of the inner upper surface of the decomposition tank 110. As shown in FIG. The carrier scraping-out part 123 is provided in the position which opposes the discharge port 119 so that the board surface may extend in the direction which becomes substantially perpendicular to the rotation direction of the stirring blade 122. As shown in FIG. In addition, the lower end 123a of the carrier scraping part 123 is provided to protrude toward the inside of the decomposition tank 110. Then, the carrier scraping unit 123 does not collide with the stirring blade 122 when the stirring by the stirring blade 122 is performed, and the carrier 111 sufficiently lifted by the rotation of the stirring blade 122 is sufficient. A stirring blade 122 is disposed at a predetermined interval (eg, 10 mm) between the trajectory (indicated by a dotted line in FIG. 39) and the lower end 123a that draw the carrier 111 on the stirring table so as to be scraped off. .

Incidentally, an inclined surface is formed at the lower end of the carrier scraping portion 123 so as not to interfere with the rotation of the stirring blade 122.

Next, operation | movement of the garbage disposal apparatus A is demonstrated.

As the waste accumulates in the strainer 371, moisture contained in the waste naturally flows out of the plurality of small holes formed in the strainer 371 to the drainage path 377, and the waste is drained out. When the waste accumulated in the strainer 371 is processed, the opening and closing gate 374 is opened so that the inlet 373 opens by turning on a switch not shown by the user. Next, the strainer 371 is peeled off and the waste accumulated in the strainer 371 is sent from the inlet 373 to the pulverizing unit 378 through the transfer path 372. Subsequently, the opening / closing gate 374 is closed and the grinding blade 378b is rotated by the grinding motor 378c to rotate the grinding blade 378a to finely trash the garbage. The waste crushed by the grinding blade 378a is transferred to the inside of the decomposition tank 110 by the impeller 378d through the discharge port 119.

Garbage sent into the decomposition tank 110 is decomposed by the microorganisms carried on the carrier 111. At this time, the generated decomposition water is discharged to the bottom of the housing 379 through the water passage 110a, and discharged to the sewer pipe 376 via the drain trap 375. In addition, the cracked gas is sucked by the ventilation pump and discharged to the sewer pipe 376 via the exhaust hose 17.

By the way, in order to satisfactorily decompose the waste by the microorganisms, the fan 114 and the heater 113 are operated to keep the temperature of the carrier 111 constant, and at the same time as indicated by the arrow in FIG. 37, stirring The carrier 111 is agitated by rotating the shaft 121 to rotate the stirring blade 122.

However, as the carrier 111 is stirred, the viscosity of the carrier 111 increases due to the water contained in the waste conveyed inside the decomposition tank 110 or the decomposed water generated by the decomposition of the waste. Since the carrier 111 having the increased viscosity adheres to the stirring blade 122, the carrier 111 is lifted by the rotation of the stirring blade 12, and moves toward the forward side of the rotation direction of the stirring blade 122, that is, toward the discharge port 119. I will try to.

However, since the carrier scraper 123 is provided on the inner upper surface of the dissolution tank 110 so as to protrude toward the interior of the dissolution tank 110, the carrier having a high viscosity lifted by the rotation of the stirring blade 122 ( 111 is scraped off by the carrier scraping unit 123. Since the discharge port 119 is formed at a position that is the forward side of the stirring blade 122 in the rotational direction than the carrier scraping portion 123, the stirring blade 122 is in a state where the carrier 111 is scraped off. Since it passes near the discharge port 119, penetration of the carrier 111 into the discharge port 119 can be prevented. Therefore, the waste crushed by the crushing unit 378 can be transferred into the decomposition tank 110 without causing the discharge port 119 to be clogged, so that the operation state of the waste disposal apparatus A can be maintained satisfactorily.

Next, the experimental example which experimented about the change of the penetration amount into the grinding | pulverization part 378 of the carrier 111 with or without the carrier scraping-out part 123 is demonstrated. First, the experimental example examined about the case where the carrier scraping-out part 123 is provided in the position away from the grinding | pulverization part 378 rather than the position which becomes substantially just above the stirring shaft 121 is demonstrated.

Experimental Example 1

An experiment described below was conducted using a waste disposal apparatus having a structure substantially the same as that of the embodiment described above. The amount of the carrier entering the grinding part by changing the distance between the trace drawn by the installation position of the carrier scraping unit and the trailing edge of the carrier scraping unit and the lower end of the carrier scraping unit and agitating the carrier having a higher viscosity than the carrier starting point. ) Was measured. As the carrier, a mixture of wheat flour and grass was added for 1 month, 1 kg of waste was added per day, and the adjusted one was used to have the same viscosity as that of the carrier in a state of use without water (151). And as a parameter of the installation position of a carrier scraping-out part, the distance (Xcm) from the position which becomes substantially directly of a stirring shaft was used. The interval between the lower end of the carrier scraping part and the trace of the stirring blade was 0 cm and 10 cm. The results are shown in Table 1.

As can be seen from the result, the amount of penetration of the carrier 111 into the crushing unit 378 can be reduced by providing the carrier scraping unit 123. If the amount of penetration of the carrier 111 into the crushing unit 378 is 10 ml or less, since the waste can be transported inside the decomposition tank 110 without clogging the discharge port 119, the carrier scraping unit 123 is provided. Regardless of the position, the outlet 111 can be prevented from being blocked by the carrier 111.

However, as the distance from the position where the stirring shaft 121 becomes approximately immediately away, that is, away from the crushing unit 378, the carrier between the inner wall surface of the decomposition tank 110 and the carrier scraper 123. Since the 111 and the garbage easily become clogged, it is preferable that the carrier scraping-out portion 123 is positioned near the position where the stirring shaft 121 is approximately immediately above.

Moreover, the experimental example which examined the case where the carrier scraping-out part 123 is provided in the position which becomes the grinding | pulverization part 378 side rather than the position which becomes substantially just of the stirring shaft 121 is demonstrated.

Experimental Example 2

The same experiment was next performed using the waste disposal apparatus which has a structure substantially the same as embodiment mentioned above. After scraping the carrier, the distance between the trajectory drawn by the installation position and the stirring blade and the lower end of the carrier scraper is changed, and the carrier is stirred for 2 minutes while mixing 3 kg of waste to the carrier 111 used for 50 days. The amount (Vg) of the carrier invaded into was measured. The distance (X ₂ cm) of the carrier scraping part branch from the inner wall surface of the discharging port side of the decomposition tank was used as a parameter of the installation position of the carrier scraping part. Then, the interval between the trace drawn by the stirring blade and the lower end of the carrier scraping portion was set to 0 mm, 5 mm, and 10 mm. The result is shown in FIG. And when the carrier scraping-out part is not provided, the penetration amount of the carrier into the grinding | pulverization part was 33g.

As can be seen in FIG. 40, the carrier 111 penetrates into the grinding | pulverization part 378 into the grinding | pulverization part 378, irrespective of the installation position of the carrier scraping part 123, compared with the case where the carrier scraping part 123 is not provided. The amount decreased. That is, by providing the carrier scraping-out unit 123, it is possible to prevent the discharge port 119 from being blocked by the carrier 111.

And, the shorter the distance from the inner wall surface of the discharge port 119 side of the decomposition tank 110 to the carrier scraping unit 123 may reduce the penetration of the carrier 111 into the crushing unit 378, but stirring In order to reliably scrape off the carrier 111 lifted by the wing 122 by the carrier scraper 123, a predetermined distance between the trajectory of the stirring blade 122 and the lower end of the carrier scraper 123 is predetermined. Since it is necessary to install so that it may become less than a space | interval, when installing the carrier scraping-off part 123 close to the discharge port 119, it is necessary to lengthen the length of the carrier scraping-out part 123. Moreover, since the carrier scraping-out part 123 is arrange | positioned between the grinding | pulverization part 378 and the stirring blade 122, there exists a possibility that it may become an obstacle of the conveyance of the waste to the inside of the decomposition tank 110. FIG. Therefore, as the installation position of the carrier scraping-out part 123, it is preferable that it is near the position which becomes substantially immediately of the stirring shaft 121. As shown in FIG.

In addition, as the installation position of the carrier scraping unit 123, if it is near the position which is approximately immediately above the stirring shaft 121, it is scraped off by the carrier scraping unit 123 to the part which is not stirred by the stirring blade 122. The deposited carrier 111 can be prevented from being deposited. As a result, the support 111 can be sufficiently stirred, so that the state of the support 111 can be kept constant.

Next, the detail of the stirring blade 122 mentioned above is demonstrated. FIG. 41 shows a schematic diagram in which the stirring blade 418 (corresponding to the stirring blade 122 in FIG. 37) is disposed in the microbial container 415 (corresponding to the digestion tank 110 in FIG. 37). It was.

The stirring blade 418 is formed of the above-mentioned stainless steel. As shown in FIG. 41, the stirring blade 418 is able to rotate to the up-down direction by the rotating shaft 440 arrange | positioned in the horizontal direction. Since the waste from the impeller 378d is sent to the upper part of the microbial carrier 431 (corresponding to the microbial carrier 111 of FIG. 37), the waste and the microbial carrier 111 can be stirred well. .

The rotating shaft 440 is made of stainless steel described above. The stirring blade 418 is freely supported by the microbial vessel 415 for rotation. A pulley is attached to one end (left side in the figure) of the rotary shaft 440.

Further, the bottom portion (punching metal 426) of the microorganism container 415 is formed to be a concentric circular arc surface with the rotational trajectory of the stirring blade 418 as shown in the forty-first illustration.

As shown in FIG. 41, one stirring blade 418 is provided in the both ends of the direction orthogonal to the axial direction of the rotating shaft 440, respectively, and it is set as 418a and 418b, respectively. In addition, two stirring members 418 are provided in the microbial container 415 side by side in the axial direction of the rotation shaft 440.

First, the stirring blade 418a will be described in detail. FIG. 42 is a view seen from the direction C in FIG. 41, FIG. 43 is a view seen from the direction D in FIG. 43, and FIG. 44 is a view seen from the top to the bottom in FIG.

As shown in FIG. 41, the stirring blade 418a is integrally formed with the pair of arm parts 442a and 442b attached to the rotating shaft 440. As shown in FIG. The arm parts 442a and 442b are formed in board shape, and the board surface is extended to 90 degrees in the circumferential direction of the rotating shaft 440 toward the axial direction of the rotating shaft 440, and is attached to another position.

In the present embodiment, as shown in FIG. 41, end portions of the arm portions 442a and 442b are bent to form bent portions 442c. The bent portion 442c is attached to the rotating shaft 440 by a bis (not shown) as a fixing means. 450 shown in FIGS. 42-44 is a bission hole into which the said screw is fitted.

Then, a board-shaped stirring portion 443 is provided to substantially connect the tip ends of the arm portions 442a and 442b to stir the waste and the microbial carrier 431. As shown in FIG. 41 and FIG. 42, this stirring part 443 is formed by the board-shaped member being bent. Therefore, this stirring part 443 comprises the bending part mentioned in a claim.

Here, before explaining this bending method, the stirring portion 443 has a function of stirring the microbial carrier 431 and the waste, and is deposited near the upper side of the water passage 416a of the punching metal 416. To scrape the old microbial carrier 431 and garbage.

FIG. 45 schematically shows the arrangement relationship with the punching metal 416 when the stirring portion 443 of the stirring blade 418a located at the uppermost portion of FIG. 41 is rotated to the lower portion of the microorganism container 415. FIG. It is shown in cross section.

As shown in FIG. 45, the stirring part 443 is inclined so as to exert a force upwards in the horizontal direction on the microorganism carrier 431 and the garbage in the vicinity of the decomposable drainage hole 416a. As a result, the microorganism carrier 431 and the waste deposited on the upper part of the decomposable drainage hole 416a by the stirring unit 443 are scraped upward, thereby preventing the decomposing drainage hole 416a from being blocked. have.

In addition, in this embodiment, the opening surface (inner surface of the punching metal 416) of the some water-discharge drain hole 416a becomes the rotational trace of the stirring part 443, and the concentric circular arc surface, The stirring part 443 Since the rotation rotates with the same clearance as the opening surface at all times, the clogging of the decomposable drainage hole 416a can be effectively reduced over the opening area. As a result, the drainage of the decomposed water can be much improved.

Moreover, according to the examination of the present inventors, microorganisms are effectively controlled by setting the shortest distance between the end of the stirring part 443 shown in FIG. 45 and the opening surface of the punching metal 416 (opening surface of the upper passage hole 16a) within 15 mm. It can be seen that the carrier 431 and the waste can be scraped off, thereby reducing the clogging of the dewatering drain hole 416a. When the shortest distance is within 10 mm, clogging can be further reduced, and the present embodiment sets the distance to 10 mm.

In the present embodiment, the following effects can be obtained by the bending method of the stirring section 443.

As shown in FIG. 45, the bending method of the stirring part 443 has an acute angle θ from the front of the rotation direction to the rear of the rotation direction on the basis of the tangent of the rotation direction of the stirring blade 418 (this embodiment). 27 degrees).

That is, when the stirring blade 418a at one end of the rotating shaft 440 rotates in the E direction in FIG. 41, the microbial carrier 431 and the waste are applied to the other end of the rotating shaft 440. Therefore, when the stirring blade 418a rotates in the E direction in FIG. 41, the microorganism carrier 431 and the garbage are left to the left in FIG. 41 while being stirred.

Moreover, the stirring blade 418b is also formed in the same idea as the said stirring blade 418a, and the thing of the same function attached | subjected the same code | symbol. That is, the stirring unit 443 has a function of scraping upward of the microbial carrier 431 and the waste in the vicinity of the dewatering drainage hole 416a, and has a function of letting out the microbial carrier 431 and the waste while stirring. For reference, FIG. 46 shows the stirring blade 418b seen from the direction of arrow (c) in FIG.

Note that when the stirring blade 418b on the other end of the rotating shaft 440 rotates in the E direction in FIG. 41, the microbial carrier 431 and the waste are applied to one end of the rotating shaft 440. Therefore, when the stirring blade 418b rotates in the E direction in FIG. 41, the microbial carrier 431 and the garbage are stirred and are discharged to the right in FIG. 41.

That is, since the two stirring blades 418a and 418b are installed in the direction orthogonal to the axial direction of the rotation shaft 440, as described above, the microbial carrier 431 and the waste are stirred as follows.

Hereinafter, the waste disposal process by this control apparatus 600 is demonstrated in order briefly. FIG. 50 is a block diagram showing this waste disposal process.

First, when the waste accumulates in the drain portion 504, water in the waste flows out into the discharge path 508 from a plurality of small holes naturally formed in the drain portion 504, thereby draining the waste water.

[Blocka]

When the user processes the waste accumulated in the water draining part 504, first stepping on the stepping pedal, the opening / closing gate 507 is operated to open the inlet 506. At this time, the water draining part 504 is peeled upward, and the waste in the water draining part 504 is dropped into the crushing part 511 from the inlet 506 through the transfer path 505. Subsequently, the foot is released from the pedal and the inlet 506 is closed by the opening / closing gate 507.

[Block b, c, crush control, stirring control]

Then, the control device 600 determines that the opening / closing gate 507 is closed when the inlet 506 is opened, and automatically opens the crushing motor 513 of the crushing unit 511 for a predetermined time (30 seconds). ) Rotate drive (crushing control). At the same time, the stirring motor 520 is driven for 2 minutes (stirring control).

The opening / closing state of the opening / closing gate 507 is detected by a switch element (not shown). In addition, the crushing motor 513 is stopped when the pedal which is pressed again during this two minutes is operated.

Then, the waste is crushed finely by the crushing blade 512, the crushed waste is conveyed to be ejected to the left side of the 47 by the impeller 530, is sent to the microbial container 515 of the decomposition unit 514. . At this time, by driving the stirring motor 520, the stirring blade 518 is rotated and the garbage and microbial carrier 531 sent into the microbial container 515 is stirred.

As described above, the stirring motor 520 is operated even when the pedal is operated as described above, while operating for 2 minutes every hour as described above even if the pedal is not pressed.

The decomposition gas generated by the decomposition is discharged to the sewer pipe 526 by the ventilation pump 524. When the waste disposal apparatus 501 is not used, the wastewater is sent from the discharge passage 509 located on the right side in FIG. 47 to the sewer pipe 526.

However, since foreign matters such as slimy and fine microbial carriers 531 are mixed in the decomposed water, foreign matter adheres and deposits on the upper surface of the inclined surface 532a, thereby degrading drainage of the decomposed water.

When a large amount of water enters the microbial container 515, foreign matters such as the fine trash or undecomposed calcium flow out from the water passage hole 516a by this water, and only this foreign matter is inclined surface 532a. There is a problem in that it is deposited on and deteriorates the drainage of decomposed water.

As a specific example, (1) When, for example, garbage and water are transferred together from the inlet 506 to the crushing unit 511 (the water not shown in the upper part of the sink 502 is not used), the present embodiment In particular, since the waste inlet 506 is provided below the drain hole 503, the microbial container 515 is opened through the inlet 506 with a large amount of drainage using the water supply with the gate 507 open. This is the case when you break into.

Therefore, in this embodiment, as shown in FIG. 47, the foreign matter flows down by providing a water channel 521 for inducing water on the inclined surface 532a (decomposition water drain passage 517).

Hereinafter, this channel 521 will be described in detail with reference to FIGS. 47 to 49. As shown in FIG. 47, the channel 521 communicates with the drainage hole 503, and is comprised so that a part of the wastewater which flowed into the said drain pipe 509 may be guide | induced to the said inclined surface 532a.

As shown in FIG. . The stainless pipe 521b extends from the top to the bottom as shown in FIG. Further, the downstream portion of the stainless pipe 521b is supported by the step portion 532b formed in the outer container 532, as shown in FIG. In addition, the microorganism container 515 is not shown in FIG. 49, and the punching metal 516 is shown for clarity by description.

The downstream end of the stainless pipe 521b is crushed and blocked. As shown in FIG. 48, the stainless pipe 521b is arrange | positioned on the bottom surface of the outer container 532 (decomposition water drainage path 517). A water outlet portion 521c having a diameter of 10 mm is formed in the outer circumferential portion near the downstream end of the stainless pipe 521b as shown in FIG. This water outlet 521c is located at the most upstream side of the inclined portion 532a at the center of the two punching metals 516 in the vertical direction in FIG.

In addition, the water outlet 521c is configured to drain the drainage from the drain hole 503 from the inclined upper portion of the inclined portion 532a (upstream of the decomposed drainage passage 517) (the downstream of the decomposed drainage passage 517).

First, tap water (drainage) from the tap (not shown) installed at the upper portion of the sink 502, where water is performed in the sink 502, flows down into the drain hole 503 of the sink 502. Then, after passing through the water draining part 504, after flowing into the drain passage 505, it flows into the discharge pipe 509. Subsequently, a part of the wastewater flowing into the discharge pipe 509 flows into the water channel 521.

And the drainage which flowed into the channel 521 is discharged from the water outlet part 521c of the stainless pipe 521b toward the inclined lower part from the inclined upper part of the inclined surface 532d. As a result, the drainage discharged from the water outlet 521c flows smoothly along the inclined surface 532a from the left side to the right side in FIG. 48 to effectively flow down the foreign matter deposited on the inclined surface 532a, and the sewer pipe 526 together with the foreign matter. Flows into.

As a result, in the present embodiment, by effectively using the drainage, the amount of foreign matter deposited on the inclined portion 532a is reduced, and the decomposed water flows into the sewer pipe 526 reliably. In addition, in this embodiment, since the waste disposal apparatus 501 was arrange | positioned under the sink 502, the wastewater channel 517 and the drain hole 503 can be made to approach, and the flow path of the water channel 521 can be made easy. Can be.

And a judging means (block a) for judging whether or not it has been conveyed inside, and when it is determined that the garbage is transferred to the microbial container 515 by this judging means, the stirring blade 518 is operated for a predetermined time (2 minutes) (block b).

Thereafter, as the washing control indicated by block d in FIG. 52, the solenoid valve 546 is controlled by the controller 600 such that the valve is opened for about 10 seconds after the stirring motor 520 is stopped.

As a result, when the waste is transferred to the microorganism container 515, the decomposed water and the waste are agitated by the stirring blade 518, and when the decomposed water is generated, the electronic valve part 546 is opened in advance so that the water passage 521 is opened. Since the can be opened, foreign matter deposited on the inclined surface 532a from the water channel 521 can flow down.

In addition, in this embodiment, since the water supply 521 is connected to the water supply pipe 545 compared with the said 7th embodiment, the foreign material accumulated on the inclined surface 532a can flow down favorably by using water pressure. In addition, what is necessary is just to determine the quantity of water which flows into this channel 521 suitably.
