Description

Garbage Disposal Unit

The present invention relates to a food waste processing apparatus for processing food waste from a home kitchen.

As a conventional food waste disposal apparatus, as described, for example, in Japanese Patent Application Laid-Open No. 3-110099, after crushing the food waste put into the inlet formed in the sink bottom of the kitchen with a disposer, this grinding is performed. The crushed food waste is introduced into the lower part of the dewatering screen, dehydrated while being conveyed to the upper side of the dewatering screen by a conveying screw provided in the dewatering screen, and discharged to the outside at an outlet formed at the upper end of the dewatering screen.

Such a food waste disposal apparatus processes the crushed food waste introduced into the dewatering screen by operating the conveying screw with the crushing operation by the disposer.

However, in the above-described conventional food waste disposal apparatus, there is no problem in the case of treating the normal food waste by operating the disposer as described above, but, for example, fine food waste such as chaff is flown into the inlet. In the case of sending, although the disposer is stopped, it may be introduced through the disposer to the dewatering screen side.

At this time, since the disposer is stopped and the conveying screw does not operate, fine food waste, such as dregs, remains around the inlet of the dehydration screen. In this way, when food wastes remain around the inlet, it causes clogging due to adhesion, which requires complicated work to remove the obstructions, and thus there is a problem that food waste cannot be disposed of smoothly.

The present invention has been made in view of the above-described problems, and can prevent fine food waste from remaining around the inlet of the dehydration screen, thereby preventing blockage due to the adhesion or attachment of such food waste, and smoothing the food waste. It is an object of the present invention to provide a food waste disposal apparatus that can be disposed of easily. In addition, it is an object of the present invention to provide a food waste disposal apparatus that is very suitable for small-scale food waste disposal at home or the like, with a reduction in operating cost.

Further, the transfer motor 53 is controlled to rotate forward for a predetermined time irrespective of the operation of the disposer 2 described above, based on the detection of the water level sensor 6.

The water level sensor 6 is arranged at approximately an intermediate position of the dewatering screen 3 as shown in FIGS. 2 and 3. Specifically, the water level sensor 6 is for detecting that water introduced into the dewatering screen 3 through the inlet 11 reaches a predetermined level, and the water level W of the water accumulated in the case 4 (See FIGS. 1 and 3) is provided on the dewatering screen 3 so as to be located slightly above. That is, when water flows into the dewatering screen 3, since the level of the standing water rises primarily, this is detected by the water level sensor 6.

In addition, the water level sensor 6 is integrally fixed by appropriate fixing means in a state where the detection unit 61 is inserted into the cutout portion 3a formed on the dewatering screen 3, Thereby, the said detection part 61 is arrange | positioned so that the front-end | tip of the screw part 52 of the conveyance screw 5 may slide-contact. As the water level sensor 6, a capacitive type, energized type, or other type of thing is used. The upper end opening of the dewatering screen 3 is pressed in the upper side by the upper surface A of the main body of the apparatus. A discharge port 33 is formed at an upper end of the introduction port 31 and the dewatering screen 3 to be the target position. The discharge port 33 is dehydrated while being conveyed upward by the conveying screw 5.

That is, since the upper opening of the dewatering screen 3 is blocked by the upper surface A as described above, the pulverized food waste is conveyed upward by the conveying screw 5, and the conveying direction thereof is the discharge port 33. Is forcibly converted to the horizontal direction and discharged by the action of the protrusion 55 of the conveying screw 5 described later. The opening of the discharge port 33 is predetermined as shown in FIG. In addition, the pair of guide pieces 34 and 34 guides the pulverized food waste discharged from the discharge port 33 to the chute 81 described later on both left and right sides of the discharge port 33. On the other hand, as shown in FIG. 4, a mountain-shaped protrusion 55 is integrally formed with the shaft portion 51 at the upper end of the conveying screw 5, and this protrusion 55 is formed. ) The front end of the slide) contact the inner wall of the upper end of the dewatering screen (3) Accordingly, as the conveying screw 5 rotates, the protrusion 55 rotates while slidingly contacting the inner wall of the upper end of the dewatering screen 3 to convey the crushed food waste which is conveyed upward by the conveying screw 5. While compressing to an appropriate level, the pulverized food waste can be forced out to the outside through the discharge port 33.

The case 4 is provided with a drain 41 for draining the water separated from the pulverized food waste by dehydration when the pulverized food waste is conveyed upward by the conveying screw 5. The drain port 41 is an overflow type drained through the drain port 41 when the water separated by the dehydration exceeds a predetermined level, and is not shown through the drain pipe 42 connected to the drain port 41. Not drained to the outside of the drain groove.

The case 4 is partitioned into the space part 43 in which the said drain hole 41 is arrange | positioned by the 1st partition board 44, and the said dehydration screen 3 side. In other words, the first partition plate 44 divides the case 4 into the drain port 41 side and the dewatering screen 3 side. The lower end of the first partition plate 44 is always submerged in the water accumulated in the bottom portion of the case 4, whereby the space portion 43 in the case 4 is completely enclosed with the dewatering screen 3 side. It is in a state.

Moreover, the 2nd partition board 45 is formed in the bottom part of the case 4 in the dehydration screen 3 side as shown in FIG. As shown in FIG. 6, this second partition plate 45 is arranged in pairs in the shape of an eight shape on both left and right sides of the dewatering screen 3 with the introduction port 31 interposed therebetween. The through hole 45a is formed in the board 45 at the lower end part, respectively.

The height of the upper end of the second partition plate 45 is approximately equal to or slightly higher than the height of the lower end of the first partition plate 44. Accordingly, the water that accumulates on the side of the dehydration screen 3 flows over the top of the second partition plate 45 toward the first partition plate 44 while the clear water of the upper portion flows into the first partition plate 44 and the bottom of the dewatering screen 3 side. The sediment (solid content of oil, etc.) that accumulates in the portion is introduced into the first partition plate 44 through the through hole 45a of the second partition plate 45 together with water.

Moreover, the float switch 16 is provided in the space part on the side of the dehydration screen 3 between the said 1st partition board 44 and the said 2nd partition board 45. As shown in FIG. The float switch 16 is for detecting the level of water that accumulates in the case 4, and includes a float portion 161 and a limit switch 162 that are swingable.

As shown in Fig. 7, the float portion 161 includes a rod 161a whose one end is swingably supported up and down by an attachment member 163 supported on the upper surface A of the apparatus main body, and the rod 161a. It consists of the float 161b provided in the front-end | tip part, and the float 161b swings the rod 161a up and down by following the fluctuation of the water surface.

The limit switch 162 is provided above the one end of the rod 161a of the attachment member 163, and the contactor 162a is provided on the refractive portion 161c formed near the one end of the rod 161a. It can be contacted. Therefore, when the water level rises and reaches a certain water level, the rod 161a swings upward as shown by the dashed-dotted line in FIG. 7, and the deflection portion 161c comes into contact with the contactor 162a, thereby limiting the switch 162. ) Is turned ON to detect that the water level is high. This detected water level is a danger level which becomes a dangerous state which will leak water outside in the case 4, if the water level rises further, and this dangerous water level is detected by the limit switch 162. FIG.

When the limit switch 162 detects the dangerous water level in this way, the operation of the disposer 2 is stopped.

On the side of the case 4 facing the outlet 33 is disposed a processing chamber 8 for decomposing the dehydrated crushed food waste, and the dehydrated crushed food waste is discharged through the chute 81 at the outlet 33. It slips and falls to the bottom part in the process chamber 8.

At the bottom of the processing chamber 8, a processing tank 82 for storing and processing the injected crushed food waste is provided, and a predetermined amount of decomposition chips is stored in the processing tank 82 in advance.

In addition, a stirring member 83 is provided in the processing tank 82. The stirring member 83 is composed of a stirring shaft 84 horizontally installed at a predetermined height in the processing tank 82 and a plurality of stirring bars 84a protruding outwardly from the stirring shaft 84. When the stirring member 83 is rotated by the driving of the stirring motor 85 connected to one end of the 84, the crushed food waste introduced into the processing tank 82 by the tip of the stirring bar 85 and the processing tank 82 The decomposition chip stored in the) is stirred.

The cracked chip is used to promote fermentation of the crushed food waste, for example, wood chips, rice hulls and the like are used.

In addition, a temperature adjusting heater 86 is provided below the bottom of the processing tank 82. The stirring member warms the crushed food waste and the decomposition chip in the processing tank 82 by the heater 86. In addition to the stirring action of (83), it promotes the decomposition treatment of the crushed food waste.

The processing tank 82 is provided with a sensor (not shown) which detects that the processing material gradually stored in the processing tank 82 is filled by the decomposition processing of the crushed food waste.

The processing chamber 8 is connected with first exhaust means 18 for releasing odors and moisture generated in the processing chamber 8. The first exhaust means 18 communicates with an exhaust port 87 formed in the upper portion of the processing chamber 8 and a space 43 whose one end is connected to the exhaust port 87 and whose other end faces the drain port 41. The first exhaust pipe 88 and an exhaust fan 89.

Specifically, as shown in FIG. 8 and FIG. 9, the first exhaust pipe 88 has a screw member (not shown) at the connection portion 184 of the apparatus main body whose one end portion communicates with the exhaust port 87 through the exhaust fan 89. It is detachably connected by 188a, and the other end is communicated with the space part 43 via the 1st coupling 185. As shown in FIG.

The first coupling 185 is a two-way coupling in which both ends are opened, and one end of the first coupling 185 is detachably connected to the other end of the first exhaust pipe 88 by a screw member 188b, and the other end of the first coupling 185 is detachable. It is configured to be detachably connected to the exhaust inlet 43a leading to the space 43.

On the other hand, the processing chamber 8 is provided with an air supply port (not shown) for introducing air from the outside, and a dust removal filter (not shown) is detachably installed in the air supply port.

Therefore, the odor and water generated in the processing chamber 8 introduced into the space 43 through the exhaust port 87 and the first exhaust pipe 88 are sealed by the space 43 with the dewatering screen 3 side. Therefore, it is exhausted to the outside through the drain pipe 42 with the water overflowing from the drain port 41 without leaking to the dehydration screen 3 side.

In addition, the first exhaust means 18 may constitute the second exhaust means 19 which directly exhausts the outside by converting the first coupling 185 into a second coupling 191 as shown in FIG. It is possible.

The second coupling 191 is a three-way coupling in which the lower side and the left and right sides are opened, and a lower opening end is detachably connected to the exhaust inlet 43a, and an opening end on the left side of the first exhaust pipe ( It is detachably connected to the other end of the 88 by the screw member 188b, and is detachably connected to the one end of the 2nd exhaust pipe 192 through which the right opening end communicates with the outside by the screw member 192a. . One end of the first exhaust pipe 88 is detachably connected to the connecting portion 184 of the apparatus main body by the screw member 188a as described above.

Therefore, by using the second coupling 191, by closing the lower opening end of the second coupling 191 with a suitable closing member, the odor or moisture generated in the process chamber 8 to the first exhaust pipe (88) can be directly exhausted to the outside via the second exhaust pipe (192). Further, by using the lower opening end of the second coupling (191) in an open state, odors generated in the processing chamber (8) The water may be diverted to the outside and the drain 41 to exhaust.

That is, by appropriately using the first coupling 185 and the second coupling 191, a path for exhausting the exhaust path through the drain port 41, a path for directly exhausting the outside of the processing chamber 8, and these The path to exhaust through both sides can be selected according to the installation situation.

In addition, the process chamber 8 and the said case 4 comprised as mentioned above are integrally formed in this embodiment.

Here, the rotation sensor 56 is provided at the lower end of the transfer motor 53. For example, an optical sensor is used for this rotation sensor 56, and the conveyance speed of the crushed food waste by the conveying screw 5 is detected by detecting the rotation speed of the fan (not shown) connected to the rotation shaft of the conveying motor 53. As shown in FIG. It is configured to detect indirectly.

Next, the processing of the food waste by the food waste processing apparatus comprised in this way is demonstrated.

Food waste from the home and the like is introduced with water to the inlet 11 of the sink (1) of the kitchen. The food waste put into the inlet 11 is crushed by the disposer 2 and then into the dewatering screen 3 from the inlet 31 of the dewatering screen 3 through the communication passage 22 together with the water. It is introduced and conveyed to the upper side on the upper surface of the screw portion 52 of the conveying screw 5 by the forward rotation of the conveying screw 5 operating in conjunction with the operation of the disposer 2. As the food waste is conveyed to the upper side, the water contained therein is separated from the dehydration hole 32 to the outside of the dewatering screen 3 so that the waste is smoothly discharged from the discharge port 33 to the processing chamber 8 through the chute 81. do.

Therefore, the pulverized food waste can be discharged quickly and smoothly from the discharge port 33 to the processing chamber 8, and the processing chamber is discharged by the first evacuation means 18 or the second evacuation means 19 or both evacuation means. By exhausting the malodors and the like in (8), it is possible to ensure a pleasant surrounding environment in which the malodors caused by the crushed food waste do not wander around.

On the other hand, the water discharged to the outside of the dewatering screen (3) through the dehydration hole 32 is drained to the outside of the case (4) through the drain pipe 42 in the drain (41).

When separating the pulverized food waste and water in the dewatering screen 3 in this way, the pulverized food waste is inserted between the tip of the screw portion 52 of the conveying screw 5 and the inner wall of the dewatering screen 3. When the conveying speed of the crushed food waste by the conveying screw 5 is lower than a preset value due to the like, the rotation sensor 56 detects a decrease in the rotational speed of the rotating shaft of the conveying motor 53 in this case. Detect indirectly.

Therefore, in the control apparatus which is not shown in figure, based on the detection result of the rotation sensor 56, the conveyance screw 5 is rotated by the predetermined rotation speed (for example, three revolutions), and then rotates forward again. And when the rotation sensor 56 detects the fall of the rotation speed of the rotation shaft of the conveying motor 53 again at the time of forward rotation, the conveyance screw 5 reversely rotates as mentioned above. That is, the forward rotation operation and the reverse rotation operation are repeatedly executed until the rotation axis of the transfer motor 53 is forward rotated at a predetermined rotation speed or more.

By driving control of the conveying screw 5 in this way, that is, the conveying screw 5 is actually for releasing this only when the crushed food waste is sandwiched between the screw portion 52 and the inner wall of the dewatering screen 3. By reverse rotation, dehydration can be carried out while conveying the crushed food waste to the upper side efficiently.

The dehydrated pulverized food waste discharged from the discharge port 33 through the chute 81 to the processing chamber 8 is agitated with the disintegrating chip very well by the stirring member 83 in the processing tank 82. The fermentation is rapidly decomposed by heating by the heater 86.

In the decomposition treatment, odor and moisture generated in the processing chamber 8 are introduced into the space 43 in the case 4 through the first exhaust pipe 88 at the exhaust port 87 by the exhaust fan 89. In addition, the water is discharged to the outside through the drain pipe 41 through the drain pipe 42.

In the above decomposition treatment step, when the first coupling 185 is used, the odor and moisture generated in the processing chamber 8 are discharged from the exhaust port 87 by the first exhaust pipe 88 and the first coupling 185. It is introduced into the space 43 in the case 4 through, and is discharged to the outside with the drain through the drain pipe 42 in the drain 41. In addition, in the case of using the second coupling 191 which closes the lower opening end portion, the exhaust port 87 allows the first exhaust pipe 88, the second coupling 191, and the second exhaust pipe 192 to be used. It is exhausted directly to the outside. In addition, when using the 2nd coupling 191 which opened the lower opening end part, the drain pipe 42 in the drain port 41 through the 1st exhaust pipe 88 and the 2nd coupling 191 in the exhaust port 87. At the same time, the exhaust gas is exhausted to the outside of the apparatus main body through the second exhaust pipe 192.

At this time, the moisture adjuster is dried and the moisture absorbed from the crushed food waste is exhausted to the outside as described above, so that the moisture of the newly crushed trash can be absorbed again by the moisture adjuster. That is, the moisture regulator stored in the treatment tank 82 can be used repeatedly for a long time. Therefore, since it is not necessary to frequently replenish the water conditioner, the running cost can be greatly reduced.

The processed material is gradually stored in the processing tank 82 by the decomposition process of the pulverized food waste in the processing chamber 8 described above. When the processed material is filled in the processing tank 82, a sensor (not shown) Detect this. If this detection is detected, the operation is stopped, the processed material in the processing tank 82 is taken out of the processing chamber 8 through an opening / closing door (not shown), and a new predetermined amount of disintegrating chip is introduced into the processing tank 82. Subsequently, as described above, the pulverized food waste is decomposed.

In this way, when the disposer 2 is operated to introduce the crushed food waste into the dewatering screen 3 together with the water, the crushed food waste is treated as appropriate as described above. On the other hand, even if the food waste is thrown into the inlet 11, the operation of the disposer 2 may be forgotten. For example, it may be left as it is in the state in which the dregs and the like are put in. In such a case, the small and fine food wastes are originally passed to the dewatering screen 3 through the disposer 2 together with the incoming water without being crushed. Will be introduced.

At this time, in the dehydration screen (3), the water level rises primarily due to the inflow of water, and the water level sensor (6) detects the increase of the water level. On the basis of the detection of the water level rise, the conveying screw 5 is rotated forward by the conveying motor 53 for a predetermined time, thereby removing the fine food waste introduced around the inlet 31 of the dehydrating screen 3. ) Is discharged upward from the discharge port 33 and discharged from the discharge port 33 to the processing chamber 8. In other words, the operation of the conveying screw 5 in this case is set to the time as long as the conveying screw 5 can discharge the fine food waste.

Thus, regardless of the operation of the disposer 2, by operating the conveying screw 5 for a predetermined time in accordance with the detection of the water level rise, the fine food waste around the inlet 31 of the dewatering screen 3 Since the residence can be prevented, it is possible to prevent clogging due to the adhesion or adhesion of such food waste and to prevent the occurrence of odor.

For example, when debris or the like is attached to the dewatering screen 3, the dewatering hole 32 is blocked. Therefore, when a large amount of water flows into the dewatering screen 3 in this state, the dewatering screen 3 is raised. This causes the problem that the discharge port 33 leaks to the processing chamber 8 side, but the above-mentioned operation of the conveying screw 5 can prevent the blockage due to the attachment of food waste. In this way, food waste can be disposed of smoothly.

In addition, the detection unit 61 of the water level sensor 6 is brought into sliding contact with the tip of the screw unit 52 of the transport screw 5 so that the surface of the detection unit 61 is always on the surface of the detection unit 61 by the operation of the transport screw 5. I'm cleaning. Therefore, the fall of the sensitivity by the adhesion of the deposit to the detection part 61 can be prevented, and it can operate smoothly by preventing the malfunction by the fall of the sensitivity.

And the food waste disposal apparatus comprised in this way is equipped with the alarm means which alerts this when the water level sensor 6 does not operate for a predetermined time. As this alarm means, a buzzer, a lamp, etc. may be operated, and what is necessary is just to set suitably according to a living situation, for example, to notify through a communication means. In addition, the time when the water level sensor 6 does not operate, which is alerted by the alarm means, may be set at any time according to the living situation. You can do it. Therefore, by providing the alarm means in this way, it is possible to grasp the living situation of the elderly, etc. living alone. In the present embodiment, the projection part 55 for sliding contact with the inner wall of the dewatering screen 3 at the upper end of the conveying screw 5 is provided. On the other hand, the opening width L in the transverse direction of the discharge port 33 is 1/5 to 1/15 of the circumferential length of the dewatering screen 3 so as to improve the dewatering treatment capacity of the crushed food waste. In addition, the discharge port 33 to facilitate the discharge of the crushed food waste. As another embodiment for smoothly discharging the crushed food waste to the outside, as shown in Figs. 11 and 12, the upper opening of the dewatering screen 3 is covered with a cover material 35 having a discharge port 33 formed therein. It may be configured to discharge the crushed food waste dehydrated while being conveyed upward by the conveying screw 5 to the outside from the discharge port 33. Specifically, the upper end of the conveying screw 5 is shown in FIG. As described above, the cam member 56 is integrally provided with the shaft portion 51, and the rake member 7 is provided so as to be able to swing in the horizontal direction in close proximity to the cam member 56. The rake member 7 has its proximal end 71 supported by the vertical pin 73 at the upper periphery of the dewatering screen 3 so as to be able to swing in the horizontal direction, and its distal end 72 has the cam member 55. ) Is held by a non-illustrated support member such that the circumferential surface of the circumferential surface is always in sliding contact. With this configuration, the tip end portion 72 of the rake member 7 moves around the discharge port 33. ), The rocking contact of the circumferential surface of the cam member 56 in accordance with the rotation of the < RTI ID = 0.0 > camera < / RTI > The crushed food waste is forcibly scraped out of the discharge port 33 by an operation of moving toward the discharge port 33 from the shaft center side of (5). As the rake member 7 scrapes the pulverized food waste in this way, the pulverized food waste can be smoothly discharged to the outside of the discharge port 33. In addition, the rake member 7 also has an action of peeling off the ground food waste adhering to the circumferential surface of the cam member 56 by sliding contact of the tip portion 72.

As described above, according to the food waste disposal apparatus of the present invention, by operating the conveying screw for a predetermined time based on the detection by the water level sensor, regardless of the operation of the disposer, it is possible Preventing food waste Therefore, it is possible to prevent clogging due to the adhesion or adhesion of the food waste and to prevent the occurrence of odor, thereby smoothly treating the food waste.

Then, the ground food waste in the processing chamber is properly agitated with the moisture regulator by the stirring means in the treatment tank, so that the moisture is absorbed by the moisture regulator and the amount of water is adjusted, and at the same time, the fermentation is accelerated by heating by the heating means. Corrosion decomposition treatment reduces weight. Therefore, it is possible to completely dispose of food waste from homes and the like, it is convenient to reduce the labor, such as waste discharge at the time of garbage collection. In particular, since the moisture of the pulverized food waste absorbed by the water conditioner together with the odor and water generated in the processing chamber is also exhausted to the outside by the exhaust means, it is used repeatedly for a long time without frequent replenishment of this water conditioner. This can significantly reduce the running cost.

In addition, by supplying air into the processing chamber by the blowing means, it is possible to further accelerate the corrosion decomposition treatment of the pulverized food waste.

In addition, since the detection portion of the water level sensor is in sliding contact with the tip of the screw portion of the conveying screw, the slide contact can always clean the surface of the detection portion, whereby the sensitivity of the detection portion can be maintained satisfactorily and the sensitivity decreases. It can be operated smoothly by preventing malfunction.

By selecting one side or both sides of the exhaust means through which the exhaust means is exhausted through the drain port and the second exhaust means which exhausts directly to the outside of the processing chamber, an optimum exhaust path is selected according to the installation situation. Can be installed.

In addition, by forming a projection for sliding contact with the inner wall of the dewatering screen at the upper end of the conveying screw, the width of the opening in the lateral direction of the discharge port is 1/5 to 1/15 of the circumferential length of the dewatering screen, thereby making it possible to It is possible to improve the dewatering capacity of the wastewater and to smoothly discharge the crushed food waste from the outlet. Therefore, the pulverized food waste can be discharged quickly and smoothly from the discharge port to the processing chamber, and the odor caused by the crushed food waste is discharged by evacuating the odor in the process chamber by the first exhaust means, the second exhaust means, or both exhaust means. It is possible to secure a pleasant environment without wandering around.
