  In addition, as a place where each branch pipe 31 (the other end of the branch pipe 7) is embedded, for example, a place where trees and plants such as a garden or a field in a house are grown is optimal. For example, it is buried in the ground of a flower bed at a predetermined interval. Moreover, it is preferable to embed each branch pipe 31 in the ground where there are many microorganisms (soil fungi, digestive fungi), so that the garbage injected into the ground can be quickly decomposed into a good environment by the microorganisms. it can.
[0029]
  A reverse odor prevention mechanism 35 is provided in the drain pipe 5 b extending from the disposer 6 to the sewer pipe 4. The reverse odor prevention mechanism 35 is formed with a storage portion 36 in which general waste water is temporarily stored. The general waste water flows through the storage portion 36 and is discharged (discharged) to the sewer pipe 4. Therefore, the general waste water stored in the storage part 36 becomes a water seal, so that malodors do not flow to the disposer 6 side.
[0030]
  As shown in FIG. 2, the crushing chamber 14 and the drainage chamber 16 of the disposer 6 are partitioned by a first punch plate 24 configured by penetrating a large number of through holes in a plate-like plate. The pump chamber 22 is partitioned by a second punch plate 25 configured in the same manner as the first punch plate. The interval between the through holes of the first punch plate 24 or the size of the through holes is generally smaller than that of the second punch plate 25.
[0031]
  The first punch plate 24 guards (blocks) the solid garbage that has been finely cut so that the garbage in the grinding chamber 14 does not flow from the grinding chamber 14 to the drain chamber 16. The punch plate 24 prevents solid garbage from flowing to the sewer pipe 4 side.
  The first punch plate 24 only needs to guard (shut off) the solid garbage that has been finely cut off, and may be a net-like mesh or other ones.
  Thereby, the raw garbage crushed in the crushing chamber 14 passes through the second punch plate 25 and flows only to the pump chamber 22.
[0032]
  As shown in FIG. 3, a backflow prevention valve 33 that prevents clogging of the inlet 32 of each branch pipe 31 (branch pipe 7) is provided at the tip of each branch pipe 31. As shown in FIG. 3A, the backflow prevention valve 33 is composed of a valve body 34 and an expansion / contraction member 35 that moves the valve body 34. The garbage injected by the backflow prevention valve 33 is It does not flow backward to the inlet 32.
[0033]
  The expansion / contraction member 35 is constituted by, for example, a spring or a sealed bellows. The valve body 34 is formed from a spherical or cylindrical synthetic resin or the like. The operation of the backflow prevention valve 33 is as follows. Slurry garbage flows into the branch pipe 31, and when external pressure is applied to the valve body 34 by the garbage, the spring (expandable member 35) contracts and the valve body 34 moves downward. As a result, the outer peripheral surface of the valve body 34 does not block the injection port 32 (the injection port 32 is opened), and garbage is injected (discharged) from the injection port 32 into the ground. It is supposed to be.
[0034]
  Therefore, when slurryed raw garbage is sent to the backflow prevention valve 33, garbage is injected into the ground from the inlet 32 of the branch pipe 31 (branch pipe 7), and when the liquid supply is stopped, The injected garbage or soil is prevented from flowing back to the injection port 32.
[0035]
  The backflow prevention valve 33 may be as shown in FIG. The backflow prevention valve 33 has a valve body 34 (elastic coating) connected to the branch pipe 31 so as to cover the injection port 32 of the branch pipe 31 (branch pipe 7). When the liquid is not liquid, the inlet 32 is closed by the elastic force of the elastic coating, and when the garbage is fed to the branch pipe 31, the pressure of the garbage overcomes the elastic force of the elastic coating and the garbage. Is injected from the inlet 32 into the ground.
[0036]
  Further, the backflow prevention valve 33 may be as shown in FIG. The backflow prevention valve 33 has a cylindrical valve body 34 (elastic coating) provided with an injection port 32a (injection port 32), and a ball plug 34a capable of closing the flow of garbage in the valve body 34 (elastic coating). Is provided. When the garbage is fed to the branch pipe 31, the garbage passes between the valve body 34 (elastic coating) and the ball plug body 34a and is injected from the injection port 32a.
[0037]
  As shown in FIGS. 4 to 6, the first switching valve 30 includes a first cylinder 36, a second cylinder 37 (valve element), and a drive motor 38 that rotates the second cylinder 37. .
  The 1st cylinder 36 is formed in the column shape, and the 2nd cylinder 37 is provided in the inside. A plurality of (about seven) first discharge ports 39 are provided in the circumferential side wall of the first cylindrical body 36 at regular intervals in the circumferential direction, and garbage or the like is introduced into the other side wall. A first introduction port 40 is provided. A branch pipe 7 extending from the disposer 6 to the first switching valve 30 is connected to the first introduction port 40, and a branch pipe 31 is connected to the first discharge port 39.
[0038]
  The second cylindrical body 37 is formed in a cylindrical shape that is concentric with the first cylindrical body 36, is connected to the rotation shaft of the drive motor 38, and extends along the first cylindrical body 36 in the first cylindrical body 36. It rotates or stops at a certain angle in the circumferential direction. A second introduction for introducing garbage or the like into the side wall of the second cylinder 37 facing the portion to which the rotation shaft of the drive motor 38 is connected, at a position corresponding to the first introduction port 40 of the first cylinder 36. A mouth 41 is provided, and garbage in the branch pipe 7 flows into the second cylinder 37 through the first and second inlets 40 and 41. And the 2nd discharge port 42 is provided in one place by the circumferential side wall of the 2nd cylinder 37, and the 2nd drain port 42 moves to the circumferential direction by rotation of the 2nd cylinder 37, and is 1st. When the first discharge port 39 of the cylinder 36 and the second discharge port 42 coincide with each other, the garbage in the second cylinder 37 flows into the branch pipe 31 through the first and second discharge ports 39 and 42. (The first switching valve 30 is in an open state).
[0039]
  If the first discharge port 39 and the second discharge port 42 do not coincide with each other, the garbage in the second cylinder 37 stops in the second cylinder 37 and does not flow into the branch pipe 31. The switching valve 30 is closed.
[0040]
  The drive motor 38 of the first switching valve 30 is electrically connected to the control unit 13 of the disposer 6 and rotates or stops at a constant angle according to the signal of the control unit 13 of the disposer 6.
  Accordingly, the second cylinder 37 is rotated by the drive motor 38, and the second discharge port 42 of the second cylinder 37 is made to coincide with the predetermined first discharge port 39, whereby the garbage is sent to the predetermined branch pipe 31. This makes it possible to change the place where the garbage is injected.
[0041]
  Next, the operation of the garbage processing system 1 in the first embodiment will be described. In the following description, in the garbage disposal system 1 in the initial state (when the garbage disposal system 1 is not operating), the second water stop valve 29 is in the open state, the first water stop valve 21 and the first switching valve 30. Is closed.
  First, when the garbage is not treated, it is in an initial state, and the general waste water drained from the sink 2 flows into the branch pipe 7 and is injected (discharged) into the ground because the first switching valve 30 is closed. And is discharged from the discharge port 17 to the discharge pipe 5b through the crushing chamber 14 and the drainage chamber 16 of the disposer 6 and discharged (discharged) to the sewer pipe 4 and the like.
[0042]
  On the other hand, when processing garbage, solid garbage (residue of meat, fish, grains, etc.) in the garbage bucket inserted in the drain port 3 of the sink 2 is allowed in the grinding chamber 14 of the disposer 6. Input to the extent that the capacity is not exceeded. Then, the solid garbage flows through the drain pipe 5a and flows into the grinding chamber 14 from the introduction port 15 of the disposer 6. When the switch 27 of the sink 2 is turned on, a drive signal S1 is sent to the control unit 13 of the disposer 6, and a close signal S2 is sent from the control unit 13 to the second water stop valve 29. Is closed, and an open signal S3 is sent from the control unit 13 to the first switching valve 30, and the first switching valve 30 is opened (the initial state is released). Then, the drive motor 11 of the disposer 6 rotates, and the rotary cutting plate 10 and the extrusion blade 12 (pump) rotate.
[0043]
  Therefore, when the disposer 6 is driven, that is, when the garbage disposal system 1 is operated, the first and second water stop valves 19 and 29 are closed. 20 does not flow into the grinding chamber 14 of the disposer 6. For this reason, it is possible to prevent a portion of the raw garbage that has been crushed due to the crushing chamber 14 overflowing with the tap water 20 from flowing into the drainage chamber 16. Therefore, during operation of the disposer 6, general waste water (drainage such as hand washing) is prevented from entering the disposer 6.
[0044]
  The solid garbage that has flowed into the pulverization chamber 14 is pulverized by the rotary cutting plate 10 to become a slurry, that is, a mixture containing a liquid substance and a fine solid substance. When the crushed garbage is pulverized more finely than the through hole of the second punch plate 25, the crushed garbage flows into the pump chamber 22 and is discharged by the extrusion blade 12 (pump) in the pump chamber 22. Liquid is fed from the outlet 23 to the branch pipe 7. The garbage sent (discharged) directly from the disposer 6 to the branch pipe 7 reaches the first switching valve 30 and flows into the branch pipe 31 from the predetermined first discharge port 39 of the first switching valve 30. It is injected into the ground from the inlet 32 of the branch pipe 31 (branch pipe 7).
[0045]
  Accordingly, the garbage crushed by the disposer 6 is fed by the extrusion blade 12 (pump), so that it does not flow from the discharge port 17 to the sewer pipe 4 but is fed directly from the discharge port 23 to the branch pipe 7. Then, this garbage is injected into the ground from the injection port 32.
[0046]
  On the other hand, when the garbage in the crushing chamber 14 is reduced and the load applied to the rotating shaft 26 of the drive motor 11 falls below a certain level, an open signal S3 is sent from the control unit 13 of the disposer 6 to the first water stop valve 21. Then, tap water is jetted from the cleaning nozzle 18 to clean the inside of the disposer 6. The washed washing water (mixed liquid of tap water and garbage) is discharged from the inlet 32 of the branch pipe 31 (branch pipe 7) into the ground. When the inside of the disposer 6 is cleaned for a certain period of time, a closing signal S2 is sent from the control unit 13 to the first water stop valve 21, the first water stop valve 21 is closed, and the drive motor 11 is automatically stopped. Then, the cleaning of the disposer 6 and the branch pipe 7 is completed. Thereafter, an opening signal S3 is sent from the control unit 13 to the second water stop valve 29, and a close signal S2 is sent to the first switching valve 30, so that the second water stopping valve 29 is opened and the first switching valve 30 is closed. It is supposed to return to the initial state.
[0047]
  The first switching valve 30 is switched so that the garbage injection location is switched every time the garbage processing system 1 is driven or at a predetermined time (for example, every day). Garbage can be injected into a predetermined place for a predetermined time.
  With the above configuration, the discharge injection means connects one end of the branch pipe 7 to the disposer 6, and feeds the garbage crushed by the disposer 6 from the disposer 6 to the branch pipe 7, and the garbage in the branch pipe 7. Is injected into the ground from the other end of the branch pipe 7, whereby the dust crushed by the disposer 6 can be injected into the ground.
[0048]
  In addition, after the garbage is crushed by the disposer 6, the inside of the disposer 6 is washed by the washing nozzle. Therefore, even if the general waste water is flowed into the disposer 6 after the disposer 6 is driven, the raw waste water is crushed. It does not mix with trash (mixture) and can be discharged into sewer pipes without any problem as general waste water.
  In this way, raw garbage is decomposed into microorganisms that are not harmful to the environment and processed by microorganisms in the ground, so it is good for the environment (for example, outdoor garbage to collect garbage for garbage collection). Since it is no longer placed in the storage area, pollution such as crows is reduced) and the equipment cost is low. Moreover, since raw garbage is inject | poured into the flower bed etc. which are growing trees and plants, this raw garbage can also be utilized as a fertilizer.
[0049]
  Further, the general waste water discharged from the sink 2 is discharged to the sewer pipe 4 through the disposer 6 and the garbage discharged from the sink 2 is pulverized by the disposer 6 and sent directly from the disposer 6 to the branch pipe 7. Since it is liquefied and injected into the ground from the other end of the branch pipe 7, only garbage can be injected into the ground without flowing out into the sewer pipe 4. In other words, only the general waste water can flow into the sewer pipe 4.
[0050]
  Next, a second embodiment of the present invention will be described.
  FIG. 7 shows a second embodiment. This FIG. 7 is a block diagram of the garbage processing system installed in the detached house similarly to 1st Embodiment, for example.

[0052]
  A water supply pipe 19 that communicates from the water pipe 20 to the drain outlet 3 of the sink 2 is provided, and a first water stop valve 21 is provided in the middle of the water supply pipe 19. The sink 2 is provided with a detection sensor 52, and the detection sensor 52 is electrically connected to the control unit 13 of the disposer 6.
[0053]
  The second switching valve 51 is electrically connected to the control unit 13 of the disposer 6, and causes the fluid in the drain pipe 5 to flow to the sewer pipe 4 side or to the branch pipe 7 side by a signal from the control unit 13. Can be done.
[0054]
  In the middle of the branch pipe 7 (between the first switching valve 30 and the second switching valve 51), the crushed garbage in the disposer 6 is sucked into the branch pipe 7 and the raw garbage is taken into the branch pipe 7. A pump 53 for feeding liquid to the injection port 32 is provided. The pump 53 is electrically connected to the control unit 13 of the disposer 6 and is driven or stopped by a signal from the control unit 13.
[0055]
  Next, the operation of the garbage processing system in the second embodiment will be described. In the following description, in the garbage disposal system 1 in an initial state (when the garbage disposal system is not in operation), the first water stop valve 21 is in a closed state, and the second switching valve 51 is fluid in the drain pipe 5. It flows to the sewer pipe 4 side (does not flow into the branch pipe 7), and the first switching valve 30 is in a closed state.
  First, when raw garbage is not treated, it is in an initial state, and the general waste water drained from the sink 2 is drained to the sewer pipe 4 or the like via the grinding chamber 14 of the disposer 6.
[0056]
  On the other hand, when processing garbage, solid garbage is thrown into the drain port 3 of the sink 2 and flows into the crushing chamber 14 of the disposer 6. When the switch 27 of the sink 2 is turned ON, the drive signal S1 is sent to the control unit 13 of the disposer 6, and the switching signal S4 is sent from the control unit 13 to the second switching valve 51, so that the second switching valve 51 is switched. The fluid in the drainage pipe 5 flows to the branch pipe 7 side (does not flow to the sewer pipe 4 side), and an open signal S3 is sent from the control unit 13 to the first switching valve 30, and the first switching valve 30. Is opened (the initial state is canceled). Then, the drive motor 11 of the disposer 6 is rotated by the drive signal S 1, and the garbage is crushed by the rotary cutting plate 10, and at the same time, the drive signal S 1 is sent to the pump 53 to drive the pump 53.
[0057]
  When the pump 53 is driven, the raw garbage pulverized in the pulverization chamber 14 is guided to the branch pipe 7 by the suction force of the pump 53, and the inlet of the branch pipe 31 through the first switching valve 30 from the outlet of the pump 53. The liquid is fed to 32, and garbage is injected into the ground.
  Therefore, the raw garbage crushed by the disposer 6 flows directly from the inside of the disposer 6 to the branch pipe 7, and this raw garbage is injected into the ground through the injection port 32.
[0058]
  On the other hand, when a certain amount of time has passed since the raw garbage started to be crushed, an open signal S3 is sent from the control unit 13 of the disposer 6 to the first water stop valve 21, and tap water flows into the disposer 6 and enters the disposer 6. Is washed. When the inside of the disposer 6 is cleaned for a certain period of time, a closing signal S2 is sent from the control unit 13 to the first water stop valve 21, the first water stop valve 21 is closed, and the disposer 6 and the pump 53 are stopped. The cleaning of the disposer 6 and the branch pipe 7 is completed. Thereafter, a switching signal S4 is sent from the control unit 13 to the second switching valve 51 so that the fluid in the drain pipe 5 flows to the sewer pipe 4 side, and a closing signal S2 is sent to the first switching valve 30 to send the first signal. The switching valve 30 is closed (initial state)
[0059]
  In this garbage disposal system 1 according to the second embodiment, when the disposer 6 is driven, when the hand or the like is put into the sink 2, the detection sensor 52 detects the hand and temporarily disposes the disposer 6. A safety device is provided to stop.
[0060]
  The configuration other than the above is the same as that of the first embodiment.
  The present invention is not limited to the first and second embodiments described above, and can be appropriately changed in design.
  In the first and second embodiments, the disposer 6 is provided with the control unit 13 that controls the garbage disposal system. However, the control unit 13 and the disposer 6 may be configured separately. In the first embodiment, the pump 12 is provided in the disposer 6 to feed the garbage in the disposer 6 to the branch pipe 7. Instead, the second pipe is disposed in the middle of the branch pipe 7. The pump 53 of the embodiment may be provided, and garbage may be injected into the ground by the pump 53.
[0061]
  Furthermore, in the first embodiment, when the disposer 6 is driven, the tap water does not flow into the disposer 6 so that the garbage does not overflow from the crushing chamber 14 and flow into the sewer pipe 4. However, when a stop valve is provided in the middle of the drain pipe 5b extending from the disposer 6 to the sewer pipe 4 and the switching valve 30 is in an open state, the stop valve is closed and the switching valve 30 is also closed. Is closed, the stop valve is controlled to open (the switching valve 30 and the stop valve are opened and closed in reverse), that is, the disposer 6 is driven. In this case, the communication between the sewer pipe 4 and the disposer 6 may be blocked so that the crushed raw garbage does not flow into the sewer pipe 4. In addition, a water stop valve that opens and closes the discharge port 17 of the disposer 6 is provided in the disposer 6, and the disposer 6 is driven by controlling the switching valve 30 and the water stop valve to open and close as described above. In some cases, garbage may be prevented from flowing into the sewer pipe 4.
[0062]
  In the first embodiment, when the disposer 6 is driven, the first and second stop valves 19 and 21 are closed so that tap water does not flow into the disposer 6. The 1, 2 water stop valves 19 and 21 are replaced with water amount adjusting valves and throttling mechanisms, and the amount of water is adjusted so that the pulverizing chamber 14 of the disposer 6 overflows and the garbage does not flow into the drain chamber 16 while the disposer 6 is driven. It may be.
[0063]
【The invention's effect】
  According to the present invention, since the garbage is discharged into the ground, the garbage can be easily used as fertilizer, the equipment cost and the cost of processing the garbage are low, and the environment Even a good garbage disposal system can be provided.
