Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage processing apparatus for processing garbage (garbage) generated in a kitchen by utilizing the decomposition action of microorganisms. 2. Description of the Related Art Garbage generated daily in kitchens such as ordinary households and restaurants, if left unchecked, causes odors due to decay and propagation of pests and insects, thereby deteriorating the sanitary environment of the kitchen. Therefore, it is necessary to quickly and hygienically treat the product. The conventional garbage disposal generally involves installing a drainage basket at a drain of a sink, capturing the garbage supplied together with the wastewater into the drainage basket, appropriately removing the garbage, and disposing of the waste with other waste. It is done by. In European and American countries, a kitchen crusher (disposer) is connected to the drain of the sink, and the operation of the disposer crushes the garbage into the drain, and the drain is connected to the drain with the drain. Garbage disposal methods that are disposed of in wastewater after passing through are widely adopted. [0004] However, in the former method, when taking out the garbage trapped in the drain basket, the odor generated from the spoiled garbage is filled in the kitchen,
In addition, inconveniences such as spillage of spilled water in the sink of the sink occur, and in order to maintain a good sanitary environment in the kitchen, it is necessary to frequently remove and dispose of kitchen garbage. There is a problem that a great deal of labor is required, such as for cleaning. [0005] On the other hand, the latter method is effective for maintaining a sanitary environment because the garbage is treated without stagnation. However, since the garbage is discarded together with wastewater,
2 such as sewer pipe blockage and increased load at sewage treatment plants
This leads to the following inconveniences. Especially in Japan, where sewerage with rainwater is common, natural waters such as rivers, lakes and marshes may be polluted by the overflow of sewage, and eutrophication may occur. The allowable values of suspended solids (SS) and biochemical oxygen demand (BOD) in wastewater to public sewers are strictly regulated, and the wastewater from the disposer, which contains crushed garbage and has a thick liquid state, In fact, the above regulations cannot be satisfied, and the disposal of kitchen waste by a disposer is prohibited. Japanese Patent Application Laid-Open No. 4-156959 discloses that kitchen waste put into a drain of a sink is drained while being conveyed by a screw, and is collected in a kitchen waste bag attached to a discharge end at the end of a transport path. There is disclosed a garbage disposal apparatus configured to automatically seal a bag opening when a predetermined collection amount is reached. However, even when this kitchen waste disposal apparatus is used, the work of taking out and attaching the kitchen waste bag is troublesome, and there is a possibility that the kitchen waste remains in the middle of the transport route and rots. There is a difficulty that cleaning is forced. The applicant of the present application has already proposed a garbage disposal apparatus which can solve the above-mentioned difficulties in garbage disposal. This is to crush the garbage put in the drain of the sink by crushing means connected to the drain, and introduce it into the treatment tank,
This is a device having a simple configuration of mixing with a processing medium stored in the processing tank. The processing medium is a microbial culture base such as wood chips, rice husk, rice bran, and soil. Inside the processing tank containing the processing medium, an environment suitable for propagation of various microorganisms (fungi) is provided. Is formed. Thus, the debris of the kitchen waste introduced into the processing tank and mixed with the processing medium is mixed with water (H2 O) and carbon dioxide (CO2) by microorganisms introduced together with the processing medium and propagated in the processing medium.
). [0008] That is, when this kitchen waste treatment apparatus is used, the user is only required to perform a simple operation of sending kitchen waste to the crushing means connected to the drain port, and drain the water generated as a result of decomposition. By disposing of the waste in a pipe and releasing carbon dioxide gas to the periphery of the treatment tank, the garbage can be completely eliminated, and sanitary garbage disposal can be realized with a small labor burden. [0009] In the above-mentioned kitchen garbage processing apparatus, the garbage introduced into the processing tank gradually decays due to the activity of the microorganisms in an anaerobic environment, and then the microorganisms in an aerobic environment. Follow the process of decomposition into water and carbon dioxide by activity. Therefore, the carbon dioxide gas generated in the processing tank contains a slight putrefaction odor generated by the rotting garbage present inside the processing tank at that time. There is an inconvenience that an unpleasant odor drifts around the treatment tank from which odors are released, giving the user discomfort. [0010] This inconvenience is caused by providing ventilation means inside a sink which is an installation room of a processing tank, and by operating the ventilation means,
The problem can be solved by discharging carbon dioxide gas released around the processing tank into the atmosphere. However, in this case, the installation of the ventilation means and the installation of a communication path for connecting the ventilation means to a predetermined ventilation path are newly required, which leads to a complicated overall configuration and an increase in product cost associated therewith. . The present invention has been made in view of such circumstances, and provides a garbage disposal apparatus capable of preventing the release of carbon dioxide gas generated by decomposition of kitchen garbage with an unpleasant odor into the vicinity of a treatment tank with a simple configuration. The purpose is to: According to the present invention, there is provided a kitchen waste receiving portion formed in a sink of a sink, a drain pipe having one end communicating with the kitchen waste receiving portion and the other end communicating with sewage. A garbage input port formed in the garbage receiving portion, a closing means for opening and closing the garbage input port, a crushing means for crushing the garbage input from the garbage input port, and discharging from a discharge port of the crushing means. A processing tank for receiving the garbage to be processed, and a driving means for driving a mixing means for mixing the processing medium and the garbage stored in the processing tank with one end communicating with the bottom of the processing tank. And the other end is below the bottom of the treatment tank and communicates downstream with the odor control trap of the drainage pipe, and drains water generated in the treatment tank along with the decomposition of kitchen garbage. Providing a pipe, the treatment tank and the crushing means; Are arranged side by side in a substantially horizontal direction. According to the present invention, there is provided a drain pipe which connects the middle of the drain pipe connecting the drain port of the sink to the sewage and the bottom of the processing tank. Water is discharged into the sewage through the drain pipe and the drain pipe. Gas (carbon dioxide) generated inside the treatment tank due to decomposition of kitchen garbage is discharged into the sewage through the drain pipe and the drain pipe, and leaks of odor contained in the gas to the middle of the drain pipe. It is prevented by the odor control trap generally installed. The present invention will be described below in detail with reference to the drawings showing an embodiment. FIG. 1 and FIG. 2 are front cross-sectional views showing an embodiment of a kitchen waste treatment apparatus (hereinafter, referred to as the present invention apparatus) according to the present invention.

A drain pipe 23 is connected to the bottom of the kitchen waste receiving part 22 at a position outside the drain basket 21, and a kitchen waste inlet 24 that opens inside the drain basket 21 is formed substantially at the center. The drain pipe 23 is a pipe extending through the bottom surface of the sink 1 to the outside and connecting this extended end to a sewer (not shown). It is bent in a U-shape and constitutes an odor control trap 25 for blocking odor from the sewer. The upper end of the drainage pipe 23 is always open to the bottom of the garbage receiving portion 22, whereas the garbage inlet 24 is normally airtightly closed by a pusher 26 as shown in FIG. The waste water used for cooking in the sink 2 is first introduced into the drain basket 21 from the drain port 20,
After passing through a number of water holes formed on the peripheral surface of the
The waste A flows into the drainage pipe 23 and is discharged to the sewer through the drainage pipe 23. The garbage A which is put into the drainage port 20 together with the drainage is temporarily stored in the drain basket 21 as shown in FIG. Is done. The apparatus of the present invention is installed inside the sink 1 configured as described above, and a crusher 3 for crushing the garbage A;
A treatment tank 4 for receiving the garbage crushed by the crusher 3
And The crusher 3 is provided with a transfer pipe 30 erected substantially horizontally on a base 5 erected from the inner bottom surface of the sink 1.
And a crushing motor 31 fixed to the base end of the transfer pipe 30, and a transfer screw 32 driven by the crushing motor 31 to rotate around the axis inside the transfer pipe 30.
A receiving port 30a that opens upward is formed on the base end side of the transfer pipe 30. The receiving port 30a is connected to the kitchen waste input port 24 facing the upper portion via a connecting pipe 27. In addition, a plurality of fixed blades
33 is fixed radially, and the transfer screw 32 facing the discharge port 30b is
A rotary blade that rotates while sliding on the fixed blade 33 with the rotation of 32
34 is attached. As shown in the figure, the processing tank 4 is a cylindrical storage container having an opening on the entire surface on one side and reducing the diameter of the other side toward the end. A fine support net 4b made of a material having high rigidity and excellent corrosion resistance, such as stainless steel, resin, etc., is hermetically closed by a cover plate 4a rotatably fitted to the outer edge of the cover 4a. Is stretched. This support net
4b, a pivot 42 is protruded along the axis of the processing tank 4,
The pivot 42 penetrates the cover plate 4a and protrudes to the outside. At the bottom of the sink 1, support legs 6 are provided upright at a suitable distance from the base 5, and the processing tank 4 configured as described above is fitted to the tip side of the transfer pipe 30. Fixed bearing
An end on the reduced diameter side is supported by 40, and the pivot shaft 42 is supported by a bearing 41 fixed on the support leg 6, and is rotatably supported with its axis substantially horizontal. The distal end of the transfer pipe 30 protrudes into the processing tank 4 from the pivotal position by the bearing 40 for a suitable length, and the discharge port 30 b at the distal end of the transfer pipe 30 is opened inside the processing tank 4. The tip of the pivot shaft 42 is connected via a transmission chain 44 to the output end of a mixing motor 43 fixed on the bottom of the sink 1.
It is driven to rotate around the axis in accordance with the rotation of 43. On the other hand, the lid 4a rotatably fitted to the open end of the processing tank 4 is restricted in rotation by the support legs 6 supporting the same side, and follows the rotation of the processing tank 4. It is designed to maintain a fixed state without any problem. In the periphery of the lid plate 4a, an exhaust hole is provided at a position that is the lowest in the fixed state.
The exhaust hole 46 is connected to a middle part of the drain pipe 23, more specifically, a downstream side of the odor prevention trap 25 by a drain pipe 47 fixed outside the corresponding position. Have been. Inside the processing tank 4, a processing medium B is accommodated in a portion closer to the diameter than the supporting net 4b. The treatment medium B is a culture base material that forms an environment suitable for propagation of various microorganisms (fungi), and, for example, a wood strip that has been made porous by a predetermined treatment is used. A plurality of flat plate-shaped stirring blades 45 are inclined on the inner wall of the processing tank 4 at a predetermined angle with respect to the axis and project inward in the radial direction. When the processing tank 4 rotates due to the above, the processing medium B inside the processing tank 4
Is stirred in the axial direction and the circumferential direction. The operation of the apparatus of the present invention constructed as described above is as follows. When a proper amount of garbage A is captured in the drainage basket 21, the pusher 26 is withdrawn and the drainage basket 21 is inserted into the kitchen entrance 24 which opens. The operation is started by turning on an operation switch (not shown) while introducing the kitchen waste A inside. The crushing motor is operated by turning on the operation switch.
31 and the mixing motor 43 are driven, and in the crusher 3,
The transfer screw 32 and the rotary blade 34 at the tip of this rotate,
In the processing tank 4, the processing tank 4 itself rotates around the axis, and the processing medium B contained therein is stirred by the action of the stirring blade 45. The garbage A introduced into the garbage inlet 24 is shown in FIG.
As shown in (2), the crusher 3 reaches the receiving port 30a via the connecting pipe 27, and is transferred toward the tip of the transfer pipe 30 by the rotation of the transfer screw 32 located below the receiving port 30a. At this time, the pusher 26 is used to push the garbage A put into the garbage inlet 24 downward as shown by an arrow in FIG. Garbage A reaching the tip of the transfer screw 32
Is finely crushed by a rotating blade 34 rotating at this tip position and a fixed blade 33 slidably contacting the rotating blade 34, and is introduced into the processing tank 4 through a discharge port 30 b at the tip of the transfer pipe 30. At this time, the processing tank 4 is rotationally driven by the mixing motor 43,
The kitchen waste A introduced into the processing tank 4 is mixed with the processing medium B stirred inside the processing tank 4. The operation of the apparatus of the present invention as described above is performed by turning off the operation switch, which is carried out at an appropriate timing according to the judgment of the user, by the crushing motor 31 and mixing motor
Stop 43 and end. This stop does not occur immediately in response to the OFF operation, but the crushing motor 31 first stops after a predetermined time has elapsed, and the mixing motor 43 stops after the predetermined time has elapsed. The delay time until the crushing motor 31 is stopped is such that the garbage A being transferred reaches the tip of the transfer screw 32 at the time when the turning operation is performed, and the entire amount of the garbage A received by the crushing machine 3 is surely crushed. It is necessary to be discharged to the inside of the processing tank 4. In addition, the delay time until the mixing motor 43 is stopped is determined by rotating the processing tank 4 by a predetermined number after the crusher 3 completes discharging the garbage A, and sufficiently mixing the garbage A and the processing medium B introduced therein. This is necessary in order to disperse the kitchen waste A evenly in the processing tank 4. The processing tank 4 is kept stopped until the next introduction of the kitchen waste A, during which the kitchen waste A is disassembled. The processing medium B stored in the processing tank 4 is, as described above,
It is a microorganism culture base material that forms an environment suitable for the propagation of microorganisms. The crushed pieces of kitchen waste A mixed with the processing medium B are already propagated in various microorganisms (fungi) owned by the processing medium B and the processing medium B. Degraded by microorganisms. In this decomposition, the garbage A is putrefied by the activity of microorganisms in an anaerobic environment, and the rotted garbage A is put into water (H 2) by the activity of microorganisms in an aerobic environment.
O) and the process of decomposing into carbon dioxide (CO2) are performed repeatedly. The aerobic environment is realized by the rotation of the processing tank 4 performed each time the kitchen garbage A is charged, and the air in the upper space of the processing tank 4 is taken into the processing medium B. This is gradually realized by maintaining the processing tank 4 in a stopped state. That is, in the processing medium B inside the processing tank 4, by continuously feeding the garbage A every day, the activity of microorganisms in an anaerobic environment and the activity of microorganisms in an aerobic environment are performed. The garbage A mixed with the processing medium B is completely decomposed into water and carbon dioxide, which are final products, and disappears completely. In addition, in the case of use at home, since the input of the garbage A tends to be irregular, the processing tank 4 is rotated every predetermined time regardless of the presence or absence of the input of the garbage A. It is good to take in air. As described above, inside the treatment tank 4, the putrefaction of the introduced garbage A and the decomposition of the decayed garbage A occur simultaneously and simultaneously, and the decomposition product carbon dioxide is treated at this time. It contains the putrefaction odor emitted by the putrefying garbage A present in the tank 4. On the other hand, the inside of the treatment tank 4 is communicated with the outside by the transfer pipe 30 of the crusher 3 and the drain pipe 47 connected to the exhaust hole 46 on the lower periphery of the cover plate 4a. The kitchen refuse inlet 24 at the end is normally airtightly closed by a pusher 26. Therefore, the carbon dioxide gas generated by the decomposition inside the processing tank 4 is discharged from the exhaust port 46.
Through the drain pipe 47, and is discharged into the drain pipe 23 to which the other end of the drain pipe 47 is connected. As described above, the connection position of the drain pipe 47 is downstream of the odor control trap 25 formed in the middle of the drain pipe 23, and the carbon dioxide gas discharged into the drain pipe 23 is supplied to the sink 2 side. Since the carbon dioxide is released to the sewage without flowing, the unpleasant odor contained in the carbon dioxide gas does not leak to the outside. Further, since the carbon dioxide gas is heavier than the air, it accumulates in the lower part of the processing tank 4 and is effectively discharged from the exhaust hole 46 opened in the lower peripheral edge of the cover plate 4a as described above. Even if the kitchen refuse inlet 24 is opened, there is almost no risk of leakage from this opening. On the other hand, a part of the water generated by the decomposition of the garbage A is taken into the processing medium B, whereby the water content of the processing medium B is adjusted, and an environment suitable for further propagation of microorganisms is obtained. Will be maintained. The remaining portion of the generated water accumulates in the lower portion of the treatment tank 4 and, like the carbon dioxide gas, has an exhaust hole 46.
Then, the water flows into the drain pipe 23 via the drain pipe 47 and is discharged to the sewage. To enable this inflow, drain pipe
Reference numeral 47 denotes an inclined pipe which is slightly downwardly inclined toward the drain pipe 23. In order to prevent the processing medium B inside the processing tank 4 from flowing into the drain pipe 47 together with the generated water, a drain hole 46 is provided. A filter is attached to the opening. In this embodiment, the processing tank 4 is rotated around the horizontal axis, and the garbage A and the processing medium B are mixed by the rotation of the processing tank 4 itself. A rotary processing tank 4 that rotates around the vertical axis may be provided, and the mixing may be performed by rotating the processing tank 4. Alternatively, a fixed processing tank 4 may be provided, and the processing tank 4 rotates in the processing tank 4. The mixing may be performed by a stirring blade, and the present invention is also applicable to these configurations, and the same effect is obtained. The configuration of the crusher 3 is not limited to the configuration shown in the present embodiment. For example, similar to the disposer, the garbage A is rotated by a rotary blade 35 that rotates at a high speed in a horizontal plane facing the garbage input port 24. Crushing and sending it outward in the radial direction,
Crusher 3 of another configuration such as a configuration for discharging into processing tank 4
May be adopted. As described in detail above, the apparatus of the present invention is provided with a drain pipe which communicates the inside of the treatment tank where the garbage is disassembled to the middle of the drain pipe. Is discharged to sewage through a drain pipe and a drain pipe. In addition, gas generated inside the treatment tank due to the decomposition of kitchen garbage is discharged to the sewage through a drain pipe and a drain pipe, and the odor contained in this gas is used to prevent odors generally provided in the middle of the drain pipe. It is not shut off by the trap and does not leak to the outside, and does not give any discomfort to the user due to the unpleasant odor around the processing tank, and this also interposes a drain pipe between the processing tank and the drain pipe. The present invention has excellent effects, such as being realized by such a simple configuration.
