Description
Technical Field
The present invention relates to a food waste disposer, and more particularly, to a food waste disposer which can smoothly decompose waste by microorganisms and prevent problems such as killing of microorganisms due to salts by pulverizing food waste, separating water from solid components of the pulverized food waste, and feeding only the solid components into a microorganism disposer.
Background
Since the landfill of soil or the dumping of ocean into food waste generated from a sink in a kitchen after cooking various foods is prohibited, various methods including processing the recovered food waste by performing garbage measurement to produce fertilizer or feed or using the food waste as energy have been tried by governments and individual control groups in order to reduce the amount of the generated food waste.
It is seen that the throughput of the apparatus normally used for processing food waste has maintained the economy of the apparatus only up to at least tens of tons or more. Therefore, it is a real situation that such a large-sized food processing apparatus cannot be built in the case of a local autonomous group with poor financing.
In view of such a reality, in recent years, in order to reduce the amount of food waste generated in a home or a restaurant, a proposal has been made for disposing of food waste at home or a restaurant by itself. Therefore, as an apparatus for disposing a food waste Disposer directly under a washing tank of a home or restaurant, a food waste shredder (shredder) that is attached under the washing tank and crushes food, a microbial treatment apparatus that treats food with microorganisms, and the like are used.
As an example, korean registered patent publication No. 10-1680129 discloses a "food waste treatment apparatus" as a conventional art, which includes: a food waste crusher for crushing food waste containing water discharged from the water outlet of the washing tank; a microbial processor for decomposing solid components in the pulverized material pulverized by the food waste pulverizer by using microbes; and a crushed material separator provided above the microbial processor, for separating the solid components from the water content in the crushed material to move the solid components to the microbial processor and discharge the water content, and for crushing the food waste and separating the water content from the solid components of the crushed food waste to introduce only the solid components into the microbial processor, thereby smoothly achieving decomposition of the waste by the microorganisms and preventing the microorganisms from being killed by the salt contained in the water.
In particular, in the food waste treatment apparatus proposed in the related art, the crushed material crushed in the food crusher moves through the connection pipe, flows into the crushed material separator through the crushed material inflow portion formed in the upper housing, and the moisture in the crushed material falling into the crushed material separator falls to the lower portion of the filter screen through the filter screen, and is discharged through the moisture discharge port of the lower housing by the moisture discharge pipe.
The solid component dropping from the crushed material inlet is caught by the filter screen, and the rotary blade rotates in the circumferential direction along the upper surface of the filter screen in a state of contacting the upper surface of the filter screen to push and move the solid component caught by the filter screen, so that the solid component drops to the lower portion of the filter screen through the solid component passage opening, and flows into the inside of the processor body of the microbial processor through the solid component discharge opening of the lower casing.
On the other hand, when a part of the solid components flowing in through the pulverized material inflow portion and moving by the rotation of the rotary blade is attached to the lower surface thereof through the mesh-shaped filter net, the cleaning blade rotates in the circumferential direction along the lower surface in a state of being in contact with the lower surface of the filter net, and the solid component sludge remaining on the lower surface of the filter net is pushed down to the lower casing by the contact.
However, in the conventional food waste treatment apparatus proposed in the related art, the lower casing of the ground material separator is formed with a pair of separation walls connected to the side walls from the center of the bottom surface of the lower casing, and the lower casing is separated into a moisture discharge space and a solid content discharge space.
Therefore, the sweeping blade is arranged in a state of being spaced apart from the bottom surface of the lower casing by the height of the separating wall so as not to collide with the pair of separating walls when rotating.
However, since the cleaning blade of the conventional food waste treatment apparatus proposed in the related art rotates in a spaced state without being in close contact with the bottom surface of the lower casing, the solid residue remaining on the lower surface of the filter screen removed by the cleaning blade falls down to the bottom surface of the lower casing, and a part of the falling solid residue does not move to the solid residue discharge port due to the pair of separation walls and accumulates in the moisture discharge space.
Therefore, there are the following problems: the solid residue is accumulated in the lower casing with the lapse of time, and the moisture passing through the filter net cannot be smoothly discharged through the moisture discharge port of the lower casing. In addition, the cleaning blade cannot rotate smoothly to cause a failure, and the moisture discharge port is blocked by solid residue. Moreover, there are the following problems: the offensive odor is generated by the accumulation of the solid contents of the sludge, thereby giving unpleasant feeling to the user.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The food waste treatment apparatus according to the present invention completely decomposes or treats food waste to minimize the generation of food waste by pulverizing a mixture of food waste and wastewater (hereinafter, referred to as "food waste") containing moisture such as water discharged through a drain port of a washing tub by being disposed inside the washing tub, and decomposing the pulverized material with microorganisms. In the description of the food waste treatment apparatus according to the present invention, the "pulverized material" is used as a solid material containing solids and water such as water or wastewater contained therein as a result of being pulverized by the food waste pulverizer (100).
Fig. 1 is a view showing the configuration of a food waste treatment apparatus according to the present invention, fig. 2 is a perspective view of a microbial processor (300) according to the present invention, and fig. 3 is an exploded perspective view of the microbial processor (300) according to the present invention.
Referring to fig. 1, the food waste treatment apparatus according to the present invention includes a food waste pulverizer (100), a microbial processor (300), a connection pipe (500), and a pulverized material separator (400).
A food waste shredder (100) shreds food waste discharged from a drain opening of a washing tub. Then, the pulverized material pulverized by the food waste pulverizer (100) moves to the microbial processor (300) side through the connection pipe (500).
Here, the pulverized material pulverized by the food waste pulverizer (100) as described above has a form including solid components and water, and the configuration of the food waste pulverizer (100) may have various known forms, and a detailed description thereof will be omitted.
The connection pipe (500) has one side connected to the food-trash crusher (100) and the other side connected to the microbial processor (300) to move the crushed material discharged from the food-trash crusher (100) to the microbial processor (300) side. The following are enumerated in the present invention: the connection part of the connection pipe (500) and the food waste crusher (100) is detachably arranged, and the connection part of the connection pipe (500) and the microorganism processor (300) is fixedly connected.
On the other hand, the microbial processor (300) decomposes the pulverized material, which has been moved from the food waste pulverizer (100) through the connecting pipe (500), by microorganisms. Referring to fig. 2 and 3, the microbial processor (300) according to the present invention includes a processor body (320) and an upper cover (330). The processor body (320) and the upper cover (330) are housed inside an outer case (310) that forms the outer shape of the microbial processor (300) of the present invention. The following are enumerated in the present invention: the outer case (310) is assembled by being divided into an upper member (311), a lower member (312), and a front member (313). Here, an example of a specific configuration of the microbial processor (300) according to the present invention will be described below.
As shown in fig. 3, the pulverized material separator (400) is provided above the microbial processor (300). As shown in fig. 1, the pulverized material separator (400) is connected to the connection pipe (500), separates the solid component and the moisture in the pulverized material flowing in through the connection pipe (500), moves the solid component to the microbial processor (300), and discharges the moisture so as not to flow into the microbial processor (300).
Fig. 4 is an exploded perspective view of the morselized material separator (400) according to the present invention, and fig. 5 is a view showing a state in which the morselized material separator (400) according to the present invention is combined with a microbial processor (300). As described with reference to fig. 4 and 5, the pulverized material separator (400) according to the present invention may include a lower housing (460), an upper housing (410), a filter screen (440), and a blade module (430).
The lower housing (460) is disposed at the upper cover (330) of the microbial separator. Here, a moisture discharge port (462) through which moisture in the pulverized material is discharged and a solid content discharge port (461) in the pulverized material are formed in the lower housing (460), and a detailed description thereof will be described below.
A blade module (430) and a filter screen (440) are arranged between the lower casing (460) and the upper casing (410) in this order from above. The filtering net (440) is configured in a net shape through which the water is passed, and is configured with a solid component passing port (441) intercepted in such a manner that the solid component moved by being pushed by the blade module (430) falls down to the microbial processor (300).
The blade module (430) pushes the solid component stuck on the upper portion of the strainer (440) toward the solid component passage port (441) side by rotation in a state of being disposed on the upper portion of the strainer (440), and moves the solid component to the inside of the processor body (320) of the microbial processor (300) through the solid component passage port (441) of the strainer (440) and the solid component discharge port (461) of the lower housing (460).
As explained with reference to fig. 4, the vane module (430) according to the present invention may include a vane rotating shaft portion (431), at least one rotating vane (433), a ring gear (432), and a vane driving portion (434).
The vane rotating shaft (431) is provided inside the pulverized material separator (400) so as to be axially rotatable in the vertical direction. The rotary blade (433) is formed to extend radially back from the blade rotary shaft (431). Here, in the present invention, three rotary blades (433) are provided, but the number is not limited to this.
The rotating blade (433) rotates between the upper housing (410) and the strainer (440) in accordance with the rotation of the blade rotating shaft (431), and pushes and moves the solid component stuck to the strainer (440) toward the solid component passage opening (441) of the strainer (440), so that the solid component passes through the solid component passage opening (441) and the solid component discharge opening (461) of the lower housing (460) and falls into the interior of the microbial processor (300). In the present embodiment, the number of the rotary blades (433) is the same as the number of the cleaning blades (452) to be described below. As shown in fig. 12 and 13, the plurality of rotary blades (433) and the plurality of cleaning blades (452) are closely attached to the filter screen (440), and are vertically arranged to face each other.
In the present embodiment, three rotary blades (433) are arranged in the same number as the number of cleaning blades (452), but the present invention is not limited thereto, and one or more rotary blades (433) may be arranged.
The ring gear (432) has a ring shape for connecting the rotary blade to the radial end. Also, gear teeth are formed in the ring gear (432) in the circumferential direction. Here, the blade driving unit (434) is provided on the outer side in the circumferential direction of the ring gear (432), for example, in the state of the upper cover (330) shown in fig. 3, and engages with the teeth of the ring gear (432) to rotate the ring gear (432), so that the rotary blade (433) can rotate about the blade rotation shaft (431). In the present invention, a pair of blade driving units (434) are disposed with a small capacity, but it is needless to say that one blade driving unit with a large capacity may be provided.
As described above, the upper housing (410) and the filter screen (440) put the blade module (430) therebetween and are combined with the lower housing (460). As shown in fig. 5, a pulverized material inflow portion (420) located above the moisture discharge port (462) of the lower housing (460) is formed in the upper housing (410). The crushed material inflow unit (420) is connected to the connection pipe (500) so that the solid component and the moisture flow in from the connection pipe (500) and flow into the crushed material separator (400).
In addition, a rotary shaft coupling part (415) which rotatably couples the vane rotary shaft part (431) is arranged in the central area of the upper housing (410).
The operation of the pulverized material separator (400) according to the present invention will be described below with the above-described configuration.
First, the pulverized material pulverized by the food waste pulverizer (100) moves through the connection pipe (500) and flows into the pulverized material dispenser through the pulverized material inflow portion (420) formed in the upper housing (410). At this time, the moisture in the pulverized material that has flowed into the pulverized material inflow portion (420) and dropped into the pulverized material separator (400) falls to the lower portion of the filter screen (440) through the filter screen (440), and is discharged through the moisture discharge port (462) formed in the lower housing (460). Here, as described above, the pulverized material inflow portion (420) is formed so as to be positioned on the upper side of the moisture discharge port (462), so that most of the moisture falling down through the pulverized material inflow portion (420) can be directly discharged through the moisture discharge port (462).
The solid component (including a part of water) falling through the crushed material inflow unit (420) is caught by the filter screen (440). At this time, the rotating blade (433) rotated by the driving of the blade driving part (434) rotates in the circumferential direction along the upper surface in a state of being in contact with the upper surface of the filter net (440), thereby pushing and moving the solid component stuck to the filter net (440), and dropping the solid component to the lower part of the filter net (440) through the solid component passing port (441), so that the solid component can flow into the inside of the processor body (320) of the microbial processor (300) through the solid component discharging port (461) of the lower housing (460).
With the above-described configuration, the pulverized material is separated into the solid component and the moisture, and the inflow of the moisture into the inside of the microbial processor (300) is blocked or minimized, whereby the decomposition of the solid component by the microorganisms can be smoothly achieved, and the problems such as the killing of the microorganisms contained in the moisture in the microbial processor (300) by the salts can be solved.
On the other hand, fig. 6 is a view showing a cross section taken along line VI-VI of fig. 5. Referring to fig. 6, the crushed material inflow portion (420) formed in the upper housing (410) may include a crushed material inflow port (422a), a crushed material dropping port (421a), and a drainage trap portion (423).
The crushed material inlet (422a) is connected to the connecting pipe (500) so that the crushed material flowing in through the connecting pipe (500) can flow in. The crushed material dropping port 421a is located above the moisture discharge port 462 with a suspension net interposed therebetween.
In the present invention, as shown in fig. 5 and 6, the following are enumerated: the pulverized material inflow portion (420) is formed by a combination of a lower casing (421) which is formed on the plate surface of the upper casing (410) and is opened upward, and an upper casing (422) which covers the upper portion of the lower casing (421), and in this case, the pulverized material inflow portion (420) is formed in the upper casing (422), and the pulverized material falling portion is formed in the lower casing (421).
The crushed material inlet (422a) and the crushed material drop opening (421a) are communicated with each other through a drainage trap part (423). Here, as shown in fig. 6, a case is exemplified in which the drainage trap part is formed by coupling the upper casing (422) and the lower casing (421), and is formed so as to be inclined downward from the direction of the crushed material dropping port (421a) toward the direction of the crushed material inflow port (422 a).
Therefore, as shown in fig. 6, the drainage trap part 423 is sealed in a state where a part of the crushed material, i.e., moisture and solid components, which flows in through the crushed material inlet 422a remains in the drainage trap part 423, so that it is possible to block odor, bacteria, and the like, which may flow in from the crushed material dispenser or the microbial processor 300 through the crushed material falling port 421a, from flowing out to the outside of the washing tub through the connection pipe 500 and the food waste crusher 100. In addition, since the connection pipe (500) does not need to be formed into a drainage trap structure like a U-shaped trap, the efficiency of the installation space at the lower part of the washing tank can be further improved.
Referring again to FIG. 4, the blade module (430) may include a web sweeping module (450). The screen cleaning module (450) is disposed between the filter screen (440) and the lower housing (460) to clean a lower surface of the filter screen (440) and a bottom surface (461a) of the lower housing (460).
The case where the net cleaning module (450) according to the present invention includes a cleaning rotary shaft (451) and a cleaning blade (452) is described. The cleaning rotation shaft part (451) is axially coupled to the blade rotation shaft part (431) to rotate in synchronization with the rotation of the blade rotation shaft part (431).
A polygonal groove (451a) is formed by recessing the cleaning rotation shaft part (451), and a polygonal shaft (431a) is formed by protruding the blade rotation shaft part (431), and the polygonal shaft (431a) passes through the filter screen (440) and is embedded in the polygonal groove (451a) of the cleaning rotation shaft part (451). Therefore, the cleaning rotation shaft part (451) is axially coupled to the blade rotation shaft part (431), and the cleaning rotation shaft part (451) rotates in synchronization with the rotation of the blade rotation shaft part (431).
Here, the following is shown in the present embodiment: the cleaning rotation shaft section (451) and the blade rotation shaft section (431) are axially coupled by forming a polygonal groove (451a) in a recessed manner in the cleaning rotation shaft section (451) and forming a polygonal shaft (431a) in a protruding manner in the blade rotation shaft section (431), but the cleaning rotation shaft section (451) and the blade rotation shaft section (431) may be axially coupled by forming a polygonal shaft in a protruding manner in the cleaning rotation shaft section (451) and forming a polygonal groove in a recessed manner in the blade rotation shaft section (431).
The cleaning blade (452) extends radially outward from the cleaning rotation shaft (451), rotates with the rotation of the cleaning rotation shaft (451), and comes into contact with the lower surface of the filter screen (440) and the bottom surface (461a) of the lower housing (460) to remove the residue of the solid components remaining on the lower surface of the filter screen (440) and the bottom surface (461a) of the lower housing (460), and the residue is discharged to the microbial processor (300) through the solid component discharge port (461).
Thus, when a part of the solid components flowing in through the crushed material inflow part (420) and moving along with the rotation of the rotating blade (433) is attached to the lower surface thereof through the mesh-shaped filter screen (440), the cleaning blade (452) pushes the solid components to drop by contact, so that the solid components are prevented from being accumulated on the bottom surface (461a) of the lower housing (460), and the moisture passing through the filter screen (440) is smoothly discharged from the moisture discharge pipe (300) through the moisture discharge port (462). In addition, the solid residue is not accumulated on the bottom surface (461a) of the lower casing (460), thereby preventing the blockage caused by the solid residue, reducing the failure of the food garbage disposal device, preventing the generation of foul smell, and being used hygienically and comfortably.
As shown in fig. 12 and 13, the number of cleaning blades (452) is the same as the number of rotating blades (433). The plurality of cleaning blades (452) and the plurality of rotating blades (433) are closely connected to the filter screen (440), and are vertically arranged to face each other.
In the present embodiment, three cleaning blades (452) are arranged in the same number as the number of the rotating blades (433), but the present invention is not limited thereto, and two or more cleaning blades (452) may be arranged.
On the other hand, a pair of adjacent cleaning blades (452) among the plurality of cleaning blades (452) are arranged at intervals along the edge of the cleaning rotation shaft portion (451) in such a manner that the moisture discharge port (462) is disposed therebetween.
Thus, when the pair of cleaning blades (452) stop rotating with the moisture discharge port (462) interposed therebetween, the pair of cleaning blades (452) cover the edge of the moisture discharge port (462) while being in close contact with the bottom surface (461a) of the lower housing (460), and thus, moisture falling through the filter mesh (440) to the vicinity of the edge of the moisture discharge port (462) of the bottom surface (461a) of the lower housing (460) flows into the moisture discharge port (462) along the inclination of the bottom surface (461a) of the lower housing (460) without flowing into the solid component discharge port (461) through the pair of cleaning blades (452).
In addition, the bottom surface (461a) of the lower housing (460) may be formed to be inclined downward toward the moisture discharge port (462) (refer to fig. 9) so that the moisture dropped to the bottom surface (461a) of the lower housing (460) through the filter net (440) may be smoothly discharged through the moisture discharge port (462).
Fig. 7 is a view showing the bottom surface of the upper housing (410) of the pulverized material separator (400) according to the present invention. As explained with reference to fig. 7, at least one stopper rib (412) protruding downward from the inner upper surface and contacting the rotary blade (433) when the rotary blade (433) rotates may be formed in the upper housing (410) of the pulverized material separator (400) of the present invention. Fig. 7 illustrates a case where one stopper rib (412) is formed, but the number thereof is not limited thereto.
Here, as shown in fig. 7, the following is enumerated: the stopper rib (412) is formed from the center of the upper housing (410) in the edge direction, and is formed so as to contact the rotary blade (433) in order from one side to the other side when the rotary blade (433) rotates.
With reference to fig. 8 (a), it can be confirmed that the stopper rib (412) is in contact with the rotary blade (433) at each rotational position in order from the outer side in the rotational axis direction of the rotary blade (433) when the rotary blade (433) rotates. Therefore, when the solid component is pushed and moved along with the rotation of the rotating blade (433), the solid component is attached and accumulated on the rotating blade (433) and attached to the upper side of the rotating blade (433) without falling off, along with the rotation of the rotating blade (433), the upper side of the rotating blade (433) is contacted with the stop rib (412) and inclines, and simultaneously the solid component attached to the upper side of the rotating blade (433) can fall off to the suspension net again.
Fig. 8 (b) shows another embodiment of the stopper rib (412), and illustrates a case where the stopper rib (412) has a curved shape from the center toward the edge in the rotation direction of the rotary blade (433). Thus, the contact interval of the stopper rib (412) and the rotary blade (433) can be proportional to the rotational speed of the rotary blade (433).
Referring again to fig. 2 and 3, the upper member (311) of the outer housing (310) is formed with a first exposure port (314) for exposing the pulverized material inlet (422a) of the pulverized material inlet (420), and a second exposure port (315) for introducing microorganisms.
As shown in fig. 4, a microorganism inlet (411) exposed to the upper part through the second exposure port (315) is formed in the upper housing (410) of the pulverized material separator (400). Here, a solid component passage port (441) of the filter screen (440) and a solid component discharge port (461) of the lower housing (460) are positioned at a lower portion of the microorganism introduction port (411), and when a user introduces microorganisms through the microorganism introduction port (411), the microorganisms can flow into the inside of the processor body (320) through the solid component passage port (441) and the solid component discharge port (461).
Here, as shown in FIG. 3, the microorganism inlet (411) is disposed so as to be openable and closable by an opening/closing member (411a), and thus can be opened and introduced only when microorganisms are introduced, and can be kept in a sealed state at ordinary times. The second exposure port (315) of the upper member (311) may be configured to be opened and closed by an opening and closing cover (316).
The crushed material separator (400) according to the present invention is disposed between the rotating shaft coupling section (415) and the vane rotating shaft section (431), and includes a position sensing section for sensing the rotational positions of the rotating vane (433) and the cleaning vane (452).
The position sensing part (600) includes a mark (610) and a hole sensor (620).
As shown in fig. 4, the mark (610) is disposed in one region of the blade rotation shaft portion (431). Specifically, the cleaning blade is disposed at a position corresponding to the center between the pair of cleaning blades (433).
The hole sensor (620) is disposed on the rotating shaft coupling section (415) and detects the position of a mark (610) disposed on the rotating blade rotating shaft section (431). Specifically, the hole sensor (620) is disposed at a position corresponding to an extension line of the central axis of the moisture discharge port (462). On the other hand, since the rotary blades (433) rotate in synchronization with the cleaning blades (452), when the hole sensor (620) detects the mark (610), the rotational positions of the rotary blades (433) and the cleaning blades (452) are correspondingly sensed.
When the blade module (430) and the net cleaning module (450) do not rotate, the blade module (430) and the net cleaning module (450) are controlled to rotate such that the mark (610) is positioned at a position sensed by the hole sensor (620). Thus, when the hole sensor (620) senses the mark (610), the moisture discharge port (462) is arranged between the pair of cleaning blades (452).
Therefore, as shown in fig. 13, the pair of cleaning blades (452) is placed with the moisture discharge port (462) therebetween, and as the rotation is stopped, the pair of cleaning blades (452) covers the edge of the moisture discharge port (462) while being in close contact with the bottom surface (461a) of the lower housing (460), and thus the moisture dropped to the vicinity of the edge of the moisture discharge port (462) of the bottom surface (461a) of the lower housing (460) through the filter screen (440) flows into the moisture discharge port (462) along the inclination of the bottom surface (461a) of the lower housing (460) without flowing into the solid discharge port (461) through the pair of cleaning blades (452).
Hereinafter, the microbial processor (300) according to the present invention will be described in detail with reference to fig. 3, 5, and 9 to 11.
As described above, the disposer body (320) has an opening opened upward, and a decomposition space is formed inside. The upper cover (330) covers the opening of the upper part of the disposer body (320) in a state that a lower housing (460) of the crushed material separator is arranged.
Here, as shown in FIGS. 3, 5 and 9, the microbial processor (300) according to the present invention may include a moisture drain pipe (340). The moisture drain pipe (340) according to the present invention is provided on one side wall surface of the disposer body (320) in the up-down direction. An upper inlet (341) is formed at the upper part of the moisture drain pipe (340), and a lower drain (342) is disposed at the lower part.
At this time, as shown in fig. 9, the upper inlet (341) of the moisture drain pipe (340) communicates with the moisture outlet (462) formed in the lower casing (460) of the pulverized material separator (400), and the lower outlet (342) of the moisture drain pipe (340) communicates with the decomposition space of the processor main body (320) at the lower part of the processor main body (320). Therefore, the moisture discharged from the pulverized material separator (400) through the moisture discharge port (462) moves to the lower part of the decomposition space of the disposer body (320) through the moisture discharge pipe (340).
A drain pipe connecting part (321) connected to an external drain pipe (not shown) is disposed at the lower part of the disposer body (320), and moisture discharged through the moisture drain pipe (340) is discharged to the outside through the drain pipe connecting part (321).
With the above-described configuration, the moisture separated from the pulverized material separator (400) is discharged to the outside through the moisture drain pipe (340) formed in the side wall of the disposer body (320) and through the lower portion of the disposer body (320), and thus the moisture separated by the pulverized material separator (400) can be discharged to the outside without providing a separate drain pipe.
In addition, water possibly generated in the processor body (320) can be discharged together by discharging water from the crushed material separator (400) through the lower part of the decomposition space of the processor body (320), so that the water generated from the crushed material separator (400) and the microorganism processor (300) can be removed by one water discharge structure.
Here, as shown in fig. 9, the lower drain port 342 of the moisture drain pipe 340 may be positioned above the drain pipe connecting portion 321, and the bottom surface 320a of the disposer body 320 is disposed so as to be inclined from the lower drain port 342 side to the drain pipe connecting portion 321 side, so that smooth water discharge can be performed by the drain pipe connecting portion 321.
On the other hand, a pair of stirring blades (360) is provided inside the microbial processor (300). The stirring blade (360) is rotated by the driving of the stirring driving part (351) to promote the decomposition of the solid component in the decomposition space.
In the present invention, a case is exemplified in which a pair of stirring blades (360) are arranged so as to rotate in mutually opposite directions by rotation of one stirring drive unit (351). As shown in fig. 3 and 5, one stirring drive unit (351) rotates the rotating shaft (361) of either one of the pair of stirring blades (360), and as shown in fig. 9 and 11, the first transmission gear (362) that rotates in accordance with the rotation of the rotating shaft (361) corresponding to the opposite side of the stirring drive unit (351) and the second transmission gear (363) rotate in mesh, and the rotating shaft (364) of the second transmission gear (363) rotates the remaining one of the stirring blades (360), thereby rotating the pair of stirring blades (360) in the mutually opposite directions.
As shown in fig. 9 and 10, a blocking net (370) disposed in a state of being spaced apart from the bottom surface (320a) of the disposer body (320) is provided at a lower portion of the stirring blade (360), so that the solid components can be stirred by the stirring blade (360) in a state of being caught at the blocking net (370).
It is to be understood that although a few embodiments of the present invention have been shown and described, modifications thereof can be made by persons skilled in the art without departing from the spirit or principle of the invention. The scope of the invention is to be determined by the appended claims and their equivalents.
