Description

  The invention of the present application is a garbage treatment that heats and dries while crushing and stirring garbage that is a waste containing a relatively large amount of water and other waste generated in general households, hospitals, restaurants, fast food stores, convenience stores, etc. It relates to the device.

  In this type of garbage disposal apparatus, a U-shaped fixed blade is provided on the inner wall of a container for storing garbage, a rotary blade is disposed at a position passing between the U-shaped portions of the fixed blade, There is a type that grinds garbage between the rotary blades and heats the garbage by heating with a heater (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 7-116637 (FIG. 1)

  However, in the above case, the garbage is crushed at the position where the fixed blade is provided, but at other positions, the garbage escapes to the space between the rotating blade and the inner wall of the container by the centrifugal force of the rotating blade, As the rotary blade rotates, it rotates along the inner wall of the container, so that there is a problem that the pulverization efficiency is deteriorated.

  In addition, when fibers such as corn peel are entangled with the partially protruding fixed blade, an excessive load is applied to the rotary blade when cutting the fiber entangled with the fixed blade with the rotary blade. It is necessary to enlarge the drive means for rotating the rotary blade.

  Therefore, the applicant of the present application comprises a rotary blade composed of an upper cutter whose both tip sides extend obliquely upward and a lower cutter whose both tip sides extend obliquely downward toward the bottom edge of the container, and the distance between these rotary blades. A plurality of projecting walls that project from the inner wall of the container to guide the garbage to the rotating blade so that the container containing the garbage is rotated and irradiated with microwaves while being pulverized and stirred by the rotating blade A garbage disposal apparatus for drying by heating has already been proposed (Japanese Patent Application No. 2003-120296).

  By the way, in this kind of garbage processing apparatus, it is important that the object to be processed (garbage) in the container is always moving, and drying unevenness is likely to occur in the non-moving part, The size may vary, and in some cases, it may cause burns.

  That is, in the heating and drying treatment step shown in FIG. 5 (the protruding wall of the inner wall of the container is not shown), the garbage R1 stored in the container 1 as shown in FIG. By crushing and stirring with the rotary blade 2 composed of the cutter 3 and the lower cutter 4, it becomes bowl-shaped (b), the volume decreases as the water content decreases (c), and the crushed garbage R2 adheres to the upper inner wall of the container 1 To do. If the drying proceeds as it is, the processing is completed with the adhesion, and it is difficult to take out at the time of disposal. In some cases, only this portion may dry and burn.

  Further, when the drying further proceeds, the garbage becomes a bowl-shaped lump R3 (d), and then is crushed by the rotary blade 2 and gradually subdivided (e). During this crushing, the garbage R4 in the space surrounded by the lower cutter 4 and the bottom of the container 1 is not affected by the garbage placed above without being crushed and agitated, and it is solidified as it is. It is difficult to take out at the time of disposal.

  As described above, the above-described lower cutter 4 is point-symmetric with respect to the rotation axis, and has a shape extending toward the bottom edge of the container 1, and the same portion is pulverized and stirred. The efficiency of crushing / stirring of garbage is not good, drying unevenness occurs, and it becomes difficult to take out even when discarded.

  Moreover, although the upper cutter 3 is provided in order to grind and stir the upper garbage in the container 1, since the grinding garbage R2 adhering to the side wall in the container 1 cannot be removed, it adheres as drying progresses. It will harden and become difficult to dispose of.

  Further, according to various experiments by the present inventors, when a protruding wall is provided on the container side wall corresponding to each cutter blade of the rotary blade, when each cutter blade of the rotary blade and each protruding wall overlap at the same time, It has been clarified that there is a problem that a rotating blade is locked due to a large load when garbage with a high viscosity and a large particle size are sandwiched between them.

  Therefore, the present invention has been made to solve such a problem, the efficiency of crushing and stirring the garbage collected in the lower part of the container can be improved, the occurrence of drying unevenness can be prevented, and at the time of disposal It is another object of the present invention to provide a garbage disposal device that can be easily taken out.

  Furthermore, the upper garbage in the container can be pulverized and agitated, and the crushed garbage adhering to the side wall in the container can be prevented from becoming hard and difficult to take out, and overall efficient heat drying can be performed. An object of the present invention is to provide a garbage disposal device.

  It is another object of the present invention to provide a garbage disposal device that further improves the efficiency of grinding and agitation of garbage while eliminating the lock problem of the rotary blade.

In order to achieve the above object, the present invention provides a container for storing garbage, a rotary blade that is rotatably disposed in a container by a rotating shaft, crushing and stirring the garbage, and a heating means for heating the food waste, as the rotary blade, the cutter blade having a shape extending along the bottom surface of the bearing portion and the container of the rotary shaft from the rotary shaft protruding from the bottom of the container, said rotary shaft is characterized in that it has a cutter blade linearly shape extending obliquely downward from the upper end toward the outer edge of the bottom surface of the container.

Furthermore, as the rotary blade, a lower cutter having each of the cutter blades, and an upper cutter having a cutter blade extending from the rotary shaft toward the side wall in the container and having a shape in which the distal end side extends along the side wall in the container are provided. It is characterized by this.

Further, the protruded from the inner wall of the container so as to have a pre-Symbol rotary blade and spacing garbage comprises a plurality of protruding walls for guiding the rotary blade, the arrangement angle between the rotary blade of the projecting wall relative to the axis of rotation of the rotary blade The arrangement angle of the cutter blade is different.

  Furthermore, the arrangement angle is set to an angle at which the plurality of cutter blades and the protruding wall are not simultaneously positioned in the same direction.

  Further, the number of cutter blades of the rotary blade is different from the number of protruding walls of the inner wall of the container.

  Further, the protruding wall is formed between a height position facing the front end side of the lower cutter and a height position lower than the front end side of the upper cutter along the container side wall.

According to the present invention, a space formed between the cutter blade and the bearing portion or the container bottom surface is formed by a cutter blade having a shape extending from the rotation shaft protruding from the bottom surface of the container along the bearing portion of the rotation shaft and the bottom surface of the container. small and thereby to prevent the ring-shaped mass, the performing the original milling and stirring with a cutter blade linearly shape extending obliquely downward toward the outer edge of the bottom surface of the container from the upper end portion of the rotary shaft Therefore, the efficiency of crushing and stirring the garbage collected in the lower part of the container can be improved, the occurrence of uneven drying can be prevented, and the waste can be easily taken out at the time of disposal.

Furthermore, by having a lower cutter having each cutter blade as described above, and an upper cutter having a cutter blade having a shape extending from the rotation axis toward the side wall in the container and the tip side extending along the side wall in the container, In addition to the above effects, the upper garbage in the container can be crushed and stirred with only the upper cutter, and the pulverized garbage adhering to the side wall in the container can be removed to prevent it from becoming hard and difficult to take out. . In this way, the entire garbage in the container is always moved when the rotary blade is rotated, so that an efficient drying process can be performed as a whole.

  In addition, the container inner wall is provided with a plurality of protruding walls for guiding the garbage to the rotary blade, and by making the arrangement angle of each protruding wall with respect to the rotation axis of the rotary blade different from the arrangement angle of each cutter blade of the rotary blade, The garbage in the container can be guided to the rotating blade by the protruding wall and efficiently crushed and stirred, and the load caused by the rotating blade overlapping with the protruding wall can be reduced. While eliminating, it can improve the efficiency of grinding and stirring of garbage.

  Furthermore, by setting the above-described arrangement angle to an angle at which the plurality of cutter blades and the protruding wall are not simultaneously positioned in the same direction, the plurality of cutter blades and the protruding wall are not simultaneously overlapped in the same direction, which is more effective. In addition, the problem of locking the rotary blade can be solved.

  In addition, by making the number of cutter blades of the rotary blade different from the number of protruding walls of the inner wall of the container, it is only necessary to arrange each cutter blade and each protruding wall at an equiangular pitch, so that the configuration becomes easy.

  Further, the protruding wall is formed between a height position facing the tip end side of the lower cutter and a height position lower than the tip end side of the upper cutter along the container side wall, thereby separating the garbage attached to the side wall by the tip end side of the upper cutter. Without sacrificing the effect, the garbage in the container can be guided to both the lower cutter and the upper cutter, and there is no protruding wall above the upper cutter in the container. Is not much different.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings showing specific examples.

  FIG. 1 is a longitudinal sectional view showing the configuration of the main part of an embodiment of the garbage processing apparatus according to the present invention, FIG. 2 is a longitudinal sectional view of the rotary blade of FIG. FIG. 4 is a longitudinal sectional view showing the state in which the lid is opened and the container is taken out, and the same reference numerals are used for the same or corresponding parts as in FIG.

  The garbage processing apparatus of the present embodiment stores garbage such as straw in a bottomed cylindrical container 1 formed of a heat-resistant microwave transmitting material (resin or the like), and rotates the container 1. At the same time, it is heated and dried by irradiating microwaves while pulverizing and stirring with the rotary blade 2.

  The rotary blade 2 includes an upper cutter 3 and a lower cutter 4, and is attached so as to be orthogonal to the upper end of the rotary shaft 5 protruding from the center of the bottom surface of the container 1. As shown in FIG. 1, the lower cutter 4 has a bearing portion 6 of the rotating shaft 5 on one side from the rotating shaft 5, a cutter blade 4 a extending in a substantially L shape along the bottom surface of the container 1, and the other side And a cutter blade 4b having a shape extending toward the bottom edge of the container 1. Further, as shown in FIG. 2, the upper cutter 3 has a shape in which both sides extend obliquely upward from the rotation shaft 5 toward the side wall in the container 1, and the tip side is bent upward along the side wall in the container 1. Cutter blades 3a and 3a are provided. The rotary blade 2 is disposed so as to intermittently rotate at a high speed in the container 1 as the rotating shaft 5 rotates intermittently at a high speed. An upper coupling 7 for detachably transmitting a driving force of a rotary blade driving motor 20 described later is provided at a lower end penetrating the lower surface side of the container 1 of the rotating shaft 5.

  On the other hand, the container 1 is provided with a plurality of protruding walls 9 that protrude from the inner wall of the container 1 so as to be spaced from the rotating blade 2 and guide the garbage to the rotating blade 2. These protruding walls 9 are formed such that the inner wall side of the container 1 has a wide, substantially triangular horizontal cross-sectional shape.

  In the present embodiment, the arrangement angle of each protruding wall 9 with respect to the rotation axis 5 of the rotary blade 2 is different from the arrangement angle of each cutter blade 3a, 3a, 4a, 4b of the rotary blade 2, and further, these arrangement angles are set. The angle between the plurality of cutter blades 3a, 3a, 4a, 4b and the protruding walls 9 is not set in the same direction at the same time. Specifically, as shown in FIG. 3, by attaching the upper cutter 3 and the lower cutter 4 so as to be orthogonal to each other, the cutter blades 3a, 3a, 4a, 4b are arranged at equal intervals of 90 °. Blades are arranged, and the protruding walls 9 are formed at three positions at equal intervals of 120 ° pitch. Thereby, the several cutter blade 3a, 3a, 4a, 4b and each protrusion wall 9 do not overlap in the same direction simultaneously. That is, only one of the cutter blades 3 a, 3 a, 4 a, 4 b only overlaps with the protruding wall 9 in the same direction.

  Further, the protruding wall 9 is formed between a height position facing the front end side of the lower cutter 4 and a height position lower than the front end side of the upper cutter 3 along the side wall of the container 1.

  On the other hand, on the lower surface side of the container 1, an upper coupling 10 for projecting and detachably transmitting a driving force of a container drive motor 16 described later is formed. A handle 12 that can be raised and lowered is attached to the upper portion of the container 1.

  The container 1 described above is detachably accommodated in a processing chamber 14 having an open top surface provided in the main body case 13. The processing chamber 14 is a metallic microwave shielding chamber that does not transmit microwaves, and a tray 15 on which the container 1 is placed is rotatably provided at the bottom. The tray 15 is connected to a container driving motor 16 provided in the main body case 13 below the processing chamber 14 via a pulley 17 and a belt 18 and is driven to rotate. A lower coupling 19 is formed in the saucer 15, and the upper coupling 10 protruding from the lower surface side of the container 1 is placed on the saucer 15 and engaged with the lower coupling 19. Can be rotated. Furthermore, a lower coupling 22 formed on the output shaft 21 of the rotary blade driving motor 20 provided in the main body case 13 below the processing chamber 14 is rotatably exposed at the center of the tray 15. When the upper coupling 7 formed at the lower end of the rotary shaft 5 of the rotary blade 2 in the container 1 is engaged with the lower coupling 22, the rotary blade 2 can be rotated.

  The upper surface opening 23 of the processing chamber 14 is closed by a microwave shielding lid 25 attached to the upper surface side of the main body case 13 by a hinge 24 so as to be opened and closed. The lid 25 is provided with a handle 26 used when the lid 25 is opened and closed.

  In addition, a magnetron 27 that generates microwaves is provided in the main body case 13 on the side wall 26 side of the processing chamber 14, and is passed through a microwave transmission cover 28 that is attached with the side wall 26 of the processing chamber 14 being opened. The garbage is heated by irradiating the garbage in the container 1 that transmits microwaves with microwaves. The cover 28 is formed of a heat-resistant resin (here, PP resin) that hardly absorbs microwaves, and fine powder generated when the garbage is dried while being crushed by the rotary blade 2 adheres to the magnetron 27. Is preventing.

  An intake fan 29 is provided in the main body case 13 below the magnetron 27 and is driven to rotate by an intake fan drive motor 30. The intake fan 29 sucks outside air from an intake hole 31 formed in a lower portion of the side wall of the main body case 13, and passes through a magnetron 27 to an inside of the process chamber 14 from an air supply hole 32 formed above the side wall 26 of the process chamber 14. To supply outside air. The outside air forcedly sucked by the intake fan 29 passes through the magnetron 27, whereby the magnetron 27 is efficiently cooled.

  An exhaust fan 33 is provided at the lower part on the other side in the main body case 13 and is driven to rotate by an exhaust fan drive motor 34. The exhaust fan 33 forcibly exhausts the air in the processing chamber 14 from the exhaust hole 35 formed in the upper portion of the other side wall 26 of the processing chamber 14 through the exhaust port 36 formed in the lower portion of the side wall of the main body case 13. To do.

  Further, as shown in FIGS. 1 and 2, a substantially cylindrical duct 37 protruding into the upper surface opening 23 of the processing chamber 14 with the lid 25 closed is formed on the back surface of the lid 25. . The duct 37 is formed so that the lower end of the duct 37 enters the inside of the container 1 with the lid body 25 closed, and the opening periphery on the duct 37 side overlaps the opening periphery on the container 1 side. Thus, scattering of crushed garbage etc. to the outside of the container 1 is prevented. The duct 37 is divided into an intake path 39 and an exhaust path 40 by a partition wall 38.

  The intake passage 39 communicates the supply hole 32 for the outside air into the processing chamber 14 and the inside of the container 1 through an intake port 41 formed on one side of the duct 37. Further, the exhaust path 40 communicates the exhaust hole 35 from the processing chamber 14 and the inside of the container 1 through an exhaust hole 42 formed on the other side of the duct 37.

  Therefore, when the exhaust fan 33 is driven, the air in the container 1 passes through the exhaust path 40 of the duct 37, the exhaust hole 42, and the exhaust hole 23 of the processing chamber 14, so that The air is exhausted from the exhaust port 36 to the outside. Further, the outside air sucked from the suction hole 31 at the lower side wall of the main body case 13 by driving the suction fan 29 passes through the magnetron 27 from the suction fan 29 to cool the magnetron 27, and then the air supply holes 32 of the processing chamber 14. The air is supplied into the container 1 through the air inlet 41 and the air intake passage 39 of the duct.

  Further, on the side wall in the processing chamber 14, protrusions 43 are formed at equal intervals in the front, rear, left and right, and the tip of the protrusion 43 extends to a position close to the side wall of the container 1 and rotates. The container 1 is prevented from falling over.

  In the garbage processing apparatus configured as described above, the garbage is put into the container 1, the container 1 into which the garbage is put is stored in the processing chamber 14, the lid 25 is closed, and a power source (not shown) The driving operation is performed by switching on the switch and operating the operation unit.

  In the initial stage of the drying operation of the garbage, the moisture from the garbage is heated by the magnetron 27 while rotating the container 1 by the container driving motor 16 and the intake and exhaust of the air in the container 1 by the intake fan 29 and the exhaust fan 33. As it is removed, the temperature in the container 1 rises. The driving of the rotary blade 2 is controlled by a control unit based on the output of a humidity sensor (not shown), and the rotary blade 2 is driven when the humidity in the container 1 decreases.

  That is, since the microwave generated from the magnetron 27 has a characteristic of being absorbed by moisture, when the rotary blade 2 is driven from the initial stage of the drying operation of the garbage to crush and agitate the garbage, Microwaves are absorbed by the large amount of water accumulated in 1, and the garbage cannot be heated by the microwaves.

  In addition, when the garbage is pulverized and stirred from the beginning of operation, it becomes a paste or becomes a nodule due to viscosity, and the drying efficiency inside the garbage decreases.

  Therefore, in the initial stage of drying operation of garbage, the rotary blade 2 is not driven, and after the humidity sensor detects a decrease in humidity in the container 1, the rotary blade 2 is driven, and the rotary blade 2 is driven to drive the rotary blade 2. When the humidity increases, the driving of the rotary blade 2 is stopped.

  The reason why the container 1 is rotated by the container driving motor 16 is to prevent heating unevenness of the garbage by the magnetron 27 and to heat it uniformly.

  In the middle of the drying operation of the garbage, in order to improve the drying efficiency of the garbage, the rotary blade driving motor 20 is intermittently driven to grind and agitate the garbage. Since a plurality of triangular projecting walls 9 are formed on the inner wall of the container 1, the garbage that tries to rotate along the inner wall of the container 1 by the centrifugal force generated by the rotation of the rotary blade 2 serves as a stopper. It moves in the direction of the center of the container 1 as an inward guide.

  Therefore, since the garbage which moves to the center direction of the container 1 and the rotary blade 2 are always in contact by the protruding wall 9, the garbage is constantly pulverized and stirred by the rotary blade 2, and the pulverization and stirring efficiency is improved.

  Further, as described in Patent Document 1 described above, the garbage is not pulverized between the U-shaped fixed blade and the rotary blade, and the protruding wall 9 is entangled with fibers such as corn husk. Therefore, the garbage can be efficiently pulverized and stirred by guiding the garbage to the rotary blade 2 by the protruding wall 9 without increasing the load on the rotary blade 2 too much.

  In particular, in this embodiment, four cutter blades 3a, 3a, 4a, 4b are arranged at equal intervals of 90 °, and the protruding walls 9 are formed at three locations at equal intervals of 120 °. At the same time, the plurality of cutter blades 3a, 3a, 4a, 4b and the protruding walls 9 do not overlap in the same direction. That is, only one of the cutter blades 3a, 3a, 4a, and 4b overlaps with the protruding wall 9 in the same direction, so the load applied to the rotary blade driving motor 20 is dispersed and a plurality of cutter blades overlap at the same time. Compared to the case, it becomes much harder to lock. Accordingly, it is possible to improve the grinding and stirring efficiency of garbage while more effectively solving the problem of locking of the rotary blade 2. In addition, by changing the number of cutter blades of the rotary blade 2 and the number of protruding walls of the inner wall of the container 1, the cutter blades 3a, 3a, 4a, 4b and the protruding walls 9 may be arranged at equiangular pitches. Configuration becomes easy.

  Further, even when a hard lump is sandwiched between the rotary blade 2 and the protruding wall 9, the protruding wall 9 has a wide triangular shape on the inner wall side, so that the hard lump has a protruding wall along the protruding wall 9. It slides toward the top of 9 and the rotary blade 2 is not restrained.

  And among the lower cutter 4, the space which arises between this cutter blade 4a and the bearing part 6 and the container 1 bottom face is made small by the cutter blade 4a of the shape extended along the bearing part 6 of the rotating shaft 5, and the bottom face of the container 1. In this way, it is possible to prevent the formation of a ring-shaped lump, and the original crushing / stirring can be performed with the cutter blade 4b extending from the rotating shaft 5 toward the bottom edge of the container 1, so that the lower part in the container 1 Improves the efficiency of crushing and stirring the garbage collected in the container, prevents the occurrence of unevenness in drying, and makes it easier to remove it when discarded.

  Further, the upper cutter 3 has a cutter blade 3a that extends obliquely upward from the rotary shaft 5 toward the side wall in the container 1 and has a tip blade that is bent upward along the side wall in the container 1. By crushing and stirring the upper garbage in the container 1 with only the cutter 3, it is possible to prevent the garbage from adhering to the side wall in the container 1 from becoming hard and difficult to take out.

  As described above, the entire garbage in the container 1 is always moved when the rotary blade 2 is rotated, so that the heat drying process can be efficiently performed as a whole.

  Moreover, since the protrusion wall 9 mentioned above is formed between the height position facing the front end side of the lower cutter 4 and the height position lower than the front end side of the upper cutter 3 along the side wall of the container 1, the upper cutter 3 described above. The garbage in the container 1 can be guided to both the lower cutter 4 and the upper cutter 3 without impairing the separation effect of the garbage attached to the side wall by the tip side. Further, since there is no protruding wall 9 above the upper cutter 3 in the container 1, the amount of garbage that can be thrown into the container 1 does not change much.

  In the latter half of the drying operation, the dried and crushed garbage is moved inward by the protruding wall 9, so that the dried crushed garbage is further stirred and crushed uniformly.

  In the middle stage of the above-described drying operation of the garbage, the heating amount from the magnetron 27 and the heat of vaporization taken away when the moisture of the garbage is vaporized balances and the temperature in the container 1 becomes substantially constant. As the drying progresses, the heat of vaporization taken away when the moisture of the garbage is vaporized decreases, so the temperature in the container 1 rises. In the present embodiment, when the temperature in the container 1 rises to 70 degrees Celsius and the temperature sensor detects this temperature, the control unit determines that the drying is finished, and stops the magnetron 27 as the heating means. It has become.

  At this time, the temperature of the dried garbage is high, and if the user accidentally touches the garbage, there is a risk of burns. Therefore, the intake fan 29 and the exhaust fan 33 are continuously driven to lower the temperature in the container 1. And letting the user know that the drying is complete. After the user confirms the notification of the completion of drying, the garbage 25 can be safely discarded by opening the lid 25 and taking out the container 1 as shown in FIG.

  Since the garbage disposal apparatus of the present embodiment is configured as described above, it can be used simply and hygienically, and a garbage disposal apparatus that is excellent in volume reduction rate and is environmentally friendly can be realized.

  In the above embodiment, the upper cutter 3 and the lower cutter 4 are attached so as to be orthogonal to each other, so that four cutter blades 3a, 3a, 4a, 4b are arranged at equal intervals of 90 ° to project. The walls 9 are formed at three positions at equal intervals of 120 ° pitch, but the present invention is not limited to this. For example, the rotary blade 2 has the same configuration as described above, and the projecting walls 9 are formed at two positions at a pitch of 180 °, and the arrangement angle (180 °) of each projecting wall 9 with respect to the rotary shaft 5 of the rotary blade 2 is determined. Only two of the cutter blades 3a, 3a, 4a, 4b are the same as the protruding wall 9 by making the arrangement angle (90 °) of each cutter blade 3a, 3a, 4a, 4b of the rotary blade 2 different. Since they only overlap in the direction, a certain effect can be obtained in solving the lock problem.

  Moreover, in the said Example, since a structure is easy, the number of the protrusion walls 9 is made smaller than the number of the cutter blades 3a, 3a, 4a, 4b, and each cutter blade 3a, 3a, 4a, 4b and each protrusion wall 9 are made. However, the present invention is not limited to this, and the angle pitch may be changed, and the number of protruding walls may be the same as or larger than the number of cutter blades.
