Description

  The invention of this application heats and drys garbage, which is waste that contains a relatively large amount of moisture and other waste generated in general households, hospitals, restaurants, fast food stores, convenience stores, etc., using electromagnetic waves such as microwaves. The present invention relates to a garbage disposal device.

  Some garbage processing apparatuses of this type use microwaves for heating garbage, but when the garbage is heated by microwaves, various odor components are generated along with water vapor. A deodorizing apparatus using a heating catalyst is effective for deodorizing such odor components, but conventionally, a dedicated heating source such as a heater is used to heat the catalyst (see, for example, Patent Document 1).

  In addition, there is a type in which a stirring blade is provided in order to uniformly irradiate the garbage with microwaves, and the stirring blade is rotated to stir the garbage (for example, see Patent Document 2).

  However, if the stirring blades are rotated frequently in order to uniformly irradiate the garbage with microwaves, the garbage may become a bowl-like shape or a viscous nodule, which may result in incomplete processing. On the other hand, if the rotation of the stirring blade is stopped, there is a problem of ignition or scorching due to excessive local heating of microwave irradiation.

  As a means for solving such a problem, a technique for evenly irradiating the garbage with microwaves by rotating a container for storing the garbage or further tilting the container is disclosed (for example, (See Patent Document 3).

Japanese Patent Laid-Open No. 7-2301 (FIG. 1) Japanese Patent Laid-Open No. 11-333415 (FIGS. 3 and 4) Japanese Patent No. 2692463 (FIG. 1)

  However, the one described in Patent Document 1 requires a dedicated heater or the like as a heating source for the deodorizing catalyst, which is expensive.

  In addition, as described in Patent Document 2, as described above, when the stirring blades are rotated frequently, the garbage becomes cocoon-like or becomes a nodule with high viscosity, and the processing is incomplete. On the contrary, if the rotation of the stirring blade is stopped, there is a problem such as ignition or scorching due to excessive local heating of microwave irradiation.

  Moreover, in the thing as described in patent document 3, when the weight of the garbage before a process is added to the container which accommodates garbage, it will become a considerable weight, and the motor which is a drive source, and the gear motor which controls rotation speed will be. An expensive torque specification is required. If power transmission is performed using a timing belt, a pulley, or the like, the required power is large and the cost is further increased.

  Accordingly, the present invention has been made to solve such a problem, and provides a garbage disposal device that can be deodorized at low cost by eliminating the need for a dedicated heater for heating the deodorization catalyst. It is the purpose.

  In addition, it is possible to uniformly irradiate the garbage with electromagnetic waves such as microwaves without frequently stirring the garbage in the container using the stirring blades or rotating the container, so that the garbage is in a bowl shape.

  According to the present invention, as the heating source of the catalyst for the deodorizing means, the heating means for heating the garbage in the container by irradiating electromagnetic waves such as microwaves is used together, so a dedicated heater or the like is not required for heating the deodorizing catalyst Thus, a garbage disposal device that can be deodorized at low cost is obtained.

  Further, by disposing the catalyst of the deodorizing means in a part of the container, the odor component in the container can be deodorized without using a waveguide or the like, so that it can be realized at a lower cost.

Thus, the odor component in the exhaust gas can be deodorized more reliably.

  Furthermore, by providing the condensation means for condensing and removing the water vapor in the exhaust gas upstream of the catalyst of the deodorization means, deodorization after moisture removal is performed, so that the deodorization efficiency is improved.

  Moreover, the catalyst heating waveguide of the deodorizing means can be constructed at low cost by branching from the garbage heating waveguide of the heating means.

Is obtained.

  Furthermore, by arranging the stirring means in a position where it does not come into direct contact with the garbage in the container, the stirring means does not come into direct contact with the garbage, so even if the stirring means rotates during the whole garbage drying process, It does not become cocoon-like or form a highly viscous nodule, and it does not ignite or scorch due to local overheating.

  Further, by using the intake air into the container or the exhaust air from the container as a drive source for the agitation means, no special power is required, so that the part cost can be reduced and energy can be saved.

  Alternatively, by using the intake fan into the container or the exhaust fan drive source from the container as the drive source for the stirring means, the stirring means can be rotated with a small torque. The drive source can be realized at low cost without increasing the size.

  Alternatively, even if a motor dedicated to the agitation means is used as the drive source for the agitation means, the agitation means can be rotated with a small torque, so that it can be realized with an inexpensive motor with a small torque.

  In addition, by arranging the stirring means in the vicinity of the irradiation port of electromagnetic waves such as microwaves from the heating means, the degree of coupling with the electromagnetic waves such as microwaves emitted from the heating means is increased, and even with a small stirring means, high radio wave stirring. effective.

  Alternatively, by arranging the stirring means on the container lid side, it can be configured to directly receive and rotate the exhaust air from the container, so that a rotating body (turbine) that rotates with wind power is not required. Further, the cost can be reduced.

  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 is attached to the upper end of the rotary shaft 5 protruding from the center of the bottom surface of the container 1. The cutter blade has a shape in which both sides extend from the rotary shaft 5 toward the side wall inside the container 1 and the tip side is bent upward. 2a, 2a. The rotary blade 2 is disposed so as to intermittently rotate at a high speed in the container 1 along with the intermittent high speed rotation of the rotary shaft 5 supported by the bearing portion 6. 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, 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. Although not shown, a handle 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. Further, 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. 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 so that 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 for generating microwaves is provided in the main body case 13 on the side wall 26 side of the processing chamber 14, and as shown in FIGS. The garbage is heated by irradiating the garbage in the microwave transmission container 1 with the microwave through the microwave transmission cover 30 attached to the microwave irradiation port 29 having the 14 side walls 26 opened. Yes. The cover 30 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.

  On the other hand, an intake fan 31 is provided in the upper part of the main body case 13 on the other side wall 26 side of the processing chamber 14 and is driven to rotate by an intake fan drive motor 32. The intake fan 31 sucks outside air from an intake hole 33 formed in the lower portion of the side wall of the main body case 13 and supplies the outside air into the processing chamber 14 from an air supply hole 34 formed above the side wall 26 of the processing chamber 14. It is.

  An exhaust fan 35 is provided at the lower part of the body case 13 on the other side of the intake fan 31 and is driven to rotate by an exhaust fan drive motor 36. The exhaust fan 35 forcibly exhausts the air in the processing chamber 14 to the outside from an exhaust hole 37 formed in the upper portion of the side wall 26 of the processing chamber 14 through an exhaust port 38 formed in the lower portion of the side wall of the main body case 13. Is.

  Further, a substantially cylindrical duct 39 protruding into the upper surface opening 23 of the processing chamber 14 with the lid 25 closed is formed on the rear surface of the lid 25 as shown in FIG. The duct 39 is formed so that the packing 41 attached to the peripheral edge of the container lid 40 attached to the lower end of the duct 39 is in sliding contact with the upper end of the opening of the container 1 with the lid body 25 closed. This prevents scattering of crushed garbage etc. to the outside of the container 1. Further, the duct 39 is divided into an intake path 43 and an exhaust path 44 by a partition wall 42.

  The intake passage 43 is connected to the above-described air supply hole 34 into the processing chamber 14 and the inside of the container 1 through an intake port 45 formed on one side of the duct 39 and an intake port 46 formed in the container lid 40. Is communicated. The intake passage 43 is provided with fins 48 that change the direction so that the intake air does not flow directly into the exhaust holes 47 formed in the central portion of the container lid 40. The exhaust path 44 connects the exhaust port 37 from the processing chamber 14 and the inside of the container 1 through the exhaust port 49 formed on the other side of the duct 39 and the exhaust hole 47 formed in the container lid 40. Communicate.

  The exhaust path 50 from the exhaust port 37 of the processing chamber 14 to the exhaust fan 35 is provided with an oxidation-reduction deodorization device 52 using a catalyst 51. In general, the working temperature of the catalyst is high and a heater is required for the catalyst. In this embodiment, from the magnetron 27 so that the catalyst 51 can be heated using microwaves as a heat source for heating and drying garbage. The catalyst has a waveguide 28a for heating the catalyst toward the catalyst 51 (see FIGS. 2 and 3). Further, a material that easily absorbs microwaves (carbon C content such as an iron oxide-carbon composite catalyst) is used for the catalyst 51.

  The catalyst heating waveguide 28a is branched from the garbage heating waveguide 28. The catalyst heating waveguide 28a is driven by a motor 53 along the path of the catalyst heating waveguide 28a. A shutter 54 that opens and closes the wave tube 28a is provided. When a control unit (not shown) detects the value of the temperature sensor 55 attached in the vicinity of the catalyst 51, and the temperature of the catalyst 41 rises above the set temperature, the shutter 54 is provided. Is closed, and when the temperature falls below the set temperature, control is performed so that the deodorization is safe and efficient.

  In addition, the deodorization of the exhaust gas containing a large amount of water vapor is inferior in deodorization efficiency because water molecules disturb the arrival of the catalyst 51 overwhelmingly. For this reason, in the present embodiment, the condensation unit 56 that condenses and removes the water vapor in the exhaust gas is disposed on the upstream side of the catalyst 51 in the exhaust path 50, thereby deodorizing after moisture removal. Deodorization efficiency is improved. Since the exhaust generated by heating and drying the garbage is high temperature, the condensation unit 56 condenses the water vapor in the exhaust just by passing outside air through the pipe 58 to which many heat exchange fins 57 are attached. can do. Condensed water droplets are received by a drain pan 59 provided below the aggregating unit 56, stored in a drain tank 61 detachably provided in the main body case 13 through a drain pipe 60, and discarded.

  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 31 and the exhaust fan 35. 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.

  In the middle of the drying operation of the garbage, the amount of heat 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 water in the garbage is vaporized, the heat of vaporization taken away decreases, so that 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 31 and the exhaust fan 35 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.

  During the above-described garbage drying operation, various odor components are generated together with water vapor by heating and drying the microwave, but in this embodiment, the inside of the container 1 is used as a heating source for the catalyst 51 of the deodorizing device 52. Since the magnetron 27 that heats the garbage by irradiating microwaves is used in combination, a dedicated heater or the like is not required for heating the catalyst 27 and can be deodorized at low cost.

  Further, the catalyst 51 is disposed in the exhaust path 50 from the processing chamber 14 where the container 1 is stored and the micro blades from the magnetron 27 are irradiated, and the magnetron 27 is provided with a waveguide 28a for heating the catalyst 51. Thus, it is possible to deodorize the odor components in the exhaust gas more reliably.

  Furthermore, by providing the condensation unit 56 that condenses and removes the water vapor in the exhaust on the upstream side of the catalyst 51, deodorization after water removal is performed, so that the deodorization efficiency is improved.

  Further, the catalyst 51 heating waveguide 28a is branched from the garbage heating waveguide 28 of the magnetron 27, so that it can be constructed at low cost.

  Furthermore, since the temperature sensor 55 for detecting the temperature of the catalyst 51 and the shutter 54 for opening and closing the waveguide 51a for heating the catalyst 51 are provided so that the temperature detected by the temperature sensor 55 becomes the set temperature, Safe and efficient deodorization is possible.

  With this configuration, the catalyst 51 is heated by directly receiving the microwave irradiated from the magnetron 27 into the container 1 without using the waveguide 28a as in the first embodiment. Since the odor component can be deodorized, it can be realized at a lower cost.

  FIG. 5 is a longitudinal sectional view showing a configuration of a main part of a garbage disposal apparatus according to a third embodiment of the present invention. The same reference numerals are used for the same or corresponding parts as those of the above-described embodiment.

  In the present embodiment, the container 1 is housed and the exhaust path of the processing chamber 14 to which the microwave from the magnetron 27 is irradiated, specifically, the container lid 40 is formed at the lower end opening so as to protrude from the back surface of the lid 25. A catalyst 51 is arranged at an exhaust port 49 of an exhaust path 44 in the attached duct 39.

  Also with this configuration, the catalyst 51 is heated by directly receiving the microwave irradiated into the processing chamber 14 from the magnetron 27 without using the waveguide 28a as in the first embodiment. Since it is possible to deodorize the odor component in the exhaust gas from the exhaust gas, it can be realized at a lower cost. Moreover, there is an advantage that the catalyst 51 does not directly contact the garbage.

  FIG. 6 is a longitudinal sectional view showing a configuration of a main part of a garbage disposal apparatus according to a fourth embodiment of the present invention. The same reference numerals are used for the same or corresponding parts as those of the above-described embodiment.

  In this embodiment, the catalyst 51 is placed in the exhaust path of the processing chamber 14 in which the container 1 is accommodated and the micro from the magnetron 27 is irradiated, specifically, the exhaust port 37 a formed in the upper portion of the side wall 26 of the processing chamber 14. Is arranged. Here, since the exhaust port 37a is disposed outside the exhaust port 37a, the exhaust port 37a is provided with a shield (punching plate) 62 that shields the microwave on the downstream side of the catalyst 51 as an opening through which the microwave can pass.

  Also with this configuration, the catalyst 51 is heated by directly receiving the microwave irradiated from the magnetron 27 into the processing chamber 14 without using the waveguide 28a, as described above. Since the odor component in the exhaust can be deodorized, it can be realized at a lower cost. In addition, there is an advantage that the catalyst 1 does not directly contact the garbage.

  FIG. 7 is a longitudinal sectional view showing a configuration of a main part of a garbage disposal apparatus according to a fifth embodiment of the present invention. The same reference numerals are used for the same or corresponding parts as those of the above-described embodiment. In addition, although illustration is abbreviate | omitted after this Example 5, the deodorizing apparatus of the form in any one of the said Examples 1-4 is provided.

  In this embodiment, the container 1 is detachably accommodated in the processing chamber 26 without being driven to rotate. Further, an exhaust hole 47a is formed around the duct 39a in the container lid 40 attached to the lower end opening of the cylindrical duct 39a protruding from the back surface of the lid 25. In addition, air holes 63 and 64 are formed on the upper surface of the main body case 13 in which the outside air intake holes 33 are formed and the corresponding rear surface of the lid body 25 so as to communicate with the lid body 25 in a closed state. Yes. Although not shown in Embodiments 1 to 4, a handle 12 that can be raised and lowered is attached to the top of the container 1.

  In this embodiment, a circular recess 65 is formed in the side wall 26 of the processing chamber 14 facing the microwave irradiation port 29 of the magnetron 27, and microwave irradiation to the garbage is uniformly performed in the recess 65. A stirrer (stirring means) 66 made of a metal such as aluminum for the purpose of stirring the microwaves is mounted for rotation. A rotating shaft 67 of the stirrer 66 is rotatably supported between the side walls of the adjacent exhaust passages 50, and a rotating body (turbine) 68 that rotates by wind power is attached to the rotating shaft 67. In the exhaust path 50, the upstream side of the rotator 68 is partitioned by a partition plate 69, and a cylindrical opening 70 having a reduced diameter is provided so that exhaust air can be blown to the rotator 68 and rotated efficiently. Is formed.

  Therefore, when the exhaust fan 35 is driven, intake and exhaust flows as indicated by arrows, so that the exhaust flowing in the exhaust path 50 is blown to the rotating body 68 of the stirrer 66 and the stirrer 66 rotates. Thereby, the microwave irradiated in the processing chamber 14 from the magnetron 27 is stirred, and the microwave irradiation to the garbage in the container 1 can be performed uniformly.

  As described above, according to the present embodiment, it is possible to uniformly perform microwave irradiation to the garbage without providing the stirring blades for frequently stirring the garbage in the container 1 or rotating the container 1. As a result, it is possible to obtain an inexpensive and highly reliable garbage disposal apparatus without the garbage becoming cocoon-like or having a highly viscous nodule.

An intake fan that forcibly sucks outside air may be provided in the main body case 13 on the side where the magnetron 27 is disposed, and the intake air may be used.

  In addition, since the stirrer 66 does not come into direct contact with the garbage, even if the stirrer 66 is always rotated during the garbage drying process, the garbage does not become cocoon-like or become a viscous nodule. It won't catch fire or scorch due to local overheating.

It is configured to rotate.

  With this configuration, the rotating body 68 as in the fifth and sixth embodiments is not necessary, and the cost can be further reduced. Even if the stirrer 66 is provided on the lid portion side of the processing chamber 14, that is, on the lid body 25 side, substantially the same effect can be obtained.

  FIG. 10 is a longitudinal sectional view showing the configuration of the main part of an eighth embodiment of the garbage disposal apparatus according to the present invention, and the same reference numerals are used for the same or corresponding parts as the previous embodiment.
