It has become. Further, as shown in FIG. 19, a plurality of drain holes 1 a sized so as not to leak microwaves are provided at the bottom of the processing container 1 so that water can be automatically drained therefrom.

  On the other hand, a rotating blade shaft 9 and a cylindrical stirring shaft 10 are disposed concentrically through the center of the bottom of the processing vessel 1, and the upper end of the rotating blade shaft 9 is as shown in FIG. A rotary blade 11 such as a cutter or a crushing blade is attached, and a stirring blade 12 is attached to the stirring shaft 10 below the rotary blade 11. As shown in FIG. 17, the rotary blade 11 is rotated by a rotary blade motor 13 installed at the lower part in the housing 2, and the stirring blade 12 is rotated by the stirring motor 14 installed at the lower part in the housing 2. Accordingly, the crushing / stirring device 16 is configured.

  As shown in FIG. 19, a discharge port 1b is provided in the vicinity of the drain hole 1a at the lower portion of the peripheral wall of the processing container 1, and the discharge port 1b is treated as shown in FIGS. It is opened and closed by a discharge door 17 pivotally attached to the outer peripheral wall of the container 1, and the discharge door 17 can be switched between a locked state and an unlocked state by operating a lock lever 18.

  In the conventional garbage processing machine as described above, after the garbage is put into the processing container 1 and the microwave shielding upper lid 3 is closed, when a start button of a touch operation panel (not shown) is pressed, the rotary blade motor The rotation of the rotary blade 11 and the stirring motor 14 by 13 is driven, the microwave irradiation by the magnetron 5 and the blowing by the blower fan 15 are performed, and the garbage is stirred by the rotating stirring blade 12.

Japanese Patent Laid-Open No. 2002-370079

  However, in the conventional garbage processing machine, as described above, when the exhaust temperature of the blast exhausted from the processing container 1 reaches a predetermined temperature, it is predicted that the drying process of the garbage is finished, and the garbage drying machine However, since the humidity in the atmosphere varies greatly over the course of the year, and changes greatly depending on the season, weather, etc., even if one day is seen, the exhaust temperature changes due to this change in outside air humidity. Therefore, it is impossible to accurately determine the end of the garbage drying process. Therefore, the garbage drying process cannot be completed at a suitable timing to stop the operation of the garbage processing machine. Cases arise. For this reason, the garbage processing machine continues to operate despite the completion of the drying process, resulting in a problem that the processing time is unnecessarily extended and power is wasted. If the garbage processing machine is stopped even though it has not been completed, it becomes necessary to drive the garbage processing machine again to finish drying, which is very troublesome and increases the time required for the drying process. is there.

  The present invention has been made in view of such circumstances, so that even if the outside air humidity changes, the garbage can be efficiently dried, and the drying process can be terminated at a suitable timing.

It is a control apparatus of the garbage processing machine as described in above.

  The invention according to claim 7 is the control apparatus for a garbage disposal according to claim 5 or 6, wherein the irradiation energy of the magnetron is controlled by the amount of electric power supplied to the magnetron.

  The invention according to claim 9 is characterized in that the amount of air blown by the blower fan is controlled by the amount of electric power supplied to the blower fan. is there.

  The invention according to claim 10 is provided with a plurality of the blower fans, and the amount of blown air is controlled by ON / OFF operation of the blower fan. It is a control device.

  In the present invention, when the outside air humidity taken into the processing container changes, at least one of the irradiation energy and the blowing amount is adjusted so that the moisture movement inside the garbage and the evaporation amount from the garbage surface by blowing are balanced. Since the constant-rate drying period is always maintained, the exhaust temperature suddenly changes after the constant-rate drying period is clarified, so that the end of the drying can be surely confirmed. Using this as an index, the garbage dryer can be stopped at the optimal timing.

  Here, when the outside air humidity is low, evaporation from the surface of the garbage is likely to be performed by blowing air, so that the moisture movement inside the garbage does not keep up with the amount of evaporation from the surface of the garbage, and for this reason, the steam ratio Since the low blast is heated by microwaves and the exhaust temperature rises, the constant rate drying period may not be maintained. At this time, by performing at least one of increasing irradiation energy and decreasing blast volume, A constant rate drying period can be stably maintained by balancing the amount of evaporation from the surface and the movement of moisture inside the garbage. On the other hand, when the outside air humidity is high, it is difficult to remove the moisture from the surface of the garbage, and for this reason, the amount of moisture evaporation from the surface of the garbage is insufficient for the movement of moisture inside the garbage, so the constant rate drying period However, at this time, by reducing at least one of the irradiation energy and increasing the air flow rate, the moisture movement inside the garbage and the evaporation amount from the garbage surface due to the air flow are balanced. Thus, the constant rate drying period can be stably maintained.

  Therefore, as described above, the balance between the movement of moisture inside the garbage and the amount of evaporation from the surface of the garbage caused by blowing air allows the garbage to be dried with the optimum irradiation energy without waste, thus reducing power consumption. Furthermore, there is an effect that the garbage can be efficiently dried in the shortest time according to the outside air humidity.

  Furthermore, since the garbage processing machine can be automatically operated according to changes in the outside air humidity, there is an effect that the operation is simplified and versatility is enhanced.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  The present inventors conducted a test and found that a change in the outside air humidity greatly affects the drying of the garbage when the garbage is heated and dried by the garbage processor.

  In FIG. 1, 50 indicates an example of an average value of the outside air humidity examined over one year (12 months), 51 indicates the maximum humidity and 52 indicates the minimum humidity. On the other hand, reference numeral 50 in FIG. 2 shows an example in which a change in outside air humidity in one day (24 hours) was examined. As is clear from FIGS. 1 and 2, it can be seen that the outside air humidity 50 varies greatly throughout the year and even within one day.

  On the other hand, FIG. 3 shows that in the conventional garbage processing machine shown in FIGS. 16 to 18, the irradiation energy by the magnetron 5, the amount of air blown by the blower fan 15, and the rotational speed of the crushing / stirring device 16 are adjusted to predetermined values. This shows a case where a stable drying process is performed. That is, according to FIG. 3, when the garbage disposal machine is started, the exhaust humidity Ho decreases as the exhaust temperature To increases, and then the exhaust temperature To and the exhaust humidity Ho are held substantially constant. A constant rate drying period occurs. At this time, the fact that there is no change in the exhaust gas temperature To even though the irradiation energy is constant means that the irradiation energy is not used for sensible heat, and all is used for latent heat (moisture evaporation). As shown in FIG. 4, this is a balance between the movement of moisture inside the garbage generated by heating the garbage with microwave irradiation energy and the amount of evaporation by which moisture is removed from the surface of the garbage by blowing. It is thought that it was in the state.

  After the constant rate drying period in FIG. 3, the exhaust gas temperature To suddenly increases. This is used to heat the moisture whose evaporation energy has evaporated by sensible heat because the residual moisture in the garbage is reduced after the constant rate drying period and the amount of evaporation of the water decreases rapidly. Therefore, it is considered that the exhaust temperature To rises rapidly.

  Therefore, utilizing the fact that the exhaust temperature To rises rapidly after the constant rate drying period, the end of drying is determined when the exhaust temperature To in the constant rate drying period has increased by the specified value 53, and this determination determines the garbage disposal. The machine can be stopped. If a stable constant rate drying period is maintained in this way, it is possible to accurately determine the end of drying and stop the operation of the garbage disposal machine at a suitable timing.

  However, as shown in FIG. 1, the outside air humidity 50 changes greatly throughout the year, and as shown in FIG.

  That is, FIG. 3 shows that, for example, when the outside air humidity 50 is relatively high, the irradiation energy by the magnetron 5 and the amount of air blown by the blower fan 15 and the rotation speed of the crushing / stirring device 16 are adjusted, thereby drying at a constant rate 5 shows a case where the period is maintained. When the garbage processing machine adjusted when the outside air humidity 50 is high is used when the outside air humidity 50 is low, a stable constant rate drying period is obtained as shown in FIG. It has been found that the exhaust gas temperature To changes in an unstable manner without being able to hold.

  This is because the lowering of the detected outside air humidity Hi increases the action of removing moisture from the garbage surface by blowing air. For this reason, as shown in FIG. Moisture movement inside the garbage is not in time. For this reason, only the dust surface is dried, and therefore the exhaust air temperature To gradually rises when the air blown with a small steam ratio is heated by the sensible heat of the irradiation energy, and for this reason, the constant rate drying is performed. It is thought that the period will not be retained. Thus, if the constant rate drying period is not maintained, the end of drying cannot be determined.

  FIG. 7 shows an example of an embodiment of the present invention for reliably maintaining a constant rate drying period and enabling stable operation even when the outside humidity 50 changes as described above. 16 to 18 denote the same components, and the basic configuration is the same as that of the conventional one shown in FIGS. 16 to 18.

  As shown in FIG. 7, an outside air hygrometer 54 for detecting the outside air humidity Hi of the outside air taken into the processing container 1 from the air intake 6a in the garbage processing machine is provided, and the air in the processing container 1 is sent from the exhaust port 7a to the outside. An exhaust thermometer 55 for detecting the exhaust temperature To of the exhaust discharged is provided. Here, FIG. 7 shows a case where one magnetron 5 and one blower fan 15 are provided, but the number of magnetrons 5 and blower fans 15 is not limited, and will be described later. As shown in FIG. 13, two or more plural pieces may be provided.

  On the other hand, FIG. 8 shows an example of a controller for controlling the garbage processing machine. The controller 56 receives an activation command 57 from a touch operation panel or the like (not shown). When the start command 57 is input, the controller 56 outputs an operation start signal 58 to the magnetron 5 and the blower fan 15 and the crushing / stirring device 16 shown in FIG.

  The controller 56 also includes an outside air humidity Hi from the outside air hygrometer 54, a reference humidity 59 of the outside air humidity Hi, an exhaust gas temperature To from the exhaust gas thermometer 55, and a specified value 53 of the exhaust gas temperature To. Is entered.

  The controller 56 drives the power control signal 60 for controlling the amount of power (for example, current value) for driving the magnetron 5 or the blower fan 15 based on the outside air humidity Hi from the outside air hygrometer 54. One or both of the power control signals 61 for controlling the amount of power (for example, current value) to be output are output.

  The controller 56 determines the end of drying when the exhaust temperature To from the exhaust thermometer 55 has increased by a specified value 53 with respect to the temperature during the constant rate drying period, and is determined to have ended drying. Then, the operation stop signal 62 is output to the magnetron 5, the blower fan 15, the crushing / stirring device 16 and the like shown in FIG. 7 to stop the operation of the garbage processing machine.

  Next, the control method of the garbage processing machine of this invention by the apparatus of FIG. 7, FIG. 8 is demonstrated.

  First, as shown in FIG. 2, a reference humidity 59 is set for an outside air humidity 50 that varies. The reference humidity 59 can be arbitrarily set, and can be set to an intermediate temperature between the highest humidity and the lowest humidity in one day, for example. In FIG. 2, the reference humidity 59 is 70%, which is an intermediate point between the maximum humidity 100% and the minimum humidity 40%.

  The first control method of the present invention is performed as follows.

  This first control method is based on the irradiation energy by the microwave of the magnetron 5 and the rotation of the blower fan 15 so that when the outside air humidity 50 of FIG. This is a case where the air flow rate is adjusted. Then, the power amount (current) of the magnetron 5 at this time is set as a heating power value 63 as shown in FIG. 9A, and the power amount (current) of the blower fan 15 is set as a blown power value 64 as shown in FIG. 9B. Set as follows. At this time, the crushing / stirring device 16 is always driven at a constant rotational speed.

  When garbage is put into the processing container 1 of FIG. 7 and a touch operation panel or the like (not shown) is operated to input a start command 57 to the controller 56 of FIG. 8, the controller 56 causes the magnetron 5 and the blower fan 15 to be crushed. The operation start signal 58 is output to the agitator 16 and the like to start each, and the garbage drying process is started.

  At this time, the irradiation energy by the magnetron 5 and the amount of air blown by the blower fan 15 are adjusted in advance with reference to the time when the outside air humidity 50 is high so that a constant rate drying period with a constant exhaust gas temperature To occurs, as shown in FIG. Drying is performed while the constant rate drying period is maintained. Accordingly, the exhaust temperature To from the exhaust thermometer 55 rises by the specified value 53 after the end of the constant rate drying period, so that the controller 56 can accurately determine the end of drying, and therefore the operation stop signal 62 is generated. The garbage processing machine can be stopped at a suitable timing by outputting to the magnetron 5, the blower fan 15, and the crushing / stirring device 16.

  On the other hand, when the garbage disposal is performed by the garbage disposal machine when the outside humidity 50 is lower than the reference humidity 59 in FIG. 2, the following control is automatically performed.

  That is, since the outside air humidity Hi detected by the outside air hygrometer 54 is always input to the controller 56, the controller 56 detects that the outside air humidity 50 has dropped below the reference humidity 59 in FIG. The controller 56 outputs the power control signal 60 to the magnetron 5, or outputs the power control signal 61 to the blower fan 15, or both, thereby increasing at least one of the increase in the irradiation energy or the decrease in the blown amount. Control.

  That is, when the outside air humidity 50 is lowered, as shown in FIG. 6, the action of removing moisture from the surface of the garbage by blowing is increased. For this reason, the moisture inside the garbage with respect to the amount of evaporation from the surface of the garbage The movement will not be in time.

  For this reason, as shown to Fig.9 (a), it operates by the electric power value which raised the heating electric power value 63 of the magnetron 5 only by the predetermined width 63a. As a result, the moisture movement inside the garbage is enhanced, and the moisture movement inside the garbage and the amount of evaporation removed from the garbage surface by blowing are balanced and the constant rate drying period is maintained. In addition, the magnitude | size of the predetermined width | variety 63a which raises the said heating electric power value 63 is previously calculated | required by a test. When the detected outside air humidity Hi returns to the reference humidity 59 or higher, the magnetron 5 is operated again at the heating power value 63.

  Further, instead of the method of increasing the heating power value 63 as shown in FIG. 9A, as shown in FIG. 9B, the operation is performed with the power value obtained by reducing the blowing power value 64 of the blowing fan 15 by a predetermined width 64a. You may make it do. In this case, the amount of evaporation removed from the surface of the garbage by blowing is reduced, so that the amount of moisture evaporated from the surface of the garbage and the movement of moisture inside the garbage are balanced and a constant rate drying period is maintained. It becomes like this. In addition, the magnitude | size of the predetermined width | variety 64a which reduces the said blast power value 64 is previously calculated | required by a test. When the detected outside air humidity Hi returns to the reference humidity 59 or higher, the blower fan 15 is operated again at the blown power value 64.

  Further, as described above, one of the heating power value 63 and the blowing power value 64 may be controlled, but the constant rate drying period is similarly adjusted by adjusting both the heating power value 63 and the blowing power value 64 at the same time. The predetermined widths 63a and 64a to be adjusted in this case are small values.

  Next, the second control method of the present invention will be described.

  In this control method, when the outside air humidity 50 in FIG. 3 is lower than the reference humidity 59, the irradiation energy by the microwaves of the magnetron 5 and the blown air amount by the rotation of the blower fan 15 are set so that a constant rate drying period with a constant exhaust gas temperature To occurs. This is the case when adjusting. The electric energy (current) of the magnetron 5 at this time is set as the heating electric power value 65 as shown in FIG. 10A, and the electric energy (current) of the blower fan 15 is set as the blowing electric power value 66 as shown in FIG. 10B. Set to.

  When the garbage processing machine is operated, the irradiation energy from the magnetron 5 and the amount of air blown by the blower fan 15 are adjusted in advance with reference to the time when the outside air humidity 50 is low so that a constant rate drying period with a constant exhaust temperature To occurs. As shown in FIG. 3, drying is performed in a state where the constant rate drying period is maintained. Therefore, the exhaust temperature To from the exhaust thermometer 55 rises by the specified value 53 after the end of the constant rate drying period, thereby accurately determining the end of drying and stopping the garbage processing machine at a suitable timing. it can.

  When the outside air humidity 50 becomes higher than the reference humidity 59 in FIG. 2, the controller 56 outputs a power control signal 60 to the magnetron 5, and as shown in FIG. 10 (a), the heating power value 65 of the magnetron 5 is predetermined. The operation is performed with the power value decreased by the width 65a. This suppresses moisture movement inside the garbage so that the amount of evaporation from the garbage surface decreases due to the high detected outside air humidity Hi, thereby maintaining a constant rate drying period. .

  Further, instead of the method of reducing the heating power value 65 as shown in FIG. 10A, when the outside air humidity 50 becomes higher than the reference humidity 59, the controller 56 outputs a power control signal 61 to the blower fan 15, As shown in FIG. 10B, the operation may be performed with a power value obtained by increasing the blowing power value 66 of the blowing fan 15 by a predetermined width 66a. As a result, the air volume is increased by the amount by which the amount of evaporation from the garbage surface is reduced due to the high detected outside air humidity Hi, thereby balancing the movement of moisture inside the garbage and the amount of evaporation from the surface of the garbage. As a result, the constant rate drying period is maintained.

  Further, as described above, one of the heating power value 65 and the blowing power value 66 may be controlled. However, by adjusting both the heating power value 65 and the blowing power value 66 at the same time, the constant rate drying is similarly performed. The period can be held, and the predetermined widths 63a and 64a to be adjusted in this case are small values.

  Next, the third control method of the present invention will be described.

  First, as shown in FIG. 11, a reference humidity width 67 is set for the changing outside humidity 50. The reference humidity range 67 can be arbitrarily set. In FIG. 11, the reference humidity range 67 is 60% to 80% between the maximum humidity and the minimum humidity of the day. Instead of the reference humidity 59, it is input to the controller 56 of FIG.

  In this control method, when the outside air humidity 50 in FIG. 11 is within the reference humidity range 67, the irradiation energy of the magnetron 5 by the microwave and the blower fan 15 so that a constant rate drying period with a constant exhaust temperature To in FIG. 3 occurs. Adjust the amount of air blown by rotation. Then, the electric energy (current) of the magnetron 5 at this time is set as the heating electric power value 68 as shown in FIG. 13A, and the electric energy (current) of the blower fan 15 is set as the blowing electric power value 69 as shown in FIG. Set as follows.

  When the garbage drying process is started, the irradiation energy by the magnetron 5 and the amount of air blown by the blower fan 15 are adjusted in advance so that a constant rate drying period with a constant exhaust gas temperature To occurs, so that the outside air humidity 50 shown in FIG. In a state of operating within the reference humidity range 67, drying with a constant rate drying period is performed. Accordingly, the exhaust temperature To from the exhaust thermometer 55 rises by the specified value 53 after the end of the constant rate drying period, so that the controller 56 can accurately determine the end of drying, and therefore the operation stop signal 62 is generated. The garbage processing machine can be stopped at a suitable timing by outputting to the magnetron 5, the blower fan 15, and the crushing / stirring device 16.

  On the other hand, when the detected outside air humidity Hi becomes lower than the lower limit value (60%) of the reference humidity range 67 in FIG. 11, or the outside air humidity Hi becomes higher than the upper limit value (80%) of the reference humidity range 67 in FIG. At that time, the controller 56 outputs the power control signal 60 to the magnetron 5 to adjust the heating power value 68 of FIG. 13A, or outputs the power control signal 61 to the blower fan 15 to output FIG. ) Is adjusted, or both are performed to control at least one of an increase in irradiation energy and a decrease in the amount of blown air.

  First, the case where the heating power value 68 of the magnetron 5 in FIG. 13A is adjusted will be described. When the outside air humidity 50 in FIG. 2 becomes lower than the lower limit value (60%) of the reference humidity width 67, the surface of the garbage by blowing. Since the moisture removing action from the garbage is increased and the moisture movement in the garbage is not in time for the amount of evaporation from the garbage surface, the heating power value 68 in FIG. 13A is increased by a predetermined width 68a. drive. As a result, the moisture movement inside the garbage is enhanced, so that the moisture movement inside the garbage and the amount of evaporation removed from the garbage surface by blowing are balanced and the constant rate drying period is maintained. When the detected outside air humidity Hi returns to the reference humidity range 67, the magnetron 5 is again operated at the heating power value 68.

  Further, when the outside air humidity 50 becomes higher than the upper limit value (80%) of the reference humidity width 67, the action of removing moisture from the surface of the garbage by blowing is reduced and it becomes unsuitable for the moisture movement inside the garbage. The heating power value 68 of (a) is operated at a power value that is reduced by a predetermined width 68b. As a result, the evaporation amount by blowing air is balanced with the moisture movement inside the garbage, so that the constant rate drying period is maintained. When the detected outside air humidity Hi returns to the reference humidity range 67, the blower fan 15 is operated again with the blown power value 69.

  Further, the case of adjusting the blowing power value 69 of the blowing fan 15 in FIG. 13B will be described. When the outside air humidity 50 in FIG. 2 becomes lower than the lower limit value (60%) of the reference humidity width 67, the garbage generated by blowing air. Since the moisture removal action from the surface is enhanced and the movement of moisture inside the garbage cannot keep up with the amount of evaporation from the garbage surface, the power value obtained by reducing the blowing power value 69 of FIG. 13B by a predetermined width 69a. Drive on. As a result, the movement of moisture inside the garbage and the amount of evaporation removed from the surface of the garbage are balanced, and the constant rate drying period is maintained. When the detected outside air humidity Hi returns to the reference humidity range 67, the blower fan 15 is operated again with the blown power value 69.

  Further, when the outside air humidity 50 becomes higher than the upper limit value (80%) of the reference humidity width 67, the action of removing moisture from the surface of the garbage by blowing is reduced and it becomes unsuitable for the moisture movement inside the garbage. The operation is performed at a power value obtained by increasing the blowing power value 69 of (b) by a predetermined width 69b. As a result, the evaporation amount by blowing air is balanced with the moisture movement inside the garbage, so that the constant rate drying period is maintained. When the detected outside air humidity Hi returns to the reference humidity range 67, the blower fan 15 is operated again with the blown power value 69.

  Further, as described above, only one of the heating power value 68 and the blowing power value 69 may be controlled, but the constant rate drying can be performed by adjusting both the heating power value 68 and the blowing power value 69 at the same time. The predetermined widths 68a, 68b, 69a, 69b to be adjusted in this case are small values.

  14 and 15 show another embodiment of the present invention, which shows a case where a plurality of magnetrons 5 and blower fans 15 are provided, respectively. In the embodiments of FIGS. Although the case where the power values of the magnetron 5 and the blower fan 15 are controlled by 61 has been described, in this embodiment, the number of operating units of each of the magnetron 5 and the blower fan 15 is controlled by the ON / OFF signals 70 and 71. The control method is exactly the same as in the above embodiment. In the form of FIGS. 14 and 15, the number of operating magnetrons 5 and the blower fans 15 is switched, so that the control becomes easy.

  As described in each of the above embodiments, when the outside air humidity Hi taken into the processing container 1 changes, the irradiation energy and the irradiation energy are adjusted so that the movement of moisture inside the garbage and the amount of evaporation from the garbage surface by blowing are balanced. Since the constant rate drying period is always maintained by adjusting at least one of the blast volumes, it is clear that the exhaust temperature To suddenly increases after the constant rate drying period ends, so that the end of the drying can be surely known. Therefore, the garbage processing machine can be stopped at an optimal timing using the increase in the exhaust gas temperature To as an index.

  Therefore, since the garbage can be dried with the optimum irradiation energy without waste, the power consumption can be reduced, and further, the garbage can be efficiently dried in a short time. Furthermore, since the garbage processing machine can be automatically operated in accordance with changes in the outside air humidity, the operation is simplified and versatility is enhanced.

  It should be noted that the control method and apparatus for the garbage processing machine according to the present invention are not limited to the above-described illustrated examples, and it goes without saying that various changes can be made without departing from the scope of the present invention.
