It's included. Then, while the mixer motor 13 and the stirring motor 25 are in operation, the lid body is 21 is opened, the safety switch 39 sends a signal to the control hand that the lid 21 has been opened. The control means 31 controls the mixer motor 13 and stirring motor for safety. When the timer 35 is stopped at the same time as the operation of the meter 25 is stopped, and the lid body 21 is closed, This will allow subsequent processing to continue.

[0015] Furthermore, the control means 31 includes a mixer motor start/stop switch provided on the support base 7. Signals from a switch 43 and a stirring motor start/stop switch 45 are input. Both operation/stop switches 43 and 45 operate the mixer motor 13 and stirring motor 25. It is operated and stopped manually, and the operation from these start/stop switches 43 and 45 is When the control means 31 inputs the signal, the control means 31 controls the mixer motor 13 and the stirring motor 13. The motor 25 is operated and stopped independently. And at this time, the operation The above-mentioned automatic control performed by turning on the operation switch 33 is not performed; These start/stop switches 43 and 45 are used for stop operation when automatic control is being performed. When the mixture is mixed, the mixer motor 13 and the stirring motor 25 are stopped and their automatic control is stopped. It is set to be removed.

[0016] In addition, in Figure 1, 47 is an operating lamp, 49 is a socket, and 51 is a plug. The household garbage disposal device related to this example can now operate on household 100 volts. ing. Further, 53 is attached to the lid body 21 in order to promote the fermentation of the garbage in the input container 1. A deodorizer filled with activated carbon is installed in the ventilation pipe 53 to prevent fermentation odors. 55 is attached.

[0017] This embodiment is configured as described above, and next, based on the flowchart of FIG. , the process of processing food waste by the household food waste processing apparatus of this embodiment will be explained. First, open the lid 21 and put the garbage into the container body 3, and at the same time Add the additive. In addition, the ratio of the amount of food waste and additives depends on the type and amount of food waste. Calculate it in advance. Then, close the lid 21 and turn on the operation switch 33. (Step S1).

[0018] When the operation switch 33 is turned on in this manner, the timer 35 starts operating. At the same time (step S2), from the control means 31 which inputs the signal of the operation switch 33, The mixer motor 13 starts operating in response to the command, and the mixer blades 15 rotate (step Step S3), the garbage in the input container main body 3 is crushed. The timer 35 measures the operating time of the mixer motor 13, and in step S4 It is determined whether the mixer motor 13 has operated for a preset period of time. Ru. Then, when it is determined in step S4 that a certain period of time has elapsed, step S5 Then, the mixer motor 13 is stopped by a command from the control means 31, and the mixer blades 15 are turned off. Rotation stops. Also, if it is determined in step S4 that the certain period of time has not elapsed. In some cases, the process returns to step S3.

[0019] Next, the control means 31 stops the operation of the mixer motor 13, and then turns on the stirring motor. Since the stirrer 25 is activated and the stirring blade 27 is rotated (step S6), the powder is not crushed. The garbage in the charging container main body 3 is then stirred by the stirring blade 27. Similarly, it is determined whether or not the stirring motor 25 has been operated for a preset period of time. When it is determined in step S7 that a certain period of time has elapsed, Proceeding to step S8, the stirring motor 25 stops, and the stirring blade 27 stops rotating. Ru. Incidentally, if the certain period of time has not yet elapsed, the process returns to step S6. Ru.

[0020] As described above, in this embodiment, approximately 30 seconds after the operation switch 33 is turned on, Fermentation and weight reduction processing of the garbage is completed in a few hours and it is composted, so in step S9 is whether three hours have elapsed since the operation switch 33 was turned on in step S1. is judged. Then, when it is determined in step S9 that 3 hours have passed, the raw The process proceeds to step S10 with the completion of the process, and the completion buzzer 37 sounds and the process is completed. The timer 35 then stops (step S11), and a series of processing steps for the garbage are started. The process will end.

[0021] For example, if the lid 21 is opened while the mixer motor 13 is in operation, the safety switch Since the switch 39 outputs a signal to that effect to the control means 31, the control that inputs that signal For safety, the control means 31 stops the operation of the mixer motor 13 and closes the lid body 21. Once completed, the subsequent processing will continue. At this time, the progress of Tie 35 was stopped. Stop.

[0022] Furthermore, without performing the process shown in the flowchart shown in FIG. Operation of motor start/stop switch 43 and stirring motor start/stop switch 45 Depending on the operation, the mixer motor 13 and the stirring motor 25 are operated independently to mix the raw garbage. It is also possible to carry out fermentation and weight reduction treatments, but these steps may be carried out during the process shown in Figure 3. If the start/stop switches 43 and 45 are stopped, the mixer motor 13 and stirring The motor 25 is stopped and the series of steps is canceled.

[0023] In this way, this example makes it possible to compost food waste generated at home. Of course, after pulverizing the garbage put into the container main body 3 in the mixer 11, Since the garbage is stirred by the stirring device 23, it is possible to stir the garbage using the stirring device 23. Fermentation and reduction of food waste, which required 24 hours in the household food waste processing device of Publication No. 81, was completed. According to this example, quantification can be completed in 3 hours, dramatically increasing the processing speed of garbage. It has improved dramatically.

[0024] In addition, in this embodiment, the crushing and stirring of garbage is automatically done by a timer. Therefore, in order to promote fermentation, I sometimes turn the handle by hand to stir the garbage. This eliminates the hassle of stirring, making processing extremely easy. Moreover, the household garbage disposal device according to this embodiment can use a household power source. There are no particular problems in terms of energy saving measures.

[0025] Note that the crushing means and stirring means in the present invention are the mixer 11 and the stirring device of the above embodiment. It is not limited to the structure of 23, but can reliably crush and stir food waste. Of course, other structures may be used as long as they are suitable for use.
