[0021]
Next, the operation of this embodiment configured as described above will be described.
Raw garbage to be treated is put into the garbage container 3, and the garbage container 3 is set in the treatment tank 2. When the lid 11 is closed, the air guide tube 45 on the inner surface of the lid is fitted into the opening of the trash container 3. At this time, the blower guide tube 45 is attached in close contact with the closing body 53 provided on the outer peripheral surface so that there is no gap with the inner surface of the trash container. When it is confirmed by the lid switch 52 and the magnetic sensor 55 that the lid body 11 is closed and it is confirmed by the drainage container switch 44 that the drainage container 4 is set in the drainage chamber 43, a menu acceptance state is obtained.
[0022]
When a desired menu is selected by the menu keys 79 and 80 in the menu reception state, a program corresponding to the selected menu is executed. Here, the “Original” menu is based on the “Standard” menu and customized according to the type of trash to process each set value (temperature, humidity, and time). The basic operation is the same as the “Standard” menu. It is. The operation of the “standard” menu will be described below with reference to the flowchart of FIG.
[0023]
When the program of the “standard” menu starts, an initial heating process for driving only the microwave irradiation device 5, the blower fan 6, the exhaust fan 7, and the container drive motor 8 is first executed (1). This process is a process for removing moisture from the garbage to some extent before the garbage is agitated by the rotary blades 9. The microwave is irradiated while rotating the garbage container 3, and the blower fan 6 and the exhaust fan are exhausted. By allowing the air to flow through 7, microwaves are applied to the garbage without any unevenness, and at the same time, the removed water is smoothly discharged to the outside air. Thereby, it can prevent that refuse will couple | bond together by subsequent stirring.
[0024]
When the exhaust temperature generated from the garbage rises to a predetermined value and the exhaust humidity decreases to a predetermined value by the initial heating process, a primary stirring process is performed in which the blade driving motor 10 is driven for several seconds to rotate the rotating blade 9. Executed (2). This step is a step for stirring the garbage and discharging the steam confined in the garbage, and is performed every time the exhaust humidity decreases by a certain amount. Thereby, dispersion | distribution of the heating position by a microwave is achieved, and the water | moisture content in garbage is discharged | emitted actively.
[0025]
When the primary agitation process proceeds and the exhaust humidity decreases to a predetermined value, a secondary agitation process is performed in which the blade drive motor 10 is intermittently driven to intermittently rotate the rotary blade 9 (3). This process is a process for finally removing moisture contained in the garbage without combining the garbage, and is executed until the exhaust humidity is reduced to the limit value. As a result, the garbage that has been dispersed moderately by the primary stirring is further finely separated, and the moisture is discharged in detail.
[0026]
When the secondary agitation process is completed, the blade driving motor 10 is continuously driven to perform a dry garbage crushing process (4). This step is a step of reducing the amount of raw garbage from which moisture has been almost removed to reduce the amount. After confirming that the exhaust temperature has increased to a predetermined value after a predetermined time has elapsed since the start of the process, the microwave irradiation device 5 is rotated. The blade 9 is stopped.
[0027]
After the operation is completed, a cooling process is performed in which the blower fan 6, the exhaust fan 7, and the container drive motor 8 are continuously operated to cool the processed dust and the microwave irradiation device 5 (5). Thereafter, when the exhaust temperature is lowered to a temperature at which dust can be easily taken out, the blower fan 6, the exhaust fan 7, and the container drive motor 8 are stopped and the operation ends.
[0028]
Now, during such a process, the dust that has been dried and subdivided in the garbage container 3 rises due to the blowing by the blower fan and the rotation of the rotating blades, but the gap between the garbage container 3 and the blowing guide cylinder 45 is raised. Is closed by the closing body 53, so that the soared dust does not scatter in the treatment tank.
[0029]
The garbage after being treated in this way is in a reduced and fragmented state, and the garbage container 3 is removed from the treatment tank 2 and discarded. Moreover, the water | moisture content discharged | emitted from the waste container 3 bottom face is stored in the drainage container 4 through the drainage drain 27 from the drain outlet 19 of the processing tank 2, and after processing, this container is taken out and discarded.
[0030]
The shape of the closing body 53 is not limited to the above, and various embodiments are conceivable. 8-10 show another embodiment of the closure.
8 is made of a soft material such as a heat-resistant sponge and is inscribed in the inner surface of the garbage container. Since the waste container 3 is coupled to the bottom surface of the processing tank by a lower mounting member, the upper portion is likely to be rattled, so that the degree of adhesion may be partially different in the fitting to the air blowing guide tube 45. By configuring the closed body with a soft material such as sponge as in this embodiment, a certain degree of tolerance is possible, and the rotational resistance of the garbage container 3 can be reduced.
[0031]
9 is made of a flexible material such as rubber, and contacts the inner surface of the waste container with the lips L1 and L2 to seal the gap s. It has a high degree of adhesion to the inner surface of the trash container and can surely prevent trash from being scattered.
[0032]
10 is formed in an umbrella shape so as to cover the upper surface of the opening of the trash container 3 to seal the gap s with the trash container 3. Shaking when the garbage container 3 is attached can be allowed.
[0033]
【The invention's effect】
Since the present invention is configured as described above, the air guide tube that fits inside the opening of the garbage container is provided on the inner surface of the lid, and the air guide tube is provided with a closing body that closes the gap between the dust container, Garbage that jumps up by blowing or crushing does not jump out of the garbage container and contaminates the inside of the treatment tank.
