Is what you do.

By doing so, the inside of the food waste treatment tank 1 becomes negative pressure, and even if the opening / closing lid 4 is opened, the odor does not flow out from the charging port 5 to the indoor side. When the opening / closing lid 4 is in the open state, the control to make the air volume of the exhaust fan 7 larger than the air volume of the intake fan 6 is not limited to the above control, and the air volume of the fan may be continuously changed. . When the opening / closing lid 4 is closed, the air volume of the intake fan 6 and the air volume of the exhaust fan 7 are set to substantially the same air volume. What is necessary is just to control so that it may become larger than an air volume.

Here, as the intake fan 7 and the exhaust fan 7, either a DC fan or an AC fan may be used. Next, another embodiment of the present invention will be described with reference to FIGS. Also in this embodiment, the garbage disposal tank 1 is mounted on the outdoor surface of the outer wall 2, and a garbage input duct 3 penetrating from the indoor side to the outdoor side is protruded into the garbage disposal tank 1. An inlet port 5 provided with an opening / closing lid 4 is provided at an indoor side of the garbage disposal tank, and an intake fan 6 for sucking outside air into the garbage processing tank 1 and an exhaust fan 7 for exhausting the garbage processing tank 1 are provided.

The human body detection sensor 9 is provided, for example, on the insertion frame 11 to which the opening / closing lid 4 is attached as shown in FIG. FIG. 6 shows a control block diagram of the present embodiment. When a person reaches his hand on the opening / closing lid 4 provided at the insertion port 5, the detection is performed by the human body detection sensor 9, and a detection signal of the human body is transmitted to the control unit 8. It is output. And
When a signal indicating that a human body is detected by the human body detection sensor 9 is input to the control unit 8, the control unit 8 controls the air flow of the exhaust fan 7 to be larger than that of the intake fan 6.
In this manner, the air flow of the exhaust fan 7 is controlled to be larger than the air volume of the intake fan 6 when the user approaches the inlet 5 to open the open / close lid 4 before opening the open / close lid 4 by hand. Therefore, immediately before the opening and closing cover 4 is opened, the inside of the garbage disposal tank 1 is at a negative pressure. Is prevented. On the other hand, after opening and closing the lid 4 as described above and dumping garbage into the garbage disposal tank 1 from the input port 5, closing the open and close lid 4 by hand and leaving the hand near the input port 5, The human body is not detected by the human body detection sensor 9,
For this reason, the control unit 8 controls the air volume of the intake fan 6 and the exhaust fan 7 to be substantially the same.

In the present embodiment, in order to prevent malfunction, a person approaches the inlet 5, a human body is detected by the human body detection sensor 9, and the air volume of the exhaust fan 7 is made larger than the air volume of the intake fan 6. After the control, if the opening / closing cover 4 is not opened within a certain period of time and the opening / closing door 4 opening signal from the cover opening / closing detection switch 30 is not input to the control unit 8, the air volume of the intake fan 6 in normal operation and the exhaust fan 7 is controlled so as to have substantially the same air volume.

Also in this embodiment, the control of the fan is performed in three stages of strong, medium, and weak depending on, for example, the outside air temperature and the amount of garbage input, as in the above-described embodiment. Or change the air volume of the fan.
