It has. A leg portion 24 is provided at the bottom of the container body 20, and the processing tank 16 is housed at the upper end side inside the container body 20.

The upper end surface of the processing tank 16 is bent to correspond to the lower shape of the lid 22, and an elastic material such as synthetic resin for engaging the lower portion of the lid 22 to seal the inside of the processing tank 16. A seal 26 composed of a body is provided so as to surround the upper opening 16 a of the processing tank 16.

An intake pipe 30 is provided in the container body 20, the upper end of the intake pipe 30 communicates with the upper side of the side of the processing tank 16, and the lower end of the intake pipe 30 is the vacuum pump 18.
Is connected to the suction port. The vacuum pump 18 is a rolling piston type (rotary type) electric vacuum pump, and is connected to the motor 32. This vacuum pump 18
One end of the exhaust pipe 34 is connected to the discharge port side of
The other end of the exhaust pipe 34 is a deodorizer (deodorizing means) for deodorizing the air sucked by the vacuum pump 18.
Connected to 36.

The deodorizer 36 includes a casing 38 having a sound deadening function by forming a relatively large chamber, and the casing 38 is filled with a deodorant 40. A discharge port 42 is provided at one end of the lower portion of the casing 38, and the discharge port 42 penetrates the lower portion of the container body 20 and projects to the outside.

A controller 44 for driving and controlling the motor 32 is provided in the container body 20, and a timer 46 is provided in the controller 44. The outlet 48 connected to the controller 44 is the container body 20.

Next, the operation of the thus constructed food waste processing apparatus 10 will be described.

First, after the operator grips the handle 23 and removes the lid 22 from the container body 20, the processing tank 16 is removed.
Garbage 14 is introduced inside. Then, when the lid 22 is placed on the upper portion of the container body 20, the inside of the processing tank 16 is sealed by the lower portion of the lid 22 and the seal 26, and the switch 50 is turned on in this state.

Therefore, the motor 32 is energized via the controller 44, the vacuum pump 18 is driven, and the processing tank 16 communicating with the vacuum pump 18 via the intake pipe 30 is provided.
The air inside is sucked. By sucking the air in the sealed processing tank 16, the pressure in the processing tank 16 is reduced from the atmospheric pressure state, and a desired negative pressure state is formed.
Therefore, the water in the garbage 14 in the processing tank 16 is removed by evaporation, sucked together with air, and introduced into the deodorizer 36 from the intake pipe 30 through the vacuum pump 18 and the exhaust pipe 34.

As a result, the air containing the odor of the raw garbage 14 is deodorized by the deodorant 40 filled in the casing 38, and then discharged from the outlet 42 to the container body 2.

That is, the deodorizer 36 has a function as a silencer in addition to the deodorizing function.

When the switch 50 is turned on, the timer 46 starts counting time. Then, when the clocking is finished and the driving of the motor 32 is stopped, the vacuum drying process of the garbage 14 is finished.

Here, if the amount of the garbage 14 in the processing tank 16 changes, the time taken for the inside of the processing tank 16 to reach a predetermined negative pressure state differs. Therefore, as shown in FIG. 2, the time required to reach a predetermined negative pressure state when the amount of food waste 14 is maximum (time from T ₁ to T ₂ )
Is set in the timer 46, and the motor 32 is driven for the set time regardless of the amount of the garbage 14. In FIG. 2, after the switch 50 is turned off, the pressure gradually rises toward the atmospheric pressure. This is because the air naturally enters the processing tank 16 side from the stopped vacuum pump 18. It shows a pressure recovery state due to the above.

As described above, the lid 22 is removed from the container body 20 after the vacuum drying of the garbage 14 is completed,
The inside of the processing tank 16 is returned to atmospheric pressure. Then, the dry waste in the processing tank 16 is processed as combustible waste, organic fertilizer, or the like.

In the first embodiment, the raw garbage 14 is dried in a short time with a simple structure by depressurizing the inside of the processing tank 16 accommodating the raw garbage 14 by the vacuum pump 18. The effect of being able to be obtained is obtained. In particular, it is only necessary to energize the vacuum pump 18 with the motor 32, and there is an advantage that the consumed electric energy is greatly reduced as compared with the conventional apparatus of the hot air drying type. Further, by drying the raw garbage 14, the total amount of garbage is reduced all at once, and the total amount of waste to be discarded is greatly reduced as compared with the conventional microbial system device.

Next, referring to FIG. 3 to FIG.
The garbage processing device according to the embodiment will be described.
