A kitchen garbage processing apparatus main body 2 is provided inside a kitchen table 1 such as a kitchen unit, and a rotatable stirring blade 4 is provided in a garbage processing tank 3 of the kitchen garbage processing apparatus main body 2. . The garbage processing tank 3 is filled with a garbage processing material 5, and the garbage is decomposed by the action of microorganisms such as bacteria that inhabit the garbage processing material 5. An input port 7 is provided on a kitchen table surface 6 which is an upper surface of the kitchen table 1, and the input port 7 is provided with a lid 8 which can be opened and closed, and a duct 9 is provided between the input port 7 and the food waste treatment tank 3.
It is communicated with. An outdoor exhaust port 10 is provided outside the outdoor wall 15 of the building, and the outdoor exhaust port 10 communicates with the garbage disposal tank 3 through an exhaust path 11.
A fan 12 for exhausting air and a deodorizer 13 of a catalyst heating type are arranged in the middle of the process. The blower fan 12 and the deodorizer 13 are incorporated in the garbage processing apparatus main body 2. Reference numeral 14 denotes a sink, and reference numeral 16 denotes an overflow container that receives excess garbage disposal material 5 overflowing from the garbage disposal tank 3. The overflow container 16 is provided with an air suction port 24 for taking in outside air into the garbage processing tank 3, and the garbage processing apparatus body 2 is provided with an air suction port 25 for taking in air for diluting exhaust gas. It is.

Above the garbage disposal tank 3, a circulation pipe 17 having both ends connected to the garbage disposal tank 3 and communicating with the inside of the garbage disposal tank 3 is provided. An air outlet 18 is provided at the end of the duct 9 near the lower end of the tank 3, and the other end of the circulation pipe 17 is connected to the opposite side of the duct 9 as viewed from the air outlet 18 and is connected to this end. The portion is an air inlet 19. The air blowing hole 18 adjusts the direction of the air blowing hole so that the air is blown obliquely downward (in the direction of the arrow A in FIG. 1) directly below the lower end opening of the duct 9. The direction of the holes is not adjusted as described above.
The air may be blown obliquely downward just below the lower end opening of the duct 9 by providing a guide portion for guiding the direction in which the air blows out. A circulation fan 20 is provided in the vicinity of the air outlet 18 in the middle of the circulation pipe 17, and the circulation fan 20 is driven when the inlet 7 is opened. Air in garbage disposal tank 3

In such a garbage processing apparatus, garbage generated in the kitchen is thrown into the garbage processing tank 3 from the input port 7,
The garbage is decomposed by the action of microorganisms living in the garbage processing material 5. When the garbage is not introduced from the inlet 7, the lid 8 is closed, and when the blast fan 12 is driven, fresh air is sucked into the garbage processing tank 3 and the air in the garbage processing tank 3 is removed. Is exhausted outdoors. That is, when the blower fan 12 is driven,
Fresh air is sucked into the garbage disposal tank 3 through the overflow container 16 through the air suction port 24, and the exhaust gas containing odor from the garbage disposal tank 3 passes through the exhaust path 11 to be deodorized. Deodorized at 13 and outdoor exhaust port 10

When the garbage is put into the garbage disposal tank 3, the lid 8 is opened and garbage is put into the garbage through the inlet 7, but when the garbage is open, the garbage is passed through the duct 9 and the inlet 7. The odor may flow back into the room. Therefore, when the charging port 7 is opened, the circulation fan 20 is driven to draw air in the garbage disposal tank 3 into the circulation pipe 17 from the air suction port 19, and to flow air from the air blowing hole 18 directly below the lower end opening of the duct 9. The air blows obliquely downward toward the duct 9, and the blown air enters the duct 9 and blocks or gets into the odor in the garbage disposal tank 3 that is going to flow backward, so that the odor enters the lower end opening of the duct 9. And the odor in the garbage disposal tank 3 can be prevented from flowing back through the duct 9 and entering the room through the inlet 7. Since the air is blown obliquely downward from the blowout hole 18, the blown air itself does not enter the duct 9 and flow back toward the room.

Further, the above-mentioned prevention of the backflow of the odor duct 9 in the garbage disposal tank 3 is performed not by the exhaust path 11 provided with the blower fan 12 and the deodorizer 13 but in the exhaust path 11.
Since it is performed by the circulation pipe 17 provided with another air blowout hole 18 and the like, it is not necessary to increase the air volume of the blower fan 12 of the exhaust path 11 as in the related art.
3 can be prevented from deteriorating the surrounding environment due to odor to the outside without lowering the deodorizing ability.

Next, an example of the embodiment shown in FIG. 2 will be described. This example is also basically the same as the above example, and only different points will be mainly described. In the case of this example, the circulation pipe 17 connects the inside of the duct 9 and the garbage disposal tank 3, and one end of the circulation pipe 17 is connected to the inner peripheral wall in the middle of the duct 9 and this end The circulating pipe 17 is connected to the upper part of the garbage disposal tank 3, and this end is used as an air suction port 19.

The direction of the air blowing hole 18 is adjusted so that air is blown obliquely downward (in the direction of arrow B in FIG. 2) into the duct 9.
The tip of 8 is substantially flush with the inner peripheral wall of the duct 9. Then, the air blown out from the air blowout hole 18 adjusted as described above blows obliquely downward into the duct 9, then hits the inner peripheral wall of the duct 9, changes its direction to below the duct 9, and It is discharged into the garbage disposal tank 3 from the lower end opening.

With the above configuration, when the lid 8 is opened to put garbage into the garbage disposal tank 3, air is blown from the air blowing hole 18 provided on the inner peripheral wall of the duct 9 to the duct 9. Is blown diagonally downward just below the lower end opening of the garbage disposal tank 3 and is discharged from the lower end opening of the duct 9 into the garbage processing tank 3, and this air flow tries to enter the lower end opening of the duct 9. Odor in the garbage disposal tank 3 can be prevented from invading the duct 9 and flowing back into the room through the inlet 7 by blocking the odor or entrapping and pushing back the odor flowing backward in the duct 9. It has become.

Next, an example of the embodiment shown in FIG. 3 will be described. This example is also basically the same as the above example, and only different points will be mainly described. In this embodiment, in addition to adjusting the direction of the holes of the air blowing holes 18 so that the air blown from the air blowing holes 18 blows substantially horizontally (in the direction of arrow C in FIG. 3) into the duct 9, In addition, an air suction hole 21 for sucking air blown out from the air blowout hole 18 is provided on the inner peripheral surface of the duct 9 facing the air blowout hole 18, and a return pipe for communicating the inside of the duct 9 with the inside of the garbage disposal tank 3. 23
Is connected to an air suction hole 21 and the other end is connected to an air outlet 22 formed in the upper part of the garbage disposal tank 3. The air blown out from the air blowout hole 18 adjusted as described above blows out substantially horizontally toward the duct 9 and reaches the air suction hole 21 provided on the inner peripheral wall of the duct 9 facing the air blowout hole 18. The air is discharged from the air discharge port 22 into the garbage disposal tank 3 through the return pipe 23.

With the above configuration, when the lid 8 is opened to put garbage into the garbage disposal tank 3, air is substantially horizontally discharged from the air blowing holes 18 provided on the inner peripheral wall of the duct 9. The air thus blown out flows into the air suction hole 21, and the odor in the garbage disposal tank 3 that flows backward in the duct 9 by the flow of the air is blocked or engulfed and pulled into the air suction hole 21. The odor in the garbage disposal tank 3 flows back through the duct 9 and the inlet 7
It can be prevented from entering the room from. Since the air suction hole 21 is provided in this manner, the air blown out substantially horizontally from the air blowout hole 18 hits the inner peripheral wall of the duct 9 to change the traveling direction upward and does not flow backward in the duct 9. . Further, the air discharged from the air discharge port 22 into the garbage disposal tank 3 passes under the lower end opening of the duct 9 and is sucked from the air suction port 19, so that the air is discharged from the air discharge port 22 through the lower end opening of the duct 9. The odor trying to enter the lower end opening of the duct 9 can also be blocked by the flow of air reaching the suction port 19.

Although not shown, in each of the embodiments shown in FIGS. 1 to 3 described above, the air blown out from the air blowout hole 18 is substantially the same as the area surrounded by the inner peripheral wall of the duct 9 in a horizontal view. The air blowing holes 18 may be formed so as to blow in a plane so as to cross the entire area.

In this manner, the air outlet 1
With the air blown out from the garbage processing tank 3, it is possible to form an air curtain that blocks a path through which the odor generated in the garbage processing tank 3 enters the room through the duct 9, and further increases the inside of the garbage processing tank 3. Is prevented from flowing back inside the duct 9 and entering the room through the inlet 7.
