The discharge tube 11 is divided into front and rear by a rear wall of the processing tank 1. A front part of the rear wall communicates with the inside of the processing tank 1 and constitutes a part of a circulation path described later. The exhaust port 12 formed in the lower case 7 communicates with an exhaust passage (not shown) formed on the back surface of the processing tank 1.

Reference numeral 13 denotes a substrate housing case which covers the upper side of the recess 9 in a state where a space is formed between the bottom surface of the recess 9 and the screw 9, and is fixed to the recess 9 by the planar heater 3, the illuminating device 5, A control board 14 on which a control circuit for controlling a fan 15 and an electric motor 17, which will be described later, is placed is housed, and the recess 9 and the board housing case are housed.
A space between the space 13 and 13 and the front portions of the intake cylinder 10 and the discharge cylinder 11 constitute a circulation path for circulating the air in the processing tank 1.

Reference numeral 15 is a fan mounted on the discharge tube 11,
The air in the processing tank 1 is sucked from the suction cylinder 10 by driving the fan 15, and is discharged from the discharge cylinder 11 through the space between the recess 9 and the substrate storage case 13. Since it is divided into front and rear by the rear wall of the processing tank 1, the intake cylinder 10

Reference numeral 25 denotes a lid body which is swingably supported on the upper surface of the upper case 23, and which closes the opening 24 so as to be openable and closable. The lid
The opening / closing of 25 is detected by an opening / closing detection means (not shown).

When the lid 25 is opened, a detection means (not shown) detects it, and the control circuit energizes the lighting device 5 based on the output. By energizing the lighting device 5, the inside of the processing tank 1 is illuminated through the carrier amount display plate 4, so that the amount and state of the carrier 2 can be easily confirmed even at night.

When an organic substance such as garbage is thrown into the treatment tank 1 through the throwing opening 24 and the lid 25 is closed, a detecting means (not shown) detects and the control circuit energizes the illuminating device 5 based on the output. And the electric motor 17, the planar heater 3 and the fan 15 are energized.

When the electric motor 17 and the sheet heater 3 are energized, the agitator 19 is rotated to mix the carrier 2 and the organic matter, and the temperature inside the treatment tank 1 is maintained in an optimum range for activating microorganisms and the like. Then, the organic matter is decomposed into carbon dioxide and water by the microorganisms cultured on the carrier 2 and composted.

By energizing the fan 15, the processing tank 1
The air inside is circulated through a circulation path to evaporate the water generated by the decomposition of organic matter, maintain the temperature and water content of the carrier 2 in the optimum range for activating microorganisms, etc., and to activate the microorganisms. Supply oxygen.

A part of the air circulating in the processing tank 1 is exhausted from the rear portion of the exhaust pipe 11 to the outside of the main body case through the exhaust passage and the exhaust port 12, so that the air in the processing tank 1 becomes over-humidified. And the efficiency of removing water in the treatment tank 1 is improved, the microorganisms are activated, and the organic matter treatment capacity is improved.

As the air in the processing tank 1 is exhausted to the outside, the outside air is taken into the main body case from the intake port 8 formed in the lower case 7, and the suction port 6 formed on the side surface of the processing tank 1
The air taken into the main body case is heated by the planar heater 3 and is mixed with the air circulating in the processing tank 1, so that the outside air temperature in winter or the like is low. Even at this time, it is possible to prevent a decrease in the organic substance processing capacity without significantly lowering the temperature in the processing tank 1.

When the organic substance treating apparatus is used for a long period of time, the carrier 2 reaches the end of its life and the amount of undecomposed organic substance in the treatment tank 1 increases. When the amounts of the carrier 2 and the undecomposed organic matter in the processing tank 1 reach the upper limit level, the carrier 2 covers the carrier amount display plate 4, so that the lighting device 5 illuminates the inside of the processing tank 1 even if the lid 25 is opened. It becomes impossible, and the user can easily recognize the replacement time of the carrier 2.

[0027]

According to the structure of claim 1 of the present invention, since the inside of the processing tank is illuminated through the carrier amount display plate, the amount and state of the carrier in the processing tank can be easily confirmed even at night. In addition to the advantages, the user can easily recognize the replacement time of the carrier.

According to the second aspect of the present invention, since the inside of the processing tank is illuminated via the carrier amount display plate, the amount and state of the carrier in the processing tank can be easily confirmed even at night. In addition, the user can easily recognize the replacement time of the carrier. Further, since the lighting device is controlled only when an organic substance is put in and the lid is opened, the durability of the lighting device can be improved and the electric bill can be saved.
