The present invention relates to a food waste disposal device having a variable deodorization device that can be efficiently used.

In general, each home or restaurant, such as the leftover (food waste) is discharged every day, such residues are used as livestock feed or simply filtered through a strainer and then discarded. These residue treatment methods increase the amount of food waste in the total amount of waste, and if the food waste is not disposed of smoothly, it causes odors and pollutes nearby drinking water sources or air. .

In the example food waste processor of FIG. 1, an input door 12 for injecting the residue and a discharge door 21 for removing the waste after treatment are formed outside the main body of the food waste processor made of a heat insulator. The main body is provided with a fermentation tank 11 for processing residue and an exhaust duct 19 ″ for discharging fermentation gas and water vapor generated during the residue treatment process to the outside, and the fermentation gas 19 ″ is installed in the exhaust duct 19 ″. Deodorization chamber 30 for removing the odor is installed. The fermentation tank 11 is detachably installed in the main body so as to be detachable when removing the debris, or configured to remove the debris through the opening and closing door 22.

In addition, inside the fermentation tank 11, a stirrer 16 is rotatably mounted to decompose and treat the residue by stirring and fermenting the fermenter and the residue introduced from the outside. The stirrer 16 is rotated forward and backward by receiving a driving force by an electric mechanism 13 such as a chain, a timing belt, or the like, which is installed outside the fermentation tank 11, and a motor 14 such as an AC induction system.

Meanwhile, a suction fan 19 and an exhaust fan 19 ′ are installed at the upper portion of the food waste processor, and the suction fan 19 and the heater 15 installed therein are provided by a kind of fan heater function. If necessary, the outside air is heated and introduced, and the exhaust fan 19 ′ is generated in the process of stirring, reducing water evaporation and fermentative decomposition of food waste introduced through the input door 12 in the fermentation tank 11. The fermentation gas and water vapor are discharged to the outside via the deodorization chamber 30 installed in the exhaust duct 19 ".

At this time, the high voltage generator 31 for converting the low voltage power applied to the high voltage power capable of generating ozone (O ₃ ) and the high voltage from the high pressure generator 31 are applied to the deodorization chamber 30. receiving ozone using air (O ₃₎ to the ozone generating lamp 32 to generate is installed generated in the ozone generating lamp 32, ozone (O ₃₎ is a fermentation gas generated within the fermentation tank 11 as The reaction is to deodorize the fermentation gas first.

In addition, the waste ozone adsorption filter 33 for removing the waste ozone remaining after the ozone generated by the ozone generating lamp 32 and the fermentation gas in the fermentation tank 11 react with the ozone generating lamp 32. And a deodorization filter 34 for removing other odors remaining from the gas from which the waste ozone has been removed, and deodorizing the odor of the fermentation gas, etc., and then exhaust exhaust duct 19 " ) Can be discharged to the outside.

The motor 14, the heater 15, the suction fan 19, the exhaust fan 19 ′ and the like are connected to the control panel 20 using a microcomputer, so that the operation of the food waste processor is controlled by a predetermined level or program. It may be configured to be controlled. The control panel 20 also controls the operation of the food waste processor in a sequential or manual operation according to the set operation mode, and receives the input of the temperature sensor 17 and the humidity sensor 18 installed inside the fermentation tank 11. The internal temperature and humidity conditions also control the operation of the food waste handler. One example of the control system is shown in FIG.

After the food waste is put in FIG. 2, since the input door 12 is closed by the sensor 12 ′, the present temperature value and humidity value are A / A from the temperature sensor 17 and the humidity sensor 18. When input to the microcomputer 20a via the D converters 20b and 20c, the heater 15, the motor 14, the suction fan 19 and the exhaust fan 19 are passed through the driving units 20d and 20e according to a predetermined program.

And after deodorizing the waste ozone and other odors remaining through the deodorizing filter 34, and discharged to the outside, the ozone generating lamp 32 is installed in the exhaust duct (19 ") the fermentation tank (11) Ozone generated through the ozone generating lamp 32 due to the oxygen (O ₂ ) contained in the fermentation gas is not satisfactory because the fermentation gas inside the contact with the ozone generating lamp 32 to generate ozone ( By limiting the amount of O ₃ ), the ammonia (NH ₃ ) and the like of the fermentation gas cannot be sufficiently deodorized, and are discharged to the outside as it is. In addition, the ozone generation by the ozone generating lamp 32 is reduced. Without special restraint As a result of constant discharge, energy is generated by generating unnecessary ozone, and all exhaust gases pass through one deodorizing filter, resulting in shortening of the life of the deodorizing filter and deodorization performance.
