The present invention relates to a food waste treatment device having a temperature compensation structure in winter, and more specifically, in agitation, fermentation, and decomposition of food waste, deodorizing the gas exhausted in winter and supplying it to the fermentation tank again saves energy and provides outside temperature. It is possible to compensate for the temperature due to the drop, the food waste treatment device of the winter temperature compensation structure that can increase the fermentation, decomposition effect.

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 the surrounding drinking water or air. .

In the example food waste processor shown in FIG. 1, an input door 12 for inputting the residue and an discharge door 21 for removing the residue after treatment are formed on the outside of the main body 10 of the food waste processor made of a heat insulator. The inside of the main body is provided with a fermentation tank 11 for processing the residue and a deodorizer 30 for removing odor generated during the residue treatment process. The fermentation tank 11 is detachably installed in the main body so as to be detachable when removing the residue, or configured to remove the residue through the opening and closing door 22.

Moreover, inside the fermentation tank 11, the stirrer 16 is rotatably mounted, and the residue is decomposed and processed by stirring and fermenting the fermentation agent and the residue added from the outside. The stirrer 16 is rotated forward and backward by receiving a driving force by the electric mechanism 13 by a chain, a timing belt, etc. which are provided in the fermentation tank 11, and the motor 14, such as an AC induction system.

An exhaust duct 19 having therein is installed to be configured to discharge the gas generated in the fermentation tank 11 to the outside.

However, according to the present invention, in Figs. 3 and 4, the exhaust port 52 is formed downstream of the exhaust fan 19 'of the exhaust duct 19, and the rotation door 40 capable of opening and closing the exhaust port 52 is provided. It is attached to the exhaust duct 19 via the hinge shaft 41.

In addition, the internal circulation passage 50 is formed so that the exhaust port 52 is opened when the rotation door 40 is closed, and the exhaust port 52 is closed by the rotation door 40 when the exhaust door 52 is opened. Is formed, and the inner circulation passage 50 is introduced into the fermentation tank 11 so that the exhaust gas deodorized by the deodorizing device 30 flows into the fermentation tank 11 when the circulation port 51 is opened. It has a circulating gas outlet 53 extending. The circulating gas outlet 53 is preferably as far from the exhaust port 52 as possible.

In addition, the rotation door 40 may be connected to the manual rotation lever 44 is fixed to the hinge shaft 41 so as to operate manually, the temperature sensor 17 and the microcomputer 20a shown in Figs. It may be connected to the solenoid 43 via the connecting member 42 to be easily controlled by the). Other configurations may be configured as in FIGS. 1 and 2.

The operation and effects of the food waste treatment device having the winter temperature compensation structure configured as described above will be described with reference to FIGS. 1 to 4.

First, by opening the input door 12 in FIG. 1 and injecting food waste, the temperature sensor (shown in FIG. 2) when the input door 12 is closed by an input door sensor (not shown). 17) and the current temperature and humidity values from the humidity sensor 18 are input to the microcomputer 20a via the A / D converters 20b and 20c, and then through the driving units 20d and 20e according to a predetermined program. By driving the heater 15, the motor 14, the suction fan 19 and the exhaust fan 19 ', the temperature and humidity are adjusted to 20 to 30 ° C and 40 to 60%, and the stirrer 16 is intermittently settled. The food waste is decomposed and processed by stirring and fermenting the food waste introduced under optimal fermentation or decomposition conditions with the fermentation agent externally rotated by reverse rotation.

When the manual rotation lever 44 is mounted, the exhaust port 52 is artificially opened when the outside air is below a predetermined temperature to maintain the temperature inside the fermentation tank 11 and to evacuate to the atmosphere intermittently. By discharging the internal gas to the outside to effectively maintain the fermentation conditions with energy saving and to process food waste and the generated gas can be discharged to the atmosphere by removing the odor by the deodorizer (30).

On the other hand, the rotation door 40 is rotated together with the hinge shaft 41 by the operation of the solenoid 43 via the connecting member 42 to selectively open and close the circulation port 51 and the exhaust port 52. When configured, the microcomputer 20a can be controlled automatically.

By operating the solenoid 43 in any one direction through the driving unit (not shown), the circulation port 51 is opened and the exhaust port 52 is closed.

As the circulation port 51 is opened in this way, the internal circulation passage 50 is opened to pass through the deodorizer 30, and the gas from which the odor is deodorized passes through the internal circulation passage 50 by the exhaust fan 19 ′. It is discharged to the circulating gas outlet 53 is supplied to the upper portion of the fermentation tank (11). The gas retains almost all of its internal heat, so that even if the heater 15 is not operated at all, or only a little, the gas can be maintained at a predetermined temperature condition. In particular, when the temperature of the air in the winter is very low so that only the heater 15 can not maintain the internal temperature, it can be advantageously used, and by setting the above-mentioned reference value appropriately, energy will be greatly saved even in winter. .

When the inner circumferential temperature of the fermentation tank 11 rises or the humidity is high, the solenoid 43 is operated in the other direction by the microcomputer 20a to close the circulation port 51 and open the exhaust port 52. The gas can be released to the outside atmosphere.

On the other hand, when the intake fan 19 is operated together in accordance with the humidity of the fermentation tank 11 to control the humidity conditions, the outside and the internal circulation gas may be mixed and supplied to the fermentation tank (11).

In the above-described embodiment, the internal circulation is also performed using the exhaust fan 19 ', but it is also possible to control the installation of a separate internal circulation fan. In this case, a predetermined space is provided between the deodorizing device 30 and the exhaust fan 19 'without a separate internal circulation passage 50, a circulating gas outlet is formed in the space, a rotation door is installed, and the circulating gas By installing the circulation fan at the outlet, it is possible to circulate the internal gas by removing the odor by opening the rotating door and operating the circulation fan.

In addition, the rotation door 40 is configured to open and close only one of the circulation port 51 to the exhaust port 52, or the rotation door is installed on both sides of the circulation port 51 and the exhaust port 52 to discharge to the atmosphere. And internal circulation can be performed simultaneously, and by controlling the opening of the rotating door, it will be possible to control the discharge and internal circulation relatively.

In addition, although the internal circulation passage 50 is formed up and down in FIG. 3, the internal circulation passage 50 may be provided before and after the food waste processor.
