Description

A method of determining disposal finishing time of a food garbage disposer}

The present invention relates to a method for determining a food processing completion time of a food processor, and in particular, to determine a food processing completion time of a food processor that efficiently determines the time at which the operation of food waste processed through a series of processes in a drying furnace is completed. It is about a method.

In general, food wastes discharged from homes or restaurants often contain large amounts of water, and these food wastes are a social problem because they can cause environmental pollution and infectious diseases.

Accordingly, recently, a food waste treatment method for separating and collecting food waste separately has been enacted so that food wastes can be discharged in household bags and food businesses in garbage bags without leach water.

If food is stored in a garbage bag, the food may rot, causing a bad smell, flies gather around the food waste in summer, or bacteria may grow.

Therefore, in order to efficiently control the generation and recycling of food waste, it is urgently required to develop a food processor that can reduce the environmental pollution caused by food waste and recycle it.

Devices that dispose of food waste connected to home sinks or located separately from sinks typically use a series of processes, such as stirring, dehydration, cutting, and drying, to remove water from food waste, and to reduce volume and significantly reduce emissions. It can be done.

On the other hand, the food waste from which residual moisture is completely removed by the high heat inside the drying furnace is discharged in its entirety through an outlet formed through the bottom of the drying furnace, and the new food waste dehydrated and cut continuously in the drying furnace where all the food waste is discharged. It is re-injected and the drying operation of food waste is performed again.

The food processor as described above continuously feeds food waste into the drying furnace through the inlet in a state in which a certain amount of fermentation agent is filled in the drying furnace, adjusts the amount of water to an appropriate state, and then adjusts the proper temperature through a heater to dry it. Air is introduced into the furnace.

If the inside of the drying furnace is maintained in this state, the fermentation of the fermentation bacteria is aerobic fermentation, and the food waste is extinguished, and is properly maintained by the stirring device installed inside the drying furnace. 50% to 60% is maintained and the temperature is maintained at 45 ~ 55 ℃.

The food waste is reduced by a series of operations as described above, and made into a stable organic compost. When the food waste processing is completed, the food waste is sent to the collection box through the opening and closing unit, and the user separates the collection box from the main body and discards the food waste contained in the collection box. It will be disposed of.

However, the conventional food processor has a problem in that decomposition is not properly performed within a set time according to an incorrect operation because the user needs to set a treatment environment by directly operating a waste input amount, a culture temperature, an operation time, and the like.

For example, when a small amount of food is added and the incubation temperature is set too high or the humidity is set too low, the growth of microorganisms is suppressed and thus the decomposition of food is delayed and unnecessary power is consumed.

In addition, since the user cannot usually determine at what point the operation of the food waste processed through a series of processes such as stirring, dehydration, grinding and drying in the drying furnace, the user frequently checks each time the food processing apparatus is operated. There was an inconvenience to do.

1 is a schematic block diagram of a food processor capable of determining a food processing completion time in accordance with the present invention, the command input and display unit 100, power supply unit 200, data storage unit 300, heater 400 , Heater temperature sensor 500, drying furnace humidity sensor 600, power unit 700, CT converter 800, control unit 900, discharge motor 920, recovery box 950, The input and display unit 100 includes various command input buttons including a power button and a food processing completion indicator.

Referring to Figure 1 describes the function of each block of the food processing completed processing apparatus of the food processor according to the present invention.

The command input and display unit 100 starts or stops the operation of the food processor through the power button, inputs various operations of the food processor through the operation of various command input buttons, and the food processing completion indicator to the user at the time of food processing completion. Provide information.

The power supply unit 200 supplies power in response to the command of the command input and display unit 100.

The data storage unit 300 is an operation state of the food processor over time, that is, the temperature and temperature change cycles of the heater 400 and the voltage change of the power unit 700 regardless of the power supply from the power supply unit 200. The values, humidity of the drying furnace, etc. are recorded and erased electrically.

The heater 400 heats the drying furnace in response to the control of the controller 900 to dry the food waste.

The heater temperature sensor 500 detects and outputs a temperature of the heater 400.

Drying furnace humidity sensor 600 detects and outputs the humidity of the drying furnace.

The power unit 700 operates for a predetermined time in response to the control of the control unit 900 to transmit power to a drying furnace. One example of the power unit 700 is a grinding motor.

The CT converter 800 converts the current value (Current Transform, CT) raised by the operation of the power unit 700 to a voltage value and outputs a voltage change value.

The control unit 900 receives the temperature change value of the heater 400, the voltage change value of the power unit 700, and the humidity change value of the drying furnace from the respective sensors, and turn on / off the heater 400, respectively. , After determining the voltage falling from the maximum value of the current change value, the water vapor discharge to the drying furnace, the reference value of the on / off cycle reference value of the heater 400 at the completion of food processing stored in the data storage unit 300, the reference value of the voltage change amount Read the voltage value and the humidity reference value of the drying furnace and compare them to determine the completion of food treatment.

Here, the reference voltage value is preferably 0.8 to 1.2V.

When it is determined that the food processing time is completed, the operation of the heater 400 is stopped, the discharge motor 920 is driven, the command input and display unit 100 is displayed on the food processing completion indication light, and the food processing completion time is not determined. If not, control to continue normal operation.

The discharge motor 920 is driven to discharge the processed food waste to the recovery box 950 through a series of processes such as stirring, dehydration, grinding and drying in the drying furnace.

Figure 2 is a flow chart showing the operation of the food processing completion time determination method of the food processor according to the present invention.

3 is a graph showing a change in the heater 400 temperature with the passage of the food processor operation time according to the present invention, Figure 4 is a voltage of the CT converter 800 with the passage of the food processor operation time according to the present invention 5 is a graph showing a change in, Figure 5 is a graph showing a change in humidity of the drying sensor detected by the humidity sensor as the operation time of the food processor in accordance with the present invention.

1 to 5, the operation of the food processing completion time determination method of the food processor according to the present invention will be described with reference to specific embodiments.

First, the data storage unit 300 has an on / off cycle reference value Tref of the heater 400 at a food processing completion point Tfin, a reference voltage value Vref of a voltage change amount, and a humidity reference value Vref of a drying furnace. Save it. (S100)

Here, the data storage unit 300 preferably uses an EEPROM (electrically erasable and programmable read only memory) that is a nonvolatile memory device that stably stores for a long time even when the power is turned off.

The EEPROM is a modification of the erasable and programmable read memory device (EPROM) that can be erased and rewritten once the data has been written once, making it convenient for applications that require rewriting of the program.

The ability to read or write electrically allows the program to be rebuilt within the system and the recorded data is retained long without power.

When the user turns on the power button of the command input and display unit 100 to operate the food processor (S150), the heater 400, the heater temperature sensor 500, the drying furnace humidity sensor 600, the power unit 700, The CT converter 800 starts to operate.

The heater 400 heats the drying furnace in response to the control of the controller 900 to dry the food waste, and the heater temperature sensor 500 detects and outputs the current temperature of the heater 400, and the power unit 700 controls the controller. In response to the control of the 900, the operation for a predetermined time to transmit power to the drying furnace, etc., CT converter 800 converts the current value raised by the operation of the power unit 700 to a voltage value to change the voltage change value And, the drying furnace humidity sensor 600 detects and outputs the current humidity of the drying furnace (S200).

As shown in FIG. 3, as the food processor operates, the heater 400 repeats the on / off operation with different cycles, and the temperature of the heater 400 is repeatedly raised and lowered. As the on time of the heater 400 decreases closer to the time Tfin, the current on / off period of the heater 400 gradually decreases from the on / off period maximum value Tmax, and thus the food processing completion time Tfin. In, the on / off period reference value Tref is reached.

The controller 900 receives a temperature change value of the heater 400 over time from the heater temperature sensor 500 to determine a current on / off cycle of the heater 400 (S250) to the data storage unit 300. It is compared with the on / off cycle reference value Tref of the heater 400 at the food processing completion time point Tfin stored therein (S300).

If the current on / off period of the heater 400 decreases and falls below the on / off period reference value Tref, the control unit 900 may change the power unit 700 from the CT converter 800 over time. In response to the change in the consumption voltage, it is determined whether the power supply unit 700 has fallen below the reference voltage value Vref from the maximum consumption voltage Vmax, and the current on / off cycle of the heater 400 is turned on. In the case of larger than the / off period reference value (Tref) it is fed back to the step (S200) to detect and output the current temperature of the heater 400, the voltage change value of the CT converter 800, the current humidity of the drying furnace (S200) Control to repeat

That is, the power unit 700 operates for a predetermined time in response to the control of the control unit 900 to transmit power to the drying furnace, etc., and the CT converter 800 increases the current value raised by the operation of the power unit 700. When converting the voltage value and outputting the voltage change value, the controller 900 receives the voltage change value of the power unit 700 over time and determines the voltage value falling from the maximum value of the voltage change value.

As shown in FIG. 4, as the time when the food processor operates, the bonding force of the food increases, and as the load of the power unit 700 increases, the voltage consumed increases so that the maximum voltage consumption of the CT converter 800 increases. When the food is processed to some extent after reaching the Vmax, the bonding force of the food decreases, and as the load of the power unit 700 decreases, the voltage consumed decreases, and when the food processing is completed, the CT converter 800 The reference voltage value Vref is reached.

As a result of determining whether the power supply unit 700 has fallen below the reference voltage value Vref from the maximum consumption voltage Vmax of the power unit 700, the controller 900 changes the humidity change value of the drying furnace when it drops below the reference voltage value Vref. The water vapor discharged to the drying furnace is determined by the approval, and (S400), the control unit returns to the step (S200) and repeats the subsequent operation when it has not yet fallen below the reference voltage value (Vref).

When the drying furnace humidity sensor 600 detects and outputs the humidity of the drying furnace, the control unit 900 receives the humidity change value of the drying furnace to determine the amount of water vapor discharged from the drying furnace and at the final processing time of the food stored in the data storage unit 300. Compared with the humidity reference value (Href) of the drying furnace (S450).

As shown in FIG. 5, the amount of water vapor evaporated from the food waste increases as time passes by the operation of the food processor in the drying furnace which was initially at a constant humidity state (for example, 50%), and the amount of water vapor discharged from the drying furnace to the deodorization filter. As this increases, the humidity detected by the humidity sensor 600 in the drying furnace increases to reach the maximum humidity value Tmax, and when the food is processed to some extent, the amount of water vapor evaporated from the food waste decreases and the amount of water vapor discharged from the drying furnace to the deodorization filter. As this decreases, the humidity detected by the drying furnace humidity sensor 600 falls, and when the food treatment is completed, the humidity reference value Href of the drying furnace is reached.

As a result of comparing the current vapor discharge amount of the drying furnace with the humidity reference value (Href) of the drying furnace, when the current vapor discharge rate of the drying furnace falls below the humidity reference value (Href) of the drying furnace, the control unit 900 determines that the food processing time is completed ( In operation S500, the operation of the heater 400 is stopped and the discharge motor 920 is driven, and the command input and display unit 100 displays the food processing completion indicator in operation S550.

Accordingly, the discharge motor 920 is driven to discharge the processed food waste to the recovery box 950 through a series of processes such as stirring, dehydration, grinding and drying in the drying furnace.

If it is determined that the current vapor discharge amount of the drying furnace has not yet reached the humidity reference value (Href) of the drying furnace, the controller 900 determines that the food processing is not yet completed, and returns to the step S200. Control to repeat the operation.

As described above, the method for determining a food processing completion time of the food processor according to the present invention automatically detects the physical characteristics of the food waste being processed by the food processor and determines the temperature, the voltage consumption, and the humidity of the food processing process to automatically complete the food processing. By judging the time point, the food disassembly is delayed and unnecessary power is consumed due to a misoperation of the user's manual food processing environment setting, and whenever the food processor is operated at which point the food waste is disposed of This can prevent the inconvenience of checking frequently.
