First, the water tank level sensor 45 is formed in the form of a plurality of electrode rods of different lengths to detect the water level by energization when water is in contact with each electrode, the water level sensor of this configuration is conventional Since it is a well-known technology, description of the sensing process is omitted, but the process of controlling the display unit 58 by the sensing signal of the water tank level sensor 45 will be described.

That is, the micro process unit 57 reads the water level level signal output from the water tank level sensor 45 introduced into the water tank 10 through the drive 56 (step 101).

At this time, if the read water level is determined to be a high water level (step 102), the high water level lamp of the water tank water level display unit 58a, which is the display unit 58, is turned on (step 103), and the read water level is determined to be a medium water level. In step 104, the mid-level lamp of the water tank level display unit 58a, which is the display unit 58, is turned on (step 105), and when the read water level is determined to be low level (step 106), the display unit 58 At the same time, the low water level lamp of the water tank water level display unit 58a flashes (step 107) and an alarm sound is transmitted through the alarm display unit 58b (step 108).

It is easy to check the timing to provide convenience to the user.

Next, the process of supplying and blocking water from the water tank 10 to the drip tray 21 of the humidification cylinder 15 and detecting the water level change introduced into the drip tray 21 are illustrated in FIG. 9B. The following describes the process of measuring the failure status of).

First, the humidifier level sensor 25 is composed of a float 25a and a contact 25b as shown in the enlarged view shown in FIG. 7, and the drip part 21 of the humidifier cylinder 15 from the water tank 10. When water is supplied to the float 25a, the float 25a is raised by buoyancy to make contact with the contact 25b, and when the water level is lowered due to spraying by the vibrator 26, the float 25a is It is separated from the contact 25b by a load.

Therefore, the micro-process unit 57 reads the output signal of the humidifier level sensor 25 through the drive 56 (step 201), and when the water level is full, the float 25a is raised by buoyancy and thus the contact point ( The water level sensor 25 of FIG. 7 stops driving of the solenoid valve 11 (step 204) as the water level sensor 25 of FIG. 7 is connected to 25 b) to receive the water stored in the water tank 10. ) Will not be supplied.

In this state, the micro process unit 57 counts the time (step 205), and the float 25a and the contact 25b are not separated within five hours, that is, the humidifier level sensor 25 is turned on. After 5 hours (step 206), it is determined that the vibrator 26 is fixed (step 207) to stop the driving of the vibrator 26.

However, when water is atomized by the normal operation of the vibrator 26, the water introduced into the drip tray 21 is reduced in water level. As a result, the float 25a and the contact 25b are separated from each other by a load, thereby humidifying the humidifier. The level sensor 25 is to be kept off.

Accordingly, when it is determined that the humidifier water level sensor 25 is in the off state (step 203), the micro process unit 57 drives the solenoid valve 11 (step 203) to receive the water stored in the water tank 10. Will be supplied to (21).

As such, the humidifier water level sensor 25 automatically supplies the water stored in the water tank 10 to the drip tray 21 and senses whether the vibrator 26 is broken, thereby driving the vibrator 26 when an abnormality occurs. By stopping, the safety and precision can be increased.

8 and 10a, the frequency of the AC 220V commercial power source is 60 Hz in Korea, and the frequency of the AC 220V commercial power source is 50 Hz in Japan, which may be generated due to different frequency bands of commercial power in each country. The control process for controlling the driving of the stirring motor by detecting the frequency of the input power and the rotation speed of the stirring motor in order to prevent the malfunction of the system is as follows.

First, when AC 200V power, which is a driving power source, is applied to the food waste processing apparatus applied to the present invention as shown in FIG. 8, the square wave generator 66 extracts the frequency of the AC 220V commercial power source from the square wave generator 66, which is the stirring motor controller 67. The microprocessor unit 57 converts the output to the microprocessor unit 57, and counts the pulses applied from the square wave generator 66 to read the frequency of the AC 220V commercial power source.

At the same time, when the driving power is supplied to the food waste treatment apparatus and the stirring motor 5 is driven, the pulse detection sensor 64 generates one pulse when the rotation shaft of the stirring motor 5 rotates once. After the noise contained in the pulse is removed and stabilized via the noise removing unit 65, the micro process unit 57 is transmitted to the micro process unit 57 so that the frequency of the input power and the RPM of the stirring motor 5 are maintained. The overload condition is detected by the detection to control the stirring motor 5.

That is, FIG. 10A is a control flowchart of the stirring motor in the food waste treating apparatus according to the present invention. In the micro process unit 57, the pulse received from the square wave generator 66 of the stirring motor controller 67 is counted and used. An input power frequency determination process L1 is performed to determine whether the power supply frequency is 50 Hz or 60 Hz (steps 301 and 302).

In the input power frequency determination process (L1), when the frequency of the input power is determined that the frequency is 50Hz, the RPM of the current stirring motor (5) by reading the signal output from the RPM sensor 64 and the noise removing unit 65 After executing the first RPM determination process (L2) to determine whether or less than 1,000 or more than 1,000 (steps 303 and 304), if the RPM of the current stirring motor 5 is determined to be less than 1,000, the stirring motor 5 is overloaded Recognizing that the state is forcibly stopped driving (step 307), while if the current RPM of the stirring motor 5 is determined to be more than 1,000 stirring motor 5 recognizes that the normal state to maintain the drive (step 308) The first stirring motor control process L3 is performed.

In addition, when it is determined in step (302) that the frequency of the input power is 60Hz in the input power frequency determination process (L1), the signal output from the RPM sensor 64 and the noise removing unit 65 is read and the current stirring motor is read. After the second RPM determination process (L4) to determine whether the RPM of (5) is 1,300 or less or 1,300 or more (steps 305 and 306), the stirring of the current stirring motor (5) is determined to be 1,300 or less stirring The motor 5 forcibly stops driving by recognizing that it is in an overload state (step 309), and when the RPM of the stirring motor 5 is determined to be 1,300 or more, the stirring motor 5 recognizes that the driving state is normal. A second stirring motor control process (L5) to maintain (step 310) is performed.

In Korea, the frequency of AC 220V commercial power is 60Hz, and in Japan, the frequency of AC 220V commercial power is 50Hz, which prevents malfunction of the system, which may be caused by different frequency bands of commercial power in each country. It is possible to increase precision and reliability.

Next, the process of controlling the blowing amount of the blowing fan 54 according to whether the stirring motor 5 is operated by FIG. 10B will be described.

As described above, the agitation motor 5 is stopped due to the overload detection by the agitation motor controller 67, or a transient current flows through the agitation motor 5 by the overload detection unit 52 to force the agitation motor 5. When stopped, or when the fermentation of food waste is completed and the driving of the stirring motor 5 is stopped, the blower fan 54 supplied to the deodorizer 8 is rotated at a low speed to minimize power consumption.

That is, when a pulse is received from the RPM sensor 64 as shown in FIG. 10B, the stirring motor 5 recognizes that it is in operation, and when the pulse is not received from the RPM sensor 64, the stirring motor 5. Recognizes that it is stopped.

Therefore, when it is determined that the stirring motor 5 is in operation by reading the output signal of the RPM sensor 64 (step 401), the blowing fan 54 is rotated at high speed (step 402) and supplied to the deodorizer 8. If it is determined that the amount of blowing air is increased, on the contrary, if it is determined that the stirring motor 5 is at a standstill (step 403), the blowing fan 54 is rotated at a low speed (step 404) to reduce the amount of blowing air supplied to the deodorizer 8. It is possible to reduce the life and power consumption of the blowing fan (54).

As described above, the present invention is humidified by a user in a food waste processing apparatus provided with a deodorizing device for maintaining an optimal condition in which microorganisms capable of removing odors (fermented odor) generated during food waste fermentation can grow. The water tank level level of the device can be easily recognized and replenished, and when abnormalities occur in the humidifying device that provides moisture, the precision of the food can be improved by stopping the operation of the humidifying device. The user can select and use various kinds of fermentation microorganisms by adding a temperature control unit for setting the temperature of the fermentation tank in multiple stages to give optimum growth conditions according to the type of fermentation microorganisms input to ferment waste. By doing so, it can improve the reliability. In the present invention, the frequency of the AC 220V commercial power source in the Republic of Korea is 60Hz, the frequency of the AC 220V commercial power source in Japan is 50Hz to prevent malfunction of the system that may be caused by different frequency bands of commercial power in each country. This prevents commercial power from responding to exports to other countries.
