Done.

And the shaft insertion hole 116 through which the stirring shaft 134a to be described below is inserted into the left and right sides of the decomposition tank 100 is formed through. That is, the first shaft insertion hole 116 ′ through which both ends of the first stirring shaft 134a ′, which will be described below, are inserted and formed in the first half side of the disassembling tank 100, the decomposition tank 100 A second shaft insertion hole 116 ″ through which both ends of the second stirring shaft 134a ″ to be described below are inserted is formed in the second half of the side.

The lower side of the decomposition tank 100 is provided with a base fan 120 to form a lower appearance. The base fan 120 is formed of a square flat plate corresponding to the bottom size of the outer casing 10, a plurality of parts are fixedly installed on the upper surface of the base fan 120.

The base pan 120 and the disassembling tank 100 is preferably installed at a predetermined interval, the disassembling tank 100 is supported by a plurality of support (122). The support 122 is composed of a frame having a predetermined size, and is installed at four corners of the disassembling tank 100. Therefore, the lower ends of the four supports 122 are in contact with the base pan 120, and the upper ends of the supports 122 are in contact with the disassembling tank 100 so that the disassembling tank 100 is fixed.

The stirring means, a pair of shaft assembly 134 for mixing the food in the decomposition tank 100 by rotating by the power supplied from the stirring motor 132 and the stirring motor 132 to generate a rotational power ), And a connecting member 136 for transmitting power generated by the stirring motor 132 to the pair of shaft assemblies 134.

The stirring motor 132 is fixed to the upper surface of the base fan 120 to generate a rotational power by the power supplied from the outside. Therefore, the rotational power generated by the stirring motor 132 is transmitted to the connecting member 136 to be described below through the motor pulley 132 'protruding from one side of the stirring motor 132, the shaft assembly 134 ) To rotate.

The shaft assembly 134 is provided with a stirring shaft 134a installed across the decomposition tank 100 and one end of the stirring shaft 134a, and a shaft pulley 134b on which the connecting member 136 is caught. And a plurality of stirring blades 134c installed on the outer surface of the stirring shaft 134a to mix the food in the decomposition tank 100.

The shaft assembly 134 is provided with a pair as described above. In more detail, the first shaft assembly 134 ′ and the second shaft assembly 134 ′ which are relatively installed at the front are divided into two parts. 100 is positioned above the first accommodating part 102 ', and the second shaft assembly 134 " is located above the second accommodating part 102 "

The pair of shaft assemblies 134 are installed at different installation heights. That is, the first axis assembly 134 ′ is installed at a position relatively lower than the second axis assembly 134 ″.

The stirring shaft 134a and the shaft pulley 134b are also formed on the first shaft assembly 134 ', the first stirring shaft 134a' and the first shaft pulley 134b ', and the second shaft. It is divided into a second stirring shaft 134a "and a second shaft pulley 134b" formed in the assembly 134 ". Therefore, both ends of the first stirring shaft 134a 'are formed in the first shaft insertion hole 116. '), And both ends of the second stirring shaft 134a "are inserted into the second shaft insertion hole 116".

The stirring blade 134c is formed to have a constant twist angle with respect to the stirring shaft 134a. The reason why the stirring blade 134c is formed to have a torsion angle with respect to the stirring shaft 134a is to reduce the load caused by the food and ceramic balls 160 when the shaft assembly 134 is rotated.

The connection member 136 is preferably made of a chain (chain). Accordingly, the shaft pulley 134b and the motor pulley 132 ′ are preferably made of a chain pulley on which a chain is applied. The connection member 136 is made of a chain as described above, in order to prevent slipping and to transmit power more accurately.

The connecting member 136 should always maintain a suitable tension (tension), the tension (tension) of the connecting member 136 is adjusted by the tension adjusting means 150. The tension control means 150 is composed of an adjustment pulley 152 to which the connecting member 136 is caught, an adjustment lever 154 forcing the movement of the adjustment pulley 152, and the like.

More specifically, the control pulley 152 is protruded to the left side on the left side of the decomposition tank 100. And in front of the control pulley 152 is provided an adjustment lever 154 forcing the control pulley 152 to move back and forth. The control lever 154 is preferably made of a bolt-nut coupling.

Therefore, when the user turns the bolt of the adjustment lever 154 clockwise, the adjustment pulley 152 is moved to the rear to increase the tension of the connecting member 136, conversely the user of the control lever 154 When the bolt is turned counterclockwise, the adjusting pulley 152 moves forward to reduce the tension of the connecting member 136.

The extinguishing means includes microorganisms (not shown) for decomposing food, and ceramic balls 160 inhabiting a plurality of micropores formed therein. And the ceramic ball 160 is mixed with food by the stirring means.

The ceramic ball 160 is provided in the lower side of the decomposition tank 100, a number is preferably provided to occupy about 1/5 ~ 1/6 of the space inside the decomposition tank 100. Thus, the ceramic ball 160 to occupy about 10 to 20% of the volume of the decomposition tank 100, if the amount of the ceramic ball 160 is too large, a lot of load acts on the stirring means and the stirring motor This is because excessive force is applied to the 132, and if the amount of the ceramic ball 160 is too small, the amount of microorganisms is so small that the decomposition rate of food is slow.

The ceramic ball 160 is made of bio (ceramic), and has a sufficient durability because a plurality of them are mixed with the food by the stirring blade 134c. More preferably, the compressive strength is made of ceramics of about 10Kg / cm 2 to about 200Kg / cm 2.

As such, the reason for limiting the compressive strength of the ceramic ball 160 is that if the compressive strength is too low, the ceramic ball 160 may be easily worn, and it is difficult to crush food having a relatively high strength, and if the compressive strength is too high, the ceramic This is because the stirring blade 134c for stirring the ball 160 and the surface of the decomposition tank 100 may be damaged.

The ceramic ball 160 is formed to have a size of about 8 ~ 20mm outer diameter. In this way, the size of the ceramic ball 160 is limited in order to simultaneously consider the efficiency of crushing food by the ceramic ball 160 and oxygen supply efficiency of microorganisms inhabiting the ceramic ball 160.

More specifically, when the size of the ceramic ball 160 is larger than 20mm, the grinding force of the food falls. That is, the plurality of ceramic balls 160 is also mixed with food and serves to finely crush the sound plant, the larger the size of the ceramic ball 160, the voids between the ceramic balls 160 is too large, the grinding force of the food This is because it is degraded.

In addition, when the size of the ceramic ball 160 is 8mm or less, the voids between the ceramic balls 160 is too small, it is difficult to supply sufficient oxygen to the microorganisms inhabiting the ceramic ball 160.

A plurality of fine holes are formed in the ceramic ball 160 to provide a passage through which microorganisms can inhabit and move. The micropores are formed to have a size (diameter) of about 1.0 to 2.0 mu m. This takes into account that the size of the bacteria described below is about 0.5 ~ 1.5㎛.

For example, when the size of the micropores formed in the ceramic ball 160 is less than or equal to 1.0 μm, the microorganisms (bacteria, etc.) are inhabited narrowly. This is because the ability to inhabit, etc. decreases.

Various kinds of bacteria may be used as the microorganisms inhabiting the ceramic ball 160, but the case where bacteria are used as an example will be described as an example. Bacteria are the smallest and inferior microorganisms in which the body consists of a single cell. To date, more than 2,000 species are known, and because they do not have chlorophyll, photosynthesis is impossible. Therefore, if there is nutrients in the ground, in the water, in the air, or in the body of a person, parasitics occur.

To grow, these bacteria need the right temperature, humidity, and oxygen along with nutrients. Growing well below 20 ℃ is called low temperature, growing well at 55 ~ 60 ℃ is called high temperature, and growing at mid temperature is called mesophilic. And bacteria that require oxygen are aerobic, bacteria that can live without oxygen are called anaerobic.

The ceramic ball 160 is preferably mixed with various bacteria as described above. However, for convenience of explanation, hereinafter, the case where high temperature and aerobic bacteria are used will be described as an example. Various bacteria as described above are sucked by vacuum suction inside the ceramic ball 160.

The water supply means includes a water supply pipe 172 for guiding water introduced from the outside, and a water supply valve 174 installed in the water supply pipe 172 to selectively shield the water supply pipe 172. It is provided at the end of the water supply pipe 172 is composed of a spray nozzle 176 or the like for spraying water.

The water supply pipe 172 is formed up and down on the right outside of the decomposition tank 100, to guide the water supplied from the outside through the water pipe 220 to be described below to the injection nozzle 176. The water supply valve 174 is provided at the lower end of the water supply pipe 172, and opens and closes the water supply pipe 172 by the command of the control means. The water supply valve 174 is preferably made of a solenoid valve.

The injection nozzle 176 is installed at the upper end of the decomposition tank 100, it is configured to spray the water downward. That is, the upper end of the water supply pipe 172 is vertically bent to extend into the decomposition tank 100, the injection nozzle 176 is formed at the end of the water supply pipe 172.

The water supply means is configured to supply water to the extinguishing means under control of the control means even when the stirring means is not operated. That is, even when all the food is consumed in the decomposition tank 100 and the stirring means is stopped, water is supplied into the decomposition tank 100 by the water supply means.

The reason why the water supply means is operated even when the food is not processed as described above is to provide an environment in which microorganisms inhabit the ceramic balls 160 provided in the decomposition tank 100. That is, the water supply means supplies water to the decomposition tank 100 so that the food in the decomposition tank 100 is mixed smoothly and at the same time provides moisture to the microorganisms inhabiting the ceramic ball 160. It is to play a role.

Therefore, although not shown, a separate humidity sensor is provided to transmit the current humidity state of the current decomposition tank 100 to the control means, the control means is also configured to control the water supply means based on this information. It will be possible.

The forced exhaust means is a forced exhaust pipe 182 for guiding the gas (odor) in the decomposition tank 100 to the outside, and the suction fan is provided on one side of the forced exhaust pipe 182 to generate a suction force ( 184).

In addition, the forced exhaust pipe 182 is installed so that the upper end is in communication with the inner upper portion of the decomposition tank 100, the lower end is installed so as to communicate with the sewer pipe 204 to be described below.

As described above, the forced exhaust means discharges food decomposition gas in the decomposition tank 100 to the outside and supplies oxygen to the microorganisms (bacteria) inhabiting the ceramic balls 160. do. That is, when the air inside the decomposition tank 100 escapes to the outside, oxygen is supplied to the ceramic ball 160 because new external air flows into the decomposition tank 100. Therefore, the forced exhaust means is set to continue to operate even when the apparatus is stopped to supply oxygen to the microorganisms of the ceramic ball 160.

The heater 190 is installed at the lower end of the decomposition tank 100, and selectively operates according to the internal temperature of the decomposition tank 100. In more detail, a heater 190 is attached to the bottom of the accommodating part 102, and a temperature sensor (not shown) for measuring an internal temperature is installed at the decomposition tank 100. The temperature information detected by this is transmitted to the control means.

Therefore, when the temperature measured by the temperature sensor is less than the predetermined temperature, the control means to heat the heater 190 to increase the temperature inside the decomposition tank (100). When the temperature of the decomposition tank 100 rises to the set temperature, the heater 190 is turned off.

For example, the control means to operate the heater 190 when the temperature inside the decomposition tank 100 measured by the temperature sensor is 20 ℃ or less, when the temperature inside the decomposition tank 100 is 60 ℃ or more The heater 190 is controlled to be off.

As such, maintaining the temperature inside the decomposition tank 100 within a predetermined range is to speed up decomposition of food by maintaining a temperature at which microorganisms (bacteria) inhabiting the ceramic ball 160 are active.

A plurality of slits S are formed at the lower right side of the front side of the decomposition tank 100. That is, a plurality of slits S are formed through the vicinity of the front right end of the first accommodating part 102 ′.

The slit S is a portion through which water inside the decomposition tank 100 passes. That is, water separated from the food or decomposed food is discharged to the outside through the slit (S). Therefore, the width of the slit S is preferably formed to have a size of about 0.5 to 2.0mm.

A water collecting tank 200 is installed at the lower end of the decomposition tank 100. More specifically, the sump 200 is installed below the plurality of slits S formed in the first accommodating portion 102 ′ of the disintegration tank 100. Therefore, the water contained in the food inside the decomposition tank 100 is separated and passed through the slit (S), and then collected in the sump (200).

On the other hand, although not shown, the shaft assembly 134 may be further provided with a brush for cleaning the slit (S). That is, a brush is further provided on the stirring blade 134c of the shaft assembly 134 to contact the slit S while the shaft assembly 134 rotates to separate food attached to the slit S, and thus the slit S ) Is sealed.

The discharge pipe 202 is connected to the bottom of the sump 200. The discharge pipe 202 is a pipe for guiding the discharge of sewage collected in the sump 200, this discharge pipe 202 is in communication with the sewer pipe (204). The sewer pipe 204 is installed on the upper side of the base pan 120 to guide the water accumulated in the sump 200 to be discharged to the outside.

The sewer pipe 204 is further provided with a backflow prevention means (206). The non-return means 206 serves to block the sewage when the sewage flows back through the sewer pipe 204 due to the blockage of the sewer main pipe (not shown), and includes a check valve. In addition, when the non-return means 206 is operated by the reverse flow of sewage, this state is displayed to be recognized by the user through the display unit 244, which will be described below, while a buzzer (not shown) is shown. And a warning sound).

In addition, as described above, the sewer pipe 204 is also connected to the forced exhaust pipe 182. Therefore, the sewage of the sump 200 in the sewage pipe 204 and the odor discharged through the forced exhaust pipe 182 is mixed and discharged to the outside.

The sump 200 is further connected to the wash water pipe 210. The washing water pipe 210 is to wash the inside of the sump 200 by guiding the water introduced through the water pipe 220 to be described below to the sump 200, and the washing water pipe 210 is the washing water It is opened and closed by the valve 212.

Hereinafter, a control method of the food waste treatment apparatus according to the present invention having the above configuration will be described.

As shown in the block diagram in Figure 6, the control method according to the present invention, whether the plant waste is put into the decomposition tank 100 is accommodated in the plurality of ceramic balls 160 in which the microorganisms inhabit When the food waste detection step 300 to determine whether, and the food waste is put into the decomposition tank 100, the food waste and the ceramic ball 160 are mixed with each other to stir and inhabits the ceramic ball 160 Stirring and decomposition step 310 to decompose food using microbial bacteria, and if food waste is not put into the decomposition tank 100 for a predetermined time or more can survive in the microorganisms inhabiting the ceramic ball 160 The microorganism management step 320 to provide an environment is largely divided.

In more detail, first, a plurality of ceramic balls 160 are introduced into the decomposition tank 100. That is, the user removes the upper surface 20 and peels off the upper cover 106, and then, a plurality of ceramic balls 160 are input through the upper opening 104 ′, and the ceramic balls 160 are inside the ceramic ball 160. There are a number of microorganisms (bacteria) such as bacteria are inhabited by vacuum adsorption.

In addition, the control means provided in the control box 240 is a state in which the overall operating state of the food waste processing apparatus is set in advance. Therefore, when the user turns on the power switch 250, the food waste processing apparatus is ready for operation and the food detection step 300 is started.

In the food detection step 300, the food waste is directly detected through the external inlet 22, the input state into the decomposition tank 100, or the inlet door 24 to shield the external inlet 22 ) Is the step of judging whether food waste is input or not by detecting the opening of the food waste.

Here, looking at the example of determining whether the food is put in accordance with the opening of the inlet door 24, when the user opens the inlet door 24, the door sensor 26 of the inlet door 24 Detects the opening and transmits this state to the control means, and the control means transmits a control command to the water supply means including the stirring means, the forced exhaust means, and the heater 190.

When food is introduced into the decomposition tank 100, the stirring and decomposition step 310 is performed. In the stirring and decomposition step 310, the ceramic ball 160 and the food waste, which are accommodated in the decomposition tank 100, are mixed with each other, and the food is decomposed by the microorganism.

In more detail, the stirring means is operated to mix the food and the ceramic ball 160 introduced into the decomposition tank 100 with each other. That is, the stirring motor 132 is operated by the power transmitted from the outside, the rotation of the stirring motor 132 is transmitted to the shaft assembly 134 by the connecting member 136. Therefore, the food and ceramic balls 160 are mixed with each other by the stirring blade 134c.

That is, as the shaft assembly 134 is rotated, the ceramic ball 160 is pushed up by the stirring blade 134c to rise and fall along the inner surface of the disassembling tank 100 and continuously repeats the movement. As the ceramic ball 160 is mixed with food waste, the food waste is crushed.

At the same time, microorganisms (bacteria) inhabiting the ceramic ball 160 come out along the micropores to decompose food waste.

On the other hand, the user operates the control lever 154 of the tension adjusting means 150, so that the transmission of power is made smoothly by adjusting the tension of the connection member 136.

In addition, the stirring and decomposition step 310, the forced exhaust process (312) for discharging the odor (carbonate gas) generated in the decomposition tank 100 to the outside, and the temperature inside the decomposition tank 100 Temperature maintenance process 314 to maintain within a certain range, and a water supply process 316 for supplying moisture into the decomposition tank 100 is further included.

The forced exhaust process 312 is a step of discharging the odor (carbonate gas) in the decomposition tank 100 to the outside by the forced exhaust means, the external fresh air flows into the decomposition tank 100. to be.

Therefore, at this time, the suction fan 184 is operated, the gas inside the decomposition tank 100 is discharged to the forced exhaust pipe 182 by the suction force generated by the operation of the suction fan 184. . That is, odor generated when the food in the decomposition tank 100 is decomposed is discharged to the sewer pipe 204 through the forced exhaust pipe 182.

The temperature maintenance process 314 is a process of maintaining the temperature inside the decomposition tank 100 to 20 ℃ ~ 60 ℃ set temperature range by the selective use of the heater 190. Of course, the set temperature range may be variously changed according to the user's setting.

More specifically, the information measured by the temperature sensor (not shown) for measuring the temperature inside the decomposition tank 100 is transmitted to the control means, the control means analyzes the information is set to a temperature (20 ℃) ) Or less, the heater 190 is operated.

The control means analyzes the information transmitted from the temperature sensor, and stops the operation of the heater 190 when the temperature inside the decomposition tank 100 exceeds a set temperature (60 ° C.).

The water supply process 316 is a process of supplying a predetermined amount of water every time set in the decomposition tank 100. Of course, the water supply process 316 may be configured to supply water when the humidity is lower than the set humidity range by measuring the humidity in the decomposition tank 100 in addition to the method of supplying a predetermined amount of water every set time. have.

As such, in the water supply process 316, the water supply means supplies water into the decomposition tank 100 according to a preset program. That is, when the water supply valve 174 is opened according to the command of the control means, water is injected through the injection nozzle 176 to supply sufficient water to the food and the ceramic ball 160.

By the forced exhaust process 312, the temperature maintenance process 314 and the water supply process 316, etc. inside the decomposition tank 100 has a humidity and temperature to facilitate the decomposition of food and microbial bacteria, The decomposition of food is promoted.

The forced exhaust process 312, the temperature maintaining process 314, and the water supply process 316 are operated immediately when the power switch 250 is turned on regardless of whether food waste is input. Preferably, the inside of the decomposition tank 100 is controlled by the control means so as to be an appropriate environment (environment with sufficient oxygen, temperature and humidity) for food decomposition.

Moisture contained in the food introduced into the decomposition tank 100, and water (H ₂ O) generated by the food is broken is flowed from the receiving portion 102 by the stirring blade 134c and the slit ( Pass S) and exit outside.

The water exiting the slit S is accumulated in the sump 200, and the water in the sump 200 passes through the discharge pipe 202 and is discharged to the sewage pipe 204. The sewage pipe 204 is mixed with the water discharged from the sump 200 and the gas (odor) discharged through the forced exhaust pipe 182 is discharged to the outside.

The washing water valve 212 is opened every predetermined time according to the command of the control means. That is, the washing water valve 212 at the time set by the user to open the washing water pipe 210, so that water is injected into the sump (200). In addition, the washing water valve 212 is opened when it is necessary to dilute the sewage drained to the outside through the discharge pipe 202 as described above.

Water sprayed into the sump 200 removes the foreign matter attached to the sump 200 and the food blocking the slit S. In this case, the fine foreign matter in the sump 200 is washed with water and discharged to the discharge pipe 202, the slit (S) is opened so that the water in the decomposition tank 100 is the sump 200 Is discharged smoothly.

The stirring means is operated for a set time. That is, after the food is introduced into the decomposition tank 100, after a predetermined time (for example, 5 hours, etc.) has passed, the operation of the stirring means is stopped.

Of course, it is also possible to set the stirring means to stop when the food is completely extinguished by detecting whether food is left inside the decomposition tank 100 without uniformly stopping the stirring means after a predetermined time. will be.

In addition, since the control box 240 has a built-in charging battery (not shown) for supplying power to the control means, the power switch 250 is turned off (off), the entire apparatus is paused. When it is operated again, the control means stores the remaining time and controls the apparatus to operate for the remaining time. The remaining time is displayed to the outside through the display unit 244.

If the above process continues, the food present in the digestion tank 100 is gradually crushed, about 30 minutes to 1 hour, the shape of the food is crushed so as not to recognize, about 4 to 5 hours After this, about 90% of the food waste is destroyed.

When the food is extinguished, food decomposition gas such as ammonia or methane gas and water (H ₂ O) are produced, and this food decomposition gas is discharged to the outside by the forced exhaust means, and the water (H ₂ O) is It is discharged to the outside through the discharge pipe 202 and the discharge pipe 202 and the sewage pipe 204.

On the other hand, when food waste is not put into the digestion tank 100 for a predetermined time (for example, 7 hours, etc.), it provides a viable environment for microorganisms (bacteria) inhabiting the ceramic ball 160. Microbial management step 320 is performed.

The microorganism management step 320, the water supply process 316 for supplying water to the microorganisms (bacteria) inhabit the ceramic ball 160, and the microorganisms (bacteria) inhabit the ceramic ball 160 Forced exhaust process (312) for supplying oxygen to) and nutrient supply process (322) for supplying nutrients to the microorganisms (bacteria) inhabiting the ceramic ball (160).

As described above, the water supply process 316 is a process of supplying water to the decomposition tank 100 by the water supply means every predetermined time. Therefore, the water supply process 316 proceeds regardless of whether or not food waste is put into the decomposition tank 100. Of course, when the food is introduced into the decomposition tank 100 and the water supply when not added will be adjusted differently.

As described above, the forced exhaust process 312 also by forcibly discharging the air (odor) inside the decomposition tank 100 by the forced exhaust means to the outside, the outside air inside the decomposition tank 100 It is the process to make it flow into.

As such, the forced exhaust process 312 removes odors (carbonic acid, etc.) inside the decomposition tank 100, and serves to provide oxygen to the microorganisms inhabiting the ceramic ball 160. It is preferable that the food is always operated regardless of whether food is introduced into the decomposition tank 100 or whether the stirring means is operated.

The nutrient supply process 322 is a process of supplying the nutrient 262 to the microorganisms (bacteria) inhabiting the ceramic ball 160 by the nutrient supply means 260 as shown in FIG. As described above, as the nutrient 262, bacterial stock solution is used. Of course, the nutrients 262 supplied by the nutrition supply process 322 is supplied in a predetermined amount every predetermined time according to the user's setting.

Looking in more detail, the nutrient control valve 270 is opened according to a program set in the control means, the nutrient 262 is injected into the decomposition tank 100 through the nutrient injection nozzle 268. . As such, the feeding process 322 is used only when the device is not operated for a long time. That is, since the food is stored inside the digestion tank 100 while the apparatus is in use, the microorganisms (bacteria) inhabiting the ceramic balls 160 can separate the food and absorb nutrients so that the external Because you do not need to provide for zero.

In addition, after the stirring and decomposition step 310, a suspended matter removing step 330 for removing the suspended matter in the drainage sewage with microorganisms (bacteria) is further provided. That is, in the case where the suspended matter decomposing means 280 as shown in FIG. 5 is further installed, the suspended matter removing step 330 in which the wastewater passing through the sewer pipe 204 is once again purified is performed.

At this time, the suspended matter (dish washing oil, etc.) introduced into the sump (284) through the sewer pipe (204) is floated on the water (286) accumulated in the sump (284), the float is the floating ceramic ball ( 282) It is degraded by microorganisms (bacteria, etc.) that live therein.

As the drainage is gradually collected into the sump 284, and the height of the water 286 is higher than the upper end of the sewer pipe 290, the water in the sump 284 naturally overflows. Sewage pipe 290 is introduced.

In addition, when the sewer main pipe (not shown) is blocked and the backflow occurs in the sewer pipe 204 or the sewer pipe 290, the backflow prevention means 206 operates to prevent the backflow of the sewage, while the display unit ( A buzzer (not shown) is displayed at the same time as the display through 244 to allow the user to visually and audibly detect the backflow of the sewage and take appropriate measures.

In addition, when an error occurs during the operation of the food waste treatment apparatus as described above, the operation of the apparatus is automatically stopped, and such an error occurrence state is displayed to the outside so that the user can recognize it. This is preferred.

More specifically, when an error occurs, the control means detects this, causing the stirring and disassembly step 310 to stop automatically, and generates an alarm to the outside. That is, the display unit 244 indicates that an error has occurred, and a buzzer (not shown) is sounded to allow the user to sense an error occurrence audibly.

The scope of the present invention is not limited to the above-exemplified embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the above technical scope.

In the above embodiment, the door sensor 26 detects the inlet door 24 in order to detect that the food is input, but in addition to this configuration, the food directly input through the external inlet 22 is directly detected. Of course, it is also possible to install and use a sensor. That is, by installing an infrared sensor in the external inlet 22 to detect whether or not food passes through the external inlet 22, it is also possible to configure such that the detection result is transmitted to the control means.

According to the control method of the food waste treatment apparatus of the present invention as described above, the stirring and decomposition step of decomposing while stirring the food according to the input of food waste, and the microbial management step of providing an environment in which microorganisms can survive Is activated. As described above, according to the present invention, since each step is automatically selected and operated according to whether the food is added, there is an advantage in that the processing of food waste becomes more convenient.

In addition, each process (oxygen, moisture, nutrition, etc.) is automatically operated to create a good environment for microbial bacteria, regardless of whether food is put in or out, so that the long-term use of microbial bacteria is possible, thereby reducing costs. There is an advantage that the ease of use is improved.
