Then, the switch operation unit 201a operates on or off. And when the user releases the pressing state of the button 201e, the magnetic body 201d is returned to the initial position by the elastic member 201c. Therefore, the main operation switch 201 can operate continuously.

The main operation switch 201 applied to the embodiment of the present invention is an operation switch for operating the food waste disposer, and may be installed without cutting or penetrating the sink plate 202 . The main operation switch 201 of the present invention can be easily installed without damage such as drilling a hole in an existing sink, thereby reducing the number of installation work.

The main operation switch 201 normally operates the food processor through the control unit 400 . That is, when the main operation switch 201 is turned on, the control unit 400 receives the input signal of the main operation switch 201 and drives the main motor 601 for a predetermined time (for example, 2 minutes) and then stops make it And when the main operation switch 201 is operated once more in the ON state, the control unit 400 stops the main motor 601 by receiving the input signal thereof. And, when the main operation switch 201 is turned on, the control unit 400 does not operate the main motor 601 immediately, but after a certain time (for example, 2 seconds) elapses for the safety of the user, the main motor ( 601) is activated.

The body switch 211 is provided in the case C, as shown in FIG. 1 . The main body switch 211 includes a power switch 211a, a forward drive switch 211b, a reverse drive switch 211c, and an automatic cleaning switch 211d.

This is to solve a problem occurring in the food processor by rotating the motor 601 forward or reverse.

The forward drive switch 211b and the reverse drive switch 211c can be operated by manually pressing or releasing a pressing operation by the user. When the user presses the forward operation switch 211b or the reverse operation switch 211c, the main motor 601 drives in the forward or reverse direction after 2 seconds for safety, and the forward operation switch 211b or the reverse operation switch 211c is pressed. When the state is released, it is immediately stopped.

The automatic cleaning switch 211d transmits a signal to the control unit 400 to automatically clean the food processor to activate the self-cleaning mode.

The humidity sensor 221 is installed in the food processor to sense the humidity inside the drying bin and transmit it to the controller 400 . The drying bin installed in the food processor is a container in which food waste is crushed and compressed and temporarily stored for drying. That is, the humidity sensor 221 senses the humidity of the food waste that is crushed, compressed, and accommodated in the drying bin, and transmits it to the control unit 400 .

The overload processing unit 401 is a program module for performing a safety mode by detecting an input signal for overload from the overload detection sensor 261 . In the safe mode, the forward and reverse rotation of the main motor 601 may be performed one or more times, the buzzer 621 may be operated, and the LED lamp 631 may be turned on at the same time.

The drying mode processing unit 411 is a program module for drying the food waste that is crushed and compressed by the food processor and accommodated in the drying bin. The drying mode processing unit 411 is a program module for drying the food waste by controlling the BLDC motor 611 for blowing until the set value is satisfied according to the input value of the humidity sensor 221 .

The self-cleaning mode processing unit 421 is a program module that performs a control of self-cleaning the food processor when the number of times of food processing is equal to or greater than a certain number (eg, 5 times) or when the automatic cleaning switch 211d is input.

The self-cleaning mode processing unit 421, for example, when an input signal of the automatic cleaning switch 211d is input, stops the main motor 601 after forward driving (forward rotation driving) for a set time, and stops the main motor 601 . Reverse driving (reverse rotation driving) for a set time, performing this process a set number of times, and ending. Of course, in some cases, a user may supply water to the hopper 19 of the food processor. In this process, the food processor may be cleaned by itself.

The main motor 601 is driven under the control of the controller 400 to crush the food waste in the crusher 5 . The main motor 601 may be controlled by the control unit 400 for forward and reverse driving and rotational speed. The BLDC motor 611 for blowing is a motor driven when the drying mode is performed under the control of the controller 400 . The buzzer 621 and the LED lamp 631 may be driven by the controller 400 to inform the user of the state of the food processor aurally or visually.

A control method of the food processor control system configured as described above will be described with reference to FIGS. 10 to 13 .

The user operates the main operation switch 201 in the on state (S1) of the power switch 211a. Then, the control unit 400 controls the BLDC motor 611 for blowing to operate in an already set medium speed mode (S3). When the BLDC motor 611 for blowing is set to the low speed mode in the on state of the power switch 211a, it operates in the low speed mode.

If the user continuously presses the main operation switch 201, the on state of the main operation switch 201 is input to the control unit 400 (S5). Then, the main motor 601 is driven in the forward direction after a set standby time (S7). ). At this time, the standby time of the main motor 601 is suitable for about 2 seconds. And the driving time of the main motor 601 is suitable for about 2 minutes.

The overload processing unit 401 of the control unit 400 determines whether a normal signal for overload is input when the main motor 601 is driven by the overload detection sensor 261 (S9).

At this time, if a normal signal for overload is not input in step S9 of determining whether a normal signal for overload of the main motor 601 is input, the overload processing unit 401 of the control unit 400 controls the main motor 601 . is determined to be an overload state, and a safety mode is performed (S11).

After performing the safety mode (S11), the control unit 400 stops the main motor 601 (S23) and ends.

In the safe mode (S11), as shown in FIG. 13, the forward and reverse rotation driving of the main motor 601 is driven a set number of times (for example, once) (S111), the buzzer 621 is sounded, , the LED lamp 631 is turned on (S113).

Subsequently, when the normal load signal of the main motor 601 is input in step S9 of determining whether a normal signal for overload of the main motor 601 is input, whether the main operation switch 201 is input to an OFF state to determine (S13)

When the OFF signal of the main operation switch 201 is input to the control unit 400, the main motor 601 is stopped (S15). And the control unit 400 performs a drying function (S17).

The drying function ( S17 ) is performed by the drying mode processing unit 411 of the control unit 400 . The drying mode processing unit 411 of the control unit 400 loads the blower high-speed mode operation time (S171). The blower high-speed mode operating time can be set, for example, to 2 hours. And the humidity sensor 221 loads the first humidity value already set (S173). When the humidity sensor 221 senses the humidity inside the drying bin becomes the first humidity value, the drying mode processing unit 411 of the control unit 400 changes the BLDC motor 611 for blowing from the medium speed mode to the low speed mode. can control.

And the humidity sensor 221 loads the already set second humidity value (S175). When the humidity sensor 221 senses the humidity inside the drying bin satisfies the second humidity value, the drying mode processing unit 411 of the control unit 400 stops the BLDC motor 611 for blowing, which was driven at low speed. can take control

The first humidity value may be set higher than the second humidity value.

After the drying mode processing unit 411 of the control unit 400 loads the first humidity value and the second humidity value, the BLDC motor 611 for blowing is operated at high speed. Subsequently, the drying mode processing unit 411 of the control unit 400 determines whether the high-speed mode setting time is satisfied (S179).

When the drying mode processing unit 411 of the control unit 400 satisfies the set time, the blower BLDC motor 611 is controlled in the medium speed mode (S181), and if the set time is not satisfied, the blower operation step (S177) returns to before Goes.

Subsequently, the drying mode processing unit 411 of the control unit 400 receives the humidity value inside the drying bin from the humidity sensor 221 (S143). The drying mode processing unit 411 of the control unit 400 determines whether the sensing value of the humidity sensor 221 satisfies the first humidity value (S185). When the sensing value of the humidity sensor 221 satisfies the first humidity value, the drying mode processing unit 411 of the control unit 400 controls the blowing BLDC motor 611 in a low speed mode (S187). If the sensing value of the humidity sensor 221 does not satisfy the first humidity value, the drying mode processing unit 411 of the control unit 400 goes to before the step S181 of controlling the blower in the medium speed mode and drives the blower in the medium speed mode. .

Subsequently, the drying mode processing unit 411 of the control unit 400 determines whether the sensing value of the humidity sensor 221 satisfies the second humidity value (S189). When the sensing value of the humidity sensor 221 satisfies the second humidity value, the drying mode processing unit 411 of the control unit 400 performs control to stop the BLDC motor 611 for blowing (S191). If the sensing value of the humidity sensor 221 does not satisfy the second humidity value, the drying mode processing unit 411 of the control unit 400 goes to before the step (S187) of controlling the blower in the medium speed mode and drives the blower in the medium speed mode. .

After performing the drying function, the control unit 400 determines whether the number of times of food processing input to the control unit 400 is equal to or greater than a set value (S19). The number of times of food processing is counted by the number of operations of the main operation switch 201 and a preset value is set in the control unit 400 in advance. For example, the set value of the number of operations of the main operation switch 201 may be set to 5 times.

If the number of times of operation of the main operation switch 201 satisfies the set value, the self-cleaning mode is performed (S21).

The self-cleaning mode is performed ( S21 ) by the self-cleaning mode processing unit 421 of the control unit 400 , as shown in FIG. 12 . That is, the self-cleaning mode processing unit 421 of the control unit 400 stops the main motor 601 after driving in the forward direction for a set time (S211). At this time, the set time for the forward driving of the main motor 601 is preferably 15 seconds.

Then, the forward driving of the main motor 601 is stopped, and after 10 seconds, the self-cleaning mode processing unit 421 of the control unit 400 continuously drives the main motor 601 in the reverse direction for a set time and then stops (S213). At this time, the set time for the reverse driving of the main motor 601 is preferably 15 seconds.

The self-cleaning mode processing unit 421 of the control unit 400 determines whether the number of repetitions set is satisfied (S215). The self-cleaning mode processing unit 421 of the control unit 400 ends the control of the main motor 601 when the set number of times is satisfied. The set number of repetitions processed by the self-cleaning mode processing unit 421 may be set to, for example, 5 times.

The first proximity sensor 231 and the second proximity sensor 241 may additionally perform a safe mode.

The first proximity sensor 231 and the second proximity sensor 241 detect the amount of food to be dried in the drying bin and transmit it to the control unit 400 . Then, the control unit 400 determines that there is an excessive amount of food waste in the drying bin, and drives the buzzer 621 or the LED lamp 631 so that the user can check it.

In addition, the locking sensor 251 detects when the drying bin is detached without being inserted into the proper position and transmits it to the control unit 400 . Then, the control unit 400 can control to drive the buzzer 621 and turn on the LED lamp 631 . The control unit 400 that has received the detection signal of the locking sensor 251 may perform a function to prevent odor leakage in the drying bin when the drying bin is removed.

On the other hand, if the user presses the power switch 211a of the main body switch 211 for a set time or longer, the program of the control unit 400 may be initialized.

As described above, the present invention introduces natural wind (at room temperature) from the outside into the inside of the drying bin to dry the food waste in the drying bin in a vortex method, thereby shortening the drying time and thus reducing the overall processing time of the food waste, thereby improving the marketability. have.

In particular, according to the present invention, food waste discharged through cutting, dehydration, and compression processes increases the surface area by cutting and the average moisture content of the food waste decreases due to the removal of moisture, so that it can be easily dried even in natural wind, It can satisfy related environmental certification regulations.

In addition, the present invention can maintain a comfortable environment by suppressing odors generated in the process of food waste treatment through a system and control for discharging the entire amount of internal air of the food waste treatment system through an outlet (sewer).

In addition, the present invention can save energy by minimizing power consumption through the control of operating or stopping the blower at medium or low speed depending on the humidity state of the drying bin.
