Description

Stirring Operation Method of Food Waste Disposer

The present invention relates to a stirring operation method of the food waste treatment machine, and more particularly, when the stirring motor is constrained in the process of performing the stirring operation to mix the food waste introduced into the fermentation tank with the fermentation aid, the cause of restraint is precisely determined. To identify and inform the user.

In general, the food waste disposal device is a device for processing only food waste among household waste generated at home, and the demand is increasing gradually due to the efforts of housewives to reduce the generation of waste according to the implementation of the waste-based system. In addition, related technologies are also developing.

In the food waste disposal system, a top cover 3 having an inlet 2 is fixed to an upper portion of the main body 1, and a lid 4 is rotatably installed on the top cover to open and close the inlet 2. In the main body 1, the fermentation tank 5 is fixed in communication with the inlet 2 of the top cover 3, and the driving force of the stirring motor 6 is transferred to the power transmission member within the fermentation tank. 7) The stirring blade 8 is installed to rotate through the transmission, and the heater 9 is installed on the outer lower surface of the fermenter 5 so as to generate heat by being supplied with power.

In addition, a communication hole 10 is formed at the rear of the upper end of the fermentation tank 5 so as to communicate the inside of the fermentation tank with the inside of the top cover 3, and an exhaust hole 11 is formed at the rear of the top cover 3. The exhaust fan 12 is provided near the exhaust hole 11 in the top cover 3.

Therefore, if the user puts the fermentation aid containing the fermentation microorganism into the fermentation tank (5) fixed inside the main body (1) and then maintain the temperature and humidity inside the fermentation tank at an appropriate state, the activity of the fermentation microorganism becomes active It breeds in the fermenter 5.

In such a state, the user opens the lid 4 rotatably installed on the top cover 3 of the upper part of the main body 1 to dispose of food waste to be treated in the state in which the opening 2 of the top cover 3 is opened. When the fermentation tank 5 is selected and the fermentation mode is selected, the stirring blade 8 installed in the fermentation tank receives the driving force of the stirring motor 6 through the power transmission member 7 and rotates the food waste injected into the fermentation aid. At the same time, since the heater 9 installed on the outer lower surface of the fermentation tank 5 generates heat to heat the fermentation tank 5, the food waste mixed with the fermentation aid as the inside of the fermentation tank maintains the set fermentation temperature. Is fermented by the fermentation microorganism, and if the fermentation is continued for a certain period of time is composted, the processing of food waste is completed.

On the other hand, when the food waste is fermented in the fermentation tank (5), since the exhaust fan 12 installed near the exhaust hole 11 in the top cover 3 is operated, air is discharged to the outside through the exhaust hole (11). At this time, the outside fresh air is sucked into the fermentation tank 5 through the intake hole (not shown) formed in the main body 1 due to the suction force due to the air discharge and at the same time the food waste is fermented in the fermentation tank. The odor gas generated by the air is discharged into the top cover 3 through the communication hole 10 formed in the upper rear of the fermentation tank 5 and discharged in accordance with the operation of the exhaust fan 12. 11) and the air discharged through the outside, wherein the odor component exiting through the exhaust hole passes through a deodorizer (not shown), so in this process a significant amount of odor gas is deodorized. 1 is external to the exhaust, only relatively clean air.

When the stirring operation, which is a process for mixing the food waste introduced into the fermentation tank with the fermentation aid, is performed in the above-described food waste processing machine, a foreign material is caught in the stirring wing 8 or the device is installed outdoors. When the food waste and fermentation aid in the fermentation tank (5) is frozen by the low temperature of the outside air in the confined state that the driving of the stirring motor (6) which rotates the stirring blade (8) is not made smoothly or completely driven In order to inform the user as to maintain the user to be able to solve the restraint state of the stirring motor 6, the conventional method of the stirring operation is the stirring blade (8) is rotated by the driving of the stirring motor (6) Performing stirring while sensing the state of restraint of the stirring motor 6 during the stirring; The half through the display notifies it to the user when the motor is constrained, the stirring step, the stirring was continued to carry out when the motor 6 has not been bound is carried out sequentially.

Therefore, when the stirring motor (6) is driven to rotate the stirring blade (8) in the fermentation tank (5), while the food waste introduced into the fermentation tank (5) is mixed with the fermentation aid, fermentation proceeds by the fermentation microorganisms, at this time The drive of the stirring motor 6 is slowed down more than necessary or the drive stops completely due to various factors (the stator blades are caught by foreign substances and the food waste and fermentation aids in the fermenter are frozen as the temperature of the outside air is lowered below the freezing point). In case of being in a restraint state, the controller recognizes the restraint state of the stirring motor 6 through a separate means, and if the restraint state of the stirring motor is sensed, regardless of the restraint factor of the stirring motor 6. Since the display unit informs the user, the user may be the cause of restraint of the stirring motor by restraining it from freezing or other factors. Taking out the in going state) is applied by taking an appropriate action accordingly.

Means for the controller to recognize the restraint state of the stirring motor 6 is to detect the rotational speed of the stirring motor using a generator or a hall sensor.

However, the conventional stirring operation method as described above informs the user only that the stirring motor is restrained regardless of the cause of the restraint when the stirring motor is restrained, so that the user knows that the stirring motor is once restrained. If you find the cause artificially and then solved the restraint state of the stirring motor accordingly, there was a very uncomfortable use.

The present invention has been made in order to solve the above-mentioned conventional problems, when the stirring motor is constrained in the course of the stirring operation to mix the food waste introduced into the fermentation tank with the fermentation aids to accurately determine the cause of restraint The purpose is to enable the user to quickly solve the cause of restraint of the stirring motor to inform the user.

According to the present invention for achieving the above object, the normal operation step of performing the stirring while the stirring blade is rotated by the drive of the stirring motor, and the restraint detection step of detecting the restraint state of the stirring motor during the stirring is performed; When the stirring motor is not constrained, the normal operation step is continued, and when the stirring motor is constrained, the driving of the stirring motor is stopped, and when the driving of the stirring motor is stopped, the restraint of the stirring motor is frozen. The restraint type judgment step of determining whether the restraint is by restraint or by freezing, and when the restraint of the stirring motor is judged to be restraining by freezing, a freeze restraining operation is performed. The food waste disposer in which the restraint release step is performed sequentially Stirring operation is provided.

Detecting a confined state of the motor, stopping the driving of the stirring motor 6 when the stirring motor is constrained, and continuing stirring when the stirring motor is not constrained, and of the stirring motor 6. When the stirring motor is stopped due to restraint, detecting the outside temperature and comparing the detected temperature value t with a preset set temperature value T, wherein the detected temperature value t is a set temperature value Than (T) If it is equal to or greater than one, it is determined that the procedure is based on freezing, and if the detected temperature value (t) is greater than the set temperature value (T), it is judged as restraint (general restraint) other than freezing. Performing steps are performed sequentially.

The algorithm when it is determined that the restraint is caused by the freezing is one embodiment.

If it is small, the step of returning to the initial state when the restraint of the stirring motor 6 is judged to be restrained by freezing, and the step of determining whether the driven stirring motor is restrained when the stirring motor 6 is driven. If the stirring motor is still constrained, the stirring motor from this time When the speed is counted, if the stirring motor 6 is not restrained, the process returns to normal stirring operation immediately, and when the number of restraints of the stirring motor 6 is counted, the number of restraint counts of the stirring motor is counted. t ₂₎ a group of input set count value (T ₂₎ and constraining the number of times the value of the phase with stirring in which the count motor (6) for comparison (t ₂₎ after the case is greater than or equal to the set count value (T ₂₎ While stopping all the processes of the stirring motor binding state by freezing is displayed on the display unit, if the number of times of restraint (t ₂ ) of the counting stirring motor (6) is less than the set number of times (T ₂ ) stirring motor ( The step of returning to the initial state when the restraint of 6) is judged to be restraint by freezing is sequentially performed.

The step of returning to, and if the stirring motor (6) is driven to determine whether the driven stirring motor is constrained, and if the stirring motor is still constrained, the stirring motor restraint time from this time is counted, stirring motor (6) is not bound , The redemption time value of the count stirring motor (t _3), the group added set time value when the step goes back to the straight normal stirring operation, a restraint time of the stirring motor 6 is counted when the (T ₃₎ Comparing with the step, and if the restraint time value (t ₃ ) of the counting stirring motor 6 is greater than or equal to the set time value (T ₃ ) all the subsequent processes are stopped and the stirring motor binding state by freezing When the restraint time value t ₃ of the stirring motor 6 that is displayed through the display unit and counted is smaller than the set time value T ₃ , the restraint of the stirring motor 6 is determined to be restraint by freezing. Returning to the initial state is performed sequentially.

In addition, the algorithm when it is determined that the restraint other than the freezing is an embodiment, and turns on the heater so that the heat generation amount of the heater 9 becomes a normal value, and simultaneously turns on the exhaust fan 12, and then the time from this time. the group type the stage, and a time value (t ₄₎ in which the count for counting the set time value (t ₄₎ step, and a time value that is the count and compare (t ₄₎ the set time value that is less than (t ₄₎ is greater Or the same, the stirring motor 6 is driven, and when the counted time value t ₄ is smaller than the set time value T ₄ , the initial stage when the restraint of the stirring motor 6 is judged to be restraint other than freezing is performed. Returning to a state, determining whether the driven stirring motor is constrained when the stirring motor 6 is driven, and counting the number of times of stirring the motor from this time when the stirring motor 6 is still constrained. And the stirring motor (6) If it is not restrained, the process returns to the normal stirring operation immediately, and when the restraint number of the stirring motor 6 is counted, the restraint count value t ₅ of the counting agitator motor is counted. ₅ ) and when the restraint count value t ₅ of the counting stirring motor is greater than or equal to the set count value T ₅ , all subsequent processes are stopped and the stirring motor restraint state by freezing is displayed. If the restraint count value (t ₅ ) of the stirring motor to be counted is smaller than the set count value (T ₅ ), the step of returning to the initial state when the restraint of the agitator motor is judged to be restraint other than freezing is displayed.

When the motor restraint time value t ₆ is greater than or equal to the set time value T ₆ , all subsequent processes are stopped and the stirring motor restraint state other than freezing is displayed on the display unit, and the restraint time of the stirring motor counted. When the value t ₆ is smaller than the set time value T ₆ , the step of returning to the initial state when the restraint of the stirring motor 6 is judged to be restraint by freezing is sequentially performed.

Hereinafter, a process of performing the stirring operation according to the present invention will be described in detail.

As shown in FIG. 5, the stirring blade 8 is rotated by the driving of the stirring motor 6 while mixing the food waste introduced into the fermentation tank 5 with the fermentation aid. When the food waste and the fermentation aid in the fermentation tank 5 are frozen due to foreign substances or low temperature of the outside air, driving of the stirring motor 6 becomes slower than necessary or the driving stops completely. Since the controller recognizes the additional means, the stirring motor 6 detects the restrained state.

In this way, when the stirring motor 6 is detected in the restrained state, the driving of the stirring motor 6 is stopped, and when the stirring motor is detected in the non-constrained state, the stirring is continued, but the stirring motor ( When the agitation motor is stopped by the restraint of 6), if the outside air temperature is detected by a separate temperature sensor and the detected outside air temperature value (t) is sent to the controller, the controller is connected to the detected temperature value (t). If the detected temperature value t is less than or equal to the set temperature value T, the restraint of the stirring motor 6 is determined to be restraint by freezing, and the algorithm corresponding thereto is determined. When the detected temperature value t is greater than the set temperature value T, the restraint of the stirring motor 6 is determined to be a restraint (general restraint) other than freezing, and an algorithm corresponding thereto is performed.

First, when the restraint of the stirring motor 6 is determined to be restrained by freezing, a process of informing the user of this will be described below according to one embodiment and another embodiment.

6A, when the restraint of the stirring motor 6 is determined to be restrained by freezing, as shown in FIG. 6A, the heater is turned on and the exhaust fan at the same time so that the heating value of the heater 9 for heating the fermentation tank 5 becomes the maximum value. After 12) is turned off, an additional means (timer) counts the time from this time and sends the counted time value t ₁ to the controller, where the controller counts the time value t ₁ and the pre-input. the case set time value (t ₁₎ compare greater and less than the time value (t _1), the set time value (t ₁₎ is the count to or greater is provided with a stirring motor 6 is driven by the control of the controller, whereas When the time value t ₁ to be counted is smaller than the set time value T ₁ , the restraint of the stirring motor 6 is returned to the initial state when it is determined that the restraint by freezing.

As described above, it is determined that the restraint of the stirring motor 6 is a restraint by freezing, since the heater is turned on and the exhaust fan 12 is turned off so that the calorific value of the heater 9 for heating the fermentation tank 5 is at the maximum. Considering that it is possible to thaw frozen food waste and fermentation aids in the fermenter (5) and to prevent cold air from the outside that is a factor of freezing into the fermenter (5).

When the stirring motor 6 is driven, it is determined again that the driven stirring motor is constrained. If the stirring motor is still constrained, a separate means counts the number of stirring motors from this time and sends it to the controller. If the stirring motor 6 is not constrained, it returns to normal stirring operation immediately.

On the other hand, the restraint frequency value t ₂ of the stirring motor counted and sent to the controller is compared with the set frequency value T _{2 previously} input to the controller, in which case the restraint frequency value t ₂ of the stirring motor 6 is counted. ) Is greater than or equal to the set number of times (T ₂ ), all subsequent processes are stopped, and the stirring motor binding state by freezing is displayed on the display unit so that the user can know, and the stirring motor (6) counted on the contrary. When the confinement count value t _{2 of the} is smaller than the set number of times value T ₂ , the restraint of the stirring motor 6 returns to the initial state when it is determined that the restraint by freezing is constrained.

When the restraint of the stirring motor 6 is judged to be restraint by freezing and the state is displayed through the display unit of the device, the user visually checks this and appropriate measures accordingly (freezing of food waste and fermentation aid). It should be understood that

In another embodiment, as shown in FIG. 6B, when the restraint of the stirring motor 6 is determined to be restrained by freezing, the stirring motor is driven and the driven stirring motor 6 is restrained during the process until the user is notified of the restraining. Since a series of processes to determine again are the same as in one embodiment, reference may be made to one embodiment described above.

On the other hand, when it is determined again that the stirring motor 6 is restrained, if the stirring motor continues to be restrained, a separate means counts the stirring motor restraint time from this time and sends it to the controller, and the stirring motor 6 is restrained. If not, return to normal agitation immediately.

Constraining the time value of the stirring is the count sent to the controller motor (t ₃₎ is compared with the set time value (T ₃₎ input based on the controller, wherein the restraint time value of the stirring motor 6 is counted (t ₃₎ If the set time value is greater than or equal to T ₃ , all subsequent processes are stopped, and the stirring motor restraint state by freezing is displayed on the display unit so that the user can know and the count of the stirring motor 6 is reversed. When the restraint time value t ₃ is smaller than the set time value T ₃ , the restraint of the stirring motor 6 returns to the initial state when it is determined that restraint by freezing.

Next, when it is determined that the restraint of the stirring motor 6 is a restraint (general restraint) other than freezing, the process of informing the user of this is described below according to one embodiment and another embodiment.

As shown in FIG. 7A, when the restraint of the stirring motor 6 is determined to be restraint by freezing other than the freezing, the heater is turned on so that the calorific value of the heater 9 for heating the fermentation tank 5 becomes a normal value. After the exhaust fan 12 continues to be turned on, a separate means (timer) counts the time from this time and sends the counted time value t ₄ to the controller, at which time the controller counts. (t ₄₎ and the cycle time value that is the count by comparing the input set time value (T ₄₎ (t ₄₎ If equal to or greater than the set time value (T ₄₎ is stirred under the control of the controller motor ( When 6) is driven and the time value t ₄ , which is counted on the contrary, is smaller than the set time value T ₄ , the restraint of the stirring motor 6 is returned to the initial state when it is determined that the restraint by freezing is other than freezing.

In the above, the exhaust fan 12 is continuously turned on while the heater is turned on so that the heat generation amount of the heater 9 for heating the fermentation tank 5 becomes a normal value, and the restraint of the stirring motor 6 is restricted by freezing. In view of the fact that it is not necessary, the fermenter 5 does not need to be heated more than necessary, and food waste and fermentation microorganisms are not frozen even if cold air from the outside enters the fermenter.

When the stirring motor 6 is driven, it is determined again that the driven stirring motor is restrained. When the stirring motor 6 is still restrained, a separate means counts the number of times of stirring the motor from this time. The controller is sent to the controller, and when the stirring motor 6 is not constrained, it immediately returns to the normal stirring operation.

On the other hand is the count is compared with the bound count value of the stirring is sent to the controller motor (t ₅₎ is a group of the input set count value to the controller (T _5), wherein constraining the number of times the value of the stirring motor 6 is counted (t ₅ ) Is greater than or equal to the set number of times (T ₅ ), all subsequent processes are stopped, and the stirring motor restraint state by freezing is displayed on the display so that the user can know, and the stirring motor (6) counted on the contrary. When the number of times of restraint t ₅ is smaller than the set number of times T ₅ , the restraint of the stirring motor 6 is returned to the initial state when it is determined that restraint by restraint other than freezing.

In the above case, when the restraint of the stirring motor 6 is judged to be restraint other than freezing and the state is displayed through the display unit of the device, the user visually checks this and appropriate measures accordingly (removes foreign substances caught on the stirring blade). It should be understood that

In another embodiment, as shown in FIG. 7B, when the restraint of the stirring motor 6 is determined as being restrained by freezing, the stirring motor is driven and the stirring motor 6 is restrained during the process of notifying the user. Since a series of processes until determining again is identical to one embodiment, reference may be made to one embodiment described above.

On the other hand, when it is determined again that the stirring motor 6 is restrained, if the stirring motor continues to be restrained, a separate means counts the stirring motor restraint time from this time and sends it to the controller, and the stirring motor 6 is restrained. If not, return to normal agitation immediately.

The restraint time value t ₆ of the agitated motor counted and sent to the controller is compared with a preset time value T _{6 previously} input to the controller, where the restraint time value t ₆ of the agitated motor 6 counted. If this time is greater than or equal to the set time value (T ₆ ), all subsequent processes are stopped, and the stirring motor restraint state by freezing is displayed on the display so that the user can know, and the restraint time value of the stirring motor counted in the opposite direction. When (t ₆ ) is smaller than the set time value (T ₆ ), the restraint of the stirring motor 6 is returned to the initial state when it is determined that the restraint is caused by freezing.

Therefore, in the present invention, when the agitator motor is restrained, the cause of restraint is whether it is restraint by freezing or restraint other than freezing, and thus informs the user of the restraint, so that the user can quickly solve the restraint cause of the agitator motor. In addition, the defrosting step is performed when the constraining factor of the stirring motor is a constraining factor by freezing, so that the freezing restraint of the stirring motor may be released in this process.
