Accordingly, when the body 71 is fixed to strongly adhere to the bottom surface of the housing 13, the second sealing member 95, the first sealing members 87 and 89, and the ball member by the pressing member 97. 75 adheres more firmly. This improves the sealing effect.

Referring to FIG. 9, the food waste disposal system according to the embodiment of the present invention includes a first actuator (hereinafter referred to as a "drying / cutting motor") 201 for driving the impeller 33.

The drying / cutting motor 201 rotates the impeller 33 so that the food in the food processing space 11 is cut and stirred. As the food is agitated by the impeller 33, the food may be dried more effectively by the heat transferred from the heater 29.

The drying / cutting motor 201 is connected to a rotating shaft 51 connected to the impeller 33 to rotate the rotating shaft 51. The drying / cutting motor 201 can rotate the impeller 33 in both directions, ie a first rotational direction preceded by the convex side of the blade 55 and a second rotational direction preceded by the concave side of the blade 55. It works. Here, the first rotational direction corresponds to the clockwise direction of FIG. 6 and the second rotational direction corresponds to the counterclockwise direction of FIG. 6.

When the impeller 33 rotates in the first rotation direction, the food mainly moves toward the radially outer side of the housing 13, and when the impeller 33 rotates in the second rotation direction, the food is radially inside the housing 13. It is mainly moved to.

On the other hand, the food waste processor according to the embodiment of the present invention includes a second actuator (hereinafter referred to as "discharge motor") 203 for driving the food discharge control unit 70.

The discharge motor 203 drives the food discharge control unit 70 to selectively open and close the food outlet 17 of the housing 103.

The discharge motor 203 is connected to the rotary shaft 77 so as to rotate the rotary shaft 77 of the food discharge control unit 70.

And the food waste processor according to an embodiment of the present invention includes a control unit 205 for controlling the operation of the drying / cutting motor 201 and the discharge motor 203. The control unit 205 also controls the operation of the heater 29. At this time, the control unit 205 controls the heater 29 on-off. That is, the control unit 205 controls the heater 29 so that the heater 29 repeats the on and off states when the food waste processor starts to operate. At this time, the duration of the on state and the off state is determined according to various control conditions, and the heater 29 is controlled accordingly. And the control unit 205 serves to control the overall operation of the food waste processor.

Control unit 205 may include a microprocessor, memory, and other related hardware. The microprocessor may be configured to operate by a program programmed to perform each step of the food waste processor control method according to the embodiment of the present invention described below, and the memory stores various information for performing the control method.

On the other hand, the exhaust gas temperature sensor 207 for detecting the temperature of the exhaust gas discharged from the food processing space 11 and outputs a corresponding signal.

For example, the exhaust gas temperature sensor 207 is installed in the gas outlet 14 for discharging the gas generated in the food processing space 11 during the cutting and drying of the food to detect the temperature of the exhaust gas. It may be installed in the outlet 14.

On the other hand, a heater temperature sensor 209 for detecting the temperature of the heater 29 and outputting a corresponding signal is provided.

For example, the heater temperature sensor 209 may be installed to contact the heater 29 to detect a temperature of the heater 29 and output a signal indicating the detected temperature.

As shown in FIG. 9, the control unit 205 uses an exhaust gas temperature sensor to receive signals indicating exhaust gas temperature and heater temperature from the exhaust gas temperature sensor 207 and the heater temperature sensor 209, respectively. 207 and heater temperature sensor 209 are each electrically connected.

The control unit 205 controls the heater 29 on-off based on the signal of the exhaust gas temperature sensor 207 and the signal of the heater temperature sensor 209, and the heater 29 is turned on. The operation of the drying / cutting motor 201 and the discharge motor 203 is controlled according to the ratio of the time controlled in the state.

In addition, an exhaust fan 211 may be provided for flowing the gas so that the exhaust gas may be discharged through the gas outlet 14, and the control unit 205 outputs a control signal to operate the exhaust fan 211. To control.

For example, the exhaust fan 211 may be installed in the gas outlet 14 and operate to have one or more stages set in advance.

Hereinafter, referring to FIG. 10, a control method of a food waste processor according to an embodiment of the present invention will be described.

First, when the main power of the food waste processor is turned on or the operation is completed by processing the food waste, the control unit 205 controls the food waste processor in the standby mode.

In the standby mode, the heater 29, the drying / cutting motor 211, and the discharge motor 203 are all controlled in an off state, and the exhaust fan 211 is controlled to operate in the lowest stage.

This standby mode is maintained until the operation button for food waste disposal is on.

When the operation button is turned on for the processing of the input food waste, the control unit 205 performs the first to fifth control modes and the discharge mode sequentially to cut the food waste and dry the food waste storage box. Move to 109.

The control unit 205 periodically detects the temperature of the exhaust gas discharged from the food processing space 11 and the temperature of the heater 29 at predetermined time intervals to select an appropriate control mode. The exhaust gas temperature and the heater temperature are detected by the exhaust gas temperature sensor 207 and the heater temperature sensor 209, respectively, and then the corresponding information is transmitted to the control unit 205.

First, the control unit 205 controls the on-off operation of the heater 29 based on the exhaust gas temperature and the heater temperature.

In this case, referring to FIG. 10, while the first to fifth control modes are performed, the control unit 205 maintains the heater 29 such that the heater temperature is maintained at about 120 ° C. and the exhaust gas temperature is maintained at 70 ° C. or lower. Control on and off. For example, when the heater temperature is lower than 120 ° C., the heater temperature is 120 ° C. in a manner that increases the on operating time of the heater 29, and when it is higher than 120 ° C., increases the off operating time of the heater 29. Can be kept close to. On the other hand, for example, when the temperature of the exhaust gas is higher than 70 ° C, the temperature of the exhaust gas may be maintained at 70 ° C or lower by turning off the operation of the heater 29. That is, the control unit 205 properly controls the duration of the on state and the duration of the off state while controlling the heater 29 on and off, whereby the heater temperature is maintained near 120 ° C. and the exhaust gas temperature is 70 ° C. or less. Control to maintain.

When the control unit 205 performs the on-off control of the heater 29 in this manner, as the food is dried, the on state duration during the operation of the heater 29 gradually decreases and the off state continues. Time gradually increases. That is, as the food is dried, the ratio of the on time to the total operating time of the heater 29 (that is, the sum of the on time and the off time) gradually decreases. Based on this, according to the food waste processor control method according to an embodiment of the present invention, the food waste while the control unit 205 changes the control mode in accordance with the ratio of the time that the heater 29 is controlled to the on (on) state Proceed with cutting and drying.

The control unit 205 controls the heater 29 on / off based on the comparison of the ratio of the time for which the heater 29 is controlled to the on state and a plurality of set ratios which are sequentially reduced. Control the direction of rotation and operating time.

More specifically, the control unit 205 controls the heater 29 on-off while the ratio of the time that the heater 29 is controlled to the on (on), the first setting ratio, the second setting ratio, the third setting ratio In addition, each control mode may be performed by setting a rotation direction and an operating time of the impeller 33 based on the comparison of the fourth set ratio.

Referring to FIG. 10, the execution condition of each control mode is that the first control mode is performed when the ratio of the time controlled in the on state of the heater 29 detected in real time is greater than or equal to a preset first set ratio (40%). If it is between the first set ratio and the second set ratio (34%), the second control mode is performed. If it is between the second set ratio and the third set ratio (30%), the third control mode is performed and the third set ratio and the third set ratio are performed. The fourth control mode is performed when it is between four set ratios (26%), and when it is smaller than the fourth set ratio, a fifth control mode is performed. Here, the ratio of the time that the heater 29 is controlled to the on state, and each set ratio is the average value of the duration of the on state for a predetermined time (for example, 10 minutes) is the total operating time (on time And the sum of the off times).

Referring to FIG. 10, while the first to fifth control modes are performed, the heater 29 is controlled on and off, the discharge motor 203 is kept off, and the exhaust fan 211 is exhausted. It is maintained to operate in the highest stage with the highest gas emissions. Cutting and drying of the food is optimally performed by adjusting the rotation direction, the on time, and the off time of the drying / cutting motor 201 for each of the first to fifth control modes. In Fig. 10, " 1 " and " 2 " written in brackets for each control mode of the drying / cutting motor row are respectively concave with the first rotational direction in which the convex side of the blade 55 of the impeller 33 rotates in the preceding direction. It means a second rotation direction in which the side surface rotates in the preceding direction.

First, the first control mode is performed when the ratio of the time for which the heater 29 is controlled to the on state is equal to or greater than a predetermined first predetermined ratio (40%).

In the first control mode, the drying / cutting motor 201 is controlled to repeat the state in which the impeller 33 rotates in the first rotation direction and the stop state. That is, in order to effectively remove moisture present in the food processing space 11 and water on the food surface at the beginning of the food processing process, the food is inverted intermittently to remove the water on the surface. For example, two steps of allowing the impeller 33 to rotate for 15 seconds in the first rotation direction and then stopping for 30 seconds are repeatedly performed. When the impeller 33 rotates in the first rotation direction, the food is moved by the blades 55 toward the side wall of the housing 13 so that the food can be effectively turned over.

In the second control mode, the third control mode, and the fourth control mode, when the ratio of the time when the heater 29 is controlled to be on is between the first set ratio (40%) and the second set ratio (34%). , Between the second set ratio (34%) and the third set ratio (30%), and between the third set ratio (30%) and the fourth set ratio (26%), respectively.

Referring to the table of FIG. 10, in the second control mode, the third control mode, and the fourth control mode, the impeller 33 rotates in the first rotation direction, a stationary state, and rotates in the second rotation direction. And control repeatedly to perform the four states of the stopped state. By allowing the impeller 33 to rotate alternately in the first rotation direction and the second rotation direction, the movement and stirring of the food in the food processing space 11 is further promoted and thus cutting and drying of the food can be performed more effectively. Can be.

In this case, as the second control mode, the third control mode, and the fourth control mode progress, the state in which the impeller 33 rotates in the first rotation direction continues and the state in which the rotation in the second rotation direction continues. The time can be controlled so that each gradually increases.

For example, in the second control mode, the impeller 33 rotates in the first direction of rotation for 10 seconds, stops for 30 seconds, rotates in the second direction of rotation for 25 seconds, and stops for 30 seconds. Can be controlled to repeatedly perform the step of doing so. In the third control mode, the impeller 33 rotates for 15 seconds in the first rotation direction, stops for 20 seconds, rotates in the second rotation direction for 35 seconds, and stops for 30 seconds. Can be controlled to perform repeatedly. In the fourth control mode, the impeller 33 rotates in the first rotation direction for 20 seconds, stops for 30 seconds, rotates in the second rotation direction for 45 seconds, and stops for 30 seconds. Can be controlled to perform repeatedly.

That is, as the second control mode, the third control mode, and the fourth control mode progress, the time for which the state in which the impeller 33 rotates in the first rotational direction is gradually increased to 10 seconds, 15 seconds, and 20 seconds. The duration of rotation in the second direction of rotation also increases gradually to 25 seconds, 35 seconds, and 45 seconds. Accordingly, the food is properly heated and the drying and cutting of the food can be performed more effectively by increasing the time for the stirring and cutting to be performed while the drying is to some extent. In particular, as the time for the impeller 33 to rotate in the first direction of rotation increases, the food moves more toward the side wall of the housing 13, so that the food comes into contact with the inner wall of the housing 13, thereby further promoting drying. Can be.

On the other hand, when the execution condition of the fourth control mode is finished, that is, when the ratio of the time for which the heater 28 is controlled to the on state is smaller than the fourth set ratio, the fifth control mode is performed.

Referring to FIG. 10, the fifth control mode is performed in two steps. That is, the impeller 33 is controlled to repeatedly perform four states of rotating in the first rotation direction, stopped state, rotating in the second rotation direction, and stopped state. The heater 29 is controlled on and off for one set time (e.g., 10 minutes), and then the heater 29 is controlled off for a second set time (e.g., 10 minutes). That is, in the fifth control mode, additional drying is performed during the first first set time and cooling of the processed food is performed while the heater 29 is turned off for the second second set time.

On the other hand, the control unit 205 sets the exhaust gas temperature at the reference time point at which the rate of change of the exhaust gas temperature reaches a preset value during the progress of the third control mode to the reference exhaust gas temperature, and the fourth control. When the difference between the temperature of the exhaust gas detected in real time during the mode progress and the reference exhaust gas temperature reaches a preset value, the condition of the ratio of the time of the on state of the heater 29 for executing the fifth control mode is satisfied. If not, the fourth control mode may be immediately terminated and the fifth control mode may be controlled to be performed. The preset value corresponding to the rate of change of the temperature of the exhaust gas may be a value corresponding to a temperature change of 0.1 ° C. for 10 minutes. The preset value corresponding to the difference between the temperature of the exhaust gas and the temperature of the reference exhaust gas may be 5 ° C. That is, the point of time when the phase change starts when the rate of change of the temperature of the exhaust gas reaches a preset value (0.1 ° C./10 minutes) during the third control mode is started. When the difference between the reference exhaust gas temperature and the actual exhaust gas temperature at the time point reaches 5 ° C., the food control is regarded as completed and the fourth control mode is immediately terminated and the fifth control mode is performed. As a result, the drying process may be prevented from continuing unnecessarily, and thus the food treating process may be shortened and energy efficiency may be increased.

On the other hand, the control unit 205 controls the heater so that the temperature of the exhaust gas approximates the preset maximum temperature, and the temperature of the exhaust gas at the time when the fourth control mode ends is 80 of the preset maximum temperature. If less than%, the additional drying mode in the same manner as the fourth control mode may be further performed before the fifth control mode. The preset maximum temperature may be 70 ° C. Therefore, when the temperature of the exhaust gas at the time point when the fourth control mode ends is about 80% of the preset maximum temperature, that is, about 64 ° C. or less, the control unit 205 performs the fourth control mode before performing the fifth control mode. The additional drying mode controlled in the same way as can be controlled to be carried out further. This means that if the temperature of the exhaust gas is low, it is considered that the food has not been dried yet to be further dried. For example, when the temperature of the exhaust gas at the end of the fourth control mode is between 64 ° C. and 61 ° C., additional drying may be performed for a time corresponding to about 20% of the total time required for the drying process already performed. When the temperature of the exhaust gas at the time point when the fourth control mode ends is less than 61 ° C., further drying may be performed during a preset maximum operating time or until the temperature of the exhaust gas reaches 61 ° C. This may prevent food from being discharged in a less dry state.

Meanwhile, the control unit 205 may control the first to fifth control modes to be performed within the range of the maximum operating time preset for each. For example, the preset maximum driving time may be set to 30 minutes for the first control mode, 40 minutes for the second control mode, 100 minutes for the third control mode, and 120 minutes for the fourth control mode. That is, even if the ratio of the time of the on state of the heater 29 for performing the first to fifth control modes does not satisfy the execution condition, within the range of the maximum operating time preset for each control mode. After each control step is performed to proceed to the next control step. Accordingly, even if the conditions for executing each control mode are not satisfied due to a mechanical malfunction or the like, it is possible to prevent the food waste processor from operating indefinitely.

After the fifth control mode is performed, the control unit 205 may control the discharge mode to be performed by operating the discharge motor 203 to open the food outlet 17 of the housing 13.

In the discharge mode, the operation of the heater 29 may be turned off and controlled to operate at the lowest stage of the exhaust fan 211. At this time, the drying / cutting motor 201 rotates the impeller 33 in the first rotation direction for 60 seconds, stops for 5 seconds, rotates in the second rotation direction for 30 seconds, and for 5 seconds. It may be controlled to repeatedly perform the stopping step.

Such a discharge mode may be performed for a predetermined time or may be installed to detect whether the food discharge is complete, and may be performed until the discharge of the sound plant is completed by the signal of the sensor.
