FIG. 6 is a block diagram of an apparatus for treating food using microorganisms according to an embodiment of the present invention. FIG.

The apparatus for treating food using microorganisms according to a preferred embodiment of the present invention is connected to a drain port of a sink and decomposes food and food by stirring with microorganisms and discharges the food into a liquid state.

That is, the food processing apparatus 100 using the microorganisms has a box shape in which a space is formed therein, an upper portion is opened to form an inlet port 111, and a lower portion of the chamber is provided with a drain port 112 through which food is decomposed and discharged chamber 110, as shown in FIG.

A plurality of perforations 141 are formed in the chamber 110 and a perforated network 140 having a semicircular cross section is installed in the chamber 110. A rotating shaft 120 is provided on the perforated network 140, A stirring blade 130 is coupled to the rotating shaft 120 at right angles to the rotating shaft 120 and rotated together with the rotating shaft 120.

At this time, the rotation of the rotation shaft 120 is driven by a control unit installed on the main board connected to the power supply unit.

The food is dropped into the perforated network 140. When the rotating shaft 120 is rotated, the food is poured into the pouring opening 111, So that the food and the microorganism are stirred.

In this case, stirring means to make two or more materials having different physical or chemical properties into a uniform mixture state by using external mechanical energy.

After stirring for about 1 to 24 hours, the food is decomposed by the microorganisms into a liquid state, and is drained through the drain port (112).

A cover opening / closing detection sensor 160 is provided on a cover 191 provided at a loading port 111 into which food is inputted and when the cover 191 is opened, it senses the cover opening signal and transmits a signal to a controller installed on the main board, The stirring of the food and the microorganism is stopped.

That is, when the cover is opened to insert food into the chamber 110 or to repair the chamber 110, the user may be injured by the rotating stirring wing 130, and the food or microorganism in the stirring may be centrifuged As shown in FIG. In order to prevent this, when the cover 191 is opened, it senses it and stops stirring of food and microorganisms.

At this time, detection of opening of the cover 191 is performed through a cover opening / closing detection sensor 160, and the cover opening / closing detection sensor 160 uses a magnet sensor as a contact type sensor.

The magnet sensor is a detector used mainly for detecting an intruder by being installed at a place where a door or a window is opened or closed. When the magnet portion and the switch portion come close to each other or close to each other, the electric contact is opened or closed.

The magnet unit is coupled to one side of the cover 191, and the switch unit is installed at a charging port 111 corresponding to the magnet unit 191.

The cover opening / closing detection sensor 160 may use a non-contact type sensor in addition to the magnet sensor.

When the cover opening / closing detection sensor 160 senses the opening of the cover 191, a cover opening signal is transmitted to the controller. The controller receives the cover opening signal and rotates the stirring wing 130 The driving of the vehicle is stopped. Thus, while the cover 191 is opened, the stirring is automatically stopped to prevent the floating state of the cover 191, so that the food or microorganisms can be prevented from protruding from the outside.

When the cover 191 is closed, the cover opening / closing detection sensor 160 senses the closing of the cover 191 and transmits a signal to the controller installed on the main board. When the controller 191 receives the signal, the controller starts stirring.

That is, when the cover 191 is closed while the cover 191 is opened, the cover opening / closing detection sensor 160 provided on the cover 191 senses this and transmits a cover closing signal to the control unit. (Not shown) that rotates the stirring wing 130 by receiving the cover opening / closing signal.

If the cover 191 is closed again after the food is inserted or the A / S is finished after the cover 191 is opened for feeding food or A / S, and the stirring is stopped, The agitation can be resumed and the efficiency of the apparatus can be increased.

In addition, when the cover 191 is closed but the power supply is shut off and power is supplied from the outside and the control unit can be operated, the control unit starts driving the motor without any operation for further driving It is also possible to start stirring automatically.

The control unit installed on the main board controls the heating member 150 installed inside or outside the chamber 110 where the food is stirred with the microorganisms when the nighttime mode is selected by the predetermined time or the user selects the midnight mode selection signal And then the internal temperature of the chamber 110 is heated to a predetermined first temperature range.

That is, since the amount of food to be injected is almost zero during the night time, in order to concentrate on culturing the microorganisms rather than stirring the food and microorganisms, the control unit installed on the main board may be operated at a predetermined night- When a night-time mode switch provided outside of the chamber 110 is pressed, a midnight-mode selection signal is received to drive the heating member 150 provided inside or outside the chamber 110, And is heated to the set first temperature range.

The heating member 150 is attached to the outside of the chamber using a silicone heater, and may be connected to the main board to start or stop heating by a signal of the control unit. The silicon heater refers to a structure in which a highly heat-resistant tungsten resistor is disposed in a heater and is hardened by a ceramic, and is excellent in high heat resistance and high insulation.

Alternatively, the heating member 150 may be provided as a hot line to uniformly place heat lines in the chamber 110 or the perforated network 140, and may be connected to the main board to start or stop heating according to a signal of the controller .

The first temperature range is generally set at 30 to 40 DEG C at which microorganisms are cultured well.

Conditions for culturing the microorganisms are usually appropriate temperature and humidity, smooth air or oxygen flow, and the temperature is suitably from 30 to 40 DEG C and the humidity is about 70%. However, the conditions may vary depending on the type of microorganism.

In addition, since it is possible to be disturbed by the noise caused by the operation of the food processing apparatus using microorganisms in the middle of the night, it is possible to use the microorganism- When the mode switch is pressed, the controller receives the midnight mode selection signal, stops driving the rotation shaft 120, and stops stirring the food and microorganisms.

The controller monitors whether a temperature in the heated chamber is maintained in a predetermined first temperature range for a preset time by using a temperature sensor (not shown) provided inside or outside the chamber 110, And when the temperature is out of the first temperature range, heating is performed again.

That is, a temperature sensor (not shown) is provided inside or outside the chamber 110 to be connected to the main board, and the temperature of the chamber 110 is maintained at a predetermined first temperature range, that is, 40 [deg.] C for a predetermined time. When the temperature of the chamber 110 deviates from the first temperature range, the heating member 150 is again heated to reach the first temperature range.

At this time, in order to prevent the power consumed by frequent heating from increasing, the chamber 110 may be made of an insulating material so that the temperature of the chamber 110 is maintained at a constant temperature by preventing the temperature from being lowered.

When the temperature in the chamber is out of a predetermined second temperature range in a state in which the nighttime mode is not selected by the user using a temperature sensor provided inside or outside the chamber, To a predetermined second temperature range.

That is, in the winter season, a bad odor may be generated due to a low temperature due to a low temperature of the microbial activity. To prevent this, the temperature sensor (not shown) provided inside or outside the chamber 110 controls the temperature in the chamber 110 If the controller senses the temperature outside the second temperature range and transmits a signal to the controller, the controller heats the inside of the chamber 110 using the heating member 150.

The second temperature range may be 10-15 < 0 > C, at which microorganisms actively decompose food.

A rotating shaft 120 is provided in a chamber 110 in which food is introduced and stirred with microorganisms and at least one stirrer 130 stirring the food and microorganisms is rotated on the rotating shaft 120 together with the rotating shaft 120, And the other end of the guide member is fastened.
