Hereinafter, a method of controlling the vacuum packaging machine 100 will be described in detail.

7 and 8 are block diagrams in which various components of the vacuum packaging machine 100 are electrically connected to each other, and a flowchart for controlling the vacuum packaging machine 100 is shown.

The digital controller 800 is embedded in the upper case 200 or the lower case 300, and the state information of the first switch 810, the second switch 811, the temperature switch 820, the pressure switch 821 is Input, the output signal is transmitted to the vacuum pump 500, the heater 600, the tri-color LED lamp 310, and consists of a microcomputer or IC chip having a calculation unit, memory of the program and data, timer and input and output, The vacuum packaging machine is safely controlled at low power by signals indicating various status information. In detail, the sealing materials of the first switch 810 and the second switch 811 are worn down by the opening and closing of the upper case 200 and the lower case 300, even when the juice and the liquid overflow during vacuum packaging. Safety problems such as short circuits are solved.

As the power source 830, a household AC power source rectified by a battery or a transformer 831 and a rectifier circuit (not shown) is used. A temperature fuse 832 for the transformer and a temperature fuse 833 for the heater are respectively installed in the transformer 831 and the heater 600 and connected to the power source 830, so that the power source 830 is cut off when overheated.

The first switch 810 is installed to protrude on the contact surface 203 of the upper case or the contact surface 302 of the lower case, as shown in Figure 4, the second switch 811 of the upper case as shown in FIG. It protrudes from the contact surface 203 or the contact surface 302 of the lower case. That is, the first switch 810 and the second switch 811 can be installed anywhere on the contact surface. However, as shown in FIG. 4, the hard pads 331 face each other at the contact surface 302 of the lower case. The mechanical structures of the first switch 810 and the second switch 811 may vary, and the first switch 810 and the second switch 811 are turned on by protrusions formed in the upper case 200. Can be off.
When the first switch 810 and the second switch 811 are automatically operated together as the upper case 200 is closed, the digital control unit 800 connected to the first and second switches may include the first and second switches. Receiving a signal to operate the two switches are set in the vacuum packaging mode to operate the vacuum pump 500 and the heater 600.

The temperature switch 820 is installed in the transformer 831, when the temperature is above a predetermined temperature (or off) is a switch consisting of a bimetal, thermistor, etc., the signal of the temperature switch 820 to the digital control unit 800 The transfer of the vacuum pump 500 and the heater 600 is stopped, and the digital controller 800 moves to an initial preparation state 840 (FIG. 8A), thereby improving the safety of the vacuum packaging machine 100.

The pressure switch 821 is installed in a hose (not shown) connecting the vacuum pump 500 and the suction port 420 to each other. When the pressure is higher than a predetermined degree of vacuum, the pressure switch 821 is configured as a strain gauge, a piezoelectric element, or the like. The signal of the pressure switch 821 is transmitted to the digital control unit 800 so that the operation of the vacuum pump 500 is stopped or the completion of vacuum is determined by the digital control unit 800.

The vacuum pump 500 is built in the lower case 300, for example, the DC motor is driven by the digital control unit 800 is operated by this DC motor.

The heater 600 is installed on the surface of the upper case 200 or the lower case 300 and is operated by the digital control unit 800.

 The three-color LED lamp 310 is an LED lamp in which the green LED and the red LED are formed of one lamp, and three colors are expressed in green, red, and orange according to the combination of the green LED and the red LED, and the lower case. It is installed on the upper rear part of the 300 and is electrically connected to the digital control unit 800, and is displayed in different colors in green, orange, and red, respectively, in the ready state, the vacuum pump operation, the heater operation.

The digital controller 800 largely controls the vacuum packaging machine 100 by dividing it into a vacuum packaging mode for vacuum packaging and a container mode for vacuum packaging. A detailed description will be given with reference to the flowchart in FIG.

As shown in FIG. 8A, when the initial power is turned on, the digital control unit 800 stops the vacuum pump 500 and the heater 600, and the tricolor LED lamp 310 emits green light. It becomes

When the first switch 810 and the second switch 811 are operated together, for example, within a predetermined time, the vacuum packaging mode is set by the digital controller 800 to the vacuum packaging mode in the ready state 840. In step 850, when the second switch 811 is operated for a predetermined time, the digital controller 800 sets the container mode in the ready mode 840 to the container mode setting step 860. Is fulfilled.

First, a case where the vacuum packaging mode setting step 850 is performed will be described.

Proceeding to the vacuum pump step 851, the vacuum pump 500 is operated by the digital control unit 800, whereby a vacuum is formed in the vacuum chamber 400. Vacuum packaging paper is vacuumed through the vacuum chamber 400. At this time, the three-color LED lamp 310 is displayed in orange.

In the vacuum determination step 852, it is determined by the digital control unit 800 whether the predetermined vacuum degree is obtained through the signal of the pressure switch 821, and if the predetermined vacuum degree is not reached, the vacuum pump step 851 continues. When the predetermined degree of vacuum is reached, execution proceeds to the next heater stage 854.

The heater step 854 is powered by the heater 600 for a predetermined time, for example, 4 seconds by the digital control unit 800 is heat-sealed vacuum packaging paper. At this time, the three-color LED lamp 310 is displayed in red.

In some cases, when it is determined that the vacuum completion step 852 of the vacuum packaging paper mode is completed, a vacuum pump and a heater step 853 in which the vacuum pump 500 and the heater 600 are operated together are added. Thereafter, the process proceeds to the heater stage 854. Specifically, the vacuum pump 500 is also operated together for an initial predetermined time, for example, 4 seconds, during which the vacuum wrapping paper is heat sealed, so that the vacuum degree of the vacuum wrapping paper becomes more accurate and improved.

After the heater step 854, the process returns to the return step 855, and the digital controller 800 returns to the ready state 840.

In FIG. 8B, the first switch 810, the second switch 811, and the temperature switch 820 are interrupted in the vacuum packaging paper mode, and the vacuum pump 500 and the heater 600 are stopped. A control method transitioned to 840 is shown.

In the temperature interrupt 870, in the vacuum pump step 851, the heater step 854, and the vacuum pump and heater step 853, the transformer 831 becomes a predetermined temperature or more, and the temperature switch 820 is operated and the temperature switch The signal of 820 is transmitted to the digital control unit 800 to be transferred to the initial preparation state 840 in which the vacuum pump 500 and the heater 600 are stopped. This prevents overheating of the vacuum packaging machine 100. In addition, the temperature interrupt 870 is frequently checked in the vacuum pump step 851, the heater step 854 and the vacuum pump and heater step 853, and the vacuum packaging interrupt 880 when the temperature switch 820 is not operated. Is implemented.

The vacuum packaging interrupt 880 is the digital control unit when the first switch 810 or the second switch 811 is turned off for a predetermined time (for example, 0.5 seconds) due to the upper case 200 being opened. By the 800, the vacuum pump 500 and the heater 600 are shifted to the initial ready state 840. Otherwise, the general vacuum pump step 851, the heater step 854, and the vacuum pump and heater step 853 are performed.

Next, the case where the container mode setting step 860 (FIG. 8A) is shifted will be described.

Proceeding to the vacuum pump step 861, the vacuum pump 500 is operated by the digital control unit 800, thereby forming a vacuum in the container 901. At this time, as shown in FIG. 5, the inlet 420 and the container 901 are connected to each other by the hose assembly 700 by the user in advance. In addition, the tri-color LED lamp 310 is displayed in orange.

The vacuum determination step 862 is determined by the digital control unit 800 whether the predetermined vacuum degree through the signal of the pressure switch 821, if the predetermined vacuum degree is not reached, the vacuum pump step 861 continues When the predetermined degree of vacuum is reached, execution proceeds to the next return step 863.

In the returning step 863, the digital controller 800 returns to the ready state 840.

In FIG. 8C, the control method is interrupted by the second switch 811 and the temperature switch 820 in such a container mode, and the control method is transferred to the initial preparation state 840 in which the vacuum pump 500 and the heater 600 are stopped. Is shown.

In the temperature interrupt 870, the transformer 831 is above a predetermined temperature in the vacuum pump step 861 so that the temperature switch 820 is operated and the signal of the temperature switch 820 is transmitted to the digital controller 800. The vacuum pump 500 and the heater 600 are shifted to the initial ready state 840. This prevents overheating of the vacuum packaging machine 100. Then, the temperature interrupt 870 is frequently checked in the vacuum pump step 861, and if the temperature switch 820 is not operated, the temperature interrupt 870 is transferred to the container interrupt 890.
