The shape and structure of the protrusion 111 and the vacuum sensing sensor 130 may be variously formed, and a detailed description thereof will be omitted.

A method of detecting the vacuum state of the vacuum packaging machine 100 using the protrusions 111 and the vacuum sensing sensor 130 will now be described. When the air is absorbed, the upper case 110 and the lower case 120 come into close contact with each other as the upper case 110 is broken.

The protrusion 111 provided in the upper case 110 is also moved toward the lower case 120 so that the sensing space S of the vacuum sensing sensor 130 provided in the lower case 120 is closed, The vacuum sensing sensor 130 transmits an electrical signal to the control unit 140 when the protrusion 111 is located in the sensing space S and the control unit 140 receives an electrical signal from the vacuum sensing sensor 130 When it is transmitted, it is judged that the vacuum is made.

Meanwhile, the controller 140 controls the heating unit 150 based on whether an electrical signal is transmitted from the vacuum sensing sensor 130.

Since the position where the heater 153 is formed differs depending on the structure of the vacuum packing machine, It is not specific to the invention.

Since the heater 153 generates heat, it can be overheated by continuously generating heat. Overheating generated by the heater 153 may adversely affect other structures of the vacuum packaging machine 100 And may damage the wrapping paper.

In order to prevent the heater 153 from being overheated, the vacuum packing machine 100 of the present invention includes a lower insulating plate 160 provided below the heater 153 and an upper insulating plate 170).

A plurality of holes 161 are formed in the lower insulating plate 160 and a thermal fuse 155 is disposed under the upper insulating plate 160. The heater 153 and the thermal fuse 155 are physically Isolation.
