The present invention relates to an automatic vacuum packaging machine, the present invention is to solve the inconvenience of pressing the hood artificially, unlike before, to automatically do this, it is possible to adjust the degree of vacuum and the vacuum time according to the type of food inside the vacuum packaging bag The present invention relates to a vacuum packaging machine having a filter means for separating vacuum particles and heavy liquids discharged during vacuum operation.

Conventional vacuum packaging machines have been described in US Patent No. 3,731,054, "Heat sealer," which has a configuration in which the hood is hinged to the container, and the heat sealing device is equipped with a predetermined switch means in the container. When the hood is seated on the container, the hood is brought into contact with the switch means, and the electric circuit is completed. Since the power supply is stopped, there is a disadvantage in that the hood must be pressed during the sealing operation.

A vacuum packaging machine that overcomes these problems has been disclosed in Korean Patent No. 0415070, and the vacuum packaging machine has a structure in which a hook portion is formed in the hood portion so as to form a constant coupling groove in the container and be coupled to the coupling groove. Since the door locks must be mounted on both side ends of the vacuum packaging machine, the door locks are often touched incorrectly during the vacuum operation, and after the vacuum operation is completed, the door locks must be manually removed from the hook container. There is a problem that the separation operation is inconvenient, when the hook portion and the coupling groove when the hood is coupled to the container, the hook portion or the coupling groove is broken due to the impact of the coupling, and the appearance of the hook portion mounted on the hood is not beautiful. .

In addition, the conventional vacuum packaging machine does not have a means for removing oil and foreign matter in the vacuum packaging bag has a problem in that the oil and foreign matter is introduced into the vacuum pump to reduce the pumping power of the vacuum pump and at the same time malfunction.

In the case of the patent, the vacuum packaging bag is delayed because the inside of the vacuum packaging bag is vacuumed after the vacuum pump vacuums the air in the concave means in the case of putting food or food containing no foreign matter in the vacuum packaging bag. Problem, if there is a large amount of foreign matter in the food, foreign matter overflows the lower recess means and foreign matter flows into the vacuum packaging machine. There has been a feeling.

In addition, even in the case of this patent, there is an inconvenience in that the hood must be kept pressed in order to firmly contact the hood during the vacuum operation.

Further, in this patent, the vacuum releasing device for releasing the vacuum is composed of ventilation means for vertically venting the recess means and means for selectively closing the vent means to isolate the recess from the surroundings. In order to vertically penetrate the auxiliary means, the ventilation means must be formed on the upper surface of the hood. If the vacuum release device is touched incorrectly during the vacuum operation, the vacuum state of the recess is released and the food inside the vacuum bag is leaked to the outside. There has been a problem that can be.
