More particularly, the vacuum packaging operation is surely performed and the vacuum is secured while the size of the chamber portion can be reduced by providing a chamber portion whose rear portion is blocked by the folding portion. The present invention relates to a vacuum packaging machine capable of minimizing waste of wrapping paper.

A vacuum packaging machine is a packaging device used to store food for a long time by preventing the oxidation of food by putting a vacuum treatment object such as food to be stored in a wrapping paper and then releasing air and sealing it. That is, food may be prevented from being damaged by keeping food at a low temperature using a refrigerator, but it may be possible to store food for a longer period of time by storing the food in a vacuum package so that the food does not come into contact with air.

1 is a perspective view of a general vacuum packaging machine.

As shown in FIG. 1, a general vacuum packaging machine is hinged to a main body 10 having various parts such as a vacuum pump (not shown) installed therein and the main body 10 to open and close an upper surface of the main body 10. It consists of a cover portion 20 that can be.

The main body portion 10 includes a lower sealing member 12 installed around the lower chamber portion 11 to form the lower chamber portion 11 in the left and right directions, and an air inlet formed in the lower chamber portion 11. 13, a vacuum pump (not shown) connected to the air inlet 13 and suctioning air, and heating means 14 installed in the left and right directions in front of the lower chamber part 11 to heat seal the vacuum wrapping paper. ).

In addition, the cover part 20 is mounted at a position corresponding to the lower sealing member 12 and seals the lower chamber part 11 when the cover part 20 closes the upper surface of the main body part 10. And an upper sealing member 22 forming a vacuum space, and a pressing member 23 installed at a position corresponding to the heating means 14 and pressing the heating means 14 when descending. In this case, an upper chamber portion 21 recessed in the left and right directions may be formed on the bottom surface of the cover portion 20 in which the upper sealing member 22 is installed, to correspond to the lower chamber portion 11.

The operation of the general vacuum packaging machine configured as described above is as follows.

First, the user puts the object 40 to be vacuumed inside the vacuum wrapping paper 30, places the opening 31 of the vacuum wrapping paper 30 in the lower chamber portion 11 of the main body portion 10 and the cover portion The space between the lower chamber part 11 and / or the upper chamber part 21 is sealed by rotating the 20 to bring the lower sealing member 12 and the upper sealing member 22 into close contact.

In such a state, when the predetermined operation switch 15 is pressed, a vacuum pump (not shown) is operated, and air in the sealed space such as the lower chamber part 11 is moved to the air inlet 13 according to the operation of the vacuum pump. Will be inhaled. Accordingly, the lower chamber part 11 becomes a vacuum space and sucks air in the vacuum wrapper 30 through the opening 31 of the vacuum wrapper 30 positioned in the lower chamber part 11.

When the vacuum treatment inside the vacuum wrapping paper 30 is completed in the same manner as described above, the power is applied to the heating means 14 while the pressing member 23 presses the heating means 14, so that the vacuum wrapping paper 30 The opening 31 of the heat sink is heat-sealed to achieve sealing.

However, the conventional vacuum packaging machine has a sealed space between the upper sealing member 22 and the lower sealing member 12, that is, between the lower chamber portion 11 and the upper chamber portion 21 as the cover portion 20 is closed. Since it is formed, the vacuum wrapping paper 30 should be positioned exactly in the lower chamber part 11.

If the vacuum wrapping paper 30 is not located in the lower chamber part 11 formed by the lower sealing member 12 and a part of the vacuum wrapping paper 30 is in a position outside the lower chamber part 11, the vacuum There is a problem that the vacuum treatment of the wrapping paper 30 is not made.

In order to solve this problem, the conventional vacuum packaging machine forms the lower chamber portion 11 and / or the upper chamber portion 21 to have a predetermined width in the front-rear direction. That is, the width of the chamber portions 11 and 21 is wide so that the user does not have much difficulty in placing the vacuum wrapping paper between the chamber portions 11 and 21.

First, the wider the width of the chamber portions 11 and 21, the farther the distance between the heat-sealed portion between the opening 31 of the vacuum wrapping paper 30 and the heating means 14 is increased. If the sealed part is cut out for reuse, the amount of waste is increased. That is, in order to reuse the vacuum wrapping paper 30, the sealing portion of the heat-sealed seal line should be formed to form the opening 31. However, as described above, when the width of the chamber portions 11 and 21 is widened, the vacuum wrapping paper 30 may be formed. Since the side of the opening 31 needs to be cut a lot, the waste of the vacuum wrapping paper 30 becomes severe.

Second, as the width of the chamber parts 11 and 21 increases, the space for installing the chamber parts 11 and 21 is unnecessarily large, so that the vacuum packaging machine protrudes forward. In detail, in the general vacuum packaging machine, components for vacuum packaging are hardly mounted in the lower space of the main body portion 10 in which the chamber portions 11 and 21 and the heating means 14 are installed. However, in the conventional case, as the width of the chambers 11 and 21 increases, the unnecessary space is increased. Thus, the vacuum packaging machine has a wide width in the front and rear direction, so that a large area is required for installing the vacuum packaging machine. Done.

On the other hand, the general vacuum packaging machine is a part required for the vacuum treatment of the chamber (11, 21), such as a vacuum pump (not shown) is located in the majority of the main body portion 10, the lower chamber 11 is the main body It is formed to be recessed downward from the upper surface of the portion 10.

Therefore, the conventional vacuum packaging machine has no choice but to form an air inlet 13 on the lower surface of the lower chamber part 11, and thus, when vacuuming wet foods or the like, the moisture from the vacuum wrapping paper 30 is lowered. The risk of flowing out into the chamber part 11 and flowing into the air inlet 13 becomes very large.

In this case, various products such as a vacuum pump (not shown) may be damaged, and many problems may occur such as a risk of a safety accident such as an electric shock.
