Apparatus for vacuum packages and method of controlling it

Abstract

Disclosed is an apparatus for vacuum sealing a plastic bag and/or container and a method of controlling the apparatus. The method of controlling the apparatus having an upper casing with an upper concave part therein, a lower casing with a lower concave part therein, a vacuum chamber formed by the close contact between the upper concave part and the lower concave part, such that an opening portion at one end of the plastic bag is inserted into the vacuum chamber, a vacuum pump for providing vacuum to the vacuum chamber, and a heater for heat sealing the plastic bag being in a vacuum sate at the front portion thereof, including the steps of: descending the upper casing above the lower casing to thereby operate a first switch and a second switch together, the first switch and the second switch disposed protrudedly on the contact surface between the upper casing and the lower casing, being connected to a digital control unit; and operating the vacuum pump and the heater in a sequential order by the control of the digital control unit, such that the plastic bag is vacuumed in a plastic mode.

Description

TECHNICAL FIELD [0001] The present invention relates to an apparatus for vacuum sealing a plastic bag and / or a container in which articles like food for storage are put in a vacuum state to thereby prevent the oxidization or decay of the articles and a method of controlling the apparatus, and more particularly, to an apparatus for vacuum sealing a plastic bag and / or a container wherein one of a plastic bag mode and a container mode is selected by just touching switches under the control of a digital control part, such that if the container mode is selected, only the container is vacuumed by connecting a hose to a suction inlet in a vacuum chamber, while the vacuum chamber is not being vacuumed, thereby preventing the air leakage in conventional vacuum sealing apparatuses. BACKGROUND ART [0002] Generally, articles like food for storage are packaged by plastic wrap or a vinyl bag and then placed in refrigerators. In this case, however, the articles stay good for a predetermined length...

Benefits of technology

[0005] Accordingly, the present invention has been made to solve the above-described problems, and it is an object of the present invention to provide an apparatus for vacuum sealing a plastic bag and/or a container and a method of controlling the apparatus, wherein a plastic bag mode is set by pressing a first switch and a second switch to

Problems solved by technology

In this case, however, the articles stay good for a predetermined length of time, but as time is elapsed, they get oxidized and decayed by the air charged in the interior of the packaged container or vinyl bag.

At that time, there occurs a problem that ventilating means 67 (see FIG. 1c) that is opened normally should be continuous to be pressed by means of a button 66 (see FIGS. 1b and 1c) through the user during vacuum sealing, thereby making it inconvenient to use.

This even may make the user get shocked.

However, th
