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...

Embodiment Construction

[0027] Now, an explanation of the preferred embodiments of the present invention will be in detail given with reference to attached drawings. FIGS. 3a to 8b show the preferred embodiments of a vacuum sealing apparatus 100 and a method according to the present invention. First of all, an explanation of the vacuum sealing apparatus 100 will be in detail given.

[0028] As shown in FIGS. 3a and 4, the vacuum sealing apparatus 100 includes an upper casing 200, a lower casing 300, a vacuum chamber 400, a vacuum pump 500, a heater 600, a hose assembly 700 and a digital control unit 800. Thereby, a plastic bag or a container 901 is vacuumed by means of the vacuum sealing apparatus 100. In some cases, the vacuum sealing apparatus can be manufactured only for the purpose of the plastic bag, and desirably, the vacuum pump 500, the heater 600 and the digital control unit 800 are housed in the lower casing 300. The upper casing 200 is pivoted by the lower casing 300 in such a manner as to be open...
