panel 17 is electrically connected to the controller so as to receive information regarding components of thevacuum source 20 and show same in operation. Also, thepanel 17 comprises a plurality of buttons for operating the vacuum sealer. - A
transparent clamping door 30 pivotally mounted on the front portion of thebase housing 10 by being hingedly secured to a rear end of theplatform 11 and comprises ahandle 31 on top, acorresponding heating element 32 adjacent to a front bottom edge, and an ovalcorresponding sealing strip 33 formed of rubber and disposed behind thecorresponding heating element 32. Thecorresponding heating element 32 is also electrically connected to the timing circuit. - A
drip pan 40 is shaped as an oval. Thedrip pan 40 comprises abossed hole 41 on abottom 43, aperipheral flange 42, and two spacedrisers 44 on thebottom 43. Thedrip pan 40 can be removably complimentarily disposed in therecess 13 with theflange 42 rested upon the top edge of therecess 13 and thehole 41 put on thevacuum inlet 14. - A
hollow tubing 50 is interconnected thevacuum inlet 14 and thevacuum pump 21 via a electromagnetic valve for fluid communication. - An operation of the invention will be discussed in detail below. An individual may open the
clamping door 30 by lifting thehandle 31, place an open portion of theplastic bag 60 on theplatform 11, and align anopening 61 of aplastic bag 60 with the front end of theflange 42 in which theplastic bag 60 is stored with food containing liquids and both theheating element 12 and thesealing strip 15 are engaged with the plastic bag 60 (seeFIG. 3 ). Next, the individual may pivot down the clampingdoor 30 to tightly engage thecorresponding heating element 32 with theheating element 12 and tightly engage thecorresponding sealing strip 33 with thesealing strip 15 respectively (seeFIG. 4 ). Thus, an airtight space is formed and defined by thedrip pan 40, thesealing strip 15, and thecorresponding sealing strip 33. The individual can check whether the opening 61 of theplastic bag 60 is correctly positioned or not by seeing through thetransparent clamping door 30.
