Definitions

  • the present invention relates, in general, to a vacuum sealer having a locking means and, more particularly, to a vacuum sealer, which has a locking means on a hood and a container, thus being capable of creating a vacuum in a desired object without the necessity of pressing the hood, and which is constructed so that a straight line-shaped sealing member, in place of a continuous closed lower rubber packing, is mounted on the container, thus simplifying construction of the container while maintaining the same vacuum level as that of a conventional vacuum sealer, and which allows a vacuum of a vacuum chamber to be easily released after the vacuum operation has been completed, and which is capable of controlling a depth of a vacuum bag inserted between the hood and the container, and which is capable of discharging oil and impurities using an inclined channel provided on an upper surface of the container.

  • the cooling apparatus can preserve food for a predetermined period.
  • the food may rot due to oxidation caused by air existing in the plastic wrap or bag.
  • the cooling apparatus has a problem in that it is difficult to preserve food for a lengthy period of time.
  • a vacuum sealer which is constructed so that foodstuff or cooked food is put into a wrapper, air is exhausted from the wrapper, and the wrapper is sealed, thus preventing the foodstuff or cooked food from being oxidized or deteriorated, therefore allowing the foodstuff or cooked food to be preserved for a lengthy period of time.
  • a conventional vacuum sealer includes a hood and a container 10. Rubber packings 12 and 22 are provided on lower and upper portions of the vacuum sealer to seal an open end of a vacuum bag which is inserted into the hood 20.
  • the vacuum sealer also includes a vacuum pump 14 which draws air from the interior of the vacuu bag 50 in cooperation with the lower and upper rubber packings 12 and 22.
  • a heater 16 is installed in front of the lower rubber packing 12 to heat and seal the vacuum bag 50.
  • the vacuum sealer constructed as described above is operated as follows. That is, a user puts desired food into the vacuum bag 50. The open end of the vacuum bag is placed between the lower and upper rubber packings 12 and 22. Subsequently, the upper rubber packing 22 provided in the hood 20 is pressed over the lower rubber packing 12. In such a state, when a predetermined switch is pressed, the vacuum pump 14 operates. By the operation of the vacuum pump 14, a vacuum is created in a space defined between the rubber packings 12 and 22. If a vacuum bag made of typical vinyl is used, it is impossible to draw air from the interior of the vacuum bag 50 using the lower and upper rubber packings 12 and 22.
  • a switch means is installed at a predetermined position on the container of the heat sealer.
  • the hood having a protrusion which operates the switch means is hinged to the container.
  • the protrusion of the hood comes into contact with the switch means, thus completing an electrical circuit.
  • the supply of electricity is interrupted. Thereby, a user must press the hood over the container while the vacuum bag is sealed. Further, when air is drawn from the interior of the vacuum bag during the vacuum operation, the vacuum bag must contact rubber packings.
  • the conventional vacuum sealer is problematic in that a user must continue to press the hood over the container, thus causing inconvenience to the user.

  • the conventional vacuum sealer has another problem in that the hooks or the hook holes may be broken or damaged due to the impact of the hood contacting the container.
  • the conventional vacuum sealer has a further problem in that an external appearance of the hooks mounted to the hood is poor. Further, the conventional vacuum sealer is not provided with an impurity removal means to remove oil or impurities from the vacuum bag. Thus, oil or impurities may undesirably flow into the vacuum pump, so that the pumping capacity of the vacuum pump is deteriorated and the vacuum pump may malfunction. Further, the conventional vacuum sealer is problematic in that an external force must be applied to separate the upper and lower packings from each other, after the vacuum operation is completed. Further, Korean Patent No. 109619 has been proposed, which is entitled "apparatus for vacuum sealing plastic bag". According to the patent, the apparatus is provided with upper and lower vacuum chamber means which may remove impurities.
  • the apparatus also includes upper and lower rubber packings.
  • the upper and lower vacuum chamber means define a vacuum chamber.
  • the vacuum bag when a vacuum is created in the vacuum bag after food having no water or impurities is put into the vacuum bag, air is drawn out of the vacuum chamber means by the vacuum pump and then air is exhausted from the vacuum bag. Thus, it takes a longer time to evacuate the vacuum bag. Meanwhile, when food contains a large amount of impurities, the impurities may overflow the lower vacuum chamber means, so that the impurities may flow into the vacuum sealer. Further, the conventional vacuum sealer is problematic in that impurities must be removed from the lower vacuum chamber means whenever the vacuum operation is completed, so that it is complicated to use.

Abstract

Il s’agit d’un colmatant pour aspirateur verrouillable. Ce colmatant pour aspirateur possède des moyens de verrouillage (90), évacuant ainsi les objets sans l’aide de la hotte. En outre, un élément colmatant en forme de ligne droite est disposé sur un conteneur, simplifiant ainsi la construction du conteneur. Le colmatant pour aspirateur permet une évacuation plus aisée de la chambre à dépression, en supplément du contrôle de la profondeur d’encastrement d’un sac sous vide et du déversement de l’huile et des impuretés par le biais d’un canal incliné. Ce colmatant pour aspirateur inclut le conteneur (10) doté d’un élément colmatant et d’un réchauffeur.
