Embodiment Construction

[0014] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0015] Figure 1a is a front view of an exemplary vacuum apparatus for storing food storage containers under vacuum to which the inventive method is applied, and Figure 1b Yes Figure 1a A side view of the vacuum device 10 is shown. The vacuum device 10 includes a main body 12 having a vacuum chamber therein and a machinery room 14 . In the machine room 14, a vacuum pump and the like are installed.

[0016] A vacuum application line connecting the vacuum chamber to a vacuum pump and a vacuum release line connecting the vacuum chamber to air extend from the vacuum chamber in the main body 12 to the machine room 14 . A Peltier element using the Peltier effect may be provided in the vacuum application line to remove moisture introduced into the vacuum pump. This Peltier element works with a vacuum pump. A sealing arrangement is provided between...

Abstract

The present invention relates to a pressure control method suitable for devices such as a vacuumizer for use with containers for storing food under vacuum. The inventive method comprises a step of determining a first referential pressure and a second referential pressure, wherein the first referential pressure has a level between a preset vacuum pressure and an atmospheric pressure and the second referential pressure has a level between the preset vacuum pressure and the first referential pressure, a step of determining a target pressure of the vacuum chamber from information inputted by the user, a step of operating the evacuation means for the reduction of the pressure, a step of measuring duration time that it takes for the pressure within the vacuum chamber to reach the second referential pressure from the first referential pressure, a step of determining additionally required time that it takes for the pressure within the vacuum chamber to reach the target pressure from the second referential pressure based on the duration time, and a step of further operating the evacuation means for the additionally required time and then stopping the operation of the evacuation means.

Description

technical field [0001] The present invention relates to a pressure control method, and more particularly, to a pressure control method of a device such as a vacuum device suitable for a container for storing food under vacuum. Background technique [0002] A vacuum device for a container storing food under vacuum as described above is disclosed in Korean Patent Application No. 10-2001-0029590. The vacuum device includes an opening, a door installed near the opening for opening and closing the container, a vacuum chamber in which a container for keeping food under vacuum is accommodated, and an evacuating member connected to the vacuum chamber for evacuating the vacuum chamber . In the vacuum device configured in this way, when the user inputs information on the condition of preserving food, a target pressure value is determined and then the vacuuming action is completed. [0003] In the pressure control process of changing the pressure in the vacuum chamber to a target pre...
