Food vacuum sealing cabinet
View Patent ↗A food vacuum sealing cabinet provides a system for storing multiple food items in a common vacuum environment to maintain freshness. The cabinet resembles a standard kitchen cabinet but incorporates vacuum technology to create vacuum conditions inside the cabinet when sealed. A vacuum pump, control circuit, and valve system allow users to create vacuum storage conditions with simple button controls and to release the vacuum when access to stored items is needed. The cabinet features connections for vacuum jar and bag attachments, providing multi-functionality beyond cabinet storage. This system eliminates the need for individual vacuum bags or containers while extending the shelf life of dry goods and preventing spoilage.
1 . A food vacuum sealing cabinet comprising:
a cabinet housing similar in size to a standard kitchen cabinet;
a door mounted on hinges attached to said cabinet housing;
an airtight gasket positioned between said door and said cabinet housing; at least one shelf positioned within said cabinet housing forming at least one storage compartment;
a vacuum generation system comprising:
a vacuum pump;
a control circuit connected to said vacuum pump;
a power supply connected to said control circuit;
at least one control input for activating and deactivating said vacuum pump; and
at least one solenoid valve to release vacuum from said cabinet housing;
wherein said cabinet housing, said door, and said airtight gasket form an airtight enclosure when said door is closed; and
wherein said vacuum pump is configured to remove air from said airtight enclosure to create vacuum storage conditions for food items placed within said at least one storage compartment; and
wherein said cabinet housing is configured to operate at ambient room temperature without any refrigeration or cooling mechanism; and
wherein said cabinet housing is configured to maintain food items exclusively through vacuum preservation at ambient room temperature, including a vacuum connector port accessible from outside said cabinet housing and configured for detachable connection, vacuum tubing connected to said vacuum connector port, and at least one vacuum attachment device selected from the group consisting of a vacuum jar storage attachment and a vacuum bag storage attachment, said at least one vacuum attachment device being selectively connectable to said vacuum tubing; and
further comprising a selector switch configured to direct vacuum from said vacuum pump selectively to either said cabinet housing, said at least one vacuum attachment device, or neither said cabinet housing nor said at least one vacuum attachment device; and
a three-way solenoid valve connected to said vacuum pump, said cabinet housing, and at least one vacuum output connection, wherein said three-way solenoid valve is configured to selectively direct vacuum from said vacuum pump to either said cabinet housing for creating vacuum storage conditions for multiple food items simultaneously or to said at least one vacuum output connection for vacuum sealing operations external to said cabinet housing.
2 . The food vacuum sealing cabinet of claim 1 , wherein
at least one vacuum attachment device comprises a vacuum jar storage attachment configured to create vacuum conditions in food storage jars, and wherein said selector switch is configured to direct vacuum from said vacuum pump selectively to either said cabinet housing or said vacuum jar storage attachment.
3 . The food vacuum sealing cabinet of claim 1 , further comprising a selector switch configured to direct vacuum from said vacuum pump selectively to either said cabinet housing or said at least one vacuum attachment device, wherein said at least one vacuum attachment device comprises a vacuum storage attachment configured to create vacuum conditions in food storage bags, wherein said vacuum bag storage attachment remains connected to said vacuum tubing during vacuum bag sealing operations.
4 . The food vacuum sealing cabinet of claim 1 , wherein said at least one vacuum attachment device comprises both a vacuum jar storage attachment configured to create vacuum conditions in food storage jars and a vacuum bag storage attachment configured to create vacuum conditions in food storage bags, wherein said vacuum bag storage attachment remains connected to said vacuum tubing during vacuum bag sealing operations, and wherein said selector switch is further configured to direct vacuum from said vacuum pump selectively to said cabinet housing, said vacuum jar storage attachment, or said vacuum bag storage attachment.
5 . The food vacuum sealing cabinet of claim 1 , further comprising a pressure sensor configured to monitor vacuum pressure within said cabinet housing and provide feedback to said control circuit, wherein said control circuit is configured to automatically control said vacuum pump based on pressure readings from said pressure sensor to maintain a target vacuum level within said airtight enclosure.
6 . The food vacuum sealing cabinet of claim 1 , wherein said three-way solenoid valve receives a single vacuum input connection from said vacuum pump and distributes vacuum to one of three vacuum output connections based on a position of said selector switch, said three vacuum output connections comprising a first output to said cabinet housing, a second output to said vacuum jar storage attachment, and a third output to said vacuum bag storage attachment.
