Abstract

A vacuum cooking appliance is provided. The vacuum cooking appliance may include a housing in which a housing mount and a vacuum packing module mount may be located at adjacent positions, a first container configured to accommodate liquid inside an accommodation space therein and coupled to the container mount, a heater configured to heat the liquid accommodated inside the first container, a vacuum pressure generator installed at the vacuum packing module mount and configured to suction air inside a food packing container, and a vacuum packing module installed adjacent to the vacuum pressure generator and including a sealer configured to heat and seal the food packing container.

First claim

What is claimed is:

1. A vacuum cooking appliance, comprising:
a housing in which a container mount and a vacuum packing module mount are located at adjacent positions;
a first container configured to accommodate liquid inside an accommodation space therein and coupled to the container mount;
a heater configured to heat the liquid accommodated inside the first container;
a vacuum pressure generator installed at the vacuum packing module mount and configured to suction air inside a food packing container;
a vacuum packing module installed adjacent to the vacuum pressure generator and including a sealer configured to heat and seal the food packing container, and
a second container configured to be withdrawable from the accommodation space inside the first container and to accommodate liquid inside the second container, wherein the first container has an open upper portion and is in a hexahedral shape in which the accommodation space configured to accommodate the liquid is formed.

2. The vacuum cooking appliance of claim 1 , wherein the housing is in a frame shape and includes a mounting hole, and wherein the container mount and the vacuum packing module mount are formed to include the mounting hole therein.

3. The vacuum cooking appliance of claim 1 , wherein the second container includes:
a container main body in which a space configured to accommodate the liquid is formed, wherein the container main body is formed in a hexahedral shape having an open upper portion; and
at least one handle installed at a lateral side of the container main body and configured to protrude from and retract into the lateral side.

4. The vacuum cooking appliance of claim 1 , further comprising:
a cover installed at the housing and configured to open and close the open upper portion of the first container.

5. The vacuum cooking appliance of claim 4 , wherein the second container includes:
a container main body in which a space configured to accommodate the liquid is formed, wherein the container main body is formed in a hexahedral shape having an open upper portion; and
a container cover provided to cover the open upper portion of the container main body.

6. The vacuum cooking appliance of claim 5 , wherein a packing bag accommodating space, in which a food packing container is accommodated, is formed between the container cover and the cover.

7. The vacuum cooking appliance of claim 4 , wherein a hinge is installed at one side of the cover to pivotably connect a first side of the cover to the housing, a hook is provided at a second side of the cover, a latch detachably coupled to the hook is installed at the housing, the cover is pivoted based on the first side at which the hinge is installed to open and close the open upper portion of the container main body, and the second side of the cover is separably fixed to the housing through coupling of the hook and the latch.

8. The vacuum cooking appliance of claim 4 , wherein a viewing window configured to view an inside of the first container is formed at the cover.

9. The vacuum cooking appliance of claim 1 , wherein the vacuum pressure generator includes:
a vacuum panel provided to allow an air inlet to be formed and installed at the vacuum packing module mount; and
a vacuum pump configured to generate a vacuum pressure acting on the air inlet.

10. The vacuum cooking appliance of claim 9 , further comprising:
a cover installed at the housing and configured to open and close an open upper portion of the first container, wherein a first seal formed in a closed curve shape enclosing a periphery of the air inlet is installed at the vacuum panel, and a second seal is installed at the cover and engages with the first seal when the cover closes the upper portion of the first container to seal a periphery of the air inlet.

11. The vacuum cooking appliance of claim 1 , wherein the heater is a low-temperature heater configured to heat the liquid accommodated inside the first container at a temperature of about 100° C. or less.

12. The vacuum cooking appliance of claim 1 , wherein the vacuum packing module mount is provided at an upper portion of a front side adjacent to the container mount, and an electronic component space is formed below the vacuum packing module mount, wherein the electronic component space is a space located in front of the first container and is configured to include a region located below the vacuum packing module mounted on the vacuum packing module mount.

13. The vacuum cooking appliance of claim 12 , wherein the first container has an open upper portion and is in a form of a box in which an accommodating space is formed, the vacuum packing module mount is in a shape of a polygonal frame that protrudes forward from the first container, and a bottom surface of the vacuum packing module mount is formed and located above a lower surface of the first container to allow the electronic component space to be formed at a region located below the vacuum packing module.

14. The vacuum cooking appliance of claim 13 , further comprising:
an outer case coupled outside the housing, in which an accommodating space configured to accommodate the housing, the first container, and the electronic component space is formed, and configured to define an outer boundary surface of the electronic component space.

15. The vacuum cooking appliance of claim 1 , further comprising:
a container main body in which an accommodating space for the liquid is formed, the container main body being in a form of a box having an open upper portion; and
a container cover provided to cover the open upper portion of the container main body, wherein a packing bag insertion portion is formed at a vacuum panel, is configured with a concave surface into which an open inlet side of a packing bag is placed, and is formed to allow an air inlet to pass through the packing bag insertion portion, and wherein a seating surface is formed at an upper portion of the container cover to allow a portion of the packing bag to be seated.

16. The vacuum cooking appliance of claim 15 , wherein the seating surface is recessed downward from an edge of the container cover to form a plane located below a plane formed by the packing bag insertion portion.

17. A vacuum cooking appliance, comprising:
a housing in which a container mount and a vacuum packing module mount are located at adjacent positions;
a first container configured to accommodate liquid inside an accommodation space therein and coupled to the container mount;
a second container configured to be withdrawable from the accommodation space inside the first container and to accommodate liquid inside the second container, the second container including a container cover having a seating surface formed at an upper portion thereof to allow a portion of a food packing bag to be seated;
a heater configured to heat the liquid accommodated inside the first container and the second container;
a vacuum pressure generator installed at the vacuum packing module mount and configured to suction air inside the food packing bag;
a vacuum packing module installed adjacent to the vacuum pressure generator and including a sealer configured to heat and seal the food packing bag; and
a cover installed at the housing and configured to open and close an open upper portion of the first container, the cover including a viewing window configured to view an inside of the first container and the second container.

18. A vacuum cooking appliance, comprising:
an outer case configured to accommodate a housing, the housing inclu
