Abstract

Disclosed in the present invention is a low-temperature cooking machine. The low-temperature cooking machine comprises a flexible heating unit and a pump, and the pump is used for providing pressure or suction to cause the flexible heating unit to deform and contact and heat food. The low-temperature cooking machine in the present invention is a novel cooking device; under the action of the pump, the flexible heating unit as a heater can be deformed and directly contact food, so as to directly heat and cook the food. The low-temperature cooking machine in the present invention is a novel device and can replace an existing low-temperature cooking device having a constant temperature water bath and a vacuum plastic package machine.

First claim

What is claimed is:

1. A low-temperature cooking machine, comprising:
a flexible heating unit; and
a pump for providing pressure or suction to cause the flexible heating unit to deform and contact with and heat a food;
an upper cover pivotally mounted on a base; and
a food cooking cavity for receiving the food, wherein the flexible heating unit comprises a liquid heating bag connected with a water heater, the flexible heating unit comprises an upper flexible heating unit and a lower flexible heating unit, the upper flexible heating unit is arranged in an upper cover cavity of the upper cover, and the upper cover cavity is divided by the upper flexible heating unit into an upper medium storage area and an upper food cooking cavity; a base cavity of the base is divided by the lower flexible heating unit into a lower food cooking cavity and a lower medium storage area, wherein the lower food cooking cavity, the lower flexible heating unit and the lower medium storage area are sequentially arranged in a separated manner from top to bottom in the base cavity; the upper medium storage area, the upper flexible heating unit and the upper food cooking cavity are sequentially arranged in a separated manner from top to bottom in the upper cover cavity.

2. The low-temperature cooking machine according to claim 1 , wherein the flexible heating unit at least partially surrounds the food cooking cavity,
wherein the food cooking cavity is a closed chamber, the pump is an air pump for vacuuming the food cooking cavity, and the flexible heating unit is in close contact with and heats the food under vacuum suction.

3. The low-temperature cooking machine according to claim 2 , wherein the flexible heating unit is arranged around the food cooking cavity, or the flexible heating unit is at least arranged at two sides of the food.

4. The low-temperature cooking machine according to claim 2 , further comprising the base wherein the flexible heating unit is arranged in the base cavity of the base, and the food cooking cavity is formed in the base cavity; wherein the food is able to be put into the food cooking cavity when the upper cover is pivotally opened, and the upper cover encloses the food cooking cavity when the upper cover is pivotally closed.

5. The low-temperature cooking machine according to claim 4 , wherein the flexible heating unit is arranged on an inner side of the upper cover.

6. The low-temperature cooking machine according to claim 1 , further comprising a flexible medium storage unit connected with a medium pipe, wherein the pump is a pressurizing pump for pumping a pressurized medium toward the flexible medium storage unit through the medium pipe, and the flexible heating unit is pushed by a boosted pressure of the flexible medium storage unit to closely contact with and heat the food.

7. The low-temperature cooking machine according to claim 6 , further comprising the base, wherein the flexible heating unit, the flexible medium storage unit and the food cooking cavity for receiving the food are arranged in the base cavity of the base, the flexible heating unit at least partially surrounds the food cooking cavity, and the flexible medium storage unit is able to at least partially contact with the flexible heating unit.

8. The low-temperature cooking machine according to claim 7 , wherein the flexible medium storage unit comprises a medium storage bag.

9. The low-temperature cooking machine according to claim 7 , wherein the base cavity is divided by the flexible heating unit into the food cooking cavity and a medium storage area serving as the flexible medium storage unit.

10. The low-temperature cooking machine according to claim 9 , wherein the medium storage area, the flexible heating unit and the food cooking cavity are transversely and sequentially arranged in a separated manner in the base cavity, and the upper cover covers the base to enclose the medium storage area.

11. The low-temperature cooking machine according to claim 6 , wherein the food cooking cavity is an enclosed chamber provided with an exhaust passage.

12. The low-temperature cooking machine according to claim 11 , wherein a non-return exhaust valve is arranged in the exhaust passage.

13. The low-temperature cooking machine according to claim 12 , wherein the medium pipe is an air intake passage, and the pump is an air pump that blows air to the flexible medium storage unit through the air intake passage.

14. The low-temperature cooking machine according to claim 1 , further comprising an air pump controller for monitoring an amount of air in the food cooking cavity.

15. The low-temperature cooking machine according to claim 1 , further comprising a heating controller for monitoring a heating temperature of the flexible heating unit.

16. The low-temperature cooking machine according to claim 15 , wherein the flexible heating unit comprises a thermostatically controlled heating unit.

17. The low-temperature cooking machine according to claim 1 , wherein a cooking temperature of the low-temperature cooking machine is 60-80° C.
