Vacuum blender

A vacuum blender comprising:

• a driving body, in which a motor is mounted on an interior thereof;
• an accommodation member detachably coupled to an upper portion of the driving body and having a first chamber part configured to accommodate foods in an interior thereof;
• a cutter blade disposed in the first chamber part and connected to the motor to blend the foods accommodated in the first chamber part;
• a cover member detachably coupled to the driving body while covering an outside of the accommodation member;
• and
• a first check valve mounted on the accommodation member and configured to be opened only when air is discharged from the first chamber part to an outside by selectively communicating the first chamber part and an interior of the cover member;
• a second chamber part formed along a circumference of the accommodation part between the outside of the accommodation member and the interior of the cover member;
• and
• a second check valve mounted on the cover member and configured to be opened only when air is discharged from the second chamber part to the outside by selectively communicating the outside of the second chamber part,
• wherein when a vacuum pump is operated in a state in which a suction hose of the vacuum pump disposed on the outside is coupled to the second check valve, the air in an interior of the second chamber part is discharged to the outside through the second check valve and the vacuum pump, the first check valve is opened by a vacuum pressure, and the air in an interior of the first chamber part is discharged to the outside through the vacuum pump via the first check valve, the second chamber part, and the second check valve, and
• as exterior air is introduced into the second chamber part, the first check valve is closed and the first chamber part maintains a vacuum state while the vacuum state is not released, and
• the vacuum state of the interior of the first chamber part is released through the first check valve.

A vacuum blender comprising:

• a driving body, in which a motor is mounted on an interior thereof having a first chamber part configured to accommodate raw foods in an interior thereof;
• an accommodation member detachably coupled to an upper portion of the driving body and having the first chamber part configured to accommodate the raw foods in the interior thereof;
• a cutter blade disposed in the first chamber part and connected to the motor to blend the raw foods accommodated in the first chamber part;
• a cover member detachably coupled to an upper portion of the driving body while covering an entire outside of the accommodation member and defining a second chamber part along an upper portion and a circumference of a side surface of the accommodation member between the cover member and the outside of the accommodation member;
• a first check valve mounted in a first discharge hole formed in the accommodation member and configured to selectively communicate the first chamber part and the second chamber part by opening and closing the first discharge hole;
• and
• a second check valve mounted in a second discharge hole formed in the cover member and configured to selectively communicate the second chamber part and an outside by opening and closing the second discharge hole,
• an impact absorbing member, one end of which contacts an outer peripheral surface of the accommodation member and an opposite end of which contacts an inner peripheral surface of the cover member such that vibration of the accommodation member is reduced,
• wherein the accommodation member is disposed inside the second chamber part while being spaced apart from the cover member,
• wherein the first check valve opens the first discharge hole by an external force to communicate the first chamber part and the second chamber part,
• wherein the second check valve interrupts the communication of the second chamber part and the outside by closing the second discharge hole in a free state, and communicates the second chamber part and the outside by opening the second discharge hole by an external force,
• wherein the first chamber part is vacuumed as the first check valve opens the first discharge hole by a vacuum pressure while the second chamber part is vacuumed by an operation of the vacuum pump communicated with the second chamber part,
• wherein when the second discharge hole is opened by the second check valve in a state in which the first chamber part and the second chamber part are vacuumed, a vacuum state of the second chamber part is released as exterior air is introduced, and the first check valve closes the first discharge hole by a vacuum pressure of the first chamber part such that the first chamber part maintains a state in which the first chamber part is vacuumed independently from the second chamber,
• wherein the absorbing member is coupled to an inner peripheral surface of the cover member,
• wherein the absorbing member is spaced apart from an outer peripheral surface of the accommodation member in a state in which the second chamber part is not vacuumed, and
• wherein when the second chamber part is vacuumed, the impact absorbing member is adhered to an outer peripheral surface of the accommodation member while the cover member is moved toward the accommodation member by a vacuum pressure.
