Abstract

Disclosed herein is a soundproof blender having an automatic cover. The blender includes: a main body on which a container receiving a processing object is seated; and a cover disposed to surround at least a portion of the container, wherein the cover automatically opens or closes at least a portion of the container.

First claim

The invention claimed is:

1 . A soundproof blender having an automatically opening and closing cover, comprising:
a main body on which a container receiving a processing object is seated; a cover disposed to surround at least a portion of the container, wherein the cover automatically opens or closes at least a portion of the container; a main body actuator disposed inside the main body and providing power for processing the processing object inside the container; a cover actuator controlling an opening/closing operation of the cover; a controller controlling the main body actuator and the cover actuator in an operatively connected manner, wherein the controller is configured to control at least one of:
a first operation including moving the cover to a closed position and initiating a processing operation inside the container by controlling the cover actuator and the main body actuator; and
a second operation including stopping an operation of the main body actuator and moving the cover to an open position by controlling the cover actuator and the main body actuator; and
a quick switch transmitting a signal for initiating at least one of the first operation and the second operation to the controller, wherein the quick switch includes a one-touch button transmitting a signal by detecting a user's touch, a voice recognition device transmitting a signal by detecting a user's voice, and a container recognition device detecting whether the container is seated on the main body.

2 . The blender according to claim 1 , wherein the second operation includes at least one of:
operating the cover actuator after stopping operation of the main body actuator; operating the cover actuator while stopping operation of the main body actuator; and stopping operation of the main body actuator after operating the cover actuator.

3 . The blender according to claim 1 , wherein the controller is configured to initiate the second operation when at least one of the following occurs:
operation of the main body actuator is completed while meeting preset requirements; and an error is detected during operation of the main body actuator.

4 . The blender according to claim 1 , further comprising:
a vacuum motor controlling a vacuum in an internal space of the container.

5 . The blender according to claim 4 , wherein the first operation may further include initiating the processing operation inside the container after the cover is moved to the closed position and the internal space of the container is switched to a vacuum state, and
the second operation may further include initiating opening operation of the cover after the processing operation inside the container is completed and operation of the vacuum motor is completed.

6 . The blender according to claim 5 , wherein the controller may control the main body actuator, the cover actuator, and the vacuum motor in an operatively connected manner.

7 . The blender according to claim 1 , wherein the controller rotates the cover to the open position in at least one case of:
when the closing operation of the cover is not completed in a preset amount of time; and when a load of a motor of the cover actuator exceeds a preset range during rotation of the cover to the closed position.

8 . A soundproof blender having an automatically opening and closing cover, comprising:
a main body in which a container receiving a processing object therein is seated; a main body actuator disposed inside the main body and providing power for processing the processing object inside the container; a cover which may open or close, the cover surrounding the container in a closed position; a cover actuator controlling an opening/closing operation of the cover; and a controller controlling the main body actuator and the cover actuator in an operatively connected manner, wherein the cover actuator includes: a rotary body coupled to the cover to be rotatable in association with the opening/closing operation of the cover; an opening/closing detection member including at least one rotation sensor to detect opening/closing of the cover based on a degree of rotation of the rotary body; and a motor generating power to be transmitted to the rotary body.

9 . The blender according to claim 8 , wherein the controller is configured to control a first operation including:
operating the motor to rotate the rotary body; and operating the main body actuator to initiate a processing operation inside the container in response to detecting, by the opening/closing detection member, that the cover is in the closed position.

10 . The blender according to claim 9 , wherein when the closing operation of the cover is stopped for a preset amount of time during the first operation before the cover is detected to be in the closed position by the opening/closing detection member, the controller operates the motor to rotate the rotary body until the cover is detected to be in the open position by the opening/closing detection member.

11 . The blender according to claim 9 , wherein when at least one of the following occurs: the first operation is completed while meeting preset requirements;
and an operational error of the main body actuator is detected, the controller is configured to control a second operation including stopping operation of the main body actuator and operating the motor to rotate the rotary body until the cover is detected to be in the open position by the opening/closing detection member.

12 . The blender according to claim 8 , wherein the cover actuator further includes a torque supplementation member supplementing the power of the motor during the opening/closing operation of the cover.

13 . The blender according to claim 12 , wherein the torque supplementation member includes an inflection region defined as a compression position of an elastic body in which the cover is maintained in a stationary position between the open position and the closed position of the cover, and
wherein when the compression position of the elastic body is out of the inflection region, the rotary body is rotated to move the cover to the open position or the closed position.

14 . The blender according to claim 12 , wherein the torque supplementation member includes at least one elastic body,
wherein, when the cover is in the open position or the closed position, the elastic body is maintained in a compressed position and, during the opening/closing operation of the cover, the elastic body is released from the compressed position.

15 . The blender according to claim 11 , further comprising:
a quick switch transmitting a signal for initiating at least one of the first operation and the second operation to the controller, wherein the quick switch is disposed on the upper surface of the main body.

16 . A soundproof blender having an automatically opening and closing cover, comprising:
a main body in which a container receiving a processing object therein is seated; a main body actuator disposed inside the main body and providing power for processing the processing object inside the container; a cover which may open or close, the cover surrounding the container in a closed position; a cover actuator controlling an opening/closing operation of the cover; and a vacuum motor making an internal space of the container into a vacuum state; wherein the cover actuator includes: a rotary body coupled to the cover to be rotatable in association with the opening/closing operation of the cover; and a motor generating power to be transmitted to the rotary body, and whe
