Hereinafter, the operating state of the control unit 500 will be described with reference to FIGS. 1 to 9 . Here, the control unit 500 operates the rotating unit 400 and the main body driving unit 110 to start the processing operation inside the container 200 in the state in which the first cover 310 is closed. Defined by Meanwhile, the control unit 500 controls the operation of the body drive unit 110 and the rotation unit 400 to open the first cover 310 when the processing operation inside the container 200 is completed as a second operation. define.

The control unit 500 may control the operation of the main drive unit 110 and the operation of the rotation unit 400 in connection with each other, or may control the operation of the main drive unit 110, the rotation unit 400, the vacuum driving unit 600, and the suction driving unit. All operations of 900 can be linked and controlled. For example, the controller 500 may control at least one of the first operation and the second operation.

The control unit 500 may control a first operation such that a processing operation inside the vessel 200 is started in the closed state of the first cover 310 by operating the rotation unit 400 and the body driving unit 110. there is.

The control unit 500 controls the operation of the main body drive unit 110 and the rotation unit 400 to perform a second operation such that the first cover 310 is opened when the processing operation inside the container 200 is completed. You can control it. For example, the control unit 500 may operate the rotating unit 400 after stopping the operation of the main body driving unit 110, or operate the rotating unit 400 while stopping the operation of the main body driving unit 110. Alternatively, after operating the rotation unit 400, the operation of the body driving unit 110 may be stopped. For example, during the second operation, the operation sequence of the body drive unit 110 and the rotation unit 400 by the control unit 500 may be set in advance or may be changed by the user.

That is, the user manipulates the above-described control unit 10, for example, presses a button, sends a voice signal, sends a communication signal through an electronic terminal, or places the container 200 by a container recognition device described later. Whether or not is detected, or when the container 200 is seated on the main body and a preset time elapses, the first cover 310 rotates to change from the open state to the closed state, and then the processing operation inside the container 200, that is, , It is possible to increase the user's work efficiency by allowing the blade to rotate so that the operation of crushing the food material can proceed automatically.

Meanwhile, the controller 500 operates the opening operation of the first cover 310 when the closing operation of the first cover 310 is not completed for a preset time during the first operation before the closed state of the first cover 310. can initiate. For example, while the first cover 310 rotates in a closed state for the first operation, the user's hand is caught between the first cover 310 and the main body 100. When the rotation of 0.1 second to 1 minute, for example, between 1 second and 5 seconds is stopped or between 0.1 second and 1 minute, for example, between 1 second and 5 seconds, when the closed state is not completed, the first cover 310 can rotate in an open state. For example, when the load of the rotation motor 440 of the rotation unit 400 is out of a preset range while the first cover 310 rotates in the closed state, the first cover 310 may rotate in the open state. there is.

Accordingly, in a situation in which the first cover 310 cannot be rotated in a closed state, an overload of the rotation motor 440 or a safety accident, which will be described later, can be eliminated.

In addition, the control unit 500 may start the second operation in at least one of cases where the operation of the main body driving unit 110 is completed under a preset condition and when an error is detected during operation of the main body driving unit 110. can For example, the preset condition may include operation of the main body driving unit 110 for a preset grinding time, completion of operation according to a cooking recipe setting, and the like, and the following is the same. For example, the operation error may include detecting an overload of the body drive unit 110 during the first operation or detecting separation of the container 200 from the body drive unit 110 .

Accordingly, when the user inputs a single operation signal to the control unit 10, the first cover 310 is rotated in a closed state and an operation of crushing the food material proceeds. ) is stopped and the process of rotating the first cover 310 in an open state is linked, so that the user can easily check whether the processing operation is finished even in a noisy home or commercial facility, and the container can be safely and quickly By being able to take it out, efficiency in use can be greatly improved. At the same time, if a problem occurs during the processing operation of the food material in a situation where it is difficult for the user to check, the processing operation is automatically stopped and the first cover 310 is rotated in an open state to prevent damage to the product and to ensure safety in use. can be secured

For example, the controller 500 may control at least one of the first operation and the second operation including the operation of the vacuum driving unit 600 .

At this time, the first operation may further include rotating the first cover 310 in a closed state and starting a processing operation inside the container 200 after the inner space of the container 200 is in a vacuum state. In addition, the second operation indicates that the opening operation of the first cover 310 is started in a state in which the processing operation inside the container 200 is completed according to the above-described preset conditions and the operation of the vacuum driving unit 600 is completed. can include more. For example, the state in which the operation of the vacuum driver 600 is completed refers to a state after the inner space of the container 200 becomes a vacuum state under a preset vacuum condition, and the inner space of the container 200 returns to a vacuum state. It may be a maintained state or a state in which the vacuum in the inner space of the container 200 is released. That is, the second operation is a state in which the inner space of the container 200 is maintained in a vacuum state or the vacuum in the inner space of the container 200 is released after the processing operation inside the container 200 is completed according to the above-described preset conditions. It may include starting the opening operation of the first cover 310 in the state.

Accordingly, when the user inputs a single operation signal to the operation unit 10 while allowing the grinding of the food material to proceed inside the container 200 in a vacuum state, the above-described first operation and the second operation proceed in conjunction, resulting in improved efficiency in use. can be greatly improved.

Hereinafter, referring to FIGS. 5 and 6 , the operating state of the pivoting part 400 will be described.

The rotation unit 400 includes a first rotation body 411, a second rotation body 412, a torque auxiliary member 420, a sensor unit 430, a rotation motor 440, a motor gear box 450, and a drive It includes all or part of the transmission member 460 and the gearbox 470.

The first rotational body 411 and the second rotational body 412 are coupled to the rotation groove 312 of the first cover 310 and can rotate together according to the opening and closing operation of the first cover 310 . For example, the first rotational body 411 and the second rotational body 412 are fixed to the first cover 310, and the first rotational body 411 and the second rotational body 412 rotate. One cover 310 can rotate up and down.

For example, the first rotatable body 411 and the second rotatable body 412 are connected to the first rotatable body 411 and the drive transmission member 460 spaced apart from a drive transmission member 460 to be described later. (412). Here, connection means a state in which the power of the rotation motor 440 can be provided within the rotation unit 400, and separation means a state in which the rotation force of the rotation motor 440 is not provided within the rotation unit 400. means

For example, when the gearbox 470 is disposed between the second rotational body 412 and the drive transmission member 460, the power of the rotational motor 440 is provided to the drive transmission member 460, and then the gearbox Since it is provided as the second rotatable body 412 after being provided as the 470, the driving transmission member 460 and the second rotatable body 412 can be described as being connected. That is, the power of the rotational motor 440 is transmitted to the second rotational body 412, and the first cover 310 rotates according to the rotation of the second rotational body 412, and the first cover 310 is centered. As a reference, a structure in which the first rotational body 411 located on the opposite side of the second rotational body 412 rotates together with the rotation of the first cover 310 may be applied.

The torque auxiliary member 420 may assist the force required to open and close the first cover 310 . The blender 1 may be applied with a first cover 310 having a predetermined or more weight in order to increase the noise blocking effect. As the torque auxiliary member 420 is applied, the user manually uses a small amount of force to manually remove the first cover 310. ), or the first cover 310 can be opened and closed by less power of the rotation motor 440 .

The sensor unit 430 may detect an open state and a closed state of the first cover 310 .

The sensor unit 430 includes at least one sensor disposed on the PCB 433 and can detect the open state and the closed state of the first cover 310 according to the radius of rotation of the rotating bodies 411 and 412. there is.

For example, the first sensor 431 and the second sensor 432 may include microswitches.

For example, the sensor unit 430 includes the first sensor 431, the second sensor 432, and a fluid moving therebetween based on rotation of the first rotating body 411 and the second rotating body 412 ( 434) may be included. For example, when the fluid 434 moves to the position of the first sensor 431, that is, moves upward and presses the first sensor 431, the controller 500 determines that the lower surface of the first cover 310 is the main body. It is recognized that the space defined between the second cover 320 and the main body 100 is closed by being in contact with the unit 100, and the fluid 434 moves to the position of the second sensor 432, that is, , When the second sensor is pressed while moving downward, it may be recognized that the first cover 310 is in a maximum open state.

The rotation motor 440 may generate power to be transmitted to the second rotation body 412 . For example, the power of the rotational motor 440 may be directly transmitted to the second rotational body 412, or after the power of the rotational motor 440 is controlled through the motor gearbox 450, the second rotational body (412). For example, the rotation motor 440 may be mounted in the main body 100 .

The drive transmission member 460 is disposed between the second rotational body 412 and the motor gearbox 450, and may transmit power of the rotational motor 440 to the second rotational body 412. In this case, the control unit 500 may control the drive transmission member 460 to control whether power of the rotation motor 440 is transmitted to the second rotation body 412 .

For example, an electronic type may be applied to the drive transmission member 460, and, for example, an electronic clutch using electromagnetic force may be applied. For example, the electronic clutch may be provided with a connecting portion 461, which is a part that is in contact with or separated from each other to transmit or release power. The connection part 461 includes a member or space having a structure in which at least a part is spaced apart when power is not transmitted.

At this time, the electronic clutch may be designed to have a structure in which the connection part 461 is normally spaced apart. Accordingly, the second rotation body 412 is separated from the rotation motor 440 so that the user can easily rotate the first cover 310 .

At this time, the electronic clutch may be designed to have a structure in which the connecting portion 461 is connected when energized. Accordingly, the second rotation body 412 is connected to the rotation motor 440 so that the first cover 310 can be rotated by driving the rotation motor 440 .

At this time, the sensor unit 430 may be connected to the first rotational body 411 . Accordingly, even when the rotational motor 440 is driven and power is provided to the second rotational body 412, but the first cover 310 does not rotate due to damage to the second rotational body 412, the first cover The open/closed state of (310) can be accurately sensed.

The rotation unit 400 may further include a motor gearbox 450 and a gearbox 470 .

The motor gear box 450 may be connected to the rotation motor 440 and control power of the rotation motor 440 transmitted to the second rotation body 412 .

The gearbox 470 may provide power of the rotational motor 440 to the second rotational body 412 disposed on an axis different from the axis on which the rotational motor 440 is disposed. At this time, the other axis includes both parallel and non-parallel to the comparison target axis. That is, the blender 1 may be disposed in a space where the rotation part 400 is closed by the second cover 320 and the first cover 310 to provide a compact design, and the rotation motor 440 When positioned on the same axis as the first rotating body 411 and the second rotating body 412, interference between the rotating part 400 and the container 200 may occur or a compact design may not be achieved. Therefore, the blender 1 can achieve a compact design by improving space utilization efficiency by applying a gearbox 470 for arranging the power of the rotation motor 440 on a different axis from the rotation motor 440.

On the other hand, in the blender 1, the operation of the body drive unit 110 and the rotation unit 400 are linked, so that the user couples the container 200 to the top of the body unit 100 and then sends an operation signal to the control unit 10 only once. If input, the above-described first operation and second operation may be automatically performed. The operation signal, as described above, is a button press, a voice signal, a communication signal by an electronic terminal, or whether the container 200 is seated or not is detected by a container recognizing device described later, or the container is moved to the main body. It may include a case where a preset time elapses after being placed on the bed.

That is, the control unit 500 operates the rotation motor 440 so that the second rotation body 412 rotates, and when the sensor unit 430 detects that the first cover 310 is in a closed state, the body drive unit By actuating 110, a first operation of initiating a processing operation inside the container 200 may be controlled.
