On the other hand, under the cleaning mode, the food support 50 may be automatically moved upward or downward.

On the other hand, the drive unit 230 includes a drive motor 110 for moving at least the food support unit 50 up and down. The drive motor 110 is operated differently according to the selected mode.

That is, when the automatic mode is selected, the driving motor 110 is operated for a predetermined time under the control of the controller 200. At this time, the predetermined time may be detected by a timer.

Here, the food support 50 may be moved to a height corresponding to the food to be cooked at the reference position. That is, when cooking of the previous food is completed, the food support 50 may be moved to a reference position, and when cooking of the new food, the food support 50 may be moved to a height corresponding to the new food. In this case, the driving time of the driving motor 110 may be as long as a reference time corresponding to each food.

Alternatively, the food support 50 may be moved from the height at the time of cooking the previous food to the height corresponding to the new food. In this case, the driving time of the driving motor 110 may be as much as the difference between the reference time corresponding to the old food and the reference time corresponding to the new food.

In the present embodiment, the driving motor 110 is configured to be driven by a timer for a time corresponding to each food under the automatic mode.

That is, although the coupling positions of the respective link members 332 and 334 and the driving gear 320 are different from each other, the upper link member 352 is bent a plurality of times in the downward direction, so that the link member 332 and the driving gear 320 are connected to the second driven gear 352. The engagement height is equal to the engagement height of the first driven gear 342.

In addition, since the link members 332 and 334 are configured to move in opposite directions, the rotation directions of the supporters 344 and 354 interacting with the link members 332 and 334 are also different from each other. The opposite is true.

The operation of the vertical movement device 300 constituting the above-described configuration will be described.

First, in order to move the food support 50 upward, the drive motor 310 is rotated in the clockwise direction, the drive gear 320 coupled to the drive motor 310 is also rotated in the clockwise direction. . When the driving gear 320 is rotated in the clockwise direction, the lower link member 332 is moved to the left and the upper link member 334 is moved to the right.

In addition, when the lower link member 332 is moved to the left side, the first driven gear 342 is rotated clockwise and the first supporter 344 coupled thereto is rotated clockwise. When the upper link member 352 is moved to the right, the second driven gear 352 is rotated in the counterclockwise direction, and the second supporter 354 coupled thereto is rotated in the counterclockwise direction.

In addition, the food support 50 is moved upward by the clockwise rotation of the first supporter 344 and the counterclockwise rotation of the second supporter 354.

On the other hand, the lower movement of the food support 50 is opposite to the upper movement, a detailed description thereof will be omitted.

As described above, the present embodiment is configured to enable vertical movement of the food support unit 50 while the supporters 344 and 354 are rotated in the same manner as the original embodiment.

However, in the present embodiment and the leg embodiment, each of the supporters 344 and 354 is not directly rotated by the drive motor 310, but a transfer unit that transfers the driving force of the drive motor 320, that is, the drive. It is configured to rotate by the gear 320, the link member 330 and the driven gear 342, 352.

Therefore, as the food support unit 50 is configured to move up and down by the plurality of supporters 344 and 354, the food support unit 50 may be moved up and down more stably.

10 is a view showing the structure of the vertical movement apparatus according to the fifth embodiment of the present invention.
