The second vertical movement device 150 includes a pair of second driving motors 160 and 162 provided outside the cavity 20 to generate a driving force, and the second driving motors 160 and 162. A pair of second rotating members 170 and 175 rotated by the two is included.

The second support 140 is coupled to the pair of second rotating members 170 and 175.

In the present embodiment, the pair of vertical movement devices have the same structure and differ in installation positions, so only the first vertical movement device will be described below.

In detail, the driving motors 110 and 112 may include a left driving motor 110 provided outside the first side wall 23 of the cavity 20 (the left wall in FIG. 2), and the first of the cavity 20. The right side drive motor 112 provided on the outer side of the 2 side wall 24 (the right side wall in FIG. 2) is included.

The driving motors 110 and 112 may use a bidirectional motor to allow both directions of the pair of rotating members 120 and 125 to be rotatable. For example, a step motor may be used.

The pair of rotating members 120 and 125 includes a left rotating member 120 and a right rotating member 125. The left and right rotating members 120 and 125 are located inside the cavity 20. In addition, the rotation shaft 122 of the left rotating member 120 penetrates through the left wall 23 of the cavity 20 and is connected to the shaft of the left driving motor 110.

The rotating shaft 126 of the right rotating member 125 penetrates through the right wall 24 of the cavity 20 and is connected to the shaft of the right driving motor 112.

Unlike this, gear teeth are formed on the shafts 122 and 126 of each of the rotating members 120 and 125, and gears are connected to the shafts of the driving motors 110 and 112 so that the driving motors 110 and 112 are formed by the gears. ) May be transmitted to each of the rotating members (120, 125).

Each of the rotating members 120 and 125 has a larger length than the width. In addition, coupling holes 124 and 128 for coupling the support part 130 are formed in the rotation members 120 and 125. In addition, the support 130 is supported by the rotating members 120 and 125 in a state of being coupled to the rotating members 120 and 125.

The coupling holes 124 and 128 are formed at positions spaced apart from the rotation shafts 124 and 126 of the rotation members 120 and 125 by a predetermined distance. In this case, the vertical movement distance of the tray 50 may vary according to the distance between the coupling holes 124 and 128 and the rotation shafts 124 and 128.

Therefore, when the driving motors 110 and 112 are rotated, the respective rotating members 120 and 125 connected to the driving motors 110 and 112 are rotated. In addition, when the rotation members 120 and 125 are rotated, the support 130 rotates about the rotation shafts 122 and 126 of the rotation members 120 and 125.

At this time, since the support 130 is spaced apart from the rotation shafts 122 and 126 of the rotation members 120 and 125, when the support 130 is rotated, the bottom 25 of the cavity 20 is referred to. The height will be different.

Here, when looking at the rotational direction of the supporter relative to the drive motor, the supporter is rotated in one direction with respect to the left drive motor, and in the other direction relative to the right drive motor. That is, each of the drive motors are rotated in the opposite direction. On the contrary, when referring to the direction of viewing the other side from one side of the cavity, the respective driving motors are rotated in the same direction.

Therefore, in the present embodiment, it will be described that each of the driving motors is operated so that the support part 130 rotates in one direction.

3 is a block diagram illustrating a control configuration of the cooking appliance according to the first embodiment.

Referring to FIG. 3, in the cooking apparatus according to the present embodiment, a user may input and output an operation unit 210 for inputting an operating condition of the cooking apparatus and move the tray 50 up and down according to the input condition.

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

That is, when the automatic mode is selected, the driving motors 110 and 112 are operated for a predetermined time under the control of the controller 200. At this time, the predetermined time may be detected by a timer.

In the automatic mode, the tray 50 may be moved to a height corresponding to the food to be cooked at the reference position.

That is, when the cooking of the previous food is completed, the tray 50 may be moved to a reference position and moved to a height corresponding to the new food when cooking the new food. Here, the reference position may be, for example, a position where the height of the support 130 is the same as the rotation shafts 122 and 126 of the rotation members 120 and 125 with respect to the bottom surface of the cavity 20. In this case, the driving time of the driving motors 110 and 112 may be as long as a reference time corresponding to each food.

Alternatively, the tray 50 may be moved from the height at the time of cooking of the previous food to the height corresponding to the new food. In this case, the driving time of the driving motors 110 and 112 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, under the automatic mode, the driving motor is configured to be driven by a timer corresponding to each food, but alternatively, the driving motor may be configured to be rotated by the number of revolutions corresponding to each cooking.

On the other hand, when the manual mode is selected, the drive motor may be operated for a time corresponding to the pressing time of the height adjustment button 48.

Alternatively, the drive motor may be operated for a time corresponding to the number of times the height adjustment button 48 is pressed. That is, the height of the tray 50 is configured to be made in stages, wherein each stage is adjusted as the number of times the height adjustment button 48 is pressed, and the driving time of the driving motor may be determined for each stage.

4 is a view showing a first state in which the position of the tray is adjusted.

Figure 4 shows the position of the tray when cooking food by the radiant heating method.

Referring to FIG. 4, when the food is cooked by the radiant heating method, the heater 26 is operated. When the heater 26 is operated, heat (A) is radiated to the food to heat the food.

Thus, when cooking the food by the radiant heating method, it is preferable that the heater 26 and the food are located close to each other. And, when the food is located close to the heater 26 it is possible to quickly heat the food.

When cooking food by a radiant heating method, as shown in FIG. 4, the driving motors 110 and 160 are rotated in a direction in which the support parts 130 and 140 are raised.

Then, each of the rotating members 120 and 170 rotates in the same direction as the driving motors 110 and 160, and the height of the supporting parts 130 and 140 is increased by the rotation of the rotating members 120 and 170. The food is brought closer to the heater 26.

In this case, as shown in FIG. 4, each of the support parts 130 and 140 is positioned at the same height with respect to the bottom surface 25 of the cavity 20. That is, in the present embodiment, each of the support parts 130 and 140 is rotated in the same direction while maintaining the same height from the bottom surface 25.

Here, as shown in FIG. 4, the support part is positioned higher than the rotation shafts of the rotation members 120 and 170 in the first position in which the support parts 130 and 140 are rotated.

5 is a view showing a second state in which the position of the tray is adjusted.

Referring to FIG. 5, when cooking food by microwave B, the magnetron 27 is operated. As described above, when cooking a food using microwaves, the food is required to be positioned at a height at which microwaves are evenly irradiated with the food. Hereinafter, it will be described with an example that the support 130, 140 is moved to the lower side.

When cooking food using the microwave B, the driving motors 110 and 160 are rotated in a direction in which the supporting parts 130 and 140 descend as shown in FIG. 5. In this case, the driving motors 110 and 160 may be rotated in the same direction as the rotation direction of FIG. 4 or rotated in the opposite direction.

Then, each of the rotating members 120 and 170 is rotated in the same direction as the driving motors 110 and 160, and the height of the supporting parts 130 and 140 is increased by the rotation of the respective rotating members 120 and 170. The food is lowered away from the minnetron 27.

Here, as shown in FIG. 5, in the second position in which the support parts 130 and 140 are rotated, the support parts 130 and 140 are positioned lower than the rotation shafts of the rotation members 120 and 170.

Hereinafter, the operation mode of the vertical movement device will be described.

The user places food on the supports 130 and 140 or puts the tray 50 on which the food is placed on the supports 130 and 140.

Then, the cooking button 44 corresponding to the food is pressed to select a menu to be cooked. Then, the height adjustment mode of the tray 50 is selected by using the mode selection button 46.

If the automatic mode is selected, the tray 50 is moved to a position corresponding to the food.

On the other hand, when the manual mode is selected, the user directly adjusts the height of the tray 50 by using the height adjustment button 48.

Then, after the tray 50 is moved to the required position, the start button 45 is pressed. Then, the heater 26 or the magnetron 27 is operated to cook the food.

According to this embodiment as described above, since the height of the support for supporting the tray on which the food or food is placed can be automatically adjusted by the vertical movement device, there is an effect that the user's convenience is increased.

In addition, since the operation of the vertical movement device can be automatically or manually operated, there is an effect that can selectively adjust the height of the support according to the user's preference.

In addition, since the height of the support may be adjusted according to the type of food, the phenomenon such as cooking less cooked or burned is prevented, so that the optimum cooking of the food is possible.
