In detail, on both side walls of the cavity, a plurality of support portions for supporting the tray are formed. Therefore, the user can selectively adjust the installation position of the tray by placing the tray on any one of the supports.

However, according to the conventional cooking apparatus, since the height of the tray must be directly adjusted by the user, the user is troublesome.

In addition, when the user cooks the food in a state in which the position of the tray is not changed, there is a problem that proper cooking of the food is not performed.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a cooking apparatus which automatically adjusts the height of a tray on which a food is placed or a support for supporting the food.

Another object of the present invention is to provide a cooking apparatus which can automatically adjust the position of a support portion corresponding to a kind of a food.

Another object of the present invention is to provide a cooking apparatus capable of effectively cooking food.

According to an aspect of the invention, there is provided a cooking apparatus comprising: a cavity in which a cooking cavity is formed; A first support portion provided in the cooking chamber to support a tray on which the food or the food is placed and a second support portion disposed parallel to the first support portion and spaced apart from the first support portion, A supporting part which moves up and down while being rotated in the same direction; And a vertical movement device coupled to the support part to move the support part up and down. The up-and-down movement device includes a pair of first rotary members coupled to both sides of the first support part, A first driving motor for rotating the first rotating member, and a second driving motor for rotating the second rotating member.

According to another aspect of the present invention, there is provided a cooking apparatus comprising: a cavity in which a cooking cavity is formed; A first support portion and a second support portion which are provided in the cooking chamber and support the tray on which the food or the food is placed and are spaced apart from each other by a predetermined distance; And a vertical movement device for vertically moving the first support part and the second support part; Wherein the up-and-down moving device includes a pair of rotating members coupled to both sides of the first supporting portion to move the first supporting portion up and down, and a first driving motor for rotating the pair of rotating members, A first up-and-down moving device; A second up-and-down moving device having a pair of rotating members coupled to both sides of the second supporting portion to move the second supporting portion up and down, and a second driving motor for rotating the pair of rotating members; .

According to another aspect of the present invention, there is provided a cooking apparatus comprising: a cavity in which a cooking cavity is formed; First and second supporting portions provided in the cooking chamber and supporting the tray on which the food or the food is placed and spaced apart from each other by a predetermined distance; And a vertical moving device for vertically moving the first and second supporting portions. The up-and-down moving device includes a first vertical moving device for simultaneously moving one side of the first and second supporting portions up and down, 1 and a second up-and-down moving device for simultaneously moving the other side of the second support portion up and down.

According to the proposed embodiment, the height of the supporting portion for supporting the tray on which the food or the food is placed can be automatically adjusted by the up-and-down moving device, thereby improving convenience for the user.

Further, since the operation of the up-and-down moving device can be automatically or manually operated, the height of the support portion can be selectively adjusted according to the user's taste.

In addition, since the height of the support portion can be adjusted corresponding to the type of the food, there is an advantage that the phenomenon such as less cooking or less burning of the food is prevented, and optimum cooking of the food is possible.

Hereinafter, embodiments will be described in detail with reference to the drawings.

1 is a perspective view of a door of a cooking device according to a first embodiment of the present invention.

Referring to FIG. 1, the cooking apparatus 1 according to the present embodiment includes an outer case 10 forming an outer shape, a cavity 20 provided inside the outer case 10 and forming a cooking chamber 21, A tray 50 installed in the cavity 20 for placing the food therein, a heating source for heating the food placed on the tray 50, A door 30 for selectively opening and closing the cooking chamber 21 and a vertical movement device for moving the tray 50 upward and downward.

In detail, the cavity 20 is formed in a substantially rectangular parallelepiped shape, and the front portion is opened, and the opened portion is selectively shielded by the door 30.

The tray 50 is supported by the up-and-down moving device. That is, unlike the prior art, the present embodiment is not provided with support portions for supporting the tray 50 on both side walls of the cavity 20. Therefore, the structure of the cavity 20 is simplified, and the inner surface is cleaned.

The heating source includes a heater 26 provided on the upper side of the cavity 20 and a magnetron 27 (see FIG. 2) provided on the outer side of the cavity 20 to oscillate microwaves.

On the other hand, the control panel 40 allows a user to operate the operation of the cooking appliance 1. [ The control panel 40 may include at least a power button 42, a cooking button 44, and a start button 45.

In addition, a mode selection button 46 for selecting an operation mode of the up-and-down moving device and a height adjustment button 48 for allowing the tray 50 to be moved up and down to a desired height can be further included.

The up-and-down moving device rotates in a state supporting the tray 50 to move the tray 50 up and down.

2 is a perspective view showing a state in which the up-and-down moving device according to the first embodiment is installed.

Referring to FIG. 2, a pair of up-and-down moving devices 100 and 150 of the cavity 20 are provided. The pair of up-and-down moving devices 100 and 150 includes a first up-and-down moving device 100 and a second up-down moving device 150.

The upper and lower moving devices 100 and 150 are coupled to the first and second supporting portions 130 and 140 for supporting the tray 50 on which the food or the food is placed.

The vertical movement devices 100 and 150 are spaced apart from each other by a predetermined distance from the side of the cavity 20.

The supports 130 and 140 are provided in the same number as the up-and-down moving devices 100 and 150 and are spaced apart from each other by a predetermined distance.

In this embodiment, the support portions 130 and 140 are elongated in the left-right direction, and the plurality of support portions 130 and 140 are spaced apart from each other in the front-rear direction. The plurality of supports 130 and 140 are arranged in parallel.

The first vertical movement device 100 includes a pair of first driving motors 110 and 112 provided outside the cavity 20 to generate a driving force, And a pair of first rotating members 120 and 125 rotated by the first rotating member.

The first support portion 130 is coupled to the pair of first rotary members 120 and 125.

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

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

In this embodiment, since the pair of up-and-down moving devices have the same structure and different installation positions, only the first up-and-down moving device will be described below.

The drive motors 110 and 112 include a left drive motor 110 provided outside the first side wall 23 (left side wall in FIG. 2) of the cavity 20, And a right drive motor 112 provided outside the two side walls 24 (right side wall in Fig. 2).

A bidirectional motor may be used as the drive motors 110 and 112 so that both directions of the pair of rotary members 120 and 125 are rotatable. For example, a stepping motor may be used.

The pair of rotating members 120 and 125 include a left rotating member 120 and a right rotating member 125. [ The left and right rotatable members 120 and 125 are positioned inside the cavity 20. The rotation axis 122 of the left rotation member 120 is connected to the axis of the left driving motor 110 through the left side wall 23 of the cavity 20.

The rotation shaft 126 of the right rotation member 125 penetrates the right side wall 24 of the cavity 20 and is connected to the shaft of the right drive motor 112.

A gear is formed on the shafts 122 and 126 of the rotary members 120 and 125 and a gear is connected to the shafts of the drive motors 110 and 112 so that the drive motors 110 and 112 May be transmitted to each of the rotary members 120 and 125.

The rotation members 120 and 125 are formed to have a length larger than the width. The rotation members 120 and 125 are formed with coupling holes 124 and 128 for coupling the supporting portion 130. The support portion 130 is supported by the rotary members 120 and 125 in a state of being coupled to the rotary 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 rotary members 120 and 125 by a predetermined distance. At this time, 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.

Accordingly, when the driving motors 110 and 112 are rotated, the rotating members 120 and 125 connected to the driving motors 110 and 112 are rotated. When the rotating members 120 and 125 are rotated, the supporting unit 130 rotates around the rotating shafts 122 and 126 of the rotating members 120 and 125.

Since the support portion 130 is spaced apart from the rotation shafts 122 and 126 of the rotary members 120 and 125, when the support portion 130 is rotated, the bottom surface 25 of the cavity 20 And the height changes.

Here, when viewing the rotation direction of the support portion with respect to the drive motor, the support portion is rotated in one direction with respect to the left drive motor, and is rotated in the other direction with respect to the right drive motor. That is, each of the drive motors is rotated in the opposite direction. On the other hand, when the direction in which the other side is viewed from one side of the cavity is referred to, the respective driving motors are rotated in the same direction.

Therefore, in the present embodiment, it is assumed that each of the drive motors is operated such that the support portion 130 rotates in one direction.

3 is a block diagram showing a control configuration of the cooking apparatus according to the first embodiment.

3, the cooking apparatus according to the present embodiment includes an input unit 210 for a user to input an operating condition of the cooking apparatus, and a controller 210 for enabling the tray 50 to be moved up and down And a control unit 220 for controlling the driving unit 230. The control unit 220 controls the driving unit 230,

In detail, the input unit 210 includes at least a cooking button 44 for cooking food, a mode selection button 46 for selecting a height adjustment mode of the tray 50, And a height adjustment button 48 for allowing the user to directly manipulate the height of the display screen.

Therefore, the height of the tray 50 can be adjusted automatically or manually by a user's operation according to the selected mode. When the manual mode is selected, the user can move the tray 50 up and down to a height desired by the user using the height adjustment button 48.

The driving unit 230 includes a driving 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 can be detected by the timer.

In the automatic mode, the tray 50 can 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 is moved to the reference position and can be moved to the height corresponding to the new food when the new food is cooked. Here, the reference position may be a position where the height of the supporter 130 is the same as the rotation axes 122 and 126 of the rotatable 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 will be equal to the reference time corresponding to each food.

Alternatively, the tray 50 can be moved from the height of the previous cooking to the height corresponding to the new food. In this case, the driving time of the driving motors 110 and 112 will be equal to the difference between the reference time corresponding to the previous food and the reference time corresponding to the new food.

In the present embodiment, the drive motor is configured to be driven by a timer for a time corresponding to each food under the automatic mode. Alternatively, the drive motor may be configured to be rotated by the number of revolutions corresponding to each preparation.

On the other hand, when the manual mode is selected, the driving motor can be operated for a time corresponding to the pressing time of the height adjusting button 48. [

Alternatively, the driving motor may be operated for a time corresponding to the number of presses of the height adjustment button 48. [ That is, the height of the tray 50 is configured to be stepwise, and each step is adjusted according to the number of presses of the height adjusting button 48, and the driving time of the driving motor can be determined for each step.

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

Fig. 4 shows the position of the tray when the food is cooked by the radiant heating method.

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

When the food is cooked by the radiant heating method as described above, it is preferable that the heater 26 and the food are located close to each other. When the food is located close to the heater 26, rapid heating of the food is possible.

When the cooked food is cooked by the radiant heating method, the driving motors 110 and 160 are rotated in the direction in which the supporting portions 130 and 140 are lifted as shown in FIG.

The rotatable members 120 and 170 are rotated in the same direction as the driving motors 110 and 160 and the rotation of the rotatable members 120 and 170 increases the height of the supports 130 and 140 So that the food is brought close to the heater 26.

At this time, as shown in FIG. 4, the supports 130 and 140 are positioned at the same height with respect to the bottom surface 25 of the cavity 20. That is, in the present embodiment, the support portions 130 and 140 are rotated in the same direction while maintaining the same height from the bottom surface 25.

Here, as shown in FIG. 4, at the first position where the support portions 130 and 140 are rotated, the support portion is located higher than the rotation axis of the rotation members 120 and 170. [

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

Fig. 5 shows the position of the tray when the food is cooked by the microwave.

Referring to FIG. 5, when cooked food is cooked by the microwave B, the magnetron 27 is operated. When the cooked food is cooked using the microwave, the cooked food is required to be positioned at a height for the microwave to be uniformly irradiated with the cooked food. Hereinafter, the support portions 130 and 140 are moved downward.

When the cooked food is cooked using the microwave (B), the driving motors (110, 160) are rotated in a direction in which the supporting portions (130, 140) descend as shown in FIG. At this time, the drive motors 110 and 160 may be rotated in the same direction as the rotation direction of FIG. 4 or may be rotated in the opposite direction.

The rotating members 120 and 170 are rotated in the same direction as the driving motors 110 and 160 and the rotation of the rotating members 120 and 170 causes the height of the supporting members 130 and 140 So that the cooking water is moved away from the Mynetron 27.

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

Hereinafter, the operation mode of the up-and-down moving device will be described.

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

Then, a menu to be cooked is selected by pressing the cooking button 44 corresponding to the cooking. Then, the height adjustment mode of the tray 50 is selected 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, if the manual mode is selected, the user directly adjusts the height of the tray 50 using the height adjustment button 48. [

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

According to the present embodiment as described above, the height of the support portion for supporting the tray on which the food or the food is placed can be automatically adjusted by the up-and-down moving device, thereby enhancing convenience for the user.

Further, since the operation of the up-and-down moving device can be automatically or manually operated, the height of the support portion can be selectively adjusted according to the user's taste.

In addition, since the height of the support portion can be adjusted corresponding to the type of the food, there is an advantage that the phenomenon such as less cooking or less burning of the food is prevented, and optimum cooking of the food is possible.

6 is a perspective view showing a state in which the up-and-down moving device according to the second embodiment is installed.

The present embodiment is the same as the first embodiment in other parts, except that the pair of rotating members are simultaneously rotated by one driving motor. Therefore, only the characteristic parts of the present embodiment will be described below.

6, the up-and-down moving device according to the present embodiment includes a first vertical moving device 300 provided on the left side of the cavity 20 and a second vertical moving device 300 provided on the right side of the cavity 20, Apparatus 400 is included.

Each of the up-and-down moving devices 300 and 400 includes one driving motor 310 and 410, a power transmitting part 320 and 420 coupled to a shaft of the driving motor 310 and 410 to transmit power, And a rotating unit rotated by the power transmission units 320 and 420.

The rotary unit includes a first rotary member 330 and 430 positioned adjacent to the rear wall of the cavity 20 and a second rotary member 340 and 440 positioned adjacent to the opening of the cavity 20, .

Therefore, in the present embodiment, a pair of first rotating members 330 and 430 and a pair of second rotating members 340 and 440 are provided.

In detail, the power transmission parts 320 and 420 may be gears, for example. The rotary shafts 332, 342, 432 and 442 of the rotary members 330, 340, 430 and 440 pass through the side walls 23 and 24 of the cavity 20, respectively. Gears 334, 344, 434, and 444 for engaging with the power transmission units 320 and 420 are formed on the respective rotation shafts 332, 342, 432, and 442.

The first supporting member 130 is coupled to the pair of first rotating members 330 and 430 and the second supporting member 140 is coupled to the pair of second rotating members 340 and 440.

Accordingly, when the drive motors 310 and 410 rotate, the power transmission parts 320 and 420 coupled with the axes of the drive motors 310 and 410 are rotated. When the power transmission units 320 and 420 are rotated, the pair of rotation members 330, 340, 430, and 440 engaged with the power transmission units 320 and 420 are rotated in one direction. As the pair of rotating members 330, 340, 430, and 440 are rotated, the supporting portions 130 and 140 coupled to the rotating members 330, 340, 430, and 440 are rotated and the height thereof is adjusted .

According to the present embodiment as described above, since a plurality of rotating members can be rotated by one driving motor, the cost is reduced.
