[0130] FIG. 9 illustrates the operation of a plurality of covers of a cooking appliance according to one embodiment.

[0131] The first cover (101) can move between a first position (P1) covering the suction port (12) and a second position (P2) opening the suction port (12).

[0132] The second cover (102) can move between a third position (P3) covering the suction port (12) and a fourth position (P4) opening the suction port (12).

[0133] The suction port (12) can be fully covered depending on the positions of the first cover (101) and the second cover (102). For example, the suction port (12) can be fully covered when the first cover (101) moves to the first position (P1) and the second cover (102) moves to the third position (P3).

[0134] The suction port (12) may be partially opened depending on the positions of the first cover (101) and the second cover (102). For example, the suction port (12) may be partially opened when the first cover (101) moves to the second position (P2) and the second cover (102) moves to the third position (P3), or when the first cover (101) moves to the first position (P1) and the second cover (102) moves to the fourth position (P4).

[0135] The suction port (12) can be fully opened depending on the positions of the first cover (101) and the second cover (102). For example, the suction port (12) can be fully opened when the first cover (101) moves to the second position (P2) and the second cover (102) moves to the fourth position (P4).

[0136] In one embodiment, the control unit (110) can control the driving device (200) to move the first cover (101) between a first position (P1) and a second position (P2).

[0137] For example, the control unit (110) can control the driving device (200) to move the first cover (101) from the first position (P1) to the second position (P2). As another example, the control unit (110) can control the driving device (200) to move the first cover (101) from the second position (P2) to the first position (P1).

[0138] In one embodiment, the control unit (110) can control the drive unit (200) to move the second cover (102) between a third position (P3) and a fourth position (P4).

[0139] For example, the control unit (110) can control the driving device (200) to move the second cover (102) from the third position (P3) to the fourth position (P4). As another example, the control unit (110) can control the driving device (200) to move the second cover (102) from the fourth position (P4) to the third position (P3).

[0140] In one embodiment, the control unit (110) can control the driving device (200) to move the first cover (101) and the second cover (102) simultaneously.

[0141] For example, the control unit (110) can control the driving device (200) so that the first cover (101) at the first position (P1) moves to the second position (P2) and at the same time the second cover (102) at the third position (P3) moves to the fourth position (P4).

[0142] As another example, the control unit (110) can control the driving device (200) to move the first cover (101) at the second position (P2) to the first position (P1) and at the same time move the second cover (102) at the fourth position (P4) to the third position (P3).

[0143] In one embodiment, the control unit (110) can control the driving device (200) to sequentially move the first cover (101) and the second cover (102).

[0144] For example, the control unit (110) can control the driving device (200) to move the first cover (101) at the first position (P1) to the second position (P2), and then control the driving device (200) to move the second cover (102) at the third position (P3) to the fourth position (P4).

[0145] For another example, the control unit (110) may control the driving device (200) to move the second cover (102) at the third position (P3) to the fourth position (P4), and then control the driving device (200) to move the first cover (101) at the first position (P1) to the second position (P2).

[0146] For another example, the control unit (110) may control the driving device (200) to move the first cover (101) at the second position (P2) to the first position (P1), and then control the driving device (200) to move the second cover (102) at the fourth position (P4) to the third position (P3).

[0147] For another example, the control unit (110) may control the driving device (200) to move the second cover (102) at the fourth position (P4) to the third position (P3), and then control the driving device (200) to move the first cover (101) at the second position (P2) to the first position (P4).

[0148] Figures 10, 11 and 12 illustrate the operation of multiple covers when a cooking vessel is placed in a cooking area according to one embodiment.

[0149] The cooking device (1) can control the driving device (200) to move the first cover (101) of the first position (P1) to the second position (P2) based on the cooking container being placed in the first cooking area (ca1).

[0150] For example, referring to FIG. 10, the control unit (110) can control the driving device (200) to move the first cover (101) at the first position (P1) to the second position (P2) based on the fact that a cooking vessel is placed in the first cooking area (ca1) and no cooking vessel is placed in the second cooking area (ca2). In this case, a portion of the suction port (12) can be opened.

[0151] The cooking device (1) can control the driving device (200) to move the second cover (102) of the third position (P3) to the fourth position (P2) based on the cooking container being placed in the second cooking area (ca2).

[0152] For example, referring to FIG. 11, the control unit (110) may control the driving device (200) to move the second cover (102) at the third position (P3) to the fourth position (P4) based on the fact that a cooking vessel is placed in the second cooking area (ca2) and no cooking vessel is placed in the first cooking area (ca1). In this case, the suction port (12) may be partially opened.

[0153] Referring to FIG. 12, in one embodiment, the control unit (110) can control the driving device (200) to move the first cover (101) at the first position (P1) to the second position (P2) and the second cover (102) at the third position (P3) to the fourth position (P4) based on the cooking containers being placed in the first cooking area (ca1) and the second cooking area (ca2). In this case, the suction port (12) can be fully opened.

[0154] However, the control unit (110) according to the present disclosure is not limited to controlling the driving device (200) to move the first cover (101) and the second cover (102).

[0155] The control unit (110) can control the driving device (200) to move some of the covers (100) among the plurality of covers (100) based on a user input received through the input interface device (14b) even if no cooking container is placed in the cooking area (ca).

[0156] For example, the control unit (110) can control the driving device (200) to move the first cover (101) between the first position (P1) and the second position (P2) through an input signal received from the input interface device (14b).

[0157] As another example, the control unit (110) can control the driving device (200) to move the second cover (102) between the third position (P3) and the fourth position (P4) through an input signal received from the input interface device (14b).

[0158] FIG. 13 is a flowchart illustrating the operation of multiple covers and fans of a cooking appliance based on the level of contamination detected by a gas sensor when a cooking vessel is placed in a cooking area according to one embodiment. FIG. 14 illustrates the operation of multiple covers based on the level of contamination detected by a gas sensor when a cooking vessel is placed in a cooking area according to one embodiment.

[0159] As described above, the cooking appliance (1) can control the driving device (200) to move the first cover (101) of the first position (P1) to the second position (P2) based on the cooking vessel being placed in the first cooking area (ca1) (1000)

[0160] The cooking device (1) can control the rotation speed of the fan (51) to a first rotation speed based on the placement of the cooking vessel in the first cooking area (ca1) (1010). The first rotation speed may be a rotation speed of the fan (51) that can sufficiently suck in air on the cooking plate (11) when the first cover (101) is in the second position (P2) and the second cover (102) is in the third position (P3).

[0161] Referring to FIGS. 13 and 14, the cooking appliance (1) can control the driving device (200) to move the second cover (102) to the fourth position (P4) (1040) based on the contamination level detected by the gas sensor (90) exceeding the reference contamination level (Yes of 1030) even if no cooking vessel is placed in the second cooking area (ca2) (No of 1020). In this case, the suction port (12) can be fully opened.

[0162] The cooking appliance (1) can control the rotation speed of the fan (51) to a second rotation speed based on the contamination level detected by the gas sensor (90) exceeding the standard contamination level (example of 1030). The second rotation speed may be greater than the first rotation speed. The second rotation speed may be a rotation speed of the fan (51) that can sufficiently suck in air on the cooking plate (11) when the first cover (101) is in the second position (P2) and the second cover (102) is in the fourth position (P4).

[0163] In one embodiment, the control unit (110) can control the driving device (200) to move the second cover (102) at the fourth position (P4) to the third position (P3) when the cooking vessel is not placed in the second cooking area (ca2) and the contamination level detected by the gas sensor (90) falls below the reference contamination level.

[0164] For example, when a cooking vessel is placed in the first cooking area (ca1), the first cover (101) is in the second position (P1), and the second cover (102) is in the fourth position (P4), the control unit (110) can control the driving device (200) to move the second cover (102) in the fourth position (P4) to the third position (P3) based on the fact that the cooking vessel is not placed in the second cooking area (ca2) and the contamination level detected by the gas sensor (90) is less than the reference contamination level.

[0165] In one embodiment, the control unit (110) can control the rotation speed of the fan (51) to the first rotation speed when no cooking vessel is placed in the second cooking area (ca2) and the contamination level detected by the gas sensor (90) falls below the standard contamination level.

[0166] For example, when a cooking vessel is placed in the first cooking area (ca1), the first cover (101) is in the second position (P1), and the second cover (102) is in the fourth position (P4), the control unit (110) can control the rotation speed of the fan (51) to a first rotation speed lower than the second rotation speed based on the fact that the cooking vessel is not placed in the second cooking area (ca2) and the contamination level detected by the gas sensor (90) is lower than the reference contamination level.

[0167] The amount of air on the cooking plate that must be sucked in during the cooking process in some of the multiple cooking areas may be relatively less than the amount of air on the cooking plate that must be sucked in during the cooking process in all cooking areas.

[0168] Therefore, in terms of energy consumption, it is necessary to operate the fan at a relatively lower rotation speed in some cooking areas among multiple cooking areas during cooking operations than in all cooking areas during cooking operations.

[0169] However, in some cooking areas, when the fan (51) operates at a relatively low rotation speed during the cooking process, if the intake ports are fully opened, the air flow velocity is low and the air on the cooking plate cannot be sufficiently sucked in.

[0170] According to the present disclosure, it is possible to individually move a plurality of covers according to the cooking area where the cooking container is placed and control the rotation speed of the fan to reduce unnecessary energy consumption.

[0171] According to the present disclosure, a plurality of covers can be moved based on the level of contamination detected by a gas sensor, and the rotation speed of the fan can be adjusted to efficiently absorb contaminants generated during a cooking process.

[0174] The duct (40) may include a first duct (40a) and a second duct (40b). The first duct (40a) and the second duct (40b) may receive air discharged from the chamber housing (30). The first duct (40a) and the second duct (40b) may guide the air discharged from the chamber housing (30) to the outside or to a space where the cooking device (1) is installed. For example, the first duct (40a) may be connected to a first outlet (35a) of the chamber housing (30), and the second duct (40b) may be connected to a second outlet (35b) of the chamber housing (30). For example, the other ends of the first duct (40a) and the second duct (40b) may be connected to the outdoors or indoors.

Although the drawing illustrates that the first fan device (50a) and the second fan device (50b) are housed in the chamber housing (30), the present disclosure is not limited thereto. For example, the first fan device (50a) may be housed in the first duct (40a), and the second fan device (50b) may be housed in the second duct (40b).

[0178] The first fan device (50a) may include a first fan (51a).
