Description

Exhaust device, cooking appliance having an exhaust device, and method for controlling a cooking appliance

[0001] The disclosed invention relates to an exhaust device that inhales contaminated air generated during the cooking of food through another cooking device and discharges the inhaled contaminated air to the outside, a cooking device having an exhaust device, and a method for controlling the cooking device.

[0002] Cooking appliances are devices that heat food for cooking, and they are broadly classified into methods that generate heat using electricity and methods that generate heat by burning gas. For example, cooking appliances can be categorized into gas ranges, ovens, induction heaters, halogen heaters, and microwave ovens.

[0003] Cooking appliances generate smoke and odors during food preparation. For this reason, the room is equipped with an exhaust system to expel the smoke and odors generated during cooking to the outside.

[0004] Recently, an over-the-range (OTR) equipped with an exhaust system has been installed on the wall of the upper space within a room, and other cooking appliances (e.g., gas range, oven, induction heater, halogen heater, etc.) have been installed below the OTR on the floor of the room, thereby enabling the use of multiple cooking appliances within a specific area of ​​the room.

[0005] In this case, the exhaust device provided in the microwave oven sucked in smoke or odors generated from another cooking appliance located at the bottom of the microwave oven from the top of the other cooking appliance and discharged the sucked smoke or odors to the outside.

[0006] Conventional exhaust systems are effective at drawing in smoke and odors rising vertically from the horizontal plane where the system is installed toward the upper part of the room. However, they had a problem in that they could not draw in smoke or odors originating from areas outside the horizontal plane covered by the microwave that move from the front toward the center of the room, or smoke or odors rising vertically from the lower area not covered by the microwave. As a result, conventional exhaust systems suffered from low intake and exhaust performance.

[0007] One aspect of the disclosed invention provides an exhaust device that controls the tilting rotation of a second suction part to suck in air contaminated by cooking food from the front and bottom and discharge the sucked contaminated air to the outside, a cooking device having an exhaust device, and a method for controlling the cooking device.

[0200] The second edge (141b) of the first guide panel (141) may be a part that moves when the second suction part (140) is tilted and rotated. The moving position of the second edge (141b) of the first guide panel (141) may change depending on the tilting angle of the second suction part (140).

[0201] The third edge (141c) of the first guide panel (141) may be adjacent to the first side of the main body (200) of the first cooking device (2).

[0202] The fourth edge (141d) of the first guide panel (141) may be adjacent to the second side of the main body (200) of the first cooking device (2).

[0203] The third edge (141c) and the fourth edge (141d) of the first guide panel (141) can be parts that move when the second suction part (140) is tilted and rotated.

[0204] The third edge (141c) and the fourth edge (141d) of the first guide panel (141) may have different moving positions depending on the tilting angle of the second suction part (140).

[0205] The second guide panel (142) can be provided on the third edge (141c) of the first guide panel (141).

[0206] The second guide panel (142) can be adjacent to the first side of the main body (200) and can be adjacent to the first side of the door (220).

[0207] The second guide panel (142) can be formed in a triangular shape.

[0208] The second guide panel (142) may be a part that moves when the second suction part (140) is tilted and rotated. The size of the surface of the second guide panel (142) exposed to the outside of the main body (200) may vary depending on the tilting angle of the second suction part (140).

[0209] The third guide panel (143) can be provided on the fourth edge (141d) of the first guide panel (141).

[0210] The third guide panel (143) can be adjacent to the second side of the main body (200) and to the third side of the door (220).

[0211] The third guide panel (143) may be formed in a triangular shape. The third guide panel (143) may face the second guide panel (142).

[0212] The third guide panel (143) may be a part that moves when the second suction part (140) is tilted and rotated. The size of the surface of the third guide panel (143) exposed to the outside of the main body may vary depending on the tilting angle of the second suction part (140).

[0213] As shown in FIG. 9, the first, second, and third guide panels (141, 142, 143) can be drawn out from the first panel (201) by being exposed to the outside of the main body (200) by the tilting rotation of the second suction part (140).

[0214] The first, second, and third guide panels (141, 142, 143) can form an opening, i.e., a suction port (145), based on being exposed to the outside of the main body (200) by the tilting rotation of the second suction part (140).

[0215] The first, second, and third guide panels (141, 142, 143) can be configured to adjust the size of the suction port (145) based on the control of the tilting angle of the second suction part (140).

[0216] The first, second, and third guide panels (141, 142, 143) can guide the flow of contaminated air so that contaminated air present at the front of the main body (200), i.e., around the door (220), can be sucked into the intake port (145).

[0217] The amount of contaminated air sucked into the second suction part (140) can be controlled based on the size adjustment of the suction port (145) of the first, second, and third guide panels (141, 142, 143).

[0218] The first cooking device (2) may further include a duct connected to the second suction part (140) and a damper provided inside the duct.

[0219] In the case where a duct and a damper are provided in the first cooking device, for example, the first cooking device (2) can control the opening of the suction port of the second suction part (140), and it is also possible to control the damper to open based on the second suction part (140) being exposed to the outside of the main body, and to control the damper to close based on the second suction part (140) being received into the inside of the main body.

[0220] In the case where a duct and a damper are provided in the first cooking device, as another example, the first cooking device (2) may control the tilting rotation of the first suction part so that the opening of the suction port of the second suction part (140) reaches a preset opening based on the second suction part (140) being exposed to the outside of the main body, control the opening of the damper based on the degree of contamination, and control the closing of the damper based on the second suction part (140) being received into the interior of the main body.

[0221] In another example, when a duct and a damper are provided in the first cooking device, the first cooking device (2) controls the tilting rotation of the second suction part (140) based on the second suction part (140) being exposed to the outside of the main body, and it is also possible to control the opening of the suction port and the opening of the damper based on the degree of contamination.

[0222] The second suction part (140) may further include a lighting hole (144).

[0223] A lighting unit (160) for indicating whether an exhaust operation is performed may be provided in the lighting hole (144). The lighting unit (160) may be lit based on whether an exhaust operation is performed and turned off based on whether an exhaust operation is not performed.

[0224] The lighting unit (160) can be fixedly mounted to the second suction unit (140). The lighting unit (160) can also be detachably provided in the lighting hole (144).

[0225] As illustrated in FIG. 10, the driving assembly (150) may be provided in the central area of ​​the first panel (201). The driving assembly (150) may be provided between the first suction panel (131) and the second suction panel (132).

[0226] The driving assembly (150) can apply force to the lighting unit (160) fixed to the second suction unit (140) to enable tilting rotation of the second suction unit (140).

[0227] More specifically, when the driving assembly (150) applies force to the lighting unit (160), the force applied to the lighting unit (160) can be transmitted to the first guide panel (141) of the second suction unit (140). Then, due to the force transmitted to the first guide panel (141) of the second suction unit (140), the second edge moves with the first edge as an axis, and the second and third guide panels (142, 143) fixed to the first guide panel (141) also move together. As a result, the second and third guide panels (142, 143) of the second suction unit can be exposed to the outside of the main body (200), and a suction port can be formed by the exposure of the second and third guide panels (142, 143).

[0228] As illustrated in FIG. 11, the drive assembly (150) may include a drive motor (151), a first gear (152), a second gear (153), a connecting rod (154), and a push member (155).

[0229] The drive motor (151) can generate rotational force for driving.

[0230] The drive motor (151) may rotate in a first rotation direction or in a second rotation direction. The first rotation direction may be opposite to the second rotation direction. For example, if the first rotation direction is clockwise, the second rotation direction may be counterclockwise. For another example, if the first rotation direction is counterclockwise, the second rotation direction may be clockwise.

[0231] The first gear (152) is connected to the shaft of the drive motor (151) and can rotate in conjunction with the rotation of the drive motor (151). The first gear (152) can rotate in the first rotational direction as the drive motor (151) rotates in the first rotational direction, and can rotate in the second rotational direction as the drive motor (151) rotates in the second rotational direction.

[0232] The first gear (152) may be a pinion gear with a circular shape and a first tooth formed on its outer surface.

[0233] The second gear (153) can be connected to the first gear (152).

[0234] The second gear (153) may be a rack gear that has a straight shape and has a second tooth formed on at least one surface.

[0235] The second tooth of the second gear (153) may be engaged with the first tooth of the first gear (152). As a result, the second gear (153) can receive power from the rotation of the first gear (152).

[0236] The second gear (153) can perform translational motion by the rotational force of the first gear (152).

[0237] The second gear (153) can move straight in the first direction by the first gear (152) rotating in the first rotational direction, and can move straight in the second direction by the first gear (152) rotating in the second rotational direction.

[0238] In this embodiment, the first rotation direction may be counterclockwise. The second rotation direction may be clockwise.

[0239] Straight movement in the first direction may include moving from the rear to the front of the first cooking device.

[0240] The straight movement in the second direction may include moving downward from the front of the first cooking device.

[0241] The drive assembly (150) includes first and second gears that convert the rotational motion of the drive motor (151) into linear motion, but the components for converting the rotational motion of the drive motor into linear motion are not limited to this.

[0242] For example, the drive assembly (150) may include a cam that converts the rotational motion of the drive motor (151) into linear motion.

[0243] The connecting rod (154) can be connected to the second gear (153).

[0244] The connecting rod (154) can be connected to the end of the second gear (153) and fixed.

[0245] The connecting rod (154) can move in conjunction with the movement of the second gear (153).

[0246] When the second gear (153) moves straight in the first direction, the connecting rod (154) can move straight in the first direction by the moving force of the second gear (153).

[0247] When the second gear (153) moves straight in the second direction, the connecting rod (154) can move straight in the second direction by the moving force of the second gear (153).

[0248] The push member (155) can be connected to the connecting rod (154).

[0249] The push member (155) can be connected to the end of the connecting rod (154) and fixed.

[0250] The push member (155) can move in conjunction with the movement of the connecting rod (154).

[0251] The push member (155) can move in a straight line in the first direction by the moving force of the connecting rod (154) when the connecting rod (154) moves in a straight line in the first direction.

[0252] The push member (155) can move in a straight line in the second direction by the moving force of the connecting rod (154) when the connecting rod (154) moves in a straight line in the second direction.

[0253] The push member (155) may be provided to be able to contact the lighting unit (160). The push member (155) may be provided to be able to contact the middle area or the upper area of ​​the body of the lighting unit (160).

[0254] The push member (155) may also be fixed to the lighting unit (160). The push member (155) may also be fixed to the middle area or the upper area of ​​the body of the lighting unit (160).

[0255] The push member (155) can transmit movement force in the first direction to the lighting unit (160) when movement force in the first direction is applied from the connecting rod (154), and can transmit movement force in the second direction to the lighting unit (160) when movement force in the second direction is applied from the connecting rod (154).

[0256] The push member (155) can apply force to the lighting unit (160) in a first direction or apply force to the lighting unit (160) in a second direction.

[0257] When the push member (155) applies a force in the first direction to the lighting unit (160), it can apply force to the middle area or the upper area of ​​the body of the lighting unit (160).

[0258] The push member (155) can also remove the force applied to the lighting unit (160) in the first direction.

[0259] When a force in the first direction is applied from the push member (155), the lighting unit (160) can transmit the applied force in the first direction to the first guide panel (141).

[0260] Since the lighting unit (160) and the first guide panel (141) are fixed to each other, the force in the first direction applied to the lighting unit (160) can be transmitted directly to the first guide panel (141).

[0261] Since the first guide panel (141) has a first edge (141a) fixed, when a force in the first direction is applied, it can move in a direction where there is no restraining force due to the applied force or in a direction where the restraining force is weaker than the applied force.

[0262] Here, the direction without restraint or the direction with less restraint than the applied force may be a direction corresponding to the outside of the main body (200).

[0263] That is, when a force in the first direction is applied to the lighting unit (160) and the first guide panel (141), the second edge can be moved with the first edge (141a) of the first guide panel (141) as the axis.

[0264] As illustrated in FIG. 12a, the drive assembly (150) causes the second gear (153) to move linearly in the first direction by rotating the drive motor (151) and the first gear (152) in the first rotational direction, and causes the connecting rod (154) and the push member (155) to move in the first direction by the linear movement of the second gear (153), and causes force to be applied to the lighting unit (160) by the movement of the connecting rod (154) and the push member (155).

[0341] The control unit (280) can recognize the tilting angle of the second suction unit based on position information received from the position sensor (156).

[0342] Manual Exhaust Mode Control

[0343] When the control unit (280) receives an exhaust on command through the input unit (231), it identifies the exhaust mode received through the input unit (231), identifies the exhaust level received through the input unit (231) based on the fact that the identified exhaust mode is a manual exhaust mode, controls the lighting unit (160) based on the identified exhaust level, controls the rotational speed of the first and second fan motors (112, 122), and controls the tilting rotation of the second suction unit (140).

[0344] The control unit (280) can control the rotation angle of the drive motor (151) when controlling the tilting rotation of the second suction unit.

[0345] The control unit (280) can form a barrier (or air curtain) by the flow of contaminated air in the front direction of the first cooking device by causing the intake port of the second intake unit to protrude outside the main body (200) of the first cooking device through the tilting rotation of the second intake unit.

[0346] More specifically, the control unit (280) can control the first and second fan motors (112, 122) to a first rotational speed based on the fact that the received exhaust level is a first exhaust level, and can control the first and second fan motors (112, 122) to a second rotational speed based on the fact that the received exhaust level is a second exhaust level.

[0347] Here, the second rotational speed may be faster than the first rotational speed. The second exhaust level may be higher than the first exhaust level.

[0348] The control unit (280) can control the closure of the intake port (145) of the second intake unit (140) based on whether the received exhaust level is the first exhaust level or the second exhaust level.

[0349] That is, if the received exhaust level is the first exhaust level or the second exhaust level, the control unit (280) allows the intake port (145) of the second intake unit (140) to be accommodated inside the main body.

[0350] The first rotational speed of the first fan motor (112) and the first rotational speed of the second fan motor (122) may be the same or different. This embodiment describes an example in which the rotational speeds of the first and second fan motors (112, 122) are controlled to be the same based on the exhaust level.

[0351] The control unit (280) can control the first and second fan motors (112, 122) to a second rotational speed based on the fact that the received exhaust level is a third exhaust level, and can control the drive motor (151) so that the intake port (145) of the second intake unit (140) is exposed to the outside of the main body (200).

[0352] That is, the control unit (280) can control the rotation angle of the drive motor (151) so that the tilting angle of the second intake unit (140) reaches a preset tilting angle based on the fact that the received exhaust level is the third exhaust level. Here, the preset tilting angle may be the maximum tilting angle.

[0353] The control unit (280) may control the first and second fan motors (112, 122) to a third rotational speed based on the fact that the received exhaust level is a third exhaust level, and may also control the rotational angle of the drive motor (151) so that the tilting angle of the second suction unit (140) reaches a preset tilting angle. The third rotational speed may be a rotational speed faster than the second rotational speed.

[0354] If there is an exhaust level higher than the third exhaust level, the control unit (280) may also adjust the tilting angle of the second intake unit (140) based on the received exhaust level if the received exhaust level is higher than or equal to a preset exhaust level.

[0355] Here, the preset exhaust level may be the third exhaust level. Exhaust levels greater than or equal to the preset exhaust level may include the third exhaust level, the fourth exhaust level, and the fifth exhaust level. The fourth and fifth exhaust levels are merely examples of the present embodiment, and the number of exhaust levels is not limited thereto.

[0356] More specifically, the control unit (280) can control the rotation angle of the drive motor (151) to a first rotation angle so that the tilting angle of the second suction unit (140) reaches a first tilting angle when the received exhaust level is a third exhaust level, control the rotation angle of the drive motor (151) to a second rotation angle so that the tilting angle of the second suction unit (140) reaches a second tilting angle when the received exhaust level is a fourth exhaust level, and control the rotation angle of the drive motor (151) to a third rotation angle so that the tilting angle of the second suction unit (140) reaches a third tilting angle when the received exhaust level is a fifth exhaust level.

[0357] The third tilting angle may be a larger angle than the second tilting angle. The second tilting angle may be a larger angle than the first tilting angle.

[0358] As the tilting angle increases, the opening of the suction port of the second suction part can increase.

[0359] That is, if the received exhaust level is the third exhaust level, the fourth exhaust level, or the fifth exhaust level, the control unit (280) only adjusts the tilting angle of the second intake port, and it is also possible to control the rotational speed of the first and second fan motors (112, 122) to the same third rotational speed.

[0360] If the received exhaust level is the third exhaust level, the fourth exhaust level, or the fifth exhaust level, the control unit (280) can adjust the tilting angle of the second intake based on the received exhaust level and also adjust the rotational speed of the first and second fan motors (112, 122).

[0361] More specifically, the control unit (280) may control the rotational speed of the first and second fan motors (112, 122) to a third rotational speed if the received exhaust level is a third exhaust level, control the rotational speed of the first and second fan motors (112, 122) to a fourth rotational speed if the received exhaust level is a fourth exhaust level, and control the rotational speed of the first and second fan motors (112, 122) to a fifth rotational speed if the received exhaust level is a fifth exhaust level.

[0362] Here, the fifth rotational speed can be faster than the fourth rotational speed. The fourth rotational speed can be faster than the third rotational speed. The third rotational speed can be faster than the second rotational speed.

[0363] The control unit (280) may stop the rotation of the first and second fan motors (112, 122) based on receiving an exhaust off command through the input unit (231), and may also control the drive motor (151) so that the second suction unit is accommodated inside the main body.

[0364] The control unit (280) can control the lighting unit (160) to turn off when an exhaust off command is received through the input unit (231).

[0365] <Automatic Exhaust Mode Control - Example 1>

[0366] When an exhaust on command is received through the input unit (231), the control unit (280) identifies the exhaust mode received through the input unit (231), and based on the fact that the identified exhaust mode is an automatic exhaust mode, determines the exhaust level based on at least one of the pollution level information received from the pollution level sensor (260), image information received from the sensor (261), and cooking information of the second cooking device (3) received through the communication unit (270), and controls the operation of at least one of the first and second fan motors (112, 122) and the drive motor (151) based on the determined exhaust level.

[0367] The control unit (280) can control the lighting unit (160) to turn on based on the operation of at least one of the first and second fan motors (112, 122) and the drive motor (151), and can control the lighting unit (160) to turn off based on the stopping of the first and second fan motors (112, 122) and the drive motor (151).

[0368] The control unit (280) may recognize a cooking zone in which food is being cooked among a plurality of cooking zones within the cooking area of ​​the second cooking device based on at least one of image information received from the image sensor (261), cooking information of the second cooking device received from the communication unit (270), and contamination information received from a plurality of contamination sensors (260a, 260b), and may also control exhaust based on location information of the recognized cooking zone. This will be explained with reference to FIGS. 14, 15, and 16.

[0369] As illustrated in FIG. 14, the control unit (280) recognizes a cooking zone where food is being cooked among a plurality of cooking zones within the cooking area of ​​the second cooking device based on image information received from the image sensor (261), controls the rotational speed of the first and second fan motors (112, 122) based on the position information of the recognized cooking zone, and can further control the tilting angle (An) of the second suction unit (140) based on the position information of the recognized cooking zone.

[0370] Controlling the tilting angle of the second suction part (140) may include controlling the rotation angle of the drive motor (151).

[0371] The image information received from the image sensor (261) may include thermal image information received from the thermal image sensor.

[0372] The control unit (280) can also recognize a cooking zone in which food is being cooked among a plurality of cooking zones within the cooking area of ​​the second cooking device (3) based on temperature information received from a plurality of temperature sensors.

[0373] As illustrated in FIG. 15, the control unit (280) recognizes a cooking zone in which food is being cooked among a plurality of cooking zones within a cooking area based on cooking information of the second cooking device received from the communication unit (270), controls the rotational speed of the first and second fan motors (112, 122) based on the location information of the recognized cooking zone, and it is also possible to additionally control the tilting angle (An) of the second suction unit (140) based on the location information of the recognized cooking zone.

[0374] As illustrated in FIG. 16, when a plurality of contamination sensors (260a, 260b) are provided, the control unit (280) recognizes a cooking zone in which food is being cooked among a plurality of cooking zones within the cooking area of ​​the second cooking device based on contamination information received from the plurality of contamination sensors (260a, 260b), controls the rotational speed of the first and second fan motors (112, 122) based on the location information of the recognized cooking zone, and it is also possible to additionally control the tilting angle (An) of the second suction unit (140) based on the location information of the recognized cooking zone.

[0375] For example, the control unit (280) can control the rotational speed of the first and second fan motors (112, 122) and the tilting angle of the second suction unit (140) if the recognized cooking zone is the front area of ​​the cooking area, and control the rotational speed of the first and second fan motors (112, 122) and the tilting angle of the second suction unit (140) to 0 degrees if the recognized cooking zone is the rear area of ​​the cooking area.

[0376] By controlling the tilting angle (An) of the second suction part (140), the opening of the suction port (145) of the second suction part (140) can be controlled.

[0377] When controlling the rotational speed of the first and second fan motors (112, 122), the control unit (280) controls the rotational speed of the first and second fan motors (112, 122) to a second rotational speed if the recognized cooking zone is the front area of ​​the cooking area, controls the rotational speed of the first and second fan motors (112, 122) to a first rotational speed if the recognized cooking zone is the rear area of ​​the cooking area, and controls the rotational speed of the first and second fan motors (112, 122) to a second rotational speed if the recognized cooking zone is both the front and rear areas of the cooking area.

[0378] When controlling the tilting angle of the second suction unit (140), the control unit (280) may also adjust the tilting angle based on the contamination level detected by the contamination level sensor (260). By adjusting the tilting angle (An) of the second suction unit (140), the opening of the suction port (145) of the second suction unit (140) can be adjusted.

[0379] For example, the control unit (280) may adjust the tilting angle to the first tilting angle if the contamination level detected by the contamination level sensor (260) is within the first standard contamination level range, adjust the tilting angle to the second tilting angle if the contamination level detected by the contamination level sensor (260) is within the second standard contamination level range, and adjust the tilting angle to the third tilting angle if the contamination level detected by the contamination level sensor (260) is within the third standard contamination level range.

[0380] In this embodiment, if a cooking zone exists in the front area of ​​the cooking area of ​​the second cooking device, contaminated air can be sucked in simultaneously through the first and second suction parts, and if a cooking zone exists in the rear area of ​​the cooking area of ​​the second cooking device, contaminated air can be sucked in intensively through the first suction part, thereby optimizing the suction and exhaust capabilities.

[0381] <Automatic Exhaust Mode Control - Example 2>

[0382] The control unit (280) can recognize the pollution level of the contaminated air based on pollution level information received from the pollution level sensor (260), determine the exhaust level based on the recognized pollution level of the contaminated air and a plurality of standard pollution level ranges, control the rotational speed of the first and second fan motors (112, 122) based on the determined exhaust level, and control the tilting angle of the second intake unit (140) based on the determined exhaust level.

[0383] For example, multiple standard pollution ranges may include a first standard pollution range, a second standard pollution range, and a third standard pollution range.

[0384] Pollution levels within the second standard pollution level range may be lower than pollution levels within the third standard pollution level range and higher than pollution levels within the first standard pollution level range.

[0385] For example, the control unit (280) can stop the first and second fan motors (112, 122) and stop the drive motor (151) if the pollution level of the recognized contaminated air is less than the minimum value of the first standard pollution level range.

[0386] For example, the control unit (280) can determine the exhaust level as the first exhaust level if the pollution level of the recognized polluted air falls within the first standard pollution level range, determine the exhaust level as the second exhaust level if the pollution level of the recognized polluted air falls within the second standard pollution level range, and determine the exhaust level as the third exhaust level if the pollution level of the recognized polluted air falls within the third standard pollution level range.

[0387] For example, if the determined exhaust level is the first exhaust level, the control unit (280) can control the rotational speed of the first and second fan motors (112, 122) to the first rotational speed and stop the drive motor (151). If the determined exhaust level is the second exhaust level, the control unit (280) can control the rotational speed of the first and second fan motors (112, 122) to the second rotational speed and stop the drive motor (151). If the determined exhaust level is the third exhaust level, the control unit (280) can control the rotational speed of the first and second fan motors (112, 122) to the second rotational speed and control the rotation angle of the drive motor (151) to a preset rotation angle.

[0388] The control unit (280) can control the rotational speed of the first and second fan motors (112, 122) to the third rotational speed if the determined exhaust level is the third exhaust level, and can also control the rotational angle of the drive motor (151) to a preset rotational angle. The preset rotational angle of the drive motor (151) can correspond to the preset tilting angle of the second suction unit.

[0389] <Automatic Exhaust Mode Control - Example 3>

[0390] The control unit (280) can identify the state of the pollution level as an increasing state of pollution based on the pollution level of the air increasing above a first reference value, and can identify the state of the pollution level as a decreasing state of pollution based on the pollution level of the air decreasing above a second reference value. The control unit (280) can identify the state of the pollution level as a maintaining state of pollution based on the pollution level of the air increasing below the first reference value or the pollution level of the polluted air decreasing below the second reference value.

[0391] The first reference value may include the first pollution level value or the rate of increase in pollution level.

[0392] The second standard value may include the second pollution level value or the reduction rate of the pollution level.

[0393] The control unit (280) can determine an exhaust level for automatic exhaust control based on whether the pollution level of the recognized contaminated air is in an increasing state, a maintaining state, or a decreasing state, and can control the rotational speed of the first and second fan motors (112, 122) based on the determined exhaust level, and can control the tilting angle of the second intake unit (140) based on the determined exhaust level.

[0394] Controlling the tilting angle of the second suction part (140) may include controlling the rotation angle of the drive motor (151).

[0395] The control unit (280) recognizes the rotation angle of the drive motor (151) based on position information received from the position sensor (156), and controls the maintenance of rotation or stopping of rotation of the drive motor (151) based on the recognized rotation angle of the drive motor (151), thereby allowing the rotation angle of the drive motor (151) to reach a preset rotation angle.

[0396] The preset rotation angle can be the reference rotation angle of the drive motor.

[0397] The configuration for controlling automatic exhaust in response to an increase or decrease in pollution levels is explained in more detail.

The standby mode may include stopping the first and second fan motors (112, 122) and controlling the tilting angle of the second suction unit (140) to 0 degrees.

[0402] Controlling the tilting angle of the second suction part (140) to 0 degrees may include accommodating the suction port of the second suction part (140) inside the main body of the first cooking device.

[0403] Controlling the tilting angle of the second suction part (140) to 0 degrees may include controlling the suction port (145) of the second suction part (140) to a closed state.

[0404] The control unit (280) can determine the exhaust level as the first exhaust level based on the fact that the contamination level of the cooking area is identified as being greater than or equal to the standard contamination level.

[0405] The control unit (280) can control the exhaust level starting from the lowest first exhaust level when the contamination level of the cooking area is identified as being above the standard contamination level. This allows the first cooking device to gradually draw in the contaminated air of the cooking area.

[0406] The control unit (280) identifies whether the pollution level of the contaminated air in the cooking area is increasing, maintaining, or decreasing based on pollution level information received from the pollution level sensor (260) while automatically controlling the exhaust at a determined exhaust level.

[0422] Controlling the tilting angle of the second suction part (140) to 0 degrees may include controlling the drive motor (151) to rotate in the second rotation direction by a preset rotation angle.

[0423] Controlling the tilting angle of the second suction part (140) to 0 degrees may include changing the second suction part from an exposed state to a receiving state.

[0424] The control unit (280) can also control the first and second fan motors (112, 122) to rotate at a higher third rotational speed than the second rotational speed based on the fact that the pollution level of the contaminated air is increasing during automatic exhaust control at the third exhaust level.

[0425] <Automatic Exhaust Mode Control - Example 4>

[0426] The control unit (280) may also adjust the tilting angle of the second suction unit (140) based on an increasing, maintaining, or decreasing state of the contamination level. In this case, the exhaust level may include one or more additional exhaust levels higher than the third exhaust level. In this embodiment, an example is described in which a fourth exhaust level and a fifth exhaust level higher than the third exhaust level exist.

[0427] The third exhaust level may be a preset exhaust level. The fourth exhaust level may be one level higher than the third exhaust level and one level lower than the fifth exhaust level.

[0428] The control unit (280) can control the first and second fan motors (112, 122) to a second rotational speed based on the determined exhaust level and adjust the tilting angle of the second suction unit (140) if the determined exhaust level is greater than or equal to a preset exhaust level. This will be explained in more detail.

[0431] The control unit (280) can control the first and second fan motors (112, 122) to a second rotational speed based on the fact that the exhaust level is a third exhaust level, and can control the tilting angle of the intake port (145) of the second intake unit (140) to a first tilting angle.

[0432] Controlling the tilting angle of the suction port (145) of the second suction part (140) to the first tilting angle may include controlling the rotation angle of the drive motor (151) to the first rotation angle and controlling it to rotate in the first rotation direction.

[0433] The control unit (280) can control the first and second fan motors (112, 122) to a second rotational speed based on the fact that the exhaust level is a fourth exhaust level, and can control the tilting angle of the intake port (145) of the second intake unit (140) to a second tilting angle.

[0434] Controlling the tilting angle of the suction port (145) of the second suction part (140) to the second tilting angle may include controlling the rotation angle of the drive motor (151) to the second rotation angle, but controlling it to rotate in the first rotation direction.

[0435] The control unit (280) can control the first and second fan motors (112, 122) to a second rotational speed based on the fact that the exhaust level is a fifth exhaust level, and can control the tilting angle of the intake port (145) of the second intake unit (140) to a third tilting angle.

[0436] Controlling the tilting angle of the suction port (145) of the second suction part (140) to a third tilting angle may include controlling the rotation angle of the drive motor (151) to a third rotation angle, but controlling it to rotate in a first rotation direction.

[0437] The second tilting angle may be larger than the first tilting angle and smaller than the third tilting angle.

[0438] The control unit (280) recognizes the rotational speed of the first and second fan motors corresponding to the degree of contamination of the contaminated air and controls the operation of the first and second fan motors at the recognized rotational speed, and it is also possible to recognize the tilting angle of the second intake unit corresponding to the degree of contamination of the contaminated air and control the drive motor (151) at the recognized tilting angle.

[0439] In the first cooking device of the present embodiment, when performing the automatic exhaust mode, the first and second fan motors are rotated at a first rotational speed, and as the degree of contamination of the contaminated air increases, the rotational speed of the first and second fan motors is rotated at a second rotational speed, thereby gradually increasing the rotational speed of the first and second fan motors. Through this, the operation of the first cooking device can be made stable.

[0440] As the tilting angle of the second suction part (140) increases, the opening of the suction port (145) of the second suction part (140) may increase. And, as the opening of the suction port (145) of the second suction part (140) increases, the proportion of contaminated air sucked into the second suction part (140) may increase, and the proportion of contaminated air sucked into the first suction part (130) may decrease relatively.

[0441] As illustrated in FIG. 17, when the ratio of contaminated air sucked into the second suction part (140) is A%, the ratio of contaminated air sucked into the first suction part (130) may be 100-A%. For example, when the ratio of contaminated air sucked into the second suction part (140) is 20% in response to the opening adjustment of the intake port (145) of the second suction part (140), the ratio of contaminated air sucked into the first suction part (130) may be 80%. For another example, when the ratio of contaminated air sucked into the second suction part (140) is 30% in response to the opening adjustment of the intake port (145) of the second suction part (140), the ratio of contaminated air sucked into the first suction part (130) may be 70%.

[0442] In this embodiment, the ratio of the amount of contaminated air sucked into the second suction part (140) and the amount of air sucked into the first suction part varies depending on the change in the opening of the suction port of the second suction part (140), but the total amount of contaminated air sucked through the first cooking device (2) may remain the same. As such, this embodiment can vary the ratio of the amount of contaminated air sucked through the front and bottom of the first cooking device, respectively, by adjusting the opening of the suction port of the second suction part (140).

[0443] The first cooking device of the present embodiment can guide contaminated air that moves out of the cooking area to the second intake part (140) while maintaining the size of the existing first cooking device (2), and accordingly, contaminated air can be sucked in more efficiently.
