Because the discharge port <NUM> of the ventilation device <NUM> is located between the heating device <NUM> and the user, the air discharged from the discharge port <NUM> toward the rear of the heating device <NUM> may block contaminated air from spreading to the user. That is, the air discharged from the discharge port <NUM> to the suction port <NUM> may form an "air curtain".

In addition, a plurality of blowers <NUM> and <NUM> may be provided in the ventilation device <NUM>. For example, the blower may be provided in each of a lower portion of the intake duct <NUM> and a lower portion of the exhaust duct <NUM>. The blower disposed downstream of the flow path 101a than the air purification device <NUM> may be referred to as a first blower <NUM> (a "discharge blower"). In addition, a second blower <NUM> (a "suction blower") may be provided upstream of the flow path 101a than the air purification device <NUM>. In this case, the air purification device <NUM> may be disposed between the first blower <NUM> and the second blower <NUM> along the flow path 101a. The first blower <NUM> may be disposed in the lower portion of the exhaust duct <NUM>, and the second blower <NUM> may be disposed in the lower portion of the intake duct <NUM>. The first blower <NUM> and the second blower <NUM> may operate independently of each other. The second blower <NUM> may suction contaminated air into the ventilation device body <NUM> through the suction port <NUM>. The first blower <NUM> may discharge air purified by the air purification device <NUM> to the outside of the ventilation device body <NUM> through the discharge port <NUM>. Meanwhile, the second blower <NUM> may be omitted. The first blower <NUM> and the exhaust duct <NUM> may be integrally formed and provided as one module or may be provided as separate modules. The second blower <NUM> and the intake duct <NUM> may also be integrally formed and provided as one module or may be provided as separate modules.

The ventilation device <NUM> may include the flow path 101a for guiding the air introduced through the suction port <NUM> to the discharge port <NUM>. The flow path 101a may be formed by the intake duct <NUM>, the exhaust duct <NUM>, and the housing <NUM>. The flow path 101a may be spaced apart from the heating device <NUM>. The housing <NUM> may be spaced apart from the heating device <NUM>.

A housing <NUM>-<NUM> may be coupled in communication with the heating device <NUM>, and the air discharged from the blower <NUM> may be guided to the heating device <NUM> by the flow path 101a-<NUM> formed by the housing <NUM>-<NUM>, to thereby cool the heating device <NUM>. In other words, the heating device <NUM> may be disposed on the flow path 101a-<NUM> of the ventilation device <NUM>-<NUM>, and the heating device <NUM> may be disposed downstream of the flow path 101a-<NUM> than the blower <NUM> and may be disposed upstream of the flow path 101a-<NUM> than the discharge port <NUM>. The air discharged from the blower <NUM> may, while cooling the heating device <NUM>, pass through the heating device <NUM>, to be guided to the discharge port <NUM> and discharged.

Although the blower <NUM> may be disposed inside the housing <NUM>-<NUM>, the disclosure is not limited thereto. The blower <NUM> including a blower fan <NUM> may be disposed in the heating device <NUM> disposed on the flow path 101a-<NUM>. In this case, the blower fan <NUM> may be referred to as a cooling fan of the heating device <NUM>, and the blower <NUM> and the blower fan <NUM> may be considered as a component of the heating device.

The third blower 130a-<NUM> and the fourth blower 130b-<NUM> may operate independently of each other. The third blower 130a-<NUM> and the fourth blower 130b-<NUM> may be controlled by a processor <NUM>. When the third blower 130a-<NUM> operates, air may be discharged through the first discharge port 103a formed in the first exhaust duct <NUM>, and when the fourth blower 130b-<NUM> operates, air may be discharged through the second discharge port 103b formed in the second exhaust duct <NUM>. The blower fan of the third blower 130a-<NUM> and the blower fan of the fourth blower 130b-<NUM> may rotate at the same or different speeds. The third blower 130a-<NUM> and the fourth blower 130b-<NUM> may supply air having the same or different flow rates to the first exhaust duct <NUM> and the second exhaust duct <NUM>, respectively. Accordingly, the first discharge port 103a and the second discharge port 103b may discharge air having the same or different flow rates.

For example, the first rotating device and the second rotating device (e.g., a motor) may be fixed to the third elevation device <NUM> and the fourth elevation device <NUM> (e.g., a scissor lift or a hydraulic cylinder). The first rotating device may be coupled to the first exhaust duct <NUM>, and the second rotating device may be coupled to the second exhaust duct <NUM>. By the third elevation device <NUM>, the first rotating device and the first exhaust duct <NUM> may be moved together in the upward and downward direction. By the fourth elevation device <NUM>, the second rotating device and the second exhaust duct <NUM> may be moved together in the upward and downward directions. In a state in which the first discharge port 103a is exposed to the upper area of the main body <NUM>, the first rotating device may rotate the first exhaust duct <NUM>.

The inductance of the heating coil measured when a container is placed on the upper portion of the heating coil is different from that measured when a container is not placed on the upper portion of the heating coil. In addition, sensing of the container may be performed by various methods.

The power supply <NUM> may receive power from an external power source, rectify the received power, and provide the rectified power to the components of the cooking apparatus <NUM>. The processor <NUM> may distribute the power transmitted from the power supply <NUM> to the intake duct <NUM>, the exhaust duct <NUM>, the discharge blower <NUM>, the suction blower <NUM>, the control panel <NUM>, the sensor <NUM>, and the oil mist collection device <NUM>, <NUM>, <NUM>, or <NUM>. Alternatively, the power supply <NUM> may directly supply power to each of the components of the cooking apparatus <NUM> under the control of the processor <NUM>.

The memory <NUM> may include a volatile memory (e.g., a static random-access memory (S-RAM) or a dynamic random-access memory (D-RAM)) and a nonvolatile memory (e.g., a read-only memory (ROM) or erasable prom (EPROM)). The processor <NUM> and the memory <NUM> may be implemented as separate chips or as a single chip. In addition, a plurality of processors and a plurality of memories may be provided.

The processor <NUM> may process data and signals using a program provided from the memory <NUM>, and may provide a control signal to each component of the cooking apparatus <NUM>. The processor <NUM> may include an arithmetic circuit, a memory circuit, and a control circuit. In addition, the processor <NUM> may include a single core or a plurality of cores.

The memory <NUM> may store programs, instructions, and data for controlling the operation of the cooking apparatus <NUM>. The processor <NUM> may generate a control signal for controlling the operation of the cooking apparatus <NUM> based on the program, instruction, and data memorized and/or stored in the memory <NUM>.

The memory <NUM> and the processor <NUM> may be provided inside the main body <NUM>, the housing <NUM>, the intake duct <NUM>, the exhaust duct <NUM>, or the heating device <NUM>. The processor <NUM> may control the operation of the blowers <NUM> and <NUM>, the movement of the intake duct <NUM>, and the movement of the exhaust duct <NUM> based on signals transmitted from the control panel <NUM> and/or the sensor <NUM>. For example, the processor <NUM> may control the first elevation device <NUM> to adjust the position of the intake duct <NUM>, and may control the second elevation device <NUM> to adjust the position of the exhaust duct <NUM>. In addition, the processor <NUM> may control the motors of the blowers <NUM> and <NUM> to adjust the rotation speed of the blower fan.

The processor <NUM> may adjust the positions of the intake duct <NUM> and the at least one exhaust duct <NUM>, based on identification of a container placed on the heater 3a (or a "burner") of the heating device <NUM>. The exhaust duct <NUM> may be provided in a single unit or a plurality of units thereof. Adjusting the position for each of the intake duct <NUM> and the exhaust duct <NUM> may include adjusting the elevation height and/or adjusting the rotation direction.

In addition, the processor <NUM> may select the heater 3a (which is called burner) to be operated based on a user input obtained by the control panel <NUM>. The processor <NUM> may adjust the respective positions of the intake duct <NUM> and the at least one exhaust duct <NUM> based on selection of the burner by the user input. That is, the processor <NUM> may determine the operation of the intake duct <NUM> and the operation of the at least one exhaust duct <NUM> based on the position of the burner to be controlled. The processor <NUM> may determine the position of the intake duct <NUM> and the position of the at least one exhaust duct <NUM> based on the position of the burner to be controlled. The processor <NUM> may adjust the position of the intake duct <NUM> and the position of the at least one exhaust duct <NUM> in consideration of both the selection of the burner by the user input and the identification of the container.

The processor <NUM> may adjust the elevation height for each of the intake duct <NUM> and the at least one exhaust duct <NUM> based on the size of the container. The processor <NUM> may adjust the elevation height for each of the intake duct <NUM> and the at least one exhaust duct <NUM> such that the suction port <NUM> of the intake duct <NUM> and the discharge port <NUM> of the exhaust duct <NUM> are located at positions higher than the position of the container. For example, the processor <NUM> may control the first elevation device <NUM> that raises or lowers the intake duct <NUM> to adjust the elevation height of the intake duct <NUM>. The processor <NUM> may control the second elevation device <NUM> that raises or lowers the exhaust duct <NUM> to adjust the elevation height of the exhaust duct <NUM>.

Air discharged from the discharge port <NUM> of the exhaust duct <NUM> needs to be moved to the suction port <NUM> of the intake duct <NUM>. However, when a movement path of the air is blocked by the container, the air discharged from the discharge port <NUM> may not reach the suction port <NUM>. In this case, contaminated air generated from the container during cooking may not move to the suction port <NUM>. In order to secure a movement path of the air discharged from the discharge port <NUM> of the exhaust duct <NUM>, the position for each of the intake duct <NUM> and the at least one exhaust duct <NUM> may be individually adjusted.

Meanwhile, the processor <NUM> may adjust the elevation height for each of the intake duct <NUM> and the at least one exhaust duct <NUM> based on an operation mode selected through the control panel <NUM>. The operation mode of the cooking apparatus <NUM> may include a pan mode and a pot mode. The pan mode is a mode for cooking using a container having a relatively small height, such as a frying pan. The pot mode is a mode for cooking using a container having a relatively large height, such as a pot. The elevation height for each of the intake duct <NUM> and the exhaust duct <NUM> in the pan mode may be smaller than the elevation height for each of the intake duct <NUM> and the exhaust duct <NUM> in the pot mode. The elevation height of the intake duct <NUM> and the elevation height of the exhaust duct <NUM> may be predetermined for each operation mode of the cooking apparatus <NUM>.

As shown in <FIG>, the exhaust duct <NUM> may be provided in a plurality of units thereof, and may include a first exhaust duct <NUM> and a second exhaust duct <NUM>. The first exhaust duct <NUM> may include a first discharge port 103a, and the second exhaust duct <NUM> may include a second discharge port 103b. The processor <NUM> may adjust the first elevation height of the intake duct <NUM> based on the size of the container placed on the heater 3a of the heating device <NUM> or the operation mode of the cooking apparatus. In addition, the processor <NUM> may adjust the second elevation height of the first exhaust duct <NUM> and the third elevation height of the second exhaust duct <NUM> to be the same or different based on the size of the container or the operation mode of the cooking apparatus. The pan mode or the pot mode may be separately set for each of the plurality of exhaust ducts <NUM> and <NUM>.

For example, containers having different sizes may be arranged on the first heater 3a-<NUM> adjacent to the first exhaust duct <NUM> and the second heater 3a-<NUM> adjacent to the second exhaust duct <NUM>, respectively. A pot having a relatively large height may be placed on the first heater 3a-<NUM>, and a pan having a relatively small height may be placed on the second heater 3a-<NUM>. In this case, the elevation height of the first exhaust duct <NUM> may be adjusted to be greater than the elevation height of the second exhaust duct <NUM>. Even when containers of different sizes are simultaneously arranged on the heating device <NUM>, spread of contaminated air may be effectively prevented by individually adjusting the positions of the plurality of exhaust ducts <NUM> and <NUM>.

In addition, the processor <NUM> may rotate the at least one exhaust duct <NUM> and <NUM> such that the discharge ports <NUM>, i.e., 103a and 103b face the container and/or the burner selected by the user input. The processor <NUM> may adjust the directions of the exhaust ducts <NUM> and <NUM> based on the position of the container. The processor <NUM> may adjust the first rotation angle of the first exhaust duct <NUM> and the second rotation angle of the second exhaust duct <NUM> such that the first discharge port 103a and the second discharge port 103b face the container. By allowing air discharged through the discharge port <NUM> to be directed toward the container, contaminated air generated from the container may be moved to the suction port <NUM> of the intake duct <NUM>.

The processor <NUM> may adjust the rotation speed of the at least one blower <NUM>, i.e., 130a-<NUM> and 130b-<NUM> based on at least one of the position of the container, the size of the container or a position of the burner selected by the user input. When the container and/or the selected burner is located at a relatively long distance from the discharge port <NUM>, the processor <NUM> may increase the rotation speed of the blower <NUM>. By increasing the flow rate and movement speed of air discharged through the discharge port <NUM>, contaminated air generated from a container located relatively far away from the discharge port <NUM> may be effectively prevented from spreading.

In addition, the amount of contaminated air generated from a larger container may be greater than the amount of contaminated air generated from a smaller container. That is, as the size of the container increases, the flow rate and movement speed of air discharged through the discharge port <NUM> need to be increased to prevent contaminated air from spreading. The processor <NUM> may, in order to increase the flow rate and movement speed of air discharged from the discharge port <NUM> toward the large container, increase the rotation speed of the blower <NUM>.

To correspond to the exhaust ducts <NUM> and <NUM> provided in plural, discharge blowers <NUM>, i.e., 130a-<NUM> and 130b-<NUM> may also be provided in plural. For example, the discharge blowers <NUM> may include a third blower 130a-<NUM> for flowing air into the first exhaust duct <NUM> and a fourth blower 130b-<NUM> for flowing air into the second exhaust duct <NUM>. The processor <NUM> may adjust the first rotation speed of the third blower 130a-<NUM> and the second rotation speed of the fourth blower 130b-<NUM> to be the same or different based on at least one of the position of the container, the size of the container or a position of the burner selected by the user input.

Some of the above-described components may be omitted from the cooking apparatus <NUM>. In addition, the cooking apparatus <NUM> may further include other components in addition to the above-described components.

In addition, the processor <NUM> may move the intake duct <NUM> and the at least one exhaust duct <NUM>, i.e., <NUM> and <NUM> upward based on at least one of the identification of the container or the selection of the burner (<NUM>). As the intake duct <NUM> and the at least one exhaust duct <NUM>, i.e., <NUM> and <NUM> are moved upward, the suction port <NUM> and the discharge port <NUM> may be exposed to the outside of the housing <NUM>.

The processor <NUM> may adjust the position for each of the intake duct <NUM> located on the first side of the heating device <NUM> and the at least one exhaust duct <NUM>, i.e., the first exhaust duct <NUM> and the second exhaust duct <NUM>, located on the second side of the heating device <NUM> opposite the first side of the heating device <NUM> based on at least one of the identification of the containe or the selection of the burner by the user input (<NUM>).

The processor <NUM> may adjust the elevation height for each of the intake duct <NUM> and the at least one exhaust duct <NUM> based on the size of the container or the operation mode of the cooking apparatus <NUM> (<NUM>). The processor <NUM> may adjust the elevation height for each of the intake duct <NUM> and the at least one exhaust duct <NUM> such that the suction port <NUM> of the intake duct <NUM> and the discharge port <NUM> of the exhaust duct <NUM> are located at positions higher than the position of the container. When the exhaust duct <NUM> is provided in a plurality of units thereof, the elevation height for each of the plurality of exhaust ducts <NUM> and <NUM> may be individually adjusted.

In addition, the processor <NUM> may rotate the at least one exhaust duct <NUM>, i.e., the first exhaust duct <NUM> and the second exhaust duct <NUM>, such that the discharge ports <NUM>, i.e., 103a and 103b of the exhaust ducts <NUM>, i.e., the first exhaust duct <NUM> and the second exhaust duct <NUM> face the container and/or the burner selected by the user input (<NUM>). The directions of the exhaust ducts <NUM> and <NUM> may be adjusted based on the position of the container and/or the position of the burner selected by the user input. When the exhaust duct <NUM> is provided in a plurality of units thereof, the rotation angle for each of the plurality of exhaust ducts <NUM> and <NUM> may be individually adjusted.

The processor <NUM> may operate at least one blower <NUM> and <NUM> positioned between the intake duct <NUM> and the exhaust duct <NUM> inside the housing <NUM> (<NUM> and <NUM>). At least one of a discharge blower <NUM> positioned in a lower portion of the exhaust duct <NUM> and a suction blower <NUM> positioned in a lower portion of the intake duct <NUM> may be provided inside the housing <NUM>. As the blowers <NUM> and <NUM> operate, air may be discharged through the discharge port <NUM> of the exhaust duct <NUM>, and the discharged air may be suctioned into the housing <NUM> through the suction port <NUM> of the intake duct <NUM>. The suctioned air may be purified while passing through the air purification device <NUM> and may be discharged back to the discharge port <NUM> of the exhaust duct <NUM>. In addition, when a plurality of discharge blowers 130a-<NUM> and 130b-<NUM> corresponding to the plurality of exhaust ducts <NUM> and <NUM> are provided, the rotation speed for each of the plurality of discharge blowers 130a-<NUM> and 130b-<NUM> may be individually adjusted.

<FIG> is a plan view of the cooking apparatus shown in <FIG>, which is viewed from the above.

Referring to <FIG>, a pot having a large height may be placed on the first heater 3a-<NUM>, and a frying pan having a small height may be placed on the second heater 3a-<NUM>. The positions of the intake duct <NUM>, the first exhaust duct <NUM>, and the second exhaust duct <NUM> may be adjusted based on the sizes and positions of the pot and the frying pan. In addition, the fourth heater 3a-<NUM> may be selected as a control target by the user input.

Because the size of the pot is larger than that of the frying pan, the elevation height of the intake duct <NUM> may be adjusted based on the height of the pot placed on the first heater 3a-<NUM>. The elevation height of the first exhaust duct <NUM> may be adjusted based on the height of the pot placed on the first heater 3a-<NUM>, and the elevation height of the second exhaust duct <NUM> may be adjusted based on the height of the frying pan placed on the second heater 3a-<NUM>.

In addition, as the first exhaust duct <NUM> and the second exhaust duct <NUM> rotate, the first direction of the first discharge port 103a and the second direction of the second discharge port 103b may be adjusted, and the air discharge direction may be adjusted. For example, the processor <NUM> may rotate the first exhaust duct <NUM> for the first discharge port 103a to face the first heater 3a-<NUM>, and may rotate the second exhaust duct <NUM> for the second discharge port 103b to face the second heater 3a-<NUM>. The second direction of the second discharge port 103b may be determined in consideration of the position of the fourth heater 3a-<NUM> selected as the control target by the user input.

In order that air is discharged toward a heater (e.g., the first heater 3a-<NUM>) selected through the control panel <NUM> among the plurality of heaters 3a, at least one of the rotation of the first exhaust duct <NUM> and the rotation of the second exhaust duct <NUM> may be adjusted. For example, when a larger amount of contaminated air is generated from the first heater 3a-<NUM>, at least one of the rotation angle of the first exhaust duct <NUM> and the second exhaust duct <NUM> may be adjusted such that the first discharge port 103a andr the second discharge port 103b faces the first heater 3a-<NUM>.

In addition, in order that the first discharge port 103a adjacent to the first heater 3a-<NUM> discharges air at a flow rate greater than that of air discharged through the second discharge port 103b, the rotation speed of the blower <NUM>,i.e., the third blower 130a-<NUM> and the fourth blower 130b-<NUM> may be adjusted. Accordingly, ventilation of the ventilation device <NUM>-<NUM> may be performed more efficiently.

As described above, by appropriately adjusting the positions of the intake duct <NUM> and the exhaust duct <NUM> provided around the heating device <NUM>, contaminated air generated during the cooking process may be blocked from spreading.

<FIG> is a plan view from above an example cooking apparatus including a ventilation device according to various embodiments of the present disclosure, which is viewed from the above. The construction of the ventilation device <NUM> described in <FIG> and <FIG> and the construction of the ventilation device <NUM>-<NUM> described in <FIG> may also be applied to a ventilation device <NUM>-<NUM> as shown in <FIG>.

Referring to <FIG>, a pan having a small size may be placed on the first heater 3a-<NUM>, and a pot having a large size may be placed on the second heater 3a-<NUM>. The size and heating power of the second heater 3a-<NUM> may be greater than the size and heating power of the first heater 3a-<NUM>.

An exhaust duct <NUM>-<NUM> of the ventilation device <NUM>-<NUM> may be provided to be movable in the upward and downward directions. The exhaust duct <NUM>-<NUM> may be provided to be rotatable in the left and right directions about a rotation axis extending in the upper-lower direction.

The exhaust duct <NUM>-<NUM> may be provided in a single unit, and when viewed from the above of the heating device <NUM>, the exhaust duct <NUM>-<NUM> may be disposed to be biased toward one side (e.g., the right side) with respect to a center in the left-right direction of the heating device <NUM>. A discharge port <NUM>-<NUM> of the exhaust duct <NUM>-<NUM> may be directed to face a part (e.g., the second heater 3a-<NUM>) of the plurality of heaters 3a-<NUM>, 3a-<NUM>, 3a-<NUM>, and 3a-<NUM>). Air discharged from the discharge port <NUM>-<NUM> may cause contaminated air generated from the second heater 3a-<NUM> to be moved toward the suction port <NUM>. The heater 3a corresponding to the discharge port <NUM>-<NUM> of the exhaust duct <NUM>-<NUM> may be set in advance, or may be determined by a selection of a user.

Air discharged from the discharge port <NUM>-<NUM> of the exhaust duct <NUM>-<NUM> may form an air curtain. That is, the air discharged from the discharge port <NUM>-<NUM> may prevent oil mist generated from a container placed on the heater 3a from spreading. The air discharged from the discharge port <NUM>-<NUM> may cover at least one of the plurality of heaters 3a-<NUM>, 3a-<NUM>, 3a-<NUM>, and 3a-<NUM>. When the exhaust duct <NUM>-<NUM> is provided in a single unit, the volume of the ventilation device <NUM>-<NUM> may be reduced, and power consumption may be reduced.

<FIG>, <FIG>, and <FIG> illustrate oil mist collection device according to various embodiments. In <FIG>, <FIG> and <FIG>, oil mist collection devices <NUM>, <NUM>, and <NUM> according to various embodiments are illustrated as provided in the ventilation device <NUM>, but the oil mist collection devices <NUM>, <NUM>, and <NUM> may be provided in the ventilation device <NUM>', <NUM>-<NUM>, <NUM>-<NUM>, and <NUM>-<NUM> according to other embodiments described above.

<FIG> illustrates the oil mist collection device <NUM> according to various embodiments of the present disclosure.

Referring to <FIG>, the oil mist collection device <NUM> may include a collecting member <NUM> allowing oil mist separated from air to adhere thereto and an ionizer <NUM> provided to charge oil mist of contaminated air.

The collecting member <NUM> may be in contact with air flowing through the inside of the ventilation device body <NUM>. The collecting member <NUM> may be disposed on the flow path 101a. The collecting member <NUM> may be formed of a conductive material (e.g., aluminum, copper, stainless steel, etc.). The collecting member <NUM> may be formed of a metal material.

The collecting member <NUM> may include a plate <NUM>. The plate <NUM> may have a substantially quadrangular flat plate shape. The plate <NUM> may be disposed in parallel with the direction of the airflow flowing through the flow path 101a. Specifically, the plate <NUM> may be disposed inside the housing <NUM> (e.g., inside the purification device receiver 104a), and may be disposed vertically or horizontally to be parallel with the direction of the airflow inside the housing <NUM> (e.g., inside the purification device receiver 104a). However, the disclosure is not limited thereto, and the collecting member <NUM> may include a conventional heat sink including a plurality of fins, a refrigerant tube, and the like.

The ionizer <NUM> may be provided to be in contact with the air flowing through the inside of the ventilation device body <NUM>. The ionizer <NUM> may be disposed on the flow path 101a. The ionizer <NUM> may be disposed upstream of the flow path 101a than the collecting member <NUM> (e.g., the plate <NUM>). The ionizer <NUM> may be disposed inside the purification device receiver 104a. However, the disclosure is not limited thereto, and the ionizer <NUM> may be disposed inside the intake duct receiver 104b and/or inside the intake duct <NUM>.

The ventilation device <NUM> may include a power supply <NUM> (or "power") provided outside or inside the ventilation device body <NUM> and serving to supply power to the ionizer <NUM> and/or charge the plate <NUM>. The power supply <NUM> may be electrically connected to the ionizer <NUM> and/or the plate <NUM>.

The ionizer <NUM> may charge oil mist in the air flowing into the flow path 101a through the suction port <NUM>. The charged oil mist may be caused to flow toward the charged collecting member <NUM> (e.g., the plate <NUM>), and the charged oil mist may adhere to the surface of the collecting member <NUM> by electrostatic attraction. The collecting member <NUM> may obtain heat from the oil mist, which adheres to the collecting member <NUM>, to condense the oil mist. That is, the condensed oil mist may adhere to the surface of the collecting member <NUM> (e.g., the plate <NUM>). Because the oil mist on the surface of the collecting member <NUM> is condensed into oil droplets, even when the collecting member <NUM> (e.g., the plate <NUM>) is not charged due to failure of electricity supply to the collecting member <NUM>, the oil mist may not return to the air and may be removed from the air.

Referring to <FIG>, the oil mist collection device <NUM> may include a collecting member <NUM> allowing oil mist separated from air to adhere thereto, a water tank <NUM> disposed below the collecting member <NUM> and accommodating water, and a water vapor generating device <NUM> for evaporating water in the water tank <NUM>.

The collecting member <NUM> may be provided to be in contact with the air flowing through the inside of the ventilation device body <NUM>. The collecting member <NUM> may be disposed on the flow path 101a.

The collecting member <NUM> may be formed of a thermally conductive material. The collecting member <NUM> may be formed of a metal material (e.g., aluminum, copper, stainless steel, etc.). However, the disclosure is not limited thereto, and the collecting member <NUM> may be formed of a material, such as plastic or glass.

The collecting member <NUM> may include a plate <NUM>. The plate <NUM> may have a substantially quadrangular flat plate shape. The plate <NUM> may be disposed in parallel with the direction of the airflow flowing through the flow path 101a. Specifically, the plate <NUM> may be disposed inside the housing <NUM> (e.g., the purification device receiver 104a), and may be disposed vertically or horizontally to be parallel with the direction of the airflow inside the housing <NUM> (e.g., inside the purification device receiver 104a).

The water tank <NUM> may be disposed below the collecting member <NUM>. The water tank <NUM> may be detachably disposed inside the housing <NUM> (e.g., inside the purification device receiver 104a). The water tank <NUM> may contain water.

The water vapor generating device <NUM> may be disposed inside the housing <NUM> (e.g., inside the purification device receiver 104a). The water vapor generating device <NUM> may be operated by receiving power from a power source (or "power supply") provided outside the ventilation device body <NUM>. The water vapor generating device <NUM> may receive water from the water tank <NUM>. At least a portion of the water vapor generating device <NUM> may be submerged in the water of the water tank <NUM>. The water vapor generating device <NUM> may vaporize water using heat or ultrasonic waves. However, the disclosure is not limited thereto, and the water vapor generating device <NUM> may be variously provided as long as it can generate water vapor based on various mechanisms.

The water vapor generated by the water vapor generating device <NUM> may be mixed with oil mist and condensed on the surface of the collecting member <NUM> (e.g., the plate <NUM>), and the oil mist may be removed from the contaminated air. In addition, the oil mist may come in direct contact with the water of the water tank <NUM> to thereby be condensed and removed from the contaminated air.

The collecting member <NUM> (e.g., the plate <NUM>) may include a guide curved surface 411a that guides water droplets, which adhere to the surface of the collecting member <NUM> and contain condensed oil, to the water tank <NUM>. The guide curved surface 411a may include a plurality of guide curved surfaces 411a. Specifically, the guide curved surface 411a may form a lower surface of the collecting member <NUM>, and may approach the water tank <NUM> as extending from the rear end of the collecting member <NUM> toward the front side or as extending from the front end of the collecting member <NUM> toward the rear side.

An end of the guide curved surface 411a closest to the water tank <NUM> may be spaced apart from the surface of the water contained in the water tank <NUM> by a predetermined distance t. Air in the flow path 101a may flow through a gap t between the one end of the guide curved surface 411a and the surface of the water.

Referring to <FIG>, the oil mist collection device <NUM> may include a collecting member <NUM> allowing oil mist separated from air to adhere thereto and a water tank <NUM> disposed below the collecting member <NUM> and receiving water.

The collecting member <NUM> may include a plurality of holes 511a formed through a surface thereof. The plurality of holes 511a may be formed to have a predetermined depth from the surface of the collecting member <NUM> or may be formed to pass through the collecting member <NUM>.

The collecting member <NUM> may include a cylinder <NUM> having the plurality of holes 511a formed on a surface thereof. The cylinder <NUM> may be rotatable about a central axis. The oil mist collection device <NUM> may include a rotating device (not shown) provided to rotate the cylinder <NUM> by receiving power from a power source (or "power supply") provided outside the ventilation device body <NUM> and including a motor. The cylinder <NUM> may be rotated by the rotating device. The cylinder <NUM> may be disposed inside the housing <NUM> (e.g., inside the purification device receiver 104a), and the central axis of the cylinder <NUM> may be perpendicular to the direction of an airflow inside the housing <NUM> (e.g., the purification device receiver 104a).

The water tank <NUM> may be disposed below the collecting member <NUM>. The water tank <NUM> may be detachably disposed inside the housing <NUM> (e.g., inside the purification device receiver 104a), and the water tank <NUM> may contain water.

At least a portion of the collecting member <NUM> (e.g., the cylinder <NUM>) may be submerged in the water of the water tank <NUM>. The cylinder <NUM> may be rotated with a portion thereof submerged in water. Water of the water tank <NUM> may permeate into the plurality of holes 511a submerged in water of the water tank <NUM>, and as the cylinder <NUM> rotates, the plurality of holes 511a may transport the water of the water tank <NUM> upward of the water level such that the water may be exposed to the flow path 101a. In addition, the collecting member <NUM> (e.g., the cylinder <NUM>) may be cooled by the water of the water tank <NUM>.

The collecting member <NUM> (e.g., the cylinder <NUM>) may cause the water permeating in the hole 511a to come in contact with oil mist, and the oil mist in contact with the water permeating in the hole 511a may be condensed and removed from the contaminated air. In addition, oil mist may come in direct contact with the water of the water tank <NUM> to be condensed and removed from the contaminated air. In addition, on the surface of the collecting member <NUM> (e.g., the cylinder <NUM>) kept cold by the water of the water tank <NUM>, oil mist may be condensed and removed from the contaminated air.

As described above, the cooking apparatus and the method of controlling the same according to the embodiment may effectively prevent contaminated air generated during the cooking process from spreading.

The cooking apparatus and the method of controlling the same according to the embodiment may block the spread of contaminated air generated during the cooking process by appropriately adjusting the positions of the intake duct and the exhaust duct provided around the heating device.
