[0059] The cooktop 10 may include a heating element 16. The heating element 16 may be configured as a heating plate 11. The heating element 16 may be arranged below the plate 11. For example, the heating element 16 may include a coil 16a. A current whose magnitude varies with time can be applied to the coil 16a. As current is applied to the coil 16a, a magnetic field can be formed around the coil 16a. As the current applied to the coil changes, the magnetic field formed around the coil 16a can also change. Eddy currents, generated according to the changing magnetic field, can flow on the surface of the cooking container in contact with the plate 11, thereby heating the cooking container.

[0060] Although the accompanying drawings show the cooktop 10 as an induction cooktop, it is not limited to this. The type of cooktop 10 is not limited as long as it can heat cooking containers. For example, the cooktop 10 can be equipped with a gas stove, a high-brightness stove (e.g., a ceramic stove), a combination stove, or an oven.

[0061] The cooktop 10 may include a printed board assembly (PBA) 17. The PBA assembly 17 may be equipped with drive current for supplying drive current to the heating element 16.

[0063] For example, an intake port 19a and an exhaust port 19b may be formed in the housing 13. For example, the intake port 19a may be formed at the bottom 13a of the housing 13. For example, the exhaust port 19b may be formed at the side 13b of the housing 13. External air can flow into the housing 13 through the intake port 19a by the airflow from the fan 18, and then flow out to the outside of the housing 13 through the exhaust port 19b. Although the accompanying drawings show a case where multiple intake ports 19a and exhaust ports 19b are formed, this is not a limitation. There is no limitation on the number of intake ports 19a and exhaust ports 19b.

[0064] Cooking appliance 1 may include a cover 20. Cover 20 allows airflow through inlet 12. Cover 20 can guide the airflow through inlet 12. Cover 20 can exhaust or recirculate the airflow through inlet 12. Cover 20 can exhaust the airflow through inlet 12 to the outside of the space (e.g., indoors) where cooking appliance 1 is located. Cover 20 can recirculate the airflow through inlet 12 back into the space (e.g., indoors) where cooking appliance 1 is located. In other words, cover 20 can guide the airflow through inlet 12 to the outside or to the inside. As described later, at least one filter 61 and / or 71 may be provided inside cover 20. Air flowing in cover 20 can pass through and be filtered by at least one filter 61 and / or 71.

Figure 9 This is an enlarged view of the upper part of a cooking apparatus according to one embodiment. Figure 10 This is an exploded perspective view of a cooking apparatus according to one embodiment. Figure 11 This is an enlarged view of a cooking apparatus according to one embodiment. Figure 12 This is an exploded perspective view of a cooking apparatus according to one embodiment.

[0092] Figure 10 A drive unit, connector, and cover according to one embodiment are shown. Figure 11 Enlarged display Figure 10 A diagram showing a portion of the cover. Figure 12 Shown from another direction Figure 10 The cooking equipment shown includes a drive unit, connector, and cover.

[0093] Reference Figures 8 to 12 The cooking apparatus 1 may include a drive unit 200. The drive unit 200 may be configured to generate a driving force. The driving force generated from the drive unit 200 may be transmitted to the lid 100. The drive unit 200 may be configured to move the lid 100. The drive unit 200 may be configured to rotate the lid 100. Thus, the lid 100 may operate in a manner that covers and / or closes the suction port 12 or opens the suction port 12.

[0094] At least a portion of the drive unit 200 may be disposed inside the cooktop 10, and another portion of the drive unit 200 may be disposed inside the cover 20. For example, at least a portion of the drive unit 200 may be disposed inside the housing 13, and another portion of the drive unit 200 may be disposed inside the chamber housing 30. However, it is not limited to this, and can be disposed in various positions as long as the drive unit 200 can drive the cover 100.

The connector 300 can be secured by a fastening member during insertion into the first insertion hole 2161. The connector can be secured to the frame from the inside of frame 210.

[0100] Although the accompanying drawings show the frame 210 including two first insertion holes 2161a and 2161b, the design is not limited thereto. The number of first insertion holes 2161 may correspond to the number of cover components.

[0101] The frame 210 may include a second insertion hole 2162. An insertion protrusion 150 of the cover 100 (described later) can be inserted into the second insertion hole 2162. The second insertion hole 2162 may be formed on the other side of the frame 210. For example, the second insertion hole 2162 may be formed through the rear sidewall 2102b of the frame 210. However, it is not limited to this; a connector 300 may also be inserted into the second insertion hole 2162. For example, both ends of the cover 100 along its length can be connected to the frame 210 via the connector 300.

[0102] Although the accompanying drawings show the frame 210 including two second insertion holes 2162a and 2162b, the invention is not limited thereto. The number of second insertion holes 2162 may correspond to the number of cover components described later.

[0103] Furthermore, although the aforementioned case describes the frame 210 as a component of the drive unit 200, it is not limited thereto. The frame 210 may also be configured as a component separate from the drive unit 200.

[0104] Frame 210 may include position guide protrusions 217 and 219. Position guide protrusions 217 and 219 can guide the position of lever 260. For example, position guide protrusions 217 and 219 can guide the position of lever 260 at a first cover position P1 where cover 100 closes the suction port 12, or at a second cover position P2 where cover 100 opens the suction port 12. Since lever 260 is linked to connector 300 and moving part 250, position guide protrusions 217 and 219 can also guide the position of connector 300 and moving part 250.

[0105] Position guide protrusions 217 and 219 can be configured in multiple ways. Multiple position guide protrusions may include a first position guide protrusion 217 and a second position guide protrusion 219.

[0106] The first position guide protrusion 217 can guide the position of the lever 260 at the first cover position P1 where the cover 100 closes the suction port 12. The first position guide protrusion 217 can contact the lever 260 to prevent the lever 260 from rotating further upward. For example, the lower surface of the first position guide protrusion 217 can contact the upper surface of the lever 260.

[0107] The second position guide protrusion 219 can guide the position of the lever 260 at the second cover position P2 of the open intake port 12 of the cover 100. The second position guide protrusion 219 can contact the lever 260 to prevent the lever 260 from rotating further downward. For example, the side of the second position guide protrusion 219 can contact the lower surface of the lever 260.

[0108] The drive unit 200 may include a motor 220. The motor 220 may generate rotational force and / or power. The motor 220 may provide rotational force and / or power to the cam 230. The motor 220 may include a motor shaft 221. The motor shaft 221 may be coupled to and / or mounted on the cam 230.

[0109] The drive unit 200 may include a cam 230. The cam 230 may be connected to a motor 220. The cam 230 may receive rotational force and / or power from the motor 220. The cam 230 may rotate in conjunction with the motor 220.

[0110] The cam 230 may include a cam engagement portion 232 that engages with the motor shaft 221 of the motor 220. For example, the cam engagement portion 232 may be located at the center of the cam 230.

[0111] The cam 230 may include a camshaft 231 spaced apart from the cam engagement 232. As the cam 230 connected to the motor 220 rotates, the camshaft 231 may rotate about the cam engagement 232. As the cam 230 connected to the motor 220 rotates, the camshaft 231 may rotate about the motor shaft 221.

[0112] The cam 230 may include at least one cam protrusion 233 and / or 234. As the cam 230 rotates, at least one cam protrusion 233 and / or 234 may be configured to contact the switch 280 described later. For example, the cam 230 may include a first cam protrusion 233 and a second cam protrusion 234. The first cam protrusion 233 and the second cam protrusion 234 may have different lengths from each other.

[0113] The drive unit 200 may include a link 240. The link 240 may be connected to a cam 230. The link 240 may move in conjunction with the cam 230. For example, the link 240 may move in the vertical direction (Z direction).

[0114] The first end 241 of the connecting rod 240 can be connected to the camshaft 231. The first end 241 of the connecting rod 240 can rotate in conjunction with the camshaft 231. The first end 241 of the connecting rod 240 can rotate together with the camshaft 231. Therefore, the first end 241 of the connecting rod 240 can rotate about the motor shaft 221 of the motor 220. The first end 241 of the connecting rod 240 can be configured to rotate about the motor shaft 221 of the motor 220. The first end 241 of the connecting rod 240 can generally draw a circle and rotate.

[0115] The second end 242 of the link 240 can move vertically by rotating the first end 241 of the link 240. The second end 242 of the link 240 can move along a track formed in the frame 210. The second end 242 of the link 240 can reciprocate linearly. The second end 242 of the link 240 can be connected to the moving part 250.

[0116] The drive unit 200 may include a moving member 250. The moving member 250 may move in one direction. For example, the moving member 250 may slide in a vertical direction.

[0117] The movable component 250 may include a pressure portion 251. The pressure portion 251 may extend in one direction to pressurize the lever 260. For example, the pressure portion 251 may extend horizontally to pressurize a contact protrusion 261 of the lever 260 disposed below the pressure portion 251. The pressure portion 251 may contact the contact protrusion 261. The pressure portion 251 may be positioned above the movable component 252.

[0118] Multiple pressurizing portions 251 can be provided. For example, the multiple pressurizing portions 251a, 251b may include a first pressurizing portion 251a and a second pressurizing portion 251b. The first pressurizing portion 251a may extend in a horizontal direction. The second pressurizing portion 251b may be rotatably coupled to the first pressurizing portion 251a. The second pressurizing portion 251b may be coupled to both sides of the first pressurizing portion 251a.

[0119] Based on the operation of the motor 220, the pressing part 251 of the moving part 250 can pressurize the contact protrusion 261 of the lever 260. For example, in the initial stage when the cover 100 moves from the first cover position P1 to the second cover position P2, the first pressing part 251a can pressurize the contact protrusion 261, and then the second pressing part 251b can pressurize the contact protrusion 261.

[0120] The movable component 250 may further include a movable part 252. The movable part 252 may be arranged below the pressurizing part 251. The movable part 252 may extend in a vertical direction. The movable part 252 may slide in a vertical direction. The movable part 252 may be a sliding part.

[0121] The movable component 250 can be connected to the second end 242 of the connecting rod 240. The movable component 250 is capable of moving vertically in conjunction with the second end 242 of the connecting rod 240. The movable component 250 can be configured to reciprocate linearly together with the second end 242 of the connecting rod 240. The movable component 250 can apply pressure to the lever 260 as it moves vertically. The movable component 250 can be referred to as a slider 250, a movable panel 250, and / or a movable block 250.

[0122] The drive unit 200 can convert rotary motion into linear reciprocating motion. For example, the motor 220, cam 230, and the first end 241 of the connecting rod 240 can rotate. For example, the second end 242 of the connecting rod 240 and the moving part 250 can reciprocate linearly.

[0123] The drive unit 200 may include a lever 260. The lever 260 may be pressed by a movable member 250. The lever 260 may rotate as it is pressed by the movable member 250. The lever 260 may extend in one direction. For example, the lever 260 may extend horizontally. One end of the lever 260 along its length may be configured to rotate about the other end of the lever 260.

[0124] Lever 260 can be attached to frame 210 on the outside of frame 210. Lever 260 can be arranged on the opposite side of connector 300 with reference to wall 2102a of frame 210.

[0125] Lever 260 can provide rotational force to cover 100. Lever 260 can cause cover 100 to rotate. A connector 300 connecting lever 260 and cover 100 can transmit the rotational force of lever 260 to cover 100. Connector 300 can be mounted on lever 260. Lever 260 can be detachably coupled to connector 300 to transmit force to connector 300. Lever 260, connector 300, and cover 100 can be configured to rotate together. However, lever 260 and connector 300 can be integrally formed to transmit rotational force to or receive rotational force from cover 100.

[0126] Lever 260 can guide the rotation and movement of cover 100 and / or connector 300. Lever 260 may be referred to as guide rod 260.

[0127] The lever 260 may include an extension 264. The extension 264 may extend in one direction. For example, during the period when the cover 100 is in the first cover position P1, the extension 264 may extend in a second direction B1 or B2. And, for example, during the period when the cover 100 is in the second cover position P2, the extension 264 may extend in a third direction C.

[0128] The lever 260 may include a contact protrusion 261 capable of contacting the movable member 250. The contact protrusion 261 may extend from and / or protrude from the extension 264. For example, the contact protrusion may protrude along a first direction A. As the movable member 250 moves downward (in the -Z direction), the contact protrusion 261 may be contacted and pressurized by the movable member 250.

[0129] The lever 260 may include a lever engagement portion 263 that can be coupled to the connector 300. The lever engagement portion 263 may be referred to as the rod engagement portion 263. The contact protrusion 261 of the lever 260 can rotate about the lever engagement portion 263 by applying pressure from the moving member 250. The contact protrusion 261 of the lever 260 can rotate approximately in an arc about the lever engagement portion 263. Thus, as the lever 260 is pressed and rotated by the moving member 250, the cover 100 can be operated in a manner that opens the suction port 12.

[0130] The lever 260 may include a movable protrusion 262 that moves along a path 2180 formed by the guide rib 218. The movable protrusion 262 may extend from and / or protrude from the extension 264. For example, the movable protrusion 262 may protrude in a direction D opposite to that of the contact protrusion 261. The movable protrusion 262 may be disposed inside the guide rib 218.

[0131] The movable protrusion 262 can contact the elastic member 270. A second end 272 of the elastic member 270 can be disposed below the movable protrusion 262, and an elastic force can be generated in the elastic member 270 based on the movement of the movable protrusion 262. At this time, the elastic force generated in the elastic member 270 can be a force that returns the lever 260 to its original position. The movable protrusion 262 can fix and support the second end 272 of the elastic member 270. The movable protrusion 262 can be referred to as a support protrusion and / or a fixing protrusion.

[0132] Lever 260 may include multiple levers 260a and 260b. The multiple levers 260a and 260b may include a first lever 260a and a second lever 260b. Each of the first lever 260a and the second lever 260b may include an extension 264, a contact protrusion 261, a lever engagement portion 263, and a movable protrusion 262.

[0133] Although the accompanying drawings show the drive unit 200 including two levers 260a and 260b, it is not limited thereto. The number of levers 260 may correspond to the number of cover components described later.

[0134] The drive unit 200 may include a resilient member 270. The resilient member 270 may be configured to resiliently bias the cover 100 and / or the lever 260. The resilient member 270 may include a spring 270.

[0135] The elastic member 270 can be configured to elastically bias the lever 260, causing the lever 260 to rotate in the opposite direction to the direction in which the lever 260 is pressed and rotated by the moving member 250. Furthermore, the moving member 250 and the elastic member 270 can be independent of each other. Additionally, the cover 100, connected to the lever 260 via the connector 300, can also rotate in conjunction with the lever 260.

[0136] For example, in response to the cover 100 rotating in a first rotational direction that opens the intake port 12, the connector 300 and the lever 260 can also rotate, and the elastic member 270 can pressurize the lever 260 and the cover 100 in a second rotational direction that closes the intake port 12.

[0137] In other words, the resilient member 270 can rotate the cover 100 in the direction of covering and / or closing the intake port 12, independent of the movement and position of the movable member 250. As the movable member 250 moves upward (in the -Z direction), the lever 260 can be unpressurized by the movable member 250. The lever 260, unpressurized by the movable member 250, can rotate in the direction of closing the intake port 12 by the elastic restoring force of the resilient member 270. Thus, as the lever 260 is elastically biased and rotated by the resilient member 270, the cover 100 can be operated in a manner that closes the intake port 12.

[0138] The resilient member 270 may be configured to surround the wall 2163 of the frame 210 forming the first insertion hole 2161. The resilient member 270 may include a first end 271 and a second end 272. The first end 271 of the resilient member 270 may be restricted in movement by a support protrusion 213. For example, the first end 271 of the resilient member 270 may contact the lower surface of the support protrusion 213. The second end 272 of the resilient member 270 may contact the movable protrusion 262 of the lever 260. For example, as the second end 272 of the resilient member 270 contacts the lower surface of the movable protrusion 262 of the lever 260, causing the lever 260 to rotate, the cover 100 may also rotate, and an elastic force may be generated in the resilient member 270. Based on the rotation of the lever 260, the resilient member 270 may generate a force that returns the lever 260 and the cover 100 to their previous positions.

[0139] In other words, the movable component 250 can not apply pressure to the cover 100 in the direction (above) where the cover 100 closes the suction port 12, and the elastic component 270 can apply pressure to the lever in the direction (above) where the cover 100 closes the suction port 12. Furthermore, when the user applies downward pressure to the cover 100 to open the suction port 12, the cover 100, lever 260, connector 300, and elastic component 270 can rotate without moving the movable component 250. And the elastic component 270 can apply pressure to the lever 260 in the direction where the cover 100 closes the suction port 12.

[0140] Therefore, even if the user's body is trapped between the first cover component 100a and the second cover component 100b, the user can apply downward pressure to the first cover component 100a and the second cover component 100b to increase the gap between them, thereby freeing the body. After the body is freed, the first cover component 100a and the second cover component 100b can return to the first cover position P1 by means of the elastic member 270. The cooking device according to one embodiment can prevent the user's body from being trapped between the first cover component 100a and the second cover component 100b and thus prevent injury.

[0141] Although the accompanying drawings show the drive unit 200 including two elastic members 270a and 270b, it is not limited thereto. The number of elastic members 270 may be the same as the number of cover members described later.

[0142] Furthermore, although the illustration shows multiple elastic components 270a and 270b including first ends 271a and 271b and second ends 272a and 272b respectively, it is not limited to this.

[0143] The drive unit 200 may include a switch 280. The switch 280 may be arranged adjacent to the cam 230. The switch 280 may be configured to sense the rotational position of the cam 230. The switch 280 may be configured to contact at least one cam protrusion 233 and / or 234 of the cam 230. The switch 280 may be configured to be turned on / off upon contact with at least one cam protrusion 233 and / or 234 of the cam 230. The cooking appliance may determine the position of the lid 100 based on the on / off state of the switch 280. For example, the control unit of the cooking appliance may determine whether the lid 100 is open or closed at the suction port 12. Although two switches 280 are shown in the figures, the invention is not limited thereto. One switch 280 or more switches 280 may be provided.

[0144] The cooking appliance 1 may include a connector 300. The connector 300 can connect the drive unit 200 and the lid 100. The connector 300 may be configured to transmit power from the drive unit 200 to the lid 100. The connector 300 can rotate by the power generated from the drive unit 200. The lid 100, which is attached to the connector 300, can rotate together with the connector 300. Thus, the lid 100 can be operated in a manner that closes or opens the suction port 12.

[0145] One side of the connector 300 can be coupled to the drive unit 200, and the other side of the connector 300 can be coupled to the cover 100.

[0146] The connector 300 may include a shaft portion 331 that can be inserted into a first insertion hole 2161 of the frame 210. For example, the shaft portion 331 is capable of moving along a first direction A (refer to...). Figure 8 and Figure 10 The shaft portion 331 is inserted into the first insertion hole 2161. The shaft portion 331 can be inserted into the first insertion hole 2161 and connected to the lever 260. For example, the end portion 3311 of the shaft portion 331 can be detachably coupled to the lever engagement portion 263 of the lever 260.

[0147] The connector 300 may include a coupling protrusion 333. The coupling protrusion 333 of the connector 300 can be separably engaged with the coupling groove 140 of the cover 100, described later. The coupling protrusion 333 and the coupling groove 140 may have corresponding shapes. The coupling protrusion 333 may extend and / or protrude from the shaft portion 331. The coupling protrusion 333 may extend and protrude from the shaft portion 331 in a left-right direction (e.g., Y, -Y). As described later, when the connector 300 includes a shield portion 332, the coupling protrusion 333 may extend and protrude from the shield portion 332 in a left-right direction (e.g., Y, -Y). For example, the coupling protrusion 333 may extend from the shaft portion 331 in a second direction B1 or B2 intersecting the first direction A (see reference). Figure 8For example, in the case of connector 300a, the connecting protrusion 333 can extend from the shaft portion 331 along a second direction B1 that intersects the first direction A. For example, in the case of connector 300b, the connecting protrusion 333 can extend from the shaft portion 331 along a second direction B2 that intersects the first direction A.

[0148] The connecting protrusion 333 can be rotatably mounted around the shaft portion 331 inserted into the first insertion hole 2161. The connecting protrusion 333 can be rotated approximately in an arc around the shaft portion 331 inserted into the first insertion hole 2161.

[0149] The connector 300 may include a retaining protrusion 334. The retaining protrusion 334 secures the engaging protrusion 333 into the engaging groove 140. The retaining protrusion 334 may be formed in the engaging protrusion 333. For example, the retaining protrusion 334 may protrude from one end of the engaging protrusion 333. The retaining protrusion 334 of the connector 300 may be configured to engage with the retaining groove 160 of the cover 100. During engagement of the retaining protrusion 334 of the connector 300 with the retaining groove 160 of the cover 100, the cover 100 may not be easily detached from the connector 300. During engagement of the retaining protrusion 334 of the connector 300 with the retaining groove 160 of the cover 100, the cover 100 may not detach from the connector 300. During the engagement of the fixing protrusion 334 of the connector 300 with the fixing groove 160 of the cover 100, the cover 100 can operate without shaking during the opening and closing of the suction port 12, and the cover 100 can operate stably.

[0150] The joint portion 120 of the cover 100 may include a groove forming portion 124. For example, the groove forming portion 124 may be formed on the second rib 122 in a manner that forms a fixing groove 160. The groove forming portion 124 may include a step.

[0151] The connector 300 may include a shield 332. The shield 332 may extend from the shaft portion 331. For example, the shield 332 may be disposed between the shaft portion 331 and the engagement protrusion 333. The shield 332 may be configured to cover the first insertion hole 2161. The shield 332 may be larger than the first insertion hole 2161. The shield 332 may have a larger size than the first insertion hole 2161. For example, the diameter of the shield 332 may be larger than the diameter of the first insertion hole 2161. The first insertion hole 2161 into which the connector 300 is inserted can be sealed. Thus, air flowing in the flow path 210f can be prevented from flowing out through the first insertion hole 2161. Air guided by the frame 210 can not flow out through the first insertion hole 2161. As a result, pollutants contained in the air can be prevented from penetrating into the internal space 13c of the housing 13, various components of the drive device 200, etc.

[0152] The connector 300 may include a plurality of connectors 300a and 300b. The plurality of connectors 300a and 300b may include a first connector 300a and a second connector 300b. Each of the first connector 300a and the second connector 300b may include a shaft portion 331, a shield portion 332, a connecting protrusion 333, and a fixing protrusion 334.

[0153] Although the accompanying drawings show the cooking apparatus 1 including two connectors 300a and 300b, it is not limited thereto. The number of connectors 300 may be the same as the number of lid components described later.

[0154] Cooking appliance 1 may include a lid 100. Lid 100 may include at least one lid member 100a and / or 100b. Lid members 100a and 100b may extend in a direction, for example, extending longer in said direction than in the width direction. For example, lid members 100a and 100b may extend in a horizontal direction. For example, lid members 100a and 100b may extend in a front-to-back direction.

[0155] Although the accompanying drawings show a case where the cover 100 includes a first cover component 100a and a second cover component 100b arranged in a generally horizontal direction (Y direction), this is not the limitation. For example, the cover 100 may include a single cover component, which may have a size corresponding to the inlet 12. For example, the first cover component 100a and the second cover component 100b may be arranged in a generally front-back direction (X direction). For example, the cover 100 may include more than three cover components. Cover components may be provided in various numbers, shapes, and / or arrangements. Hereinafter, for ease of explanation, an example of the cover 100 including the first cover component 100a and the second cover component 100b will be described.

[0156] In the accompanying drawings, reference numerals for the configuration of the first cover member 100a and / or the configuration corresponding to the first cover member 100a may be designated as "a". In the accompanying drawings, reference numerals for the configuration of the second cover member 100b and / or the configuration corresponding to the second cover member 100b may be designated as "b". For example, lever 260a, connector 300a, elastic member 270a, first insertion hole 2161a, second insertion hole 2162a, etc., may be configured to correspond to the first cover member 100a. For example, lever 260b, connector 300b, elastic member 270b, first insertion hole 2161b, second insertion hole 2162b, etc., may be configured to correspond to the second cover member 100b.

[0157] The first cover component 100a and the second cover component 100b may be symmetrically arranged. The first cover component 100a and the second cover component 100b may be arranged symmetrically with respect to the vertical center line V of the inlet 12. The first cover component 100a and the second cover component 100b may have substantially the same shape.

[0158] The following description of one of the first cover component 100a and the second cover component 100b can be applied to the description of the other of the first cover component 100a and the second cover component 100b. The following description of cover 100 can be applied to both the first cover component 100a and the second cover component 100b. For ease of explanation, the following description of cover 100 can be replaced with descriptions of each cover component individually.

[0159] The cover 100 can be detachably attached to the connector 300. The connector 300 can be inserted into or removed from the cover 100. The cover 100 can be linked with the connector 300 to close or open the suction port 12. The cover 100 can rotate together with the connector 300. As the connector 300 rotates by the drive device 200, the cover 100 connected to the connector 300 can also rotate.

[0160] The cover 100 may include a cover panel 110. The cover panel 110 may be configured to correspond to the suction port 12. The cover panel 110 may have a shape that extends in a manner that covers the suction port 12. For example, the cover panel 110 may extend in a front-rear direction.

[0161] For example, the cover panel 110 may have a generally plate-like shape. For example, the cover panel 110 may include a first edge portion 111, a second edge portion 112, a third edge portion 113, and a fourth edge portion 114. For example, the first edge portion 111 and the second edge portion 112 may be configured as long sides. For example, the third edge portion 113 and the fourth edge portion 114 may be configured as short sides. For example, the third edge portion 113 may be configured on the side of the drive device 200 adjacent to the lever 260. For example, the fourth edge portion 114 may be configured on the opposite side of the third edge portion 113. For example, the cover panel 110 may have a shape that is longer in the front-rear direction (X direction) and shorter in the horizontal direction (Y direction). However, the cover panel 110 is not limited to the above examples, and the cover panel 110 may have various shapes.

[0162] The cover 100 may include a first cover extension 120. The first cover extension 120 may extend from the cover panel 110. The first cover extension 120 may extend from a first side of the cover panel 110. For example, the first cover extension 120 may extend from a third edge 113 of the cover panel 110. For example, the first cover extension 120 may extend from the third edge 113 along a third direction C intersecting the first direction A and the second direction B. For example, the first cover extension 120 may extend downward from one end of the cover panel 110 along its length direction.

[0163] The cover 100 may include a connecting portion 120. For example, the first cover extension 120 may serve as the connecting portion 120. The connecting portion 120 allows the connector 300 to engage with the cover 100. The connecting portion 120 may include a connecting groove 140. For example, the connecting groove 140 may be formed in the first cover extension 120. The connector 300 may engage and / or be inserted into the connecting groove 140. The connecting groove 140 of the cover 100 may be detachably engaged with the connecting protrusion 333 of the connector 300. The connecting groove 140 of the cover 100 may have a shape corresponding to the connecting protrusion 333 of the connector 300. For example, the connecting groove 140 of the cover 100 may extend along the extending direction of the third edge portion 113 of the cover panel 110.

[0164] Although the illustration describes a scenario where a connecting portion 120, including a connecting groove 140, is provided on the cover 100 and the connector 300 is inserted into the connecting groove 120, the illustration is not limited thereto. The connector 300 may include a connecting groove, and the cover 100 may also have a connecting portion that protrudes in a manner that is inserted into the connector 300.

[0165] The first cover extension 120 may include a first rib 121 adjacent to the cover panel 110. The first cover extension 120 may include a second rib 122 spaced apart from the first rib 121. The second rib 122 may be spaced apart from the first rib 121 across the mating groove 140. The second rib 122 may be spaced apart from the first rib 121 in a third direction C. The first cover extension 120 may include a third rib 123 connecting the first rib 121 and the second rib 122. The first cover extension 120 may be referred to as the mating portion 120 forming the mating groove 140.

[0166] The mating groove 140 may include a first groove portion 141 configured to be surrounded by a first rib 121, a second rib 122, and a third rib 123. The mating groove 140 may also include a second groove portion 142 configured to be open on the side opposite to the first groove portion 141. For example, the second groove portion 142 may correspond to a portion of the mating groove 140 not surrounded by the first rib 121, the second rib 122, and the third rib 123. The area of ​​the second groove portion 142 may tend to increase in a second direction. For example, the mating groove 140 may include a generally U-shaped portion.

[0167] The cover 100 may include a guide 180. The connecting portion 120 may include a guide 180. The guide 180 may guide the connector 300 to engage with the connecting portion 120. For example, the guide 180 may guide the connector 300 into the connecting groove 140. The guide 180 may be disposed adjacent to the second groove 142. The guide 180 may be arranged further away from the third rib 123 than the first rib 121, the second rib 122, the slit 170, and the first groove 141. The guide 180 may be inclined or tapered in such a way that the area of ​​the second groove 142 increases from the second groove 142 in a second direction. Because the guide 180 is tapered, the connector 300 can be easily inserted into and separated from the cover 100 via the guide 180. The guide 180 may be a connecting guide, an insertion guide, an introduction guide, a removal guide, and / or a separating guide.

[0168] The width d2 of the second groove 142 can be greater than the width d1 of the first groove 141. For example, the area of ​​the second groove 142 can be greater than the area of ​​the first groove 141. The connector can be inserted into the second groove 142 first and then into the first groove 141. Therefore, the connector 300 can be easily inserted into the mating groove 140 of the cover 100.

[0169] The cover 100 may include a retaining groove 160. The retaining groove 160 of the cover 100 may be configured to engage with a retaining protrusion 334 of the connector 300. The retaining groove 160 may have a shape corresponding to the retaining protrusion 334. The retaining groove 160 may be configured to communicate with a mating groove 140. For example, the retaining groove 160 may be formed along with a recess in the second rib 122. The retaining groove 160 may also be included in the mating groove 140.

[0170] The cover 100 may include a slit 170. The slit 170 may be formed by cutting through a portion of the first cover extension 120. The slit 170 may allow a portion of the first cover extension 120 to elastically deform. For example, the slit 170 may be positioned between the second rib 122 and the mating groove 140, such that the second rib 122 can elastically deform relative to the mating groove 140. For example, as a force is applied to the second rib 122, the size of the second groove 242 of the mating groove 140 may change.

[0171] The cover 100 may include a second cover extension 130. The second cover extension 130 may extend from the cover panel 110. The second cover extension 130 may extend from a second side of the cover panel 110. For example, the second cover extension 130 may extend from a fourth edge 114 of the cover panel 110. For example, the second cover extension 130 may extend from the fourth edge 114 in a third direction C intersecting the first direction A and the second direction B. The second cover extension 130 may be arranged on the opposite side of the first cover extension 120 with reference to the cover panel 110. The second cover extension 130 may be configured to face the first cover extension 120.

[0172] The cover 100 may include an insertion protrusion 150. The insertion protrusion 150 may be formed in the second cover extension 130. The insertion protrusion 150 may protrude from the second cover extension 130. The insertion protrusion 150 may be inserted into a second insertion hole 2162 of the frame 210. For example, the first insertion protrusion 150 may be inserted into the second insertion hole 2162 in a fourth direction D opposite to the first direction A.

[0173] Figure 13 An example is shown of a cooking appliance according to an embodiment, in which the lid is in the first lid position. Figure 14 This is a cross-sectional view of a cooking apparatus according to one embodiment. Figure 15 This is a cross-sectional view of a cooking apparatus according to one embodiment. Figure 16 An example is shown of a cooking appliance according to one embodiment, in which the lid is in the second lid position. Figure 17 This is a cross-sectional view of a cooking apparatus according to one embodiment.

[0174] Figure 14 It is along Figure 13 A cross-sectional view taken from the A-A' line. Figure 15 It is along Figure 13 A cross-sectional view taken from the B-B' line. Figure 17 It is along Figure 15 A cross-sectional view taken from the C-C' line.

[0175] Reference Figures 13 to 17 The cover 100 is rotatable and / or movable between a position covering and / or closing the inlet 12 (first cover position P1) and a position opening the inlet 12 (second cover position P2). Furthermore, since the connector 300 is linked to the cover 100, the connector 300 is rotatable and / or movable between a first connector position P1' corresponding to the first cover position P1 and a second connector position P2' corresponding to the second cover position P2.

[0176] The cover 100 can rotate in conjunction with the connector 300. During engagement of the connector 300's engagement protrusion 333 with the cover 100's engagement groove 140, the cover 100 can be linked with the connector 300 to either close or open the suction port 12. During engagement of the connector 300's engagement protrusion 333 with the cover 100's engagement groove 140, the cover 100 can be configured to rotate together with the connector 300 as the connector 300's engagement protrusion 333 rotates about the connector 300's shaft portion 331. The cover 100's engagement groove 140, which engages with the connector 300's engagement protrusion 333, can be configured to rotate about the connector 300's shaft portion 331. The connector 300's shaft portion 331 can be configured to form a rotational axis for the cover 100. The shaft portion 331 can be referred to as a rotational axis.

[0177] Reference Figures 13 to 15 During the period when the cover 100 is in the first cover position P1 of the closed intake port 12, the cover 100 may be restricted from moving upward due to interference from the connector 300. For example, during the period when the cover 100 is in the closed intake port 12 position P1, the cover 100 may not be separated from the connector 300. At this time, the connector 300 may be in the first connector position P1'.

[0178] For example, during the period when the engaging protrusion 333 engages with the engaging groove 140 and the cover 100 is in position P1 of the closed intake port 12, the engaging protrusion 333 may be positioned above the second rib 122. Thus, even if the user attempts to lift the cover 100, the cover 100 may not detach from the connector 300 due to the interference between the second rib 122 and the engaging protrusion 333.

[0179] Furthermore, since the movement of the movable protrusion 262 is restricted and guided by the guide rib 218, the movable protrusion 262 cannot move further upward by means of the guide rib 218 provided on the upper side while the cover 100 is in the first cover position P1. Therefore, it is possible to prevent the cover 100 from moving upward from the first cover position P1.

[0180] Reference Figure 16 and Figure 17 During the period when the cover 100 is in the open intake port 12 position P2, the cover 100 can be detachably mounted from the connector 300 upwards. For example, during the period when the cover 100 is in the second cover position P2 of the open intake port 12, the cover 100 can be in a state that allows it to be detached from the connector 300. At this time, the connector 300 can be in the second connector position P2'.

[0181] For example, during the period when the engaging protrusion 333 engages with the engaging groove 140 and the cover 100 is in position P2 of the open intake port 12, the second groove portion 142 of the engaging groove 140 can be oriented downwards. Thus, when the user wants to lift the cover 100, the upward movement of the cover 100 can be unaffected by the connector 300 and at least one rib 121, 122 and / or 123. For example, when the user lifts the cover 100, the engaging groove 140 of the cover 100 moves upwards, and the engaging protrusion 333 of the connector 300 can disengage from the engaging groove 140 through the second groove portion 142 and the guide 180.

[0182] Figure 18 This is a perspective view of a cooking apparatus according to one embodiment. Figure 19 This is a perspective view of a cooking apparatus according to one embodiment.

[0183] Figure 18 An example is shown of a cooking appliance according to an embodiment, in which the mating groove of the lid is separated from the mating protrusion of the connector. Figure 19 An example is shown of a cooking appliance according to one embodiment, in which the insertion protrusion of the lid is separated from the frame.

[0184] Reference Figure 18 and Figure 19 An example will be described with respect to the separation of cover 100 from connector 300.

[0185] While the cover 100 is in the position of the open intake port 12, the cover 100 can be separated from the connector 300. The engagement groove 140 of the cover 100 can be separated from the engagement protrusion 333 of the connector 300 (see reference). Figure 18 For example, as the first cover extension 120 of the cover 100 moves upward, the engagement groove 140 of the cover 100 can separate from the engagement protrusion 333 of the connector 300. For example, the first cover extension 120 of the cover 100 can move upward when the size of the second groove 142 increases with the elastic deformation of the second rib 122. Then, the insertion protrusion 150 of the cover 100 can separate from the second insertion hole 2162 of the frame 120 (see reference). Figure 19 For example, with cover 100 in the fourth direction D (refer to...) Figure 10 The first direction A in the opposite direction (refer to) Figure 10 The insertion protrusion 150 can be separated from the second insertion hole 1262 when the insertion protrusion 150 is disengaged from the second insertion hole 2162. The second cover extension 130 of the cover 100 can be moved upward.

[0186] Figure 20 This is a schematic diagram of a cooking apparatus according to one embodiment. Figure 21 This is a schematic diagram of a cooking apparatus according to one embodiment.

[0187] Reference Figure 20 and Figure 21 The process of attaching cover 100 to connector 300 can be combined with Figures 17 to 19 The process described herein is performed in the reverse order. For example, after the insertion protrusion 150 of the cover 100 is inserted into the second insertion hole 1262, the engagement groove 140 of the cover 100 can engage with the engagement protrusion 333 of the connector 300.

[0188] For example, during the period when the connector 300 is in the second connector position P2', the cover 100 and the connector 300 can engage. The cover 100 can move downwards such that the engaging protrusion 333 is inserted into the engaging groove 140. As the cover 100 moves downwards, the first end 333a (e.g., the upper end) of the connector 300 can first be inserted into the second groove 142, which has a larger area than the first groove 141, and then into the first groove 141. During the period when the connector 300 is inserted into the engaging groove 140, the retaining protrusion 333 of the connector 300 can be inserted into the retaining groove 160.

[0189] Furthermore, the groove forming portion 124 may have a predetermined angle b1, and the fixing protrusion 334 may also have a predetermined angle a1. Additionally, the second end 333b (e.g., the lower end) of the engaging protrusion 333 may also have a predetermined angle a2. For example, the groove forming portion 124, the fixing protrusion 334, and the second end 333b of the engaging protrusion 333 may have predetermined angles a1, a2, and b1 based on the horizontal and / or vertical directions. For example, during the period when the connector 300 is in the second connector position P2' and the cover 100 is in the second cover position P2, the groove forming portion 124, the fixing protrusion 334, and the second end 333b of the engaging protrusion 333 may have predetermined angles a1, a2, and b1 based on the horizontal direction. Furthermore, for example, during the period when the connector 300 is in the first connector position P1' and the cover 100 is in the first cover position P1, the second end 333b of the groove forming portion 124, the fixing protrusion 334 and the engaging protrusion 333 can have predetermined angles a1, a2, b1 with the vertical direction as a reference.

[0190] However, the second end 333b of the groove forming portion 124, the fixing protrusion 334, and the connecting protrusion 333 may not have any angle, or only one of them may have an angle. For example, only the groove forming portion 124 may have a predetermined angle b1, or only the second end 333b of the connecting protrusion 333 may have a predetermined angle a2, or only the fixing protrusion 334 may have a predetermined angle a1.

[0191] Therefore, the second end 333b of the connecting protrusion 333 and the fixing protrusion 334 can be supported by the groove forming portion 124. After the connector 300 is inserted into the connecting groove 140 of the connecting portion 120, the fixing protrusion 334 is inserted into and fixed in the fixing groove 160, making it difficult for the connector 300 to detach from the connecting portion 120. For example, the predetermined angles a1, a2, and b1 of the groove forming portion 124, the fixing protrusion 334, and the second end 333b of the connecting protrusion can be 10 degrees or more.

[0192] Furthermore, the guide 180 may have a predetermined angle b2. For example, the guide 180 may have a predetermined angle b2 based on the horizontal and / or vertical directions. For example, during the period when the connector 300 is in the second connector position P2' and the cover 100 is in the second cover position P2, the guide 180 may have a predetermined angle b2 based on the horizontal direction. And, for example, during the period when the connector 300 is in the first connector position P1' and the cover 100 is in the first cover position P1, the guide 180 may have a predetermined angle b2 based on the vertical direction.

[0193] Figure 22 This is a schematic diagram of a cooking apparatus according to one embodiment. Figure 23 This is a schematic diagram of a cooking apparatus according to one embodiment. Figure 24 This is a schematic diagram of a cooking apparatus according to one embodiment. Figure 25 This is a schematic diagram of a cooking apparatus according to one embodiment. Figure 26 This is a schematic diagram of a cooking apparatus according to one embodiment. Figure 27 This is a schematic diagram of a cooking apparatus according to one embodiment.

[0194] Reference Figures 22 to 27 During the period when the connector 300 is in the first connector position P1', the cover 100 and the connector 300 can engage. The cover 100 can move downwards, causing the engaging protrusion 333 to insert into the engaging groove 140. Since the connector 300 is in the first connector position P1', the cover 100 can be slightly tilted and inserted into the second groove 142. For example, the cover 100 can be located between the first cover position P1 and the second cover position P2. At this time, the second groove 142 can be formed wider due to the inclined or tapered guide 180.

[0195] Reference Figure 23 and Figure 24 The tilt of the guide 180 can guide the coupling protrusion 333 into the second groove 142. During the insertion of the connector 300 into the second groove 142, the cover 100 and the connector 300 can be slightly tilted and inserted into the second groove 142. For example, the connector 300 can be located between the first connector position P1' and the second connector position P2'.

[0196] Reference Figures 25 to 27 After the engaging protrusion 333 is inserted into the second groove 142, the cover 100 can move downwards as the engaging protrusion 333 moves toward the first groove 141. During the insertion of the connector 300 into the engaging groove 140, the retaining protrusion 334 of the connector 300 can be inserted into the retaining groove 160.

[0197] The lid 100 can be easily attached to or detached from the connector 300. The lid 100 does not need to be directly connected to the drive unit 200, but can be connected to the drive unit 200 via the connector 300. When the lid 100 is detached or removed from the cooking appliance 1, it is not necessary to disassemble the cooking appliance 1 as a whole or the drive unit 200. Only the lid 100 can be disassembled or removed separately from the cooking appliance 1. Therefore, cleaning and / or maintenance of the lid 100 is easy. As a result, the ease of use of the cooking appliance 1 can be improved.

[0198] According to one aspect of this disclosure, since the cover can be easily separated, the filter can be introduced and removed through the suction port, thereby providing a cooking device capable of cleaning the filter.
