Meanwhile, the frame 210 is illustrated as a component of the driving device 200, but it is not limited thereto. The frame 210 may be provided as a separate component from the driving device 200.
The frame 210 may include position guide protrusions 217 and 219. The position guide protrusions 217 and 219 may guide the position of the lever 260. For example, the position guide protrusions 217 and 219 may guide the position of the lever 260 in a first cover position P1 in which the cover 100 closes the inlet 12, or may guide the position of the lever 260 in a second cover position P2 in which the cover 100 opens the inlet 12. Because the lever 260 operates in conjunction with the coupler 300 and the moving member 250, the position guide protrusions 217 and 219 may also guide the positions of the coupler 300 and the moving member 250.
The position guide protrusions 217 and 219 may be provided in plural. The plurality of position guide protrusions may include a first position guide protrusion 217 and a second position guide protrusion 219.
The first position guide protrusion 217 may guide the position of the lever 260 in the first cover position P1 in which the cover 100 closes the inlet 12. The first position guide protrusion 217 may contact the lever 260 to prevent the lever 260 from rotating further upward. For example, a lower surface of the first position guide protrusion 217 may contact an upper surface of the lever 260.
The second position guide protrusion 219 may guide the position of the lever 260 in the second cover position P2 in which the cover 100 opens the inlet 12. The second position guide protrusion 219 may contact the lever 260 to prevent the lever 260 from rotating further downward. For example, a side surface of the second position guide protrusion 219 may contact a lower surface of the lever 260.
The drive device 200 may include the motor 220. The motor 220 may generate a rotational force and/or power. The motor 220 may provide a 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 to the cam 230.
The driving device 200 may include the cam 230. The cam 230 may be connected to the motor 220. The cam 230 may receive a rotational force and/or power from the motor 220. The cam 230 may rotate in conjunction with the motor 220.
The cam 230 may include a cam coupling portion 232 coupled to the motor shaft 221 of the motor 220. For example, the cam coupling portion 232 may be disposed at the center of the cam 230.
The cam 230 may include a cam shaft 231 spaced from the cam coupling portion 232. As the cam 230 connected to the motor 220 rotates, the cam shaft 231 may rotate about the cam coupling portion 232. As the cam 230 connected to the motor 220 rotates, the cam shaft 231 may rotate about the motor shaft 221.
The cam 230 may include at least one cam protrusion 233 and/or 234. As the cam 230 rotates, the at least one cam protrusion 233 and/or 234 may be provided to be in contact with the switch 280 that is described below. 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.
The driving device 200 may include the connecting rod 240. The connecting rod 240 may be connected to the cam 230. The connecting rod 240 may be moved in conjunction with the cam 230. For example, the connecting rod 240 may be moved in a vertical direction (Z direction).
A first end 241 of the connecting rod 240 may be connected to the cam shaft 231. The first end 241 of the connecting rod 240 may rotate in conjunction with the cam shaft 231. The first end 241 of the connecting rod 240 may rotate together with the cam shaft 231. Therefore, the first end 241 of the connecting rod 240 may rotate about the motor shaft 221 of the motor 220. The first end 241 of the connecting rod 240 may be provided to pivot around the motor shaft 221 of the motor 220. The first end 241 of the connecting rod 240 may rotate approximately in a circle.
A second end 242 of the connecting rod 240 may be moved in the vertical direction by the rotation of the first end 241 of the connecting rod 240. The second end 242 of the connecting rod 240 may be moved along a rail formed in the frame 210. The second end 242 of the connecting rod 240 may perform a linear reciprocating motion. The second end 242 of the connecting rod 240 may be connected to a moving member 250.
The driving device 200 may include the moving member 250. The moving member 250 may be moved in one direction. For example, the moving member 250 may slide in the vertical direction.
The moving member 250 may include a pressing portion 251. The pressing portion 251 may extend in one direction to press the lever 260. For example, the pressing portion 251 may extend in a horizontal direction to press a contact protrusion 261 of the lever 260 positioned below the pressing portion 251. The pressing portion 251 may come into contact with the contact protrusion 261. The pressing portion 251 may be provided above the moving portion 252.
The pressing portion 251 may be provided in plural. For example, the plurality of pressing portions 251a and 251b may include a first pressing portion 251a and a second pressing portion 251b. The first pressing portion 251a may extend in the horizontal direction. The second pressing portion 251b may be rotatably coupled to the first pressing portion 251a. The second pressing portions 251b may be coupled to both sides of the first pressing portion 251a. However, the pressing portion 251 may be provided with only the first pressing portion 251a.
Based on operation of the motor 220, the pressing portion 251 of the moving member 250 may press the contact protrusion 261 of the lever 260. For example, in an initial stage in which the cover 100 is moved from the first cover position P1 to the second cover position P2, the first pressing portion 251a may press the contact protrusion 261, and thereafter, the second pressing portion 251b may press the contact protrusion 261. Since the second pressing portion 251b is rotatably coupled to the first pressing portion 251a, the second pressing portion 251b does not interfere with or obstruct the rotation of the lever 260 including the contact protrusion 261 (see FIGS. 20 and 21).
The moving member 250 may further include a moving portion 252. The moving portion 252 may be positioned below the pressing portion 251. The moving portion 252 may extend in the vertical direction. The moving portion 252 may slide in the vertical direction. The moving portion 252 may be a sliding portion.
The moving member 250 may be connected to the second end 242 of the connecting rod 240. The moving member 250 may be movable in the vertical direction in conjunction with the second end 242 of the connecting rod 240. The moving member 250 may be provided to perform a linear reciprocating motion together with the second end 242 of the connecting rod 240. The moving member 250 may press the lever 260 while moving in the vertical direction. The moving member 250 may be referred to as a slider 250, a moving panel 250, and/or a moving block 250.
The driving device 200 may convert rotary motion into linear reciprocating motion. For example, the motor 220, the cam 230, and the first end 241 of the connecting rod 240 may perform rotary motion. For example, the second end 242 of the connecting rod 240 and the moving member 250 may perform linear reciprocating motion.
The driving device 200 may include the lever 260. The lever 260 may be pressed by the moving member 250. The lever 260 may be rotated when pressed by the moving member 250. The lever 260 may extend in one direction. For example, the lever 260 may extend in the horizontal direction. One end of the lever 260 along the longitudinal direction may be provided to rotate about the other end of the lever 260.
The lever 260 may be coupled to the frame 210 at the outside of the frame 210. The lever 260 may be disposed on the opposite side of the coupler 300 with respect to the wall 2102a of the frame 210.
The lever 260 may provide a rotational force to the cover 100. The lever 260 may rotate the cover 100. The coupler 300 connecting the lever 260 and the cover 100 may transmit the rotational force of the lever 260 to the cover 100. The coupler 300 may be mounted on the lever 260. The lever 260 may be separably coupled to the coupler 300 to transmit the force to the coupler 300. The lever 260, the coupler 300, and the cover 100 may be provided to be rotated together. However, the lever 260 and the coupler 300 may be formed as a single part to transmit the rotational force to the cover 100 or receive the rotational force from the cover 100.
The lever 260 may guide the rotation and movement of the cover 100 and/or the coupler 300. The lever 260 may be referred to as a guide link 260.
The lever 260 may include an extension portion 264. The extension portion 264 may extend in one direction. For example, while the cover 100 is in the first cover position P1, the extension portion 264 may extend in a second direction B1 or B2. Further, while the cover 100 is in the second cover position P2, the extension portion 264 may extend in a third direction C.
The lever 260 may include the contact protrusion 261 provided to come into contact with the moving member 250. The contact protrusion 261 may extend and/or protrude from the extension portion 264. For example, the contact protrusion may protrude in a first direction A. As the moving member 250 moves downward (-Z direction), the contact protrusion 261 may be contacted and pressed by the moving member 250.
The lever 260 may include a lever coupling portion 263 couplable to the coupler 300. The lever coupling portion 263 may be referred to as a link coupling portion 263. The contact protrusion 261 of the lever 260 may be rotated about the lever coupling portion 263 by the pressing force of the moving member 250. The contact protrusion 261 of the lever 260 may be rotated approximately in an arc about the lever coupling portion 263. Accordingly, as the lever 260 is pressed and rotated by the moving member 250, the cover 100 may operate to open the inlet 12.
The lever 260 may include a moving protrusion 262 configured to move along a path 2180 formed by a guide rib 218. The moving protrusion 262 may extend and/or protrude from the extension portion 264. For example, the moving protrusion 262 may protrude in a direction D opposite to the contact protrusion 261. The moving protrusion 262 may be arranged on the inside of the guide rib 218.
The moving protrusion 262 may be in contact with the elastic member 270. Disposed below the moving protrusion 262 is the second end 272 of the elastic member 270, and based on the movement of the moving protrusion 262, an elastic force may be generated in the elastic member 270. In this case, the elastic force generated in the elastic member 270 may be a force that restores the lever 260 to the original position thereof. The moving protrusion 262 may fix and support the second end 272 of the elastic member 270. The moving protrusion 262 may be referred to as a support protrusion and/or a fixing protrusion.
The lever 260 may include a plurality of levers 260a and 260b. The plurality of 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 the extension portion 264, the contact protrusion 261, the lever coupling portion 263, and the moving protrusion 262.
In the drawing, the driving device 200 is illustrated as including two levers 260a and 260b, but it is not limited thereto. The number of levers 260 may correspond to the number of cover members described below.
The driving device 200 may include the elastic member 270. The elastic member 270 may be provided to elastically bias the cover 100 and/or the lever 260. The elastic member 270 may comprise a spring 270.
The elastic member 270 may be provided to elastically bias the lever 260 such that the lever 260 is rotated in a direction opposite to the direction in which the lever 260 is rotated by being pressed by the moving member 250. In addition, the moving member 250 and the elastic member 270 may not be constrained to each other. In addition, the cover 100 connected to the lever 260 through the coupler 300 may also be rotated in conjunction with the lever 260.
For example, in response to the cover 100 rotating in a first rotation direction to open the inlet 12, the coupler 300 and the lever 260 may also rotate, and the elastic member 270 may press the lever 260 and the cover 100 in a second rotation direction to close the inlet 12.
In other words, regardless of the movement and position of the moving member 250, the elastic member 270 may allow the cover 100 to rotate in a direction that covers and/or closes the inlet 12. As the moving member 250 moves upward (-Z direction), the lever 260 may not be pressed by the moving member 250. The lever 260 that is not pressed by the moving member 250 may rotate in a direction in which the cover 100 closes the inlet 12 by the elastic restoring force of the elastic member 270. Accordingly, as the lever 260 rotates while being elastically biased by the elastic member 270, the cover 100 may operate to close the inlet 12.
The elastic member 270 may be configured to surround a wall 2163 of the frame 210 forming the first insertion hole 2161. The elastic member 270 may include a first end 271 and a second end 272. A movement of the first end 271 of the elastic member 270 may be restricted by a support protrusion 213. For example, the first end 271 of the elastic member 270 may be in contact with a lower surface of the support protrusion 213. The second end 272 of the elastic member 270 may be in contact with the moving protrusion 262 of the lever 260. For example, as the lever 260 rotates when the second end 272 of the elastic member 270 comes into contact with the lower surface of the moving protrusion 262 of the lever 260, the cover 100 may also rotate, and an elastic force may be generated in the elastic member 270. Based on the rotation of the lever 260, the elastic member 270 may generate a force that allows the lever 260 and the cover 100 to return to the positions before the rotation.
In other words, the moving member 250 may not press the cover 100 in the direction (upward) in which the cover 100 closes the inlet 12, and the elastic member 270 may press the lever in the direction (upward) in which the cover 100 closes the inlet 12. In addition, when a user presses the cover 100 downward to open the inlet 12, the cover 100, the lever 260, the coupler 300, and the elastic member 270 may rotate without the movement of the moving member 250. In addition, the elastic member 270 may press the lever 260 in the direction in which the cover 100 closes the inlet 12.
Accordingly, even when the user's body is caught between a first cover member 100a and a second cover member 100b, the user may pull the body out by pressing the first cover member 100a and the second cover member 100b downward to increase a gap between the first cover member 100a and the second cover member 100b. After pulling the body out, the first cover member 100a and the second cover member 100b may return to the first cover position P1 by the elastic member 270. The cooking apparatus may prevent the user's body from being injured by being caught between the first cover member 100a and the second cover member 100b.
In the drawing, the driving device 200 is illustrated as including two elastic members 270a and 270b, but the present disclosure is not limited thereto. The number of elastic members 270 may be the same as the number of cover members described below.
Additionally, the plurality of elastic members 270a and 270b are illustrated as including first ends 271a and 271b and second ends 272a and 272b, respectively, but are not limited thereto.
The driving device 200 may include the switch 280. The switch 280 may be positioned adjacent to the cam 230. The switch 280 may be configured to detect a rotational position of the cam 230. The switch 280 may be provided to be in contact with the 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 being in contact with the at least one cam protrusion 233 and/or 234 of the cam 230. The cooking apparatus may determine the position of the cover 100 based on whether the switch 280 is turned on/off. For example, a controller of the cooking apparatus may determine whether the cover 100 opens the inlet 12 or closes the inlet 12. In the drawing, two switches 280 are illustrated, but the present disclosure is not limited thereto. The switch 280 may be provided as one or as three or more.
The cooking apparatus 1 may include the coupler 300. The coupler 300 may connect the driving device 200 and the cover 100. The coupler 300 may be configured to transmit power of the driving device 200 to the cover 100. The coupler 300 may be rotated by power generated by the driving device 200. The cover 100 coupled to the coupler 300 may be rotated together with the coupler 300. As a result, the cover 100 may operate to close or open the inlet 12.
One side of the coupler 300 may be coupled to the driving device 200, and the other side of the coupler 300 may be coupled to the cover 100.
The coupler 300 may include a shaft portion 331 insertable into the first insertion hole 2161 of the frame 210. For example, the shaft portion 331 may be insertable into the first insertion hole 2161 in a first direction (A in FIGS. 8 and 10). The shaft portion 331 may be inserted into the first insertion hole 2161 and connected to the lever 260. For example, an end 3311 of the shaft portion 331 may be separably connected to the lever coupling portion 263 of the lever 260.
The coupler 300 may include a coupling protrusion 333. The coupling protrusion 333 of the coupler 300 may be separably coupled to a coupling groove 140 of the cover 100 to be described below. The coupling protrusion 333 and the coupling groove 140 may have shapes corresponding to each other. The coupling protrusion 333 may extend and/or protrude from the shaft portion 331. The coupling protrusion 333 may extend and protrude in a left and right direction (e.g., Y, and -Y) from the shaft portion 331. As will be described below, when the coupler 300 includes a shield portion 332, the coupling protrusion 333 may extend and protrude in the left and right direction (e.g., Y, and -Y) from the shield portion 332. For example, the coupling protrusion 333 may extend from the shaft portion 331 in a second direction (B1 or B2 in FIG. 8) intersecting the first direction A. For example, as for a coupler 300a, the coupling protrusion 333 may extend from the shaft portion 331 in the second direction B1 intersecting the first direction A. For example, as for a coupler 300b, the coupling protrusion 333 may extend from the shaft portion 331 in the second direction B2 intersecting the first direction A.
The coupling protrusion 333 may be provided to be rotatable around the shaft portion 331 inserted into the first insertion hole 2161. The coupling protrusion 333 may be rotated approximately in an arc about the shaft portion 331 inserted into the first insertion hole 2161.
The coupler 300 may include a fixing protrusion 334. The fixing protrusion 334 may allow the coupling protrusion 333 to be fixed to the inside of the coupling groove 140. The fixing protrusion 334 may be formed on the coupling protrusion 333. For example, the fixing protrusion 334 may protrude from one end of the coupling protrusion 333. The fixing protrusion 334 of the coupler 300 may be provided to be locked to a fixing groove 160 of the cover 100. The fixing protrusion 334 of the coupler 300 may be provided to be engaged with the fixing groove 160 of the cover 100. While the fixing protrusion 334 of the coupler 300 and the fixing groove 160 of the cover 100 are engaged, the cover 100 may not be easily separated from the coupler 300. While the fixing protrusion 334 of the coupler 300 and the fixing groove 160 of the cover 100 are engaged, the cover 100 may not be dislocated from the coupler 300. While the fixing protrusion 334 of the coupler 300 and the fixing groove 160 of the cover 100 are engaged, the cover 100 may not shake during the operation of opening or closing the inlet 12 and thus the cover 100 may be stably operated.
A coupling portion 120 of the cover 100 may include a groove forming portion 124. For example, the groove forming portion 124 may be formed in a second rib portion 122 to form the fixing groove 160. The groove forming portion 124 may include a step.
The coupler 300 may include the shield portion 332. The shield portion 332 may extend from the shaft portion 331. For example, the shield portion 332 may be disposed between the shaft portion 331 and the coupling protrusion 333. The shield portion 332 may be provided to cover the first insertion hole 2161. The shield portion 332 may be larger than the first insertion hole 2161. The shield portion 332 may have a larger size than the first insertion hole 2161. For example, a diameter of the shield portion 332 may be greater than a diameter of the first insertion hole 2161. The first insertion hole 2161 into which the coupler 300 is inserted may be sealed. As a result, air flowing in the flow path 210f may be prevented from leaking out through the first insertion hole 2161. Air guided by the frame 210 may be prevented from leaking out through the first insertion hole 2161. As a result, contaminants contained in the air may be prevented from penetrating into the internal space 13c of the case 13, various components of the driving device 200, etc.
The coupler 300 may include a plurality of couplers 300a and 300b. The plurality of couplers 300a and 300b may include a first coupler 300a and a second coupler 300b. Each of the first coupler 300a and the second coupler 300b may include the shaft portion 331, the shield portion 332, the coupling protrusion 333, and the fixing protrusion 334.
In the drawing, the cooking apparatus 1 is illustrated as including two couplers 300a and 300b, but is not limited thereto. The number of couplers 300 may be equal to the number of cover members described below.
The cooking apparatus 1 may include the cover 100. The cover 100 may include at least one cover member 100a and/or 100b. The cover members 100a and 100b may extend in one direction. i.e. they are elongate. For example, the cover members 100a and 100b may extend in the horizontal direction. For example, the cover members 100a and 100b may extend in a front and rear direction.
The cover 100 may include a first cover member 100a and a second cover member 100b. For example, the first cover member 100a and the second cover member 100b may be arranged in the Y direction (e.g., left-right direction). The first cover member 100a may cover a portion of the inlet 12, and the second cover member 100b may cover another portion of the inlet 12. In addition, the first cover member 100a may open and close a portion of the inlet 12, and the second cover member 100b may open and close another portion of the inlet 12.
In the drawing, it is illustrated that the cover 100 includes the first cover member 100a and the second cover member 100b, and the first cover member 100a and the second cover member 100b are arranged approximately along the horizontal direction (Y direction), but the present disclosure is not limited thereto. For example, the cover 100 may include a single cover member, and in this case, one cover member may have a size corresponding to the inlet 12. For example, the first cover member 100a and the second cover member 100b may be arranged approximately along the front and rear direction (X direction). For example, the cover 100 may include three or more cover members. The present disclosure may include cover members provided in various numbers, shapes, and/or arrangements. Hereinafter for the sake of convenience of description, an example in which the cover 100 includes the first cover member 100a and the second cover member 100b will be described.
In the drawing, reference signs for a configuration of the first cover member 100a and/or a configuration corresponding to the first cover member 100a may be indicated with "a". In the drawing, reference signs for a configuration of the second cover member 100b and/or a configuration corresponding to the second cover member 100b may be indicated with "b". For example, a lever 260a, the coupler 300a, an elastic member 270a, a first insertion hole 2161a, a second insertion hole 2162a, and the like may be provided to correspond to the first cover member 100a. For example, a lever 260b, a coupler 300b, an elastic member 270b, a first insertion hole 2161b, a second insertion hole 2162b, and the like may be provided to correspond to the second cover member 100b.
The first cover member 100a and the second cover member 100b may be provided symmetrically. The first cover member 100a and the second cover member 100b may be provided symmetrically with respect to a vertical center line V of the inlet 12. The first cover member 100a and the second cover member 100b may have substantially the same shape.
Hereinafter a description of one of the first cover member 100a and the second cover member 100b may be applied to a description of the other one of the first cover member 100a and the second cover member 100b. Hereinafter the description of the cover 100 may be applied to both the first cover member 100a and the second cover member 100b. Hereinafter for the sake of convenience of description, the description of the cover 100 may be replaced with the description of each cover member.
The cover 100 may be separably connected to the coupler 300. The coupler 300 may be inserted into the cover 100 or withdrawn from the cover 100. The cover 100 may be linked with the coupler 300 to close the inlet 12 or open the inlet 12. The cover 100 may be rotated together with the coupler 300. As the coupler 300 is rotated by the driving device 200, the cover 100 connected to the coupler 300 may also be rotated.
The cover 100 may include a cover panel 110. The cover panel 110 may be provided to correspond to the inlet 12. The cover panel 110 may have a shape that extends to cover the inlet 12. For example, the cover panel 110 may extend in the front and rear direction.
For example, the cover panel 110 may have a substantially plate 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 provided as long sides. For example, the third edge portion 113 and the fourth edge portion 114 may be provided as short sides. For example, the third edge portion 113 may be provided on a side adjacent to the lever 260 of the driving device 200. For example, the fourth edge portion 114 may be provided on an opposite side of the third edge portion 113. For example, the cover panel 110 may have a shape that is long in the front and rear direction (X direction) and short in the horizontal direction (Y direction). However, the present disclosure is not limited to the above-described examples, and the cover panel 110 may have various shapes.
The cover 100 may include a first cover extension portion 120. The first cover extension portion 120 may extend from the cover panel 110. The first cover extension portion 120 may extend from a first side of the cover panel 110. For example, the first cover extension portion 120 may extend from the third edge portion 113 of the cover panel 110. For example, the first cover extension portion 120 may extend from the third edge portion 113 to the third direction C intersecting the first direction A and the second direction B. For example, the first cover extension portion 120 may extend downward from one end along the longitudinal direction of the cover panel 110.
The cover 100 may include the coupling portion 120. For example, the first cover extension portion 120 may be the coupling portion 120. The coupling portion 120 may allow the coupler 300 to be coupled to the cover 100. The coupling portion 120 may include the coupling groove 140. For example, the coupling groove 140 may be formed in the first cover extension portion 120. The coupler 300 may be coupled and/or inserted into the coupling groove 140. The coupling groove 140 of the cover 100 may be separably coupled to the coupling protrusion 333 of the coupler 300. The coupling groove 140 of the cover 100 may have a shape corresponding to the coupling protrusion 333 of the coupler 300. For example, the coupling groove 140 of the cover 100 may extend along an extension direction of the third edge portion 113 of the cover panel 110.
It is described that the cover 100 is provided with the coupling portion 120 including the coupling groove 140, and the coupler 300 is inserted into the coupling groove 120. However, the coupler 300 may include the coupling groove, and the coupling portion protruding to be inserted into the coupler 300 may be provided in the cover 100.
The first cover extension portion 120 may include a first rib portion 121 adjacent to the cover panel 110. The first cover extension portion 120 may include a second rib portion 122 spaced apart from the first rib portion 121. The second rib portion 122 may be spaced apart from the first rib portion 121 with the coupling groove 140 interposed therebetween. The second rib portion 122 may be spaced apart from the first rib portion 121 in the third direction C. The first cover extension portion 120 may include a third rib portion 123 connecting the first rib portion 121 and the second rib portion 122. The first cover extension portion 120 may be referred to as the coupling portion 120 forming the coupling groove 140.
The coupling groove 140 may include a first groove portion 141 provided to be surrounded by the first rib portion 121, the second rib portion 122, and the third rib portion 123. The coupling groove 140 may include a second groove portion 142 provided to be open on the opposite side of the first groove portion 141. For example, the second groove portion 142 may correspond to a portion of the coupling groove 140 that is not surrounded by the first rib portion 121, the second rib portion 122, and the third rib portion 123. An area of the second groove portion 142 may increase in the second direction. For example, the coupling groove 140 may include an approximately U-shape.
The cover 100 may include a guide 180. The coupling portion 120 may include the guide 180. The guide 180 may guide the coupling of the coupler 300 to the coupling portion 120. For example, the guide 180 may guide insertion of the coupler 300 into the coupling groove 140. The guide 180 may be provided adjacent to the second groove portion 142. The guide 180 may be arranged farther from the third rib portion 123 than from the first rib portion 121, the second rib portion 122, a slit portion 170, and the first groove portion 141. The guide 180 may be inclined to allow an area of the second groove portion 142 to increase from the second groove portion 142 to the second direction. Because the guide 180 is formed to be tapered, the coupler 300 may be easily inserted into and separated from the cover 100 through the guide 180. The guide 180 may be a coupling guide, an insertion guide, an inlet guide, a withdrawal guide, and/or a separation guide.
A width d2 of the second groove portion 142 may be greater than a width d1 of the first groove portion 141. For example, the area of the second groove portion 142 may be greater than an area of the first groove portion 141. The coupler may be first inserted into the second groove portion 142 and then inserted into the first groove portion 141. Accordingly, the coupler 300 may be easily inserted into the coupling groove 140 of the cover 100.
The cover 100 may include the fixing groove 160. The fixing groove 160 of the cover 100 may be provided to allow the fixing protrusion 334 of the coupler 300 to be locked thereto. The fixing groove 160 may have a shape corresponding to the fixing protrusion 334. The fixing groove 160 may be provided to communicate with the coupling groove 140. For example, the fixing groove 160 may be formed as the second rib portion 122 is recessed. The fixing groove 160 may also be included in the coupling groove 140.
The cover 100 may include the slit portion 170. The slit portion 170 may be formed by a portion of the first cover extension portion 120 that has been cut out. The slit portion 170 may allow a portion of the first cover extension portion 120 to be elastically deformed. For example, the slit portion 170 may be provided between the second rib portion 122 and the coupling groove 140 to allow the second rib portion 122 to be elastically deformable relative to the coupling groove 140. For example, as a force is applied to the second rib portion 122, a size of the second groove portion 242 of the coupling groove 140 may be changed.
The cover 100 may include a second cover extension portion 130. The second cover extension portion 130 may extend from the cover panel 110. The second cover extension portion 130 may extend from a second side of the cover panel 110. For example, the second cover extension portion 130 may extend from the fourth edge portion 114 of the cover panel 110. For example, the second cover extension portion 130 may extend from the fourth edge portion 114 to the third direction C intersecting the first direction A and the second direction B. The second cover extension portion 130 may be arranged on an opposite side of the first cover extension portion 120 with respect to the cover panel 110. The second cover extension portion 130 may be arranged to face the first cover extension portion 120.
The cover 100 may include an insertion protrusion 150. The insertion protrusion 150 may be formed on the second cover extension portion 130. The insertion protrusion 150 may protrude from the second cover extension portion 130. The insertion protrusion 150 may be inserted into the second insertion hole 2162 of the frame 210. For example, the insertion protrusion 150 may be inserted into the second insertion hole 2162 in a fourth direction D that is opposite to the first direction A.
FIG. 13 illustrates an example of a state in which a cover is in a first cover position in the cooking apparatus according to one embodiment. FIG. 14 illustrates an example of a state in which the cover is in a second cover position in the cooking apparatus according to one embodiment.
Referring to FIGS. 13 and 14, the cover 100 may be movable between a position (first cover position P1 that covers and/or closes the inlet 12 and a position (second cover position P2 that opens the inlet 12.
The cover 100 may rotate in conjunction with the coupler 300. While the coupling protrusion 333 of the coupler 300 is coupled to the coupling groove 140 of the cover 100, the cover 100 may close the inlet 12 or open the inlet 12 in conjunction with the coupler 300. The cover 100 may be provided to rotate together with the coupler 300 as the coupling protrusion 333 of the coupler 300 rotates about the shaft portion 331 of the coupler 300 while the coupling protrusion 333 of the coupler 300 is coupled to the coupling groove 140 of the cover 100. The coupling groove 140 of the cover 100 coupled to the coupling protrusion 333 of the coupler 300 may be provided to rotate about the shaft portion 331 of the coupler 300. The shaft portion 331 of the coupler 300 may be configured to form a rotating axis of the cover 100. The shaft portion 331 may be referred to as a rotating shaft.
While the cover 100 is in the first cover position P1 that closes the inlet 12, the cover 100 may be restricted from moving upward due to interference by the coupler 300. For example, while the cover 100 is in the position P1 that closes the inlet 12, the cover 100 may not be separated from the coupler 300.
For example, while the coupling protrusion 333 and the coupling groove 140 are coupled and the cover 100 is in the position P1 in which the cover 100 closes the inlet 12, the coupling protrusion 333 may be positioned upward of the second rib portion 122. Accordingly, even when a user attempts to lift the cover 100, the cover 100 may not be separated from the coupler 300 as the second rib portion 122 and the coupling protrusion 333 interfere with each other.
In addition, the movement of the moving protrusion 262 is restricted and guided by the guide rib 219, and thus while the cover 100 is in the first cover position P1, the moving protrusion 262 may not move further upward by the guide rib 219 provided at the upper side. Accordingly, the cover 100 may be prevented from moving upward in the first cover position P1.
While the cover 100 is in a position P2 that opens the inlet 12, the cover 100 may be provided to be separable upwardly from the coupler 300. For example, while the cover 100 is in the second cover position P2 that opens the inlet 12, the cover 100 may be separable from the coupler 300.
For example, while the coupling protrusion 333 is coupled to the coupling groove 140 and the cover 100 is in a position P2 in which the cover 100 opens the inlet 12, the second groove portion 142 of the coupling groove 140 may face downward. Accordingly, when a user attempts to lift the cover 100, the upward movement of the cover 100 may not be interfered by the coupler 300 and the at least one rib portion 121, 122 and/or 123. For example, when a user lifts the cover 100, the coupling groove 140 of the cover 100 may move upward, and the coupling protrusion 333 of the coupler 300 may be disengaged from the coupling groove 140 through the second groove portion 142 and the guide 180.
While the cover 100 is moved from the first cover position P1 to the second cover position P2, the pressing portion 251 of the moving member 250 may press the contact protrusion 261 of the lever 260. For example, when the rotation angle of the cover 100 is small, the first pressing portion 251a may press the contact protrusion 261, and as the rotation angle of the cover 100 increases, the second pressing portion 251b may press the contact protrusion 261. However, when the pressing portion 251 is provided with only the first pressing portion 251a, rounding portions 251aa provided at both ends of the first pressing portion 251a may press the contact protrusion 261 as the rotation angle of the cover 100 increases.
FIG. 15 is a front view of the cooking apparatus according to one embodiment. FIG. 16 is an enlarged view of the cooking apparatus according to one embodiment. FIG. 17 is an enlarged view of the cooking apparatus according to one embodiment. FIG. 18 is an enlarged view of the cooking apparatus according to one embodiment. FIG. 19 is an enlarged view of the cooking apparatus according to one embodiment. FIG. 20 is an enlarged view of the cooking apparatus according to one embodiment. FIG. 21 is an enlarged view of the cooking apparatus according to one embodiment.
FIGS. 15 to 17 illustrate a state before the first cover member 100a and the second cover member 100b are rotated. FIG. 17 illustrates the cooking apparatus in which the slider 250 is omitted for description. FIG. 18 illustrates a state in which only the first cover member 100a is rotated. For example, FIG. 18 illustrates that the first cover member 100a is rotated by about 5 degrees. FIGS. 19 to 21 illustrate a state in which the first cover member 100a and the second cover member 100b are rotated. For example, FIG. 19 illustrates a state in which the first cover member 100a is rotated about 15 degrees and the second cover member 100b is rotated about 5 degrees, FIG. 20 illustrates a state in which the first cover member 100a and the second cover member 100b are rotated about 50 degrees, and FIG. 21 illustrates a state in which the first cover member 100a and the second cover member 100b are rotated about 80 degrees.
However, the rotation angles of the first cover member 100a and the second cover member 100b shown in FIGS. 16 to 21 are only examples, and the values of the rotation angles shown in FIGS. 16 to 21 may vary depending on the vertical lengths of the first cover member 100a and the second cover member 100b. For example, when the vertical lengths of the first cover member 100a and the second cover member 100b increase, the angles shown in FIGS. 16 to 20 may also become larger.
An extension portion 264a of the first lever 260a may be referred to as a first extension portion 264a, and an extension portion 264b of the second lever 260b may be referred to as a second extension portion 264b. A contact protrusion 261a of the first lever 260a may be referred to as a first contact protrusion 261a, and a contact protrusion 261b of the second lever 260b may be referred to as a second contact protrusion 261b. A moving protrusion 262a of the first lever 260a may be referred to as a first moving protrusion 262a, and a moving protrusion 262b of the second lever 260b may be referred to as a second moving protrusion 262b.
Referring to FIGS. 16 and 17, the first lever 260a and the second lever 260b may have different widths. A width (L1 of the first extension portion 264a along one direction and a width (L2 of the second extension portion 264b along the one direction may be different. For example, in the first cover position P1 of the cover 100, the length (L1 of the first extension portion 264a along the vertical direction and the length (L2 of the second extension portion 264b along the vertical direction may be different. For example, in the first cover position P1 of the cover 100, the length (L1 of the first extension portion 264a along the vertical direction may be smaller than the length (L2 of the second extension portion 264b along the vertical direction. In other words, in the first cover position P1 of the cover 100, the length (L2 of the second extension portion 264b along the vertical direction may be greater than the length (L1 of the first extension portion 264a along the vertical direction. In addition, in the second cover position P2 of the cover 100, the length (L2 of the second extension portion 264b along the horizontal direction may be greater than the length (L1 of the first extension portion 264a along the horizontal direction.
While the cover 100 is in the first cover position P1, the first contact protrusion 261a may be positioned upward of (above) the second contact protrusion 261b. While the cover 100 is in the first cover position P1, the second contact protrusion 261b may be positioned downward of (below) the first contact protrusion 261a. For example, the second contact protrusion 261b may be provided at a position offset to a lower side of the second lever 260b. While the cover 100 is in the first cover position P1, a center C1 of the first contact protrusion 261a may be positioned upward of a center C2 of the second contact protrusion 261b. While the cover 100 is in the first cover position P1, the center C2 of the second contact protrusion 261b may be positioned downward of the center C1 of the first contact protrusion 261a.
The pressing portion 251 includes a first pressing portion 251a, and the first pressing portion 251a may include a rounded portion 251aa. The first pressing portion 251a may extend in one direction. For example, the first pressing portion 251a may extend in the Y direction, i.e. is elongate in the Y direction. The rounded portions 251aa may be provided at both ends along the extension direction and/or the longitudinal direction of the first pressing portion 251a. The rounded portions 251aa may be formed by rounding the lower surface and/or both side surfaces of the first pressing portion. The rounded portion 251aa may be formed adjacent to a rotation coupling portion 251ab.
The first pressing portion 251a may include the rotation coupling portion 251ab. The rotation coupling portion 251ab may be formed at both ends along the length direction of the first pressing portion 251a. The second pressing portion 251b may be rotatably coupled to the rotation coupling portion 251ab. The second pressing portion 251b may be rotatably coupled to the first pressing portion 251a to prevent the pressing portion 251 from obstructing or interfering with the rotation of the contact protrusion 261 as the cover 100 and the contact protrusion 261 rotate.
However, the pressing portion 251 may be provided only with the first pressing portion 251a, and the first pressing portion 251a may not include the rotation coupling portion 251ab. When the pressing portion 251 is provided with only the first pressing portion 251a, the rounded portions 251aa provided at both ends of the first pressing portion 251a may press the contact protrusion 261 in response to the increasing rotation angle of the cover 100 and the contact protrusion 261, and the contact protrusions 261 may rotate over the rounded portions 251aa. As the contact protrusions 261 are pressed by the rounded portions 251aa, the cover 100 may rotate.
Referring to FIG. 18, in response to the motor 220 being driven, one cover member 100a or 100b of the plurality of cover members 100a and 100b may rotate earlier than the other cover member 100a or 100b. The plurality of cover members 100a and 100b may be sequentially rotated. For example, in response to the motor 220 being driven, the first cover member 100a may rotate earlier than the second cover member 100b. For example, the first cover member 100a may rotate at least 5 degrees earlier than the second cover member 100b.
In response to the motor 220, the slider 250 may be moved downward. Since the first contact protrusion 261a is located upward of the second contact protrusion 261b, the pressing portion 251 of the slider 250 may press the first contact protrusion 261a downward before the second contact protrusion 261b. In this case, the pressing portion 251 may be in a state of not pressing the second contact protrusion 261b. For example, the first pressing portion 251a may press the first contact protrusion 261a and may not press the second contact protrusion 261b. As the first contact protrusion 261a is pressed, the first cover member 100a coupled to the first lever 260a and the first coupler 300a may rotate in a direction that opens the inlet 12. Based on the first cover member 100a being rotated, a portion of the inlet 12 may be opened.
Since the first cover member 100a and the second cover member 100b do not rotate simultaneously, the first cover member 100a and the second cover member 100b may be prevented from colliding and/or interfering with each other due to the rotation radii thereof. Since collision and/or interference between the first cover member 100a and the second cover member 100b may be prevented, the gap between the first cover member 100a and the second cover member 100b in the first cover position P1 of the cover may be minimized. Since the gap between the first cover member 100a and the second cover member 100b in the first cover position P1 of the cover is minimized, the aesthetics of the cooking apparatus may be improved.
Referring to FIG. 19, in response to the motor 220 being driven, the slider 250 may be moved downward. The pressing portion 251 may press the first contact protrusion 261a and the second contact protrusion 261b downward. As the first contact protrusion 261a and the second contact protrusion 261b are pressed, the first cover member 100a coupled to the first lever 260a and the first coupler 300a and the second cover member 100b coupled to the second lever 260b and the second coupler 300b may be rotated in a direction that opens the inlet 12. In this case, the first cover member 100a may be in a more rotated state than the second cover member 100b. For example, the first pressing portion 251a may simultaneously press the first contact protrusion 261a and the second contact protrusion 261b.
Referring to FIGS. 20 and 21, in response to the motor 220 being driven, the slider 250 may be moved downward, and thus the pressing portion 251 may press the first contact protrusion 261a and the second contact protrusion 261b downward. As the first contact protrusion 261a and the second contact protrusion 261b are pressed, the first cover member 100a and the second cover member 100b may be rotated to completely open the inlet 12. As the rotation angles of the first cover member 100a and the second cover member 100b increase, the second pressing portion 251b may press the first contact protrusion 261a and the second contact protrusion 261b (see FIG. 21).
In FIGS. 15 to 21, it has been described that based on the rotation of the motor 220, the first cover member 100a rotates first, followed by the rotation of the second cover member 100b. However, it is also possible that the second cover member 100b rotates first, followed by the rotation of the first cover member 100a. In addition, it is also possible for the user to press the plurality of cover members 100a and 100b to open the inlet 12 without the motor 220 being rotated.
FIG. 22 is a schematic view of the cooking apparatus according to one embodiment. FIG. 23 is a schematic view of the cooking apparatus according to one embodiment.
Referring to FIG. 22, the cover 100 may include a first cover member 100a and a second cover member 100b. The first cover member 100a and the second cover member 100b may be arranged in a horizontal direction to open and close the inlet 12.
The first cover member 100a may include an inclined portion 100aa. The inclined portion 100aa of the first cover member 100a may be referred to as a first inclined portion 100aa. For example, the first inclined portion 100aa may protrude toward the second cover member 100b as being directed downward. The first inclined portion 100aa may be provided on a side opposite to the rotational axis of the first cover member 100a. For example, the rotation axis of the first cover member 100a may be positioned at one end along the -Y direction, and the first inclined portion 100aa may be positioned at one end along the +Y direction.
The second cover member 100b may include an inclined portion 100ba. The inclined portion 100ba of the second cover member 100b may be referred to as a second inclined portion 100ba. For example, the second inclined portion 100ba may protrude toward the first cover member 100a as being directed upward. The second inclined portion 100ba may be provided on a side opposite to the rotation axis of the second cover member 100b. For example, the rotation axis of the second cover member 100b may be positioned at one end along the +Y direction, and the second inclined portion 100ba may be positioned at one end along the -Y direction.
The first inclined portion 100aa and the second inclined portion 100ba may correspond to each other. The directions in which the first inclined portion 100aa and the second inclined portion 100ba are inclined are not limited to the above-described example. For example, the first inclined portion 100aa may protrude toward the second cover member 100b as being directed upward, or the second inclined portion 100ba may protrude toward the first cover member 100a as being directed downward.
Based on the motor 220 being rotated, the first cover member 100a and the second cover member 100b may be rotated. For example, the first cover member 100a and the second cover member 100b may simultaneously rotate. Since the first inclined portion 100aa and the second inclined portion 100ba are inclined in correspondence with each other, even when the first cover member 100a and the second cover member 100b simultaneously rotate, the first cover member 100a and the second cover member 100b may not collide and/or interfere with each other. Since the first cover member 100a and the second cover member 100b do not collide and/or interfere with each other, the gap between the first cover member 100a and the second cover member 100b may be minimized, and the aesthetics of the cooking apparatus may be improved.
FIG. 23 is a schematic view of the cooking apparatus according to one embodiment.
Referring to FIG. 23, the cover 100 may include a first cover member 100a and a second cover member 100b. The first cover member 100a and the second cover member 100b may be arranged in a horizontal direction to open and close the inlet 12.
The first cover member 100a may include a body 101a and a protrusion 102a. The body 101a and the protrusion 102a of the first cover member 100a may be referred to as a first body 101a and a first protrusion 102a. The first body 101a may cover most of the area of the inlet 12 covered by the first cover member 100a. The first protrusion 102a may protrude from the first body 101a toward the second cover member 100b. The first protrusion 102a may be arranged below a second protrusion 102b.
The second cover member 100b may include a body 101b and a protrusion 102b. The body and the protrusion 102b of the second cover member 100b may be referred to as a second body 102a and a second protrusion 102b. The second body 102a may cover most of the area of the inlet 12 covered by the second cover member 100b. The second protrusion 102b may protrude from the second body 102a toward the first cover member 100a. The second protrusion 102b may be arranged above the first protrusion 102a.
The first body 101a may be larger than the first protrusion 102a. For example, the first protrusion 102a may be provided in a small size to prevent collision and/or interference with the second protrusion 102b while the first cover member 100a and the second cover member 100b are rotating. The second body 101b may be larger than the second protrusion 102b. For example, the second protrusion 102b may be provided in a small size to prevent collision and/or interference with the first protrusion 102a while the first cover member 100a and the second cover member 100b are rotating.
The first protrusion 102a and the second protrusion 102b may correspond to each other.
Based on the motor 220 being rotated, the first cover member 100a and the second cover member 100b may be rotated. For example, the first cover member 100a and the second cover member 100b may simultaneously rotate. Since the first protrusion 102a and the second protrusion 102b correspond to each other, even when the first cover member 100a and the second cover member 100b simultaneously rotate, the first cover member 100a and the second cover member 100b may not collide and/or interfere with each other. Since collision and/or interference between the first cover member 100a and the second cover member 100b does not occur, the gap between the first cover member 100a and the second cover member 100b may be minimized, and the aesthetics of the cooking apparatus may be improved.
