In other words, the rotation opening guide 340 may rotate in the first direction in response to the first opening link 320 rotating in the first direction. The rotation opening guide 340 may rotate with the opening shaft coupling portion 343 as the center of rotation. When the rotation opening guide 340 rotates in the first direction, the second opening limiting protrusion 346 may press a switching protrusion 371 of the switch 370. As a result, the switch 370 may reset the opening drive motor 310 to an initial position. In addition, the second opening limiting protrusion 346 may contact the other end of the stopper 380.
[0092] According to an embodiment of the present disclosure, the rotation range of the rotation opening guide 340 in the first direction may be doubly limited. In response to the second opening limiting protrusion 346 of the rotation opening guide 340 pressing the switching protrusion 371, an operation of the opening drive motor 310 may be stopped. In addition, in response to the second opening limiting protrusion 346 pressing the switching protrusion 371, a reference position of the opening drive shaft 311 may be reset. When the rotation opening guide 340 rotates in the first direction, the second opening limiting protrusion 346 may contact the other end of the stopper 380. In response to the second opening limiting protrusion 346 contacting the other end of the stopper 380, the rotation opening guide 340 no longer rotates in the first direction due to interference between the stopper 380 and the second opening limiting protrusion 346. In other words, when the opening drive motor 310 operates despite the switching protrusion 371 being pressed, the second opening limiting protrusion 346 contacts the stopper 380, thereby stopping the rotation of the rotation opening guide 340 in the first direction.
[0093] Referring to FIG. 10, the dust container cover 11 may include a cover protrusion 11a and a cover groove 11b. The button 17 may include a button protrusion 17a and a button groove 17b. The dust container cover 11 may be closed by inserting the cover protrusion 11a of the dust container cover 11 into the button groove 17b, and inserting the button protrusion 17a of the button 17 into the cover groove 11b.
[0094] The cover closing device 400 may form a portion of a channel provided within the duct portion 120. More specifically, the rotary lever 440 of the cover closing device 400 may be provided to form a portion of an inner surface of the duct portion 120.
[0095] FIG. 11 shows a state in which the cover opening device shown in FIG. 7 opens the dust container cover. FIG. 12 shows a front view of the cover opening device shown in FIG. 11. FIG. 13 shows a side cross-section of the cover opening device and the cover closing device shown in FIG. 11.
[0096] Referring to FIG. 11, the opening drive motor 310 may open the dust container cover 11 by rotating the opening drive shaft 311 in the second direction opposite to the first direction. According to an embodiment of the present disclosure, the second direction may refer to a counterclockwise direction.
[0097] As the opening drive shaft 311 rotates in the second direction, the first opening link 320 may rotate together with the opening drive shaft 311 in the second direction. The second opening link 330 may move upward as the first opening link 320 rotates in the second direction. The rotation opening guide 340 may rotate in the second direction as the second opening link 330 moves upward. The rotation opening guide 340 may rotate in the same direction as the first opening link 320. In other words, the rotation opening guide 340 may rotate in the second direction in response to the first opening link 320 rotating in the second direction.
[0098] As the rotation opening guide 340 rotates in the second direction, the rotation opening guide 340 may press the push lever 360. The push lever 360 may rotate about a lever rotation shaft 363 by the rotation opening guide 340. As the push lever 360 rotates about the lever rotation shaft 363, a push protrusion 361 of the push lever 360 may press the button 17. The dust container cover 11 may be opened by pressing the button 17. As described above, because the dust container cover 11 is provided with an elastic force in a direction in which the dust container cover 11 is closed, the draw-in force from the intake portion 150 is required to be provided to open the dust container cover 11.
[0099] Referring to FIG. 12, in response to the opening drive shaft 311 rotating in the second direction by the driving force of the opening drive motor 310, the first opening link 320 rotates in the second direction and thus the second opening link 330 may move upward. As the second opening link 330 moves upward, the rotation opening guide 340 may rotate in the second direction.
[0100] According to an embodiment of the present disclosure, the push lever 360 may rotate about the lever rotation shaft 363 by rotating the rotation opening guide 340 in the second direction. This is because, in response to the rotation opening guide 340 rotating in the second direction, the rotation opening guide 340 may press the push lever 360 to allow the push lever 360 to rotate.
[0101] As the rotation opening guide 340 rotates in the second direction, the first opening limiting protrusion 345 of the rotation opening guide 340 may come into contact with one end of the stopper 380. As the first opening limiting protrusion 345 contacts one end of the stopper 380, the rotation of the rotation opening guide 340 in the second direction may be restricted. In other words, the rotation range of the rotation opening guide 340 in the second direction may be restricted due to physical contact between the first opening limiting protrusion 345 and the stopper 380. In contrast, the opening drive motor 310 may rotate the opening drive shaft 311 in the second direction by a predetermined angle. For example, the opening drive motor 310 may be preset to rotate the opening drive shaft 311 by approximately 60° in the second direction. In response to the opening drive shaft 311 rotating by approximately 60° in the second direction, the rotation opening guide 340 may be provided to press the push lever 360.
[0102] According to an embodiment of the present disclosure, when the rotation opening guide 340 rotates in the first direction, the second opening limiting protrusion 346 may press the switching protrusion 371 to reset the reference position of the opening drive shaft 311. Although the opening drive motor 310 is preset to rotate the opening drive shaft 311 in the second direction by the predetermined angle, the reference position may deviate from an initial setting position when the opening drive shaft 311 repeatedly rotates in the first and second directions. Because the reference position may be reset each time the opening drive shaft 311 rotates in the first direction, it is possible to prevent the reference position of the opening drive shaft 311 from deviating from the initial setting position.
[0103] Referring to FIG. 13, in response to the rotation opening guide 340 rotating in the second direction, the second opening pressing portion 342 of the rotation opening guide 340 may press a pressing surface 362 of the push lever 360. The rotation opening guide 340 may include the first opening pressing portion 341 that is relatively thin, and the second opening pressing portion 342 that is relatively thick. The first opening pressing portion 341 and the second opening pressing portion 342 may be connected to each other, and may be provided to allow the thickness to increase from the first opening pressing portion 341 to the second opening pressing portion 342. In response to the rotation opening guide 340 rotating in the second direction, the first opening pressing portion 341 may begin to come into contact with the pressing surface 362, and the second opening pressing portion 342 may press the pressing surface 362. In other words, the first opening pressing portion 341 and the second opening pressing portion 342 may be provided to gradually press the pressing surface 362.
[0104] If the opening drive shaft 311 extends in a third direction, the first opening link 320, the second opening link 330, and the rotation opening guide 340 may each rotate about a rotation axis parallel to the third direction. The push lever 360 may rotate about the lever rotation shaft 363 extending in a fourth direction intersecting the third direction.
[0105] In response to the push protrusion 361 of the push lever 360 pressing the button 17, the button 17 may rotate about the button rotation shaft 17c parallel to the fourth direction. When the button 17 rotates about the button rotation shaft 17c, the cover protrusion 11a of the dust container cover 11 may pulled out of the button groove 17b, and the button protrusion 17a may be pulled out of the cover groove 11b. The cover protrusion 11a may be pulled out of the button groove 17b, and the button protrusion 17a may be pulled out of the cover groove 11b, so that the dust container cover 11 may be opened. The button rotation shaft 17c may be provided parallel to the lever rotation shaft 363. In other words, the button rotation shaft 17c may extend in a direction parallel to the fourth direction.
[0106] FIG. 14 shows a state in which the cover closing device shown in FIG. 7 closes the dust container cover. FIG. 15 is a view showing the inside of the duct portion when the rotary lever is in a second position as shown in FIG. 14.
