[0037] When an element is referred to as being “on another element,” it means that the element is in contact with the other element, or another element is present between the element and the other element.

[0038] A cleaner, for example, a vacuum cleaner, sucks air with foreign matter such as dust by the suction force generated by a suction fan, filters the foreign matter out of the air, and contains the foreign matter in a dust collection container. The cordless cleaner receives power from a battery to perform a cleaning operation. The battery can be disassembled from the cordless cleaner. A controller is provided in the cleaner. Control of the operation of the cleaner, such as power on / off, can be performed by using the controller. As the use condition of the cleaner changes, the shape and function of the controller can also change. The present disclosure provides a cleaner having a structure in which the controller can be disassembled from the cleaner. According to the user's preference, the aesthetic elements of the cleaner can be improved by disassembling the controller from the top of the cleaner and replacing the controller with another controller having a different design. In addition, by installing a controller having a manipulation unit and an indication unit suitable for the use condition of the cleaner on the cleaner, the convenience of use and manipulability of the cleaner can be improved.

[0039] The cleaner includes a filter that eventually filters out fine dust in the air that has traveled through the dust collector. The filter is mounted in a filter housing. In order to replace the filter, the filter housing can be separated from the main body of the cleaner. In the cleaner of the present disclosure, the filter housing is separated from the cleaner in a rearward direction. The cleaner includes a handle to be held by a user. A controller is arranged at the rear of the filter housing to allow a user holding the handle to easily manipulate the controller. A structure in which the controller can be detached from the cleaner enables the use of various controllers and enables the filter housing to be separated from the rear of the cleaner.

[0040] The performance of the cleaner is affected by the resistance of the air flow path (i.e., flow path resistance). For a cordless cleaner using a rechargeable battery, by reducing the flow path resistance, the suction efficiency and battery efficiency can be improved. The cleaner of the present disclosure has a reverse motor structure in which the impeller is located downstream of the suction motor. As the flow resistance to the air sucked in by the suction fan and discharged through the filter is improved, the battery efficiency related to the output can be increased, and as the battery efficiency is improved, the use time of the vacuum cleaner that needs to be charged before use can be increased.

[0041] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. In the drawings, similar reference numerals indicate parts or components that perform substantially the same function.

[0042] Figure 1is a schematic partial cross-sectional perspective view of a cleaning device according to an embodiment of the present disclosure. Figure 1 The exemplary cleaner shown is a pole-type cordless cleaner. Figure 1 , the cleaner may include a main body 100 and a controller 180 for controlling the operation of the cleaner. The main body 100 may include: a suction fan 191 for generating a suction force for sucking air, a dust collector 192 for separating foreign matter from the sucked air, and a filter 197 for filtering foreign matter from the air that has passed through the dust collector 192. The filter 197 is accommodated in a filter housing 198. The controller 180 is located at the rear of the filter housing 198. The controller 180 can be detached from the main body 100.

[0043] The main body 100 may include an extension pipe coupling unit 110 to which an extension pipe (not shown) is coupled. A suction nozzle (not shown) is detachably connected to one end of the extension pipe. The other end of the extension pipe may be detachably coupled to the extension pipe coupling unit 110 of the main body 100. The extension pipe connects the main body 100 to the suction nozzle to form a passage through which air and foreign matter sucked in through the suction nozzle move to the main body 100. A suction fan 191 for generating a suction force required for sucking in air with foreign matter on a surface to be cleaned, a dust collector 192 for separating foreign matter from the sucked air, a dust collection container 193 for accommodating the separated foreign matter therein, and a filter housing 198 for accommodating a filter 197 are provided in the main body 100.

[0044] The suction fan 191 may include a suction motor 191a and an impeller 191b, which is mounted on the rotating shaft of the suction motor 191a. When the suction motor 191a is driven to rotate the impeller 191b, a suction pressure is generated for sucking air and foreign matter on the surface to be cleaned through the air intake path 195. The air is compressed by the impeller 191b in an adiabatic manner, and the temperature is thus increased. In a structure in which the impeller 191b is located upstream of the suction motor 191a, the suction motor 191a is exposed to high-temperature compressed air. The motor coil of the suction motor 191a is cooled by the sucked air, and when the high-temperature compressed air flows around the suction motor 191a, the motor coil may not be effectively cooled. The high-temperature compressed air may instead cause the temperature of the motor coil to rise, and the power and efficiency of the suction motor 191a may deteriorate. The suction fan 191 according to the present embodiment of the present disclosure has a reverse motor structure, in which the impeller 191b is arranged downstream of the suction motor 191a relative to the air flow direction. According to the present embodiment of the present disclosure, in the suction fan 191 with the reverse motor structure, uncompressed low-temperature air travels around the suction motor 191a. The low-temperature air can effectively cool the motor coil. The motor coil can be maintained at a stable operating temperature, and thus the power and efficiency of the suction motor 191a can be improved.

[0045] An air intake path 195 connecting the extension pipe coupling unit 110 to the dust collector 192 is provided in the main body 100. Foreign matter and air sucked through the suction nozzle by means of the suction force generated by the suction fan 191 are moved to the dust collector 192 via the extension pipe, the extension pipe coupling unit 110 and the air intake path 195. The dust collector 192 may have, for example, a cyclone dust collection structure. The dust collector 192 may be located between the dust collection container 193 and the suction fan 191 relative to the flow path of the sucked air. Foreign matter is separated from the sucked air by the dust collector 192 and then contained in the dust collection container 193. The dust collection container 193 can be detached from the main body 100. For example, by pulling the front portion of the dust collection container 193, the dust collection container 193 may be separated from the main body 100. After the dust collection container 193 is separated from the main body 100, the foreign matter collected in the dust collection container 193 may be removed.

[0046] An exhaust path 196 for discharging air from which foreign matter has been removed is provided in the main body 100. The exhaust path 196 is provided downstream of the suction fan 191. The filter 197 may be provided at the inlet of the exhaust path 196, in the exhaust path 196, or at the outlet of the exhaust path 196. In the present embodiment of the present disclosure, the filter 197 is provided at the outlet of the exhaust path 196. There is no particular limitation on the type of the filter 197. The filter 197 may include, for example, a high efficiency particulate air (HEPA) filter. The filter 197 may filter out ultrafine dust and the like that has not been filtered out by the dust collector 192. The filter 197 may be accommodated in a filter housing 198. The air from which foreign matter has been removed may be discharged to the outside after traveling through the exhaust path 196 and the filter 197. An exhaust port 199 may be provided in the filter housing 198, through which the air that has traveled through the exhaust path 196 and the filter 197 is discharged.

[0047] The filter housing 198 can be disassembled from the main body 100 for maintenance of the filter 197, such as cleaning or replacement. The filter housing 198 can have a forward separation structure, in which the filter housing 198 moves forward to separate from the main body 100. The forward separation structure is disadvantageous in terms of user convenience, because the dust collection container 193 needs to be separated from the main body 100 first, so as to separate the filter housing 198 from the main body 100. In addition, since the filter 197 needs to be located relatively far in front of the outlet of the suction fan 191, the curvature of the exhaust path 196 may be very high, resulting in an increase in the resistance of the flow path. This may cause the deterioration of the suction efficiency of the suction fan 191. In the cleaner of the present embodiment of the present disclosure, the filter housing 198 has a backward separation structure, in which the filter housing 198 moves backward to separate from the main body 100. That is, the filter housing 198 can be disassembled from the main body 100 in the backward direction. The backward separation structure is advantageous in terms of user convenience, because the filter housing 198 can be separated from the main body 100 without separating the dust collection container 193 from the main body 100. In addition, since the filter 197 can be located near the outlet of the suction fan 191, the curvature of the exhaust path 196 can be low, and therefore, the resistance of the flow path can be less than the resistance of the flow path of the forward separation structure. Therefore, the suction efficiency of the suction fan 191 can be improved. After the filter housing 198 is separated from the main body 100, the filter 197 accommodated in the filter housing 198 can be replaced with a new filter 197. Alternatively, the filter 197 accommodated in the filter housing 198 can be cleaned.

[0048] The main body 100 includes a frame 101 for supporting or accommodating the above-mentioned components of the cleaner. For example, the frame 101 may include: a support portion 102 extending in the front-to-back direction (X), a battery mounting portion 103 extending in the front-to-back direction (X) in parallel with the support portion 102, and a support portion 104 connecting the support portion 102 to the battery mounting portion 103. The support portion 102 may extend beyond the support portion 104 in the rearward direction (X). The dust collection container 193, the dust collector 192, the suction fan 191, and the filter housing 198 may be arranged in the front-to-back direction (X) and arranged above the support portion 102. The extension pipe coupling unit 110 may be arranged at the front of the support portion 102. The air intake path 195 is arranged inside the support portion 102 and extends from the extension pipe coupling unit 110 to the dust collector 192. The exhaust path 196 may be arranged downstream of the suction fan 191 and above the support portion 102. The battery 900 may be mounted on the battery mounting portion 103 or may be separated from the battery mounting portion 103. The support portion 104 may connect the front end of the battery mounting portion 103 to the support portion 102. For example, the support portion 104 may be inclined forward from the lower end to the upper end.

[0049] The main body 100 may include a handle 105 that can be grasped by a user. The user holding the handle 105 can move and manipulate the cleaner. The handle 105 may be located at the rear of the support 104. For example, the handle 105 may connect the rear end of the battery mounting portion 103 to the rear end of the support 102. Considering the convenience of use, the handle 105 may be tilted forward from the lower end to the upper end. For example, the upper end of the handle 105 may form an obtuse angle with the support 102, and the lower end of the handle 105 may form an acute angle with the battery mounting portion 103. The handle 105 may have a size suitable for the user to comfortably grasp the handle 105.

[0050] The controller 180 is located at the rear of the filter housing 198. The controller 180 may be located near the rear end of the support 102 and above the handle 105. A user holding the handle 105 may use the cleaner. Here, the controller 180 may naturally enter the user's field of vision, and thus improve the convenience of use. In addition, the user may easily manipulate the controller 180 with the thumb of the hand holding the handle 105 or with the other hand.

[0051] The controller 180 may include a control circuit unit and a manipulation unit 181 for performing manipulation input, such as power on / off, adjusting suction intensity, or changing operation mode. The controller 180 may also include an indication unit 182, which is configured to display information about the operating state of the cleaner. The manipulation unit 181 may include a physical button, a resistive or capacitive touch panel, etc. The manipulation unit 181 may have a structure that enables manipulation input by voice recognition and manipulation input by communication with an external control device. The indication unit 182 may indicate the operating state of the cleaner in an auditory manner and in a visual manner. For example, the indication unit 182 may include a buzzer, a display, one or more light-emitting units, etc. When a touch panel display is adopted, the manipulation unit 181 and the indication unit 182 may be integrated into one unit. The control circuit unit may control the cleaner according to the manipulation input performed by the manipulation unit 181, and may control the indication unit 182 to indicate information about the operating state of the cleaner.

[0052] As described above, the controller 180 can be detached from the body 100. For example, the controller 180 can be attached to or detached from the body 100 by sliding in the front-rear direction (X), the lateral direction (Y), or the up-down direction (Z), for example.

[0053] Figure 2 1 is a partially exploded perspective view illustrating a structure in which the controller 180 is attached to or detached from the cleaner in the up-down direction (Z) according to an embodiment of the present disclosure. Figure 2 , a socket 300 may be provided in the body 100, through which the controller 180 is supported in a detachable manner. For example, the socket 300 may be provided in the filter housing 198. For example, the socket 300 may be formed integrally with the filter housing 198, or the socket 300 may be coupled to the filter housing 198. Therefore, the controller 180 is directly coupled to the filter housing 198, or is indirectly coupled to the filter housing 198 via the socket 300. The socket 300 includes a housing portion 310, in which the controller 180 is detachably accommodated. The housing portion 310 may extend in the up-down direction (Z), and may have an open top. For example, the housing portion 310 may be defined by a pair of side walls 311, a lower wall 312, and a front wall 313, the pair of side walls 311 being spaced apart from each other in the lateral direction (Y), the lower wall 312 connecting the lower ends of the pair of side walls 311 to each other, and the front wall 313 connecting the front ends of the pair of side walls 311 to each other.

[0054] The first guide portion 320 is provided to guide the controller 180 to be attached to or detached from the socket 300. The first guide portion 320 extends in the direction of attaching and detaching the controller 180, that is, in the up-down direction (Z). For example, the first guide portion 320 may be provided on each of the pair of side walls 311. The second guide portion 184 to be guided by the first guide portion 320 is provided in the controller 180. The first guide portion 320 and the second guide portion 184 may have complementary shapes for relative movement in the direction of attachment and detachment. For example, the first guide portion 320 may have a groove shape extending in the up-down direction (Z), and the second guide portion 184 may have a shape protruding from both side walls of the controller 180 in the lateral direction (Y) so as to be inserted into the first guide portion 320. Although not shown in the drawings, the first guide portion 320 may have a protruding shape, and the second guide portion 184 may have a groove shape. In addition to the above-described examples, the first guide portion 320 and the second guide portion 184 may also have complementary shapes for relative movement in the directions of attachment and detachment.

[0055] Figure 3 1 is a schematic side view illustrating an electrical connection structure between the main body 100 and the controller 180 according to an embodiment of the present disclosure. Figure 2 and Figure 3 In order to electrically connect the main body 100 to the controller 180, a first connector 183 is provided in the controller 180. The controller 180 may include a printed circuit board 185 having a control circuit unit. One or more printed circuit boards 185 may be provided. The manipulation unit 181 and the indication unit 182 may be electrically connected to the printed circuit board 185 (e.g., a control circuit board) through a connection unit (not shown), such as a wire, a cable, a connector, or a flexible circuit board. The first connector 183 is provided on the printed circuit board 185. For example, the first connector 183 may be provided at the lower end of the printed circuit board 185. The first connector 183 may have various types depending on the shape and connection method of the first connector. For example, the first connector 183 may include, but is not limited to, a detachable connector for repeated attachment and detachment, a board-to-board (B-to-B) connector, and a C-type connector.

[0056] A second connector 410 for engaging the first connector 183 may be provided in the main body 100. The second connector 410 may be formed to be complementary to the first connector 183. A printed circuit board 401 (first printed circuit board) is provided in the main body 100. The printed circuit board 401 is electrically connected to the battery 900 and control elements of the main body 100 including the suction motor 191a and the sensor. For example, the printed circuit board 401 may be housed in the support portion 104. A printed circuit board 402 (second printed circuit board) may be provided in the support portion 102. The printed circuit board 402 may be located near the rear end of the support portion 102. The second connector 410 is provided on the printed circuit board 402. The printed circuit board 401 and the printed circuit board 402 are electrically connected to each other via a wire 403.

[0057] The second connector 410 is exposed to the interior of the receiving portion 310 through an opening 314 provided in a lower wall 312 forming the receiving portion 310. The controller 180 is inserted into the receiving portion 310 by aligning the second guide portion 184 with the first guide portion 320 and moving the controller 180 downward. When the controller 180 is fully inserted into the receiving portion 310, the first connector 183 is engaged with the second connector 410. Therefore, the controller 180 can communicate with the battery 900 and the control elements of the main body 100.

[0058] The controller 180 may be fixed to the main body 100 through various fixing structures. For example, the controller 180 may be fixed to the main body 100 through a snap-fit ​​fixing structure, a magnetic fixing structure, a screw fastening structure, and the like.

[0059] Figure 4 The figure illustrates a snap-fit ​​fixing structure according to an embodiment of the present disclosure. Figure 4 According to an embodiment of the present disclosure, the snap-fit ​​fixing structure may include a capture portion 514 and an elastic locking portion 513, the capture portion 514 being provided in any one of the controller 180 and the socket 300, and the elastic locking portion 513 being provided in the other of the controller 180 and the socket 300 so as to be elastically captured or locked by the capture portion 514. In the present embodiment of the present disclosure, the capture portion 514 is provided in the controller 180, and the elastic locking portion 513 is provided in the socket 300. For example, the elastic locking portion 513 may include an elastic arm 511, the elastic arm 511 being provided on the front wall 313 of the socket 300 to be elastically bent in the front-rear direction (X), and an engaging protrusion 512 being provided at one end of the elastic arm 511. The capture portion 514 has a shape that can capture or lock the engaging protrusion 512. For example, the capture portion 514 may be concavely formed on the front wall 186 of the controller 180.

[0060] When the controller 180 is inserted into the receiving portion 310 of the socket 300 and then slides downward, the front wall 186 of the controller 180 pushes the engaging protrusion 512 forward, so that the elastic arm 511 bends forward. When the installation of the controller 180 is completed, the elastic arm 511 elastically returns to its original position, and the engaging protrusion 512 is thereby captured or locked by the catch portion 514, so that the controller 180 can be fixed to the socket 300. Unless a force greater than or equal to the elastic force of the elastic arm 511 is applied, the controller 180 can remain fixed to the socket 300. By sliding the controller 180 upward with a force greater than the elastic force of the elastic arm 511 to separate the controller 180 from the socket 300, the engaging protrusion 512 is pushed forward by the catch portion 514, and the elastic arm 511 bends forward, so that the engaging protrusion 512 is separated from the catch portion 514. By continuously sliding the controller 180 upward, the controller 180 can be separated from the receiving portion 310 of the socket 300. When the controller 180 is detached from the socket 300 , the elastic arm 511 elastically returns to its original position.

[0061] Figure 5 FIG. 1 illustrates a magnetic fixing structure according to an embodiment of the present disclosure. Figure 5 According to an embodiment of the present disclosure, the magnetic fixing structure may include a magnet 521 and a magnetic member 522, the magnet 521 being provided in any one of the controller 180 and the socket 300, and the magnetic member 522 being provided in the other of the controller 180 and the socket 300. The magnetic member 522 is a member capable of being adsorbed to the magnet 521, such as iron. In the present embodiment of the present disclosure, the magnetic member 522 is provided in the controller 180, and the magnet 521 is provided in the socket 300. For example, the magnet 521 may be provided on the front wall 313 of the socket 300, and the magnetic member 522 may be provided on the front wall 186 of the controller 180 facing the front wall 313. When the controller 180 is inserted into the receiving portion 310 of the socket 300, the magnetic member 522 may be attached to the magnet 521 by the magnetic force of the magnet 521, and the controller 180 may be fixed to the socket 300. By sliding the controller 180 upward with a force greater than the magnetic force of the magnet 521 to separate the controller 180 from the socket 300 , the magnetic member 522 may be separated from the magnet 521 , and the controller 180 may be separated from the receiving portion 310 of the socket 300 .

[0062] Figure 6 The figure shows a screw fastening structure according to an embodiment of the present disclosure. Figure 6, a locking portion 187 inserted into the handle 105 is provided in the controller 180. For example, the locking portion 187 extends downward from the lower end of the controller 180. The locking portion 187 may be located behind the first connector 183. A locking hole 188 is provided in the locking portion 187. An opening 314 is provided in the lower portion of the socket 300, for example, in the lower wall 312. The above-mentioned second connector 410 is exposed upward through the opening 314. The opening 314 provides a passage through which the locking portion 187 is inserted into the handle 105.

[0063] When the controller 180 is mounted on the socket 300, the locking portion 187 is inserted into the handle 105 through the opening 314. A screw fastening hole 531 aligned with the locking hole 188 is provided in the handle 105. The controller 180 can be fixed to the main body 100 by screwing the screw 532 through the locking hole 188 into the screw fastening hole 531. The cover 533 can cover the screw fastening hole 531. The cover 533 can be coupled to the handle 105 in a detachable manner. In order to maintain the appearance quality of the cleaner, the cover 533 can have a shape that matches the appearance of the handle 105. The cover 533 can be formed by, for example, rubber, etc. The controller 180 can be separated from the main body 100 by separating the cover 533 from the handle 105, loosening the screw 532, and then sliding the controller 180 upward to separate the controller 180 from the socket 300.

[0064] As the use condition of the cleaner changes, the shape and function of the controller 180 may also change. According to the present disclosure, the controller 180 can be detached from the main body 100. According to the user's preference, by detaching the controller 180 from the main body 100 and replacing the controller 180 with another controller 180 having a different design, the aesthetic element of the cleaner can be improved. In addition, by installing a controller 180 having a manipulation unit 181 and an indication unit 182 suitable for the use condition of the cleaner on the cleaner, the convenience of use and manipulability of the cleaner can be improved.

[0065] Figures 7a to 7e Various examples of the controller 180 are shown. Figure 7a , the controller 180a according to an embodiment of the present disclosure is a conventional or standard controller with an indication unit 182a having a quadrilateral shape and a standard size. The controller 180a may have a form factor that is smaller than the form factor of the filter housing 198, for example, including a length in the lateral direction (horizontal direction) (Y) and a length in the up-down direction (vertical direction) (Z). In other words, the projection area of ​​the controller 180a along the front-to-back direction (X) on the YZ plane is within the projection area of ​​the filter housing 198 along the front-to-back direction (X) on the YZ plane. Reference Figure 7bAccording to an embodiment of the present disclosure, the controller 180b and Figure 7a The illustrated controller 180a differs in that the indication unit 182b has a circular shape.

[0066] At least one of the shape factors of the controller 180 may be greater than the shape factor of the filter housing 198. The shape factor of the filter housing 198 refers to a parameter that determines the shape and size of a projection area of ​​the filter housing 198 along the attachment or removal direction of the filter housing. Similarly, the shape factor of the controller 180 refers to a parameter that determines the shape and size of a projection area of ​​the controller 180 along the attachment or removal direction of the filter housing 198. For example, in the case where the appearance of the filter housing 198 has a cylindrical shape, the diameter of the maximum cross-section of the filter housing 198 on the YZ plane is the shape factor of the filter housing 198. The controller 180 may include the longest length of the controller 180 in the lateral direction (Y) and the longest length in the up-down direction (Z).

[0067] refer to Figure 7c According to an embodiment of the present disclosure, the controller 180c includes an indication unit 182c, which is larger than the upper and lower directions (Z). Figure 7a The indicating unit 182a of the controller 180a shown in FIG is longer. The length of the controller 180c in the up-down direction (Z) is greater than the diameter of the filter housing 198. The controller 180c extends upward beyond the periphery of the filter housing 198. That is, the projection area of ​​the controller 180c on the YZ plane exceeds the projection area of ​​the filter housing 198 on the YZ plane in the up-down direction (Z).

[0068] refer to Figure 7d According to an embodiment of the present disclosure, the controller 180d includes an indication unit 182d, which is larger than the horizontal direction (Y). Figure 7a The indicating unit 182a of the controller 180a shown is longer. The length of the controller 180d in the transverse direction (Y) is greater than the diameter of the filter housing 198. The controller 180d extends beyond the periphery of the filter housing 198 in the transverse direction (Y). That is, the projection area of ​​the controller 180d on the YZ plane exceeds the projection area of ​​the filter housing 198 on the YZ plane in the transverse direction (Y).

[0069] refer to Figure 7e According to an embodiment of the present disclosure, the controller 180e includes an indication unit 182e which is larger than the vertical direction (Z) and the horizontal direction (Y). Figure 7aThe indicating unit 182a of the controller 180a shown is longer. The controller 180e extends beyond the periphery of the filter housing 198 in the up-down direction (Z). The length of the controller 180e in the up-down direction (Z) and the length in the lateral direction (Y) are both greater than the diameter of the filter housing 198. That is, the projection area of ​​the controller 180e on the YZ plane exceeds the projection area of ​​the filter housing 198 on the YZ plane in the up-down direction (Z) and the lateral direction (Y).

[0070] Therefore, the controller 180 including the indication unit 182 having various sizes and shapes may be installed on the main body 100 to reflect the needs of the user. Figures 7a to 7e Although not shown in the figure, various controllers 180 having various exterior colors and including the manipulation unit 181 having different colors and shapes may be provided, and an appropriate controller 180 may be mounted on the body 100 according to the user's preference.

[0071] Another controller 180 having multiple functions reflecting the user's usage mode may be installed on the main body 100 to replace the existing controller 180. For example, a standard controller capable of selecting a normal mode, a strong suction mode, and an extra-strong suction mode; a professional controller capable of selecting a normal mode, an energy-saving mode, a strong suction mode, an extra-strong suction mode, and a spray mode; or an advanced controller capable of selecting a normal mode and an extra-strong suction mode and displaying information in a large size. For example, the standard controller and the professional controller may have Figures 7a to 7e For example, a high-end controller may have a shape for displaying large letters, such as Figure 7d and Figure 7e shown.

[0072] As described above, the cleaning machine of the present disclosure includes the filter housing 198, which can be separated from the cleaning machine in the rearward direction. The detachable controller 180 enables the filter housing 198 to be separated from the cleaning machine in the rearward direction. Figure 8 1 is a schematic side view illustrating a state in which the filter case 198 is separated from the main body 100. Figure 8, since the controller 180 is arranged at the rear of the filter housing 198, before separating the filter housing 198 from the main body 100, the controller 180 is first separated from the main body 100. For example, the cover 533 is removed from the handle 105 to expose the screw fastening hole 531. The fixing of the controller 180 is released by loosening the screw 532. Then, by sliding the controller 180 upward, the controller 180 is separated from the socket 300. Then, by sliding the filter housing 198 backward, the filter housing 198 can be separated from the main body 100. The socket 300 is separated from the main body 100 in a manner integrated with the filter housing 198.

[0073] After replacing or cleaning the filter 197, the filter housing 198 may be mounted on the main body 100. The filter housing 198 may be fixed to the main body 100, for example, by hooking on a hook 106 provided on the main body 100. Then, the controller 180 is inserted into the socket 300 by aligning the controller 180 with the receiving portion 310 of the socket 300 and then sliding the controller 180 downward. When the controller 180 is fully inserted into the socket 300, the first connector 183 is coupled to the second connector 410 of the main body 100. The locking portion 187 is inserted into the handle 105, and the locking hole 188 is aligned with the screw fastening hole 531. The controller 180 may be fixed to the main body 100 by fastening the screw 532 through the locking hole 188 into the screw fastening hole 531. The screw fastening hole 531 may be covered by coupling the cover 533 to the handle 105.

[0074] According to the conventional cleaner, a filter housing having a hollow cylindrical shape is adopted. In order to allow the filter housing to be separated from the main body when sliding backward, the size of the controller needs to be smaller than the inner diameter of the hollow portion of the filter housing. Therefore, the size of the indicating unit is limited, and it is difficult to adopt a controller having various sizes and shapes.

[0075] According to the cleaner of the present disclosure, the controller 180 can be separated from the main body 100. By first separating the controller 180 from the main body 100, and then sliding the filter housing 198 backward, the filter housing 198 can be separated from the main body 100. Therefore, the backward separation of the filter housing 198 is not limited by the size or shape of the controller 180. According to an embodiment of the present disclosure, according to a cleaner including a filter housing 198 that can be separated from the cleaner in the backward direction, the filter 197 can be easily replaced, so that the cleaner can be easily kept clean and can perform a high-performance cleaning operation. In addition, since the filter 197 can be positioned relatively close to the outlet of the suction fan 191, the curvature of the exhaust path 196 is relatively small, whereby the resistance of the flow path is relatively low, and the suction efficiency of the suction fan 191 can be improved. In addition, compared with the power of the suction fan 191, the efficiency of the battery 900 is improved, and therefore, the use time of the cordless cleaner that needs to be charged before use can be increased. Furthermore, since the controller 180 having various sizes, shapes, and functions may be used, user convenience may be improved.

[0076] In the above-described embodiment of the present disclosure, the controller 180 slides in the up-down direction (Z) to be attached to or detached from the body 100 (eg, the socket 300 ), but the sliding direction of the controller 180 may be changed. Fig. 9 A structure in which the controller 180 is attached to or detached from the main body 100 by sliding in the front-rear direction (X) according to an embodiment of the present disclosure is illustrated. Fig. 9 , the socket 300 is provided on the rear surface of the filter housing 198. A first guide portion 320 having a groove shape extending in the front-rear direction (X) is provided inside the socket 300. A second guide portion 184 having a protrusion shape extending in the front-rear direction (X) is provided on the side wall of the controller 180. In order to electrically connect the main body 100 to the controller 180, a first connector 183 is provided in the controller 180. The first connector 183 is provided on a printed circuit board 185 (see Figure 3 ). A second connector 410 for engaging the first connector 183 is provided in the main body 100. The second connector 410 is provided on a printed circuit board 402, which is connected to the printed circuit board 402 by a wire 403 (see Figure 3 ) connected to the printed circuit board 401 (see Figure 3 ). The first connector 183 and the second connector 410 may be coupled to each other in the front-rear direction (X).

[0077] The controller 180 is inserted into the receiving portion 310 of the socket 300 by aligning the second guide portion 184 with the first guide portion 320 and moving the controller 180 forward. When the controller 180 is fully inserted into the receiving portion 310, the first connector 183 engages the second connector 410. Therefore, the controller 180 can communicate with the battery 900 and the control elements of the main body 100. The controller 180 can be fixed to the main body 100 by various fixing structures. For example, the controller 180 can be fixed to the main body 100 by the snap-fit ​​fixing structure or the magnetic fixing structure described above. Although not shown in the drawings, in the snap-fit ​​fixing structure, the elastic locking portion 513 (see Figure 4 ) may be provided on the side wall 311 forming the receiving portion 310, and the capturing portion 514 (see Figure 4 ) may be disposed on a side wall of the controller 180 opposite to the side wall 311. Although not shown in the drawings, the magnetic fixing structure may be provided with Figure 5 Although not shown in the drawings, the controller 180 may be fixed to the body 100 by a screw fastening structure or the like.

[0078] Fig.10 is a rear view illustrating a structure in which the controller 180 is attached to or detached from the main body 100 by sliding in the lateral direction (Y) according to an embodiment of the present disclosure. Fig.10 , the socket 300 is disposed on the rear surface of the filter housing 198. The socket 300 includes a housing portion 310 that is open in the lateral direction (Y). For example, the housing portion 310 may be defined by a pair of walls 316, a side wall 311, and a front wall 313, the pair of walls 316 being arranged in the up-down direction (Z), the side wall 311 connecting one ends of the pair of walls 316 in the lateral direction (Y) to each other. A first guide portion 320 having a groove shape extending in the lateral direction (Y) may be disposed inside the pair of walls 316. A second guide portion 184 having a protrusion shape may be disposed on the upper and lower walls of the controller 180. In order to electrically connect the main body 100 to the controller 180, a first connector 183 is disposed in the controller 180. The first connector 183 is disposed on a printed circuit board 185 (see Figure 3 ). A second connector 410 for engaging the first connector 183 is provided in the main body 100. The second connector 410 is provided on a printed circuit board 402, which is connected to the printed circuit board 402 by a wire 403 (see Figure 3 ) connected to the printed circuit board 401 (see Figure 3 ). The first connector 183 and the second connector 410 may be coupled to each other in the transverse direction (Y).

[0079] The controller 180 is inserted into the receiving portion 310 of the socket 300 by aligning the second guide portion 184 with the first guide portion 320 and moving the controller 180 in the lateral direction (Y). When the controller 180 is fully inserted into the receiving portion 310, the first connector 183 engages the second connector 410. Therefore, the controller 180 can communicate with the battery 900 and the control elements of the main body 100. The controller 180 can be fixed to the main body 100 by various fixing structures. For example, the controller 180 can be fixed to the main body 100 by the snap-fit ​​fixing structure or the magnetic fixing structure described above. In the snap-fit ​​fixing structure, the elastic locking portion 513 can be provided on the front wall 313 forming the receiving portion 310, and the capture portion 514 (see Figure 4 ) may be disposed on the front wall 186 of the controller 180 opposite to the front wall 313 (see Figure 4 Although not shown in the drawings, the magnetic fixing structure may be Figure 5 Although not shown in the drawings, the controller 180 may be fixed to the body 100 by a screw fastening structure or the like.

[0080] Fig.10 The structure according to an embodiment of the present disclosure is illustrated, in which the controller 180 is attached to and detached from the main body 100 by sliding in the left direction (-Y) and the right direction (+Y), respectively, but the present disclosure is not limited thereto. For example, the cleaner may be designed as a structure in which the controller 180 is attached to and detached from the main body 100 by sliding in the right direction (+Y) and the left direction (-Y), a structure in which the controller 180 is attached to and detached from the main body 100 by sliding in the downward direction (-Z) and the upward direction (+Z), respectively, or a structure in which the controller 180 is attached to and detached from the main body 100 by sliding in the upward direction (+Z) and the downward direction (-Z), respectively.

[0081] The controller 180 may be coupled to the filter housing 198 , and thus the controller 180 may be attached to or detached from the main body 100 in a manner of being integrated with the filter housing 198 . Fig.11 is a schematic side view of a cleaning device according to an embodiment of the present disclosure. Fig.11, the socket 300 is disposed on the rear surface of the filter housing 198, and the controller 180 is supported by the socket 300. A printed circuit board 402 including a second connector 410 is located in the main body 100, for example, behind the support portion 102. The filter housing 198 and the controller 180 integrally form a controller assembly 180X1. The controller assembly 180X1 can be attached to or detached from the main body 100 by sliding in the front-rear direction (X). The controller 180 can be fixedly supported by the socket 300, and as described above, the controller 180 can be attached to and detached from the socket 300.

[0082] When the controller assembly 180X1 is slid forward, the first connector 183 and the second connector 410 are coupled to each other, and the front end of the filter housing 198 is captured or locked on the hook 106 provided in the main body 100. Therefore, the controller assembly 180X1 can be fixed to the main body 100. The controller assembly 180X1 can be fixed to the main body 100 by a fixing unit not shown in the drawings. When the controller assembly 180X1 is slid backward, the front end of the filter housing 198 is separated from the hook 106, and the first connector 183 is separated from the second connector 410. Therefore, the controller assembly 180X1 can be separated from the main body 100. In this state, maintenance of the filter 197, such as replacement or cleaning, can be performed. In the case where the controller 180 can be detached from the socket 300, another controller 180 can be installed on the socket 300 to replace the existing controller 180. In the case where the controller 180 is fixedly supported by the socket 300 , another controller assembly 180X1 employing another controller 180 may be mounted on the main body 100 to replace the existing controller assembly 180X1 .

[0083] The controller 180 may be coupled to the handle 105 , and thus the controller 180 may be attached to and detached from the main body 100 in a manner of being integrated with the handle 105 . Fig.12 is a schematic side view of a cleaning device according to an embodiment of the present disclosure. Fig.12 , the controller 180 is supported by the upper end of the handle 105. Although not shown in the drawings, the socket 300 may be provided at the upper end of the handle 105, and the controller 180 may be supported by the socket 300 in a manner that can be detached. The second connector 410 is provided in the body 100, for example, at the rear of the support portion 102. Although not shown in the drawings, the second connector 410 is provided on the printed circuit board 402 (see Figure 3 The handle 105 and the controller 180 integrally form a controller assembly 180X2. The controller assembly 180X2 may be attached to or detached from the body 100 by sliding in the front-rear direction (X).

[0084] When the controller assembly 180X2 is slid forward, the first connector 183 and the second connector 410 are coupled to each other, and the handle 105 is supported by the main body 100. For example, the upper end and the lower end of the handle 105 are supported by the support portion 102 and the battery mounting portion 103, respectively. The controller assembly 180X2 can be fastened to the support portion 102 and / or the battery mounting portion 103 by screws (not shown) or the like. Therefore, the controller assembly 180X2 can be fixed to the main body 100.

[0085] By loosening the screw (not shown) and sliding the controller assembly 180X2 backward, the upper and lower ends of the handle 105 can be separated from the support portion 102 and the battery mounting portion 103, respectively, and the first connector 183 can be separated from the second connector 410. Therefore, the controller assembly 180X2 can be separated from the main body 100. In the case where the controller 180 can be detached from the socket 300, another controller 180 can be installed on the socket 300 to replace the existing controller 180. In the case where the controller 180 is fixedly supported by the socket 300, another controller assembly 180X2 using another controller 180 can be installed on the main body 100 to replace the existing controller assembly 180X2. When the filter 197 needs maintenance (e.g., replacement or cleaning), after the controller assembly 180X2 is separated from the main body 100, the filter housing 198 can be separated from the main body 100.

[0086] The controller 180 may be attached to or detached from the main body 100 in a manner of being integrated with the filter housing 198 and the handle 105 . Fig.13 is a schematic side view of a cleaning device according to an embodiment of the present disclosure. Fig.13 , the filter housing 198 and the controller 180 are supported by the upper end of the handle 105. The controller 180 is located at the rear of the filter housing 198. Although not shown in the drawings, the socket 300 may be provided at the upper end of the handle 105, that is, at the rear of the filter housing 198, and the controller 180 may be supported by the socket 300 in a manner that can be detached. The second connector 410 is provided in the body 100, for example, at the rear of the support portion 102. Although not shown in the drawings, the second connector 410 is located on the printed circuit board 402 (see Figure 3 The handle 105, the filter housing 198 and the controller 180 integrally form a controller assembly 180X3. The controller assembly 180X3 can be attached to or detached from the main body 100 by sliding in the front-rear direction (X).

[0087] When the controller assembly 180X3 is slid forward, the first connector 183 and the second connector 410 are connected to each other, and the upper and lower ends of the handle 105 are supported by the support portion 102 and the battery mounting portion 103, respectively. The front end of the filter housing 198 can be hooked on the hook 106 (see Figure 8 ). The controller assembly 180X3 may be fastened to the support portion 102 or the battery mounting portion 103 by screws (not shown) or the like. Thus, the controller assembly 180X3 may be fixed to the main body 100.

[0088] By loosening the screw (not shown) and sliding the controller assembly 180X3 backward, the hook 106 (see Figure 8 ) releases the front end of the filter housing 198, and the upper and lower ends of the handle 105 are separated from the support portion 102 and the battery mounting portion 103, respectively. The first connector 183 is separated from the second connector 410. Therefore, the controller assembly 180X3 can be separated from the main body 100. In the case where the controller 180 can be removed from the socket 300, another controller 180 can be installed on the socket 300 to replace the existing controller 180. In the case where the controller 180 is fixedly supported by the socket 300, another controller assembly 180X3 using another controller 180 can be installed on the main body 100 to replace the existing controller assembly 180X3. When necessary, maintenance of the filter 197, such as replacement or cleaning, can be performed.

[0089] In order to enable the filter housing 198 to be separated backward, when the filter housing 198 is removed from the cleaner in the backward direction, the controller 180 can be switched to the retreat position so as not to interfere with the filter housing 198. In other words, the controller 180 can switch between the use position located at the rear of the filter housing 198 and the above-mentioned retreat position.

[0090] Fig.14 is a schematic side view of a cleaning device according to an embodiment of the present disclosure. Fig.14, the controller 180 can be rotated to a retreat position 180Y2 and a use position 180Y1 at the rear of the filter housing 198, in which the controller 180 does not interfere with the removal of the filter housing 198 from the cleaner in the rearward direction. The main body 100 may include an upper support 107. The upper support 107 may be located above the filter housing 198 and may extend rearward while surrounding the periphery of the dust collector 192. The upper support 107 may extend from the bearing 102. The upper support 107 may partially surround the filter housing 198. The upper support 107 may completely surround the filter housing 198. In this case, the rear end of the upper support 107 may be open. The controller 180 is supported by a hinge 108 located at the rear end of the upper support 107 in a rotatable manner. The hinge 108 includes an axis along the transverse direction (Y). The printed circuit board 185 of the controller 180 can be electrically connected to the printed circuit board 401 (see Figure 3 ). Although not shown in the drawings, the cleaner may have a fixing structure for fixing the controller 180 to the use position 180Y1. The fixing structure may include, for example, a snap-fit ​​fixing structure, a magnetic fixing structure, a screw fastening structure, etc.

[0091] When the cleaner is in use, the controller 180 is located as shown in FIG. Fig.14 180Y1. In the use position 180Y1, the controller 180 is located at the rear of the filter housing 198 and above the handle 105. Before separating the filter housing 198 from the main body 100, the controller 180 is rotated upward about the hinge 108 so as to be located at the retreat position 180Y2. In the retreat position 180Y2, the controller 180 does not interfere with the filter housing 198 sliding backward from the main body 100. When the controller 180 is located at the retreat position 180Y2, the filter housing 198 can be separated from the main body 100.

[0092] Fig.15 is a schematic perspective view of a cleaner according to an embodiment of the present disclosure. Fig.14 The difference of the cleaner of the embodiment of the present disclosure shown is that the upper support portion 107a completely surrounds the filter housing 198.
