Further, like reference numerals throughout the specification indicate like components.

FIG. 1 illustrates an example of a cleaning appliance 100. The cleaning appliance 100 may include a housing 1 formed in a form of a cylinder with a hollow defined therein, an intake port 11 formed on the housing 1 and an exhaust 15 defined in the housing 1, a fan 5 disposed inside the housing 1 to flow air from the intake port 11 to the exhaust 15, a separator 4 for guiding the air flowed into the intake port 11 to the fan 5 and separating foreign matters from the air using a centrifugal force, and a display 3 for displaying information associated with the cleaning appliance.

A handle 6 is disposed on the housing 1. The handle 6 may be positioned at a point that is symmetrical with (180 degrees apart from) a point where the intake port 11 is located in a space provided by a circumferential face of the housing 1.

As shown in FIG. 2, a housing wall 19 for dividing an internal space of the housing into a lower space (a first space, S1) and an upper space (a second space, S2) of the housing is disposed inside the housing 1. Further, the housing wall 19 includes a wall through-hole S3 for communicating the first space S1 and the second space S2 with each other defined therein.

The intake port 11 is disposed on the circumferential face of the housing 1 to flow outside air into the first space S1. The intake port 11 may include an intake hole 113 defined to penetrate the circumferential face of the housing 1, and an intake pipe 111 extending from the intake hole 113 in a direction to be farther away from a center of the housing 1 (a direction farther away from the handle, a Y-axis direction). Although not shown in the drawings, the cleaning appliance of the present disclosure may further include an extended pipe detachably disposed on the intake pipe 111, and a nozzle disposed at a free end of the extended pipe to flow the foreign matters to the extended pipe.

As shown in FIG. 1, a housing outlet 17 for discharging the foreign matters stored in the housing 1 to the outside is further defined in a bottom face (one face of the housing opposite to the face in which the exhaust is defined) of the housing 1. The housing outlet 17 is opened and closed by a lower cover 18. The lower cover 18 may be pivotably fixed to the housing 1.

The exhaust 15 may include a housing through-hole 151 defined to penetrate a top face of the housing 1 to communicate an interior of the second space S2 with the outside of the housing 1, a housing cover 152 for closing the housing through-hole, a cover through-hole 155 defined to penetrate the housing cover 152, and the exhaust hole 153 penetrating the housing cover 152 to discharge the air in the second space S2 therethrough.

The housing cover 152 may be formed in any shape as long as the housing through-hole 151 is able to be closed. The drawing shows an example of a disk-shaped housing cover for closing the cylindrical housing.

As shown in FIG. 3, the cover through-hole 155 may be defined at a center of the housing cover 152 (a center of the top face of the housing), and the exhaust hole 153 may be defined as a plurality of holes surrounding the cover through-hole 155. Unlike the drawing, the cover through-hole 155 may be defined in a space defined between the center of the housing cover 152 and an edge of the housing cover 152 in a ring or an arc shape.

A first filter 7 for filtering the air flowing from the fan 5 to the exhaust hole 153 may be disposed in the second space S2. The first filter 7 may include a first filter frame 73 detachably fixed to the second space S2, and a first filter body 71 positioned below the housing cover 152 by being supported by the first filter frame.

The first filter body 71 and the first filter frame 73 may be formed in a ring shape. That is, a filter body through-hole 711 in communication with the cover through-hole 155 may be defined at a center of the first filter body 71, and a body first through-hole 731 in communication with the filter body through-hole 711 may be disposed at a center of the first filter frame 73. In addition, a body second through-hole 733 for supplying the air in the second space S2 to the first filter body 71 may be defined in the first filter frame 73. The body second through-hole 733 may include a plurality of through-holes arranged to form a ring to surround the body first through-hole 731.

Therefore, the air inside the second chamber S2 may be discharged to the outside of the housing 1 through the body second through-hole 733 and the exhaust hole 153. In this process, the air may be filtered by the first filter body 71.

As shown in FIG. 2, a mounting portion 2 may be disposed inside the wall through-hole S3. The mounting portion 2 is for providing a mounting space 211 in which a second filter 8 is mounted. The mounting portion 2 may be disposed as a mounting body 21 detachably fixed to the housing wall 19 and positioned inside the wall through-hole S3. The mounting body 21 may be disposed in a cylindrical or faceted cylindrical shape having a hollow defined therein.

As shown in FIG. 4, a mounting body through-hole 213 for communicating the mounting space 211 and the second space S2 with each other may be defined in a top face of the mounting body 21, and a plurality of communicating holes 25 for communicating the mounting space 211 with the first space S1 may be defined in a bottom face 23 of the mounting body 21.

The mounting body 21 may be detachably coupled to the housing wall 19 through a body fastening portion 27. As shown in FIG. 2, the body fastening portion 27 may include a protrusion 271 disposed on an outer circumferential face of the mounting body 21, and a protrusion fastening groove 237 defined in the housing wall 19 to provide a space in which the protrusion 271 is accommodated. The protrusion fastening groove 237 may be defined as a groove in which a face of the housing wall defining the wall through-hole S3 is concavely curved.

The separator 4 is fixed to the mounting body 21. As shown in FIG. 5, when the user opens the housing outlet 17 with the lower cover 18 and pulls the separator 4 to the housing outlet 17, the mounting body 21 and the second filter 8 may be drawn out of the housing 1 together with the separator 4. When the mounting body 21 and the second filter 8 are withdrawn from the housing 1, the user may detach the second filter 8 from the mounting body 21. Therefore, the cleaning appliance having the above-described structure has an effect of facilitating separation and cleaning of the second filter 8.

As shown in FIG. 2, the fan 5 is disposed in the second space S2 to flow the air in the first space S1 to the exhaust hole 153 through the communicating hole 25. Further, the separator 4 is a flow path formed in the first space S1 to guide the air flowed into the intake port 11 to the communicating hole 25. The foreign matters such as dust and the like contained in the air are separated from the air by a centrifugal force while flowing to the fan 5 along the flow path provided by the separator 4, and a specific structure of the separator 4 is as follows.

The separator 4 includes a chamber forming portion 41 for dividing the first space S1 into a first separated chamber 41a and a second separated chamber 41b, and a cyclone forming portion 42 for supplying the air in the second separated chamber 41b to the fan 5. The cyclone forming portion 42 is for providing the centrifugal force to the foreign matters contained in the air by rotating the air flowing to the fan 5.

The chamber forming portion 41 is formed in a hollow cylindrical shape. One end of the chamber forming portion 41 may be fixed to the bottom face 23 of the mounting body, and the other end of the chamber forming portion 41 may include a separated chamber body 411 in contact with the lower cover 18, and a separated chamber wall 417 for separating the second separated chamber 41b formed in the separated chamber body into a separated space 418 and a storage space 419.

The separated chamber body 411 includes a plurality of through-holes 413 communicating the first separated chamber 41a and the separated space 418 with each other. Therefore, the air flowed into the first separated chamber 41a through the intake port 11 may be supplied to the separated space 418 through the through-hole 413.

An outlet 415 is defined in a bottom face of the separated chamber body 411 in contact with the lower cover 18. Accordingly, the foreign matters stored in the storage space 419 may be discharged to the outside of the housing 1 through the outlet 415 when the lower cover 18 opens the housing outlet 17.

As shown in FIG. 4, each cyclone forming portion 42 may have one end fixed to the bottom face 23 of the mounting body, and the other end including a flow path body 421 penetrating through the separated chamber wall 417 and in communication with the storage space 419, each discharge pipe 424 having one end connected to the mounting space 211 and the other end located inside the flow path body 421, each inlet 423 defined to penetrate a circumferential face of the flow path body 421, and each air flow forming portion 425 forming a spiral flow path between an outer circumferential face of the discharge pipe 424 and an inner circumferential face of the flow path body. Each discharge pipe 424 may be disposed as a pipe fixed to each communicating hole 25. Each flow path body 421 may be disposed as a pipe fixed to the bottom face 23 of the mounting body to surround each communicating hole.

In one example, each foreign matter outlet 422 is defined at a free end of each flow path body 421 (a bottom face of the flow path body) positioned in the storage space 419. Thus, each flow path body 421 is in communication with the storage space 419 through each foreign matter outlet 422. Each flow path body 421 may be disposed to decrease in diameter toward the free end thereof. This is to strongly maintain a strength of the air flow formed therein. Each inlet 423 is located at a point higher than each air flow forming portion 425. Therefore, when the fan 5 is operated, the air flowing into the flow path body 421 through the inlet 423 flows to the discharge pipe 424 via the air flow forming portion 425. In this process, the air will flow while rotating inside the flow path body 421 (cyclone flow).

When the cyclone flow occurs in the flow path body 421, the foreign matters contained in the air will flow to an edge of the flow path (the circumferential face of the flow path body) by the centrifugal force, and then be discharged to the storage space 419 by gravity.

As shown in FIG. 2, the fan 5 is disposed in the second space S2 of the housing to flow the air flowed into the communicating hole 25 to the exhaust hole 153. The fan 5 may include a casing 51 disposed in the wall through-hole S3, an impeller 57 rotatably disposed inside the casing, and a motor 54 fixed to the casing to rotate the impeller 57. The casing 51 may be disposed in a hollow cylinder shape. Further, a casing intake hole 511 and a casing exhaust hole 513 are defined in the casing 51. The casing intake hole 511 may be defined to guide the air flowed through the communicating hole 25 of the mounting portion into the casing 51, and the casing exhaust hole 513 may be defined to discharge the air in the casing 51 to the second space S2.

When the mounting body 21 is disposed in the wall through-hole S3, the casing 51 may be fixed to the second space S2 (the mounting body, the wall, or the interior of the second space) such that the casing intake hole 511 is defined inside the mounting space 211. The motor 54 may be fixed to a support 515 fixed inside the casing 51. In this case, the casing exhaust hole 513 may be defined as a support through-hole passing through the support 515.

The impeller 57 is disposed to be positioned between the casing intake hole 511 and the casing exhaust hole 513, and a rotation shaft 541 of the motor penetrates the support 515 and is connected to the impeller 57.

The motor 54 may be disposed to receive power through a power source disposed in the room, or may be disposed to receive the power through a battery 65 detachable from the housing 1. When the handle 6 is disposed to include a handle body 61 protruding in a direction farther away from the intake port on a rear face (a face opposite to the face on which the intake port is positioned) of the housing 1, the handle body 61 may include a battery housing 63 in which the battery 65 is detachably accommodated.

In one example, the second filter 8 is disposed in the mounting body 21 for filtration of foreign matters not removed by the separator 4. As shown in FIG. 6, the second filter 8 may include a second filter frame 81 detachably fixed to the mounting body 21, and a second filter body 83 fixed to the second filter frame 81 and inserted into the mounting space 211.

The first filter 7 and the second filter 8 may be arranged to filter foreign matters of the same size, or may be arranged to filter foreign matters of different sizes. When the first filter 7 and the second filter 8 are arranged to filter the foreign matters of the different sizes, it is preferable that the second filter 8 is disposed to filter foreign matters of a size smaller than a size of the foreign matters filtered by the first filter 7. This is to minimize an amount of fine dusts discharged to an indoor space.

As shown in FIG. 2, the display 3 may include a display panel 37 exposed to the outside of the housing 1 through the cover through-hole 155, a display housing 31 to which the display panel 37 is fixed, and a housing fastening portion (or housing fastening extension) 35 for fixing the display housing 31 to the wall 19 or the interior of the second chamber S2 (an inner circumferential face of the housing and the like).

The display panel 37 is for displaying information associated with an operation of the cleaning appliance 100, and an LCD panel may be an example of the display panel 37. The information associated with the operation of the cleaning appliance may include a user selectable control command, information on whether cleaning of the filters 7 and 8 is necessary, information on whether the motor 54 disposed in the fan is abnormal, information on whether the battery needs to be charged, and the like as examples thereof.

Whether the cleaning of the filters 7 and 8 is necessary and whether the motor 54 is abnormal may be determined using a pressure sensor for sensing an internal pressure of the second chamber. That is, whether the cleaning of the filters 7 and 8 is necessary and whether the motor 54 is abnormal may be determined by comparing, by a controller, the internal pressure of the second chamber transmitted by the pressure sensor after the power is supplied to the motor 54 with a preset reference value. The controller may be disposed to determine that the motor is broken when the internal pressure of the second chamber is equal to or less than a preset first reference value, determine that the cleaning of the filter is necessary when the internal pressure of the second chamber is greater than the first reference value and less than a second reference value, and determine that the filter and the motor are in a normal state when the internal pressure of the second chamber is equal to or greater than the second reference value. In one example, the display panel 37 may be disposed as a touch panel capable of displaying not only the information but also the control command.

Because the display panel 37 is exposed to the outside of the housing through the cover through-hole 155, the display panel 37 may have the same shape as that of the cover through-hole 155.

The display housing 31 is fixed to the second chamber S2 through the housing fastening portion 35 to provide a space in which the display panel 37 is installed. The display housing 31 may be formed in a shape of a cylinder inserted into the filter body through-hole 711 and the cover through-hole 155.

A bottom face of the display housing 31 may be located above the casing exhaust hole 513. In this case, a support body communicating hole for flowing at least a portion of the air discharged from the casing exhaust hole 513 into the support body 313 may be defined in the bottom face of the display housing 31. Further, a filter communicating hole 33 for guiding the air flowed into the support body communicating hole to the first filter body 71 may be defined in a circumferential face of a support body 313.

The display housing 31 may include a panel mounting portion (or panel mounting region) 317 defined in a face facing the cover through-hole 151 of a space provided by the support body 313 to provide a space in which the display panel 317 is mounted. The panel mounting portion 317 may be defined as a groove in which one face (a face exposed to the outside of the housing through the cover through-hole) of the support body 313 is concavely bent, or a through-hole penetrating the support body 313 to be connected to the support body communicating hole.

The cleaning appliance 100 may further include a display cover 319 fixed to the support body 313 and positioned above the display panel 37 for protection of the display panel 37. The display cover 319 is preferably made of a transparent material.

The housing fastening portion 35 is means for detachably fixing the support body 313 to the wall 19 or the inner circumferential face of the second space S2, and FIG. 2 illustrates a case in which the housing fastening portion 35 fixes the support body 313 to the wall 19. The housing fastening portion 35 may include a boss 351 disposed on the wall 19, a flange 353 disposed on the support body 313, and a bolt for fixing the flange to the boss. An operation procedure of the cleaning appliance 100 having the above-described structure is as follows. As shown in FIG. 7, when the power is supplied to the motor 54 and the impeller 57 rotates, the air is flowed into the first separated chamber 41a through the intake pipe 111 and the intake hole 113. The intake pipe 111 includes a housing guide 115 for allowing the air discharged from the intake hole 113 to flow into a circumferential face of the first separated chamber 41a in a tangential direction. Therefore, the air flowed into the first separated chamber 41a will rotate along the circumferential face of the first separated chamber 41a.

When the air rotates inside the first separated chamber 41a, the foreign matters in the air will be flowed to the circumferential face of the first separated chamber 41a by the centrifugal force and then to the lower cover 18 disposed on the bottom face of the housing by gravity, and the air will flow through the through-hole 413 to the second separated chamber 41b.

The air flowed to the second separated chamber 41b will flow to the flow path body 421 through the inlet 423, and the air flowed into the flow path body 421 will flow cyclonically while passing through the air flow forming portion 425. When the cyclone flow occurs in the flow path body 421, the foreign matters contained in the air will flow to the circumferential face of the flow path body 421 by the centrifugal force and then be discharged to the storage space 419 by gravity. Further, the air will be discharged out of the housing 1 through the discharge tube 424, the communicating hole 25, the casing intake hole 511, the casing exhaust hole 513, the filter communicating hole 33, the body second through-hole 733, and the exhaust hole 153.

As described above, a discharge flow path is formed in the cleaning appliance 100 by the discharge pipe 424, the communicating hole 25, the casing intake hole 511, the casing exhaust hole 513, the filter communicating hole 33, the body second through-hole 733, and the exhaust hole 153. Because the discharge flow path is in a state in which bending is minimized, the cleaning appliance 100 may minimize a flow path resistance of the air flowed by the fan 5.

The foreign matters stored in the storage space 419 and the first separated chamber 41a are discharged to the outside of the housing 1 when the lower cover 18 opens the housing outlet 17. The first filter 7 is detachable from the housing 1 by opening the housing cover 152, and the second filter 8 is detachable from the housing 1 by withdrawing the separator 4 from the housing 1. FIG. 8 illustrates a different embodiment of a cleaning appliance. a structure of the cleaning appliance 100 according to the present embodiment may be the same as that of the cleaning appliance of FIGS. 1 to 7 except for the fan 5 and the display 3.

The fan 5 in the present embodiment may include the casing 51 in which the casing intake hole 511 and the casing exhaust hole 513 are defined, the impeller 57 rotatably disposed inside the casing and positioned between the casing intake hole 511 and the casing exhaust hole 513, the motor 54 for rotating the impeller, and the casing cover 59 disposed to form a rear face of the casing. Because the casing 51, the impeller 57, and the motor 54 have been described in the embodiments of FIGS. 1 to 7, detailed descriptions thereof will be omitted. The casing cover 59 may be fixed to the casing 51 or may be fixed to the wall 19, and may be fixed to an inner circumferential face of the housing 1 to be located in the second space S2. The casing cover 59 is disposed to form a rear face of the fan 5.

The casing 51 and the casing cover 59 may be coupled to each other to form one chamber. That is, the casing 51 may be disposed as a cylinder with an open top face, and the casing cover 59 may be disposed as a cylinder with an open bottom face.

The casing cover 59 may be fixed to the casing 51, the wall 19, or the inner circumferential face of the housing through a cover support 591. FIG. 8 illustrates an example in which the cover support 591 is disposed to fix the casing cover 59 to the wall 19.
