Description

Cleaning device

Technical Field

The present application relates to a cleaning device.

Background

The cleaning device is a device that sucks dust or foreign matter to clean a room. Conventional cleaning devices generally include: a housing having an air inlet and an exhaust portion (exhaust); a fan for making the air flowing into the air inlet flow to the air exhaust part; a separating member for separating foreign matters from air flowing through the fan; a filter between the separating member and the fan to filter foreign matters from air passing through the separating member; and a handle disposed on the housing.

The conventional cleaning device has the following disadvantages: the flow path between the air passing through the fan and the exhaust portion is complicated (flow path resistance is high) so that the output of the fan should be maintained higher than necessary. Further, although the conventional cleaning device has an input unit for inputting a control command, there is no display for informing a user of information associated with the operation of the cleaning device.

Detailed Description

Hereinafter, preferred embodiments of the cleaning device will be described in detail with reference to the accompanying drawings. The configurations or methods for controlling devices described below are merely for describing embodiments of the present application and are not intended to limit the scope of the present application. Furthermore, like reference numerals designate like components throughout the specification.

Fig. 1 shows an example of a cleaning device 100. The cleaning device 100 may include: a housing 1 formed in the following form: a cylinder having a hollow portion defined therein, an air inlet 11 formed on the housing 1, an air discharge portion 15 defined in the housing 1; a fan 5 disposed inside the housing 1 to cause air to flow from the air inlet 11 to the air outlet 15; a separating member 4 guiding air flowing into the air inlet 11 to the fan 5 and separating foreign substances from the air using centrifugal force; and a display 3 for displaying information associated with the cleaning device.

A handle 6 is provided on the housing 1. In the space provided by the circumferential surface of the housing 1, the handle 6 may be positioned at a point symmetrical (180 degrees apart) to the point at which the air inlet 11 is located.

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

The air inlet 11 is provided on a circumferential surface of the housing 1 to allow outside air to flow into the first space S1. The intake port 11 may include an intake port 113 defined to penetrate a circumferential surface of the housing 1, and an intake pipe 111 extending from the intake port 113 in a direction away from the center of the housing 1 (a direction away from the handle, a Y-axis direction). Although not shown in the drawings, the cleaning device of the present disclosure may further include an extension pipe detachably provided on the air inlet pipe 111, and a nozzle provided at a free end of the extension pipe to allow foreign matter to flow into the extension pipe.

As shown in fig. 1, a case outlet 17 for discharging foreign matter stored in the case 1 to the outside is also defined in the bottom surface of the case 1 (one surface of the case opposite to the surface in which the exhaust portion is defined). The housing outlet 17 is opened and closed by a lower cover 18. The lower cover 18 may be pivotally fixed to the housing 1.

The exhaust part 15 may include a case through hole 151 defined through the top surface of the case 1 to communicate the inside of the second space S2 with the outside of the case 1, a case cover 152 for closing the case through hole, a cover through hole 155 defined through the case cover 152, and an exhaust hole 153 through the case cover 152 to exhaust air in the second space S2 therethrough.

The case cover 152 may be formed in any shape as long as the case through-hole 151 can be closed. The drawings show an example of a disc-shaped housing cover for closing a column-shaped housing.

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

A first filter 7 for filtering air flowing from the fan 5 to the exhaust hole 153 may be provided 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 under the case 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 communicating with the cover through hole 155 may be defined at the center of the first filter body 71, and a body first through hole 731 communicating with the filter body through hole 711 may be provided at the center of the first filter frame 73. Further, a body second through hole 733 for supplying 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.

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

As shown in fig. 2, the mounting portion 2 may be disposed inside the wall through hole S3. The mounting portion 2 serves to provide a mounting space 211 in which the second filter 8 is mounted. The mounting portion 2 may be provided 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 provided in a cylindrical shape or a polygonal 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 the top surface of the mounting body 21, and a plurality of communication holes 25 for communicating the mounting space 211 with the first space S1 may be defined in the bottom surface 23 of the mounting body 21.

The mounting body 21 may be detachably coupled to the housing wall 19 by a body fastening portion 27. As shown in fig. 2, the body fastening portion 27 may include a protrusion 271 provided on an outer circumferential surface 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 separate piece 4 to the housing outlet 17, the mounting body 21 and the second filter 8 can be drawn out of the housing 1 together with the separate piece 4. When the mounting body 21 and the second filter 8 are withdrawn from the housing 1, the user can detach the second filter 8 from the mounting body 21. Therefore, the cleaning device 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 such that air in the first space S1 flows to the exhaust hole 153 through the communication hole 25. Further, the separating piece 4 is a flow path formed in the first space S1 to guide the air flowing into the air intake 11 to the communication hole 25. Foreign substances (such as dust) contained in the air are separated from the air by centrifugal force while flowing to the fan 5 along a flow path provided by the separating member 4, and the separating member 4 has the following specific structure.

The separating member 4 includes a chamber forming portion 41 for dividing the first space S1 into a first separating chamber 41a and a second separating chamber 41b, and a cyclone forming portion 42 for supplying air in the second separating chamber 41b to the fan 5. The cyclone forming portion 42 serves to provide centrifugal force to foreign substances contained in the air by rotating the air flowing toward 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 surface 23 of the mounting body, and the other end of the chamber forming portion 41 may include: a chamber body 411 separated from contact with the lower cover 18; and a separation chamber wall 417 for separating the second separation chamber 41b formed in the separation chamber body into a separation space 418 and a storage space 419.

The separation chamber body 411 includes a plurality of through holes 413 that communicate the first separation chamber 41a and the separation space 418 with each other. Accordingly, the air flowing into the first separation chamber 41a through the air inlet 11 may be supplied to the separation space 418 through the through hole 413.

An outlet 415 is defined in a bottom surface of the separation chamber body 411 that contacts the lower cover 18. Accordingly, when the lower cover 18 opens the housing outlet 17, foreign matter stored in the storage space 419 may be discharged to the outside of the housing 1 through the outlet 415.

As shown in fig. 4, each cyclone forming portion 42 may have one end fixed to the bottom surface 23 of the mounting body and the other end including a flow path body 421 penetrating the separation chamber wall 417 and communicating with the storage space 419, each discharge pipe 424 has one end connected to the mounting space 211 and the other end located inside the flow path body 421, each inlet 423 is defined to penetrate the circumferential surface of the flow path body 421, and each airflow forming portion 425 forms a spiral flow path between the outer circumferential surface of the discharge pipe 424 and the inner circumferential surface of the flow path body. Each discharge pipe 424 may be provided as a pipe fixed to each communication hole 25. Each flow path body 421 may be provided as a tube fixed to the bottom surface 23 of the mounting body so as to surround each communication hole.

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

When the cyclone flow is generated in the flow path body 421, foreign substances contained in the air flow to the edge of the flow path (circumferential surface of the flow path body) due to centrifugal force, and then are 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 so that air flowing into the communication hole 25 flows toward the exhaust hole 153. The fan 5 may include: a housing 51 disposed in the wall through hole S3; an impeller 57 rotatably provided inside the housing; and a motor 54 fixed to the housing to rotate the impeller 57. The housing 51 may be provided in a hollow cylindrical shape. Further, a housing intake hole 511 and a housing exhaust hole 513 are defined in the housing 51. The case air intake holes 511 may be defined to guide air flowing through the communication holes 25 of the mounting portion into the case 51, and the case air exhaust holes 513 may be defined to exhaust air in the case 51 to the second space S2.

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

The impeller 57 is disposed to be located between the housing intake hole 511 and the housing 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 configured to receive electric power through a power source provided in the room, or may be configured to receive electric power through a battery 65 detachable from the housing 1. When the handle 6 is provided to include the handle body 61 protruding in a direction away from the intake port on the back surface (surface opposite to the surface on which the intake port is located) of the housing 1, the handle body 61 may include the battery housing 63 in which the battery 65 is detachably accommodated.

In one example, the second filter 8 is provided in the mounting body 21 for filtering foreign matter that is not removed by the separating member 4. As shown in fig. 6, the second filter 8 may include a second filter frame 81 detachably fixed to the installation body 21, and a second filter body 83 fixed to the second filter frame 81 and inserted into the installation space 211.

The first filter 7 and the second filter 8 may be arranged to filter the same-sized foreign matter, or may be arranged to filter different-sized foreign matter. When the first filter 7 and the second filter 8 are arranged to filter foreign matters of different sizes, it is preferable that the second filter 8 is provided to filter foreign matters of a size smaller than that of the foreign matters filtered by the first filter 7. This is to reduce the amount of fine dust discharged into the indoor space as much as possible.

As shown in fig. 2, the display 3 may include a display panel 37 exposed to the outside of the housing 1 through a 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 inside of the second chamber S2 (an inner circumferential surface of the housing, etc.).

The display panel 37 is for displaying information associated with the operation of the cleaning device 100, and an LCD panel may be an example of the display panel 37. The information associated with the operation of the cleaning device may include, for example, a control command selectable by a user, information about whether cleaning of the filters 7 and 8 is required, information about whether the motor 54 provided in the fan is abnormal, information about whether charging of the battery is required, and the like.

Whether cleaning of the filters 7 and 8 is required and whether the motor 54 is abnormal may be determined using a pressure sensor for sensing the internal pressure of the second chamber. That is, by comparing the internal pressure of the second chamber, which is transmitted by the pressure sensor, with a preset reference value by the controller after power is supplied to the motor 54, it can be determined whether cleaning of the filters 7 and 8 is required and whether the motor 54 is abnormal. The controller may be configured to determine that the motor is damaged when the internal pressure of the second chamber is equal to or less than a preset first reference value, determine that the filter needs to be cleaned 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 provided as a touch panel capable of displaying not only information but also control commands.

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

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

The bottom surface of the display housing 31 may be located above the housing vent 513. In this case, a support body communication hole is defined in the bottom surface of the display housing 31 for allowing at least a portion of the air discharged from the housing exhaust hole 513 to flow into the support body 313. Further, a filter communication hole 33 for guiding air flowing into the support body communication hole to the first filter body 71 is defined in the circumferential surface of the support body 313.

The display housing 31 may include panel mounting portions (or panel mounting regions) 317 respectively defined in faces of the space provided by the support body 313 facing the cover through-holes 151 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 of the support body 313 (a face exposed to the outside of the housing through the cover through-hole) is concavely curved, or as a through-hole penetrating the support body 313 to be connected to the support body communication hole.

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

The case fastening portion 35 is a member for detachably fixing the support body 313 to the wall 19 or the inner circumferential surface of the second space S2, and fig. 2 shows a case where the case fastening portion 35 fixes the support body 313 to the wall 19. The housing fastening portion 35 may include a boss 351 provided on the wall 19, a flange 353 provided on the support body 313, and bolts for fixing the flange to the boss. The operation procedure of the cleaning device 100 having the above-described structure is as follows. As shown in fig. 7, when power is supplied to the motor 54 and the impeller 57 is rotated, air flows into the first separation chamber 41a through the intake duct 111 and the intake hole 113. The intake duct 111 includes a housing guide 115 for allowing air discharged from the intake hole 113 to flow into the circumferential surface of the first separation chamber 41a in the tangential direction. Therefore, the air flowing into the first separation chamber 41a will rotate along the circumferential surface of the first separation chamber 41 a.

When the air rotates inside the first separation chamber 41a, foreign matter in the air will flow to the circumferential surface of the first separation chamber 41a by centrifugal force, and then to the lower cover 18 provided on the bottom surface of the housing by gravity, and the air will flow to the second separation chamber 41b through the through hole 413.

The air flowing toward the second separation chamber 41b will flow toward the flow path body 421 through the inlet 423, and the air flowing into the flow path body 421 will flow cyclonic while passing through the airflow forming portion 425. When a cyclone flow is generated in the flow path body 421, foreign substances contained in the air will flow to the circumferential surface of the flow path body 421 by centrifugal force, and then be discharged to the storage space 419 by gravity. Further, air will be discharged out of the housing 1 through the discharge pipe 424, the communication hole 25, the housing intake hole 511, the housing exhaust hole 513, the filter communication 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 device 100 through the discharge pipe 424, the communication hole 25, the housing intake hole 511, the housing exhaust hole 513, the filter communication hole 33, the body second through hole 733, and the exhaust hole 153. Since the discharge flow path is in a state where the curvature is minimized, the cleaning device 100 can reduce the flow path resistance of the air flowing via the fan 5 as much as possible.

When the lower cover 18 opens the housing outlet 17, foreign substances stored in the storage space 419 and the first separation chamber 41a are discharged to the outside of the housing 1. The first filter 7 can be detached from the housing 1 by opening the housing cover 152, and the second filter 8 can be detached from the housing 1 by withdrawing the separating member 4 from the housing 1. Fig. 8 shows a different embodiment of the cleaning device. The structure of the cleaning device 100 according to the present embodiment may be the same as that of the cleaning device of fig. 1 to 7 except for the fan 5 and the display 3.

The fan 5 in the present embodiment may include a housing 51 having a housing intake hole 511 and a housing exhaust hole 513 defined therein, an impeller 57 rotatably provided inside the housing and located between the housing intake hole 511 and the housing exhaust hole 513, a motor 54 for rotating the impeller, and a housing cover 59 provided to form a rear surface of the housing. Since the housing 51, the impeller 57, and the motor 54 have been described in the embodiment of fig. 1 to 7, detailed descriptions thereof will be omitted. The case cover 59 may be fixed to the case 51 or may be fixed to the wall 19, and may be fixed to the inner circumferential surface of the case 1 to be located in the second space S2. The housing cover 59 is provided to form the back surface of the fan 5.

The housing 51 and the housing cover 59 may be coupled to each other to form one chamber. That is, the housing 51 may be provided as a cylinder having an open top surface, and the housing cover 59 may be provided as a cylinder having an open bottom surface.

The housing cover 59 may be secured to the housing 51, the wall 19, or an inner circumferential surface of the housing by a cover support 591. Fig. 8 shows an example in which a cover support 591 is provided to secure the housing cover 59 to the wall 19. In this case, the cover support 591 may be provided as a boss 595 provided on the wall 19, a flange 597 provided on the housing cover 59, and bolts for interconnecting the boss and the flanges 595 and 597. The housing cover 59 may include a filter first communication hole 593 defined therein such that air discharged through the housing exhaust hole 513 may be discharged to the outside of the housing cover 59.

In one example, the display 3 in the present embodiment includes the display housing 31 inserted into the filter body through hole 711 and the cover through hole 155 and located above the housing cover 59, and the housing fastening portion 35 for fixing the display housing 31 to the second space S2. The display housing 31 may include a support body 313 in the form of a hollow cylinder. The display panel 37 provided on the display is fixed to the support body 313.
