The present invention relates to a cleaner, and more particularly, to a vacuum cleaner in which a longitudinal axis of a suction part and an axis of a cyclone flow are disposed to be perpendicular to each other.
In general, a cleaner refers to an electrical appliance that draws in small garbage or dust by sucking air using electricity and fills a dust bin provided in a product with the garbage or dust. Such a cleaner is generally called a vacuum cleaner.
The cleaners may be classified into a manual cleaner which is moved directly by a user to perform a cleaning operation, and an automatic cleaner which performs a cleaning operation while autonomously traveling. Depending on the shape of the cleaner, the manual cleaners may be classified into a canister cleaner, an upright cleaner, a handy cleaner, a stick cleaner, and the like.
The canister cleaners were widely used in the past as household cleaners. However, recently, there is an increasing tendency to use the handy cleaner and the stick cleaner in which a dust bin and a cleaner main body are integrally provided to improve convenience of use.
In the case of the canister cleaner, a main body and a suction port are connected by a rubber hose or pipe, and in some instances, the canister cleaner may be used in a state in which a brush is fitted into the suction port.
The handy cleaner (hand vacuum cleaner) has maximized portability and is light in weight. However, because the handy cleaner has a short length, there may be a limitation to a cleaning region. Therefore, the handy cleaner is used to clean a local place such as a desk, a sofa, or an interior of a vehicle.
A user may use the stick cleaner while standing and thus may perform a cleaning operation without bending his/her waist. Therefore, the stick cleaner is advantageous for the user to clean a wide region while moving in the region. The handy cleaner may be used to clean a narrow space, whereas the stick cleaner may be used to clean a wide space and also used to a high place that the user's hand cannot reach. Recently, modularized stick cleaners are provided, such that types of cleaners are actively changed and used to clean various places.
There is a vacuum cleaner having a cyclone separation device in the related art related to the handy cleaner or the stick cleaner. In the cleaner in the related art, a cylindrical dust bin having a vertical axis is provided, and a plurality of cyclone parts each having a vertical axis is disposed in the dust bin. The air introduced into the dust bin is separated from dust by the cyclone part, and the separated dust is collected at a lower portion of the dust bin.
To increase an internal space of the dust bin in the related art, a diameter needs to be increased in a radial direction with respect to the vertical axis, or a length needs to be increased in a direction of the vertical axis. One of the two methods, which increases the length of the dust bin, is commonly used to smoothly generate a cyclone flow. However, the increase in length of the dust bin causes a problem in which it is impossible to clean a lower gap of a sofa by lowering an angle of the cleaner.
An object to be achieved by the present invention is to provide a cleaner that may easily clean a narrow gap by lowering a use angle of the cleaner even though an internal space of a dust bin is increased by changing a length of the dust bin in an axial direction instead of a radial direction of the dust bin.
Another object of the present invention is to provide a cleaner that distinguishes sucked pieces of dust for each size, separately collects the pieces of dust, and discards the collected pieces of dust for each size in order to prevent fine dust from scattering.
Technical problems of the present invention are not limited to the aforementioned technical problems, and other technical problems, which are not mentioned above, may be clearly understood by those skilled in the art from the following descriptions.
To achieve the above-mentioned objects, a cleaner according to an embodiment of the present invention includes: a dust bin including an inlet port formed at one side thereof, a discharge port formed at the other side thereof, and a cyclone part provided therein and configured to generate a cyclone flow; and a motor part configured to communicate with the dust bin and generate a flow of air in the dust bin, in which the dust bin includes: a casing having the inlet port and the discharge port; a separation wall configured to divide an internal space of the casing; a first dust storage part configured to communicate with the inlet port in the internal space; a second dust storage part configured to communicate with the discharge port in the internal space; and a communication hole formed in the separation wall and configured to allow the first dust storage part and the second dust storage part to communicate with each other.
The cleaner may further include: a suction part configured to communicate with the inlet port and elongated in one direction, in which the cyclone part includes an axis of a cyclone flow that is perpendicular to a longitudinal axis of the suction part and parallel to the ground surface.
The inlet port may be disposed at a lateral side of the suction part.
The cleaner of may further include: a suction part configured to communicate with the inlet port, in which the cyclone part is disposed below the suction part.
The separation wall may divide the internal space of the casing based on a straight line A1 passing through the inlet port and the discharge port so that the first dust storage part is disposed at one side and the second dust storage part is disposed at the other side.
The separation wall may be disposed in parallel with a direction in which air is introduced into the inlet port.
The cyclone part may include a first cyclone disposed in the first dust storage part and having a cylindrical shape.
The cyclone part may further include a cyclone filter disposed in the communication hole.
The cyclone part may further include a second cyclone disposed in the second dust storage part.
The cyclone part may further include a compression plate disposed in an opening portion of the first dust storage part.
To achieve the above-mentioned objects, a cleaner according to another embodiment of the present invention includes: a suction part elongated in one direction; a dust bin including an inlet port configured to communicate with the suction part and formed at one side thereof, a discharge port formed at the other side thereof, and a cyclone part configured to generate a cyclone flow; and a motor part configured to communicate with the discharge port of the dust bin and generate a flow of air in the dust bin, in which a longitudinal axis of the suction part intersects an axis of a cyclone flow in the cyclone part.
Other detailed matters of the exemplary embodiment are included in the detailed description and the drawings.
The cleaner of the present invention may have one or more of the following effects.
First, the axis of the cyclone flow intersects the longitudinal axis of the suction part and disposed in parallel with the ground surface. Therefore, even the increase in length of the dust bin does not affect the height of the cleaner, such that the use angle of the cleaner may be sufficiently decreased, which makes it possible to clean a lower region such as a gap below a sofa.
Second, based on the separation wall, larger dust is collected in the first dust storage part, and smaller dust is collected in the second dust storage part, such that the pieces of dust may be collected while being distinguished depending on sizes of the pieces of dust, thereby preventing the fine dust from scattering.
Third, the compression plate is provided to compress the dust collected in the first dust storage part, which may provide an effect of collecting a larger amount of dust in a limited space.
The effects of the present invention are not limited to the aforementioned effects, and other effects, which are not mentioned above, will be clearly understood by those skilled in the art from the claims.

With reference to
A direction of one side, at which the suction part 10 is positioned, is defined as a forward direction based on a longitudinal axis A1 of the suction part 10, and a direction of the other side, at which a motor part 20 to be described below is positioned, is defined as a rearward direction. Based on the main body 2 illustrated in
An external shape of the main body 2 is defined by a housing 3.
The housing 3 has a handle 40.
The suction part 10 is coupled to a front side of the housing 3.
The dust bin 60 is coupled to the front side of the housing 3. An opening portion is formed in a coupling portion between the housing 3 and the dust bin 60, and the housing 3 and the dust bin 60 communicate with each other.
A power source part 50 is coupled to a lower portion of the housing 3.
The motor part 20 is coupled to an upper portion of the housing 3. The motor part 20 may be coupled to a rear upper portion of the housing 3.
The suction part 10 has a cylindrical shape opened therein and configured to suck the air containing dust. The suction part 10 may provide a suction flow path in which the air containing dust may flow. The air containing dust may be guided to the main body 2 through the suction part 10.
The suction part 10 communicates with an inlet port 311 of a cyclone part 30. The air sucked by a nozzle passes through the suction part 10 and is introduced into the cyclone part 30 through the inlet port 311.
The main body 2 may further include the motor part 20, the cyclone part 30, the handle 40, and the power source part 50.
In this case, the motor part 20 is configured to generate a flow of air (i.e., gas flow) so that the air containing dust may be introduced into the suction part 10. The motor part 20 may include a motor housing 20, and a suction motor (not illustrated) accommodated in the motor housing 20.
The suction motor (not illustrated) may include a motor shaft (not illustrated), and an impeller connected to the motor shaft and configured to rotate.
The suction motor (not illustrated) may be a brushless DC (BLDC) motor. The BLDC motor is a DC motor having no brush. Because the BLDC motor does not have a brush that is an abrasive component, the BLDC motor advantageously generates less mechanical noise and rotational noise without a problem with a high-speed rotation.
The motor part 20 is disposed on the longitudinal axis A1 of the suction part. A center of gravity of the motor part 20 is disposed on the longitudinal axis A1 of the suction part.
This arrangement may minimize the moment of force generated on the cleaner 1. More specifically, the main body 2 of the cleaner may be defined as a single rigid body. The air is introduced at a portion closer to the upper side based on the cleaner main body 2. In this case, if an air discharge port is formed at another position, an air introduction direction and an air discharge direction are different from each other, which may cause the moment of force, and the cleaner may rotate in one direction. As a result, a user may feel discomfort when operating the cleaner 1. However, in the cleaner 1 according to the present invention, the motor part 20 is disposed on the longitudinal axis A1 of the suction part, which may minimize the moment of force to be generated on the cleaner 1 and facilitate the operation of the cleaner 1.
The main body 2 may further include the dust bin 60 to store the dust separated by the cyclone part 30.
The inlet port 311 is provided at one side of the dust bin 60, a discharge port 331 is provided at the other side of the dust bin 60, and the cyclone part 30 is provided in the dust bin 60 and generates a cyclone flow.
The dust bin 60 includes a cylindrical casing 610. The casing 610 has the inlet port 311 through which the air is introduced into the dust bin 60, and the discharge port 331 through which the air is discharged to the outside of the dust bin 60.
With reference to
The inlet port 311 and the discharge port 331 are provided in a circumferential direction of the dust bin 60. The inlet port 311 introduces the dust in the circumferential direction of the dust bin 60, such that the introduced air is subjected to a cyclone flow along an inner peripheral surface of the dust bin 60 or an outer peripheral surface of a cyclone filter 350.
A longitudinal axis of the inlet port 311 and a longitudinal axis of the discharge port 331 may be coaxially disposed. This defines a straight line A1 passing through the inlet port and the discharge port. The straight line passing through the inlet port and the discharge port 331 may be coaxial with the longitudinal axis A1 of the suction part.
An internal space of the casing 610 is divided into a first dust storage part 630 and a second dust storage part 640 by a separation wall 620.
The first dust storage part 630 is one of the internal spaces of the casing 610 and communicates with the inlet port 311.
With reference to
The first dust storage part 630 may have a cylindrical shape.
One end of the first dust storage part 630 is closed by a separating plate, and a first opening portion 631 is formed at the other end of the first dust storage part 630. The pieces of dust, which settle in the first dust storage part 630, are discharged to the outside through the first opening portion 631.
A first cap 632 is rotatably disposed in the first opening portion 631 of the first dust storage part 630. The first cap 632 closes the first opening portion 631 while the cleaner 1 operates. The first cap 632 opens the first opening portion 631 after the cleaner 1 operates, which may remove the dust settling in the first dust storage part 630.
The first cap 632 is a constituent element that selectively opens or closes the first opening portion 631. The first cap 632 covers the first opening portion 631.
A hinge is disposed at one side of the first cap 632, and a hook is disposed at the other side of the first cap 632. With reference to
A compression member 650 may be disposed on the first cap 632. The compression member 650 will be described below.
The second dust storage part 640 is one of the internal spaces of the casing 610 and communicates with the discharge port 331. With reference to
The second dust storage part 640 may have a cylindrical shape.
One end of the second dust storage part 640 is closed by the separating plate, and a second opening portion 641 is formed at the other end of the second dust storage part 640. The pieces of dust, which settle in the second dust storage part 640, are discharged to the outside through the second opening portion 641.
A second cap 642 is a constituent element that selectively opens or closes the second opening portion 641. The second cap 642 covers the second opening portion 641.
A hinge is disposed at one side of the second cap 642, and a hook is disposed at the other side of the second cap 642. With reference to
The first opening portion 631 and the second opening portion 641 are opposite to each other. With reference to
The separation wall 620 is a constituent element that divides the internal space of the dust bin 60 into the first dust storage part 630 and the second dust storage part 640. At least a part of the first cyclone 310 penetrates the separation wall 620. The separation wall 620 includes a first separation wall 620a and a second separation wall 620b.
The first separation wall 620a extends radially outward from an outer peripheral surface of the first cyclone 310. The second separation wall 620b extends radially inward from an inner peripheral surface of the first cyclone 310. The second separation wall 620b may extend radially outward from the outer peripheral surface of the first cyclone 310.
The first separation wall 620a extends radially outward from a lateral side of the first cyclone 310. The first separation wall 620a separates the first dust storage part 630 and the second dust storage part 640.
The second separation wall 620b extends radially inward or radially outward from an end of the first cyclone 310. The second separation wall 620b closes one side end of the first cyclone 310.
At least a part of the first cyclone 310 is inserted into the first separation wall 620a. One side of the first cyclone 310 is closed by the second separation wall 620b.
The first cyclone 310 is disposed to be spaced apart from the dust bin 60. The separation wall 620 is supported by the dust bin 60 and supports the first cyclone 310.
The separation wall 620 divides the internal space of the casing 610 so that the first dust storage part is disposed at one side and the second dust storage part 640 is disposed at the other side based on the straight line A1 passing through the inlet port and the discharge port. The straight line A1 passing through the inlet port and the discharge port is coaxial with the longitudinal axis A1 of the suction part. In this arrangement, the first dust storage part 630 and the second dust storage part 640 are disposed in the spaces spaced apart from each other at two opposite sides of the flow of the introduced air, such that the large dust and the small dust may be easily stored in the different spaces.
The separation wall 620 is disposed in parallel with a direction in which the air is introduced into the inlet port 311. In other words, the separation wall 620 is disposed in parallel with the straight line A1 passing through the inlet port and the discharge port. The separation wall 620 separates the first dust storage part 630 and the second dust storage part 640 at the left and right sides when viewed from the front side. With this arrangement, the large dust and the small dust may be easily stored in the different spaces at two opposite sides of the flow of the introduced air.
The separation wall 620 is disposed to be perpendicular to an axis A2 of a first cyclone flow or an axis A3 of a second cyclone flow. In other words, the separation wall 620 extends in a forward/rearward direction.
With reference to
The communication hole 621 allows the first dust storage part 630 and the second dust storage part 640 to communicate with each other.
The communication hole 621 is formed through one side of the separation wall 620. The communication hole 621 is disposed in the first cyclone 310.
The communication hole 621 is disposed to be closer to an upper side of the separation wall 620. With reference to
In case that the separation wall 620 includes the first separation wall 620a and the second separation wall 620b, the communication hole 621 is formed in the second separation wall 620b.
The cyclone filter 350 is disposed in the communication hole 621.
The cyclone part 30 may communicate with the suction part 10. The cyclone part 30 adopts a principle of a dust collector using a centrifugal force to separate the dust sucked into the main body 2 through the suction part 10.
For example, the cyclone part 30 may include the first cyclone 310 capable of separating dust by using a cyclone flow. The first cyclone 310 may communicate with the suction part 10. The air and dust introduced through the suction part 10 spirally flows along an inner peripheral surface of the first cyclone 310. The axis A2 of the cyclone flow in the first cyclone 310 may extend to left and right lateral sides.
The cyclone part 30 may further include the second cyclone 330 configured to separate dust again from the air discharged from the first cyclone 310. The second cyclone 330 may include a plurality of cyclone bodies disposed in parallel. The air discharged from the first cyclone 310 may be separated and pass through the plurality of cyclone bodies.
In this case, the axis A3 of the cyclone flow in the second cyclone 330 may also extend to the left and right lateral sides. The axis A2 of the cyclone flow in the first cyclone 310 and the axis A3 of the cyclone flow in the second cyclone 330 are disposed in parallel.
The axes A2 and A3 of the cyclone flows may be disposed to be perpendicular to the longitudinal axis A1 of the suction part. More specifically, the axes A2 and A3 of the cyclone flows may be disposed to be perpendicular to both the longitudinal axis A1 of the suction part and a longitudinal axis A4 of the handle. With reference to
The cyclone part 30 may be disposed below the suction part 10. The suction part 10 includes pieces of dust with various sizes. If the cyclone part 30 is disposed above the suction part 10, there is a problem in that very large dust may settle between the cyclone part 30 and the suction part 10, the very large dust remains between the cyclone part 30 and the suction part 10 without merging into the cyclone flow. Therefore, the cyclone part 30 is disposed below the suction part 10, such that the dust is smoothly introduced into the cyclone part 30.
The first cyclone 310 and the second cyclone 330 are disposed in the spaces spaced apart from each other with the separation wall 620 interposed therebetween.
The first cyclone 310 is disposed at the right side of the separation wall 620 when viewed from the front side. The first cyclone 310 is disposed in the first dust storage part 630.
The first cyclone 310 has a cylindrical shape. The first cyclone 310 has a cylindrical shape having a center disposed on the axis A2 of the first cyclone flow. The axis A2 of the first cyclone flow is parallel to a central axis of the dust bin 60.
The axis A2 of the first cyclone flow is disposed in a leftward/rightward direction. More specifically, the axis A2 of the first cyclone flow is parallel to the ground surface. Therefore, the introduced air turns along the axis A2 of the first cyclone flow and is accumulated on a bottom of the first cyclone 310.
The inlet port 311 is provided at one side of the first cyclone 310. The inlet port 311 connects the suction part 10 and the first cyclone 310. A front end of the inlet port 311 communicates with the suction part 10, and a rear end of the inlet port 311 communicates with the first cyclone 310.
The inlet port 311 is disposed to be closer to one side of the first cyclone 310. More specifically, with reference to
At least a part of the first cyclone 310 is disposed and formed through the separation wall 620. In other words, the separation wall 620 extends outward from the outer peripheral surface of the first cyclone 310. Because at least a part of the first cyclone 310 is formed through the separation wall 620, a stroke distance of a compression plate 651 may further increase, and a large amount of large dust present in the first dust storage part 630 may be compressed.
The first cyclone 310 is disposed at an upper side of the first dust storage part 630. Therefore, the pieces of dust are accumulated on a lower space of the first cyclone 310.
The inlet port 311 is disposed in a radial direction of the longitudinal axis A1 of the suction part and disposed in a radial direction of the axis of the cyclone flow. In other words, the inlet port 311 is disposed at an intersection point between the longitudinal axis A1 of the suction part and the axis of the cyclone flow.
The axis A2 of the first cyclone flow intersects the longitudinal axis A1 of the suction part and is perpendicular to the longitudinal axis A4 of the handle. More specifically, the axis A2 of the first cyclone flow is perpendicular to both the longitudinal axis A1 of the suction part and the longitudinal axis A4 of the handle.
The inlet port 311 is disposed on the longitudinal axis A1 of the suction part. With the above-mentioned arrangement, the air is introduced into the first cyclone 310 while having minimum resistance. Therefore, an active cyclone flow may be generated in the first cyclone 310.
In the first cyclone 310, the air rotates around the cyclone filter 350.
One side of the first cyclone 310 is closed, and other side of the first cyclone 310 is opened. With reference to
The axis A2 of the first cyclone flow intersects the longitudinal axis A1 of the suction part. More specifically, the axis A2 of the first cyclone flow is perpendicular to the longitudinal axis A1 of the suction part and parallel to the ground surface. In other words, the axis A2 of the first cyclone flow is perpendicular to the straight line passing through the inlet port 311 and the discharge port. The longitudinal axis A1 of the suction part is coincident with the circumferential direction of the first cyclone 310. Therefore, the dust introduced from the suction part 10 generates the cyclone flow in the first cyclone 310. The dust may be quickly separated from the air by the gravity and the centrifugal force made by the cyclone flow.
The cyclone part 30 may be disposed below the suction part 10.
The second cyclone 330 may be disposed at the left side of the separation wall 620 when viewed from the front side. The second cyclone 330 is disposed in the second dust storage part 640.
The second cyclone 330 has a cylindrical shape. The second cyclone 330 has a cylindrical shape having a center disposed on the axis A3 of the second cyclone flow. The axis A3 of the second cyclone flow is parallel to the central axis of the dust bin 60.
The second cyclone includes an outer tube 332 and an inner tube 333. A flow in the second cyclone 330 may be formed between the outer tube 332 and the inner tube 333.
With reference to
An end of the outer tube 332 may have a conical shape having a diameter that gradually decreases.
The second cyclone 330 includes blades 334. The blade 334 assists in generating the cyclone flow in the second cyclone 330.
The blade 334 is formed between the outer tube 332 and the inner tube 333 of the second cyclone 330. The blade 334 generates a swirl flow in one direction. The blade 334 may generate a cyclone flow counterclockwise when viewed from the left side.
The dust may be quickly separated from the air by the gravity and the centrifugal force made by the cyclone flow.
The air is subjected to a cyclone flow in a space between the outer tube 332 and the inner tube 333. The air, which is subjected to the cyclone flow, may be discharged to the outside through the inner tube 333. With reference to
The second cyclone 330 may be provided as a plurality of second cyclones 330 disposed along the outer peripheral surface of the first cyclone 310. With reference to
The axis A3 of the second cyclone flow may be disposed in the leftward/rightward direction. More specifically, the axis A2 of the first cyclone flow is parallel to the ground surface. Therefore, the introduced air turns along the axis A3 of the second cyclone flow and is accumulated on a bottom of the second cyclone 330.
The discharge port 331 is provided at one side of the second dust storage part 640. The front end of the discharge port 331 communicates with the second dust storage part 640, and the rear end of the discharge port 331 communicates with the housing 3 or the motor part 20.
The discharge port 331 is provided in the outer peripheral surface of the dust bin 60 and discharges the air to the outside in the circumferential direction.
A direction in which the air is discharged from the discharge port 331 may be disposed in parallel with a direction in which the air is introduced into the inlet port 311. More specifically, the direction in which the air is discharged from the discharge port 331 may be coaxial with the direction in which the air is introduced into the inlet port 311.
The axis A3 of the second cyclone flow is perpendicular to the longitudinal axis A1 of the suction part and parallel to the ground surface. In other words, the axis A3 of the second cyclone flow is perpendicular to the straight line A1 passing through the inlet port and the discharge port.
The axis A3 of the second cyclone flow intersects the longitudinal axis A1 of the suction part and is perpendicular to the longitudinal axis A4 of the handle. More specifically, the axis A3 of the second cyclone flow is perpendicular to both the longitudinal axis A1 of the suction part and the longitudinal axis A4 of the handle.
With reference to
The cyclone filter 350 is disposed between the first cyclone 310 and the second cyclone 330. The cyclone filter 350 is disposed in the communication hole 621.
To this end, the cyclone filter 350 may include a mesh portion having a plurality of holes. The mesh portion may be made of a metallic material. However, the present invention is not limited thereto.
At least a part of the cyclone filter 350 protrudes in the direction of the first dust storage part 630. The cyclone filter 350 may have a cup shape protruding in the direction of the first dust storage part 630.
If the cyclone filter 350 protrudes in the direction of the first dust storage part 630, there is a problem in that the filtered-out dust is accumulated in the cyclone filter 350. On the contrary, the cyclone filter 350 according to the present invention protrudes in the direction of the first dust storage part 630, such that the dust is scattered again by the air in the cyclone flow even though a part of the dust settles in the cyclone filter 350. As a result, the dust does not settle in the cyclone filter 350, which may maintain a cleanliness state.
In the first cyclone 310, the air rotates around the cyclone filter 350. Apart of the air rotates along the outer peripheral surface of the cyclone filter 350, and the remaining air may flow to the second dust storage part 640 while passing through the cyclone filter 350.
The compression member 650 is a constituent element disposed in the first dust storage part 630 and configured to compress the large dust settling in the first dust storage part 630.
With reference to
The compression plate 651 is disposed in the first cap 632. The first cap 632 may have a depressed portion formed at position facing the first opening portion 631. At least a part of the compression plate 651 is inserted into the depressed portion of the first cap 632. The compression plate 651 may be installed in the first cap 632 and disposed on the first opening portion 631, and the compression plate 651 may close the first opening portion 631.
The compression plate 651 is formed in a cross-sectional shape of the first dust storage part. The first opening portion 631 has a circular cross-sectional area when viewed from the right side. The compression plate 651 may be formed as a circular plate along a shape of the cross-sectional area of the first opening portion 631. With reference to
With reference to
The compression plate guide bar 652 is coupled to one side of the compression plate 651. With reference to
The compression plate guide bar 652 is provided in the form of a cantilevered beam.
The compression plate guide bar 652 penetrates the first cap 632. The first cap 632 has a through-hole into which the compression plate guide bar 652 is inserted. The compression plate guide bar 652 may move while passing through the through-hole.
One end of the compression plate guide bar 652 is coupled to a guide plate, and the other end of the compression plate guide bar 652 is connected to the lever 660. When the lever 660 moves in a second direction, the compression plate guide bar 652 moves along the lever 660, and the guide plate is compressed.
