In addition, an operation member 150 for opening/closing the cleaning machine 1 may be provided at the top end portion of the handle body 73.

Therefore, if the user holds the handle body 73, the user can naturally manipulate the operation member 150 with the thumb.

Hereinafter, the configuration of the cleaner 1 provided inside/outside the first casing 10 and the second casing 16 will be described in detail with reference to FIGS. 3 to 5.

First, referring to FIG. 3, a cross-section taken along line AA′ shown in FIG. 2 is shown. The sweeper 1 according to an embodiment of the present invention may further include a first housing cover 23 coupled to the first housing 10 To form the bottom surface of the first housing 10.

The first housing cover 23 may be configured in a disc shape and hinged to the first housing 10 to selectively open/close the bottom opening side of the first housing 10.

Therefore, if dust accumulates in the first housing 10, the user can open the first housing cover 23 to discharge the dust from the first housing 10.

In order to hinge the first housing cover 23 to the first housing 10, the hinge portion 232 is provided on the bottom side of the first housing 10, and the bottom cover connection hinge 101 connected to the hinge portion 232 may be provided on the first housing cover 23's edge.

The sweeper 1 according to an embodiment of the present invention may further include a second housing cover 26 coupled to the rear surface of the second housing 16.

The second housing cover 26 is configured in a disc shape to form the rear surface of the second housing 16, and the outer circumferential surface of the disc is configured in a cylindrical shape extending forward so as to be coupled to the second housing 16 The rear end of the circumferential surface.

In addition, a plurality of exhaust holes 261 penetrating through the second housing cover 26 are formed in the second housing cover 26, and the air in the second housing 16 can be discharged outward through the plurality of exhaust holes 261.

Meanwhile, the sweeper 1 according to an embodiment of the present invention uses the cyclone effect to separate dust from the air sucked in, and the related configuration will be described below.

First, a cylindrical chamber housing 43 smaller than the first housing 10 may be provided in the first housing 10. With the chamber housing 43, the internal space of the first housing 10 can be divided into a first chamber 431 outside the chamber housing 43 and a second chamber 433 inside the chamber housing 43.

A plurality of chamber housing perforations 435 may be formed in the circumferential surface of the chamber housing 43. And, the chamber housing perforation 435 may constitute a path through which the air in the first chamber 431 is filtered and flows into the second chamber 433.

The first cyclone effect occurs in the first chamber 431, and the second cyclone effect may occur in the second chamber 433.

Referring to FIG. 3 and FIG. 4 showing a cross section taken along line B-B' of FIG. 3, the following describes a configuration related to the first cyclone effect occurring in the first chamber 431.

First, the center of the air inlet 12 is provided so as to be inclined to the right or left within a specified range with respect to the longitudinal axis of the air intake pipe 31. Therefore, the air flowing into the first chamber 431 can flow along the The outer circumferential surface rotates naturally.

The air intake member 30 may further include an air intake pipe connection portion 32 that connects the air intake pipe 31 to the first housing 10, and a rotary guide 33 that guides air to the air inlet 12 may be installed at the air intake pipe connection portion 32 Inside.

The rotation guide 33 may be provided to connect the side surface closest to the longitudinal axis of the intake pipe in the portion where the intake port 12 is formed on the outer circumferential surface of the first housing 10 to the inner wall of the intake pipe connection portion 32 The inner wall in the oblique direction relative to the air inlet 12.

Therefore, a first cyclone effect in which air rotates along the outer circumferential surface of the chamber housing 43 occurs in the first chamber 431. When the air rotates, dust heavier than the air may fall to the bottom of the first chamber 431.

Thereafter, the air is filtered through the perforation 435 of the chamber housing, and then flows into the second chamber 433.

The following describes the configuration related to the second cyclone effect that occurs in the second chamber 433.

Although the following description is made with reference to FIG. 3, the details of the coupling can be further clearly understood by referring to FIG. 5, which is an exploded perspective view.

The sweeper 1 according to an embodiment of the present invention may further include a cyclone forming member 50 provided to the second chamber 433.

In addition, the cyclone forming member 50 may include a plurality of flow path bodies 51, each of which is configured to have a cylindrical shape with open top and bottom sides, the longitudinal axis of which is perpendicular to the first housing cover 23 or the ground, And has a lower portion configured in a conical shape, the diameter of which continuously decreases downward.

Each of the plurality of flow path bodies 51 forms a dust separation flow path 51a in which air flows by rotating around an axis perpendicular to the first housing cover 23 or the ground. Also, the rising pipe 53 may be provided in each of the plurality of flow path bodies 51, and the rising air flow is formed in the rising pipe 53 by the fan 60.

The riser 53 may be configured in a cylindrical shape whose top side and bottom side are open. Also, an inflow port 51b (or an open top side) for flowing air into the dust separation flow path 51a may be formed between the top surface of the flow path body 51 and the riser 53.

In addition, the blade 55 may be provided between the rising pipe 53 and the flow path body 51 to connect the outer circumference of the rising pipe 53 and the inner circumference of the flow path body 51 together.

The blade 55 is arranged to be inclined at a specified angle with respect to a plane parallel to the ground, and has a function of rotating air flowing into the inlet 51b.

In addition, a dust discharge port 51c formed as an open plane may be formed on the bottom side of each of the plurality of flow path bodies 51.

According to the configuration described above, in the cyclone forming member 50, the second cyclone effect occurs in such a manner that air flows into the inlet 51b and then descends by the blade 55 rotating along the dust separation flow path 51a. Thereafter, the air will rise along the riser 53.

In this way, the dust contained in the air cannot flow into the riser 53 due to its own weight, but is discharged outward from the flow path main body 51 through the dust discharge port 51c.

The plurality of flow path bodies 51 can be connected to each other through the connection plate 57. Also, the connecting plate 57 may be configured in a disc shape corresponding to the inner circumferential shape of the chamber housing 43.

A conical dust separation member 46 having open top and bottom sides may be provided on the bottom side of the connection plate 57. In addition, the dust separating member 46 has a function of storing the dust separated by the cyclone forming member 50.

In addition, the dust separating member 46 also has a function of preventing air in the first chamber 431 from being sucked into the dust discharge port 51c. For this, the top side of the dust separating member 46 is covered by the connecting plate 57 and the bottom side of the dust separating member 46 may be sealed by the first housing cover 23 and the annular sealing rib 233 provided on the top side of the first housing cover 23 .

Here, in order to ensure the airtightness of the bottom side of the dust separating member 46, it is preferable that the sealing rib 233 is formed of a flexible material.

In some implementations, the sweeper 1 according to an embodiment of the present invention may further include a partition 59 covering the top side of the second chamber 433, and the related configuration can be further understood with reference to FIGS. 3 and 4.

The partition 59 is provided above the chamber housing 43, and the bottom side of the partition 59 may be configured in a cup shape that can cover the top side of the second chamber 433.

A plurality of rising pipe insertion holes 591 may be formed in the bottom side of the partition 59 so as to be coupled with the protruding portions of the rising pipe 53, respectively.

The rising pipe 53 is provided in such a manner as to protrude upward from the top side of the flow path main body 51 by a predetermined length for allowing air to flow into the dust separation flow path 51a, and a specified portion of the protruding portion may be connected to the bottom surface of the partition 59 to form The riser is inserted into the hole 591.

A partition flange 593 extending a predetermined length in the circumferential direction may be formed on the top edge of the partition 59. The partition flange 593 is coupled to the partition support rib 102 in the first housing 10, thereby fixing the partition 59 to the first housing 10.

The air rising through the rising pipe 53 through the fan 60 may pass through the first filter 93 of the filter member 90 and then flow into the second casing 16 through the casing communication hole 13. The details of the filter member 90 will be described below to facilitate understanding of the structure.

The fan 60 may mainly include: a fan housing 65 that forms the exterior of the fan 60 and enables the fan 60 to be installed in the second housing 16; an impeller 63, which is provided in the fan housing 65 to allow air to flow; and a motor 61, which is provided Within the fan casing 65, the impeller 63 is provided with rotational power.

Also, a diffuser (not shown) for uniformly dispersing the airflow formed by the impeller 63 may be provided between the impeller 63 and the motor 61.

First, the motor 61 may include: a stator 611; a rotor 612, which rotates by electromagnetic reaction with the stator 611; an impeller rotation shaft 613, which connects the rotor 612 and the impeller 63 together, and has a perpendicular to the ground or the first housing cover 23 The longitudinal axis of the top surface.

The impeller rotation shaft 613 may be supported by the rotation shaft support portion 617 connected to the fan case 65, and a bearing 614 capable of rotating the impeller rotation shaft 613 may be provided between the impeller rotation shaft 613 and the rotation shaft support portion 617.

Also, the stator mounting portion 616 that fixes the stator 611 and the motor shield 618 that protects the motor 61 may be coupled to the rotating shaft support portion 617.

Therefore, if power is supplied to the motor 61, the impeller 63 can be rotated by the motor 61 so that air can flow from the front side of the second housing 16 to the rear side of the second housing 16.

Therefore, according to the above-described embodiment of the present invention, since the flow path resistance that may be generated by the complicated curved flow path of the peripheral portion of the motor 61 is reduced, the suction force or efficiency of the cleaning machine 1 can be excellently improved.

In addition, since the fan case air inflow port 651 of the fan case 65 is formed in the front plane of the fan case 65, the air that has flowed into the case communication hole 13 can pass through the second case cover 26 via the fan case 65 The exhaust hole 261 is discharged.

In this case, since the diameter of the fan housing air inlet 651 is formed to be smaller than the diameter of the fan housing on the center line in the longitudinal direction, the suction force of the fan 60 can be maximized.

In addition, a fan case supporting rib 165 protruding toward the center of the second case 16 may be provided on the inner circumferential surface of the second case 16, thereby fixing the fan case 65 to the second case 16.

The filter member 90 briefly mentioned in the foregoing description will be described in detail below. The filter member 90 may include a first filter 93 fixed to the partition 59 and a second filter 95 provided in the space between the fan case 65 and the second case cover 26.

The size of the hole formed by the mesh of the first filter 93 is configured to be larger than the size of the hole formed by the mesh of the second filter 95, so the dust can be filtered in the order of large dust to small dust.

In order to improve the quality of the exhaust air, the second filter 95 may be configured as a high efficiency particulate air (HEPA) filter. Since the HEPA filter is well known to those having ordinary knowledge in the technical field, the details will be omitted in the following description.

According to the above-described flow path structure, at least a portion of the second filter 95 is provided to face the fan housing exhaust port 653, thereby maximizing the filtering effect.

The first filter 93 may be fixed to the inner circumferential surface of the partition 59 through the first filter support rib 595 of the partition 59, and the second filter 95 may be supported by the second filter support rib 164 of the second housing 16 and The second housing cover 26 is fixed to the inside of the first housing 10.

Hereinafter, another embodiment of the flow path body will be described with reference to FIG. 6.

First, the flow path body 51 may be divided into a cylindrical first tube 513 having an open top side and a bottom side and a second tube 523 having an open top side, and a dust discharge port 51c on the bottom side.

The rising pipe 53 and the blade 55 may be provided on the first pipe 513.

The flow path body 51 can be integrated in a manner similar to the previous embodiment. In order to facilitate manufacturing through injection molding, preferably, the first tube 513 and the second tube 523 are manufactured separately.

7 and 8, the configuration relationship between the handle 70, the second housing 16 and the battery case 86 will be described in detail below.

First, referring to FIG. 7, which is a top view of the cleaning machine 1, the second housing 16 may be configured as a hollow cylindrical shape and have a diameter smaller than that of the first housing 10.

The second housing 16 may be configured to be inclined to one side so that the center line A4 in the left-right width direction is located on the left or right side with respect to the longitudinal axis A2 of the intake pipe 31. Also, the side surface of the second housing 16 in the inclined direction may be provided on the cut surface of the outer circumferential surface of the first housing 10.

In this case, the handle 70 may be configured to be inclined in a direction opposite to the inclination direction of the second housing 16.

In addition, in order to ensure a grip space for the user, at least a part of the extension portion 76 of the handle 70 may be arranged to be inclined toward the outside of the cut surface of the first housing 10 located at a position parallel to the longitudinal axis A2 of the intake pipe 31.

In this case, the longitudinal axis of the extension 76 and the longitudinal axis A2 of the intake pipe 31 form an angle equal to or less than 90°.

For ease of use, the longitudinal axis A2 of the user's arm and the intake pipe 31 need to be located side by side with each other. For this reason, the side surface of the handle body 73 may be arranged parallel to the tangent plane of the outer circumferential surface of the first housing 10 at a position where the longitudinal axis A2 of the intake pipe 31 is juxtaposed.

The battery case 86 may extend in the opposite direction of the intake pipe 31 to be side by side with the tangential direction of the first housing 10.

According to the above configuration relationship, as described above, since the center of gravity of the fan 60 is located right next to the user's grip point of the handle body 73 and the center of gravity of the battery 83 is below the user's hand, when the user moves the cleaner 1 When compared to the prior art, the torque applied to the hand is significantly reduced.
