The bottom side 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 connection portion 232 may be provided on the first housing The edge of the cover 23.

The cleaning machine 1 according to an embodiment of the present invention may further include a second housing cover 26 (refer to FIG. 9) coupled to the side of the second housing 16, which will be described in detail later.

In some embodiments, the sweeper 1 according to an embodiment of the present invention uses a cyclone effect to separate dust from the inhaled air, and the related configuration is described below.

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

A plurality of chamber housing through holes 435 may be formed in the circumferential surface of the chamber housing 43. In addition, the cavity housing perforations 435 can form a path through which the air in the first cavity 431 is filtered and flows into the second cavity 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 along the line BB′ of FIG. 3, the configuration related to the first cyclone effect occurring in the first chamber 431 will be described below.

First, the center of the air inlet 12 is set to be inclined to the right or left within a specified range with respect to the longitudinal axis of the air inlet pipe 31. Therefore, the air flowing into the first chamber 431 can follow the outer side of the chamber housing 43. The circumferential surface rotates naturally.

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

In addition, the cyclone forming member 50 may include a plurality of flow path main bodies 51, each flow path main body 51 is configured to have a cylindrical shape with an open top side and a bottom side, and its longitudinal axis is perpendicular to the first housing cover 23 or the ground, It also 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 ascending pipe 53 may be provided in each of the plurality of flow path main bodies 51, and the ascending airflow is formed in the ascending pipe 53 by the fan 60.

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

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

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

According to the above-mentioned configuration, in the cyclone forming member 50, the second cyclone effect occurs in a manner that air flows into the inflow port 51b, and then the blade 55 rotates along the dust separation flow path 51a to descend. After that, the air will rise along the riser 53.

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

The plurality of flow path main bodies 51 may be connected to each other through the connecting 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 separating member 46 having an open top side and a bottom side may be provided on the bottom side of the connecting 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 separation member 46 also has a function of preventing the air in the first chamber 431 from being sucked into the dust discharge port 51c. To this end, the top side of the dust separation part 46 is covered by the connecting plate 57, and the bottom side of the dust separation part 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, the sealing rib 233 is preferably formed of a flexible material.

In some embodiments, 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 disposed 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 riser pipe insertion holes 591 may be formed in the bottom side of the partition 59 so as to be respectively coupled with the protruding portions of the riser pipe 53.

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

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 so as to fix the partition 59 to the first housing 10.

The air rising in 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 housing 16 through the housing 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, which 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 arranged in the fan housing 65 to allow air to flow; and a motor 61, which is arranged Inside the fan housing 65, the impeller 63 is provided with rotational power.

In addition, a diffuser (not shown in the figure) for uniformly dispersing the air flow 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 through electromagnetic reaction with the stator 611; an impeller rotating shaft 613, which connects the rotor 612 and the impeller 63 together, and has a first housing cover 23 perpendicular to the ground or The length direction axis of the top surface.

The impeller rotating shaft 613 may be supported by the rotating shaft support part 617 connected to the fan housing 65, and a bearing 614 capable of rotating the impeller rotating shaft 613 may be provided between the impeller rotating shaft 613 and the rotating shaft support part 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 upper part of the second housing 16 to the lower part of the second housing 16.

The housing communication hole 13 is located above the partition 59. In this case, the air can flow into the second housing 16 without passing through a complicated tortuous flow path.

Therefore, according to the foregoing embodiment of the present invention, since the flow path resistance generated by the complicatedly curved flow path of the peripheral portion of the motor 61 is reduced, the suction force or efficiency can be excellently improved.

In addition, since the fan housing air inlet 651 of the fan housing 65 is formed in the top plane of the fan housing 65, the air that has flowed into the housing communication hole 13 can pass through the second housing cover 26 via the fan housing 65 The exhaust hole 261 is naturally exhausted.

In this case, since the diameter of the fan housing air inflow port 651 is formed to be smaller than the longitudinal center diameter of the fan housing, the suction force of the fan 60 can be maximized.

In addition, a fan housing support rib 165 protruding toward the center of the second housing 16 may be provided on the inner circumferential surface of the second housing 16 so as to fix the fan housing 65 to the second housing 16.

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

The second filter 95 can be fixed to the inside of the second housing 16 through the second filter support ribs 164 of the second housing 16 and the second housing cover 26.

Specifically, the second filter 95 may be located below the fan housing 65 and disposed to be inclined toward the second housing cover 26 with respect to the center of the left-right width direction of the second housing 16.

The second filter 95 is configured in a rectangular parallelepiped shape, and the side of the second filter 95 facing the second housing cover 26 may have a size corresponding to the size of the second housing cover 26 . Of course, the facing side can be larger than the size of the second housing cover 26.

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

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

In order to improve the quality of 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 with ordinary knowledge in the technical field, its details will be omitted in the following description.

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

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