As described above, the fan 5 is provided in the second housing 13 to move the air of the housing 1 to the exhaust unit 17, and the dust separator 4 is provided in the first housing 11 and provides The air of the air intake unit 15 is guided to the path of the fan 5. When the dust particle separator 4 moves to the fan 5 along the path, dust particles such as dust contained in the air are separated from the air by centrifugal force. The detailed structure of the dust separator 4 is as follows.

The dust separator 4 includes: a chamber forming part 41 for forming a first chamber 41a and a second chamber 41b inside the first housing 11; and a cyclone forming part 42 for forming an airflow that causes centrifugal force, and at the same time The air inside the second chamber 41b is sent to the fan 5.

The chamber forming part 41 may include: a partition 411 arranged inside the housing 1 to separate the first housing 11 and the second housing 13 from each other; the chamber bodies 413 and 415 are arranged in a cylindrical shape, and One end is fixed to the partition 411, and the other end is in contact with the first housing cover 183 to partition the internal space of the first housing 11 into two chambers 41a and 41b; The second chamber 41 b inside the main body 415 is partitioned into a first space 418 and a second space 419.

The partition 411 may even be provided in any shape that can separate the internal space of the first housing 11 from the internal space of the second housing 13. The partition 411 is provided with a partition through hole 412 passing through the partition 411.

The chamber body may be provided as a first body 413, fixed to the partition 411; and a second body 415, fixed to the first body 413. In this case, the partition through hole 412 should be provided so that the second chamber 41 b communicates with the internal space of the second housing 13. That is, the first body 413 should be provided in a shape surrounding the partition through hole 412.

The first body 413 and the second body 415 may be arranged in a hollow cylindrical shape, and the second body 415 may be arranged such that one end thereof is fixed to the free end of the first body 413, and the other end is connected to the sealing portion 189 of the first housing cover. contact.

A plurality of communication holes 414 for communicating the first chamber 41 a with the first space 418 are provided on the circumferential surface of the first body 413. Therefore, the air entering the first chamber 41 a through the air intake unit 15 may be supplied to the first space 418 of the second chamber 41 b through the communication hole 414.

The discharge hole 416 (see FIG. 3) is provided on a surface of the second body 415, and the surface is in contact with the sealing portion 189 of the first housing cover. When the first cover body opens the lower through hole 181, the dust particles stored in the second body 415 may be discharged to the outside of the housing through the discharge hole 416.

The body partition 417 is fixed to any one of the first body 413 and the second body 415 to partition the inside of the second chamber 41 b into two spaces 418 and 419. The first space 418 is a space communicating with the partition through hole 412, and the second space 419 is a space not communicating with the partition through hole 412.

As shown in FIG. 3, the cyclone forming part 42 may include: a path main body 421, one end of which is fixed to the partition 411, and the other end communicates with the second space 419 by passing through the main partition 417; and a discharge pipe 424 located in the path main body 421 is inside and communicates with the partition through hole 412; the inlet 423 is provided to pass through the circumferential surface of the path main body 421; and the air flow forming part 425 is provided between the outer circumferential surface of the discharge pipe 424 and the inner circumferential surface of the path main body 421.

The path main body 421 is provided as a pipe surrounding the partition through hole 412, and the discharge pipe 424 is located inside the path main body 421. The path main body 421 communicates with the second space 419 through a dust discharge hole 422 provided on the free end (the bottom surface of the path main body). The path body 421 may be provided to have a diameter that becomes smaller toward the free end. This is to strongly maintain the strength of the air flow formed in the path main body 421.

The airflow forming part 425 is provided in a spiral shape, and the inlet 423 is located higher than the airflow forming part 425. Therefore, when the fan 5 is operated, the air entering the path main body 421 through the inlet 423 will move through the airflow forming part 425 to the discharge pipe 424 to rotate in the middle of the inside of the path main body 421 (cyclonic motion).

If cyclonic motion occurs inside the path main body 421, the dust particles contained in the air move to the edge of the path (the circumferential surface of the path main body) by centrifugal force, and then are discharged into the second space 419 by gravity.

Unlike the diagram shown, the inlet 423 may be provided as a hole provided to pass through the upper surface of the path main body 421. In this case, the upper end of the path main body 421 should be set to be spaced apart from the partition 411 and not fixed to the partition 411. Since the path main body 421 is fixed to the partition 411 by the airflow forming part 425 and the discharge pipe 424, even if the upper end of the path main body 421 is spaced apart from the partition 411, the path main body 421 can maintain a state of being fixed to the partition 411.

The cyclone forming portion 42 having the above-mentioned structure may be provided with a plurality of cyclone forming portions. FIG. 3 shows an example of the dust particle separator 4 provided with nine cyclone forming parts 42.

As shown in FIG. 2, the fan 5 may include: a housing 51 provided in the second housing 13; an impeller 57 rotatably provided inside the housing; and a motor 54 fixed to the housing to rotate the impeller 57 .

This is to minimize the path resistance between the partition through hole 412 and the exhaust hole 175.

The motor 54 is fixed to a support 515 provided in the housing 51. FIG. 2 shows an example of a case where the support 515 is located between the housing air inlet 511 and the housing air outlet 513, and the rotating shaft 545 is connected to the impeller 57 by passing through the support 515. That is, the motor 54 may include: a fixing unit 541 fixed to the support 515; a stator 543 arranged inside the fixing unit 541; and a permanent magnet 546 fixed on the free end of the rotating shaft 545 (the rotating shaft located inside the fixing unit) one).

The motor 54 may be set to be powered by a power source provided in the room, or may be set to be powered by a battery 7 detachably provided in the housing 1.

Meanwhile, in order to filter the dust particles not removed by the dust particle separator 4, the present invention may further include at least one of the first filter 91 and the second filter 92. FIG. 2 shows an example of a case where the first filter 91 and the second filter 92 are provided in the cleaning machine 100 of the present invention.

The first filter 91 may be located between the second communication hole 19 and the housing air inlet 511 and configured to filter air, and the second filter 92 may be located between the housing air vent 513 and the air outlet 175, And set to filter the air.

The first filter 91 and the second filter 92 may be provided to filter dust particles of the same size, or may be provided to filter dust particles of different sizes. In the latter case, it is preferable that the second filter 92 filters dust particles smaller than the dust particles filtered by the first filter 91. This is to reduce the amount of dust discharged into the indoor space.

Hereinafter, the operation process of the sweeping machine having the above-mentioned structure will be described with reference to FIG. 4.

If power is supplied to the motor 54 to rotate the impeller 57, air enters the first chamber 41a through the intake pipe 151 and the intake hole 153. A guide 155 is provided in the air intake pipe 151 for allowing air discharged from the air intake hole 153 to enter the first chamber 41 a in the tangential direction of the circumferential surface of the first chamber 41 a. Therefore, the air entering the first chamber 41a will move in a cyclonic manner along the circumferential surface of the first chamber 41a.

If the air cyclone moves inside the first chamber 41a, the dust particles will move to the circumferential surface of the first chamber 41a through centrifugal force, and then move to the first housing cover provided on the bottom surface of the first housing 11 through gravity 183, and air will enter the second chamber 41b through the communication hole 414.

The air entering the second chamber 41b moves to the path main body 421 through the inlet 423, and the air entering the path main body 421 will move in a cyclone manner while passing through the airflow forming portion 425.

If cyclone motion occurs in the path main body 421, the dust particles contained in the air move to the circumferential surface of the path main body 421 through centrifugal force, and then are discharged to the second space 419 by gravity, and the air will pass through the discharge pipe 424 and separate the through holes. 412, the housing air inlet 511, the housing air outlet 513, and the air outlet 175 are discharged to the outside of the housing 1.

The user can open the lower through hole 181 by rotating the first chamber 41a to remove the dust particles collected in the second space 419 and the first chamber 41a.

As shown in FIGS. 2 and 5, it is preferable that the straight line V2 passing through the center of gravity G2 of the fan 5 is set based on the straight line V1 passing through the center of gravity G1 of the dust separator, at an angle ranging from 0° to 90° tilt. That is, it is preferable that the rotation shaft 545 is set to be inclined at an angle A between 0° and 90° toward the direction in which the handle 8 is based on a straight line V1 passing through the center of gravity G1 of the dust particle separator.

If the rotating shaft 545 is set in a direction perpendicular to the straight line V1 passing through the center of gravity G1 of the dust separator, the air can be discharged toward the direction where the handle 8 is located, which may cause discomfort to the user and spray fine dust to the user. The problem with the person.

At the same time, if the dust separator 4 and the fan 5 are located in the upper and lower positions, so the rotating shaft 545 is located on the straight line V1 passing through the center of gravity of the dust separator, it may happen that the center of gravity G1 of the dust separator and the center of gravity G2 of the fan are both located Problem with the front end of the handle 8. The situation that the center of gravity of the sweeper is far away from the handle 8 means that the center of gravity of the sweeper is located far away from the user’s wrist, and if the center of gravity of the sweeper is far away from the user’s wrist, it will take a lot to change the direction or position of the sweeper. The question of strength.

The angle A set in the rotating shaft 545 can solve the above two problems. That is, since the angle of the rotating shaft 545 is less than 90°, the air will not be discharged to the direction where the handle 8 is located.

Moreover, since the center of gravity G2 of the fan is close to the handle 8, if the angle A of the rotation shaft 545 with respect to the straight line V1 passing through the center of gravity of the dust separator is 0°, the center of gravity of the sweeper can move to the direction where the handle 8 is located. Therefore, the user can operate the cleaning machine 100 by using a relatively small force.

At the same time, it is preferable that the angle of the second housing 13 inclined toward the handle 8 with respect to the vertical line passing through the center of the first housing 11 is set equal to the straight line V1 (vertical The straight line to the first cover) the angle A of the inclined rotation axis 545.

However, it is preferable that the inclination angle A of the rotating shaft 545 with respect to the straight line V1 passing through the center of gravity of the dust particle separator is set to an angle of 30° to 60°. This is because if the inclination angle A is less than 30°, it is difficult to predict a big difference from the conventional sweeper with an inclination angle of 0°, and if the inclination angle A is greater than 60°, it is also difficult to predict the difference from the inclination angle of 90°. Traditional sweepers are very different.

FIG. 5 is an example showing a case where the inclination angle A of the rotating shaft 545 with respect to the straight line V1 passing through the center of gravity of the dust particle separator is set to 45°. According to experiments, in this case, it is estimated that the load that the user feels when handling the cleaning machine is the lowest.

As described above, the motor 54 provided in the fan may be provided to be powered by the battery 7 detachably provided in the housing 1. In this case, the circumferential surface of the first case 11 should be provided with a battery case 6 for storing the battery 7.

The battery case 6 provided in the present invention is located in the space provided by the circumferential surface of the first case 11 at a point (points spaced 180° apart) opposite to the point where the air intake unit 15 is located. Also, the battery case 6 is provided to protrude in a direction away from the circumferential surface of the first case 11.

The battery 7 can be detachably inserted into the battery case 6 through an insertion hole 61 (see FIG. 1) provided to pass through the bottom surface of the battery case 6 and a side surface of the battery case 6.

In this case, one end of the handle 8 may be fixed to the circumferential surface of the second housing 13, and the other end of the handle 8 may be fixed to the upper surface of the battery housing 6. That is, the handle 8 may include: a rod-shaped handle body 81 extending from the battery case 6 toward the second case 13; and a rod-shaped connecting body 83 that connects the handle body 81 to the circumferential surface of the second case 13.

The handle body 81 may be provided to have an inclination angle of 70° to 80° with respect to a reference line L1 passing through the center of the air intake unit. FIG. 5 shows an example of a case where the straight line L2 passing through the center of the handle body 81 has an inclination angle of 75° with respect to the reference line L1.

If the height of the battery case 6 is increased, the length of the handle body 81 may be reduced, which may cause inconvenience to the user. Therefore, the length of the battery 7 from the circumferential surface of the first case 11 to the direction in which the handle body 81 is located ( The length of the battery in the Y-axis direction) is set to be longer than the length of the battery 7 in the height direction relative to the first casing 11 (the length of the battery in the Z-axis direction) and the length of the battery 7 in the radial direction relative to the first casing 11 (X-axis Direction the length of the battery).

In addition, preferably, the center of gravity G2 of the fan is located between the center of gravity G1 of the dust separator and the center of gravity G3 of the battery, and the center of gravity G3 of the battery can be set to be located between the center of gravity G2 of the fan and the center of gravity G4 of the handle 8. This is to allow the user to operate the sweeper by using a small force by arranging each of the centers of gravity G1, G2, and G3 close to the center of gravity G4 of the handle.

At the same time, even if the center of gravity G2 of the fan is between the center of gravity G1 of the dust separator and the center of gravity G3 of the battery, and the center of gravity G3 of the battery is between the center of gravity G2 of the fan and the center of gravity G4 of the handle, if the fan, the dust separator and the battery The center of gravity of G1, G2, and G3 are on a straight line, and the center of gravity of the sweeper will be far away from the handle 8.

Therefore, it is preferable that the center of gravity G2 of the fan is located above the reference line L1 passing through the center of the intake unit 15, and the center of gravity G1 of the dust separator and the center of gravity G3 of the battery are located on the reference line L1 passing through the center of the intake unit. Below.

However, the center of gravity G4 of the handle may be located on the reference line L1 passing through the center of the air intake unit, or may be located below the reference line L1 passing through the center of the air intake unit.

In addition, as shown in FIG. 6, it is preferable that the center of gravity G2 of the fan, the center of gravity G1 of the dust separator, the center of gravity G3 of the battery, and the center of gravity G4 of the handle are all set on a single plane (the height direction portion of the cleaner). That is, preferably, the center of gravity G2 of the fan, the center of gravity G1 of the dust separator, the center of gravity G3 of the battery, and the center of gravity G4 of the handle are all located on a single vertical line including a straight line passing through the center of the air intake unit. This is because the case where the centers of gravity G1, G2, G3, and G4 are all located in the height direction portion (Z-axis direction) of the cleaning machine is more conducive to the operation of the cleaning machine.
