Description

Technical Field The present invention relates to a vacuum cleaner using an axleless motor having a helical screw rotor structure,

[0001] The present invention relates to a vacuum cleaner, and in particular, a motor having a spiral screw rotor structure for generating air sucked into a vacuum cleaner is installed between a head of a vacuum cleaner and a dust collector of a vacuum cleaner, The present invention relates to a vacuum cleaner using an axleless motor of a helical screw rotor type which is provided with a plurality of filters and a dust outlet of a silencer structure in a discharge path so that clean noise is small and clean air can be discharged.

Fig. 1 shows an embodiment in which a conventional vacuum cleaner collects dust.

FIG. 1A is an overall view of a conventional vacuum cleaner, and FIG. 1B is an internal sectional view of the cleaner main body.

1, a conventional vacuum cleaner includes a main body 40 including a vacuum cleaner head 10, a connection pipe 20, an extension pipe and a connection pipe, a hose 30, a dust collecting device, and a suction motor. . In view of the flow of air in the vacuum cleaner, the conventional vacuum cleaner reaches the main body 40 via the cleaner head 10, the connecting pipe 20 and the hose 30, And the dust is filtered by the filter constituting the dust collector 41. In the conventional vacuum cleaner, a fan 43, which is operated by a motor 42, is mounted behind the dust collector 41. As the fan 43 connected to the motor 42 rotates, air is blown to the outside of the vacuum cleaner The pressure around the fan 43 is lowered and the air flows in the reverse direction from the head portion 10 to the main body 40 via the connecting pipe 20 and the hose 30, .

If the cleaning is performed using a vacuum cleaner, dust or the like will be filled in the dust collector 41. Referring to FIG. 1B, the dust filled in the dust collector 41 may cause the suction force of the vacuum cleaner to be reduced. This is because the dust that is filled in the dust collector 41 is located in the forward direction of the intake air of the motor 42 during the cleaning. When the dust collector 41 is filled with a certain amount of dust and the suction power is decreased, The cleaner is designed to increase the rotational speed of the motor 42 so as to maintain a constant suction force.

The increase in the rotational speed of the motor 42 increases the power consumption of the vacuum cleaner, thereby causing a considerable noise from the vacuum cleaner.

4 is an embodiment of an axleless motor constituting the vacuum cleaner of the present invention.

4A is a perspective view of the axleless motor, FIG. 4B is an exploded perspective view of the axleless motor shown in FIG. 4A, FIG. 4C is a side sectional view of the axleless motor, and FIG. 4D is a front sectional view of the axleless motor.

4, the axleless motor 221 is composed of a stator 410 and rotors 420 (421, 422, 423).

The stator 410 is inserted and fixed in a cylindrical shape between the head part 210 and the connecting pipe 222 and has a plurality of rotational energy winding modules 411 and a rotor magnetic levitation winding module 412 Respectively. The winding module for rotational energy 411 functions to induce the rotation of the rotor 420 and the winding module for magnetic levitation 412 rotates the inside of the stator 410 when the rotor 420 rotates. And functions to prevent a frictional force due to collision with the left and right sides from occurring.

The rotor 420 is installed in the hollow interior of the stator 410 and includes a helical screw rotor 421 of a diameter corresponding to the inner diameter of the coupling tube 222, And a plurality of rotor permanent magnets 423 inserted and fixed in the auxiliary portion 422 and the rotation auxiliary portion 422. Although FIG. 4 shows six winding modules and six rotor permanent magnets, the number of rotor permanent magnets can be selected by a multiple of two and can be selected corresponding to the number of water rotor permanent magnets in the winding module.

In the present invention, air including dust will flow through the rotating blades of the helical screw rotor 421 constituting the rotor 420. When the vacuum cleaner is used, But also an object having a certain volume such as paper or paper can be introduced. Therefore, the material, the thickness, and the shape of the rotating blade of the helical screw rotor 421 may be produced in consideration of this situation. In addition, a through hole 421a is formed at the center of the helical screw rotor 421. The through hole 421a is formed in a hollow shape passing through the center from one side of the helical screw rotor 421 to the other side and flows into the inside of the axleless motor 221 by passing an object having a larger volume than dust The flow of air can be prevented from being blocked.

Since the rotor 420 rotates without contacting the stator 410 in the state where the axle is not axleed, a constant gap is formed between the rotor 420 and the stator 410, The rotor permanent magnet 423 is inserted into the gap between the rotor 420 and the stator 410 to minimize the amount of dust that is sucked through the helical screw rotor 421 and inserted into the gap between the rotor 420 and the stator 410. [ It is proposed that the shape of the rotation auxiliary portion 422 fixed and the constant surface of the stator 410 have the following shape.

The rotation auxiliary portion 422 into which the rotor permanent magnet 423 is inserted has a predetermined inclination from a portion contacting the helical screw rotor 421 in a direction away from the helical screw rotor 421. [ The inner surface of the stator 410 corresponding to the inclined shape of the rotation auxiliary portion 422 also has the same inclined surface as the inclination of the rotation assist portion 422.

Here, the inclination is formed so as to form an acute angle (?) With the surface of the air generated by the axleless motor 221. In Fig. 4B, although the acute angle [theta] is shown only on the left side of the axleless motor 221, it can be seen that the end of the right portion also forms an acute angle [theta].

Particularly, the right part of FIG. 4B is a state in which the stator 410 of the axleless motor 221 can be separated (410-1) from each other so that the rotor 420 constituting the axleless motor 221 can be replaced, Separate embodiments to facilitate cleaning are also possible, as well as integral embodiments. In the case of the separable type, the fastening grooves 411 and the fastening holes 410-2 are formed in the respective stator 410 and 410-1 so that the separated stator 410 and 410-1 are fastened by the fastening means 450 .

5 is a perspective view of a vacuum cleaner according to an embodiment of the present invention.

FIG. 5A is an exploded view of the vacuum cleaner according to the present invention, FIG. 5B is a combined view of the vacuum cleaner according to the present invention, and FIG. 5C shows a structure of a silencer.

5, the dust collector 230 includes a dust collector 510, a housing 520, a primary filter 530, an air guide cone 540, a silencer 550, a secondary filter 560, A filter 570 and a lid 580.

The dust collector 510 is fastened to the lower portion of the housing 520 using a screw thread 511 formed on the outer surface. 5A shows two types of dust collectors, one for a portable vacuum cleaner on the left, and the other for the mobile vacuum cleaner with a wheel 512 added to the dust collector on the right.

The housing 520 has an air inlet hole 521 connected to the hose 224 on the outer surface thereof and a multifunctional air descending wall 522 formed on the inner surface thereof. The multifunctional air drop wall 522 is formed in the middle of the housing 520 so that the second filter 560 can be seated by forming a step 523 in the middle of the housing 520, A wall is formed in the lower direction so that the dust air applied to the air inlet hole 521 is transmitted to the lower portion of the air guide cone 540 to be described later so as to guide the direction in which the dust air flows in the housing 520.

The primary filter 530 is installed at a lower portion of the multifunctional air drop wall 522 to filter dust of a predetermined size or more among the air introduced into the lower portion of the housing 520. The primary filter 530 may be implemented as a net having a mesh structure of a predetermined size. The air guide cone 540, which is formed by inverting the con (con), is installed under the multifunctional air drop wall 522 and guides the traveling direction of the air passing through the primary filter 530.

The secondary filter 560 seats on the multifunctional air drop wall 522 to filter dust contained in the air moving along the air guide cone 540. As an example of the secondary filter 560, there is a sponge. The air guide cone 540 and the multifunctional air intensifying wall 522 should be spaced apart from each other such that air can be introduced into the secondary filter 560 from the air guide cone 540.

The silencer 550 weakens the noise generated by the air passing through the secondary filter 560 in the housing 520. The structure of the silencer 550 will be described later. The tertiary filter 570 filters the dust contained in the air passing through the silencer 550, and suggests using the HEPA filter in the present invention.

Here, the HEPA filter (HEPA filter) is an air purification device developed for purifying radioactive particles in the air, and is widely used for air conditioning of a clean room.

Referring to FIG. 5B, the dust air introduced from the hose 224 moves along the arrow in the dust collecting apparatus 230, and finally, is discharged into the air discharge hole 581 of the lid 580. It can be seen that the dust air passes through the primary filter 530, the secondary filter 550, the silencer 560 and the third filter 570 in turn. Particularly, it can be seen that the dust collector 510 is out of the traveling path of the dust air, which is different from the conventional vacuum cleaner in that the dust collector 510 is positioned on the path of the dust air to lower the suction force of the vacuum cleaner .

5C, silencers 560 (561 to 563) are provided with noise units 561, 562 and 563 having different diameters in the form of concentric circles. In the upper part of the silencer 560, the upper part of the noise units 561 and 562 excluding the upper part of the noise unit 563 having the smallest diameter, that is, the upper part of the noise units 561 and 562, The noise generated during the process of gathering the air passing through the second filter 560 installed on the outer surface of the outermost noise unit 561 to the center of the muffler 560 is minimized. For this purpose, a plurality of holes A, B and C are respectively formed in the noise units 561, 562 and 563. For example, a plurality of holes A formed in one noise unit 562, The plurality of holes (B) formed in the succeeding noise unit (563) are formed so as not to be located on the same line on which the air advances.

Therefore, in the vacuum cleaner using the axleless motor of the helical screw rotor structure according to the present invention, the axleless motor 222 of the helical screw rotor structure for generating the air sucked into the inside is connected to the head part 210 and the dust collecting device 230, and a plurality of filters and a muffler-structured dust outlet are provided in the air discharge path of the dust collecting device 230 to reduce clean noise, to discharge clean air, and to prevent the first suction force from being reduced have. Here, the axleless motor 221, which is one of the key components of the present invention, is a concept originally used in the present invention. In general, the motor is rotated about the rotational axis of the rotor, 420 are designed to be capable of fluid movement in the axleless motor 221 itself by coupling a helical screw rotor to the space in which the rotation axis of the axleless motor 221 is to be positioned.
