[0020] 1 to 5, a vacuum cleaner 1 according to an embodiment of the present invention includes a main body 2. can be done.

[0021] The vacuum cleaner 1 may further include a suction unit 5 coupled to the front of the main body 2. The suction part 5 can guide the air containing dust to the main body 2 .

[0022] The vacuum cleaner 1 may further include a handle 3 coupled to the main body 2. The handle portion 3 may be located on the opposite side of the main body 2 from the intake portion 5 .

[0023] That is, the main body 2 can be disposed between the inhalation portion 5 and the handle portion 3 .

[0024] The main body 2 comprises a first body 10 and a second body 11 positioned above the first body 10. It can include 12.

[0025] The first body 10 and the second body 12 are formed in a cylindrical shape, but are not limited thereto. obtain.

[0026] The center of the intake portion 5 is roughly the same as the first body 10 and the second body 11. The intake portion 5 can be coupled to the main body 2 so as to be located at the boundary between the intake portion 5 and the main body 2 .

[0027] The main body 2 includes a dust separating unit for separating dust from the air drawn in through the suction unit 5. It can further include:

[0028] The dust separation unit may be, for example, a second unit capable of separating dust by cyclone flow. The first body 10 may include a first cyclone unit 110. It includes a cyclone section 110 .

[0029] The air and dust sucked through the suction unit 5 are guided to the inner circumferential surface of the first cyclone unit 110. The fluid will flow in a spiral along the line.

[0030] The axis of the cyclone flow of the first cyclone unit 110 may extend in the vertical direction.

[0031] The dust separation unit separates dust again from the air discharged from the first cyclone unit 110. In this case, the dust separating unit may further include a second cyclone unit 130. The second cyclone section 130 is positioned within the first cyclone section 18 so as to minimize size. The second cyclone unit 130 may be located inside the cyclone unit 130. The antibody may include a steroid molecule.

[0032] As another example, the dust separating unit may have a single cyclone unit. In any case, the axis of the cyclone flow may extend in the vertical direction.

[0033] The first body 10 stores the dust separated from the cyclone units 110 and 130. The main body 2 has a button for opening and closing the bottom of the first body 10. The body cover 16 may further include a body cover 16. The body cover 16 is rotated. The first body 10 can be opened and closed by the opening and closing.

[0034] At least a portion of the second cyclone unit 130 may be located within the first body 10. do.

[0035] The first body 10 stores dust separated from the second cyclone unit 130. A dust storage guide 124 may be arranged to guide the dust storage guide 124. 2. The cyclone unit 130 is connected to the lower side of the cyclone unit 130 and contacts the upper surface of the body cover 16. can be done.

[0036] The dust storage guide 124 separates the internal space of the first body 10 from the first cycle. a first dust storage section 121 in which dust separated from the second cycle section 110 is stored; The second dust storage section 123 stores the dust separated from the first dust storage section 130. can.

[0037] The internal space of the dust storage guide 124 is the second dust storage portion 123, The space between the storage guide 124 and the first body 10 is a first dust storage portion 121 .

[0038] At least a part of the dust storage guide 124 has a diameter that decreases from the top to the bottom. For example, a portion of the upper portion of the dust storage guide 124 may be formed as follows: It may be formed to have a reduced diameter.

[0039] The dust storage guide 124 extends downward from the upper end of the dust storage guide 124. The anti-scattering rib 124a may include, for example, The dust storage guide 124 is formed cylindrically and can surround the upper side of the dust storage guide 124.

[0040] At this time, the diameter of the dust storage guide 124 decreases from the upper part to the lower part. Therefore, there is a gap between the outer peripheral surface of the upper part of the dust storage guide 124 and the scattering prevention rib 124a. A space is formed.

[0041] The cyclone flow flows along the inner circumferential surface of the second body 10 and descends. In the process of the cyclone flow descending, the cyclone flow When the first dust particles come into contact with the first dust particles 16, the rotational flow may change to an upward flow. When an upward flow exists in the storage unit 121, the dust stored in the first dust storage unit 121 There is a problem that the particles scatter and flow back into the second cyclone section 130.

[0042] In the present invention, the upward flow in the first dust storage portion 121 is prevented by the scattering prevention rib 124a. and the upper part of the dust storage guide 124 by the scattering prevention rib 124a. The downward flow is changed again, so that the dust stored in the first dust storage part 121 is prevented from scattering. This prevents the dust from flowing back to the second cyclone unit 130. .

[0043] On the other hand, the scattering prevention rib 124a extends downward from the upper end of the dust storage guide 124. Therefore, the dust separated from the first cyclone unit 110 along with the cyclone flow is The scattering prevention rib 124a allows the dust particles to move smoothly into the first dust storage portion 121. can.

[0044] The body cover 16 includes the first dust storage portion 121 and the second dust storage portion 123. Both can be opened and closed.

[0045] The vacuum cleaner 1 includes a suction motor 20 for generating suction power, and a power supply for the suction motor 20. and a battery 40 for providing a power source.

[0046] The suction motor 20 may be located within the second body 12. At least a part of the motor 20 may be located above the dust separating unit. The motor 20 may be located above the first body 10 .

[0047] The suction motor 20 may be connected to the outlet of the second cyclone unit 130. .

[0048] For this purpose, the main body 2 has a discharge guide 28 connected to the second cyclone unit 130. and a flow guide 22 that is in communication with the discharge guide 28.

[0049] For example, the discharge guide 28 is located above the second cyclone unit 130, The flow guide 22 may be located above the discharge guide 28 .

[0050] At least a part of the suction motor 20 is located inside the flow guide 22. obtain.

[0051] Therefore, the axis of the cyclone flow of the first cyclone unit 180 is the same as that of the suction motor 2. It can penetrate 0.

[0052] When the suction motor 20 is positioned above the second cyclone unit 130, The air discharged from the crown 130 can immediately flow to the suction motor 20 side. Therefore, the flow path between the dust separator and the suction motor 20 can be minimized.

[0053] The suction motor 20 includes a rotating impeller 200. The roller 200 may be connected to a shaft 202. The shaft 202 may extend in the vertical direction. will be placed in.

[0054] The impeller 200 is positioned at the upper side of the suction motor 20. In this case, the impeller 200 can be used to draw air into the intake motor. The fluid can flow from the top to the bottom of the rotor 20.

[0055] The extension line of the shaft 202 (which can also be called the rotation axis of the impeller 200) is At this time, the rotation shaft of the impeller 200 and the dust particles can pass through the dust particles. The axis of the cyclone flow generated from the first cyclone section 110 at the remote location can be positioned on the same line. do.

[0056] According to the present invention, the air discharged from the dust separation unit, i.e., the second cyclone unit 1 The air discharged upward from the intake motor 30 has fewer paths to flow to the intake motor 20. This has the advantage of reducing the change in direction, thereby reducing air flow loss.

[0057] When the air flow loss is reduced, the suction force increases, and the suction motor 20 is supplied with power. This increases the battery life.

[0058] The vacuum cleaner 1 includes an upper motor housing 20 that covers a portion of the upper side of the suction motor 20. 26 and a lower motor housing 27 that covers a part of the lower side of the suction motor 20. It can also include:

[0059] The suction motor 20 is housed inside each of the motor housings 26, and the flow guide The motor 22 may be positioned to surround the upper motor housing 26 .

[0060] At least a portion of the flow guide 22 is spaced apart from the upper motor housing 26. In addition, at least a part of the flow guide 22 is separated from the second body 12. It can be separated.

[0061] Therefore, the inner peripheral surface of the flow guide 22 and the outer peripheral surface of the upper motor housing 26 , forming a first air flow path 232, and the outer circumferential surface of the flow guide 22 and the second body 12 The inner circumferential surface forms a second air flow path 234 .

[0062] According to the present invention, a single flow guide 22 has a first air flow path 232 and a second air flow path 234. This simplifies the structure by reducing the number of parts required to form each air flow path. There is an advantage to being able to do this.

[0063] The first air passage 232 serves as an intake passage, and the second air passage 234 serves as an exhaust passage. It plays a role in

[0064] The air discharged from the second cyclone unit 130 flows along the first air flow path 232. The air flowing into the suction motor 20 and discharged from the suction motor 20 is the second air The air flows along the flow path 234 and is then discharged to the outside. 4 serves as an exhaust passage.

[0065] The handle portion 3 includes a handle 30 for a user to hold, and a lower part of the handle 30. and a battery housing 410 disposed in the

[0066] The handle 30 may be located rearward of the suction motor 20 .

[0067] The direction is defined as the forward direction in the vacuum cleaner 1 with the suction motor 20 as the reference. The direction in which the suction unit 5 is located is the front, and the direction in which the handle 30 is located is the rear. .

[0068] The battery 40 may be located behind the first body 10. The suction motor 20 and the battery 40 are arranged so as not to overlap each other in the vertical direction. Alternatively, they may be arranged differently.

[0069] According to the present invention, the weight of the suction motor 2 is heavy based on the handle 30. 0 is located in front of the handle 30, and the heavy battery 40 is located in front of the handle 30. Since it is located at the bottom, the weight of the vacuum cleaner 1 is evenly distributed throughout the vacuum cleaner. When holding the handle 30 for cleaning, strain on the user's wrist can be prevented. That is, the heavy components are distributed in the front and rear of the vacuum cleaner 1, and the weights are different from each other. Since it is disposed at a height, the center of gravity of the vacuum cleaner 1 can be prevented from tilting to one side.

[0070] The battery 40 is located below the handle 30, and the suction motor 20 is located below the handle 30. Since the handle 30 is located in front of the handle 30, there is no structure above the handle 30. That is, the upper surface of the handle 30 forms part of the appearance of the upper surface of the vacuum cleaner 1.

[0071] Therefore, in the process of using the vacuum cleaner 1 by grasping the handle 30, a certain configuration of the vacuum cleaner 1 is Contact with the arm can be prevented.

[0072] The handle 30 has a first extension 310 that extends vertically and can be grasped by a user. and a second extension portion 310 extending from the upper side of the first extension portion 310 toward the suction motor 20. 20. At least a portion of the second extension 320 may extend horizontally. do.

[0073] The first extension 310 is configured such that the user's hand is in contact with the first extension 310 when the user grasps the first extension 310. 1. A movement control for preventing the extension part 310 from moving in the length direction (up and down direction in FIG. 2). The movement limiting portion 312 may be provided between the first extension portion 310 and the second extension portion 310. It may extend towards the intake portion 5.

[0074] The movement limiting portion 312 is spaced apart from the second extending portion 320. When the first extension portion 310 is gripped, some of the fingers are positioned above the movement limiting portion 312. The remaining fingers may be positioned below the movement limiter 312.

[0075] As an example, the movement limiter 312 may be located between the index finger and the middle finger.

[0076] With this arrangement, the user can hold the first extension 310 and then press the inlet port. The longitudinal axis A1 of the 5 can pass through the user's wrist.

[0077] When the longitudinal axis A1 of the inhaler 5 passes through the user's wrist, The longitudinal axis A1 of the inhalation portion 5 may be substantially aligned with the extension of the user's arm. Therefore, in this state, the user cannot grasp the handle 30 and operate the vacuum cleaner 1. This has the advantage that the force required by the user when pushing or pulling is minimized.

[0078] The handle 30 may include an operating portion 326. 6 may be located on an inclined surface formed on the second extension portion 320. On and off commands for the vacuum cleaner suction motor can be input.

[0079] The operating portion 326 may be positioned so as to face the user. The operating portion 326 may be located on the opposite side of the movement limiting portion 312 .

[0080] The operating portion 326 may be positioned higher than the movement limiting portion 312. The user can easily operate the operating portion 326 with the thumb while grasping the first extension portion 310. It is possible.

[0081] In addition, since the operating portion 326 is located at a position separated from the first extension portion 310, When cleaning is performed while holding the first extension portion 310, the operating portion 326 may be unintentionally operated. This can prevent the data from being lost.

[0082] The second extension 320 may include a display 322 for displaying an operating state. For example, the display unit 322 may be located on the upper surface of the second extension unit 320. Therefore, when the user is cleaning, the display unit 322 located on the upper surface of the second extension part 320 is The display unit 322 can easily display, for example, the remaining charge of the battery 40, The strength of the suction motor, etc. can be displayed.

[0083] The display unit 322 may include, but is not limited to, a plurality of light emitting units. The light emitting portions may be arranged at intervals in the length direction of the second extension portion 320 .

[0084] The battery housing 410 may be located below the first extension 310 .

[0085] The battery 40 may be releasably coupled to the battery housing 410 . As an example, the battery 40 is inserted from below the battery housing 410. The battery housing 410 may be inserted inside the battery housing 410.

[0086] The rear surface of the battery housing 410 and the rear surface of the first extension 310 are continuous. Therefore, the battery housing 410 and the first extension The long portion 310 can have a sense of unity.

[0087] The battery 40 is housed in the battery housing 410. Therefore, when the vacuum cleaner 1 is placed on the floor, The battery 40 can then be placed on the floor.

[0088] According to this structure, the battery 40 can be easily removed from the battery housing 410. This has the advantage of allowing for immediate separation.

[0089] In addition, since the bottom surface of the battery 40 is exposed to the outside, The battery 40 can be in direct contact with the air outside the vacuum cleaner 1, and the cooling performance of the battery 40 can be improved.

[0090] Meanwhile, referring to FIG. 3, the vacuum cleaner 1 has a suction motor 20, through which air is discharged. The air outlet 522 may further include a filter mechanism 50. The outlet 522 may include, for example, a plurality of openings, which may be arranged in a circumferential direction. Thus, the air outlets 522 may be arranged in a ring shape.

[0091] The filter mechanism 50 can be removably coupled to the upper side of the main body 2. The rotor mechanism 50 can be detachably housed in the second body 12 .

[0092] When the filter mechanism 50 is coupled to the main body 2, a part of the filter mechanism 2 can be located outside the second body 12. Therefore, one of the filter mechanisms 50 The part is drawn into the inside of the main body 2 through the upper opening of the main body 2, and the other part is drawn into the inside of the main body 2. protrudes outside.

[0093] The height of the main body 2 may be substantially the same as the height of the handle 30. The filter mechanism 50 protrudes upward from the main body 2, and the user can The filter mechanism 50 can be easily separated while the mechanism 50 is held.

[0094] The filter mechanism 50 is attached to the main body 2. The air outlet 522 may be located on the side of the suction motor 20. The air is discharged above the main body 2 .

[0095] According to this embodiment, during the cleaning process using the vacuum cleaner 1, air is exhausted from the air outlet 522. The released air may be prevented from flowing towards the user.

[0096] The main body 2 has a pre-filter for filtering the air flowing into the suction motor 20. The flow guide 22 may further include a pre-filter 29. The pre-filter 29 may be located within the upper motor housing 26. The upper motor housing 26 may be attached to the upper The motor housing 26 has a filter support portion for supporting the pre-filter 29. It can include.

[0097] When the filter mechanism 50 is attached to the main body 2, the filter mechanism 50 is Pressurizing the pre-filter 29 to prevent movement of the pre-filter 29 can be done.

[0098] In one example, the filter mechanism 50 may pressurize the pre-filter 29 downward. Therefore, according to the present invention, the structure for fixing the pre-filter 29 is The advantage is that it does not require

[0099] FIG. 6 is a view showing a state in which the filter mechanism according to an embodiment of the present invention is separated from the main body. 7 is a view of the underside of a filter mechanism according to one embodiment of the present invention, and FIG. FIG. 9 is an exploded perspective view of the filter mechanism of FIG. 7; FIG. is.

[0100] 5 to 9, the filter mechanism 50 can be separated from the main body 2. do.

[0101] As an example, the filter mechanism 50 may be separated above the main body 2 .

[0102] The impeller 200 is disposed above the suction motor 20, The pre-filter 29 is attached to the upper motor housing so as to cover the impeller 200. 26.

[0103] Therefore, when the filter mechanism 50 is separated from the main body 2, the prefix The pre-filter 29 can be exposed to the outside, so that the pre-filter 29 can be separated. It becomes possible.

[0104] The pre-filter 29 may include a tab 29a. The knob 29a of the pre-filter 29 is grasped and the pre-filter 29 is lifted upward. The pre-filter 29 can be separated from the main body 2 by lifting it up. The pre-filter 29 can be separated from the main body 2, so that the user can easily remove the pre-filter 29. can be cleaned.

[0164] The inner circumferential surface of the inner body 571 is provided with a rib for coupling with the flow guide 22. A coupling portion 577 may be provided.

[0165] The inner body 571 is extended so that the rib connecting portion 577 extends downwardly. The extension 576 may include an extension portion 576 below the inner body 571. The extension 576 may have the rib connection portion 577 protruding downward from the surface.

[0166] Therefore, the rib connection portion 577 is circumferentially connected to the end of the frame support rib 575. It extends upward and then extends downward at an angle.

[0167] The reason why the rib connection portion 577 is inclined downward is that the filter mechanism 50 is attached to the main body 2. The filter mechanism 50 can be coupled and uncoupled in a rotational manner, and can be separated from the main body 2. This is to allow the filter mechanism 50 to rise during the process of releasing.

[0168] When the filter mechanism 50 is lifted during the separation process, The user can confirm that they are separated.

[0169] The filter mechanism 50 is rotated so that the filter mechanism 50 is released from the coupling state. When configured in this manner, a rotational force must be applied to the filter mechanism 50. The filter mechanism 50 can be prevented from being separated from the main body 20 even when pulled. Therefore, the filter mechanism 50 is prevented from being unintentionally separated from the main body 2. It can be prevented.

[0170] The rib connection portion 577 is a slot in which a fixing protrusion 229 of the flow guide 22, which will be described later, is accommodated. The slot 578 may be a groove or a hole.

[0171] The inner frame 501 extends downward at a lower surface 509 of the inner frame 501. The filter may further include a contact portion 509a. When the cover 570 and the inner frame 501 are joined together, the frame support rib The sides of 575 can be touched.

[0172] The inner frame 501 accommodates the fixing rib 228 formed on the flow guide 22. The recess 50 is recessed upward to form a rib receiving portion 579 for receiving the rib. It may contain 9b.

[0173] When the inner frame 501 is coupled to the filter cover 570, The recessed portion 509b is disposed above the connecting rib 577 and spaced apart from the connecting rib 577. do.

[0174] At this time, the flow guide 22 is fixed during the rotation and lowering of the filter mechanism 50. The rib 228 is accommodated in the rib accommodating portion 579 between the recessed portion 509b and the rib connecting portion 577. To accommodate this, the recessed portion 509b may be formed to be inclined.

[0175] Therefore, the rib receiving portion 579 also extends downwardly. 79 is understood to be the space between the inner frame 501 and the filter cover 570. That is, the fixing rib 228 of the flow guide 22 can be fixed to the inner frame 5. 01 and the filter cover 570.

[0176] The flow guide 22 includes a guide body 220 having openings at the top and bottom. The guide body 220 is configured to guide the air discharged from the second cyclone unit 130. The air passage may include a passage forming wall 222 for forming the first air passage 232 through which air flows. can.

[0177] The flow path forming wall 222 can protrude in the radial direction from the guide body 222. do.

[0178] At this time, the flow guides 22 are spaced apart in the circumferential direction so that the air can flow smoothly. A plurality of channel-forming walls 222 may be included.

[0179] The suction motor 20 is located inside the flow guide 22. In order to prevent this, the gap between the flow guide 22 and the suction motor 20 must be large. However, the gap between the flow guide 22 and the suction motor 20 must be large. If this is the case, there is a problem that the air flow performance will decrease.

[0180] However, as in the present invention, the flow path forming wall 222 protrudes from the guide body 220. Then, the flow path forming wall 222 ensures a sufficient cross-sectional area of ​​the flow path through which air can flow. , the air flow performance can be improved.

[0181] The upper part of the flow guide 22 can be accommodated inside the inner frame 501. Also, the flow path forming wall 222 is formed so as not to interfere with the filter mechanism 50. The forming wall 222 is formed at a position spaced apart from the upper end of the flow guide 22 downward at a predetermined interval. can be.

[0182] The outer diameter of the upper part of the guide body 220 is equal to that of the inner frame 501. Therefore, the filter mechanism 50 can be formed to have a smaller inner diameter than the inner diameter of the surrounding portion 503. When coupled to the main body 2, the upper portion of the flow guide 22 is accommodated in the filter mechanism 50. The inner sealing member 530 can be seated on the upper end of the flow guide 22. .

[0183] According to the present invention, a portion of the flow guide 22 is housed inside the filter mechanism 50. Therefore, the increase in height of the vacuum cleaner 1 can be minimized.

[0184] The guide body 220 has an inner peripheral surface on which a filter supporting the lower end of the pre-filter 29 is provided. The filter support portion 225 may be provided. It can protrude from the inner peripheral surface of the body 220.

[0186] The fastening portion 226 of the guide body 220 is seated on the upper motor housing 26. In this state, the fastening member S1 penetrates the fastening portion 226 from above, and then the upper motor The motor housing 26 can be fastened to the motor housing 26.

[0187] The fastening member S1 is fastened to the upper motor housing 26 and the lower motor housing After passing through the discharge guide 27, the discharge guide 28 can also be fastened. Since the assembly can be performed using a small number of fastening members, the structure and assembly method are simple. This has the advantage that

[0188] The flow guide 22 includes a securing rib 228 for coupling with the filter mechanism 50. The height of the filter mechanism 50 can be adjusted during the rotation of the filter mechanism 50. The fixing ribs 22 may variably extend in the circumferential direction and may extend in an inclined manner; and A fixing protrusion 229 may be formed on the lower surface of the fixing rib 22 .

[0189] Meanwhile, the flow path forming wall 222 may be formed with a reinforcing rib 227. 2 is spaced from the inner circumferential surface of the second body 12 to form the second air passage 234. obtain.

[0190] The reinforcing rib 227 extends from the flow path forming wall 222 toward the second body 12. obtain.

[0191] In this way, when the flow guide 22 is spaced apart from the inner circumferential surface of the second body 12, When an external force is applied from the outside of the second body 12, the second body 12 moves in the direction of the flow gas. There is a risk of it being transformed towards Ido 22.

[0192] However, according to the present invention, the flow path forming wall 222 is provided with a reinforcing rib 227, Therefore, even if an external force is applied to the second body 12, the second body 12 does not lose the reinforcing ring. The second body 12 comes into contact with the projection 227, so that deformation of the second body 12 can be restricted.

[0193] Since the flow path forming wall 222 protrudes from the guide body 220, the reinforcing rib 2 When the reinforcing rib 227 is formed on the flow path forming wall 222, the length of the reinforcing rib 227 can be reduced. It has the advantage of being able to

[0195] The process of assembling the filter mechanism 50 will be described with reference to FIGS. 15 and 16. I decided to do so.

[0196] In order to connect the filter mechanism 50 to the main body 2, A part of the side is accommodated in the second body 12.

[0197] As a result, the rib receiving portion 579 of the filter mechanism 50 and the fixing rib 228 are can be aligned.

[0198] In this state, when the filter mechanism 50 is rotated, the fixed rib 228 moves in the direction of the rib convergence. At this time, the fixing rib 228 is easily inserted into the rib receiving portion 579. The height of the rib receiving portion 579 is higher than the height of the fixing rib 228. can be formed.

[0199] Since the fixing rib 228 extends at an angle, the rotation of the filter mechanism 50 The filter mechanism 50 is then lowered by the fixing rib 228.

[0200] When the fixing rib 228 is received in the rib receiving portion 579, the fixing protrusion 229 When inserted into slots 578 of the rib joint 577, the filter mechanism 50 and the The connection with the main body 2, that is, the connection with the flow guide 22, is completed.

[0201] On the other hand, in order to separate the filter mechanism 50 from the main body 2, 50 is rotated in the other direction. At this time, the fixing rib 228 is formed to be inclined. Therefore, during the rotation of the filter mechanism 50, the filter mechanism 50 moves toward the fixing rib 22. 8, the fixed rib 228 is lifted from the rib receiving portion 579. When the filter mechanism 50 is removed from the main body 2, the filter mechanism 50 is released from the main body 2.

[0202] In this state, when the filter mechanism 50 is moved upward, the filter mechanism 50 It can be separated from the main body 2 .
