Figure 3 is a side view of the vacuum cleaner, and Figure 4 is a top view of a vacuum cleaner according to one embodiment of the present invention.

[0019] Figure 4 is a longitudinal cross-sectional view of a vacuum cleaner according to one embodiment of the present invention, and Figure 5 is an embodiment of the present invention. This is a cross-sectional view of a vacuum cleaner.

[0020] Referring to Figures 1 to 5, the vacuum cleaner 1 according to one embodiment of the present invention includes a main body 2. It is possible.

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

[0022] The vacuum cleaner 1 may further include a handle portion 3 that is connected to the main body 2. The handle portion 3 may be located on the opposite side of the suction portion 5 in the main body 2.

[0023] In other words, the main body 2 can be positioned between the intake portion 5 and the handle portion 3.

[0024] The main body 2 comprises a first body 10 and a second body located above the first body 10. It can include 'i12'.

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

[0026] Furthermore, the central part of the intake section 5 is roughly the first body 10 and the second body 1 The suction portion 5 can be connected to the main body 2 so as to be located at the boundary with 2.

[0027] The main body 2 includes a dust separation unit that separates dust from the air drawn in through the intake unit 5. It can also include more.

[0028] The dust separation unit can separate dust by, for example, cyclone flow. It may include a cyclone section 110. In this case, the first body 10 is the first Includes cyclone section 110.

[0029] The air and dust drawn in through the intake section 5 are directed to the inner surface of the first cyclone section 110. It will flow in a spiral pattern along that line.

[0030] The axis of cyclone flow in the first cyclone section 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. It may further include a second cyclone section 130 that separates the dust. To minimize the size, the second cyclone section 130 is located above the first cyclone section 18 It may be located inside 0. The second cyclone section 130 is composed of multiple cyclones arranged in parallel. It can include a body.

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

[0033] The first body 10 stores dust separated from each of the cyclone sections 110 and 130. It serves as a dust container. The main body 2 opens and closes the lower part of the first body 10. The body cover 16 may further include a body cover 16. The body cover 16 rotates The first body 10 can be opened and closed.

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

[0035] The first body 10 contains a storage area for dust separated from the second cyclone section 130. A dust storage guide 124 may be provided. The dust storage guide 124 is the 2. Connected to the lower side of the cyclone section 130 and in contact with the upper surface of the body cover 16. It is possible.

[0036] The dust storage guide 124 provides space inside the first body 10 for the first cycle The first dust storage section 121 stores the dust separated from the ron section 110, and the second cycle The structure is divided into a second dust storage section 123 where dust separated from the ron section 130 is stored. can.

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

[0038] At least a portion of the dust storage guide 124 is such that its diameter decreases from top to bottom. It can be formed as follows. For example, a part of the upper part of the dust storage guide 124 goes downwards It can be formed so that its diameter decreases.

[0039] Furthermore, the dust storage guide 124 extends downward from the upper end of the dust storage guide 124. The structure may include a shatterproof rib 124a. The shatterproof rib 124a is, for example, It is formed in a cylindrical shape and can surround the upper part of the dust storage guide 124.

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

[0041] The cyclone flow can flow downward along the inner circumferential surface of the second body 10. In the process of the cyclone flow descending, the cyclone flow is the body cover -16 comes into contact with the first dust, which can change the rotational flow into an upward flow. If upward flow exists within the storage section 121, the dust stored in the first dust storage section 121 There is a problem in that the material is scattered and flows back into the second cyclone section 130.

[0042] In the present invention, the upward flow within the first dust storage section 121 is controlled by the dust prevention rib 124a The space between the dust storage guide 124 and the upper part of the dust storage guide 124 is controlled by the dust prevention rib 124a The flow changes to a downward flow again, preventing the dust stored in the first dust storage unit 121 from scattering. This prevents the problem of dust flowing back into the second cyclone section 130. .

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

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

[0045] The vacuum cleaner 1 includes a suction motor 20 for generating suction force, and power to the suction motor 20. It may further include a battery 40 for supplying power.

[0046] The intake motor 20 may be located within the second body 12. At least a portion of the 20 may be located above the dust separation section. Therefore, the suction motor The -20 may be located above the first body 10.

[0047] The suction motor 20 can communicate with the discharge port of the second cyclone section 130. .

[0048] For this purpose, the main body 2 is connected to the second cyclone section 130 by a discharge guide 28 The system may further include a flow guide 22 that communicates with the discharge guide 28.

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

[0050] Furthermore, at least a portion of the suction motor 20 is located inside the flow guide 22. obtain.

[0051] Therefore, the axis of the cyclone flow in the first cyclone section 180 is the suction motor 2 It is possible to penetrate 0.

[0052] When the intake motor 20 is located above the second cyclone section 130, the second cyclone section The air discharged from the chlorine unit 130 can immediately flow towards the suction motor 20. Therefore, the flow path between the dust separation unit and the suction motor 20 can be minimized.

[0053] The intake motor 20 may include a rotating impeller 200. The ra 200 can be connected to the shaft 202. The shaft 202 extends in the vertical direction. It will be placed there.

[0054] Then, the impeller 200 is positioned on the upper side of the intake motor 20. A motor 20 may be positioned. In this case, the air is drawn by the impeller 200 into the intake motor It can flow from above to below the 20.

[0055] The extension of the shaft 202 (which can also be called the rotation axis of the impeller 200) is the first body It can pass through the 10. At this time, the rotation shaft of the impeller 200 and the dust The axis of the cyclone flow generated from the first cyclone section 110 of the separation section may be located on the same line as the axis of the cyclone flow. ru.

[0056] According to the present invention, the air discharged from the dust separation unit, i.e., the second cyclone unit 1 The path through which the air discharged upward from 30 flows towards the intake motor 20 is reduced, and the air Because the change in direction is reduced, it has the advantage of reducing airflow losses.

[0057] When airflow loss decreases, the suction force increases, and power is supplied to the suction motor 20. The battery life can be increased by 40.

[0058] The vacuum cleaner 1 has an upper motor housing that covers a portion of the upper part of the suction motor 20. 26 and the lower motor housing 27 which covers a part of the lower side of the intake motor 20 It can be included in these.

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

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

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

[0062] According to the present invention, a single flow guide 22 has a first air passage 232 and a second air passage 234 This allows for the formation of a simpler structure by reducing the number of parts required to form each airflow channel. It has the advantage of becoming [something].

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

[0064] The air discharged from the second cyclone section 130 flows along the first air passage 232 The air that flows into the intake motor 20 and is discharged from the intake motor 20 is the second air After flowing along the flow path 234, it is discharged to the outside. Therefore, the second air flow path 23 Number 4 serves as the exhaust passage.

[0065] The handle portion 3 comprises a handle 30 for the user to grip, and the lower part of the handle 30 It may include a battery housing 410 located therein.

[0066] The handle 30 may be located behind the intake motor 20.

[0067] To define the direction, in the vacuum cleaner 1, the direction is forward relative to the suction motor 20. The direction in which the intake portion 5 is located is forward, and the direction in which the handle 30 is located is backward. .

[0068] The battery 40 may be located at the rear of the first body 10. The suction motor 20 and the battery 40 are arranged so as not to overlap in the vertical direction, and the arrangement height They can be arranged in a completely different way.

[0069] According to the present invention, the heavier suction motor 2 is used as a reference to 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 Because it is located downwards, the weight of the vacuum cleaner 1 is evenly distributed throughout. When using the Handle 30 to clean, strain on the user's wrist can be prevented. In other words, the heavier components are distributed and positioned at the front and rear of the vacuum cleaner 1, and are different from each other. Because it is positioned at a certain height, it is possible to prevent the center of gravity of the vacuum cleaner 1 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 it is located in front of the handle 30, there is no structure above the handle 30. In other words, the upper surface of the handle 30 forms a part 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, one component of the vacuum cleaner 1 is used by the user. Contact with the arm can be prevented.

[0072] The handle 30 has a first extension 310 that extends vertically and can be grasped by the user. And, a second extension 3 extends from the upper side of the first extension 310 toward the intake motor 20. It may include 20. The second extension 320 may extend horizontally in at least a portion of it. ru.

[0073] The first extension 310 is such that when the user grasps the first extension 310, the hand 1. Movement control to prevent movement of extension 310 in the longitudinal direction (vertical direction in Figure 2) A limiting portion 312 may be provided. The movement limiting portion 312 is located from the first extension portion 310. It may extend toward the intake portion 5.

[0074] The movement limiting portion 312 is positioned at a distance from the second extension portion 320. Therefore, With the first extension 310 being grasped, some fingers are positioned above the movement-restricting portion 312. The remaining fingers may be positioned below the movement-restricting portion 312.

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

[0076] With this arrangement, the suction part The longitudinal axis A1 of part 5 can pass through the user's wrist.

[0077] When the longitudinal axis A1 of the suction part 5 passes through the user's wrist, the user's arm is extended. The longitudinal axis A1 of the suction portion 5 can be substantially aligned with the extension direction of the user's arm. Therefore, in this state, the user can grasp the handle 30 and use the vacuum cleaner 1 It has the advantage of minimizing the user's force required when pushing or pulling.

[0078] The handle 30 may include an operating section 326. For example, the operating section 32 6 may be located on the inclined surface formed on the second extension 320. Through the operating section 326 On and off commands for the vacuum cleaner's suction motor can be input.

[0079] The operating unit 326 may be positioned to face the user. With the handle 30 as a reference The operating unit 326 may be located on the opposite side of the movement limiting unit 312.

[0080] The operating unit 326 may be positioned higher than the movement limiting unit 312. Therefore, the user With the first extension 310 in grasp, the operating unit 326 can be easily operated with the thumb. It is possible.

[0081] Furthermore, since the operating section 326 is located at a position separate from the first extension 310, When cleaning is performed while gripping the first extension 310, the operating part 326 may be operated unintentionally. This can be prevented.

[0082] The second extension 320 may include a display unit 322 for displaying the operating status. The display unit 322 may, for example, be located on the upper surface of the second extension unit 320. In the process of cleaning, the user sees the display unit 322 located on the upper surface of the second extension 320. It can be easily checked. The display unit 322 shows, for example, the remaining charge of the battery 40. It can display information such as the strength of the suction motor.

[0083] The display unit 322 may include, but is not limited to, a plurality of light-emitting units. The light-emitting parts may be arranged spaced apart along the length of the second extension 320.

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

[0085] The battery 40 may be detachably coupled to the battery housing 410. As an example, the battery 40 is located below the battery housing 410. It can be inserted inside the Terry housing 410.

[0086] The rear surface of the battery housing 410 and the rear surface of the first extension 310 are continuous. A surface can be formed. Therefore, the battery housing 410 and the first extension The long section 310 can be integrated with the other section.

[0087] With the battery 40 housed in the battery housing 410 The lower surface of Lee 40 can be exposed to the outside. Therefore, when the vacuum cleaner 1 is placed on the floor... The battery 40 may be placed on the floor.

[0088] With this structure, the battery 40 is removed from the battery housing 410. It has the advantage of being able to be separated immediately.

[0089] Furthermore, since the lower surface of the battery 40 is exposed to the outside, the lower surface of the battery 40 The vacuum cleaner 1 can be in direct contact with the outside air, which can improve the cooling performance of the battery 40.

[0090] On the other hand, referring to Figure 3, the vacuum cleaner 1 discharges air that has passed through the suction motor 20. The filter mechanism 50 having an air outlet 522 may further be included. The outlet 522 includes, for example, multiple openings, which may be arranged circumferentially. Therefore, the air outlets 522 can be arranged in a ring shape.

[0091] The filter mechanism 50 can be detachably coupled to the upper side of the main body 2. The turn 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 It may be located outside the second body 12. Therefore, one of the filter mechanisms 50 The part is drawn into the interior of the main body 2 through the upper opening of the main body 2, and the other part is in the main body 2 It protrudes from the 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 above the main body 2, allowing the user to operate the filter machine The filter mechanism 50 can be easily separated while holding the structure 50.

[0094] With the filter mechanism 50 coupled to the main body 2, the filter mechanism 50 The air outlet 522 may be located on the side. Therefore, the air discharged from the intake motor 20 The air is discharged upwards from the main body 2.

[0095] According to this embodiment, during the process of cleaning using the vacuum cleaner 1, air is discharged from the air outlet 522. This can prevent the released air from flowing towards the user.

[0096] The main body 2 is a filter for filtering the air flowing into the intake motor 20. A filter 29 may be further included. The pre-filter 29 is connected to the flow guide 22 It may be located inside. Also, the pre-filter 29 is securely attached to the upper motor housing 26. It can be attached and surround a part of the upper motor housing 26. That is, the upper The motor housing 26 has a filter support portion for supporting the pre-filter 29. It can include.

[0097] With the filter mechanism 50 attached to the main body 2, the filter mechanism 50 is To prevent the pre-filter 29 from moving, pressurize the pre-filter 29. It is possible.

[0098] As an example, the filter mechanism 50 pressurizes the pre-filter 29 downwards. This is possible. Therefore, according to the present invention, a structure for fixing the pre-filter 29 It has the advantage of not requiring [something].

[0099] Figure 6 shows a filter mechanism according to one embodiment of the present invention separated from the main body. Yes, Figure 7 is a view of the lower side of the filter mechanism according to one embodiment of the present invention, and Figure 8 is, Figure 7 is an exploded perspective view of the filter mechanism, and Figure 9 is a cross-sectional perspective view of the filter mechanism in Figure 7. That is the case.

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

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

[0102] Since the impeller 200 is positioned above the intake motor 20, The upper motor housing is positioned so that the pre-filter 29 covers the impeller 200. It can be arranged around 26.

[0103] Therefore, when the filter mechanism 50 is separated from the main body 2, the prefix The filter 29 can be exposed to the outside, thereby allowing the pre-filter 29 to be separated. To enter a state of incapacitation.

[0104] The pre-filter 29 may include a knob 29a. The user is exposed to the outside. Grasp the knob 29a of the pre-filter 29 and hold the pre-filter 29 upwards. The pre-filter 29 can be lifted up and separated from the main body 2. Since the filter 29 can be separated from the main body 2, the user can easily remove the pre-filter 29. It can be cleaned.

[0105] The filter mechanism 50 filters the air discharged from the intake motor 20. A filter 560 for this purpose and a filter frame that supports the filter 560 are provided. It can be included in these.

[0106] The filter 560 is, for example, a HEPA filter (high efficiency (y particulate air filter: HEPA filter) .

[0107] With the filter mechanism 50 connected to the main body 2, the height of the vacuum cleaner 1 increases. To prevent this, the filter 560 may be positioned to surround the flow guide 22. ru.

[0108] That is, the filter 560 is formed in a ring shape as an example, and the filter A portion of the flow guide 22 may be located within the region formed by -560.

[0109] Furthermore, at least one of the pre-filters 29 is located in the region formed by the filter 560. The part can be accommodated. That is, the filter 560 surrounds the pre-filter 29.

[0110] The filter frame is inserted between the second body 12 and the flow guide 22. In this state, it can be coupled to the flow guide 22.

[0111] The filter frame comprises an inner frame 501 and an inner frame 501 surrounding It may include an outer frame 540 that is positioned in such a manner.

[0112] The outer circumferential surface of the inner frame 501 and the inner circumferential surface of the outer frame 540 are separated. The filter 5 60 could be located there.

[0113] The filter frame has the air outlet 522 formed therein, and the filter 560 An exhaust grille 520 covers the upper side, and a filter 560 covers the lower side. It may further include a router cover 570.

[0114] Specifically, the inner frame 501 has an upper surface portion 502 and a frame of the upper surface portion 502 It may include a peripheral portion 503 that extends downward.

[0115] The surrounding portion 503 comprises a first portion 503a and an extension extending downward from the first portion 503a, The first part 503a may include a second part 503b having a larger diameter than the first part 503a.

[0116] The difference in diameter between the first portion 503a and the second portion 503b causes the first portion 50 Between 3a and the second portion 503b is a mounting portion for securing the exhaust grille 520. 506 may be formed.

[0117] The anchoring portion 506 is located at a position separated downward from the upper surface portion 502 and relative to the surrounding portion 503. It is formed along the circumferential direction.

[0118] The exhaust grille 520 can be attached to the attachment portion 506. It can be formed in a ring shape. The inner diameter of the exhaust grille 520 is the surrounding portion 50 The outer diameter of the first part 503a of 3 may be the same as or larger than that of the first part 503a. And the fixing part 506 The outer diameter of the first part and the outer diameter of the second part 503b are larger than the inner diameter of the exhaust grille 520. That's good too.

[0119] Therefore, the upper surface portion 502 and the first portion of the surrounding portion 503 of the inner frame 501 With part 503a passing through the exhaust grille 520, the exhaust grille 520 is the fixing part It can be safely landed at 506.

[0120] The filter mechanism 50 is an inner filter that is coupled to the frame of the inner frame 501. The inner lever member 510 may further include a ring-shaped member. It is possible.

[0121] The inner lever member 510 is a hook for connecting to the inner frame 501 It can be equipped with Ku 512.

[0122] The inner frame 501 has hook coupling holes for which the hook 512 is attached. 508 can be formed.

[0123] The hook coupling hole 508 may be formed in the first portion 503a of the surrounding portion 503. Furthermore, the first portion 503a of the surrounding portion 503 has the hook 512 connected to the hook coupling hole 5 A guide groove 507 may be formed to guide to 08. The guide groove 507 extends in the vertical direction. obtain.

[0124] Therefore, the hook 512 of the inner lever member 510 follows the guide groove 507 When moved and aligned with the hook coupling hole 508, the hook 512 will be positioned in the hook coupling hole It can be inserted into 508.

[0125] The exhaust grille 520 is secured to the attachment portion 506 of the inner frame 501. The inner lever member 510 can then be connected to the inner frame 501.

[0126] For this purpose, the inner circumferential surface of the exhaust grille 520 has the feet of the inner lever member 510 A guide groove 524 may be formed to provide space for the K 512 to move. 24 can extend vertically.

[0127] Therefore, the hook 512 of the inner lever member 510 is connected to the inner frame 5 Movement along the guide groove 507 of 01 and the guide groove 524 of the exhaust grille 520 can.

[0128] With the inner lever member 510 connected to the inner frame 501, The inner lever member 510 can be attached to the upper surface of the exhaust grille 520.

[0129] Therefore, according to this embodiment, the exhaust grille 520 is positioned on the inner frame 501 It has the advantage of not requiring any separate means of securing it in place.

[0130] The outer frame 540 can support the exhaust grille 520. The outer frame 540 is in contact with the lower surface of the exhaust grille 520, and as an example, melting It can be fixed to the exhaust grille 520 by attachment. However, in the present invention, the exhaust grille 52 It is clear that there are no restrictions on the method of fixing 0 to the outer frame 540. .

[0131] The outer frame 540 supports the exhaust grille 520, The frame 540 may have attachment grooves 544 formed therein for securing the exhaust grille 520. ru.

[0132] When the outer frame 540 is fixed to the exhaust grille 520, the outer frame A filter housing space is formed between the frame 550 and the surrounding portion 503 of the inner frame. The filter 560 can be housed in the filter housing space. With the filter 560 housed in the filter housing space, the filter 560 is exposed to the air. It overlaps with the outlet 522 in the vertical direction.

[0133] The filter mechanism 50 is an outer deco part coupled to the outer frame 540. Material 550 may be further included. The outer decorative member 550 is the exhaust grille 5 It can be connected to the outer frame 540 by surrounding a portion of the 20. The tardeco member 550 can surround the upper part of the outer frame 540. The lower end of the outer decorative member 550 is attached to the outer circumferential surface of the outer frame 540. A bonding surface 546 can be formed for this purpose.

[0134] The inner circumferential surface of the outer decorative member 550 is connected to the outer frame 540. One or more connecting protrusions 554 are formed on the outer circumferential surface of the outer frame 540. One or more coupling grooves 542 can be formed to accommodate one or more coupling protrusions 554. ru.

[0135] The outer circumferential surface of the outer decorative member 550 allows the user to separate the filter mechanism 50. Alternatively, when joining them, they may be equipped with an anti-slip part 552 to prevent the hands from slipping. Yes, it is possible. The anti-slip portion 552 is, for example, located on the outer surface of the outer decorative member 550. It could be multiple protruding projections.

[0136] Multiple anti-slip parts 552 are provided to effectively prevent the user's hand from slipping. The outer deco member 550 may be arranged at intervals along its circumferential direction.

[0137] The filter cover 570 is formed, for example, in a ring shape, so that air can pass through. It can include an opening of 574.

[0138] The filter cover 570 is made of the outer frame 540 and the inner frame It can cover the filter 560 housed between 501 and 501.

[0139] The filter cover 570 is located on the lower surface of the outer frame 540 and the inner frame The lower surface of the frame 501 can be supported, and the outer frame 540 and the inner The frame 501 can be joined to each other, for example, by fusion.

[0140] The filter mechanism 50 is in the state where the filter mechanism 50 is coupled to the main body 2. Sealing members 530, 58 for sealing the filter mechanism 50 and the main body 2 It can also contain zeros.

[0141] Figure 10 shows a cross-section of the filter mechanism according to one embodiment of the present invention, coupled to the main body. This is a diagram.

[0142] Referring to Figures 9 and 10, the sealing members 530 and 580 are the flow guides Air inside the do 22 passes through the hook coupling hole 508 provided in the inner frame 501. Inner sealing member 530 (or first sealing member) to prevent leakage to the outside It may include a ring component.

[0143] The inner sealing member 530 is located around the inner frame 501. It can be bonded to the inside.

[0144] Specifically, a sealing rib 50 extends downward from the upper surface portion 502 of the inner frame 501. 4 may extend. The sealing rib 504 is the surrounding portion 50 of the inner frame 501. It can be separated from 3. The sealing rib 504 is in the circumferential direction of the upper surface portion 501. It can be formed in succession.

[0145] Therefore, the sealing rib 504 and the surrounding portion 503 of the inner frame 501 A space is formed between the inner sealing member 530 for housing the front A portion of the inner sealing member 530 is fitted into the aforementioned space.

[0146] With the inner sealing member 530 connected to the inner frame 501 The inner sealing member 530 is located on the lower surface of the first portion 503a of the surrounding portion 503 and , it contacts the inner circumferential surface of the second portion 503b and the lower surface of the sealing rib 504.

[0147] Then, when the filter mechanism 50 is coupled to the main body 2, the inner sealant The guide member 530 is fixed to the upper end of the flow guide 22.

[0148] Therefore, according to the present invention, the inner sealing member 230 is the surrounding portion 503 The lower surface of the first portion 503a, the inner circumferential surface of the second portion 503b and the sealing rib 50 Since it is attached to the upper end of the flow guide 22 while in contact with the lower surface of 4, the flow guide This prevents the air flowing through the 22 from flowing into the hook coupling hole 508.

[0149] Furthermore, the inner sealing member 230 allows the outer circumferential surface of the flow guide 22 to be in contact with the front This prevents air from leaking into the gap between the inner frame 501 and the inner surface of the surrounding part 503. It can be stopped.

[0150] For the filter mechanism 50 to be separated from the main body 2, the filter mechanism 5 A gap may occur between the outer surface of 0 and the inner circumferential surface of the second member 12.

[0151] The sealing members 530 and 580 allow the air in the second air passage 234 to filter the air. - The gap between the outer frame 540 and the second body 12 without passing through 560 Outer sealing member 580 (or second sealing member) to prevent flow It may further include a ring member.

[0152] The outer sealing member 580 may be coupled to the frame of the filter cover 570. The outer sealing member 580 is not limited to the filter cover 57. It is fitted and coupled to 0, or the filter cover 570 is inserted and injected into it. It can form in the body.

[0153] Since the outer sealing member 580 is supported on the inner circumferential surface of the second member 12 A support surface 125 can be formed. The support surface 125 is a portion of the thickness of the second portion 12. It can be formed by the enlargement of [something].

[0154] When the filter mechanism 50 is coupled to the main body 2, the outer sealing member 5 80 can be fixed to the support surface 125.

[0155] Therefore, the air in the second air passage 234 is connected to the outer frame 540 and the second Flow into the gap between the inner circumferential surface of member 12 can be prevented.

[0156] On the other hand, when the filter mechanism 50 is coupled to the main body 2, the outer decorative member 5 50 is attached to the upper side of the second body 12 of the main body 2. Therefore, the user With the outer decorative member 550 in place, rotate the filter mechanism 50 in one direction. The filter mechanism 50 can be separated from the main body 2.

[0157] Then, with the filter mechanism 50 coupled to the main body 2, the filter 5 A portion of 60 may be located inside the main body 2, while another portion may be located outside the main body 2.

[0158] According to the present invention, a part of the filter mechanism 50 protrudes from the outside of the main body 2. This allows the user to grasp the filter mechanism 50, and the outside of the main body 2 Since the filter 560 can also be positioned on the protruding portion, the filter 5 The size can be increased by 60. Therefore, 56 filters can come into contact with the air. An increase in the area of ​​zero can improve air purification performance.

[0159] Figure 11 is a perspective view of a filter cover according to one embodiment of the present invention, and Figure 12 is a perspective view of Figure 1 Figure 13 is a cross-sectional view showing how the inner frame is attached to the filter cover of 1. Figure 14 is a perspective view of a flow guide according to one embodiment of the present invention. This is a plan view of the flow guide.

[0160] Referring to Figures 10 to 14, the filter cover 570 is an inner body 571, an outer body 572 separated from the inner body 571, and the inner A connecting body 573 connects the inner body 571 and the outer body 572. It can include.

[0161] The inner body 571 and the outer body 572 are each shaped like a ring. It is possible.

[0162] The connecting body 573 is provided with one or more openings 574 for air to pass through. It is possible.

[0163] The inner circumferential surface of the inner body 571 is the lower surface 509 of the inner frame 501. The frame may be provided with multiple frame support ribs 575 for support. The frame support rib 575 may be arranged at circumferential distances from the inner body 571. .

[0164] The inner circumferential surface of the inner body 571 has ribs for connection with the flow guide 22. It can be equipped with a connecting portion 577.

[0165] The inner body 571 extends so that the rib joint portion 577 extends with a downward inclination. It may include an elongated portion 576. The extension 576 is below the inner body 571. The extension portion 576 may protrude downwards and be equipped with the rib connecting portion 577.

[0166] Therefore, the rib joint portion 577 is circumferentially at the end of the frame support rib 575. extends downward and extends in an inclined manner downward.

[0167] The reason why the rib coupling portion 577 slopes downward is that the filter mechanism 50 is coupled to the main body 2 in a rotatable manner for coupling and decoupling, and in the process of separating the filter mechanism 50 from the main body 2 to allow the filter mechanism 50 to rise.

[0168] When the filter mechanism 50 rises during the separation process, the user can confirm that the filter mechanism 50 is separated.

[0169] When the filter mechanism 50 is configured to be decoupled during the rotation process of the filter mechanism 50 a rotational force must be applied to the filter mechanism 50, so even if the filter mechanism 50 is pulled, it can be prevented from being separated from the main body 20. Therefore, it can be prevented that the filter mechanism 50 is inadvertently separated from the main body 2.

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

[0171] The inner frame 501 may further include a contact portion 509a that extends downward at the lower surface 509 of the inner frame 501. The contact portion 509a can contact the side surface of the frame support rib 575 in a state where the filter cover 570 and the inner frame 501 are coupled.

[0172] The inner frame 501 has a fixing rib 228 formed on the flow guide 22 accommodated​​​​​ A recessed portion 50 formed to be recessed upward to form a rib accommodating portion 579 for accommodation. 9b may be included.

[0173] In a state where the inner frame 501 is coupled to the filter cover 570, the recessed portion 509b is disposed above and spaced apart from the coupling rib 577. to be.

[0174] At this time, during the rotation and downward movement of the filter mechanism 50, the fixing rib 228 of the flow guide 22 can be accommodated in the rib accommodating portion 579 between the recessed portion 509b and the rib coupling portion 577. The recessed portion 509b may be formed to be inclined so that.

[0175] Therefore, the rib accommodating portion 579 also extends so as to be inclined downward. The rib accommodating portion 5 79 can be understood as 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 sandwiched between the inner frame 5 01 and the filter cover 570.

[0176] The flow guide 22 may include a guide body 220 having openings at the upper and lower portions. The guide body 220 may include a flow path forming wall 222 for forming the first air flow path 232 through which the air discharged from the second cyclone portion 130 flows. can be. to be.

[0177] The flow path forming wall 222 can project radially in the guide body 222. to be.

[0178] At this time, so that air can flow smoothly, the flow guide 22 is spaced apart in the circumferential direction. It can include multiple channel-forming walls 222.

[0179] The suction motor 20 is located inside the flow guide 22, but the size of the main body 2 is For it not to increase, the gap between the flow guide 22 and the suction motor 20 must be large. No. However, the gap between the flow guide 22 and the suction motor 20 must be large. This leads to a problem where the airflow performance deteriorates.

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

[0181] The upper part of the flow guide 22 can be housed inside the inner frame 501. Also, the flow channel forming wall 222 is not interfered with by the filter mechanism 50, The forming wall 222 is formed at a position that is spaced at a constant distance below the upper end of the flow guide 22. It can be done.

[0182] Furthermore, the outer diameter of the upper part of the guide body 220 is the same as that of the inner frame 501. It can be formed smaller than the inner diameter of the surrounding portion 503. Therefore, the filter mechanism 50 is in front When connected to the main body 2, the upper part of the flow guide 22 fits into the filter mechanism 50. The inner sealing member 530 can be attached to the upper end of the flow guide 22. .

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

[0184] On the inner peripheral surface of the guide body 220, a filter support portion 225 for supporting the lower end of the pre-filter 29 can be provided. The filter support portion 225 can project from the inner peripheral surface of the guide body 220. At the lower end of the guide body 220, a fastening portion 226 for fastening to the motor housings 26 and 27 can be provided.

[0185] The fastening portion 226 of the guide body 220 can be seated on the upper motor housing 26. In this state, after the fastening member S1 penetrates the fastening portion 226 from above, it can be fastened to the upper motor housing 26.

[0186] After passing through the fastening portion 226 from above, the fastening member S1 can penetrate the upper motor housing 26 and the lower motor housing 27 and then be fastened to the discharge guide 28. According to such a structure, it can be assembled using a small number of fastening members, so there is an advantage that the structure and the assembly method are easy.

[0187] The flow guide 22 can include a fixing rib 228 for coupling with the filter mechanism 50. The fixing rib 22 can extend in the circumferential direction and be inclined so that the height of the filter mechanism 50 varies during the rotation process of the filter mechanism 50. And a fixing protrusion 229 can be formed on the lower surface of the fixing rib 22.

[0188] On the other hand, a reinforcing rib 227 can be formed on the flow path forming wall 222. The flow guide 22 is spaced apart from the inner peripheral surface of the second body 12 to form the second air flow path 234.

[0189] obtain.

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

[0191] Thus, when the flow guide 22 is separated from the inner circumferential surface of the second body 12, When an external force is applied to the second body 12 from the outside, the second body 12 moves the fluid gas There is a risk that it will be transformed towards Id 22.

[0192] However, according to the present invention, reinforcing ribs 227 are formed on the flow channel forming wall 222. Therefore, even if an external force is applied to the second body 12, the second body 12 will not be affected by the reinforcing This will result in contact with the b 227, which may limit the deformation of the second body 12.

[0193] Since the flow channel forming wall 222 protrudes from the guide body 220, the reinforcing rib 2 When 27 is formed in the flow channel forming wall 222, the length of the reinforcing rib 227 is reduced. It has the advantage of being able to do that.

[0194] Figure 15 shows the state of the filter mechanism according to one embodiment of the present invention before it is coupled to the flow guide. Figure 16 shows a filter mechanism according to one embodiment of the present invention, coupled to a flow guide. This is a diagram showing the state after the procedure.

[0195] The coupling process of the filter mechanism 50 will be described with reference to Figures 15 and 16. I've decided to do that.

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

[0197] As a result, the rib housing portion 579 of the filter mechanism 50 and the fixing rib 228 They can be lined up.

[0198] When the filter mechanism 50 is rotated in this state, the fixing rib 228 moves into the rib socket. It is housed in the container 579. At this time, the fixing rib 228 is easily housed in the rib housing 579. In order to accommodate, the height of the rib housing portion 579 is higher than the height of the fixed rib 228. It can be formed.

[0199] Since the fixed rib 228 extends in an inclined manner, the rotation process of the filter mechanism 50 The filter mechanism 50 will then be lowered by the fixing rib 228.

[0200] During the process in which the fixing rib 228 is housed in the rib housing portion 579, the fixing projection 229 When inserted into the slot 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, the filter mechanism Rotate 50 in the other direction. At this time, the fixing rib 228 is formed to be inclined. Therefore, during the rotation process of the filter mechanism 50, the filter mechanism 50 moves the fixed rib 22 It will rise due to 8. And the fixed rib 228 is the rib housing portion 579 When it is released, the connection between the filter mechanism 50 and the main body 2 is released.

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

[0203] Figure 17 shows the structure of the motor housing and second body according to one embodiment of the present invention. be.

[0204] Referring to Figures 5 and 17, the lower motor housing 27 is located in the second body 12 It can be formed as an integral part of it.

[0205] Air flowing along the discharge guide 28 passes through the lower motor housing 27. A through hole 273 can be formed for this purpose.

[0206] The lower motor housing 27 can support the upper motor housing 26. At this time, between the lower motor housing 27 and the upper motor housing 26 It can be equipped with a first sealer 274.

[0207] The lower motor housing 27 receives the air discharged from the intake motor 20. It may further include an air guide 272 for guiding into the air passage 234.

[0208] The upper motor housing 27 can support the flow guide 22. A second sealer 274 is provided between the upper motor housing 27 and the flow guide 22. It is possible.

[0209] The upper motor housing 26 also passes through the through hole 273 of the lower motor housing 27. A through-hole 262 may be formed through which the passed air can pass.

[0210] Figure 18 is a longitudinal cross-sectional view showing the airflow inside a vacuum cleaner according to one embodiment of the present invention. Figure 19 is a cross-sectional view showing the airflow inside a vacuum cleaner according to one embodiment of the present invention. .

[0211] The airflow in the vacuum cleaner 1 will be explained with reference to Figures 17 to 19.

[0212] When the suction motor 20 is operated, the air and dust drawn in through the suction section 5 are The material flows along the inner circumferential surface of the first cyclone section 110 and separates from each other.

[0213] The dust, separated from the air, flows downward and is stored in the first dust storage unit 121. The air separated from the dust flows into the second cyclone section 130. The air flowing into section 130 is separated from the dust again.

[0214] The dust separated from the air in the second cyclone section 130 flows downward and the second dust It is stored in the storage unit 123. Meanwhile, the air separated from the dust in the second cyclone unit 130 The gas is discharged from the second cyclone section 130 and rises towards the intake motor 20.

[0215] The air discharged from the second cyclone section 130 flows along the discharge guide 28. After passing through the through hole 273 of the lower motor housing 27, into the flow guide 22 The air rises along the first air passage 232. The air in the first air passage 232 It passes through pre-filter 29.

[0216] The air that has passed through the pre-filter 29 is directed to the intake motor inside the upper motor housing 27. The air passes through the 20. The air is then passed through the inside of the intake motor 20 by the impeller 200. After flowing, it is discharged into the lower motor housing 28. The air discharged to the 28 is redirected by the air guide 272 and the 2 It flows into the air passage 234.

[0217] Then, the air flowing through the second air passage 234 passes through the filter 560. Afterward, it is discharged to the outside through the air outlet 522.

[0218] According to the present invention, the airflow channel is formed only in the main body 2, and the handle portion 3 is shaped It is not done. Therefore, when connecting the handle part 3 to the main body 2, the handle part A sealing structure is not required at the boundary between 3 and the main body 2. Therefore, hand The structure for connecting part 3 to the main body 2 is simplified, and the advantage is that the connection is easy. There is.

[0219] Figure 20 shows a battery according to one embodiment of the present invention separated from the battery housing. Figure 21 is a perspective view of a battery according to one embodiment of the present invention. Figure 22 shows a coupling groove for a battery housing according to one embodiment of the present invention.

[0220] Referring to Figures 20 to 14, the battery 40 is a battery not shown. The battery may include a cell and a frame 450 that protects the battery cell.

[0221] A protrusion 460 is formed on the upper side of the frame 450, and a terminal 46 is attached to the protrusion 460. 2 may be placed there.

[0222] The battery 40 may further include a plurality of coupling parts 470, 480. Multiple connecting parts 470, 480 are connected to a first connecting part 47 located on one side of the frame 450. It may include 0 and a second connecting portion 480 located on the other side of the frame 450. The first joint 470 and the second joint 480 may, for example, be located on opposite sides of each other. ru.

[0223] The first coupling portion 470 may be a hook that is rotatably coupled to the frame 450. ru.

[0224] The first coupling portion 470 is, for example, connected to the battery housing The hinge joint 420 can be connected while housed in 410. The connector part 420 can also be called the battery connector part.

[0225] The hinge joint 420 has a locking mechanism for locking a part of the first joint 470. B422 may be formed.

[0226] As another example, the hinge joint 420 is integrally formed with the battery housing 410. It is also possible for the battery housing 410 itself to have the locking rib 422 It is also possible for this to be formed.

[0227] The second joint portion 480 is formed integrally with the frame 450 and elastically changes in response to external forces. It can be a hook that can be shaped.

[0228] The lower side of the battery housing 410 is for inserting the battery 40. An opening 411 is formed. The battery 40 is housed in the battery housing 410. In order to enable operation of the second coupling portion 480 in this state, the second coupling portion 480 is externally An exposed opening 415 can be formed for exposure to the elements.

[0229] Furthermore, in the battery housing 410, above the exposed opening 415, A coupling groove 416 can be formed for the coupling of the second coupling portion 480.

[0230] With the battery 40 housed in the battery housing 410, the dust Between the container 50 and the first joint 470 is a space for operating the first joint 470. 430 is formed.

[0231] Therefore, the user inserts their finger into the space 430 and the first connecting portion 470 and the The locking rib 422 can be released. Also, the user can access the battery housing. The second coupling portion 480 exposed on the outside of the zing 410 is operated, and the second coupling portion 480 This allows the connection with the battery housing 410 to be released.

[0232] According to the present invention, the battery 40 is separated from the battery housing 410. Therefore, the battery 40 can be securely attached to the charging base and charged.

[0233] Furthermore, since the vacuum cleaner 1 includes the main unit terminal 600, the battery 40 is the battery - By securely attaching the vacuum cleaner 1 to the charging base while it is housed in the housing 410, It can charge a 40-liter battery.

[0234] Figure 23 shows the vacuum cleaner of the present invention with a suction nozzle attached, in the process of cleaning a floor.

[0235] Referring to Figure 23, the suction nozzle 710 is connected to the lower side of the suction section 5 of the vacuum cleaner 1 of the present invention. An extension pipe 700 can be connected.

[0236] In this state, the user moves the suction nozzle 710 while it is placed on the floor. It can be moved to clean.

[0237] In the present invention, when cleaning using the suction nozzle 710, the extension pipe 700 and the floor When the angle is approximately 45 degrees, the angle between the extension pipe 700 and the floor increases or decreases as cleaning is performed. I can.

[0238] In the state shown in Figure 23, the vertical line (VL) passing through the lowest end of the first body 10 As a reference, the intake motor 20 and the battery 40 may be located on opposite sides of each other. That is, the intake motor is located on one side of the vertical line (VL) (for example, in front of the vertical line (VL)). The terminal 20 is located, and the battery 40 is positioned on the other side (for example, behind the vertical line (VL)). And the vertical line (VL) can pass through the handle 30.

[0239] Also, in the state shown in Figure 23, the suction motor 20 and the battery 40 from the floor Their heights are almost identical.

[0240] Therefore, when cleaning the floor while gripping the handle 30, the weight of the vacuum cleaner is The weight is balanced by equipping it to the user's hand, which is gripping the handle, both front and back. In this case, the user can clean with less force using the vacuum cleaner 1, and the user This can prevent strain on the wrist.

[0241] Furthermore, as shown in Figure 23, during the floor cleaning process, the filter mechanism 50 is directed along the vertical line ( The user's hands, which are positioned in front of the vertical line (VL), are positioned behind the vertical line (VL) as they grasp the handle. Therefore, the air discharged from the filter mechanism 50 is directed to the handle 30. Because it flows away from the user, the air discharged from the filter mechanism 50 is directed away from the user. This can prevent it from flowing into your hands.

[0242] Of course, depending on the angle between the extension pipe 700 and the floor, the vertical line (VL) is used as the reference point. It is also possible that only a portion of the intake motor 20 is located on the opposite side of the battery 40. This is the case when cleaning special spaces such as window frames or sofas.

[0243] Figure 24 shows a vacuum cleaner according to another embodiment of the present invention.

[0244] This embodiment is identical to the previous embodiment in other respects, except for the shape of the discharge cover. There are differences in the condition. Therefore, only the characteristic parts of this embodiment will be described below. I've decided to do that.

[0245] Referring to Figure 24, the filter mechanism 811a of this embodiment guides the flow of air discharge. It may include a moving guide 813a.

[0246] Specifically, a plurality of flow guides 813a along the circumferential direction of the filter mechanism 811a They are arranged at a distance from each other. And the space between the multiple flow guides 813a is empty. It serves as the air outlet 813a.

[0247] The plurality of flow guides 813a may be arranged so as to be inclined with respect to a vertical line.

[0248] In this embodiment as well, during the process of cleaning the floor using the suction nozzle, the air outlet 81 This can prevent the air discharged from 2a from flowing towards the user.

[0249] Furthermore, since the filter mechanism 811a is located on the upper side of the vacuum cleaner, the air exhaust The air discharged from outlet 812a can prevent dust from scattering around the vacuum cleaner. ru.

[0250] Figure 25 shows the airflow inside a vacuum cleaner according to the present invention and other embodiments. .
