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

[0035] Figure 4 is a longitudinal cross-sectional view of a vacuum cleaner according to one embodiment of the present invention, and Figure 5 is related to one embodiment of the present invention. This is a cross-sectional view of a vacuum cleaner.

[0036] Referring to Figures 1 to 5, the vacuum cleaner 1 according to one embodiment of the present invention may include a main body 2. Cut.

[0037] The main body 2 may include an intake section 5 into which dust-containing air is drawn in.

[0038] Furthermore, the main body 2 is equipped with a dust filter to separate dust that has been sucked into the interior via the suction section 5. A separation unit 10 and a dust box 50 for storing the dust separated from the dust separation unit 10 are provided. It can also include more.

[0039] The dust separation unit 10 includes, for example, a first cyclone capable of separating dust by cyclone flow. It can include a ron section 110.

[0040] The first cyclone section 110 can communicate with the intake section 5.

[0041] 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 path.

[0042] The axis A2 of the cyclone flow in the first cyclone section 110 is extended in the vertical direction.

[0043] The dust separation unit 10 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 of the first cyclone section, the second cyclone section 130 is configured to minimize the size of the first cyclone section It is located inside 110. The second cyclone section 130 consists of multiple cyclones arranged in parallel. It may include a cyclone body, and the cyclones generated from each of the cyclone bodies The shaft of the ron flow is extended vertically and can pass through the suction motor 230.

[0044] As another example, the dust separation unit may have a single cyclone unit, and in this case as well, The axis A2 of the icron flow is extended in the vertical direction.

[0045] The dust box 50 comprises a cylindrical dust collection body 510 and below the dust collection body 510 It may include a body cover 520 that is rotatably coupled to the side.

[0046] The longitudinal axis A3 of the intake portion 5 is such that the longitudinal axis A3 of the intake portion 5 is horizontal. In this state, it is located above the body cover 520.

[0047] In this embodiment, the first cyclone section 110 is not present separately, and the dust collection body 510 The upper part may also function as the first cyclone section 110.

[0048] At least a portion of the second cyclone section 130 is located inside the dust box 50. That's fine.

[0049] The dust collection body 510 stores the dust separated from the second cyclone unit 130. A dust storage guide 504 is positioned to guide the dust. It is coupled to the lower side of the chron section 130 and can contact the upper surface of the body cover 520. ru.

[0050] The dust storage guide 504 provides space inside the dust collection body 510 for the first cyclone The first dust storage section 502 stores the dust separated from section 110, and the second cyclone section 1 The unit can be partitioned into a second dust storage unit 506 where dust separated from unit 30 is stored.

[0051] The internal space of the dust storage guide 504 is the second dust storage section 506, and the dust storage guide The space between the do 504 and the dust collection body 510 is the first dust storage section 502.

[0052] The body cover 520 combines the first dust storage section 502 and the second dust storage section 506. It can be opened and closed.

[0053] The body cover 520 is designed so that dust stored in the first dust storage section 502 flows in a cyclone. A rib 521 is provided to prevent rotation due to motion. The rib 521 is The body cover 520 extends upward from the first With the second dust storage sections 502 and 506 covered, the rib 521 is the dust collection body It is positioned adjacent to the inner surface of 510.

[0054] The cyclone flow flows along the inner circumferential surface of the dust collection body 510 towards the first dust storage section 502. As it flows, the rib 521 is positioned adjacent to the inner circumferential surface of the dust collection body 510. As a result, the cyclone flow is disrupted by the rib 521 and stored in the first dust storage section 502. This prevents the collected dust from rotating.

[0055] The main body 2 further includes a suction force generation unit 20 for generating suction force. Yes, it is possible. The suction force generating unit 20 comprises a motor housing 210 and the motor housing The suction motor 230 can be housed inside the 210.

[0056] Furthermore, at least a portion of the suction motor 230 is located above the dust separation unit 10. Therefore, the suction motor 230 is located above the dust box 50.

[0057] That is, with the longitudinal axis of the suction section 5 in a horizontal position, the dust separation section 10 is as follows: It is positioned so as to overlap the intake motor 230 in the vertical direction. A portion of 30 is located inside the first cyclone section 110.

[0058] The lower side of the intake motor 230 is connected to the upper side of the second cyclone section 130. Therefore, the cyclone flow axis A2 of the dust separation unit 10 passes through the suction motor 230. This is possible. And the suction motor 230 is located from the longitudinal axis A3 of the suction section 5. It is located at a high position.

[0059] When the intake motor 230 is located above the second cyclone section 130, the second s The air discharged from the icon section 130 can immediately flow towards the suction motor 230, The flow path between the dust separation unit 10 and the suction motor 230 is minimized.

[0060] The intake motor 230 may include a rotating impeller 232. The propeller 232 is connected to the shaft 233. The shaft 233 extends in the vertical direction. It is arranged so as to be positioned, and at least a portion of it is located inside the dust separation section 10. In this case, When the dust box 50 and the suction motor 230 are arranged vertically, the vacuum cleaner 1 There is an advantage in that the height can be reduced. The rotation axis A1 of the impeller 232 (or intake motor The extension of the axis of the data passes through the dust separation section 10 and the dust box 50. It is possible.

[0061] At this time, the rotation shaft A1 of the impeller 232 and the first cyclone section 1 of the dust separation section 10 The axis A2 of the cyclone flow originating from point 10 lies on the same line.

[0062] According to the present invention, the air discharged from the dust separation unit, that is, the second cyclone unit 130 The path through which the air discharged upward flows towards the intake motor 230 is reduced, and the direction of the air changes. This has the advantage of reducing condensation and decreasing airflow loss.

[0063] When airflow loss decreases, the suction force increases, supplying power to the suction motor 230. This increases the battery usage time by 40.

[0064] Between the intake motor 230 and the second cyclone section 130, the intake motor 23 PCB250 is located at 0 for control.

[0065] The vacuum cleaner 1 includes a handle 30 for the user to grip and an electric motor 230. It may further include a battery 40 for supplying power.

[0066] The handle 30 is located behind the intake motor 20. Therefore, the intake motor The shaft of 230 is located between the suction section 5 and the handle 30.

[0067] When defined in terms of direction, in the vacuum cleaner 1, with respect to the suction motor 230, 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 is located below the handle 30. Point 0 is located behind the dustbin 50.

[0069] Therefore, the intake motor 230 and the battery 40 are arranged so that they do not overlap in the vertical direction. They are arranged, and their heights are also different.

[0070] According to the present invention, the heavier suction motor 230 is compared to the handle 30. The heavy battery 40 is located in front of the handle 30 and below the handle 30. Because it is located on the side, the weight is evenly distributed throughout the vacuum cleaner 1. When using the L30 to clean, strain on the user's wrist is prevented. The heavy components are distributed and positioned at the front and rear of the vacuum cleaner 1, and at different heights from each other. Because it is positioned in this way, the center of gravity of the vacuum cleaner 1 is prevented from shifting to one side.

[0071] The battery 40 is located below the handle 30, and the suction motor 230 is Since it 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 a part of the upper surface appearance of the vacuum cleaner 1.

[0072] Therefore, in the process of gripping and using the handle 30, some components of the vacuum cleaner 1 are used by the user. Contact with the arm is prevented.

[0073] The handle 30 extends vertically and includes a first extension 310 that can be gripped by the user, A second extension 3 extends above the first extension 310 toward the intake motor 230. It may include 20. The second extension 320 is at least partially extended horizontally. It can be done.

Movement restriction to prevent movement of extension 310 in the longitudinal direction (vertical direction in Figure 2) A section 312 is provided. The movement limiting section 312 extends from the first extension section 310 to the suction section It extends towards 5.

[0075] The movement limiting portion 312 is positioned at a distance from the second extension portion 320. With the first extension 310 being grasped, some fingers are positioned above the movement-restricting portion 312, and the rest The finger is located below the movement-restricting portion 312.

[0076] For example, the movement-restricting portion 312 is located between the index finger and the middle finger.

[0077] In this invention, the longitudinal axis A3 of the intake portion 5 passes through the first extension portion 310. Furthermore, the movement limiting portion 312 is positioned higher than the longitudinal axis A3 of the suction portion 5.

[0078] With this arrangement, the user can grasp the first extension 310 and then perform the suction. The longitudinal axis A3 of part 5 can pass through the user's wrist.

[0079] When the longitudinal axis A3 of the suction part 5 passes through the user's wrist, the user's arm is extended. In this state, the longitudinal axis A3 of the suction section 5 is substantially aligned with the extension direction of the user's arm. Therefore, in this state, the user grips the handle 30 and pushes the vacuum cleaner 1. This has the advantage of minimizing the force required from the user when pulling.

[0080] The handle 310 may include an inclined surface 315 on which the operating section 316 is located. On and off commands for the vacuum cleaner can be input via the operation unit 316. The inclined surface 315 is positioned to face the user. For example, the inclined surface 315 is: It is located on the rear surface of the second extension 314. The operating section 316 is located relative to the handle 30. The operating part is located on the opposite side of the movement limiting part 312. 316 is positioned higher than the movement limiting portion 312. Therefore, the user can move the first extension portion 3 The operating unit 316 can be easily operated with the thumb while holding the 10.

[0081] Furthermore, since the operating section 316 is located at a position separate from the first extension 310, When cleaning is performed while gripping the first extension 310, the operating part 316 may be operated unintentionally. This prevents it from happening.

[0082] The second extension 314 is provided with a display unit 318 for displaying the operating status. The display unit 318 is located, for example, on the upper surface of the second extension 314. Therefore, the user During the cleaning process, the display unit 318 located on the upper surface of the second extension 314 can be easily checked. It is possible.

[0083] The display unit 318 may include, but is not limited to, a number of light-emitting units. The light-emitting parts can be arranged spaced apart in the longitudinal direction of the second extension 314.

Section 211 houses a HEPA filter 246 for filtering air. The axis A2 of the chlorofluid can pass through the discharge cover 211. As an example, 212 is positioned to surround the rotation axis A1 of the impeller 232. At that time, the air discharged through the air outlet 212 is directed towards the rotation axis A of the impeller 232. The discharge cover 210 has a flow guide 21 so that the discharge is directed in a direction that is inclined with respect to 1. 3 is provided. The intake direction in which air is drawn in through the intake section 5 is the air outlet 2 The direction of exhaust intersects with the direction of air discharge through 12.

[0089] To prevent the air discharged from the air outlet 212 from flowing towards the user. Using Figure 3 as a reference, the minimum distance between the rotation axis A1 of the impeller 232 and the handle 30 In some areas, an air outlet may not be formed. That is, the vacuum cleaner is the cyclo When the airflow axis A2 is divided into front and back sections, at least a part of the air outlet 212 is It is located in front of the axis A2 of the cyclone flow.

[0141] Figure 15 is a diagram showing the vacuum cleaner of the present invention with a suction nozzle attached to clean the floor.

[0142] Referring to Figure 15, the suction nozzle 710 is connected to the lower side of the suction section 5 of the vacuum cleaner 1 of the present invention. The extension pipe 700 is connected.

[0143] In this state, the user places the suction nozzle 710 on the floor and then moves the suction nozzle 710 It can be used for cleaning while moving around.

[0144] In this invention, when cleaning using the suction nozzle 710, the extension pipe 700 and the floor With an angle of approximately 45 degrees, cleaning is performed while the angle between the extension pipe 700 and the floor increases or decreases. .

[0145] In the state shown in Figure 15, the vertical line VL that penetrates the lowest end of the dust box 50 is used as a reference. Furthermore, the intake motor 230 and the battery 40 are located on opposite sides of each other. That is, the vertical The suction motor 230 is located on one side of the straight line VL (for example, in front of the vertical line VL), and on the other side (for example) The battery 40 is positioned behind the vertical line VL. The vertical line VL is It can pass over handle 30.

[0146] Furthermore, in the state shown in Figure 15, the suction motor 230 and the battery 40 from the floor The heights are almost identical.

[0147] Therefore, when cleaning the floor while gripping the handle 30, the weight of the vacuum cleaner is the hand The weight balance is achieved by using the user's hand, which is gripping the object, as a reference point.

[0150] Figure 16 is a drawing showing a vacuum cleaner according to another embodiment of the present invention.

[0151] This embodiment is identical to the previous embodiment in other respects, but the shape of the discharge cover differs. There is a difference. Therefore, in the following, we will only explain the characteristic parts of this embodiment. ru.

[0152] Referring to Figure 16, the discharge cover 211a of this embodiment is a fluid gas that guides the discharge of air. Id 213a is provided.

[0153] Specifically, a number of flow guides 213a are separated along the circumferential direction of the discharge cover 211a. They are arranged at a distance from each other. The spaced-out area between the numerous flow guides 213a is used for air exhaust. It serves the function of exit 212a.

[0154] The aforementioned numerous flow guides 213a are arranged to be inclined with respect to a vertical line.

[0155] In this embodiment as well, during the process of cleaning the floor using the suction nozzle, the air outlet 212a This prevents the air discharged from the device from flowing towards the user.

[0156] Furthermore, since the discharge cover 211a is positioned on the upper side of the vacuum cleaner, the air outlet The air discharged from 212a prevents dust from scattering around the vacuum cleaner.

[0157] Figure 17 is a diagram showing the airflow inside a vacuum cleaner according to yet another embodiment of the present invention. ru.

[0158] This embodiment is identical to the previous embodiment in other respects, but the structure of the dust flow guide is different. There are differences. Therefore, in the following, we will only explain the characteristic parts of this embodiment. do.

[0159] Referring to Figure 17, at least a portion of the dust flow guide 504 in this embodiment is from top to bottom It is formed so that the diameter decreases towards the side. For example, on the dust flow guide 504 A portion of the side is formed so that its diameter decreases as it goes downwards.

[0160] Furthermore, the dust flow guide 504 extends downward from the upper end of the dust flow guide 504. It may include a splash-proof rib 504a. The splash-proof rib 504a is, for example, It is formed in a cylindrical shape and can surround the upper part of the dust flow guide 504.

[0161] At this time, the diameter of the upper part of the dust flow guide 504 decreases as it moves downwards, A space is formed between the outer surface of the upper part of the dust flow guide 504 and the dust scattering prevention rib 504a. ru.

[0162] As described in the previous embodiment, the cyclone flow follows the inner circumferential surface of the dust collection body 510. It can descend while flowing. In the process of the cyclone flow descending, the cyclone When the ron flow comes into contact with the rib 521 of the body cover 520, the rotational flow is directed towards the rib 52 1 changes to an upward flow. If an upward flow exists within the first dust storage section 502 In that case, the dust stored in the first dust storage unit 502 will scatter towards the second cyclone unit 130. There is a problem of backflow.

[0163] In the present invention, the upward flow within the first dust storage section 502 is due to the dust-preventing rib 504a The dust-preventing rib 504a is again in the space between the upper part of the dust flow guide 504 and the dust flow guide 504. As the flow changes to a downward flow, the dust stored in the first dust storage unit 502 is prevented from scattering. This prevents dust from flowing back into the second cyclone section 130.

[0164] On the other hand, the dust prevention rib 504a extends downward from the upper end of the dust flow guide 504. Therefore, the dust separated from the first cyclone section 110 along with the cyclone flow is The dust-preventing rib 504a allows the dust to move smoothly to the first dust storage section 502. ru.

[0165] Figure 18 is a diagram showing the airflow inside a vacuum cleaner according to yet another embodiment of the present invention. ru.

[0166] This embodiment is identical to the previous embodiment in other respects, except for the impeller arrangement of the intake motor. There are differences in placement. Therefore, in the following, we will only explain the characteristic parts of this embodiment. do.

[0167] Referring to Figures 8 and 18, the suction motor 230a of this embodiment is connected to the impeller 232a It is positioned inside the motor housing so that it is located on the lower side. That is, the suction motor 230 The air inlet of a is positioned to face the second cyclone section 130.

[0168] According to this embodiment, the air discharged from the second cyclone section 130 immediately rises forward. The air flows towards the impeller 232a, and the air that has passed through the impeller 232a does not rise again. It is then discharged from the vacuum cleaner.

[0169] With this arrangement of the intake motor, the air discharged from the second cyclone section 130 Since the airflow path is minimized until the air is discharged outside the vacuum cleaner, flow loss is minimized. There are advantages to this transformation.
