[0037] The body 2 may include an intake section 5 through which dust-laden air is sucked in.

[0038] The main body 2 also includes a dust separator for separating the dust sucked into the inside through the suction unit 5. The dust separating unit 10 and the dust box 50 for storing the dust separated from the dust separating unit 10 are provided. It may further include:

[0039] The dust separating unit 10 is, for example, a first cyclone that can separate dust by cyclone flow. The insulating layer 110 may include a thermal expansion module 110.

[0040] The first cyclone portion 110 can be in communication with the suction portion 5 .

[0041] The air and dust sucked through the suction unit 5 are guided to the inner circumferential surface of the first cyclone unit 110. It will flow in a spiral along the line.

[0042] The axis A2 of the cyclone flow of the first cyclone unit 110 extends in the vertical direction.

[0043] The dust separating unit 10 separates dust again from the air discharged from the first cyclone unit 110. In this case, the dust separating unit 10 may further include a second cyclone unit 130. The second cyclone unit 130 is arranged so as to minimize the size of the first cyclone unit 130. The second cyclone unit 130 is located inside the cyclone unit 110. The cyclone body may include a cyclone body. The axis of flow of the suction pump 220 may extend vertically and pass through the suction motor 230 .

[0044] As another example, the dust separating unit may have a single cyclone unit. The axis A2 of the cyclone flow extends in the vertical direction.

[0045] The dust box 50 includes a cylindrical dust collecting body 510 and a dust collecting member 520 below the dust collecting body 510. The housing 500 may include a body cover 520 rotatably coupled to the housing 500 side.

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

[0047] In this embodiment, the first cyclone unit 110 does not exist separately, and the dust collecting body 510 The upper part of the cyclone unit 110 may serve as the first cyclone unit 110.

[0048] At least a portion of the second cyclone unit 130 is located within the dust box 50. This is also fine.

[0049] The dust collecting body 510 stores the dust separated from the second cyclone unit 130. The dust storage guide 504 is disposed to guide the second side. The body cover 520 is connected to the lower side of the clamping part 130 and can contact the upper surface of the body cover 520. do.

[0050] The dust storage guide 504 is arranged to connect the inner space of the dust collection body 510 to the first cyclone. a first dust storage section 502 for storing dust separated from the second cyclone section 110; and a second dust storage section 506 in which dust separated from the dust collector 30 is stored.

[0051] The internal space of the dust storage guide 504 is the second dust storage section 506. The space between the door 504 and the dust collecting body 510 is a first dust storage portion 502 .

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

[0053] The body cover 520 is configured to circulate dust stored in the first dust storage unit 502 in a cyclone flow. The rib 521 is provided to prevent the rib 521 from rotating due to the movement. The body cover 520 extends upward. The body cover 520 is disposed between the first and second In the state where the dust collecting body 502 and the second dust storage portion 506 are covered, the rib 521 510.

[0054] The cyclone flow is generated along the inner circumferential surface of the dust collecting body 510 toward the first dust storage portion 502. Since the dust flows through the dust collecting body 510, the rib 521 is positioned adjacent to the inner peripheral surface of the dust collecting body 510. Then, the cyclone flow is broken by the rib 521 and the dust is stored in the first dust storage part 502. The trapped dust is prevented from rotating.

[0055] The main body 2 may further include a suction force generating unit 20 for generating a suction force. The suction force generating unit 20 includes a motor housing 210 and a The pump may include a suction motor 230 housed within the housing 210 .

[0056] At least a part of the suction motor 230 is located above the dust separating unit 10. Therefore, the suction motor 230 is located above the dust box 50.

[0057] That is, in a state where the longitudinal axis of the suction unit 5 is horizontal, the dust separation unit 10 is The suction motor 230 is arranged to overlap with the suction motor 230 in the vertical direction. A portion of 30 is located inside the first cyclone portion 110 .

[0058] The lower side of the suction motor 230 is connected to the upper side of the second cyclone unit 130. Therefore, the axis A2 of the cyclone flow of the dust separating unit 10 passes through the suction motor 230. The suction motor 230 is rotated from the axis A3 in the longitudinal direction of the suction unit 5. Located high.

[0059] When the suction motor 230 is positioned above the second cyclone unit 130, The air discharged from the aerosol unit 130 can immediately flow to the suction motor 230. The flow path between the dust separating unit 10 and the suction motor 230 is minimized.

[0060] The suction motor 230 may include a rotating impeller 232. The propeller 232 is connected to a shaft 233. The shaft 233 extends in the vertical direction. At least a part of the dust separating unit 10 is disposed inside the dust separating unit 10. When the dust box 50 and the suction motor 230 are arranged vertically, the vacuum cleaner 1 The height of the impeller 232 can be reduced. The extension line of the motor axis passes through the dust separating unit 10 and the dust box 50. can be done.

[0061] At this time, the rotation axis A1 of the impeller 232 and the first cyclone portion 1 of the dust separating portion 10 The axis A2 of the cyclone flow emanating from 10 is collinear.

[0062] According to the present invention, the air discharged from the dust separating section, i.e., the second cyclone section 130 The air discharged upward from the intake duct 230 has fewer paths to flow toward the intake motor 230, and the air flow direction is This has the advantage of reducing the amount of air that is blown into the cavity and reducing air flow losses.

[0063] When the air flow loss decreases, the suction force increases, providing power to the suction motor 230. This increases the usage time of the battery by 40.

[0064] Between the suction motor 230 and the second cyclone unit 130, 0 is where the PCB 250 for control is located.

[0065] The vacuum cleaner 1 includes a handle 30 for a user to hold, and a power supply for the suction motor 230. It may further include a battery 40 for providing a power source.

[0066] The handle 30 is located behind the suction motor 20. The axis of 230 is located between the intake part 5 and the handle 30 .

[0067] When the direction is defined as the direction of the suction motor 230 in the vacuum cleaner 1, 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 is located below the handle 30. 0 is located behind the dust box 50.

[0069] Therefore, the suction motor 230 and the battery 40 are arranged so as not to overlap each other in the vertical direction. The electrodes are arranged so that the heights of the electrodes are different.

[0070] According to the present invention, the suction motor 230, which is heavy based on the handle 30, is located in front of the handle 30, and the heavy battery 40 is located under the handle 30. The weight of the vacuum cleaner 1 is evenly distributed throughout the vacuum cleaner 1. When holding the cleaner 30 for cleaning, the user's wrist is prevented from being strained. The heavy components are distributed at the front and rear of the vacuum cleaner 1 and are arranged at different heights. This prevents the vacuum cleaner 1 from being tilted to one side where the center of gravity is located.

[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 outer appearance of the upper surface of the vacuum cleaner 1.

[0072] Therefore, in the process of gripping the handle 30 and using the vacuum cleaner 1, a part of the vacuum cleaner 1 may be Contact with the arm is prevented.

[0073] The handle 30 includes a first extension 310 that extends in the vertical direction and can be held by a user; A second extension part 310 extends from the upper side of the first extension part 310 toward the suction motor 230. The second extension portion 320 may include a first extension portion 320. The second extension portion 320 may include a second extension portion 320 that is at least partially extended in a horizontal direction. can be.

[0074] The first extension 310 is provided with a hand when the user holds the first extension 310. 1. A movement limiter for preventing the extension portion 310 from moving in the longitudinal direction (vertical direction in FIG. 2). The movement limiting portion 312 is provided to move the first extension portion 310 to the suction portion 312. It is extended towards 5.

[0075] The movement limiting portion 312 is spaced apart from the second extension portion 320. When the first extension portion 310 is gripped, some of the fingers are positioned above the movement limiting portion 312, and the remaining The finger is positioned below the movement limiting portion 312 .

[0076] As an example, the movement limiting portion 312 is located between the index finger and the middle finger.

[0077] In the present invention, the longitudinal axis A3 of the suction portion 5 passes through the first extension portion 310. In this case, the movement limiting portion 312 is positioned higher than the axis A 3 of the suction portion 5 in the longitudinal direction.

[0078] With this arrangement, the user can hold the first extension portion 310 and press the inhaler. The longitudinal axis A3 of the portion 5 can pass through the wrist of the user.

[0079] When the longitudinal axis A3 of the inhalation portion 5 passes through the wrist of the user, the user's arm is extended. In this state, the longitudinal axis A3 of the inhalation portion 5 is substantially aligned with the extension of the user's arm. Therefore, in this state, when the user holds the handle 30 and pushes the vacuum cleaner 1, This has the advantage that the user force required when pulling is minimised.

[0080] The handle 310 may include an inclined surface 315 on which an operating portion 316 is located. The vacuum cleaner can be turned on and off by inputting commands via the operation unit 316. The inclined surface 315 is arranged to face the user. The operation part 316 is located on the rear surface of the second extension part 314. is located on the opposite side of the movement limiting portion 312. 316 is located higher than the movement limiting portion 312. The operating portion 316 can be easily operated with the thumb while holding the handheld terminal 10.

[0081] In addition, since the operating portion 316 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 316 may be unintentionally operated. This prevents the data from being leaked.

[0082] The second extension 314 is provided with a display 318 for displaying an operating state. For example, the display unit 318 is located on the upper surface of the second extension portion 314. In the course of cleaning, the display unit 318 located on the upper surface of the second extension portion 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 may be arranged in a longitudinal direction of the second extension part 314 at intervals.

[0084] Meanwhile, a battery housing 410 is provided under the handle 30. The battery 40 is accommodated inside the battery housing 410. The battery housing 410 is located below the portion 310 .

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

[0086] The battery housing 410 is provided with a heat dissipating device for discharging heat generated from the battery 40 to the outside. A heat dissipation hole 412 is formed to allow the heat to escape.

[0087] The rear surface of the battery housing 410 and the rear surface of the first extension portion 310 form a continuous surface. Therefore, the battery housing 410 and the first extension portion 31 0 can have a sense of unity.

The axis A2 of the chronotropic flow can pass through the exhaust cover 211. 212 is disposed so as to surround the rotation axis A1 of the impeller 232. At this time, the air discharged through the air outlet 212 is aligned with the rotation axis A of the impeller 232. The discharge cover 210 has a flow guide 21 so that the liquid is discharged in an inclined direction based on the reference angle 1. The direction in which air is drawn in through the suction unit 5 is the same as the direction in which the air is drawn in through the air outlet 2. 12 intersects with the discharge direction through which air is discharged.

[0089] The air discharged from the air outlet 212 is prevented from flowing toward the user. 3, at least a distance between the rotation axis A1 of the impeller 232 and the handle 30 is However, some areas may not have an air outlet. When the air flow is divided into front and rear portions around the axis A2 of the air flow, at least a portion of the air exhaust port 212 is , located in front of the axis A2 of the cyclone flow.
