Embodiment Construction

[0043] figure 1 It is a conceptual diagram showing an example of a vacuum cleaner. figure 2 is viewed from the other direction figure 1 A conceptual diagram of a vacuum cleaner shown. exist figure 1 and figure 2 The shown vacuum cleaner 1 corresponds to an upright.

[0044] The cleaner body 10 together with the dust collector 100 forms the appearance of the vacuum cleaner 1 . The cleaner body 10 is formed to accommodate a part of the dust collector 100 and is formed to be able to be combined with the dust collector 100 . A suction motor (not shown) that generates suction is provided inside the cleaner body 10 . In addition, a driving wheel may be installed on the lower side of the cleaner body 10 .

[0045]The suction part 20 is connected to the lower side of the cleaner body 10 so as to be rotatable relative to the cleaner body 10 , and supports the cleaner body 10 . The suction part 20 is placed on the floor to be cleaned, and a suction port (not shown) for sucking...

Abstract

A dust cleaner includes a primary cyclone part formed by an outer case and an inner case; and a secondary cyclone part including a set of cyclones. The secondary cyclone part includes a casing member mounted on the inner case and configured to form casings of the cyclones arranged around a hollow part; and vortex finders provided inside the casings and including guide vanes extending in a spiral direction and forming a revolving flow at outer circumferential surfaces. The casing member forms inlet flow paths of the cyclones, and each of the inlet flow paths is formed in a direction inclined with respect to a direction toward a center of each of the vortex finders to enable air to flow in a direction eccentric from the center of each of the vortex finders.

Description

technical field [0001] The present invention relates to a dust collecting device for a vacuum cleaner configured to separate and collect dust and fine dust from air by using a multicyclone. Background technique [0002] A vacuum cleaner is a device that sucks in air by suction, separates dust or fine dust contained in the air from the air, and thereby discharges clean air. [0003] Vacuum cleaners can be classified into 1) canister type, 2) upright type, 3) hand-held type, 4) cylinder floor type, and the like. [0004] A canister-type vacuum cleaner is a vacuum cleaner widely used in general households, and is a vacuum cleaner in which a suction nozzle communicates with a vacuum cleaner body through a connecting member. Canisters use only suction to clean and are therefore ideal for cleaning hard floors. [0005] On the contrary, an upright vacuum cleaner is a vacuum cleaner in a form in which a suction nozzle and a cleaner body are integrally formed. Since the upright va...
