Abstract: A pump (8) is disclosed. The pump (8) includes a partition wall (84) configured to divide the interior of a body into two spaces, a first chamber (C1) located under the partition wall (84), the first chamber (C1) having an introduction portion (841), through which water is introduced, a second chamber (C2) located above the partition wall (84), the second chamber (C2) having a discharge portion (849), through which water is discharged, a communication hole (86) formed through the partition wall (84) to allow the first chamber (C1) and the second chamber (C2) to communicate with each other therethrough, an impeller (85) provided in the second chamber (C2) to move water to the discharge portion (849), a housing configured to define the bottom surface of the first chamber (C1), the housing being made of a conductor, a heater (H) configured to heat the housing (81), and a steam discharge (843) port formed through the first chamber (C1) to allow steam to be discharged therethrough.

Abstract: The present invention provides a dust collecting apparatus for a vacuum cleaner, comprising: a first cyclone installed in a first case and configured to separate dust from air introduced thereinto together with foreign substances and to discharge the separated dust to a first dust storage unit; a second cyclone mounted above the first cyclone and configured to separate fine dust from the air from which the dust is separated by the first cyclone and to discharge the separated fine dust to a second dust storage unit; a compression device configured such that at least a part thereof performs normal rotation in one direction and reverse rotation in the direction opposite to that of the normal rotation along the outer peripheral surface of a second case having the second dust storage unit therein to compress the dust stored in the first dust storage unit; a screw rotatably installed above the compression device and having a guide vane spirally extending along the outer periphery thereof to guide the collection of dust into the first dust storage unit; a driving unit that transmits a driving force to the compression device to selectively enable the normal rotation and the reverse rotation of the compression device; and a gear unit installed between the compression device and the screw to enable the screw to perform normal rotation while the compression device performs the normal rotation and the reverse rotation.

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.

Abstract: A dust collector includes a primary cyclone unit to separate dust from air introduced from outside dust collector and a secondary cyclone unit includes axial cyclones which separate fine dust from air introduced in an axial direction. The secondary cyclone unit includes a first group of axial cyclones disposed along a circumference of a first circle so as to contact an inner circumferential surface of an inner case, and formed to be partially spaced apart from the inner circumferential surface of the inner case to form first passages therebetween; and a second group of axial cyclones disposed to contact each other along a circumference of a second circle concentric with the first circle and smaller than the first circle, and formed to contact some of the first group of axial cyclones and to be spaced apart from others of the first group axial cyclones to form second passages therebetween.
