Definitions

  • the present invention relates to a vacuum cleaner, and more particularly, to a parking device for a nozzle of a vacuum cleaner for use on a vacuum cleaner having more than one base.
  • the inventive parking device allows a nozzle portion including an extension tube to be hooked onto the floor portion of the vacuum cleaner, thereby facilitating storage and transportation of the vacuum cleaner.
  • a vacuum cleaner is used to clean a room or other spaces by sucking air containing foreign objects and filtering the foreign object using vacuum pressure generated therein.
  • a dust collection unit with a filtering unit is provided in the vacuum cleaner.
  • the filtering unit is classified into a porous filter formed of porous material and a cyclone type filter.
  • the porous filter formed of porous material is designed to filter the foreign objects contained in air while the air passes through the filter.
  • the cyclone type filter is designed to filter the foreign objects using cyclone airflow.
  • a user cleans the filter to remove the foreign objects clogged in the filter.
  • the porous filter cannot be reused. Since the cyclone type filter is designed to remove the foreign objects from the air by a rotational air current generated by cyclone airflow, the clogging of the foreign objects in the filter is not incurred. Due to this reason, in recent years, cyclone type filter has been widely used.
  • the nozzle portion When a vacuum cleaner is stored or moved, the nozzle portion is parked on the main body of the vacuum cleaner, allowing easy storage and transport of the vacuum cleaner.
  • the parking position is generally located on the bottom or the rear of the main body of the vacuum cleaner.
  • a parking portion located at the front of a main body of the vacuum cleaner tends to be structurally weak and therefore easily damaged, preventing its performance of its given task.
  • US-A-5125127 discloses a holding device for a suction tube nozzle unit on an electrical vacuum cleaner.
  • the vacuum cleaner has a base defining a lower floor portion of a main body of the vacuum cleaner.
  • an opening into which a hook portion attached to the suction tube nozzle unit can be engaged to mount the suction tube nozzle unit to the base.
  • a spring arm Inside the base is provided a spring arm that, simultaneously with the engaging of the hook portion into the opening, is slided and thereby pivots a retaining clip outward from the base serving to hold the suction tube of the suction tube nozzle unit at a further position.
  • US-A-4545089 discloses a type of vacuum cleaner which always stands on a suction assembly.
  • the vacuum cleaner housing has a pocket for nesting an accessory appliance like a separate mobile handheld vacuum cleaner.
  • a latch mechanism maintains the accessory appliance within the pocket and is releasable to permit removal of the accessory appliance.
  • the latch mechanism is supported on a separate intermediate wall and only a latch catch thereof protrudes through an opening in the housing outer wall at the pocket and engages a recess of the accessory appliance.
  • the present invention is directed to a vacuum cleaner with a suction assembly parking device that substantially obviates one or more problems due to limitations and disadvantages of the related art.
  • An object of the present invention is to provide a vacuum cleaner and a strong parking device for a nozzle of a vacuum cleaner located on the underside of the vacuum cleaner.
  • An aspect of the present invention is to provide a vacuum cleaner and a parking device for a nozzle of a vacuum cleaner capable of firmly reinforcing a multi-level base of a vacuum cleaner (as is the case with vacuum cleaners employing multi cyclone dust collection units).
  • the parking device for a nozzle of a vacuum cleaner according to the present invention provides increased structural strength strength and durability of the vacuum cleaner.

  • FIG. 1 shows a vacuum cleaner to which a dust collection unit according to the present invention can be applied.
  • a vacuum cleaner includes a main body 100 and a suction assembly connected to a suction portion through which outer air is sucked into the main body 100. Disposed in the main body 100 are a suction fan and a dust collection unit. Therefore, the sucked air is exhausted out of the main body 100 after foreign objects contained in the sucked air are filtered.
  • the suction assembly is provided to suck the air containing the foreign objects when sucking force is generated in the main body 100. That is, the suction assembly includes a sucking nozzle body 1 for sucking the air containing the foreign objects using a powerful airflow, an expandable pipe 2 extending from the sucking nozzle body 1 and expandable and contractible by a user, an operation handle 3 provided on a distal end of the expandable pipe 2, a manipulation unit 4 provided on a front portion of the operation handle 3, a flexible tube 5 extending from the operation handle 3, a connector 6 connecting a distal end of the flexible tube 5 to the main body 100, a pipe rest 7 on which the expandable pipe 2 can be supported and suspended when the vacuum cleaner is not used.
  • the connector 6 functions as a connection terminal transmitting a manipulation signal inputted by the user through the manipulation unit 4 to the main body 100 as well as a passage through which the sucked air is introduced into the main body 100. That is, a plurality of electric connection terminals are provided on a proximal end of the connector 6. However, the electric connection terminals are required only when the manipulation unit 4 is provided on the suction assembly. That is, the electric connection terminals are not provided on the connector 6. In this case, the connector 6 may simply function as an air introducing passage.
  • the air introduced into the main body 100 through the suction assembly is exhausted out of the main body 100 after the foreign objects contained in the introduced air are filtered.
  • the main body 100 of the vacuum cleaner will be described in more detail hereinafter with reference to FIGs. 1 and 2 .
  • FIG. 2 shows the main body of the vacuum cleaner.
  • the main body 100 includes a first base 110 defining a lower portion of the main body 100, a second base 150 disposed on the first base 110, a cover 200 disposed on the second base 150, wheels 111 provided on both rear-side portions of the cover 200 to make it easy to move the main body 100, and a front support 170 for supportably fixing the cover 200 and the first and second bases 110 and 150.
  • the connector 6 is connected to the front support 170 to allow the outer air to be introduced into the main body 100.
  • the support 170 is designed to support the cover 200 and the first and second bases 110 and 150, thereby securely supporting the front portion of the main body 100.
  • the second base 150 is provided right above the first base 110 to improve the ornament of the main body and enhance the rigidity of the lower portion of the main body.
  • An exhaust cover 301 provided with a plurality of exhaust holes 302 is provided on a rear portion of the cover 200 to exhaust clean air.
  • a carrying handle 201 is pivotally provided on a top surface of the cover 200. When a user intends to carry the main body 100, the carrying handle 201 is pivoted to a vertical position and used to conveniently carry the main body 100.
  • a dust collection unit 400 is disposed in the main body behind the front support 170 and a cyclone member is received in the dust collection unit to generate cyclone airflows and filter the foreign object contained in the outside air.
  • the dust collection unit 400 is vertically installed in and separated from a receiving chamber 151 defined in the main body 100. That is, the dust collection unit 400 may be installed in the receiving chamber 151 by being pushed downward and separated from the receiving chamber 151 by being pulled upward.
  • the front support 170 is provided with a first air intake hole 171 and the dust collection unit 400 is provided with a second air intake hole 401 corresponding to the first air intake hole 171.
  • the dust collection unit 400 is further provided with an exhaust hole (not shown) opposite to the second air intake hole 401.
  • the exhaust hole is aligned with a third air intake hole 172 formed toward the motor so that the air cleaned by passing through the collection unit 400 is exhausted toward the motor side.
  • the third air intake hole 172 is formed in a rectangular shape lengthwise in a horizontal direction so as to reduce the size of the main body 100 and allow the air to effectively flow.
  • FIG. 4 shows the main body of the vacuum cleaner.
  • the second base 150 is disposed on a rear-top portion of the first base 110.
  • a motor housing 300 is disposed on a rear portion of the first base 110.
  • the cover 200 is sequentially coupled to the first and second bases 110 and 150 to define the main body 100.
  • the cover 200 is coupled to the first and second bases 110 and 150 in a state where the front support 170 is coupled to the cover 200.
  • a flowing direction of the air introduced into the motor housing 300 through the third air intake hole 172 is changed by 90° in a vertical direction and is then changed in a horizontal direction so that the air can be exhausted rearward.
  • the first and second base 110 and 150 are stacked and aligned.
  • the base 110 and 150 consists of two components for the sake of structural strength; and the separate manufacturing of the two components allows the outer surface of one of the components to be manufactured having a smooth surface without grooves. Additionally, shocks inflicted on the main body of the vacuum cleaner via the base are absorbed by the base. Such shock-resistant bases are especially needed by multi-cyclone dust collection units employing multiple ducts for separating foreign objects via cyclone airflow.
  • a nozzle parking portion is formed on the second base 150.
  • a detailed explanation of the structure of the nozzle parking portion will hereinafter be given.
  • FIG. 5 is a frontal perspective view of a base of a vacuum cleaner according to an embodiment of the present invention
