Definitions

  • the present invention relates to a vacuum cleaner, and more particularly, to a vacuum cleaner having a pre-filter and a HEPA filter.
  • a vacuum cleaner is a household appliance that sucks in small garbage or dust in a manner that uses electricity to suck air and fills the dust bin in the product, and is generally referred to as a vacuum cleaner.
  • Such a vacuum cleaner may be divided into a manual cleaner in which a user directly moves the cleaner and performs cleaning, and an automatic cleaner in which the user performs cleaning while driving by themselves.
  • Manual vacuum cleaners may be classified into canister-type cleaners, upright cleaners, handy-type cleaners, stick-type cleaners, and the like, depending on the type of cleaner.
  • canister-type vacuum cleaners were used a lot in household cleaners, but recently, hand-held vacuum cleaners and stick cleaners, which are convenient to use by providing a dust container and a cleaner body, are increasingly used.
  • the canisty type vacuum cleaner is connected to the main body and the suction port by a rubber hose or pipe, and in some cases, it can be used by inserting a brush into the suction port.
  • the Hand Vacuum Cleaner maximizes portability, and since it is light in weight but short in length, there may be restrictions on the cleaning area while sitting. Therefore, it is used to clean localized places such as on a desk or sofa, or in a car.
  • the stick vacuum cleaner can be used while standing, so you can clean without bending your back. Therefore, it is advantageous for cleaning while moving a large area. If a hand-held vacuum cleaner cleans a narrow space, the stick-type vacuum cleaner can clean a wider space than that, and can clean a high place that cannot be reached by hand. Recently, a stick cleaner is provided in a module type, and the cleaner type is actively changed and used for various objects.
  • the prior art includes a suction conduit, an airflow generator for creating an airflow along the suction conduit, a separation device in communication with the suction conduit to separate dirt and dust from the airflow, and a handle enabling a user to operate the portable cleaning appliance do.

  • the air is discharged from the cyclone to the upper part, but in the pre-filter, the flow direction of the air is bent because it has to flow backward.
  • the air flows backward in the motor, but in the HEPA filter, the flow direction is bent once more because it has to flow upward.
  • the air flowing inside the cleaner is bent at least twice or more, and thus a pressure loss occurs, resulting in a problem in which the performance of the cleaner is deteriorated.
  • the longitudinal axis of the handle is arranged almost parallel to the insertion axis of the pre-filter, the user wants to remove the pre-filter by pulling the pre-filter, even if the angle at which the pre-filter is detached slightly deviates from the insertion axis of the pre-filter.
