Description

  The present invention relates to a vacuum cleaner having a dust collection case that can be removed from a vacuum cleaner body.

  There are two types of conventional vacuum cleaners that have a dust collection case, one that collects cyclones and the other that collects dust using a paper pack. For example, a cyclone dust collection type vacuum cleaner is provided with a separation chamber for centrifugal separation of dust in the dust collection case, and the dust is separated from the cleaning air flow by centrifugal force by rotating the cleaning air flow containing dust in the separation chamber. (For example, refer to Patent Document 1).

Japanese Patent No. 3365410 (paragraphs 0022 to 0048, FIGS. 2 to 6)

  On the other hand, in a conventional paper pack type vacuum cleaner having a dust collection case, a cleaning airflow is passed through the paper pack set in the dust collection case, and dust is collected by the filtering action of the paper pack. (For example, refer to Patent Document 2).

JP 2002-17628 (paragraphs 0015 to 0026, FIGS. 1 to 6)

  Conventional vacuum cleaners that perform cyclone dust collection can collect dust by the rotational force of the airflow, so consumable parts such as paper packs that must be purchased for dust collection even when using a vacuum cleaner However, since the running cost can be reduced and the user can have a good feeling, the members constituting the dust collection case such as the separation chamber for collecting dust and the dust storage chamber for storing the separated dust, The maintenance of each filter was particularly troublesome.

  On the other hand, conventional vacuum cleaners that collect dust in paper packs can dispose of dust with each paper pack when the paper pack that contains dust is full. When dust accumulates, the suction force decreases, or the cleaning airflow passes through the dust contained in the paper pack and exhausts it, so that a strange odor may be generated depending on the dust contained in the paper pack. Fear was also conceivable. In addition, the replacement of the paper pack is troublesome, and there is a problem that the replacement cost of the paper pack is generated.

  In this way, cyclone dust collection and paper pack dust collection have their merits and demerits, and depending on the application and purpose, for example, when you want to simplify maintenance, use paper pack dust collection, when you do not want to replace the paper pack, If you want to keep running costs down, you can consider using cyclone dust collection. However, in order to do so, two vacuum cleaners, a cyclone dust collecting vacuum cleaner and a paper pack dust collecting vacuum cleaner, are required. Normally, in general households, you do not purchase two vacuum cleaners, but you can choose which type to purchase at the time of purchase. It was difficult to choose.

  The present invention has been made to solve the above-described problems, and a user selects a cyclone dust collection method and a paper pack dust collection method according to the application and purpose with a single vacuum cleaner. The purpose is to obtain an easy-to-use electric vacuum cleaner.

  The vacuum cleaner according to the present invention is provided in communication with the suction side of the electric blower and the suction tool, and includes a dust collection case removable from the vacuum cleaner main body, and the dust collection case is in communication with the suction tool. A dust collecting case main body having an opening on the suction side of the electric blower, a lid for opening and closing the opening of the dust collecting case main body, and a cyclone constituting a cyclone system detachable in the dust collecting case main body And a paper pack assembly, the cyclone dust collection assembly and the paper pack assembly being interchangeable with each other.

  According to the present invention, the cyclone type dust collection assembly and the paper pack assembly constituting the cyclone system which can be attached to and detached from the dust collection case main body are provided, and the cyclone type dust collection assembly and the paper pack assembly can be exchanged with each other. Therefore, it is possible to provide an easy-to-use vacuum cleaner that allows the user to select the cyclone dust collection method and the paper pack dust collection method according to the use and purpose with a single vacuum cleaner.
