Description

  The present invention relates to a vacuum cleaner, and more particularly, to a means for preventing unattachment of a dust collection box of a vacuum cleaner.

  As for the dust collector of the conventional vacuum cleaner, the one using a dust bag is the mainstream. However, the dust collector having such a configuration needs to be replaced with a new dust collector every time the dust is full, and there is a problem that a purchase cost is generated.

  Against this background, in recent years, many people have adopted a dust collection box as a dust collector due to the need to reduce the cost of purchasing dust collection bags. In this way, there are two types of dust collectors that use dust collection bags and those that use dust collection boxes. However, when dust collection bags are used, in order to maintain airtightness, When using a dust collection box, from the viewpoint of improving the appearance, a cover body is provided to cover the top of each dust collection body, and the cover body does not close completely when the dust collection body is not installed. In order to prevent problems caused by the dust being directly sucked into the electric blower in this state, non-mounting prevention means are usually installed, and the location is a dust collection bag. If the dust collector bag is arranged so that the operating body of the non-mounting prevention means can be operated at the wick of the dust bag, and if a dust collection box is adopted as the dust collector, It is arranged so that the operating body of the non-mounting prevention means can be operated on the front wall of the dust collection box. There were many (e.g., see Patent Document 1).

  However, in the configuration of the conventional vacuum cleaner, when there are constraints such as the design for improving the appearance and the use of common parts for reducing the manufacturing cost, the non-mounting prevention means is provided in front of the dust collector. In particular, when a dust collection box is used for the dust collector, it is necessary to secure a dust collection volume in order to reduce the number of times the dust is thrown away, and a suction airflow to reduce clogging. From the viewpoint of securing the swirlability, it is necessary to make the dust collection box as large as possible without unevenness, and there is a problem that it is difficult to secure an installation space for the non-mounting prevention means.

  In addition, when a dust collection box is adopted as the dust collection body, a cover body that covers the upper side of the dust collection box is often formed of a transparent material so that the amount of dust can be confirmed from the outside. Has a problem in that the external projections and the like of the dust collection box can be visually observed from the outside, and if there are projections in various places, the appearance deteriorates.

  The present invention solves the above-mentioned conventional problems, and by making it possible to dispose the non-mounting prevention means while effectively using the space, the dust collection box is made as large as possible without unevenness, and the dust collection volume of the dust collection box The purpose of the present invention is to provide a vacuum cleaner with improved appearance by securing the swirlability of the suction airflow, improving usability, and consolidating the protrusions on the outer shell of the dust collection box.

When a maintenance brush is attached to a box, it is necessary to install the storage part, and at least there is a space for forming the storage part. While the space between the vacuum cleaner body and the dust collection box is effectively utilized, the operation body of the non-mounting prevention means is disposed on the vacuum cleaner body in the space, and the operation body is the dust collection box. By forming the operation body and the maintenance brush storage part in a positional relationship that allows the maintenance brush to be engaged with the attachment / detachment operation, the dust collection box forms an extra protrusion other than the maintenance brush storage part. It is not necessary to operate the non-mounting prevention means, the dust collection box can be enlarged as much as possible without unevenness, the dust collection volume of the dust collection box and the swirlability of the suction airflow can be secured, the usability can be improved, and the dust collection Appearance can be improved by consolidating the protrusions on the outer shell of the box.

  The vacuum cleaner of the present invention is provided with a dust collection box non-mounting prevention means while effectively utilizing the space created for forming the maintenance brush storage section, thereby rotating the dust collection volume of the dust collection box and the suction airflow. As well as improving the usability, it is possible to improve the appearance, and by consolidating the outer projections of the dust collection box.
