Abstract

Provided is a portable electric vacuum cleaner that can be used as a blower while suppressing an increase in size and weight. A portable electric vacuum cleaner (11) includes a cleaner body (15), a grip portion (28) for gripping the cleaner body, and a blower attachment (17) detachable from the cleaner body. The vacuum cleaner main body includes an electric blower (35), a dust collector, a main body connection port (19), an intake air passage (41), and an exhaust air passage (43). The dust collector accumulates the dust sucked in by the driving of the electric blower. The main body connection port is used to insert and remove accessories for the blower. The suction air passage communicates the main body connection port with the dust collector. The exhaust air passage communicates with the exhaust side of the electric blower. The exhaust air passage communicates with the blower fitting by inserting the blower fitting into the main body connection port.

Description

[0001] This application is based on Japanese Patent Application No. 2016-49517 (filing date: March 14, 2016), and enjoys the benefit of priority based on this application. This application incorporates the entire content of this application by reference. technical field [0002] Embodiment of this invention relates to the portable electric vacuum cleaner provided with the attachment for blowers attached to a vacuum cleaner main body. Background technique [0003] In recent years, there have been cordless portable vacuum cleaners in which a battery such as a secondary battery is incorporated as a power supply unit, and a user performs cleaning while holding a grip unit for transport. This type of portable electric vacuum cleaner is cordless and lightweight, so it can be used not only indoors but also outdoors. Therefore, it is expected that the range of use will be further expanded and the usability will be improved by adding a blower function. [0004] When an electric vacu...
