Electric vacuum cleaner

Abstract

Provided is a vacuum cleaner which enables a sheet to be automatically attached to / detached from a rotating brush of a suction implement for a floor, which brings about good floor polishing effects by attaching the sheet, and which can be quietly operated. When a floor polishing mode switch is operated, the sheet is attached to the rotating brush, and a first control means controls a rotation number so that the rotation number can be most suitable for good floor polishing using the attached sheet. A second control means weakens a suction force so that the sheet can be attached without a hindrance. Additionally, a peeling switch is operated so that a third control means reversely rotates the rotating brush at low speed, and the sheet is removed so as to be automatically wound back.

Description

technical field [0001] The present invention relates to an electric vacuum cleaner, in particular to the operation control of the electric vacuum cleaner, which installs a dust absorbing sheet in a rotating brush of a suction head to perform wiping and vacuuming in an optimal state that is effective and does not generate noise. Background technique [0002] There is known a conventional electric vacuum cleaner in which a rotating brush with a hair brush or a rubber scraper is housed in a cleaning head for the floor. The rotating brush is driven to rotate when cleaning with the vacuum cleaner, and can scrape the surface of the floor. dust, and sucks the scraped dust to clean efficiently. In addition, in the cleaning head for the floor with such a rotating brush, in order to be able to perform wiping suitable for room cleaning that has gradually increased the floor surface in residential houses in recent years, it has been proposed to attach a fluff-like member that is easy to...

Problems solved by technology

[0005] However, in the scheme disclosed in the above-mentioned Patent Document 1, since the cloth member is attached to the rotating brush, the cloth member is removed from the rotating brush when handling dust, because it must be peeled off, so it is disassembled. Very troublesome to operate

In addition, there is the following difficulty, that is, when replacing and installing, it is necessary to turn over the cleaning heads one by one, and to wind the cloth components on the rotating brush in a small space in the box, and it is necessary to pay attention to Do not attach adhesive fabric parts to locations other than the rotating brush, such as the head body box, and install them with great care

[0006] In addition, in the scheme disclosed in the above-mentioned patent document 2, since a cloth scraper portion for other purposes is formed at the front end of the scraper portion of the rotary brush, the structure of the rotary brush becomes very complicated. When the blades are worn out and need to be replaced, it is necessary to replace the entire rotating brush, and the reinstallation of the rotating brush itself is also very troublesome, so it is not ideal in terms of cost and practicality.
