Abstract

PURPOSE:To obtain an inexpensive vacuum cleaner whose running property is satisfactory and which does not damage the floor surface by providing a suction nozzle for executing a suction by approaching the floor surface by suction force of an electric air blower, and a blowing nozzle for blowing an exhaust of the electric air blower to the floor surface, and constituting a circulating air course of the suction nozzle, the electric air blower and the blowing nozzle. CONSTITUTION:When a mode switch (for instances a 'strong' mode switch) of an operating switch part 18 is depressed, input power corresponding to a 'strong' mode is supplied to an electric air blower 15, and also, an LED corresponding to the 'strong' mode is turned on, and the electric air blower 15 executes a suction by the maximum suction force. Also, by suction force of the electric air blower 15, dust on the floor surface is sucked together with an air flow from a suction nozzle 27, and this dust passes through a suction tube 28 and a suction passage 22 together with the air flow and is collected into a paper pack 16. Thereafter, an exhaust of the electric air blower 15 passes through an exhaust passage 20 and a blowing tube 29 and is blown to the floor surface from a blowing nozzle 26, and allows the dust on the floor surface to soar so as to be sucked easily. In such a way, dust which intrudes into a clearance of a carpet, etc., is also allowed to soar so as to be sucked easily.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an upright vacuum cleaner for use in general households.

[Prior Art] Fig. 6 is a perspective view showing a conventional upright vacuum cleaner described in, for example, Japanese Patent Publication No. 63-66526, in which the vacuum cleaner (1) has a built-in electric blower, etc. The main body (2) has a nozzle part (3) provided with a rotating brush "9" at the bottom of the main body (2).

Next, the operation will be explained.

When the start switch (5) is pressed, the motor (7) starts,
Clutch (9) starts rotating, resulting in rotation)'+'
(] ]-) begins to rotate around its axis, and its centrifugal force causes it to rotate around its fulcrum in the direction of the arrow in the figure, causing one end of the rotating piece (1]) to move into the moving member (12). Push the moving member (12) to the right after contacting it, and then turn the power switch (
13) to be in the ON state.

At this time, even if the start switch (5) is released, the motor (7) continues to rotate because the power switch (1B) is in the ON state.

In this state, when the rotating brush (6) wraps around the edge of the carpet and locks, the rotating brush side of the clutch (9) also locks, and the rotating piece (11) loses its centrifugal force and returns to its original position. The moving member (12) also returns to its original position.

As a result, the power switch (13) is turned off and the motor (7) is stopped.

[Problem to be solved by the invention] The conventional upright vacuum cleaner has four problems as described above.
