Problems solved by technology

[0014] However, this motor overload prevention device 20 requires an overly complicated structure
Furthermore, in order to ensure sufficient sealing of the opening / closing member 25, the opening / closing member 25 is usually made of an expensive material such as rubber, thus increasing the manufacturing cost

Embodiment Construction

[0034] Hereinafter, the present invention will be described in detail by referring to the accompanying drawings. Throughout the specification, those with figure 1 and Figure 2A - Similar or identical components in the background art shown in B will use the same reference numerals, and their structures and functions will be further described in detail on the basis of the above description.

[0035] Figure 3A -C and Figure 4A -B is a view of a motor overload prevention device used in a vacuum cleaner according to a first preferred embodiment of the present invention.

[0036] Referring now to FIGS. 3 and 4 , a first preferred embodiment of the motor overload prevention device 100 includes a windshield body 101 and an elastic member 107 .

[0037] As shown, a tapered opening / closing portion 101a is formed at one end of the windshield body 101, while the other end of the windshield body 101 is hinged to the partition 15 of the vacuum cleaner. In more detail, the windshield...

Abstract

A motor overload preventing apparatus for a vacuum cleaner includes a damper body and an resilient member. The damper body has an opening / closing portion formed on one end, to selectively block a tapered aperture of a body frame of the vacuum cleaner, and the opening / closing portion is tapered to correspond in shape with the aperture. The resilient member resiliently biases the opening / closing portion toward a direction of closing the aperture. The damper body is movably disposed to rotate so as to selectively open and close the aperture, and to this end, it is preferred that the damper body is connected by a hinge to the body frame. Satisfactory sealing can be ensured even when there is surface contact between the opening / closing portion and the aperture without requiring additional material, such as a rubber. Additionally, the number of components can be reduced, and with the omission of flexible material, such as rubber, the manufacturing costs can be reduced.

Description

technical field [0001] The present invention relates generally to a vacuum cleaner and, more particularly, to a device for preventing overloading of a drive motor when the drive motor is generating suction force for the vacuum cleaner. Background technique [0002] Generally, a vacuum cleaner sucks in air and the dust it carries by utilizing a suction force generated by a driving motor. figure 1 Such a common vacuum cleaner is schematically shown in . [0003] See figure 1 , a common vacuum cleaner includes: a main body 10, in which a drive motor 1 is installed; a suction pipe 3, which is in fluid communication with the main body 10 at one end thereof; and a suction nozzle 5, which is formed on the suction pipe. 3 from the end connected with the main body 10 on the other end. The main body 10 includes a motor housing part 11 in which the drive motor 1 is placed, and a dust collecting housing part 13 which includes a filter part 7 for filtering and collecting dust passing ...
