Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust collector for an electric vacuum cleaner.

[0002]

2. Description of the Related Art Conventional dust collectors for electric vacuum cleaners have been designed exclusively for each type of electric vacuum cleaner, but recently, disposable dust collectors have been widely used.
Even with vacuum cleaners manufactured by different manufacturers, dust collectors of the same type can be commonly used.

For example, as shown in FIG. 7, an electric blower chamber in which an electric blower is arranged in the rear portion is formed, and a dust collection chamber in which a dust collecting bag 50 for collecting dust is freely taken in and out is formed in the front portion. A concave portion 51 is provided in the front portion of the bottom surface of the bottom surface, and a restraining body 53 that is rotatably attached by a spring 52 is provided in the upper portion of the front surface portion. Lower body 55 provided with an intake port 54 formed of a rubber body
In a vacuum cleaner having a structure in which a lid 56 that covers the dust collection chamber is arranged so as to be openable and closable from above, even if the size of the vacuum cleaner itself varies depending on the manufacturer or model, the shared disposable dust collector 57 is used. Can be used by the user.

As shown in FIG. 8, an example of the dust collecting device 57 is arranged in front of the dust collecting bag 50 for collecting dust and has a dust suction port 58 communicating with the inside of the dust collecting bag 50. A cardboard core 59 having a center is fixedly attached. The core 59 is provided with a lid 60 that can be slid up and down so that the dust inside the dust bag 50 does not dissipate to the outside when the dust collector 57 is taken out of the electric vacuum cleaner.
As shown in FIG. 8, this lid body 60 is provided with guide plates 61 on the left and right with a space between the surface of the mouth core 59 and the lid body 60 so that the lid body 60 can slide up and down. Groove 6
Two are provided.

The lid 60 has the same shape as the dust suction port 58 of the core 59,
Since a through hole 63 of the same size is provided and this through hole 63 is located in the vertical groove 62, the through hole 63 is fitted into the intake port 54 of the electric vacuum cleaner together with the dust suction port 58 of the core 59.

Then, the core 59 and the guide plate 61 are overlapped with each other, and the lower end portion 64 having a considerable thickness is fitted into the recess 51 provided in the lower front portion of the bottom surface of the vacuum cleaner.

Further, the upper end portion 65 of the lid body 60 is pushed downward by the above-mentioned restraining body 53 in the electric vacuum cleaner.
Therefore, the mouth core 59 to which the lid body 60 is attached by the guide plate 61 so as to be vertically slidable is attached to the front dust collecting chamber in the electric vacuum cleaner by the intake port 54, the concave portion 51 and the restraining body 53.

When removing the dust collector 57 from the vacuum cleaner, first, the pressing body 53 is rotated to rotate the lid 60 of the core 59.
The lower pressure is released, and the dust suction port 58 of the core 59 and the lid 6 are released.
The through hole 63 of 0 is removed from the intake port 54, and the lower end portion 64 is taken out from the concave portion 51 of the bottom surface of the dust collecting chamber of the vacuum cleaner. When the lid 60 is slid upward with respect to the core 59 as shown by the arrow Y in FIG. 8, the through hole 63 is located at the dust collecting port 5 of the core 59.
8, the dust suction port 58 of the mouth core 59 is closed by the lid 60, so that the dust in the dust collecting bag 50 does not dissipate to the outside. In this state, the dust collector 57 may be removed from the electric vacuum cleaner and discarded.

However, in the above-mentioned conventional structure, since the lid 60 is attached to the surface of the mouth core 59 by the guide plate 61 so that it can slide up and down, the lower end portion 64 fitted in the recess 51 becomes thick. ing. Therefore, the recess 51 can be used only in an electric vacuum cleaner having a wide width in which the lower end 64 is fitted, and cannot be used in an electric vacuum cleaner having a narrow width in the recess 51.

Further, the width of the restraining body 53 for pressing the upper end portion 65 of the lid body 60 downward has to be a size in which the thickness of the guide plate 61 and the thickness of the lid body 60 are combined. The dust collector 5 described above can be used only in the electric vacuum cleaner having the restraining body 53 having such a width.
7 can be shared.

[0011]

In the construction in which the lid body is attached to the mouth core to which the dust collecting bag is attached by the guide plate so as to be slidable in the vertical direction, the lower end of the mouth core is located between the mouth core and the guide plate and between them. Because of the total thickness of the lid in the above, it cannot be used in an electric vacuum cleaner having a narrow recess. Further, the dust collector cannot be used for an electric vacuum cleaner in which the pressing member for pressing down the upper end portion does not have the total thickness of the guide plate and the lid as the width of the pressing portion.

In order to solve the above-mentioned problems, the present invention has a dust collecting bag fixed to a mouth core, and the upper and lower ends thereof have only the thickness of the mouth core and open and close the dust entrance of the mouth core. (EN) Provided is a dust collector which can be freely used, and thus realizes a dust collector having high commonality.
