Description

[Detailed Description of the Invention] (a) Industrial Application Field The present invention relates to a dust collection lid that opens and closes an opening of a dust collection chamber formed in the front part of a main body, and an accessory storage chamber formed on the dust collection lid. This invention relates to a vacuum cleaner equipped with an opening/closing lid that opens and closes the vacuum cleaner.

(b) Prior art As this type of vacuum cleaner, for example,
There is a publication number 17042. In this vacuum cleaner, the dust collection lid that closes the opening of the dust collection chamber and the opening/closing lid that closes the opening of the accessory storage chamber are both removable, making opening and closing operations cumbersome and resulting in poor usability. The disadvantage is that it is bad.

In order to solve this problem, if the dust collection lid and the opening/closing lid are rotatably supported on the vacuum cleaner body and are connected and detached using a clamping means, the dust collection lid is always opened and closed when the dust collection lid is closed. The lid must be closed.

In other words, if the clamping means of the dust collection lid is configured to be tightened first, if the clamping means of the opening/closing lid is not completely tightened and gets stuck in the middle,
When the dust collection lid is opened without realizing it, the opening/closing lid is opened by the force of the dust collection lid, and the accessories stored in the accessory storage chamber are thrown out and scattered.

Also, when disposing of garbage, if you take out the dust box stored in the dust collection chamber and clean it with the accessories stored in the accessory storage chamber, the dust collection lid that was opened for garbage disposal will not allow you to take out the accessories. When the clamping means of the opening/closing lid is operated, it closes and the dust collection lid must be opened again, making the operation cumbersome.

(c) Problems to be Solved by the Invention The present invention has been made in view of the above-mentioned points, and the clamping means of the opening/closing lid is tightened before the clamping means of the dust collecting lid so that when the dust collecting lid is closed, it is necessary to close the dust collecting lid. The lid can also be closed.

(d) Means for Solving the Problems As shown in the drawings, the vacuum cleaner of the present invention has a structure including a dust collection lid 21 that opens and closes an opening of a dust collection chamber formed in the front part of the vacuum cleaner body 1; An opening/closing lid 28 for opening and closing an opening of an accessory storage chamber 27 formed on the upper surface side of the dust collecting lid 21 is rotatably supported on the main body 1, and the dust collecting lid 21 is locked to the main body 1. A clamping means 34 for locking the opening/closing lid 28 and a clamping means 33 for locking the opening/closing lid 28 to the dust collecting lid 21 are provided in the dust collecting chamber, and a spring 3 of the clamping means 33 of the opening/closing lid 28 is provided in the dust collecting chamber.
7 is made weaker than the spring 41 of the clamping means 34 of the dust collecting lid 21.

(E) Effect With the above structure, the spring 37 of the clamping means 33 of the opening/closing lid 28 is weaker than the spring 41 of the clamping means 34 of the dust collecting lid 21, so that the operating force of the clamping means 33 of the opening/closing lid 28 is reduced by the concentration. The operating force is smaller than the operating force of the clamping means 34 of the dust lid 21, and therefore, when the dust collecting lid 21 and the opening/closing lid 28 are closed, the clamping means 33 of the opening/closing lid 28 operates before the clamping means 34 of the dust collecting lid 21. If the dust collection lid 21 is closed, the opening/closing lid 28 will also be closed, so that the attached parts 26 will not be scattered when the dust collection lid 21 is opened. Also, the dust collection lid 21
Since the opening/closing lid 28 can be opened before the dust collecting lid 21 is closed, the accessory part 26 can be taken out without closing the dust collection lid 21.
