Description

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

Structure of the conventional example and its problems In FIGS. 1 to 4, reference numeral 101 indicates the lower part of the main body case, and on the upper part thereof, a dust collection lid 102 is provided on the front side, and a main body case upper part 103 is provided on the rear side. A storage section for housing a gap nozzle 104 and a shelf nozzle 105 is formed on the main body case top 103, and a storage lid 106 is provided so as to be rotatable and detachable around a hinge section 107 so as to cover the storage section. 108 is a cord winding button which can be slid up and down. 10
9 is a hole formed in the storage lid 106;
A rib 110 is formed on the inner periphery of 9.

In the above configuration, the cord winding button 103
When it is pushed all the way, it will be in a state as shown by the dashed-dotted line in FIG.
The upper surface portion 112 of the cord winding button 103 will be lowered. At this time, the storage lid 106
Since it is a resin molded part, due to dimensional variations or shrinkage due to environmental changes, the lower end of the rib 110 in the hole 109 of the storage lid 106 may shift and touch the upper part 103 of the main body case, as shown in FIG. There may be a difference a from the formed rib 113, and the upper surface part 112 of the cord winding button 103 is caught at this difference a, and the cord winding button 103
It happened that he did not return.

Purpose of the Invention The present invention solves the drawbacks of the conventional vacuum cleaner and provides an easy-to-use vacuum cleaner that does not interfere with the operation of the cord winding button even if there is a difference in level between the storage lid and the main body case. To provide a vacuum cleaner with excellent usability.

Structure of the Invention In order to achieve the above object, the present invention makes a cord winding button movable up and down through openings formed opposite to each part of the attachment storage section and storage lid formed on the main body case, From the opening edge of the attachment storage section and the storage lid, an upward rib and a downward rib are formed, the tips of which come into contact when the lid is closed, and the downward stroke of the cord winding button is higher than the height of the downward rib. It is made smaller, and the uppermost position is set to be approximately the same as the upper surface of the storage lid.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

In Figures 5 to 10, 1 is under the main body case,
On the front side of the wall 2, there is a dust collection section 4 for storing paper bags 3, and on the rear side, an electric blower 5 is arranged. A dust storage lid 6 is disposed at the opening of the dust storage section 4. The front side of the dust storage lid 6 is locked with a buckle 8 which is rotatably fixed to the intake port cover 7 and the lower body case 1 with a claw 9 hooked thereon. Reference numeral 10 denotes an intake port gasket, which is clamped and fixed between the intake port cover 7 and the lower body case 1. The cylindrical portion 11 of the intake port gasket 10 that protrudes toward the dust storage portion 4 side is
It is designed to fit into a hole 13 in the mouth core 12 of the paper bag 3. The bottom end of the mouth core 12 of the paper bag 3 is
A buckle 15 is inserted into the groove 14 of the lower body case 1, and the upper end is rotatably fixed to the lower body case 1.
It is locked with a claw 16. A support rubber front 17 is inserted into the front side of the electric blower 5, and contacts a rib 18 formed in a ring shape on the wall 2 to provide air tightness between the wall 2 and the electric blower 5. . In addition, the rear part of the electric blower 5 is connected to the rib 20 of the lower body case 1 via the support rubber back 19.
and a rib 22 on the main body case upper part 21 that covers the upper part of the electric blower 5. A gap nozzle 23 and a shelf nozzle 24 are housed on the upper surface of the main body case upper 21, and a storage lid 25 is disposed to cover the upper part thereof. A hinge portion 26 is provided on the rear side of the storage lid 25 so that the storage lid 25 can be rotatably and detachably fixed to the main body case top 21.

27 is the cord winding button, which is located on the top of the main case.
A pawl 29 is hooked onto the bearing portion 28 of No. 1 to prevent it from coming off upward. A compression spring 30 is disposed between the cord winding button 27 and the main body case top 21, and constantly urges the cord winding button 27 upward. Outer peripheral side surface 3 of cord winding button 27
1 is guided by an upward rib 32 of the main body case 21. This upward rib 32 is connected to the storage lid 25.
When the storage lid 25 is closed, the opening 34 is formed by coming into contact with a downward rib 39 formed on the storage lid 25,
The cord winding button 27 is inserted so as to be movable up and down. Also, if you press the cord winding button 27,
The brake lever 35 operates and the code reel 36
The brake roller 37 is then separated, and the cord reel 36 is rotated (due to the force of the leaf spring, although not shown). In addition, the cord winding button 2
7 is set to be smaller than the height of the downward rib 39, and the uppermost position is set to be substantially the same as the upper surface of the storage lid 25. That is, when the cord winding button 27 is pushed in to the maximum extent, the position of the upper surface 33 of the cord winding button 27 is between the upper end surface 38 of the rib 32 on the main body case top 21 and the hole 34 of the storage lid 25.
The rib 39 is located above the boundary between the rib 39 and the lower end surface 40 . (1st
0) 41 is the front wheel, and 42 is the rear wheel.

In the above configuration, when the cord winding button 27 is pressed all the way, it will be at the position indicated by the dashed line in FIG.
Since it is located above the lower end surface 40 of the rib 39 formed in the hole 34 of the storage lid 25, even if the uneven level a occurs as in the conventional example shown in FIG. There is no problem with the operation, and it always returns completely.

Effects of the Invention As is clear from the above description, the vacuum cleaner according to the present invention has a cord winding button formed through an opening formed opposite to each part of the attachment storage section and storage lid formed on the main body case. The opening edge of the attachment storage section and the storage lid form an upward rib and a downward rib, respectively, whose tips come into contact when the lid is closed, and the downward stroke of the cord winding button is smaller than the height of the downward rib, and the uppermost position is set to be almost the same as the top surface of the storage lid, so even if there is a difference in level between the upward rib and the downward rib, the top surface of the cord winding button will not get caught. Therefore, it is possible to provide a vacuum cleaner with extremely excellent usability without any problems.
