Description

[Detailed description of the invention] This invention relates to a vacuum cleaner equipped with a cord reel.

First, a conventional general example is shown in FIGS. 1 and 2.
Reference numeral 1 denotes a main body case, and a dust collection case 2 containing a filter is connected to the main body case 1 by a clamp 3. Inside the main body case 1 are an electric blower chamber 5 that houses an electric blower 4 and a cord reel 6.
A cord reel chamber 7 for accommodating the cord reel is separated by a partition wall 8. The cord reel 6 has a drum 10 around which the cord 9 is wound, and a barrel 12 in which the whole body 11 is housed. One end of the cord reel shaft 13 that rotatably holds the cord reel 6 is held by a cylindrical holding portion 14 formed on the rear wall of the main body case 1, and a locking pawl 15 formed at the other end of the cord reel shaft 13. is resiliently engaged with a holding portion 16 formed on the partition wall 8 while being prevented from rotating. The cord reel shaft 13 is formed with a full-length hook part 17 for holding the inner end of the full-length coil 11, and a full-length hook part 18 for holding the outer end of the full-length coil 11 is formed on the barrel 12. There is. A holding plate 19 located on the opening surface of the barrel 12 and holding down one side of the full-length barrel 11 has locking claws 20 formed at both ends thereof engaged with pins 21 erected on the outer periphery of the barrel 12. It is fixed by this.

Next, a brake lever 23 is rotatably connected to a shaft 22 erected on the rear wall of the main body case 1 while being biased in one direction. A roller 24 is attached to the brake lever 23 and wedged between the outer periphery of the cord reel 6 and a fixed surface (not shown) facing the outer periphery.

When assembling something like this, first use the barrel 12.
Store the Zenmai 11 in the Zenmai 11, hook the outer end of the Zenmai 11 on the Zenmai hanging part 18, insert the cord reel shaft 13 into the center of the cord reel 6, and hook the Zenmai 11 on the Zenmai hanging part 17. The end is hooked, and then the presser plate 19 inserted through the cord reel shaft 13 is connected to the cord reel 6, but at this time, the entire body 11 is flipped, making assembly difficult. In particular, when winding the entire cord 11, the center of the cord reel 11 may jump out along with the cord reel shaft 13, resulting in extremely poor workability. Furthermore, since the cord reel 6 is attached separately from the brake lever 23, the cord reel 6 must be attached to the main body case 32 while the brake lever 23 is retracted outward against the urging force. It is also difficult to assemble.

This idea was made in consideration of these points, and we created a vacuum cleaner that can be easily assembled without having to release the whole thing onto a cord reel, and can also be assembled automatically by omitting the number of parts and assembly points. The purpose is to obtain information.

In this invention, a cord reel shaft having a full hook part that holds the inner end of the full hook is inserted into the cord drill, and the full hook is held by the full hook part. By integrally forming the presser plate that presses the edge, the entire movement can be stabilized as soon as the cord reel shaft is inserted into the cord reel, and the number of parts and assembly points can be reduced to allow automatic assembly. It is composed of

An embodiment of this invention will be explained based on FIGS. 3 to 5. Components that are the same as those described in FIGS. 1 and 2 are designated by the same reference numerals, and the description thereof will be omitted. The cord reel shaft 25, which rotatably holds the cord reel 6 and is installed on the holding parts 14 and 16 of the cord reel chamber 7, has a full length hanging part 17 that holds the inner end of the full length 11, A presser plate 26 that presses the side edges of 11 is integrally formed. Furthermore, a shaft portion 27 and a spring hanging pin 28 for rotatably holding the brake lever 23 are provided upright on the holding plate 26. A spring 30 is tensioned between this spring hook pin 28 and a spring hook pin 29 provided upright on the brake lever 23.

In such a configuration, as shown in FIG. 4, the Zenmai 11 is stored in the barrel 12 while the outer end of the Zenmai 11 is engaged with the Zenmai hook part 18, and the inner end of the Zenmai 11 and When inserting the cord reel shaft 25 into the cord reel 6 while engaging the full hook portion 17 of the cord reel shaft 25, the full hook 11 quickly moves the side edge to the presser plate 2.
6, it is stable and does not bounce out of the barrel 12. Next, attach the brake lever 23 to the shaft portion 27.
and attach spring 3 to spring hanging pins 28 and 29.
0, the cord reel 6 and brake lever 23 are assembled as a unit.
In this way, the Zenmai 11 is played on the presser plate 26 without being played.
Since the holding plate 26 is integrally formed with the cord reel shaft 25, the number of parts and assembly locations are small, and therefore, the assembly work can be automated. Furthermore, when assembling the cord reel 6 to the main body case 1, there is no need to perform the troublesome work of assembling the brake lever 23 held by the main body case 1 while retracting it outward.

Since this invention is constructed as described above, when assembling Zenmai and the cord reel shaft to the cord reel, the ejecting motion of Zenmai can be quickly suppressed and stabilized by the presser plate, and the cord reel By integrally forming the holding plate on the shaft, the number of parts and assembly locations can be reduced, and the assembly work can be automated.
