Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a canister type vacuum cleaner.

Conventionally, vacuum cleaners with cord reels have required great care when assembled. In other words, when setting the cord reel inside the main body case of a vacuum cleaner, many vacuum cleaners do not have a brake mechanism.
This had to be done while always preventing the cord from being wound up by the cord reel. In addition, even in models where the brake mechanism is provided as part of the cord reel unit, it is necessary to pull out the cord plug from the cord outlet after assembling the cord reel unit into the main body case; In consideration of ease of operation, the cord outlet portion of the main body case is set to have an opening area that is two to three times the area of the cord plug. Therefore, although the cord plug can be easily pulled out, if the brake function is released, it will be wound back into the main body by the winding action of the cord reel. In order to prevent this, it has become common practice to install a separate part at the cord reel outlet portion for locking the cord plug. However, this increases the number of parts and the number of assembly man-hours, which poses a problem for low-priced products.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a vacuum cleaner which is easy to assemble by preventing the cord from being wound up during assembly, and which can reduce the number of parts.

An embodiment of the invention is shown in FIGS. 1 to 4. In the figure, 1 is the lower case of the main body, and the upper case 2 of the main body and the outer lid 3 of the dust collection chamber make up the main body case 1'.
It consists of Reference numeral 4 denotes a cord reel having a built-in rotational force biasing means, which is rotatably attached to the partition wall 5. A cord stopper 5a is integrally formed with the partition wall 5 and closes the lower part of the cord outlet 13 provided at the rear lower part of the main body lower case 1. That is, a protrusion 1a that is integrally provided on the lower case 1 of the main body and forms the lower edge of the cord outlet 13
and the lower end of the cord stopper 5a is formed to such a width that the cord plug 7 provided at the tip of the cord 6 cannot pass through, thereby preventing the cord plug 7 from being rewound into the main body case 1'. I'm here. The upper end of the cord stopper 5a continues to a projecting wall 1b that is integrally provided with the lower case 1 of the main body and forms the upper edge of the cord outlet 13. Note that the cord outlet 13 of the lower case 1 of the main body is formed in a size that allows the plug 7 to be inserted easily. Reference numeral 5b denotes a locking protrusion integrally formed from the partition wall 5, and a locking protrusion 5b
A cord temporary fixing groove having a width slightly narrower than the outer diameter of the cord 6 is formed between the cord 6 and the cord 6. Reference numeral 8 denotes a cushioning rubber body, which prevents the cord plug 7 from hitting and damaging the main body case 1' during the winding action of the cord reel 4. Reference numeral 9 denotes an electric blower, which is arranged in parallel with the cord reel 4. Reference numeral 10 denotes wheels for moving the main body case 1' together with caster rollers 11.
is supported. 12 protects the main body case 1' with a bumper.

With this configuration, assembly can be performed as follows. That is, before installing the unit consisting of the cord reel 4 and the partition wall 5 in the main body lower case 1, the cord 6 is temporarily fixed by being sandwiched between the cord stopper 5a integrally formed from the partition wall 5 and the locking protrusion 5b. , remain in that state,
The unit consisting of the cord reel 4 and the partition wall 5 is installed in the main body lower case 1, and finally, while pulling the cord plug 7, the cord 6 is attached to the locking protrusion 5b.
Installation is completed by removing the temporary fixation. When installing the partition wall 5, since the cord outlet 13 is formed sufficiently large, the cord plug 7 is inserted into the cord outlet 13.
It can be easily taken out and the installation work can be done easily. In the state where the installation of the partition wall 5 is completed,
The cord stopper 5a partially closes the cord outlet 13 and prevents the cord plug 7 from being drawn into the main body case 1'. In this way, the unit of the cord reel 4 and the partition wall 5 can be installed without the trouble of manually preventing the cord 6 from becoming entangled.
Moreover, after the installation is completed, the cord plug 7 can be taken out by simply pulling it. Conventionally, the recess for temporarily fixing the cord provided in the bulkhead was generally located at the upper end, so when installing the cord reel bulkhead unit in the lower case of the main unit, hold the cord plug in your hand while temporarily fixing the cord. The assembly is now much easier than when the cord reel bulkhead unit had to be installed after removing the cord plug and pulling out the cord plug from the cord outlet of the lower case of the main body. Furthermore, since the cord stopper 5a is integrally provided in the partition wall 5, the number of parts is reduced, whereas conventionally one part was required to perform the function of a cord plug stopper at the cord outlet.

As described above, in the vacuum cleaner of the present invention, the cord outlet provided in the case body is large enough to allow the cord plug to pass through, and the cord stopper blocks a part of the cord outlet to prevent the cord plug from being pulled in. is provided integrally with the bulkhead for supporting the cord reel, which is formed separately from the main body case, and a protrusion that forms a cord temporary fixing groove with the cord stopper is integrally provided with the bulkhead, so that the cord cannot be wound easily. It is not necessary to assemble the product while preventing it from getting stuck by hand, making the assembly process easy.
Further, it is not necessary to wind up the cord during assembly or to provide a special part to prevent the cord plug from being pulled into the main body case after assembly is completed, resulting in a reduction in the number of parts.
