Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a suction tool for a vacuum cleaner equipped with a lint catcher for removing lint, cotton waste, etc. entangled in carpets, etc.

PRIOR ART Many proposals have been made to date for installing a so-called lint catcher on the bottom of the suction device of a vacuum cleaner, which is constructed by densely flocking short slanted bristles (Japanese Utility Model Publication No. 50268, Japanese Patent Laid-open Publication No. 1983). -10967).

This lint remover works so that when the floor suction device is moved in a direction opposite to the slope of the inclined bristles, the inclined bristles function to scrape off lint from the surface to be cleaned, and when moved in the opposite direction, the lint is removed from the bristles. is detached, and the lint is sucked through the detached lint suction port.

Incidentally, conventional vacuum cleaner suction tools have been designed with lint traps attached at the front and rear of the suction passage at the bottom thereof, flat against the surface to be cleaned.

The problem that the invention aims to solve However, since the length and softness of the pile differs depending on the type of carpet, if the lint catcher is flat against the carpet surface, for example, in the case of a long pile carpet,
If the sloped bristles of the lint remover come into contact with the carpet surface too strongly, the sloped bristles will be defeated by the carpet, causing the bristles to reverse, making the lint removal effect ineffective, or conversely, if the bristles are too short, the threads may There was also a shortcoming in that the lint catcher did not come into contact with the carpet surface, making the lint catcher ineffective.

On the other hand, it has been considered that the installation height of the lint catcher can be changed depending on the carpet, but in this case, the switching mechanism increases the number of parts, leading to an increase in cost, and it is necessary to frequently replace the lint catcher for the first time depending on the carpet. It was a bit of a nuisance.

The present invention eliminates the above-mentioned conventional drawbacks and provides a suction tool for a vacuum cleaner with good lint removal performance.

Means for Solving the Problems In order to solve these conventional drawbacks, the present invention provides a suction passage extending substantially linearly at the bottom of the suction device main body,
A lint catcher is installed before and after this suction passage to remove lint entangled in the carpet, etc., and this lint catcher is formed of bristles that are slanted toward the suction passage. should be parallel to the cleaning surface, flush with the bottom of the suction tool body, or slightly recessed, and the lint catcher at the rear of the suction passage should not be farther from the cleaning surface than the suction passage. They were installed at an angle like this.

Function In the above configuration, one lint catcher catches the lint entangled in the carpet etc. according to the back-and-forth movement of the suction tool body, and the previously caught lint is released from the other lint catcher. and is sucked through the suction passage.

Furthermore, when moving the suction tool body forward, the operating force that presses the suction tool body against the carpet acts as a force, and the best point for picking up lint from the rear lint catcher changes depending on the type of carpet. Since the similar lint catcher is installed at an angle, the best position is somewhere to catch the lint reliably.

In addition, when moving the suction tool body backwards, the lint catcher at the front will reliably catch the lint even if it is parallel, since no force is applied to the suction tool body as described above. .

Example Examples thereof will be described below based on the accompanying drawings.

In the figure, reference numeral 1 denotes the main body of the suction device, on which a suction joint 2 is attached so as to be able to move up and down, and a rotary pipe 3 is rotatably attached to the suction joint 2 via a retaining ring 4. There is.

5 is a connecting pipe, and 6 is a carpet sled, which has an opening 7 in the center and suction passages 8 on the left and right sides of the opening 7.

A brush 9 is provided parallel to the rear of the suction passage 8 and is fixed to the carpet sled 6.

Reference numeral 10 denotes a front rotating roller, which, together with the rear rotating roller 11, prevents the bottom surface of the carpet sled 6 from coming into contact with the floor surface when cleaning the floor surface, etc., and prevents the bottom surface of the carpet sled 6 from coming into contact with the floor surface etc. I try to maintain a certain distance between them.

A bumper 12 is provided around the suction tool main body 1 in order to prevent damage to furniture etc. even if it collides with them during cleaning.

At the front of the opening 7 in the center of the suction passage 8, a lint catcher 13 with bristles inclined toward the suction passage 8 is provided recessed from the carpet sled 6 and parallel to the surface to be cleaned.
In addition, the brush 9 is separated from the rear part so that the bristles of the bristles are inclined toward the suction passage 8 side.

The lint catcher 14 is provided at an angle so as to be recessed from the carpet sled 6 at the farthest point from the suction passage 8.

With the above configuration, when cleaning is to be performed, the rotary pipe 3 is connected to the cleaner main body via an extension pipe, a hose, etc., and the suction tool is operated on the surface to be cleaned to suck in dirt.

When the suction tool is pushed forward, the lint catcher 14 located at the rear of the suction passage 8 sweeps over the surface of the carpet as its bristles are laid on the side of the suction passage 8, and picks up the lint on the surface of the carpet.

At the rear of the suction device, when the suction device is pushed forward, the operating force acts as a downward force through the rotating pipe 3, and the pile length and softness of the carpet vary depending on the type of carpet. However, since the lint catcher 14 is installed at an angle, the best point for picking up lint will change depending on how far the suction device sinks into the carpet. This position allows you to remove lint.

When the suction tool is pulled rearward, the lint picked up by the lint catcher 14 is returned to the carpet surface by the force of the lint catcher 14 because the bristles of the lint catcher 14 are in the direction of removal.

A suction passage 8 passes over it and sucks up the lint.

Furthermore, a lint catcher 13 in front of the suction passage 8 removes lint from the carpet surface in the same manner as the lint catcher 14 described above.

However, when pulling the suction device backwards, it is different from when pushing it forward.
Since there is almost no force pushing the suction device downward, it does not sink into the carpet due to operating force, and even if the lint catcher 13 is installed parallel to the carpet surface, it has sufficient lint collecting performance. can demonstrate.

In addition, the lint catcher 13 is recessed from the lower surface of the carpet sled 6 so that the lint catcher 13 comes into close contact with the carpet due to the suction force of the suction tool.

Experiments have shown that if the tip of the lint remover 13's bristles protrude beyond the carpet sled 6, the carpet's bristles and lint remover 13's bristles come into contact too strongly, making it difficult to remove lint.

Also, if the carpet is recessed too far from the carpet sled 6, short piles of the carpet will not come into contact with the lint catcher 13 and will not be removed at all, and the end of the pile of the lint catcher 13 will be lower than the bottom surface of the carpet sled 6. The lint removal performance on various carpets was the best when I used 2TrrIn.

Regarding the lint remover 14, the tip of the pile on the side of the suction passage 8 is set to 0 to 2 rran, and the tip of the pile farther from the suction passage 8 is set to 1.5rIrIn to 3.51rr! When installed at an angle in the direction of n, it exhibits sufficient lint removal performance for various types of carpets, from needle punch carpets to tufted carpets.

Effects of the invention As described above, according to the invention, it is possible to exhibit reliable lint removal performance on various carpets with a very simple configuration, and its practical value is extremely large.
