JPH1043098A - Suction inlet for floor of electric vacuum cleaner - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a suction inlet for floor of an electric vacuum cleaner capable of effectively cleaning refuse on a floor surface close to furniture. SOLUTION: When a bumper 5 provided on the front of a suction inlet for floor is retracted as resisting energizing force, a suction channel 15 is formed between a wall 13 in front of the inlet for floor and a floor surface 10. And at the time when the bumper 5 comes into contact with a wall or furniture 13, etc., the bumper 5 moves backwards as resisting energizing force, and a suction channel 15 is formed between the wall 7 in front of the suction inlet for floor and the floor surface 10. In a result, refuse left at corners between a wall or floor and furniture can be effectively removed by suction.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor suction port of a vacuum cleaner.

[0002]

2. Description of the Related Art In recent years, there has been an increasing demand for a floor suction port of an electric vacuum cleaner capable of collecting dust near furniture and the like without cleaning the furniture and the like when cleaning.

A floor suction port of a conventional vacuum cleaner will be described with reference to FIGS. 3 and 4. FIG.

As shown in the figure, an electric blower (not shown)
A handle 17 is provided on a main body 16 having a built-in, and a rotating brush 18 is provided inside the main body 16 and rotated by a motor, and a floor suction port 20 for cleaning a carpet 19 and the like is connected to a connection pipe 21.
Connected through. The floor suction port 20 is provided with wheels 22 and a bumper 24 for preventing damage to furniture 23 during cleaning is formed of soft vinyl chloride or the like. The upper suction port main body 25 and the lower suction port main body 26 form a bumper 24. Floor suction port 20
The front is fixed. A suction port 27 is provided on the lower surface of the floor suction port 20.

[0005]

When the bumper 24 comes into contact with the furniture 23 or the like in the floor suction port of such a conventional vacuum cleaner, the suction air blows on the front part of the suction port 27. The garbage in the part of I was not removed.

This is because the lower suction port main body 19 is not provided with a gap from the floor surface in order to increase the suction pressure on the lower surface of the suction port 27 and improve the dust collection performance. This kind of problem has conventionally occurred. Was.

An object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to provide a floor suction port of a vacuum cleaner capable of cleaning dust on a floor near furniture.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention has been made to solve the above-mentioned problems. When the bumper of the suction port comes into contact with a wall, furniture, etc., the bumper moves rearward against the urging force, and the suction passage for the floor is formed. A suction flow path is formed between the front wall and the floor, and the suction force of the suction port is transmitted to furniture and the like to remove dust, thereby eliminating generation of remaining dust.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION
A retractable bumper is attached to the front of the floor suction port, and a suction flow path is formed between the front wall of the floor suction port and the floor when the bumper retreats against the biasing force. When the bumper at the suction port comes into contact with a wall or furniture, the bumper moves rearward against the biasing force, forming a suction flow path between the front wall of the floor suction port and the floor surface. Then, the suction force of the suction port is transmitted to furniture and the like to remove garbage, thereby eliminating garbage remaining.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

As shown in the figure, a pair of guide ribs 3 are provided in front of an upper suction port main body 1 at the end thereof and have a retaining claw 2 extending obliquely downward. The front wall of the lower suction main body 6 is formed separately from the lower suction main body 6 on a bumper 5 which is fitted into the guide rib 3 and slides along the guide rib 3. 7 and the lower suction port main body 6 and the front wall 7
A suction port 8 is formed between the guide rib 3 and the bumper 5 so that the spring 9 that always presses and moves the bumper 5 forward.
It is provided between them. A rotary brush 11 is provided on the suction port 8 so as to be in contact with a floor 10 such as a carpet.
2.

In the above configuration, when the floor surface 10 not in contact with the furniture 13 or the like is being cleaned, the bumper 5 provided in front of the floor suction port 12 is actuated by the spring pressure of the spring 9 as shown in FIG. The lower surface of the lower suction port main body 6 and the lower surface of the front wall 7 move to the lower position on the front side to form the suction port 8 on the same plane, and the rotation of the rotating brush 11 causes dust on the floor surface 10 to move to the floor. The suction in the suction port 12 is performed.

Next, when the bumper 5 contacts the furniture 13 or the like in order to clean the floor 10 near the furniture 13 or the like, the bumper 5
Retreats while moving diagonally upward along the guide ribs 3 against the spring pressure of the spring 9, and as shown in FIG. 2, a gap 14 is formed between the lower surface of the front wall 7 and the floor 10. A dust suction channel 15 is formed as shown by an arrow in combination with the suction port 8 so that the floor 10 near the furniture 13 can be cleaned.

[0014]

According to the present invention, when the bumper provided at the front portion of the suction port main body abuts against a wall or furniture, and retreats against the urging force, the front wall of the floor suction port and the floor surface are retreated. The floor suction port of the electric vacuum cleaner can clean the dust on the floor near the furniture or the like from the suction flow path formed between the floor and the furniture. Further, when it does not come into contact with furniture or the like, no suction flow path is formed by the bumper due to the urging force.
