Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor nozzle of an electric vacuum cleaner used mainly at home.

[0002]

2. Description of the Related Art Conventionally, a floor nozzle of this type of vacuum cleaner has a structure as shown in Japanese Utility Model Publication No. 61-179797. 5 to 7, reference numeral 1 denotes a cleaner body (hereinafter referred to as a body), which is a motor chamber 3 having a motor-2 built in below.
A dust collecting chamber 4 is formed on the upper suction side, and a handle 5 is arranged on the upper portion. 6 is a motor exhaust port provided in the motor chamber 3, 7 is a lid that covers the dust collection chamber 4 and the motor exhaust port 6, and a partition 8 separates the suction side and the exhaust side. 9
Is a lid exhaust port formed in the lid, and the exhaust filter 10 is detachably arranged. A floor nozzle 11 is rotatably supported by the main body 1 and has an intake port 12 formed at the lower front side. Reference numeral 13 denotes a rotary brush which faces the intake port 12, and is driven by the motor-2 via the belt 14. Reference numeral 15 is a hose having one end connected to the intake port 12 and the other end connected to the dust collecting chamber 4, and 16 is a dust collecting bag disposed in the dust collecting chamber 4 and connected to the suction side of the hose 15. At both ends of the rotary brush 13, brush bodies 18 in which edge brushes 17 are obliquely outwardly planted in the circumferential direction are attached integrally with the rotary brush 13, and the edge brush 17 is made to face the width of the floor nozzle 11. Also,
Both sides 1 of the floor nozzle 11 against which the brush body 18 is held
The reference numeral 9 is opened to have substantially the same size as the brush body 18, and the edge brush 17 faces the width of the floor nozzle 11.

[0003]

In the above-mentioned structure, since the edge brush faces the full width of the floor nozzle, it is possible to clean the full width of the floor nozzle. Although it has become possible to expand the possible range, with such a structure, both sides of the floor nozzle are opened in a shape substantially the same as the brush body to face the brush body rotating at high speed. Therefore, when a user gets away from the vacuum cleaner while operating the vacuum cleaner by calling while cleaning, or when the user is not looking at the front, that is, the floor nozzle side while using the attachment, an infant or the like mistakenly brushes. There was a problem that you could get cuts by touching with your hands or fingers. The present invention solves such a problem.

[0004]

In order to achieve the above-mentioned object, the present invention has a floor nozzle rotatably supported by a cleaner body, and a rotary brush built in the floor nozzle. Edges are provided at both ends of the rotary brush. A brush body in which brushes are circumferentially planted in a diagonal direction is attached to a rotating brush, and opening openings of substantially the same shape as the brush body are provided on both side surfaces of a floor nozzle that holds the rotating brush. An opening / closing lid for opening / closing the opening is provided, and a tension spring is attached between the opening / closing lid and the cleaner body, and a compression spring is attached between the opening / closing lid and the floor nozzle.

[0005]

According to the present invention, the opening / closing of the opening / closing lid is interlocked with the rotation of the cleaner main body by the above-mentioned construction, and the opening / closing lid is opened by the tension spring when the cleaner main body is operated, so that the cleaner main body is upright. In the state, it can be used by closing with a compression spring.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In the figure, reference numeral 21 denotes a cleaner body (hereinafter referred to as a body), a motor chamber 23 having a motor 22 built therein is formed below, a dust collecting chamber 24 is formed on an upper suction side, and a handle 25 is arranged on an upper portion. ing. 26 is a motor exhaust port provided in the motor chamber 23, 27 is a lid that covers the dust collection chamber 24 and the motor exhaust port 26, and a partition 28 separates the suction side and the exhaust side. Reference numeral 29 denotes a lid exhaust port formed in the lid 27, to which an exhaust filter 30 is detachably arranged.
A floor nozzle 31 is rotatably supported by the main body 21 and has an intake port 32 formed in the lower front direction. 33 is an intake port 32
Bearings 34, 35 (not shown)
And is rotatably driven by a motor-22 via a belt 36. 37 is a hose having one end connected to the intake port 32 and the other end connected to the dust collecting chamber 24, and 38 is a dust collecting bag disposed in the dust collecting chamber 24 and connected to the suction side of the hose 37.

Reference numeral 39 denotes a brush body integrally attached to a rotary brush shaft 40 projecting outward from both ends of the rotary brush 33. An edge brush 41 is obliquely outwardly planted in the circumferential direction on the outer periphery, The edge brush 41 faces the width of the floor nozzle 31. Further, on both side surfaces of the floor nozzle 31 with which the brush body 39 is held, opening openings 42 opened to have substantially the same size as the edge brush 41 are provided. The dust scraped up by the edge brush 41 rotating at high speed enters the intake port 32 through the opening 42. Reference numeral 43 denotes an opening / closing lid that is attached to the opening opening 42 of the floor nozzle 31 and opens / closes the opening opening 42. A tension spring 44 is stretched between the opening / closing lid 43 and the locking projection 45 of the main body 21 and the opening / closing lid 43. A compression spring 46 is attached between the floor nozzles 31 to bias the open / close lid 43. Tension spring 44
The compression spring 46 is set so that the load is zero when the main body 21 is upright (FIG. 1) and the load is not applied to the opening / closing lid 43. The load of the tension spring 44 is set to be larger than the load of the compression spring 46 in the use state.

Next, the operation of the structure of one embodiment will be described. When the motor 22 is operated, the rotating brush 33 and the brush body 39 are rotated by the belt 36, and the user holds the handle 5 and pivots the main body 21 to incline it obliquely to operate the handle 5 back and forth to move the floor nozzle 31 as well. Although it moves back and forth, at this time, the tension spring 44 extends due to the rotation of the main body 21, the opening / closing lid 43 moves toward the rear of the main body 21, and the edge brush 41 is exposed. The dust-containing air sucked by the motor 22 is sucked into the intake port 3
2 through the hose 37 and collected in the dust bag 38, only clean air passes through the motor 22 and the motor exhaust port 26, and is further filtered by the exhaust filter 30 of the lid exhaust port 29. It is released to the outside. When cleaning the corner between the wall and the floor or the corner between the furniture and the floor,
The floor nozzle 31 is brought close to the part and the dust is scraped up by the ed brush 42, and the dust enters the intake port 32 from the opening port 42 and is absorbed. When the user gets a telephone call during cleaning and leaves the cleaner while the cleaner is running or when using an attachment, the cleaner body is set upright, but at this time, the compression spring 46 presses the opening / closing lid 43. Then, the opening 42 is closed.

[0009]

As described above, in the floor nozzle of the electric vacuum cleaner of the present invention, the opening / closing lid is opened to expose the edge brush when the cleaner is in use, that is, when the cleaner body is tilted. Cleaning and corners on the floor and on the gown
It is possible to clean the floor nozzle to the full width of the floor nozzle during cleaning, so that the cleaning residue can be reduced to 0 and the cleaning range can be expanded and the cleaning efficiency can be improved. When the user gets a telephone call during cleaning and leaves the cleaner while the cleaner is running or when using an attachment, the cleaner body is set upright but the opening is closed by the opening / closing lid. It is possible to provide a very safe electric vacuum cleaner that prevents cuts on the fingers and hands of infants and the like.
