Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a vacuum cleaner having an indicator that operates by sensing the amount of dust in a dust collection chamber.

BACKGROUND ART 2 The structure of a conventional vacuum cleaner of this type will be described with reference to the drawings.

6 to 9, reference numeral 1 denotes a vacuum cleaner body with a built-in fan motor 2, a housing for a cord 3, etc., and a dust box 5 equipped with a filter 4 in front of the fan motor 2. There is.

The dust box 5 is detachably attached to the vacuum cleaner main body 1 by a dust box locking part 6 provided below and a buckle 7 rotatably provided above.

Reference numeral 8 denotes an intake port provided in front of the dust box 5 into which a hose (not shown) is inserted.

Next, 9 is an indicator pipe provided above the vacuum cleaner main body 1, and inside it is an indicator 10,
It has a spring 11 and an indicator pipe 9 on one side.
It is fixed to an indicator lid 13 having an indicator hole 12 that allows air to flow into the interior. Further, an indicator elbow 14 is provided on the opposite side of the indicator pipe 9, and the tip thereof is fixed to an air passage 15 communicating with the inside of the dust box 5.

3 vanes, 16 is a lid body for closing the upper opening of the indicator pipe 9 portion of the cleaner body 1, an air intake port 17 provided in a lattice shape, and an upper direction indicator 10
It has a window 18 for viewing. As shown in FIG. 9, each air intake port 17 is provided with hole-hiding ribs 19 at the bottom so that the inside cannot be seen even when viewed from above by the user.
An air intake opening of 2° is provided between the cylinder 19 and the perforated cylinder 19 which match with each other. Further, an overhanging rib 21 is provided above the air intake port 2o so that the air intake port 2o cannot be seen from above.

The above is the conventional configuration, and its operation will be explained. When dust accumulates inside the dust box 6, the pressure inside the dust box 5 decreases.

Since the indicator pipe 9 communicates with the inside of the dust box 5 via the air passage 15 and the indicator elbow 14, the indicator 10 is connected to the indicator lid 13.
The indicator elbow 14 begins to move against the force of the spring 11 due to the external pressure being applied to the side surface. When the indicator 10 moves, air flows in from the indicator pipe 9 and the gap provided on the outer periphery of the indicator 10 and reaches the inside of the dust box 5. This air enters through the air intake port 17 provided in the lid body 16, passes through the entirety of the indicator lid 13, and is guided into the interior of the indicator pipe 9.

Problems that BA is trying to solve In such conventional vacuum cleaners, indicator 10
All the air necessary to operate the system is taken in through the air intake port 17. This air must apply a large pressure to the indicator 10, which requires a large area. Therefore, conventionally, a plurality of air intake ports 17 were arranged in a grid pattern as shown in FIG. In this conventional ρ, a
×8 (pieces)=length of Sa is required. but,
In this configuration, since the air intake ports 20 and the perforated cylinders 19 are arranged alternately, a very large area is required on the top surface of the lid body 16 in order to secure the air passage area necessary for moving the indicator 10. It was not possible to reduce the size of the lid 16, and it was also impossible to reduce the size of each component in the section e of the in-jig 5 pager pipe.

However, since the inside is visible when the user looks from above, an overhang rib 21 is also required, and the lid body 1
Instead of increasing the material cost of 6, the air intake 17
Because the distance between them is large, there are restrictions in terms of design.

Furthermore, as can be seen from the arrows shown in FIG. 9, the structure is such that the air collides with the ribs while moving from the air intake port 17 to the air intake port 20, resulting in poor air intake efficiency. Requires a large air passage area.

In addition, as mentioned above, the air flow is not smooth and the air flowing out from the air intake ports 20 adjacent to each other collides with each other, which is a disadvantage. had.

The present invention solves these problems, and aims to provide a vacuum cleaner that exhibits effects such as miniaturization of the air intake port and improved operation of the indicator.

Means for Solving the Problems In order to solve the above problems, the present invention arranges air intake ports and reinforcing ribs alternately, and the reinforcing ribs make the vertical ribs extending downward and the air intake ports invisible from above. It is formed by horizontal ribs, and the reinforcing ribs and ribs in front of the horizontal ribs are also recessed downward to provide an air passage.

Effect of the present invention With the above-described configuration, not only is it possible to reduce the area of the lid for securing the air passage area, but also the air flow is smooth and the indicator operates well. be.

EXAMPLES Hereinafter, examples of the present invention will be described with reference to the drawings.

1 to 5, 31 is a fan motor 32
It is a vacuum cleaner body with built-in components, etc., and this fan motor 3
2 has a 7-page dust collection chamber 34 in front of which a paper bag 33 is attached. A lid 35 is placed above the dust collection chamber 34.
is provided, and the rear thereof is rotatably attached to the main body cover 36. Further, the front part of the lid 35 is fixed to the cleaner main body 31 via a buckle 37.

Reference numeral 38 is a paper bag supporter that fixes the lower part of the opening 39 of the paper bag 33, and the opposite side of the opening 39 is supported by riding on the paper bag holder 4°.

Further, the front of the lid 35 has an intake port 41 for inserting a hose (not shown), and a rotating body 42 is provided inside the intake port 41 so that the hose can freely rotate.
is supported from below via the inner lid 43.

Next, 44 is an indicator pipe provided above the lid 35, which has an indicator 45 and a spring 46 inside, and one side of which is an indicator lid 48 with an indicator hole 47 through which air flows. Fixed. Further, an indicator elbow 49 is provided on the opposite side. As shown in FIG. 3, the tip of the indicator elbow 49 is inserted into an elbow flange 5° provided on the inner cover 43 to ventilate the indicator pipe 44 and the dust collection chamber 34. .

Further, 51 is a window frame for closing the upper part of the indicator pipe 44 of the lid 35, a transparent window 52 for viewing the operation of the indicator 45, and an indicator pipe 44.
It has an air intake port 53 for guiding air to. In front of the window frame 51 is a handle 54 for lifting the cleaner body 31.

The air intake port 53 has a vertical rib 56 as shown in FIG.
, air intake port 53, and vertical rib 56 are arranged in this order. Also, the vertical rib 5 on the side farther from the indicator pipe 44
6 extends below the vertical ribs 55, and horizontal ribs 57, 58 are provided on each of the vertical ribs 55, 56, so that the interior of the upper ribs cannot be seen. Also, 5
A filter 9 is provided to prevent dust, etc. that entered through the air intake port 53 from entering the indicator pipe 44 and having an adverse effect, and is supported by the window frame 51 and the lid 35.

In the above configuration, when dust accumulates in the paper bag 33 inside the dust collection chamber 34, the pressure inside the dust collection chamber 34 decreases. The indicator pipe 44 communicates with the inside of the dust collection chamber 34 via an indicator cylinder 49, and is in contact with the outside air pressure on the indicator 45 side. Therefore, when the pressure in the dust collection chamber 34 decreases, the indicator 46 starts to move toward the indicator elbow 49 against the force of the spring 46 due to the external pressure applied to the surface on the indicator lid 48 side. When the indicator 44 starts moving, air flows into the indicator pipe 44 through the gap provided between the indicator lid 48 and the indicator 44 and reaches the inside of the dust collection chamber 34.

This air enters from the air intake port 53 provided in the window frame 51, passes through the indicator hole 47 of the indicator lid 48, and is guided into the interior of the indicator pipe 44.

In this way, the air necessary to fully operate the indicator 45 is taken in from the air intake port 1o vane 53 provided in the window frame 51, and the structure of this part is as shown in FIG. , vertical rib 55, air intake port 5
3. Although the vertical ribs 56 are arranged in a grid pattern in order, the vertical ribs 56 are located on the side farther from the indicator pipe 44.
extends downward longer than the vertical rib 55, and the horizontal rib 57
A horizontal rib 58 is also provided at the bottom. Therefore, five dimensions can be provided in the vertical direction to ensure the air passage area necessary for operating the indicator 45, and the horizontal dimension related to air intake is the air intake port 53, vertical dimension. The air intake port 53 can be formed only by the total dimension C of the rib 55, the air intake port 53, and the vertical rib 56. In other words, it can be formed using only the total dimensions of the horizontal ribs 57, vertical ribs 55, horizontal ribs 58, and vertical ribs 56, which are provided so that the inside cannot be seen from above. Therefore, the lateral dimension of the window frame 51 can be made smaller than before, and miniaturization is possible. In this embodiment, the surface area of the window frame 51 necessary for air intake can be reduced, and the transparent window 52 through which the operation of the indicator 11 on page 45 can be seen can be enlarged, so that the operation of the indicator 45 can be easily seen by the user. ,
This improves usability.

Further, since the dimensions of the air intake port 53 and the vertical ribs 55 can be reduced, various processes can be easily performed in terms of design.

Further, as can be seen from the arrows shown in FIG. 5, according to this structure, the air flowing through the air intake port 53 is transferred to the horizontal rib 57.
It is possible to enter the window frame 51 by just hitting the window 58 once, and it becomes possible to obtain a smooth flow of wind, and the operation of the indicator 45 becomes smooth.

In addition, since the air entering from the air intake port 53 on the indicator pipe 44 side is vertically shifted, it does not collide with the air entering from the adjacent air intake port 53, and passes through the filter 59 and flows into the indicator pipe 44. flows smoothly into. Therefore, this also has the effect of improving the operation of the indicator 45 and eliminating hysteresis.

As described above, according to one embodiment of the present invention, the area of the window frame 51 can be reduced, making it possible to downsize the window frame 51, and the indicator 45 can have a smooth air flow. This has the effect of making the operation more accurate.

Effects of the Invention As described above, according to the present invention, the vertical ribs that fit in the air intake port and the vertical rib on the side farther from the indicator extend downward from the front vertical rib to provide an air passage. This has the advantage of reducing the size of the window frame and ensuring reliable indicator operation.
