Description

[Detailed explanation of the idea] The present invention relates to improvements in manual vacuum cleaners.

Conventionally, a manual vacuum cleaner as shown in FIG. 1 has been used. This manual vacuum cleaner has a rotary brush 2, a dust tray, and a rolling wheel 4 for giving rotation to the rotary brush 2 and supporting the machine case 1 on the floor on the lower surface of a flat machine case 1 with an open bottom. The machine box 1 has a long handle 5 on the top surface for operating the machine box.

However, in such a conventional example, the rotating brush 2
There was a problem that it was not possible to store small items such as a brush for removing lint etc. attached to the lint, making it inconvenient to use. Therefore, machine box 1
Although it is conceivable to form a small item storage section by recessing the top surface, since the rotating brush 2, dust tray, rolling wheels 4, etc. are arranged on the bottom surface of the machine box 1, it is possible to store small items with a large storage space. It is extremely difficult to form the part, and if it is forcibly formed, the outer diameter or axial length of the rotating brush will be limited and the dust removal function will be reduced. Therefore, the outer diameter and axial length of the rotating brush must be set to the desired size. If this is attempted, a problem will arise in which the machine box 1 becomes larger.

The present invention was developed in consideration of the above circumstances, and its purpose is to effectively utilize the space that exists in the front part of the machine box and above the rotating brush. The object of the present invention is to avoid the deterioration of the dust removal function due to the increase in the size of the rotary brush and the decrease in the size of the rotating brush, and to provide a small article storage section with a reasonably large storage space.

To achieve this objective, the present invention is constructed as follows. That is, a machine box with an open bottom surface, a rotary brush disposed at the front rear side of the machine box and rotatably supported with a small space between the side wall of the machine box, and the machine box. The top surface is open at the front and has a maximum depth that is approximately equal to the height of the machine box, a width that is equal to the axial length of the rotating brush, and a length in the front-rear direction that extends to the top along the outer periphery of the rotating brush. a removable cover that covers an opening of the small item storage section; a driven wheel disposed in the small space and fixed concentrically to the rotating brush;
A drive wheel is attached to the machine box in a swingable manner via an arm in front of the driven wheel, and contacts the floor and the driven wheel by moving the entire machine box forward to drive the driven wheel, and a rotating brush. a dust receiving box disposed at the rear of the machine box, the front part being pivotally supported on the side surface of the machine case, the rear part being detachably engaged with the machine case and attached to the machine case, and having a comb tooth part on the front edge; The dust receiving box is equipped with a wheel rotatably supported on the rear lower surface thereof.

In this way, there is a small space between the front and rear side of the box and the side wall of the box, and the space for the driven wheels, driving wheels, dust tray with comb teeth, etc. is secured. In other words, the space existing in the front of the machine box, which is the space in front of the rotating brush arranged with the desired outer diameter and axial length, and the space existing in the upper part of the rotating brush can be effectively utilized. Since it is used to form a storage area for small items, it is possible to increase the size of the box and
It is possible to provide a small article storage section with a large storage space while avoiding deterioration in dust removal function due to downsizing of the rotating brush.

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 2 to 4. FIG. 2 is a back view of the manual vacuum cleaner, and 10 is a machine case. This box 10 has a container shape with an open bottom and is made of synthetic resin. The direction of arrow A is the front of the box 10.

A small article storage section 11 having a maximum depth approximately equal to the height of the machine case 10 is integrally provided in the front part of the machine box 10.
is formed with an open top surface. A cover 12 is removably provided over the opening of the accessory storage section 11. A rotary brush 13 is disposed at the rear lower side of the accessory storage section 11 in a state where it is rotatably supported by a shaft on the side wall of the box 10. A dust receiving box 14 is provided behind the rotating brush 13.
This dust box 14 has a pin 15 protruding from the front side.
It is rotatably supported on the machine case 10, and is attached with an engaging portion 16 formed at the rear part releasably engaged with the machine case 10. Also, dust box 1
A comb tooth portion 17 is provided on the front edge of the rotary brush 13 to remove dust attached to the rotating brush 13 and drop it into the dust receiving box 14. Further, a handle attachment portion 18 is attached to the upper surface side of the box 10 so as to be rotatable about a shaft 19.

The axial length of the rotating brush 13 and the accessory storage section 11
The width of the box 10 is set so that there is a small space between the box 10 and the side surface of the box 10. That is, the accessory storage section 1
1 is formed to have a maximum depth approximately equal to the height of the machine box 10, a length in the front-rear direction extending to the top of the rotating brush 13, and a width such that a small space exists between it and the side surface of the machine box 10. Because of this, a large storage space can be secured. A driven wheel 20 fixed concentrically with the rotating brush 13 is provided in this space. In front of the driven wheel 20, as shown in FIG. 4, a rubber drive wheel 22 is provided swingably via an arm 21. This drive wheel 22
protrudes from the lower surface of the machine case 10, moves rearward as the machine case 10 moves forward, is pressed against the driven wheel 20, and transmits the rotation of the drive wheel 22 to the driven wheel 20. Further, the arm 21 is attached to the machine box 10 via a bracket 23.
Furthermore, wheels 24 are provided on the rear lower surface of the dust receiving box 14.
is rotatably mounted.

Such an embodiment has the following effects.
That is, since the machine box 10 is provided with the small item storage section 11 with a large storage space, this small object storage section 11 can store many small items such as cleaning brushes for the rotating brush 13 and hand tools, making it easy to use. It is convenient for inspection and maintenance. Moreover, Kibako 10
Since the rotating brush 13 can be set to a desired outer diameter and axial length without becoming large in size, the dust removal function is not degraded.
Further, the driven wheel 20 is driven by the drive wheel 22 to move the machine box 10.
The rotating brush 13 is driven only when moving forward.
Garbage can be dropped into a dust box 14 located behind the dust box 14.

As explained above, according to the present invention, it is possible to provide a manual vacuum cleaner in which a small article storage section for storing small articles is provided in the machine box, and furthermore, since a large storage space can be secured for the small article storage section, the rotary brush In addition to cleaning brushes, it can also easily accommodate hand tools such as screwdrivers, spanners, and wrenches, making it convenient for maintenance and inspection.This also avoids increasing the size of the machine box and reducing the ability to remove dust. Its practical effects are great.
