JP2504169Y2 - Vacuum cleaner - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a vacuum cleaner used at home.

<Prior Art> Conventionally, this type of vacuum cleaner is known, for example, from Japanese Patent Publication Nos. 63-31210 and 63-31211.

This conventional example is a vacuum cleaner that rotates a rotating brush by a driving wheel that rolls in contact with the floor surface and scrapes dust on the floor surface into the dust collection chamber of the suction case body by this rotating brush, even manually. It could be used even if a vacuum suction type vacuum cleaner was set on the connection pipe.

Further, the dust collection chamber is detachable from the suction case body, and the dust collection chamber is manually removed by removing the dust collection chamber from the suction case body.

<Problems to be solved by the invention> In this conventional vacuum cleaner, when a vacuum suction type vacuum cleaner is connected and used, the dust collected in the dust collection chamber is discarded in order to dispose of the dust. When I took the room out of the suction case body, I sometimes spilled the debris I had collected and tried to clean it again.

In addition, in order not to do so, when the trash was thrown away, the entire suction case was taken to the trash box and the trash was thrown away.

Moreover, when the dust collecting chamber is taken out from the suction case body, the hands are often soiled.

<Means for Solving Problems> The present invention focuses on this point, and installs a rotary brush driven by the driving wheel in the suction case body having a driving wheel that rolls in contact with the floor surface. In a vacuum cleaner in which dust on the floor surface is swept into a dust collecting chamber attached to the suction case body by a brush, a dust receiver having an L-shaped cross section which is rotated by a dust receiving shaft is provided in the dust collecting chamber. A receiving gear is attached to the dust receiving shaft, an operation gear corresponding to the receiving gear is fixed to one end of the operation lot, and an operation lever is attached to the other end of the operation lot, and the dust receiver is opened by the operation of the operation lever. The present invention relates to a vacuum cleaner.

<Operation> As is well known, when the suction case main body 1 is moved in the front-back direction in the state shown in FIG. 2, the rotation of the power train 5 rotates the transmission gear and the rotary brush 7 through the rotary gear 6 in the front-back direction, and the blade brush. 9 picks up dust on the floor such as tatami mats, jutan, and boards, and collects it in the dust collection chamber 12.

At this time, since the guide portion 23 is provided, the scraped dust is smoothly stored in the dust collection chamber 12 without scattering to the air inlet 21 side.

Then, in order to dispose of the dust collected in the dust collection chamber 12, the suction case body 1 is brought to the trash can, the dust receiver 14 is faced to the trash can, and the operation lever 20 is rotated to move the operation lever.
The position of the long hole of 20 is lowered and the operating lot 18 and the operating gear 17 rotate the receiving gear 16 against the spring 19, the dust receiver 14 opens on the bottom surface of the suction case body 1, and dust is thrown into the trash box.

<Embodiment> 1 is a box-shaped suction case body, which is composed of a lower case 2, an upper case 3, and a case lid 4.

The power vehicle 5 is slightly protruded from the bottom surface of the lower case 2 to the left and right of the center of the front and rear of the suction case body 1, and is attached to the shaft so that it cannot be changed vertically and horizontally.

The power vehicle 5 rotates back and forth due to frictional resistance due to contact with the floor surface, and a rotary gear 6 having an outer diameter slightly smaller than that of the power vehicle 5 is integrally fixed inside.

The rotary gear 6 engages with transmission gears (not shown) fixed to both ends of the rotary brush 7 to transmit the rotation of the power wheel 5 to the rotary brush 7.

The rotating brush 7 includes a brush mandrel 8 and the brush mandrel 8
Elastic force (rubber hardness) on the outer circumference with rubber or soft plastic
The blade brush 9 having a diameter of 50 to 60 degrees is radially and laterally twisted and planted, and is exposed from a dust collecting port 10 which is horizontally opened on the bottom surface of the lower case 2, and the outer dimension thereof is a power vehicle. The diameter is slightly larger or longer than 5.

At the tip of the blade brush 9, a plurality of horizontally long scraping protrusions 9'are provided in parallel to enhance the dust removing effect.

The case lid 4 is fixed to the upper case 3 by the left and right lid stoppers 11, and the gap between the outer periphery of the case lid 4 and the blade brush 9 is about 1 to 5 mm.

Reference numeral 12 denotes a dust collecting chamber formed on the rear side of the rotating brush 7, which is separated from the rotating brush 7 side by a partition wall 13 which is erected halfway, and a dust receiver 14 having an L-shaped cross section is provided on the bottom surface and the rear surface. The left and right dust receiving shafts 15 are rotatably provided.

A receiving gear 16 is fixed to one of the dust receiving shafts 15, and an operating gear 17 is provided corresponding to the receiving gear 16.

The operating gear 17 is attached to a D cut at one end of an L-shaped operating lot 18 fixed between the upper case 3 and the lower case 2 and rotates about the D cut as an axis.
It is always pushed upwards by 19.

The other end of the operation lot 18 is inserted into the elongated hole of the operation lever 20.

A vertically movable connection port 22 is provided in the rear of the center of the dust collection chamber 12 so as to connect the air inlet port 21 while narrowing it.

In order to allow dust sent from the rotating brush 7 to be smoothly thrown into the dust collecting chamber 12 in the front portion of the upper case 3, the gap between the rotating brush 7 and the dust collecting chamber 12 becomes wider as it approaches the dust collecting chamber 12. A guide 23 is provided.

The connection port 22 is hollow so as to be connected to an extension tube of a vacuum cleaner or a handle bar for a manual cleaner.

Reference numeral 24 is a rear driven vehicle provided below the lower case 2 and behind the motor vehicle 5.

Reference numeral 25 is a front driven wheel provided below the lower case 2 and in front of the motor vehicle 5 and the rotating brush 7.

26 is a band that covers the connection between the lower case 2 and the case lid 4.

Next, the operation will be described. As is well known, when the suction case body 1 is moved in the front-back direction in the state shown in FIG.
Rotation is transmitted via the rotary gear 6 and the rotary brush 7
The blade brush 9 picks up dust on the floor such as tatami mats, jutan, and boards, and collects it in the dust collection chamber 12 by rotating the blade in the front-back direction.

At this time, since the guide portion 23 is provided, the scraped dust is smoothly stored in the dust collection chamber 12 without scattering to the air inlet 21 side.

When a vacuum cleaner is connected, dust in the dust collection chamber 12 is sucked into the vacuum cleaner through the connection port 22.

At the time of this cleaning, when the floor surface is between the tatami mats or plates which are relatively flat as shown by the line D-D in FIG. 2, the rotary brush 7 rotates at the normal lowermost position.

Next, when the suction case body 1 has a sinker or a convex portion which sinks as shown by the line EE in FIG. 2 or when the front side is strongly pressed, the rotating brush 7 is repulsed by the elastic force of the blade brush 9. Then, as shown by the chain line F, the upper position is automatically changed to rotate.

In this way, the rotary brush 7 moves up and down automatically according to the floor surface state to remove dust without manual operation, and can be efficiently cleaned without the need for human judgment.

Of course, the automatic vertical movement of the rotary brush 7 moves up and down according to the unevenness even when the floor surface is continuously concave or convex, so that the cleaning can be performed more effectively.

To dispose of the dust collected in the dust collecting chamber 12, bring the suction case body 1 to the trash can, bring the dust receiver 14 toward the trash can, and rotate the operation lever 20 to rotate the operation lever 20.
The position of the long hole is lowered and the operating lot 18 and the operating gear 17 rotate the receiving gear 16 against the spring 19, the dust receiver 14 opens on the bottom surface of the suction case body 1, and the dust is thrown into the trash box.

<Effects of the Invention> The invention provides a suction case body having a driving wheel that rolls in contact with a floor surface, provided with a rotary brush driven by the driving wheel, and dust on the floor surface is sucked by the rotation brush. In a vacuum cleaner which is swept into a dust collecting chamber attached to a main body, a dust receiver having an L-shaped cross section which is rotated by a dust receiving shaft is provided in the dust collecting chamber, and a receiving gear is attached to the dust receiving shaft. The operation gear corresponding to the receiving gear is fixed to one end of the operation lot, and the operation lever is attached to the other end of the operation lot so that the dust receiver is opened by the operation of the operation lever. You can easily dispose of trash with one touch without getting dirty.
