Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to an improvement in the amount of dust collected by a vacuum cleaner and an improvement in the visibility of collected dust.

[0002]

2. Description of the Related Art A conventional vacuum cleaner has a configuration in which dust flowing from a suction port passes through an extension pipe / hose and is captured by a dust collection bag contained in a dust collection chamber of a main body. Therefore, when relatively large-volume dust such as paper waste enters the dust collection bag, the dust collection bag becomes full immediately, and there is a problem that the dust collection capacity cannot be obtained for the amount of dust collection. In addition, since the dust collection bag catches fine dust, the weight per unit area is large, and the dust inside the dust collection bag cannot be visually recognized, and the body constituting the dust collection chamber is opaque. There was a problem that it was difficult to understand whether only dust was collected. In addition, when a foreign substance or an unintended substance is sucked, there is a problem that recognition is difficult and it is difficult to take out.

An object of the present invention is to solve the above-mentioned problems and to provide a vacuum cleaner that can effectively use the volume of a dust bag and is easy to use.

[0004]

In order to achieve the above object, the present invention provides a dust collecting trap communicating with a dust collecting chamber containing a dust collecting bag and collecting dust at an upstream of the dust collecting chamber. By arranging and collecting dust before entering the dust collection bag and discarding it as necessary, the dust collection capacity of the dust collection bag can be effectively utilized.

[0005]

The invention according to claim 1 of the present invention comprises a suction means for sucking dust, and a dust collection chamber disposed in front of the suction means and containing a dust collection bag. A dust collection trap communicating with the chamber and collecting dust is arranged upstream of the dust collection chamber to capture dust before entering the dust collection bag and to effectively utilize the dust collection capacity of the dust collection bag. Can be.

[0006] The invention according to claim 2 of the present invention is to make the outer periphery of the dust trap transparent or translucent to check the amount of dust collection, and to remove foreign matter or unintentional substances. Thus, the user can easily recognize from outside.

According to a third aspect of the present invention, the dust collecting trap is provided with an openable / closable dust take-out lid, and dust trapped before entering the dust collecting bag is discarded as required. It is possible to do.

According to a fourth aspect of the present invention, in the dust collecting trap, the sucked air is swirled to separate the dust, and the dust is trapped by the accumulation of dust in the dust collecting trap. Reduce the decline in ability.

According to a fifth aspect of the present invention, there is provided a dust collecting channel switching means for switching a dust collecting channel.
The dust accumulated in the dust collection trap can be
The dust can be transferred into the dust collection bag and the dust can be discarded without soiling the hands, which is an advantage of the dust collection bag.

[0010]

(Embodiment 1) A first embodiment of the present invention will be described with reference to FIG. The same parts as those in the conventional example are denoted by the same reference numerals, and the description thereof is omitted.

A suction unit 3 is provided in the blower room 2 of the main body 1, and a dust collection room 5 is provided in front of the suction unit 3 in which a dust bag 4 is provided. A dust collecting volume 8 connected to the dust collecting chamber 5 via a connecting portion 7 on the upstream side of
A dust collecting trap 9 having

The operation of the above configuration will be described. Suction means 3
As a result, the dust that has flowed in with the airflow from the nozzle portion (not shown) flows into the dust collection trap 9 via the hose 10, is separated from the airflow in the dust collection trap 9, and is captured by the dust collection trap 9. You. The separated airflow passes through the dust collecting trap 9 together with the fine dust that cannot be separated, flows into the dust collecting chamber 5 through the connecting portion 7, and separates the fine dust by the dust collecting bag 4. After that, it passes through the suction means 3 and is discharged from the exhaust hole 11 of the main body 1.

With the above configuration, dust can be trapped by the dust trap 9 before entering the dust collection bag 4, and the dust collection capacity of the dust collection bag 4 can be effectively utilized.

An outer shell 12 forming the dust trap 9 is provided.
Is transparent or translucent, it is possible for the user to easily recognize the amount of collected dust and to easily recognize from outside when a foreign substance or an unintended substance is sucked.

Further, the lid 1 that can be opened and closed by the dust trap 9
By providing the dust collection bag 3, dust trapped before entering the dust collection bag 4 can be discarded as necessary, and the dust collection capacity of the dust collection bag 4 can be more effectively utilized. .

As shown in the drawing, the dust collecting trap 9 is constituted by a cyclone trap which separates dust by swirling an air flow, thereby lowering the suction capacity due to accumulation of dust in the dust collecting trap 9. Can be reduced.

(Embodiment 2) FIG. 2 shows a second embodiment of the present invention.
This will be described with reference to FIG. The same parts as those in the above embodiment are denoted by the same reference numerals, and the description thereof is omitted.

The configuration shown in FIG. 2 is an example of a flow path switching means in a cyclone trap configuration, and a communication pipe 14 for connecting a connecting portion 7 to the dust collecting chamber 5 and a dust collecting trap 9 is provided.
It is opened by a sub-communication opening 16 near the dust accumulation portion 15 and a main communication opening 17 of a cyclone trap configuration. The main communication opening 17 is provided with dust collection channel switching means 18 for opening and closing the opening.

With the above structure, the dust that has flowed in with the airflow from the nozzle portion by the suction means 3 flows into the dust collecting trap 9 via the hose 10. Then, FIG.
As shown in the figure, when the main communication opening 17 is open, the flow rate passing through the sub communication opening 16 decreases, and the flow velocity near the sub communication opening 16 decreases. Continue turning.

On the other hand, when the main communication opening 17 is closed as shown in FIG. 2B, the flow rate passing through the sub communication opening 16 increases, and the flow velocity near the sub communication opening 16 increases. The swirled dust flows into the communication pipe 14 from the sub-communication opening 16, flows into the dust collection chamber 5 via the connection portion 7, and is captured by the dust collection bag 4.

With the above configuration, the dust accumulated in the dust trap 9 is transferred into the dust bag 4 as necessary.
Dust can be discarded without soiling hands, which is an advantage of the dust collection bag 4.

Further, as the dust collection channel switching means 18,
In the cyclone trap configuration, a configuration in which the inflow angle is switched in the vicinity of the inflow portion to the dust trap 9, a means for switching swirling dust with an obstacle, a configuration in which the atmosphere and the inside of the dust trap 9 are bypassed, and the like are included. Alternatively, the inside of the dust trap 9 and the inside of the dust bag 4 in the dust collecting chamber 5 may be bypassed.
