Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is particularly applicable to a vacuum cleaner, in which rope dust is wrapped in a coarse filter in a primary filter for capturing coarse harvests to reduce fine dust and eliminate clumping when the dust is released. The shape of the cover and the rib structure allow for smooth release of dust.

In conventional vacuum cleaners, dust-containing gas is sucked in from the suction port by a suction fan installed in the main body, and the dust is collected from outside the filter installed in the dust container, but When ejected, it creates dust and clumps, which causes discomfort to the user.

That is, when the dust is discharged from the filter in the dust container, the coarse and fine dust adhering to the filter falls, leaving the fine dust and causing discomfort to the user. The present invention solves the above-mentioned conventional problems and facilitates dust discharge.One embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes a vacuum cleaner with a built-in suction fan (not shown) attached via an elastic body, an exhaust port (not shown) on the rear surface, and a main body handle 2 on the outer upper surface. The partition wall 3 forming the front surface of the main body is provided with a large number of partition holes and a dust container receiving part la extending forward from the lower part of the partition wall 3.

Reference numeral 4 indicates a ring fixed to the exterior surface of the vacuum cleaner body 1, and reference numeral 6 indicates a dust container having flexible wheels 5 on the outer bottom surface, with the open rear surface 7 facing the partition wall 3 and the lower end placed in the dust container receiving part la. At the same time, it can be connected to the main body 1 using a buckle 5a.

A lid 9 having a suction port 8 to which a dust suction hose (not shown) is connected is attached to the front surface of the dust container 6 so as to be openable and closable. The lid 9 is pivoted on a hinge above the front end of the dust container 6, and is locked in the closed position by a locking means 11.

On the open side of the lid 9 of the dust container 6, there is a primary filter 13 which is made of a mesh-like material such as synthetic resin and has a substantially conical shape with a bottom, and has a plurality of ribs 12 extending in the vertical direction along its inner wall. is installed to capture coarse dust.

Behind the primary filter 3, there is provided a secondary filter 14, which is configured in a corrugated cylindrical shape using furnace materials such as furnace paper and furnace cloth, and which captures Hosoho, and has an appropriate space on its entire surface. It is surrounded by a partition wall 16 having an air inflow hole 15.
A pongee dust storage box IT is provided below the secondary filter 4 and is detachable from the main body 1 side of the dust container 6.

When the dust removal handle 18 is rotated manually or in conjunction with a cord reel, the secondary filter 14 rotates together with the dust removal handle 18, impacts a dust remover (not shown), and removes the dust by its vibration. They are being groomed to fall.
19 is a handle of the dust container, and 20' is a reinforcing part of the primary filter. In the above configuration, when the suction fan is started,
Dust-containing gas flows into the dust container 6 from the suction port 8 through a dust suction hose (not shown), and coarse dust is separated and captured by the primary filter 13 . The dust in the dust-containing gas that could not be separated by the primary filter 13 flows into the partition wall 16 through the air inlet hole 15 provided in the partition wall 16, and is separated by the secondary filter 14. The fine dust separated by the secondary filter 14 is deposited in a dust storage box 17 installed below the secondary filter 14.

Further, when the dust removal handle of the secondary filter 14 is rotated manually or in conjunction with the cord reel, the secondary filter 14 rotates and an impact is applied to the secondary filter 14 as described above, and the dust removal handle is rotated manually or in conjunction with the cord reel. The pongee dust adhering to the filter 14 is removed. The dropped fine dust is then deposited in the pongee dust storage box 17. The coarse dust trapped inside the primary filter 3 is released to the outside by opening the lid 9 provided at the front of the dust container 6, and the fine dust accumulated in the pongee dust storage box 17 is released from the dust container 6. After removing the dust storage box 1 from the main body 1,
7 from the dust container 6 and then discharged to the outside.

Since the pongee dust in the fine dust storage box 17 is separated from the primary filter 13 by the partition wall 16, when the coarse dust in the primary filter 13 is discharged and even if the dust container 6 is bent, It does not move to the primary filter side.

Generally, dust is thrown up when disposing of dust, and what causes discomfort to the user is coarse dust and woven dust, which are mixed together and thrown away together. This often occurs because when a part collapses, it disturbs the pongee dust and causes it to fly up.

In contrast, in this embodiment, the coarse dust and the woven dust are basically collected separately and disposed of separately, thereby avoiding the occurrence of a situation in which the coarse dust disturbs the pongee dust. Furthermore, in this embodiment, the primary filter 18 has a substantially conical shape with a bottom, but this is because the primary filter generally captures only coarse dust;
It allows textile dust to pass through, but when the coarse dust accumulates on the passing surface, the coarse dust acts as a secondary filter and captures the textile dust. Even if you separate the dust and dust and collect them in a bottle, they will still be taken into the primary filter, but by making the primary filter into a substantially conical shape, the dust will be shaped into a roughly conical shape, and fine particles will be drawn into the primary filter. The abundance is collected inside this area and prevented from coming out.

As a result, the pongee dust is encapsulated in roughly conical coarse dust, and even if the pongee dust accumulates, it will not be discarded. Furthermore, when the primary filter 13 is filled with dust, it is difficult for the dust inside the primary filter 3 to be released to the outside.
In this embodiment, since several ribs 12 are provided along the inner wall of the primary filter, the compressibility of the dust near the ribs is relaxed by the ribs 12, so that the dust is easily released. It has become. For example, when ribs are attached at four locations, the dust accumulated in the primary filter 13 is divided into four equal parts by the ribs 12. Therefore, the force with which dust tends to adhere to the inner wall of the primary filter is weakened to 1'4. In addition, since the primary filter 3 has a substantially conical shape with a bottom, even if the primary filter 3 is filled with dust, it is easily discharged to the outside. As described above, according to the present invention, when discharging the dust in the dust container, it is possible to discharge the dust without causing discomfort by reducing the amount of dust and rising up, and moreover, it is possible to discharge the dust without causing discomfort in the primary filter. In some cases, the dust in the primary filter can be smoothly discharged, and its industrial value is great.
