Description

[Detailed explanation of the idea] This invention relates to a vacuum cleaner.

Horizontal vacuum cleaners often have a suction port at the front of the dust collection chamber and a filter at the rear of the dust collection chamber. The axis of the suction port is directly opposed to the dust collection surface of the filter, and the suction airflow is
Since the dust travels 25 meters toward the filter, the dust gets stuck in the filter and cannot be removed easily. There are some types of filters that have a compression plate that can move up and down to compress dust on the front of the filter, and use this movement to scrape off the dust attached to the filter with the edge of the compression plate. It is not possible to remove the dust because it is thrusting forcefully. Also, the noise caused by the wind blowing directly in front of the filter is large.

This idea was developed in view of the above points, and aims to provide a vacuum cleaner that can reduce filter clogging due to penetration of dust and reduce noise. .

This idea provides a dust collection chamber that is located at the front of the electric chamber containing the electric blower and communicates with the electric chamber, and a filter is housed vertically on the rear side of the electric chamber side of this dust collection chamber. A suction port is formed with a substantially horizontal axis at a position facing the upper part of the filter in the front part of the electric chamber, and the suction port is always urged upward into the dust collection chamber and along the front surface of the filter. a compression plate that moves up and down and is located above the opposing portion of the suction port and the filter when stopped;
This compression plate is characterized in that a compression surface that slopes smoothly downward toward the filter is formed. In other words, the air sucked in from the suction port is directed downward by the inclined compression surface of the compression plate, which reduces the noise caused by the air directly hitting the filter and prevents the filter from clogging. It is constructed so that the dust removal effect using the compression plate can be increased.

An embodiment of this invention will be explained based on the drawings.
Reference numeral 1 denotes a main body case in which an electric chamber 3 for housing an electric blower 2 is formed, and a dust case 4 is connected to this main body case 1 by a clamp 5. This dust case 4 has a bottom lid 5 that opens and closes from below.
A suction port 6 is formed at the upper part of the front surface with a substantially horizontal axis. Dust collection chamber 7 of dust case 4
A filter frame 10 housing a sponge filter 8 and a filter 9 formed by bending paper into a bellows shape is removably housed in the frame 10. On the front side of the filter frame 10, a filter frame 10 is arranged from the center toward the exhaust side as it goes downward. A net filter 11, which is a tilting filter, is attached. The front wall of the dust case 4 is also inclined in a direction that becomes farther away from the filter frame 10 as it goes downward from the suction port 6. That is, the dust collection chamber 7 is made to gradually become wider as it goes downward. A dust removal device 13 for removing dust from the filter 9 is rotatably attached to a support wall 12 on the exhaust side of the dust case 4.

A compression plate 14 is connected to the operation button 15 on the dust case 4 and is urged upwardly by a spring 16 so as to be movable up and down. The compressed surface 17 of the compressed plate 14 is connected to the net filter 1
It is sloped with an arc so that it smoothly goes downward as it approaches 1. Further, one end edge of the compression plate 14 is close enough to touch the net filter 11, and has a sliding surface 18 rising upward from the end edge.

In such a configuration, when the electric blower 2 is driven, outside air containing dust is sucked in from the suction port 6,
It is guided downward by the downwardly facing compression surface 17. Therefore, dust is less likely to penetrate the net filter 11. Furthermore, the dust accumulates as it is pushed downward by the wind pressure, and the volume of the dust collection chamber 7 increases as it goes downward, making it difficult for dust to fly up. Further, since the suction flow is guided by the arc-shaped compression surface 17, it turns as shown by the arrow and heads toward the net filter 11, and the dust 19 deposited below is also deposited from the direction away from the net filter 11.
Therefore, clogging of the net filter 11 is significantly alleviated. Further, by lowering the compression plate 14, the dust 19 is compressed, and at this time, the sliding surface 18 removes the dust from the net filter 11. However, since the dust does not stick to the net filter 11 forcefully, the dust can be easily removed. can do. Further, no noise is generated due to the suction air directly hitting the net filter 11, and the system is quiet.

Since this device is configured as described above, the slanted compression surface of the compression plate allows the suction air to be guided downward from the suction port without directly colliding with the filter. This has effects such as reducing impact noise, alleviating clogging of the filter, and easily removing dust from the filter using the compression plate.
