Description

Detailed Description of the Invention 3. Detailed Description of the Invention Field of Industrial Application The present invention relates to a vacuum cleaner having a suction port cover for opening and closing the suction port.

BACKGROUND ART Conventionally, this type of vacuum cleaner generally had the following configuration. The configuration will be described below with reference to the drawings.

In Figures 5 to 7, 1 is an electric blower 2 and a dust collection chamber 3.
A paper bag 4 for collecting dust is removably attached to the dust collecting chamber 3. The dust collection chamber 3 is provided with an opening through which the paper bag 4 can be attached and removed, and a lid 5 for opening and closing this opening is rotatably provided on the cleaner body 1.

The lid body 6 was provided with a suction port 6 into which a hose was removably inserted, and a suction port cover 7 for opening and closing the suction port 6 was slidably provided.

In addition, as shown in FIG. 6, the suction port cover 7 has a rectangular shape with one end surface of the suction port cover 7 that slides on the suction port θ being in a straight line, and the central portion of the suction port cover 7 as shown in FIG. It was formed into a roughly circular shape with a protruding front part.

Problems to be Solved by the Invention In such conventional vacuum cleaners, when the suction port cover 7 is opened and closed after the dust adhering to the inside of the hose falls onto the suction port 6 when the hose is attached or removed, The dust that has fallen onto the suction port θ is pushed in the direction of sliding the suction port cover 7 or in the direction of the outer circumference of the suction port 6, as shown by the arrows in FIGS. It was gradually accumulating in my local area.

Therefore, when handling the area around the suction port 6, there is a problem that the user's hands get dirty and the user feels uncomfortable.

Further, dust accumulated on the suction port 6 gets caught between the suction port 6 and the suction port cover 7 when the suction port cover 7 slides, and
There was also a problem that the opening/closing operability of the suction port cover 7 deteriorated.

Means for Solving the Problems The present invention solves the above problems by recessing the central part of the front end surface of the slidable suction locoper that opens and closes the suction port in the sliding direction relative to its outer edge. It was formed by

According to the above structure, when the suction port cover is slid to close the suction port, the slope provided on the front end surface of the suction port cover causes the dust spilled around the suction port to be swept to the center of the suction port. Since the dust is collected in the paper bag through the suction port, the area around the suction port can be kept clean.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings. In Figures 1 to 4, reference numeral 8 denotes a vacuum cleaner body with a built-in electric blower 9 for suction and a dust collection chamber 10.
A paper bag 11 for collecting dust is detachably attached to the inside of the bag. Reference numeral 12 denotes a lid body that opens and closes the opening when attaching and detaching the paper bag 11, which is rotatably supported by the vacuum cleaner main body 8, and includes a gasket 13 that performs air tightness with the paper bag 11, and a suction port 14 to which a hose is attached. A slidable suction port cover 15 that opens and closes the suction port 14 is provided. 16 is a support plate that supports the paper bag 11. Further, as shown in FIG. 1, the suction port cover 15 is recessed at the center of its front end face, and is inclined rearward from the left and right outer edges toward the center.

To explain the operation in the above configuration, when the hose is attached to and detached from the suction port 14 before and after cleaning, especially when the hose is detached after cleaning, the dust adhering to the inside of the hose is caused by vibrations and shocks generated at the time of attachment and detachment to the suction port 14. However, after cleaning is finished and the hose is removed, if the suction port cover 16 is slid forward to close the suction port 14, the suction port 14 will become dirty as shown in FIG. Due to the slope provided on the front end surface of the mouth cover 15, dust spilled around the suction port 14 is removed from the suction port 14 as shown by the arrow.
The paper bag 1 below the suction port 14 is pressed into the center of the paper bag 1.
1 and collected, the area around the suction port 14 is always kept clean, preventing the user's hands from getting dirty or causing discomfort, and preventing the suction port cover 16 from getting caught in dust. Can prevent opening/closing defects.

FIG. 4 shows another embodiment of the present invention, in which the indentation toward the center of the front end face of the suction port cover 15 is formed in an arc shape, and the inclination from the outer edge to the center is changed. However, the same effect as in the above embodiment can be obtained. As shown in other embodiments of the present invention, even if the inclination of the end face from the outer edge to the center changes, the point is that if the center is recessed backward from the outer edge, the above-mentioned effect can be achieved. It is effective.

Effects of the Invention As is clear from the above-mentioned embodiments, the vacuum cleaner of the present invention has the central part of the front end surface of the suction port cover that opens and closes the suction port to which the hose is attached and detached recessed backward from the outer edge thereof. This creates a wiping effect when the suction port cover is opened and closed, and the dust spilled around the suction port is pushed toward the center by the slanted end surface toward the center and collected in the paper bag. As a result, the area around the suction port can be kept clean at all times so that the user does not feel uncomfortable, and it is possible to prevent the suction port cover from opening or closing incorrectly due to dust being trapped.
