Description

  The present invention relates to an electric vacuum cleaner, and more particularly to an electric vacuum cleaner having a structure having a rotating lid and a carrying handle for rotatably covering a dust collection chamber.

A conventional vacuum cleaner includes a vacuum cleaner main body case having a dust collection chamber at the front and an electric blower storage chamber at the rear, and a rotary lid that is rotatably attached to the vacuum cleaner main body case and covers the upper side of the dust collection chamber. And a cover that forms an electronic component storage chamber between the upper surface of the vacuum cleaner main body case, and a rotary support shaft formed integrally with the rotary lid is rotatably held between the cleaning main body case and the cover. The structure made to do is disclosed (for example, refer patent document 1).
JP-A-6-70866 (paragraph number 0014 on the third page, FIG. 1)

  Such a conventional vacuum cleaner has a structure in which the rotating support shaft of the rotating lid is rotatably sandwiched between the vacuum cleaner body case and the cover, so that the position of the rotating support shaft of the rotating lid is the electric vacuum cleaner. It is necessary to enter inside the basic appearance line of the machine body (that is, the outer shape line connecting the outermost surface of the rotating lid and the outermost surface of the cover) BL, and the locus of the rear end portion of the rotating lid is at the front end of the cover. For this reason, since it is necessary to provide a clearance to avoid interference with the cover when the rotating lid is rotated, the rotation is a clearance between the rotating lid and the cover formed so as to cross the vacuum cleaner body. There was a problem that the secant line had to be wide.

In addition, when the rotation support shaft of the rotating lid is rotatably held between the vacuum cleaner body case and the cover, the receiving side of the rotation support shaft is configured by combining the upper and lower parts of the cleaner body case and the cover. There is a disadvantage that the strength is weak, and in order to increase the strength, the vacuum cleaner main body case may have a structure in which the receiving side of the rotating support shaft is integrally formed.
However, even with the structure in which the receiving side of the rotating support shaft is integrally formed with the cleaner body case as described above, the position of the rotating support shaft of the rotating lid is based on the basic appearance line of the vacuum cleaner body. Inevitably, the width of the rotation secant had to be wide.
Also, when the vacuum cleaner body case has a structure that integrally forms the receiving side of the rotating spindle, the assembly work is performed to bend and fit either the rotating lid or the cleaner body case during assembly. Even if the lid is removed for maintenance or the like, it is difficult to remove the lid because the fitting is released by bending either the cleaner body case or the rotating lid.

Also, in any of the above conventional examples, the rotating bearing side is not used due to misuse such as applying an excessive force to the opened rotating lid or dropping the vacuum cleaner body from the stairs. When it is damaged, it is necessary to replace the vacuum cleaner main body case, which causes a problem that repair work and parts costs increase.
Therefore, in view of the above points, the present invention has an object to provide a vacuum cleaner having an improved appearance of a vacuum cleaner body and an improved assemblability and maintainability.

  The vacuum cleaner according to the present invention has a built-in electric blower in the main body of the vacuum cleaner, a dust collection chamber that sucks dust in the front of the main body of the vacuum cleaner, and a rotatable circuit at the top of the dust collection chamber. In a vacuum cleaner provided with a moving lid and provided with a carrying handle at a substantially central upper portion of the main body of the vacuum cleaner, the pivotal support shafts provided at the left and right end portions of the rotating lid are connected to the left and right ends of the carrying handle. It is rotatably supported by a bearing portion formed at a position above the basic appearance line of the main body of the vacuum cleaner inside the portion.

  As described above, according to the present invention, the rotary support shafts provided at the left and right end portions of the rotary lid are disposed at the substantially central portion of the vacuum cleaner body inside the left and right end portions of the carrying handle. The pivoting support shaft of the rotating lid is positioned above the basic external appearance line of the vacuum cleaner main body by being rotatably supported by the bearing portion formed above the basic external appearance line of the main body. Thus, the locus of the rear end portion of the rotating lid when rotating the rotating lid is in a direction away from the rear end portion of the rotating lid, for example, the front end portion of the upper case cover. The width space of the rotation dividing line composed of the rear end part of the moving lid and the front end part of the upper case cover can be reduced, and dust and the like enter the vacuum cleaner body from the small width space of the rotation dividing line. The appearance design of the vacuum cleaner body is improved. Door can be.

The electric blower built in the vacuum cleaner body 1 generates a negative pressure in the dust collection chamber 10 in the vacuum cleaner body 1 to suck dust from the suction tool 6, and separates dust and wind by a cyclone structure or a filter. The dust is collected in the dust collecting chamber 10 and the exhaust gas passes through the exhaust filter 12 and is discharged from the exhaust port.
Then, after the cleaning is completed, the basic operation of the electric vacuum cleaner is to throw away the dust accumulated in the dust collection chamber 10 by rotating the rotary lid 11.

Thus, when the rotating lid 11 is rotated in order to throw away the dust in the dust collecting chamber 10, the rotating support shaft 16 of the rotating lid 11 is located above the basic appearance line BL of the vacuum cleaner body 1. Therefore, the locus L drawn by the rear end portion 11a of the rotating lid 11 draws a circle away from the front end portion 13a of the upper case cover 13 as shown in FIG.
