BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical vacuum cleaner.

[0002]

2. Description of the Related Art Conventionally, as shown in the microfilm of Japanese Utility Model Laid-Open No. 58-177059, in a vertical vacuum cleaner, the dividing line between the dust collecting chamber lid and the motor chamber lid is located above the top surface of the nozzle portion. It was provided. This is because the dust collection chamber cover is opened / closed by rotating the foremost part of the dividing line as the center of rotation. When the dividing line is provided below the top surface of the nozzle part, the dust collection chamber cover is opened / closed. At this time, the front part of the dust collecting chamber lid was sometimes caught behind the central part of the nozzle part and could not be opened or closed.

[0003]

SUMMARY OF THE INVENTION With such a configuration,
In order to increase the dust collection volume, either the upper end of the dust collection chamber lid should be placed higher or the foremost part of the dust collection chamber lid should be placed further forward, but in the former case, the main body becomes large and the weight is heavy. However, in the latter case, when cleaning the bottom of the bed, the front part of the dust collection chamber cover is caught and does not get under the bed. .

Therefore, an object of the present invention is to obtain an electric vacuum cleaner having a larger dust collecting volume without increasing the height of the main body and the thickness direction of the front and rear.

[0005]

In order to achieve the above object, the present invention provides a dividing line between the dust collecting chamber lid and the motor chamber lid when the nozzle portion is fixed at a substantially right angle to the main body. Is provided below the top surface of the nozzle portion, the lowermost front portion of the dust collection chamber lid is provided above the rotation center of the dust collection chamber lid, and the dust collection chamber lid is provided from the rotation center of the dust collection chamber lid. The distance to the lowermost front portion is set longer than the distance from the center of rotation of the dust collection chamber lid to the central uppermost portion of the nozzle portion.

Further, the shape from the rotation center of the dust collecting chamber lid to the lower portion of the dust collecting chamber lid is provided in a concave shape with respect to the central uppermost portion of the nozzle portion.

[0007]

With the above construction, the dust collection volume can be increased as the dust collection chamber lid is enlarged. In addition, when opening and closing the dust collection chamber lid in this configuration, the distance from the rotation center of the dust collection chamber lid to the lowermost front portion of the dust collection chamber lid is from the rotation center of the dust collection chamber lid to the central uppermost portion of the nozzle portion. Since it is longer than the distance to the dust collection chamber lid, the dust collection chamber lid is not the front surface of the dust collection chamber lid, but the part from the center of rotation to the lowermost front portion of the dust collection chamber lid always hits the center uppermost portion of the nozzle portion. There is no reason that you cannot open and close it by being caught in the center rear.

Further, the shape from the rotation center of the dust collecting chamber lid to the lower portion of the dust collecting chamber lid is provided in a concave shape with respect to the central uppermost portion of the nozzle portion, so that when the dust collecting chamber lid is opened and closed, this concave portion is formed. Since the shape always hits the central uppermost part of the nozzle portion, not only the opening and closing angle of the dust collecting chamber lid is wide, which facilitates opening and closing, but also this concave shape invites the attachment and detachment of the dust collecting chamber lid.

Further, as shown in FIG. 2, the distance D1 from the rotation center 11 of the dust collection chamber lid 5 to the lowermost front portion 8 of the dust collection chamber lid 5 is from the rotation center 11 of the dust collection chamber lid 5 to the nozzle portion 6. It is provided so that D1> D2 with respect to the distance D2 to the central uppermost portion 9.

With the above structure, the dividing line between the dust collection chamber lid 5 and the motor chamber lid 4 is provided below the top surface of the nozzle portion 6, and the dust collection volume is increased as the dust collection chamber lid 5 is enlarged. Can be large. Further, when the dust collection chamber lid 5 in this configuration is opened and closed, the distance D1 from the rotation center 11 of the dust collection chamber lid 5 to the lowermost front portion 8 of the dust collection chamber lid 5 is the rotation center of the dust collection chamber lid 5. Since it is provided longer than the distance D2 from the central uppermost portion 9 of the nozzle portion 6 to the nozzle portion 6, the portion from the rotation center 11 to the lowermost front portion 8 of the dust collecting chamber lid 5 is not the front surface of the dust collecting chamber lid 5. As shown in FIG. 3, since the dust collection chamber lid 5 always hits the central uppermost portion 9 of the nozzle portion 6, there is no possibility that the dust collection chamber lid 5 is caught behind the central portion of the nozzle portion 6 and cannot be opened and closed.

Further, the shape from the rotation center 11 of the dust collecting chamber lid 5 to the lowermost front portion 8 of the dust collecting chamber lid 5 is the nozzle portion 6.
The concave shape 12 is provided with respect to the central uppermost portion 9.

With this structure, when the dust collecting chamber lid 5 is opened and closed, the concave shape 12 always hits the central uppermost portion 9 of the nozzle portion 6, so that the dust collecting chamber lid 5 can be opened and closed at an angle as shown in FIG. Not only makes it easier to open and close, but also
The concave shape 12 also serves as an invitation to attach and detach the dust collecting chamber lid 5.

[0013]

As described above, in the electric vacuum cleaner of the present invention, when the nozzle portion is fixed at a right angle to the main body, the dividing line between the dust collecting chamber lid and the motor chamber lid is set to the top surface of the nozzle portion. The lowermost front portion of the dust collection chamber lid is provided above the rotation center of the dust collection chamber lid, and the distance from the rotation center of the dust collection chamber lid to the lowermost front portion of the dust collection chamber lid.
