Embodiment 1

[0057] figure 1 It is a side sectional view of a return type electric vacuum cleaner according to Embodiment 1 of the present invention, figure 2 yes means figure 1 The top sectional view of the general structure of the electric vacuum cleaner, image 3 yes figure 1 Side cutaway view of the basket of an electric vacuum cleaner.

[0058] The electric vacuum cleaner shown in these drawings has a motor chamber 3 with an electric blower 2 built in, a paper bag 4 disposed in front of the motor chamber 3, and a dust collection chamber 5 for storing the paper bag 4 in the interior of the vacuum cleaner main body 1, and the front end is connected to a The floor suction hose 6 etc. which are not shown in figure are comprised.

[0059] On the upper part of the vacuum cleaner main body 1, an upper cover 5a for opening and closing the dust collection chamber 5 and enabling easy replacement of the paper bag 4 is provided. Moreover, the front wheel 7 and the rear wheel 8 for moving th...

Embodiment 2

[0087] The following is based on the attached Figure 4 Example 2 will be described. Figure 4 It is a side sectional view of the return type electric vacuum cleaner of Example 2.

[0088] In Embodiment 2, as shown in the figure, the auxiliary rib 18 supporting the lower front part of the paper bag 4 in Embodiment 1 is made into a curved support wall 21 continuous with the curved support wall 16 forming the first shape maintaining member. In addition, in this second embodiment, the auxiliary ribs 22 in the front-rear direction are formed instead of the auxiliary ribs 18 below the upper cover 5 a in the first embodiment. In addition, the rear portion 22a of the auxiliary rib 22 functions as a second shape maintaining member instead of the auxiliary rib 18a in the first embodiment.

[0089] Also, other structures are the same as in Embodiment 1, in Figure 4 In , the same symbols are used for the parts that are common to Example 1.

[0090] Therefore, although Embodiment 2 d...

Embodiment 3

[0092] The following is based on Figure 5 Example 3 will be described. Figure 5 It is a side sectional view of the return type electric vacuum cleaner of Example 3.

[0093] Such as Figure 5 As shown, in Embodiment 3, the curved surface support wall 16 forming the first shape-maintaining member in Embodiment 1 is changed to the auxiliary rib 31 formed on the bottom surface of the basket 11, and the supporting rib 31 under the front part of the paper bag 4 in Embodiment 1 is omitted. Auxiliary ribs17. In this third embodiment, like the second embodiment, the auxiliary ribs 22 in the front and rear directions are formed instead of the auxiliary ribs 18 below the upper cover 5a in the first embodiment. In addition, the rear portion 22a of the auxiliary rib 22 functions as a second shape maintaining member instead of the auxiliary rib 18a in the first embodiment.

[0094] In addition, other structures are the same as in Embodiment 1, in Figure 5 In , the same symbols are ...

Abstract

The present invention provided a novel vacuum cleaner adopting a merit of a paper bag type vacuum cleaner excluding a point of economical efficiency and a merit of a cyclone type vacuum cleaner. This vacuum cleaner is provided with a motor chamber 3 incorporating an electric blower 2 and having a suction port 3a in its front, a paper bag 4 disposed in front of the motor chamber 3 and having a suction port 4a in its front, a dust collecting chamber 5 having a suction hose connecting port 9 in its front and capable of incorporating the paper bag 4 with the suction port of the paper bag communicated with the suction hose connecting port 9, and a rotational flow generating mechanism rotationally turning air including dust sucked in the paper bag 4 in the paper bag 4 and centrifugally separating the dust.

Description

technical field [0001] The present invention relates to electric vacuum cleaners, in particular to a novel electric vacuum cleaner which uses paper bags and separates dust from inhaled air on the principle of a cyclone. Background technique [0002] A general cyclone type electric vacuum cleaner is, for example, the vacuum cleaner shown in Japanese Patent Laid-Open No. 2002-17626. Compared with a disposable paper bag type electric vacuum cleaner, the dust storage part and the ventilation part are different, so that the odor of the gas is discharged. There is less, and the performance of the suction power drops less during use, and there is no need to discard the paper bag every time the dust is discarded. For economical reasons, the popularity of replacing the original paper bag-type electric vacuum cleaner tends to increase. However, such a cyclone type electric vacuum cleaner has a problem that dust is scattered and scattered when removing dust, which is not as good as a p...
