Electric cleaner

Abstract

An electric cleaner in which lowering of dust collection performance can be suppressed and maintainability can be enhanced. Air permeability of an air permeable material (131) at the innermost position of a bag body (122) is made higher than that of other air permeable materials (132, 133) to secure air permeability of the bag body (122) of a dust collection bag (19), and the thickness of the air permeable material (131) is made greater than those of other air permeable materials (132, 133) to cause dust collection capacity for dust sucked to be three-dimentionally increased in a thickness direction of the air permeable material (131). As a result, the air permeable material (131) is suppressed from being easily clogged, dust collection capacity of the dust collection bag (19) can be secured, lowering of dust collection performance by clogging of the dust collection bag (19) can be suppressed, and frequent replacement of the dust collection bag (19) is not necessary, which enhances maintainability.

Description

technical field [0001] The present invention relates to an electric vacuum cleaner including a first dust collecting part communicating with the suction side of the electric blower, and a second dust collecting part communicating with the downstream side of the first dust collecting part and the suction side of the electric blower, respectively. Background technique [0002] Conventionally, such an electric vacuum cleaner includes a vacuum cleaner main body in which an electric blower is accommodated. A hose body, an extension pipe, and a floor brush are sequentially connected to the suction side of the electric blower on the main body of the vacuum cleaner, and these hose bodies, extension pipes, and floor brushes form an air path that communicates with the suction side of the electric blower. A first dust collection unit for collecting coarse dust in the dust sucked in together with the air by the drive of the electric blower is provided on the wind path. In addition, the...

Problems solved by technology

[0006] Therefore, if the thickness of the air-permeable material located inside the dust bag is thin, the distance between the fibers is narrow, and when fine dust enters the dust bag, there is a problem that even a small amount will cause the mesh of the inner air-permeable material to clog, Dust hardly gets into the dustbag, making vacuuming impossible

[0007] On the other hand, if the air permeability of the inside air-permeable material is further increased, the air permeability of the outside air-permeable material is less than that of the inside air-permeable material, then the air-permeable material of the outside is blocked by fine dust, thereby reducing the air permeability of the air-permeable material. Significance of installing inside air permeable material

[0008] Moreover, since the dust bag is easily blocked in this way, the dust collection performance of the electric vacuum cleaner with the two-stage dust collection part is rapidly reduced. In addition, the dust bag must be replaced frequently, and there is a problem of reduced maintainability.
