Problems solved by technology

Therefore, the transmission loss until the vibration of the vibrator 1112 is transmitted to the sheet body 1116 is large, resulting in vibration attenuation.
[0012] Therefore, in order to obtain sufficient dust removal performance by vibrating the sheet body 1116, it is necessary to increase the output of the vibration generating source, and it is unavoidable to increase the size of the vibrator 1112.

Abstract

Disclosed is an electric vacuum cleaner comprising an electric fan, a filter (40) for capturing the dust sucked in by the electric fan, and a dust removal unit (45) for removing dust that has adhered to the filter (40). The dust removal unit (45) has: a drive unit (54) which has a control unit (53) for linear operation and provides reciprocating drive,a dust removal element (55) which is arranged near the filter (40) and can essentially move in the same direction as the direction of the reciprocating drive of the drive unit (54),and an elastic unit (56) which transmits the reciprocating drive of the drive unit (54) to the dust removal element by way of an elastic body. The amplitude of the reciprocating drive of the dust removal element (55) is increased by resonance generated by the elastic unit (56) and causes the filter (40) to oscillate.

Description

technical field [0001] The present invention relates to an electric vacuum cleaner provided with a filter for filtering dust. Background technique [0002] Conventionally, as a method of preventing filter clogging in the field of electric vacuum cleaners, a method of vibrating a filter to remove dust has been proposed. For example, there has been proposed a vacuum cleaner including a dust removal unit in which a plurality of claws fitted into each pleat are vibrated in a filter having a plurality of pleats bent in a wave shape in cross-section (for example, refer to Patent Document 1). [0003] Figure 13 It is a schematic diagram which shows the schematic structure of the conventional electric vacuum cleaner 1000. Figure 14 It is a perspective view which shows the structure of the filter apparatus 1111 in the conventional electric vacuum cleaner 1000. [0004] Such as Figure 13 and Figure 14 As shown, electric vacuum cleaner 1000 includes: filter device 1111 that capt...
