Embodiment Construction

[0023] Hereinafter, modes for implementing the present invention (hereinafter, referred to as “embodiments”) will be described in detail with reference to the drawings as appropriate. In the following, a washing machine capable of washing, rinsing, and dehydration (so-called fully automatic washing machine) will be described as an example, but it can also be applied to a washing machine capable of washing, rinsing, dehydration, and drying (so-called vertical washing and drying machine). ).

[0024] figure 1 It is a schematic diagram which shows the internal structure of the washing machine of this embodiment.

[0025] Such as figure 1 As shown, the washing machine 1 is configured to include a washing tub 2 , an agitating blade 3 provided at the bottom of the washing tub 2 , and a circulation channel R for circulating washing water in a substantially box-shaped steel plate outer frame (casing) 5 .

[0026] The washing tub 2 has a bottomed cylindrical shape and includes a mai...

Abstract

The present invention provides a washing machine capable of reducing the rigidity of the stirring blade and increasing the circulation water amount without excessively increasing the rotation speed. A plurality of back blades 33 extending in the radial direction are provided on the back surface side of the stirring blade 3, and the outer peripheral rib 35 and the inner peripheral ribs (36,37) extending in the circumferential direction and are spaced apart from each other in the radial direction. The tip 35a of the outer peripheral rib 35 located on the outer peripheral side of the stirring blade 3 is positioned on the lower surface 22a1 side of the height position Hm of the inlet 27 of the circulating water path R. The distal ends 36a and 37a of the inner peripheral ribs 36 and 37 positioned on the inner peripheral side with respect to the outer peripheral rib 35 are located farther from the bottom face (22a1) than the front end 35a of the outer peripheral rib 35.

Description

technical field [0001] The present invention relates to a washing machine provided with a circulation channel for circulating water in a washing tank. Background technique [0002] In the past, the following technical proposal has been proposed in the washing machine: a back blade extending radially is provided on the back side of a pulsator (stirring blade) arranged at the bottom of the washing tank, and a circulating water channel is provided on the side of the washing tank so that the pulsator By rotating, the water at the bottom of the washing tank is squeezed out to the circulation channel, thereby circulating the washing water. [0003] In addition, in order to improve washing performance, it is desired to increase the amount of circulating water. For example, it is proposed to increase the amount of water introduced between the back blades by removing the circumferential ribs (see Patent Document 1).
