Abstract

This drum-type washing machine comprises: a rotating drum (43); a water tank (42); a motor (45); a filter case (83) having a built-in filter (65), the filter case communicating with the water tank (42) via a water drainage pipe (64) connected to a bottom part of the water tank (42); a circulation pump communicating with the filter case (83) via a circulating water intake pipe (68) connected to the filter case (83); a flow path (85) formed inward in a front part of the water tank (42), the flow path communicating with the circulation pump (67) via a circulating water discharge pipe (69) connected to the circulation pump (67); a plurality of jet ports (70) for discharging washing water into the water tank (42), the jet ports being provided to the inner peripheral side of the flow path (85); and a controller (81). The opening area of a jet port (70e) provided to the position farthest from a connecting part (69a) between the circulating water discharge pipe (69) and the flow path (85) is greater than the opening area of jet ports (70a, 70b) provided to the positions nearest the connecting part (69a).

Description

technical field [0001] The present invention relates to a drum type washing machine for washing laundry accommodated in a rotary drum. Background technique [0002] Conventionally, there has been proposed a drum-type washing machine in which washing performance is improved by spraying washing water on laundry (for example, refer to Patent Document 1). [0003] Next, use Figure 4 The structure of the conventional front-loading washing machine shown in Patent Document 1 will be described. [0004] Figure 4 It is a cross-sectional view of a conventional front-loading washing machine. [0005] Such as Figure 4 As shown, the conventional drum-type washing machine includes at least a drum 21, a water storage tank 23 as a water tank, a heater 36, and a circulation device. [0006] Drum 21 is installed in water storage tank 23 so that it can rotate freely in the horizontal direction. Further, on the front surface of water tank 23 , facing the opening of the front surface of dr...
