no. 1 approach

[0031] figure 1 It is a schematic perspective view showing the appearance of a front-loading washing machine as an example of the washing machine according to the first embodiment of the present invention.

[0032] The above-mentioned drum-type washing machine includes an outer case 1 having an outer case opening 11 at the front. A door 2 for opening and closing an opening 11 of the outer case is attached to the front portion of the outer case 1 so as to be rotatable in the left-right direction by hinges. Moreover, the operation display part 12 is provided in the upper part of the front part of the outer case 1. As shown in FIG. The user selects a desired washing course by operating the operation display unit 12 . In addition, the operation display unit 12 displays, for example, the remaining time of the washing program and the like.

Abstract

The invention provides a washing machine, which includes a water supply spout (6) for supplying water into a rotating tank. The water supply nozzle (6) has: a nozzle main body (61), which is provided with a flow channel (L1) for water flow; and a rotating member (63), which is arranged on the flow channel L1 to generate swirling flow. The flow path (L1) has: a converging part (L2) arranged upstream compared with the rotating member (63); (63) It has a flow passage cross-sectional area larger than that of the constricted part (L2) compared to the arrangement upstream.

Description

technical field [0001] The invention relates to a washing machine. Background technique [0002] Conventionally, a washing machine having a water supply nozzle for supplying washing water in a drum is disclosed in Japanese translation of the International Application Specification, Japanese Translation, Japanese Patent Application Publication No. 2013-509281 (Patent Document 1). More specifically, the water supply nozzle sprays washing water, and a vortex is generated by the washing water. Thereby, the washing water is divided into fine parts, and the washing water is rapidly absorbed by the laundry. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: International Application Specification Japanese Translation Special Form No. 2013-509281 [0006] In addition, in the above-mentioned conventional washing machine, if the washing water sprayed from the water supply nozzle is powerfully sprayed onto the laundry, the washing water cannot be di...
