That is, a large amount of water can be supplied to the flow path L1 of the nozzle body 61.
  • the washing machine of one embodiment is A door 2 attached to the outer box 1 for opening and closing the outer box opening 11; When the door 2 closes the outer box opening 11, a part of the door 2 enters the rotating tub 4 and overlaps the water injection region of the water supply nozzle 6.

Abstract

L'invention concerne une machine à laver équipée d'une buse d'alimentation en eau (6) destinée à alimenter en eau l'intérieur d'un tambour rotatif. La buse d'alimentation en eau (6) comprend un corps de buse (61) doté d'un canal (L1) à travers lequel l'eau s'écoule, et un dispositif de tourbillonnement (63) qui est disposé dans le canal (L1) et génère un écoulement tourbillonnant. Le canal (L1) comprend une section étroite (L2) qui est prévue sur le côté amont du dispositif de tourbillonnement (63) et des sections larges (L3, L4) qui sont prévues sur le côté aval de la section étroite (L2) mais sur le côté amont du dispositif de tourbillonnement (63) et ont une plus grande aire en coupe transversale de canal que l'aire en coupe transversale de canal de la section étroite (L2).
