Thereby, the laundry Q in the washing tub 4 is agitated and washed by the rotating rotor 5. Further, the dirt of the laundry Q is decomposed by a detergent dissolved in water.

Therefore, even if the rotating wing 5 rotating during the washing process after the water supply process is intended to push the laundry Q in the washing tub 4 upward, the laundry in the washing tub 4 can be prevented by the laundry Q1 functioning as a lid.

In this state, the control unit 35 rotates the washing tub 4 at a low speed, for example, at 30 rpm, so that the shower is spread all over the corners of the laundry Q. Thereby, the laundry Q in the washing tub 4 is rinsed in all directions. After that, the control section 35 performs the same intermediate dehydration process as step S4 (step S6).

Abstract

L'invention porte sur un lave-linge à chargement par le haut pour empêcher que le linge soit expulsé, et ayant une capacité de réception de linge accrue. Le lave-linge à chargement par le haut (1) comprend : un cylindre de lavage (4) pourvu d'un orifice d'accès (21) dans un état constamment ouvert au niveau d'une extrémité supérieure de celui-ci; une nervure rotative (5) disposée au niveau d'une paroi inférieure (4B) à l'intérieur du cylindre de lavage (4); une buse d'alimentation en eau (12) faisant face à l'orifice d'accès (21); et une partie de commande (35). La partie de commande (35) exécute un procédé d'alimentation en eau. Le procédé d'alimentation en eau comprend : un traitement d'injection dans lequel de l'eau est pulvérisée, par l'intermédiaire d'une soupape d'alimentation en eau (13), à partir de la buse d'alimentation en eau (12) vers le linge (Q1) au niveau d'un côté orifice d'accès (21) à l'intérieur du cylindre de lavage (4); un traitement de rotation de cylindre dans lequel le cylindre de lavage (4) est mis en rotation par l'intermédiaire d'un moteur (6); et un traitement final dans lequel de l'eau est ajoutée au cylindre de lavage (4) par l'intermédiaire de la soupape d'alimentation en eau (13) après le traitement d'injection et le traitement de rotation de cylindre. Après le procédé d'alimentation en eau, la partie de commande (35) exécute le procédé de lavage suivant : faire tourner la nervure rotative (5) par l'intermédiaire du moteur (6) lorsque de l'eau est présente dans le cylindre de lavage (4), de façon à agiter le linge (Q) dans le cylindre de lavage (4).
