The opening 2 of the unit 1 is closed by a door 3 articulated in 4 to the unit 1.

La puerta 3 es del tipo ojo de buey y comprende un marco circular 31 y una parte interior 32, preferiblemente de cristal. La parte interior 32 comprende una parte central 33 con una parte convexa adyacente a dos partes cóncavas The door 3 is of the porthole type and comprises a circular frame 31 and an inner part 32, preferably of glass. The inner part 32 comprises a central part 33 with a convex part adjacent to two concave parts

34. Dicho con más precisión, la parte interior 32 de la puerta 3 está conformada de tal manera que la sección horizontal que pasa por el centro C de la puerta (figura 3) comprenda la parte convexa 33 dispuesta en el centro de la parte interior 32 y las partes cóncavas 34 adyacentes a la parte 33; las partes cóncavas 34 se unen en un lado con la parte convexa 33 y en el otro lado con una parte periférica circular 35 de la puerta 3. Dicha conformación de la parte interior 32 se estira verticalmente como mínimo la mitad de la altura H de la puerta 3. 34. More precisely said, the inner part 32 of the door 3 is shaped such that the horizontal section that passes through the center C of the door (figure 3) comprises the convex part 33 arranged in the center of the inner part 32 and the concave parts 34 adjacent to part 33; the concave parts 34 are joined on one side with the convex part 33 and on the other side with a circular peripheral part 35 of the door 3. Said conformation of the inner part 32 stretches vertically at least half of the height H of the door 3.

La parte convexa 33 tiene una extensión horizontal más baja que cada parte cóncava 34; las partes cóncavas 34 preferiblemente tienen la misma extensión horizontal. The convex part 33 has a lower horizontal extension than each concave part 34; the concave portions 34 preferably have the same horizontal extent.

La parte periférica circular 35 es adyacente a – y está integrada con - el marco 31. La parte periférica circular 35 tiene una forma idéntica a la de las puertas conocidas; de ese modo no es necesario cambiar la unión de la abertura de la lavadora que presiona contra la puerta 3 y, dicho con más precisión, con la parte periférica circular 35 de la puerta 3. De este modo, la puerta 3 se puede usar para cualquier tipo de lavadora de carga frontal. The circular peripheral part 35 is adjacent to - and is integrated with - the frame 31. The circular peripheral part 35 has an identical shape to that of the known doors; in this way it is not necessary to change the connection of the opening of the washing machine that presses against the door 3 and, more precisely, with the circular peripheral part 35 of the door 3. In this way, the door 3 can be used to Any type of front loading washer.

La parte interior 32 de la puerta está conformada simétricamente con respecto al eje vertical A que pasa a través del centro C de la puerta 3. La parte conversa 33 sobresale más allá del perfil interior P de la puerta de lo que lo hacen las partes cóncavas 34, es decir, tiene una profundidad mayor de las partes cóncavas 34 con respecto al perfil P en el lado de la puerta que, con la puerta cerrada, se ajustan dentro de la abertura 2. El perfil P es un eje vertical que pasa a través de la parte interior del marco 31 de la puerta P , es decir, la parte del marco 31 que presiona contra el panel frontal de la unidad 1 cuando la puerta 3 está cerrada. The inner part 32 of the door is symmetrically shaped with respect to the vertical axis A which passes through the center C of the door 3. The conversation part 33 protrudes beyond the inner profile P of the door than the concave parts do 34, that is to say, it has a greater depth of the concave parts 34 with respect to the profile P on the side of the door which, with the door closed, fit inside the opening 2. Profile P is a vertical axis that passes to through the inside of the frame 31 of the door P, that is, the part of the frame 31 that presses against the front panel of the unit 1 when the door 3 is closed.
