Description

Description A WASHER / DRYER
[001] This invention relates to a washer / dryer comprising a drum wherein one or more than one lifter is formed at its internal surface.
[002] Washer/dryers comprise a drum which incorporates several lifters at various dimensions in order to increase the washing efficiency by enabling the movement of the laundry placed inside the drum. Laundry is washed by the rotation of drum, from right to left and from left to right. During the washing process, by means of the lifters inside the drum, it is enabled that clothes are raised to a certain height and then left free to fall.
[003] In the current state of the art, the drum (103) inside a washer / dryer (101) is produced by joining the two opposite sides of a quadrangular plate by bringing them together and by combining the said plate with a front and rear lid. The lifters (104) are manufactured by shaping the mentioned plate that forms the drum (103) via employing such methods as cutting, boring and bending. The lifter (104) that is formed by employing the said methods is produced by utilizing the entire width of the plate and that reduces the strength of the drum (103) and the lifter (104) against various forces acting on them (Figure 1 and Figure 2).
[004] Additionally, in the current state of the art, there are also applications wherein the lifter (104) is attached to the drum (103) subsequently. In these applications, holes are constituted on the drum (103) or on the plate forming the drum (103) and by inserting one or more than one locking piece (105) on the lifter (104) from the internal surface of the drum (103) to the external surface, it is provided that the lifter (104) is attached and fixed to the interior of the drum (103). However, the mentioned locking piece (105) whereby the lifter (104) is attached to the drum (103), causes the distance between the tub (102) and the drum (103) to decrease by forming an undesired projection, from the external surface of the drum (103) towards the tub (102) (Figure 3 and Figure 4).
[005] The object of the present invention is the realization of a washer / dryer comprising a drum with an increased strength against various forces acting on it, wherein one or more than one lifter is mounted onto the said drum without decreasing its distance from the tub.
[006] The washer / dryer designed to fulfill the objective of the present invention is illustrated in the attached figures where:
[007] Fig.1 - is a side view of a drum in the current state of the art, with lifters positioned on it.
[008] Fig.2 - is a perspective view of a drum in the current state of the art, with lifters positioned on it. [009] Fig.3 - is a schematic view of a drum in the current state of the art, wherein lifters are attached to the said drum subsequently. [010] Fig.4 - is a schematic view of a washer / dryer in the current state of the art, comprising a drum wherein lifters are attached to the said drum subsequently. [011] Fig.5 - is a side view of a drum wherein indentations functioning as a lifter are formed on the said drum by utilizing deep drawing method . [012] Fig.6 - is a perspective view of a drum wherein indentations functioning as a lifter are formed on the said drum by utilizing deep drawing method . [013] Fig.7 - is a schematic view of a washer / dryer comprising a drum with indentations whereby the lifters are attached to the said drum. [014] Parts shown in figures are numbered as follows: 1. Washer/dryer 2. Tub 3. Drum 4. Indentation 5. Locking piece
[015] The washer / dryer (1) according to the present invention comprises a tub (2) and, a drum (3) located in the tub (2), in which the laundry is placed and which is produced via bringing together and joining the two opposite sides of a quadrangular plate. The drum (3) comprises one or more than one indentation (4) which is formed on the mentioned plate towards the interior of the drum (3) by utilizing deep drawing technique after or before the two opposite sides of the plate are joined together and, provides the motion of the laundry inside the drum (3) during the washing / drying process, wherein the length of the indentation is smaller than the width of the mentioned plate (Figure 5 and Figure 6).
[016] In the preferred embodiment of the present invention, the indentation (4) is in such a form that its depth increases towards the interior of the drum (3) wherein thanks to its form and size suitable for functioning as a lifter, it is achieved that the laundry is moved during the washing / drying process. Thus, via utilizing deep drawing method on the drum (3) or on the plate forming the drum (3), by indenting not the entire width of the plate but only a portion with a desired width, it is achieved to produce a drum (3) comprising one or more than one lifter with desired size and shape.
[017] As the indentation (4) may be applied onto the plate, it can be applied onto the drum (3) as well, after two opposite sides of the said plate are joined together. Various problems are experienced during the process of giving the desired shape to the drum (3), preferably circular, that is formed by joining the two opposite sides after the indentation functioning as a lifter is applied on the plate, and therefore shape faults may be observed. For that reason, in the preferred embodiment of the present invention, one or more than one indentation (4) functioning as a lifter is formed on the drum (3) by utilizing deep drawing method after two opposite sides of the plate are joined to produce the said drum (3).
[018] In the alternative embodiment of the present invention, the drum (3) comprises a lifter with one or more than one locking piece (5) and, one or more than one indentation (4) whereby the lifter is attached on the drum (3) subsequently by means of the mentioned locking piece (5).
[019] In the mentioned alternative embodiment of the present invention, in order to attach the lifter to the internal surface of the drum (3), an indentation (4) is formed on the plate at the location where the lifter is to be attached, towards the interior of the drum (3) by utilizing deep drawing method before or after two opposite sides of the said plate are joined together, wherein the size of the indentation (4) is not smaller than the size of the locking piece (5). The locking piece (5) fits into the mentioned indentation (4) and therefore, it is achieved that the lifter is mounted to the internal surface of the drum (3) without the formation of any undesired projection on the external surface of the drum (3) (Figure 7). Thereby, it is accomplished to produce a washer / dryer (1) comprising a drum (3) which comprises one or more than one indentation (4) formed by utilizing deep drawing method, whereby the lifters are attached onto the drum (3) without a formation of a projection on the said drum (3).
[020] By means of the present invention, it is achieved to manufacture a washer / dryer (1) comprising a drum (3) with an increased strength against various forces acting on it wherein one or more than one lifter is mounted onto the said dram (3) without decreasing its distance from the tub (2).
