## Background
The present invention relates to a washer/dryer that comprises a lock.
In washers/dryers, the lid used for loading and unloading the laundry is provided to be kept in the closed position by means of a lock. Locking is realized by the placement of a tenon generally disposed on the lid into a lock disposed on the front wall of the body.
In the state of the art, the members that form the lock are in grouped state. The lock group is realized by passing the lock port into which the tenon enters entirely to the front side from the rear side of the front wall, through an opening disposed on the front wall and by fixing the lock port in this position.
The fixation process is generally performed by means of screws and this causes an increase in terms of both the material cost and the labor cost. In the state of the art, various embodiments are developed related to the mounting of the lock group to the front wall without screws.
In the state of the art embodiment, the European Patent Application No. EP1681386, a washer/dryer comprising a lock group which is mounted onto the front wall in a telescopic manner by being rotated and slid after being inserted from one side is explained.
Another state of the art embodiment is explained in the German Patent Application No. DE38106476. The washer/dryer explained in this application has a body that is assembled by mounting the protrusions disposed on the base into the housings disposed on the side walls.
In these state of the art embodiments, the opening disposed on the front wall should be of the dimensions of the lock port. Any change in the configuration of the port requires the front wall also to be changed.
The aim of the present invention is the realization of a washer/dryer that can be easily mounted.
In the washer/dryer realized in order to attain the aim of the present invention and explicated in the claims, the lock comprises a body that remains at the rear side of the front wall. An extension, which extends towards the front of the front wall through the hole on the front wall, is disposed on the body. The lock is provided to be fixed to the front wall by means of a connection member mounted to the extension from the front of the front wall. When the lock is mounted to the front wall, the body remains behind the front wall and the connection member in front thereof. Thus, the lock is provided to be easily mounted to the front wall.
A port is disposed on the connection member and a housing, which is aligned with the port when the connection member is mounted onto the extension, is disposed on the extension. The tenon is placed into the lock by passing through the port and the housing.
In an embodiment of the present invention, the connection member is mounted by being slid by the placement of the slides disposed on the edges of the connection member into the rails disposed on the edges of the extension. In a variation of this embodiment, an inlet, which enables the slides to be inserted onto the rail, is provided at the lower end of the slides.
In an embodiment of the present invention, a detent means is disposed on the body. While the connection member is mounted onto the extension by being slid, the detent means is opened by being pushed by a pushing surface disposed on the body. When the sliding process is continued afterwards, the detent means leaps over the pushing surface and the detent means, which is disposed aligned with the recess, on the body just behind the pushing surface in the sliding direction, becomes free and is placed into the recess. After being placed into the recess, the detent means prevents the movement of the connection member by bearing against the recess walls.
In an embodiment of the present invention, the connection member is also wider than the hole and the extension so as to close the hole and the extension and hence to provide an aesthetic appearance at the side visible to the user.
In an embodiment of the present invention, the lock comprises a latch which provides locking and a spring that the latch compresses by its movement. The latch is rotatably mounted to the body and disposed behind the housing.
By means of the present invention, in the washer/dryer the lock is provided to be easily mounted to the front wall.
