The present invention relates to a household appliance comprising a lock.
In household appliances, the cover used for loading and unloading the items is enabled 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 cover into a lock disposed on the front wall of the body.
In the state of the art embodiment, the International Patent Application No. WO2012084483, a washer/dryer, comprising a lock group wherein the lock group is mounted on the front wall is explained.
Another state of the art embodiment is explained in the European Patent Application No. EP134448 In this application, a lock mechanism that is included in the electrical household appliance is disclosed.
In these state of the art embodiments, various additional stopper surfaces that are disposed on the body and that enable the rotational movement of the latch to be ended are required. These additional surfaces increase the production costs.
The aim of the present invention is the realization of a household appliance comprising a lock that provides ease of assembly and production, and furthermore decreases inventory costs.
In the household appliance realized in order to attain the aim of the present invention and explicated in the claims, a lock is realized, that comprises a stopper disposed on a pin that ends the rotation of a latch while a tenon is pushed into the lock and similarly ends the rotation of the latch in the reverse direction while the tenon is taken out of the lock.
In an embodiment of the present invention, the stopper enables the latch to remain in the locking position (C) and/or the free position (O) by bearing against the wall of the bearing. Thus, the stopper extending from over the pin enables the rotation of the latch to be ended by contacting the wall of the bearing during the rotation of the pin.
In an embodiment of the present invention, the stopper is integrated with the pin.
In an embodiment of the present invention, the stopper has at least one inclined surface. The surface of the stopper contacting the body at the locking position (C) and the surface of the stopper contacting the body at the free position (O) are not completely parallel to one another, having a certain limit angle therebetween predetermined by the producer. One of these surfaces is inclined with respect to the other. Thus, the surface that contacts the body during the rotation of the pin maintains this contact along the surface area.
In an embodiment of the present invention, the stopper extends from over the pin along the length of the bearing. Thus, the pressure applied by the stopper to the wall of the bearing continues all along the wall. Thus, the latch is kept in a more stable manner in the locking position (C) or the free position (O).
In an embodiment of the present invention, the latch is integrated with the pin.
In an embodiment of the present invention, the bearing is semicircular.
In an embodiment of the present invention, the lock comprises a circular recess arranged on the pin and a protrusion located on the bearing that is disposed almost all along the bearing and whereon the recess is seated.
In an embodiment of the present invention, the lock comprises two pins that are located on the latch and that extend in opposite directions on the same axis, and two bearings that are disposed on the body and that face one another, whereon the pins are seated. Thus, the stoppers disposed on each pin enable the latch to stay in a stable manner.
By means of the present invention, the production cost of the lock used in the household appliance is enabled to be decreased.

The household appliance (1) comprises
In the household appliance (1) of the present invention, the lock (9) comprises:
The tenon (5) located on the cover (4) is seated into the lock (9) that is disposed on the front wall (2) by pushing the cover (4). The tenon (5) that passes through the opening (3) arranged on the body (6) enables the latch (7) to rotate around the rotational axis (E) passing from the center of the pin (11) by pushing the latch (7) situated behind the opening (3). The latch (7) locks the tenon (5) inside the lock (9) during this rotation. The rotational movement of the latch (7) ends as the stopper (12) disposed on the pin (11) bears against the body (6) and the latch (7) remains stable in the locking position (C) by locking the tenon (5) inside the lock (9). As the cover (4) is pulled, the tenon (5) rotates the latch (7), whereto it is connected, in the reverse direction, this rotation of the latch (7) ends when the stopper (12) contacts the body (6) and thus the latch (7) remains stable in the free position (O) wherein the tenon (5) is outside the lock (9). The spring (8) remains at the right side of the rotational axis (E) in the locking position (C) and at the left side in the free position (O). The stopper (12), that enables the latch (7) to remain stable in the locking position (C) and the free position (O), being disposed on the pin (11) eliminates the requirement of forming an additional stopper (12) surface on the surface of the body (6). Consequently, the production costs are decreased and moreover different body (6) designs for different latch (7) designs are not required to be realized.
In an embodiment of the present invention, the stopper (12) enables the latch (7) to remain in the locking position (C) and/or the free position (O) by bearing against the wall of the bearing (10). Thus, the stopper (12) extending from over the pin (11) enables the rotation of the latch (7) to be ended by contacting the wall of the bearing (10) during the rotation of the pin (11).
In an embodiment of the present invention, the stopper (12) and the pin (11) are integrated as a single piece. Thus, ease of production is provided.
In an embodiment of the present invention, the stopper (12) has at least one inclined surface. The surface of the stopper (12) contacting the body (6) at the locking position (C) and the surface of the stopper (12) contacting the body (6) at the free position (O) are not completely parallel to one another, having a certain limit angle therebetween predetermined by the producer. One of these surfaces is inclined with respect to the other. Thus, the surface that contacts the body (6) during the rotation of the pin (11) maintains this contact along the surface area.
In an embodiment of the present invention, the stopper (12) extends from over the pin (11) in the direction of the length of the bearing (10). Thus, the pressure applied by the stopper (12) to the wall of the bearing (10) continues all along the wall. Thus, the latch (7) is kept in a more stable manner in the locking position (C) or the free position (O).
In an embodiment of the present invention, the stopper (12) and the pin (11) are integrated as a single piece. Thus, ease of production is provided.
In an embodiment of the present invention, the bearing (10) is U-shaped. Thus, the pin (11) situated on the latch (7) can be easily seated on the bearing (10) and the pin (11) can easily rotate on the wall of the bearing (10) around the rotational axis (E).
In an embodiment of the present invention, the lock (9) comprises a circular recess (13) arranged on the pin (11) and a protrusion (14) that is disposed on the bearing (10) almost all along the bearing (10) and whereon the recess (13) is seated.
In an embodiment of the present invention, the lock (9) comprises two pins (11) that are located on the latch (7) and that extend in opposite directions on the same axis, and two bearings (10) that are disposed on the body (6) and that face one another and whereon the pins (11) are seated. Thus, the stoppers (12) disposed on each pin (11) enable the latch (7) to remain in a stable manner.
In an embodiment of the present invention, the household appliance (1) is a washing machine.
In an embodiment of the present invention, the household appliance (1) is a laundry washer/dryer.
In an embodiment of the present invention, the household appliance (1) is a laundry dryer.
In an embodiment of the present invention, the household appliance (1) is a dishwasher.
By means of the present invention, a lock (9) is realized, the production cost and inventory cost of which are decreased and which is used in the household appliance (1).
