Definitions

  • the present invention relates to a laundry washer/dryer comprising a door which can be easily opened.
  • the laundry washer and/or dryers generally comprise a rotary drum wherein the laundry is loaded and which can be accessed through an access opening closed by a door.
  • An electric motor drives the rotary drum so as to tumble the laundry therein so as to be in mechanical interaction with each other and with the drum surfaces.
  • the door can only be opened when force is applied to rotate the latch holding the door.
  • the doors of the laundry washer and/or dryers should not be opened without applying a certain force. Every time the user wants to open the door, he/she has to apply said opening force to the door. Said force applied to open the door causes the door, the lock, the latch and other locking member to wear down in the course of time. Ultimately, the door and the locking member may deteriorate or even break after a while.
  • US7306266B2 discloses a latch mechanism for doors used on household appliances, and in particular a latch mechanism which tightens a door seal or similar component.
  • the aim of the present invention is the realization of a laundry washer and/or dryer comprising a door which can be opened/closed in an easy, quick and safe manner.
  • the laundry washer and/or dryer realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, is a laundry washing machine, a laundry dryer or a laundry washer and dryer, and comprises a body; a drum which is disposed in the body and wherein the laundry is loaded; an access opening which is provided on the body and which provides access into the drum; a door which is attached to the body by means of a hinge and which can move between an open position wherein the door provides access into the drum through the access opening and a closed position wherein the door closes the access opening; a locking member having a lock body which is provided on the body, a latch which is rotatably attached to the lock body, and a spring which is attached to the latch at one end and to the lock body at the other end; a locking hook having a first hook whereon a first locking housing is provided and a second hook whereon a second locking housing engaging with the latch when the door is in the closed position is provided; an actuation member which is provided on the door and which
  • the locking hook has a hook body and the first hook and the second hook which extend in directions opposite to each other over the hook body. While the door is being opened or closed, the hook is operated under a linear load in the pressing or pulling direction and by means of the first and second hooks extending in opposite directions from the hook body, the locking hook is prevented from being exposed to lateral loads and thus from bending. Thus, the economic life of the locking hook is increased.
  • first locking housing and the second locking housing are positioned at an equal distance from the hook body.
  • the first locking housing and the second locking housing are positioned at an equal distance from each other so as to extend in the same direction as the hook body.
  • the first hook and the second hook are formed so as to be mirror-symmetric.
  • the hook can be attached to the lock body from both sides, regardless of the mounting direction. Consequently, the hook is prevented from being incorrectly mounted.
  • an elastic member which compresses when the actuation member is moved and applies force to the actuation member towards its free position, is disposed between the actuation member and the door.
  • the actuation member automatically returns to its initial position thanks to the elastic member, providing ease of use.
  • a sliding surface extending at an angle with respect to the first hook is provided on the resting surface.
  • the sliding surface is positioned at an angle of 30 to 60 degrees with respect to the resting surface.
  • a handle suitable to be easily gripped by the user is provided on the door, and the actuation member is placed on the door so as to remain behind the handle.
  • the actuation member is hidden behind the handle and the external appearance is improved.
  • ease of access is provided by ensuring that the actuation member is positioned at the part where the user contacts on the door.
  • the door of the laundry washer and/or dryer is enabled to be opened/closed in an easy, quick and safe manner.
  • the laundry washer and/or dryer (1) comprises a body (2); a drum (3) which is disposed in the body (2) and wherein the laundry is loaded; an access opening (4) which is provided on the body (2) and which provides access into the drum (3); a door (5) which is attached to the body (2) by means of a hinge and which can move between an open position wherein the door (5) provides access into the drum (3) through the access opening (4) and a closed position wherein the door (5) closes the access opening (4); and a locking member (7) having a lock body (8) which is provided on the body (2), a latch (10) which is rotatably attached to the lock body (8), and a spring (9) which is attached to the latch (10) at one end and to the lock body (8) at the other end.
  • the door (5) is closed and the washing/drying process is performed. While the laundry washer and/or dryer (1) is in operation, the door (5) is locked and the laundry is enabled to remain in the drum (3) during the operation.
  • the lock body (8) provided on the body (2) and the latch (10) rotatably attached to the lock body (8) enable the door (5) to be fixed to the body (2).
  • the latch (10) can rotate and move between a lock position wherein the door (5) is locked and a free position wherein the door (5) is in the open position, and can move from the locked position back to the free position suitable for locking by means of the spring (9).
  • the laundry washer and/or dryer (1) of the present invention comprises a locking hook (11) having a first hook (13) whereon a first locking housing (14) is provided and a second hook (15) whereon a second locking housing (16) engaging with the latch (10) when the door (5) is in the closed position is provided; an actuation member (17) which is provided on the door (5) and which is suitable to be moved by the user; and a resting surface (18) which is provided on the actuation member (17), which is fitted into the first locking housing (14) so as to enable the locking hook (11) to be connected to the door (5) and which enables the locking hook (11) to be released from the first locking housing (14) and separated from the door (5) when the actuation member (17) is moved.
  • the actuation member (17) is configured to be slidably move on the door (5). While the door (5) is in the closed position, the actuation member (17) is moved so as to enable the locking hook (11) to be released from the resting surface (18). In this case, the door (5) is released from the locking hook (11) and becomes free. Thus, when the user wants to open the door(5), he/she can open the door (5) by simply sliding the actuation member (17), without having to pull the door (5) outward by applying a high force.
  • the locking hook (11) has a hook body (12) and the first hook (13) and the second hook (15) which extend in directions opposite to each other over the hook body (12).
  • the first hook (13) and the second hook (15) extend in the opposite direction to each other, on the same line.
  • the first locking housing (14) and the second locking housing (16) are positioned at an equal distance from the hook body (12).
  • the stress generated in the hook body (12) is distributed more evenly towards the first locking housing (14) and the second locking housing (16). Consequently, stress accumulation in the hook body (12) is prevented and the economic life of the locking hook (11) is increased.
  • first hook (13) and the second hook (15) have the same form.
  • the first hook (13) and the second hook (15) are configured to be mirror-symmetric.
  • the locking hook (11) can be mounted from both directions, regardless of direction.
  • the locking hook (11) can be mounted more easily and quickly.
  • an elastic member (21) which compresses when the actuation member (17) is moved and applies force to the actuation member (17) in a direction opposite to the movement direction, is disposed between the actuation member (17) and the door (5).
  • the elastic member (21) can be manufactured as a separate part or integrated with the actuation member (17). In this case, the actuation member (17) can return to its initial position with its own flexibility by resting directly on the door (5).
  • the elastic member (21) compression spring can also be manufactured from rubber or a plastic material with elastic properties.
  • a sliding surface (19) extending at an angle with respect to the first hook (13) is provided on the resting surface (18).
  • the sliding surface (19) is provided on the actuation member (17) so as to contact the first hook (13) when the door (5) is being closed.
  • the locking hook (11) remains on the body (2).
  • the first hook (13) bears against the sliding surface (19).
  • the inclined sliding surface (19) enables the actuation member (17) to move more easily and the first hook (13) is seated on the resting surface (18).
  • the door (5) is locked more quietly and securely.
  • the sliding surface (19) is positioned at an angle of 30 to 60 degrees with respect to the resting surface (18).
  • the door (5) can be closed with less force.
  • a handle (6) suitable to be easily gripped by the user is provided on the door (5), and the actuation member (17) is placed on the door (5) so as to remain behind the handle (6).
  • the handle (6) is configured to enable the users to better grasp the door (5).
  • the actuation member (17) is positioned to be hidden behind the handle (6). Thus, formation of any inconvenient appearance is prevented.
  • the door (5) of the laundry washer and/or dryer (1) is enabled to be opened/closed in an easy, quick and safe manner by means of actuation.
