Definitions

  • the present invention relates to a household appliance, in particular to a laundry dryer, a laundry washer or a dishwasher.
  • the present invention more particularly relates to the door latch assembly of the household appliance.
  • Household appliances such as laundry dryers, laundry washers and dishwashers are commonly known in the art. These household appliances each comprise a door latch assembly which includes a latch and a striker.
  • the striker is generally fixed to the main body or alternatively to the door whereas the latch is accordingly disposed onto the door or alternatively to the main body.
  • the latch engages/disengages the striker as the door is closed/opened by the user.
  • a common problem with these prior art household appliances is that the striker may become loosened from its place due to excessive mechanical stress, for instance, as a result of frequent opening and closing of the door. In such incidents, the door cannot be properly closed, and thus the users report the failure to the customer service. Consequently, the user satisfaction decreases. Therefore, it is generally important that the striker is securely retained in place.
  • US 2014/0265378 A1 discloses a prior art household appliance which has a latch (cf. locking protrusion) and a striker (cf. locker). In this household appliance the striker is fixed to the door by means of screws.
  • An objective of the present invention is to provide a retainer for use in the door latch assembly of a household appliance which solves the aforementioned problems of the prior art in a cost effective way and which enables an improved production and assemblage.
  • the main body has one or more snap-in holes
  • the striker has one or more snap-in hooks for releasably engaging with the respective snap-in hole.
  • the retainer of the present invention comprises: one or more blocking members each for blocking sideways movement of the respective snap-in hook relative to the respective snap-in hole; and an attachment means for detachably attaching each blocking member to the main body.
  • a major advantageous effect of the present invention is that by virtue of snap-in holes and the snap-in hooks, the striker can be easily engaged to the main body. Thereby, the production and assemblage of the striker has been improved, and the overall cost has been comparatively reduced both in labor and material.
  • Another major advantageous effect of the present invention is that by virtue of the blocking members, the striker can be securely retained in place. Thereby, the risk that the striker becomes loosened from the main body has been eliminated or reduced as much as possible. Thereby, the user satisfaction can be improved.
  • the striker has two snap-in hooks.
  • This embodiment is particularly advantageous as the striker can be rendered symmetrical, and thus the assemblage can be expedited.
  • the sloping surfaces of the snap-in hooks are arranged to be turned away from each other. And the snap-in hooks flex towards each other when being snapped into the respective snap-in holes.
  • the retainer has two blocking members which are located between the two snap-in hooks, and block sideways movement of the two snap-in hooks towards each other. During the assembly of the household appliance, after the striker is snapped in place, the retainer is attached to the main body. Thereby, the sideway movements of the snap-in hooks are blocked.
  • the sloping surfaces of the snap-in hooks are arranged to face each other. And the snap-in hooks flex away from each other when being snapped into the respective snap-in holes.
  • the retainer has two blocking members which are respectively located to the left and to the right of the two snap-in hooks and block sideways movements of the two snap-in hooks away from each other.
  • the snap-in hooks are supported by the retainer from below through respective lower abutments. This embodiment is particularly advantageous as a firm connection can be established between the retainer and the striker, and thus any clearance can be removed.
  • the retainer may be attached to the main body through various different type of connections.
  • the retainer may be attached to the main body by a snap connection, an interlocking connection, a clamping connection, a screw connection.
  • Other type of connections known to those skilled ⁇ n the art can be alternately used.
  • the attachment means comprises two snap-in claws which releasably engage with the respective snap-in apertures on the main body. This embodiment is particularly advantageous as the retainer can be quickly assembled with the main body.
  • a household appliance in particular a dishwasher may be provided as a free standing type appliance or a built-in type appliance. Therefore, in another embodiment, the retainer is further adapted for use with a free-standing type household appliance, in particular a free standing dishwasher which has a cover plate for covering at least part of the upper surface of the appliance.
  • the retainer has an upper abutment which abuts against the cover plate from below. In a version of this embodiment, the retainer abuts against the front section of the cover plate from below.
  • the retainer is further adapted for use with a built-in type household appliance, in particular a built-in type dishwasher, wherein the cover plate is omitted. In this embodiment, the upper abutment of the retainer is also omitted.
  • the retainer is single piece which is preferably made from a resilient plastic material. This embodiment is particularly advantageous as the number of parts can be further reduced.
  • the retainer may be manufactured through a moulding process.
  • the striker has a stop which abuts onto the periphery of a mounting passage in the main body. This embodiment is particularly advantageous as the stop prevents the retainer from receiving mechanical stress.
  • the striker and the retainer are both attached to a cross beam of the main body.
  • This embodiment is particularly advantageous as the cross beam is easily accessible when the cover plate is removed.
  • Figure 1 - is a schematic perspective view of a retainer according to an embodiment of the present invention.
