Description

FIELD OF THE INVENTION

The present invention relates to a laundry appliance, such as a clothes dryer or clothes washer having a front control panel assembly for use with a vertically extending front panel and, in particular it relates to the assembly of the control panel to the laundry appliance.

BACKGROUND OF THE INVENTION

Laundry appliance front control panel assemblies typically comprise a control panel which has dials or buttons manipulated by the user to direct the operation of the clothes dryer or washer. Posterior to the control panel is a heat shield to which the control panel may be mounted. Located therebetween is a circuit board or electronic board configured to respond to input from the control panel. The front control panel assembly is mounted to an upper portion of the main cabinet of the appliance.

In the past, laundry appliances typically comprised a vertically extending front panel. The control panel is typically secured to the heat shield via a screw received by the control panel from the rear. Other embodiments include screws which pass through the control panel from the front to be received by a support panel or member. Prior to the attachment of the screw, the control panel must be held in place. This is often done manually, which can create difficulty for an assembler trying to secure the panel with a screw.

BRIEF DESCRIPTION OF THE INVENTION

The present invention relates to a laundry appliance having a main cabinet, a support panel secured to an upper portion of the main cabinet and a control panel coupled with the cabinet via the support panel.

In accordance with one embodiment of the present invention there is provided a control panel coupled with the main cabinet of the laundry appliance via the support panel. The support panel is secured to an upper portion of the main cabinet. One of the support panel and the control panel has at least two spaced apart cantilever posts each comprising a shaft portion having a first diameter and an axis and an end portion having a second diameter greater than the first diameter. The other one of the support panel and the control panel has at least two spaced apart support brackets depending therefrom. Each of the support brackets receives the end portion of a corresponding one of the cantilever posts in a first radial direction to prevent axial movement of the support bracket along the axis of the corresponding cantilever post. Each support bracket also permits radial movement of the bracket relative to the cantilever post and a second radial direction opposite to the first radial direction.

By providing at least two spaced apart corresponding cantilever posts and support brackets in co-operation with each other, the control panel can be readily positioned relative to the support panel. Positioning the end portion of each cantilever post within a support bracket prevents the panel from moving forward and backward relative to the support panel.

In accordance with another embodiment of the present invention, the support panel is a heat shield which has a main body and has at least two spaced apart cantilever posts. Each cantilever post may comprise a wheel and a shoulder screw passing therethrough for attachment to the heat shield.

The threaded shaft portion comprises a first diameter and the end portion comprises a second diameter greater than the first diameter. The control panel has at least two spaced apart support brackets comprising a wall surface portion having a slot comprising a width that is less than the first diameter of the wheel. Each of the slots receives the shoulder screw of a corresponding one of the cantilever posts with the surface portion of the slot sandwiched between the heat shield main body and the wheel whereby the cantilever post and support bracket co-operate to prevent axial movement of the support bracket along the axis of the corresponding cantilever post and permit radial movement of the bracket relative to the cantilever post in a first radial direction and a second radial direction opposite the first radial direction.

In accordance with another embodiment of the present invention, each support bracket may comprise a slot having an opening, a trough and a clasp portion for capturing the cantilever post shaft portion. The clasp portion is characterized by two protuberances, with one at each junction of the trough and the guiding portion. The opening of the clasp portion has a distance thereacross slightly less than the first diameter of the shaft portion of the cantilever post. The trough has a diameter the same as the first diameter of the shaft portion of the cantilever post. The clasp portion and the trough provide a means of locking into place the shaft portions of the cantilever posts. This facilitates a more secure engagement between the control panel and the support panel.

In accordance with yet another embodiment of the present invention, each support bracket comprises a wall surface portion comprising a slot and is configured to guide into place the shaft portion of the cantilever post by means of a guiding portion having two symmetrically disposed convergent wall portions extending lateral to the slot. The guiding portion of the slot facilitates easier alignment of the support brackets with the cantilever posts. This permits easier assembly of the control panel assembly.

In a further embodiment, the control panel is positively fastened to the support panel by a screw which passes through a recessed opening in the control panel and is received by the support panel. The screw and recessed opening are covered by a removable appliance control knob. Front access to the screw renders assembly and disassembly of the control panel assembly much more convenient. The recessed opening provides easy access to the screw, but the control knob gives an aesthetically pleasing look to the appliance when the clothes dryer or washer is in normal use.

In another embodiment, the control panel may further comprise rearwardly depending peripheral wall portions each having rear peripheral edges for at least partially supporting the support brackets adjacent thereto.

In another embodiment of the present invention, the heat shield has four cantilever posts, the control panel has four corresponding spaced apart support brackets comprising two upper support brackets and two lower support brackets.

The guiding portion 40 is characterized by two symmetrically disposed convergent wall portions 42 and 44 lateral to the trough 34. The convergent wall portions 42, 44 facilitate guiding of the cantilever posts 20 into the slots 38. The four spaced apart support brackets 58, 60 further comprise two upper support brackets 58 and two lower support brackets 60. The lower support brackets 60 further comprise a socketed wall portion 64 depending from the wall surface portion 36. As shown in FIG. 7, the socketed wall portion 64 comprises a receiving pocket 66 having a third diameter 67 slightly greater than the first diameter of the wheel 26. The socketed wall portion 64 serves as a means of properly positioning the wheel 26 relative to the wall surface portion 36 during engagement of the cantilever post 20 by the support bracket 58, 60. The upper support brackets 58 further comprise a side wall 106 that is opposite the rear peripheral edge 102. The side wall 106 serves to better secure the wheel 26 into position while the cantilever post 20 co-operates with the upper support bracket 58. The slots 40 of the upper support brackets 58 further comprise a clasp portion 30 for capturing the shoulder screw 22 of the cantilever post 20. The clasp portion is characterized by two protuberances 70, one at each junction of the guiding portion 40 and the trough 34. The clasp portion 30 has a distance thereacross slightly less than the first diameter of the shoulder screw 22. The trough 34 has a diameter that is the same as the first diameter of the shoulder screw 22. The shaft portion 22 is embraced within the trough 34 by the clasp portion 30 when the cantilever posts 20 co-operate with the lower support brackets 60.
