Description
BACKGROUND OF THE INVENTION
[0001] Washing machines include compartments for holding various
additives, such as detergent, bleach, and fabric softener. These
compartments are typically formed in the cabinet of the washing
machine, with hoses or conduits leading from a water supply to the
compartments to flush the additive to the washing machine drum at
the appropriate time during the wash and rinse cycles. The hoses
and conduits must extend around the access opening in the top of
the cabinet, and thus generally take long curved paths to reach the
various additive compartments.
[0002] While most machines are adapted to receive liquid or
particulate detergent, some consumers prefer detergent tablets. The
tablets typically are difficult to flush away with flowing water,
such that the use of detergent tablets is less than ideal.
[0003] It is also desirable to provide a pre-wash wet down or
shower of clothes or laundry in the drum, particularly for large
loads. However, conventional washing machines typically have a very
small area of shower holes, which does not optimize the wet
down.
[0004] Accordingly, a primary objective of the present invention is
the provision of a washing machine with an improved water and
chemical delivery system.
[0005] Another objective of the present invention is the provision
of a washing machine having a lid with water channels formed
therein for directing water to additive compartments.
[0006] Another objective of the present invention is the provision
of a washing machine having a detergent compartment adapted to
receive detergent tablets which can be effectively flushed away
with flowing water.
[0007] A further objective of the present invention is the
provision of a washing machine having an enlarged area of shower
holes for wetting down laundry in the tub.
[0008] Another objective of the present invention is the provision
of a washing machine wherein the water delivery system is formed in
the lid of the machine.
[0009] Another objective of the present invention is the provision
of a washing machine wherein the detergent compartments are in the
lid of the washing machine.
[0010] A further objective of the present invention is the
provision of a washing machine wherein the wet down shower holes
are in the lid of the machine.
[0011] These and other objectives will become apparent from the
following description.
SUMMARY OF THE INVENTION
[0012] An improved washing machine is provided with a water
delivery system formed in the lid for delivering water to various
additive compartments in the washing machine. The water delivery
system includes water channels molded into the lid. The additive
compartments include a detergent compartment in the lid, with the
water delivery system having outlets for flushing detergent from
the detergent compartment. The detergent compartment can dispense
detergent in the form of liquid, powder, or tablets. The detergent
compartment may include a ceiling wall with ribs adapted to space a
detergent tablet above the ceiling wall to enhance exposure of the
tablet to water. The ribs are sloped to facilitate discharge of the
tablet into the tub of the washing machine.
[0013] The additive compartments also include a bleach compartment
and a fabric softener compartment in the cabinet, with the water
delivery system having outlets to direct water into the bleach and
fabric softener compartments. The water delivery system also
includes a plurality of shower holes to provide a wet down to
laundry in the tub. A water trap is formed in the water delivery
system to retain water when the lid is raised from the closed
position, thereby preventing water from accidentally splashing on
the user or into the drum when the lid is raised.

DETAILED DESCRIPTION OF THE DRAWINGS
[0025] The lid assembly 10 of the present invention is intended for
use on a vertical axis washing machine. As seen in FIG. 9, the
washing machine includes a cabinet 12 with an opening 14 providing
access to the inner drum (not shown).
[0026] The lid assembly 10 includes an outer lid 18 and an inner
lid 20. The outer lid 18 is preferably made of sheet metal and is
porcelain coated. The inner lid 20 is preferably made of plastic
and is secured to the outer lid 18 without the use of screws or
other fasteners which penetrate the outer lid 18, as described
below.
[0027] As best seen in FIG. 4, the outer lid 18 includes a front
edge 22, a rear edge 24, and opposite side edges-26. The edges 22,
24, 26 extend substantially perpendicular to the primary surface 28
of the outer lid 18. A perimeter flange or lip 30 extends inwardly
from the edges 22, 24, 26.
[0028] A pair of mounting or retainer brackets 32 reside along the
side edges 26 adjacent the rear corners 34 of the outer lid 18. The
brackets 32 are held in position by the perimeter flange 30 of the
outer lid 18. Each bracket 32 includes a key slot 36 and a snap
receiver 38. Each bracket 32 also includes a pin or post 40 which
extends through a hole 42 in the side edges 26 adjacent the rear
corners 34 of the outer lid 18. The pins 40 are also received in
corresponding holes (not shown) in the cabinet 12 adjacent the
access opening 14, thereby defining a horizontal pivot axis which
allows the lid assembly 10 to move between open and closed
positions relative to the access opening 14.
[0029] The inner lid 20 includes a front or outer surface 44 and a
rear or inner surface 46. The inner lid 20 also includes a front
edge 48, a rear edge 50, and the opposite side edges 52. As seen in
FIG. 5, a pair of key tabs or locking tabs 54 extend from the inner
surface 46 adjacent the opposite side edges 52 of the inner lid 20.
The key tabs 54 are adapted to be received in the key slots 36 of
the retainer brackets 32. The key tabs 54 generally have a T-shaped
structure with a head and a leg. The key slots 36 include a lower
end sufficiently large to receive the head of the key tabs 54, and
a narrow upper portion which receives the leg of the key tabs 54
while retaining the head thereof.
[0030] The inner lid 20 also includes a pair of snap tabs 56
adjacent the rear edge 50. The snap tabs 56 are adapted to be
received in the snap receivers 38 of the retainer brackets 32. The
snap tabs 56 are inserted into the snap receivers 38 after the key
tabs 54 are slid upwardly into the narrow portion of the key slots
36. As the key tabs 54 are slid into the key slots 36, the front
edge 48 of the inner lid 20 is received under the perimeter flange
30 adjacent the front edge 22 of the outer lid 18. Spacer tabs 58
are formed in the front edge 48 of the inner lid 20 so as to
provide a snug fit in the front edge 22 of the outer lid 18.
[0031] The front surface 44 of the inner lid 20 includes a recess
60 for receiving a detergent dispenser 62. More particularly, a
pair of slots 64 are provided in the inner lid 20 adjacent the rear
edge 50 thereof. The slots 64 are adapted to receive mounting tabs
66, which also extend under or capture the perimeter flange 30 of
the outer lid adjacent the rearward edge 24 thereof. The upper end
of the detergent dispenser 62 includes a snap tab 68 which is
adapted to snap fit into a shoulder 70 in the inner lid 20. A
recess 72 is provided above the shoulder 70 so that a person can
use his/her finger to push the resilient snap tab 68 out of
engagement with the shoulder 70 to remove the detergent dispenser
62 from the inner lid 20.
[0032] The detergent dispenser 62 includes a compartment 74 to
receive liquid detergent and a compartment 76 to receive powder
detergent. A water inlet 78 is formed in the detergent dispenser 62
and resides adjacent the rear edge 50 of the inner lid 20. The
water inlet 78 directs water into each of the compartments 74, 76,
as shown by the arrows in FIG. 8, to flush the respective detergent
into the drum of the washing machine during the wash cycle of the
machine operation. The compartment has a ceiling wall 77 and a
wedge projection 79 which is sloped to facilitate flush-out of the
detergent into the drum. Water is also directed to the upper end of
the detergent dispenser for exit through holes 80 to provide a
pre-wet shower for laundry in the drum. The liquid compartment 74
includes a conventional stand pipe 82 so that liquid detergent is
not flushed from the compartment 74 until water is introduced
through the water inlet 78. The stand pipe 82 is formed as part of
the detergent dispenser 62. A siphon cover (not shown) is placed
over the stand pipe 82 to create a siphon system. The stand pipe 82
and siphon cover extend through a hole on the back of the detergent
dispenser and is secured by a twist lock.
[0033] The compartment 76 is also adapted to hold a detergent
tablet. The compartment has a bottom wall 73 and ribs or
projections 75 which spaces the tablet from the bottom wall 73, so
as to enhance water contact with the tablet. The ribs 75 are also
sloped to facilitate discharge of the tablet into the drum.
[0034] The inner lid 20 includes a pair of water inlets 84 adjacent
the rear edge 50 thereof. The water inlets 84 are formed on the
front surface 44 of the inner lid 20. A pair of water channels 86
are provided on the rear surface 46 of the inner lid 20 and
cooperate with the water inlets 84 to define a water flow path to
water outlets 88 adjacent the front edge 48 of the inner lid. The
water outlets 88 are positioned over a bleach receptacle 90 and
fabric softener receptacle 92 formed in the upper wall of the
cabinet 12, as shown in FIG. 9. Thus, at the proper times during
the wash cycle, water can be introduced through the water inlets 84
and into the water channels 86 for dispensement through the outlets
88 into the receptacles 90, 92 so as to flush bleach or fabric
softener into the drum. The water channels 86 are preferably made
of plastic and welded to the rear surface 46 of the inner lid
20.
[0035] It is common in the art to utilize rubber hoses with spring
steel clamps as the water distribution means to distribute water to
dispensers mounted on the cabinet. The hoses are relatively
expensive, and substantial installation effort is required during
assembly. The water channels 86 provide an economical water
distribution means.
[0036] The water channels 86 also include an internal dividing wall
87 which defines a water trap 89 in each of the channels 86. When
the lid assembly 10 is raised from the closed position, any water
remaining in the channels 86 will drain into the traps 89. Thereby
precluding accidental spillage onto a user or into the drum.
[0037] The inner lid 20 may also include sealing gaskets 94 which
are overmolded onto the inner lid 20 adjacent the front edge 48 and
rear edge 50. The gaskets 94 may extend partially or completely
along the side edges of the inner lid 20. The sealing gaskets 94
engage portions of the cabinet adjacent the access opening 14 when
the lid assembly 10 is closed to prevent escape of moisture during
the wash operation.
[0038] Thus, from the foregoing it is seen that the inner lid 20 is
mounted to the outer lid 18 without the use of separate fasteners
and without penetrating any portion of the outer lid 18. Also, when
the inner lid 20 is mounted on the outer lid 18, there are no
visible fasteners or connector means.
[0039] The invention has been shown and described above with the
preferred embodiments, and it is understood that many
modifications, substitutions, and additions may be made which are
within the intended spirit and scope of the invention. From the
foregoing, it can be seen that the present invention accomplishes
at least all of its stated objectives.
