[0029] Reference will now be made in detail to the preferred
embodiment(s) of the present invention, examples of which are
illustrated in the accompanying drawings. Throughout the drawings,
like elements are indicated using the same or similar reference
designations where possible.
[0030] FIG. 3 is a cross-sectional view of a drum type washing
machine according to the present invention.
[0031] Referring to FIG. 3, a drum type washing machine according
to the present invention includes a base plate 51, a cabinet 52, a
tub 54, a drum 56, a motor 58, lifters 60, a front panel 62, a door
63, a top plate 64, a water supply assembly 70, a drain assembly
90, and a control panel 100.
[0032] The base plate 51 is provided to form a bottom of the
washing machine, and the cabinet 52 is provided on the base plate
51 to have open front, top, and bottom sides, The tub 54 and drum
56 are provided in the cabinet 52 to hold water and/or laundry. The
motor 58 is provided in rear of the tub 54 to be connected to the
drum 56 through a shaft. The lifters 60 are provided in the drum 56
to lift up the laundry to a predetermined height when the drum
rotates.
[0033] The front panel 62 is provided on the front side of the
cabinet 52 to have an opening through which the laundry is put in
or picked out. The door 63 is rotatably provided to the front panel
62 to open/close the opening. The top plate 64 is provided on the
cabinet 52. And, the control panel 100 is provided on the front
panel 62 to hold a control unit for controlling an operation of the
washing machine.
[0034] The water supply assembly 700 for supplying water required
for washing or rinsing the laundry to the tub 54 is provided to the
drum type washing machine. The drain assembly 90 is provided on the
base plate 51 to drain the water in the tub 54. And, the control
unit for controlling an operation of the washing machine is
installed in the control panel 100.
[0035] The drum type washing machine washes, rinses, and dewaters
the laundry in a manner that the drum 56 is driven to rotate in the
tub 54 by the motor 58.
[0036] Meanwhile, the water supply assembly 70 includes an inlet
valve 72, a detergent box 76, and an inlet hose 82.
[0037] In this case, the inlet valve 72 is turned on/off to
open/close a passage of the externally supplied water according to
a control signal of the control unit provided to the control panel
100. And, the detergent box 76 stores the detergent therein and is
provided as a passage of the water and detergent. Namely, the water
passes the detergent box 76 to be mixed with the detergent, and the
water and detergent are then supplied to the tub 54 via an inlet
bellows 75.
[0038] Meanwhile, one end of the inlet hose 82 is connected to a
second hose connecting portion 74 formed at the inlet valve 72 and
the other end of the inlet hose 82 is connected to a first hose
connecting portion 78 formed at the detergent box 7. Hence, the
inlet hose 82 leads the water supplied from the inlet valve 72 to
the detergent box 76.
[0039] In this case, a height h1 of the second hose connecting
portion 74 connected to the inlet valve 72 is provided higher than
a height h2 of the first hose connecting portion 78 connected to
the detergent box 76. Hence, the inlet hose 82 is provided slant
between the first and second hose connecting portions 78 and 74
with a predetermined slope. Hence, the water in the inlet hose 82
naturally flows in the detergent box 76, thereby failing to remain
in the inlet hose 82.
[0040] The first hose connecting portion 78 is formed like a pipe
protruding from one rear side of the detergent box 76 and is built
in one body of the detergent box 76. Moreover, the second hose
connecting portion 74 is formed like a pipe protruding from one
front side of the inlet valve 72 and is built in one body of the
inlet valve 72.
[0041] Besides, the inlet hose 82 may be formed of a flexible
material. Instead, in order to prevent the inlet hose 82 from
drooping like a `U` shape due to weight of the water, the inlet
hose 82 is preferably formed of a stiff material.
[0042] And, the inlet hose 82 can be provided as a slant straight
line between the first and second hose connecting portions 78 and
74.
[0043] Moreover, the inlet hose 82, as shown in FIG. 3, can be
partially bent to be installed slant in the washing machine.
[0044] The inlet valve 72 is installed at the rear side of the
cabinet 52 through a screw or hook, and a third hose connecting
portion 73 is provided at a hole 52a formed at an upper rear side
of the cabinet 52. A rear end of the third hose connecting portion
73 is connected to a hose 88 connected to a service pipe, and a
front end of the third hose connection portion 73 is a portion of
the second hose connecting portion 74 protruding like a pipe so
that one end of the inlet hose 82 is fitted thereto.
[0045] Moreover, the first hose connecting portion 78 protrudes
like a pipe from a lower rear side of the detergent box 76 so that
the other end of the inlet hose 82 is fitted thereto.
[0046] An operation of the water supply assembly of the drum type
washing machine according to the present invention is explained as
follows.
[0047] First of all, once the drum type washing machine operates to
turn on the inlet valve 72, the water passes the inlet valve 72,
inlet hose 82, detergent box 76, and inlet bellows 75 in turn via
the external hose 88 and then flows in the tub 4 and the drum
6.
[0048] Since the second hose connecting portion 74 of the inlet
valve 72 is disposed higher than the first hose connecting portion
78 of the detergent box 76, the water passing inside the inlet hose
82 enables to smoothly flow in the detergent box 76. Moreover, the
water lingering in the inlet hose 82 naturally flows toward the
first hose connecting portion 78 of the detergent box 76, thereby
completely flowing into the detergent box 76.
[0049] Accordingly, the apparatus for water supply of the drum type
washing machine according to the present invention has the
following advantages or effects.
[0050] First of all, the first hose connecting portion of the inlet
valve connected to one end of the inlet hose is disposed higher
than the second hose connecting portion of the detergent box
connected to the other end of the inlet hose. Hence, the water
flowing inside the inlet hose is immediately supplied to the
detergent box and fails to remain in the inlet hose, whereby the
inlet hose is prevented from being frozen to breakage.
[0051] It will be apparent to those skilled in the art that various
modifications and variations can be made in the present invention
without departing from the spirit or scope of the invention. Thus,
it is intended that the present invention cover such modifications
and variations, provided they come within the scope of the appended
claims and their equivalents.
