TECHNICAL FIELD
[0001] The present invention relates to the technical field of household appliance, to a
water outlet mechanism and particularly to a refrigerator having the water outlet
mechanism.
BACKGROUND
[0002] A conventional refrigerator has a structural design with a function of providing
iced water. As shown in FIG. 1 through FIG. 4, a spout 1 of the structure is generally
prevented from water overflow by building a check valve 5 in the spout 1 and by fixing
a sealing ring 3. The pressure of water in a water tube 2 is controlled by turning
on or off a water valve, and the opening and closing of the check valve 5 is controlled
through the water pressure to achieve water supply.
[0003] Specifically, in FIG. 4, a first step 14 is formed between a fitting port 13 and
a spout inner chamber 11, the sealing ring 3 is disposed on a step surface of the
first step 14, and the check valve 5 is disposed in the interior of the spout inner
chamber 11. The sealing ring 3 and other portions of the spout 1 move together from
the lower left to the upper right so that the water tube 2 is inserted into the spout
inner chamber 11. However, since the size and structure of the check valve 5 and the
space limitation of the entire spout 1 cause a bearing surface of the sealing ring
3 to be too small, it is very liable to occur during the mounting of the spout 1 that
the water tube 2 drives the sealing ring 3 offset from the fitting position to between
the first step 14 and the check valve 5, so that the sealing ring fails to function
to seal, and water leakage from the position of the sealing ring 3 might occur during
actual use.

DETAILED DESCRIPTION
[0018] The present invention will be described in detail below in conjunction with specific
embodiments shown in figures 5-9. However, these embodiments are not intended to limit
the present invention. Variations can be made within the scope of the invention as
defined by the appended claims.
[0019] An embodiment of the present invention provides a water outlet mechanism, which may
be applied to a refrigerator, that is, the present embodiment also provides a refrigerator
having the water outlet mechanism. Certainly, the present embodiment is not limited
thereto.
[0020] In the present embodiment, as shown in FIGS. 1 through 2 and FIGS. 5 through 9, the
refrigerator comprises a dispenser, the dispenser comprises the water outlet mechanism,
and the water outlet mechanism is used for supplying iced water. An iced water making
device is disposed in a refrigerating chamber of the refrigerator and connected to
the water outlet mechanism. The iced water making device comprises a water valve for
opening/closing the water outlet mechanism.
[0021] Specifically, the water outlet mechanism comprises a spout 1, a water tube 2, a check
valve 5 and a sealing ring 3. The spout 1 has a hollow spout inner chamber 11, a water
outlet 12 formed at one end of the spout inner chamber 11, and a fitting port 13 formed
at the other end of the spout inner chamber 11, an end of the water tube 2 extending
from the fitting port 13 through the fitting port 13 into the spout inner chamber
11; the check valve 5 is disposed in the spout inner chamber 11 and can disengage
from the spout inner chamber 11 through the fitting port 13, a second step 15 is formed
in the spout inner chamber 11, one end of the check valve 5 abuts against the second
step 15, and the second step 15 restricts the movement of the check valve 5 toward
the water outlet 12; the check valve 5 has an open state and a closed state, to control
the remaining water in the water tube 2 and the spout inner chamber 11 not to flow
out.
[0022] The refrigerator is provided with a press button 6 which serves as a switch. The
press button 6 is triggered to control the opening and closing of the water valve.
The water valve controls water to flow into or out of the water tube 2. When the water
valve is opened, the water pressure drives the check valve 5 to open, and water flows
out of the water outlet 12 of the spout 1. When the water valve is closed, the water
pressure in the water tube 2 weakens and does not suffice to open the check valve
5, the check valve 5 closes the water outlet 12, and the water in the water tube 2
and the spout inner chamber 11 remains inside.
[0023] The sealing ring 3 is sealingly sleeved between the outside of the water tube 2 and
the inside of the spout 1, and the sealing ring 3 restricts the water in the spout
inner chamber 11 from overflowing from the fitting port 13; the sealing ring 3 is
elastic. While the water tube 2 is inserted through the fitting port 13 into the spout
inner chamber 11, the sealing ring 3 is pressed by the water tube 2 and the spout
1 to deform elastically to fill a gap between the water tube 2 and the spout inner
chamber 11. As shown in FIG. 5 or FIG. 6, the spout 1 moves towards the upper right
as shown until the water tube 2 is inserted from the lower left into the interior
of the spout inner chamber 2. A direction in which the water tube 2 moves relative
to the spout 1 is set as a first direction, namely, the lower left as shown. The water
in the water tube 2 flows towards the lower left. The sealing ring 3 restricts the
water from overflowing towards the fitting port 13 on the upper right.
[0024] As mentioned in the BACKGROUND, it is very liable to occur during the mounting of
the spout 1 that the water tube 2 drives the sealing ring 3 offset from the fitting
position to between the first step 14 and the check valve 5, so that the sealing ring
fails to function to seal, and water leakage from the position of the sealing ring
3 might occur during actual use.
[0025] In the present invention, the water outlet mechanism further comprises a support
4 assembled in the spout inner tube 11, said support 4 supporting the sealing ring
3, so that the sealing ring 3 is not prone to misalignment such that water overflow
is impossible. The technical solutions of the present invention will be introduced
below in conjunction with three specific embodiments of the water outlet mechanism
shown in figures 5-9. The extent of protection of the present invention is not limited
to these specific embodiments but is defined by the claims.
Embodiment 1
[0026] The water outlet mechanism further comprises:
a support 4 assembled in the spout inner chamber 11, wherein the sealing ring 3 abuts
against a side of the support 4 facing away from the check valve 5, the support 4
extends from the spout 1 towards a central axis of the spout inner chamber 11, the
movement of the support in the first direction is restricted, and the sealing ring
3 abuts against the support 4.
[0027] The water tube 2 comprises a water tube body 21 defining the end of the water tube
2, and an assembly terminal 22 sleeved on the outside of the water tube 2 body. When
the end of the water tube 2 extends through the fitting port 13 into the spout inner
chamber 11, the assembly terminal 22 abuts against the sealing ring 3, and the assembly
terminal 22 prevents the sealing ring 3 from moving in a direction opposite to the
first direction.
[0028] The support 4 has a cylindrical shape, the water tube 2 runs through the cylindrical
support 4, and the cylindrical structure of the support 4 is adapted for the space
in the spout inner chamber 11. In general, a cross section of the spout inner chamber
11 is circular. The cross-section of a surface adapted for the spout inner chamber
11 is also circular. An outer diameter of the spout inner chamber 11 is smaller than
an inner diameter of the spout inner chamber 11. If the cross section of the spout
inner chamber 11 is set in other shapes, the cross section of the support 4 is also
made in the corresponding shapes.
[0029] A step is provided on a side wall of the spout inner chamber 11, the support 4 is
provided between the step and the sealing ring 3, the step is named the first step
14 in the figures, and the support 4 abuts against the first step 14.
[0030] In the present embodiment, the support 4 is a T-shaped cylinder 4a. As shown in FIG.
6 or FIG. 7, the T-shaped cylinder 4a comprises a supporting portion 41 and a flange
portion 42. The flange portion 42 has a circular ring shape. One side of the flange
portion 42 abuts against the step, and the other side of the flange portion 42 abuts
against the sealing ring 3. The supporting portion 41 is connected to the flange portion
42 and extends out of the cylinder toward the check valve 5. The supporting portion
41 is inserted into the spout inner chamber 11 in the first direction until the flange
portion 42 abuts the first step 14, and then the sealing ring 3 is mounted into the
spout inner cylinder 11 from the fitting port 13 until the sealing ring 3 abuts the
other side of the flange portion 42. The water tube 2 is inserted into the flange
portion 42 and the supporting portion 41. The first step 14 restricts the movement
of the T-shaped cylinder 4a in the first direction.
[0031] The flange portion 42 abuts against the first step 14. The supporting portion 41
reduces the area of the gap in the spout inner chamber 11 except for the water tube
2, and restricts the movement of the support 4 in the spout inner chamber 11, so that
the support 4 supports itself and the sealing ring 3 more stably and meanwhile supports
the water tube 2 and prevents water overflow caused by the misalignment of the support
4 and the sealing ring 3 when the water tube 2 is inserted.
[0032] Furthermore, the cross section of the flange portion 42 perpendicular to the first
direction is a circular ring. A width of the circular ring of flange portion 42 is
greater than a step height of the first step 14 and smaller than the width of the
circular ring of the sealing ring 3; As such, the flange portion 42 can provide a
larger supporting area relative to the first step 14, so that it supports the sealing
ring 3 more stably. Since the sealing ring 3 is in a interference-fitted state between
the water tube 2 and the spout 1 to function to support, it achieves the sealing effect.
To prevent the flange portion 42 from hindering the sealing of the sealing ring 3,
the width of the circular ring of the flange portion 42 is made smaller than the width
of the circular ring of the sealing ring 3, which can be better implemented.
[0033] As compared with the prior art, the present embodiment has the following advantageous
effects: in the water outlet mechanism, at least partial space between the sealing
ring 3 and the check valve 5 is filled by the support 4, the area of the supporting
surface of the sealing ring 3 is increased, and the sealing ring 3 is not prone to
deviate from its fitting position due to the assembling of the water tube 2, thereby
solving the phenomenon of water overflow caused by incomplete sealing of the sealing
ring 3.
Embodiment 2
[0034] The difference between the present embodiment and Embodiment 1 only lies in the structure
of the support 4. The difference will be described in detail below, and other portions
that are the same as those in Embodiment 1 will not be detailed any more here.
[0035] In the present embodiment, the support 4 is a circular ring cylinder 4b, an inner
wall of the spout inner chamber 11 forms the first step 14, and the circular ring
tube 4b and the sealing ring 3 are sequentially inserted through the fitting port
13 into the spout inner chamber 11 in the first direction until one end of the circular
ring cylinder 4b abuts against the first step 14, the other end of the circular ring
cylinder 4b abuts against the sealing ring 3, and the water tube 2 runs through the
sealing ring 3 and the circular ring cylinder 4b.
[0036] The sealing ring 3 and the first step 14 are separated by the circular ring cylinder
4b. The circular ring cylinder 4b is not prone to deformation. That is, when the water
tube 2 presses the sealing ring 3 to thereby exert a pressure on the circular ring
cylinder 4b, the circular ring cylinder 4b is not deformed and pressed into between
the first step 14 and the check valve 5, thereby restricting the sealing ring 3 from
misalignment and thereby avoiding occurrence of the problem about overflow as stated
in the BACKGROUND.
[0037] Furthermore, the width of the circular ring of the circular ring cylinder 4b is greater
than the step height of the first step 14 and smaller than the width of the circular
ring of the sealing ring 3. Since the width of the circular ring of the circular ring
cylinder 4b is larger, the circular ring cylinder 4b provides a larger supporting
area relative to the first step 14 and supports the sealing ring 3 more stably.
Embodiment 3
[0038] The difference between the present embodiment and Embodiment 1 only lies in the structure
of the support 4. The difference will be described in detail below, and other portions
that are the same as those in Embodiment 1 will not be detailed any more here.
[0039] In the present embodiment, the support 4 is a hollow sleeve 4c. One end of the hollow
sleeve 4c abuts against the check valve 5, and the other end of the hollow sleeve
4c abuts against the sealing ring 3. In the present embodiment, what supports the
sealing ring 3 is the hollow sleeve 4c. At this time, the inner wall of the spout
inner chamber 11 is a straight wall, the check valve 5 restricts the movement of the
hollow sleeve 4c in the first direction, and the gap between the spout inner chamber
11 and the water tube 2 is filled by the hollow sleeve 4c.
[0040] Furthermore, the inner wall of the spout inner chamber 11 forms the first step 14;
one end of the hollow sleeve 4c abutting against the sealing ring 3 is flush with
the step surface of the first step 14, that is, the sealing ring 3 is jointly supported
by the first step 14 and the hollow sleeve 4c; while the hollow sleeve 4c fills the
spout inner chamber 11, it also supports the sealing ring 3. The present embodiment
has higher requirements for fitting accuracy and can also solve the technical problem
to be solved by the present invention.
