Water dispenser description
BACKGROUND OF THE INVENTION
[0001] The present invention relates generally to a bottled type
water dispenser and, more particularly, to a unitary seat of water
inlet and venting pipe of a bottled type water dispenser. The bottled
type water dispenser is easily fabricated and assembled, and the
interior thereof is easily cleaned.
[0002] The conventional water dispenser typically includes a filter
mechanism installed on a bottled type water storage device. The
water storage device is inversely disposed on/in the water dispenser,
allowing water contained therein to flow into the water dispenser.
For example, in U.S. Pat. No. 6123232 the water dispenser includes
a generally cylindrical liquid reservoir normally open at its upper
end for receiving liquid from an inverted bottle having a downwardly
and inwardly sloping shoulder portion merging into a depending neck
portion defining a discharge opening, said liquid dispensing device
comprising, in combination, a top support having a generally centrally
disposed annular opening with a depending skirt portion dimensioned
for reception in the open upper end of said reservoir, said top
support defining a generally annular ring portion for supporting
said shoulder portion of said inverted bottle above said liquid
reservoir and wherein said top support includes a downwardly extending
peripheral margin for generally centering said annular opening over
said reservoir, a feed tube comprising a generally cylindrical outer
portion and a substantially hollow interior defining at least one
flow path for dispensing liquid from said inverted bottle into said
reservoir and for admitting replacement air from said reservoir
into said bottle, means for mounting said feed tube in upstanding
relation in the upper portion of said reservoir, said mounting means
including a cup-shaped structure formed integrally with and supporting
said upstanding feed tube in generally centered relation with respect
to said annular opening and said reservoir, said cup-shaped structure
having an inwardly stepped sidewall and an upper portion for suspending
said integral feed tube and cup-shaped structure from said top support,
and means defining an opening through said cup-shaped structure
radially outwardly from said feed tube for admitting air into the
upper end of said reservoir.
[0003] In the above-mentioned conventional water dispenser, the
top support, the feed tube and the cup-shaped structure are all
independent members requiring opening multiple molds for fabrication.
Some of such members are difficult to install, and too many separate
members also cause inconvenience of assembly. Further, it is very
laborious and time-consuming for cleaning the internal storage tank
or the cold or hot water tub since all of the members have to be
detached from the water dispenser.
BRIEF SUMMARY OF THE INVENTION
[0004] The present invention provides a bottle type water dispenser
which can be easily fabricated, assembly and used.
[0005] The bottle type water dispenser provided by the present
invention includes a water tank in a body thereof. The body and
the water tank each have an opening. A detachable seat of water
inlet and venting pipe is installed on the openings. The seat of
water inlet and venting pipe includes an integrally formed structure
and is directly connected to the body. The seat of water inlet and
venting pipe includes a water inlet and venting pipe, allowing a
mouth of the water bottle inserted therein. Therefore, as the water
assembly requires only the connection of the seat of water inlet
and venting pipe, the body and the water tank, it is easily dissembled
to clean the water tank.
[0006] An air inlet port is formed on a top portion of the water
tank. A one-way valve is mounted at the air inlet port. When the
water tank has a full water level, the one-way valve is pressurized
by the water to block the air inlet port. Therefore, no water or
air can flow through the air inlet port. When the water level drops,
the one-way valve falls due to gravitation to leave the air inlet
port open. Therefore, air flows from the air inlet port allowing
fluent water dispense.
[0007] The present invention is further characterized in applying
a sealing member between the seat of water inlet and venting pipe
and the water tank. The sealing member includes a circular sealing
ring.

DETAILED DESCRIPTION OF THE INVENTION
[0014] Referring to FIGS. 1 and 4 a water bottle 5 filled with
water is installed on top of a water dispenser 1 to provide drinking
water for the water dispenser 1. As shown in FIGS. 2 and 3 the
body 11 of the water dispenser 1 includes a water tank 2 at a top
portion thereof. The body 11 and the water tank 2 have an opening
111 and 21 respectively. The water tank 2 is partitioned into an
upper chamber 23 and a lower chamber 24 by a partitioning board
22. Two outlet apertures 221 222 are formed on the partitioning
board 22. The outlet aperture 221 allows the water contained in
the upper chamber 23 flowing into the lower chamber 24 while the
other outlet aperture 222 is connected to a water tap12 or a hot
water tub via a an outlet pipe 25 as shown in FIG. 1. A cooler 3
is formed on the exterior wall of the lower chamber 24 such that
water contained in the lower chamber 24 is cooled down to become
cold water. An outlet aperture 241 is formed on a bottom portion
of the lower chamber 24. The outlet aperture 241 is connected to
a water tap 13 (as shown in FIG. 2) via an outlet pipe 26. The water
tank 2 is covered with shielding material 27 such as polyfoam.
[0015] Referring to FIGS. 2 and 3 in the present invention, a
detachable seat of water inlet and venting pipe is installed at
the openings 111 21 of the body 11 and the water tank 2. The seat
of water inlet and venting pipe 4 includes a U-shape seat 41 with
a predetermined depth allowing the mouth 51 of the water bottle
5 inserted therein. The periphery of a top portion of the U-shape
seat 41 extends outwardly and inclined upwardly to form a contact
surface 42. The free end of the contact surface 42 further extends
to form an inverse L-shape fastening part 43. A plurality of equal
distant latches 44 are formed on a bottom end of the fastening part
43 while apertures 112 are formed on the body 11 for receiving
the latches 44.
[0016] In the present invention, a hollow water inlet and venting
pipe 45 extends from a central bottom portion of the U-shape seat
41. The water inlet and venting pipe 45 includes a water inlet aperture
451 and a venting aperture 452 on a sidewall thereof. A sealing
member is mounted between the water inlet and venting pipe 4 and
the water tank 2. In one embodiment, the sealing member includes
a circular sealing ring 6 of which a clipping socket 61 is formed
on an exterior sidewall thereof to be engaged with a rim of the
opening 21 of the water tank 2. Thereby, the sealing ring 6 seals
the tank 2 and the water inlet and venting pipe 4.
[0017] Referring to FIG. 3 in the present invention, an air inlet
port 28 is formed on the top portion of the water tank 2. A one-way
valve 7 is mounted on the air inlet port 28. When the water tank
2 has a full water level, the water level push the one-way valve
7 upwardly, such that the air inlet port 28 is filled by the one-way
valve 7 and water in the water tank 2 cannot overflows through
the air inlet port 28. When the water tap 12 (or 13) of the water
dispenser 1 is switched on, water level drops to release pressure
against the one-way valve 7. The one-way valve 7 thus descends due
to gravitation, such that air flows in through the air inlet port
29 and water flow is fluent.
[0018] Referring to FIGS. 2 and 3 while assembly the water dispenser,
the seat of water inlet and venting pipe 4 is installed on the openings
111 21 of the body 11 and the water tank 2. The sealing ring 6
is mounted on a periphery of the U-shape seat 41. The clip socket
61 formed on the exterior side of the sealing ring 6 is engaged
with the edge of the opening 21 of the water tank 2. Therefore,
the water tank 2 and the seat of water inlet and venting pipe 4
are sealed. The latching members 44 formed on the latching portion
43 of the seat of water inlet and venting pipe 4 are received in
the apertures 112 such that a water inlet and venting pipe 45 is
installed on top of the water dispenser 1 and connected to the body
11 and the water tank 2.
[0019] When the water dispenser 1 is in use, as shown in FIG. 4
the mouth 51 of the water bottle 5 is inversely inserted into the
U-shape body 41 such that the water inlet and venting tube 45 is
inserted into the mouth 51 allowing water flowing from the water
bottle 5 into the water tank 2 through the water inlet aperture
451 of the water inlet and venting pipe 45 and air flowing from
the water tank 2 to the water bottle 5 through the venting aperture
452. By the air pressure, water in the water bottle 5 flows into
the water tank 2 while water contained in the upper chamber 23
flows to the lower chamber 24 through the water outlet aperture
221 of the partitioning board 22. The water in the lower chamber
24 is cooled down by the cooler 3 while water in the upper chamber
23 is fed into a hot water tube for via a pipe 25 for heating. The
water dispenser 1 thus can provide cold water and cold water.
[0020] In the present invention, once the water tank 2 has a full
water level, the water push against the one-way valve to block the
air inlet port 28. Therefore, water in the water tank 2 will not
overflows the body 11 and external air will not enter the water
tank 2 through the air inlet port 28 as shown in FIG. 4.
[0021] As shown in FIG. 5 once eh tap 12 (or 13) of the water
dispenser 1 is switched on and water level of the water tank 2 drops,
the upward pressure against the one-way valve 7 no longer exists.
The one-way valve 7 thus falls by gravitation and releases from
the air inlet port 28. Therefore, air can enters the water tank
2 allowing fluent flow of water dispense from the tap 12 (or 13).
[0022] In the present invention, a unitary seat of water inlet
and venting pipe is used to conveniently assemble the body 11 and
the water tank 2 together. To clean the water tank 2 only by detaching
the seat of water inlet and venting pipe 4 the openings 111 21
of the body 11 and 2 are exposed, and the water tank 2 can be easily
cleaned.
[0023] Other embodiments of the invention will appear to those
skilled in the art from consideration of the specification and practice
of the invention disclosed herein. It is intended that the specification
and examples to be considered as exemplary only, with a true scope
and spirit of the invention being indicated by the following claims.
