Description
FIELD OF THE INVENTION
[0001] The present invention relates to a vapor recovery and water
collection box structure of a heating barrel, and more particularly
to a vapor recovery and water collection box structure applied to a
build-in closet hot water dispenser.
BACKGROUND OF THE INVENTION
[0002] A build-in closet hot water dispenser, as shown in FIG. 7,
comprises a vapor and water collection box 40, a heating barrel 50,
and a kitchen faucet 60. The top side of the vapor and water
collection box 40 is provided with a vapor inlet connecting tube 41
and a vapor outlet connecting tube 42. The bottom side of the
heating barrel 50 has a water inlet 51. The water inlet 51 is
connected with a cold water inlet tube 510. The heating barrel 50
is provided with a heating device 52 disposed close to its bottom
edge thereof. The top side of the heating barrel 50 is provided
with a hot water outlet tube 53. The side of the hot water outlet
tube 53 has a vapor guide outlet 530. The kitchen faucet 60
comprises an outer tube 61 and an inner tube 62 in the outer tube
61. The outer tube 61 has a vapor vent 610 disposed close to its
bottom edge thereof. The vapor inlet connecting tube 41 of the
vapor and water collection box 40 is connected with the vapor guide
outlet 530 of the hot water outlet tube 53 of the heating barrel
50. The vapor outlet connecting tube 42 of the vapor and water
collection box 40 is connected with the vapor vent 610 of the outer
tube 61 of the kitchen faucet 60. The hot water outlet tube 53 of
the heating barrel 50 is connected with the inner tube 62 of the
kitchen faucet 60. When the water stored in the heating barrel 50
is heated, the vapor generated by heating is guided from the vapor
inlet connecting tube 41 to the vapor and water collection box 40
through the vapor guide outlet 530 of the hot water outlet tube 53,
and then the vapor is guided to the vapor outlet connecting tube 42
and exhausted from the vapor vent 610 of the outer tube 61 of the
kitchen faucet 60. When the vapor is exhausted, the outer tube 61
of the kitchen faucet 60 will generates heat which may scald the
user. Besides, the water inlet 51 is disposed at the bottom side of
the heating barrel 50, which may cause water seepage. Accordingly,
the inventor of the present invention has devoted himself based on
his many years of practical experiences to solve these
problems.
SUMMARY OF THE INVENTION
[0003] In view of the shortcomings of the conventional build-in
closet hot water dispenser that is not safe for use and may cause
water seepage, a vapor recovery and water collection box structure
of a heating barrel of the present invention is achieved.
[0004] The primary object of the present invention is to provide a
vapor recovery and water collection box structure of a heating
barrel. The present invention comprises a vapor box, a heating
barrel unit, and a faucet. The vapor box includes an upper box lid
and a lower box tray. The upper box lid has a first guide opening,
a second guide opening, and an air inlet. The first guide opening
is fixedly connected with a backflow connecting tube. The second
guide opening is fixedly connected with a check valve connecting
tube. The air inlet is provided with a non-return air inlet valve.
The upper box lid and the lower box tray are sealed against each
other to form an accommodation chamber therebetween. The
accommodation chamber is provided with a water collection trough
and a float ball seat above the water collection trough. The float
ball seat has a plurality of float ball limit grooves defined
therein. A bottom side of each float ball limit groove is formed
with a guide hole. An inner side of the guide hole is provided with
a check ring. A float ball is provided above the check ring. The
float ball is able to float and displace relative to the
corresponding float ball limit groove. The heating barrel unit
includes a barrel body. A top side of the barrel body is provided
with a water inlet duct and a water outlet duct. The barrel body is
provided with a heating controller disposed close to a bottom edge
thereof. A side of the water inlet duct is provided with a
recovered water guide mouth. The water inlet duct is provided with
a water inlet tube extending into the barrel body close to the
bottom of the barrel body. A side of the water outlet duct is
provided with a vapor guide mouth. The faucet includes an outer
tube and an inner tube in the outer tube. The vapor box is fixedly
disposed on top of the heating barrel unit. The backflow connecting
tube of the first guide opening of the vapor box is connected to
the recovered water guide mouth of the water inlet duct of the
heating barrel unit. The check valve connecting tube of the second
guide opening is connected to the vapor guide mouth of the water
outlet duct. The water outlet duct of the heating barrel unit is
connected with the inner tube of the faucet. By the characteristic
that the specific gravity of cold water is greater than that of hot
water, when the cold water is guided from the water inlet duct into
the barrel body of the heating barrel unit and heated by operating
the heating controller, the hot water and vapor after heating are
stored at the upper part of the barrel body. The vapor and
condensed water are guided to the water collection trough and the
accommodation chamber of the vapor box from the recovered water
guide mouth of the water inlet duct via the backflow connecting
tube. The vapor is guided from the check valve connecting tube of
the second guide opening of the vapor box to the vapor guide mouth
of the water outlet duct, and then guided out from the water outlet
duct to the inner tube of the faucet, preventing the accumulation
of the vapor from generating biogas. The check valve connecting
tube only guides out the vapor and restrains backflow of the
condensed water. The vapor is guided out from the inner tube of the
faucet, preventing the outer tube from generating heat. When the
cold water is guided from the water inlet duct into the barrel body
of the heating barrel unit, the recovered water guide mouth of the
water inlet duct generates siphonage, allowing the condensed water
in the water collection trough and the accommodation chamber of the
vapor box to be siphoned to the recovered water guide mouth of the
water inlet duct and flow back into the barrel body of the heating
barrel unit, preventing the waste of a water resource. After the
condensed water of the water collection trough of the vapor box
flows back, the float balls in the float ball seat descend relative
to the float ball limit grooves, and the float balls abut against
the check rings provided in the guide holes so that the vapor box
is in a vacuum state to prevent the presence of air when the hot
water is guided out from the water outlet duct, such that the hot
water is in the form of a forward flow rather than a diffuse flow
to prevent the user from being scalded. Besides, the water inlet
duct and the water outlet duct are disposed on the top side of the
barrel body of the heating barrel unit, preventing water seepage.
The present invention is safe for use and able to prevent
leaks.

23 of the heating barrel unit 20 is connected with the inner tube
32 of the faucet 30. By the characteristic that the specific
gravity of cold water is greater than that of hot water, when the
cold water is guided from the water inlet duct 22 into the barrel
body 21 of the heating barrel unit 20 and heated by operating the
heating controller 24, the hot water and vapor after heating are
stored at the upper part of the barrel body 21. The vapor and
condensed water are guided to the water collection trough 130 and
the accommodation chamber 13 of the vapor box 10 from the recovered
water guide mouth 220 of the water inlet duct 22 via the backflow

ball limit grooves 131A, and the float balls 131D abut against the
check rings 131C provided in the guide holes 131B so that the vapor
box 10 is in a vacuum state, referring to FIG. 3, to prevent the
presence of air when the hot water is guided out from the water
outlet duct 23, such that the hot water is in the form of a forward
flow rather than a diffuse flow to prevent the user from being
scalded. Besides, the water inlet duct 22 and the water outlet duct
23 are disposed on the top side of the barrel body 21 of the
heating barrel unit 20, preventing water seepage. The present
invention is safe for use and able to prevent leaks.
[0019] Although particular embodiments of the present invention
