separately provided to enable the steam to flow according to a preset air duct, which
requires independently providing the air duct and a component for driving the steam
to flow, thereby increasing complexity of the air conditioner. In addition, the steam
generating device is disposed in an air conditioning device, and thus is inconvenient
to disassemble, and maintenance difficulty may be increased during maintenance of
the steam generating device, thereby affecting maintenance efficiency. Further, the

DETAILED DESCRIPTION
[0035] Reference will be made in detail to embodiments of the present application, and the
examples of the embodiments are illustrated in the drawings, wherein the same or similar
elements and the elements having same or similar functions are denoted by like reference
numerals throughout the descriptions. The embodiments described herein with reference
to drawings are illustrative, and merely used to explain the present application.
The embodiments shall not be construed to limit the present application.
[0036] A steam generating device 800 according to an embodiment of the present application
will be described below with reference to Figs. 1 to 28.
[0037] As shown in Figs. 1 to 28, the steam generating device 800 according to the embodiment
of the present application is suitable for generating steam to supply the steam to
an air conditioning device 700, and includes: a housing 810 suitable for being mounted
on a suspended ceiling, a water tank assembly 820, a water supplementing electromagnetic
valve, a heating assembly 830, a steam valve 8294, a ballcock 870, and a water level
detector 840. The water tank assembly 820 is provided in the housing 810, and has
a steam outlet 821, an air pressure adjustment port 8293 and a water inlet 822 for
supplying water into the water tank assembly 820, and the water inlet 822 is in communication
with a water source. The "water source" herein may refer to tap water or tap water
provided with a purification device. The heating assembly 830 is provided in the water
tank assembly 820, and the steam generated by a heating process of the heating assembly
830 is suitable for being discharged from the steam outlet 821. The steam valve 8294
is provided at the air pressure adjustment port 8293, and may control communication
or disconnection of the air pressure adjustment port 8293. It should be noted that
the steam valve 8294 may be connected with a controller, and when water is required
to be supplemented to the water tank assembly 820, the controller controls the steam
valve 8294 to be opened, such that a pressure in the water tank assembly 820 is close
to the atmospheric pressure, thereby further ensuring that water quickly flows into
the water tank assembly 820. When water is not required to be replenished to the water
tank assembly 820, the controller controls the steam valve 8294 to be closed. The
ballcock 870 is provided in the water tank assembly 820, and configured to control
on-off of the water inlet 822.
[0038] It should be noted that the steam outlet 821 may be provided near a top of the water
tank assembly 820, the water inlet 822 may be in communication with the water source
through a water inlet pipe, and water in the water source may flow into the water
tank assembly 820 through the water inlet 822. The heating assembly 830 is provided
in the water tank assembly 820, and may be disposed near a bottom of the water tank
assembly 820, and may heat water in the water tank assembly 820 into steam, and the
steam in the water tank assembly 820 generated by the heating process of the heating
assembly 830 flows to the air conditioning device 700 under the driving action of
an air pressure. The water level detector 840 is provided in the water tank assembly
820, and configured to detect a water level in a water tank.
[0039] The steam outlet 821 of the steam generating device 800 may be in communication with
an air outlet 900 of the air conditioning device 700 through a pipeline. When the
steam is required to be supplied to the air conditioning device 700, the controller
controls the steam generating device 800 to operate, the heating assembly 830 heats
the water in the water tank assembly 820, the water forms the steam in the heating
process, the steam is located above a water surface in the water tank assembly 820,
the air pressure above the water surface in the water tank assembly 820 is gradually
increased along with an increase of the steam, and the steam flows into the air conditioning
device 700 from the steam outlet 821 under the action of the air pressure. Since the
water in the steam generating device 800 is gradually reduced in the evaporation process,
when detecting that the water in the water tank assembly 820 is reduced to a predetermined
value, the water level detector 840 may send a signal to the controller, and the controller
may control the water inlet 822 to be opened, such that the water in the water source
flows into the water tank assembly 820. Such an arrangement may omit the working step
of manually adding water into the steam generating device 800, and the steam generating
device 800 is more convenient to use, thus improving a satisfaction degree of a user.
[0040] As shown in Fig. 14, when the steam generating device 800 works, the water in the
water tank assembly 820 is gradually converted into the steam, the liquid level of
the water in the water tank assembly 820 drops, and when the liquid level of the water
in the water tank assembly 820 is lower than the scale line c, the ballcock 870 opens
the water inlet 822, such that the water flows into the water tank assembly 820 from
the water inlet 822; such an arrangement may omit the working step of manually adding
water into the steam generating device 800, and the steam generating device 800 is
more convenient to use, thus improving the satisfaction degree of the user. The arrangement
of the ballcock 870 may keep the liquid level inside the water tank assembly 820 equal
to a height of the scale line c, thereby ensuring that enough water exists in the
water tank assembly 820.
[0041] Meanwhile, the steam generating device 800 may be provided outside the air conditioning
device 700, and thus convenient to disassemble, and a maintenance difficulty may be
decreased during maintenance of the steam generating device 800, thereby increasing
maintenance efficiency. Meanwhile, the steam generating device 800 is more convenient
to assemble, thus increasing assembly efficiency.
[0042] Thus, with cooperation of the housing 810, the water tank assembly 820, the heating
assembly 830 and the water level detector 840, water is not required to be manually
added into the steam generating device 800, and the steam generating device 800 is
more convenient to use; the steam generating device 800 may be provided outside the
air conditioning device 700, which may improve dismounting and mounting convenience
of the steam generating device 800, thereby improving a dismounting and mounting efficiency
of the steam generating device 800.
[0043] In some embodiments of the present application, as shown in Figs. 27 and 28, the
ballcock 870 may include: a connecting piece 871, a baffle 872 and a float ball 873.
The connecting piece 871 runs through the water inlet 822, a water flowing channel
is formed in the connecting piece 871, and an outer circumferential wall of the connecting
piece 871 is sealingly connected with an inner circumferential wall of the water inlet
822, thus preventing the water in the water tank assembly 820 from flowing out from
a position between the connecting piece 871 and the water inlet 822. The baffle 872
is pivotally connected with the connecting piece 871. The float ball 873 is connected
with the baffle 872, and drives the baffle 872 to open or close the water flowing
channel under the driving action of buoyancy of water. When the liquid level of the
water in the water tank assembly 820 is lower than the scale line c, the float ball
873 rotates downwards and drives the baffle 872 to open the water flowing channel,
such that the water flows into the water tank assembly 820, and when the liquid level
of the water in the water tank assembly 820 is flush with the scale line c, the float
ball 873 drives the baffle 872 to close the water flowing channel, such that the water
is unable to flow into the water tank assembly 820, and thus, the liquid level in
the water tank assembly 820 is flush with the scale line c.
[0044] In some embodiments of the present application, the baffle 872 and the float ball
873 are connected by a connecting rod 874, the baffle 872 has a central plane, a rotation
axis of the baffle 872 is located in the central plane, and an acute included angle
is formed between a central axis of the float ball 873 and the central plane. Such
an arrangement enables the float ball 873 to drive the baffle 872 to open or close
the water flow channel more easily, thus guaranteeing a working reliability of the
ballcock 870.
[0045] In some embodiments of the present application, as shown in Fig. 17, a water flowing
detection device 880 may be provided at the water inlet 822, and may detect whether
water flows through the water inlet 822. When the steam generating device 800 operates
normally, the water flowing detection device 880 does not operate. When the steam
generating device 800 is in a standby non-operation state or an operation state, continuous
water flowing signals (determined according to time) of the water flowing detection
device 880 indicate that a leakage occurs at a certain position of the steam generating
device 800.
[0046] In some embodiments of the present application, as shown in Fig. 18, a normally open
water-inlet electromagnetic valve 890 is provided at the water inlet 822, and the
normally open water-inlet electromagnetic valve 890 is normally open when powered
off and closed when powered on. When the water flowing detection device 880 detects
that a leakage occurs at a certain position of the steam generating device 800, the
controller may control the normally open water-inlet electromagnetic valve 890 to
be closed, so as to ensure that water is unable to flow into the steam generating
device 800 from the water inlet 822, thereby ensuring that water does not continuously
leak.
[0047] In some embodiments of the present application, the steam generating device 800 may
further include an alarm device, the alarm device may be electrically connected with
the controller, and when a leakage occurs at a certain position of the steam generating
device 800, the alarm device may send an alarm signal which may be a sound or a light
flash, so as to better prompt the user that a leakage occurs at a certain position
of the steam generating device 800.
[0048] In some embodiments of the present application, as shown in Figs. 3 to 7, the steam
generating device 800 may further include a normally closed water-inlet electromagnetic
valve 850, the normally closed water-inlet electromagnetic valve 850 may be connected
with the controller, and the controller may control the water-inlet normally closed
electromagnetic valve 850 to be opened and closed. Specifically, when the water level
detector 840 detects that the water level in the water tank assembly 820 is lower
than a water-supplementing water line a, the water level detector 840 sends a signal
to the controller, and then, the controller controls the normally closed water-inlet
electromagnetic valve 850 to be opened, such that water flows into the water tank
assembly 820, and when the water level in the water tank assembly 820 rises to a water-supplementing
stopping water line b, the water level detector 840 sends a signal to the controller,
and then, the controller controls the normally closed water-inlet electromagnetic
valve 850 to be closed, so as to stop replenishing water into the water tank assembly
820. Such an arrangement may achieve the working purpose of automatically controlling
water to be supplemented into the water tank assembly 820, and ensure that there exists
water stored in the water tank assembly 820 at any time, thereby guaranteeing the
working reliability of the steam generating device 800.
[0049] In some embodiments of the present application, as shown in Figs. 3 to 7, the water
tank assembly 820 may further have a drainage port 823, the drainage port 823 may
be provided with a drainage valve 824, and the drainage valve 824 is configured to
control on-off of the drainage port 823. When the water in the water tank assembly
820 is required to be drained out of the water tank assembly 820, the drainage valve
824 may be controlled to be opened, and then, the water in the water tank assembly
820 is drained out of the water tank assembly 820 from the drainage port 823. When
water is required to be stored in the water tank assembly 820, the drainage valve
824 is controlled to be closed, such that the water in the water tank assembly 820
may be prevented from flowing out of the water tank assembly 820, thereby preventing
the water in the water tank assembly 820 from flowing out of the water tank assembly
820.
[0050] In some embodiments of the present application, the heating assembly 830 may be configured
as an electric heating element which has a high working efficiency and a good reliability,
such that the water in the water tank assembly 820 may form steam fast, thus improving
the working efficiency of the steam generating device 800, and also further improving
the working reliability of the steam generating device 800.
[0051] In some embodiments of the present application, the electric heating element may
be configured as a PTC thermistor which has a quick temperature rise, such that during
operation of the steam generating device 800, a rate of forming the steam from the
water in the water tank assembly 820 may be increased, thereby further increasing
a working efficiency of the steam generating device 800. The PTC thermistor may be
used in water and is not prone to damage, thus prolonging a service life of the electric
heating element.
[0052] In some embodiments of the present application, a plurality of electric heating elements
may be provided, and the plurality of electric heating elements may be simultaneously
arranged in the water tank assembly 820, so as to further increase the rate of forming
the steam from the water in the water tank assembly 820, thereby further improving
the working efficiency of the steam generating device 800. When one of the plurality
of electric heating elements malfunctions, the other electric heating elements may
operate normally, thereby further guaranteeing the working reliability of the steam
generating device 800.
[0053] In some embodiments of the present application, as shown in Fig. 5, the water tank
assembly 820 may include a main water tank 825 having a heating cavity 826 therein,
both the water inlet 822 and the steam outlet 821 may be provided in the main water
tank 825, and the heating assembly 830 may be provided in the main water tank 825.
It should be noted that the water tank assembly 820 has an integrated structure, the
steam outlet 821 may be disposed near a top of the main water tank 825, the heating
assembly 830 may be disposed near a bottom of the main water tank 825, and when water
is required to be replenished into the main water tank 825, the controller controls
the normally closed water-inlet electromagnetic valve 850 to be opened, water may
flow into the heating cavity 826 through the water inlet pipe and the water inlet
822, and after completion of the water replenishment of the main water tank 825, the
controller controls the normally closed water-inlet electromagnetic valve 850 to be
closed. When the steam is required to be supplied to the air conditioning device 700,
the controller controls the heating assembly 830 to work, and the heating assembly
830 may rapidly heat the water in the heating cavity 826 into steam.
[0054] In some embodiments of the present application, as shown in Fig. 3, the water tank
assembly 820 may include: a working water tank 827 and a water supplementing tank
828. The working water tank 827 has the drainage port 823, and the working water tank
827 and the water supplementing tank 828 do not operate at the same time. The working
water tank 827 may have the heating cavity 826 and the steam outlet 821; that is,
the steam outlet 821 may be provided in the working water tank 827, the water supplementing
tank 828 may be in communication with the working water tank 827 through a communicating
pipe 829, and the water supplementing tank 828 may have the water inlet 822; that
is, the water inlet 822 is provided in the water supplementing tank 828. Water may
flow into the water supplementing tank 828 through the water inlet 822 and stored
therein, and when the working water tank 827 is required to be supplemented with water,
the water in the water supplementing tank 828 may flow into the working water tank
827 through the communicating pipe 829, thereby ensuring that water is stored in the
working water tank 827 at all times. The water inlet 822 is provided with the normally
closed water-inlet electromagnetic valve 850, when the water in the water supplementing
tank 828 is lower than the water-supplementing water line a, the controller controls
the normally closed water-inlet electromagnetic valve 850 to be opened, such that
water flows into the water supplementing tank 828 from the water inlet 822, and when
the water in the water supplementing tank 828 rises to the water-supplementing stopping
water line b, the controller controls the normally closed water-inlet electromagnetic
valve 850 to be closed, so as to stop supplementing water into the water supplementing
tank 828; such an arrangement may ensure that water is stored in the water supplementing
tank 828, and may avoid the condition that no water is stored in the working water
tank 827, thereby avoiding a dry heating condition of the heating assembly 830, and
then prolonging a service life of the heating assembly 830. The water supplementing
electromagnetic valve (i.e., electromagnetic valve 8292) is provided in the communicating
pipe 829 and configured to control communication or disconnection thereof.
[0055] It should be noted that the steam outlet 821 may be provided near a top of the working
water tank 820, the water inlet 822 may be in communication with the water source
through the water inlet pipe, and the water in the water source may flow into the
water supplementing tank 820 through the water inlet 822. The heating assembly 830
is provided in the working water tank 827, may be disposed near a bottom of the working
water tank 827, and may heat the water in the working water tank 827 into steam, and
the steam in the working water tank 827 generated by the heating process of the heating
assembly 830 flows to the air conditioning device 700 under the driving action of
the air pressure. The water level detector 840 is provided in the water tank assembly
820, and configured to detect the water level in the water tank.
[0056] In some embodiments of the present application, the communicating pipe 829 may be
configured as a U-pipe. After the working water tank 827 is in communication with
the water supplementing tank 828 through the U-pipe, a communicating vessel may be
formed by the structure of the working water tank 827 and the water supplementing
tank 828, and during the operation of the steam generating device 800, the water in
the working water tank 827 is reduced gradually, the water level in the water supplementing
tank 828 is then higher than the water level in the working water tank 827, and under
the action of a pressure difference, the water in the water supplementing tank 828
may be pressed into the working water tank 827, thereby achieving the work purpose
of supplementing water into the working water tank 827.
[0057] The heating assembly 830 is provided in the working water tank 827, the steam generated
by the heating process of the heating assembly 830 is suitable for being discharged
from the steam outlet 821, and the steam in the working water tank 827 flows to the
air conditioning device 700 under the driving action of the air pressure. The ballcock
870 is provided in the water supplementing tank 828, and configured to control the
on-off of the water inlet 822.
[0058] As shown in Fig. 4, according to another embodiment of the present application, the
water tank assembly 820 may include: a working water tank 827 and a water supplementing
tank 828. The working water tank 827 may have the heating cavity 826, the steam outlet
821 may be provided in the working water tank 827, and the water supplementing tank
828 may be in communication with the working water tank 827 through a communicating
pipe 829, such that a communicating vessel may be formed by the structure of the working
water tank 827 and the water supplementing tank 828; the water inlet 822 is provided
in the water supplementing tank 828. An upper end of the working water tank 827 is
in communication with an upper end of the water supplementing tank 828, thus ensuring
that the working water tank 827 and the water supplementing tank 828 have equal pressures,
so as to avoid that the excessive pressure in the working water tank 827 presses the
water back to the water supplementing tank 828.
[0059] In some embodiments of the present application, as shown in Fig. 16, a one-way valve
may be provided at the U-pipe, to enable fluid to flow only from the water supplementing
tank 828 to the working water tank 827, such that the fluid in the working water tank
827 may be prevented from flowing to the water supplementing tank 828, and thus, sufficient
fluid may be stored in the working water tank 827.
[0060] In some embodiments of the present application, the working water tank 827 may have
the air pressure adjustment port 8293 which may be in communication with the heating
cavity 826. It should be noted that, when the working water tank 827 is required to
be supplemented with water, the air pressure adjustment port 8293 is opened, the air
pressure in the heating cavity 826 is reduced rapidly, such that the pressure in the
heating cavity 826 is rapidly close to the atmospheric pressure, thereby ensuring
that the water in the water supplementing tank 828 rapidly flows into the working
water tank 827, and further completing the water supplementing work of the working
water tank 827.
[0061] In some embodiments of the present application, the steam valve 8294 may be provided
at the air pressure adjustment port 8293, and connected with the controller, so as
to better control opening or closing of the air pressure adjustment port 8293 to be
opened or closed, and when the working water tank 827 is required to be supplemented
with water, the controller controls the steam valve 8294 to be opened, such that the
pressure in the heating cavity 826 is quickly close to the atmospheric pressure, thereby
further ensuring that the water in the water supplementing tank 828 quickly flows
into the working water tank 827. When the working water tank 827 is not required to
be supplemented with water, the controller controls the steam valve 8294 to be closed.
[0062] It should be noted that, when the steam generating device 800 is used for the first
time or works for a period of time, and the working water tank 827 is required to
be supplemented with water, the water supplementing tank 828 may supplement water
into the working water tank 827 through the communicating pipe 829. When the U-pipe
is connected between the water supplementing tank 828 and the working water tank 827,
the water in the water supplementing tank 828 may be replenished into the working
water tank 827 using a communicating vessel principle, and when the water level in
the water supplementing tank 828 drops, and the water level detector 840 detects that
the water supplementing tank 828 is required to be supplemented with water, the normally
closed water-inlet electromagnetic valve 850 is opened to replenish water into the
water supplementing tank 828; since the communicating vessel is constructed by the
water supplementing tank 828 and the working water tank 827, the two water tanks have
flush liquid levels, and when the water level in the water supplementing tank 828
reaches a certain height, the water level detector 840 sends an electric signal to
control the normally closed water-inlet electromagnetic valve 850 to be closed, thus
stopping supplementing water into the water supplementing tank 828.
[0063] When the water supplementing tank 828 and the working water tank 827 have sufficient
water, and steam is required to be generated, the heating assembly 830 may be started
to heat the water in the working water tank 827 to generate the steam; in the heating
process of the heating assembly 830, the air pressure in the working water tank 827
is increased gradually, and since the communicating pipe 829 is provided with the
one-way valve, the fluid is unable to flow to the water supplementing tank 828 from
the working water tank 827, and at this point, under the effect of the air pressure
in the working water tank 827, the water supplementing tank 828 does not replenish
water to the working water tank 827; that is, a pressure generated by a height difference
of liquid columns in the water supplementing tank 828 and the working water tank 827
is equal to the pressure in the working water tank 827, and at this point, the water
supplementing tank 828 does not replenish water to the working water tank 827.
[0064] After the heating assembly 830 performs the heating operation for a period of time,
and when the amount of water around the heating assembly 830 is not enough, a little
amount of steam or no steam is generated inside the working water tank 827, and at
this point, if the steam is required to be generated continuously, the working water
tank 827 is required to be supplemented with water; that is, only when the air pressure
in the working water tank 827 is equal to the air pressure in the water supplementing
tank 828, the water supplementing tank 828 may supplement water to the working water
tank 827. The air pressure in the working water tank 827 and the water supplementing
tank 828 may be balanced using the following two ways: 1) since the heating assembly
830 stops performing the heating operation, a temperature in the working water tank
827 is decreased gradually, and the remaining steam in the working water tank 827
condenses gradually, such that the air pressure in the working water tank 827 is decreased
gradually, and when the air pressure in the working water tank 827 is decreased to
a certain degree, the water in the water supplementing tank 828 may flow into the
working water tank 827 using the communicating vessel principle; 2) in order to quickly
balance the pressure in the working water tank 827 and the water supplementing tank
828, the air pressure adjustment port 8293 may be provided in the working water tank
827, the steam valve 8294 may be provided at the air pressure adjustment port 8293,
and when the pressure in the working water tank 827 and the water supplementing tank
828 is required to be balanced, the steam valve 8294 is opened to quickly restore
the pressure in the working water tank 827 to the atmospheric pressure, and then,
the pressure in the working water tank 827 may be balanced with the pressure in the
water supplementing tank 828.
[0065] In some embodiments of the present application, as shown in Fig. 6, a plurality of
working water tanks 827 may be provided, and the plurality of working water tanks
827 operate together in a unit time, which may increase an amount of the steam generated

is in communication with at least one working water tank 827. It should be noted that
each water supplementing tank 828 may be in communication with one or plural working
water tanks 827. When each water supplementing tank 828 may be in communication with
one working water tank 827, the water supplementing tanks 828 are in one-to-one correspondence
with the working water tanks 827; that is, one water supplementing tank 828 is in
communication with only one working water tank 827, or one water supplementing tank
828 replenishes water to only one working water tank 827.
[0067] It should be noted that the steam generating device 800 may be in communication with

with the working water tank 827 using the communicating vessel principle, and the
upper end of the water supplementing tank 828 is in communication with the upper end
of the working water tank 827. Such an arrangement may ensure that the pressure in
the water supplementing tank 828 is equal to the pressure in the working water tank
827, and may prevent the water in the working water tank 827 from being pressed into
the water supplementing tank 828 when the pressure in the working water tank 827 is
too large. The water inlet 822 of each water supplementing tank 828 may be provided
with the normally closed water-inlet electromagnetic valve 850, each water supplementing
tank 828 is provided therein with the water level detector 840, and when the water

line a, the normally closed water-inlet electromagnetic valve 850 is opened, and water
may flow into the water supplementing tank 828 through the main water inlet pipe,
the water inlet pipe, and the water inlet 822 in sequence, and when the water level
rises to the water-supplementing stopping water line b, the normally closed water-inlet
electromagnetic valve 850 is closed to stop supplementing water to the water supplementing

device 800 may be in communication with the water source through the main water inlet
pipe, and the plurality of water inlet pipes may be provided at the main water inlet

water inlet pipe, the water inlet pipe, and the water inlet 822 in sequence, and when
the water level rises to the water-supplementing stopping water line b, the normally
closed water-inlet electromagnetic valve 850 is closed to stop supplementing water
to the main water tank 825.
