DETAILED DESCRIPTION

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.
A steam generating device 800 according to an embodiment of the present application will be described below with reference to Figs. 1 to 28.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.

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.
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.

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.

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.
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.
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.
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.
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.
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.

The water supplementing tank 828 is in communication 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.
