Detailed Description
The present invention is illustrated by the following examples, but the present invention is not limited to these examples. Modifications of the embodiments of the utility model, or equivalent substitutions for parts of technical features without departing from the spirit of the utility model, should be included in the scope of the claims of the utility model.
Referring to fig. 1, the present embodiment provides a micro-bubble water generating apparatus, which is applied to a water heater, and includes a gas water control valve 1, a three-way valve 2, and a controller 7. The air-water control valve 1 comprises a valve body 11 and an electromagnetic valve 12, wherein the valve body 11 is provided with a main water path 111 and an air inlet 112, the main water path 111 comprises a water inlet section and a water outlet section which are communicated, the water inlet section is communicated with a water source, and two opposite ends of the air inlet 112 are respectively communicated with the atmosphere and the water outlet section. The electromagnetic valve 12 is arranged on the valve body 11 and used for conducting or blocking the water inlet section. Therefore, the main water channel 111 and the air inlet 112 are integrated on the same valve body 11, and the electromagnetic valve 12 for controlling the conduction or the blockage of the main water channel 111 is additionally arranged on the valve body 11, so that the air inlet and the water inlet are integrated into a whole, the whole structure is simple and compact, and the device can be freely switched between the water inlet and the air inlet.
The three-way valve 2 has a water inlet 201, a water outlet 202 and a water outlet 203, the water inlet 201 is connected to the water outlet, the opposite ends of the water outlet 202 are connected to the water inlet 201 and the water consumption point, respectively, the water outlet 203 is connected to the water inlet 201 and a water collection area, which can be a sewer or a water storage tank, respectively. The controller 7 is electrically connected with the electromagnetic valve 12 and the three-way valve 2 respectively and is used for controlling the working states of the electromagnetic valve 12 and the three-way valve 2 according to the working mode of the water heater.
Referring to fig. 2-4, the water heater has at least a normal shower mode, a microbubble standby mode, a microbubble charging mode, and a microbubble operating mode. Referring to fig. 1-2, when the water heater enters the ordinary shower mode, the controller 7 opens the solenoid valve 12, and controls the water inlet 201 of the three-way valve 2 to conduct the water outlet 202, and the external water flows from the main water path 111 to the water inlet 201, and then flows out from the water outlet 202, during which, since the water pressure inside the valve body 11 is positive, the external air cannot be sucked into the valve body 11 through the air inlet 112, thereby ensuring that the micro bubble water is not generated in the ordinary shower mode.
Referring to fig. 3, when the water heater enters the microbubble aeration mode, the controller 7 first closes the electromagnetic valve 12 to cut off the water inlet of the main water path 111 in time; then, the water inlet 201 of the three-way valve 2 is controlled to conduct the water outlet 203, so that the water stored between the three-way valve 2 and the water outlet section of the main water channel 111 is automatically discharged to the water collecting area under the action of gravity. During the drainage process, a large negative pressure is formed between the three-way valve 2 and the valve body 11, so that the external air is sucked into the water outlet section of the main water channel 111 through the air inlet 112, and the areas of the water outlet section and the water inlet 201 are inflated. When the drainage time reaches a time threshold value, the water inlet 201 of the three-way valve 2 is controlled to be communicated with the water outlet 202, then the electromagnetic valve 12 is opened, the water heater is switched to a micro-bubble standby mode, at the moment, the water consumption point has no water demand, so that water and air cannot flow out from the water outlet 202, and as the electromagnetic valve 12 is opened again, part of water source is instantly sprayed into the area between the water outlet section and the water inlet 201, and the air in the area is further compressed to be dissolved into water to form low-concentration micro-bubble water. Therefore, through the cooperation of the electromagnetic valve 12 and the three-way valve 2, the purposes of reliably feeding air and manufacturing micro-bubble water without an air pump and a water pump are achieved, and energy consumption, noise and product cost are effectively reduced.
Referring to fig. 4, when the user needs to use the micro-bubble water, the user opens the water consumption point of the communication water consumption outlet 202, the water heater is switched from the micro-bubble standby mode to the micro-bubble operation mode, at this time, the pre-prepared micro-bubble water flows from the water consumption outlet 202 to the water consumption point, the waiting time is greatly shortened, and the user experience is improved. Meanwhile, an external water source flows from the main water path 111 to the water inlet 201, newly-entered water contacts with air filled in the area in advance and starts to dissolve air, micro-bubble water is continuously formed, and micro-bubble water is continuously produced within a period of time. Therefore, the automatic gravity drainage mode is adopted for pre-inflation, so that micro bubble water can be quickly discharged when the micro bubble operation mode is switched, the waiting time is greatly shortened, and the user experience is improved.
Referring to fig. 1, in the present embodiment, the main waterway 111 is vertically arranged and the air inlet 112 is transversely arranged. The valve body 11 is also provided with a mounting port 113 positioned between the water inlet section and the water outlet section, and the water inlet section is communicated with the water outlet section through the mounting port 113. The solenoid valve 12 is preferably a normally open type pilot operated solenoid valve, which is disposed at the installation port 113 and is used to open or close a passage between the water inlet section and the water outlet section, so as to save electric power.
Specifically, a partition part 114 is fixedly arranged in the water inlet section, a movable end of the partition part 114 extends into the mounting port 113 and divides an inlet of the mounting port 113 into an upper water passage port and a lower water passage port, wherein two opposite ends of the upper water passage port are respectively communicated with the water inlet ends of the water inlet section and the lower water passage port, and the water outlet end of the lower water passage port is communicated with the water outlet section. The electromagnetic valve 12 is used for conducting or blocking the upper water through opening and/or the lower water through opening. Thus, the electromagnetic valve 12 controls the opening and closing of the upper water passage port and/or the lower water passage port, and the main water passage 111 can be controlled to switch between the water intake and the water intake cutoff.
In other embodiments, the mounting port 113 may be disposed near the water inlet section, and the mounting port 113 is connected to only the water inlet section, and at this time, the electromagnetic valve 12 is used to open or close the water inlet section.
Referring to fig. 1, in the present embodiment, the air water control valve 1 includes a check valve 13, and the check valve 13 is disposed at the air inlet 112 for making the air inlet 112 communicate with the main waterway in a one-way manner, so that the internal water can be prevented from overflowing through the air inlet 112.
Referring to fig. 1, in the present embodiment, the three-way valve 2 includes a three-way joint 21 and a drain valve 22, and the three-way joint 21 has a water inlet 201, a water use outlet 202, and a drain opening 203. The drain valve 22 is preferably a normally closed type pilot operated solenoid valve, which is provided on the drain port 203 and electrically connected to the controller 7 for opening or closing the drain port 203, in order to facilitate power saving. Therefore, the water outlet 202 and the water inlet 201 are in a normal open state, at the moment, whether the water is discharged from the water outlet 202 is related to the water using condition of a water using point, a water valve does not need to be additionally arranged at the water outlet 202, and the cost is favorably reduced.
In other embodiments, the three-way valve 2 may further include a water outlet control valve disposed on the water outlet 202 and electrically connected to the controller 7 for controlling the water outlet on-off state of the water outlet 202 so that the water outlet 202 is not interfered when the water pressure fluctuation occurs at the water use point.
In other embodiments, the three-way valve 2 may be designed to include a three-way joint 21 and a valve core, the three-way joint 21 has a water inlet 201, a water use outlet 202 and a water discharge port 203, and the valve core is disposed in the three-way joint 21 and electrically connected to the controller 7 for selectively connecting the water inlet 201 to the water use outlet 202 or the water discharge port 203.
Referring to fig. 1, further, the device further comprises a dissolved air tank 3, and the water inlet 201 is communicated with the water outlet section through the dissolved air tank 3. Therefore, the dissolved air tank 3 is additionally arranged between the water inlet 201 and the water outlet section, so that the air storage capacity during single pre-inflation is improved, and a certain amount of micro-bubble water can be produced after the water heater is inflated every time. In the present embodiment, the volume of the dissolved air tank 3 is preferably larger than 1L.
Further, the device also comprises a flow guide disc 4, wherein the flow guide disc 4 is arranged in the dissolved air tank 3 and used for uniformly mixing tap water and air so as to ensure that the air is more easily dissolved into the water to form micro-bubble water. Specifically, after the micro-bubble water is fully mixed with the air in the dissolved air tank 3 under the action of the flow guide disc 4, micro-bubble water with the gas-liquid mixing ratio of about 1% -3% can be formed, and the requirements of users on sterilization, deep cleaning and the like can be better met.
Referring to fig. 2-4, the present embodiment also provides a water heater including a micro-bubble water generating device as described above, an internal water pipe 5, and a flow rate detecting device 6 electrically connected to the controller 7. The main water channel 111 is communicated with a water source through an inner water pipe 5. The flow rate detection device 6 is disposed on the inner water pipe 5 or between the inner water pipe 5 and the main water passage 111, and is configured to detect an inflow rate of the main water passage 111. In this embodiment, the flow detection device 6 is disposed on the inner water pipe 5 and located at the water inlet front end of the heat exchanger of the water heater. The micro-bubble water generating device is arranged at the water inlet rear end of a heat exchanger of the water heater so as to avoid abnormal sound caused by boiling of the generated micro-bubble water in the heat exchanger.
When a user presses a microbubble function key on the control panel 8 of the water heater, the water heater is switched from a common bathing mode to a microbubble mode, and the microbubble mode comprises a microbubble inflation mode, a microbubble standby mode and a microbubble operation mode.
In the microbubble aeration mode, the electromagnetic valve 12 is closed to intercept the inflow of water to the main water path 11, and the drain valve 22 is opened to drain the accumulated water in the dissolved air tank 3. In this mode, if the inflow detected by the flow detector 6 is greater than the start-up flow of the water heater (typically 2.5L/min), it is determined that the electromagnetic valve 12 does not completely block the inflow of the main water path 11, and the external water source flows into the dissolved air tank 3 and is discharged to the sewer along with the drainage port. At this time, the controller 7 closes the drain valve 22 and reports an alarm waterway fault on the control panel 8 of the water heater; the solenoid valve 12 is then reopened to switch the water heater to normal shower mode.
And after the dissolved air tank 3 is completely inflated, the water heater is switched to a micro-bubble standby mode. In the microbubble standby mode, the controller 7 records the reopening time of the electromagnetic valve 12, after the reopening time of the electromagnetic valve 12 is about 2-5 s, if the inflow water flow detected by the flow detection device 6 is larger than the starting flow, the controller 7 judges that a user opens the hot water faucet to use hot water, the controller 7 opens a gas control valve of the water heater to start and ignite, switches to the microbubble operation mode, and meanwhile, the controller 7 starts to record the accumulated microbubble water amount. Therefore, by means of the delayed starting ignition mode, the phenomenon that the electromagnetic valve 12 is opened again and water is sprayed into the dissolved air tank 3 instantly can be avoided, and the flow detection device 6 generates a large water flow signal to cause false starting.
In the microbubble operation mode, if the water inflow rate detected by the flow detection device 6 is smaller than the starting-up flow rate, the controller 7 closes the gas control valve, shuts down the gas control valve, switches to the microbubble standby mode, and suspends statistics of accumulated microbubble water amount if the water supply rate is judged to be that the user has shut down the water supply.
In the microbubble standby mode, the controller 7 judges that the accumulated microbubble water amount is smaller than the program single-tank microbubble water amount, the flow detection device 6 detects that the inflow water amount is larger than the startup flow, and judges that the user restarts heating water, the controller 7 opens the gas control valve, starts up and ignites, switches back to the microbubble operation mode, and continues to accumulate the microbubble water amount.
In this embodiment, after the water heater is switched from the microbubble operating mode to the microbubble standby mode, the controller 7 determines whether the accumulated amount of microbubble water is greater than or equal to the program amount of single-tank microbubble water, and if not, controls the water heater to maintain the microbubble standby mode. If the result shows that a little air remains in the dissolved air tank 3 and the micro-bubble water with sufficient concentration cannot be output, the controller 7 clears the accumulated micro-bubble water amount, controls the water heater to switch to the micro-bubble inflation mode, automatically inflates the dissolved air tank 3 in a gravity drainage mode, and ensures that the micro-bubble water with sufficient concentration can be output when water is reused.
Alternatively, the programmed single-tank microbubble water volume may be a fixed value or set by a parameter setting mode of the control panel 8, or the programmed single-tank microbubble water volume may be taken according to the volume of the dissolved air tank 3, and if the volume of the dissolved air tank 3 is 1L, the programmed single-tank microbubble water volume is preferably 100L.
In this embodiment, the drain valve 22 is opened to drain water for the programmed target drain time, and it is determined that the dissolved air tank 3 is filled with air. Optionally, the programmed target drainage time may be a fixed value, or the programmed target drainage time is set by a parameter setting mode of the control panel 8, or the programmed target drainage time is a value according to the volume of the dissolved air tank 3 or the actually measured drainage time, for example, when the volume of the dissolved air tank 3 is 1L, the drainage time is about 10 to 20 s.
What has been described above are merely some embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the utility model.
