Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative and intended to explain the present invention and should not be construed as limiting the present invention.
The following describes a water purifier and a water outlet control system and method thereof according to embodiments of the present invention with reference to the accompanying drawings.
FIG. 1 is a schematic view of a water egress control system according to one embodiment of the present invention.
As shown in fig. 1, the present invention provides a water outlet control system 10 of a water purifier, wherein the water purifier includes an air inlet, a water inlet, and a water outlet, and the water outlet control system 10 includes an ejector 11, a gas mixing tank 12, a bubbler 13, an air inlet valve 14, a water level detection unit 15, and a control unit 16.
The water inlet end of the ejector 11 is communicated with the water inlet, the air inlet end of the ejector 11 is communicated with the air inlet, an air inlet valve 14 is arranged between the air inlet end of the ejector 11 and the air inlet, and the ejector 11 is configured to converge air flowing into the air inlet and water flowing into the water inlet end when the air inlet valve 14 is opened; an inlet of the air mixing tank 12 is communicated to an outlet of the ejector 11, and the air mixing tank 12 is configured to mix and dissolve the merged air and water to output a water-air mixture; an inlet of the bubbler 13 is communicated with an outlet of the gas mixing tank 12, an outlet of the bubbler 13 is communicated with a water outlet, and the bubbler 13 is configured to generate micro-bubble water according to the water-gas mixture; the water level detection section 15 is configured to detect the water level inside the gas-mixed tank 12; the control part 16 is connected to the water level detection part 15 and the air inlet valve 14, respectively, and the control part 16 is configured to control the air inlet valve 14 to open when the water purifier starts the micro-bubble water function, and control the air inlet valve 14 to close when the water level in the air mixing tank 12 is less than or equal to a first preset water level, and control the air inlet valve 14 to open until the water level in the air mixing tank 12 reaches a second preset water level, so that the micro-bubble water is stably output through the water outlet, wherein the second preset water level is greater than the first preset water level.
Specifically, in this embodiment, after the micro bubble water function of the water purifier is started, air is sucked into the ejector 11 from the air inlet, tap water flows into the ejector 11 from the water inlet, the tap water and the air are merged in the ejector 11 and are conveyed to the air mixing tank 12 through the outlet of the ejector 11, the air mixing tank 12 can convey the air and the tap water to the bubbler 13 after mixing, and the bubbler 13 can flow out micro bubble water from the water outlet for use by a user after performing pressure stabilization and release on the water-air mixture. However, if the water in the air mixing tank 12 is too little and the air is excessive, the micro bubble water flowing out of the water outlet sometimes generates air injection phenomenon, for example, when the water in the air mixing tank 12 does not reach one tenth of the volume of the air mixing tank, the air injection occurs at the water outlet, thereby greatly affecting the use of users.
Therefore, in this embodiment, a water level detection portion 15 is provided for detecting the water level of the gas mixing tank 12, and when the water level in the gas mixing tank 12 reaches a preset water level, the open/close state of the intake valve 14 is controlled by the control portion 16. Specifically, when the water level detecting portion 15 detects that the water level is less than or equal to the first preset water level, the air intake valve 14 is controlled to close, because the water amount in the air mixing tank 12 is less at this time, if air continues to be sucked, the air injection phenomenon may occur at the water outlet, and at this time, tap water still flows into the ejector 11 from the water inlet and then flows into the air mixing tank 12, so the water amount in the air mixing tank 12 is continuously accumulated, and when the water in the air mixing tank 12 reaches the second preset water level, the control portion 16 controls the air intake valve 14 to open the air intake valve, because the water amount in the air mixing tank 12 at this time can ensure that the water does not inject air, the air intake valve 14 can be opened to ensure that the water discharged from the water purifying machine is slightly-soaked water.
It should be noted that, in the case where the intake valve 14 is closed, since the amount of water in the air mixing tank 12 is continuously accumulated, the pressure in the air mixing tank 12 may be gradually increased, and further, in the case where both the amount of water and the pressure in the air mixing tank 12 satisfy the conditions, the water purifier may stably output the micro-bubble water.
In some embodiments of the present invention, as shown in fig. 2, the water level detection part includes a first water level sensor 151 and a second water level sensor 152, the first water level sensor 151 being disposed corresponding to a lower portion of the gas mixing tank 12, and the second water level sensor 152 being disposed corresponding to an upper portion of the gas mixing tank.
Specifically, as shown in fig. 1 and 2, the water level detection part 15 includes a first water level sensor 151 for detecting whether the water level in the gas mixing tank 12 is equal to or lower than a first preset water level, and a second water level sensor 152 for detecting whether the water level in the gas mixing tank 12 is greater than a second preset water level, wherein the first water level sensor 151 is disposed at a lower position of the gas mixing tank 12 and the second water level sensor 152 is disposed at an upper position of the gas mixing tank 12 because the second preset water level is greater than the first preset water level. In some specific embodiments, the first water level sensor is provided at 1/5 scale of the gas mixing tank, and the second water level sensor is provided at 4/5 scale of the gas mixing tank.
As shown in fig. 3, in some embodiments, the water outlet control system 10 of the water purifying machine further comprises a pressure reducing valve 17 disposed between the water inlet and the water inlet end of the ejector 11, and a pressure boosting pump 18 disposed between the outlet of the ejector 11 and the inlet of the gas mixing tank 12, wherein the pressure reducing valve 17 is matched with the ejector 11 to control the flow rate of the water flowing into the water inlet, and the pressure boosting pump 18 is matched with the ejector 11 to make the air and the water merged by the ejector fully mixed and dissolved in the gas mixing tank.
Specifically, the booster pump 18 in the present embodiment is disposed between the ejector 11 and the gas mixing tank 12, and is capable of pumping the water output from the ejector 11 and merged with the air into the gas mixing tank 12, and more specifically, the booster pump 18 can be used in cooperation with the ejector 11 to control the pipeline to generate negative pressure, so as to suck in the tap water and the air, for example, the booster pump 18 may be a piston type water pump, and the suction and the boosting of the water vapor are completed through the reciprocating motion of the internal piston, so as to generate the negative pressure. In order to increase the pumping capacity of the booster pump 18, the piston may be provided with a diaphragm, and the booster pump 18 may be mounted in such a manner that the pump head is placed vertically downward. It should be noted that, under the conditions that the self-suction force of the booster pump 18 is not less than 30Kpa, the water inlet pressure is 0.2MPa, and the water outlet pressure is 0.7MPa, the flow rate of the water flowing into the water inlet can be controlled to be not less than 2L/min.
It should be noted that, in order to generate the micro-bubble water continuously and stably, it is necessary to ensure that the water purifier can suck enough air, and the air suction capacity of the system is mainly determined by the booster pump 18, and after the specification of the booster pump 18 is selected, the air suction capacity of the water purifier is basically determined. Experiments can determine that the gas-liquid ratio is controlled to be between 1.5% and 2.5%, namely the ratio of the air suction volume to the water suction volume of the water purifier is between 1.5% and 2.5%, so that the water purifier can be ensured not to generate micro-bubble water, and experiments can know that the corresponding maximum flow rate of the water purifier is Q at the lowest gas-liquid ratio, in the specific embodiment, the maximum flow rate can be 2L/min, and in order to meet the condition that the gas-liquid ratio is not lower than the lowest gas-liquid ratio, inflow water can be throttled, so that the flow rate of a system cannot exceed the maximum flow rate Q at any water pressure. Therefore, in the present embodiment, a pressure reducing valve 17 is provided between the water inlet and the ejector 11, and the pressure of the inlet water can be reduced by the pressure reducing valve 17 when the pressure of the inlet water is high, so that the inlet water flow rate is controlled not to exceed the maximum flow rate Q.
In some embodiments, the inlet pressure and the outlet pressure of the pressure reducing valve satisfy the following conditions: p ═ kP 0 + C, where P is the outlet pressure of the pressure reducing valve, P 0 K and C are preset parameters for the inlet pressure of the pressure reducing valve.
Specifically, as shown in fig. 3, an inlet of the pressure reducing valve 17 is connected to a water inlet, and after the tap water flows into the pressure reducing valve 17 from the water inlet, pressure reduction control can be performed through the pressure reducing valve 17, more specifically, at a pressure P of the tap water 0 I.e. the inlet pressure of the pressure reducing valve 17 is P 0 In the case of (2), via the formula P ═ kP 0 The + C calculation yields the outlet pressure P of the pressure reducing valve 17. In addition, the formula P ═ kP 0 K and C in + C are both preset parameters, can be determined according to the specification parameters of the pressure reducing valve 17, and can also be determined through a large number of experiments, and both k and C are larger than zero.
It should be noted that, in the case where the intake water pressure is high, the control may be performed by the pressure reducing valve 17 so that the flow rate after the pressure reduction control by the pressure reducing valve 17 is not larger than the maximum flow rate Q, and if the intake water pressure is low, the flow rate may not exceed the maximum flow rate Q without the control by the pressure reducing valve 17, and then the intake water may be pressurized when it passes through the pressurizing pump 18 so that the air can be sufficiently dissolved in the tap water.
More specifically, in the air mixing tank 12, two factors affecting the dissolution of air into water are the air inflow and the pressure inside the air mixing tank, respectively, under the condition that the air flow is not changed, the larger the pressure inside the air mixing tank 12 is, the more the amount of air dissolved into water is, the better the microbubble effect is, while the larger the water inlet pressure is, the larger the pressure inside the air mixing tank 12 is, when the water inlet pressure is lower (e.g. lower than 0.05MPa), the lower the pressure inside the air mixing tank 12 is (e.g. lower than 0.15MPa), and at this time, the microbubble effect is poor. And because when the pressure in the gas mixing tank 12 is lower, the water level in the gas mixing tank 12 is lower generally, so need control admission valve 14 to close, and after admission valve 14 closes, booster pump 18 originally carries on the pressure boost to air and running water, after admission valve 14 closes, only need to carry on the pressure boost to the running water, because the flowrate of the running water is fixed after the relief pressure valve 17 reduces the pressure, so the booster pump 18 is under the same pressure boost effect, only carry on the pressure boost to the running water and the effect of the pressure boost to the running water and air at the same time is good, can improve the pressure in the gas mixing tank 12, and then the air in the gas mixing tank 12 can be fully dissolved in the water. That is, after the intake valve 14 is controlled to be closed, it is possible to increase the pressure of the air-mixed tank 12 while prohibiting air from entering the air-mixed tank 12, thereby simultaneously solving the problem of poor mixing effect of the effluent jet air and the air liquid. In some embodiments, the pressure within the gas mixture tank 12 ranges from 0.35 to 0.7MPa at the boost pressure of the booster pump 18.
In some embodiments of the present invention, as shown in fig. 4, the ejector 11 comprises a throat section located in the middle, the throat diameter of the waterway interface of the throat section is 1.8-2.0mm, the suction diameter of the airway interface of the throat section is 1.0-1.5mm, the expansion diameter of the outlet port of the throat section is 4.8mm, and the expansion angle is 5-7 °.
Specifically, referring to fig. 4, the ejector 11 is a three-way quick connector with a venturi structure, and as known from bernoulli's principle, negative pressure is generated when water flows through a throat section, so that air can be sucked from an air inlet under the action of atmospheric pressure. The middle port of the ejector 11 is an air path port, the straight-through port is a water path port, the throat diameter d1 is a key parameter, the size of the throat diameter d1 of the ejector 11 can be determined according to the maximum flow Q determined in the embodiment, and the throat diameter can be 1.8-2.0 mm.
