Description
Technical Field
The invention relates to the technical field of humidifiers, in particular to a control method of an electrode humidifier.
Background
In order to meet the technical requirements of electronic equipment on environmental constant temperature and humidity, an electrode humidifier is generally arranged in an air conditioner to humidify the environment. The electrode humidifier uses the water solution in the humidifying barrel as a conductive medium, and humidifies steam generated by heating the water solution through the electrode immersed in the water solution. In the process of evaporating the aqueous solution in the humidification barrel, the aqueous solution is gradually reduced, the concentration of a dielectric medium dissolved in the aqueous solution is continuously increased, and further the conductivity of the aqueous solution is continuously increased. However, the conductivity of the electrode humidifier to the aqueous solution is generally required to be in the range of 125-1250 muS/cm, and when the conductivity of the aqueous solution is too high, electric sparks are easily generated by discharging between electrodes, so that potential safety hazards exist.
In order to solve the potential safety hazard, a conventional solution is to periodically and automatically replace the aqueous solution in the humidification barrel, that is, after the humidifier is humidified and operated for a certain time, the water inlet electromagnetic valve and the water outlet electromagnetic valve of the humidification barrel are simultaneously opened for a set time, so that the old aqueous solution in the humidification barrel is discharged, and meanwhile, a fresh aqueous solution is injected, so that the replacement of the aqueous solution in the humidification barrel of the humidifier is realized, and the conductivity of the aqueous solution in the humidification barrel is reduced. This solution of periodically replacing the aqueous solution, although reducing the conductivity in the humidification tub to some extent, has the following problems. Firstly, the actual use environment of the humidifier has large water quality difference, different regions have different water quality conditions, and the timed water change cannot meet the requirements of different regions on different water qualities. In areas with poor water quality, the same water changing time leads to relatively low water changing frequency of the humidifier, and potential safety hazards are easy to generate; in areas with good water quality, the humidifier is frequently changed due to the same water changing time, and water resources are easily wasted. Secondly, the water supply pressure is different when each practical project is used, so the replacement rate of the water in the humidifying barrel is different in the same water injection time. In places with high water pressure, the water injection amount in the set time is large, so that the water solution in the humidifying barrel is excessively replaced, and the water in the humidifying barrel is easy to overflow to cause the fault of an air conditioning circuit; and in places with low water pressure, the water injection amount in the set time is small, the water solution replacement in the humidifying barrel is insufficient, and the operation of the humidifier is easy to be unstable to generate potential safety hazards.
Accordingly, there is a need in the art for a new control method of an electrode humidifier to solve the above problems.

The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
Referring to fig. 1, fig. 1 is a flow chart illustrating a control method of an electrode humidifier according to the present invention. As shown in fig. 1, in order to solve the problem of poor water exchange effect of the control method for regularly exchanging water for the electrode humidifier in the air conditioner of the existing machine room, the control method for the electrode humidifier mainly comprises the following steps:
s100, judging the size of the solution conductivity Sn of the water solution in the humidification barrel, for example, obtaining the solution conductivity Sn of the water solution in the humidification barrel by arranging a conductivity sensor in the humidification barrel, comparing the solution conductivity Sn with the maximum allowable conductivity Smax or the minimum allowable conductivity Smin, and judging the size of the solution conductivity Sn; wherein, the maximum allowable conductivity Smax and the minimum allowable conductivity Smin are general requirements of the electrode humidifier for the conductivity of the aqueous solution, and when the aqueous solution in the humidification barrel is between the maximum allowable conductivity Smax and the minimum allowable conductivity Smin, the humidification effect of the electrode humidifier is better and the operation is stable, for example, the maximum allowable conductivity Smax and the minimum allowable conductivity Smin can be 1250 μ S/cm and 125 μ S/cm respectively as described in the background art, and of course, the vertical direction can be adjusted correspondingly for different electrode humidifiers or water quality in different regions;
and S200, selectively replacing the aqueous solution in the humidification barrel or sending fault prompt information according to the magnitude of the solution conductivity Sn, for example, replacing the aqueous solution in the humidification barrel when the solution conductivity Sn is greater than the maximum allowable conductivity Smax, and sending fault prompt information when the solution conductivity Sn is less than the minimum allowable conductivity Smin.
Referring to fig. 2, fig. 2 is a schematic view illustrating a flow of determining whether to replace the water solution in the humidification cylinder in the control method of the electrode humidifier of the present invention. As shown in fig. 2, in a possible implementation, step S200 may further include:
s211, comparing the solution conductivity Sn with the maximum allowable conductivity Smax, for example, comparing the obtained solution conductivity Sn with 1250 muS/cm;
s212, if the solution conductivity Sn is greater than the maximum allowable conductivity Smax, further determining whether the influent conductivity Sz of the feedwater source is not greater than a first conductivity threshold S1, where the maximum allowable conductivity threshold Smax is greater than the first conductivity threshold S1, for example, again as Smax 1250 μ S/cm and Smin 125 μ S/cm, the first conductivity threshold may be S1-Smax 100 μ S/cm, when the solution conductivity is detected to be greater than 1250 μ S/cm, it is proved that the dielectric in the aqueous solution is too much, the aqueous solution needs to be replaced, otherwise, the electrode humidifier stability is reduced, and a safety hazard is easily caused, and at this time, the influent conductivity Sz of the feedwater source may be obtained by providing a conductivity sensor on the inlet pipe of the humidification tub, and compared with the first conductivity threshold S1 1150 μ S/cm, of course, the specific value of the first conductivity threshold S1 can be set and adjusted by those skilled in the art for different water qualities as long as the value is less than Smax, for example, the first conductivity threshold S1 can also be equal to Smax-200 or directly set to 800 μ S/cm, etc., and the setting of the value will directly affect the water change frequency and the water change speed;
s213, if the incoming water conductivity Sz is not greater than the first conductivity threshold S1, replacing the aqueous solution in the humidification barrel, for example, if the incoming water conductivity Sz is detected to be less than 1150 μ S/cm, it is proved that after the aqueous solution in the humidification barrel is completely or partially replaced by using the water supply source, the conductivity of the aqueous solution meets the water quality requirement of the electrode humidifier pair, and thus the aqueous solution in the humidification barrel can be replaced at this time.
From the above description, it can be seen that by judging the magnitude of the solution conductivity Sn, the control method of the present invention can know whether the aqueous solution in the humidification barrel reaches the replacement condition, and can replace the aqueous solution in the humidification barrel when the replacement condition is reached. By judging whether the incoming water conductivity Sz is not more than the first conductivity threshold value S1, the control method of the invention can also know whether the incoming water quality at this time meets the water quality requirement of the humidifier, and then replace the water solution in the humidification barrel when meeting the water quality requirement, thereby further improving the utilization rate of water resources and the stability of the humidifier, enabling the humidifier to adapt to the requirements of different water qualities, and thus operating in a stable conductivity range all the time.
Still taking the above data as an example, in a possible embodiment, if the intake water conductivity Sz is greater than the first conductivity threshold value S1, a fault notification message is issued, for example, when it is detected that the intake water conductivity Sz is greater than the first conductivity threshold value S1 ═ 1150 μ S/cm, then the conductivity of the water supply source is significantly high, that is, the water quality is hard, if the water solution in the humidification barrel is replaced at this time, not only the water in the humidification barrel needs to be completely replaced, but also the water solution is replaced again because the solution conductivity Sn reaches the maximum allowable conductivity x soon after the replacement, which causes extreme waste of water resources, so that the user can be informed that the water quality is hard by, for example, an audible and visual alarm or a display screen of an air conditioner, that the water softener needs to be added into the humidification barrel to soften the water solution in the humidification barrel, the conductivity of the water solution in the humidification barrel is reduced, and the problem that the humidification effect is poor due to frequent water change of the electrode humidifier is avoided.
Referring to fig. 3, fig. 3 is a schematic view of a flow of determining whether to send out a fault notification message in the control method of the electrode humidifier of the present invention, and in another possible implementation, step S200 further includes:
s221, comparing the solution conductivity Sn with the minimum allowable conductivity Smin, for example, comparing the obtained solution conductivity Sn with 125 mu S/cm;
s222, if the solution conductivity Sn is less than the minimum allowable conductivity Smin, controlling the fault prompting device to send out fault prompting information, wherein the fault prompting information is frequently generated when the humidifier is used for the first time or the water solution in the humidifier is drained for reuse due to maintenance or stopping use, when the inlet water conductivity Sz is detected to be less than the minimum allowable conductivity Smin, then the conductivity of the water supply source is significantly low, namely, the water quality is soft, if the electrode humidifier carries out humidification at the moment, the electrode humidifier is likely to fail to work due to low conductivity, therefore, the user can be informed that the water quality is soft by the audible and visual alarm of the audible and visual alarm or the display screen of the air conditioner, and a hard water agent (such as salt) needs to be added into the humidifying barrel to harden the water solution in the humidifying barrel, the conductivity of the water solution in the humidifying barrel is improved, and the problem that the electrode humidifier is poor in humidifying effect due to the fact that steam cannot be generated is avoided.
In a more preferred embodiment, before the step of further determining whether the incoming water conductivity Sz of the supply water source is not greater than the first conductivity threshold S1, the control method further includes:
the control water discharge electromagnetic valve is opened for a set time, for example, the set time may be several seconds, such as a short time of 1S, 3S or 5S, before the step of further determining whether the water inlet conductivity Sz of the water supply source is not greater than the first conductivity threshold S1, the detection precision of the water inlet conductivity may be significantly improved by first opening the water discharge electromagnetic valve for a short time to discharge the old water in the water inlet pipeline into the humidification bucket, and then detecting the conductivity of the new water in the water inlet pipeline, thereby improving the determination precision of the control method.
Referring to fig. 4, fig. 4 is a schematic flow chart illustrating the replacement of the aqueous solution in the humidification tub in the control method of the electrode humidifier of the present invention. As shown in fig. 4, still taking the above parameters as examples, in a preferred embodiment, the step S213 may further include the following steps:
s2131, controlling a water inlet electromagnetic valve of the humidifying barrel to be opened, for example, controlling the water inlet electromagnetic valve to be opened to add water into the humidifying barrel when the water inlet conductivity Sz is detected to be less than 1150 mu S/cm after the water inlet electromagnetic valve is opened for 3S;
s2132, while, before, or after the water inlet solenoid valve is opened, controlling the water discharge solenoid valve of the humidification barrel to open, preferably, while the water inlet solenoid valve is opened, controlling the water discharge solenoid valve to open, so that water addition and water discharge are performed simultaneously, and the water change efficiency is accelerated, and certainly, opening the water discharge solenoid valve before or after the water inlet solenoid valve is opened can also achieve the purpose of water change;
2133, further judging the magnitude of the solution conductivity Sn of the aqueous solution in the humidification barrel, for example, obtaining the solution conductivity Sn of the aqueous solution in the humidification barrel through a conductivity sensor and comparing the solution conductivity Sn with a set conductivity threshold value, so as to achieve the purpose of accurately controlling the opening and closing of the water inlet electromagnetic valve and the water outlet electromagnetic valve;
s2134, if the solution conductivity Sn is not greater than the second conductivity threshold S2, controlling the drainage solenoid valve to close, where Smax is 1250 μ S/cm, Sz is 500, and the second conductivity threshold may be S2 ═ Sz + (Smax-Sz)/2 ═ 500+ (1250-Sz)/2 is 875 μ S/cm, and when it is detected that the solution conductivity Sn reaches 875, closing the drainage solenoid valve, where the purpose is to determine that the solution conductivity Sn of the aqueous solution is less than the maximum allowable conductivity Smax by first closing the drainage solenoid valve when the solution conductivity Sn reaches S2, the humidifier is sufficiently operated, and continuing to add water only causes the solution conductivity to become low, and at this time, closing the drainage solenoid valve can save water resource and avoid waste of water resource, and the specific setting mode of S2 is not unique, and those skilled in the art can adjust the drainage based on the actual water quality, so that the arrangement of the S2 can enable the humidifier to achieve better water changing efficiency;
s2135, if the solution conductivity Sn is not greater than the third conductivity threshold S3, or if an electric signal of the high water level sensor is received, controlling the water inlet solenoid valve to close, wherein the second conductivity threshold S2 is greater than the third conductivity threshold S3, and still taking the above parameters as examples, the third conductivity threshold may be S3 ═ Sz + (Smax-Sz)/4 ═ 500+ (1250-, the working stability and the humidifying effect of the electrode humidifier are improved; and if the water inlet electromagnetic valve is closed when the electric signal of the high water level sensor is received, the faults such as circuit faults and the like caused by the overflow of the water solution in the humidification barrel can be avoided on the premise of ensuring the normal work of the humidifier, the specific setting mode of S3 is not unique, and the technical personnel in the field can adjust the water inlet electromagnetic valve based on the actual water quality so that the humidifier can achieve better water changing efficiency by the setting of S3.
Referring to fig. 5, a method for controlling the electrode humidifier of the present invention will be explained. Fig. 5 is a schematic structural diagram of an electrode humidifier in an air conditioner to which the control method of the present invention is applied.
