Detailed Description
At water catalyst or electrochemical sterilization field, there is the TDS restriction problem always, when quality of water TDS is on the high side, equipment can't use, and cleaning equipment can't use when TDS is too high or low among the correlation technique, has influenced cleaning equipment's use and application range. For this reason, can utilize the detection to quality of water TDS to confirm the working method of cleaning equipment (whether operate and how to operate in order to adapt TDS), TDS detection mode of relevant art can not satisfy the requirement of TDS detection precision and efficiency in the cleaning equipment. Therefore, the invention provides a TDS measuring method of a cleaning device, which is used for measuring the equivalent TDS of an electrolyzer based on electrochemical reaction, and whether the electrolyzer is suitable for operation or the operation mode is judged by using the equivalent TDS, so that the operation stability of the cleaning device can be effectively improved.
The equivalent TDS is a result measured by the electrolytic device based on electrochemical reaction, and is related to but not identical with the TDS of the water quality, namely, the equivalent TDS can reflect the TDS of the water quality, but the equivalent TDS is not necessarily the TDS of the water quality. Of course, the present invention may also use the water TDS to determine the power supply mode, for example, setting the equivalent TDS to be the same as the water TDS.
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 drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
Referring to fig. 1, a TDS measuring method of a cleaning apparatus according to a first aspect of the present invention, the cleaning apparatus including an electrolyzer, for measuring an electrochemical reaction-based equivalent TDS of the electrolyzer, the measuring method including: when the electrolytic device is initially electrified, constant-current power is supplied to the electrolytic device, electrochemical reaction and the like can be generated in the running process of the electrolytic device, and therefore cleaning is achieved. In addition, when power is supplied to the electrolyzer, the current of the electrolyzer is attenuated by the electrochemical reaction or the like performed by the electrolyzer. Therefore, in the process of outputting constant current to the electrolysis device, the highest current value of the electrolysis device at the initial electrifying time and the attenuation current value after the preset electrifying time are obtained, and the current values of the electrolysis device are different in attenuation conditions for different water qualities, so that the equivalent TDS can be determined according to the preset time, the highest current value and the attenuation current value, and the detection precision and the detection efficiency are effectively improved.
According to the TDS measuring method of the cleaning equipment, the equivalent TDS is detected according to the current change of the electrolysis device, and the detection precision of the equivalent TDS is improved by combining the actual working state of the electrolysis device. In addition, the detection efficiency can be improved by the change of the current of the electrolysis device.
In addition, because the electrolytic device generates electrochemical reaction and the like in the operation process, the measurement result of the TDS of the water quality and the like can be influenced, the state of the electrolytic device is determined by using the equivalent TDS, the electrochemical reaction and the like in the electrolytic process are considered, and the control precision can be effectively improved.
Specifically, constant current can be supplied to the electrolysis device, the current value of the electrolysis device can be attenuated in the power supply process, and even when other media are adhered to the surface of the electrolysis device, the equivalent TDS can be obtained according to the current attenuation condition of the electrolysis device, so that the measurement accuracy of the equivalent TDS can be effectively improved. In addition, the structure of the cleaning equipment can be effectively simplified and the cost of the cleaning equipment is reduced because the detection module of the equivalent TDS is not required to be additionally arranged. Moreover, the detection efficiency of the equivalent TDS can be improved.
In addition, since the current value attenuation of the electrolyzer varies among electrolyzers of different materials, sizes, etc., the algorithm for determining the equivalent TDS from the current value varies among electrolyzers of different materials, sizes, etc. To this end, the present invention further provides algorithms for determining the equivalent TDS based on the predetermined time period, the maximum current value, and the decaying current value.
FIG. 9 is a graph showing the change in current value of the electrolyzer when the initial constant current value was outputted to the electrolyzer. The equivalent TDS can be calculated from the change in current value of the electrolyzer.
Optionally, determining the equivalent TDS according to the predetermined time period, the maximum current value, and the decaying current value includes: and determining the equivalent TDS according to a formula that the ratio of the sum of the maximum current value and the attenuation current value to the preset time length is multiplied by a first fixed coefficient. In other words, the equivalent TDS is determined according to the formula equivalent TDS of C1 (y1+ y2)/t, where C1 is a first fixed coefficient, y1 is the maximum current value of the electrolyzer during the initial power-on, t is the predetermined time period, and y2 is the decaying current value of the electrolyzer after the power-on for the predetermined time period.
In addition, the invention can also determine the equivalent TDS according to the real-time effective current of the electrolysis device. For example, during the operation of the electrolysis device, the real-time effective current of the electrolysis device is acquired, and the equivalent TDS is determined according to the real-time effective current. In other words, the real-time effective current value of the electrolyzer is obtained, and the equivalent TDS is determined according to the formula equivalent TDS — C2 × I, where C2 is the second fixed coefficient and I is the real-time effective current value. Particularly, when the electrolytic device is in stable working process, the current value of the electrolytic device is stable in a period of time, so that the current equivalent TDS can be accurately calculated by acquiring the real-time effective current value of the electrolytic device, the detection efficiency is improved, and the working efficiency and the stability of the cleaning equipment are improved.
In addition, the C1 and the C2 can be calculated according to actual use conditions, and the fixing coefficients C1 and C2 are different for electrolytic devices with different materials and sizes.
In addition, as shown in fig. 2 and fig. 6, during the electrolysis process of the electrolysis device, the change of the electrolysis device is different between the initial power-on and the working process of the electrolysis device, so that different equivalent TDS measurement modes are adopted for the initial power-on and the working process of the electrolysis device respectively. Specifically, the measurement method further includes: when the cleaning equipment is initially electrified, outputting constant current to the electrolysis device, acquiring a highest current value of the electrolysis device at the initial electrification and an attenuation current value after the preset electrification time, and determining the equivalent TDS according to the preset time, the highest current value and the attenuation current value; and in the working process of the cleaning equipment, acquiring the real-time effective current of the electrolytic device, and determining the equivalent TDS according to the real-time effective current. Thereby to under the operating condition of difference, adopt different equivalent TDS measurement methods to improve equivalent TDS's detection precision and detection efficiency.
Optionally, acquiring a real-time effective current of an electrolyzer during a working mode of the cleaning equipment and determining the equivalent TDS according to the real-time effective current, where the method includes: and determining the equivalent TDS according to a formula, wherein the equivalent TDS is equal to the product of the real-time effective current and a second fixed coefficient.
In addition, the equivalent TDS can also be determined by using the formula equivalent TDS ═ C1 ═ (y1+ y2)/t during the operation of the cleaning equipment.
The invention uses a variable power module and a flexible control system, summarizes a set of unique control method through deep research and analysis of electrode materials, improves the tolerance of water quality in a large range, and can work normally almost in full equivalent TDS.
In addition, with reference to fig. 3 to fig. 6, the present invention further provides a method for controlling a cleaning apparatus, which can utilize the equivalent TDS determined by the TDS measuring method, and control the cleaning apparatus according to the detected equivalent TDS.
Specifically, the control method includes: obtain electrolytic device's equivalent TDS based on electrochemical reaction, through the detection to equivalent TDS, can judge the power supply mode who is applicable to current equivalent TDS, and then can be according to power module's power supply mode is confirmed to equivalent TDS, and control power module with power supply mode is right electrolytic device power supply, this moment, the power module output power supply mode adaptation in current equivalent TDS to can improve cleaning equipment's stability and cleaning efficiency effectively, in addition, improved cleaning equipment's equivalent TDS application scope, convenient to use. Wherein, the equivalent TDS can be obtained according to the TDS measuring method. According to equivalent TDS, adjust the power supply mode to electrolytic device to reduce because too big or the undersize of equivalent TDS leads to the unable normal work's of cleaning equipment problem. Moreover, in the use of cleaning equipment, along with the continuation of cleaning process, equivalent TDS can change, can adjust the power supply mode to electrolytic device according to equivalent TDS in this application, can be when equivalent TDS changes, adjust the power supply to electrolytic device fast to improve the stability in the cleaning equipment working process, improve clean efficiency and clean effect effectively.
In addition, the invention mainly determines the equivalent TDS in the electrochemical reaction process of the electrolyzer, and the equivalent TDS is not completely the same as the TDS value in the cleaning equipment.
Specifically, in order to effectively improve the operation stability of the electrolyzer, the power supply modes required by the electrolyzer are different when the equivalent TDS is in different gears, so that the power supply mode of the electrolyzer can be determined according to the gear in which the equivalent TDS is located. Optionally, as shown in fig. 4, determining the power supply mode of the power supply module according to the equivalent TDS includes: if the equivalent TDS is in a low gear, determining that the power supply mode is a direct current constant current mode; if the equivalent TDS is in the middle gear, determining that the power supply mode is a direct current constant current mode or a sine constant current mode; and if the equivalent TDS is in a high level, determining that the power supply mode is a triangular wave constant current mode. The low gear, the middle gear and the high gear are relatively speaking, generally, the equivalent TDS of the low gear is lower than that of the middle gear, and the equivalent TDS of the high gear is greater than that of the middle gear. And through carrying out the gear with equivalent TDS and dividing to confirm suitable power supply mode to the equivalent TDS of different gears, can improve cleaning equipment's work efficiency and stability, and improve the equivalent TDS's that cleaning equipment is suitable for the scope.
Optionally, the low gear is a range of 0 to 80mg/L of the equivalent TDS, the medium gear is a range of 80 to 300mg/L of the equivalent TDS, and the high gear is a range of 300 to 1000mg/L of the equivalent TDS. Of course, in the actual use process, the power supply modes applicable to the electrolysis device are different under different equivalent TDS due to the difference in the size, shape, material and the like of the pole pieces of the electrolysis device, so that the ranges of the low gear, the middle gear and the high gear are adjusted according to the actual use condition. And the equivalent TDS of the high gear is not lower than that of the middle gear, and the equivalent TDS of the middle gear is not lower than that of the low gear.
Among them, the common current forms are three types, namely, constant (direct current), pulsating current and alternating current. Wherein, the current is constant direct current (direct current), and the magnitude and the direction of the current are not changed along with time. On a graph with current as ordinate and time as abscissa, it is a straight line parallel to the abscissa axis. ② pulsating current, the magnitude of the current changes with time, but the direction does not change. For example, the output current of the dc generator and the rectified current of the ac generator are both pulsating currents, and the values thereof are both above the horizontal axis in the graph. And thirdly, alternating current (alternating current), the magnitude and direction of which are periodically changed along with time. Such as sawtooth current, rectangular current, sine wave current, and triangular current, whose values are periodically above or below the horizontal axis on the graph. The direct current constant current mode in the invention can be constant direct current, the sine constant current mode can be alternating current, the triangular wave constant current mode can be pulse current, and the pulse waveform is triangular wave.
Optionally, the control method of the present invention further includes adjusting the amplitude, the frequency, the waveform, and the like of the current power supply mode according to the equivalent TDS when the equivalent TDS is in the high gear. For example, if the equivalent TDS is in the high range, the slope of the triangular wave constant current mode when the equivalent TDS is high is higher than or equal to the slope of the triangular wave constant current mode when the equivalent TDS is low; and/or the peak value of the triangular wave constant current mode when the equivalent TDS is high is less than or equal to the peak value of the triangular wave constant current mode when the equivalent TDS is low; and/or the period of the triangular wave constant current mode when the equivalent TDS is high is shorter than or equal to the period of the triangular wave constant current mode when the equivalent TDS is low. Or, as the equivalent TDS increases, the slope of the triangular wave constant current mode provided by the power module increases, the peak value decreases, and the period is shortened, thereby further improving the electrolytic stability when the equivalent TDS is high, and in addition, when the equivalent TDS is in a high gear, one or more of the slope, the peak value, and the period of the triangular wave constant current mode can be adjusted along with the change of the equivalent TDS.
Optionally, the cleaning equipment can further comprise a bubble generator for providing bubbles into the electrolysis device, and the bubbles can be conveyed into the electrolysis device through the bubble generator, so that the cleaning efficiency and the cleaning effect of the cleaning equipment are effectively improved. The bubble generator may have a certain influence on the operation of the electrolyzer, and particularly when the equivalent TDS is in the middle gear, the mode for supplying power to the electrolyzer needs to be determined according to the operation state of the bubble generator. Specifically, as shown in fig. 5, if the equivalent TDS is in the middle gear: and if the bubble generator runs, determining that the direct power supply mode is the current power supply mode, and if the bubble generator stops, determining that the power supply mode is the sine constant current mode. Therefore, according to the working state of the bubble generator, the working stability of the electrolysis device can be improved, and the cleaning effect and efficiency of the cleaning equipment can be effectively improved by the simultaneous action of the bubble generator and the electrolysis device.
In addition, in a cleaning device without a bubble generator, when the equivalent TDS is in a middle gear, a sinusoidal constant current mode can be directly adopted. Of course, when the equivalent TDS is in a low gear, a high gear, or the like, parameters of the power supply mode of the electrolyzer or the current power supply mode may also be adjusted according to the operating state of the bubble generator.
The computer readable storage medium according to the second aspect of the invention has stored thereon a TDS measurement program of a cleaning device, which when executed by a processor implements a TDS measurement method as described above.
According to the computer-readable storage medium provided by the embodiment of the invention, the equivalent TDS is detected according to the current change of the electrolysis device, so that the detection efficiency of the equivalent TDS can be improved. In addition, the detection precision of the equivalent TDS can be improved by the electrifying time and the current attenuation of the electrolysis device.
According to a third aspect of the invention, a washing device comprises a memory, a processor and a TDS measurement program of the washing device stored on the memory and executable on the processor, the processor implementing the TDS measurement method as described above when executing the TDS measurement program of the washing device.
According to the cleaning equipment provided by the embodiment of the invention, the equivalent TDS is detected according to the current change of the electrolysis device, so that the detection efficiency of the equivalent TDS can be improved. In addition, the detection precision of the equivalent TDS can be improved by the electrifying time and the current attenuation of the electrolysis device. Therefore, the cleaning mode of the cleaning equipment can be determined according to the detection result of the equivalent TDS.
As shown in fig. 7, the TDS measuring device according to the fourth aspect of the present invention for measuring an electrochemical reaction-based equivalent TDS of an electrolyzer, includes: the electrolytic device comprises an electrolytic device, a current sensor and a main controller, wherein the current sensor is connected with the electrolytic device and is used for detecting the current value of the electrolytic device; the main controller is connected with the electrolysis device and the current sensor, and is used for supplying power to the electrolysis device at a constant current when the electrolysis device is initially electrified, acquiring the highest current value of the electrolysis device at the initial electrification and the attenuation current value of the electrolysis device after the electrolysis device is electrified for a preset time, and determining the equivalent TDS according to the preset time, the highest current value and the attenuation current value.
According to the TDS measuring device provided by the embodiment of the invention, the equivalent TDS is detected according to the current change of the electrolysis device, so that the detection efficiency of the equivalent TDS can be improved. In addition, the detection precision of the equivalent TDS can be improved by the electrifying time and the current attenuation of the electrolysis device.
Specifically, a constant current can be supplied to the electrolyzer, and the current value of the electrolyzer attenuates during the power supply, and the attenuation of the current value of the electrolyzer is related to the characteristics of the electrolyzer, so that even when other media adhere to the surface of the electrolyzer, the equivalent TDS can be obtained according to the current attenuation of the electrolyzer, and the measurement accuracy of the equivalent TDS can be effectively improved. In addition, the structure of the cleaning equipment can be effectively simplified and the cost of the cleaning equipment is reduced because the detection module of the equivalent TDS is not required to be additionally arranged. Moreover, the detection efficiency of the equivalent TDS can be improved.
In addition, since the current value attenuation of the electrolyzer varies among electrolyzers of different materials, sizes, etc., the algorithm for determining the equivalent TDS from the current value varies among electrolyzers of different materials, sizes, etc.
Optionally, the main controller is further configured to calculate an equivalent TDS by multiplying a ratio of a formula equivalent TDS equal to the sum of the maximum current value and the decaying current value to the predetermined time period by a first fixed coefficient when determining the equivalent TDS according to the predetermined time period, the maximum current value, and the decaying current value. In other words, the equivalent TDS is determined according to the formula equivalent TDS of C1 (y1+ y2)/t, where C1 is a first fixed coefficient, y1 is the maximum current value of the electrolyzer during the initial power-on, t is the predetermined time period, and y2 is the decaying current value of the electrolyzer after the power-on for the predetermined time period.
In addition, the invention can also determine the equivalent TDS according to the real-time effective current of the electrolysis device. For example, a real-time effective current of an electrolyzer is obtained and the equivalent TDS is determined from the real-time effective current. In other words, during the operation of the electrolysis device, the real-time effective current value of the electrolysis device is obtained, and the equivalent TDS is determined according to the formula equivalent TDS — C2 ×, where C2 is the second fixed coefficient and I is the real-time effective current value. Particularly, when the electrolytic device is in stable working process, the current value of the electrolytic device is stable in a period of time, so that the current equivalent TDS can be accurately calculated by acquiring the real-time effective current value of the electrolytic device, the detection efficiency is improved, and the working efficiency and the stability of the cleaning equipment are improved.
In addition, the C1 and the C2 can be calculated according to actual use conditions, and the fixing coefficients C1 and C2 are different for electrolytic devices with different materials and sizes.
In addition, in the electrolytic process of the electrolytic device, the change condition of the electrolytic device is different in the initial power-on and working processes of the electrolytic device, so different equivalent TDS measurement modes are respectively adopted in the initial power-on and working processes of the electrolytic device. In particular, the master is further configured to: when the cleaning equipment is initially electrified, outputting constant current to the electrolysis device, acquiring the highest current value of the electrolysis device at the initial electrification and the attenuation current value of the electrolysis device after the preset electrification time, and determining the equivalent TDS according to the preset time, the highest current value and the attenuation current value; and under the working mode of the cleaning equipment, acquiring the real-time effective current of the electrolytic device, and determining the equivalent TDS according to the real-time effective current. Thereby to under the operating condition of difference, adopt different equivalent TDS measurement methods to improve equivalent TDS's detection precision and detection efficiency.
