The application provides a method for intelligently adjusting the rotating speed of a pressure stabilizing pump based on a noise value, which realizes that the noise value of a water purifier is controlled within a design range. The water purifier comprises a detection device, a controller and a pressure stabilizing pump adjusting device. As shown in the figure, the noise value is detected by the sound level meter and is compared with the set theoretical noise value, and then the rotating speed of the motor is adjusted by the voltage stabilizing pump adjusting device to adjust the noise value, so that the noise reduction is realized.
The noise and the water pressure of the water purifier are detected through the detection device, and the actual detection noise value and the water pressure data are obtained and sent to the controller. The type of the water pressure data is not exclusive, and may specifically include water inlet pressure data and water pressure data before the membrane. The controller prestores water pressure gear data, the water pressure gear data comprise a plurality of pressure value ranges, and each pressure value range corresponds to a corresponding noise value threshold or a noise value interval respectively. After actual water pressure data are collected, corresponding theoretical noise data can be determined by combining the stored water pressure gear data.
Further, after the actual water inlet pressure data and the water pressure data before the membrane are obtained, the controller firstly judges whether the water inlet pressure data is in a preset water inlet pressure range; and if so, comparing the water pressure data before the membrane with the water pressure gear data, determining the gear interval where the water pressure data before the membrane is located, and further determining the corresponding theoretical noise data. And then, the controller compares the water pressure data before the membrane with the theoretical noise data, if the water pressure data before the membrane is matched with the theoretical noise data, the actual noise of the water purifier is normal, the rotating speed of a pressure stabilizing pump of the water purifier does not need to be adjusted, if the rotating speed of the pressure stabilizing pump of the water purifier is not matched, the actual noise of the water purifier is overlarge, and the rotating speed of the pressure stabilizing pump of the water purifier needs to be adjusted to reduce the noise. In addition, if the water inlet pressure data is not in the water inlet pressure range, alarm prompt information is output.
When the theoretical noise data comprises a theoretical noise threshold, if the actual detection noise value is larger than the theoretical noise threshold, the actual detection noise value is not matched with the theoretical noise data; if the actual detected noise value is less than or equal to the theoretical noise threshold, the actual detected noise value matches the theoretical noise data. When the theoretical noise data includes a theoretical noise range, if the actual detection noise value is larger than the upper limit value of the theoretical noise range, the actual detection noise value is not matched with the theoretical noise data; and if the actual detection noise value is within the theoretical noise range, matching the actual detection noise value with the theoretical noise data.
When the actual detection noise value is not matched with the theoretical noise data, the controller controls the pressure stabilizing pump adjusting device to adjust the pressure stabilizing pump of the water purifier, the rotating speed of a motor of the pressure stabilizing pump is reduced, the noise is reduced, and the rotating speed of the pressure stabilizing pump is intelligently adjusted according to the noise value, so that the noise of the water purifier is controlled within a design range.
Specifically, as shown in fig. 3, the detection device comprises a sound level meter and a pressure monitor, the sound level meter is arranged on the body of the water purifier, and the pressure monitor is arranged in front of the water inlet and the reverse osmosis membrane filter element. A method for realizing intelligent control of noise logic by a water purifier through detecting a noise value and calculating a theoretical noise value set by a control module is disclosed, and as shown in figure 4, the method comprises the following specific steps:
(1) when the water purifier is in a water production state, the sound level meter automatically detects a noise value.
(2) The calculation control module is used for setting a plurality of pressure values, such as a low pressure value, a medium pressure value, a high pressure value and the like, wherein each pressure value corresponds to a corresponding noise value interval.
(3) Comparing the actual detection noise value with the theoretical noise value, and when the actual noise value is higher than the set theoretical noise value, responding by the regulator pump regulator to reduce the rotation speed of the motor and the noise value; when the actual noise value is equal to or lower than the set theoretical noise value, the regulator does not respond and maintains the original motor speed. The water inlet pressure of the general water purifier is 0.1-0.4MPa, when the water inlet pressure is insufficient or overhigh, the theoretical noise value cannot be calculated, and the controller gives an alarm prompt. And the rotating speed of the pressure stabilizing pump is intelligently adjusted according to the noise value, so that the noise of the water purifier is controlled within a design range.
The water purifier can comprise a simple system, sequentially passes through a front filter element, a reverse osmosis membrane filter element and a rear filter element, is supplemented with a pressure stabilizing pump and a control valve, and a controller board realizes the pure water function. The water purifier also comprises a complex system, such as a water purification system which sequentially passes through a preposed filter element, a reverse osmosis membrane filter element and a postposition filter element and is assisted by a pressure stabilizing pump, a control valve and a controller board to control the backflow of concentrated water and the backflow of pure water or the backflow of the concentrated water and the pure water.
