A fourth aspect of the invention proposes a readable storage medium.

A fifth aspect of the present invention provides a water treatment apparatus.

In view of this, a first aspect of the present invention provides a control method of a water treatment apparatus including a water supply apparatus including: detecting whether the water supply device is started abnormally; stopping power supply to the water supply device based on the condition that the starting abnormality of the water supply device is detected, wherein the driving voltage at the moment of the starting abnormality of the water supply device is the first driving voltage; adjusting the driving voltage to the adjusted driving voltage; after the first preset time, recovering power supply to the water supply device, and driving the water supply device to work by the second driving voltage; the above-mentioned process is repeated until the water supply device is started up normally or the second driving voltage is greater than the preset voltage value, and the first driving voltage and the second driving voltage are different.

In this technical scheme, water treatment facilities includes instant heating type water dispenser, and instant heating type water dispenser includes water inlet pipeline, instant heating module, water outlet pipeline and water supply installation, and wherein, water inlet pipeline and water outlet pipeline are connected respectively to instant heating module, and water supply installation sets up in water inlet pipeline side, and water supply installation can pump cold water to instant heating module through water inlet pipeline after the electricity, heats the back to cold water through instant heating module, exports hot water. The water flow of the output hot water is related to the operation of the water supply device, the water supply device is selected as a water pump, and the temperature of the output hot water is related to the operation of the instant heating module.

Because a certain starting moment is needed in the starting process of the water supply device to realize rotation, the starting moment is different under different working conditions. For example: in the case of scaling of the water supply, a large moment is required to drive the water supply to operate. The output torque of the water supply device is correlated with the drive voltage input to the water supply device.

In the prior art, the starting voltage of the water supply device is usually calibrated before delivery, and when the water supply device starts to operate, the driving voltage calibrated before delivery is input to the water supply device. Along with the long-time operation of the water supply device, the water supply device may have abnormal conditions such as scaling, and the water supply device cannot operate under the driving of the calibrated driving voltage, namely, the water supply device is in a starting abnormal state, so that the water outlet function of the water treatment device is invalid, and at the moment, if the instant heating module performs heating, the instant heating module or other elements are damaged.

In view of the above problems, the present invention controls the input of a first driving voltage to the water supply device during the start-up of the water supply device when the water treatment device is in operation, detects whether the water supply device is in a start-up abnormal state, and immediately stops the input of the driving voltage to the water supply device when the water supply device is detected to be in the start-up abnormal state, thereby controlling the water supply device to stop operation. When it is detected that the water supply device is not in the abnormal starting state, the driving voltage is continuously input to the water supply device.

When the water supply device is in a starting abnormal state, the driving voltage of the water supply device is adjusted, specifically, the first driving voltage of the water supply device in the starting abnormal state is adjusted to the second driving voltage. And when the operation of the water supply device is stopped for a first preset time, controlling the water supply device to resume power supply according to the second driving voltage. After the water supply device is stopped for a first preset time, the water supply device can be ensured to be completely stationary, and the water supply device is controlled to resume power supply at the moment, so that the instantaneous moment of the water supply device can be improved, and the possibility of starting the water supply device normally is improved. After the water supply device is powered according to the second driving voltage, the process of detecting whether the water supply device is in a starting abnormal state and adjusting the driving voltage in the starting abnormal state of the water supply device is repeated until the water supply device is in a starting normal state or until the second driving voltage is larger than a preset voltage value. The first predetermined time may have a value in the range of 100 milliseconds to 500 milliseconds, optionally 200 milliseconds.

Wherein, in the process of adjusting the driving voltage of the water supply device, if the water supply device is restored to the starting normal state, the driving voltage of the water supply device does not need to be adjusted again. The preset voltage value is the maximum voltage value of the safe operation of the water supply device, and if the driving voltage of the water supply device is continuously increased after the driving voltage of the water supply device reaches the preset voltage value, the operation failure of the water supply device can be caused, so that the driving voltage of the water supply device is stopped being regulated after the driving voltage reaches the preset voltage value.

According to the invention, when the water supply device of the water treatment device is in the starting abnormal state, the water supply device is stopped and the driving voltage is regulated until the water supply device is in the starting normal state, so that the water supply device is secondarily started and remedied in the starting abnormal state of the water supply device, the water outlet efficiency of the water treatment device is ensured, the running reliability and stability of the water treatment device are improved, and the driving voltage of the water treatment device is stopped to be continuously regulated under the condition that the regulated second driving voltage reaches the preset voltage value, and the running safety of the water treatment device is ensured.

Specifically, the preset voltage value is a maximum voltage value for safe operation of the water supply device, and if the adjusted second driving voltage is greater than the preset voltage value, it is determined that if the water supply device is operated at the second driving voltage greater than the preset voltage value, an operation failure may be caused. Therefore, under the condition that the adjusted second driving voltage is larger than the preset voltage value, and the water supply device is still in a starting abnormal state according to the first driving voltage before adjustment, the water supply device is judged to be unable to be started normally, the water treatment device is controlled to stop, and the running safety of the water treatment device is ensured.

wherein V is ₁ For the second driving voltage, V ₀ For the first driving voltage, n is a preset adjustment value.

wherein V is ₁ For the second driving voltage, V ₀ And m is a preset adjustment coefficient for the first driving voltage.
