It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the prior art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
The control method of the water storage device provided by the embodiment of the invention is suitable for the control method of the water storage device of the water container, for example, a water dispenser and other household appliances needing to be added with water from the water container, and the control method is not particularly limited herein as long as the water container is arranged in the household appliance for adding water.
Fig. 1 schematically shows a flowchart of a control method of a water storage apparatus according to an embodiment of the present invention. Referring to fig. 1, the method for controlling a water storage device provided in the embodiment of the present invention specifically includes steps S11 to S14, as follows:
and S11, detecting the water level state value after the system is electrified and self-checked.
When the water storage device is in the water storage process, when the water level gradually rises until the water level is contacted with the probe, the probe is contacted with the water to conduct electricity, so that the detection of the water level in the water storage device can be realized. But actually, the water storage device is not full of water when the probe signal is detected, the top of the water storage device and the pipeline still have cavities, and the water storage device is usually set to continuously feed water for T seconds after the liquid level signal is detected so as to ensure that the water in the water storage device is full of water. Namely, the water storage device is divided into a water inlet stage when the liquid level is less than the probe and a water replenishing stage when water enters for T seconds after the liquid level signal is detected. The water level state value is whether the probe detects a liquid level signal or not, and if the probe does not detect the liquid level signal, the digital state value is recorded as 0; if the probe detects the liquid level signal, the digital status value is recorded as X.
The system power-on self-test specifically comprises the step of detecting a water level state value if a probe signal is detected after the system is powered on.
And S12, judging whether the water replenishing condition is met according to the detected water level state value.
And the water supplementing condition is that when the water level state value is 0, namely the water tank 4 is powered off in the water inlet stage, and the water supplementing stage is carried out for T seconds again. When the water level state value is X, the water storage device is indicated to be full of water, and water is not required to be supplemented continuously.
And S13, if the detected water level state value meets the water supplementing condition, determining water supplementing time according to the current water level state value.
If the water level state value is 0, water replenishing time is determined according to the current water level state, in the water storage process, when the probe detects a liquid level signal, namely after the water replenishing stage begins, 1 is added to the X value at intervals of set time, the X value is respectively 1, 2, 3 and 4 … … N, and after the water replenishing stage is carried out for the time threshold value, the water tank 4 state value X is the water full threshold value, the water inlet electromagnetic valve 1 is closed, and the water inlet stage is ended.
Example (c): according to the actual product condition, a water supplementing time threshold T of a certain product is determined to be 100 seconds, a water full threshold N is set to be 10, and a water level state value X is 0 when a probe signal is not detected. When the system detects a 3 signal of the liquid level probe, water is replenished, the value X is added by 1 every ten seconds, if the power failure condition occurs suddenly when the water replenishing process is carried out for 68 seconds, at the moment, X =6, the system is electrified again, then the probe signal is read to find that the water inlet stage is completed, the value X is read to be 6, the water replenishing is judged to be not completed, [ (1- (water level state value/water full threshold)) + water replenishing time threshold ] =40, and then the water replenishing is carried out for 40 seconds to ensure that the water storage is completed.
When the control system is powered on, firstly, self-checking is carried out, the state of the liquid level probe 3 is read, if no liquid level signal exists, water inlet operation is carried out, if the liquid level signal is detected, the state value of the water tank 4 is read, and if X = N, the water tank 4 is full of water. If X is not N, the water tank 4 is powered off in the water inlet stage, and the water replenishing stage is performed again for [ (1- (X/N)). times.T ] seconds.
And S14, water is supplemented according to the determined water supplementing time until the water is full.
And (5) supplementing water according to the water supplementing time determined in the step (S13) until the recorded water level state value X is N, and ending the water supplementing phase.
After the system is electrified, the system can not detect the probe signal, the water inlet electromagnetic valve 1 is opened, water starts to enter, and when the water level gradually rises to the height of the liquid level probe 3, the system continues to enter water for T seconds, and the water inlet electromagnetic valve 1 is closed. The water is supplied for T seconds to fill the top of the water tank 4 and the pipeline with water. The whole water storage process comprises a water inlet stage from water inlet to the stage that the probe detects a liquid level signal and a T-second water replenishing stage after the liquid level probe 3 is detected. The main solution is frequently watered and is led to the phenomenon of wasting the water resource.
In the water storage working process, the system detects whether the water inlet stage is finished or not through a probe signal, but an effective detection means is lacked for the water replenishing stage. In practical application, when the system is in a water replenishing stage after the probe signal is detected, the system is powered off at the moment. After the system is powered on again, the water outlet delay can be caused by the cavities in the water tank 4 and the pipeline when the user takes water next time because the system cannot detect whether the water replenishing is finished. The control method of the water storage device provided by the embodiment of the invention mainly solves the problem that the water storage device is continuously supplied with water after the system is powered on, if no probe signal exists, normal water supply is carried out, and if the probe signal exists, a water replenishing stage is carried out.

The controller is electrically connected with a judging module for judging whether the detected water level state value meets the water supplementing condition.
The controller is electrically connected with a counting module and used for recording the water level state value.
According to the control method of the water storage device, in the existing water storage scheme with the probe water tank 4, although a water replenishing solution is provided for the cavity problem, the system does not effectively detect the water replenishing process, so that when the power is off in the water replenishing process, the system cannot judge whether water replenishing is finished or not after being electrified again, and the cavity of the water tank 4 is caused. Therefore, the system is provided with a water tank 4 state value X to record the water replenishing condition, the value of X is read to determine whether the water replenishing operation is finished or not when the system is powered on, and if the water replenishing operation is not finished, the water replenishing time is determined according to the value of X.
