The water storage equipment is arranged in electronic equipment, the electronic equipment can be a dehumidifier or a water purifier and the like, the electronic equipment needing the water storage equipment is used, and the running time of the electronic equipment can be measured by a timer arranged in the electronic equipment. The electronic equipment starts to operate according to the control of a user or when set time or other conditions are reached, and after the electronic equipment starts to operate, the weight m of water in the water storage equipment or the water storage equipment and the operation time of the electronic equipment are collected in the mode. The collected running time of the electronic equipment is continuous running time, and the water storage device needs to be timed again when the water storage device drains water in the middle.
Step S20, when the collected weight m is larger than or equal to a preset weight threshold value and the running time is larger than or equal to a preset time, judging that the water storage equipment is full of water;
and step S30, when the collected weight m is smaller than a preset weight threshold value or the running time is smaller than preset time, judging that the water storage equipment is not full of water.
The method comprises the steps that a weight threshold value and preset time are set in advance, the weight threshold value can be 80% or 85% of the water fullness of the water storage equipment, the weight threshold value is set according to actual requirements, the preset time is 80% or 85% of the running time of the electronic equipment when the water storage equipment is full, and the preset time is set according to the actual requirements.

When the water level switch is judged to be full through the weight m and the running time and the water level switch gives an alarm, the water level switch is judged to be normal; and when the water level switch is not alarmed and the water level switch is not full, the water level switch is normal. Or when the water level switch is judged to be not full through the weight m and the running time and the water level switch is not alarmed, the water level switch is judged to be full through the weight m and the running time, and the water level switch is normal when the water level switch alarms; when the water level switch is judged to be full through the weight m and the running time, but the water level switch is not alarmed, the water level switch is judged to be not full through the weight m and the running time, and when the water level switch is not alarmed, the water level switch is not normally switched.
To better describe the embodiment of the present invention, referring to fig. 4, taking a dehumidifier as an example, the water storage device is a water tank in the dehumidifier, and the process is as follows:
step S101, collecting the weight m of a dehumidifier water tank and the continuous operation time t of a dehumidifier; step S102, determine that m > m1 and t > t 1? If yes, executing step S103, otherwise, executing step S104; in step S103, is the water level switch float activated?

If yes, executing step S107, otherwise, executing step S108; step S107, water is not full; in step S108, the water is not full and the water level switch is in failure. The pressure sensor is positioned at the bottom of the water tank, and the weight m of the water tank is obtained through conversion by measuring the pressure of the water tank; m1 is related to the weight M of the water full of the corresponding dehumidifier water tank, and M1 is 80% M; the continuous operation time of the dehumidifier is the time that the dehumidifier continuously operates from the starting up, and water is not poured in the midway; t1 is related to the total time T required by the corresponding dehumidifier to continuously run full of water, and T1 is 80% T; the action of the floater of the dehumidifier means that the water level switch of the dehumidifier is driven by the buoyancy of water after the dehumidifier is full of water. When m is more than m1, t is more than t1 and the water level switch is actuated, the water level is full P2; when m is larger than m1, t is larger than t1 and the water level switch does not act, the water is full and the water level switch breaks down; when m is less than m1, t is less than t1 and the water level switch acts, the water is not full and the water level switch breaks down; when m is less than m1, t is less than t1 and the water level switch is not actuated, the water is not full. According to the method, the weight m of the water tank of the dehumidifier and the continuous operation time t of the dehumidifier are collected, compared with the preset weight threshold m1 and the preset time threshold t1, and combined with a float water level switch judgment method in the traditional scheme, the electric leakage risk of full and overflowing water blocked by a float and the possibility of shutdown caused by alarm of insufficient water due to insufficient water during insufficient assembly can be effectively avoided through the three judgments, and the safety and the use efficiency of the dehumidifier are improved.
