At present, many clothes dryers are equipped with a water storage mechanism for storing condensed water, as shown in fig. 1, the water storage mechanism generally comprises a water storage tank 1 at the bottom of the clothes dryer and a water storage box 2 arranged above the water storage tank 1, wherein a water level switch 5 is arranged in the water storage tank 1, whether the water storage tank 1 reaches a drainage water level is judged through the water level switch 5, when the drainage water level is reached, the condensed water in the water storage tank 1 is drained to the water storage box 2 through a drain pipe 3 by a drain pump 6, when the water storage box 2 is full of water, redundant condensed water can overflow to the water storage tank 1 through an overflow pipe 4, when the water storage box 2 and the water storage tank 1 are full of water, an alarm can be sent out, so that a user can pour the water in the water storage box 2 in time, otherwise, the condensed water can overflow can be caused, the condensed.
Conventionally, a method of determining whether or not the water storage tank 2 and the water storage tank 1 are full by detecting the number of times the water level switch 5 is operated within a predetermined time is generally used. The defect of the judging method is that the water quantity of different loads condensed in the set time is different, so that the action times of the water level switch 5 are different; secondly, the liquid level of the condensed water in the running of the machine swings up and down along with the vibration of the machine, so that the water level switch 5 malfunctions. Therefore, the situation that whether the water storage box 2 and the water storage tank 1 are full or not is judged according to the action times of the water level switch 5, so that the judgment error exists, and corresponding treatment cannot be timely carried out.
Therefore, a method for determining water fullness in a water storage mechanism and a clothes dryer are needed to solve the above technical problems.

Detailed Description
The technical scheme of the invention is further explained by combining the attached drawings and the embodiment. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the elements associated with the present invention are shown in the drawings.
The invention provides a method for judging water fullness of a water storage mechanism, which comprises the steps of starting a drainage pump 6 to drain water to a water storage box 2 for a period of time after detecting the action of a water level switch 5 in a water storage tank 1, then detecting the state of the water level switch 5 again, and judging that the water storage box 2 and the water storage tank 1 are full if the action is still continuous.
Specifically, as shown in fig. 2, the determining method specifically includes the following steps:
s10, operating a clothes drying program;
s20, detecting whether the water level switch 5 in the water storage tank 1 is operated, if yes, executing step S30; if not, go to step S10;
s30, starting the drainage pump 6 to drain water for a period of time;
s40, detecting whether the water level switch 5 in the water storage tank 1 is still in the action state again, if so, judging that the water storage box 2 and the water storage tank 1 are full of water, and executing the step S50; if not. Step S10 is executed;
and S50, giving an alarm.
According to the method for judging the water fullness of the water storage mechanism, the state of the water level switch 5 is detected again after the drainage of the drainage pump 6, whether the water storage box 2 and the water storage tank 1 are full of water or not can be judged accurately, if the water level switch 5 is still in an action state, the water level in the water storage tank 1 is not reduced, namely the water storage box 2 cannot contain the condensed water drained from the water storage tank 1, at the moment, the water storage box 2 and the water storage tank 1 are both in the full state, the detection result is accurate and reliable, the influence of the load amount and the misoperation of the water level switch 5 is avoided, the alarm is timely, and the overflow of the condensed water is prevented.
Further, as shown in fig. 3, in steps S20 and S30, the drain pump 6 is started to drain water when the operation of the water level switch 5 is detected and the operation is continued for a set time T1, so that the water level switch 5 is not touched by the swing of the condensed water in the water storage tank 1 due to the vibration of the machine, and the malfunction of the water level switch 5 due to the vibration of the machine is avoided.
Further, as shown in fig. 3, in step S30, the drain time of the drain pump 6 may be set to T2, and the drain may be stopped when the drain of the drain pump 6 reaches the set time T2. Alternatively, the lowest water level of the drain pump 6 may be set, and the drain may be stopped when the drain pump 6 drains the water to a level at which the liquid level in the water storage tank 1 reaches the preset lowest water level.
Still further, as shown in fig. 3, a step S31 is further included between steps S30 and S40, that is, after the operation of the drain pump 6 is finished, the set time T3 is delayed, and the state of the water level switch 5 is detected again, so that the excessive condensed water in the water storage box 2 can be ensured to overflow back to the water storage tank 1, the liquid levels in the water storage box 2 and the water storage tank 1 are detected after reaching the stable state, the real water level in the water storage tank 1 is ensured to be detected by the water level switch 5, and the detection accuracy is further improved.
The invention also provides a clothes dryer, which adopts the method for judging the water fullness of the water storage mechanism. Specifically, referring to fig. 1, the clothes dryer includes a water storage mechanism including a water storage tank 1 and a water storage box 2, a drain pipe 3 and an overflow pipe 4 are connected between the water storage tank 1 and the water storage box 2, and a water level switch 5 and a drain pump 6 connected to the drain pipe 3 are provided in the water storage tank 1.
