For another example, the controller 113 obtains the water level of the condensed water in the water receiving tray 107 by a water level sensor, and further determines the amount of the condensed water to be precipitated.
In some embodiments, a water valve 109 is disposed below the drip tray 107 for controlling the outflow of condensed water from the drip tray 107.
In some embodiments, the motor 110 is used to provide driving power to the dryer 10. As shown in fig. 1, when the dryer 10 dries laundry, the motor 110 may drive the blower 106 to rotate through the motor shaft 111.

In some embodiments, temperature sensor 115 refers to a sensor that is capable of detecting temperature and converting the detected temperature value into a usable output signal. For example, the temperature sensor 115 may be configured to detect the temperature of the air in the laundry dryer 103, and send the detected temperature value to the controller 113, so that the controller 113 controls each electrical component to perform a corresponding operation according to the drying temperature detected by the temperature sensor 115.

The following detailed description of specific embodiments of the present application refers to the accompanying drawings.
The embodiment of the application provides a control method of a water heater, as shown in fig. 6, the method comprises the following steps:
s101, in the process of running a clothes drying program, the controller acquires the change condition of the clothes drying influence parameters and the change condition of the condensate water precipitation quantity of at least two latest continuous clothes drying stages.
Wherein, the clothes drying influence parameter at least comprises the fan rotating speed of the fan.
In some embodiments, the controller obtains the condensate water precipitation amount of the i-1 th drying stage and the condensate water precipitation amount of the i-1 th drying stage through the water amount detector at the end time of the i-1 th drying stage and the i-th drying stage respectively, and further determines the change condition of the condensate water precipitation amount according to the condensate water precipitation amount of the i-1 th drying stage and the condensate water precipitation amount of the i-th drying stage.
For example, the water quantity detector is a water level sensor, and the controller can obtain the water level of the condensed water in the water receiving disc through the water level sensor, so as to determine the condensate water precipitation corresponding to the water level of the condensed water according to the corresponding relation between the pre-stored water level and the condensate water precipitation. It is assumed that the controller determines the condensate water deposition amount to be X1 at the end time of the i-1 th laundry drying stage, and the controller determines the condensate water deposition amount to be X2 at the end time of the i-1 th laundry drying stage. If X2 > X1, this means that the condensate water deposition amount gradually increases, if X2 < X1, this means that the condensate water deposition amount gradually decreases, and if x2=x1, this means that the condensate water deposition amounts in the two laundry drying stages are the same.
Alternatively, each drying stage may be divided according to a time length, or may be divided according to a degree of drying the laundry. The drying stages may be preset by a manufacturer of the clothes dryer, or may be set by a user during the use of the clothes dryer, which is not limited in the embodiment of the present application.
S102, the controller is used for controlling the clothes drying influence parameters in the next clothes drying stage according to the change condition of the clothes drying influence parameters and the change condition of the condensate water precipitation quantity.
The realization of clothes drying function of the clothes dryer depends on evaporation of water in clothes in a clothes drying cylinder and precipitation of condensed water at an evaporator, when the rotation speed of a fan of the clothes dryer is increased, the air circulation speed in the clothes drying cylinder is increased, the heat radiating speed of circulating gas to the outside is increased, the temperature of the circulating gas is reduced, namely, the relation between the temperature of the circulating gas and the rotation speed of the fan is a monotonically decreasing function relation, the relation between the evaporation efficiency of water in the clothes and the rotation speed of the fan is not clear, and the relation between the precipitation efficiency of condensed water at the evaporator and the rotation speed of the fan is also not clear, namely, the relation between the drying efficiency of the clothes dryer and the rotation speed of the fan is not clear. However, when the clothes dryer dries clothes, the more the condensate water is precipitated within the same time period, the higher the precipitation speed of the water on the clothes at the evaporator is, the faster the water on the clothes is reduced, namely the higher the drying efficiency of the clothes dryer is. The controller can determine the influence of the change of the fan rotation speed on the condensate water precipitation according to the change of the fan rotation speed and the change of the condensate water precipitation in the clothes drying process, so that the fan rotation speed can be conveniently adjusted in the subsequent process.
For example, the fan speed in the clothes drying stage is greater than the fan speed in the previous clothes drying stage, if the condensate water precipitation amount in the clothes drying stage is greater than the condensate water precipitation amount in each previous clothes drying stage, the condensate water precipitation amount is increased along with the increase of the fan speed, that is, the clothes drying efficiency is increased, and then the fan speed should be continuously increased in the next clothes drying stage, so that the clothes drying efficiency is maintained at a higher level.
The technical solution shown in fig. 6 brings at least the following advantages: the change condition of the drying influence parameters and the change condition of the condensate water precipitation amount in two continuous drying stages are obtained, so that the change condition of the condensate water precipitation amount along with the drying influence parameters can be known, and the drying influence parameters in the next stage can be adjusted based on the change condition. Therefore, the drying efficiency of the clothes dryer can be kept at a higher level, the clothes drying time can be shortened, the time is saved for a user, and the use experience of the user is improved. In addition, when only the influence parameter of the drying is considered as the rotating speed of the fan, the drying temperature of the dryer is not required to be adjusted, so that the drying efficiency of the dryer can be improved under the condition that the power consumption of the dryer is not increased, and energy can be saved.
In some embodiments, based on fig. 6, as shown in fig. 7, the specific implementation of step S102 may include step S201 or step S202.
S201, if the fan rotating speed of the ith stage is greater than the fan rotating speed of the ith-1 stage, and the condensate water precipitation speed of the ith stage is greater than or equal to the condensate water precipitation speed of the ith-1 stage, the controller determines that the fan rotating speed of the (i+1) stage is the sum of the fan rotating speed of the ith stage and a first preset rotating speed.
Wherein, the condensate water precipitation speed of the ith stage is determined according to the condensate water precipitation amount of the ith stage and the time length of the ith stage, and the condensate water precipitation speed of the ith-1 stage is determined according to the condensate water precipitation amount of the ith-1 stage and the time length of the ith-1 stage. For example, when the length of the i-th drying stage is 3 minutes and the condensate water deposition amount of the i-th drying stage is 0.6L, the condensate water deposition rate of the i-th stage is 0.2L/min.
The first preset rotating speed is used for indicating the adjusting quantity of the controller to the rotating speed of the fan. For example, the first preset rotational speed is 100r/min, the fan rotational speed of the ith stage is 1500r/min, and if the controller determines that the fan rotational speed of the (i+1) th stage is the sum of the fan rotational speed of the ith stage and the first preset rotational speed, the fan rotational speed of the (i+1) th stage is 1600r/min.
It should be understood that when the fan speed of the i-th stage is greater than the fan speed of the i-1 th stage and the condensate water precipitation speed of the i-th stage is greater than or equal to the condensate water precipitation speed of the i-1 th stage, it means that the drying efficiency is also increased with the increase of the fan speed, and the fan speed is increased again in the next stage, so that the drying efficiency of the dryer can be maintained at a higher level.
S202, if the fan rotating speed of the ith stage is greater than the fan rotating speed of the ith stage and the condensate water precipitation speed of the ith stage is smaller than the condensate water precipitation speed of the ith stage, the controller determines that the fan rotating speed of the (i+1) th stage is the difference between the fan rotating speed of the (i-1) th stage and a second preset rotating speed.
It should be understood that when the fan speed of the i-th stage is greater than the fan speed of the i-1 th stage and the condensate water precipitation speed of the i-th stage is less than the condensate water precipitation speed of the i-1 th stage, it means that the drying efficiency is reduced with the increase of the fan speed, and the fan speed should be reduced in the next stage, so that the drying efficiency of the dryer can be maintained at a higher level.

S203, if the fan rotating speed of the ith stage is smaller than the fan rotating speed of the ith stage and the condensate water precipitation speed of the ith stage is larger than or equal to the condensate water precipitation speed of the ith stage, the controller determines that the fan rotating speed of the (i+1) th stage is the difference between the fan rotating speed of the ith stage and a third preset rotating speed.
It should be understood that when the rotational speed of the blower in the i-th stage is less than the rotational speed of the blower in the i-1 th stage and the condensate water precipitation speed in the i-th stage is greater than or equal to the condensate water precipitation speed in the i-1 th stage, it means that the drying efficiency is increasing as the rotational speed of the blower is decreasing, the rotational speed of the blower should be increased in the next stage so that the drying efficiency of the dryer can be maintained at a higher level.
S204, if the fan rotating speed of the ith stage is smaller than the fan rotating speed of the ith stage and the condensate water precipitation speed of the ith stage is smaller than the condensate water precipitation speed of the ith stage, the controller determines that the fan rotating speed of the (i+1) th stage is the sum of the fan rotating speed of the ith stage and a fourth preset rotating speed.
It should be understood that when the fan rotation speed in the i-th stage is smaller than the fan rotation speed in the i-1 th stage and the condensate water precipitation speed in the i-th stage is smaller than the condensate water precipitation speed in the i-1 th stage, it means that the drying efficiency is also reduced with the reduction of the fan rotation speed, and the fan rotation speed should be increased in the next stage so as to keep the drying efficiency of the dryer at a higher level.
The technical solution shown in fig. 8 brings at least the following advantages: if the fan rotating speed of the ith stage is smaller than that of the ith-1 stage, according to the change conditions of the condensate water precipitation speeds of the ith stage and the ith-1 stage, the influence condition of the smaller fan rotating speed on the condensate water precipitation speed can be known, and then the fan rotating speed of the next stage is changed, so that the condensate water precipitation speed is kept at a higher level as much as possible, and the drying efficiency is improved.
