S01, when the dehumidifier is performing dehumidification, the control device detects the presence of the water tank.

S02, when the water tank is removed from the dehumidifier, the control device activates the heating device to heat the hygroscopic material.

Using the method for controlling a dehumidifier provided by an embodiment of the present disclosure, a hygroscopic material is placed under the water tank of the dehumidifier. When the dehumidifier is dehumidified, if the water tank is removed, subsequent condensed water can drip onto the hygroscopic material The dehumidifier is also equipped with a heating device that can heat the hygroscopic material. When it is detected that the water tank is removed from the dehumidifier, the condensed water absorbed by the hygroscopic material can be evaporated by starting the heating device to heat the hygroscopic material. Timely treatment of condensed water. In this way, when the dehumidifier performs dehumidification and the water tank is removed, the condensed water can be prevented from dripping onto the floor of the dehumidifier or the floor of the room, thereby avoiding generation of peculiar smell and improving user experience.

The dehumidifier continuously produces condensed water during the dehumidification process. If the water tank is removed, the condensed water will drip down and be absorbed by the hygroscopic material. The presence of the water tank is detected by the control device, and when the water tank is removed from the dehumidifier, The heating device is controlled and started to heat the hygroscopic material, so that the inhaled condensed water can be treated in time.

Here, the existence state of the water tank may be acquired by the control device through its own infrared sensor. The acquisition of the existence status of the water tank can be obtained continuously, so that the dehumidifier can respond in time according to the changes of the above parameters; it can also be obtained periodically, for example, the existence status of the water tank is obtained every 1 minute, so as to maintain dynamic control while reducing the amount of data processing.

The speed evaporates the moisture in the hygroscopic material.

Optionally, the first power is 4W˜6W. The first power can be selected within this range, for example, 5W. With the heating power within this range, the moisture in the hygroscopic material can be evaporated at a suitable evaporation rate when the water tank is removed from the dehumidifier.

Here, the heating power of the heating device is adjustable, and those skilled in the art can adjust the heating power to the first power.

As shown in FIG. 4 , an embodiment of the present disclosure also provides another method for controlling a dehumidifier, including:

S03, the control device acquires the duration of the water tank being removed from the dehumidifier.

S04, the control device controls the heating device to continue heating or to turn off according to the comparison result of the duration and the preset time.

Optionally, the sum of the heating duration for continuing heating and the duration of the water tank being removed from the dehumidifier is equal to the preset duration. In this way, if the heating device needs to continue heating, the subsequent heating time plus the previous heating time should be equal to the preset time, so that the condensed water in the hygroscopic material can be evaporated in time.

The preset duration can be measured according to the test. For example, a humidity sensor is installed in the hygroscopic material to detect the humidity in the hygroscopic material. When the time is started, the heating device is controlled to heat with the first power. When the humidity in the hygroscopic material is less than the preset value, the timing ends, and the recorded duration is used as the preset duration. The preset value can be 10%, 15% or 20%, etc.

The heating device may not completely evaporate the water in the hygroscopic material, and may stop heating when a small amount of water remains, and use residual heat to evaporate the remaining water.

With reference to FIG. 5 , an embodiment of the present disclosure also provides another method for controlling a dehumidifier, including:

S05, the control device judges whether the duration is greater than a preset duration. If yes, execute step S051, otherwise execute step S052.

S051, the control device turns off the heating device.

S052, the control device controls the heating device to continue heating the hygroscopic material.

The preset time can reflect the evaporation of moisture in the hygroscopic material. When the heating reaches the preset time, it indicates that the moisture in the hygroscopic material evaporates relatively completely. When the heating does not reach the preset time, it indicates that the moisture in the hygroscopic material evaporates incompletely. , need to continue heating.

In actual operation, for example, the preset duration is 5 minutes, and the control device detects that the duration of the water tank being removed from the dehumidifier has reached 5 minutes, then after 5 minutes, the control device turns off the heating device. For another example, if the preset duration is 5 minutes, the control device detects that the water tank has been removed from the dehumidifier for 3 minutes, and then the water tank is put back into the dehumidifier, then the control device controls the heating device to continue heating the hygroscopic material for 2 minutes and then stop heating.

S053. After detecting that the water tank is put back into the dehumidifier, the control device determines whether the dehumidifier is in a dehumidification state. If yes, execute step S0531, otherwise execute step S0532.

S0531. The control device controls the heating device to continue heating with the first power.

S0532. The control device controls the heating device to continue heating with the second power or the third power. The first power is less than the second power, and the second power is less than the third power.

By adopting the method for controlling the dehumidifier provided by the embodiments of the present disclosure, when the water tank is put back into the dehumidifier, the heating power of the heating device can be further controlled according to the current operating state of the dehumidifier, so as to more accurately control the moisture in the moisture-absorbing material. Moisture evaporates. If the dehumidifier is still in the dehumidification state when the water tank is put back into the dehumidifier, then the heating device is controlled to heat with a small first power. If the temperature is too high, the heat will be transferred to the water tank, thereby avoiding the evaporation of the larger condensed water collected in the water tank due to the increase in temperature, thereby preventing the indoor air humidity from rising again.

If the dehumidifier is not in the dehumidification state when the water tank is put back into the dehumidifier, then the heating device is controlled to continue heating with a higher second power or third power, so that the moisture in the hygroscopic material evaporates as soon as possible. When the water tank is put back, the space between the water tank and the hygroscopic material becomes smaller, the air circulation is not smooth, and the evaporation effect of the moisture in the hygroscopic material is weakened, which in turn leads to the retention of moisture between the hygroscopic material and the water tank, and the breeding of bacteria.

Optionally, the first power is 4W-6W, the second power is 8W-12W, and the third power is 13W-17W. The first power, the second power and the third power can be selected within corresponding value ranges, for example, the first power is 5W, the second power is 10W, and the third power is 15W.

In the embodiment of the present disclosure, the heating power of the heating device can be adjusted, and those skilled in the art can adjust the heating power to the first power, the second power or the third power according to actual needs.

As shown in FIG. 7 , an embodiment of the present disclosure also provides another method for controlling a dehumidifier, including:

S051, the control device turns off the heating device.

S053. After detecting that the water tank is put back into the dehumidifier, the control device determines whether the dehumidifier is in a dehumidification state. If yes, execute step S0531, otherwise execute step S0533.

S0533, the control device judges whether the dehumidifier enters the dehumidification state within the set duration, and the set duration is less than the absolute value of the difference between the preset duration and the duration of the water tank being removed from the dehumidifier. If yes, execute step S0533a, otherwise execute step S0533b.

S0533a. The control device controls the heating device to continue heating with the third power.

S0533b. The control device controls the heating device to continue heating with the second power. The first power is less than the second power, and the second power is less than the third power.

Using the method for controlling the dehumidifier provided by the embodiment of the present disclosure, when the water tank is put back into the dehumidifier, if the dehumidifier is not in the dehumidification state, the heating device is controlled to heat with the second higher power or the third power ; If it is further detected that the dehumidifier has entered the dehumidification state within the set time, it will use the third highest power to continue heating at this time, so as to make the remaining moisture in the hygroscopic material quickly before more condensed water collects in the water tank. Evaporation, try to reduce the impact on the temperature of the condensed water in the water tank; if it is further detected that the dehumidifier has not entered the dehumidification state within the set time, it can still be carried out with the second power between the first power and the third power. heating.

Here, the set duration is less than the absolute value of the difference between the preset duration and the duration of the water tank being removed from the dehumidifier. For example, if the preset duration is 5 minutes, and the duration for the water tank to be removed from the dehumidifier is 3 minutes, then the preset duration can be 1 minute, 1.5 minutes, etc.

The dehumidifier enters the dehumidification state within the set time, indicating that there is a dehumidification demand in the current indoor environment. Therefore, controlling the heating device in combination with the operating status of the dehumidifier can take into account the functional requirements of various aspects and make the moisture-absorbing material more effective in the treatment of condensed water. Accurate and reasonable.

As an example, after the control device continues heating with the second power or the third power, it further includes:

The control device secondarily adjusts the heating power of the heating device and continues to heat the hygroscopic material according to the dripping rate of the condensed water within the duration.

The greater the dripping rate of condensed water, the more moisture absorbed by the hygroscopic material, and vice versa. According to the dripping rate of condensed water, the heating power is adjusted twice, and the moisture inside the hygroscopic material can be made timely with more accurate heating power. evaporation, and minimize the energy consumption of the heating device.

Optionally, the control device secondarily adjusts the heating power of the heating device according to the dripping rate of the condensed water within the duration, including:

When the dripping rate of the condensed water is greater than a preset rate, the control device increases the heating power of the heating device;

When the dripping rate of condensed water is less than a preset rate, the control device reduces the heating power of the heating device, and adds the heating device to intermittently heat at a preset interval.

If the dripping rate is greater than the preset rate, it indicates that the condensed water drips faster and the moisture in the hygroscopic material is too much, so increase the heating power to evaporate the water as soon as possible; if the dripping rate is lower than the preset rate, it indicates that the condensed water drips slowly and absorbs moisture There is less moisture in the material, so the heating power can be reduced to reduce energy consumption. The preset rate is eg 1 drop/second. Adjust the range of the heating power, for example, 5%. Increasing the heating power can increase 5% of the original heating power. The same is true for reducing the heating power.

Optionally, the control device includes a pressure sensor, the pressure sensor is arranged on a partial area of the surface of the hygroscopic material, and the dripping rate of the condensed water is detected by the pressure sensor. The pressure sensor can sense the dripping of water droplets, and combined with the time interval of the dripping of water droplets, the dripping rate can be measured.
