The detection unit also comprises an infrared thermopile sensor for distinguishing whether the surrounding obstacles are people or objects; and when the judgment result is that the person is a person and the distance between the dehumidifier and the human body is judged to be greater than the first set threshold value, the air outlet direction of the dehumidifier is controlled according to the position of the person so that the dehumidifier does not directly blow to the human body.

The dehumidification execution unit comprises an air supply fan, an air outlet grid and a motor for driving the dehumidifier to move.

As shown in fig. 2, the method for controlling a dehumidifier according to an embodiment of the present invention includes the following steps:
a control method of a dehumidifier comprises the following steps:
s01: starting/waking up the dehumidifier;
s02: detecting and acquiring the distance between the dehumidifier and surrounding objects;
s03: judging whether the distance between the dehumidifier and the surrounding objects is smaller than a first set threshold value:
if so, adjusting the position of the dehumidifier to enable the distance between the dehumidifier and the surrounding objects to be larger than or equal to a first set threshold; if not, executing the next step;
s04: a dehumidification mode is performed.
Step S04 further includes: and detecting whether a person exists in a preset range around the dehumidifier in real time, and controlling the air outlet direction and/or the air speed of the dehumidifier according to the position of the person when the judgment result shows that the person exists. Preferably, the step S04 of "controlling the wind direction and/or the wind speed of the dehumidifier" includes: the air outlet direction of the dehumidifier is controlled to prevent the dehumidifier from blowing towards people directly.
Alternatively, the step S02 of "detecting and acquiring the distance between the dehumidifier and the surrounding object" includes: detecting the distance between the dehumidifier and surrounding obstacles, distinguishing whether the obstacles are people or objects, and extracting the distance between the dehumidifier and the surrounding objects.
Alternatively, the step S02 of "detecting and acquiring the distance between the dehumidifier and the surrounding object" includes: and detecting the distance between the dehumidifier and surrounding obstacles, and taking the distance between the dehumidifier and the surrounding obstacles as the distance between the dehumidifier and the surrounding objects. The setting mode saves cost, and only the distance sensor is adopted to measure the distance between the dehumidifier and the barrier.
Optionally, the matrix infrared thermopile sensor is turned on to detect whether a person is present in the room, and at the same time, to distinguish between a person and an object in the room. Since the person is active, by distinguishing between the person and the object, only the distance between the dehumidifier and the object is calculated, not the distance between the dehumidifier and the person. The direction movement of the dehumidifier is more accurate. Other modes can be adopted to distinguish people and objects, such as an infrared binocular camera, people and objects can be directly distinguished, and the distance can be calculated.
The distance sensor may be activated to detect the distance of objects around the dehumidifier as shown in fig. 1, which illustrates a schematic diagram of the dehumidifier detecting the distance of a person or object. The distance between an object such as a wall and the dehumidifier can be RW1, and then the distance is compared with a first set threshold RS1, if RW1-RS1 are less than 0, the motor is started, the bottom roller of the dehumidifier is driven to rotate, and the working direction of the dehumidifier is adjusted. And executing the next dehumidification operation until the adjusted distance measurement value meets RW1-RS1 more than or equal to 0.
The distance sensor can also detect that the actual distance between the humidifier and the person can be calculated as RW2, and compared with the set second set threshold RS2, the dehumidifier and the person can be kept at a proper distance.
The manner of adjusting the position of the dehumidifier in step S03 is: and starting a motor for driving the dehumidifier, wherein the motor drives wheels at the bottom of the dehumidifier to move the dehumidifier.
Step S04 is followed by: s05: after the dehumidification is finished, the dehumidifier is in a standby state;
s06: and (3) comparing the detected actual humidity RH1 with the set humidity RH0 of the dehumidifier: when the difference RH1-RH0 is larger than or equal to the preset difference RHS, returning to the step S01; otherwise, return to the initial step of S06.
Optionally, the preset difference value RHS may be 5%, that is, it is determined whether the difference between the actual value of the relative humidity in the room and the set value is greater than or equal to 5%, that is: RH1-RH0 is more than or equal to 5 percent. If the difference is larger than or equal to 5%, waking up the dehumidifier, and repeating the steps S01 to S07; if the humidity value is less than 5%, the dehumidification function of the dehumidifier is closed, the humidity value is continuously detected, and the humidity of the room is ensured to be in a dynamic balance state under the action of the dehumidifier.
Has the advantages that:
according to the dehumidifier and the control method thereof, when the dehumidifier is started, the distance between the dehumidifier and the surrounding objects is detected, and the dehumidifier and the objects are kept at a reasonable distance by controlling the movement of the dehumidifier. Through the arrangement, the invention can avoid the influence on dehumidification effect caused by that moisture can not enter and dry air can not exit when the dehumidifier runs too close to an object, such as wall-mounted running. The invention can leave enough space around the dehumidifier when the dehumidifier runs, and the air can be smoothly fed and discharged, thereby improving the dehumidification efficiency. The invention can control the air inlet and outlet of the dehumidifier, and avoid discomfort to human body.
Exemplary embodiments of the present disclosure are specifically illustrated and described above. It is to be understood that the present disclosure is not limited to the precise arrangements, instrumentalities, or instrumentalities described herein; on the contrary, the disclosure is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
