Detailed ways

The present invention first provides a control method of an air treatment device. FIG. 1 is a schematic structural diagram of an air treatment device according to an embodiment of the present invention, and FIG. 2 is a schematic cross-sectional view of an air treatment device according to an embodiment of the present invention.

Referring to FIGS. 1 and 2 , the air treatment apparatus 1 of the present invention includes a casing 10 . The housing 10 is provided with an air inlet and an air outlet 13 . The air outlet 13 is used to communicate with the room. In a specific embodiment, the number of air inlets may be one, and the air inlets may be communicated with indoors or outdoors. In another specific embodiment, the number of air inlets may also be two or more. For example, in the embodiment shown in FIG. 1 , the number of air inlets is two, which includes a The indoor air inlet 11 and the outdoor air inlet 12 for communicating with the outdoors to introduce fresh air. The indoor air inlet 11 and/or the outdoor air inlet 12 can be selectively opened or closed through the damper, so as to selectively allow indoor return air and/or outdoor fresh air to enter the air handling device 1 and be sent out after being processed by the air handling device 1 .

It should be noted that the indoor in the embodiment of the present invention refers to the indoor environment space where the air handling device 1 is located, and the outdoor in the embodiment of the present invention refers to the outdoor environment space.

An air duct connecting the air inlet and the air outlet 13 is formed in the housing 10, and the air duct is provided with a fan 21 for driving the air flow from the air inlet to the air outlet 13, a water storage tank 31 for accommodating water, and a rotatable fan 21. The drum 41 is arranged in the water storage tank 31 so as to use the rotation of the drum 41 to take out the water in the water storage tank 31 and use the carried water to wash and humidify the air flow when the air flow passes through the drum 41 . Specifically, when the drum 41 is rotated, the water in the water storage tank 31 can be brought into the air flow path. When the air flow is in contact with water, impurities such as impurities, fluff, and water-soluble harmful gases in the air flow can be dissolved in the water, thereby realizing the water cleaning of the air flow. At the same time, the airflow can also carry away part of the water vapor, thereby realizing the humidification of the airflow.

The applicant realizes that the degree of humidification of the airflow is closely related to the amount of water in contact with the airflow, and the amount of water in contact with the airflow depends on how fast the drum 41 rotates. For this reason, the present application devises a control method for the air treatment device 1 . FIG. 3 is a schematic flowchart of a control method of an air treatment device according to the first embodiment of the present invention. The control method may include:

Step S40, when the air treatment device 1 is in the water washing mode, obtain the indoor humidity of the indoor environment where the air treatment device 1 is located; in the water washing mode, the drum 41 is in a rotating state; and

In step S50, the rotational speed of the drum 41 is adjusted according to the indoor humidity, and the rotational speed of the drum 41 is inversely correlated with the indoor humidity.

That is to say, when the indoor humidity is low, the rotation speed of the drum 41 can be appropriately increased. The faster the drum 41 rotates, the more water it brings out in a unit time for contact with the airflow, and the higher the degree of humidification of the airflow. . When the indoor humidity is high, the rotation speed of the drum 41 can be appropriately reduced. The slower the drum 41 rotates, the less water it brings out in unit time for contact with the air flow, and the lower the degree of humidification of the air flow. Therefore, the control method of the present application can not only perform water cleaning on the airflow, but also effectively control the humidity of the airflow.

FIG. 4 is a schematic flow chart of adjusting the rotation speed of the drum according to the indoor humidity according to an embodiment of the present invention. In some embodiments, the step S50 of adjusting the rotational speed of the drum 41 according to the indoor humidity may specifically include:

Step S51, judging whether the indoor humidity is greater than or equal to the first preset humidity threshold; if the indoor humidity is greater than or equal to the first preset humidity threshold, go to step S52, and if the indoor humidity is less than the first preset humidity threshold, go to step S53;

Step S52, reducing the rotational speed of the drum 41 to reduce the amount of water used to contact the airflow, thereby reducing the humidity of the airflow;

Step S53, continue to judge whether the indoor humidity is less than or equal to the second preset humidity threshold; if yes, go to step S54, if not, go to step S55;

Step S54, increasing the rotational speed of the drum 41 to increase the amount of water used for contacting the airflow to increase the humidity of the airflow;

Step S55, keep the rotation speed of the drum 41 unchanged; wherein

The first preset humidity threshold is greater than the second preset humidity threshold.

FIG. 5 is a schematic flowchart of adjusting the rotational speed of the drum according to indoor humidity according to another embodiment of the present invention. In some embodiments, when the indoor humidity is greater than or equal to the first preset humidity threshold, the above step S52 may further include:

The rotation speed of the fan 21 is increased to increase the flow rate of the airflow and reduce the contact time between the airflow and the water, thereby reducing the humidity of the airflow.

In some embodiments, when the indoor humidity is less than or equal to the second preset humidity threshold, the above step S54 may further include:

The rotation speed of the fan 21 is reduced to reduce the flow rate of the airflow and increase the contact time between the airflow and the water, thereby increasing the humidity of the airflow.

Of course, when the indoor humidity is between the second preset humidity threshold and the first preset humidity threshold, the rotational speed of the fan 21 can be kept unchanged.

That is to say, the present application also adjusts the humidity of the air flow by controlling the rotational speed of the fan 21. The change of the rotational speed of the fan 21 can adjust the speed of the air flowing through the drum 41, that is, the time during which the air is in contact with the water. The shorter the contact time of the water on the 41, the lower the degree of humidification of the airflow, on the contrary, the smaller the rotational speed of the fan 21, the higher the degree of humidification of the airflow.

In some embodiments, the housing 10 is further provided with a return air port 14 for connecting the indoor environment and the air duct, and an electrically controlled air door 22 is arranged at the air return port 14; on the air flow path in the air duct, the air return port 14 is located in the water storage tank Downstream of 31. When the fan 21 is running, the indoor air and/or outdoor fresh air entering the housing 10 through the air inlet can be forced to flow to the air outlet 13 through the air duct. At the same time, when the air return port 14 is opened, part of the air in the room can enter the air duct through the air return port 14 under the action of the negative pressure generated by the air supply in the housing 10, so as to mix with the air flowing through the drum 41 and flow out from the air outlet. 13 sent. Since the indoor air entering the air duct through the air return port 14 is not humidified by the drum 41, the humidity is relatively low. Therefore, the humidity of the mixed airflow formed by mixing the indoor air entering the air duct through the air return port 14 and the airflow flowing through the drum 41 is lower than the humidity of the airflow after being humidified by the drum 41 .

To this end, FIG. 6 is a schematic flowchart of adjusting the rotational speed of the drum according to the indoor humidity according to another embodiment of the present invention. When the indoor humidity is greater than or equal to the first preset humidity threshold, the above step S52 may further include:

Control the electronically controlled damper 22 to open the air return port 14 or increase the opening of the air return port 14 to allow indoor air to enter the air duct through the air return port 14 and mix with the air flow processed by the drum 41 and then be sent out from the air outlet 13 or increase the air flow rate. The amount of indoor air entering into the air duct by the return air port 14 .

When the indoor humidity is less than or equal to the second preset humidity threshold, the above step S54 may further include:

The electronically controlled damper 22 is controlled to close the air return port 14 or reduce the opening of the air return port 14 to prevent or reduce indoor air from entering the air duct through the air return port 14 .

That is to say, the present application also adjusts the air humidity by adjusting the opening and closing or the opening degree of the air return port 14. The opening degree of the air return port 14 determines the amount of air flow without humidification entering the air duct through the air return port 14. The mixing of the air current and the air humidified by the drum 41 can adjust the overall humidity of the air flow sent from the air handling device 1 .

The present application comprehensively adjusts the humidity of the airflow by combining the rotational speed of the drum 41, the rotational speed of the fan 21, the opening and closing of the air return port 14, etc., to a large extent, to speed up the air humidity adjustment.

FIG. 7 is a schematic flowchart of a control method of an air treatment apparatus according to a second embodiment of the present invention. In some embodiments, before acquiring the indoor humidity of the indoor environment where the air treatment device 1 is located, the control method of the present invention further includes:

Step S31, after the air treatment device 1 is turned on, obtain the height of the water in the water storage tank 31; and

Step S32, when the height of the water in the water storage tank 31 reaches a preset height, the drum 41 is started, so that the air treatment device 1 enters the water washing mode.

That is to say, the drum 41 is activated only when the water volume in the water storage tank 31 is sufficient, and the air treatment device 1 is urged to enter the water washing mode, so as to ensure better purification effect and humidification effect in the water washing mode. This is because the present application uses the rotation of the drum 41 to take out the water in the water storage tank 31 to perform water cleaning and humidification on the airflow. If the water in the water storage tank 31 is too small, the amount of water brought out by the drum 41 is small, and even cannot bring out the water, which will seriously affect the purification effect and humidification effect of the airflow.

Further, when the height of the water in the water storage tank 31 is lower than the preset height, a prompt signal for prompting adding water into the water storage tank 31 may be issued.

FIG. 8 is a schematic flowchart of a control method of an air treatment apparatus according to a third embodiment of the present invention. In some embodiments, the air inlet includes an outdoor air inlet 12 for communication with the outdoors. In these embodiments, before acquiring the height of the water in the water storage tank 31, the control method of the present invention further includes:

Step S21, judging whether the preset fresh air opening condition is met; if yes, go to step S22;

In step S22, the air handling device 1 is started, so that the air inlet and the air outlet are opened, and the fan 21 is started to operate.

That is to say, when the outdoor fresh air is introduced into the room through the outdoor air inlet 12, the types and amounts of impurities and harmful gases in the outdoor fresh air are relatively large. Therefore, the air treatment device 1 of the present application is used for water washing and purification of the outdoor fresh air. Humidification and then input into the room can effectively improve the quality of indoor air.

Further, the above-mentioned fresh air opening condition may include receiving an indication signal for instructing the introduction of fresh air into the room and/or detecting that the indoor air quality index exceeds a preset index. That is to say, the air treatment device 1 can be activated when receiving the fresh air introduction instruction signal sent by the user, or can be automatically activated when the indoor air quality index exceeds the standard and outdoor fresh air needs to be introduced.

Specifically, the indoor air quality index may include the concentrations or contents of various gases, such as the concentrations or contents of carbon dioxide, formaldehyde, and benzene.

Applicants have recognized that there is a problem with the water scrubbing of the airflow with the drum 41 . When used for a long time, certain pollutants may accumulate on the drum 41. If it is not cleaned in time, the dirt on the drum 41 may accumulate and thicken, which will affect the life and function of the drum 41, thereby affecting the air purification effect.

To this end, FIG. 9 is a schematic flowchart of a control method of an air treatment apparatus according to a fourth embodiment of the present invention. In some embodiments, the control method of the present invention further includes:

Step S11, obtaining the cleanliness of the drum 41; and

Step S12 , when the cleanliness of the drum 41 is less than the preset minimum cleanliness, the drum cleaning mode for cleaning the drum 41 is entered.

In this way, the self-cleaning of the drum 41 is realized, the service life thereof is prolonged, and the good water washing ability is ensured for a long time.

Specifically, the above steps S11 and S12 may be performed before step S21 , or may be performed after the air treatment device 1 enters the water washing mode, or may be performed cyclically according to a preset time period. That is to say, the above steps S11 and S12 and other steps are not limited in order.

Further, in the drum cleaning mode, the drum 41 is in a rotating state, and the fan 21 is in a stopped state. That is to say, when the drum 41 is cleaned, the drum 41 continues to rotate, which can improve the uniformity and thoroughness of the cleaning of the drum 41 . In addition, when the drum 41 is cleaned, the fan 21 is stopped, that is, the air handling device 1 does not introduce or send out air flow, thereby preventing the dirt cleaned on the drum 41 from entering the room with the air flow and causing secondary pollution.

The present invention also provides an air treatment device 1 , and the air treatment device 1 of the present invention includes a casing 10 . The housing 10 is provided with an air inlet and an air outlet 13 . An air duct connecting the air inlet and the air outlet 13 is formed in the housing 10, and the air duct is provided with a fan 21 for driving the air flow from the air inlet to the air outlet 13, a water storage tank 31 for accommodating water, and a rotatable fan 21. The drum 41 is arranged in the water storage tank 31 and allows the air flow in the air duct to flow through, so as to use the rotation of the drum 41 to bring out the water in the water storage tank 31 and use the water to carry out the air flow when the air flow passes through the drum 41. Water washes and humidifies.

FIG. 10 is a schematic structural block diagram of an air treatment apparatus according to an embodiment of the present invention. In particular, the air treatment device 1 further includes a humidity acquisition device 61 and a control device 62 . The humidity obtaining device 61 is used to obtain the indoor humidity of the indoor environment where the air handling device 1 is located. Specifically, the humidity acquisition device 61 may be a humidity sensor. The control device 62 may include a processor 621 and a memory 622. The memory 622 stores a machine executable program 623, and when the machine executable program 623 is executed by the processor 621, is used to implement the control method described in any of the above embodiments.

Further, the air treatment device 1 further includes a driving mechanism 42 for driving the drum 41 to rotate, and the rotational speed of the drum 41 can be adjusted by controlling the driving mechanism 42 . Specifically, the drive mechanism 42 may include a motor, a gear transmission assembly, and the like.

In some embodiments, the air flow in the air flow path flows through the drum 41 along the radial direction of the drum 41 , and the drum 41 may include a horizontally extending rotating shaft 411 and a plurality of rotating disks 412 pierced on the rotating shaft 411 and arranged at intervals , so that when the drum 41 rotates, the water in the water storage tank 31 is brought out through the rotating disk 412, so that when the air flows through the drum 41 through the gap between the two adjacent rotating disks 412, the water attached to the rotating disk 412 passes through the water. The air stream is washed with water.

That is to say, a gap is formed between every two adjacent rotating disks 412, and when the airflow flows to the drum 41 along the radial direction of the drum 41, it can flow through the gap between the two adjacent rotating disks 412, and the drum 41 is hardly It will produce any resistance to the airflow, so it will hardly affect the air outlet speed of the air outlet 13 . When the drum 41 rotates, part of the water in the water storage tank 31 may adhere to the rotating disk 412 and be taken out with the rotation of the rotating disk 412 . When the airflow passes through the drum 41 and contacts the water on the rotating disk 412, impurities, fluff, water-soluble harmful gases and other pollutants in the airflow can be dissolved in the water, thereby realizing the water cleaning of the airflow. The rotating disk 412 provides a reliable and large contact area for the airflow and the water, and the distribution of the water on the rotating disk 412 is relatively uniform, so it can ensure that the water and the airflow are fully and effectively contacted, and the purification effect and purification of the airflow are improved. efficiency.

It can be understood that the height of the drum 41 in the water storage tank 31 can be set such that when the water in the water storage tank 31 reaches the highest water level, at least part of the drum 41 is above the water surface of the water storage tank 31 so that at least part of the drum 41 is above the water surface. The segment is in the airflow flow path so that at least a portion of the drum 41 is submerged in water when the water in the water storage tank 31 reaches a minimum level so that the water can be brought out as the drum rotates.

The water level in the water storage tank 31 can be obtained by existing methods such as a liquid level sensor, a magnetic float, etc. When the liquid level in the water storage tank 31 is lower than the minimum water level, the user can be prompted to the water storage tank 31 through a display screen, a buzzer, etc. Add water inside.

In some embodiments, the water storage tank 31 is further provided with a liquid level detection device, and the liquid level detection device is used to detect the liquid level of the water contained in the water storage tank 31 .

In some embodiments, the air treatment device 1 further includes a prompting device for sending a prompting signal for prompting adding water into the water storage tank 31 when the height of the water in the water storage tank 31 is lower than a preset height.

In some embodiments, the air treatment device 1 further includes an air quality detection device for detecting the indoor air quality index.

In some embodiments, the air treatment device 1 further includes a cleanliness detection device and an automatic cleaning device. The cleanliness detection device is used to detect the cleanliness of the drum, so as to obtain the dirty condition of the drum in time. The automatic cleaning device is used to clean the drum in a controlled manner, thereby realizing the self-cleaning of the drum and restoring the water washing and humidifying ability of the drum.

Specifically, the cleanliness detection device may include a light transmitter for emitting light and a light receiver for receiving light, so as to judge the light transmittance of the drum according to the light received by the light receiver, so as to transmit light according to the light transmittance Rate to judge the cleanliness of the drum.

Specifically, the automatic cleaning device can be any one of a brush, a nozzle and an ultrasonic cleaning device.

The applicant has recognized that when the air temperature is low, especially when fresh air with an outdoor temperature below zero is introduced into the room, it is easy to cause freezing in the water storage tank 31 when the air contacts with water. To this end, in some embodiments, the water storage tank 31 is provided with a water tank heating device 33 for heating the water in the water storage tank 31, so as to use the heated water to perform water washing on the airflow passing through the water washing device. When the heated water comes into contact with the airflow, it transfers heat to the airflow, thereby increasing the temperature of the airflow.
