Detailed ways

The present invention firstly provides a method for controlling an air conditioner indoor unit. FIG. 1 is a schematic structural diagram of an air conditioner indoor unit according to an embodiment of the present invention, and FIG. 2 is a schematic cross-sectional view of an air conditioner indoor unit according to an embodiment of the present invention. Referring to FIG. 1 and FIG. 2 , the air conditioner indoor unit 1 of the present invention includes a casing 10 , an air evening device 20 and a water washing device 30 .

The front part of the casing 10 is formed with an air supply port 11, and the middle part of the casing 10 is formed with a through passage 12 in the transverse direction. Two heat exchange air supply units 13 for delivering heat exchange airflow to the air supply port 11 are arranged inside the casing 10. , the two heat exchange and air supply units 13 are respectively located on lateral sides of the through channel 12 . It can be understood that the heat-exchanged airflow mentioned in the present invention refers to the airflow after heat exchange through the heat exchange device, and correspondingly, the unheated airflow refers to the airflow without heat exchange through any heat exchange device.

The air equalizer 20 is rotatably disposed in the passage 12 for blowing air toward the air outlet 11 . That is to say, the air uniformity device 20 is located between the two heat exchange and air supply units 13, so that the airflow sent by the air uniformity device 20 is located between the airflows sent by the two heat exchange and air supply units 13, which is convenient for the air uniformity device 20 to send out The airflow is mixed with the airflow sent by the two heat exchange air supply units 13.

The water washing device 30 is used for humidifying the air flow passing through it. The water washing device 30 communicates with the outside of the cabinet 10 and the air uniform device 20 to send the airflow outside the cabinet 10 to the wind uniform device 20 . That is to say, both the water washing device 30 and the air uniforming device 20 are independent of the two heat exchange and air supply units. The air evening device 20 indirectly communicates with the outside of the casing 10 through the water washing device 30 , and the air outside the casing 10 is humidified by the water washing device 30 and then directly flows to the air evening device 20 without any heat exchange process. The non-heat-exchanged airflow sent by the air-conditioning device 20 can be mixed with the heat-exchanged airflow sent by the two heat-exchanging air supply units 13, thereby relieving the air supply temperature of the indoor unit 1 of the air conditioner and preventing its outlet air temperature from being too high or If it is too low, the softness of the air supply of the indoor unit 1 of the air conditioner will be improved.

Fig. 3 is a schematic flowchart of a method for controlling an air conditioner indoor unit according to a first embodiment of the present invention. Referring to Fig. 3, the control method of the present invention comprises:

Step S20, in the water washing mode, receiving a control signal for controlling the rotation of the wind uniform device 20; and

Step S30, controlling the wind uniform device 20 to rotate in a corresponding direction according to the information contained in the control signal.

In the present invention, the wind uniform device 20 is set to be rotatable. In the water washing mode, the wind uniform device 20 can be controlled to rotate in the corresponding direction according to the received control signal, so that the high humidity and heat exchanged air sent by the wind uniform device 20 The airflow is sent to the corresponding area in a targeted manner, so that local environments with different humidity and temperature can be realized in the same indoor space, achieving the purpose of partitioned air supply and meeting the diverse needs of users.

The inventor realized that in the prior art, the start and stop of the air equalizer is realized by detecting the humidity of the indoor environment, which can only improve the indoor humidity environment from a macroscopic perspective, and cannot match the actual needs of users. This is because different human bodies have different degrees of sensitivity to humidity. Some people have drier skin, so they may prefer a humid environment with higher humidity; some people have moist skin, so they may prefer a drier environment.

For this reason, in some embodiments, the above control signal may be a humidity signal used to indicate the humidity of the human body in the indoor environment where the air conditioner indoor unit 1 is located. That is to say, this embodiment automatically adjusts the rotation direction of the air uniformity device 20 according to the humidity of the human body in the indoor environment, thereby adjusting the direction of the high-humidity airflow sent by the wind uniformity device 20 without heat exchange, intelligently matching different users The actual demand of the air conditioner does not require manual adjustment by the user, which improves the intelligence and comfort of the air conditioner indoor unit 1 .

Specifically, the humidity of the human body may be the humidity of the skin surface of the human body.

Fig. 4 is a schematic flowchart of a method for controlling an air conditioner indoor unit according to a second embodiment of the present invention. In some embodiments, the step S30 of controlling the wind uniform device 20 to rotate in a corresponding direction according to the information contained in the control signal may specifically include:

Step S32, judging whether the humidity of the human body included in the humidity signal exceeds the first preset humidity threshold; if yes, go to step S33; if not, go to step S34;

Step S33, controlling the wind uniform device 20 to rotate in a direction away from the human body;

Step S34, continue to judge whether the human body humidity contained in the humidity signal is lower than the second preset humidity threshold; if so, go to step S35;

Step S35, controlling the rotation of the air uniformity device 20 in a direction to align with the human body.

It can be understood that the second preset humidity threshold is smaller than the first preset humidity threshold.

That is to say, when the humidity of the human body is relatively high (such as exceeding the first preset humidity threshold), the air uniformity device 20 automatically turns to avoid the direction of the human body, so as to prevent the high-humidity airflow sent by the wind uniformity device 20 from directly blowing the human body, so that Most of the airflow felt by the human body is the heat exchange airflow sent from the heat exchange air supply unit 13, so as to prevent the user from feeling that the environment is too humid. When the humidity of the human body is low (for example, lower than the second preset humidity threshold), the air uniformity device 20 automatically turns to the direction of the human body, so that most of the high-humidity airflow sent by the wind uniformity device 20 is blown to the human body, so that The user is in a humid environment.

In some other embodiments, the magnitude relationship between the human body humidity and the second preset humidity threshold can also be judged first, and then the magnitude relationship between the human body humidity and the first preset humidity threshold can be judged, which will not be repeated here.

Fig. 5 is a schematic flowchart of a method for controlling an air conditioner indoor unit according to a third embodiment of the present invention. In some embodiments, the step S30 of controlling the wind uniform device 20 to rotate in a corresponding direction according to the information contained in the control signal further includes:

If the human body humidity contained in the humidity signal is between the second preset humidity threshold and the first preset humidity threshold, go to step S36;

Step S36, controlling the wind equalizer 20 to rotate reciprocally within a preset angle range.

That is to say, when the humidity of the human body is not too high or too low, neither the high-humidity airflow directly blows the human body nor the high-humidity airflow avoids the human body. At this time, the air equalizer 20 can be controlled to rotate reciprocally within a preset angle range, so as to improve the humidity uniformity of the entire indoor environment.

Specifically, the aforementioned preset angle range may be any angle range between 60° and 120° in front of the casing 10 .

In some other embodiments, the step S30 of controlling the wind uniform device 20 to rotate in a corresponding direction according to the information contained in the control signal further includes:

If the humidity of the human body contained in the humidity signal is between the second preset humidity threshold and the first preset humidity threshold, the air uniformity device 20 is controlled to rotate toward the front of the casing 10 and then stop rotating.

That is to say, when the humidity of the human body is not too high or too low, neither the high-humidity airflow directly blows the human body nor the high-humidity airflow avoids the human body. At this time, the air uniform device 20 can be controlled to rotate to the front of the casing 10, so as to better evenly mix with the two heat exchange airflows sent by the two heat exchange air supply units 13, and at the same time, it can also save Control the energy consumption required for the rotation of the wind uniform device 20 .

Fig. 6 is a schematic flowchart of a control method of an air conditioner indoor unit according to a fourth embodiment of the present invention. In some embodiments, before judging whether the humidity of the human body included in the humidity signal exceeds the first preset humidity threshold, the method further includes:

Step S31, acquiring the location information of the human body.

Thus, the rotation direction of the wind evening device 20 can be accurately adjusted according to the size relationship between the human body humidity and the first preset humidity threshold and the second preset humidity threshold.

Specifically, the position information of the human body can be obtained through any feasible means such as an infrared sensor, a radar sensor, and a radio frequency module.

When there are multiple human bodies in the indoor environment, the human body humidity of different human bodies may be different, and the requirements for the ambient humidity may also be different. For this reason, in some embodiments, the step S30 of controlling the wind uniform device 20 to rotate in a corresponding direction according to the information contained in the control signal may specifically include:

Comparing the humidity level of multiple human bodies; and

Control the wind uniform device 20 to rotate towards the direction of aiming at the human body with low humidity and avoiding the human body with high humidity.

That is to say, when the humidity of multiple human bodies is different, the wind evening device 20 can be rotated to the direction of facing the human body with lower humidity and avoiding the human body with higher humidity, so that the high-humidity airflow sent by it can be sent to more A human body with low humidity can not only meet the needs of a human body with low humidity for a humid environment, but also meet the needs of a human body with high humidity for a relatively dry environment.

In some embodiments, the control signal may be a humidity signal obtained directly through a human body humidity sensor disposed on the casing 10 . That is to say, the humidity of the human body can be obtained directly through the human body humidity sensor. Specifically, the human body humidity sensor can be arranged on the upper front side of the casing 10, so as to more comprehensively obtain the humidity of the human body at various positions in the indoor environment.

In some other embodiments, the control signal may be a humidity signal received from a wearable device connected to the air conditioner indoor unit 1 . That is to say, the humidity of the human body can be acquired through the wearable device worn by the user, and sent to the air conditioner indoor unit 1 . Specifically, the wearable device may be any device capable of obtaining the humidity of the user's body, such as a wristband, a helmet, and a backpack.

In some other embodiments, the control signal may also be a remote control signal received by a remote controller connected to the air conditioner indoor unit 1 . That is to say, the user can also manually adjust the rotation direction of the air equalizing device 20 through the remote control, thereby adjusting the air supply direction thereof, so as to meet the individual needs of the user.

In some embodiments, the water washing device 30 includes a water storage tank 31 for containing water and a drum 32 rotatably disposed in the water storage tank 31 . The water in the water storage tank 31 can be taken out when the drum 32 rotates. When the air flow passes through the drum 32 , it can contact the water brought out from the drum 32 , thereby washing the air flow with water. After the air flow passes through the drum 32 , the humidity increases, which can increase the humidity of the air flow sent to the air uniform device 20 . At the same time, substances such as impurities, lint, and water-soluble harmful gases in the airflow can also be dissolved in water, thereby achieving the purpose of purifying the airflow and enriching the functions of the air conditioner indoor unit 1 .

In these embodiments, refer to the schematic flowchart of the control method of the air conditioner indoor unit according to the fifth embodiment of the present invention shown in FIG. 7 . The control method of the present invention also includes:

Step S11, receiving a mode start signal for starting the water washing mode; and

Step S12 , driving the drum 32 to rotate, so as to take out the water in the water storage tank 31 through the drum 32 , so as to humidify and purify the air flow when the air flow passes through the drum 32 .

That is to say, in the water washing mode, the drum 32 is in a rotating state. When the air conditioner indoor unit 1 is not in the water washing mode, the drum 32 may be in a stopped state. At this time, the airflow outside the casing 10 only flows to the air uniforming device 20 through the water washing device 30 , and no humidification process is performed on the airflow. That is, at this time, the water washing device 30 is only equivalent to an air duct.

Certainly, in some alternative embodiments, the water washing device 30 may also be other devices capable of humidifying the airflow. For example, spray generators, water curtain forming devices, etc.

In some embodiments, the casing 10 is provided with a third air inlet 143 for communicating with the indoor environment and/or the outdoor environment to introduce airflow into the water washing device 30 , and the third air inlet 143 is provided with a damper. In these embodiments, the control method of the present invention also includes:

After receiving the mode start signal, control the damper to open the third air inlet 143;

After receiving the mode stop signal for stopping the water washing mode, the damper is controlled to close the third air inlet 143 .

That is to say, it is also possible to select whether to send a uniform air flow through the air uniform device 20 by setting the damper, which enriches the operation modes of the air conditioner indoor unit and satisfies the diverse needs of users.

The present invention also provides an air conditioner indoor unit 1 , and FIG. 8 is a schematic structural block diagram of the air conditioner indoor unit 1 according to an embodiment of the present invention. The air conditioner indoor unit 1 of the present invention includes a casing 10 , an air uniform device 20 , a water washing device 30 and a control device 40 .

The water washing device 30 is used for humidifying the air flow passing through it. The water washing device 30 communicates with the outside of the cabinet 10 and the air uniform device 20 to send the airflow outside the cabinet 10 to the wind uniform device 20 . That is to say, both the water washing device 30 and the air uniforming device 20 are independent from the two heat exchange and air supply units 13 . The air evening device 20 indirectly communicates with the outside of the casing 10 through the water washing device 30 , and the air outside the casing 10 is humidified by the water washing device 30 and then directly flows to the air evening device 20 without any heat exchange process. The non-heat-exchanged airflow sent by the air-conditioning device 20 can be mixed with the heat-exchanged airflow sent by the two heat-exchanging air supply units 13, thereby relieving the air supply temperature of the indoor unit 1 of the air conditioner and preventing its outlet air temperature from being too high or If it is too low, the softness of the air supply of the indoor unit 1 of the air conditioner will be improved.

The control device 40 includes a processor 41 and a memory 42, the memory 42 stores a machine executable program 43, and the machine executable program 43 is used to implement the control method described in any of the above embodiments when executed by the processor 41. Therefore, in the water washing mode, the control device 40 can control the wind uniform device 20 to rotate in the corresponding direction, so that the high-humidity and unheated airflow sent by the wind uniform device 20 can be sent to the corresponding area in a targeted manner, thereby Local environments with different humidity and different temperatures can be realized in the same indoor space, achieving the purpose of partitioned air supply and meeting the diverse needs of users.

Specifically, the processor 41 may be a central processing unit (central processing unit, CPU for short), or a digital processing unit or the like. The processor 41 sends and receives data through the communication interface. The memory 44 is used to store programs executed by the processor 41 . The memory 44 is any medium that can be used to carry or store desired program code in the form of instructions or data structures and can be accessed by a computer, and can also be a combination of multiple memories. The above-mentioned machine-executable program 43 can be downloaded from a computer-readable storage medium to a corresponding computing/processing device or downloaded to a computer or an external storage device via a network (such as the Internet, a local area network, a wide area network, and/or a wireless network).

In some embodiments, the air conditioner indoor unit 1 is a cabinet type air conditioner indoor unit. When the air-conditioning indoor unit 1 is a cabinet-type air-conditioning indoor unit, the air outlet 11 of the casing 10, the air outlet of the air uniform device 20, and the air outlets of the two heat exchange and air supply units 13 are usually vertically extending strips. The air outlet can basically cover the user's activity area in the vertical direction, and there is basically no need to adjust the air outlet direction in the vertical direction. At this time, the rotation direction of the wind evening device 20 may be limited to the horizontal direction, that is, rotation in the left and right directions. At this time, the air evening device 20 can rotate around a vertically extending rotating shaft, and the rotating shaft is located at the rear side of the air evening device 20 , so as to adjust the air supply direction of the air outlet at the front side of the air evening device 20 .

In some other embodiments, the air conditioner indoor unit 1 is a wall-mounted air conditioner indoor unit. When the air-conditioning indoor unit 1 is a wall-mounted air-conditioning indoor unit, its installation position is relatively high, and it is difficult to cover the user's activity area in the vertical direction, and the user's activity area in the horizontal direction is wider. The direction of rotation may include lateral and up-down directions.

In some embodiments, the air conditioner indoor unit 1 further includes a human body humidity detection device 50 and a human body position detection device 60 . The human body humidity detection device 50 is arranged on the casing 10 for detecting the humidity of the human body. The human body position detection device 60 is disposed on the casing 10 and is used for detecting the position of the human body.

In some embodiments, the air conditioner indoor unit 1 further includes a driving mechanism 70 , which is disposed on the casing 10 and connected to the air uniform device 20 to drive the air uniform device 20 to rotate.

Specifically, the driving mechanism 70 includes a motor disposed on the upper part of the casing 10 , and the output shaft of the motor is coaxially connected with the rotation shaft of the wind uniform device 20 . Of course, in some other embodiments, the driving mechanism 70 may also include a transmission mechanism connected with the motor, so as to transmit the driving force output by the motor to the rotating shaft of the wind uniform device 20 through the transmission mechanism.

Fig. 9 is a schematic structural diagram of a water washing device 30 according to an embodiment of the present invention. In some embodiments, the airflow in the water washing device 30 flows toward the drum along the radial direction of the drum 32 . That is, the air flow is directed perpendicular to the axis of rotation of the drum. The drum may include a horizontally extending rotating shaft 321 and a plurality of rotating discs 322 arranged at intervals on the rotating shaft 321, so that when the drum rotates, the rotating discs 322 may be used to take out the water in the water storage tank 31, so that when the air flows through When the gap between two adjacent rotating disks 322 flows through the drum, the water attached to the rotating disks 322 is used to wash, purify and/or humidify the airflow. The rotating disk 322 can provide a reliable and large contact area for the airflow and water, and the distribution of water on the rotating disk 322 is relatively uniform, so it can ensure sufficient and effective contact between the water and the airflow. Moreover, the arrangement of multiple rotating disks 322 can ensure that the airflow flowing through the drum can contact with water, which improves the purification effect and efficiency of the airflow.

It can be understood that the height of the drum 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 a part of the drum is above the water surface of the water storage tank 31 so that at least a part of the drum is in the air flow. In the flow path, when the water in the water storage tank 31 reaches the lowest water level, at least a part of the drum is submerged in water so that the water can be taken out when the drum rotates.

Further, a plurality of slits may be formed on the end surface of the rotating disk 322 to improve the ability of the rotating disk 322 to hold water and the amount of water brought out, thereby improving the purification efficiency and effect.

Furthermore, a plurality of honeycomb holes can also be opened on the rotating disk 322, and the honeycomb holes hold a relatively large amount of water, so the amount of water brought out from the rotating disk 322 can be increased, and the purification effect and purification efficiency of the airflow can be improved.

In some embodiments, a sterilizing device for sterilizing and deodorizing the water in the water storage tank 31 may also be provided in the water storage tank 31 . The sterilizing device may be a sterilizing bottle, an ultraviolet generating device, or the like.

In some embodiments, the water washing device 30 is located below the air equalizing device 20 and the two heat exchange and air supply units 13, so that the water washing device 30 will not occupy the space in the lateral direction and increase the lateral size of the air conditioner indoor unit 1, Therefore, the water washing device 30 , the air equalizing device 20 and the two heat exchange and air supply units 13 arranged in this way are more suitable for cabinet-type air conditioner indoor units. The top of the water washing device 30 is provided with an air outlet 33, and the bottom of the air uniform device 20 is provided with an air outlet 21, and the air outlet 33 is sealed and communicated with the air outlet 21 to avoid air leakage at the interface between the two.

Further, the area of the air outlet 33 is larger than the area of the air introduction port 21 . The air outlet 33 and the air introduction port 21 are arranged so that the projection of the air introduction port 21 in the horizontal plane is always in the projection of the air outlet 33 in the horizontal plane during the rotation of the air uniformity device 20 .
